The possibility of building compact, low-ohmic antennas suitable for mobile handsets is investigated. An F-antenna is built with a self-impedance of 10 Ω instead of the commonly used 50 Ω. Low impedance is chosen to minimize voltages in circuits prior to the antenna, in this case an adaptive matching network designed in CMOS or a similar process. To optimize this adaptive matching network, the ant

IKEA is a product developing company, known for putting packaging and logistics issues at the top of its agenda. At IKEA, the product and the packaging are developed concurrently with the aim of lowering the total cost from the supplier to the customer. During the years 2002 to 2004, a pckaging redesign project was conducted at IKEA. The purpose of the project was to redesign the packaging for an

Bioaerosols include bacterial cells and spores, viruses, pollen, fungi, algae, detritus, allergens and cell fragments. Bioaerosol particles are usually a small fraction of all aerosol particles in our surroundings, but their impact can be critical. They are a means for transmission of disease, they cause allergic reactions and they have effects on the global climate, ecology and biodiversity. This

A previous article by the author demonstrated that the supplier of corrugated board in the relationship studied cannot be considered a strategic supplier. Despite this, the manufacturing company has chosen to go through with the efforts of supplier integration with the supplier of corrugated board. This indicates a difference in the driving forces and the future nature of the relationship between

The paper presents design considerations for a digital Cellular Neural Network. The architectural spectrum is categorized from a rich variety in nodal structural transformations and formulated by an exploration model. This model is then applied to study the influence of the memory band-gap. Experiments show the benefits of a tiled implementation, mixing spatial network parallelism with time-multip

In their introductory chapter to the anthology "MEDIER & POLITK: Om arbetarrörelsens mediestrategier under 1900-talet", the two editors present a brief history of the ways in which the Swedish Labor Movement has used and related to various media during the last hundred years.

Ferromagnetic Single Electron Transistors (F-SETs) comprise ferromagnetic electrodes connected to a ferromagnetic- or non-magnetic central island via tunnel barriers. These devices are important for studies of spin-transport physics in confined structures. Here we describe the development of a novel type of AFM-assembled nano-scale F-SETs suitable for spin-transport investigations at temperatures
