Preliminary results from a study about voice alarms are presented in this paper. The purpose of the study is to explore both how messages should be worded and how they should be presented. The paper focuses on an introductory questionnaire study at an IKEA store and unannounced evacuation experiments at Lund University. The results of these activities suggest that it is preferable to mention the w

Popular Abstract in Swedish Populära tidskrifter och flertalet debattörer har alltsedan 80-talet hävdat att privatisering leder automatiskt till en förbättring av företagets effektivitet. På grund av dessa diskussioner har man litat mycket på marknadskrafter, då man trott att dessa krafter kan ombilda organisationer med goda effekter. Avhandlingen är en kritik mot dessa ansatser. Författaren försöThe majority of research on privatisation has been driven by, inter alia, economics. Some economists have argued that private ownership introduces capital market pressures into inefficient state bureaucracies. Private property rights are expected to maximise the incentives for management to achieve a high level of production efficiency. The argument put forward in this research is that in so far a

By virtue of their geometry, uniform circular arrays (UCAs) are ideally suited to provide 360 degrees of coverage in the azimuthal plane. However, in a correlated signal environment, the well-known technique of spatial smoothing to mitigate the signal cancellation effect as seen in an optimum beamformer will not work since this technique is applicable only to uniform linear arrays. We show how the

Benchmarking is a powerful strategic tool used to assist decision makers to improve the quality and effectiveness of organisational processes. Even in Higher Education nowadays, benchmarking is used as a tool for quality enhancement. This paper explores the results from a study on international benchmarking on elearning in higher education. The study explicitly showed the value and impact of the m

The paper presents some preliminaryresults on dynamic scheduling of model predictive controllers (MPCs).In an MPC, the control signal is obtained by on-line optimization of acost function, and the MPC task may experience very large variationsin execution time from sample to sample. Unique to this application,the cost function offers an explicit, on-line quality-of-servicemeasure for the task. Base

We evaluate the performance of resonant tunneling permeable base transistors (RT-PBTs) by numerical simulations. Since the current is limited by the barriers, a design with a low doping level around the embedded gate wires is chosen to improve the transconductance. We evaluate the influence of the various geometrical parameters, to optimize the design for high frequency operation. We obtain a perf

Packaging is becoming increasingly important from a marketing as well as logistics perspective, particularly for actors in consumer product supply chains. However, the role of packaging in creating or contributing to the competitive advantage of a company or a whole supply chain is still unexplored to a large extent. This is even the case in businesses where research has shown the benefits of cons

Dynamics of spontaneous decay and corresponding emission spectrum areexactly treated for a system of two identical two-level atoms in 1D.Just a one-dimensional case is considered in order to maximally extractan information on mutual influence of spatially remote atoms through theradiation field. As a result, an effect is revealed and considered indetail that there exist stable (metastable) entangl

The European Spallation Source (ESS) is the European common effort in designing and building a next generation large-scale user facility for studies of the structure and dynamics of materials. The proposed schematic layout of the ESS facility is based on a linear driver (linac) directing the proton beam (5 MW of 2.5 GeV) of 2.8 ms long pulses with a 20 Hz on a tungsten target where neutrons are pr
