In this paper we present one approach to understand palpability from the perspective of eco-systems of palpable devices. We will introduce the notion of Palpable Interaction Ecology that particular focus upon the properties that emerge from the interaction between people, their practices and palpable devices. This approach is derived from research into the use of pervasive healthcare services that
Accurate system planning and performance evaluation requires knowledge of the joint impact of scheduling, interference, and fading. However, current analyses either require costly numerical simulations or make simplifying assumptions that limit the applicability of the results. In this paper, we derive analytical expressions for the spectral efficiency of cellular systems that use either the chann
The change in capacitance, if an object is introduced in a parallel plate capacitor, is analyzed. The integral representation of the potential is exploited in a systematic way to solve the potential everywhere inside the capacitor. In particular, the change in capacitance is extracted. The method shows similarities with the null eld approach to solve dynamic problems.
Abstract in UndeterminedIn this paper, the orthogonality of dual-polarized MIMO channels with Rician fading is investigated in a measured urban macrocellular scenario. Overall, efficient two-stream MIMO communication can be achieved as more than 70% of the measured route achieves better channel orthogonality than the average performance of the reference IID Rayleigh channel. Furthermore, the study
Although a substantial body of theoretical as well as empirical work emphasizes the role of the mass media in constructing what could serve as a political public sphere at the European level, strikingly little is known, in qualitative terms, about opinion-making journalists’ underlying views and orientations on the European integration process. The point of departure in the present paper is that o
The proton beam of the Florida State University Tandem Van de Graaff Accelerator is being used to make quantitative determinations of the composition of particulate matter found in the atmosphere. Proton scattering using 16 MeV incident particle energy is employed to resolve the light elements (up to Cl), while elements Al and heavier are observed via proton induced X-ray emission analysis.
