Auto-ignition with SI-compression ratio can be achieved by replacing some of the fresh charge by hot residuals. In this work an engine is run with a negative valve overlap (NVO) trapping hot residuals. By increasing the NVO, thus raising the initial charge temperature it is possible to investigate the intermediate zone between SI and HCCI as the amount of residuals is increased. Recent research ha

An algorithm for decoding turbo codes that combines conventional turbo decoding and list sequence (LS) maximum a posteriori probability (MAP) decoding is presented and evaluated. Compared to previous results on this theme, a reduction in the order of 0.7 dB of the signal-to-noise ratio (SNR) is obtained for turbo codes with 514-bit pseudo-random interleaving at frame error rate (FER) 10^-4

Popular Abstract in Swedish En ny bildgivande detektor för realtids registreringar av laddade partiklar (beta-partiklar, konversions-elektroner och alfa-partiklar) från tunna preparat har utvecklats, Betakamera. Den består av en ljuskänslig detektor, baserad på mikrokanalplattor, en fotokatod och en resistiv anod . Preparatet som ska registreras placeras mot en plastscintillator, vilken är monteraA new detector for on-line digital detection of charged particles (beta-particles, conversion electrons and alpha-particles) from thin samples for rapid autoradiography has been developed; the Beta Camera. The device consists of a photon-sensitive detector (image photon detector, IPD); the main component of which is a microchannel plate. The sample to be measured is mounted in close contact to a t

This report presents a project at Lund University Libraries (LUB) during the fall of 2012, with the object to identify areas where the present research support services ought to be developed and strengthened. The project is three folded and contains a) a literature review focusing on definitions and examples of research support services as well as researchers’ needs and experiences of support serv

As climate models can be used to reproduce historical climates, the outcomes can be used to put climate extremes in to a proper historical perspective. This also allows investigation of nonlinear properties of hydrologic processes (e. g. precipitation, runoff) to better understand regional hydrologic dynamics. To this end, the present study uses results from a so-called 'paleosimulation' (i.e. sim

Theoretical calculations concerning the advanced understanding of atomic structure and transitions has been performed for some atomic systems. The importance of different types of correlation depending on system has been investigated both using relativistic and non-relativistic quantum mechanics. Methods for simplifying the analysis of special types of spectra is presented and transition rates and
