Popular Abstract in Swedish Arbetet i denna avhandling berör elektroniska komponenter och hur de kan användas i kretsar för trådlös kommunikation. Den huvudsakliga slutsatsen av arbetet är att innovativa och icke konventionella komponenter kan bidra till att förbättra presentanda och minska effektförbrukningen i system för kommunikation på korta avstånd. Framförallt har en krets tillverkats som geShort high-frequency electromagnetic pulses, also referred to as wavelets, are considered for use in various short-range impulse based ultra-wideband applications, such as communication, imaging, radar, spectroscopy, and localization. This thesis investigates field-effect and tunneling based semiconductor devices and their operation in millimeter-wave (mm-wave) impulse transceivers. The main resea

Popular Abstract in Swedish Infektioner i urinvägar, tarm och luftvägar orsakas av bakterier som speciellt anpassats till respektive vävnad. Infektionen börjar med att bakterien binder till slemhinneytan, och därmed sätter igång inflammation och försvar. Urinvägsinfektioner (UVI) är en värdefull modell för att förstå de molekylära detaljerna som avgör balansen mellan värd och bakterie. UVI orsakaBacterial adhesion to the bladder mucosa is a critical step for the establishment of Escherichia coli bacteriuria. The P-fimbriae, encoded by the pap gene cluster, are considered as virulence factors but the mechanisms have been debated. This study defined the roles for P fimbriation during the early colonization of the human urinary tract. Patients with recurrent UTI were first subjected to deli

We have found the equations that determine the self-adjoint extensions, and thus the boundary conditions, of the differential operator used in the multi-band k·p-theory, when the coefficients in the Kane-matrix are piecewise constant. Both the one-dimensional and the three-dimensional case have been investigated. Numerical simulations of the energy eigenvalues in a quantum well has been performed,

The Orphic myth takes an important position through the history of poetry. Due to the cultural climate the myth has been assumed either to raise the position of the poet or to discuss the limitations of performed poetry. What I aim at in my thesis is to examine how the basic constellations of the myth are again made use of by Swedish poets during the period 1974-1995, and to give evidence of how a

The interaction of bi-isonicotinic acid (4,4[prime]-dicarboxy-2,2[prime]-bipyridine) with the Au(111) surface has been investigated using electron spectroscopic techniques. Near edge x-ray absorption fine structure (NEXAFS) spectra show that monolayers of the molecule lie flat to the surface and also reveal that the monolayer is sensitive to the preparation conditions employed. Core level x-ray ph

As organizations work to secure their innovativeness, they want to know whether their efforts are supporting the improvement of their innovation capabilities. The focus on outcomes and financial measures of current innovation measurement systems makes this challenging as those indicators often say little about capabilities. In addition, indicators are frequently focused at the organizational level

Efter att ha reflekterat över ett stort antal kursutvärderingar samt efter omfattande dialog med teknologer och lärare har jag valt att dela upp lärarkompetensen i fem delar: 1. Ämneskompetens 2. Pedagogisk kunskap och reflektionsförmåga 3. Klarsyn om hur studenter lär sig ämnet 4. Kommunikativ skicklighet 5. Förmåga att leda, planera och strukturera Denna roundtablesession ämnar att diskutera

Many student–industry activities have emerged in recent years, and universities have invested considerable time and energy in designing and implementing such collaboration models. However, as models differ significantly, student–industry activities should not all be bundled together. This paper examines student–industry activities conducted as integral parts of engineering study programmes. These
