On TPC decoding during soft handover in WCDMA

It has been shown in field trials as well as in system simulations that the overall system performance heavily depends on good TPC decoding in the mobile terminals during soft handover in VVCDMA. In this paper we show criteria on the TPC decoding performance in soft handover in the mobile terminal in order to have a stable up-link power control loop in WCDMA. We also show that the traditional "OR"

Pairwise Kidney Exchange with Blood-Group Incompatibility

Kidney transplants across the blood-group barrier are medically feasible even if blood-group compatibility is preferred from a medical point of view. However, these types of transplants are motivated by the fact that they help in increasing the number of kidney transplants with living donors. This paper investigates priority matchings in a pairwise kidney exchange problem where blood-group incompa

Value Creation in PSS Design Through Product and Packaging Innovation Processes

Over the years consumer packaging has become increasingly important as a value-adding element, since packages shape the consumer’s experience with the product during use, as well as accelerate the purchase decision. From a prod-uct/service system perspective, the strategic benefits of viewing packaging as a central value carrier are evident. To consumers, the product and its packaging are often pe

Model for Print Quality Evaluation of Hybrid Printer Matter

Pressure on reducing prices and a market demand for customisation and shorter production runs give cause for investigating alternatives to conventional printing. Traditional technologies, such as flexography and offset, are all using static printing forms, while a digital printing unit prints information directly from the data file. Hence, the latter alternative makes it possible to produce short

Investigation method for cascading effects between critical infrastructures

This paper presents an investigation method for studying cascading effects in incidents, which is to some extent lacking in the scientific literature. Several incident investigation methods are reviewed and used to influence the presented method. The usefulness of the method is demonstrated in a case study for a recent event in Sweden, a severe flooding event in the city of Malmö in south of Swede

”Modul 1 Skogsbruk”. Klimatet och skogen – underlag för nationell forskning

Behovet av ny kunskap i anslutning till klimatförändringen är enormt. Det behövs ny kunskap om hur • klimatet kan komma att utvecklas. • skogsekosystemet kan komma att utvecklas. • dessa system interagerar. Detta kunskapsuppbyggande är högst angeläget att påbörja men kommer att ta tid. Många beslut inom skogsbruket måste fattas redan idag utan tillgång till forskningsresultaten. Man tvingas alltså

On suboptimum component decoding for product codes

The performance and convergence behavior of the iterative schemes for decoding two-dimensional product codes are investigated. The decoding trajectories of the extrinsic and the a posteriori information are used as a main tool for predicting and explaining the behavior of the iterative decoding process. The component-wise optimal BCJR decoder is compared to the suboptimal max-log-MAP decoder and t

Three Ways to Mount Distinguishing Attacks on Irregularly Clocked Stream Ciphers

Many stream ciphers use irregular clocking to introduce nonlinearity to the keystream. We present three distinguishers on irregularly clocked linear feedback shift registers. The general idea used is to find suitable linear combinations of keystream bits, here called samples, that are drawn from a biased distribution. We describe how to place windows around the estimated positions around members
