This thesis addresses powder manufactured (P/M) components, with special attention to the compaction process and to the sensitivity to damage accumulation due to fatigue within powder compacted specimens. Three dimensional simulations of the compaction process have been performed, using an explicit dynamic dilatant finite strain finite element code supplemented with the effects from contact fricti

This work focuses on the use of the Tröger´s base as organic scaffold for the construction of synthetic receptors for different classes of organic molecules. The structural properties of the Tröger's base, i.e. chirality, rigidity and curvature, allow for synthetic modifications towards the recognition of different molecules. While the concave nature of the TB offers the geometrical frame for rec

The increasing complexity of product chains is an argument for analysing actors and policy instruments throughout the lifecycle of products. Actors are persons or corporations deciding upon the fate of the product. The policy instruments refer to well-known measures like information, economic or administrative measures. The theoretical part of the study discuss governance and the role of policy in

This paper presents preliminary results of a project with the aim to achieve a deeper understanding of how the design process and its ICT tools may support the development towards industrialised building. The project focuses on the construction process for multi-storey dwellings, and how object-oriented ICT-tools may be designed to enable different technical solutions as well as competition among

A low frequency algorithm designated for the calculation of the magnetic and the electric energies and the ohmic losses of passive components has been developed. These quantities can be used to achieve the inductance, the capacitance, the resistance, and the Q-value of the inductor at low frequencies. The method is based on an iterative scheme in which the different fields, such as the electric po

"Installationsbrandskydd" omfattar tekniska lösningar för brandskydd av ventilation - rör - el. Tanken är att ge en samlad bild av integrationen mellan installationers brandskydd i en byggnad. Boken vill även tjäna som vägledning vid projektering av brandskydd för byggnaders installationer. Den berättar var man finner samhällskraven, vilka lagar och föreskrifter som gäller för byggverksamhet.

Popular Abstract in Swedish Isocyanater är en grupp kemiska ämnen som används vid tillverkning av polyuretanplast (PUR). PUR ingår bland annat i färg, lim, lack och skumgummi, vilka förekommer i många olika produkter i vår miljö. Produktionen och användningen av PUR-produkter ökar. Vid den industriella tillverkningen av PUR kan arbetare exponeras för isocyanater och då drabbas av olika besvär så sThe aromatic isocyanates, toluene diisocyanate (TDI) and methylenediphenyl diisocyanate (MDI), are used in the production of polyurethane (PUR) foams, paints, elastomers and glues. The use of isocyanates is increasing, and exposure to isocyanates is the most common cause of occupational asthma. Biomarkers of TDI and MDI were determined as the corresponding amines, toluenediamine (TDA) and methyle

Popular Abstract in Swedish I detta arbeta har reaktionerna 16O(γ,p)15N och 18O(γ,p)17N studerats med hjälp av reella fotoner. Fotonerna med vilka syrekärnorna har bestrålats har varit i energiområdet 50 - 70 MeV. De utgående laddade partiklarna såsom protoner, deuteroner och tritoner har detekterats med hjälp av två ΔE-ΔE-E teleskop placerade i 70o respektive 110o relativt fotonstrålen. De två 0.A measurement of the reactions 16O(γ,p)15N and 18O(γ,p)17N have been made with tagged photons in the energy range Eγ ≈ 50 – 70 MeV. The protons have been detected in ΔE-E telescopes with silicon strip detectors as ΔE detectors and HPGe crystals as E detectors. Two telescopes have been used with an average angle towards the photon beam of 70 and 110 degrees. The silicon strip detectors have been us

Speaker age is a speaker characteristic which is always present in speech. Previous studies have found numerous acoustic features which correlate with speaker age. However, few attempts have been made to establish their relative importance. This study automatically extracted 161 acoustic features from six words produced by 527 speakers of both genders, and used normalised means to directly compare
