The orientation of physical networks is a prime task in deciphering the signaling-regulatory circuitry of the cell. One manifestation of this computational task is as a maximum graph orientation problem, where given an undirected graph with n vertices and a collection of vertex pairs, the goal is to orient the edges of the graph so that a maximum number of pairs are connected by a directed path...

Current emerging embedded System-on-Chip platforms are increasingly becoming multiprocessor architectures. System designers experience significant difficulties in programming these platforms. The applications are typically specified as sequential programs that do not reveal the available parallelism in an application, thereby hindering the efficient mapping of an application onto a parallel mul...

Improving time series forecastingaccuracy is an important yet often difficult task.Both theoretical and empirical findings haveindicated that integration of several models is an effectiveway to improve predictive performance, especiallywhen the models in combination are quite different. In this paper,a model of the hybrid artificial neural networks andfuzzy model is proposed for time series for...

Introduction: Long-term use of narcotics causes hyperalgesia in some patients with an unknown mechanism known as opioid-induced (OIH). Case Presentation: Testosterone was prescribed to a 43-year-old man suffering from the effects OIH syndrome due long-term methadone. prescription significantly reduced hyperalgesia. Conclusions: may have therapeutic value OIH.

The search space of Bayesian Network struc­ tures is usually defined as Acyclic Directed Graphs (DAGs) and the search is done by lo­ cal transformations of DAGs. But the space of Bayesian Networks is ordered with respect to inclusion and it is natural to consider that a good search policy should take this into ac­ count. The first attempt to do this (Chick­ ering 1996) was using equivalence cla...

This paper proposes an improved Life-365™ model, which is used to life cycle cost analysis. The main content as follows: (1) existing model was based on artificial neural networks, and the predicted results of were in good agreement with experimental data. (2) Adding fibres concrete can improve durability structure, but unable reduce structure. (3) use BFRP reinforcement instead steel improves ...

one of the most important issues related to knowledge discovery is the field of comment mining. opinion mining is a tool through which the opinions of people who comment about a specific issue can be evaluated in order to achieve some interesting results. this is a subset of data mining. opinion mining can be improved using the data mining algorithms. one of the important parts of opinion minin...

Software maintenance phase is started once a software project has been developed and delivered. After that, any modification to it corresponds to maintenance. Software maintenance involves modifications to keep a software project usable in a changed or a changing environment, to correct discovered faults, and modifications, and to improve performance or maintainability. Software maintenance and...
