Numerical Investigation Of Heat Transfer In A Cold Plate With Two Different Inlet Location
TABATABAEI MALAZI, Mahdi; SENSOY, Suha; HEPERKAN, Hasan Alpay
We need a uniform temperature distribution for obtaining higher performances from electronic devices. For cooling,
mini-channel cold plates with coolant flow use electronic devices such as Li-ion battery cells and electronic chips. In
this study, two different inlet locations were studied for the thermal management of a plate with constant heat
generation. A commercial computational fluid dynamic software (Ansys-Fluent) was used for the simulation of Minichannel
cold plates with coolant flow and thus pressure drop, temperature and velocity distribution were investigated
numerically. The effect of inlet location on heat transfer and temperature distribution was studied for laminar flow at
two different Reynolds number (Re=500 and Re=1000). Water was used for the coolant flow of the cooling system.
The numerical results show that changing inlet location causes temperature distribution to change at the same number
of coolant channels in a cold plate.

Requirements Of Knowledge Management Implementation In Istanbul Aydin University
ABUGHAZI, Fady M. F.; ŞENER, Uğur
Knowledge is power. After knowledge has started to play an important role in organizations, this paper comes to prove
the importance of knowledge management in the education sector. The study aims to explore the requirements of
knowledge management implementation in Istanbul Aydin University in Turkey. The descriptive analytical approach
is used, and the population of the study was the staff working in Istanbul Aydin University. The questionnaire was
used as a tool for data collection. The collection of data was done by sending an online questionnaire to staff emails
and distributing the questionnaires to the university’s staff by hand. 281 questionnaires were collected and analyzed
statistically by SPSS program. The main conclusions of the study are that knowledge management assists Istanbul
Aydin University to achieve their goals and that there is a positive relationship between the implementation of
knowledge management and the requirements of knowledge management (organizational structure, leadership,
information technology) in Istanbul Aydin University.

A New Triple Band Antenna Design for GPS/ WLAN/ WIMAX Applications
IBRAHIMLI, Ilkin; HIVEHCHI, Hemrah; KARAMZADEH, Saeid
In this work, a novel CPW antenna for wireless communication is proposed. Three practical frequency
bands are achieved by three rectangular slots on the patch and a pair of L-shaped slots and rectangular slots on the
ground. The proposed antenna size is 30×25×0.8 mm3. Simulated results show that the presented antenna can cover
three separated impedance bandwidths of 600 MHz (1.2–1.8 GHz), 400 MHz (2.2–2.6 GHz), and 2000 MHz (4.5–6.5
GHz), which are well applied for WLAN, WIVAX and GPS applications.
