Popular Abstract in Swedish ``Att fela ör mönskligt...'' är början på en sentens som antyder att det krävs någit ytöver det mänskliga för att korrigera fel; sanningen är att det är lika naturligt för människan at korrigera fel som det är att fela, vilket belyses i detta stycke. Trots ett flertal skrivfel är innebörden av texten entydig. Detta beror naturligtvis på att meningsfull svensk text svaraModern communication systems strive to achieve reliable and efficient information transmission and storage with affordable complexity. Hence, efficient low-complexity channel codes providing low probabilities for erroneous receptions are needed. Interpreting codes as graphs and graphs as codes opens new perspectives for constructing such channel codes. Low-density parity-check (LDPC) codes are one

The stepwise commitment from hematopoietic stem cells in the bone marrow to T lymphocyte-restricted progenitors in the thymus represents a paradigm for understanding the requirement for distinct extrinsic cues during different stages of lineage restriction from multipotent to lineage-restricted progenitors. However, the commitment stage at which progenitors migrate from the bone marrow to the thym

The twentieth century was a century of liturgical reforms. Every century has spent great resources on the liturgy, but hardly any other century has spent so much effort on changing it as the twentieth. Yet no-one seems content with what has been achieved. Five motives for liturgical reform are discussed: repristination, active participation, pastoral adaptation, ecumenical convergence, and the sim

In this paper, a control system for an advanced prosthesis is proposed and has been investigated in two different biological systems: (1) the spinal withdrawal reflex system of a rat and (2) voluntary movements in two human males: one normal subject and one subject with a traumatic hand amputation. The small-animal system was used as a model system to test different processing methods for the pros

In Sweden a fundamental development has recently taken place in the training of future senior fire brigade officers. There are two main changes: the training period has been substantially increased and the theoretical part upgraded to university curriculum level with final requirements corresponding to a university undergraduate degree. The new educational system reflects the changing and expandin

It is well known that user proximity introduces absorption and impedance mismatch losses that severely degrade multiple-input multiple-output (MIMO) performance of handset antennas. In this work, we experimentally verified the potential of adaptive impedance matching (AIM) to mitigate user interaction effects and identified the main AIM gain mechanism in realistic systems. A practical setup includ

The finite element method is used to analyze the stability of a cantilever column resting on elastic foundation and subjected to an eccentric slave load at its free end. The analysis has been conducted according to Bernoulli-Euler and Timoshenko beam theories. Effects of the mass offset, coupling effects and damping has been taken into account.
