A dual-band CMOS front-end was designed and fabricated in a 0.18 μm CMOS process. The front-end employs a common-gate low noise amplifier (LNA) with capacitive cross coupling (CCC) technique and a passive mixer. The band selection is performed by switching a capacitor in and out of the LNA load, changing the resonance frequency between 2.2GHz and 4.0GHz. The measured noise figure is below 3.5dB fo

How can qualitative and emotional aspects from users be mapped at the same time as they get something meaningful in return? This case study has developed the use of cultural probes [1] with a selection of ten families with small children in the Öresund region. The idea was to evoke thoughts about recreation and living for the probe users while providing information and inspiration to the scientist

This work contrasts conservative or minimally mutilating revisions of empirical theories as they are identified in the presently dominant AGM model of formal belief revision and the structuralist program for the reconstruction of empirical theories. The aim is to make understandable why both approaches only partly succeed in substantially informing and formally restraining the issue. With respect

Human postural dynamics was investigated in twelve normal subjects by means of a force platform recording body sway induced by bipolar transmastoid galvanic stimulation of the vestibular nerve and labyrinth. We modeled the stabilizing forces actuated by the feet as resulting from complex muscular activity subject to feedback of body velocity and position. Time series analysis demonstrated that a t

This paper discusses a method for abnormal motion detection and its real-time implementation on a smart camera. Abnormal motion detection is a surveillance technique that only allows unfamiliar motion patterns to result in alarms. Our approach has two phases. First, normal motion is detected and the motion paths are trained, building up a model of normal behaviour. Feed-forward neural networks are

Poland holds great potential for bioenergy. However, biomass production from dedicated energy crops has not developed at a pace that was hoped. Clearly, there are barriers hindering farmers. The aim of this research was to directly explore the farmers’ perspective on barriers to growing dedicated energy crops in Poland. During the on-the-ground research conducted in Poland the perceptions regardin

Popular Abstract in Swedish Att mäta kroppsställningar och rörelser under arbete Belastningsskador är vanliga och medför höga kostnader, både för de drabbade och för samhället. Kvinnor som arbetar med repetitivt arbete, t.ex. monteringsarbete och livsmedelshantering (fiskberedning och kycklingslakt), drabbas ofta, särskilt i nacke, axlar, armar och händer. De åtgärder som genomförts på arbetsplatWork-related musculoskeletal disorders of the neck and upper limb are a major problem. Women in repetitive manual work is one large affected group. Preventive actions are hampered by the lack of knowledge regarding quantitative exposure-response relations for physical workload. The present work shows, that available electrogoniometers are, with a sampling frequency of 20 Hz, feasible for measurin
