The mechanical properties of major arteries may reflect early manifestations of vascular disease and are also of interest because they are important for cardiac work. Using echo-tracking sonography and blood pressure measurements, arterial stiffness and diameters were investigated in healthy individuals as well as in patients with insulin dependent diabetes mellitus (IDDM) or alpha1-ant
Improved add-compare-select and branch metric units are presented to reduce the complexity in the implementation of trellis-based decoding architectures. These units use a complementary property of the best rate 1/2 convolutional codes to reduce both area requirements and power consumption in a silicon implementation with no loss in decoding performance. For a 0.13μm CMOS process, synthesized comp
The problem addressed in this paper is how to allocate the environmental aspect of transports to the cargo transported. The cargo type was limited to high volume, low value cargo. The problem was also addressed from a transport purchasing perspective. The research was both case study inspired as well as action research oriented. The model was developed in a company where the researcher actively pa
Alltsedan det kalla kriget slutade har försvarssektorn, framförallt militär logistik och försvarsmaterielanskaffning, genomgått en genomgripande transformation. Flera faktorer har bidragit till transformationen: förändringar i länders och organisationers försvars- och säkerhetspolitik; reducerade försvarsbudgetar; deltagande i fredsbevarande och fredsframtvingande operationer; erfarenheter från deSince the ending of the Cold War, the defence sector, particularly the areas of military logistics and defence acquisition, has been undergoing a comprehensive transformation. There are several factors that explain this transformation: changes in defence and security policies for nations and organisations; reductions in defence expenditure; participation in Peace Support Operations; Lessons Learne
We investigate the effects of fracture- and inclusion-induced seismic anisotropy in a carbonate reservoir rock and the resulting influence this anisotropy may have on surface seismic data. Whole-core velocity measurements made on a carbonate sample from the Gulf of Mexico show evidence of elastic anisotropy. Constraints on the style of this anisotropy are obtained from comparisons with effective m
The problem of reducing the number of multiplications in infinite response filtering is considered. We show how this operation may be decomposed on finite response filtrations and so-named halfconvolutions. Examples of the efficient procedures for filters of low order are presented.
Popular Abstract in Swedish Tensider är amfifila molekyler, vilket innebär att de består av två delar. En av dessa är hydrofil (”vattenälskande”) och den andra är hydrofob (”vattenhatande”). Detta faktum ger tensider speciella egenskaper av vilken den viktigaste är att de självaggregerar i lösningsmedel (främst vatten), och bildar olika typer av aggregat, varav micellen är den mest kända. Dess spePhase diagrams of mixed alkylglucoside surfactants, n-nonyl-b-D-glucopyranoside and n-decyl-b-D-glucopyranoside (C9G1 and C10G1) have been examined for the purpose of determining the microstructure surrounding a closed-loop miscibiliyt gap. There are large deuterium isotope effects on the phase diagram. NMR-self diffusion, cryoTEM and TRFQ experiments show the presence of long interconnect network
Concerns have been raised about the marketization of science through the prevailing funding regime. However, the present article will discuss how it comes that the potentially marketable stem cell science is not more commercialized than what is currently the case. We approach this question by analysing discursive pluralism in defining the value of stem cells within a grant allocation process. More
The aim of this paper is to evaluate static and dynamic characteristics of a two-phase claw-pole motor. The static characteristics are calculated and measured respectively for a single phase-core assembled into the motor and for a complete motor. The dynamic characteristics of the motor are evaluated on the basis of non-linear static characteristics. Later, the control system that is designed in s

Underinvestment happens when an investor abstain from investing in an asset, even if the investment is beneficial for the customer, because it does not perceive a profitable return on the specific investment. The risk for underinvestment is high in projects which rely on high asset specificity and towards the end of contract lifespan. This paper builds upon a qualitative analysis of documentation
