Interference between femto-cell systems is a critical factor for the deployment of such systems in, e.g., resedential areas. In this paper we report on a residential channel measurement campaign focusing on the channel properties for femtocell systems. We characterize basic channel properties such as delay spread and interference levels between different furnished residential houses. In addition w
In this paper we describe the first decades of the history of the Swedish ATM (Automated teller machine). Sweden was one of the pioneers in using ATMs, starting with cash dispensers or cash machines in 1967. The first machine was made operational and shown to the press on July 6, 1967, in Uppsala at Upsala Sparbank, only one week after the first cash machine in the world was made operational in th
Popular Abstract in Swedish Europaparlamentet vill minska primärenergianvändningen samt minska beroendet av energiimport till unionen (EU Direktiv 2012/27/EU). Ett hjälpmedel för att uppnå detta mål kan vara användandet av individuell mätning och debitering (IMD) av värme och varmvatten i flerbostadshus. IMD innebär att boende i flerbostadshus endast ska betala för deras egen konsumtion, vilket skIndividual metering and charging (IMC) means that tenants in multi-apartment buildings should pay only for their own energy consumption, which gives an economic incentive for energy-conscious behaviour. In April, 2014, Swedish legislation about energy metering in buildings (SFS 2014:267) was passed by the Swedish Parliament as an implementation of the EU Energy Efficiency Directive 2012/27/EU. The
It is well known that planar self-complementary structures have a constant input impedance and hence they are good candidates for ultra-wideband antennas. However, introduction of a ground plane breaks the symmetry and destroys the broadband property. In this paper, it is shown that stacking of dielectric slabs above the antenna elements can reduce the degrading eject of the ground plane. The diel
Information and Communication Technology (ICT) is arguably the most important, emblematic and ubiquitous technology of contemporary society. We see ICT used increasingly in new product areas and help resolve problems and challenges to mankind; it has even gotten to a point where life without ICT is hard to imagine. For many incumbent firms, the infusion of ICT into their industries poses both thr
Following public sector reforms inspired by New Public Management, new structures and processes intended for actors to coordinate their activities have been introduced in the public sectors in Northern Europe since the 1980s. Partly, the focus on structural change has evolved around creating market-like structures.Quasi-markets can be regarded as a structure for governance where market mechanisms
Close reading of Ingmar Bergman's last film, Saraband (2003).
This paper reflects and analyzes upon a research and pedagocial development project “Gender perspectives on university education and academic disciplines - a pedagogic project for the development of teaching – an intersectional approach (financed by the Swediah Council for Renewal of Higher Education). The project aims to further develop pedagogical models for the inclusion and integration of a “g
The current family of 802.11 protocols are based on the Carrier Sense Multiple Access (CSMA) mechanism which is a simple and robust means of sharing a channel. However, two current trends in wireless networks point towards a situation where CSMA fails to perform better than pure random access solutions such as ALOHA. The first trend is the ever increasing raw data rate in each generation of 802.11
