A self-assessment framework for finding improvement objectives with ISO/IEC 29119 test standard

One of the latest additions in defining the test process is the upcoming ISO/IEC 29119 standard, which aims to define a universally applicable generic test process model. However, currently the standard does not offer any support for the adoption process of the model. In this paper, we present our framework, which aims to combine a maturity level-based approach with the standard process. Our objec

Design space exploration for optimal memory mapping of data and instructions in multimedia applications to scratch-pad memories

In this paper, we propose a new methodology for optimal memory mapping of data and instructions to Scratch-Pad Memories (SPM). In the mapping process, we optimize, as the main priority, the number of memory accesses to minimize power consumption. Minimization of external memory accesses lowers switching activity and therefore power consumption. The optimization is done by finding Pareto-points, us

The Theory of the Propagation of TEM-Pulses in Dispersive Bi-Isotropic Slabs

A survey of the theory of propagation of transient transverse electromagnetic waves in temporally dispersive, bi-isotropic slabs is given, and a novel wave splitting, which completely separates right-going and left-going waves in the dispersive medium, is proposed. The new approach leads to a simple scattering relation in terms of wave propagators and single-interface scattering operators only. Th

Physical limitations on D/Q for antennas

In this paper, physical limitations on the directivity D and Q-factor Q are derived for antennas of arbitrary shape. The quotient D/Q is shown to be bounded from above by the antenna volume and certain shape coefficients in terms of the eigenvalues of the high-contrast polarizability dyadic. The theory is exemplified by numerical results for the half-wave antenna with astonishing agreement.

Investigating upstream versus downstream decision-making in software product management

Decision outcomes and their lead times are critical in product management, as the market success of a product may strongly depend on the both the decisions themselves and their timing in relation to the market and competitors. This paper presents an investigation of one particular industrial case study data set by comparing upstream scoping decisions with downstream change decision. The results in
