hyperspectral image super resolution extending an effective fusion based method without knowing the spatial Transformation Matrix
International Conference on Multimedia and Expo, 2017Co-Authors: Lei Zhang, Chunna Tian, Chen Ding, Yanning Zhang, Wei WeiAbstract:Hyperspectral image (HSI) super-resolution, a technique to obtain higher (often spatial) resolution image from the original image, has been extensively studied and applied to lots of fields such as computer vision, remote sensing, etc. Though fusion based method has achieved state-of-the-art result, it always assume the spatial Transformation Matrix is given in advance, whereas such a Matrix is actually unknown in reality. An unsuitable given Matrix will deteriorate the superresolution result greatly. To address this issue, we propose a novel fusion based HSI super-resolution method without knowing the spatial Transformation Matrix. Specifically, we incorporate super-resolution and spatial Transformation Matrix estimation into a unified framework. We alternately estimate the Matrix and the higher spatial resolution HSI. We find that without given the spatial Transformation Matrix, the proposed method can obtain more accurate reconstruction result compared with other competing methods. Experimental results demonstrate the effectiveness of the proposed method.

agile supply chain Transformation Matrix an integrated tool for creating an agile enterprise
Supply Chain Management, 2007Co-Authors: Manisra Baramichai, Emory W Zimmers, Charalambos A MarangosAbstract:Purpose – The purpose of this paper is to propose a tool, the Agile Supply Chain Transformation Matrix (ASCTM), and the implementation methodology for a systematic approach to achieve agility in the supplier‐buyer supply chain.Design/methodology/approach – The conceptual framework for agile capability creation is developed based on literatures in the supply chain management and manufacturing agility field and the ASCTM tool is constructed using the quality function deployment (QFD) and the analytic hierarchy process (AHP) technique. The implementation methodology including the tools to support the implementation of the ASCTM tool are developed based on the QFD/AHP approach and the agility concepts established through the Agility Program at Lehigh University. A practical case study is used to illustrate the applicability of the ASCTM tool.Findings – This tool can help companies create and improve their agility by relating the business changes with the appropriate approaches for supplier‐buyer supply chain ...

agile supply chain Transformation Matrix a qfd based tool for improving enterprise agility
International Journal of Value Chain Management, 2007Co-Authors: Manisra Baramichai, Emory W Zimmers, Charalambos A MarangosAbstract:Under today's volatile business environment, companies are reaching the point where they need to be more agile intelligent, fast, flexible, and responsive to changes. Leveraging supplier-buyer relationship to create an agile supply chain is one of the strategies that can help companies make a successful transition to an agile enterprise. Here we introduce a model that can be used to successfully transform a business: the Agile Supply Chain Transformation Matrix (ASCTM), a tool based on the Quality Function Deployment (QFD), and the Analytic Hierarchy Process (AHP). More specifically, we have created a tool that can relate the business changes with the appropriate approaches for supply chain configuration and supplier-buyer relationship establishment and determine the business processes and the infrastructures needed to support agility. This tool is built upon the concepts developed through the Agility Programme at Lehigh University in partnership with company project sponsors and the Commonwealth of Pennsylvania Department of Community and Economic Development.

modular relative jacobian for dual arms and the wrench Transformation Matrix
Robotics Automation and Mechatronics, 2015Co-Authors: Rodrigo S. Jamisola, Petar Kormushev, Darwin G Caldwell, F IbikunleAbstract:A modular relative Jacobian is recently derived and is expressed in terms of the individual Jacobians of stand-alone manipulators. It includes a wrench Transformation Matrix, which was not shown in earlier expressions. This paper is an experimental extension of that recent work, which showed that at higher angular end-effector velocities the contribution of the wrench Transformation Matrix cannot be ignored. In this work, we investigate the dual-arm force control performance, without necessarily driving the end-effectors at higher angular velocities. We compare experimental results for two cases: modular relative Jacobian with and without the wrench Transformation Matrix. The experimental setup is a dual-arm system consisting of two KUKA LWR robots. Two experimental tasks are used: relative end-effector motion and coordinated independent tasks, where a force controller is implemented in both tasks. Furthermore, we show in an experimental design that the use of a relative Jacobian affords less accurate task specifications for a highly complicated task requirement for both end-effectors of the dual-arm. Experimental results on the force control performance are compared and analyzed.

Quasi-modes three-phase transmission line model : Transformation Matrix equations
International Journal of Electrical Power & Energy Systems, 2001Co-Authors: M C Tavares, José Pissolato, C.m. PortelaAbstract:Abstract This paper describes the quasi-modes three-phase transmission line model, a new model to represent three-phase transmission lines in transient studies, with proper representation of the frequency dependence of longitudinal parameters. A unique Transformation Matrix—the Clarke Matrix—is used for the entire frequency range. As this Matrix is a real one. it can be modeled through ideal transformers. The circuit equations, which lead to the Matrix modeling, are presented. This line model can be implemented in any digital program with R , L , C and transformer components.
