Extended Abstract. Small area estimation has received a lot of attention in recent years due to necessity demand for reliable small area statistics. Direct estimator may not provide adequate precision, because sample size in small areas is seldom large enough. Hence, by employing models that can use auxiliary information and area effects in descriptions, one can increase the precision of direct...

The history of weather radar is, among other applications, a manifestation of quantitative precipitation estimation (QPE), shown e.g. by Collier and Hardaker (2003). The main objective in such activities is to develop quantitatively accurate hydrological applications, especially nowcasting and warning systems of flash floods. The advantage of weather radars compared to conventional gauge networ...

Modern-day museums abound with ornate medieval and renaissance woven tapestries, which have been meticulously restored throughout the centuries. Although weaving can nowadays be described as a “dying art,” history tells a much different story about this trade and the abilities of 16 Century artisans. These masterful artisans could repair a woven textile such that the repair was virtually “invis...

Nowadays the free-access digital elevation models are getting more and more popular. The SRTM and ASTER GDEM databases are the most widespread. However, there are numerous situations and weaknesses we have to take into account during their usage, such as the direction-dependent accuracy and the difference between the digital and the real surfaces. Our goal was to examine these kinds of deficien...

Information needs associated with forest management and reporting requires data with a steadily increasing level of detail and temporal frequency. Remote sensing satellites commonly used for forest monitoring (eg, Landsat, SPOT) typically collect imagery with suffi cient temporal frequency, but lack the requisite spatial and categorical detail for some forest inventory information needs. Aerial...

The modern software defined radios (SDRs) use complex signal processing algorithms to realize efficient wireless communication schemes. Several such algorithms require a specific symbol to sample ratio to be maintained. In this context the fractional rate converter (FRC) becomes a crucial block in the receiver part of SDR. The paper presents an area optimized dynamic FRC block, for low power SD...

Earlier research has identified a remarkable number of related factors to resilience during adolescence. Historically, theoretical treatments of resilience have been focused almost exclusively on psychosocial levels of analysis to derive explanatory models. However, there is insufficient understanding of the role of emotion regulation explaining competent functioning despite the experience of a...

The present study was aimed to analyse the impact of biofield energy treatment on the physicochemical and spectral properties of 4-MBA. The compound was divided into two parts which are referred as the control and treated sample. The treated sample was subjected to Mr. Trivedi’s biofield energy treatment and analysed with respect to the control sample. The various analytical techniques used wer...

BACKGROUND Families with lower socioeconomic status (SES) often face problems with gaining access to health care services. Information is scarce on the relationship between SES and health care delivery for children suffering from chronic pain. METHODS Families presenting to a specialized pain center (N = 1,001) provided information on 'household income, 'parental education' and 'occupation' t...
