and barrier sizes become smaller (in the order of 100°A or less), enhancement in the multiplication factors as well as the value of ae/ah can still be achieved. However, if the conduction band offset is not very large, the mechanism for such enhancement is different. For example, in the structure of GaAs/

Al0.3Ga0.7As MQW, where Ec:Ev is 57:43, the electrons are not truly confined in the wells because of their small effective mass and electron behavior is similar to that of bulk semiconductor. On the other hand, the holes are confined and experience more scattering in the wells, and so their ionization rate is reduced. Thus an enhancement of ae/ah is obtained as overall effect.

In addition to the low noise performance and gain of the superlattice avalanche photodiodes, they can also provide tunability of the spectral response. In these devices, multiquantum wells with varying sizes of wells and barriers are incorporated at the absorption and multiplication region. The measured spectral response and avalanche gain in respect to the applied reverse bias of

Abstract—As web-server spoofing is increasing, we investigate a novel technology termed ICmetrics, used to identify fraud for given web servers based on measurable quantities/features. The novel concept ICmetrics is used to detect spoof websites with the advantages of a higher level of security with increased speed and template free encryption. ICmetrics technology is based on extracting features from digital systems’ operation that may be integrated together to generate unique identifiers for each of the systems or create unique profiles that describe the systems’ actual behavior. Ideally, the nature of the features should be identical for all of the systems considered, while the values of these features should allow for unique identification of each of the system servers. This paper looks at the properties of the several behaviors as a potential ICmetrics features, and explores properties which affects the stability of the system’s performance. We conclude three requirements for ICmetrics system.

Abstract— In this work we solve a subproblem of the distance geometry problem in molecular conformation. The latter aims to determine the three-dimensional structure of a molecule from a set of imprecisely distances. We are interested only in the bound smoothing subproblem, which aims to tighten bounds from a set of lower and upper bounds on distance for pair of atoms. We apply a Biased

Random-Key Genetic Algorithm to solve this subproblem, where each entry of chromosomes indicates how to decrease a bound, with the fitness function measuring the violation of the triangle inequalities. Experimental results show the effectiveness of this algorithm to solve randomly generated instances for which real distances between atoms are known in advance.

Abstract— The traditional skinning technique used extensively in game development due to its simplicity is notorious for its undesired artifacts. Some of the methods developed provide full control over animation while being highly labor-intensive. A new example-based method for character animation is described. Based on linear blend skinning (LBS) the method extends the concept of Pose

Space Deformation (PSD) technique. The character model is realized as a set of sections, and control cross-sections are defined. To avoid LBS defects, sample control sections are used, with the vertices positions not belonging to the control sections calculated using Catmull-Rom splines with chord-length parameterization.
