“The important criterion for a graph is not simply how fast we can see a result; rather it is whether through the use of the graph we can see something that would have been harder to see otherwise or that could not have been seen at all.” William S. Cleveland When presenting graphs for people with visual impairments the solutions found on the market today often present pure data values only. Over
That data from polar orbiting satellites have detected a widespread increase in photosynthetic activity over the last 20 years in the grasslands of the Sahel is justifies investigating its role in the tropical carbon cycle. But this task is undermined because ground data that are generally used to support the use of primary production models elsewhere are lacking. In this paper, we profile a Light
This thesis is based on six scientific papers providing different methods for coordinated inventory control in supply chains. The main focus is on supply chains in connection with distribution of products to customers. Two different problem areas are considered. One problem area concerns coordination by centralized optimization of local decision rules. It is assumed that the decision system is ce
Despite modern advances in the treatment of head and neck cancer, the survival rate fails to improve. Considering the different treatment modalities involved, quality of life has been thought of as an additional end point criterion for use in clinical trials. A Nordic protocol to measure the quality of life of head and neck cancer patients before, during, and after treatment was established. Befor
Popular Abstract in Swedish Avhandlingen beskriver och diskuterar de tidskrifter och böcker som muslimer i Sverige skrivit på svenska under 1900-talet. Framförallt gås innehållet i tidskriften Salaam - Islamisk Tidskrift (grundad 1986) igenom. Innehållet diskuteras i förhållande till hur islam har globaliserats de senaste tre decennierna. En slutsats är att Salaams skribenter har försökt att knyta
Popular Abstract in Swedish Parkinsons sjukdom uppstår när celler som producerar signalsubstansen dopamin i hjärnan dör. Detta leder till att de drabbade patienterna blir stela, får långsamma rörelser, svårt att påbörja och avsluta rörelser och även skakningar i framförallt armar och händer. Idag finns inget sätt att bota sjukdomen. Dock finns det läkemedel som kan lindra symptomen. Den vanligasteThe main pathological feature in Parkinson's disease is the progressive loss of dopamine neurons in the midbrain, which in turn leads to the appearance of motor deficits such as akinesia/bradykinesia (loss/slowness of movements), rigidity, postural imbalance and tremor. To this day, there is no cure for the disease, but there are medications to relieve the symptoms. The gold standard medication is
An isochromosome of the long arm of chromosome 17, i(17q), is the most frequent genetic abnormality observed during the disease progression of Philadelphia chromosome-positive chronic myeloid leukemia (CML), and has been described as the sole anomaly in various other hematologic malignancies. The i(17q) hence plays a presumably important pathogenetic role both in leukemia development and progressi
Volatiles are efficient mediators of chemical communication acting universally as attractant, repellent or warning signal in all kingdoms of life. Beside this broad impact volatiles have in nature, scents are also widely used in pharmaceutical, food and cosmetic industries, so the identification of new scents is of great industrial interest. Despite this importance as well as the vast number and d
A simple labeling approach is presented based on protein expression in [1-C-13]- or [2-C-13]-glucose containing media that produces molecules enriched at methyl carbon positions or backbone C-alpha sites, respectively. All of the methyl groups, with the exception of Thr and Ile(delta 1) are produced with isolated C-13 spins (i.e., no C-13-C-13 one bond couplings), facilitating studies of dynamics
Popular Abstract in Swedish Neuroblastom är den vanligaste solida tumören, utanför hjärnan, hos små barn och finns nästan inte alls hos vuxna. Varje år insjuknar mellan femton och tjugo barn i Sverige, de flesta före två års ålder. Överlevnaden har ökat de senaste tjugo åren men är fortfarande på låga nivåer för de mer aggressiva formerna. Neuroblastom uppstår i det sympatiska nervsystemet. DärförIn this thesis, the main focus has been on the childhood cancer neuroblastoma, one of the most common and lethal childhood tumours. Neuroblastoma has througout the years continued to be a clinical and biological enigma. Our first focus was on one of the most important biological risk factors in neuroblastoma -- amplification of the oncogene MYCN in the tumour cells. Because amplified MYCN typical
Objective. The popliteal artery is, after the aorta, the most common site for aneurysm formation. Why the popliteal artery is more susceptible than other peripheral muscular arteries is unknown. An important factor may be differences in arterial wall composition as compared with other peripheral muscular arteries, which in turn affect wall properties. These are however unknown. We studied the mech
The thesis concerns the development and application of two laser-based methods for combustion diagnostics: dual broadband rotational coherent anti-Stokes Raman spectroscopy (CARS) and laser-induced fluorescence (LIF). In efforts to increase the usefulness of the CARS technique, the applicability of a method involving a combination of the rotational CARS technique and the closely related vibration
Summary form only given. In this paper, we examine the effect of block size on the performance of trellis based quantization. In particular, the Viterbi and tailbiting BCJR algorithms are compared. It is shown that for short blocks of data, the T-BCJR algorithm achieves a superior performance over the Viterbi algorithm (VA). One approach is to use the maximum a posteriori probability (MAP) heurist
The number of applications in computer vision that model higher-order interactions has exploded over the last few years. The standard technique for solving such problems is to reduce the higher-order objective function to a quadratic pseudo-boolean function, and then use roof duality for obtaining a lower bound. Roof duality works by constructing the tightest possible lower-bounding submodular fun
We consider propagation models that describe the spreading of an attribute, called “damage,” through the nodes of a random network. In some systems, the average fraction of nodes that remain undamaged vanishes in the large system limit, a phenomenon we refer to as exhaustive percolation. We derive scaling law exponents and exact results for the distribution of the number of undamaged nodes, valid
Multiphase clock generators are conventionally implemented with a feedback loop. This paper presents a non-feedback approach to generate multiphase clocks. A simple architecture of direct phase interpolation is proposed, in which the edges of two phase-adjacent signals are used to control the discharge (or charge) of two capacitors respectively, producing time-overlapped slopes. A resistor chain c
Mesh networking is currently gaining much attention, within both academia and industry. Mesh networking allows cheap and fast deployment of wireless services. It is regarded as a very promising solution for urban deployment scenarios as well as for temporary emergency response situations. Another related promising field is that of ad hoc wireless networking, which consists of mobile nodes that dyn
Packaging Logistics is a concept that recognises the need for coordination of the packaging system and its manifold functions throughout a package’s life cycle. Packaging Logistics is an area in need for substantial theoretical building. This dissertation elaborates on its underpinnings and suggests conceptual models that should be useful in better understanding the core of the concept, its undere
