FEM based analysis of highpass birdcage resonators for B1 field mapping
(2016)
3D full wave finite element method (FEM) based electromagnetic (EM) analysis is a technique to map EM fields generated by electrical devices. To better understand and apply this technique to magnetic resonance imaging (MRI) ...
DVS-capable ultra-low-power subthreshold CMOS temperature sensor / by Gregory Toombs.
(2010)
There are many contemporary contexts in which a small, low-power-consumption temperature sensor is very valuable. Power, area, speed and temperature range factors are important constraints in modern VLSI design. As transistor ...
Mitigating the impact of decompression latency in L1 compressed data caches via prefetching
(2017)
Expanding cache size is a common approach for reducing cache miss rates and increasing performance in processors. This approach, however, comes at a cost of increased static and dynamic power consumption by the cache. ...
Low temperature epitaxial growth of III-Nitride semiconductors on silicon carbide templates by remote plasma metal-organic chemical vapor deposition
(2018)
Group III-Nitride (III-N) semiconductors are of high interest due to their thermal and electrical properties. Opposed to other III-V group semiconductors III-N semiconductors are hexagonal wurtzite structures that have a ...
Autonomous navigation using image processing
(2016)
In the recent years, the pursuit intelligent and self-operated machines have increased. The human user is to be completely eliminated or minimized as much as possible. It is also popular now to observe machines that are ...
Space shift keying in the presence of multiple co-channel interferers
(2016)
In this thesis, the performance of Space Shift Keying (SSK) Modulation, a technique for
Multiple Input Multiple Output (MIMO) wireless communication systems is studied. The results
are analyzed and compared assuming ...
Attitude control for a quadrotor UAV using adaptive fuzzy backstepping
(2017)
With improvements on automation, computer, electronics and other technologies, applications
of unmanned aerial vehicles (UAVs) have expanded from pure military field to civilian areas.
As a multirotor aircraft, a quadrotor ...
Adaptive backstepping control of quadrotors with neural-network
(2018)
A quadrotor is a type of unmanned aerial vehicles. It has been widely used in aerial
photography. The quadrotor has the capability of vertical takeoff and landing, which is very
useful in small or narrow areas. The ...
Fuzzy adaptive control of a two-wheeled inverted pendulum
(2018)
Recently, the two-wheeled inverted pendulum has drawn the attention of robotic community
in view of a plethora of applications, such as transport vehicles: Segway, teleconferencing
robots, and electronic network-vehicle. ...
A Comparative study of min-sum based decoding algorithms for low density parity check codes
(2012-11-10)
The demand for large scale broadband networks is gaining immense popularity for convenient access of information. A common concern of transmitting data through a wireless medium is the effects of noise on the signal. ...
