This paper presents a fast, pipelined and scalable hardware architecture for inverting complex valued matrices. The matrix inversion algorithm involves, a QR-factorization based on the squared Givens rotations algorithm, the application of a recurrence algorithm for inversion of an upper triangular matrix R, and a matrix multiplication of R-1 with Q. We show that traditional triangular
The number of electrically driven loads in a modern vehicle is constantly increasing. Many loads that former were mechanically driven will in the future be driven by electricity. This implies that a number of electronic systems have to be packed together in the limited space in a vehicle. When different electronic systems are placed close to each other, there is always a risk for electromagnetic i
The aim of this thesis was to elucidate the mechanisms by which planktivorous fish can affect planktonic communities in lakes and how they may affect benthic communities through their effects on planktonic communities. In a laboratory experiment, nutrients released by fish increased algal biomass and altered phytoplankton community structure, suggesting that fish can affect phytoplankton by direct
Offers various perspectives on the Swedish regional production turn during the 1990s and 2000s.
The Amphorae was a common container for transportation of especially liquid goods in the Greco-Roman world. There are several known production sites of these vessels around the Mediterranean. The shapes of the different amphorae have been amply described and grouped according to different systems. There has also been several works describing the fabric of the vessels and also attempts to link vess

Popular Abstract in English Proteins are a class of biological macromolecules that perform countless fundamental and diverse functions in living organisms. Chemically speaking, they are polymers built out of monomeric units called amino acids. All biological proteins are constructed out of 20 different amino-acid types. To form protein molecules, amino acids are linked together in a linear chain lThe minimum free energy state of a protein (the native state) is encoded by its amino-acid sequence. Due to the many torsional degrees of freedom (DOF) available to a polypeptide chain, a vast number of conformations is possible. Therefore, to predict the native state of a protein directly from sequence, a computer algorithm must evaluate a large number of possible conformations using accurate sco
Widespread presence of toxic and persistent pollutants in the environment, even at low concentrations, causes risks of adverse effects to human health and the ecosystem. Biological methods for treatment of water streams and removal of persistent pollutants are of great interest due to their simplicity, low cost, and mild operational conditions without harmful by-products. The purpose of this resea
