Different methods to separate quark jets from gluon jets have been investigated and tested on data from the DELPHI experiment. A test sample of gluon jets was selected from $bar{b}g$ threejet events where the two b-jets had been identified using a lifetime tag and a quark jet sample was obtained from $qar{q}gamma$ events where the photon was required to have a high energy and to be well separated
Under the Leonardo da Vinci – Lifelong Learning Programme (LLP) – there is a sub-programme, Transfer of Innovation (ToI). ToI is funding projects which further develop previous project outcomes. This paper deals with a new pilot project under ToI, eGIS+, which has received funding for two years (2007 – 2009). eGIS+ further develop a previous pilot project, E-GIS (European Level Developments of Fle
The Nordic countries have often been seen as “fore-runners” of energy efficiency in buildings in terms of both 1) the implementation of policy instruments and 2) the evaluation of actual effects. Since the 1970s, the Nordic countries have introduced a range of policy instruments for energy conservation in buildings. Interestingly, there are contrasting policy “styles” and experiences across the No
This work focuses on measurement principles based on ultrasound for applications in industrial automation. The measurements made are of geometric nature. The methods used are when possible based on experience and/or inspiration from the study of bats. A platform for ultrasonic measurements, that allows a VME-based host computer to transmit and receive signals, with a considerable flexibility has b
The simulation approach is an important tool used for the design and implementation of mobile radio systems with an emphasis on the propagation modeling for wireless channel. We carried out simulations for three different street positions scenarios of the receiver, (mobile station), using the geometrical-based single bounce elliptical channel model, as might be appropriate for microcellular applic
The strong process forces arising during high-speed machining operations, combined with the limited stiffness of industrial robots, have hampered the usage of industrial robots in high-end milling tasks. However, since such manipulators may offer flexible and cost-effective machining solutions, a three-dimensional piezo-actuated compensation mechanism, which aims to compensate for the positioning
Popular Abstract in Swedish Omkring hälften av alla kvinnor kommer någon gång efter 50 års ålder att drabbas av ett benbrott. Ett benbrott ger upphov till smärta, en risk för långvarig invaliditet och förtida död. Det är viktigt att försöka hitta dem som riskerar att drabbas, eftersom det möjliggör förebyggande behandling. Hur stor risken är att man drabbas av ett benbrott på äldre dagar beror fraApproximately half of all women will sustain a fracture after the age of 50. Fractures may cause long-term disability and excess mortality. Identifying individuals at high risk of sustaining a fracture is important in the development of primary and secondary prevention strategies. In this study, initiated to identify factors associated with a high risk of future fractures, 1 044 women, all 75 yea
In Western classical music traditions, conventional ways of considering melody have been established. The tones of a melody phrase might be experienced as building up a continuous line moving between dynamical culmination points and relaxation points. In this study, a special visual tool called the Melody phrasing curve (MPhC) has been tested. The MPhC is designed according to some established con
Long-term instability in multiplanet exosystems is a crucial consideration when confirming putative candidates, analysing exoplanet populations, constraining the age of exosystems and identifying the sources of white dwarf pollution. Two planets that are Hill stable are separated by a wide-enough distance to ensure that they will never collide. However, Hill-stable planetary systems may eventually
The food system accounts for a significant portion of environmental degradation, while it is at the same time to a large extent producing food that is deteriorating to human health. The private sector plays an essential role in contributing to the sustainability of the system. Based on a systematic literature review, we conceptualise the notion of sustainable nutrition (SN), which highlights the i
Aim: Phantoms are used daily in the clinic for radiotherapy. As more realistic phantoms are requested, 3D printing could be used but the design of a realistic phantom is difficult. The purpose of this project was to design and 3D print an anthropomorphic phantom that could be used for verification of complex treatment such as stereotactic arrhythmic radioablation treatments without the use of pati
Background - The company is a Swedish manufacturer, developer and contract manufacturer of pharmaceuticals. In the last couple of years, the company has entered a growth phase which has led to issues with the internal processes such as material flow, warehouse operations and processes related to the production. The consequence has been occasional issues with delivering the products on time. As a r
Policy Coherence for Development is a concept, framework and tool for achieving a more effective and organized global development agenda. Under the principles of Policy Coherence for Development (PCD), the potential conflicts of objectives between various policy areas should be identified and preferably resolved – with developmental objectives in mind. The PCD has named some policy areas as “expec
