Vectoring is a vital component of wideband wire- line communication systems. A disorderly leaving event (DLE) disturbs the vectoring operation since the precoder, which was designed for the channel before the change, is no longer up to date. Measurements indicate that the impact of a DLE can be serious for frequencies beyond 30 MHz, which corresponds to the band used by emerging wideband communica
The St Louis aerosol was sampled during the period 16-22 August 1973 simultaneously at two locations using cascade impactors for sequential 12-hour samples. The six particle size fractions of each sampling were individually analyzed using PIXE for elements from S to Br and beyond and for heavy elements including Pb which permitted time variations of concentrations and particle size distributions t
The heat conduction in a two-dimensional square plate at nano/micro scales is investigated using numerical and semi-analytical methodologies which are energy conserving dissipative particle dynamics (DPDe) and Boltzmann transport equation (BTE) with the gray relaxation time approximation. The solution domain was considered to be a two-dimensional square plate surrounded by walls having constant te
Popular Abstract in Swedish Blodtrycket bestäms av hjärtats minutvolym och det perifera kärlmotståndet. Det perifera kärlmotståndet regleras med hjälp av substanser som verkar lokalt på kärlväggen. Dessa substanser kan frisättas från nerver vid nervaktivering. De kan också vara hormoner eller andra kärlaktiva ämnen, även sådana som tillförts exogent, till exempel anestesimedel. Endotelet, som utklRegulation of blood flow involves several endogenous substances and mechanisms, and exogenous substances may also affect the blood flow. In the present thesis, human omental blood vessels were investigated in vitro concerning (i) characteristics of 5-hydroxytryptamine (5-HT) receptors; (ii) mediators of substance P (SP)-induced relaxation; (iii) direct and indirect (via effects on sympathetic neur
Byggkostnader och boendekostnader är välkända exempel på ord som ofta ”blandas ihop”. I ” Begrepp i bygg- och fastighetssektorn” definieras och förklaras dessa och andra vanligt förekommande begrepp i bygg- och fastighetsutvecklingsprocessen. Tanken med boken är att bidra till en enklare och tydligare kommunikation i byggprocessen. Alla ord redovisas i alfabetisk ordning med förklaringar och komme
A soft output decoding algorithm for convolutional codes, yielding list sequence (LS) decoding and soft symbol output was presented. The max-log list algorithm (MLLA) was introduced, it provides near-optimum soft symbol output equal to that of the max-log MAP algorithm. It was shown that the suboptimum MLLA provides the performance-complexity tradeoff.
This paper compares two hardware design flows, based on the classic VHDL on one side and the relatively new Bluespec System Verilog (BSV) on the other side. The comparison is based on a case study of a Java embedded architecture, comprising a Java native processor and a memory management unit. The processor is a micro-programmed, pipelined, Java-optimized processor (JOP), initially written in VHDL
The first chapter of this paper will give an overview of different ways of developing a university’s teaching and learning. There are many single activities that individually deal with the topic in a positive direction, such as teacher training, develop learning environments, develop teacher reward systems, etc. Traditionally educational development has been about these single activities focusing
Background: Postnatal sense of security, for parents, the first week after childbirth is important for their own and their baby’s wellbeing. Variables influencing the mother’s, and particularly the father’s, sense of security during the first postnatal week are not well known. No instrument measuring dimensions which can be influenced and supported by the postnatal health care team has been found
