A new low-order and causal twisted-pair cable model for the copper access network is derived. From the serial resistance of the widely used, but non-causal, BT0 model, the serial inductance is computed via the Hilbert transform. By doing so, a causal cable model is obtained containing fewer parameters compared to the BT0 model. The deviation between the two models is evaluated for the standardized

Creativity has become a key issue for managers and scholars alike. Creativity, however, is a complex and multi-levelled phenomenon. The significance of creativity and its complexity beg the question of how managers organise for creativity and how they address tensions linked to their organising attempts. Based on an interpretive methodology the book investigates these questions and explores differ

This paper presents theory and algorithms for covariance analysis and stochastic realization without any minimality condition imposed. Also without any minimality conditions, we show that several properties of covariance factorization and positive realness hold. The results are significant for validation in system identification of state-space models from finite input-output sequences. Using the R

Popular Abstract in Swedish Avhandlingen behandlar välfärd med fokus på internationell mobilitet och immobilitet. Den tar avstamp i två olika konceptuliseringar av organiseringen av vardagen i relation till nationalstaten: en som konceptualiserar vardagslivet som relativt mobilt och föränderligt över nationalstatliga gränser, och en som konceptualiserar det som relativt immobilt och oföränderligt The dissertation considers welfare with regard to international mobility and immobility. It addresses a tension between two different conceptualisations of the organisation of everyday life with regard to nation-states: one that views everyday life as relatively mobile across nation-state borders and boundaries, and another that treats everyday life as relatively confined within such limits. The o

Popular Abstract in Swedish I min avhandling har jag valt att studera kväveoxid (nitric oxide, NO) i de delar av det centrala nervsystemet (CNS), dvs hjärna och ryggmärg, som är inblandade i styrningen av vattenbalans och vattenkastning (miktion). NO, en gas och 1987 identifierad som en fysiologisk signalmolekyl bla i CNS, kan dock ej studeras i nervceller pga sin korta livslängd. Den molekyl jag The role of nitric oxide (NO) in the central control of water balance and micturition has not yet been established. In the present thesis, where female rats were used, neuronal NO synthase (nNOS) distribution was studied in structures of the central nervous system known to be associated with the above mentioned control. Moreover, the concert action of a NOS inhibitor and oxytocin (OT), intrathecal

Safe languages like Java provide a much more programmerfriendly environment than the low-level languages in which real-time and embedded software have traditionally been implemented. However, an obstacle for widespread use of Java in control applications has been the predictability and real-time performance of garbage collection, and the cumbersome memory management associated with RTSJ NoHeapReal

Convergence in the electronic security industry entails the meeting of two very different business cultures, which is currently manifesting itself in the form a knowledge gap. In view of this, the crucial strategic resources needed to succeed in the converged electronic security market of tomorrow will be a combination of competences, ca- pabilities and skills sets – or knowledge, in short – drawn

Atmospheric aerosol particles have been sampled near a Los Angeles freeway and analyzed by proton-induced X-ray emission, PIXE, as a sulfur baseline study in September 1974 before 1975-model automobiles, equipped with catalytic emission control devices, appeared in large numbers. The sampling plan was optimized according to the requirements of X-ray analysis techniques, fluctuations in air flow ac
