Literature surveys, limited to the sensor technologies applicable for the functionalities of relevance for the “Safe Speed” and “Safe Distance” concept, were conducted on recent and undergoing development in the area of sensor technology. Various alternatives of combinations of sensors can serve for building the prototype for the Safe Speed and Safe Distance concept. However, one sensor alone can

Conventionally, the spacing between adjacent elements in an antenna array are set at half-a-wavelength in order to obtain maximum spatial resolution while avoiding spurious sidelobes. However, for antenna arrays that are implemented in a compact manner, the spacing between the adjacent elements can be significantly less than half-a-wavelength. The small spacing between the antennas results in stro

Popular Abstract in Swedish Trä är ett konstruktionsmaterial med många positiva egenskaper, både avseende mekaniska och tekniska egenskaper och avseende det som ibland kallas mjuka egenskaper. Trä har generellt hög styrka i förhållande till sin vikt, det är ett naturligt förnybart material och det anses av många vara estetiskt tilltalande. Jämfört med andra vanliga konstruktionsmaterial som stål oThis thesis concerns experimental and theoretical work regarding perpendicular to grain fracture in wooden structural elements. The experimental part concerns strength tests of glulam beams with a hole. The theoretical parts concern development of two models for strength and fracture analysis, both based on fracture mechanics approaches, and their application to analysis of beams with a hole and d

We have investigated CO adsorption at 300 K on ∼ 1.5 atomic layer thick Pd films on a Mo(110) surface by high-resolution core level photoemission. We describe how high-resolution core level spectroscopy may be utilized to study the influence of laterally mobile states on the sticking probability of molecules on such a laterally heterogeneous surface. The present Pd films are laterally heterogeneou

A grazing-incidence grating spectrometer has been used for the investigation of the undulator radiation from beamline 411 at MAX-lab. The direct detection of undulator light is expected to obtain the information of the quality of the undulator. Regular undulator radiation and some higher harmonics were observed. The effects of electronic beam coupling and Landau cavities have been studied. The exp

A strong low-energy shake-up satellite for CO adsorbed on Pd is observed. The occurrence of the satellite is established for the CO/1 ML Pd/Mo(110) system at a coverage where CO adsorbs exclusively on-top. Comparisons with CO adsorbed on Pd single-crystal surfaces and small supported Pd particles indicate that the strongly increased satellite intensity is due to the decreased CO-Pd interaction str

Learning is a highly individual process. Some prefer learning by reading the course material, others learn best by listening to a lecture, whilesome like to learn in a trial-and-error way by themselves in a laboratory assignment. A good learning scheme is individual. A scheme that is good for some persons might not at all be good scheme for someone else. It is important to understand your own pers

In this paper I use Kenneth Burke's theory of aesthetic form from Counter-Statement (1931) to analyze how the gourmet chef Mathias Dahlgren creates a gourmet dinner.

In this article, Oevdalian referential null subjects are introduced and analysed. A general background to Oevdalian is provided, whereupon the syntactic restrictions of the possible null subjects (wįð ('we') and ið ('you')) are presented. Interestingly, these null subjects do not appear in the same syntactic positions; whereas null ið seems to be unrestricted, null wįð may only appear in positions

High-resolution core-level spectroscopy is used in combination with low-energy electron diffraction (LEED) and photoelectron diffraction to identify the adsorption sites for three different coadsorbed phases consisting of ordered overlayers of oxygen coadsorbed with CO on the Rh(111) single-crystal surface. The three ordered overlayer structures, which may be denoted as 2O + CO/Rh(111), O + CO/Rh(

During epididymal maturation, sperm acquire the ability to swim progressively by interacting with proteins secreted by the epididymal epithelium. Beta-defensin proteins, expressed in the epididymis, continue to regulate sperm motility during capacitation and hyperactivation in the female reproductive tract. We characterized the mouse beta-defensin 41 (DEFB41), by generating a mouse model with iCre

We report the first discovery since the 1970s of a new extant family (Aenigmatineidae fam.n.) of homoneurous moths, based on the small Aenigmatinea glatzella sp.n. from Kangaroo Island off southern Australia. It exhibits a combination of extraordinary anatomical characters, and, unlike most homoneurous moths, its larva is a conifer-feeder (stem mining in Callitris, Cupressaceae). While the adult's

Müllerian mimicry among Neotropical Heliconiini butterflies is an excellent example of natural selection, associated with the diversification of a large continental-scale radiation. Some of the processes driving the evolution of mimicry rings are likely to generate incongruent phylogenetic signals across the assemblage, and thus pose a challenge for systematics. We use a data set of 22 mitochondri
