A compact dual-element antenna suitable for ultrawideband (UWB) MIMO operation is proposed in this work. The size of the antenna is 25 mm by 40 mm and it covers the lower UWB band of 3.15-5.15 GHz. Apart from the inherent wideband isolation obtained through the different angle and polarization characteristics in the radiation patterns of the individual elements, the gap between the two antenna ele
Om utsläppen av växthusgaser ska minska bör utsläppen prissättas; en följd av detta kan bli att produktionen av biobränslen ökar. Rapporten handlar om hur olika styrmedel för att minska utsläppen av växthusgaser påverkar produktionen av biobränslen och hur ökad produktion av biobränslen påverkar livsmedelsmarknaden och marknaden för skogsprodukter.
Previous studies have convincingly argued that firms’ ability to efficiently utilize their resources is linked to the effectiveness of their routines and resources for pricing. The ability to appropriate value and achieve a more efficient resource utilization relative to competitors through routines and resources for pricing has been named pricing capability. If an effective pricing capability cou
A sustainable development of the built environment asks for changes in urban residents’ mobility patterns. The extensive use of the car contributes to sedentary lifestyle and negative environmental impact in many respects. Children living in urban areas are faced with limits of their independent use of the environment both in terms of travel and outdoor play. Many parents hold favourable attitudes
The paper looks at the development philosophy behind the establishment of the Lukzum Samdrupling, the first Tibetan refugee settlement in India and how it was received by the refugees. After reviewing Chinese development concepts in the 1950’s and 1960’s with an emphasis on Tibet, the paper explores the central concepts of Indian development philosophy at that time, such as cooperative, scientific
