Computer-based Protocol for Human Simulation Report

The aim of the present case study is to present and evaluate a computer-based standardized procedure to order, perform and document virtual ergonomic analyses. Results showed that the use of the new working methodology increased the number of factors considered during analysis. Participants indicated that the proposed methodology, including task analysis and use of manikin families, would increase

Impulse Radio Pulse Shaping for Ultra-Wide Bandwidth UWB Systems

In this paper, we investigate the design of pulse shaping UK filters for impulse radio ultrawideband (UWB) communications systems. The goal of the shaping is to meet an arbitrary spectrum mask, e.g., the mask mandated by the FCC for UWB emissions. Compared with classical FIR filter designs, the current problem introduces three new challenges: (1) it is minimax with quadratic constraints, (2) a sin

An embedded low power FIR filter

A new sampler with embedded FIR filter was designed with the charge sampling technique. The filter functions by summing the weighted current on a passive capacitor and the weighting factors are decided by the FIR coefficients. The performance of the filter can well compete with conventional analog filter but with smaller area and less power consumption. A testing chip was designed with 2 V supply,

Ekonomisk knapphet, skuldsättning och hälsa

Tillgången på kredit kan öka människors hälsa och välfärd, men mot bakgrund av att skulder så småningom måste betalas tillbaka är det samtidigt tänkbart att överskuldsättning kan ge upphov till försämrad hälsa. I denna rapport använder vi svenska enkät- och registerdata på individnivå för att närmare studera denna fråga. Särskilt undersöker vi sambandet mellan betalningssvårigheter och olika subje

Sensitivity of system reliability to usage profile changes

Usage profiles and component reliability are two important factors in software system reliability estimation. To assess the sensitivity of a system’s reliability to the usage profile and to the reliability of its components, a Markov based system model is used. With the help of this model, the maximum sensitivity to one change or the statistical sensitivity to many independent changes can be estim

Safety culture in air traffic management: Air traffic control

In a joint research project – Human Factors in Air Navigation Services, HUFA – between the Swedish Civil Aviation Administration and Lund University the focus is on human and organizational factors and safety in air traffic control. The Swedish Air Navigation Services (ANS) are undergoing major organizational changes in order to adapt to changing demands on efficiency and technical development in
