Relative Vapor-pressure Measurements Using A Frequency-modulated Tunable Diode-laser, A Tool For Water Activity Determination In Solutions

Two-tone frequency modulation spectroscopy (TTFMS) is applied to the determination of water activity using an 820-nm GaAlAs diode laser. By measuring the relative light absorption of water vapor over a solution and over a pure water reference, the water activity in the solution is determined. Fast, nonintrusive, and selective measurements are demonstrated. The detection limit for measuring a relat

Mobile access to biological databases on the Internet.

We have developed a new way of accessing biological databases and bioinformatics applications on the Internet. This new service, bioinformatics wireless application protocol (BioWAP) service, which is accessible by mobile devices makes it possible to access bioinformatics services, where normal PC or personal digital assistant (PDA) connections are not feasible. The BioWAP service includes major b

View Planning and Refractive Modeling for Structure and Motion

Popular Abstract in Swedish Avhandlingen berör det så kallade "struktur och rörelse"-problemet som är centralt inom datorseendefältet. Målet är att givet tvådimensionella bilder av ett föremål, kunna återskapa dess tredimensionella form och koordinater i rummet, dvs strukturen, samtidigt med kamerans position relativt objektet i varje bild, dvs rörelsen. Inom robotiken kallas tekniken för "simultaThis thesis presents contributions to structure-and-motion estimation, a central topic in the field of geometric computer vision. In particular, the problem of view planning is considered, and continuous and discrete optimization-based algorithms are given for how to plan the path of a sensor to its destination, while balancing the competing goals of path length and reconstruction accuracy. The sa

Purification, crystallization and preliminary X-ray diffraction analysis of human chondroadherin.

Chondroadherin is a cartilage matrix protein that is known to mediate the adhesion of isolated chondrocytes. Its protein core is composed of 11 leucine-rich repeats flanked by cysteine-rich domains at the N- and C-terminal ends. Recombinant human chondroadherin was crystallized using the sitting-drop vapour-diffusion method. The crystals belong to the monoclinic space group P2(1), with unit-cell p

Grain - A stream cipher for constrained environments

A new stream cipher, Grain, is proposed. The design targets hardware environments where gate count, power consumption and memory is very limited. It is based on two shift registers and a non-linear output function. The cipher has the additional feature that the speed can be increased at the expense of extra hardware. The key size is 80 bits and no attack faster than exhaustive key search has been
