Self-calibration from Image Derivatives for Active Vision Systems

In this paper we show how to calibrate a camera, mounted on a robot, with respect to the intrinsic camera parameters when the so-called hand-eye transformation between the robot hand and the camera is unknown. The calibration is based directly on the spatial and temporal derivatives in an image sequence and do not need any matching and tracking of features or a reference object. The calibration is

2nd and 3rd generation electrodes for biosensors and biofuel cells

Popular Abstract in English The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing domain whereas both PDH and

Multi-Element PAA Calibration with REV Method

Phased array antenna (PAA) calibration is the process of determining the PAA channel characteristics; these characteristics are used in beam forming algorithms. In "contactless" PAA calibration methods, measurements are made by a stationary probe antenna placed away from the tested antenna, and the channel characteristics are determined from the measured data. Two of these methods are the MTE and

Birger Sjöbergs bilder och Tegnérs

The metaphors in the works of Birger Sjöberg is compared to those of Esaias Tegnér. The comparison is made in the theoretical frame of Riffaterre´s concept of hypogram (clichés, descriptive system) and the tradition of domesticating metaphors. Sjöberg is clearly developing Tegnér's metaphorical technique, thus shaping new ways of expressing the depths of mans psyche and his fate, understood within

Three-terminal ballistic junctions: New building blocks for functional devices in nanoelectronics

Present digital logic gates are primarily built from field effect transistors (FETs) such as complementary metal oxide semiconductors with the gate length in the deep sub-μm regime. As device feature sizes approach the nanometer regime, fundamental physical constraints and increasingly prohibitive economic costs will make further miniaturization in electronic circuits difficult, and this has motiv

Comparison of vulnerability and reliability analysis of technical infrastructures

The society depends on reliable and robust services provided by technical infrastructures for its function. The impact of large-scale outages due to the inherent vulnerabilities of technical infrastructures has been demonstrated, for example, by the power outage in the U.S. in 2003 and the power outages in Sweden due to the storms Gudrun in January 2005 and Per in January 2007. Two of the main app

Use of calcium channel blockers as antihypertensives in relation to mortality and cancer incidence: a population-based observational study

Abstract Purpose Treatment with blood pressure lowering drugs may reduce morbidity and mortality. However, the efficacy and effectiveness may differ between antihypertensive agents. The current investigation aimed to compare mortality and cancer incidence in hypertensive patients treated with calcium channel blockers (CCB) or with other antihypertensive drugs (AHD). Methods All patients in two o

Mellan vanor och faror : ett kulturanalytiskt perspektiv på äldre människors bruk av läkemedel

Denna studie avser att undersöka den mening som mediciner skapar, och hur de påverkar människors vardagliga erfarenheter och identitetsskapande. Medicineringens relation till kroppsliga tecken och symptom påvisar den spänning som finns i synen på läkemedlet; mediciner som något farligt och riskfyllt men samtidigt med förmåga att förebygga och bota. Mediciners farlighet tycks delvis kunna motverkasThis study aims to explore the meaning that is created when using medicines, and how medicines affect older people’s experiences of everyday life and their identity. The connection between medicines and the body demonstrates the tension that the medications contain; something dangerous and unsafe but with the power to cure and prevent illness. The risks of medications seem to be counteracted throu
