Validating Software Functionality Across Combinations of Runtime Configurations

As the number of configurable attributes of software under test grows and the cardinality of those attributes increases, the efficiency of software verification rapidly declines. This disclosure describes techniques to determine test coverage gaps in multidimensional configuration spaces of substantial cardinality by enabling a software developer to define a set of rules associated with a feature and by forming a Boolean algebra over a coverage matrix that defines the required test coverage. Test coverage is tracked and presented on a dashboard. Release can be blocked automatically if the test coverage gap is beyond a threshold. Based on the coverage matrix, untested combinations of configurations can be detected and individual compatibility tests to verify functionality can be designed. By dynamically maintaining the allowed values of the configuration space, intelligent prioritization of coverage becomes possible. Software testability is sustained in the face of exponential dimensional growth

A qualitative assessment of using lay trainers with type 2 diabetes in an intervention programme for people at risk of type 2 diabetes

Objective: More knowledge is needed on the impact of expert patients within health intervention programmes. The University of East Anglia Impaired Fasting Glucose (UEA-IFG) feasibility programme was a structured dietary and exercise intervention to reduce the risk of type 2 diabetes mellitus (T2DM) in susceptible individuals. Lay volunteers with T2DM (T2 trainers) were recruited to support participants in adopting healthier lifestyles. This study aimed to explore the acceptability, perceived effectiveness and sustainability of lay trainers within the programme. Design: A qualitative focus group study. Setting: A clinical research unit in Norwich, United Kingdom (UK). Method: Focus groups were conducted with: (1) T2 trainers (n = 15); (2) programme participants who had received their support (n = 11); and (3) salaried staff facilitators who had worked alongside the T2 trainers (n = 3). Framework analysis was applied to identify the different experiences of the lay trainer role. Results: All groups perceived advantages for peer support, particularly in sharing the day-to-day experiences of living with T2DM. However, staff facilitators raised the importance of role boundaries, emphasizing that T2 trainers should not provide medical advice. Acceptability of T2 trainers was enhanced by contacting participants at a convenient time and before substantial lifestyle changes had been made. Conclusion: Lay trainers were seen as a complementary method to motivate individuals to reduce their risks of T2DM. A less prescriptive approach needs to be adopted to enable full integration of lay trainers, allowing them a greater level of contribution. To sustain effective use of lay trainers, health professionals need to work alongside volunteers and be trained to encourage peer involvement

NEPP Evaluation of Automotive Grade Tantalum Chip Capacitors

Automotive grade tantalum (Ta) chip capacitors are available at lower cost with smaller physical size and higher volumetric efficiency compared to military/space grade capacitors. Designers of high reliability aerospace and military systems would like to take advantage of these attributes while maintaining the high standards for long-term reliable operation they are accustomed to when selecting military-qualified established reliability tantalum chip capacitors (e.g., MIL-PRF-55365). The objective for this evaluation was to assess the long-term performance of off-the-shelf automotive grade Ta chip capacitors (i.e., manufacturer self-qualified per AEC Q-200). Two (2) lots of case size D manganese dioxide (MnO2) cathode Ta chip capacitors from 1 manufacturer were evaluated. The evaluation consisted of construction analysis, basic electrical parameter characterization, extended long-term (2000 hours) life testing and some accelerated stress testing. Tests and acceptance criteria were based upon manufacturer datasheets and the Automotive Electronics Council's AEC Q-200 qualification specification for passive electronic components. As-received a few capacitors were marginally above the specified tolerance for capacitance and ESR. X-ray inspection found that the anodes for some devices may not be properly aligned within the molded encapsulation leaving less than 1 mil thickness of the encapsulation. This evaluation found that the long-term life performance of automotive grade Ta chip capacitors is generally within specification limits suggesting these capacitors may be suitable for some space applications

Humidity Steady State Low Voltage Testing of MLCCs (Based on NESC Technical Assessment Report)

Review of the low voltage reduced Insulation Resistance (IR) failure phenomenon in Multilayer ceramic capacitors (MLCCs)and NASA approaches to contend with this risk. 1. Analyze published materials on root cause mechanisms. 2. Investigate suitability of current test methods to assess MLCC lots for susceptibility. 3. Review current NASA parts selection and application guidelines in consideration of benefits vs. disadvantages

Pro-oxidant effect of α-tocopherol in patients with Type 2 Diabetes after an oral glucose tolerance test – a randomised controlled trial

BACKGROUND: As a part of a larger study investigating the effects of α-tocopherol on gene expression in type 2 diabetics we observed a pro-oxidant effect of α-tocopherol which we believe may be useful in interpreting outcomes of large intervention trials of α-tocopherol. METHODS: 19 type 2 diabetes subjects were randomised into two groups taking either 1200 IU/day of α-tocopherol or a matched placebo for 4 weeks. On day 0 and 29 of this study oxidative DNA damage was assessed in mononuclear cells from fasted blood samples and following a 2 h glucose tolerance test (GTT). RESULTS: On day 0 there was no significant difference in oxidative DNA damage between the two groups or following a GTT. On day 29 there was no significant difference in oxidative DNA damage in fasted blood samples, however following a GTT there was a significant increase in oxidative DNA damage in the α-tocopherol treatment group. CONCLUSION: High dose supplementation with α-tocopherol primes mononuclear cells from patients with type 2 diabetes for a potentially damaging response to acute hyperglycaemia

Young people's experiences of managing Type 1 diabetes at university: a national study of UK university students

Aim: Little is known about the challenges of transitioning from school to university for young people with Type 1 diabetes. In a national survey, we investigated the impact of entering and attending university on diabetes self‐care in students with Type 1 diabetes in all UK universities. Methods: Some 1865 current UK university students aged 18–24 years with Type 1 diabetes, were invited to complete a structured questionnaire. The association between demographic variables and diabetes variables was assessed using logistic regression models. Results: In total, 584 (31%) students from 64 hospitals and 37 university medical practices completed the questionnaire. Some 62% had maintained routine diabetes care with their home team, whereas 32% moved to the university provider. Since starting university, 63% reported harder diabetes management and 44% reported higher HbA1c levels than before university. At university, 52% had frequent hypoglycaemia, 9.6% reported one or more episodes of severe hypoglycaemia and 26% experienced diabetes‐related hospital admissions. Female students and those who changed healthcare provider were approximately twice as likely to report poor glycaemic control, emergency hospital admissions and frequent hypoglycaemia. Females were more likely than males to report stress [odds ratio (OR) 4.78, 95% confidence interval (CI) 3.19–7.16], illness (OR 3.48, 95% CI 2.06–5.87) and weight management issues (OR 3.19, 95% CI 1.99–5.11) as barriers to self‐care. Despite these difficulties, 91% of respondents never or rarely contacted university support services about their diabetes. Conclusion: The study quantifies the high level of risk experienced by students with Type 1 diabetes during the transition to university, in particular, female students and those moving to a new university healthcare provider
