The long-run demand for money : a Wicksellian approach

The income velocity of money in several countries such as Sweden, the United States and Great Britain, displays a U-shaped pattern for the last one hundred years. This paper proposes an explanation of this secular behavior based on an extension of Wicksell’s work on velocity emphasizing the influence of institutional changes. The secular fall in velocity in the last half of the 19th century and th

Particle Filter for Combined Wheel-Slip and Vehicle-Motion Estimation

The vehicle-estimation problem is approached by fusing measurements from wheel encoders, an inertial measurement unit, and (optionally) a global positioning system in a Rao-Blackwellized particle filter. In total 14 states are estimated, including key variables in active safety systems, such as longitudinal velocity, roll angle, and wheel slip for all four wheels. The method only relies on kinemat

POET: A Portable Approach to Minimizing Energy Under Soft Real-time Constraints

Embedded real-time systems must meet timing constraints while minimizing energy consumption. To this end, many energy optimizations are introduced for specific platforms or specific applications. These solutions are not portable, however, and when the application or the platform change, these solutions must be redesigned. Portable techniques are hard to develop due to the varying tradeoffs experie

Frequent low-level mutations of Protein Kinase D2 in angiolipoma

Tumours displaying differentiation towards normal fat constitute the most common subgroup of soft tissue neoplasms. A series of such tumours was investigated by whole-exome sequencing followed by targeted ultra-deep sequencing. Eighty percent of angiolipomas, but not any other tumour type, displayed mutations in the protein kinase D2 (PRKD2) gene, typically in the part encoding the catalytic domai

Robotic Force Estimation using Dithering to Decrease the Low Velocity Friction Uncertainties

For using industrial robots in applications where the robot physically interacts with the environment, such as assembly, force control is usually needed. A force sensor may, however, be expensive and add mass to the system. An alternative is therefore to estimate the external force using the motor torques. This paper considers the problem of force estimation for the case when the robot is not movi

Thermal stability and structural changes in bacterial toxins responsible for food poisoning

The staphylococcal enterotoxins (SEs) are secreted by the bacteria Staphylococcus aureus and are the most common causative agent in staphylococcal food poisoning. The staphylococcal enterotoxin A (SEA) has been associated with large staphylococcal food poisoning outbreaks, but newer identified SEs, like staphylococcal enterotoxin H (SEH) has recently been shown to be present at similar levels as S
