The development of MIMO over-the-air (OTA) test methodology is an ongoing activity in 3GPP RAN4, CTIA and EU COST Action 2100. In this paper, the focus is on the anechoic chamber approach, which uses a uniform circular array of probe antennas to replicate directional channels for the device under test (DUT) at the array center. In particular, we study in simulation the complexity requirements of i

This thesis focuses on the validation and description of the Gumbel distribution. Since this is a scale and location parameter distribution, the generalized least squares regression of the order statistics on the expected values can be used, without the necessity of iteration, to obtain the best linear unbiased estimates of the parameters. In order to implement this procedure, we need informatio

The control of inventories is a key issue for achieving efficient management of supply chains. This Licentiate Thesis is devoted to inventory control theory, a subdiscipline within the field of operations research and the management sciences. The objective of the research presented is: To develop mathematical models for efficient control of stochastic multi-echelon inventory distribution systems,

This paper studies the issue of whether money contains useful information about future inflation in a panel of nine developed countries. A low frequency estimate of excess money growth is compared to an estimate of the inflation trend following the discussion in Woodford (2007). The empirical analysis shows that money contains more information about future CPI-inflation than an estimate of the inf

Mechanical function of articular cartilage in joints between articulating bones is dependent on the composition and structure of the tissue. The mechanical properties of articular cartilage are traditionally tested in compression using one of the three loading geometries, i.e., confined compression, unconfined compression or indentation. The aim of this study was to utilize a composition-based fin

A PtdIns 4-kinase was purified extensively from rat liver exocytotic vesicles. The enzyme had a low Km for ATP, was inhibited by adenosine, and had an apparent molecular mass of 54 kDa, indicating it to be a type II PtdIns-kinase. The activity of the purified enzyme was enhanced several-fold by PtdCho, and to some extent by other phospholipids with basic polar head groups, and was inhibited by Ptd

LCG and ARC are two of the major production-ready Grid middleware solutions being used by hundreds of HEP researchers every day. Even though the middlewares are based on same technology, there are substantial architectural and implementational divergencies. An ordinary user faces difficulties trying to cross the boundaries of the two systems: ARC clients so far have not been capable accessing LCG
