This paper presents a wideband LC quadrature voltage controlled oscillator (VCO) for novel TRPC-UWB transceiver in 0.13 μm CMOS technology. Based on series coupling structure, and through combining the advanced switched capacitor and MOS varactor techniques, this QVCO's continuous frequency tuning range covers from 5.05 to 5.84 GHz. The measured phase noise at 1 MHz offset from a 5.1 GHz carrier a

Recent research has shown that invariant indexing can speed up the recognition process in computer vision. Extraction of invariant features can be done by choosing first a canonical reference frame, and then features in this reference frame. This paper gives methods for extracting invariants for planar curves under affine and projective transformations. The invariants can be used semilocally to re

Summary. Proceeding from the assumption that metaphors as well as pictures are iconic signs, the present contribution studies what happens when metaphors occur in figurative pictures. The author distinguishes between primary iconicity, the reco¬gnition of which is a condition for the categorization of an object as a sign, and secondary iconicity, which is perceived only after an object has been ca

Upon request of the FEMM committee, this note provides an overview of the situation of women's rights and gender equality in Sweden focussing on recent developments. it notably covers the areas of equal participation in decision-making, women in the labour-market, reconciliation of private and professional Life, eradiction of gender-based violence, sexual and reproductive health and rights, gender

Exopolysaccharides (EPSs) produced by the lactic acid bacteria (LAB) Lactococcus lactis and Streptococcus thermophilus are important for the rheological behaviour and texture of a variety of fermented food products. Furthermore, EPSs from food-grade LAB have potential as food additives and functional food ingredients with both health and economic benefits. However, the production levels of EPSs fr

I artikeln behandlas de historiskt och kulturellt betingade motsättningarna mellan ”nordiskhet” och katolicism

The binaries PSR J1141-6545 and PSR B2303+46 each appear to contain a white dwarf that formed before the neutron star. We describe an evolutionary pathway to produce these two systems. In this scenario, the primary transfers its envelope on to the secondary, which is then the more massive of the two stars, and indeed sufficiently massive later to produce a neutron star via a supernova. The core of
