  1. 6. Vinterbyar : ett bandsamhälles territorier i Norrlands inland, 4500-2500 f. Kr

    Författare :Åsa Lundberg; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; social territory; local band; regional band; language family; settlement pattern; semi-sedentary; late mesolithic; neolithic; semi-subterranean house; winter sites; red slate; pit-falls; cooking pits; scrapers;

    Sammanfattning : The main archaeological features studied in this thesis are semi-subterranean house remains in the woodlands of middle northern Sweden, east of the high mountains and some 100 km from the coast. The period during which they were occupied has been delimited to 4500-2500 BC. LÄS MER

  3. 7. Biomass Retrieval in Topographic Boreal Forest using Polarimetric and Tomographic SAR in P- and L-band

    Författare :Erik Blomberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest Biomass; Tomography; SAR; L-band; EM Modelling; P-Band;

    Sammanfattning : Forests and their associated habitats are an integral part of Earth's biosphere and provide essential environmental services. There is an ever present need for accurate and economic monitoring of forest parameters such as biomass - of great interest both locally, for forest management and resource utilization, and globally as it represents stored atmospheric CO2 and one of the largest uncertainties in climate modelling.

  4. 8. Flaskor på löpande band : Arbete och arbetskraftsrekrytering vid Surte glasbruk 1943-1978

    Författare :Gunnel Holmér; Ulla Professor (befordrad); Mikael Docent; Ann-Catrin Östman; Linnéuniversitetet; []
    Nyckelord :HUMANIORA; HUMANITIES; glass-work; glass-workers; labour immigration; gender division of labour; durable inequality; glasbruk; glasarbetare; arbetskraftsinvandring; könsarbetsdelning; beständig ojämlikhet; Historia; History;

    Sammanfattning : This dissertation considers how the transition from craft manufacture to mechanized glass production affected the organization of work and the consequences for the recruitment of labour. Based on gender and ethnicity, the dissertation studies the composition of the workforce, the significance of qualifications, and differences in career paths and length of stay have been investigated at Surte glassworks 1943–1978.

  5. 9. Knotted Nodal Band Structures

    Författare :Marcus Stålhammar; Emil Bergholtz; Edwin Langmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Sammanfattning : It is well known that in conventional three dimensional (3D) Hermitian two band models, the intersections between the energy bands are generically given by points. The typical example are Weyl semimetals, where these singular points can be effectively described as Weyl fermions in the low energy regime. LÄS MER

  7. 10. Efficient Spectrum Utilization of Uhf Broadcast Band

    Författare :Lei Shi; Jens Zander; Ki Won Sung; Linda Dolye; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TV White Space; CellTV; UHF Band; Spectrum; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The UHF band between 470-790 MHz, currently occupied by digital ter- restrial TV (DTT) distribution in Europe, is widely regarded as a premium spectrum band for providing mobile coverage. With the exponential increase in wireless data traffic in recent years, there has been growing interests in gaining access to this spectrum band for wireless broadband services. LÄS MER
