While working on this paper I got acquainted with the methods of creating questionnaires and tests as well as the principles of question choice. Realizing the model of the testing system, I have deepened my knowledge of Visual Basic 6. in this programming language the possibilities of management of personal data bases have been extended. The questioning system allowing to create an electronic questionnaire has been developed. You can choose any number of questions in this questionnaire and a number of possible answers and answer the points in the questionnaire. This system allows to transfer the data to the bases quickly and easily. The rapidly and cost of traditional questioning has been estimated and electronical questioning system has been created.

In the contemporary world of techniques, voice technologies, such as speech recognition, synthesis of speech signals, and their combined versions, acquire more and more significance. If we had a good synthesizer, we could use it widely. An example could be the reading of electronic books in voice, etc. Speech synthesizers of older generation were quite primitive. A modern synthesis machine is not only able to read the text evenly, but to convey the emotionality as well. Speech synthesizer can raise a tone, dictate a question, and synthesize a voice of a desired timbre and speed. These features considerably enrich the speech synthesized. The articulatory speech synthesizer is based on a model of the physiology of the human speech production process. Articulatory synthesis usually consists of two separate components – articulatory model and acoustic model. In the articulatory model, the vocal tract is divided into numerous small sections and the corresponding cross – sectional areas are used as parameters to represent the vocal tract characteristics. In the acoustic model, each cross–sectional area is approximated by an electrical analog transmission line. To simulate the movement of the vocal tract, the area functions change time. The aim of the research paper is to analyze the consistent pattern of the vocal tract, generating the sound of Lithuanian language. The tasks are these: to look at the history of speech synthesis; to look at the architecture of speech; to overlook... [to full text]

Indiana University-Purdue University Indianapolis (IUPUI) / Polypharmacy leads to increased risk of drug-drug interactions (DDI’s). In this dissertation, we create a database for quantifying fraction of metabolism (fm) of CYP450 isozymes for FDA approved drugs. A reproducible data collection protocol was developed to extract key information from publicly available in vitro selective CYP enzyme inhibition studies. The fm was then estimated from the curated data. Then, proposed a random control selection approach for nested case-control design for electronical health records (HER) and electronical medical records (EMR) databases. By relaxing the matching by case’s index time restriction, random control dramatically reduces the computational burden compared with traditional control selection approaches. Using the Observational Medical Outcomes Partnership gold standard and an EMR database, random control is demonstrated to have better performances as well. Finally, combining epidemiological studies and pharmacokinetic modeling with fm database, we detected and evaluated high-dimensional drug-drug interactions among thirty high frequency drugs. Multi-drug combinations that increased risk of myopathy were identified in the FAERS and EMR databases by a mixture drug-count response model (MDCM) model. Twenty-eight 3-way and 43 4-way DDI’s increased ratio of area under plasma concentration–time curve (AUCR) >2-fold and had significant myopathy risk in both databases. The predicted AUCR of omeprazole in the presence of fluconazole and clonidine was 9.35; and increased risk of myopathy was 6.41 (LFDR = 0.002) in FAERS and 18.46 (LFDR = 0.005) in EMR. We demonstrate that combining health record informatics and pharmacokinetic modeling is a powerful translational approach to detect high-dimensional DDI’s. / 2 years

<p>Digital television is one of the biggest broadcasting media available. All over the world television companies are rearranging their broadcasting from analogue to digital transmission. Former standard disagreements in the analogue era have lead to an agreement of one common European standard for digital television. Countries like USA and Japan have their own similar standards.</p><p>The report consists of two objectives; a survey of the most commonly used standards for digital television today and the construction of a prototype receiver for the second generation satellite DVB-standard.</p><p>A thorough literature study and careful design resulted in a fully functioning system. Measurements performed on the DVB-S sections gave exemplary results. Comparing these results with corresponding measurements performed on the DVB-S2 section showed much better performance for DVB-S2 with the same code rates. This shows some of the advantages of the new standard and proving the coding theory right. New coding algorithms make it possible to transmit more information on noisier channels of inferior quality. In laymen’s words; DVB-S2 gives a better picture and more television channels on the same satellite compared to DVB-S.</p>

SANTRAUKA Nors formaliai 2002/96/EB direktyvos nuostatos yra perkeltos ir Lietuva apie tai yra pateikusi notifikaciją ES institucijoms, nebuvo įvertinta, ar kokybiškai ir tiksliai perkeltos direktyvos normos. Taip pat nebuvo įvertinta, kaip įgyvendinamos perkeltos nuostatos ir ar pasiekiami direktyvoje numatyti tikslai. Šiame darbe nagrinėjama EEĮ atliekų tvarkymo situacija Lietuvoje, vertinama 2002/96/EB direktyvos perkėlimo kokybė, identifikuojamos EEĮ atliekų tvarkymo problemos. Analizė parodo kokie nacionaliniai teisės aktai yra keistini ir kokias problemas reikia spręsti norint pasiekti direktyvoje nustatytus tikslus. IŠVADOS 1. Europos Parlamento ir Tarybos Direktyvos 2002/96/EB „Dėl elektros ir elektroninės įrangos buvo perkelta į Lietuvos nacionalinę teisinę bazę skubotai, siekiant laikytis numatytų terminų, todėl didelė dalis nuostatų perkelta pažodžiui, atkartojant direktyvos nuostatas, bet neužtikrinant jų įgyvendinimo priemonių. Yra nuostatų, kurios visai nebuvo perkeltos ar perkeltos netiksliai; 2. Dauguma Direktyvos 2002/96/EB esminių nuostatų yra perkeltos į Atliekų tvarkymo įstatymą ir Vyriausybės nutarimais, o juose nustatyti pagrindiniai reikalavimai yra tik detalizuoti kitais poįstatyminiais teisės aktais. 3. Siekiant pasiekti 2008 m. nustatytą minimalią 4 kg EEĮ atliekų surinkimo iš privačių namų ūkių užduotį būtina 28 procentais padidinti esamą surinkimą iš privačių namų ūkių, kuris šiuo metu yra apie 3,12 kg/ gyventojui.

The setting up of efficient collection schemes In Lithuania is necessary to ensure the achievement of the targets set in the Directive. Lithuania, as well as all others new members of EU, have not developed WEEE management systems and is developing new one in order to comply with the Directive. Lithuania have chosen to apply market based approach with multiple providers of take back services, apart from the collective single compliance scheme models being used in the countries with already existing systems. In this study the legal and operational approach of WEEE management system in Lithuania was analized. The mistakes made in transposition of the WEEE Directive was identified, as well as the problems arising out of implementation of the Directive requirements. The Directive states that each Member State should collect 4 kg of WEEE per capita – this target is not reached in Lithuania yet. In year 2006 the collection level of WEEE was 3.12 kg per capita. The recommendations were proposed to change the existing system in order to fulfill all requirements of the Directive.

A avaliação da classificação foi desenvolvida em duas unidades de beneficiamento de tomates de mesa, sistema de classificação eletrônica e mecânica, e em dois períodos de produção, safras de verão e inverno. O cultivar utilizado foi Carmen. Para cada safra foram realizadas três etapas: (1) Avaliar a conformidade de classificação por diâmetro e coloração dos equipamentos com sistema eletrônico e mecânico de classificação com o PROGRAMA BRASILEIRO PARA A MODERNIZAÇÃO DA HORTICULTURA (2003), (2) Verificar a conformidade de classificação por diâmetro obtida dos equipamentos, com a regulagem programada pela unidade de beneficiamento e (3) Acompanhamento da vida pós-colheita dos tomates provenientes da classificação nesses equipamentos em laboratório da Faculdade de Engenharia Agrícola ¿ UNICAMP, onde os tomates ficaram armazenados em câmara de refrigeração a temperatura ambiente de 24 ± 1ºC e umidade relativa de 75 ± 5% por um período de 20 dias. Foram realizadas análises como, perda de massa, qualidade visual, evolução da coloração, firmeza e químicas (pH, sólido solúvel, acidez titulável) e cálculo da relação sólido solúvel/acidez titulável. Dentre os resultados, não houve conformidade de classificação por diâmetro e coloração, dos equipamentos, com a norma de classificação do Programa. A conformidade de classificação obtida com a programada apresentou somente para classe de maior diâmetro, em ambos os equipamentos. Na avaliação da qualidade visual, os frutos sadios após armazenamento por 20 dias não apresentaram diferença significativa entre os equipamentos. Como razão de descarte, na safra de verão, enrugamento foi mais freqüente no equipamento eletrônico e a podridão no mecânico, na safra de inverno os descartes foram mais freqüentes no equipamento mecânico. A perda de massa foi maior no equipamento mecânico em ambas as safras. A evolução da coloração dos tomates foi mais intensa na safra de verão no equipamento mecânico e menor intensidade no inverno para o mesmo equipamento. Não houve diferenças significativas para a variação do índice de firmeza entre os equipamentos. As análises das características químicas, não foram significativas. O equipamento eletrônico apresentou melhor desempenho sobre o equipamento mecânico, em relação à classificação e na qualidade da vida pós-colheita dos frutos provenientes desta classificação. Embora utilize alta tecnologia, este equipamento deverá ser monitorado constantemente em suas atividades visando sua eficiência e viabilização do seu investimento. Pelos resultados apresentados, recomenda-se para o sistema mecânico, rever o sistema de classificação de correia de lona furada para que atenda a legislação de classificação do Programa Brasileiro para a Modernização da Horticultura, e garanta melhor desempenho nas etapas de lavagem, secagem e polimento / Abstract: The fresh market tomato industry has been evolved, in the last six years, with the implantation of tomato grade machines, electronical and mechanical equipments. Evaluation of the grading performance electronical and mechanical equipments was done at summer and winter seasons. The cultivar studied was Carmen. For each season, three main points were studied: (1) Evolution of the size and color grading conformity with the BRAZILIAN PROGRAM FOR HORTICULTURE MODERNIZATION standards. (2) Evaluation of size grading conformity with the one established by the packer. (3) Post harvest shelf life and grading quality of tomatoes during for 20 days in controlled environment at 24ºC ± 1ºC and 75% ± 5% RH, FEAGRI/UNICAMP. During storage, visual quality evaluation and physical and physical chemical analysis were done: weight loss, color evolution, firmness, pH, soluble solids, tritratable acidity and ratio. There was no grade conformity with the fresh tomato quality standards of the BRAZILIAN PROGRAM FOR HORTICULTURE MODERNIZATION. There was conformity with the grading programmed by the packer, only for large size, in both equipments. After storage for 20 days, there were not any significant statistic difference on fruit quality sorted by electronical and mechanical equipments. For summer season, the major cause for fruit discharge was shrunken fruits in electronical equipment and decay in mechanical equipment. For winter season there were high post harvest losses at the mechanical equipment. The highest weight loss was found on fruits sorted at the mechanical equipment at the two seasons. The mechanical equipment showed the most intense color evolution at summer season and the less intense at winter season. There were not statistical differences between the equipments for firmness loss. There were also not statistical differences, between the equipments for chemical analyses. The electronical equipment has presented better performance, compared to the mechanical equipment, considering grading performance and post-harvest fruits quality. Despite of its high technology the electronical equipment must be constantly monitored to achieve efficiency and return of the investment. The mechanical system must review its size grading, to achieve grade standards stablished by the BRAZILIAN PROGRAM FOR HORTICULTURE MODERNIZATION and must improve its cleaning operation / Mestrado / Tecnologia Pós-Colheita / Mestre em Engenharia Agrícola

Dans les années 2000, les matériaux de conversion sont apparus comme une alternative intéressante aux matériaux d'insertion actuellement utilisés dans les batteries Li-ion. Ils réagissent avec le lithium pour former une électrode constituée de nanoparticules métalliques encapsulées dans une matrice lithiée. Pour comprendre ces réactions, le phosphure de cobalt (CoP) a été étudié au moyen de techniques théoriques et expérimentales. La complexité de ces systèmes nanocomposites n'a pas permis de caractériser toutes les espèces présentes dans l'électrode. Cependant, les calculs DFT ont prédit la formation de composés intermédiaires dont les potentiels de formation sont cohérents avec l'expérience. De plus, ces travaux ont mis en évidence l'importance de la réactivité de surface quant à l'origine de l'hystérésis de potentiel qui nuit au rendement énergétique de ce type d'électrode. La méthodologie développée spécialement pour les réactions de conversion, mais transférable vers d'autres réaction électrochimique, a été validée par les mesures expérimentales. / In the 2000s, conversion materials appeared as an interesting alternative to the insertion materials currently used in Li-ion batteries. They react with lithium to form an electrode constituted of metallic nanoparticles embedded into a lithiated matrix. To understand those reactions, cobalt phosphide (CoP) has been studied by theoretical and experimental techniques. The complexity of those nanocomposite systems does not allow to characterize all the species present inside the electrode. However, DFT calculations predicted the formation of intermediate compounds whose the formation potentials are in agreement with the experiment. Moreover, these studies have highlighted the importance of surface reactivity about the voltage hysteresis which harms to the electrode efficiency.The methodology especially developed for conversion reactions, but transferable to others electrochemical reaction, was validated by experimental measures.

Lietuvoje, kaip ir visame pasaulyje šiuo metu, rengiant rinkimus kyla didelė problema, kurios esmė - per mažas rinkėjų aktyvumas dalyvaujant šalyje vykdomuose rinkimuose. Rinkimai vykdomi įprastiniu būdu nepritraukia visų rinkėjų, kadangi piliečiams, turintiems teisę dalyvauti rinkimuose, ne visuomet yra patogu apsilankyti rinkimų apylinkėse dėl laiko stokos ar dėl didelio atstumo iki rinkiminės apylinkės. Vienas iš galimų piliečių dalyvavimo šalies politiniuose procesuose padidinimo metodų gali būti elektroninių balsavimų sistemų kūrimas. Kadangi manoma, kad elektroninės balsavimo sistemos suteiktų papildomų patogumų rinkėjams, dalyvaujantiems balsavimo procesuose, daug pasaulio šalių stengėsi sukurti tokias sistemas ir pradėti naudoti jas šalies rinkiminiuose procesuose. Šiame darbe yra pateikti elektroninių balsavimo sistemų modelius ir kūrimą sąlygojantys aspektai, o taip pat aptariamos pagrindinės grėsmės, kurios gali įtakoti elektroninių balsavimo sistemų sklandų darbą. Darbe pateikiama medžiaga, kurioje analizuojami elektroninių balsavimo sistemų atakų metodai, o taip pat nurodomos priežastis, dėl kurių šios sistemos gali būti atakuojamos. Taip pat darbe yra analizuojama elektroninių rinkimų įgyvendinimo patirtis kai kuriuose pasaulio šalyse, o taip pat atlikta Lietuvoje patvirtintos balsavimo internetu rinkimuose ir referendumuose įgyvendinimo analizę ir aptartas galimas Lietuvos elektroninio balsavimo sistemos modelis.

Problem is that citizens are very apathetic and their participation in elections and referendums are very low. Elections and referendums which are based on traditional election system, using paper ballots, are uncomfortable for a lot of citizens, which have election right, because it’s not very comfortable or possible to reach voting poll’s on an election day. In this case the participation of citizens is very low, because it’s not always possible to visit polling stations when the distance to it is quiet big or citizen have no time to vote. This problem is very urgent in Lithuania to. One of the easiest ways to increase participation of citizens in country political processes is creation of electronical voting systems which can be used to cast citizen vote remotely or not. Because of opinion that e-voting systems will be more convenient for the voters and this will increase voters turnout on elections and referendums, governments of some countries are trying to create and begin to use those systems on their countries general elections and referendums. This paper work is representing the standards and main aspects of creation of the e-voting systems and main threats to electronical voting systems. It discusses about system attack methods and people which are interested in e-voting systems compromising. Also it analyzes the... [to full text]
