To be able to explore different signal types and processing techniques, apt for sediment mapping, programmable, fully digital profiling systems has been built and tested. The systema are designed to be deployed also at small water depths from small boats, without special handling equipment. The usable frequency band is 100-25000 Hz, limited to approximately 2-10 kHz depending on the projector used

Purpose of this paper
The purpose is twofold: to map the reviewers’ perspective of evaluation of case based logistics and supply chain management research; and to develop a framework with all criteria needed to design, conduct, and present rigorous case study research. This framework can be used by both researchers and reviewers.

Peoples' relations to animals and their various roles took many different expressions in the pre-Christian era. In certain contexts animals had practical functions, but others they also had symbolic values. Domsticated animals were a kind of life style metaphors in grave rituals. Wild animals and transformation between humans and animals in pictorial images signified social identity. The archaeolo

In modern chemical process industry, process state transitions, or grade changes, are common operations. Frequent production changes increase the focus on efficient operator support for such procedures. The aims of a grade change may be complex, and sometimes conflicting.Fast transitions are desirable in order to minimize production loss. There may also be safety aspects that must be considered, i

In this paper, a generic electromagnetic model is utilized for arbitrary multiport antennas e.g., vector sensors applied in DOA estimation, which was exploited for the statistical analysis of DOA and polarization estimation. By utilizing the spherical vector wave expansion of the electromagnetic field to completely characterize the multiport antennas a general framework for modelling an antenna co

Following the theme of this monograph, this paper discusses a dialectic we perceive to subsist between meaningful use and reflection upon use. This dialectic between experiencing use and reflecting upon experiencing use (or thinking, and thinking about thinking) may be considered in the following way. Each of these elements is subject to change. As reflection triggers change in use, and such chang

‘Safety pays’ is a phrase commonly used. But, when it comes to putting that concept into practice, very few are actually successful at it. Reasons given include: it is costly or it is a waste of time or it is not the main cause of failure. However the real problem is that there is not enough guidance as to how to improve safety performance on site. Traditional measurement approaches include accide

Length and area regularization are commonplace for inverse problems today. It has however turned out to be much more difficult to incorporate a curvature prior. In this paper we propose several improvements to a recently proposed framework based on global optimization. We identify and solve an issue with extraneous arcs in the original formulation by introducing region consistency constraints. The

The use of coarse-grain reconfigurable architectures (CGRA) is a suitable alternative for hardware acceleration in many application areas, including digital holographic imaging. In this paper, we propose a CGRA-based system with an array of processing and memory cells, which communicate using a local and a global communication network, and a stream memory controller to manage data transfers to ext

Structures of Architectural Heritage are constantly exposed to natural and human-made threats that can compromise their cultural and artistic values. This is the case of the Roman city of Pompeii, whose preserving conditions nowadays are so critical to let a group of Unesco-appointed experts consider the possible inscription of the property on the list of “World Heritage in Danger”. In this respec

Absorption microspectrophotometry has been shown to be of considerable help to probe crystalline proteins containing chromophores, metal centres, or coloured substrates/co-factors. Absorption spectra contribute to the proper interpretation of crystallographic structures, especially when transient intermediate states are studied. Here it is shown that fluorescence microspectrophotometry might also

A method for calculating the wave load induced fatigue damage accumulated by a vessel sailing along the North Atlantic route (NAr) is presented. This method is based on the Palmgren-Miner additive rule and the rainflow cycle (RFC) count. For simplicity, the load the vessel experiences is assumed to be proportional to the encountered significant wave height process, H-s. The asymptotically normal c
