Lattice Boltzmann method (LBM) is an alternative to conventional CFD to capture the detailed activities of the transport processes at microscale. Here LBM is used to model the hydrogen production by splitting water by incident sunlight over water covered Si-nanorods. The purpose of this study is, by a 3D microscale model, to investigate the transport and the formation of the hydrogen bubbles by el

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
