In the open-pit mining industry, trucks and shovels are the mining technology of choice;however, it is widely recognized that the operation of these trucks and shovels contributes significantly to the overall operation cost. Fortunately, there exist many opportunities to reduce the cost of the truck and shovel operation. Chador-malu iron ore mine has been exploited since 1997. this deposit is located in the North-East of Yazd province and reserve of this deposit is about 400 million tons. At present, there is a number of loading and haulage equipment which can work for a considerable amount of time in future. In this paper the production rate of trucks in mine routes were obtained by investigating the data and tables of traffic rate in transportation system of mine. then objective function and the constraints of the transportation system were defined. In the next stage, the most suitable rate of trucks, input and output for the possible routes were estimated by the aim of LINDO software.

In a strategic framework, combinators provide a fundamental mechanism for exercising control over rewriting. this type of control is based on the observation of the success or failure of strategy application. this paper describes a framework where information relating to the outcome of strategy application is stored in two internally maintained stacks. these stacks represent an implicit state which is used to control the rewriting process.

A special nonlinear bilevel programming problem (BLPP), whose follower-level problem is a convex programming with a linear objective function in y, is transformed into an equivalent single-level programming by using Karush-Kuhn-Tucker (K-K-T) conditions. To solve the equivalent problem effectively, a new genetic algorithm is proposed. First, a linear programming (LP) is constructed to decrease the dimensions of the transformed problem. then based on a constraint-handling scheme, a second-phase evolving process is designed for some offspring of crossover and mutation, in which the linear property of follower's function is used to generate high quality potential offspring.

SHAM (Single Instruction Multiple Data) is a processor-architecture classification from Flynn's taxonomy. the concept is that a single instruction set operates on multiple units of data simultaneously. Computers use this processor architecture are known as array processors or vector processors. Most computers in use today are SISD (single instruction single data) though allowing a single instruction to operate on multiple data can also be applied to a virtual machine that is capable of parallel execution through the use of multi-threading/multi-core processors, or distributed parallel execution on a multi-computer grid. this paper proposes a language structure that applies the SIMD concept to the Java virtual machine. the motive is to reduce the complexity of the code and ease implementation of parallelization by running a single set of instructions concurrently on an entire collection of objects.

this paper presents Anahy, a programming environment for cluster computing. Anahy is presented in terms of its programming interface (API) and its scheduling mechanism. the main features of this environment are the specification of a POSIX thread-based API and the use of dynamic scheduling techniques based on Directed Acyclic Task Graphs (DAG). the main advantage obtained withthese features is the dissociation between the description of the concurrency of an application and its parallel execution. the paper examines how Anahy builds a DAG describing the dependencies among tasks at execution time from a multithreaded program and how this DAG is handled by the runtime to apply dynamic scheduling techniques. the paper concludes discussing three case studies of applications developed in the context of Anahy environment.

this paper proposes a new method to synthesize practical passive filter using Clonal Selection principle-based Gene Expression programming and binary tree representation. the circuit encoding of this method is simple and efficient. Using this method, boththe circuit topology and component parameters can be evolved simultaneously. Discrete component value is used in the algorithm for practical implementation. Two kinds of filters are experimented to verify the excellence of our method, experimental results show that this approach can generate passive RLC filters quickly and effectively.

Although many methodologies have been proposed for solving the cell-formation problem, few of them explicitly consider the existence of multiple objectives in the design process. In this article, the development of multi-objective genetic programming single-linkage cluster analysis (GP-SLCA), an evolutionary methodology for the solution of the multi-objective cell-formation problem, is described. the proposed methodology combines an existing algorithm for the solution of single-objective cell-formation problems with NSGA-II, an elitist evolutionary multi-objective optimization technique. Multi-objective GP-SLCA is able to generate automatically a set of non-dominated solutions for a given multi-objective cell-formation problem. the benefits of the proposed approach are illustrated using an example test problem taken from the literature and an industrial case study.

In this paper we present JaceV, a multi-threaded Java based library designed to build asynchronous parallel iterative applications (with direct communications between computation nodes) and execute them in a volatile environment. We describe the components of the system and evaluate the performance of JaceV withthe implementation and execution of an iterative application with volatile nodes.
