Application for manual word alignment
Sochna, Jan ; Raab, Jan (referee) ; Pecina, Pavel (advisor)
The aim of this work was to design and implement platform-independent fast, flexible and user friendly interface for manual word alignment of bilingual texts. The new interface does not have the imperfections of existing similar tools and improves the performance of manual alignment process. It provides eg. half automatic alignment of simple texts, group operations with alignments, alignment of phrases, enables to shift one sentences along the line to improve the transparency of the alignment process in case that the length of aligned sentences differs substantially. The preceding and succeeding context of currently aligned sentences is shown in both the languages. Last but not least the tool provides the alignment performance statistics. Along with usual "row view", where the two sentences are shown in parallel in two rows, one above the other, being aligned by connections of corresponding words, there were introduced also a "matrix view", where the words in one language stand in for matrix line descriptors, the words in other language stand in for column descriptors and the alignment of two corresponding words is expressed by highlighting of the point of intersection of row and column with corresponding descriptors. It is possible to switch between the both views anytime during the alignment process.

Seminatural spawning of brook minnow
FIDLER, Petr
The main subject of this experiment was to explain the behaving of the minnow during its reproduction, the preferation of the spawning substratum, the length of the incubation of eggs, the evolution and the growth of the juvenile and the fry. Brood fish were taken by elektrical unit in the Blanice river, in the area between the railway bridge and the weir in the village of Blanice. These were put into the experimental pond of 75 square metres. There were two spawning processes. The first took place on 10 June , the fry hatched after ten days and in the next ten days it could be found all over the pond looking for food. In the selection of the substratum the gravel (of the size of 2-5cm) was prefered at all. The standard length of the fry at the end of the process of breeding (after a hundred days) was 39{--}48 mm (the amount of 800 individuals). The second spawn took place on 11 August. The fry hatched after eight days and the next week it was hidding in the substratum and consuming yolk sack. The standard length at the end of the breeding was 18{--}26mm. The ammount of the breeded fry was 350 individuals.

Measuring depths and lengths with a Mobile phone
Stach, David ; Ondreička, Matúš (referee) ; Matas, Jiří (advisor)
The master thesis focuses on creating of the application for some of mobile platforms (Windows Mobile Professional was chosen), which automaticaly and efectively detects deformed rectangular object on the picture and provides to transform picture into rectangular coordinates and to measure size and distance of an objects thanks to known size of objec. The application has to use algorithms, which will enable fast work of required object detector and subsequently fast transformation of whole picture. Hough transformation was chosen as a base for object detection. Design and creation of user interface is part of work too

Ichthyologic monitoring the flow of Popelka in Nová Ves nad Popelkou
ZELENKA, Václav
The aim of this work is to evaluate ichtyofauna in the stream Popelka, to determine the species composition of fish stoce and to determine the dominant fish species, their abundance and size variability. Throughout the length of the flow, twelve catching sites were identified there, the length of each site was about 50 m, the catch in these sites was from the bottom of the upstream towards the end. The catch of the flow was by wade manner with use of an electric aggregate. All caught fish species were subsequently determined. Also the body lenght so-called ?standart lenght? was measured. After measuring all fish that were caught were gently given back to the place of the catch. In terms of abundance the most numerous species in Popelka was brown trout represented by 477 subjects followed by stone loach with 391 subjects. These species clearly dominated in Popelka. Another occurring species were rainbow trout with 49 subjects, brook charr with two subjects and hybrid of brown trout and brook charr with one subject. With regard to the regional constance the brown trout was a species almost always present, with presence in 11 out of the 12 sites. Stone loach with incidence in 8 locations was mainly occurring species. With the appearance in 5 localities the rainbow trout was frequently occurring species. Among the species that are rare in Popelka, there were brook charr occurring in two locations and hybrid of brown trout and brook charr with the appearance in one location. Index of species diversity by Shannon and Wiener for the flow of Popelka is 0.88 and evenness is 0.55. Size variability across the flow in body length of brown trout was ranging from 46 to 308 mm, in diameter 126.4 mm, the stone loach from 41 to 130 mm, in diameter 80.1 mm, the rainbow trout from 65 to 250 mm, in diameter 88.7 mm and brook charr from 290 to 313 mm with an average of 301.5 mm. In the Popelka stream with a total length of 12 km there are four species of fish in these fish communities. Species diversity is distinctly poorer in comparison with the other streams. It would be appropriate to repeat the catch in the future to determine the stability of fish population in Popelka stream.

Evaluation of the sensitivity of fingers at a group of physiotherapists
Grabcová, Miroslava ; Malá, Jitka (referee) ; Nováková, Tereza (advisor)
Evaluation of the sensitivity of fingers at a group of physiotherapists Objectives: The main objective of this study is to evaluate the sensitivity of the hand, specifically stereognosis and two-point discrimination, with groups of ten physiotherapists and ten participants in the control group of normal population and to identify which of these groups will have a better sensitivity of the hand and fingers. Another objective is to compare the results with the age of all participants and with length practice of physiotherapists. Methods: I used a few simple tests for two-point discrimination (two-point discrimination test) and stereognosis (shapes of objects and their material) to evaluation of sensitivity of fingers for research subjects. The results of a professional group I statistically compared with the results of control group, which was selected from the general population. Results: The results of the first type of sensation, stereognosis, were by a group of physiotherapists in comparison with the control group significantly improved. Individual times of physiotherapists were from the first order of best to the last of the worst always smaller than in the same order in the general population. In results of the second type of sensitivity, two-point discrimination, wasn't a group of...

The role of the radiologist assistant in brachytherapy
Jašková, Ivana ; Malinová, Běla (referee) ; Kindlová, Anna (advisor)
The thesis deals with the description of the role and procedure of a radiographer at individual types of brachytherapeutical applications. It summarizes the history of brachytherapy, its division according to the localization of the source of ionizing radiation, according to the length of irradiation and the dose rate of the source. It describes the principle of both manual and remote afterloading, it indicates the sources of ionizing radiation and used values and units. It deals with individual types of brachytherapy - interstitial, intracavitar, intraluminal and surface ones, describes their application at existing types of tumour diseases and specifies the workload of particular members of brachytherapeutical team at applications.

Estrogens in environment, their impact on male fertility
Daniel, Michal ; Heráček, Jiří (advisor)
Build-up of estrogen and other endocrine disruptors in our habitat has been recently an issue widely debated not only amongst health professionals but also by main stream media. Their impact on wild animals has been observed and documented for some time now and several studies on rodents and other mammals have demonstrated a highly probable connection between exposure in early stages of development to endocrine disrupting chemicals and abnormal sexual maturation of males (hypospadia, cryptorchism), as well as impaired male reproductive functions. Epidemiological studies have been claiming significant drop in sperm count and quality of spermatozoa in last several decades, increased incidence of testicular cancer, which is being among other causes attributed also to pooling of endocrine disruptors in the environment. This reasoning brings a lot of controversy since the respective chemicals are by-products of substances commonly used in agriculture and industry and replacing them is expensive and logistically challenging. It is also quite difficult to determine and quantify the long term effects of specific chemicals on human body since the population is being exposed to not just one substance but to a whole cocktail of them and the symptomatology is subjected to age, length of the exposure, quantity of the...

Differential interferometry with suppression of the influence of refractive index of air for nanometrology
Holá, Miroslava ; Číp, Ondřej ; Hrabina, Jan ; Buchta, Zdeněk ; Lazar, Josef
We present an interferometric technique based on differential interferometry setup for measurement in the subnanometer scale in atmospheric conditions. The motivation for development of this ultraprecise technique is coming from the field of nanometrology. The key limiting factor in any optical measurement are fluctuations of the refractive index of air representing a source of uncertainty on the 1*E-6 level when evaluated indirectly from the physical parameters of the atmosphere. Our proposal is based on the concept of overdetermined interferometric setup where a reference length is derived from a mechanical frame made from a material with very low thermal coefficient on the 1*E-8 level. The technique allows to track the variations of the refractive index of air on-line directly in the line of the measuring beam and to compensate for the fluctuations. The optical setup consists of three interferometers sharing the same beam path where two measure differentially the displacement while the third evaluates the changes in the measuring range acting as a tracking refractometer. The principle is demonstrated on an experimental setup and a set of measurements describing the performance is presented.

Effect of high temperature and water shortage stresses duration during anthesis on the selected winter wheat yield formation components
Hlaváčová, Marcela ; Rapantová, Barbora ; Surá, Kateřina ; Klem, Karel ; Hlavinka, Petr ; Trnka, Miroslav
The aim of this study was to assess the effect of drought and high temperatures on Tobak winter wheat variety during one of the most sensitive developmental stage (anthesis) from the viewpoint of harvest index (HI) and spike productivity (SP). The 5 growth chambers (where the plants were exposed to these stress factors) were used for these purposes. The various protocols consisting in photosynthetically active radiation (PAR) course, relative air humidity (RH) and daily temperature courses were run. The plants were divided into 2 groups within each growth chambers: (1) Drough-stressed (Dry) and (2) well-watered (Wet). Two lengths of stresses duration were tested: 3 and 7 days. The plants were exposed to ambient weather conditions up to the full maturity after stresses exposition within the growth chambers. Subsequently, the plants were harvested manually and HI and SP were evaluated. The statistical analyses showed that the effect of each stress factor separately was statistically significant both for HI and SP14, nevertheless, these two factors interaction was statistically significant only in the case of HI.
