Dolování v prostřední MS SQL pomocí inkrementálních algoritmů / Datamining in MS SQL Using Incremental Algorithms

David, Lukáš January 2012 (has links)
This work deals with issues in data streams mining which nowadays is a very dynamic area in information technology. The thesis describes the general principles of data mining. There are also the principles of data mining in the data streams. Special attention is given to the implemented algorithm CluStream. In the practical part the data stream processing solution was designed and implemented by the MSSQL technology using the above algorithm. The functionality of the algorithm was verified using own data stream generator.

Porting DotGNU to Embedded Linux

Stein, Alexander 09 June 2008 (has links)
Programming PLC systems is limited by the provided libraries. In contrary, hardware-near programming needs bigger efforts in e. g. initializing the hardware. This work others a foundation to combine advantages of both development sides. Therefore, Portable.NET from the DotGNU project has been used, which is an implementation of CLI, better known as “.NET”. The target system is the PLCcore-5484 microcontroller board, developed by SYS TEC electronic GmbH. Built upon the porting, two variants to use interrupt routines withing the Portabe.NET runtime environment have been analyzed. Finally, the reaction times to occuring interrupt events have been examined and compared.:Contents List of Tables iv List of Figures v Listings vi 1 Introduction 1 1.1 Objective 1 1.2 Structure 2 2 State of the Art 3 2.1 .NET Framework 3 2.1.1 Common Language Runtime 4 2.1.2 Common Type System 6 2.1.3 Common Language Specification 6 2.1.4 Common Intermediate Language 7 2.1.5 Metadata 8 2.1.6 .NET Class Library 8 2.2 DotGNU 9 2.2.1 Hans-Boehm Garbage Collector 10 2.2.2 Foreign Function Interface 11 2.2.3 Interpreter 11 2.2.4 Unrolled Assembler Code 12 2.2.5 JIT Support 13 2.2.6 Debugging 14 2.2.7 X11 Support 16 2.2.8 Embedded Engine 16 2.3 Mono 17 2.4 Rotor 27 2.5 Coldfire vs. m68k 17 2.5.1 Exclusive Instructions 18 2.5.2 Floating Point Size 18 2.5.3 Other Differences 19 2.5.4 ABI Changes 19 3 Implementation 20 3.1 Incompatible m68k Code 20 3.2 Incompatible Alignments 21 3.3 Broken Toolchain 24 3.4 Unrolling Assembler Code 24 3.4.1 Setup of the Unroller 25 3.4.2 Unroller Implementation 26 3.4.3 m68k Specifics 27 3.4.4 Macro Counting 28 3.4.5 Extended Testsuite 29 3.4.6 Floating Point Remainder 34 3.4.7 Big Endianess 34 3.4.8 NOP is not just no Operation 36 3.4.9 Caches 36 3.5 C# Debugging 37 3.6 Interrupt Access in C# 38 3.6.1 Kernel Module 39 3.6.2 C# Application 40 3.7 Results 42 4 Performance 43 4.1 Portable.NET Benchmark 43 4.2 Benchmark Results 44 4.3 Interrupt Response Time 46 5 Final Remarks and Further Work 53 5.1 Conclusion 53 5.2 Improvements 53 5.2.1 Increasing Engine Performance 53 5.2.2 Tweaking IRQ Handling 54 5.2.3 Porting JIT to MCF5484 55 5.2.4 Miscellaneous 55 6 Acronyms 56 Bibliography 58 A Contents of the enclosed CD 61 / Die Programmierung für SPS-Systeme ist durch die gegebenen Bibliotheken beschränkt, während hardwarenahe Programmierung einen größeren Aufwand durch z.B.

Análise de populações leucocitárias em doadores de plaquetas e em câmara de leucorredução. / Analysis of leukocyte populations, in platelet donor, and in Leukoretuction System Chamber.

Borges, Andressa de Oliveira Dias 05 December 2014 (has links)
A doação de plaquetas por aférese é um procedimento automatizado que permite a obtenção deste hemocomponente em grande quantidade e com ato grau de pureza; deste processo obtém-se um subproduto chamado Câmara de Leucorredução (CLR) que é descartado ao final da doação. São permitidas até 24 doações/ano; porém as possíveis consequências de doações frequentes para esses doadores são pouco investigadas. Assim, foram identificados e quantificados os leucócitos de doadores de plaquetas frequentes e de 1ª vez. Também foi avaliada a viabilidade do uso das células mononucleares da CLR para pesquisas. Observou-se mais células na CLR que no sangue e que a frequência das populações é similar. O estado de ativação e a capacidade funcional (proliferação e produção de citocinas) foram similares entre CLR e sangue, assim como a taxa de apoptose espontânea. Entre doadores frequentes e de primeira vez não houve diferença no número de leucócitos, sugerindo que doações recorrentes não alteraram as populações leucocitárias. / Plateletpheresis is an automatized procedure to obtain high purity platelet for transfusions. From this procedure its possible to obtain a byproduct: The Leukoreduction system chamber (LRSC), which is discarded at the end of donation process. This type of donation allows 24 donation/year, but the consequences of frequent donations are poorly investigated. Therefore, we identified and quantified leukocytes of frequent and first time platelet donor. Also, was evaluated the viability, for research, of mononuclear cells recovery from LRSC. The total number of mononuclear cells was higher in LRSC than in peripheral blood samples, but the frequencies were similar in all the samples. Activation state and functional capacity (measured by cell proliferation and cytokine production) were similar in both, blood and LRSC mononuclear cells, as well as spontaneous apoptosis. Among frequent (6 or more donations in 1 year) and first time donor, there was no difference in the leukocyte total number, suggesting that frequent donation do not modify these cells.

Due to this property these materials are widely usedin Chemical-Looping Reforming processes to produce H2 and syngas. In this work supports based on MCM-41 and La-SiO2 were synthesized by hydrothermal method. After the synthesis step they were calcined at 550?C for 2 hours and characterized by TG, XRD, surface area using the BET method and FTIR spectroscopy. The deposition of active phase, in this case Nickel, took place in the proportions of 5, 10 and 20% by weight of metallic nickel, for use as oxygen carriers.The XRD showed that increasing in the content of Ni supported on MCM-41 resulted in a decrease in spatial structure and lattice parameter of the material. The adsorption and desorption curves of the MCM-41 samples exhibited variations with the increase of Ni deposited. Surface area, average pore diameter and wall density of silica showed significant changes , due to the increase of the active phase on the mesoporous material. By other hand, in the samples with La-SiO2 composition was not observed peaks characteristic of hexagonal structure, in the XRD diffractogram. The adsorption/desorption isotherms of nitrogen observed are type IV, characteristic of mesoporous materials. The catalytic test indicates that the supports have no influence in the process, but the nickel concentration is very important, because the results for minor concentration of nickel are not good. The ratio H2/O2 was close to 2, for all 15 cycles involving the test storage capacity of O2, indicating that the materials are effective for oxygen transport / Transportadores de oxig?nio s?o ?xidos met?licos que possuem a capacidade de oxidar e reduzir facilmente por diversos ciclos. Devido a essa propriedade estes materiais s?o bastante utilizados nos processos de Chemical-Looping Reforming para a produ??o de H2 ou g?s de s?ntese (H2 mais CO). Neste trabalho foram sintetizados os suportes MCM-41 e La-SiO2 pelo o m?todo hidrot?rmico. Os materiais resultantes foram calcinados a 550 ?C por 2 horas e, posteriormente, caracterizados por TG, DRX, ?rea superficial pelo m?todo BET e FTIR. Ap?s a caracteriza??o dos suportes foi feita a deposi??o da fase ativa (Ni) com as propor??es de 5, 10 e 20% em massa de n?quel met?lico, para aplica??o como transportadores de oxig?nio. As an?lises de DRX mostraram que o aumento do teor de Ni suportado em MCM-41 deu origem a uma diminui??o no ordenamento estrutural e no par?metro de rede do material. As amostras MCM-41 apresentaram varia??es quanto ?s curvas de adsor??o/dessor??o de nitrog?nio, ?rea superficial, di?metro m?dio de poros e espessura da parede de s?lica, em fun??o do aumento da fase ativa no material mesoporoso. Enquanto que nas amostras com La-SiO2 n?o se observou picos caracter?sticos da estrutura hexagonal, nos difratogramas de DRX. Entretanto, as curvas de adsor??o/dessor??o de nitrog?nio observadas s?o do tipo IV, caracter?stico de materiais mesoporosos. Os resultados dos testes dos transportadores indicam que o suporte n?o influenciou no processo catal?tico. A raz?o H2/O2 foi pr?xima de 2, durante todos os 15 ciclos envolvendo o teste de capacidade de armazenamento de O2 , indicando que os materiais s?o eficientes para o transporte de oxig?nio estrutural e no par?metro de rede do material.
