Despite rapid development, modern graphics hardware is still much too slow to render photo-realistic images in real time, and it will most likely remain so if we rely only on yearly growth in hardware performance. Therefore, better algorithms are constantly needed in order to advance the field. In the first part of this thesis, we present new algorithms for hardware rasterization. We investigate
Popular Abstract in Swedish Denna avhandling beskriver olika optiska metoder för att diagnostisera cancer.En sådan metod är optisk spektroskopi (att med hjälp av ljus bestämma fysiska och kemiska egenskaper hos ett prov) som har används för att undersöka cancer i ögat. Avhandlingen omfattar vidare studier av optiska kontrastmedel tillverkade av nanokristaller (nano = en miljarddels meter), vilkas This work presents optical methods for diagnosing cancer. A complementary method for diagnosing eye cancer was investigated using a technique developed within this work named transscleral optical spectroscopy (TOS). Furthermore, nano-sized crystals doped with lanthanides were exploited as probes for fluorescence imaging with direct applications to preclinical cancer research. Almost all intraocul
We present a multiuser synchronization scheme for tracking the mobile's uplink time and frequency offsets. It uses the redundancy introduced by the cyclic prefix and does not need additional pilots. We show performance results of an orthogonal frequency division multiplexing (OFDM)-based radio interface based on the universal mobile telecommunication system (UMTS) parameters. For a UMTS-typical mo
Magnetic resonance spectroscopy (MRS) is a non-invasive technique that can be used to detect and quantify multiple metabolites. This chapter will review some of the applications of MRS to the study of brain functions. Typically, (1)H-MRS can detect metabolites reflecting neuronal density and integrity, markers of energy metabolism or inflammation, as well as neurotransmitters. The complexity of th
In this study, the upward (IUS) and downward (IDS) slopes of the QRS complex are proposed as indices for quantifying ischemia-induced electrocardiogram (ECG) changes. Using ECG recordings acquired before and during percutaneous transluminal coronary angioplasty (PTCA), it is found that the QRS slopes are considerably less steep during artery occlusion, in particular for IDS. With respect to ischem
Popular Abstract in Swedish Trådlös kommunikation via radiosystem har närapå blivit en rättighet i dagens samhälle. Vi förväntar oss att internet inte ska vara mer fjärran än där vi senast lade vår ``smarta mobiltelefon''; antagligen inom armlängds avstånd. Strömmning av data ökar ständigt då vi nuförtiden själva vill bestämma när och var vi ska avnjuta, till exempel senaste säsongen i favoritseRadio systems, along with the ever increasing processing power provided by computer technology, have altered many aspects of our society over the last century. Various gadgets and integrated electronics are found everywhere nowadays; many of these were science-fiction only a few decades ago. Most apparent is perhaps your ``smart phone'', possibly kept within arm's reach wherever you go, that prov
Large carnivore conservation in the Swedish multi-use landscapes can only be successful if carnivores can share the landscape with human activities. Interventions to reduce the risk of brown bear, lynx, wolf, and wolverine attacks on domestic animals have become a core element in carnivore management. Whereas the intention is that interventions mitigate human-carnivore interactions, the interventi
In April of 2004, about a year after the start of the Iraq War, a story broke in the American media about the abuse of Iraqi detainees by American soldiers at the Abu Ghraib prison outside Baghdad.1 From the beginning, editorialists and science writers noted affinities between what happened at Abu Ghraib and Philip Zimbardo’s 1971 Stanford Prison Experiment.2 Zimbardo’s experiment is part of a bod

Randomized clinical trials are the preferred study design to address key research questions about the benefits or harms of interventions. However, randomized trials of oxygen therapy are difficult to conduct and have limitations. The purpose of this article is to offer our view on the potential use of patient registries in the field of home oxygen in COPD as an alternative to randomized trials by
Certain retinal diseases that result in partial or complete visual loss due to the death of photoreceptor cells. These diseases can affect all ages, accounting for a significant fraction of blindness among younger adults in the developed world. Currently, no effective cure for these diseases exists. As they kill photoreceptors but leave the remaining retina and visual pathways comparatively intact
Program parallelization and distribution becomes increasingly important when new multi-core architectures and cheaper cluster technology provide ways to improve performance. Using declarative languages, such as constraint programming, can make the transition to parallelism easier for the programmer. In this paper, we address parallel and distributed search in constraint programming (CP) by proposi
