  1. 1. Green Logistics Networks : Roles & Symbiotic Relationships

    Författare :Mary Catherine Osman; Maria Huge-Brodin; Linea Kjellsdotter Ivert; Jonas Ammenberg; Arni Hallordsson; Statens väg- och transportforskningsinstitut; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Logistics actors such as the transport buyer, freight forwarder, and haulier are currently in a transition phase towards more sustainable practices typically referred to as Green Logistics Practices (GLPs). One of the more progressive GLPs is completion of freight transport using fossil-free fuels such as biomethane. LÄS MER

  3. 2. Entrepreneurship in Russia: Western Ideas in Russian Translation

    Författare :Oksana Shmulyar Gréen; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Russia; entrepreneurship; capitalist development; Western business education; Russian marchants; Soviet managers; middle classes; networks;

    Sammanfattning : Aim of this thesis is to outline, both historically and in our own time, the development of entrepreneurship in Russia, a country where the very existence of the phenomenon has for a long period of time been either denied or confined to the margins of illegality and semi-legality. The primary focus of this work is on the emergence of a new generation of entrepreneurs that came to thrive in the 1990s, the most turbulent but also the most promising years of Russia’s economic, political, and social transformation.

  4. 3. Towards Green Wireless Access Networks : Main Tradeoffs, Deployment Strategies and Measurement Methodologies

    Författare :Sibel Tombaz; Jens Zander; Ki Won Sung; Ben Slimane; Peter Legg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; wireless access; green radio; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Wireless access networks today consume 0.5 percent of the global energy. Rapidly growing demand for capacity will further increase the energy consumption. Thus, improving energy efficiency has a great importance not only for environmental awareness but also to lower the operational cost of network operators. LÄS MER

  5. 4. Improving diagnosis of acute coronary syndromes in an emergency setting: A machine learning approach

    Författare :Michael Green; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ensemble; artificial neural network; machine learning; acute coronary syndrome; electrocardiogram; case based explanation; decision support system;

    Sammanfattning : Acute coronary syndrome (ACS) is the biggest people killer in the western world today. Despite well trained physicians and reliable diagnostic tools, diagnosing ACS early in the emergency departments (ED) remains a challenge. LÄS MER

  7. 5. Provisioning Strategies for Transparent Optical Networks Considering Transmission Quality, Security, and Energy Efficiency

    Författare :Amornrat Jirattigalachote; Lena Wosinska; Paolo Monti; Biswanath Mukherjee; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transparent optical networks; routing and wavelength assignment; physical-layer impairments; signal quality; differentiation of services; physical-layer attacks; power equalizers; Greedy Randomized Adaptive Search Procedure GRASP ; green networks; energy awareness; dedicated path protection; shared path protection; survivable WDM networks;

    Sammanfattning : The continuous growth of traffic demand driven by the brisk increase in number of Internet users and emerging online services creates new challenges for communication networks. The latest advances in Wavelength Division Multiplexing (WDM) technology make it possible to build Transparent Optical Networks (TONs) which are expected to be able to satisfy this rapidly growing capacity demand.
