Series of finite dimensional representations of the superalgebras spl(p,q) can be formulated in terms of linear differential operators acting on a suitable space of polynomials. We sketch the general ingredients necessary to construct these representations and present examples related to spl(2,1) and spl(2,2). By revisiting the products of projectivised representations of sl(2), we are able to ...

The current exposure limits of mineworkers to physical pollutants, under the Mine Health and Safety Act3 is 85 dB LAeq,8h, with a peak sound pressure level of 135 dB(A). However, the sound pressure level (SPL) of machines is generally determined according to the methods and procedures defined in SABS-ISO 3744 under free field conditions as defined in Appendix 3 of the same standard. While SPL a...

Refactoring is a staple of Object-Oriented (OO) program development. It should be a staple of OO Software Product Line (SPL) development too. X15 is the rst tool to support the refactoring of Java SPL codebases. X15 (1) uses Java custom annotations to encode variability in feature-based Java SPLs, (2) projects a view of a SPL product (a program that corresponds to a legal SPL con guration), and...

Software product line (SPL) is an approach that develops the family of similar software by maximizing the reusability of development artifacts. Together with commonality, variability that differentiates a product from others plays a pivotal role in SPL. During decades lots of variability mechanisms have been developed for software development, and they have been used in SPL as they are. And new...

The amount and quality of the SPL drug knowledge which has been released so far is assessed. All published labels were loaded into a relational database and classified to create vendor-independent descriptions. While SPL labels cover only 23% of RxNorm clinical drugs, they still describe 78% of actual community pharmacy dispenses records. SPL descriptions agree well with RxNorm. SPL can be used...

Software Product Lines (SPL) is a methodology focusing on systematic software reuse, multiple benefits have been reported as a result of this type of software development. However, establishing a SPL is not a simple task. It is a challenging activity raising many challenges for engineering and management. This research aims to manage the risks during SPL development to provide traceability amon...

Nine of the physiological leaf spot mutants were described and investigated linkage relation with marker genes. All of them were governed by single recessive genes respectively and the causal genes were designated as a series of spl (spotted leaves) as spl,, spl,......sf&. With eight of them except for sPZ~, the linkage groups were determined as follows: sj+-a linkage group corresponding to A t...

OBJECTIVES This study sought to assess the value of the Health Level 7/U.S. Food and Drug Administration Structured Product Labeling (SPL) drug knowledge representation standard and its associated terminology sources for drug-intolerance (allergy) decision support in computerized provider order entry (CPOE) systems. DESIGN The Regenstrief Institute CPOE drug-intolerance issue detection system...

A software product line (SPL) is a family of software products that share a set of common features. Exhaustively testing every product of an SPL is a difficult task due to the combinatorial explosion of the number of products. Several sampling approaches have been proposed to select a set of products that can be used to test SPL. However, these approaches do not scale very well, especially for ...

The pathophysiology of idiopathic dystonic torticollis is unclear and there is no simple test that confirms the diagnosis and excludes a psychogenic or voluntary torticollis in individual patients. We recorded EMG activity in the sternocleidomastoid (SCM) and splenius capitis (SPL) muscles of eight patients with rotational torticollis and eight age-matched controls, and analysed the signals in ...
