Determination of over current protection thresholds for class D audio amplifiers
Monolithic class-D audio amplifiers typically feature built-in over current protection circuitry that shuts down the amplifier in case of a short circuit on the output speaker terminals. To minimize cost, the threshold at which the device shuts down must be set just above the maximum current that can flow in the loudspeaker during normal operation. The current required is determined by the complex
Current issues in pictorial semiotics. Lecture one: The Quadrature of the Hermeneutic Circle.
The first lecture will present pictorial semiotics within the framework of general semiotic theory. It will construe semiotics as a particular point of view taken on everything which is human or, more generally, endowed with life, rather than simply the continuation of the mixed or separate doctrines due to Saussure and Peirce. The historical part will describe briefly the development of pictorial

Thick screens perforated with a periodic array of apertures with arbitrary cross-section
A plane wave impinges on a perfectly conducting thick screen perforated with a periodic array of apertures with arbitrary cross-section. The transmission and reflection coefficients are determined by a mode matching technique, earlier used by other authors for the case where the apertures have the geometry of a classical waveguide. The fields outside the screen are expanded in plane waves, while t

Parallel and Distributed Graph Cuts
Graph cuts methods are at the core of many state-of-the-art algorithms in computer vision due to their efficiency in computing globally optimal solutions. In this paper, we solve the maximum flow/minimum cut problem in parallel by splitting the graph into multiple parts and hence, further increase the computational efficacy of graph cuts. Optimality of the solution is guaranteed by dual decomposit
Model Curriculum for a Bachelor of Science Program in Business Information Systems Design (BISD 2010)
Commentators on Information Systems (IS) education have urged the IS community to develop new and alternative IS curricula. The IS 2002 model curriculum has recently been revised. The new IS 2010 curriculum guidelines for undergraduate degree programs in Information Systems [Topi et al. 2010] has a curriculum structure to accommodate the education of several different professional roles within IS.
Signs of resistance? Swedish probation officers’ attitudes towards risk assessments
The Swedish Prison and Probation Service has been influenced by the „What Works‟ agenda since the late 1990‟s and an orientation towards risk and risk management has gradually become visible in the organization. But there is, within the probation service, a discrepancy between two types of logics – an organizational logic and a professional logic. Although guidelines prescribe the use of risk-asse
Electromagnetic scattering by a bounded obstacle in a parallel plate waveguide
This paper concerns scattering of an electromagnetic wave by a bounded object located inside a parallel plate waveguide. The exciting field in the waveguide is either an arbitrary source located at a finite distance from the obstacle or a plane wave generated in the far zone. In the latter case, the generating field corresponds to the lowest propagating mode (TEM) in the waveguide. The analytic tr
Challenges in Market-Driven Requirements Engineering - an Industrial Interview Study
Requirements engineering for commercial off-the-shelf software packages entails special challenges. This paper presents preliminary results from an empirical study investigating these challenges through a qualitative approach using semi-structured interviews. The survey is exploratory with the objective of eliciting relevant topics for further research. Seven employees at five software companies w
Laser capture microdissection (LCM) and whole genome amplification (WGA) of DNA from normal breast tissue - optimization for genome wide array analyses.
Background Laser capture microdissection (LCM) can be applied to tissues where cells of interest are distinguishable from surrounding cell populations. Here, we have optimized LCM for fresh frozen normal breast tissue where large amounts of fat can cause problems during microdissection. Since the amount of DNA needed for genome wide analyses, such as single nucleotide polymorphism (SNP) arrays, is

Impact of Functional Models in a Decision Context of Critical Infrastructure Vulnerability
Critical infrastructures provide essential services for the functioning of the society, and disruption of these services can lead to large-scale consequences. Hence, it is of utmost importance to analyze the vulnerability of critical infrastructures and use the results to guide decisions of improving their robustness towards strains. Since real-life critical infrastructures can be regarded as comp

Characterization of the gene for prostate-specific antigen, a human glandular kallikrein
The gene for the human glandular kallikrein, prostate-specific antigen, has been cloned. The sequence of 7130 nucleotides encompassing the gene and 633 bp of 5' and 639 bp of 3' flanking DNA has been determined. The translation initiation site was slightly heterogeneous, yielding 5' non-translated leader sequences of 41 and 35 bp. The gene is divided into five exons, with introns located at positi
Corners in Plasticity - Koiter's Theory Revisited
A general theory for plastic loading at corners is presented that includes Koiter's theory as a special case. This theory is derived within a thermodynamic framework and includes non-associated as well as associated theory. The non-associated theory even allows the number of potential functions to differ from the number of yield functions. The properties of the matrix of plastic moduli as well as
