The aim of this paper is to analyze how a permanent magnet linear generator for wave power behaves when the stator slots are closed. The usual design of stator geometry is to use open slots to maintain a low magnetic leakage flux between the stator teeth. By doing this, harmonics are induced in the magnetic flux density in the air-gap due to slotting. The closed slots are designed to cause satu...

Soft x-ray optics can use narrow slots to direct x-rays into a desirable pattern on a focal plane. While square-pack, square-pore, slumped optics exist for this purpose, they are costly. Silicon (Si) is being examined as a possible low-cost replacement. A fabrication method was developed for narrow slots in <110> Si demonstrating the feasibility of stacked slot optics to replace micropores. Cur...

A novel and effective hyperthermia applicator utilizing a circular arc phased array of longitudinal slots in narrow wall of rutile-loaded rectangular waveguide is presented and analyzed in this paper. This configuration is mainly intended as a specialized and very effective applicator for hyperthermia treatment of tumor within curved portions of human body such as abdomen, neck, chest etc. Each...

SOCLE is a hybrid representation system in which cells of constraints are identified with slots of frame networks. Constraint formulas are maintained with respect to slots in frame networks and in turn provide for the dependency regulation of values on the frames. This paper illustrates the use of SOCLE and outlines the control structure decisions made for its design and implementation.

Heterogamous marriages, in which partners have dissimilar attributes (e.g. by socio-economic status or ethnicity), are often at elevated risk of dissolution. We investigated the influences of heterogamy by religion and area of residence on risk of marital dissolution in Northern Ireland, a country with a history of conflict and residential segregation along Catholic-Protestant lines. We expecte...

The paper introduces a language for representing knowledge in a declarative form. With this language it is possible to define knowledge about a certain domain by introducing a number of concepts and by specifying their interrelations. The paper is meant to be an informal introduction to the language. We present the available constructs, describe their meaning and present a number of examples. I...
