Myndigheterna borde tacka hackarna, inte åtala dem

Huvudboven i den stora dataintrångsmål som idag avslutas är inte hackaren Gottfrid Svartholm Warg – utan myndigheter som Skatteverket och Kronofogden, som inte tar hand om persondata på ett säkert sätt. När personuppgifter kommer på vift borde den som är ansvarig åläggas att informera berörda parter.

Effects of Neglecting Buffers in Feed-Forward Design for Web Servers

This paper addresses a problem related to control of web servers. Due to implementation issues, relevant measurements are only taken over the a limit part of the server system, which leaves the controller unaware of what happens in buffers proceeding the actual web-server (for instance in the TCP/IP layers). We model this and reveals that the unmeasured buffering introduces an extra zero in the re

Annie, a Tool for Integrating Ergonomics in the Design of Car Interiors

In this ANNIE project – Applications of Neural Networks to Integrated Ergonomics – BE96-3433, a tool for integrating ergonomics into the design process is developed. This paper presents some features in the current ANNIE as applied to the design of car interiors. A variant of the ERGOMan mannequin with vision is controlled by a hybrid system for neuro-fuzzy simulation. It is trained by using an El

An Industrial Adaptive PID Controller

This paper presents a new industrial adaptive PID controller. The controller has the PID structure, with dual rate sampling, which means that the sampling rate for the PID controller is significantly higher than the sampling rate in the parameter estimator. The controller differs from conventional parametric adaptive controllers because it is based on estimation of transfer function properties. Fo

Performance and efficiency evaluation of FPGA controlled IPMSM under dynamic loading

This paper presents an improved synthetic loading method to measure the performance of an interior permanent magnet synchronous machine (IPMSM). A complete analysis of torque-, flux-, and efficiency-maps are done by means of a vector controlled drive implemented with in a field programmable gate array (FPGA). The measurements are compared to results from Finite Element Analysis (FEA). A key featur

Polyploid evolution in the European orchid genus Nigritella: evidence from DNA fingerprinting

The genus Nigritella (Orchidaceae-Orchidinae) is a complex of species at four different ploidy levels. Fourteen taxa at species or subspecies level have been distinguished. The triploid N. nigra ssp. nigra is endemic to Scandinavia, whereas the remaining taxa are confined to different mountain regions in Central and Southern Europe. The polyploids are of hybrid origin and have arisen from taxa at
