Abstract -In today’s world of Internet every digitized object can be made exchangeable and transferable over the communication channel for various purposes. There are numerous security threats over the internet for digitized objects and hence they have to be made secure. Therefore, methods like steganography are gaining importance day by day. Steganography is the art which tends to obscure a pa...

By using a gas balance technique, the effective oxidative phosphorylation ratio in glucose-limited continuous cultures of Candida parapsilosis was calculated to be 2.4 +/- 0.2. When this value was used, the molar growth yield with respect to adenosine 5'-triphosphate was found to be 10 g of cells produced per mol of ATP.

The Capacity Assignment problem focuses on finding the best possible set of capacities for the links that satisfy the traffic requirements in a prioritized network while minimizing the cost. Apart from the traditional methods for solving this NP-Hard problem, one new method that uses Learning Automata (LA) strategies has been recently reported. This method uses discretized learning automata [1]...

Continuous Conceptual Set Covering (CCSC) is an algorithm that uses engineering knowledge to learn operator effects from training examples. The program produces an operator hypothesis that, even in noisy and nondeterministic domains, can make good quantitative predictions. An empirical evaluation in the traytilting domain shows that CCSC learns faster than an alternative case-based approach. Th...

Head pose is a rich visual cue that finds great interest in the field of human robot interaction (HRI) and for video surveillance applications. Previous attempts at solving this problem have often proposed solutions formulated in a classification setting. Furthermore, strong assumptions on illumination and scale in an occlusion-free environment have usually been made. We propose a regression so...

Introduction: Diffusion weighted imaging (DWI) has become indispensable in clinical routine, especially due to its sensitivity to early stages of brain ischemia. Patient motion during measurements is a major source of artifacts. A distinction must be made between motions during the acquisition of a single diffusion encoded image (intrascan) and movements in between these images (interscan) as w...

neurokinin 1 receptors (nk1r) are overexpressed on several types of important human cancer cells. substance p (sp) is the most specific endogenous ligand known for nk1rs. accordingly, a new sp analogue was synthesized and evaluated for detection of nk1r positive tumors. [6-hydrazinopyridine-3-carboxylic acid (hynic)-tyr8-met(o)11-sp] was synthesized and radiolabeled with 99mtc using ethylenedia...
