Adaptive antenna arrays can increase the capacity of wireless mobile communication systems by reducing cochannel interference. This thesis reviews current base station technology and examines the possibility of implementing an adaptive phased antenna array at a cellular CDMA base station. It is seen that a computationally simple beamforming system and direction-of-arrival estimator can signific...

Most robot platforms operate in one of two modes: full autonomy, usually in the lab; or lowlevel teleoperation, usually in the field. Full autonomy is currently realizable only in narrow domains of robotics—like mapping an environment. Tedious teleoperation/joystick control is typical in military applications, like complex manipulation and navigation with bomb-disposal robots. This thesis descr...

This thesis introduces models for error-prone communication channels and functionalities for error-free communication in the Universal Composability framework. Realizing these functionalities enables protocols to make use of cryptographic errorcorrecting schemes which are more powerful than classical codes. First, we define new ideal functionalities TrCLOSE and FCWT to model error-prone communi...

The thesis seeks a better understanding of liquidity generation process of financial markets and attempts to find a quantitative measure of market liquidity. Various statistical modeling techniques are introduced to model order flow generation, which is a liquidity generation process of the market. The order flow model successively replicates various statistical properties of price returns incl...

The goal of this thesis is to account for distributional patterns of given and new items in Czech, especially their word order. The system proposed here has four basic components: (i) syntax, (ii) economy, (iii) interpretation, and (iv) reference set computation. The approach belongs to the family of interface driven approaches. The syntactic part of the thesis introduces a free syntactic movem...
