In this letter, we address geometry coding of 3-D mesh models. Using a joint prediction, the encoder predicts vertex positions in the layer traversal order. After we apply the joint prediction algorithm to eliminate redundancy among vertex positions using both position and angle values of neighboring triangles, we encode those prediction errors using a uniform quantizer and an entropy coder. Th...

This paper analyzes the effects of a potential spillover on technology transfer of a multinational enterprise and on the host country policy. In particular, we examine how both parties’ incentives can be controlled through the ownership structure in an international joint venture. In contrast to existing arguments we show that spillovers must not always have negative effects on technology trans...

Joints are failure points for deployable systems and moving devices. Their reliability and efficiency are of great concern for space applications. In this paper we present a new biologically inspired joint for space applications that has a minimal number of parts and requires no bearings. Its principle is based on a compliant structure that changes shape with Shape Memory Alloy actuators. An ex...

As part of the adoption of the 2005 Building Energy Efficiency Standards, the California Energy Commission adopted Joint Appendix IV, which contains standard U-factor, C-factor and Thermal Mass data for roof, wall and floor construction assemblies (see page IV-1 of the Joint Appendices at: http://www.energy.ca.aov/title24/2005standards/2004-10-06 400-03-001JAF.PDF). The data in Joint Appendix I...

We investigate the impact of self-interference on the performance of joint partial RAKE (PRAKE) receiver and adaptive modulation over both independent and identically distributed and independent but non-identically distributed Rayleigh fading channels in the presence of self-interference in terms of the average spectral efficiency as performance measures. Some selected results show the performa...

This paper surveys the literature on the joint production of good and bad outputs. Recently, material balance has arisen as an issue in this literature as a restriction on the technology, which we also address. We use our preferred specification of joint production technology and estimate the efficiency of U.S. electric utilities in a network setting. This network allows to specify two subtechn...

A class of simple Jacobi-type algorithms for non-orthogonal matrix joint diagonalization based on the LU or QR factorization is introduced. By appropriate parametrization of the underlying manifolds, i.e. using triangular and orthogonal Jacobi matrices we replace a high dimensional minimization problem by a sequence of simple one dimensional minimization problems. In addition, a new scale-invar...

This paper evaluates power transfer or shifting across upper-limb segments, resulting from fatigue-inducing wheelchair propulsion. Nineteen manual wheelchair users (WCUs) and ten nonwheelchair users (NUs) participated in this study. Subjects propelled an instrumented wheelchair ergometer at a workload corresponding to 75% of the peak oxygen uptake attained during a maximal-graded exercise toler...

Current articulating electric and body-powered hands have a lower pinch force (15-34 N) than electric hands with stiff fingers (55-100 N). The cosmetic glove, which covers a hand prosthesis, negatively affects the mechanical efficiency of a prosthesis. The goal of this study is to mechanically compare polyvinylchloride (PVC) and silicone cosmetic gloves and quantify the stiffness of the finger ...
