Today, link-state routing protocols that compute multiple shortest paths predominate in data center and campus networks, where routing is performed either in layer three or in layer two using link-state routing protocols. But current proposals based on link-state routing do not adapt well to real time tra c variations and become very complex when attempting to balance the tra c load. We propose...

A positive integer N is called an abundant number if σ(N) > 2N, where σ (N) denotes the suns of the divisors of N including 1 and N. Abundant numbers have been recently investigated by Behrend, Chowla, Davenport , myself, and others ; it has been proved, for example, that they have a density greater than 0 . I prove now the following THEOREM. We can find two constants c l , c 2 such that , for ...

A temporal graph is a in which the edge set can change from one time step to next. The exploration problem TEXP of computing foremost schedule for graph, i.e., walk that starts at given start node, visits all nodes and has smallest arrival time. In first part paper, we consider only undirected graphs are connected each step. For such with $n$ nodes, show it \NP-hard approximate ratio $O(n^{1-\v...

in this research, recognition of karstic water-bearing zones using the management of exploration data in kal-qorno valley, situated in the tepal area of shahrood, has been considered. for this purpose, the sequential exploration method was conducted using geological evidences and applying remote sensing and geoelectrical resistivity methods in two major phases including the regional and local s...

Log-domain current-mode multiphase sinusoidal oscillators based on all-pass filters are presented in this paper. The first-order differential equation is used for obtaining inverting and non-inverting all-pass filters. The proposed oscillators are realized by all-pass filters whose natural frequency and stage gain can be electronically tuned by adjusting the bias currents. Each all pass filter ...

Data is often recorded, captured, and stored automatically via sensors and monitoring systems. Many of the simple transactions now part of our everyday lives, such as paying for food and clothes by credit card or using the telephone, are typically recorded for future reference by computers. Many parameters of each transaction are routinely captured, resulting in highly dimensional data. The dat...

The P10 well is located offshore, in the Northern part of Rio Del Rey basin southwest Cameroon. Although most prolific coastal Cameroon given production results from several fields southern part, yet it remains very little explored its northern part. This work evaluation petroleum potential Basin using a combination "Quick Look" interpretation logs recorded and "compl...

Well log data analysis plays an important role in petroleum exploration. It is used to identify the potential for oil production at a given source and so forms the basis for the estimation of financial returns and economic benefits. In recent years, many computational intelligence techniques such as backpropagation neural networks (BPNN) and fuzzy systems have been applied to perform the task. ...
