Abstract in UndeterminedFor assembly tasks, the knowledge of both trajectory and forces are usually required. Consequently, we may use kinesthetics or teleoperation for recording human demonstrations. In order to have a more natural interaction, the operator has to be provided with a sense of touch. We propose a bilateral teleoperation system which is customized for this purpose. We introduce diff
The ratio of the proton elastic electromagnetic form factors, GEp/GMp, was obtained by measuring Pt and P, the transverse and longitudinal recoil proton polarization components, respectively, for the elastic epepreaction in the four-momentum transfer squared range of 0.5 to 3.5 GeV2. In the single-photon exchange approximation, GEp/GMp is directly proportional to Pt/P. The simultaneous measurement
The purpose of the research program Towards Sustainable Waste Management has been to assemble, develop and evaluate ideas for policy instruments for a more sustainable waste management. The waste management should contribute to reducing the environmental impact of the society, for example through reduced waste quantities and increased recycling. It should be cost-efficient and also be accepted amo

Many cryptographic primitives rely on word rotations (R) and xor (X) to provide proper mixing. We give RX-system mixing a very general treatment and deduce some theoretical results on related probability distributions. Pure RX-systems are easy to break, so we show how to apply our theory to a more complex system that uses RX operations in combination with S-boxes. We construct an impractical (key
Jobs and economic growth are created where businesses are located and investments made. A number of factors affect where firms choose to locate and where and how much that is invested. Many of these factors are hard to influence in the short run while others are governed by politicians and can be designed in order to stimulate desirable business and investment behaviour. One such factor is taxatio

The objective of the paper is to present the through-flow design of a twin-shaft oxy-fuel turbine. The through-flow design is the subsequent step after the turbine mean-line design. The through-flow phase analyses the flow in both axial and radial directions, where the flow is computed from hub to tip and along streamlines. The parameterization of the through-flow is based on the mean-line results
Popular Abstract in Swedish I Sverige drabbas årligen så många som 100.000 personer av benbrott, höftfrakturer och sjukdomar, som kan kopplas till benskörhet. Under normalt åldrande ändras benets struktur och täthet vilket ökar risken för benbrott. Man vet att förändringarna förorsakas av förändringar i skelettets förmåga att ombildas. Under hela livet byts benvävnaden successivt ut och ersätts avDiffusion in bone is needed for bone remodeling and bone healing. Understanding the phenomenon is often important for comprehension bone diseases. Mathematical modeling of the diffusion processes is a required prerequisite in the study of this important physical process in living bone tissue. A proper model is crucial in order to obtain realistic results. An easily accessible method to measure the
Today’s societies have to reach out for improved healthcare solutions due to the increased number of patients and changed disease profiles represented by the dominance of cardiovascular and neurodegenerative diseases as well as various forms of cancer that require customized therapies. There is an extensive need for diagnostic and therapeutic biomarkers that may also become targets for drug develo
Short essay on The Terminator (1984)
Repetitive DNA is quantitatively the main component of telomeres and centromeres, structures responsible for maintenance of the eukaryotic chromosome. The telomere is the specialized nucleoprotein complex that terminates linear chromosomes. In most species the DNA component consists of short repeats which are generated by the enzyme complex telomerase. However, there are important exceptions such
A-kassorna har inte bara förlorat många äldre medlemmar sedan avgifterna höjdes kraftigt 1 januari 2007. De har tappat en ännu större andel av de yngre medlemmarna. Det har tidigare uppmärksammats att många ”miljonärer” lämnade a-kassan, men det var ännu fler med skulder större än tillgångar som hoppade av eller avstod från att gå med när avgifterna när alliansregeringen höjde avgifterna. Under år
Popular Abstract in Swedish Under de senaste decennierna har intresset för smärta och smärtbehandling ökat påtagligt. Etablerade smärttillstånd är ofta svårbehandlade och medför stora och kostnadskrävande insatser i sjukvården. Produktionsbortfall och stigande sjukförsäkringskostnader medverkar också till stora samhällseffekter. Om långvarig smärta i viss utsträckning kunde förebyggas och om behanThe aim was to study the epidemiology of chronic pain (> 3 months duration) and factors associated to pain prevalence, prognosis, health care and medication in a general population. A cross-sectional mailed survey to a random population sample (n = 1806) was followed by a clinical examination and a prospective study of three selected groups. Pain related diagnoses from primary health care was moni
Under senare delen av 1800-talet och en bit in på 1900-talet genomgår filosofiämnet vid samtliga nordiska universitet en förändring som kan beskrivas som ett modernt genombrott. Förändringsprocessen består väsentligen i att idealistiska systemfilosofier av den typ som hegelianismen och boströmianismen representerar utmanas av nyare riktningar som positivism, värdeidealism och livsfilosofi.
