Control loop noise rejection using fuzzy logic.

This paper describes an application of fuzzy logic to noise rejection in a control loop. This new use of fuzzy logic solves the problem of sluggish control loop response when using a set-point range to stop constant valve chattering due to noise in the output signal being sent to a control valve. Multiple related variables and a general understanding of their inter-relationship must be available for this method to be successfully applied. An overview of the specific fuzzy logic method used for this application is presented along with guidelines for the practical application. In addition, this paper includes results from the successful implementation of fuzzy logic to a control loop on a pilot plant distillation column.

Eczema--practical management issues.

BACKGROUND: Eczema is a common, and at times challenging, condition to manage. It often involves an irritable child, concerned parents and numerous return visits. A variety of mainstream and alternative treatments can confuse both the clinician and patient. OBJECTIVE: This article aims to refresh readers by reviewing evidenced based treatment protocols, and exploring some of the new and evolving treatments in eczema. DISCUSSION: Managing eczema is a multifocal task involving a variety of medicinal and practical approaches. Education of parents and carers is critical. Having a clear plan that can be adapted to each patient's needs is helpful for all involved, with management focussing on control rather than cure. Simple emollients and preventive measures are used to reduce heat, dryness and prickling of the skin. Topical corticosteroids remain the gold standard in the treatment of the inflammation of eczema. However, combining topical steroids with the new calcineurin inhibitors, wet dressings and behavioural modification should increase the time interval between exacerbations.

Bridging child welfare and juvenile justice: preventing unnecessary detention of foster children.

Gaps in service coordination between child welfare and other child-serving agencies are well documented. This article examines the gap between the child welfare and juvenile justice systems and discusses a program, Project Confirm, designed to reduce the problems associated with this gap. Project Confirm aims to improve cooperation between juvenile justice and child welfare agencies to prevent the unnecessary detention of arrested foster children in secure facilities. The program's design is outlined, and implementation statistics and government partner perceptions of the program in its first year of operations are provided. The article also identifies future challenges to implementation and discusses the broader implications of the program. In making this appeal for coordination and collaboration among public agencies, I'm not talking about pro forma integration efforts-I'm not talking about memoranda of understanding or top-level reorganizations that have autonomous agencies vaguely reporting to a single box labeled "human services." Rather, I'm talking about the much more challenging objective of achieving real working partnerships at the front line. (Nelson, 1998, p. 6)
