Movement Analysis of Video Footage of Patients During Epileptic Seizure

Tato práce se zabývá možnostmi automatizované analýzy pohybu pacienta, který prodělává epileptický záchvat, aby bylo možné objektivně určit vývoj nemoci. V teoretické části rozebereme existující způsoby trasování částí lidského těla a objektů v obraze a jejich použitelnost pro případ videozáznamu snížené kvality. Praktická část se zabývá návrhem algoritmu pro zpracování polohových dat sledovaného objektu a řešením v případech, kdy sledování selže. Návrh bude dále implementován v prostředí Matlab a ověřován nejprve na ideálních testovacích videozáznamech a později na skutečných záznamech dlouhodobě hospitalizovaných pacientů s epilepsií.This thesis deals with various methods of automatized analysis of a patient having an epileptic seizure for objectively define state of the illness. In theoretical part we discuss existing methods of tracking human body parts in a video and whether they are usable for our case. Practical parts introduces an algorithm propose for processing positioning data of a tracked object and solution for tracking failures. Algorithm will then be implemented in Matlab software and tested by variety of videos, starting with single simple movements and ending with real recordings of long-term hospitalized patients

Memory Consistency and Cache Coherency in Network-on-Chip Based Multi-Core Systems

The complexity of modern Systems-on-Chips (SoC) is increasing with technology innovations. Designers of such systems are devoting significant attention not only to computation attributes, but increasingly more and more on communications characteristics. Having in mind scalability challenges, Networks-on-Chip (NoC) are already de facto standard for the communication backbone of SoC systems. As such, those systems are targeting more and more parallel execution of user defined, real-time applications, but the computer engineering society aims at hiding underlying platform specific characteristics and providing user with platform-independent services. Shared memory services are quite often a needed crucial property of such systems, therefore providing a coherent view, ensuring memory consistency, and still achieving the desired performance system characteristics is a huge challenge for scientists nowadays. With the invention of 3D integration, and opportunities of stacking memory modules on top of it, the concept of scalable shared memory will be one of the main memory access concepts besides message passing. In this thesis, the concept of a scalable coherency protocol which dynamically adopts to inputs of system and shared resources, is presented. Protocol ingredients, structure and internal modules interaction are described in detail. The conceptual idea of this protocol, influenced by widely accepted best practices in bus based systems as well of other NoC systems, is implemented for one particular type of NoC platform - XhiNoC (extendable Hierarchical Network-on Chip). The feasibility of the presented concept for distributed shared memory (DSM) coherency within NoC-based SoC architectures is confirmed by simulation-based experimental results.The complexity of modern Systems-on-Chips (SoC) is increasing with technology innovations.

Prognostička valjanost informiranosti o međuljudskim odnosima za ponašanje radnika

Effectiveness of the knowledge of interpersonal relations of the managerial staff was tested on 12 supervisors in a textile factory. The supervisors were held a 7-day course in human relations and underwent a knowledge test of human relations immediately before and after the course. Besides, workers\u27 daily estimate of their supervisors\u27 behaviour was recorded in full anonimity through 50 consecutive days prior to the cou:se and 50 days after the course. Analysis of the results obtained confirmed the starting hypotheses: 1. Supervisors\u27 knowledge of the principles and facts of good human relations was considerably greater after the course. 2. Supervisors\u27 actual behaviour estimated on the basis of the ratings given by their workers did not appreciably change. S. No significant correlation was found between the changes in supervisors\u27 knowledge of interpersonal relations and the changes in their actual behaviour.Ispitivanje je provedeno u cilju da se ustanovi kakva je efikasnost izobrazbe rukovodilaca o međuljudskim odnosima. Dvanaest poslovođa jedne tekstilne tvornice pohađalo je sedmodnevni seminar iz međuljudskih odnosa. Neposredno prije, a isto tako i poslije seminara, ispitano je pomoću jednog testa znanja njihovo poznavanje principa i činjenica o odnosima medu ljudima. Osim toga, organizirano je jedno svakodnevno višemjesečno ocjenjivanje tih poslovođa, koje su vršili njihovi radnici. Svakog dana, na kraju radnog razdoblja, radnici su anonimno ocjenjivali svog poslovođu i to ocjenjivanje započelo je 50 dana prije seminara i trajalo je neprekidno do 50 dana iza·seminara. Analiza rezultata potvrdila je polazne hipoteze: 1. Poznavanje principa i činjenica o odnosima među ljudima značajno je više nakon seminara. 2. Stvarno ponašanje poslovođa, procijenjeno na temelj u ocjena njihovih radnika, nije se značajno izmijenilo. 3. Nije utvrđena, značajna korelacija između promjena u znanju poslovođa o međuljudskim odnosima·i promjena njihova stvarnog ponašanja. Na temelju dobivenih rezultata može se zaključiti da znanje koje rukovodioci stječu na seminarima o međuljudskim odnosima ne mora nužno utjecati na promjenu njihova stvarnog ponašanja u realnoj situaciji. To je, vjerovatno, zbog toga što se to znanje usvaja na jednoj racionalnoj osnovi, a u osnovi stvarnog ponašanja često leže emocionalni momenti
