The new CAP 2030 foresees the need to a rationally use of inputs, so that mechanization plays a decisive role in achieving this objective. Thus, in 2021 agricultural year, within the scope of the ISOmap Forage Project ALT20-03-0246-FEDER-000062, a set of works were carried out considering the application of variable rate products and the use of ISOBUS technology in the communication of data between tractors and agricultural machines from different manufacturers. Two operating machines were used, a fertilizer spreader and a jet sprayer that worked either with the respective electronic controller or with the virtual terminal of an agricultural tractor. Data files for application at a variable rate resulted from field evaluations of the ISOmap Forragem project, and its operation was carried out using open access online digital software and platforms. At the end of the work, it can be concluded that the use of ISOBUS technology made it easier the communication between tractor and implements from different manufacturers for the application of products at a variable rate, despite the need for operator training and investment in the update of the respective agricultural machinery.

Eklund, Pauline. "Implementering av ISOBUS på ECU vid Ålö AB." Thesis, Umeå universitet, Institutionen för tillämpad fysik och elektronik, 2017. http://urn.kb.se/resolve?urn=urn:nbn:se:umu:diva-137147.
En seriell buss kallad ISOBUS baserat på CAN blir allt vanligare inom jordbruk- och skogsindustrin. Bussen reglerar hur kommunikationen mellan traktorer och redskap fungerar. Tidigare har varje redskap haft en egen monitor för att se över redskapets funktioner, vilket innebär att det kan bli många skärmar i traktorhytten. Med ISOBUS behövs bara en monitor, så kallad VT (Virtuell Terminal), oavsett tillverkare av redskapet. Syftet med detta examensarbete är att implementera ISOBUS på Ålö:s ECU (Electronic Control Unit) för att denna ska kunna presentera sina funktioner på VT. Målet är att integrera ett inköpt tredjeparts kommersiellt ISOBUS bibliotek på ECU. Arbetet för att uppnå ISOBUS kompatibilitet utan tredjepartsbiblioteket skall uppskattas, och om tid finns utföras. En objektpool baserat på Ålös existerande gränssnitt ska skapas, där objektpoolen är det grafiska interface som visas på VT. En demonstrator av ISOBUS VT skall sättas upp. För att implementera tredjepartsbiblioteket krävde biblioteket hårdvarufunktioner mot CANbussen. Hårdvarufunktionerna tar bland annat emot meddelanden från en buffert och skickar ut meddelanden direkt på bussen. För att biblioteket skulle vara igång och köra måste det initieras och ett periodiskt anrop göras till biblioteket. Resultatet är att biblioteket implementerades på ECU och att det flödar trafik mellan ECU och VT. För att uppnå ISOBUS kompatibilitet utan tredjepartsbibliotek måste det existerande protokollet på Ålös ECU bytas ut med ett grundstöd för ISOBUS. Sedan måste en egen del skrivas för att uppnå full kompatibilitet. Här behöver bland annat kommandon som ISOBUS standarden definierar mellan ECU och VT skrivas, samt callbackfunktioner som anropas då VT skickar kommando till ECU. Hantering av svar och felmeddelanden vid kommunikation måste också implementeras. Att uppnå ISOBUS kompatibilitet utan tredjepartsbibliotek hann inte utföras, däremot uppskattades arbetet och en översiktlig beskrivning om vad som behöver utföras gjordes. Slutsatsen är att det kräver väldigt mycket arbete och finläsning av standarden. Fördelen är att man får en inblick i hur systemet fungerar och möjligheten att påverka funktionaliteter själv. Objektpoolen utformades efter hur Ålös existerande gränssnitt ser ut. Menysystem implementerades, samt att streckdiagram och en cirkulär mätare har möjligheten att visa höjd och vinkel på traktorskopan. Olika sätt för att visa ett menysystem har diskuterats. Resultatet är en objektpool med grundläggande funktioner för Ålös gränssnitt, demonstratorn visar dessa funktionaliteter. Resultatet visar på att det går att få gränssnittet för VT ganska likt Ålös existerande, med vissa skillnader som typsnitt, bildkvalité och menyfunktioner.
Öberg, Anders. "Implementering av ISOBUS Virtual Terminal på fordonsdatorn CCP XS." Thesis, Linköping University, Department of Electrical Engineering, 2005. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-5247.
Modern agriculture equipment are more computer based today, and many equipments use a terminal in the tractor where the driver have the opportunity to make adjustments to the equipment. This is the reason why ISO developed a new standard called ISOBUS. It is a communication standard based on CAN specially adapted for griculture equipments. The purpose of the standard is that it should be ossible to equip a tractor with a standard terminal called Virtual Terminal that can be used to control the equipment. The use of the terminal should be independent of the manufacturer of the tractor as well as of the equipment.
The purpose of this report is to find a solution of how to use CC Systems on-board computer, CCP XS, as a Virtual Terminal. In the report both Hardware and Software requirements have been examined, but mainly the software requirements. Only one suitable software vendor, Vector Informatik, was found after contacts with different software suppliers. It have not been possible to test this package because of the high price for the evaluation license.
A demonstration solution has also been developed in the project. It consists of a simulator program, that runs on a PC, connected to a CPP XS that executes a Virtual Terminal program. An ISOBUS compatible J1939 protocol stack from Ixxat Automation has been integrated in the Virtual Terminal program. It gives the opportunity to test the protocol stack on a CPP XS. In order to limit the size of the project, not all functions in the ISOBUS standard is implemented in the demonstration solution.
Moderna jordbruksredskap har blivit allt mer datoriserade och många använder sig av en terminal i traktorn där föraren har möjlighet att göra inställningar på redskapet. Därför har en standard för detta tagits fram av ISO kallad ISOBUS. Det är en kommunikationsstandard baserad på CAN speciellt framtagen för jordbruksmaskiner. Syftet med standarden är att en traktor skall kunna vara utrustad med en standardterminal kallad Virtual Terminal som används för att styra redskapen. Denna terminal skall kunna användas till samtliga redskap som kopplas till traktorn oberoende av vem som tillverkar redskapen eller traktorn.
Syftet med rapporten är att hitta en lösning för hur CC Systems fordonsdator CCP XS kan användas som en Virtual Terminal. I rapporten har dels kraven på hårdvaran undersökts men det största arbetet har lagts på att hitta en lämplig mjukvarulösning. Efter att ha kontaktat olika leverantörer av mjukvara har endast ett lämpligt mjukvarupaket hittats och det levereras av Vector Informatik. Dock har inte detta paket kunnat testas på grund av det höga priset
på en utvärderingslicens.
Det har också i projektet tagits fram en demonstrator som består av en simulator för PC som kopplas till en CCP XS som kör en Virtual Terminal mjukvara. I programvaran för Terminalen valdes en ISOBUS kompatibel J1939 protokollstack från Ixxat Automation att användas, för att få möjlighet att provköra den protokollstacken på CCP XS. För att arbetet inte skulle bli för stort har dessa programvaror begränsats till att endast stödja vissa funktioner i ISOBUSstandarden.

Precision Agriculture is one of the technological advances used to recoup the treatment of spatial and temporal variability in agricultural crops. Besides other benefits, it tries to improve the exploitation of applied inputs, improve the productivity and reduce production cost as well as lessen the impact on environment caused by excess of input. To achieve these benefits, information and communication technology are available in agricultural equipment such as computational systems, wireless communication, satellite orientation by the global positioning systems and ISO 11783 networks. Recently, Wireless Sensor Network has been introduced for agricultural environment monitoration. It is believed that the performance of these technologies can be improved with the interconnection of both networks. In this way, sensor data can be collected by the computer embedded in the vehicle, at the moment that the vehicle goes into the sensor signal area. The objective of this work is to propose and demonstrate the viability of this interconnection between the networks ISO 11783 and WSN in the Precision Agriculture context. Based on bibliographical research, both network ISO/OSI models were compared, the most adequate interconnection devices were identified and the interconnection was proposed. To demonstrate the interconnection viality in Precision Agriculture systems a simulator was denveloped which permited hundreds of simulations to be done in dozens of distint scenes. The results were shown in graphs which were analysed considering the agriculture application limitations. From this analisis, it was possible to conclude that the interconnection is viable, so that ISO 11783 computation units receive environmental data obtained by the Wireless Sensor Network in real time.

Precision agriculture and agricultural practices which take into account environment protection leads to several research challenges. Sampling scale and the precision required by these new agricultural practices are often higher than those required by traditional agriculture, raising the costs of production. This whole process requests an expressive number of researches in developing automation instruments. Among them, highlights the use of remote sensing techniques based on the use of On-the-Go sensors technology, coupled to a geographic information system adapted and developed for agricultural use. Aiming this, the application of agricultural mobile robots is a strong tendency, mainly in the European Union, USA and Japan. In Brazil, researches are necessary for the development of robotics platforms, serving as a basis for semi-autonomous and autonomous navigation systems, facilitating data acquisition in the field. The aim of this work is to describe the project of an experimental platform for data acquisition and for the development of autonomous vehicles technologies to operate in agricultural environments. The proposal is based on a systematization of scientific work containing the main methodologies and technologies employed in agricultural vehicles and robots, which were used as a basis for construction of the presented model. The platform shall allow acquisition of field data to study the spatial variability through sensors and equipment that will be loaded in the structure.

This work has base in the demand of research and development of data communication networks (fieldbus) to support the integration of control and automation devices for applications in agricultural systems. Agricultural systems related with the precision agriculture practices, with the embedded systems in agricultural machinery and with the greenhouses control and livestock systems. It is also guided by the efforts on the implementation of ISO11783 standard. The ISO11783 (also called ISOBUS) standard communication link is a common tendency to integrated different devices on agricultural machinery through an embedded control network. The ISOBUS use the controller area network (CAN) as a data link protocol to perform the data communication. The correct definition of the data link configuration parameters represents one of the main challenges related to the design of CAN-based networks. The definition of these parameters has influence in the performance of the analyzed network. This work presents the research and the development of a performance analysis tool of CAN-based networks for applications in agricultural systems. This development consists of the systematization and validation of a CAN mathematical model. An analysis methodology is proposed to use the mathematical model. A simulation software was built and implements the methodology. It is expected that the implemented methodology facilitates the analysis tasks of the configuration parameters of the applications. The result obtained may assist in the performance evaluation and in the definition of an optimized configuration for the network based on CAN protocol and ISO11783 standard.

The company engcon Nordic AB produces equipment for the construction industry, where the product called tiltrotator is the heart of their business. To improve the use and simplify the installation, a literature study has been made that looks at two parts, first the function around CAN bus as the basis for a communication system and secondly various higher layer protocols (HLP) built on top of CAN. Why CAN bus was created and how the system works is important to understand in order to look at these overlying layers, called HLP (Higher Layer Protocol), which provides a kind of machine-human interface to work with. Different types of HLP can be J1939, ISOBUS or other. CAN bus is the de facto standard for vehicle networks where ECUs (Electronic Control Unit), called nodes, communicating on a common communication network, called bus. To do this, an ingenious technique has been developed to prioritize messages between nodes, which provides data loss-free arbitration. In CAN an advanced technique for error detection on the communication has been applied, and gives CAN the robustness to be applied in tough environment. As for various HLPs, a large number of these are available in different industries. Every one of these HLP has a common that they try to build a more or less user-friendly interface that can be implemented on top of CAN. For example, in the agricultural industry, the use of ISOBUS is common, which is an industrial standard that goes beyond competition to build a simple, user-friendly system that benefits the customer to the best possible extent. In automation, instead, CANopen is used, which is an open system that allows high interoperability between different units with so-called profiling. One last system used in a number of industries is called CanKingdom and is the most adaptable system in this project. In order to find out more industry-specific information about solutions and problems, an interview study was also conducted within the project. Here, various people were interviewed, active in different companies that are involved in CAN-based systems. This was done to look at relevant problems in their specific area. As a result, four options are specified which the project owner should look at in order to find a system that suits them. It is based on alternatives that either require access to the existing J1939 bus, or to build a more or less adapted model built on ISOBUS, CANopen or CanKingdom.

The digital networks demonstrated to be an effective solution in automation. The connection of different modules from different manufacturers into a single bus for the exchange of data and control is a challenge for the agricultural machinery Brazilian industry, although this technology is consolidated in automobiles, aircraft and the factory floor. The benefits obtained with digital networks are obvious, but they need implementation of protocols networks. In the agricultural area, the international standard ISO 11783 shows strong potential to become the reference standard for the exchange of data between modules on tractors and agricultural implements. This standard, also known as ISOBUS, is in the advanced stage of development. It contains fourteen documents and its development is supported by groups called \"Task Force\" in Europe, USA, and recently in Brazil. Implementations of this standard are now being presented in the international market, in fairs and demonstrations of application of this technology. Brazil should invest and dominate the technology, to inquire after international compatibility in both the technological point of view as commercial. In this context, this work encourages the national development in applications with ISOBUS standard, presenting two studies of cases, whose modules communicate with equipment market compatible with the standard. These practical experiences complement academic works on this subject, which emerged in recent years in Brazil.

The recent growth of automation technology and embedded electronic in agricultural machinery has established a new practice in agriculture. These new practices related to precision agriculture (PA) have demanded the use of sensors and communications embedded networks for data acquisition and control devices in the farm field. The incompatibility between hardware, software and data formats has become a major obstacle. The global trend is to use standardized systems in accordance with ISO 11783 (also known as ISOBUS) in the devices, or Electronic Control Units (ECU), used in agricultural production. In Brazil, these tools are not yet implemented. The purpose of this work is to systemize the information necessary of the procedures for communication among the implement ECU with management tractor ECU. This work focuses standardized files format, the program of the implement ECU and the validation tests of the devices communication via ISO 11873 network. It was established the relation among the systematized information and embedded devices on agricultural machinery. The embedded devices consist in five ECUs connected in the ISO 11783 network. Four ECUs are located in the tractor: GPS ECU, Task Controller (TC), Virtual Terminal (VT) and Tractor ECU (TECU). The GPS ECU is responsible to the Differential Global Positioning System (DGPS) positioning. The TC is responsible to manage the prescription map and to control the implement. The VT is responsible monitor the application. The TECU disposes tractor velocity of a radar sensor. The fifth device located in the implement is Working Set Master (WSM), which is responsible to interpret the commands from the tractors ECUs and integrate the mechanical-hidraulical device instruction for agricultural operation. It was presented how to develop the needed standardized files (TaskData.XML and Device Description Object Pool), the capabilities needed of the implement ECU program, the validation of communication between the implement ECU with the TC (management tractor ECU) and was prove that the information systematized has facilitated and provided the communication. It is expect that this work may open opportunities for the ISO 11783 standard can be better understood and enlarge the possibility of providing a great number of applications involving the concept of AP in Brazil.

The use of on-board electronics in agriculture has grown quickly, requiring many electronic modules on-board machines (tractor and implement). Considering the trend related impacts, alternative technologies should be developed and used properly, especially on control systems and on the required wiring harness. Electro-electronic architectures should provide minimum implementation cost and maintenance related time. Control systems should operate maximizing the availability of information that implies on the necessity of data exchange among these variety of control systems and also, on the existence of an international standardized serial communication protocol. Considering that, this documentation covers many serial communication protocols - as RS232, RS485 and CAN (Controller Area Network) - and the agricultural applications related standards as ISO11783 and DIN 9684, comparing them. This analysis results in the indication of ISO11783, a CAN Bus based standard, as the most interesting to agricultural applications. This standard is analyzed in details, making possible the development of a protocol related study and implementation guideline. Finally, a protocol related application is developed for a Planter Monitor implement bus network, looking forward to demonstrating an ISO11783 real implementation.

From the movement of emigration in that of immigration, one observed at first the figure of the foreigner through that of workers, refugees, families. The migration of separated children and youngsters under 18 years old, “wenzhou”, “african” or “rumanian”, allows questioning the concepts of childhood and teenager. Mobile, they cross over several borders with landmarks, here and there, simultaneously and they request the encounter. Sometimes, considered as teenagers facing a lack of perspectives and leaving their homeland on their own searching a better future and sometimes, as exploited children. In any case, they appear in search of relations of affinities when they are allowed to speak. Consequently, they are subject to a double treatment: entitled to care measures and services as children “at risk” but removed and rejected as illegal immigrants. They generate a pendular movement of hostility and benevolence, estimating that is a question of gift and returned gift, of hospitality

The present dissertation is devoted to the study of the gestural languages created by native deaf signers who live in a hearing community and have had no contact with any other deaf persons apart from their own kin. Since they are illiterate and deaf by birth, their personal gesture languages can be considered as being created without any conventional linguistic models. During my several sojourns in the amerindian reservations of northern canada and in the rural areas of china from 1977 to 1986, i succeeded in localizing and studying a dozen subjects. The analysis of the cognito-visual constraints in their gestural creating process allowed me to compare the lexico-syntactic mechanisms involved with the parallel phenomena observed in oral child languages and chinese picto-ideographic writing

Algae order Caulerpales are known for their chemical defence against predators via terpenic toxins. Among toxins, metabolites having a diacetoxybutadiene moiety are presumed responsible for their biological activities. To understand their biological activities and to prepared labelled toxins, we have undertaken the first total synthesis of two metabolites: caulerpenyne and dihydrorhipocephaline. The first part of this work deals with the total synthesis of the caulerpenyne, the main toxin of Caulerpa taxifolia. It was carried out via the synthesis of another natural metabolite, the taxifolial A. Our strategy was based on the construction of three functionalised fragments which have been joined by various coupling reactions. Thus, (±)-taxifolial A was obtained, over 9 steps, in 16. 5 % overall yield, then (±)-caulerpenyne in 6 % overall yield. In a second part, using an analog strategy, the synthesis of (±)-dihydrorhipocephaline was achieved, over 7 steps, in 9 % overall yield. To confirm, by biological tests, the reactivity of diacetoxybutadiene moiety, a racemic then enantioselective synthesis, via enzymatic resolution step, of the two enantiomers of the furocaulerpine was exposed in a final chapter. Thus, (±)-furocaulerpine, (+)-furocaulerpine and (-)-rurocaulerpine were obtained in respectively 65 %, 15 % and 11 %

Background: Obesity is an increasing problem in Sweden and large parts of the world, for both adults and children. Overweight and obesity in the mother before and during pregnancy increases the risk of overweight and obesity in the child. The risk of childhood obesity is increasing in proportion with parental obesity. Obesity at age four increases the risk of obesity later in life. An overweight / obese child generally have worse quality of life and are more often depressed, obesity also causes diseases such as hypertension, and diabetes. To breastfeed the child promotes its appetite control and prevents obesity. Purpose: The purpose of this study was to investigate whether enhanced interventions within the framework of regular base program during pregnancy and under the children’s first four years in women with a BMI over 25 affects weight gain / ISOBMI and lactation length. Method: The intervention study of 182children divided into an intervention group (94) and a comparison group (88). Surveys regarding the child's weight, height and dietary habits were collected and analyzed when the child was 10 months, 2.5 years and 4 years old Results: A significant difference was seen between the groups at age four, when more were overweight and obese in the comparison group. The average weight differed one kg. A trend was seen in all weight categories in which the control group weighed more than the intervention group. There was no significant difference in breastfeeding duration between the groups. Conclusion: Overweight / obese women have a greater degree of overweight / obese children. Our study shows that small interventions make a difference.

Considerando a estreita relação das propriedades físicas, químico-mineralógicas e estruturais dos solos e a variação da umidade, são relevantes as leis que regem a dinâmica da paisagem. Tal conhecimento permite entender os condicionantes à deflagração e aceleração de processos como os erosivos, de assoreamento e de inundação, associados à dinâmica de infiltração e de escoamento superficial das águas das chuvas. Nesse sentido, as características climáticas constituem importante dinâmica a partir da demanda e oferta de precipitação, da variação da temperatura, da umidade relativa do ar, da direção dos ventos e da radiação solar, associadas à morfometria do terreno. Esta pesquisa apresenta análise das aracterísticas climáticas regional e local, produção e análise de mapas temáticos relativos ao relevo, uso e cobertura do solo e termografia da superfície do terreno. Apresenta ainda os resultados de um programa experimental em laboratório e in situ, incluindo análises físicas, químicas e mineralógicas ao longo dos perfis de solo de até 3 m de profundidade, distribuídos em 11 pontos no Município de Goiânia-GO. A análise do clima indicou tendência para a antecipação do período seco no outono e de seu prolongamento na primavera. A variação no campo termodinâmico das superfícies indicou temperaturas mais elevadas segundo orientação das vertentes e cobertura dos solos. Os solos estudados são ácidos, com baixos teores de alumínio, sugerindo condição de altamente lixiviados. Em relação às propriedades mineralógicas e físicas, os solos apresentaram variações em profundidade mais expressivas para os solos situados sobre rochas granulíticas. As curvas características indicaram solos com estrutura de macroporos e de microporos e diferenças estruturais entre as amostras analisadas. A variação sazonal da umidade dos solos indicou elevado gradiente de sucção no período seco. No período chuvoso, o gradiente de sucção não foi tão elevado e a variação de umidade correspondeu ao domínio dos macroporos, exceto para o final desse período. Os solos sobre rochas granulíticas indicaram maior variação da infiltração ao longo das profundidades e, em 0,1 m de profundidade, as menores taxas de infiltração. Em agosto-setembro/2010, em 0,5 e 1 m de profundidade, observou-se os menores valores na taxa de infiltração, o que permite inferir que o papel do ar aprisionado nos poros do solo dificulta o processo de infiltração. Ao serem observadas as condições presentes nos solos dos perfis analisados e o clima atuante em Goiânia, destaca-se a necessidade do conhecimento das propriedades físico, química e mineralógica e a variação sazonal da umidade no comportamento do solo, considerando a interface solo-atmosfera. _____________________________________________________________________________ ABSTRACT
Considering the close relationship of the physical properties, chemical, mineralogical and structural and soil moisture variation, it is important to consider the laws that govern the dynamics of landscape. This knowledge allows us to understand the origin and acceleration of processes, such as erosion, flooding and sedimentation, associated dynamics of infiltration and stormwater runoff. In this sense, climate characteristics are important dynamics of supply and demand of rainfall, variation of temperature, relative humidity, wind direction and solar radiation, associated with morphometric parameters of the terrain morphology. This research presents analysis of regional and local climate characteristics, production and analysis of thematic maps of morphology, soil cover and surface thermography. It also presents the experimental program carried out in the laboratory and in situ, chemical and mineralogical analysis along the soil profiles up to 3 m deep, more than 11 points in Goiânia-GO. The climate analysis indicated a trend for anticipating the dry season in the fall and extension spring. The variation in the field of thermodynamic surfaces indicated higher temperatures second orientation of slopes and land cover. The soils are acidic, with low levels of aluminum, suggesting highly leached condition. Regarding the physical and mineralogical properties, the soils had more expressive variations in depth for soils located on granulitic rocks. The characteristic curves indicated soil structure with macropores and micropores and structural differences between the samples. The seasonal variation of soil moisture showed high suction gradient in dry season. In the rainy season, the gradient was not as high suction and moisture variation corresponded to the area of macropores, except for the end of that period. The soils on granulitic rocks showed greater variation of infiltration along the depth and 0.1 m depth, the lowest rates of infiltration. In agosto-setembro/2010 0.5 and 1 m was observed at lower infiltration rate values, which we infer that the role of the air trapped in the pores hinders the process of infiltration of the soil. By being subject to the conditions present in the soils and climate of the profiles analyzed active in Goiania, highlights the need for knowledge of the physical, chemical and mineralogical and seasonal variation of moisture in the soil behavior, considering the soil-atmosphere interaction.

If the one-parent families do not form a juridic category, newtheless they are apprehended by the law. The law takes them in consideration as a sociologic reality (the one-parent families in society) or through their children (the one-parent families children). The one-parent families are treated as a sociologic reality by social law (child in charge, isolated parent allowance, familial supporting allocation) or by fiscal law. They are apprehended through their children by civil law, that it is filiation of children of one-parent family or of the position of the children in the family (patronymic name and parental authority). To express in law a sociologic reality doesn't go without difficulty, and the expected results are not always reached. On the contrary, treating one-parents families through their children shows the flexigibility of a common law wich can adapt to factual situation, always multiple and changing

Virtual Screening (VS) is a computational technique used in the drug discovery process to select the most promising candidate drugs for in vitro testing from millions of chemical compounds. This method can offer an efficient alternative to reduce the cost of drug discovery and platform. The Natural Products Chemistry Institute of the Academy of Sciences of Vietnam (INPC) collects samples from local biodiversity and determines the 3D structure of single molecules. Their challenge is to set up a virtual screening platform on grid computing for their chemists to process their data. However, as the number of users who might have a wide range of virtual screening applications (in terms of the number of tasks and execution time) increases with limited available computing resources, it becomes crucial to devise an effective scheduling policy that can ensure a certain degree of fairness, user satisfaction and overall system throughput. In this context, the thesis focuses on an effective scheduling policy for the virtual screening workflow where multiple users with varying numbers of tasks are actively sharing a common system infrastructure. We have researched in theory and proposed some candidate policies. With the simulation results and the experimentation results in real system, we proposed the best policy for the fairness between users, which can be applied to INPC virtual screening platform

Photoelectron Circular Dichroism (PECD) is observed as a forward/backward asymmetry, with respect to the photon axis, of the photoelectron angular distributions resulting from the circularly polarized light-induced photoionization of gas phase pure enantiomers of chiral species. This thesis is devoted to the study, with the synchrotron of the DESIRS beamline, of this phenomenon on different chiral systems from free molecules (bromine compounds, alanine) to glycidol clusters and water-glycidol complexes. Chapter 1 introduces the fundamental concepts required for the study of chirality in physics and chapter 2 presents the experimental and theoretical methods which have been used. Chapter 3 gives details concerning the results on the halogenated chiral compounds: bromopropionic acid (BPA) and 1,3- and 1,4-bromo-phenylethylamine isomers (BrPhEtA). The sensitivity of PECD to isomerism as well as the role of the localization of the initial orbital of the outgoing electron with respect to the chiral center is at the core of this study. The PECD of the simplest proteic chiral amino acid, alanine, produced by resistive heating and thermodesorption of an aerosol, is introduced in chapter 4 with a conformational study depending on temperature, leading to a plausible conformer distribution. These results are then discussed in the context of homochirality of life (i.e. the fact that only L-amino acids are found in the biosphere) as PECD is an asymmetric photophysical processes which can induce an enantiomeric enrichment. Chapter 5 is focused on PECD in systems of greater complexity: glycidol clusters and water-glycidol complexes. A simple mass selection enables to unravel a spectacular clustering effect on the observed PECD and the use of DELICIOUS 3 enables then to remove any cascading processes thanks to a size selection of nascent species

This thesis describes a speaker-independent isolated word recognition system which does not require any vocal training phase. The system is based on a phonetic approach which allows each phoneme to be represented by a spectral codebook. A clustering algorithm was used to build phonetic codebooks from a manually segmented and labelled multispeaker database. The training phase only consists in introducing the vocabulary words in phonetic form via a keyboard. Each word is represented by a production model in which each state corresponds to a phoneme pronunciation. A phoneme average duration is associated to the state. During the recognition phase, a global distance between the unknown word and each model is evaluated using dynamic time warping. This algorithm permits to find the best state sequence that minimizes the cumulated distances between spectral vectors of the unknown word and the reference model states

Enquadramento: Com o decorrer dos anos, fruto das alterações verificadas nas estruturas que participam na produção de fala, a qualidade vocal do indivíduo altera-se, com impacto ao nível dos parâmetros acústicos. Objetivo: Este estudo tem como objetivo determinar a influência da idade, do género e do tipo de vogal na variação dos parâmetros acústicos (frequência fundamental (F0), primeiro formante (F1), segundo formante (F2) e duração) das vogais orais produzidas por idosos falantes do Português Europeu (PE). Método: Os dados utilizados foram recolhidos pela Microsoft Language Development Center (MLDC) através da campanha “Doar a Voz”. Da amostra selecionada fazem parte 78 informantes com idades compreendidas entre os 60 e os 90 anos, divididos em seis grupos de acordo com o género e a faixa etária. Foram analisadas todas as vogais em posição tónica e contexto de oclusivas e fricativas. As palavras que continham as vogais alvo foram anotadas manualmente no Praat e os parâmetros em análise foram extraídos de forma semiautomática. Resultados: Em relação à idade, verificou-se que a duração é o único parâmetro que varia de forma significativa com o aumento dos anos, sendo os seus valores superiores nos indivíduos de [81-90] anos. No que concerne ao género, todos os parâmetros, exceto a duração, revelaram diferenças estatisticamente significativas, sendo os valores de F0, F1 e F2 superiores no género feminino. Os parâmetros acústicos também variam significativamente em função da vogal, permitindo distingui-las entre si. O F1 e o F2 são os que melhor permitem essa diferenciação. Quando comparados os resultados obtidos para os idosos com os referidos na literatura para os adultos do PE, observou-se que a F0 diminuiu no género feminino e aumentou no género masculino, com o envelhecimento. Quanto ao F1, observou-se um aumento generalizado nos idosos de ambos os géneros. Por outro lado, F2 aumentou nas vogais posteriores e diminuiu nas vogais anteriores. Em relação à duração, esta foi inferior nos idosos comparativamente aos adultos. Conclusão: Os resultados obtidos neste estudo evidenciam que os parâmetros F0, F1, F2 e duração variam com o envelhecimento. No entanto, o impacto da idade é diferente em cada parâmetro.
Background: With aging the vocal quality of the speaker changes due to speech production structural changes affecting the acoustic parameters. Objective: The goal of this study is to determine the influence of age, gender and type of vowel in the acoustic parameters (fundamental frequency (F0), first formant (F1), second formant (F2) and duration) of the vowels produced by elderly speakers of European Portuguese. Method: The data used was obtained by Microsoft Language Development Center (MLDC) through “Doar a Voz” campaign. The selected sample is composed by 78 speakers between 60 and 90 years old, the sample was divided into six groups according to their gender and age. All the vowels in stressed position and in plosive and fricative context were analysed. The words with target vowels were manually annotated in Praat and the parameters under analysis were semi-automatically extracted. Results: Regarding the age, it was observed that duration is the only parameter that significantly changes with aging, the higher value was obtained for the age of [81-90]. Concerning the gender, all the parameters, except duration, present statistically significant differences, the maximum values for F0, F1 and F2 was observed in females. Moreover, the acoustic parameters also change significantly with the vowel, allowing to distinguish between them. F1 and F2 are those which best allow this differentiation. Comparing the results obtained with the ones referred in the literature for adult speakers of European Portuguese, F0 reduces for females and increases for males with aging. On the one hand, it was verified that F1 generally increases with aging. On the other hand, F2 only increases for back vowels, whereas, for front vowels, F2 decreases with aging. The comparison also reveals that duration is lower for elderly speaker than for adult speakers. Conclusion: The results of this study show that the parameters F0, F1, F2 and duration change with aging. However, the impact of the age is different in each parameter.
