Panel Presentation on ethnographic approaches to U.S. Aid, using the concept of "Aidland" as a place one studies and the ideas of Marcel Mauss looking at donors as giftgivers, explicating the discourse of "partnership" when the donors and recipients are unequal. Based on the author's work as democracy consultant in Kosovo, Albania, Bosnia, Romania.

High resolution radio based positioning and tracking is a key enabler for new or improved cellular services. In this work, we are aiming to track user movements with accuracy down to centimeters using standard cellular bandwidths of 20-40 MHz. The goal is achieved by using phase information from the multi-path components (MPCs) of the radio channels. First, an extended Kalman filter (EKF) is used

The ecological and genetic effects of habitat fragmentation are an issue of major concern in current conservation biology. Habitat fragmentation results in smaller habitat areas and as a consequence smaller and more isolated populations. Many habitats have become fragmented through human activities such as forestry and agricultural development. In Sweden, for example, the area of species-rich, sem

This paper presents a resource management strategy for control tasks that maximizes control performance within the available resources by readjusting the task periods at run-time. A feedback scheduler is used to determine on-line the optimal task periods considering the response over a finite time horizon of the plants controlled by arbitrary linear control laws. We show how this problem can be ex

Ambitionen att förhindra uppkomsten av kriser innebär att EU slagit in på en farlig väg där olika demokratiformer växlas mot varandra. EU:s krav på könsbalanserade styrelser är ett exempel, skriver Lars Oxelheim.

A predictive PI (proportional-integral) controller with dead-time compensation is described. Its advantage compared with previous dead-time compensating controllers is that although it also contains five parameters, only three are adjusted by the operator, namely, the gain, the integral time and the dead time. The controller is also suited for processes with varying dead times. Conceptually, the n

Popular Abstract in Swedish Experimentella data från kollisioner mellan guldjoner vid hög energi har analyserat inom ramen för experimentet PHENIX, som finns vid en av kollisionspunkterna vid ''the Relativistic Heavy-Ion Collider'' på ''Brookhaven National Laboratory'', New York (USA). Kollisioner med tunga joner, så som guld, används i försök till att återskapa de förhållanden som fanns i univerThe properties of the basic building blocks of nuclear matter, the quarks, and their interactions are not known in detail, largely because observations are complicated by the confinement of quarks in composite particles. New insights can be gained from the study of nuclear matter in a deconfined phase, like the form of matter that the Universe consited of early in its evolution according to the Bi

Metamaterial applications such as cloaking, perfect lenses, and artificial permeability are restricted by the frequency dependence of the permittivity, permeability, and index of refraction. Here, causality and passivity together with integral identities for Herglotz functions are used to construct sum rules. The sum rules relate the frequency dependence of the material parameters with their high-
