A feedback-based scheme for cooperative content distribu- tion for mobile systems aimed at reducing energy and li- censed spectrum usage is presented. The paper is motivated by the problems in implementing peer-to-peer based content distribution in mobile networks due to the risks of unfair en- ergy expenditure. A technique for incentivizing cooperation and for enforcing agreements between peers i

This paper presents a methodology to reduce the power consumption, by using multiple supply voltage levels. The voltage levels are scaled down from a single supply voltage, by the use of a diode-connected device. Only one single device is used per conversion, which gives a small area overhead. No inductors and no off-chip components are used. The methodology is tested on different constellations o

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 two improvements to a recently proposed framework based on global optimization. The mesh geometry is analyzed both from a theoretical and experimental viewpoint and hexagonal meshes are shown to be superior. Our se

Business Rules (BR) and Business Processes (BP) are essential pillars in any Business Information System (BIS) and important areas of BIS design (BISD). Historically, BRs have been overlooked as a part of BISD. The Business Rules Approach (BRA) focuses on concepts and methods to remedy the neglected BR design and management. BRs in this perspective are stateless and concerned with the “what” of a

The required moment of inertia for steel plate girders is commonly provided by using relatively slender webs to achieve high strength-to-weight ratio. A large part of the shear capacity of such plate girders depends on the post-buckling reserve strength of the web panels due to the diagonal tension field mechanism. The effectiveness of the tension field significantly depends on geometrical and mec

Robotised welding is one of the most important robot tasks used in manufacturing industry. The operator usually performs the programming of the robot manually, i.e. by jogging the robot arm to each coordinate pose in space. Programming can, however, be made more accurate by the use of simulation, using so called Computer Aided Robotics. Simulation can also be a powerful tool to evaluate and contro

We present a method for studying large finite periodic structures using soft- ware developed for infinite periodic structures. The method is based on the Floquet-Bloch transformation, which splits the spatial description into one microscopic spatial variable inside the unit cell, and one macroscopic wave vector describing the variations on a scale encompassing many unit cells. The resulting algori
