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
The increasingcost for System-on-Chip (SOC) testing is mainly due to the hugetest data volumes that lead to long test application time andrequire large automatic test equipment (ATE) memory. Testcompression and test sharing have been proposed to reduce the testdata volume, while test infrastructure and concurrent testscheduling have been developed to reduce the test application time.In this work w
Ultrasonic Additive Manufacturing (UAM), or Ultrasonic Consolidation as it is also referred, is a hybrid form of manufacture, primarily for metal components. The unique nature of the process permits extremely novel functionality to be realised such as multi-material structures with embedded componentry. UAM has been subject to research and investigation at Loughborough University since 2001. This
Transitions towards sustainability are urgently needed to address the interconnected challenges of economic development, ecological integrity, and social justice, from local to global scales. Around the world, collaborative science-society initiatives are forming to conduct experiments in support of sustainability transitions. Such experiments, if carefully designed, provide significant learning o
We consider a type of optimal switching problems with non-uniform execution delays and ramping. Such problems frequently occur in the operation of economical and engineering systems. We first provide a solution to the problem by applying a probabilistic method. The main contribution is, however, a scheme for approximating the optimal control by limiting the information in the state-feedback. In a
