Sensing and analysis of angular vibrations of tremor
(Northern Illinois University, 2014)
Tremor is defined as the unintentional involuntary muscle movements involving rhythmic oscillations of any part of body like legs, hands, arms and limbs. This thesis deals with the most common tremor that occurs in hands. ...
Performance evaluation of subcarrier mapping techniques for multiuser in presence of Doppler in LTE uplink
(Northern Illinois University, 2014)
Orthogonal Frequency Division Multiplexing (OFDM) is an advanced 3G/4G scheme which achieves high data rate and combats multipath fading. However, OFDM systems suffer from nonlinear peak to average power ratio (PAPR) and ...
Performance evaluation of fixed and variable zero padding length in ultra-wideband receiver design using MB-OFDM based on ECMA-368 standard
(Northern Illinois University, 2014)
Traditional OFDM systems use Cyclic Prefix (CP) in front of an OFDM symbol to maintain orthogonality. Ultra Wide Band (UWB) systems use Multiband OFDM approach in implementing applications of Wireless Personal Area Network ...
Maximum power point tracking of a solar panel using a DC bus
(Northern Illinois University, 2014)
A system is designed to extract the maximum power from a solar panel using SIMULINK software. The main objective of this thesis is to track the maximum power point from a solar panel by using a DC bus and to notice the ...
Controlling AC motor using Arduino microcontroller
(Northern Illinois University, 2014)
Space vector Modulation (SVM) is a technique used for generating alternating current waveforms to control pulse width modulation signals (PWM). It provides better results of PWM signals compared to other techniques. CORDIC ...
Back biasing technique in preventing clogging of pores on the porous silicon templates for the deposition of zinc oxide
(Northern Illinois University, 2014)
The main objective of this thesis is to study the thin layer that seemed to have been formed during the electrochemical etching process and devise a method to remove this layer and subsequently deposit Zinc Oxide using ...
Magnetic circuit utilizing soft switching for LED driving
(Northern Illinois University, 2014)
LEDs are the most efficient way to turn an electric current into illumination. Connecting LEDs in either series or parallel is considered to be an option for better lighting and various other applications. Generally, when ...
Enhanced multi-channel active noise control system and real-time implementation for infant incubator
(Northern Illinois University, 2014)
The active noise control (ANC) system is implemented in the infant incubator and confirmed to improve environment effectively for infants. However, the traditional ANC systems cannot be applied directly to incubators without ...
One-directional normally-on vertical silicon carbide (3C-SiC) MESFET on silicon (Si) substrate
(Northern Illinois University, 2014)
The main objective of this thesis is to design a one-directional normally-on vertical 3C-SiC MESFET on silicon substrate. The 3C-SiC material has higher carrier mobility, high saturation velocity and high critical breakdown ...
Papr reduction in OFDM using hybrid method
(Northern Illinois University, 2014)
Orthogonal frequency division multiplexing (OFDM) is a modulation technique which revolutionized the field of communications and paved the way for the modern-day 4G LTE communications. OFDM technique is used in both wired ...
