Many heuristics for cost-optimal planning are based on linear programming. We cover several interesting heuristics of this type by a common framework that fixes the objective function of the linear program. Within the framework, constraints from different heuristics can be combined in one heuristic estimate which dominates the maximum of the component heuristics. Different heuristics of the fra...

SUMMARY Consider a regression problem in which there are many more explanatory variables than data points, i.e., p >> n. Essentially, without reducing the number of variables inference is impossible. So, we group the p explanatory variables into blocks by clustering, evaluate statistics on the blocks and then regress the response on these statistics under a penalized error criterion to obtain e...

In many computer-implemented signal-processing systems, it is necessary to perform numerical integrations. If the function to be integrated is a band-limited time signal represented by a set of samples, serious distortion can occur if the wrong integration technique is used. In particular, if the integration is used to calculate a Fourier transform, large error sidelobes will be introduced if S...

Phylogenetic methods are becoming part of the standard methodologies used in the analyses of biological sequence data, but several of the classical tools of phylogenetic inference were not designed with high throughput applications in mind. During our surveys, we haven't found software for the fast inference of neighbor joining trees from sequence alignments which could use biologically realist...

periodic vehicle routing problem focuses on establishing a plan of visits to clients over a given time horizon so as to satisfy some service level while optimizing the routes used in each time period. This paper presents a new effective heuristic algorithm based on data mining tools for periodic vehicle routing problem (PVRP). The related results of proposed algorithm are compared with the resu...

Digital learning environments are increasingly becoming popular in recent years. The rising usage of cell phones has invited researchers to design and develop applications games for mobile phones. Specifically, game-based language is being promoted by many parts the world. “Language Learning Serious Game (LLSG)” based on a theoretical model constructed researcher that supports children English ...

Spatial memory, among many other brain processes, shows hemispheric lateralization. Most of the published evidence suggests that the right hippocampus plays a leading role in the manipulation of spatial information. Concurrently in the hippocampus, memory consolidation during sleep periods is one of the key steps in the formation of newly acquired spatial memory traces. One of the most characte...

There have been studies that investigated mandibular movements and positioning during swallowing, but the results were inconsistent, and still the exact position of the condyles during swallowing is unknown. The purpose of this investigation was to study the kinematics of the mandible and the condyles, and to determine the actual movement paths and position of mandible and condyles during the p...
