Telecommunication Circuits and Technology
Communication systems consist of an input device, transmitter, transmission medium, receiver and output device, as shown in Fig. 1.1. The input device may be a computer, sensor or oscillator, depending on the application of the system, while the output device could be a speaker or computer. Irrespective of whether a data communications or telecommunications system is used, these elements are necessary.

Security of Digital Enhanced Cordless Telecommunication (DECT) devices for residential use
The Digital Enhanced Cordless Telecommunication (DECT) standard provides voice, data and networking applications; currently there are about 31.5 million DECT devices only in Germany. Attacks and new analysis methods were published on www.dedected.org in 2008. In this thesis DECT devices of different manufacturers were analysed with the help of the named methods; due to that it was firstly possible to deliver insight into the current security status of DECT devices for residential use. The amount of implemented security mechanisms as recommended by the European Telecommunication Standard Institute (ETSI) is revealed through these examinations. Finally this thesis arrives to the conclusion that none of the tested devices provides a global protection of authenticity and privacy.

Mikrobiologiyadan amaliy mashg`ulotlar
«Mikrobiologiya» fani egallagan soha juda keng bo‘lib, uni o‘quvchiga to‘liq yetkazish uchun bir necha qismga bo‘lib o‘rganiladi. Birinchi qismda — mikro organizmlar morfologiyasi va fiziologiyasi, ularning tabiatda tarqalishi haqida umumiy ma’lumotlar berilgan. Xususiy mikrobiologiya qismida yuqumli kasalliklarni qo‘zg‘atuvchi mikroorganizmlarning barcha xossalari o‘rganiladi. Darslikda asosiy e’tibor mikrobiologiya amaliyotida bajariladigan laboratoriya mashg‘ulotlariga qaratilgan.

Treck geometry for high-speed railways
The present work consists of two main parts. The first part (Chapter 2 and 3) deals with a literature survey where a short introduction is given for track geometry and track/vehicle interaction. After the introduction, a survey over the present standard in Europe and Japan is made. In particular the recent proposals for a common European Standard (CEN) and TSI (Technical Specification for Interoperability) are reviewed. The second part (Chapter 4, 5 and 6) starts with an attempt to foresee the performance of a train that would be available from the industry around 2010. Furthermore, the second part deals with simulations. Firstly, hunting stability is simulated to establish a vehicle configuration that could deal with higher speeds. Secondly, track shift forces are simulated with Prud’hommes criteria as boundary condition. Thirdly, a risk factor for vehicle overturning was calculated in the most adverse case where the train was running on a curve and the wind was directed outwards. In the simulations, two sets of track irregularities were used.
