This paper presents a QVCO and divider for a 28 GHz SiGe PLL. It was designed in a SiGe process with fT= 200 GHz. The PLL is intended to be used for beam steering in an 81-86 GHz E-band transmitter. Phase control is implemented by programmable current injection into the loop filter. The simulations in Spectre use a layout extracted view with parasitics for the QVCO and the frequency divider and an

Legacy streamer data and newer 3D ocean-bottom-cable data are cross-matched and analysed for time-lapse analysis of geomechanical changes due to production in the Valhall Field. The issues relating to time-lapse analysis using two such distinctly different data sets are addressed to provide an optimal cross-matching workflow that includes 3D warping. Additionally an assessment of the differences b

A large part of the Earth’s turnover of resources is associated with buildings and building construction. There is therefore a complex relationship to be taken into consideration when realizing construction projects, since economic and social aspects also affect individual people. In order to gain an overall perspective on this relationship during the construction process, one solution is to adapt

Detta projekt uppmärksammar brottsoffer och etnicitetsfrågor. I fokus står mellanmänskliga tolkningar av etnicitetens betydelse. Syftet är att analysera etnicitetstillskrivningar hos ungdomar som blivit utsatta för rån eller misshandel av andra ungdomar ”med annan etnicitet”. Med samtalsintervjun som metod studeras hur etnicitet omtalas och behandlas. Innebörden av begreppet är inte entydig, det i

In order to meet the demands of globalization, universities across the world are in the process of managing issues of multilingualism (Doiz et al. 2013; van der Walt 2013). In Sweden, since the passing of the Language Act in 2009, state-funded universities are obliged to use Swedish as their official language while also becoming increasingly internationalized. While the Language Act makes Swedish

Popular Abstract in Swedish Vid framtagning av nya produkter måste man utgå ifrån de behov som den blivande kunden ställer i form av krav och önskemål på produkten för att den ska vara intressant att inhandla och använda. För att säkerställa att den blivande produkten har de egenskaper som efterfrågas, används idag omfattande simuleringar av den blivande produktens egenskaper. Simuleringar består The current trend in industry to encourage engineering designers to take an active part in the analysis of their own design solutions is apparent in many companies today, domestically as well as abroad. From a research project with the objective to develop a computer-based design system for the design of lightweight grippers, one of the major difficulties was to overcome the system users’ lack of
