Approaching Logistics - Exploring Complexity Approaches to Move Beyond Systems Approach

Logistics is being given increased attention in companies and in research, and is gaining strategic importance as supply chains or, more aptly named, supply networks are the realm of today. For both researchers and practitioners in the field of logistics one of the fundamental concepts is the systems approach. As many researchers proclaim, to understand logistics you need to understand the concept

Factors influencing sense of coherence in a Human Services organisation

Salutogenetic factors (Antonovsky, 1987) at rehabilitation sections in Swedish Social Insurance offices were investigated in 2 studies. Study 1 (N=158) surveyed creative/stagnated climate (Ekvall, 1988), leadership of immediate superior (Ekvall&Arvonen, 1991), and sense of coherence (Antonovsky, 1993), here modified for the work place (W-SOC). A multiple regression (p< .001) showed that creati

Synthesis of mesoporous cerium dioxide thin films with high crystallinity

Thin films of crystalline mesoporous cerium dioxide were prepared by using a template of a copolymer surfactant (Pluronics 123) at ambient conditions in ethanol. The synthesised ceria was produced via a direct calcination step, without using a gelling stage. The precipitated CeO2 matrix was crystalline with a high surface area. The solution height over the synthesis vessel before the calcination s

Non-Visual Haptic Interaction Design - Guidelines and Applications

This dissertation has three cornerstones: * Haptics * Human-Computer Interaction (HCI) * Blind Users Haptics deals with controlling human movements and getting feedback through the sense of touch. A haptic interface transmits forces to a person’s hand or fingers in a way that mimics the sensation of touching real objects. Virtual haptic touch can be particularly useful for people with visual i

Ultraviolet Spectral Analyses of HgMn Stars

Almost a decade after the last observations were performed by theInternational Ultraviolet Explorer (IUE) satellite its rich archivescomprise a wealth of opportunity for the stellar astronomer, inparticular when exploring large samples of stars. We have inaugurated anexploration into the nature of chemically peculiar stars through thoseelemental abundance studies which are best carried out at UVwa

Overview of vehicle-to-vehicle radio channel measurements for collision avoidance applications

In this paper we present an overview of a vehicle-to-vehicle radio channel measurement campaign at 5.6GHz. The selected measurement scenarios are based on important safety-related applications. We explain why these scenarios are interesting from the aspect of radio propagation. Further we describe the power-delay profile and the Doppler spectral density of two situations especially suitable for co
