Simultaneous laser-induced fluorescence (LIF) imaging of formaldehyde and a fuel-tracer have been performed in a direct-injection HCCI engine. A mix of N-heptane and iso-octane was used as fuel and Toluene as fluorescent tracer. The experimental setup involves two pulsed Nd:YAG lasers and two ICCD cameras. Frequency-quadrupled laser radiation at 266 nm from one of the Nd:YAG lasers was used for ex

The distribution of the output error burst lengths from a Viterbi decoder is of particular interest in connection with concatenated coding systems, where the inner code is convolutional. From the expurgated, random, and sphere-packing exponents for block codes an upper bound on this distribution for the ensemble of periodically time-varying convolutional codes is obtained. Finally, the distributio

The key success factor for companies is to develop and deliver services and products that satisfy customer needs and create customer value. When introducing e-businesses as a new channel, it is becoming increasingly important to consider customers, since they will have a higher level of influence on the company through the interactive channel. This paper sets out to describe the process of conside

In this paper, we study a flexible routing strategy for demand protection and a corresponding optimization problem for networks that permanently experience fluctuations of the capacity available on their links. This is an important and novel topic as limited link availability is a fundamental feature of wireless networks; yet majority of work in survivable network design is restricted to total fai

The purpose of this paper is to propose a conceptual model for analysis of marine incidents reported to the Swedish Maritime Administration (SMA)/ SOS database. The model is designed based on a systems approach. The model is theoretically and empirically grounded by combining (i) modelling, and accident and risk analysis techniques and theories; (ii) large amounts of empirical data; (iii) and rese

Prostate-specific antigen (PSA) and human prostatic glandular kallikrein (hK2) have 79% identity with the primary structure. When we used recombinant hK2 protein, only 7 of 23 monoclonal anti-PSA IgGs (monoclonal antibodies, MAbs) cross-reacted with hK2, which enabled us to design a novel immunofluorometric MAb-MAb assay for the specific detection of hK2. In the first incubation, an excess of MAb

Fusk och plagiat är något av en ödesfråga för den högre utbildningen. Om studenter klarar sig igenom kurser på grund av fusk hotas allmänhetens och arbetsgivarnas förtroende för den högre utbildningen. Tyvärr råder det idag en avsevärd oenighet om var gränsen för fusk går. Vi anser det därför vara hög tid att vi som lärare tar vårt ansvar och diskuterar dessa frågor ingående samt ger tips till var
