Connectivity in wireless sensor networks may be established using either omnidirectional or directional antennae. The former radiate power uniformly in all directions while the latter emit greater power in a specified direction thus achieving increased transmission range and encountering reduced interference from unwanted sources. Regardless of the type of antenna being used the transmission co...

As described in earlier papers in this series, approximately 10,000 persons, mainly children between the ages of 3 months and 18 years, were given the Sabin oral poliovirus vaccine in Middletown, Connecticut, early in 1961. Among the objectives of the program was the detection of any contra-indications or untoward effects which might follow the use of the oral vaccine. The following discussion ...

— This paper systematizes some theory concerning the generation of -groups and reduced f -rings from substructures. We are particularly concerned with archimedean and hyperarchimedean groups and rings. We discuss the process of adjoining a weak order unit to an -group, or an identity to an f -ring and find significant contrasts between these cases. In -groups, hyperarchimedeanness and similar p...

Computerized maintenance management systems (CMMS) are required to manage and control asset, plant, and equipment maintenance in today’s hospitals. A CMMS is much more than just a way to schedule preventive maintenance (PM). By using a CMMS, you can create equipment logs to record events associated with a piece of equipment; create work orders automatically according to a schedule or manually f...

Conceptual combination refers to the cognitive process by which people combine two or more concepts to represent a new conceptual entity. Literature has studied the primary interpretive strategies of a conceptual combination denoted by two nouns (e.g., robin snake): relation-linking (e.g., a robin snake is a snake that eats robins) and property-mapping (e.g., a robin snake is a snake that has r...

System requirements often express some of the behavior of a domain model in the form of policies, constraints, invariants, and rules. Although an object-oriented approach helps with the design of this model, the implementation is often cluttered with details necessary to enforce the model's policies and constraints. As a result, the code is more prone to error and is more difficult to maintain ...

A commercially available C6 ELISA kit was used to detect antibodies induced by natural infection with Borrelia burgdorferi in dogs that lived in an area endemic for Lyme disease. Rates of infection were determined both for nonvaccinated dogs and those that had been vaccinated with a whole-cell B. burgdorferi bacterin (Lyme Vax, Fort Dodge Animal Health) before 6 months of age and were boostered...
