A highly integrated CMOS direct digital RF quadrature modulator, consisting of two 10-bit linear interpolation current steering digital-to-analog converters (DACs) and two Gilbert cell based mixers, is described. By employing linear interpolation, the attenuation of the DAC's image components is significantly increased, and the reconstruction filter is therefore eliminated. The DAC's differential

I started with a rather superficial overview of some of the problems that medieval archaeologists have to face when they try to study marginal areas, marginal in the view of those who are living near the political and economic power on one level or another. We can formulate the problems in centre-periphery models but we have also discussed some kind of world system thinking (which of course is con

This paper deals with geographical and organisational patterns of knowledge flows in the media industry of southern Sweden, an industry that is characterised by a strong ‘symbolic’ knowledge base. Aim is to address the question of the local versus the non-local as the prime arena for knowledge exchange, and to examine the organisational patterns of knowledge sourcing with specific attention paid t

We analyze atom-atom correlations in the s-wave scattering halo of two colliding condensates. By developing a simple perturbative approach, we obtain explicit analytic results for the collinear (CL) and back-to-back (BB) correlations corresponding to realistic density profiles of the colliding condensates with interactions. The results in the short-time limit are in agreement with the first-princi

In this work, we introduce a computationally efficient Kalman-filter based implementation of the robust widely linear (WL) minimum variance distortionless response (MVDR) beamformer. The beamformer is able to achieve the same performance as the recently derived robust WL MVDR beamformer, but avoids the computationally burdensome solution based on a second order cone programming (SOCP), and exploit

Popular Abstract in Swedish Bukspottkörteln (pankreas) består av en sekretorisk (exokrin) del, som producerar pankreassaft innehållande olika matspjälkningsenzymer vilka medverkar vid nedbrytningen av födan i tarmen, samt en hormoninsöndrande (endokrin) del, som producerar insulin och andra hormon vilka reglerar näringsomsättningen i kroppen. Vid en underproduktion av enzymer, exokrin pankreatisk Exocrine pancreatic insufficiency (EPI), resulting from disease (e.g. cystic fibrosis, chronic pancreatitis) or surgery (e.g. pancreectomy or pancreas duct ligation), leads to disorders in the digestive system, such as, maldigestion, malabsorption and finally malnutrition. Pancreatic duct-ligated (PDL) pigs have been used as a suitable large-animal model to study the conditions and treatment of EP

This paper provides an anthropological definition of "security" to discuss the nature of international intervention in the Balkans. Using examples from the author's development work in Albania, it describes how the international project implementation carried on by development NGOs interacts with local customary laws such as the Albanian 'kanun'. Projectization has created new project elites, but

The diffusion of digital technologies has strongly affected the way scholars and researchers use and perceive the archaeological information detected during the field investigation process. Archaeologists are still only beginning to realize the full potential of these applications beyond the attraction of providing visually engaging documentation and focus on the analytical and interpretive power.

In this report a generic model for the capture and assessment of end-user requirements and needs, the CREDIT carpenter model, has been developed. The main determinants of the model is the need for the project organisation (including the facilities management organisation) to ensure a thorough understanding of the end-user requirements and needs as well as an assessment through out the project proc

This is a summarizing commentary on ten chapters in the book.

Combining technology enabled learning and knowledge management is a very promising strategy to systematic competence building in software organizations. In order to set-up a combined learning and knowledge management environment and to support organization members in packaging small chunks of knowledge into courseware modules, Fraunhofer IESE developed the IntView-KM methodology. IntView-KM define

This paper explores the situation when tenants in public houses, in a specific neighborhood, are given the legislated right to buy the houses they live in but can choose to remain in their houses and pay the regulated rent. This type of legislation has been passed in many European countries in the last 30-35 years (U.K. Housing Act 1980 is a leading example). The main objective with this type of l

Most recent publications on spin-related phenomena focus on technological aspects of spin-dependent transport, with emphasis on the specific needs of spintronics. The present publication targets rather fundamental problems related to the physics of spin in solids, such as: manifestation of spin and orbital polarization in spectroscopy, including valence and X-ray photoemission, magneto-optics, low
