In this paper we investigate the mutual information in speech between the spectral envelope of the high frequency band and low frequency bands of various widths. Direct methods on the computation of the mutual information often result in an excessive amount of data required even for modest situations. We reduce the required amount of data by quantizing the low band leading to a lower bound express

Natural convective heat transfer along a vertical surface is of great importance in many different areas, such as cooling, energy systems, ventilation, room heating and fire safety. In this study, a large eddy simulation (LES) of natural convection along a vertical isothermal surface was carried out to analyze the natural convection boundary layer and the convective heat transfer. The results incl

The aim of this study was to explore employed women's experiences of light or moderate arm lymphoedema following breast cancer treatment in order to gain a deeper understanding of this phenomenon. Twelve women took part in a semistructured interview. A qualitative method with a phenomenological approach was applied to analyse data. in order to integrate the experiences in the everyday life of the

Chloride profiles were measured on ten different concrete qualities. The effect of two different cements, an ordinary Portland cement, OPC, and a sulfate-resistent Portland cement, SRPC, with and without inclusion of silica fume and fly ash was investigated. The samples were exposed to a 3 wt% sodium chloride solution for 119 days. Two different preparations before exposure were studied. Both type

The derivation of human embryonic stem (hES) cells establishes a new avenue to approach many issues in human biology and medicine for the first time. To meet the increased demand for characterized hES cell lines, we present the derivation and characterization of six hES cell lines. In addition to the previously described immunosurgery procedure, we were able to propagate the inner cell mass and es

Lack of courses in emergency medicine for doctors under training is currently a problem in Sweden. Only 10 percent will have these courses early under their internship. The University hospital in Malmoe has therefore decided to create a course for doctors under training and to offer it early in their education. The curriculum is based on a problem-based learning concept using a modified case metho

Let tau(n) be the first time a queueing process like the queue length or workload exceeds a level n. For the M/M/1 queue length process, the mean Etaun and the Laplace transform Ee(-staun) is derived in closed form using a martingale introduced in Kella and Whitt (1992). For workload processes and more general systems like MAP/PH/1, we use a Markov additive extension given in Asmussen and Kella (2

Flow cytometric (FCM) DNA analysis yields information on ploidy status and the S-phase fraction (SPF), variables of prognostic importance in breast cancer. The clinical value of the SPF is currently being evaluated in prospective randomized trials. The widespread use of FCM DNA analysis emphasizes the importance of reproducibility (both intra- and interlaboratory). In this study, 67 nuclear suspen

This study presents flow and heat transfer predictions of multiple slot air jets impinging on circular cylinders using CFD (computational fluid dynamics). The distribution of Nusselt numbers around the cylinders for different Reynolds numbers (23,000-100,000), distances between the jets, and openings between them was determined for two and three jets and compared to simulations of a single jet. Th

A prospective study was carried out in 499 patients admitted to a coronary care unit (CCU) in order to evaluate the incidence of clinically significant electrolyte disturbances. Low serum potassium values (less than 3.6 mmol l) occurred in 7% of the CCU patients and low serum magnesium values (less than 0.70 mmol l-1) in 6%. Few patients had low values of both these ions (1.9%). In 49 patients the

In all societies, personal names are important as a means for recognizing and distinguishing people. The paper, following Claude Lévi-Strauss’ theories on how people systematize the surrounding world through named categories, focuses on how we use names to gain knowledge about who a person “is”. We base our conclusions on culturally shared knowledge about how specific names are related to gender,

With the increasing, use of short-range wireless devices for high-data-rate communication in the shared frequency bands, the level of interference can be expected to increase. The ability to,estimate, the performance degradation of these devices due to increasing interference is, therefore, important. In this paper, the throughput of devices that perform frequency hops after each transmitted packe

Bilateral foreign aid negotiations between industrialized and less developed countries; based on conference paper. Characteristic features of foreign aid negotiations, as compared to other types of negotiations between states; influence of factors which are external in relation to the negotiations themselves.

A soft x- ray laser from Ni- like Mo, pumped in grazing incidence ( GRIP), is analyzed with regard to high repetition rate operation. Reliable lasing is obtained, but with significant energy fluctuations attributed mainly to beam pointing jitter from the pump laser. Two modes of operation are compared: continuously moving target and stationary target. With a moving target the soft X- ray output is

To investigate whether biotransport constitutes an entry route into pristine ecosystems for nonpersistent, nonvolatile xenobiotic compounds, extractable organically bound halogen in sockeye salmon (Oncorhynchus nerka) from Alaska was determined before and after spawning migration. The major organohalogen compounds in the salmon were halogenated fatty acids, predominantly chlorinated species that a
