In editors for visual languages it is often useful to provide interactive feedback that depends on the static semantics of the edited program. In this paper we demonstrate how such feedback can be implemented using reference attribute grammars. Because the implementation is declarative, it is easy to modularize compiler and editor computations, reusing the compiler's program model in the editor. F

Short essay on Smommarnattens leende (1956)

Diode laser spectroscopy performed in the ultraviolet, visible and infrared spectral regions is presented. The accessible wavelength range for visible and near-infrared diode lasers is extended by the use of sum- and difference-frequency generation. Sum-frequency generation to the ultraviolet spectral region was employed using a blue and a red diode laser. Mercury spectroscopy was demonstrated wi

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

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

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.

Neutrino physics is one of the fastest growing topic in phenomenological high energy physics. Neutrinos are elementary neutral particles and participate only in the weak interactions. For this reason it is very difficult to detect them experimentally. Nevertheless, much experimental progress has been obtained in the recent years. In particular our knowledge of the neutrino masses and mixing angles

Ibland kan man som lärare undra om man lever som man lär. En sak är i alla fall säker, vi lär som vi lever! Vårt nya stressade levnadssätt påverkar givetvis vårt sätt att lära. Under en kort tidsrymd har tre tekniska produkter påverkat lärandet mer än vad läroplaner eller vetenskapliga pedagogiska genombrott någonsin gjort - datorn, internet och mobiltelefonen. Bodil myntar att vi idag lever på

Popular Abstract in Swedish Äldres vardagliga mobilitet är temat i denna avhandling. Den handlar dels om äldre personer i två bostadsområden i Malmö, dels om äldre personer som har blivit ensamma på äldre dar. Resultaten visar på olika sätt vikten av sociala nätverk och sociala relationer för att äldre personer ska kunna eller vilja ta sig ut om dagarna. Bostadsområdet för den första delstudien äThe overall aim of this thesis is to offer an understanding of everyday mobilities outdoors among older persons from a place- and context-dependent perspective. The emphasis is to take a gentle approach towards an overall perspective with consideration to physical aspects (like the home neighbourhood), social aspects (like social networks and social participation) and mental aspects (like place im

The paper presents the results from a course project which focused on all levels in ASIC design flow by implementing a complete MP3 decoder. Two student teams developed a decoder targeting ASIC and FPGA, respectively. The ASIC decoder, fabricated in a 0.35 μm process from AMI Semiconductor, consumes 40 mW with a supply voltage of 2 V running at 12 MHz. The FPGA decoder has been implemented and ver
