Rate-distortion trellis source codes are developed for quantizing memoryless IID sources. The codes are generated by simple linear congruential recursions. The method generates codes at a variety of rates including fractional ones; reproducer sets can be large, a crucial advantage with certain sources. Axioms for good code construction are developed that are based on recursion properties, certain
We present a new technique for importance sampling products of complex functions using wavelets. First, we generalize previous work on wavelet products to higher dimensional spaces and show how this product can be sampled on-the-fly without the need of evaluating the full product. This makes it possible to sample products of high-dimensional functions even if the product of the two functions in it
Popular Abstract in Swedish Dokosahexaensyra (DHA) och eikosapentaensyra (EPA) är omega-3 fettsyror, som har hälsofrämjande effekter. De behöver skyddas, DHA i synnerhet, eftersom de är mycket känsliga för oxidation. Flera lipider som innehöll DHA utvärderades med avseende på lipidernas möjlighet att skydda DHA mot peroxidation genom att använda en HPLC metod som utvecklades som en del av detta arDocosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are omega-3 fatty acids, which have health promoting effects. Since they are highly prone to oxidation, they should be protected, in particular DHA. Several lipids containing DHA were evaluated with respect to the ability of the lipids to protect DHA against peroxidation using an HPLC method developed as part of this research. Furthermore,
This paper presents an evaluation of single input single output (SISO), single input multiple output (SIMO) and multiple input multiple output (MIMO) channel capacities for a dual antenna prototype in proximity of a user. The dual antenna prototype mimics today’s small mobile phone design in size and in comprising internal, compact, multi-band antennas. Four different user cases are evaluated by m
Popular science Glaciers are very sensitive indicators of climate change. The major cause of melting glaciers is global warming. This rapid rate of melting has serious negative impact on the earth causing flooding, leaving impact on flora and fauna, resulting in shortage of freshwater and hydroelectricity. The long-term monitoring of glaciers and the knowledge gained from it can help governments,
Att världen idag kan te sig ganska liten är inget att ta miste på. Det är betydligt lättare och kostar mindre att resa i förhållande till förr, vilket har bidragit till att många av oss i mycket större omfattning reser på semester eller i arbetet, och då stöter på - för oss - främmande och ibland komplicerade problem. Huvudregeln enligt svensk rätt är att bevis skall upptas vid förhandling, enliToday the world does not seem as large as we probably once thought. Many years ago traveling was difficult and quite expensive. Today it’s completely the opposite. All this convenience we experience has some consequences. During our travels and business endeavours with different parts of the world it is not surprising that we encounter problems. Since these problems are unfamiliar to us the proble
Scientific summary Satellite imagery has been used to produce highly accurate land cover maps, even effectively discriminating between vegetation types. While land cover classification based on differences in pixel values in one or more spectral bands is an effective way of mapping large areas, the coarse resolution of freely available satellite images is not suitable for mapping urban environment
Dealing with water diffuse pollution is a major problem for watershed managers. This problem raises many complicated questions, which are important to answer in order to reach water environment protection goals. This study suggested some possible answers for the country of Lithuania. Among them were the identification of critical source areas, the identification of sensitive areas and the applicat
The purpose of this paper is to analyse transient dynamics in adaptive control using statistical concentration bounds. For maximal clarity, the study is limited to a linear first order system with a single uncertain parameter. Two types of bounds are given: First we prove probabilistic bounds on the parameter estimation error as a function of time. In particular, we prove that the estimation error
With a perfectly uniform illumination, the amount and concentration of fluorophores in any (biological) sample can be read directly from fluorescence micrographs. However, non-uniform illumination in optical micrographs is a common, yet avoidable artefact, often caused by the setup of the microscope, or by inherent properties caused by the nature of the sample. In this paper, we demonstrate simple
In this paper, a proof of time-dependent behavior of heat flux into a cutting tool is built. Its implementation calls for a new method for estimating heat flux, which was developed using an inverse problem technique. A special experimental setup was designed and manufactured to implement the method. A series of dry machining experiments were conducted with high speed steel and cemented carbide too
Classification of EMG signals is essential for diagnosis of motor neuron diseases like neuropathy and myopathy. Although a number of strategies have been implemented for classification, none of them are efficient enough to be implemented in clinical environment. In the present study, we use ensemble approach of support vector machines for classification of three classes (normal, myopathic and neur
ECG is susceptible to parasitic myopulses due to the overlapping frequency bandwidth of ECG and EMG. EMG signal has a bandwidth of about 20-500 Hz and overlaps with the ECG frequency range. i.e. 0.05-150 Hz. These interferences occur due to movement of muscles and respiratory actions during ECG recording. Removal of EMG noise from ECG is an important criterion for proper analysis of the signal. In
Indolecarboxamidotetrazole compounds are well known as potential anti allergic agents due to their mast cell stabilizing activity on human basophils. A quantitative structure activity relationship (QSAR) model has been generated using Multiple Linear regression (MLR) for the prediction of inhibition efficiency of indolecarboxamidotetrazole derivatives. Twenty-one compounds with their activities ex
Equity refers to a fair sharing of costs or resources. Horizontal equity concerns distribution among individuals or groups with the same necessities, whereas vertical equity should be considered in situations with different levels of needs. This paper deals with transit service, looking at how to make it equitable from a spatial and social point of view. Traditionally equity has been neglected in
Abstract The organization of the health care system in Sweden has been subjected to investigations and discussions in order to make it more effective. The aim is to create a better public health care and to economize on the financial resources. In the year of 2003 an amendment of the Swedish law made it easier for municipalities and county councils to make own solutions and agree about how health
