Cherry, Phillip Warren. "A projection of motor fuel tax revenue and analysis of alternative revenue sources in Georgia." Thesis, Georgia Institute of Technology, 2012. http://hdl.handle.net/1853/43679.
Full textAbstract:
Transportation funding is critical to maintaining the assets that provide mobility for the movement of Georgia's people and goods. Currently, most of Georgia's transportation revenue is provided by the motor fuel tax. Inflation and recent increases in fuel economy have decreased fuel tax revenue in Georgia and weakened the Georgia Department of Transportation's (GDOT)'s ability to maintain and expand its transportation network.
This thesis synthesizes factors from literature that affect motor fuel tax revenue. These include demographic, economic, technological, and environmental forces that influence travel behavior and vehicle fuel economy.
A model was then created that incorporated these factors to model GDOT's 2009 fuel tax revenue and then project revenue in 2020 and 2030. The model uses an input/output structure that segments the fleet into personal, freight, and transit categories. User inputs, historical data, and projections are linked via relationships and feedback loops to project travel and fuel tax revenue forward. Because a near-infinite number of scenarios exist, conservative and aggressive scenarios were created for 2020 and 2030 scenarios that output revenue on an absolute, per-mile, and per-capita basis for comparison with more recent revenues.
The model outputs predict marginal declines in revenue by 2020 and significant declines by 2030. In response to these declines, the thesis evaluates methods of increasing transportation revenue. These methods include increasing the fuel tax, incorporating a VMT-fee, and widespread tolling measures. After evaluation, a policy recommendation is provided for how to best implement revenue strategies.

Jester, Hal J. "State lotteries as revenue sources for public elementary and secondary education." Virtual Press, 1990. http://liblink.bsu.edu/uhtbin/catkey/720313.
Full textAbstract:
The purpose of the study was to investigate the effectiveness of state lotteries as sources funding for public elementary and secondary education. The population consisted of 39 executive directors from state school board associations and the District of Columbia.A questionnaire of 22 items addressing lottery adoption, operation, performance, revenue dedication and distribution, proponent expectations, and school board member expectations was utilized. The questionnaire focused upon seven basic research questions.Findings1. Legislators in twenty-two states formally approved state lotteries between 1971 and 1989.2. Thirteen (fifty-nine percent) of twenty-two state lotteries in operation were approved by state legislatures between 1985 and 1989.3. Proponents in fifteen (73 percent) of adopting states cited "benefits to special interest groups" as an adoption rationale.4. Legislatures in four states dedicated 100 percent of lottery revenues to public elementary and secondary education.5.Fiscally successful lotteries have effective marketing and good organization/structure.6. The fiscal success of lotteries was limited by a multitude of factors, none of which represented more than 27 percent of responses.7. Measurement of lottery revenues to education was difficult due to the methods of distribution, and sparse data.8. Four of six state lotteries have revenues dedicated to education distributed funds through equalization grants.9. Lottery revenues met or exceeded the expectations of 81 percent of proponents.10. Lottery revenues to education met the expectations of 22 percent of school board members.11. Proponents in states where a lottery had been considered but not adopted cited each of three rationales 65 percent of the time. The rationales were: 1) lottery participation is voluntary, unlike a tax, 2) lotteries raise state revenue without raising taxes, and 3) benefits to special interest groups.12.Opponents in states where the legislature had considered but not adopted a lottery cited the rationale "lotteries are morally wrong" 100 percent of the time.

Rozelle, Zachari D. "Nontraditional revenue sources being used by Indiana school corporations and Indiana high schools." Virtual Press, 2006. http://liblink.bsu.edu/uhtbin/catkey/1336624.
Full textAbstract:
Nontraditional revenue is the term used to describe sources of funding other than those provided by federal and state support, including grants, and those provided by local property tax levies. Examples included licensing agreements, advertising in school facilities and on school property, school business partnerships, booster clubs, education foundations, and user fees. The purpose of this study was (1) to identify the sources of nontraditional revenue used by Indiana school corporations and Indiana high schools, (2) to assess local school officials' attitudes and expectations regarding the use of nontraditional revenue, and (3) to provide some insight as to how Indiana school corporations and schools utilize those funds.A QUAN-Qual Model was used for this study. The QUAN-Qual Model enabled the researcher to conduct the study in two phases. The first phase was comprised of a survey instrument used to identify the kinds of nontraditional revenue being used and to collect data regarding the amounts of nontraditional revenue being generated. The instrument was also used to measure attitudes towards nontraditional revenue and the perceived importance of those funds. The second phase was comprised of qualitative data collection through telephone interviews with school corporation and high school administrators conducted in February and March 2006. Analysis and interpretation of that data provided additional information about attitudes towards nontraditional revenue and how those funds are used.All Indiana school corporations and high schools that were included in the study utilized nontraditional revenue sources to varying degrees. They supplemented traditional funding with licensing agreements, school-business partnerships, booster clubs, education foundations, individual donations, and user fees. Nontraditional sources of revenue were identified as being essential for supporting some activities and programs. However, the researcher's sampling of corporation level administrators' and high school principals' attitudes regarding that revenue suggested that neither group relied on it to provide for essential personnel or programs. Statistically significant data suggest that school corporations and schools located in rural settings might be at a disadvantage with respect to their capacity to generate nontraditional revenue.Department of Educational Leadership

Full textAbstract:
Although nonprofit organization (NPO) leaders play crucial roles in society, financial distress and vulnerability are common for many NPO leaders, with some NPOs closing as a result of these conditions. The purpose of this single-case study was to explore the diversification strategies used by 10 leaders and senior staff of an NPO in the mid-Atlantic region of the United States through the conceptual lens of Markowitz's modern portfolio theory. Data were collected through in-depth semistructured interviews and analysis of organizational documents, internal archival data, social media, literature, and online databases. Through thematic analysis, 7 revenue diversification themes emerged: adding revenue streams; establishing an operating reserve; establishing positive financial performance; achieving financial stability, sustainability, organizational capacity, and organizational resilience; using transparency; achieving efficiency and organizational effectiveness; and using a marketing strategy. Additionally, 7 key themes emerged: documenting and implementing systematic processes, developing an approach to process improvement, implementing cross-department action plans, increasing transparency, reversing the adverse trend in forum participation, building a data-management system, and increasing individual and organizational capacity. These findings have implications for positive social change, in that they may offer NPO executives new insights and strategies to support revenue diversification, thereby helping them to reduce volatility in funding, decrease financial risk, avoid dependence on sole-source revenue, and identify opportunities to increase flexibility in support of organizational goals and objectives to increase services.

Lawson, Albertha H. "A Study of the Relationship Between Revenue Sources and Undergraduate Students' Graduation Rates at Public Research Universities." ScholarWorks@UNO, 2011. http://scholarworks.uno.edu/td/1325.
Full textAbstract:
The public's demand for accountability will have a significant impact on research universities' revenue resources in the future. Driving the demand is a perceived lack of institutional productivity. Undergraduate students' graduation rates represent one product of public research universities. States have already latched onto these rates as a measure of institutional performance; and as a result, states have provided a basis for public research universities to use the relationship between dollars invested in the institution and undergraduate students' graduation rates to respond to accountability issues. Current research provides little insight into this relationship. Research in this study uses concepts from the higher education production function, the resource dependency theory, and the Principal-Agent Model to investigate undergraduate students' four-year and six-year graduation rates as an institutional product. The research provides a greater degree of transparency into the relationship between dollars invested in public research universities and undergraduate students' graduation rates than has previously been shown. As a result of this relationship analysis, the research enables the development of a model for predicting undergraduate student graduation rates relative to dollars invested in the institution from different sources.

Full textAbstract:
Doutoramento em Ciências SociaisSocio-economic changes, alterations in societal expectations and new public policies have put pressures on higher education public funding, bringing the issue of funding diversification to the forefront. Income diversification, namely, generation of funds from private, as well as from competitive public sources, has become increasingly important in European higher education due to a complex financial environment and perceived deficit of innovation transfer. Although there are numerous studies about changes in national funding systems and allocation mechanisms, few have focused on diversification of funding sources, especially in the European context, making Portugal no exception. Thus, this study aims at exploring income diversification at the institutional level and its influence on the internal organisational structures. For this purpose two Portuguese public universities were chosen as case studies. The empirical material was collected through semi-structured interviews with top management and middle management of each university and through documentary analysis. Data analysis demonstrated that both universities are in the process of institutionalizing and formalising practices of income diversification, notably by getting more professional in how they are dealing with external stakeholders, such as businesses, local community, and students. However, the study also revealed that there is no formal, organised strategy to deal with income diversification. In general, the universities are reacting to external demands rather than pro-actively exploring opportunities. In this respect, the analysis determined several factors that promote or inhibit income diversification activities. Quality and favourable organizational culture were named by the interviewees as the most relevant factors for successful income diversification. External factors such as legal arrangements and funding conditions were cited as major constraints. This research has also revealed that revenue diversification activities tend to develop along the continuum towards higher sophistication and systematisation of activities that are supported by a powerful infrastructure. Together with efforts at the institutional level, the role of government policies proves to be crucial in providing tools and incentives to higher education institutions and creating a harmonious higher education system.
As mudanças socioeconómicas, as alterações nas espectativas sociais e novas políticas públicas têm posto uma enorme pressão sobre o financiamento público do ensino superior, trazendo a questão da diversificação do financiamento para o primeiro plano. Diversificação de financiamento, nomeadamente, a geração de receitas próprias de fundos provados, bem como de financiamento competitivo público, tornou-se cada vez mais importante no ensino superior Europeu, devido a um ambiente financeiro complexo e a défice de transferência de inovação. Embora existam numerosos estudos sobre mudanças nos sistemas nacionais de financiamento do ensino superior e mecanismos da distribuição do mesmo, poucos têm-se centrado na questão de diversificação das fontes de financiamento, especialmente no contexto Europeu e também em Portugal. Assim, este estudo pretende explorar a diversificação de financiamento ao nível institucional e sua influência sobre as estruturas organizacionais das universidades. Para este efeito, duas universidades públicas Portuguesas foram escolhidas como estudos de caso. Os dados foram recolhidos através de entrevistas semi-estruturadas com membros de Reitoria e Diretores de Departamentos e Faculdades, bem como da análise documental. A análise de dados mostrou que ambas as universidades encontram-se em processo de institualização e formalização de práticas de diversificação de financiamento, nomeadamente ficando mais profissionais em lidar com agentes externos, tais como as empresas, a comunidade local e os estudantes. No entanto, o estudo também revelou que não há uma estratégia formal, organizada para lidar com a diversificação de financiamento. Em geral, as universidades estão a responder a procura externa, em vez de explorar pró-activamente as oportunidades. Em relação a isto, a análise de dados determinou vários fatores que promovem ou inibem atividades de diversificação de financiamento. Qualidade e cultura organizacional favorável foram nomeadas pelos entrevistados como os fatores mais relevantes a diversificação de financiamento bem-sucedido. Fatores externos, como enquadramento jurídico e condições de financiamento foram citados como principais constrangimentos. O estudo também revelou que as atividades de diversificação de fontes de financiamento tendem a desenvolver ao longo do continuum em direção a maior sofisticação e sistematização das atividades suportadas por uma infraestrutura sólida. Juntamente com os esforços a nível institucional, o papel das políticas governamentais prova ser crucial no fornecimento de ferramentas e incentivos para as instituições do ensino superior e a criação de um sistema de ensino superior harmonioso.

Full textAbstract:
The purpose of this study was to determine how public two-year colleges in Tennessee internally budgeted and expended their unrestricted educational and general (E&G) funds from fiscal years 1988-89 through 1997-98. The primary focus was on the 14 Tennessee Board of Regents (TBR) community colleges and the internal allocation of expenditures by function from 1988-89 through 1997-98. A limited functional expenditure comparison was made with data from the National Association of College and University Business Officers' (NACUBO) comparative financial analysis for fiscal years 1993-94 and 1994-95 as well as with the Integrated Postsecondary Education Data System (IPEDS) survey for the 1996-97 fiscal year. The study examined whether the TBR community colleges were apportioning a larger percentage of their budgets for direct instruction and less for administrative support services in 1997-98 versus 1988-89. The analysis also examined staffing patterns relative to FTE enrollment, changes in revenue patterns for the four major sources of unrestricted E&G funds, and tuition increases. A portion of the analysis included comparisons between current and constant dollars to measure the real gain or loss in financial resources after allowing for inflation as measured by the Consumer Price Index (CPI). A primary research question underlying this study sought to determine if the public two-year colleges in Tennessee were operating more efficiently at the end of the research period regarding the internal allocation of budgeted funds. It was assumed that efficiency could be measured in terms of an increase in the percentage allocation of funds to direct instruction and a decrease in the percentage allocated to institutional support for general administration. In spite of a reduction in the share of state appropriations provided to higher education during the past decade, the TBR community colleges apportioned a larger percentage of their budgets for instructional cost in 1997-98 than in 1988-89. Conversely, these colleges expended a smaller portion of their budgets for administration at the end of the ten-year period. In conclusion to this study, recommendations are made to more effectively inform public policymakers and the general public as to the efficiency of Tennessee's public community colleges regarding the allocation of financial resources. Comparisons with national and Southern Regional Education Board data are also desirable. Public policymakers are encouraged to more critically examine the long-range benefits of an educated population and the forecast for technical skills required of the workforce in the 21st century.

Full textAbstract:
This thesis focuses on deaf people’s educational attainment, position on the labour market and sources of revenue. These issues are interrelated, for instance a higher level of educational attainment seems to be associated with a lower unemployment rate and higher levels of income. The national context is Sweden and the Swedish welfare state in 2005. All studies in the thesis compare a deaf population, consisting of 2,144 persons born between 1941 and 1980 who have attended a school for the deaf in Sweden, with a general reference population, consisting of 100,000 randomly chosen persons from the total Swedish population born between 1941 and 1980. Data for all studies consisted of registered information about the persons in the year 2005. The results show that there are differences between the deaf and the reference population regarding level of educational attainment, position on the labour market and sources of revenue and disposable income, with the deaf population having a poorer position than the reference population in all areas. There are also differences between the workplaces of the deaf and the people in the reference population, and it is twice as common for people in the deaf population than for people in the reference population to have a higher level of educational attainment than is required for their occupation. These differences between the deaf and the reference population cannot be associated with differences in the independent factors, as for instance sex, age and immigration background, for which the results have been adjusted. This thesis shows that being part of the deaf population appears to be of importance. Factors in conjunction with deafness that can increase our understanding of the differences between the deaf and the reference populations in an educational context, labour market context and economic context are discussed in the thesis.

nÃo hÃThe Federal Government, giving efficacy to section III of  4 of art. 153 of the Federal Constitution enacted Law No. 11,250, of december 27, 2005, which provides that the Union, through an agreement, delegate responsibility for monitoring and collection for the Municipalities and the Federal District on the Rural Land Tax (ITR). By adhering to the agreement, the cities appropriated the entire revenue of ITR, paying, however, with the cost of administering them. Without membership, municipalities receive the transfer equivalent to 50% of the proceeds. This study aims to evaluate the potential of revenue collection ITR considering various scenarios of tax administration costs, serving as a resource for decision-making of the city manager about the adherence agreement with the Union For this, we used data agricultural census 2006 for 184 municipalities in the Cearà linear regression model of OLS. As a result, it was found that characteristics such as the Gini index, the total area of establishments (crop, pasture, woods and forests, agroforestry and so residual) value of goods and livestock area of influence on the collection of ITR. It is presented as a consequence, the potential revenue collection of the tax to municipalities on the basis of the Cearà cost scenarios considered.
O Governo Federal, dando eficÃcia ao inciso III do  4 do art. 153 da ConstituiÃÃo Federal, editou a Lei n 11.250, de 27 de dezembro de 2005, que prevà a possibilidade de a UniÃo, por meio de convÃnio, delegar competÃncia de fiscalizaÃÃo e arrecadaÃÃo para os MunicÃpios e o Distrito Federal, quanto ao Imposto Territorial Rural (ITR). Ao aderirem ao convÃnio, os municÃpios apropriam a totalidade da receita de ITR, arcando, porÃm, com os custos de administrÃ-los. Sem a adesÃo, os municÃpios recebem o repasse equivalente a 50% do arrecadado. Este trabalho tem como objetivo avaliar o potencial arrecadatÃrio do ITR, considerando diversos cenÃrios de custos de administraÃÃo do tributo, servindo como subsÃdio para a tomada de decisÃo do gestor municipal acerca da adesÃo ao convÃnio com a UniÃo. Para tanto, utilizou-se dados do Censo AgropecuÃrio 2006, para os 184 municÃpios Cearenses, em modelo de regressÃo linear de mÃnimos quadrados ordinÃrios. Como resultado, constatou-se que caracterÃsticas como o Ãndice de Gini, a Ãrea total dos estabelecimentos (lavoura, pastagem, matas e florestas, sistema agroflorestal e de forma residual), valor dos bens e Ãrea de produÃÃo animal exercem influÃncia sobre a arrecadaÃÃo do ITR. Apresenta-se, como consequÃncia, o potencial arrecadatÃrio do tributo para os municÃpios Cearenses em funÃÃo dos cenÃrios de custos considerados.

In this dissertation, we focus on dynamic analyses that examine the data handled by programs and operating systems in order to divine the undocumented constraints and implementation details that determine their behavior in the field. First, we introduce a novel technique for uncovering the constraints actually used in OS kernels to decide whether a given instance of a kernel data structure is valid. Next, we tackle the semantic gap problem in virtual machine security: we present a pair of systems that allow, on the one hand, automatic extraction of whole-system algorithms for collecting information about a running system, and, on the other, the rapid identification of “hook points” within a system or program where security tools can interpose to be notified of security-relevant events. Finally, we present and evaluate a new dynamic measure of code similarity that examines the content of the data handled by the code, rather than the syntactic structure of the code itself. This problem has implications both for understanding the capabilities of novel malware as well as understanding large binary code bases such as operating system kernels.

Full textAbstract:
La mondialisation de l’économie, le développement des moyens de transport et de communication et l’émergence des paradis fiscaux rendent la connaissance de la fiscalité d’autres pays indispensable, tant par le fiscaliste praticien que par le chercheur.La France et la Belgique ont une communauté de langue et de culture en plus de la proximité géographique. Connaître sa fiscalité et la comparer à la fiscalité française est utile à tout fiscaliste qui pourra alors se faire sa propre idée sur le statut de paradis fiscal qu’on lui attribue. Nous avons choisi de comparer l’imposition des revenus étrangers car, ceux qui changent de pays pour éviter la pression fiscale, sont souvent des personnes ayant une forte activité internationale. En l’absence de convention préventive de double imposition, l’imposition de tels revenus est plus favorable en France, quand ils sont encaissés par des personnes morales. En revanche, lorsqu’ils sont encaissés par des personnes physiques, l’imposition est plus avantageuse en Belgique.Mais les deux pays ont conclu beaucoup de conventions préventives de double imposition de sorte qu’il est difficile de trouver un pays qui ne leur est pas lié par une convention fiscale. Or, il s’avère que la Belgique, à travers ses conventions, adopte des mesures fiscales nettement plus favorables que la France et ce, afin de favoriser l’expansion économique de ses résidents et attirer aussi des capitaux étrangers.A cette situation, s’ajoute le fait que ce pays autorise des montages fiscaux qui seraient sanctionnés en France sous l’angle de l’abus de droit.On comprend alors pourquoi certains hommes d’affaires n’hésitent pas à s’y domicilierAccording to several factors such as the economy globalization, the development of transportation and communication supplies and the rising of tax heavens, tax lawyers have to reach a high expertise and knowledge of foreign tax systems.Belgium and France share common roots of language and culture in addition to the geographical proximity. To be especially aware of the Belgium tax law scheme is absolutely necessary for every tax lawyer in particular in a view to compare and have an opinion about the heaven nature of the Belgian system.As far as it is impossible to compare every point of the two systems, we decided to focus only on the taxation of foreign income, because of the international activity of the taxpayers willing to lower the tax pressure. Without an international tax treaty, foreign incomes are less taxed in France when they are received by a company but the situation is different when the receiver is a person. However it has to be noticed that Belgium and France have developed a huge international tax treaty network. The Belgium one is analyzed as being more attractive for foreign investments and national economic expansion. Besides, Belgium has a tax system which authorizes tax schemes seen sometimes as an abuse of right in France. As a consequence the exile of business men can be understood

MBA Professional ReportThe purpose of this research is to analyze the level of emphasis placed on the Corporate Social Responsibility (CSR) categories (health and safety, environment, diversity, human rights, discretionary, and corporate) between defense contractors and companies that receive the majority of their revenues from commercial sources. Five companies were selected from each of the following three groups: defense contractors, top CSR companies, and largest companies from a diverse industry base. The results indicate that defense contractors place less emphasis on the CSR categories than those companies that receive their revenues from commercial sources. Specifically, defense contractors were rated lower in the human rights and corporate categories. This exploratory study establishes a foundation for future research in the relationship between CSR principles and defense contractors.

Full textAbstract:
Gene Regulatory Networks (GRNs) represent how genes interact in various cellular processes by describing how the expression level, or activity, of genes can affect the expression of the other genes. Reverse-engineering GRN models can help biologists understand and gain insight into genetic conditions and diseases. Recently, the increasingly widespread use of DNA microarrays, a high-throughput technology that allows the expression of thousands of genes to be measured simultaneously in biological experiments, has led to many datasets of gene expression measurements becoming publicly available and a subsequent explosion of research in the reverse-engineering of GRN models. However, microarray technology has a number of limitations as a data source for the modelling of GRNs, due to concerns over its reliability and the reproducibility of experimental results. The underlying theme of the research presented in this thesis is the incorporation of multiple sources and different types of data into techniques for reverse-engineering or learning GRNs from data. By drawing on many data sources, the resulting network models should be more robust, accurate and reliable than models that have been learnt using a single data source. This is achieved by focusing on two main strands of research. First, the thesis presents some of the earliest work in the incorporation of prior knowledge that has been generated from a large body of scientific papers, for Bayesian network based GRN models. Second, novel methods for the use of multiple microarray datasets to produce Bayesian network based GRN models are introduced. Empirical evaluations are used to show that the incorporation of literature-based prior knowledge and combining multiple microarray datasets can provide an improvement, when compared to the use of a single microarray dataset, for the reverse-engineering of Bayesian network based GRN models.

Renewable power generation from the controlled mixing of sea and fresh water is relatively unexplored when compared to the development for solar, wind, and other sustainable power alternatives. When global river discharge was taken into account, an estimated 2.6 TW of obtainable energy exists in untapped salinity gradients. Reverse electrodialysis is one proposed power-generating mechanism for harnessing energy from brackish environments and relies on the transport of aqueous salt ions through an apparatus of ion-exchange membranes. In this thesis, operational parameters, including flow direction, salinity composition, and membrane selectivity, are investigated. For optimal performance, I have employed counter-current flow mode with monovalent ion selective membranes and pure 0.5 M NaCl saline solution. The results show that a maximum open circuit voltage (OCV) level of 2.01 V is obtained with an active membrane area of 0.0756 m². The presence of multivalent ions in the feed solutions hinders OCV levels, but the effects are reduced with monovalent-selective membranes. Preliminary results are insightful; in order to increase the commercially viability of this technology, future work is needed to enhance the performance properties of the ion exchange membranes.

Full textAbstract:
This work deals with the problem of reverse audio engineering for active listening. The format under consideration corresponds to the audio CD. The musical content is viewed as the result of a concatenation of the composition, the recording, the mixing, and the mastering. The inversion of the two latter stages constitutes the core of the problem at hand. The audio signal is treated as a post-nonlinear mixture. Thus, the mixture is "decompressed" before being "decomposed" into audio tracks. The problem is tackled in an informed context: The inversion is accompanied by information which is specific to the content production. In this manner, the quality of the inversion is significantly improved. The information is reduced in size by the use of quantification and coding methods, and some facts on psychoacoustics. The proposed methods are applicable in real time and have a low complexity. The obtained results advance the state of the art and contribute new insights.

Full textAbstract:
Un manuscrit du XIVe siècle, le « Livre des revenus et dépenses de l’abbaye de Cluny », présente un cas de figure unique. Ne correspondant à priori à aucune typologie classique à la comptabilité ou, plus largement, à la production écrite médiévale, on voit dans son texte une volonté d’établir une évaluation idéelle, atemporelle des recettes, dépenses et taxations de l’ordre et de l’abbaye. Par la production d’une comptabilité idéalisée, les clunisiens conçoivent une base normale, un fondement référentiel aux finances de l’ordo Cluniacensis devant servir à en baliser la gestion. Par l’analyse des données de ce manuscrit, on se plonge directement dans les considérations du pitancier relatives à la gestion de l’ordre, paneuropéen, et aux difficultés financières auxquelles sont soumises les dépendances de Cluny. De même, par sa liste de dépenses, ce codex fournit un rarissime témoignage de l’approvisionnement et de la vie intérieure de Cluny au XIVe siècle.

Full textAbstract:
Much of the software in the world today was developed from the mid-1960s to the mid- 1970s.This legacy software deteriorates as it is modified to satisfy new organizational requirements. Currently, legacy system maintenance requires more time than new system development. Eventually, legacy systems must be replaced. Identifying their functionality is a critical part of the replacement effort. Recovering functions from source code is difficult because the domain knowledge used to develop the system is not routinely retained. The source code is frequently the only reliable source of functional information.
This dissertation describes functional process information recovery from COBOL source code in the military logistics system domain. The methodology was developed as an information processing application. Conceptual and logical models to convert source code to functional design information were created to define the process. A supporting data structure was also developed.
The process reverse engineering methodology was manually applied to a test case to demonstrate feasibility, practicality, and usefulness. Metrics for predicting the time required were developed and analyzed based on the results of the test case.
The methodology was found to be effective in recovering functional process information from source code. A prototype program information database was developed and implemented to aid in data collection and manipulation; it also supported the process of preparing program structure models. Recommendations for further research include applying the methodology. to a larger test case to validate findings and extending it to include a comparable data reverse engineering procedure.

Full textAbstract:
Visualization of digital geographic data is often accomplished through custom symbology that is saved in a proprietary format called a layer file (.lyr). The sharing of free geographical information system (GIS) data can be limited as the symbology data is bound inthe .lyr file format. This makes it harder and more tedious to work with open software tools since it is not possible to convert or open the .lyr file in free and open GIS software and thus limits the distribution of free GIS data. The aim of this thesis is to increase the interoperability of .lyr data between proprietary and free and open GIS software. This was done by revers eengineering the .lyr file format to document the file structure and to distribute the knowledge and metadata gained from this project to the open source community. Reverse engineering the.lyr format provided a well needed metadata and documentation about the format which increases the interoperability and enable future work to continue to lessen the gap between open source and commercial software. This groundwork can therefore, enable a continued development of data interoperability between proprietary and free and open GIS software.

Full textAbstract:
Ce travail porte sur le développement d'algorithmes et l'application de méthodes numériques pour la résolution des problèmes inverses d'estimation de paramètres, d'identification de conditions aux limites et d'identification de sources dans un milieu poreux. Ces outils seront d'une grande utilité pour l'aide à la gestion des ressources en eaux souterraines et à leur préservation quant aux dégradations. L'objectif de cette thèse est de résoudre ces problèmes inverses en se basant sur différentes approches : Une résolution basée sur l'optimisation de forme topologique qui est la recherche de la géométrie d'un objet qui soit optimale vis à vis d'un critère donné, et ce sans aucun a priori sur sa topologie, c'est-à-dire sur le nombre de "trous" qu'il peut contenir. Sachant que ces trous représentent les puits recherchés. Pour ce faire, nous avons adopté la méthode du gradient topologique, qui consiste à étudier le comportement d'une fonction objectif lors de la création d'un petit trou à l'intérieur du domaine. Une résolution basée sur la minimisation d'une fonctionnelle d'erreur en énergie en utilisant des données surabondantes sur une partie de la frontière du domaine afin de compléter les données sur toute la frontière du domaine et de déterminer les positions, les débits et le nombre de puits existants à l'intérieur du domaine. Une résolution par le couplage de la méthode de paramétrisation adaptative qui a l'avantage de minimiser le nombre des inconnus de paramètres permettant d'interpréter au mieux les données disponibles et la méthode du gradient topologique. Ce couplage nous permet à la fois d'identifier les zones géologiques, de déterminer les valeurs de la transmissivité hydraulique dans chaque zone et de localiser les positions des puitsThis work deals with the development of algorithms and application of numerical methods for solving inverse problems of parameters estimation, identification of boundary conditions and localisation of sources in porous media. These tools will be usefull in the management of groundwater resources and their preservation as to damage. The objective of this thesis is to solve the inverse problem based on different approaches: A resolution based on topological shape optimization is to find an optimal design without any priori assumption about its topology, that is, about the number of holes it may contain. Knowing that these holes represent the searched wells. To do this, we have adopted the method of topological gradient, which is to study the behavior of an objective function when creating a small hole inside the domain. A resolution based on the minimization of a constitutive law gap functional by using overspecified data on a part of the boundary of the domain to complete the data on all the boundary of the domain and determine the positions, the flows and the number of existing wells inside the domain. A resolution by the coupling of the adaptive parameterization method which has the advantage to minimize the number of the unknowns of parameters allowing to interpret at best the available data and the method of the topological gradient. This coupling allows us at the same time to identify the geological zones, to determine the values of the hydraulic transmissivity in every zone and to locate wells' positions

Full textAbstract:
La décentralisation des compétences en matière d’aide sociale depuis trois décennies maintenant aboutit-elle à une inégalité de traitement de ses bénéficiaires, accentuée par un phénomène de territorialisation du droit? Pourtant, la France, État unitaire, dont l’organisation est décentralisée, reste le pays des droits de l’Homme dont la devise Républicaine donne une place centrale à l’égalité en l’encadrant des mots liberté et fraternité. S’il est vrai que le pouvoir normatif de l’État central est toujours d’actualité puisqu’il fixe les règles concernant les prestations d’aide sociale légale, il n’en n’est pas moins vrai que les collectivités territoriales disposent également d’un pouvoir d’appréciation non négligeable quant aux conditions d’attribution des aides et de mise en œuvre des actions dans le domaine social. À telle enseigne, que l’on pourrait croire que l’État en se retirant progressivement du domaine de l’aide sociale dans lequel, d’ailleurs, il ne dispose plus que de compétences résiduelles, a peut-être perdu une partie de ses pouvoirs réels. Le grand gardien de la cause de l’égalité qu’est le Conseil Constitutionnel invoque la possibilité de créer des inégalités de traitement. Sommes-nous en train d’évoluer vers une autre forme d’État ? Ou alors faut-il reconnaitre que pour mieux répondre aux besoins sociaux, il faut admettre un traitement différencié des situations à l’instar de tout système de discrimination positiveThe processing’s inequality of social security benefit’s recipients according to their place of residence. Does the decentralization of skills regarding social security benefit, for three decades now, ends to a processing’s inequality of beneficiairies stressed by a territorialisation’s phenomenon of the law? Nevertheless, France, unitarian State, which organization is decentralized, remains the country of the human rights which republican slogan gives a central place to equality with the words of freedom and brotherhood. If it is true that the normative power of the central State is still the actuality by fixing rules concerning the services of social security, it is not less true that regions with a measure of autonomy also have a power of appreciation for the conditions of social security’s allocation and implementation of these actions. In such case, we could believe that the State by withdrawing gradually from the social assistance’s domain, in which he no longer had residual skills, maybe lost a part of its real powers. The “big guardian” of the equality’s cause, the Constitutional Council, refers to the possibility of creating processing inequalities. Are we developing to another shape of State? Or is it necessary to recognize that to answer to the social needs, we have to admit a differentiated processing by the situations following the example of any system of positive discrimination

Full textAbstract:
A UV Laser Induced Fluorescence (LIF) system, previously developed in our laboratory, was modified and used for a series of applications related to the development and optimization of UV LIF spectroscopic measurements of trace contaminants in drinking water and other water sources. Fluorescence spectra of a number of water samples were studied, including those related to the reverse osmosis water treatment and membrane fouling, domestic and international drinking water, industrial toxins, bacterial spores, as well as several fluorescence standards. Of importance was that the long term detection of the trace level of Dissolved Organic Compounds (DOC) was measured, for the first time to our knowledge, over a one week period and with a time resolution of 2.5 minutes. A comparison of LIF emission using both 266 nm and 355 nm excitation was also made for the first time. Such real-time and continuous measurements are important for future water treatment control.
The LIF system was modified to accommodate UV Light Emitting Diodes (LED) as alternative excitation sources, and tested for the detection of trace organic species in water. In addition, a compact system using LED excitation and a spectrometer was xviii developed and underwent initial testing.
The original LIF system had two laser sources, 266 nm and 355 nm. The additional sources incorporated in the system were UV LEDs emitting at 265 nm, 300 nm, 335 nm and 355 nm.
The LED spectral emission was studied in detail, in terms of spectral variability and power output. It was found that all LEDs had some emission in the visible spectrum, and an optical filter was used to remove it.
The signal-to-noise ratio for the LED-based systems was determined and compared with that of the LIF system. The fluorescent signal of the LED-based system was smaller by 1 to 2 orders of magnitude, despite the fact that the LED pulse energy was 2 to 3 orders of magnitude less than the laser's. As such, the fluorescent signal from the LED was greater than expected. Therefore, a UV LED may be a compact and much cheaper optical source for future water measurement instruments.

Full textAbstract:
Cette étude s’intéresse à la conception systémique intégrant simultanément les questions de dimensionnement et de gestion optimale de l'énergie. Le système étudié concerne un procédé de pompage intégrant un processus de dessalement d’eaux saumâtres alimenté par des sources de puissance hybrides renouvelable incluant un minimum de stockage électrochimique. Ce cas d’étude appartient à une classe typique de systèmes autonomes alimentés par des sources intermittentes dont profil de puissance a une forme "donnée" : « selon les conditions climatiques (ensoleillement, vent), avec un minimum de stockage d’électricité, la puissance offerte doit être convertie ou stockée hydrauliquement sous peine d’être gaspillée ». L'influence des conditions d'environnement et la robustesse du processus d’optimisation est enfin aussi discutée dans cette thèse. Deux types de modèles mathématiques, dynamiques et quasi-statiques, sont mis en œuvre pour décrire l'ensemble du dispositif. Le système est tout d’abord modélisé dynamiquement par Bond Graphs. Pour une simulation plus rapide, plus adaptée à l’optimisation globale du système, un modèle quasi-statique est créé pour être simulé dans l'environnement Matlab. Pour de tels dispositifs, étant donné une certaine puissance offerte au fil du vent et du soleil, trouver le point optimal de fonctionnement à chaque période consiste en un partage de puissance entre les sous systèmes de pompage et de traitement de l’eau : ce processus est plutôt complexe compte tenu des non linéarités (courbes rendement – puissance) et de la présence de nombreuses contraintes relatives aux limitations de puissance des pompes, aux conditions de niveau des réservoirs, ainsi qu’aux limitations de pression et de débit dans les processus hydrauliques (pompes osmoseur). Nous montrerons qu’il n’est pas si trivial de choisir une fonction objectif qui assure simultanément la performance et la robuste du système vis-à-vis des conditions d’environnement : une fonction objectif robuste quel que soit le profil de puissance des sources est ainsi proposée pour mettre en œuvre une gestion optimale de l’énergie. Le problème d’optimisation étant posé sous forme standard, consistant en la maximisation d’une fonction objectif sous contraintes, des approches d’optimisation efficaces par programmation non linéaire sont employées. La question du dimensionnement et son couplage à la gestion énergétique est finalement étudiée. En particulier, l’intérêt de la modularité des systèmes, considérant plusieurs pompes connectées en parallèle pour la même fonction, est investiguéThis study focuses on systemic design, integrating simultaneously issues of sizing and optimal energy management. The system under study consists of a pumping process including a brackish water desalination system fed by hybrid renewable power sources with minimum electrochemical storage. Such a device belongs to the class of “autonomous systems” supplied by intermittent sources whose power profile has a “given” waveform: “with minimum electrical storage, power has to be converted, stored in water tanks, or wasted following climatic (sun, wind) conditions”. Influence of environment conditions and robustness of the optimization process is then also discussed in this thesis. Both dynamic and quasi static models are implemented for representing the whole system. The device is firstly modeled dynamically by Bond Graph methodology. For faster simulations, which are more suitable for system optimization, a quasi static model is created to be simulated in the Matlab environment. For such systems, given a certain source power, finding optimal operation point at each period consists of a power sharing between all pumping devices: it is a complex process with huge nonlinearities (efficiency vs power curves) and with many constraints as for the limitation of pump powers, tank level conditions, or pressure and flow limitations in hydraulic network and pumping devices. It is not so trivial to define an objective function which ensures system performance and robustness versus environment conditions: a convenient objective function, whatever the input power profile, is then proposed to implement the optimal management. The optimization problem being mathematically expressed, consisting of objective function maximization under constraints, efficient optimization methods by non linear programming are implemented. The issue of sizing and its coupling with system management efficiency is finally studied. In particular, the interest of modular operation with several pumps connected in parallel is also concerned in this research

L’analyse de codes malveillants est un domaine de recherche en pleine expansion de par la criticité des infrastructures touchées et les coûts impliqués de plus en plus élevés. Ces logiciels utilisent fréquemment différentes techniques d’évasion visant à limiter la détection et ralentir les analyses. Parmi celles-ci, l’obfuscation permet de cacher le comportement réel d’un programme. Cette thèse étudie l’utilité de l’Exécution Symbolique Dynamique (DSE) pour la rétro-ingénierie. Tout d’abord, nous proposons deux variantes du DSE plus adaptées aux codes protégés. La première est une redéfinition générique de la phase de calcul de prédicat de chemin basée sur une manipulation flexible des concrétisations et symbolisations tandis que la deuxième se base sur un algorithme d’exécution symbolique arrière borné. Ensuite, nous proposons différentes combinaisons avec d’autres techniques d’analyse statique afin de tirer le meilleur profit de ces algorithmes. Enfin tous ces algorithmes ont été implémentés dans différents outils, Binsec/se, Pinsec et Idasec, puis testés sur différents codes malveillants et packers. Ils ont permis de détecter et contourner avec succès les obfuscations ciblées dans des cas d’utilisations réels tel que X-Tunnel du groupe APT28/SednitMalware analysis is a growing research field due to the criticity and variety of assets targeted as well as the increasing implied costs. These softwares frequently use evasion tricks aiming at hindering detection and analysis techniques. Among these, obfuscation intent to hide the program behavior. This thesis studies the potential of Dynamic Symbolic Execution (DSE) for reverse-engineering. First, we propose two variants of DSE algorithms adapted and designed to fit on protected codes. The first is a flexible definition of the DSE path predicate computation based on concretization and symbolization. The second is based on the definition of a backward-bounded symbolic execution algorithm. Then, we show how to combine these techniques with static analysis in order to get the best of them. Finally, these algorithms have been implemented in different tools Binsec/se, Pinsec and Idasec interacting alltogether and tested on several malicious codes and commercial packers. Especially, they have been successfully used to circumvent and remove the obfuscation targeted in real-world malwares like X-Tunnel from the famous APT28/Sednit group

SO2 emission factor for clamp kiln firing was obtained from “reverse-modelling”, a technique that
integrates ambient monitoring and dispersion modelling (using Atmospheric Dispersion Modelling
System software) to “standardize” actual emission rate from an assumed rate of 1 g/s. The use of
multiple point sources proved to improve the simulation of the buoyancy-induced plume rise;
therefore, a “bi-point” source configuration was adopted for the kiln. The “reverse-modelling”
technique and “bi-point” source configuration produced SO2 emission rates differing from -9 % to
+22 % from mass balance results, indicating that the “reverse-modelling” calculations provide
reliable emission estimates for SO2.
An NO2 emission factor could not be obtained from the “reverse-modelling” technique due to
experimental errors and the significant effect of NO2 emissions from other onsite air emission
sources such as internal combustion engines. The NO2 emission factor was obtained from previous
comprehensive study on a similar clamp kiln site.
The emission factors obtained from this study were utilized in developing an “emission inventory
tool” which is utilized by clay brick manufacturers in quantifying air emissions from their sites.
Emissions quantification is a requirement for brick manufacturers to obtain an AEL which is
regulated under South African environmental laws.
It is suggested that the technique used here for SO2 emission confirmation could be used to
estimate emissions from a volume or area source where combustion occurs and where knowledge
of the source parameters is limited.Dissertation (MSc)--University of Pretoria, 2013.

Tout se traduit par l’émergence et la consolidation d’un modèle agri-rural basé sur une vaste gamme de ressources agricoles et extra-agricolesAfter more than two decades and following a difficult rupture and transition from communist regime, Albanian rural area and rural households have undergone multiple rapid transformations. While agriculture is facing several limits (the extremely small and fragmented farms, the unresolved issue of land property, the insufficiency of infrastructure, the low access to commercial circuits, etc.), the expectations of rural households in terms of product and service accessibility, well-being and life quality have lead to the emergence of different forms of economic adaptation, mostly through the implementation of activity and income diversification strategies. The trajectories of rural households based on the valorization of agricultural resources or non agricultural alternatives, are analyzed according to their diversity and local context. Family structure represents the organizing and operational foundation of these trajectories.

Sukcinimidi su jedinjenja koja pokazuju višestruke farmakološke efekte uključujući i antiproliferativnu aktivnost, zahvaljujući prisustvu farmakofore sa dva hidrofobna regiona i dva regiona bogata elektronima. Savremeni dizajn lekova ima za cilj da se modifikacijama u strukturi (promena vrste, položaja i orijentacije supstituenata) i in silico računarskim metodama predvide i optimizuju farmakokinetske osobine i bezbednosni profil kandidata za lek. U ranoj fazi razvoja lekova se koriste postojeće baze podataka o molekulskim, farmakokinetskim i toksikološkim parametrima već ispitanih jedinjenja i pomoću matematičkih modela i algoritama predviđaju se osobine novih molekula, eliminišu se neodgovarajući kandidati i postiže se ušteda u vremenu i materijalnim sredstvima. Da se ispitaju fizičko-hemijske karakteristike 11 novosintetisanih metil-etil-N-aril-sukcinimida na osnovu strukture, primenom različitih softverskih paketa; da se na osnovu strukture odrede farmakokinetski i toksikološki parametri, primenom različitih softverskih paketa; da se ispita retenciono ponašanje, odnosno odrede retencione konstante za svako jedinjenje primenom visokoefikasne hromatografije na tankom sloju (HP-TLC) i ispita mogućnost primene retencionih konstanti kao mere lipofilnosti ispitivanih jedinjenja; da se ispita antiproliferativna aktivnost na odabranim kulturama ćelija karcinoma i na zdravim ćelijama fibroblasta pluća; da se analizom molekulskog dokinga ustanovi vezivanje za estrogene receptore. Ispitano je retenciono ponašanje 11 novosintetisanih derivata sukcinimida primenom visokoefikasne hromatografije na tankom sloju (HP-TLC) obrnute faze uz primenu dvokomponentne smeše vode i organskog rastvarača (metanola, acetonitrila ili acetona), sa odgovarajućim zapreminskim udelom organskog rastvarača kao mobilne faze. Iz razvijenih hromatograma su izračunate retencione konstante RM0 i S. Logaritam podeonog koeficijenta (logP) određen je in silico, korišćenjem različitih računarskih programa. In silico su određene fizičko-hemijske karakteristike, farmakokinetski parametri, toksikološki parametri, akvatična toksičnosti i afinitet vezivanja za estrogene receptore. Izračunate su vrednosti afiniteta za 4 vrste receptora (G-protein spregnuti receptori, jonski kanali, inhibitori kinaza, nuklearni receptori). Antiproliferativna aktivnost ispitivanih derivata sukcinimida određena je primenom kolorimetrijskog testa sa tetrazolijum solima (MTT testa) na komercijalnim kulturama ćelija (MRC-5, A549, HeLa, MDA-MB-231, MCF-7, HT-29) i izračunate su IC50 vrednosti. Urađena je i doking analiza sukcinimida prema ERA (estrogen receptor alfa) i ERB (estrogen receptor beta) i dobijene su vrednosti energije formiranja kompleksa sa posmatranim receptorima (MolDock Score). Statistički najznačajnije linearne korelacije dobijene su između eksperimentalno određenih hromatografskih parametara (RM0 i S) i in silico parametara lipofilnosti MlogP i ClogP. Ispitivanjem uticaja promene RM0 i S na farmakokinetske karakteristike dobijeni su rezultati koji pokazuju paraboličnu zavisnost konstante apsorpcije (Ka) i procenta vezivanja za proteine plazme (PPB) od posmatranih retencionih konstanti, dok je zavisnost sa volumenom distribucije (Vd) i sposobnošću prolaska kroz krvno-moždanu barijeru (logBBB) bila linearnog tipa. Toksičnost ispitivanih jedinjenja, procenjena na osnovu in silico dobijenih LD50 vrednosti, nije bila viša od toksičnosti već registrovanih lekova sa strukturom sukcinimida, i dala je parabolične zavisnosti u odnosu na RM0 i S vrednosti. Eksperimentalno nijedno od ispitivanih jedinjenja nije pokazalo aktivnost u odnosu na zdrave fibroblaste pluća. Najznačajniju antiproliferativnu aktivnost (najniže IC50) su pokazala jedinjenja 6 i 7 u odnosu na ćelije linije MCF-7 i jedinjenje 11 u odnosu na A549 ćelijsku liniju. Doking analiza je pokazala niže energije formiranja kompleksa sa ERA, u odnosu na ERB. Eksperimentalno određeni parametri RM0 i S se mogu koristiti kao alternativne i pouzdane mere lipofilnosti analiziranih sukcinimida. Ispitivana jedinjenja pokazuju povoljne fizičko-hemijske karakteristike, predviđene in silico metodama i povoljne farmakokinetske karakteristike: male vrednosti konstante apsorpcije, umeren volumen distribucije, povoljan afinitet vezivanja za proteine plazme, favorizovan prolazak kroz krvno-moždanu barijeru za lipofilnija jedinjenja. Procenjuje se da sva ispitivana jedinjenja, izuzev derivata sa –CN supstituentom, imaju zahtevani nizak stepen toksičnosti. Po antiproliferativnoj aktivnosti u odnosu na ćelije ER-zavisnog karcinoma dojke (MCF-7) izdvajaju se jedinjenja sa metil i nitro supstituentom u para položaju. Na osnovu malih energija formiranja kompleksa sa ERA, koji su eksprimirani na ćelijama MCF-7 linije, pretpostavlja se da bi mehanizam njihovog delovanja delimično mogao biti objašnjen uticajem na ERA, ali su potrebna dodatna istraživanja na tom polju.Succinimides have exhibited various pharmaceutical effects including antiproliferative activity due to an important structural fragment (a pharmacophore) presented in form of two hydrophobic regions and two electron-rich centers. Current development of new drugs involves modifications in structure (type, position and orientation of substituents) and usage of in silico computational programs to predict and optimize pharmacokinetic and safety profile of drug candidates. In early phase of drug development, databases regarding the molecular, pharmacokinetic and toxicological parameters of already tested compounds are used, mathematical models and algorithms are applied for predicting the properties of new molecules and inadequate candidates are eliminated saving time and resources. Determination of physico-chemical properties of the analyzed methyl-ethyl-N-phenilsuccinimide derivatives by software packages; virtual pharmacokinetic and toxicology screening; investigation of retention behavior of the compounds by the reversed-phase HPTLC analysis and calculation of retention constants and their correlation with lipophilicity; in vitro evaluation of antiproliferative activity toward five carcinoma cell lines and normal fetal lung cell line; molecular behavior study on target estrogen receptors by molecular docking and correlation of antiproliferative activity toward ER+ breast carcinoma cell lines and in silico estrogen receptor affinity binding. Retention behavior of 11 newly synthesized succinimide derivatives was determined by reversed phase high performance thin layer chromatography (RP HPTLC) with the application of two-component mixtures water - organic solvent (methanol, acetonitrile or acetone) with adequate volume fractions of the organic modifier. After chromatographic development RM0 and S parameters were calculated. The logarithm of partition coefficient, logP for the analyzed compounds were calculated by different softwares. Physico-chemical properties, pharmacokinetic and toxicological parameters, aquatic toxicity and relative affinity to estrogen receptors were predicted in silico. The affinity toward 4 types of receptors (G-proteine coupled receptors, ion channels, kinase inhibitors, nuclear receptors) were calculated as well. Standard MTT assay was applied to evaluate cytotoxic activities of the analyzed succinimides after cells were exposed. Antiproliferative activity were investigated toward commercial MRC-5, A549, HeLa, MDA-MB-231, MCF-7, HT-29 cell lines and IC50 values were calculated for each compound. MolDock Score that represents energy of binding to estrogen alfa and estrogen beta receptors was determined by molecular docking. Statistically significant linear correlations were determined between the chromatographic retention constants (RM0 and S) and calculated logP, and the best two were obtained in correlation of retention constants with MlogP and ClogP. The examination of RM0 and S influence on pharmacokinetics indicated parabolic dependence of the absorption constant (Ka) and plasma protein binding predictor (PPB) from the observed constants while the volume of distribution (Vd) and the ability to cross the brain blood barrier (logBBB) had linear association with the retention parameters. The toxicity of the analysed compounds evaluated in silico as LD50 on rodents was lower in comparison with the drugs with succinimide structure that are on the market and had parabolic correlation with the RM0 and S values. The experiments indicated that none of the compounds examined had cytotoxic activity toward the healthy lung fibroblast cells. The results of the in vitro assay shown that none of the investigated compounds demonstrated antiproliferative activity toward fetal lung cells. The most potent antiproliferative agents were compounds 6 and 7 toward MCF-7 cell line, and compound 11 toward A549 cell line. Molecular docking shown lower energy for binding to ERA in comparison to ERB.

Full textAbstract:
Participatory Sensing (PS) systems rely on the willingness of mobile users to participate in the collection and reporting of data using a variety of sensors either embedded or integrated in their
cellular phones. Users agree to use their cellular phone resources to sense and transmit the data of interest because these data will be used to address a collective problem that otherwise would
be very difficult to assess and solve. However, this new data collection paradigm has not been very successful yet mainly because of the lack of incentives for participation and privacy concerns. Without adequate incentive and privacy guaranteeing mechanisms most users will not be willing to participate. This thesis concentrates on incentive mechanisms for user participation in PS system. Although several schemes have been proposed thus far, none has used location information and imposed budget and coverage constraints, which will make the scheme more realistic and efficient. A recurrent reverse auction incentive mechanism with a greedy algorithm that selects a representative subset of the users according to their location given a fixed budget is proposed. Compared to existing mechanisms, GIA (i.e., Greedy Incentive Algorithm) improves the area covered by more than 60 percent acquiring a more representative set of samples after every round, i.e., reduces the collection of unnecessary (redundant) data, while maintaining the same number of active users in the system and spending the same budget.

This master thesis covers re-engineering methods of legacy systems. Legacy system is an old system, which is hardly compliant with modern technologies and used only because it has become an integral part of organization business process support during the long period of its maintenance. These systems are large, monolithic and difficult to modify, and cost and risk of their replacement are difficult to predict. The science of software engineering offers an incremental modernization of information systems applying the re-engineering of legacy software. The main goal of software re-engineering is to transform the software in the way, it would become easier to understand, maintain and re-use, at the same time preserving its useful, time trusted functions. The main re-engineering methods are source code translation, reverse engineering and data re-engineering. This thesis covers the analysis of these methods, which was made during the re-engineering of wood production and sales accounting system. The adoption and realization time rate of every method was examined. The influence of the applied re-engineering methods to the system reliability, efficiency, usability and other quality metrics is given.

A ce jour, les thérapies anti-obésité restent limitées. De récente études ont fourni des résultats prometteurs en démontrant une diminution du poids de la souris via une injection stéréotaxique d’une forme dominante négative de l’AMPK (AMPK DN) directement dans le noyau ventromédial hypothalamique (VMH). Cependant, le potentiel thérapeutique de cette thérapie génique se voit entravé par une libération non spécifique de l’AMPK suite à une injection intraveineuse, plus adaptée à une approche clinique. Nous avons donc développé une approche de « nanobiomédecine » en utilisant des exosomes - nanovésicules contenant des lipides, des protéines et des acides nucléiques - pour délivrer l’AMPK DN spécifiquement au niveau du VMH. Des cellules dendritiques immatures ont été utilisées pour produire des exosomes non-inflammatoires. Pour permettre le ciblage spécifique du VMH par les exosomes, les cellules dendritiques ont été transfectées pour exprimer Lamp2b, une protéine exosomale, fusionnée au peptide de ciblage neuronal RVG. De façon intéressante, les exosomes Lamp2b-RVG ont été localisés au niveau du cerveau suite à une injection intraveineuse. Les exosomes Lamp2b-RVG ont ensuite été chargés par l’AMPK DN sous le contrôle d’un promoteur spécifique du VMH, apportant une double spéficité tissulaire aux exosomes. Les exosomes Lamp2b-RVG chargés avec l’AMPK DN induisaient une diminution de la phosphorylation de l’acetyl-CoA carboxylase dans des cellules Neu2A in vitro. De plus, l’injection intraveineuse d’exosomes Lamp2b-RVG chargés avec l’AMPK DN induisait une perte de poids de l’animal après 6 jours de traitement, démontrant le potentiel de cette approche de « nanobiomédecine »Actual pharmacological therapies for treating obesity are limited. Promising results on decreasing mice body weight were obtained using a ventromedial nucleus hypothalamic (VMH) stereotaxic injection of a dominant negative isoform of AMPK (AMPK DN). However, DNA-mediated therapeutic potential is hampered by inadequate tissue specific delivery following a systemic injection - more adapted to a bedside approach -. Herein, we developed a nanobiomedicine approach using exosomes - nano-scaled endogenous vesicles containing lipids, proteins and nucleic acids - to deliver DNA in a hypothalamic specific way. Immature dendritic cells were used to generate non inflammatory exosomes. Exosome neuronal targeting aptitudes were achieved by constraining the dendritic cells to express Lamp2b, an exosomal protein, fused to the neuron-specific RVG peptide. Interestingly, DID-labelled Lamp2b-RVG exosomes were found into the mice brain following an intravenous injection. Isolated Lamp2b-RVG exosomes were then loaded by transfection-mediated techniques with AMPK DN under the control of a VMH specific promoter conferring double tissue expression specificity to the exosomes. AMPK DN-loaded exosomes induced a decrease of acetyl-CoA carboxylase phosphorylation in Neu2a neuronal cells in vitro. Furthermore, intravenously injected AMPK DN loaded exosomes induced a decrease of mice body weight following 6 days of treatment, demonstrating the potential of this nanobiomedicine approach

Submitted in fulfillment of the requirements for the degree of Master of Management Sciences: Business Administration, Durban University of Technology, Durban, South Africa, 2017.This qualitative study explored alternative revenue sources within and outside PBS radio stations that can be utilised to improve revenue generation at South African Broadcasting Corporation (SABC) Public Broadcasting Radio Stations (PBS). PBS radio relies heavily on traditional advertising revenue, sponsorships and TV licence fees, revenue sources are insufficient to sustain public broadcasting radio service in South Africa because funding from the South African Government is limited to specific projects. Public broadcasting radio services in South Africa have to provide content of public value while remaining competitive and profitable. The SABC is the sole owner of fifteen public broadcasting radio stations, making it one of the dominant media owners in South Africa. SABC owns all public broadcasting radio stations and has the highest audience penetration in South Africa which should translate into receiving the highest revenue share. However, this is not the case. Commercial radio stations earn a bigger percentage of the pie of advertising revenue although PBS radio stations command higher audience penetration. Semi-structured interviews were conducted with fifteen public broadcasting radio station managers and three senior public broadcasting managers to ascertain what alternative sources within and outside the radio station can help improve the revenue of the radio stations. The analysis of the data collected through interviews identified that there are a number of alternative sources which can assist in improving the revenue of the radio stations. It is therefore time that PBS Radio stations monetise their audience and not rely heavily on traditional advertising revenue. Six important alternative revenue sources are identified as follows: • Radio station events and outside broadcasts: Revenue generation potential is immense with opportunities for gate-takings, sponsorship and advertising or promotional revenues. • Broadcast syndication and sale of content: Original programming content and popular music genre playlists are sought after by the public or other entities that are prepared to pay for the content. • Radio Station Websites: Opportunities to generate revenue by marketing website opportunities to the public and advertisers. • Merchandising: Radio audiences like to own radio station branded merchandising like t-shirts, caps and jackets which can be made available at radio stations and retail stores for the public to purchase. • Cellular or mobile phones: Mobile phones provide an interactive element to radio campaign advertisements, competitions, and promotions, which should be monetised as an extension to advertisers‟ radio campaigns. • Social Media Platforms: Radio campaigns are extended to social media platforms like Facebook, LinkedIn, Instagram, Pinterest and Twitter to target a larger audience.

Submitted in fulfilment of Masters in Development Planning, Faculty of Engineering & the Built Environment, School of Architecture and Planning, University of the Witwatersrand, 2016The purpose of the thesis is to assess municipal own sources of revenue in the Johannesburg Metropolitan Municipality. Section 229 of the Constitution of South Africa states that municipalities may impose rates on property and surcharges on fees for services provided by the municipality or on behalf of the municipality. The primary data obtained from the City of Johannesburg facilitated the assessment of property tax and user fees revenue performance of the municipality as well as the challenges in the administration of revenue. A case study approach was used and the data required was on assessment of property tax and user fees revenue performance of the municipality as well as the challenges in the administration of revenue. Data was therefore collected from the primary data sources.This research shed the light on challenges that the City of Johannesburg Metropolitan Municipality encounter in the process of tax rate and charges administration in order to raise enough revenue to cover the cost of service delivery. Findings in relation to revenue collection were based on the information obtained from a user’s survey, the department of revenue, head of property unit, MMC finance and the executive mayor. Amongst other challenges that affect the CoJ own source of revenue, is the issue of property valuation and billing system which is to allow the city to charges tax payers according to property market value. In addition, there is no proper line of communication between the city and the community about the necessity of property tax rates and fee charges. Hence, some members of local community are not fulfilling their property tax obligations because of poverty or by preference. Observations from the study indicates that practical difficulties related to tax base identification and the lack of human capacity contribute significantly to the underperformance of the property tax administration system across South Africa as a whole. The inadequate records on property information have contributed to the inefficiency of the property tax system since many taxable units are not known, and therefore, it becomes difficult for the taxing authorities to collect property tax. Consequently, the City of Johannesburg Metropolitan Municipality is unable to collect enough revenue to cover the cost of service delivery. In order to rectify these problems some of the measures recommended include the need to improve human capacity and the communication/collaboration between local community and the municipality.

The primary purpose of this study was to investigate the effects of the elimination
of the Indiana public school general fund property tax on student cash transfer school
board policy. As a result of the data collected for this study, it includes an analysis for
the general fund financial trends of all 292 Indiana public school corporations, as well as
trends regarding other data such as; Average Daily Membership (ADM), General Fund

The following recommendations are made; (1) Any Indiana public school
corporation currently not allowing student cash transfers per board policy should change
the policy to begin allowing such transfers, (2) The Indiana Association of Public School
Superintendents (IAPSS) should adopt guidelines for ethical behavior regarding student
cash transfers, specifically as it pertains to advertising, for member superintendents to
follow, (3) Small school corporations, particularly those with an ADM of less than 1,000
students, should begin partnering with other small school corporations to coordinate
administrative service and instructional services, and (4) Indiana public school

Well established financial basis is fundamental to the development of local communities. However, because of the various restrictions of the governmental tax revenue distribution system, there are discrepancies of tax revenue distribution among local communities. Consequently, the autonomic power and general administrative operations of local governments were jeopardized. How to establish a sound revenue system to let the local governments develop their own self-sufficient tax revenue sources and establish sound financial foundation is the key of local community development. After the implementation of the General Regulation of Local Government Taxation, only counties of Taoyung, Maioli, Kaohsiung, and Tucheng City of Taipei County started levy their own devised taxes. Therefore, it is interesting and necessary to investigate about what the problems are. Are there better solutions? What the local governments and people should do? During the past, studies were mostly concentrated on the opinions of local government taxation officials and members of the council and never paid attentions to the people who pay the taxes. Therefore, this paper attempts to investigate through the implementation of the General Regulation of Local Government Taxation and find out what the attitudes of Taoyung government and construction industries are toward local devised tax revenue sources. The results of this study, hopefully, will provide some suggestions for other local governments.
