Space- Time block codes with low maximum likelihood decoding complexity and large coding gain
Space-time block coding has been an extensively researched technique to combat multipath fading in multiple-input, multiple-output (MIMO) systems when the channel-state information is available at the receiver but not at ... -
Theoretical study of surface wave characteristics of a circular cyclindrical conductor coated with 2 graded dielectric layers embeoded in isotropic & anisotropic media
The study investigates a cylindrical conductor coated with two dielectric layers, both having radially varying dielectric constants, and the external medium being lossless, either: (a) Isotropic, or (b) Anisotropic The ... -
Non linear vibrations of stretched strings
The viscosity of pure Freon-12 and Freon-22 vapours and their mixtures has been determined by an oscillating disc viscometer at room temperature and pressure. The results agree well with the published data for the pure ... -
Measurements of the ionsation current Growth and the ratio of Diffusion coefficient to mobility for electronics in feebly Attaching gases
For a proper understanding of the mechanism of breakdown in gases, it is essential to have knowledge of the swarm coefficients, namely, the sparking potentials (V?), Townsend's primary (?/N) and secondary (?) ionization ... -
On calculation of corona and breakdown voltages of gaseous insulation with special reference to elecrro-negetive gases and their mixtures
In the design of any insulation system, mechanical, electrical, thermal, and economic considerations are generally of prime importance, and many factors contribute to the type of insulation used in a particular system. In ... -
Gaseous breakdown below paschen minimum in ExB fields
Some investigations about the electric discharge in a coaxial geometry electrode are explained in the transition range, namely, Townsend–Penning discharge for the dry air. The existing theory of 0.05 to 0.3 Torr is extended ... -
Rise and delay time of a vaccum gap triggerd by an exploding wire
Detailed investigations on the rise time (t?) and delay time of a vacuum gap employing an entirely new type of trigger mode using an exploding wire have been reported in this thesis for the first time. A large quantity of ... -
Pattern recognition via Fuzzy set methods
The main objective of this thesis is the development of a methodology based on fuzzy set theory for several practical pattern recognition problems. Pattern recognition (PR) encompasses a range of problems from feature ... -
Modelling program dynamics : A study on locality of reference
Locality of reference is a phenomenon exhibited by programs and computer systems in general, and refers to the tendency to localize operations to a small subset of the available resources. In the past, this phenomenon has ... -
