In this paper we investigate the control of a PR manipulator to targets that lie on the boundary of its workspace within finite time. This is achieved by introducing a boundary avoidance parameter, Ε, into potential functions defined by constraint boundaries that are incorporated into a Liapunov function. We report and compare on the speed of convergence in two simulationsthat utilise the unique nature of the sliding mode surfaces in both Cartesian and polar formulations.

The features of the innovative partnership called PRIME (Partnership for Regional Innovation in Manufacturing Education) formed in Southwestern Pennsylvania are discussed. The objective of the partnership is to transform academic institutions into educators of highly qualified manufacturing employees who are skilled in math.matics, science and technological innovations. The concept is implemented in many Universities in Pennsylvania. The program helps to counter the shortage of skilled technicians and engineers needed for the sustainable development of the manufacturing industry.

The methods of innovating the manufacturing education and workforce development are discussed. The partnership for regional innovation in manufacturing education (PRIME) is an industry-driven, five college system delivering innovative manufacturing education and carrer development. The objectives of PRIME includes the development of innovative manufacturing programs, building the regional support for the engineering industry, and developing a feeder system. The success of the coalition depends on the implementation of a strategic plan that would address the needs of the region at various levels.

A new idea is proposed to accomplish selective and complete excitation to any specified state among closely lying multi-levels. The basic idea is to control nonadiabatic transitions among dressed states by sweeping the laser frequency periodically. Both three-and four-level models are treated by the semiclassical theory of nonadiabatic transition and conditions of complete excitation are formulated. Numerical demonstrations are presented in comparison with the π-pulse and adiabatic rapid passage.

This paper treats weight distributions of the coset leaders of binary linear block codes. We first present a method for computing the weight distribution of the coset leaders of a given code using two tables each of which stores the weights of the coset leaders of a related code of the code. Then, the weight distributions of the coset leaders of the (N,K) Reed-Muller codes, binary primitive BCH codes, and their extended codes with N ≥ 128 and 29 ≥ N - K ≥ 42 that are obtained by using the computing method are given.

A class of totally disconnected groups consisting of partial direct products on an index set is examined. For such a group, the scale function is found, and for automorphisms arising from permutations of the index set, the tidy subgroups are characterised. When applied to the case where the index set is a finitely-generated free group and the permutation is translation by an element x of the group, the scale depends on the cyclically reduced form of x and the tidy subgroup on the element which conjugates x to its cyclically reduced form.

As the use of real-time multimedia applications increases, bandwidth available to TCP connections is oppressed by "greedy" UDP traffic and their performance extremely deteriorates. In order that both TCP and UDP sessions fairly co-exist in the Internet, UDP sessions should properly react against congestion as TCP. In this work, we implement a "TCP-friendly" rate control mechanism suitable to video applications and investigate its applicability to a real system through observation of the video quality at the receiver. It is shown through our experimental system that we can achieve high-quality and stable video transfer while fairly sharing the network bandwidth with TCP by applying our rate control at a control Interval of 16 or 32 times as long as RTT.

An engineering initiative at Robert Morris College which seeks to enhance the technical and engineering abilities of the workforce in southwestern Pennsylvania is discussed. It aims to do so through an innovative, industry-driven, hands-on, project-based system of education and training that integrates theory and practice in manufacturing, software and logistics engineering. These activities are centered on the computer integrated engineering enterprise (CIEE) - the learning factory at Robert Morris College. The new facility is to be used for teaching, research, lifelong learning and recruiting activities by creating a new paradigm in engineering education.

In this paper the natural boundary reduction for some elliptic boundary value problems with concave angle domains and its natural boundary element methods are investigated. Natural integral equations and Poisson integral formulae are given. A finite element methods of natural integral equations are discussed in details. The convergence of approximate solutions and their error estimates are obtained. Some numerical experiments are presented to demonstrate the performance of the method and our estimates. As an application, we present the coupling of FEM and natural boundary element.

The creation of the partnership for Regional Innovation in Manufacturing Education (PRIME) to address the fundamental mismatch between the labor market and the economy is discussed. Manufacturers in the region show substantial diversity in materials, processes, and technology thereby challenging the educational system that needs to be in place to prepare the regional workforce. The manufacturing base of Southwestern Pennsylvania is the key to healthy economy. Manufacturing is the second largest private sector employer with 166,000 jobs, and first in annual wages with a total payroll of over $6 billion.
