Innovation in periods of crisis and growth. Sectoral patterns of innovation in Swedish manufacturing (1970-2007)

Whether and how innovation activity is dependent upon economic factors has been discussed extensively. Most empirical studies on the subject have either used patent data as a proxy for innovation, or been conducted at an aggregate level. Using a new database on Swedish product innovations (Swinno) this paper examines in what way patterns of innovation activity varied across and within manufacturin

Hur ser pilgrimens värld ut? En sociologisk analys av Hans-Erik Lindströms pilgrimsteologi

This article analyses and discusses the world view and the theology of Hans-Erik Lindström, author of several pilgrimage books and the founder of the Pilgrim’s Centre in Vadstena. Lindström’s pilgrimage theology is based upon seven keywords: slowness, freedom, simplicity, silence, light-heartedness, sharing and spirituality. These are assumed to be the pilgrim’s longings that can not be found in t

Reflections on Process-based Supply Chain Modelling and Analysis

The interest in modelling, analysis and optimisation of supply chain structures has increased in the last decade. Among the reasons are globalisation, a general speed-up of the rate of change in the business environment, the trend towards more outsourcing of activities, and the rapid development in IT. This development has caused more and more people to realise the benefits of supply chain managem

Analysis and design of a low-power single-stage CMOS wireless receiver

Abstract—The thorough analysis and the design of a complete 2.2 GHz quadrature receiver front-end suited for low-power applications is reported in this work. The circuit, built in a 90nm CMOS process, features a stacked single-ended low-noise amplifier and a self-oscillating mixer. The oscillator LC tank is designed to provide gain at low frequency without decreasing the quality factor at the osci

Practical Issues in the Implementation of Self-Tuning Control

Implementation aspects of self-tuning regulators are discussed in the paper. There is a large discrepancy between simulation or academic algorithms and practical algorithms. In the idealized environment of simulations it is easy to get different types of adaptive algorithms to perform well. In practice the situation is quite opposite. The adaptive or self-tuning controller must be able to handle n

Semidefinite Hankel-type Model Reduction Based on Frequency Response Matching

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

Cross-fertilizing change and crisis research: Towards a better understanding of internal crisis communication

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

A simultaneous maximum likelihood estimator based on a generalized matched filter

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
