Nonexponential decay of sound in rooms
(i) The above analysis of decay of sound in rectangular rooms under various boundary conditions shows that the overall decay is in general non?exponential because the normal modes corresponding to different angles of ... -
Studies on the role of spatial coherena in the lau phenomenon
The Laue effect is of fundamental importance in the domain of optical interference phenomena. In the Laue experiment, interference fringes are formed in the far field when an extended source illuminates two gratings placed ... -
Relative efficiencies of devanagari and tamil scripts for reading
This thesis is devoted primarily to some of the problems involved in reading with particular emphasis on Devanagari and Tamil scripts. Scripts are considered as codes and their performance examined on the basis of information ... -
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 ... -
Model-based Deep Learning Algorithms in Mimo Receivers : Channel Estimation & Symbol Detection
With the advent of Massive multiple-input-multiple-output (MIMO) wireless communication systems, users can now enjoy high spectral efficiency and throughput leading to a better quality of service. The efficacy of these ... -
Intelligent Reflecting Surfaces for Wireless Communications: Low-Complexity Techniques and Performance Analysis
Intelligent reflecting surface (IRS), also referred to as reconfigurable intelligent surface (RIS), is an emerging technology aimed at dynamically controlling the propagation environment of next-generation wireless systems. ... -
Efficient Signal and Modulation Classification for High Mobility Wireless Communication System
The escalating demand for high-mobility applications, such as vehicle-to-everything (V2X) networks, high-speed rail, and internet of things (IoT), drives the evolution of sixth-generation (6G) wireless communication ... -
Diffusion approximation models for broadband integrated networks and their performance evaluation
In this thesis, we first consider the VBR video traffic modelling, then the reactive congestion control of VBR and BET traffic, and finally the optimal scheduling scheme for CBR traffic over the broadband integrated services ... -
Array combiner For GMRT
Today, Radio Astronomy has developed into a highly complex, interdisciplinary subject. Many radio astronomical problems need technologies from different engineering fields and knowledge from many scientific fields, at times ... -
Performance analysis of TCP connections with RED control and exogenous traffic
The Transmission Control Protocol (TCP) is the main protocol used in the Internet for data transfer applications. Certain congestion control mechanisms have been incorporated in host implementations of this protocol which ... -
Study of simulated xy plasma at k-band
Spacing between the wires (in mm) Spacing between the grid structures (in mm) Free-space wavelength (in mm) Simulated plasma frequency (in Hz) Frequency of the oscillator (in Hz) Refractive index Equivalent plasma density ... -
DPLL's for network synchronization: a new approach.
A new DPLL has been described in this thesis to overcome some of the limitations of the conventional second-order DPLL in the context of network synchronization applications. The analytical and computer simulation studies ... -
Design and development of subject storage and learner models for WESLA
With the advent of the web, the Internet has evolved into a user-friendly medium, capable of high-speed on-demand information delivery. Web-based distance learning systems support distributed and asynchronous learning. ... -
