A hydraulic circuit of a fluid power system can be considered consisting of hydraulic tubes, local hydraulic resistors, fluid volume elasticity's and flow branching elements. Multi-pole mathematical models with lumped parameters having various causalities are composed for the components. Part I of the paper discusses the principles of composing multi-pole mathematical models for hydraulic circuits. In Part 2 computing steady state conditions and transient responses of the hydraulic circuits in the visual programming environment CoCoViLa are considered. the CoCoViLa environment used for modelling and simulation is a visual programming tool, which supports declarative programming in a high-level language and automatic program synthesis.
Given A is an element of Z(mxn) and b is an element of Z(m), we provide a sharp upper bound for the l(infinity)-distance from any vertex of the polyhedron P(A, b) = {x is an element of R->= 0(n) : Ax = b} to a near...

Given A is an element of Z(mxn) and b is an element of Z(m), we provide a sharp upper bound for the l(infinity)-distance from any vertex of the polyhedron P(A, b) = {x is an element of R->= 0(n) : Ax = b} to a nearby feasible integral point under a strong assumption regarding the dimensions of the matrix A. It is hoped that this result provides motivation for conducting further research into providing more such upper bounds under certain additional assumptions.

this paper presents a canonical dual approach for solving nonconvex quadratic programming problems subjected to both linear inequality constraints and box constrains. It is proved that the constrained nonconvex primal problem can be reformulated as a concave maximization dual problem with zero duality gap, which can be solved under certain conditions. Both global and local extremimality conditions are presented by the triality theory. Several applications are illustrated.

In this paper analytical solution of fastest mixing Markov chain problem over a sensor network with K-partite topology is provided. the solution procedure consists of Stratification of sensor network's connectivity graph and semidefinite programming. the studied topologies are evaluated in terms of asymptotic and per step convergence rates. the obtained optimal transition probabilities have been compared withthose obtained from Metropolis-Hasting method by comparing mixing time improvements numerically.

the incrementally modular abstraction hierarchy, which is a general development method based on modern mathematics, is applied to a computer game implemented by using functional reactive programming within pure functionalprogramming. In this work, this was done by using the Netwire programming library to implement functional reactive programming in the language Haskell, which is based on category theory. We developed the incrementally modular abstraction hierarchy (IMAH) to introduce a modern mathematical method for developing computer games in Netwire and demonstrated that IMAH is capable of facilitating the design and implementation of this challenging but difficult application area.

this paper aims to model system of ordinary differential equations by using a new hybrid gene expression programming algorithm. Gene expression programming is a recently developed evolutionary computation method for model learning and knowledge discovery. the hybrid algorithm combined immune clonal selection algorithm and memetic algorithm with gene expression programming to find not only the structure of system of differential equations but also optimize its constant parameters. the idea of immune clone principle is incorporated into the evolution process to enhance the diversity of population and the memetic algorithm is introduced to improve the ability of local search. Experiments on benchmark problems have shown that the hybrid approach is able to provide highly competitive results compared withthat of conventional genetic programming applied to this problem.

the Perceptron Problem (PP) appeared for the first time in the Learning Machines and is very useful for zero-knowledge identification schemes in cryptology. the problem is NP-complete and no deterministic algorithm is known to date. In this paper we develop a deterministic method based on DC (Difference of Convex functions) programming and DCA (DC optimization Algorithms), an innovative approach in nonconvex programming framework. We first formulate the PP as a concave minimization programming problem. then, we show how to apply DC programming and DCA for the resulting problem. Numerical results demonstrate that the proposed algorithm is promising: its is very fast and can efficiently solve the Perceptron Problem with large sizes.

the C programming Language is one of the most popular teaching programming languages. It is generally considered that the computer programming time that a student spent on his homework directly affects his grade of the C programming Language. there is little research regarding the correlation of students'. computer programming time and their test grades. the computer programming time, grades of final test and the Zhejiang Computer Grade Test Band II (ZCGTBII) of students from a teaching class are collected. the students are divided into two groups based on their programming time. the T-Test is employed to analyze grades of final test and the ZCGTBII of the two groups. Analysis results show that the mean and the passing rates of final test and the ZCGTBII of Group I are greater than those of Group II. therefore, we conclude that the amount of time students spend practicing programming on computers plays a very important role towards mastering the C programming Language.
