  2. 1. On the efficiency of displacement ventilation

    Author : Magnus Mattsson; KTH; []
    Keywords : ;

    Abstract : The efficiency of room ventilation by the displacementprinciple was studied with respect to some influential factors,in particular that of physical activity. The study wasexperimental and performed in two full-scale test rooms, one ofoffice-size and one of classroom-size. READ MORE

  5. 3. Offset Management for Large Systems : A Multibusiness Marketing Activity

    Author : Magnus Ahlström; Lars-Gunnar Mattsson; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Offset; countertrade; industrial co-operation; systems selling; project marketing; package deal; turnkey; buying behaviour; governmental procurement; local content;

    Abstract : Offset, an advanced form of countertrade, is common in the international marketing of large infrastructure and defence systems. Offsets are activities that benefit the buying country for example in the form of local content, support of exports, subcontracts and technology transfer. READ MORE

    Abstract : Natural ventilation is the dominating ventilation process in ancient buildings like churches, and also in most domestic buildings in Sweden and in the rest of the world. These buildings are naturally ventilated via air infiltration and airing. READ MORE

  7. 5. Finite Difference Methods for Time-Dependent Wave Propagation Problems

    Author : Ylva Ljungberg Rydin; Ken Mattsson; Erik Sjöqvist; Magnus Svärd; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Finite differences; Wave propagation problems; Summation-by-parts; Simultaneous approximation term; High-order accuracy; Deforming domains; Point sources; Scientific Computing; Beräkningsvetenskap;

    Abstract : Wave propagation models are essential in many fields of physics, such as acoustics, electromagnetics, and quantum mechanics. Mathematically, waves can be described by partial differential equations (PDEs).  In most cases, exact solutions to wave-dominated PDEs are nearly impossible to derive. READ MORE
