Sorption isotherms (moisture content as a function of relative humidity (RH) at equilibrium) are an important tool in designing buildings to limit moisture related problems. Normally only a single sorption curve is used so that each moisture content uniquely corresponds to one RH. Sometimes two curves are used, one curve for absorption and one for desorption, as it is well known that sorption has

Structure from sound can be phrased as the problem of determining the position of a number of microphones and a number of sound sources given only the recorded sounds. In this paper we study minimal structure from sound problems in both TOA (time of arrival) and TDOA (time difference of arrival) settings with collinear constraints on e.g. the microphone positions. Three such minimal cases are anal

Popular Abstract in Swedish Cellulosa och stärkelse är naturligt förekommande polysackarider, som är uppbyggda av långa rader av flera tusen sammanbundna glukosmolekyler. De är biologiskt nedbrytbara, billiga och dessutom förnyelsebara, och används mycket som råvaror i läkemedels-, livsmedels-, textil-, pappers- och byggnadsindustrin. För att cellulosa och stärkelse ska kunna användas industrelltCellulose and starch are non-toxic, biodegradable and modifiable polymers. These properties have made them increasingly important in industrial products e. g. in pharmaceutical applications and in technical dispersions. By chemical modification of these polymers the physical and chemical properties of the polymer can be adjusted to suit a certain area of application. The characteristics of modifie

The design of an ultra-low-leakage latch, suitable for subthreshold standard-cell based memories in 65nm CMOS is presented. Various latch architectures are compared in terms of leakage, area and speed. The most leakage-efficient architecture is optimized by transistor stacking and channel length stretching. The final design is supplemented with a 3-state output buffer to provide low-leakage read f

Gold nanoelectrodes with gaps of less than 10 nm were formed by conventional E-beam lithography on silicon substrates covered by Al2O3. Molecular films were deposited on the electrodes by Langmuir-Shaefer technique. The I-V curves of such systems show a suppressed conductance indicating a correlated electron tunnelling through the system. All measurements were made at room temperature.

Various transport phenomena in conjunction with chemical reactions are strongly affected by reformer configurations and properties of involved porous catalyst layers. The considered composite duct is relevant for a methane steam reformer and consists of a porous layer for the catalytic chemical reactions, the fuel gas flow duct and solid plate. In this paper, a fully three-dimensional calculation

In this paper we present an algorithm for finding low-weight multiples of polynomials over the binary field using coding theoretic methods. The code defined by the public polynomial is cyclic, allowing an attacker to search for any shift of the sought codeword. Therefore, a code with higher length and dimension is used, having a larger number of low-weight codewords. Additionally, since the degree of

A stochastic model based on a probability density function (PDF) approach was developed for the investigation of spark ignition (SI) engine knock conditions. The model is based on a two zone model, where the burned and unburned gases are described as stochastic reactors, and the movement of the turbulent flame front is expressed with a Wiebe function. Using a stochastic particle ensemble to repres

Increasing soft error rates for semiconductor devices manu- factured in later technologies enforces the use of fault tolerant techniques such as Roll-back Recovery with Checkpointing (RRC). However, RRC introduces time overhead that increases the completion (execution) time. For non-real-time systems, research have focused on optimizing RRC and shown that it is possible to find the optimal number

The propositions in this chapter are to a large extent drawn from the thesis Metaphors and norms – understanding copyright law in a digital society (Larsson 2011b), however with some important complements, not least concerning the implications of categorisation. The chapter is explorative in bringing findings from cognitive linguistics into the quite common socio-legal task of studying norms. Its
