Supporting Run-time Monitoring of UML-RT through Customizable Monitoring Configurations in PapyrusRT
Resumo:
Model Driven Engineering uses the principle that code can automatically be generated from software models which would potentially save time and cost of development. By this methodology, a systems structure and behaviour can be expressed in more abstract, high level terms without some of the accidental complexity that the use of a general purpose language can bring. Models are the actual implementation of the system unlike in traditional software development where models are often used for documentation purposes only. However once the code is generated from the model, testing and debugging activities tend to happen on the code level and the model is not updated. We believe that monitoring on the model level could potentially facilitate quality assurance activities as the errors are detected in the early phase of development. In this thesis, we create a Monitoring Configuration for an open source model driven engineering tool called PapyrusRT in Eclipse. We support the run-time monitoring of UML-RT elements with a tracing tool called LTTng. We annotate the model with monitoring information to be used by the code generator for adding tracepoint statements for the corresponding elements. We provide the option of a timing specification to discover latency errors on the model. We validate the results by creating and tracing real time models in PapyrusRT.

Research and professional ethics are an integral part of every Psychology degree, as this is seen as a key graduate learning outcome for students leaving to become clinicians working with clients and patients. The development of these skills is embedded in teaching, but they culminate in the final year of a degree when final year students must gain formal ethical approval for their final research project. Decision as to the ethical appropriateness of research are made by a Departmental Research Ethics Committee, which considers all research project proposals submitted by staff and students within the department. One of the challenges of this practice is the scale of work involved for committee members (Doyle & Buckley, 2014) who are all faculty members, and the tracking of applications and decisions, alongside the quality assurance required to ensure that all applications are treated fairly and equally. The time involved in performing this work is often underestimated by Universities, and the variety and complexity of decisions requires extensive discussion and negotiation. Traditionally, these decisions are reached by committee discussions, however this presents logistical difficulties as it requires meetings with quorate attendance. The University of Westminster launched a virtual tool in 2014 to facilitate the management of the Research Ethics Committee, to help track the progress of applications and to allow discussions to occur and be managed virtually. The Department of Psychology adopted the tools in September 2014 to deal with all ethics applications. Here we report on how this virtual committee has affected the role and practices of a working committee that deals with over 300 applications per year, and how an online ethics procedure has facilitated an integrated developmental approach to ethical education.

This paper presents a vision that allows the combined use of model-driven engineering, run-time monitoring, and animation for the development and analysis of components in real-time embedded systems. Key building block in the tool environment supporting this vision is a highly-customizable code generation process. Customization is performed via a configuration specification which describes the ways in which input is provided to the component, the ways in which run-time execution information can be observed, and how these observations drive animation tools. The environment is envisioned to be suitable for different activities ranging from quality assurance to supporting certification, teaching, and outreach and will be built exclusively with open source tools to increase impact. A preliminary prototype implementation is described.

Introduction Quantitative and accurate measurements of fat and muscle in the body are important for prevention and diagnosis of diseases related to obesity and muscle degeneration. Manually segmenting muscle and fat compartments in MR body-images is laborious and time-consuming, hindering implementation in large cohorts. In the present study, the feasibility and success-rate of a Dixon-based MR scan followed by an intensity-normalised, non-rigid, multi-atlas based segmentation was investigated in a cohort of 3,000 subjects. Materials and Methods 3,000 participants in the in-depth phenotyping arm of the UK Biobank imaging study underwent a comprehensive MR examination. All subjects were scanned using a 1.5 T MR-scanner with the dual-echo Dixon Vibe protocol, covering neck to knees. Subjects were scanned with six slabs in supine position, without localizer. Automated body composition analysis was performed using the AMRA Profiler™ system, to segment and quantify visceral adipose tissue (VAT), abdominal subcutaneous adipose tissue (ASAT) and thigh muscles. Technical quality assurance was performed and a standard set of acceptance/rejection criteria was established. Descriptive statistics were calculated for all volume measurements and quality assurance metrics. Results Of the 3,000 subjects, 2,995 (99.83%) were analysable for body fat, 2,828 (94.27%) were analysable when body fat and one thigh was included, and 2,775 (92.50%) were fully analysable for body fat and both thigh muscles. Reasons for not being able to analyse datasets were mainly due to missing slabs in the acquisition, or patient positioned so that large parts of the volume was outside of the field-of-view. Discussion and Conclusions In conclusion, this study showed that the rapid UK Biobank MR-protocol was well tolerated by most subjects and sufficiently robust to achieve very high success-rate for body composition analysis. This research has been conducted using the UK Biobank Resource.

Purpose- Entrepreneurship education (EEd) plays a crucial role in the development of entrepreneurs and the enhancement of entrepreneurial activities in every economy. This paper examined what Higher education Institutions (HEIs) do in learning and teaching of entrepreneurship in general and how entrepreneurship development takes place in Nigerian HEIs. The outcome from this study will enable a deeper understanding on what HEIs do EEd, with more exposure as to what the areas and focus of research is in the Nigerian context. Design/methodology/approach- The study adopted a systematic literature review approach- drawing from a computerized search of five selected data bases, using predetermined key words by the researchers. Findings: The main finding of this paper is that, related concepts like skills, intention, drive and attitude have been use in expounding discussions on the outcome of EEd, but very little has been written on entrepreneurial mind-set (EMS), of which other studies have suggested that it’s a crucial point in the journey of an entrepreneurs (Reed & Stoltz, 2011; Quality Assurance Agency for Higher Education (QAA), 2012; Neneh, 2012). Furthermore, learning and teaching of entrepreneurship in Nigerian HEIs seems to be more on creating awareness (about entrepreneurship) than actual preparation for entrepreneurship (For entrepreneurship). Research limitations/implications- The paper is limited since it is based on a review of literature from a selected databases- covering a specific time span. This potentially excludes other studies outside this time span. A more comprehensive overview of these contributions would benefit from employing tools such as Google Scholar, for an overview of the sub–domains online. Originality/value – There are limited studies that focus on the issue of entrepreneurial mind-set in entrepreneurship education in Africa, specifically Nigeria. This paper and its focus in particular, have laid down pioneering ground work for research on entrepreneurial mind-set development in Nigerian entrepreneurship education.

Portland cement concrete (PCC) pavement undergoes repeated environmental load-related deflection resulting from temperature and moisture variations across the pavement depth. This phenomenon, referred to as PCC pavement curling and warping, has been known and studied since the mid-1920s. Slab curvature can be further magnified under repeated traffic loads and may ultimately lead to fatigue failures, including top-down and bottom-up transverse, longitudinal, and corner cracking. It is therefore important to measure the “true” degree of curling and warping in PCC pavements, not only for quality control (QC) and quality assurance (QA) purposes, but also to achieve a better understanding of its relationship to long-term pavement performance. In order to better understand the curling and warping behavior of PCC pavements in Iowa and provide recommendations to mitigate curling and warping deflections, field investigations were performed at six existing sites during the late fall of 2015. These sites included PCC pavements with various ages, slab shapes, mix design aspects, and environmental conditions during construction. A stationary light detection and ranging (LiDAR) device was used to scan the slab surfaces. The degree of curling and warping along the longitudinal, transverse, and diagonal directions was calculated for the selected slabs based on the point clouds acquired using LiDAR. The results and findings are correlated to variations in pavement performance, mix design, pavement design, and construction details at each site. Recommendations regarding how to minimize curling and warping are provided based on a literature review and this field study. Some examples of using point cloud data to build three-dimensional (3D) models of the overall curvature of the slab shape are presented to show the feasibility of using this 3D analysis method for curling and warping analysis.

The use of secondary data in health care research has become a very important issue over the past few years. Data from the treatment context are being used for evaluation of medical data for external quality assurance, as well as to answer medical questions in the form of registers and research databases. Additionally, the establishment of electronic clinical systems like data warehouses provides new opportunities for the secondary use of clinical data. Because health data is among the most sensitive information about an individual, the data must be safeguarded from disclosure.
