The Loran Integrity Performance Panel (LORIPP) completed its 18 month study of the ability of Loran to meet aviation requirements for Required Navigation Performance 0.3 (RNP 0.3) in March 2004. The study examined the ability of Loran to meet on the RNP 0.3 requirements on integrity, availability, and continuity and provide a design for “enhanced Loran” which would allow Loran to reasonably pro...

BACKGROUND AND OBJECTIVES Family medicine residents are required to maintain a continuity practice in an approved family medicine center (FMC) and achieve minimum targets for patient encounters. In the past, minimum periods of time in the FMC were defined in the program requirements, but these have now been replaced with target numbers of patient encounters. As residency programs come under inc...

PN (point-normal) triangles are cubic Bézier triangles which meet at their edges to surface a triangular mesh, but this only achieves G0 continuity. We define blending regions that span the edges shared by adjacent pairs of triangular domains and blend the corresponding Bézier triangles using a univariate blending function formulated in terms of barycentric coordinates. This produces G2 continu...

In this paper, we investigate a relaxation of the C continuity conditions between functional, triangular Bézier patches, allowing for patches to meet approximately C. We analyze the cross boundary continuity of functional triangular Bézier patches, and derive a bound for the discontinuity in the normals between two patches based on their control points. We test our discontinuity bound on a simp...

The Loran Integrity Performance Panel (LORIPP) is to complete its 18-month study of whether an enhanced Loran system, which includes modernized equipment, new receiving equipment, and updated operating procedures, could meet aviation requirements for Required Navigation Performance 0.3 (RNP 0.3) in March 2004. There are four primary areas that must be examined in order to demonstrate RNP 0.3 – ...

OBJECTIVE Recent studies indicate that many preschoolers meet diagnostic criteria for psychiatric disorders. However, data on the continuity of these diagnoses are limited, particularly from studies examining a broad range of disorders in community samples. Such studies are necessary to elucidate the validity and clinical significance of psychiatric diagnoses in young children. The authors exam...

Quasicontinuity is a generalisation of Scott’s notion of continuous domain, introduced in the early 80s by Gierz, Lawson and Stralka. In this paper we ask which cartesian closed full subcategories exist in qCONT, the category of all quasicontinuous domains and Scottcontinuous functions. The surprising, and perhaps disappointing, answer turns out to be that all such subcategories consist entirel...

Abstract. A remarkable result due to Kou, Liu & Luo states that the condition of continuity for a dcpo can be split into quasi-continuity and meet-continuity. Their argument contained a gap, however, which is probably why the authors of the monograph Continuous Lattices and Domains used a different (and fairly sophisticated) sequence of lemmas in order to establish the result. In this note we s...

UNLABELLED The Clinical Data Ware House needs to meet three functions: reporting quality indicators, clinical research, and continuity of care. This paper reports on one function, namely the development and testing of data exchange for continuity of nursing care for oncology patients. The proof of principle was carried out using system analysis, requirements setting, system design, system devel...

BACKGROUND Review of the literature reveals a need to develop a questionnaire that measures patient perceptions of factors impacting continuity of care following discharge from hospital. Such a measure has the potential to guide quality improvement initiatives related to continuity of care. OBJECTIVE Our objective was to develop and examine the psychometric properties of a measure that would ...
