This paper studies the kinematic modeling and analysis of two cooperative manipulators. Cooperative manipulators are defined as multi-arm systems working together on a common task. The task is defined as the transportation of an object in space. In this paper the cooperative system is the dual arm of the humanoid Nao robot, where the serial structure of each arm has five degrees of freedom. The...

Entropy generation in an unsteady hydromagnetic Couette flow of a viscous incompressible electrically conducting fluid between two infinite horizontal parallel plates in a rotating system have been analyzed. Both the lower and upper plates of the channel are subjected to asymmetric convective heat exchange with the ambient following the Newton's law of cooling. A numerical solution for governin...

In this paper we develop a set of parallel algorithms for image segmentation basing on the authors' former work, the self-organizing map (SOM) based vector quantization (VQ) approach, by extending the method from serial computation to parallel processing, in order to accelerate the computation process. The parallel segmentation scheme is composed of a group of parallel algorithms for implementi...

Dimensional synthesis of a parallel robot may be the initial stage of its design process, which is usually carried out based on a required workspace. Since optimization of the links lengths of the robot for the workspace is usually done, the workspace computation process must be run numerous times. Hence, importance of the efficiency of the algorithm and the CPU time of the workspace computatio...

Smart metering infrastructure allows for two-way communication and power transfer. Based on this promising technology, we propose a demand-side management (DSM) scheme for a residential neighbourhood of prosumers. Its core is a discrete time dynamic game to schedule individually owned home energy storage. The system model includes an advanced battery model, local generation of renewable energy,...

We present a mathematical framework for constructing and analyzing parallel algorithms for lattice kinetic Monte Carlo (KMC) simulations. The resulting algorithms have the capacity to simulate a wide range of spatio-temporal scales in spatially distributed, non-equilibrium physiochemical processes with complex chemistry and transport micro-mechanisms. Rather than focusing on constructing exactl...

This paper reviews the processes involved in Natural Language Processing (NLP). It then demonstrates the various kinds of choices that need be taken during the execution of the word morphology, the syntactic text analysis, or text generation components. It compares the time complexity of traditional serial algorithms and examines the possible expected gain in some corresponding parallel counter...
