Measurement of the vibrations
Diblík, Jan ; Kolouch, Jaromír (referee) ; Biolková, Viera (advisor)
Diploma thesis is focused on principles of measuring the vibrations using accelerometers and using them for making vibration measuring instrument with focus on modern integrated digital accelerometers. In the first part are described ways to measure acceleration and vibrations with available technical supplies with respecting place and purpose of measuring. In practical part are measured characteristics of used sensor, instrument for measuring vibrations is designed and built and for few experimental object vibrations or acceleration are measured and graphical interpreted.

Short path optical wireless link design
Kovář, Ondřej ; Látal, Jan (referee) ; Diblík, Jan (advisor)
This diploma thesis is focused on design and prototyping of wireless optical link for an indoor usage. In the beginning of the thesis frequency spectrums of infrared, visible and ultraviolet light are described by its typical qualities such as values of attenuation or reflection capability. On the basis of this analysis, a proper wavelength has been chosen for usage at the engineered communication system. Next part is devoted to selection of suitable communication components on basis of its declared qualities. In the following chapter this qualities are in carefully measured and after that they are compared with values provided by its manufacturer. The following section is devoted to design schemes of transceiver modules. After completion of the design the manufacturing of PCB, mounting components and the analysis of their distribution was described. The last part of this thesis deals with testing of created prototype in terms of maximum transmission distances and operating frequencies. At the very end of this project, in one small section ways to improve system characteristics was discussed.

Laser diode driver
Pučálka, Jan ; Látal, Jan (referee) ; Diblík, Jan (advisor)
The thesis describes the function and an energizer fount design for a laser diode.The main aim was to be familiarized with the requirements for the laser diode construction and to realize the equipment which enables an intensive modulation of a radiated cluster accompanied with a dynamics at least 80% of a maximum radiated output. The introduction of the thesis is focused on the issue of the primary features and elementary ideas concerning the matter of the laser. Moreover the types, infiltration application and the essential laser diode wiring are defined.The conclusion of the thesis is concentrated on the energizer fount linkage for the laser diode.

Electronic informative board
Kakáč, Tomáš ; Křivák, Petr (referee) ; Diblík, Jan (advisor)
This thesis dealt with concept of electronic informative board. The board is connected PC via USB. Data are converted from USB using converter to input microprocessor. These data are processed and displayed on graphic lcd display. During bachelor's thesis we're resumed with realization electronic informative board. We used a microcontroller from Atmel. Futher, we required a real-time circuit from manufacture Epson. For the imaging unit we used a graphic LCD display from copany Powertip. Following the design we compiled and revived a hardware part of the device. After a succesfull revive, we compiled a program for microcontroller. It was written in programming language C, with use of compiling enviroment AVR studio 4.

Energy labels of electrical appliances
Diblík, Jan ; Bok, Jaromír (referee) ; Drápela, Jiří (advisor)
In my bachelor's thesis I engaged in energy cards of electrical appliences. I acted and controled for Law number 406/2000Collection, for manage energy what frame preparation Czech Republic walk in European Union introduce in harmony with european legislature. This law and legislature in conjunction with law signify charge for all producer alectical appliences mention energy cards in the all appliences. I mention for example energy card. On the energy card are appliences distribute for seven energy class according to class A is the most of economy class and class G is least economy class. On the energy card mention next particulars, for example name or business symbol of producer, identity symbol of model applience use of producer or impporter and next. In my thesis I engaged progresses for determine energy class electrical appliences formation universal progresses for determine energy class appliences, define basic universal qualities and parameters. There are pieces of knowledge is possible take advantage of already non-cards appliences, determine energy classes divided for two groups. First group energy class is enumerace for consuption electric energy and second group energy class is enumerace with regard to next quantity. It was extract wrote next important and universal date on energy card. All pieces of knowledge took advantage of application energy card on non-card appliences factual home bakery of bred. At this home bakery of bred chaose reference conditions at what measured electrical consuption. I was set up energy class in what Iam put into its this consuption. For objektive was set up energy card this home bakery of bred.

Digital data recorder
Müller, Tomáš ; Skapa,, Jan (referee) ; Diblík, Jan (advisor)
This thesis deals with method of measuring optical beam intensity, searching for communication system beam using stepper motor movement of the optical head and processing measured signal for displaying on PC. The basic theory of optoelectronics is shown here concerning the problem. There is elaborated main principles of photodetector and stepper motor mainly, which are main part of device. The second part of work is theoretical design of data recorder. All parts are described individually-their characteristics and conditions for correct usage. In the last part setup of device is explained, with the references to blocks of written programs. In the last part, main funcrions of system, its hardware managing and communication are described. At the very end of thesis, examples of measured data are presented.

Analysis of chromosomal aberrations in sperm by fluorescence in situ hybridization
Bendová, Petra ; Diblík, Jan (advisor) ; Novotná, Drahuše (referee)
The presented bachelor work is focused on the determination of frequency chromosomally abnormal sperm in the semen of healthy men (donors) with normal karyotype (46, XY). The important process, which plays an irreplaceable role in the development of numerical aberrations of chromosomes or structural abnormalities in the segregation of the gametes, is meiosis. Therefore, I devote much attention on meiosis in the theoretical part. The theoretical part is focused on the process of pre mature sperm (spermatogenesis), and the consequences of fertilize the oocyte by aneuploid sperm. In my work I present an overview of numerical abnormalities in autosomes and gonosomes and their frequency and distribution of gametes in healthy men. I also focused on the distribution and a brief description of structural aberrations affecting chromosomes and not least I paid attention on method of multicolor interphase fluorescence in situ hybridization, which in combination with sperm chromatin dekondenzation become irreplaceable and valuable research tool for rapid analysis of chromosomal abnormalities in large sperm samples. The experimental part of bachelor work deals with monitoring the frequency of selected numerical abnormalities in sperm samples of five donors aged 23 to 30 years with the use of I-FISH (fluorescence in situ...
