National Report on the Energy Efficiency Service Business in Sweden

The ChangeBest project is supported by the Intelligent Energy Europe Programme of the European Commission. The purpose of the project is to promote the development of an energy efficiency service (EES) market. The project provides good practice examples of changes in energy service business, strategies, and supportive policies and measures in the course of the implementation of Directive 2006/32/E

Dense Tracking and Mapping with a Quadrocopter

In this paper, we present an approach for acquiring textured 3D models of room-sized indoor spaces using a quadrocopter. Such room models are for example useful for architects and interior designers as well as for factory planners and construction man- agers. The model is internally represented by a signed distance function (SDF) and the SDF is used to directly track the camera with respect to the

Physical limitations of antennas in a lossy medium

The dissipated power and the directivity of antennas in a homogeneous, lossy medium are systematically analyzed in this paper. The antennas are ideal and located inside a lossless sphere. In the lossy space outside the sphere, the electromagnetic fields are expanded in a complete set of vector wave functions. The optimal values of the radiation efficiency, the directivity, as well as the power gain a

Time-domain direct and inverse scattering for bianisotropic slabs at oblique incidence

Using the Cayley-Hamilton theorem and unique solubility of scalar Volterra convolution equations of the second kind, the inverse problem of determining the four time-dependent susceptibility dyadics of a linear, homogeneous, bianisotropic slab from generic scattering data at oblique incidence is shown to be well posed. An explicit formula for the crucial step is given.

Preservation of lexical tones in singing in a tone language

Lexical tones are important for expressing meaning and usually have high priority in tone languages. This can create conflicts with sentence intonation in spoken language and with melodic templates in singing since all of these are transmitted by pitch. The main question in this investigation is whether a language (in our case the Mon-Khmer language Kammu) with a simple two-tone system uses simila

Key issues on sharing and transformation of lessons from experiences by actor organisations in the aviation industry

This paper sets out generic requirements including principles of system theory, organizational learning and operational readiness, for a learning system in the aviation sector. On the basis of our analysis we derived a number of key issues for sharing and transforming lessons from experiences. These issues highlight the critical role of context transformation, the use of performance data, and the
