This paper is dedicated to model order reduction of linear time-invariant systems. The main contribution of this paper is the derivation of two scalable stability-preserving model reduction algorithms. Both algorithms constitute a development of a recently proposed model reduction method. The algorithms perform a curve fitting procedure using frequency response samples of a model and semidefinite
The overall purpose of this paper is to contribute to the development of an internal crisis communication perspective. More precisely, we want to discuss and illuminate the need for an emergent, co-worker-oriented perspective on crises. Such a perspective implies a broader view on crises and a need to include change communication as an allied re-search field to crisis communication, and not at lea
The paper discusses parameter estimation and detection in Laplace distributed noise. The received signal is modeled as r(·)=As(·,&thetas;)+n(·), where A is an unknown amplitude, &thetas; is the parameter vector to be estimated and n(·) is independent Laplace distributed noise. The simultaneous maximum likelihood estimator of (A,&thetas;) is derived. The derived estimator is based on a
A stratified sample of 118 university teachers took part in an investigation in which they assessed their organization on 17 dimensions. Two of the dimensions, creativity and productivity, were regarded as consequences of organizational conditions. Each of two factor analyses carried out, one including gender and the other not, yielded five factors, one of them formed by the dimensions of creativi
The aim of this study was to visualize design regulations of furniture by means of interactive multimedia technology based on cognitive theories and practical examples. Furthermore, the usage of the visualized regulations to support education, communication, learnability, relevance and attitudes was evaluated. The visualized regulations were the result of a design process involving experts and pot
Proton exchange membrane fuel cells (PEMFCs) are highly integrated to include fuel processing, fuel cell stack, associated heat exchangers and/or post-combustion units. The integration is in terms of not only species flows, but also energy balances. This paper presents a simulation approach to analyze and improve PEMFCs stack and heat rejection load on the radiator. It is based on an overall fuel
This paper presents BlueJEP, a novel Java embedded processor, developed using the relatively new Bluespec SystemVerilog (BSV) environment. The starting point for Blue-JEP is a micro-programmed, pipelined, Java-optimized processor (jop), written in VHDL. Our BSV solution features a number of design choices, including a longer pipeline and speculative execution, that make the design more flexible, m
Sphere decoders can approach the performance of maximum-likelihood (ML) decoders for MIMO systems with lower complexity. In this paper, VLSI architecture of the modified K-best Schnorr-Euchner (MKSE) sphere decoder is proposed for soft-output MIMO decoding. The MKSE decoder can achieve near-ML performance with higher decoding throughput and lower computational complexity. The proposed VLSI archite
