We present a low-delay vector predictive transform coder with quantization noise modeling. The coder uses overlapped transform coding and a Kalman filter with a backward estimated LPC model of the speech signal combined with an additive noise model of the quantization noise. The noise model is driven by the vector quantizer. Each quantizer cell has its own error correlation matrix, which is kept i

Computer-based design analysis is nowadays a common activity in most development projects. Used for design evaluation, verification, validation, or as a support for design exploration, it fulfils an important support function for the engineering designer, thus making it essential to have an operationally efficient and effective integration between both the engineering design and design analysis ac

The new contacts with the west reaffirmed the idea of interaction between the west and the Arab world. New literary works compared and contrasted the spirituality of the East with the materialism of the West - a theme that became a common one in modern Arabic literature.

In the article the spatial organisation of everyday life at two deserted medieval farmsteads/hamlets, and the practise of outland use in their surrounding landscapes are discussed from a gender perspective. A gender hierarchy, with male domination, is clearly visible in the matierals.

The word “desertification” was introduced in 1949 by the French scientist Aubreville in his report “Climats, forêts et désertification de l´Afrique tropicale”. The concept, however, was discussed earlier by European and American scientists in terms of increased sand movements, desiccation, desert and Sahara encroachment and man made deserts. Desertification, at the beginning of last century, mea

BACKGROUND: Recently, a -168A-->G polymorphism in the MHC class II transactivator gene (MHC2TA) was shown to be associated with increased susceptibility to myocardial infarction (MI). AIM: To confirm the association between the MHC2TA -168A-->G polymorphism and MI and to study its putative role for microalbuminuria, the metabolic syndrome (MetS) and cardiovascular mortality. MATERIALS AND METHODS:

Quasi-experimental study of effects of an organizational intervention on staff and patients over a 8 year perspective; Before, under and after an organizational change. Effects on staff are staff-turnover, fatigue and burnout (n=268) on Three wards including the intervention ward. Independent variables are staff demographics, education, experience, job status, sick-leave and responses on a burn-ou

This study is based mainly on observations and interviews accomplished on two occasions with nursing assistants employed at two group living units for older people suffering from dementia in Sweden. The interviews and observations were carried out one year apart, before and after a project that also included supervision of managers and nursing assistants. I interviewed 12 nursing assistants, 8 of

The purpose of this dissertation was to study how to interpret ecstatic spirituality, illustrated by the Toronto Blessing, from a religio-psycho¬logical point of view. The study is a qualitative research based on inter¬views, field observations and written documents. The theo¬retical framework is interdisciplinary, using theories from ego-psychology, social psychology, sociology, cultural anthropo

The subject of this study is the re-intensified dispute between rhetoric and philosophy in the times of the Second Sophistic. The focus of our investigation has been on two authors of this period who have left behind treatises the explicit purpose of which is to attack or defend rhetoric: Sextus Empiricus who is sharply criticising rhetoric and Aelius Aristides who is defending it. Our purpose has

Huntington's disease (HD) is a fatal genetic neurodegenerative disorder caused by a CAG triplet repeat expansion in the gene encoding the protein huntingtin. The most studied model of HD, the R6/2 transgenic mouse, replicates many features of the disease. In addition to motor, cognitive, and endocrine dysfunctions, these mice exhibit a progressive disruption of circadian rhythms. This is accompani

A mathematical model has been developed based on the fundamental properties of the control system formed by the lux genes and their products in Vibrio fischeri. The model Clearly demonstrates how the components of this system work together to create two, stable metabolic states corresponding to the expression of the luminescent and non-luminescent phenotypes. It is demonstrated how the cell can "s

Alzheimer’s disease (AD) is an age-related, irreversible brain disorder that occurs gradually and results in memory loss, behavioural and personality changes. The disease is characterized by an abnormal accumulation of amyloid-beta (Ab) peptide in the extracellular space and the protein Tau within nerve cells of certain regions of the brain. Aâ1-42 is a major component of amyloid deposits in AD, b
