A method for efficient measurement-based COTS assessment and selection - Method description and evaluation results

The use of Commercial-off-the-Shelf (COTS) software has become more and more important in state-of-the-art and state-of-the-practice software and system development. The use of COTS software promises faster time-to-market, reduced development cost, increased productivity, and the possibility for companies to focus on their own core competencies. At the same time COTS software raises risks such as

Temperature limit values for gripping cold surfaces

Objectives. At the request of the European Commission and in the framework of the European Machinery Directive, research was conducted jointly in five different laboratories to develop specifications for surface temperature limit values for the gripping and handling of cold items. Methods. Four hundred and fourteen experiments were run where male and female subjects were invited to grip for up to

On Multilink Shadowing Effects in Measured V2V Channels on Highway

Shadowing from vehicles can degrade the performance of vehicle-to-vehicle (V2V) communication systems significantly. It is thus important to characterize and model the influence of common shadowing objects like cars properly. For multilink systems it is essential to model the joint effects on the different links. However, the multilink shadowing effects in V2V channels are not yet well understood.

Onset of mould growth – the effect of climate variability and different geographic locations

This paper presents a study on how climate conditions at numerous locations in Sweden affect the risk of onset of mould on wood sheltered outdoors. The results indicate that the risk is clearly higher in the south compared to the north of Sweden. These differences are mainly explained by colder and dryer winter periods in the north which is unfavorable for development of mould. The results also sh

Konkurrensrätt och parallellimport – Exportförbudsklausuler

En aspekt som kommit bort i diskussionen efter EG-domstolens dom i Silhouette-fallet var påståendet att Silhouette hade infört någon form av reexportförbud i sitt avtal med den bulgariske köparen. Silhouettes agent i Bulgarien hävdade att så var fallet, men de närmare omständigheterna kring försäljningen blev aldrig klarlagda. Frågan lyftes inte heller fram i den österrikiska domstolens begäran om

A sign-bit auto-correlation architecture for fractional frequency offset estimation in OFDM

This paper presents an architecture of an auto-correlator for Orthogonal Frequency Division Multiplexing systems. The received signal is quantized to only the sign-bit, which dramatically simplifies the frequency offset estimation. Hardware cost is reduced under the assumption that synchronization during acquisition does not have to be very accurate, but sufficient for coarse estimation. The archi
