A Method of Designing Museum Services Handling System for Ubiquitous Visitors
Advances in mobile computing technologies have enabled the personal ubiquitous computing environment for ubiquitous visitors. In the case of museum services, a ubiquitous visitor is free to access his/her interested exhibit ...
Codes for distributed storage, private information retrieval and low-latency streaming
This thesis presents results on error correcting codes for settings such as: (a) distributed storage, (b) private information retrieval, and (c) low-latency streaming. It also presents two new decoding algorithms for Polar ...
Mask Estimator Approaches For Audio Beamforming
Beamforming is a family of algorithms and performs a spatial filtering operation that makes it possible to map the distribution of the sources at a certain distance from the microphones and therefore locate the ...
Equivalent Circuit Analyses and Methods to Enhance Bandwidth of Klystron Reentrant Cavities
Klystron is used as an amplifier at microwave frequency range. Klystrons use cylindrical or rectangular reentrant cavities in their interaction structure. Characteristics of reentrant cavity can be defined using parameters ...
Precoding and Channel Estimation Schemes for MIMO VLC Systems
Increase in the usage of smartphones and growing demand for data have resulted in
congestion in the RF spectrum. To ease the overcrowding of RF spectrum, there is a
need for wireless communication systems that can ...
Engineering van der Waals Heterojunctions for Electronic and Optoelectronic Device Applications
Efficient preparation and characterization of layered materials and their van der Waals
heterojunctions lay the foundation for various opportunities in both fundamental studies
and device applications. The vast library ...
Spectral Efficiency Improvement in Spatial Modulation Systems
A novel energy efficient Multiple-Input-Multiple-Output (MIMO) technique is called Spatial Mod-
ulation (SM). It uses only one radio frequency (RF) chain that reduces the hardware complexity
and cost of the system. The ...
Transmit Antenna Selection in Underlay Spectrum Sharing: Role of Power Adaptation, Interference Constraint, and Channel State Information
Spectrum sharing is essential to support high wireless data rates and a large number of wireless connections by the future technologies in the limited spectrum that is available. In underlay spectrum sharing a secondary ...
Insights into Network Coding Using Tools From Linear Algebra and Matroid Theory
Traditionally, the transmission of information through a network was carried out using store-and-forward techniques. This entails managing information bits in a network analogous to commodity flow, without mixing or combining ...
Design of Authentication and Privacy Schemes for a Generic Social Network
In social networks, people (also known as actors) are often connected to each other in order to share the
information. With the advancement in the information technology, social networks have in
influenced actors
of ...
