Abstract:
The aim of the project was to synthesize linear anthrasteroid analogues of testosterone, 19-nortestosterone and estradiol. A total synthesis of (+/-)-7,11-cyclo-8,9-seco-19-nor-testosterone, (+/-)-7,11-cyclo-8,9-secoestradiol and (+/-)-1beta-t-butoxy-9a,11abeta-dimethyl-1,2,3, 3aalpha, 4, 4aalpha, 5,8,9, 9a,10,10alphabeta,11,11a-tetradecahydro-7-cyclopent[b]anthrac-enone was accomplished. The synthesis presented provides a short, direct route to linear anthrasteroid analogues. This compares favourably with the synthesis reported by S. Aoyama and K. Sasaki, which involves complex transformation

Abstract:
Applications such as satellite and digital mobile radio systems (DMR) have gained widespread acceptance in recent years, and efficient digital processing techniques are gradually replacing the older analogue systems. An important subsystem of these applications is voiceband communication, especially digital speech encoding. Digital encoding of speech has been a focus of speech processing research for many years, and recently this activity together with the rapid advances in digital hardware, has begun to produce realistic working algorithms. This is typified by the Pan-European DMR system whic

The mathematical formulation of various control synthesis problems (such as Decentralized Stabilization Problem (DSP), Total Finite Settling Time Stabilization for discrete time linear systems (TFSTS), Exact Model Matching Problem (EMMP), Decoupling and Noninteracting Control Problems) via the algebraic framework of Matrix Fractional Representation (MFR) - i.e. the representation of the transfer matrices of the system as matrix fractions over the ring of interest - results to the study of matrix equations over rings, such as : A .

Abstract:
Conventionally, the problem of plan formation in Artificial Intelligence deals with the generation of plans in the form of a sequence of actions. This thesis describes an approach to extending the expressiveness of plans to include conditional branches and recursion. This allows problems to be solved at a higher level, such that a single plan in such a language is capable of solving a class of problems rather than a single problem instance. A plan of fixed size may solve arbitrarily large problem instances. To form such plans, we take a deductive planning approach, in which the formation of th

Markov jump linear systems find application in many areas including economics, fault-tolerant control, and networked control. Despite significant attention paid to Markov jump linear systems in the literature, few authors have investigated Markov jump linear systems with time-inhomogeneous Markov chains (Markov chains with time-varying transition probabilities), and even fewer authors have considered time-inhomogeneous Markov chains with a priori unknown transition probabilities.

Nonlinear dynamical systems are of wide interest to engineers, physicists and mathematicians, and this is due to the fact that most of physical systems in nature are inherently non-linear.

Chaotic systems are striking examples of this. In most cases, there are no hard and fast rules to analyse these systems.
