Extracting generic bases of association rules seems to be a promising issue in order to present informative and compact user addedvalue knowledge. However, extracting generic bases requires partially ordering costly computed itemset closures. To avoid the nightmarish itemset closure computation cost, specially for sparse contexts, we introduce an algorithm, called Prince, allowing an astute ext...

We study the behaviour at the terminal time T of the minimal solution of a backward stochastic differential equation when the terminal data can take the value +∞ with positive probability. In a previous paper [15], we have proved existence of this minimal solution (in a weak sense) in a quite general setting. But two questions arise in this context and were still open: is the solution right con...

We present a framework for the automatic con guration of large systems from a library of reusable software components. Core of the framework is a modal logic that uniformly and elegantly captures type descriptions, module speci cations and relative time. Whereas the rst two `dimensions' are treated similarly by means of a simple logic over a taxonomy of types and modules respectively, time is e...

Temperature control is widely sought after in regards to optical systems as their optical parameters often show dependence on temperature. Examples include diode lasers, multiplexing systems, optical amplifiers, and filters all of whom have a high sensitivity to temperature. This thesis presents a temperature controlled environment chamber actuated by a thermoelectric cooler. The design of whic...

We present an approach to the problem of mobile robot motion planning in arbitrary cost fields subject to differential constraints. Given a model of vehicle maneuverability, a trajectory generator solves the two point boundary value problem of connecting two points in state space with a feasible motion. We use this capacity to compute a control set which connects any state to its reachable neig...

in this paper the effect of block shape vortex generators (vgs) on an air-water fin-tube heat exchanger has been studied experimentally using exergy analysis method. also the effect of these vgs on increasing heat transfer rate has been simulated numerically and the results show a good agreement with the experiments. in this research we used a wind tunnel to produce wind flow over heat exchange...

We describe how dependencies between random numbers generated with some popular pseudorandom number generators can be detected using general purpose machine learning techniques. This is a novel approach, since usually, pseudorandom number generators are evaluated using tests specifically designed for this purpose. Such specific tests are more sensitive. Hence, detecting the dependence using mac...

As a motivating application for the study of lattice in cryptography we consider the construction of pseudorandom generators. We recall that a pseudorandom generator is a program G(x) (computable in deterministic polynomial time) that maps bitstrings x ∈ {0, 1} to longer strings G(x) ∈ {0, 1} such that, if x is chosen uniformly at random and kept secret, then the output G(x) will “look” random ...

The paper presents a novel self adjusting wind energy utilization scheme using a modified single phase operation of the three phase induction generator. The proposed scheme is supplemented by a voltage stabilization switched filter compensation schemes which is controlled by a dynamic Multi Objective Genetic Algorithm MOGA error driven self adjusting PID controller. The Green Plug Filter Compen...
