  2. 2. The Role of Top Management in Supply Chain Management Practices

    Författare :Erik Sandberg; Mats Abrahamsson; Håkan Aronsson; Per Åman; Jari Juga; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Logistics; Supply Chain Management; Strategy; Top management; Collaboration; Business studies; Företagsekonomi;

    Sammanfattning : Supply chain management (SCM) has been discussed by researchers as well as business practitioners for more than two decades now, but still surprisingly little of this philosophy can be seen in today’s business practices. One important enabler for taking the SCM philosophy from theory into practice that is often mentioned, but not investigated in-depth, is top management support. LÄS MER

  3. 3. SAWING STRATEGIES FOR TROPICAL HARDWOOD SPECIES : Simulation studies based on industrial conditions of Mozambique

    Författare :Pedro Ah Shenga; Dick Sandberg; Olof Broman; Mats Nylinder; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sawing strategies; tropical hardwood species; simulation; volume yield; log grading; umbila; jambirre; Träteknik; Wood Science and Engineering;

    Sammanfattning : The harvesting of Mozambique tropical hardwood species is considerable higher than the natural regrowth in the forest and the stock is decreasing drastically. Therefore, it is important to improve the material recovery when the wood is refined (i.e., in sawing and further refinement to products such as joineries, furniture etc. LÄS MER

  4. 4. Paper-based Supercapacitors

    Författare :Britta Andres; Håkan Olin; Mats Sandberg; Mittuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; graphene; graphite; paper; nano fibrillated cellulose; supercapacitor; electric double-layer capacitor; energy storage; roll-to-roll; coating; kinetic energy recovery;

    Sammanfattning : The growing market of mobile electronic devices, renewable off-grid energy sources and electric vehicles requires high-performance energy storage devices. Rechargeable batteries are usually the first choice due to their high energy density. However, supercapacitors have a higher power density and longer life-time compared to batteries. LÄS MER

  5. 5. Distribution of Ventilation Air and Heat by Buoyancy Forces inside Buildings : An Experimental Study

    Författare :Claes Blomqvist; Mats Sandberg; Per Heiselberg; Per Heiseberg; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building ventilation; thermal forces; buoyancy; gravity currents; large openings; heating; air quality; forced convection; free convection; Building engineering; Byggnadsteknik;

    Sammanfattning : The main task of the ventilation system in a building is to maintain the air quality and (together with the heating or cooling system) the thermal climate at an acceptable level within the building. This means that a sufficient amount of ventilation air at the appropriate temperature and quality must be supplied to satisfy thermal comfort and air quality demands and that this air is distributed to the parts of the building where people reside.
