Development of various corner-lit backlighting concepts in an advanced smart LED TV
(2015-01)CCFL (Cold Cathode Florescent Lamp) based LCD (Liquid Crystal Display) TVs are replaced by Smart LED TVs with the help of recent improvements of the LED (Light Emitting Diode), electronics and information technologies. ... -
Performance evaluation of unfolded sparse matrix-vector multiplication
(2015-01)Sparse matrix-vector multiplication (spMV) is a kernel operation in scientific com- putation. There exist problems where a matrix is repeatedly multiplied by many different vectors. For such problems, specializing the spMV ... -
Nano-scale chemically modified thin film characterization for chemical mechanical planarization applications
(2015-01)The aim of the microelectronics industry has historically been achieving increasing functionality through decreasing the device sizes while simultaneously reducing the unit manufacturing costs. This objective has been ... -
Limitations of passive thermal management for a-line solid state lighting technologies
(2015-01)Energy has been one of the most important problems for the last few decades. Efficient use of energy is as important as efficiency in energy production and transportation. Solid state lighting (SSL) technology may reduce ... -
Performance analysis of multi-relay free space optical communication systems
(2015-01)Free space optical (FSO) communication has attracted a great attention in recent years because of their high bandwidth capacity in unregulated spectrum which makes them a cost-effective and easy-to-install alternative to ... -
Structural and flow relationship of microfluidics pulsating high and low frequency jets
(2015-06)Synthetic jets are being investigated last several years. Researchers have been interested in its unique applications for a wide range of flow control to thermal management of electronics applications. Synthetic jets are ... -
Reproducing field failures based on semi-formal failure scenario descriptions
(2015-06)Due to the increasing size and complexity of software systems, it becomes hard to test these systems exhaustively. As a result, some faults can be left undetected. Undetected faults can lead to failures in deployed systems. ... -
Localization of biopsy needles in 2D ultrasound images using gabor filter
(2015-06)Needle Biopsies are common medical procedures to remove tissue samples from the body to be examined for diseases. During these procedures, the needle and its tip are tracked using medical imaging devices to avoid damage ... -
A real life operating room scheduling problem
(2015-08)A real life operating room scheduling problem is studied using a data set from a leading hospital, Hospital X, in Turkey. After analyzing the real data, we solve daily operating room scheduling problems by mixed integer ... -
