The various types of synthetic discriminant function (sdf) filter result in a weighted linear superposition of the training set images. Neural network training procedures result in a non-linear superposition of the training set images or, effectively, a feature extraction process, which leads to better interpolation properties than achievable with the sdf filter. However, generally, shift invar...

Grain growth and hardness variation occurring in high-temperature heat affected zone (HAZ) during the welding processes are two thermal dependant aspects of great interest for both academic industrial research activities. This paper presents an innovative finite element (FE) model capable to describe grain decrease that occur gas metal arc (GMAW) commercial AISI 441 steel. The FE software SFTC ...

This paper assumes each user has more than one queue, derives a new packet-dependant proportional fairness power allocation pattern based on the sum of weight capacity and the packet’s priority in users’ queues, and proposes 4 new cross-layer packet-dependant OFDM scheduling schemes based on proportional fairness for heterogeneous classes of traffic. Scenario 1, scenario 2 and scenario 3 lead r...

An evolutionary algorithm that utilizes a-priori problem specific information and allows intuitive representation of the problem design variables is proposed. A technique for conditioning the components of the fitness statement using ranking and a graphical method for monitoring components of the rank based fitness function are presented. By utilizing generationally dependant non-linear rank ba...

There are several broad attributes that can be used to describe video. For example, video can be categorized as real time or pre-recorded, streaming or pre-positioned, and high resolution or low resolution. The network load is dependant on the type of video being sent. Pre-recorded, pre-positioned, low resolution video is little more than a file transfer while real-time streaming video demands ...
