Identification of a real time of a change in a process, when an out-of-control signal is present is significant. This may reduce costs of defective products as well as the time of exploring and fixing the cause of defects. Another popular topic in the Statistical Process Control (SPC) is profile monitoring, where knowing the distribution of one or more quality characteristics may not be appropr...

In certain statistical process control applications, quality of a process or product can be characterized by a function commonly referred to as profile. Some of the potential applications of profile monitoring are cases where quality characteristic of interest is modelled using binary,multinomial or ordinal variables. In this paper, profiles with multinomial response are studied. For this purpo...

This paper investigates the relationship between education and unemployment in postapartheid South Africa, and probes the argument that employment growth has been inhibited particularly by skills constraints. We use probit regression analysis to show that higher education protected against unemployment in both 1995 and 2003, and that that these aggregate trends mask substantial variation among ...

This paper provides a rationale for choosing acoustic localisation techniques as an alternative to other principles to provide spatial positions in interactive locative audio applications (ILAA). By comparing positioning technology in existing ILAAs to the expected performance of acoustic positioning systems (APS), we can evaluate if APS would perform equivalently in a particular application. I...

Deducing what a paper is about, titles are considered as the most important determinant of how many people will read the article. Therefore, studying the use of different syntactic structures and their rhetorical functions in titles is of great significance. The current study was set to investigate these structures used in research article titles in three disciplines of Applied Linguistics, Den...

OBJECTIVES The authors sought to determine the diagnostic test characteristics of bedside emergency physician (EP)-performed ultrasound (US) for cholelithiasis in symptomatic emergency department (ED) patients. METHODS A search was conducted of MEDLINE, EMBASE, the Cochrane Library, bibliographies of previous systematic reviews, and abstracts from major emergency medicine conference proceedin...

AT THE FIRST software engineering (SE) conference in 1968, Doug McIlroy introduced the concept of software components during his keynote speech, “Mass-Produced Software Components.”1 That components hold such an esteemed place in SE history should come as no surprise: componentization is a fundamental engineering principle. Top-down approaches decompose large systems into smaller parts—componen...
