Abstract:

The aim of the present study was to evaluate the relationship between AOPP (Advanced oxidation protein products) and bovine neutrophils 'in vitro'. For this purpose AOPP were produced "in vitro" by oxidizing bovine serum albumin with HOCl (hypochlorous acid) and bovine neutrophils were isolated from whole blood of dairy cattles. AOPP-BSA were incubated with freshly isolated bovine neutrophils, unstimulated and stimulated with PMA a strong activator of the respiratory burst. Neutrophils ROS production and viability were measured by luminol-amplified chemiluminescence and by MTT and lactate dehydrogenase assays (LDH), respectively. Results obtained have shown that AOPP-BSA are able to reduce significantly ROS production of PMA stimulated neutrophil and their viability measured by MTT assay, no cell lysis was detected by LDH assay. On the basis of these results, our work has studied if AOPP are able to trigger apoptotic events. For this purpose, caspase 8-9-3 and DNA laddering were used as markers in order to discriminate between the 'intrinsic' and the 'extrinsic' pathway of apoptosis. The results obtained showed that un-stimulated bovine neutrophils incubated with AOPP-BSA show a higher but not significant production of active caspase 8 in comparison with the incubation with BSA. Also caspase 3 display an increase, but not significant, in un-stimulated neutrophils after 6 hours of incubation with AOPP-BSA, respects the incubation with BSA. No differences were obtained for caspase 9 and for DNA laddering. Therefore, in these experimental conditions is possible to conclude that the 'intrinsic' pathway of apoptosis was not involved in the reduced functionality of neutrophils or in their reduced viability, but bovine neutrophils incubated with AOPP-BSA seem to be "accompanied" to the early phases of the 'extrinsic' pathways of apoptosis. In addition, the present work wanted to evaluate the capacity of triggered neutrophils to generate AOPP in vitro. BSA was incubated with un-stimulated and PMA-stimulated bovine neutrophils for 1-2-3 hours and the production of specific markers of protein oxidation such as AOPP, dityrosines and carbonyls was assessed. BSA incubated with stimulated neutrophils presents a significant higher level of AOPP and dityrosines respects the incubation with un-stimulated neutrophils. Carbonyls don't seem to be produced in these condition, at least at the beginning of the incubation. In parallel, BSA incubated with the same concentration of HOCl produced by PMA-stimulated neutrophils, for 1-2-3 hours, presents a higher level of AOPP, dityrosines and carbonyls. Therefore, it's possible to conclude that bovine neutrophils are able to oxidize BSA in vitro and generate chemical and structural modification such as AOPP and dityrosines, in the experimental condition used. However, carbonyls seem to be a non-specific indicator of neutrophils-mediated protein oxidation. The direct exposure of BSA to HOCl couldn't fully mimic the complex events leading to BSA oxidation and AOPP production by activated neutrophils. Lo scopo del presente studio è stato quello di valutare le relazioni tra AOPP (prodotti avanzati di ossidazione proteica) e i neutrofili di bovino "in vitro". A questo scopo le AOPP sono state generate "in vitro", ossidando l'albumina sierica bovina con HOCl (acido ipocloroso) mentre i neutrofili di bovino sono stati isolati da sangue intero di bovine da latte. Le AOPP-BSA sono state incubate con i neutrofili di bovino appena isolati in condizioni di assenza di stimolo o stimolati con PMA un forte attivatore del "burst" respiratorio. La produzione di ROS da parte dei neutrofili e la loro vitalità , sono state misurate rispettivamente mediante chemiluminescenza amplificata dal luminolo e dai saggi MTT e lattato deidrogenasi (LDH). I risultati ottenuti hanno mostrato che le AOPP-BSA sono in grado di ridurre significativamente la produzione di ROS da parte dei neutrofili stimolati con PMA e la loro vitalità , misurata con il saggio MTT mentre non è stata rilevata lisi cellulare mediante saggio LDH. Sulla base di questi risultati il presente lavoro si è proposto di studiare se le AOPP sono in grado di scatenare eventi apopotici. A questo scopo le caspasi 3, 8 , 9 e la frammentazione del DNA sono stati utilizzati come marker con l'obiettivo di discriminare tra la via intrinseca e quella estrinseca di apoptosi. I risultati ottenuti hanno mostrato che i neutrofili di bovino non stimolati e incubati con AOPP-BSA per 1 ora e 6 ore, presentano una maggiore ma non significativa produzione di caspasi 8 attiva, se comparati con l'incubazione con BSA. Anche la caspasi 3 mosta un incremento, non significativo in neutrofili non stimolati incubati con AOPP-BSA per 6 ore, rispetto all'incubazione con BSA. Non è stata ottenuta alcuna differenza per quanto riguarda la caspasi 9 e la frammentazione del DNA. Tuttavia, in queste condizioni sperimentali è possibile concludere che la via intrinseca dell'apoptosi non è coinvolta nella riduszione della funzionalità dei neutrofili di bovino o nella loro vitalità ma i neutrofili di bovino incubati con AOPP-BSA sembrano piuttosto essere 'accompagnati' verso le fasi precoci della via estrinseca dell'apoptosi. Inoltre, il seguente studio ha voluto valutare la capacità dei neutrofili di bovino attivati di generare AOPP 'in vitro'. La BSA è stata incubata con neutrofili di bovino non stimolati e stimolati con PMA per 1-2-3 ore, ed è stata misurata la formazione di specifici marcatori di ossidazione proteica come le AOPP le ditirosine e i carbonili. La BSA incubata con neutrofili stimolati con PMA, presenta un livello significativamente alto di AOPP e ditirosine rispetto all'incubazione con neutrofili non stimolati. I carbonili invece sembrano non essere prodotti in queste condizioni, almeno nelle fasi inziali dell'incubazione. In parallelo, la BSA incubata con la stessa concentrazione di HOCl prodotta dai neutrofili stimolati, per 1-2-3 ore, presenta livelli più elevato di AOPP, ditirosine e carbonili. Tuttavia è possibile concludere che i neutrofili di bovino sono in grado di ossidare la BSA e generare modificazioni chimiche e strutturali come AOPP e ditirosine nelle condizioni sperimentate. I carbonili invece sembrano non essere un marcatore specifico di ossidazione proteica mediata dai neutrofili. In aggiunta la diretta esposizione della BSA all'HOCl non è in grado di mimare completamente la complessità degli eventi che portano all'ossidazione della BSA e alla produzione di AOPP da parte dei neutrofili attivati.

Abstract:

Most aspect-oriented programming technology used today uses a linguistic approach that enables programmers to write modular crosscutting code. Two limitations of these approaches are that there is only one decomposition present for a code-base and that they require developers to adopt a new (or extended) programming language. We propose fluid AOP to modularize crosscutting concerns without these limitations. Fluid AOP provides mechanisms in the IDE for creating constructs that localize a software developer's interaction for a specific task. These constructs act as fluid aspects of the system. They are editable representations of the subset of the code-base that the developer needs to interact with to perform a task. We present three fluid AOP prototypes and provide comparisons between them; as well as comparisons between the fluid AOP, linguistic AOP, and non AOP approaches.

Abstract:

This diploma thesis is focused on the study of the influence of advanced oxidation processes on degradation of organic dyes. The field of AOP – very effective physically-chemical methods of wastewater treatment – includes application of strong oxidation agents, UV and ionizing radiation and electrical discharges. For this thesis, two of these methods were chosen – the application of oxidation agent (ozone) and UV radiation. Along with electrolysis, which is mentioned rather marginally in this thesis (it is the subject of the previous thesis), these phenomena are products of electrical discharge in water, where they participate in the processes of degradation in a different way. For all measurement series, two direct azo dyes were chosen as model substances – C.I. Direct Blue 106 and C.I. Direct Red 79. The ozonizer, in which either oxygen or synthetic or technical air were loaded as carrier gases, was used for degradation of dyes by ozone. The generated ozone was loaded into the bubbling vessel with dye solution of different initial concentration (10–130 mg.dm-3), which was followed by other bubbling vessel with KI solution for the next analytical determination of the amount of generated ozone. The other parameters changed were the gas flow (1–2 dm3.min-1), ozonizer output (minimal and maximal), type of dye, pH value of the solution (neutral or acid) and additional electrolyte (NaCl, Na2SO4 or any). The reactor for the study of the influence of UV radiation on degradation of dyes was an UV sterilizer into which the equivalent volume of dye solution was added. The possibilities of experimental settings were limited and only the type of dye, an additional electrolyte and pH value of the dye solution were adjusted (as in the case of ozone). Several series of samples were measured with various input conditions which more or less influenced the degradation of investigated dyes in this experiment. It was found that for both used methods the Direct Blue 106 dye was more degradable (with significantly better results for ozone than for UV radiation). The degradation of Direct Red 79 dye proceeded only by ozone treatment, in the case of the application of UV radiation no degradation occurred. By investigation of the influence of initial concentration of dye on its degradation, it was confirmed that with the initial concentration enhancement the final concentration rises as well, whereas in low concentrations (10–50 mg.dm-3) the initial concentration has no effect. The addition of an electrolyte had an accelerating effect on dye degradation in both methods (NaCl and also Na2SO4 showed similar results though the degradation proceeded in different ways). The addition of HCl accelerated the degradation only in the case of UV radiation; during the application of ozone the pH level of the system did not have any influence on the degradation. Oxygen and synthetic air had the strongest effect on ozone degradation (comparable results); in the case of technical air the final dye concentration was higher up to 30 %. The gas flow of 1.5 dm3.min-1 was stated as optimal with the ozonizer output 30 W (maximal). At minimal power the ozonizer produced very low amount of ozone.

La nostra arquitectura middleware es divideix en dues capes: un model de composició i una plataforma escalable de desplegament d'aspectes distribuïts. Per últim, es demostra la viabilitat i aplicabilitat del nostre model mitjançant la implementació i experimentació de prototipus en xarxes de gran escala reals. In this PhD dissertation we present a distributed middleware proposal for large-scale application development. Our main aim is to separate the distributed concerns of these applications, like replication, which can be integrated independently and transparently. Our approach is based on the implementation of these concerns using the paradigm of distributed aspects. In addition, our proposal benefits from the peer-to-peer (P2P) networks and aspect-oriented programming (AOP) substrates to provide these concerns in a decentralized, decoupled, efficient, and transparent way. Our middleware architecture is divided into two layers: a composition model and a scalable deployment platform for distributed aspects. Finally, we demonstrate the viability and applicability of our model via implementation and experimentation of prototypes in real large-scale networks.

Abstract:

O paradigma de orientação a aspectos é utilizado em vários frameworks e aplicações com o objetivo de melhorar a modularidade e a separação de interesses. Contudo, a combinação do paradigma de orientação a aspectos com mecanismos de captura de exceção pode elevar o número de cenários sujeitos a falhas. Pois, os elementos que compõem os aspectos podem levantar exceções, as quais a aplicação não foi projetada para tratá-las. Nesta dissertação é apresentado (i) um estudo empírico mostrando como a programação orientada a aspectos afeta o tratamento de exceção de uma aplicação que utiliza o JBoss AOP como implementação do paradigma de orientação a aspectos; e (ii) uma ferramenta que deu suporte ao estudo. O estudo mostra que ocorrem falhas no tratamento de exceção principalmente porque as exceções são capturadas por subsunção. Aspect Oriented Paradigm (AOP) is used in many frameworks and applications in order to improve the modularity and separation of concerns. However, the combination of AOP and exception handling mechanisms may increase the number of error-prone scenarios. AOP may raise exceptions which the application was not designed to handle it. This dissertation presents (i) an empirical study showing how the AOP affects exception handling in an application that uses JBoss AOP to implement AOP, and (ii) a support tool for the study. The study shows that error-prone scenarios occur mainly because exception handling exceptions are caught by subsumption.

Abstract:

ITC/USA 2015 Conference Proceedings / The Fifty-First Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2015 / Bally's Hotel & Convention Center, Las Vegas, NV Global Positioning System (GPS) interference signals are suppressed using angle-of-arrival (AOA) techniques, while at the same time the power of the GPS signal is enhanced. After estimating all AOAs from the received signal, we must determine which AOA corresponds to the GPS signal of interest, and in the presence of high-power interference signals. In this paper, we describe an algorithm for selecting the GPS AOA by first comparing all AOAs derived from the received signals before despreading. Although this approach has excellent performance, it has a high computational complexity. In order to overcome this drawback, we introduce a modification that yields an efficient GPS AOA estimation algorithm, which is based on a modified despreader and the constant modulus (CM) array cost function. The CM array is capable of selecting signals that have a constant modulus while rejecting non-CM interference signals. The modified despreader is the mechanism that allows this to be achieved, where unlike the interference signals, the GPS signal of interest maintains a constant modulus.

Abstract:

Il problema della contaminazione dei terreni e delle acque di falda da composti organici biorecalcitranti sta diventando sempre più preoccupante agli occhi della comunità scientifica e dell’opinione pubblica. L’aumento del numero di siti contaminati da tali sostanze sta spingendo alla graduale sostituzione delle tradizionali operazioni di smaltimento in discarica con tecnologie che consentano la bonifica attraverso la riduzione del carico inquinante fino al raggiungimento di concentrazioni residue non pericolose per la salute umana. Tra i possibili processi alternativi, i processi avanzati di ossidazione chimica (AOP) possono costituire una potenziale soluzione a molti casi di contaminazione da composti organici. Se opportunamente progettati, tali sistemi possono condurre alla completa mineralizzazione degli inquinanti o, eventualmente, alla loro trasformazione in molecole più facilmente biodegradabili. Il loro principio operativo è basato sull’ idea di generare un pool di specie ossidanti altamente reattive. I diversi AOP si differenziano solo nel modo in cui tale pool di sostanze viene generato. Una volta prodotte, tali specie sono in grado di reagire efficacemente con i principali inquinanti di interesse ambientale. Inoltre, alcuni AOP sono in grado di trattare efficacemente anche composti adsorbiti sulla superficie del suolo, in quanto le specie radicaliche ne favoriscono il desorbimento rendendole disponibili all’ossidazione in fase acquosa. Le caratteristiche degli AOP li rendono perfettamente idonei come tecnologia di bonifica in-situ. In questa configurazione, si prevede l’iniezione nel sottosuolo della soluzione ossidante senza la necessità di rimuovere il terreno e di estrarre le acque di falda. Il presente studio è stato sviluppato con l’intento di perseguire un duplice obiettivo: da un lato approfondire le conoscenze di base sui meccanismi di azione degli AOP, al fine di sviluppare criteri di progettazione innovativi; dall’altro valutare l’applicabilità di diversi processi AOP a situazioni rappresentative dei siti contaminati tipicamente riscontrati in Italia. Il primo obiettivo è stato perseguito mediante uno studio di base finalizzato ad identificare la relazione tra condizioni operative del processo e formazione di specie radicaliche e non, nei sistemi di ossidazione basati sul reattivo di Fenton, sul processo a persolfato attivato e sul processo di ossidazione basato sugli acidi perossi-organici (perossiacidi). Il secondo obiettivo è stato invece perseguito sviluppando un approccio progettuale incentrato sulla redazione di studi di fattibilità. Tale approccio ha consentito di arrivare, nel caso del processo Fenton, fino alla realizzazione di un intervento di ossidazione chimica in-situ (ISCO) in scala pilota per la bonifica di un sito contaminato da MtBE, mentre nel caso del sistema a persolfato attivato e dei perossiacidi si è limitato alla fase di studio di fattibilità in scala di laboratorio. La progettazione delle diverse fasi sperimentali é stata, ove possibile, effettuata utilizzando il metodo Rotatable Central Composite (RCC), mentre i risultati ottenuti sono stati interpolati mediante opportuni strumenti statistici, come il Metodo delle Superfici di Risposta (RSM) al fine di individuare le relazioni quantitative tra le prestazioni dei processi investigati e le condizioni operative impiegate. La presente tesi è stata scritta dedicando ad ogni tecnologia presa in esame una prima parte bibliografica, nella quale la tecnologia viene introdotta e ne vengono messe in evidenza le caratteristiche, seguita da una seconda parte in Appendice, dove i risultati sperimentali ottenuti vengono mostrati e discussi attraverso una selezione delle pubblicazioni prodotte durante il triennio di svolgimento del dottorato di ricerca, compreso tra il 2004 ed il 2007, e sottomesse a riviste specializzate del settore o presentate nell’ambito di convegni internazionali. The contamination of soil and groundwater by means of bio-recalcitrant organic compounds, is becoming a matter of concern for scientific community and public opinion. The increase of the number of contaminated sites, is forcing to gradually switch from traditional dump disposal, towards innovative technologies which are capable of reaching the remediation goals, thus reducing the pollutant load to concentrations which are considered harmless for human health. Among the innovative ones, Advanced Oxidation Processes (AOPs) could represent a potential solution to be applied for remediating contamination by bio-recalcitrant organic compounds. Their operative principle is based upon the idea of generating a pool of highly-oxidative species. The AOPs differ only by the way in which this pool is generated. Once formed, these species are capable to effectively react with most of common pollutants such as hydrocarbons, chlorinated solvents, polycyclic aromatic hydrocarbons and polychlorobiphenyls until their complete oxidation to carbon dioxide and water, or at worst their transformation to more bio-degradable products. Moreover, some AOPs are able to effectively tackle sorbed compounds, since oxidative radicals can desorb these compounds from the soil surface, thus allowing their oxidation in aqueous phase. Besides, it is worth pointing out that the AOPs characteristics make them suitable to be applied as in-situ remediation technologies. In this configuration, the oxidant is injected directly into the subsurface without the need of soil excavation or groundwater extraction. The present study has been developed with the intention of achieving a two-fold objective: on the one hand, to better understand the fundamental mechanisms of AOPs, in order to develop innovative criteria for their design; on the other hand, to assess the feasibility of different AOPs to those situations which are somehow representative of the Italian contaminated sites. The first objective was pursued by developing a fundamental study aimed to identify the relationship between the process operating conditions and the formation of radical and non-radical species for Fenton’s process, activated persulfate and peroxy-acid oxidation processes. The second objective was instead pursued by developing, based on the experimental results of the fundamental study, a design approach based on the execution of feasibility studies. In case of Fenton’s process, a pilot-scale In-Situ Chemical Oxidation (ISCO) treatment for the remediation of an MtBE-contaminated site was developed, whereas in the case of activated persulfate and peroxy-acid oxidation technologies a lab-scale feasibility test was carried out. The design of the different experimental phases was performed, as much as possible, by applying the Rotatable Central Composite method (RCC), whereas the relationships between process performance and applied operating conditions was found by handling and interpolating the experimental results by proper statistical tools based on the Response Surface Method (RSM). In this Ph.D. thesis, each tested AOP is first discussed in a bibliographic part, where the process is introduced and its main features are explained, based on the available and updated literature. The main findings obtained in this part and the innovation introduced with respect to the state of the art is also described in this section of the Ph.D. thesis. The details of these results are shown in the second section of the thesis, which consists of four Appendices, where a selection of papers submitted either to international conferences and peer-reviewed journals during my Ph.D. research are included.

Abstract:

Generally, a ground telemetry station for launch vehicle (LV) has tracking function only; therefore, position measurements depend on radar. Time of arrival (TOA) and angle of arrival (AOA) are typical location techniques for emitting targets. In this paper, we propose a Combined TOA and AOA localization method for LV using two ground stations. When transmitter (Tx) time is not known, it is necessary to make virtual onboard timer for TOA estimation. The virtual onboard timer generates time stamps of streaming frame according to data rate. First station which is located in space center has no tracking function. But it can generate the virtual onboard timer. Second station has tracking function, so it generates AOA information. By solving sphere equation(s) of TOA from at least one station and a line equation of AOA, target position in three-dimensions (3D) can be obtained. We confirm the localization performance by means of comparison with an on-board GPS of a real launch mission.

Full text

Abstract:

To specify its intention clearly, a pointcut definition must specify the join point where to adapt a crosscutting functionality and the applicability condition of the crosscutting functionality (if any), and to realise modular abstraction of a crosscutting functionality an advice must abstract only the crosscutting functionality. A state-dependent crosscutting concern is an aspect whose applicability of its advice at a matched join point is statedependent, and call graph-based AOP approaches are insufficient for a state-dependent crosscutting concern because they do not allow specification of the state-dependent applicability condition in the pointcut definition. Event-based AOP approaches expose sequences of event executions as join points. Therefore, the state-dependent applicability condition of an aspect's advice can be specified in a pointcut definition by stating the sequence of event executions that brings the base program into the state when the advice is applicable. However, this means the programmer must know the sequence of event executions that brings the base program into the state. This thesis proposes a state-based AOP approach that exposes state and state transition join points that allow a state-dependent applicability condition to be clearly specified in the pointcut definition simply by specifying the state or the state transition when the advice is applicable, as implemented in the proof-of-concepts prototype language, TinyState.

Abstract:

This thesis develops a method for combining AOP and HLA, leveraging the separation-of-concerns approach used by AOP to allow the creation of core models, free from simulation distribution semantics. Through the use of automated tools, these models are then woven with a generic-HLA aspect, producing an HLA-enabled simulation component. Using AOP in this manner removes the need for model developers to have an in-depth understanding of the HLA, helping to remove the prime factor restricitng a broader uptake of distributed simulation technologies: development complexity.

Abstract:

Wastewater is the main source of micropollutants and although treated in urban wastewater treatment plants (WWTPs), it can continue to contain recalcitrant substances, potentially dangerous for the health of living organisms and for the environment.It is therefore necessary to implement appropriate actions to limit its diffusion. Advanced oxidation processes (AOPs), which use hydroxyl radicals for the remediation of organic contaminants in wastewater, are highly effective innovative methods to accelerate the remediation process. AOPs can amplify their action if combined with ozone (O3) and if subjected to mono and polychromatic irradiation. The main objective of the PhD thesis was precisely to apply heterogeneous and homogeneous photolysis and photocatalysis systems in the liquid phase, for the removal of levofloxacin (LFX), a widely used antibiotic belonging to the quinolone family. Comparison of degradation kinetics, chromatographic detection of degradation products and evaluation of toxicity were some of the steps of the work. In detail, this thesis consists of six chapters. Chapter 1 provides an accurate bibliographic analysis, with the aim of giving an overview of the numerous fields of investigation connected with the topic of this thesis: a description of wastewater characteristics and of the Italian legislative decree 152/06 which regulates discharges into the environment, the organization of wastewater treatment plants, the problem of emerging contaminants, including antibiotics and in particular the class of fluoroquinolones, taken into consideration as case study of this thesis, the advanced oxidation processes (AOPs), and, finally, a brief review on the toxicity tests used in this work. Chapter 2 contains the first experiment of this thesis, which consists in the degradation of levofloxacin in distilled water, through the processes of photolysis and heterogeneous photocatalysis with titanium dioxide (TiO2). The first purpose of this chapter was to evaluate the efficiency of heterogeneous photocatalysis with TiO2, a process that in the literature is taken as a "reference" model, a very effective technique. Experimental results obtained demonstrate that this process is effective to remove levofloxacin and its by-products in almost 4 hours, and seems to follow a second-order kinetic. However, this process cannot be applied on a large scale due to of the high costs of treatment for the recovery and separation of the photocatalyst from the solution. Chapter 3 provides an evaluation of the efficiency of TiO2 as photocatalyst immobilized on the surface of a borosilicate tube for the degradation of levofloxacin through a "continuous" irradiation system, different from the "static" system used in chapter 2. In particular, not only a kinetic study was carried out, but also some toxicity tests, including the Vibrio fischeri bioluminescence inhibition test and the phytotoxicity tests on Lepidium sativum and Solanum lycopersicum, in order to better understand the potential applicability of this system. More specifically, in the case of phytotoxicity tests, the last sample of each photodegradation test carried out with the "continuous" system (with and without the TiO2-coated tube) was tested; in the case of the Vibrio fischeri assays, the most representative samples were tested, i.e. those that seemed to present the greatest number of transformation products, on the basis of the chromatograms obtained by liquid chromatography analysis. From experimental results, both photolysis and photocatalysis follow a very similar trend and degradations seem to be modelled with a first-order kinetic. The toxicity tests on Vibrio fischeri showed a low toxicity of the starting solution containing only levofloxacin. All the solutions subjected to photolysis were found to be toxic, while the solutions subjected to photocatalysis highly toxic. This unexpected result has been attributed to the probable detachment of titanium dioxide nanoparticles from the surface of the tube, whose toxicity is also being confirmed by the European Food Safety Authority (EFSA). Phytotoxicity tests confirmed these results showing an inhibition of seed germination, root elongation and growth index in both the plants tested. Chapter 4 is reported in this thesis as an under review article submitted to “Environmental Science and Pollution Research (ESPR)”. In this scientific work, levofloxacin solution was treated using hydrogen peroxide (H2O2), peroxymonosulfate (PMS) and peroxidisulfate (PDS), as oxidizing agents, which respectively provide only OH• radicals, both OH•/SO4•– radical, and SO4•– radicals. The efficiency of the three oxidizing agents was tested in different pH conditions, and the most efficient treatment (simulated radiation/PDS) was applied (and optimized) to remove levofloxacin from a simulated wastewater (SWW). In this case the main transformation products (TPs) were identified by liquid chromatography coupled with mass spectrometry, the degradation pathway was suggested and toxicity tests on Escherichia coli (LMG2092), a Gram-negative bacterium, and Micrococcus flavus (DSM1790), a Gram-positive bacterium, were performed. Experimental results demonstrated that simulated irradiation/H2O2 treatment showed less impact on LFX reduction than the combined AOPs of simulated irradiation/PMS and simulated irradiation/PDS. In contrast, PMS and PDS were able to degrade levofloxacin completely. In particular, the PMS resulted the best in phosphate buffer because it has been able to completely transform LFX into LFX N-oxide in 30 seconds, through a non-radicals mechanism. However, except for phosphate buffer, simulated irradiation/PDS system showed the best performance achieving a complete degradation of LFX after 10 minutes of irradiation in all mediums investigated. This system was successfully applied in simulated wastewater (SWW) by using three different concentrations of PDS to optimize the process, and in all cases the degradation followed a first-order kinetic. Selected samples obtained from the photocatalytic treatment of LFX in SWW with the highest concentration tested of PDS were tested on Escherichia coli and Micrococcus flavus. Both the cultures of Gram-positive and Gram-negative bacteria were not affected after the effective degradation of levofloxacin by the sulphate radical based AOP. Chapter 5 provides a further insight into the potential eco-friendliness of sulphate radicals treatment for the degradation of levofloxacin. In particular, some of the samples obtained from the treatment of levofloxacin with peroxidisulfate in distilled water were subjected to the MTT (3- (4,5-dimethylthiazol-2-yl) -2,5-diphenyltetrazolium) bioassay on human epithelial-like lung cancer cell line A549. These experimental tests were carried out in Greece, at the University of Ioannina. Experimental results demonstrated that there was no toxicity effect on the cells viability. Finally, chapter 6 provides a brief description of the internship period carried out at Hydros S.r.l. (Tito, Potenza). During this experience, I participated in the design of fumes and wastewater treatment systems, and in the optimization of the parameters of the biological process of nitrification/denitrification/oxidation present within a real wastewater treatment plant. In conclusion, I can say that this PhD thesis demonstrates that AOPs may be an alternatve eco-friendly treatment for the removal of contaminants from wastewater effluents. The experimental results tends to demonstrate that solar advanced oxidation processes has the potential to open new feasible remediation strategies for WWTPs effluent tertiary treatment before wastewater reuse in irrigation for instance. However, most investigations are done at lab-scale. For a practical view and commercial uses, much more work is necessary to switch from batch work to a large scale to find out the efficiency and ecotoxicity of the processes.

Abstract:

Aspect-oriented programming (AOP) is a programming paradigm to localize and modularize the concerns that tend to be tangled and scattered across traditional programming modules, like functions or classes. Such concerns are known as crosscutting concerns and aspect-oriented languages propose to encapsulate them in modules called aspects. Because each crosscutting concern implemented in an aspect is separated from the other concerns, AOP improves reusability, readability, and maintainability of code.While it improves separation of concerns, AOP suffers from well-known composition issues. Aspects developed in isolation may indeed interact with each other in ways that were not expected by the programmers and therefore lead to a program that does not meet its requirements. Without appropriate tools, undesired aspect interactions must be identified by reading code in order to gain global knowledge of the program and understand where and how aspects interact. Then, if the aspect language does not offer the needed support, these interactions must be resolved by invasively changing the code of the conflicting aspects to make them work together. Neither one of these solutions are acceptable since global knowledge as well as invasive and composition-specific modifications are exactly what separation of concerns seeks to avoid.In this dissertation we show that the existing approaches to compose aspects are not entirely satisfying either with respect to separation of concerns. These approaches either rely on global knowledge and invasive modifications, which is problematic, or lack genericity and/or expressivity, which means that code reading/code modification may still be required for the aspect interactions they cannot handle.To properly detect and resolve aspect interactions we propose a novel approach that is based on AOP itself. Since aspect composition is a concern that, by definition, crosscuts the aspects, it indeed makes sense to expect that a technique to improve the separation of crosscutting concerns such as AOP is well-suited for the task. The resulting mechanism is based on reflection principles and is called reflective AOP. The main difference between "regular" AOP and reflective AOP lies in the parts of the system they address. While traditional AOP aims at modularizing the concerns that crosscut the base system, reflective AOP offers the possibility to handle the concerns that crosscut the aspects themselves. This is achieved by incorporating new kinds of joinpoints, pointcuts and advice into the aspect language. These new elements, which form what we call a meta joinpoint model, are dedicated to the aspect level and enable programmers to reason about and act upon the semantics of aspects at runtime. As validated on numerous examples of aspect composition, having a well-designed and principled meta joinpoint model makes it possible to deal with both the detection and the resolution of composition issues in a way that preserves the separation of concerns principle. These examples are illustrated using Phase, our prototype reflective AOP language. Doctorat en Sciences info:eu-repo/semantics/nonPublished

Abstract:

There has been an increase in demand for efficient wireless systems. Smart antennas using position location are one possible way to improve the capacity of cellular systems. In order to deploy such systems successfully, the wireless network must properly exploit the processing of spatial information (ie. The uplink angle of arrival) through wireless channel models. Geometric modelling is a technique to model the wireless environment. When compared to other methods such as ray tracing simulations, geometric models allow one to classify a wide varity of environments within a single model. Secondly, there have been much research in the past to obtain empirical measurements in many different environment settings. These measurements have been recorded, however, there has been no research undertaken to systematically compare and validate the empirical findings with current geometric models. The goal of this research is to compare and constrast geometric models with empirical data in order to show which models are best suited for specific wireless environments. The uplink angle of arrival (AOA) probability distribution is the fading metric that will be used to compare and contrast these models.

Abstract:

This study preliminarily identified clinical supervision competencies needed for alcohol and other drug abuse (AODA) clinical supervisors for integration into rehabilitation counselor training (RCT) curriculum. The Delphi method via LimeSurvey® was utilized to identify competencies specific to AODA clinical supervision. A panel of six experts in RCT and AODA clinical supervision completed five rounds of data collection beginning with an open-ended question. Consensus and stability of responses were calculated following Rounds 2-5 of data collection. Panelist fatigue resulted in data collection being discontinued after Round 5, prior to a consensus or stability of responses being reached. A total of 115 competencies and 51 competency sub-items were administered in Round 5. Results suggested that a consensus was not reached on items as one panelist represented a minority view on many items during multiple rounds of data collection. This panelist discontinued responding during the fifth round of data collection. Rank analysis of items based upon mean response was inconclusive due to limited sample size and response options. Sub-item analysis revealed mixed results regarding original competencies versus sub-items. At times a competency was rated higher, at times a sub-item was rated higher, and in other examples a second sub-item was rated higher. A clear pattern of responses for sub-items was not evident upon visual inspection of mean responses. Content analysis with two reliability raters in addition to the primary investigator suggested competencies fell into seven content areas: Legal and Ethical Concerns; Organizational Management, Administration, and Program Development; Personal Characteristics and Skills of Leadership; Supervisee Performance Evaluation and Feedback; Supervisory Relationship; Theory, Roles, and Interventions of Clinical Supervision; and Treatment Related Knowledge and Skills. Implications for the field, supervisors, supervisees, and rehabilitation educators; limitations including panel and data collection, technology, and reliability and validity; and future research were discussed.

Abstract:

The Federal Communications Commission (FCC) has adopted regulations requiring wireless communication service providers to provide position location (PL) information for a user requesting E-911 service. The Time Difference of Arrival (TDOA) technique is one of the most promising position location techniques for cellular-type wireless communication systems. The IS-95 Code Division Multiple Access (CDMA) system is a popular choice for the companies deploying new cellular and PCS systems in North America. Hence, the feasibility of TDOA techniques in CDMA systems is an important issue for position location in the wireless systems of the future. This thesis analyzes the performance of TDOA techniques in the CDMA systems. A comparison and assessment of different algorithms for finding the time difference estimates and for solving the hyperbolic equations generated by those estimates has been made. This research also considers a measure of accuracy for TDOA position location method which is shown to be more suitable for CDMA systems and more closely matches to the FCC requirements. Among the other contributions is a proposed method to perform cross-correlations to identify only the desired user's TDOA in a multiuser environment. This thesis also evaluates the feasibility and accuracy of TDOA techniques under varying system conditions that might be encountered in real situations. This includes varying conditions of Additive White Gaussian Noise (AWGN), Multiple Access Interference (MAI), power control and loading. The effect of the mobile position and of different arrangement of base stations on TDOA accuracy is also studied. Performance comparison in AWGN and Rayleigh fading channels is made. The feasibility of using increased power levels for the 911 user in combination with interference cancellation is also studied. The effect of using a single stage of parallel interference cancellation at neighboring cell sites has also been explored. Non-ideal situations such as imperfect power control in CDMA operation has also been investigated in the context of position location. This thesis also suggests amethod to correct TDOA estimation errors in CDMA. It is shown that this improvement can give greatly improved performance even under worst-case situations. Performance comparison of results with and without that modification has also been made under various conditions. Master of Science

Abstract:

Florações de cianobactérias são facilmente encontradas, devido ao crescente aporte de nutrientes nos corpos de águas naturais e artificiais, ocasionado pelos acelerados processos de eutrofização frutos da ocupação urbana e rural sem a observação de critérios mínimos. Microcystis aeruginosa é uma espécie de cianobactéria potencialmente produtora de cianotoxinas, comumente associada a casos de intoxicação em escala mundial. Novas tecnologias para o tratamento de água têm sido implementadas para cumprimento dos padrões de potabilidade exigidos pela legislação. O presente trabalho buscou analisar a produção científica mundial relacionada ao tratamento de água com presença de M.aeruginosa e MCLR, buscando identificar o estado da arte, além de embasar a discussão dos métodos propostos. O presente estudo está dividido em três artigos, no primeiro realizou-se uma análise bibliométrica das pesquisas mundiais relacionadas à cianobactérias, cianotoxinas e o tratamento de água, a partir da base de dados Scopus. No segundo artigo buscou-se avaliar a aplicabilidade dos AOPs UV-C e UV-C/H2O2 na degradação de Microcystis aeruginosa BB005 e MC-LR, e a análise dos efeitos da adição de nanopartículas de Ag, com base em um produto comercial composto por peróxido de hidrogênio (H2O2) e nanopartículas de prata (NAg). No terceiro artigo buscou-se avaliar a qualidade da água produzida a partir de ensaios de toxicidade aguda com Daphnia magna. Os resultados indicam que a fotólise e o processo UV-C/H2O2 apresentaram resultados satisfatórios, sendo uma alternativa eficiente. Porém, os resultados dos ensaios de ecotoxicidade inferem que estes tratamentos utilizados com a finalidade de degradar M. aeruginosa e MC-LR, possuem potencial de geração de subprodutos de degradação tóxicos: os ensaios com D. magna demonstraram toxicidade mesmo quando a água submetida a fotólise foi diluída quatro vezes. Com relação ao processo UV-C/H2O2 (sem e com adição de NAg), a amostra foi tóxica quando não diluída. Já quando empregada as NAg combinadas a radiação UV-C, esta apresentou toxicidade extremamente alta, afetando a mobilidade de todos os organismos teste em todas as diluições (até 16 x). Cyanobacterial blooms are easily found, due to the increasing nutrient supply in natural and artificial bodies of water, caused by the accelerated processes of eutrophication, fruits of urban and rural occupation without observing minimum criteria. Microcystis aeruginosa is a specie of cyanobacteria that are potentially cyanotoxin-producing, commonly associated with cases of worldwide intoxication. New technologies for water treatment have been implemented to meet the standards of potability required by legislation. The present study looked for analyze the world scientific production related to the treatment of water with presence of M. aeruginosa and MC-LR, seeking to identify the state of the art, besides supporting the discussion of the proposed methods. The present study is divided into three articles, the first one was a bibliometric analysis of the world-wide research related to cyanobacteria, cyanotoxins and water treatment, from the Scopus database. In the second article evaluated the aplicability of UV-C e UV-C/H2O2 AOPs on degradation of Microcystis aeruginosa BB005 and MC-LR, and the analysis of effects Ag nanoparticles addition, based on a commercial product composed of hydrogen peroxide (H2O2) and silver nanoparticles (NAg). In the trird article evaluated the water quality produced, from acute toxicity tests with Daphnia magna. The results indicate that photolysis and the UV-C/H2O2 process presents satisfactory results, being an efficient alternative. However, the results of the ecotoxicity assays infer that these treatments used for the purpose of degrading M. aeruginosa and MCLR, have potential to generate toxic degradation byproducts: the D. magna assays demonstrated toxicity even when the water submitted to photolysis was diluted four times. Regarding the UV-C/H2O2 process (without and with NAg addition), the sample was toxic when undiluted. When NAg was used in combination with UV-C radiation, it showed extremely high toxicity, affecting the mobility of all test organisms at all dilutions (until 16x).

Abstract:

The aim of this study was to characterize markers of oxidation of proteins in cattle, developing the assay method of AOPP (advanced oxidation protein products). Using standard commercial proteins (Bovine serum Albumin, bovine g-Globuline), oxidations In vitro were performed with chlorinated oxidant (hypochlorous acid) and hydroperoxide (cumene hydroperoxide) determining the relationship between AOPP and carbonyl groups by spectrophotometric and Western blotting analysis. The conformational changes of the standards were observed by one-dimensional electrophoresis kept in non-reducing conditions. In the second part of this project, we have studied the relationship between inflammation indicators and AOPP in both healthy cow and in animals with inflammatory processes, supporting the hypothesis that AOPP are specific indicators of protein oxidation by chlorinated oxidants produced by neutrophilis. The third part of the work has focused on the production of oxidative standard protein (AOPP-BSA) for the development of ELISA systems to detect autoantibodies directed against epitopes of oxidized proteins. Lo scopo del presente studio è stato quello di caratterizzare indicatori dell’ossidazione delle proteine nella specie bovina, sviluppando la metodica del dosaggio delle AOPP (advanced oxidation protein products). A partire da standard proteici commerciali (Albumina bovina e g-Globuline bovine) sono state eseguite delle ossidazioni in vitro con ossidante clorurato (acido ipocloroso) ed idroperossido (Cumene idroperossido) determinando la relazione tra AOPP e gruppi carbonilici tramite analisi spettrofotometriche e densitometriche tramite Western blotting. Le modificazioni conformazionali degli standard sono state osservate mediante elettroforesi monodimensionali mantenute in condizioni non riducenti. La seconda parte del progetto sono state studiate le relazioni tra indicatori del processo infiammatorio e le AOPP in animali sani e/o con processi infiammatori in atto, avvalorando l’ipotesi che le AOPP siano degli indicatori specifici dell’ossidazione proteica da parte di ossidanti clorurati di origine neutrofilica. La terza parte del lavoro si è focalizzata sulla produzione di standard proteici ossidati (AOPP-BSA) per la messa a punto di sistemi ELISA per l’individuazione di autoanticorpi diretti contro epitopi ossidati delle proteine.

Abstract:

We have created an eight-element antenna array system for evaluating various Angle of Arrival (AOA) Position Location (PL) algorithms, such as MUltiple SIgnal Classification (MUSIC) and Estimation of Signal Parameters via Rotational Invariance Techniques ESPRIT algorithms. Since using delay of arrival information can improve AOA estimates and classical PL algorithms do not incorporate Delay of Arrival (DOA) information, the performance of these algorithms is not optimal. Recently proposed Joint AOA and DOA Estimation (JADE) algorithms, though more complicated, potentially have higher resolutions in both space and time domains. Our investigation shows that by using bandlimited known signals it is possible to resolve the DOA within a fraction of the sample period using JADE algorithms. Joint AOA and DOA algorithms can provide high resolution DSP-based channel measurement using low bandwidth hardware. Master of Science

Abstract:

Advanced oxidation processes (AOPs) have been used to treat drinking water and wastewater but their application to greywater is limited to photocatalysis. Therefore, three homogeneous AOPs were investigated in this project: Fenton, photo-Fenton, and UVC/H2O2 processes. Alum and ferrous sulphate coagulation were also compared and their supernatants were treated by UVC/H2O2. The process comparisons were based on the removal of chemical oxygen demand (COD), treatment type (physical separation versus chemical oxidation), sludge formation, complexity in operation, required pH, visual aesthetic of effluent and energy requirement. Treating greywaters collected from the researcher's home or laboratory, alum coagulation achieved 73% COD removal and was more effective than ferrous sulphate coagulation (49%) and the Fenton process (45%). The photo-Fenton process removed 83% COD, compared with 87% by overnight settlement and subsequent UVC/H2O2 treatment. Using ferrous sulphate and alum, sequential coagulation and UVC/H2O2 treatment removed 91% and 98% COD, respectively. Overnight settlement generated little sludge and the subsequent UVC/H2O2 treatment removed most organic contaminants by oxidation. All other processes produced a large quantity of chemical sludge from coagulation which requires appropriate disposal. Also, the residual iron in some treated water was not aesthetically desirable. The Fenton and photo-Fenton processes were complex and involved the optimisation of multiple parameters. Their requirement for different procedures according to the greywater type presents a major challenge to process design and operation. Due to the non-selectivity of the hydroxyl radicals (●OH), the UVC/H2O2 process was capable of treating all greywaters collected by the researcher, and its operation was moderate in complexity. The COD removal was modelled as a pseudo first-order reaction in terms of H2O2 dosage: The rate constant (k´) increased linearly up to 10 mM H2O2, above which the excess H2O2 scavenged the ●OH and reduced the rate. The overall kinetics of COD removal followed a second-order equation of r = 0.0637 [COD][H2O2]. In contrast to the literature, operation of UVC/H2O2 in acidic conditions was not required and the enhanced COD removal at the initial pH of 10 was attributed to the dissociation of H2O2 to O2H-. Maintaining the pH at 10 or higher resulted in poorer COD removal due to the increased decomposition rate of H2O2 to O2 and H2O. The performance of the UVC/H2O2 treatment was unaffected for initial pH 3 - 10 with the initial total carbonate concentration (cT) of 3 mM. For initial cT ≥ 10 mM, operating between pH 3 and 5 was essential. After 3 hours of the UVC/H2O2 treatment, the effluent met the requirement of Class B reclaimed water specified by the Environment Protection Authority of Victoria, and less than 1 org/100 mL of Escherichia coli survived. A subsequent treatment such as filtration may be required to meet more requirements for biochemical oxygen demand (BOD5), turbidity and total suspended solids. Since the biodegradability (as BOD5:COD) of the greywater was increased from 0.22 to 0.41 with 2 hours of UVC/H2O2 treatment, its integration with a subsequent biological treatment may be viable to reduce the costs and energy consumption associated with the UVC/H2O2 process.

Abstract:

Hazardous and recalcitrant pollutants in the environments have led to a great many environmental issues these days. Many researchers have focused on the approaches to treatment of these pollutants which contaminate environments such as soil, surface and groundwater. As an advanced oxidation processes (AOPs), sonolysis which is the oxidation technology involving the use of ultrasonic irradiation, has proven to be successful for the treatment and remediation of contaminated environments. In this thesis, hydrogen peroxide formation and formic acid degradation by ultrasonic irradiation of well-characterised solutions are described under various conditions in order to determinate reaction mechanism by which peroxide degradation and contaminant degradation occur. The effect of gas properties and frequency on hydrogen peroxide and formic acid degradation are examined. Experimental results obtained are analyzed in light of the reactions occurring. Successful mathematical modeling of the result s obtained confirms that, for the most part, hydrogen peroxide and formic degradation occur by free radical generation within bubbles with subsequent transfer of these radicals to the bubble-water interface where the majority of the degradation occurs. The effect of Fe(II) addition which can lead to Fenton reactions in the bulk solution are also investigated. Experimental and model results show that the heterogeneous reactions can enhance the degradation of formic acid in the presence of Fe(II). Oxidation of phenol by ultrasonic irradiation under a variety of initial conditions and solution environments is also described and validated by a simple kinetic model. The model developed will be useful for improving our understanding of free radicals behaviour and the interplay between free radical generation and contaminant degradation.

Abstract:

Stalno praćenje rada softvera je neophodno da bi se utvrdilo da li softver po&scaron;tuje zadate nivoe kvaliteta. Na osnovu sakupljenih podataka, moguće je da se predvidi i dalje pona&scaron;anje aplikacije i da se izvr&scaron;i izbor daljih akcija da bi se održao zahtevani nivo. Tema ove disertacije je razvoj sistema za kontinualno praćenje performansi softvera, kao i razvoj modela za predviđanje performansi softvera. Za implementaciju sistema potrebljena je JEE tehnologija, ali je sistem razvijen tako da može da se primeni i za praćenje softvera razvijenog za druge platforme. Sistem je modelovan tako minimalno utiče na performanse sistema softvera koji se prati. Linearna regresija je upotrebljena za modelovanje zavisnosti performansi od okruženja u kom se softver izvr&scaron;ava. Sistem je upotrebljen za praćenje izabrane JEE aplikacije. Continuous monitoring of software is necessary to determine whether the software performs within required service perfomance levels. Based on collected data, it is possible to predict the future performance of applications and to plan further actions in order to maintain the required service levels. The theme of this dissertation is the development of systems for continuous performance monitoring software, as well as the development of models for predicting the performance of software. To implement the system was used JEE technologies, but the system was developed so that it can be used for tracking software developed for other platforms. The system is modeled as a minimum impact on system performance software that is monitored. Linear regression was used for modeling the dependence of the performance environment in which the software is running. The system was used to monitor selected JEE applications.

Sendo assim, cita-se o desenvolvimento da UML para representar um software que utiliza o paradigma de desenvolvimento orientado a objetos, o qual tem algumas funcionalidades que estão espalhadas durante todo o software dificultando a implementação e conseqüentemente a evolução. Então, com vistas a solucionar esse problema, propõem-se a utilização do paradigma de desenvolvimento orientado a aspecto para suprir a carência do paradigma orientado a objeto.

Thus, the development of the UML is mentioned in order to represent a software that uses the development paradigm oriented to objects, which has some functionalities that are spread throughout the software, making it difficult for its implementation and consequently its the evolution.

Este trabalho propõe o desenvolvimento de uma metodologia para a implementação da aprendizagem orientada por projetos, buscando contribuir com outros enfoques para o aprimoramento contínuo do ensino de graduação. A elaboração didática de projetos foi a estratégia escolhida, por apresentar a mesma estrutura cognitiva (raciocínios, operações mentais, comportamentos, atitudes e posturas) da atividade profissional, bem como por caracterizar um contexto integrado de conceitos teóricos, atividades práticas, tomadas de decisão e vivências que deverão constituir o aprendizado dos estudantes. A Aprendizagem Orientada por Projetos (AOPj) permite que os estudantes tenham articulação com a realidade profissional, relacionamento entre teoria e prática, desenvolvimento das competências transversais, como realização de atividades colaborativas, apresentação de idéias e problemas de forma adequada, comunicação oral e escrita, condução de reuniões, tomada de decisão, gerenciamento de conflitos e projetos. Este trabalho possui três características que o torna singular: grande número de estudantes envolvidos, aproximadamente 180 (cento e oitenta); envolvimento de estudantes de níveis diferentes, sendo 4o, 5o, 7o e 8o (quarto, quinto, sétimo e oitavo) semestres; pouca interferência dos professores junto aos estudantes, pois é esperado que eles sejam autônomos em seus trabalhos. Foram realizadas 3 (três) experimentações da metodologia proposta, neste trabalho, as quais aconteceram em 2007/2, 2008/1 e 2008/2. Finalmente, os resultados coletados são extremamente satisfatórios, uma vez que os estudantes têm se mostrado motivados, empenhados e a cada dia mais autônomos, responsáveis e assertivos nas tomadas de decisões nos projetos. _________________________________________________________________________________ ABSTRACT The Ministry of Education, regarding engineering education, through its curriculum guidelines, has been working in the direction of graduation courses with flexible curriculum, pedagogical student centered approaches, allowing the professional future to have permanent articulation with the professional reality, emphasis on the interdisciplinary, social and political integration, environmental awareness, and relationship between theory and practice. This work suggest the developing of a methodology to implementation of the project-based learning, trying to contribute with other approaches to the continuous improvement of the graduate teaching, reporting the implementation of the project-based learning at the University of Brasilia. The use of didactic projects was the strategy chosen by the same structure cognitive (reasoning, mental operations, behaviors, attitudes and postures) of professional activity, and characterized by an integrated context of theoretical concepts, practical activities, decision making and experiences that should be the learning of students. The Project-Based Learning (PjBL) thread allows the students to have articulation with the professional reality, relationship between theory and practice, developing their soft skills, such as accomplishment of collaborative activities, explanation of ideas and problems in an accessible way, oral and written communication, conduct of meetings, decision making, conflicts management and projects management. This thesis employs three different subjects: involvement of students from different grades, being 4th, 5th, 7th and 8th grades; a great number of students, approximately one hundred and eighty; and little interferences of the professors, as it is expected that the students are autonomous on their works. We performed (3) three experience of the methodology proposed in this work, which happened in 2007/2, 2008/1 and 2008/2. Finally, the findings are extremely satisfactory, pointing out an increase of the student’s motivation and commitment and to have more autonomy, responsibility and assertiveness in making decision throughout the projects.

Abstract:

El presente trabajo de título tuvo como objetivo el diseño de un modelo de negocio para el servicio de asesoría creado por la Gerencia Técnica de la Asociación de Oficinas de Arquitectos (AOA), entidad gremial con más de 150 oficinas afiliadas. Gracias al estudio “Caracterización de mercado frente a la eficiencia energética y certificación verde” de la Corporación de Fomento de la Producción y el Programa País Eficiencia Energética (Agosto 2007), se logró determinar que los atributos asociados a la eficiencia energética son valorados por el consumidor y que, además, para los agentes inmobiliarios resulta atractivo incorporar aspectos innovadores en sus productos. Sin embargo, se observó que existe falta de comunicación entre los agentes que manejan el conocimiento técnico y los gestores inmobiliarios. En base a esto, se desprende el diseño de un modelo de negocio que brinda una nueva herramienta de gestión a los desarrolladores de proyectos asociados a la eficiencia energética y construcción sustentable. Contempla el apoyo en tres aspectos fundamentales de la génesis de un negocio inmobiliario, el diseño de las viviendas, la selección de proveedores y el plan de difusión. Además, este servicio contempla como alternativa el apoyo en la inclusión al Mecanismo de Desarrollo Limpio y la certificación del proyecto bajo los estándares LEED (Liderazgo en Energía y Diseño Ambiental), un potencial nicho, que comienza a crecer gracias a las medidas de fomento incentivadas por entidades públicas y privadas. Respaldado por la AOA y su Gerencia Técnica, gracias al servicio de asesoría integral se lograría producir mejoras tecnológicas, cambios de patrones de comportamiento en el uso de la energía y un mejoramiento de la eficiencia económica de los procesos productivos, obteniendo como resultado final un producto inmobiliario diferenciado y de calidad. Junto con esto, se potencia el “mercado verde” y se posiciona a la AOA como plataforma de transferencia tecnológica, permitiéndole fortalecer su posicionamiento en el mercado inmobiliario sustentable. Finalizado el diseño, se realizó una evaluación económica de la implementación del servicio, obteniéndose un valor presente neto de veintitrés millones doscientos mil pesos y una TIR de 37%, descontando los flujos proyectados a una tasa de descuento de 10%, en un horizonte de evaluación de 10 años. La inversión, evaluada en aproximadamente cinco millones doscientos cincuenta mil pesos, se estimó será recuperada en un periodo de 4 años.

Abstract:

Wastewater treatment is not a new concept as water bodies around the world have been polluted since the dawn of industrialisation. With the increase in human activities, including domestic, industrial, and commercial practices, water pollution levels continue to rise due to aqueous contaminants. In addition, rapid industrialisation and recent human progress have given rise to a new form of pollution - emerging contaminants (ECs) - which are highly resistant to biodegradation and can travel across the world. While traditional wastewater treatment methods, such as adsorption, can combat these chemicals, their production of sludge is a major drawback that leads to secondary contaminants. Advanced oxidation processes (AOPs) have emerged as a prominent choice among other wastewater remediation technologies owing to their ability to convert emerging organic pollutants to less toxic compounds through complete oxidation, such as mineral salts, CO2, and H2O. AOPs rely on the generation of reactive radicals to attack pollutants, however, the performance of AOPs for environmental remediation depends on the availability of a suitable catalytic material that can provide sufficient active sites for completing the redox reactions and can be efficiently recovered and reused. Recently, graphene and its derivatives, such as reduced graphene oxide (rGO), have demonstrated high efficiencies for the catalytic oxidation of aqueous pollutants, thanks to their extremely large specific surface area, superior interfacial charge transfer properties, and excellent functional chemistry. The self-assembly of rGO into three-dimensional (3D) macrostructures further enhances its catalytic properties, making it a promising candidate for large-scale operations. Taking advantage of 3D graphene-based materials, this thesis presents novel remediation technologies for wastewater treatment. Macroscopic graphene-based materials were fabricated and modified through various techniques, such as structural manipulation, heteroatom doping and integration with other carbonaceous materials, to enhance their catalytic activity in AOPs. Different facile techniques such as coagulation and cross-linking, freeze-casting and annealing, and hydrothermal and hydraulic pressing were employed to fabricate 3D macrostructures. The physical and chemical properties of the prepared materials were characterised using advanced techniques such as Raman spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, electron microscopy, and Fourier-transform infrared spectroscopy, among others. The catalytic activity of the prepared materials was evaluated by applying them in AOPs using peroxygens (peroxymonosulfate - PMS and peroxydisulfate - PS) to remove 4-hydroxybenzoic acid (HBA) and sulfamethoxazole (SMX) from wastewater. The primary performance indicator in this thesis was the extent of modification, where optimal modification conditions were identified to maintain the best catalytic properties. The influence of various reaction parameters on the reaction kinetics was investigated, and electron paramagnetic resonance coupled with selective radical quenching was used to identify the radical and free radical species generated during the AOPs. The mineralisation ability of the prepared materials was evaluated using ultra-high performance liquid chromatography. The results showed that the prepared macroscopic graphene-based materials exhibited excellent catalytic activity for the removal of ECs from wastewater using AOPs. This PhD study provides a fundamental basis for the development of efficient and sustainable graphene-based materials for real-world applications in wastewater treatment.

La thèse a porté sur la localisation de mobile pour les systèmes UMTS-FDD. Il s'agit d'un sujet qui intéresse de plus en plus les opérateurs, notamment dans le cas de système UMTS-FDD où il existe très peu de réseaux réels. Les différentes approches permettant de localiser un émetteur ont ainsi été envisagées, et plus particulièrement, celles basées sur les mesures de puissances, les temps d'arrivée (TOA) en liaison descendante ou encore celles basées sur les angles d'arrivée (AOA) et sur toute combinaison AOA-TOA. Pour ces différentes approches, nous nous sommes intéressés aux deux principales sources d'erreur pouvant dégrader les performances de la localisation : -l'absence de trajet direct qui est une des caractéristiques des systèmes radio-mobile. -le problème d'écoute, qui est inhérent au système UMTS-FDD. A ces deux problèmes, nous avons proposé des solutions pour les differentes approches de localisation, qui soient à la fois précises et facile à mettre en oeuvre au niveau de la norme.

Full text

Abstract:

Aspect oriented programming is a relatively new programming paradigm aimed at improving the development of software through a mechanism that allows for crosscutting concerns to be better modularized. Such concern crosscutting is an element of software artifacts that affects one or more quality attributes and ultimately the ability of software to evolve to meet new functional requirements, or to take advantage of new hardware, or meet new business rules. The aim of this dissertation was to explore the relationship between the degree of crosscutting present in a software artifact and its evolvability. This research study illustrates the correlation between the homogeneity of a program's features and its ability to evolve. Throughout the study, such correlation was drawn from a three pronged approach, first by looking at measuring how invasive code changes are, second by identifying a measurable evolvability indicator, and third by using such indicator to propose changes in program constructs that can enhance or improve the evolvability of it. This study proposed the use of existing concern crosscutting metrics to measure invasiveness of code changes and the variability of such measurements to infer a measurable evolvability indicator. Through this approach a number of contributions were made to the body on knowledge, first the creation of a way to quantify evolvability of Aspect Oriented programmed software, and secondly, a way of identifying parts of an Aspect Oriented artifact that can contribute to the deterioration of the system by hindering its evolvability.

Abstract:

The practice of literate programming is not widespread because existing literate programming systems have some undesirable characteristics such as programming language and text processor dependence and lack of flexible tools for viewing and manipulation of the source file. This dissertation describes the literate programming system AOPS (Abstraction Oriented Programming System) which addresses both of these problems. AOPS is programming language and text processor independent literate programming system. AOPS tools include a hypertext browser, a lister with the ability to select what is presented and what is suppressed, and a filter to extract the program code from the AOPS source file. AOPS introduces the notion of a phantom abstraction that enhances the understandability of the literate program and when used in conjunction with the browser greatly extends the capabilities of AOPS. We also discuss how the design of AOPS supports extension of the concept of literate programming to encompass the entire software life cycle. Finally we describe an experiment which showed that literate programs contain more documentation than traditional programs. Graduation date: 1993

The 2D DPWT was widely used in many researches of digital signal processing, image coding, compression, digital image processing, and pattern recognition. Since the 2D DPWT is the kernel of MPEG-4 and JPEG-2000 vedio compression standard. To obtain perfect reconstruction, DWT is the most convenient choice. Now the study about the VLSI architecture for the inverse DWT is very less. So that this paper, we present a new inverse algorithm and architecture based on the AOCA algorithm to improve the original operation. There is more efficient to obtain perfect reconstruction.　 In this paper, we will firstly develop a Verilog program for VLSI architecture simulation. Then the Synopsys tool and FPGA technology will be applied for VLSI architecture implementation.

Abstract:

碩士 國立交通大學 電信工程研究所 104 Localization has been an important issue in wireless systems. Many methods have been proposed to solve the problem. However, most methods were developed for line-of-sight (LOS) scenarios. Recently, a single-bound scattering (SBC) model has been proposed to solve non-LOS (NLOS) localization problem using time-difference-of-arrival (TDOA), angle-of-arrival (AOA), and angle-of-departure (AOD). Although this method is effective, only a single scattering path is considered for a wireless link. Also, how to obtain TDOA, AOA, and AOD observations are not discussed. This thesis is aimed to solve the problems. First, a SBC model with multiple scattering paths and the corresponding localization method are developed. Then, a joint channel, AOA, and AOD method is applied to obtain the observations. Finally, a particle-filter-like algorithm is developed to solve the local minimum problem frequently encountered in localization algorithms. Simulations show that the proposed method can yield satisfactory results and it significantly outperforms the existing method.
