In this paper, the thermal impact of using different steel laminations in the stator and the rotor of a permanentmagnet assisted synchronous reluctance machine designed for an automotive application is studied. In this regard, two main parameters of the steel lamination materials, thickness and amount of alloy content in weight percent, are studied. Frequency characteristics of the iron losses of

In an organization where the safety level is high and incidents and serious accidents are very rare, a steady erosion of safety awareness and protective measures can occur, especially when productive demands rise. Thus, it is important to continuously identify and monitor aspects in the organization that can affect work performance and safety. In an ongoing joint research project between the LFV G

Our problem is how to design, with the use of distance and ICT, an appropriate academic context for learning, for students with no previous knowledge of this context. Our aim is to analyse and describe the learner’s relation to the object of his/her studies as part of his/her relation to the learning activity. By using a combination of a phenomenographic approach and activity system theory, we ana

Title: Along one and the same road - a study of the people behind some hand written song books from around the turn of the 19th century. It is based on some hand written songbooks found in homes along the small byroad in Kruse, Alva, Gotland. My own connection to the place is that I was born in one of these houses. During the summer of 2008 interviews were made with four people who live or have li

The pseudo-rapidity dependence of the elliptic flow at various excitation energies measured by the PHOBOS Collaboration in Au+Au collisions at RHIC is one of the surprising results that has not been explained before in terms of hydrodynamical models. Here we show that these data are in agreement with theoretical predictions based on perfect fluid hydrodynamics. We also show that these PHOBOS data

This paper presents a method to relax Dynamic Programming. The methodmakes it possible to findsuboptimal solutions with known error bounds to hard problems.The bounds are chosen by the user, who can then effectively trade-offbetween solution time and accuracy. Several examples from differentdomains where the method is highly useful are presented.

Delays and cost overruns are frequent problems in the construction industries of both developed and developing countries. Studies aimed at identifying the causes are often undertaken with just a broad appreciation of the construction process and frequently do not deal with multicultural issues when considering the reasons for overruns. The paper critically reviews existing attempts to uncover the

We consider a link serving multiple service classes. We evaluate the properties of the link admission control policies that are obtained from an efficient scheme proposed by Krishnan and Hubner (1997). The Krishnan and Hubner approach suggests efficient calculations of state-dependent routing criteria for multi-rate networks through state-space aggregation. Through simple examples we show that it

In this paper novel theory to automate shape modelling is described. The main idea is to develop a theory that is intrinsically defined for curves, as opposed to a finite sample of points along the curves. The major problem here is to define shape variation in a way that is invariant to curve parametrisations. Instead of representing continuous curves using landmarks, the problem is treated analyt

Many studies focusing on design activities use the interview technique as part of their investigation. Nevertheless, methodological discussions about the interview setting as the locus of a social interaction between the interviewer and the respondent and its implications for the interpretation of the data obtained are rarely found in publications within our design community. Part I of this public

In this paper, we discuss the role of robustness to geometric conformity versus specificity in machine learning. The key observation made here is that object variation due to appearance and due to geometric deformation are often, for good reasons, intermixed in typical object detection applications. In the paper, we consider a whole range of differently specific object detectors. It is shown that

In this paper, we propose a novel multi-pitch estimator for stereophonic mixtures, allowing for pitch estimation on multi-channel audio even if the amplitude and delay panning parameters are unknown. The presented method does not require prior knowledge of the number of sources present in the mixture, nor on the number of harmonics in each source. The estimator is formulated using a sparse signal

In 2010 the Mozilla Foundation established the Digital Open Badges concept as a virtual incarnation of physical counterparts such as a paper certificate or a youth organisation merit badge. Digital Open Badges offer embedded, verifiable, metadata containing information such as the issuer and award criteria. Open Badges can be used to reward learning, participation or achievement. They can be store
