This method has been applied to telecommunications systems and usually uses redundant hardware and special recovery software to restore the system after hardware and software failures. We propose a simple practical analytical approach to availability evaluation of systems with several recovery procedures based on a new 'segregated failures' model. To illustrate this method, it is applied to availability evaluation of a Lucent Technologies Reliable Clustered Computing application. Detailed numerical results are provided and the impact of various types of failures and coverage factors on down time is analysed.

We aim to describe the incidence of OOHCA, survival from OOHCA, and the impact of improved pre-hospital care on survival from OOHCA. A retrospective registry was established using multi-source information to assess survival from cardiac arrest following the introduction of several improvements in pre-hospital emergency medical care from 2003. Survival from OOHCA, from asystole/pulseless electrical activity, and from ventricular tachycardia/ventricular fibrillation was estimated. Adjusted per 100 000 population annual incidence rates from national population census data were calculated. Mean and median emergency medical services (EMS) response times to OOHCA calls were assessed. A total of 962 OOHCAs occurred from 1 January 2003 until 31 December 2008. Sixty-nine per cent (69%, n = 664) were male. Seventy-two per cent (72%, n = 693) occurred at home with 28% occurring in a public venue. Of these public v...

Infra Red thermography offers the ability to non-destructively test, key critical to quality attributes of medical devices during laser welding and facilitates real time statistical process control for enhanced product quality and yield. This paper will present results of research work focused on non-destructive methods using Infra Red Thermography to potentially replace destructive methods of assessment for laser welded joints in stent delivery catheters. The approach utilizes designed experiments in conjunction with IR assessment and also identifies some limitations of the proposed method.

These practical approaches try to extend students' learning beyond the theoretical disciplinary focus inside the universities and engage them in acquiring knowledge and more importantly skills they will need in their professional life. To do so, two schematic storyboards have been drawn based on the experiences of some Iranian experts including students, entrepreneurs and academics represented through some focus groups. The titles of these storyboards are: “Business Plan Writing”, and “Tentative start-up of a business”. Our primary focus is on defining some technical and pedagogical capabilities in an e-learning platform based on the three groups of experts' experiences as well as principals of experience-based learning, enabling both students and tutors to use them for creating a more practical, real and effective teaching-learning environment. Before drawing each storyboard four descriptive components named Functional Specifications (FS) have been written, trying for defining different aspects of the storyboards. These components have been generated based on the participants' experiences and then supports from the literature has been extracted and added to these FSs. While the paper is written from an e-learning perspective, the issues and processes raised are applicable to any higher education system that seeks to value and reward practical and experience-based education.
