Power of inhibition activity screening and 3D molecular modeling approaches in HDAC 8 inhibitor design
(Scientific Technical Research Council Turkey-Tubitak, 2011)In-vitro inhibition activity screening and in-silico 3D molecular modeling approaches are important tools for design and development of specific histone deacetylase (HDAC) inhibitors. The objective of this study was to ... -
Power transfer networks at RF frequencies "New design procedures with implementation roadmap"
(IEEE, 2006)The purpose of this work is to provide the necessary background to design wide-band power transfer two-ports, or so-called broadband matching networks, at radio frequencies for wireless communication systems. The importance ... -
Practical Implementation of the Combinational Cooperative Detection Method
(Springer, 2015)In conventional cooperative detection a fusion center decides on the presence or the absence of a primary user (PU) by gathering all the information from secondary users (SUs) and conveys this decision to all users. This ... -
Prayer bead gestures and television: A case study on cultural inspirations for interaction art education
(MIT Press Journals, 2009)The authors interactive design-art educators recount their experience in using cultural inspirations as part of student exercises. The authors found that although students proposed various design concepts drawing from the ... -
Precoded single-cell multi-user MISO visible light communications
(Institute of Electrical and Electronics Engineers Inc., 2015)This study investigates the effects of transmitter and receiver parameters on the performance of a precoded singlecell (SC) multi-user (MU) multi-input-single-output (MISO) visible light communication (VLC) system. A ... -
