The Nordic countries have often been seen as “fore-runners” of energy efficiency in buildings – in both the implementation of policy instruments and the evaluation of effects. Since the 1970s, the Nordic countries have introduced a range of policy instruments for energy conservation in buildings. The choice of instruments and experiences, however differs between countries. The aim of this study is

The problem of estimating a discrete-time stochastic signal which is corrupted by additive white measurement noise is discussed. How the stationary solution to the fixed-lag smoothing problem can be obtained is shown. The first step is to construct an innovation model for the process. It is then shown how the fixed-lag smoother can be determined from the polynomials in the transfer function of the

Prostate-specific antigen (PSA) and human glandular kallikrein 2 (hK2) are glandular kallikreins secreted by the prostate gland. Both enzymes are synthesized with a propeptide that is supposedly cleaved off in the prostate to yield the mature forms found in semen. We have purified and characterised recombinant PSA and hK2 produced in eucaryotic cells. Recombinant PSA was recovered as a zymogen and

Stricter Swedish building regulations require a moisture-safety design process to be carried out before houses are built. In order to predict moisture-critical conditions, a properly verified, user-friendly and reliable calculation tool that could be used in this design phase, is required.This paper initially presents a blind method that could be used in order to verify heat and moisture calculati

This paper describes a search procedure to discover optimal feature sets for dependency parsers. The search applies to the shift–reduce algorithm and the feature sets are extracted from the parser configuration. The initial feature is limited to the first word in the input queue. Then, the procedure uses a set of rules founded on the assumption that topological neighbors of significant features in

This paper presents a fast, interactive and easily modifiable software tool for robust PID design. The Matlab based program is supposed to give people with moderate knowledge on PID control a possibility to learn more and also be a future part of an autotuner. The PID design is made by minimizing the integrated absolute error value during a load disturbance on the process input. The optimization i

Målsättningen med detta projekt var att utveckla ett praktiskt och resurssnålt pedagogiskt instrument för att öka den kontinuerliga återkopplingen och studentaktiveringen i stora föreläsningskurser. Först konsulterades litteraturen när det gäller kunskapen om föreläsningar och återkoppling till stora studentgrupper. Baserat på detta, och på författarnas tidigare erfarenheter, utvecklades sedan ett
