The welding procedure to seal copper canisters requires variable power input throughout the 45 minute long weld cycle to keep the probe temperature within the process window. By using a cascaded loop that determines the power input requirement, the controller will not be dependent on repeatability in the necessary power input between weld cycles, and the lag time in the probe temperature measureme

Trots att jordbrukslandskapet enbart utgör en liten andel av Sveriges totala yta så är många av de arter som minskat i antal och utbredning knutna till just detta. Om inte förlusten av biologisk mångfald i jordbrukslandskapet bryts kan detta leda till att Sverige inte lever upp till konventionen om biologisk mångfald och till att viktiga ekosystemtjänster i jordbrukslandskapet som pollination och

In the 1860s, Sweden’s harsh religious legislation was liberalised. The Dissenter Act legalised conversions to other Christian denominations, but it put in place many obstacles to leaving the established church, and many of the legal restrictions were obviously anti-Catholic in intent. Anti-Catholic sentiment was also expressed in conjunction with the legislative proposals and parliamentary debate

Individuals with autism spectrum disorder (ASD) experience high levels of anxiety symptomatology with an estimated prevalence rate of anxiety disorders as high as 40 %. It is likely that anxiety is prominent in individuals with ASD throughout the life-span and that factors such as age, IQ, and ASD symptoms may influence the rates, symptoms, or anxiety subtypes. The high comorbidity rate of anxiety

Short comparative study of Vilhelm Ekelund and Emanuel Swedenborg

Institutions (including regulations) are constitutive elements of innovation systems, and therefore cornerstones of innovation policy. Focusing on (soft and hard) regulation, the paper identifies the most salient regulatory areas from the perspective of the innovation system. When asking about the effects of regulation on innovation, the paper argues that there are three key issues that need caref

Within the newly decided scheme for CE-marking of cables1 a full-scale fire test for cables (prEN503992) has been introduced. The new test measures heat and smoke production rates and flame spread and in some cases requires large amounts of cables. In the project presented here a modelling tool was developed to predict full-scale results using data from the small-scale fire test Cone Calorimeter.

We analyze the channel capacity of multiple-input multiple-output (MIMO) systems in frequcncy selective channels, with channel knowledge at the transmitter side. An optimum transmission scheme uses Shannon's principle of waterfilling jointly in the frequency and the spatial domain. However, we show in this paper that the largest gain by using waterfilling resides in the spatial domain, and that th
