The paper considers period overruns in control tasks with variationsin execution time (or response time). A simple model is used, wherethe input and output operations are assumed to be time-triggered,and the execution-time distribution of the task is assumed to beknown. Three overrun strategies, called Abort, Skip, andQueue, are modeled as discrete-time jump linear systems and areanalyzed with reg

A fully integrated digital PLL used as a clock multiplying circuit is designed and manufactured. The PLL has no off-chip components and it is made from standard cells found in most digital standard cell libraries. It is therefore portable between processes as an IP-block. Using a 0.35 μm standard CMOS process and a 3.0 V supply voltage, the PLL has a frequency range of 152 MHz to 366 MHz and occup

Philosophers of science have often favoured reductive approaches to how-possibly explanation. This article identifies three alternative conceptions making how-possibly explanation an interesting phenomenon in its own right. The first variety approaches “how possibly X?” by showing that X is not epistemically impossible. This can sometimes be achieved by removing misunderstandings concerning the

The family with the elderly and the home help workers’ team constitute two organisations, which meet in the care work. In this context the family is extended and often constitute not only members from the nuclear family but also other members of the network of relatives, whom take part in the care of the elderly. The extended family may in some cases include four generations (Finch & Mason, 19

Green production systems requires efficient production and low use of resources such as energy, material etc. To achieve this, there is a need for further development of continuous improvement tools in the “lean and green” area. This work deals with environmental value stream mapping (Environmental-VSM), which has been applied in two case studies at Volvo Penta Vara and Volvo Construction Equipmen

Popular Abstract in Swedish Människans arvsmassa består av DNA. DNA i sin tur består av nukleotiderna A, T, G och C som i olika kombinationer bygger upp våra gener. Människans "genom" (hela arvsmassa) består av uppåt 100 000 gener och varje gen kodar för ett protein som i sin tur är byggstenarna i våra kroppar. Eftersom DNA är en oerhört lång molekyl och cellerna är väldigt små (ca 10 micrometer) Chromosomal translocations commonly result in the production of fusion genes and the fusion genes are often tumor-type specific. In myxoid and round cell liposarcomas (MLS/RCLS), almost 95% of the cases carry a t(12;16)(q13;p11). In the remaining 5% of the MLS/RCLS tumors, another translocation and fusion gene can be found, i.e. the t(12;22)(q13;q12). These translocations fuse CHOP on chromosome 1

A general survey of the history, architecture and inventories of Lund cathedral from the beginning to the present time.

This paper discusses some trends in critical theory and activist aesthetics in contemporary feminist performing arts in Sweden. The 2000s have witnessed at least two “turns” in feminist theory, namely the affective turn and the social, or as it is called here, the solidarity turn. The status of poststructuralist theory has been widely debated and Marxist, class-based analyses have returned to the

A super-regenerative oscillator to be used as a receiver for ultra wideband impulse radio signals is demonstrated for the V-band (50-75 GHz). The study is based on experimental and simulated results using a gated tunnel diode based super-regenerative oscillator, which is used as the core of a super-regenerative receiver. Simulated pulse error rates for an impulse radio signal that is modulated by
