This paper introduces a novel method for Cartesian trajectory and performance optimization control of kinematically-redundant trussbased manipulators (TBMs), The Virtual Serial Manipulator Approach. The approach is to model complex in-parallel-actuated TBMs as simpler kinematically-equivalent virtual serial manipulators. Standard control methods for kinematically-redundant serial manipulators c...

The accumulator-based compaction (ABC) technique uses an accumulator to generate a composite fault signature for a circuit under test. The error coverage for this method has been previously analyzed using Markov chains. We describe an alternative technique for calculating the error coverage of ABC using the asymmetric error model. This technique relies on the central limit theorem of statistics...

5 The purpose of this note is to study the assumption of “mutual information inde6 pendence”, which is used by Zhou (2005) for deriving an output-dependent hidden 7 Markov model, the so-called discriminative HMM (D-HMM), in the context of deter8 mining a stochastic optimal sequence of hidden states. The assumption is extended 9 to derive its generative counterpart, the G-HMM. In addition, state...

Many companies are considering implementing Radio Frequency Identification (RFID) technology to enhance supply chain management through better coordination and collaboration. However, until recently, the incompatibility of RFID systems hindered RFID adoption and impeded coordination and collaboration among adopters. Hence, companies demanded RFID standards. In light of joint RFID standard-makin...

W model strategic behavior of two types of suppliers in B2B spot markets: a supplier that has forward contracts and uses the spot market only for inventory liquidation, and a supplier that uses the spot market as its sole selling channel. We find that when the spot market demand is small, the supplier that has forward contracts has a higher incentive to invest in expanding the spot market. When...

An appropriate definition and efficient computation of similarity (or distance) measures between two stochastic models are of theoretical and practical interest. In this work, a similarity measure, that is, a modified “generalized probability product kernel,” of Gaussian hidden Markov models is introduced. Two efficient schemes for computing this similarity measure are presented. The first sche...

China's urbanization will influence the future world economic development. China's s urbanization rate is from 10.6% in1949 to 53.73% in 2013, and the research center of the experts predict that China's urbanization rate will reach 60% in 2020.The characteristic of China's urbanization is the coordinated development of four modernizations, which includes informatization, industrialization, urba...

the aim of this study was to represent effective componentsin demand chain which help organizations attain high performance levelsthrough identification of these components and determining theirdegree of importance. the following questions were major ideas of thisstudy: what are the most effective components in demand chain? andhow are they effective on organizational performance? to this end,m...

In this work we research the role of body dynamics in the complexity of kinematic patterns in a quadruped robot with compliant legs. Two gait patterns, lateral sequence walk and trot, along with leg length control patterns of different complexity were implemented in a modular, feed-forward locomotion controller. The controller was tested on a small, quadruped robot with compliant, segmented leg...
