COGNITIVE RADIO SOLUTION FOR IEEE 802.22
(2010)
Current wireless systems suffer severe radio spectrum underutilization due to a number of problematic issues, including wasteful static spectrum allocations; fixed radio functionalities and architectures; and limited ...
The Atmospheric Imaging Radar for High Resolution Observations of Severe Weather
(2012)
Mobile weather radars often utilize rapid scan strategies when collecting obser- vations of severe weather. Various techniques have been used to improve volume update times, including the use of agile and multi-beam radars. ...
DEVELOPMENT AND CHARACTERIZATION OF A HIGH-ENERGY IN-LINE PHASE CONTRAST TOMOSYNTHESIS PROTOTYPE
(2016-12-16)
Phase sensitive 3D imaging techniques have been an emerging field in x-ray imaging for two decades. Among them, in-line phase contrast tomosynthesis has been investigated with great potential for translation into clinical ...
ON ANALYTICAL MODELING OF MOBILITY SIGNALLING IN ULTRA DENSE HETNETS
(2018-05-15)
Multi-band and multi-tier network densification is being considered as the most promising solution to overcome the capacity crunch problem in emerging cellular networks. To this end, small cells (SCs) are being deployed ...
Distributed Computation and Optimization over Networks
(2011)
This dissertation is devoted to the development of efficient, robust, and scalable distributed algorithms, which enable agents in a large-scale, multi-hop network to cooperatively compute a global quantity, or solve an ...
Modular Optical Wireless Elements
(2016-12-16)
Optical wireless has gained attention in recent years as an e cient and secure way to provide broadband connectivity to mobile platforms, isolated communities, and crowded public events. Companies like NASA, Google, Facebook, ...
Channel detection on two-dimensional magnetic recording
(2013)
Two-dimensional magnetic recording (TDMR) coupled with shingled-magnetic recording (SMR) is one of next generation techniques for increasing the hard disk drive (HDD) capacity up to 10 Tbit/in2 in order to meet the growing ...
DEEP LEARNING APPROACHES IN PROBLEMS IN VARIOUS-DIMENSIONAL DATA
(2017)
This thesis develop efficient deep learning based methods for a series of tasks. I believe these problems to be inherently worth developing because of their connections to problems of practical importance. In particular, ...
Bayesian Approaches to Detect and Mitigate Ground Clutter mixed with Weather Signals
(2013)
Ground clutter is a long standing issue in radar meteorology, considering that it can bring significant bias to the estimations of weather moments, polarimetric parameters, rainfall rate, hydrometeor identification, etc. ...
THEORETICAL STUDIES OF MULTI-MODE NOON STATES FOR APPLICATIONS IN QUANTUM METROLOGY AND PROPOSALS OF EXPERIMENTAL SETUPS FOR THEIR GENERATION
(2018-05)
Quantum entanglement is a fascinating physical resource that is central to the field of quantum information processing with important applications in such areas as quantum computing, quantum communication, quantum metrology, ...
