Monitoring self-adaptive applications within edge computing frameworks: A state-of-the-art review
Recently, a promising trend has evolved from previous centralized computation to decentralized edge
computing in the proximity of end-users to provide cloud applications. To ensure the Quality of Service
(QoS) of such applications and Quality of Experience (QoE) for the end-users, it is necessary to employ
a comprehensive monitoring approach. Requirement analysis is a key software engineering task in the
whole lifecycle of applications; however, the requirements for monitoring systems within edge computing
scenarios are not yet fully established. The goal of the present survey study is therefore threefold:
to identify the main challenges in the field of monitoring edge computing applications that are as yet
not fully solved; to present a new taxonomy of monitoring requirements for adaptive applications orchestrated
upon edge computing frameworks; and to discuss and compare the use of widely-used cloud
monitoring technologies to assure the performance of these applications. Our analysis shows that none of
existing widely-used cloud monitoring tools yet provides an integrated monitoring solution within edge
computing frameworks. Moreover, some monitoring requirements have not been thoroughly met by any
of them
Developing and operating time critical applications in clouds: the state of the art and the SWITCH approach
Cloud environments can provide virtualized, elastic, controllable and high quality on-demand services for supporting complex distributed applications. However, the engineering methods and software tools used for developing, deploying and executing classical time critical applications do not, as yet, account for the programmability and controllability provided by clouds, and so time critical applications cannot yet benefit from the full potential of cloud technology. This paper reviews the state of the art of technologies involved in developing time critical cloud applications, and presents the approach of a recently funded EU H2020 project: the Software Workbench for Interactive, Time Critical and Highly self-adaptive cloud applications (SWITCH). SWITCH aims to improve the existing development and execution model of time critical applications by introducing a novel conceptual model—the application-infrastructure co-programming and control model—in which application QoS and QoE, together with the programmability and controllability of cloud environments, is included in the complete application lifecycle
Remote Control Aircraft for SAE Aero Design West Competition
The purpose of this project was to design a remote controlled aircraft for the Society of Automotive Engineers 2018 Aero Design West competition. Students were tasked to employ knowledge of aerodynamics, structural mechanics, control systems, electrical engineering, and design principles to create an airworthy submission. Using various analysis tools, the team designed, constructed, and tested an aircraft capable of carrying 7 pounds of payload for the prescribed competition flight pattern, which limited the takeoff distance to 200 feet and required a circular flight pattern followed by a controlled landing and stop. The 12-foot wingspan aircraft is constructed mostly from foam and aluminum, and conforms to all competition specifications, with the exception of the electric motor power
The Security imaginary: Explaining military isomorphism
This article proposes the notion of a security imaginary as a heuristic
tool for exploring military isomorphism (the phenomenon that
weapons and military strategies begin to look the same across the
world) at a time when the US model of defence transformation is
being adopted by an increasing number of countries. Built on a critical
constructivist foundation, the security-imaginary approach is contrasted
with rationalist and neo-institutionalist ways of explaining
military diffusion and emulation. Merging cultural and constructivist
themes, the article offers a ‘strong cultural’ argument to explain why a
country would emulate a foreign military model and how this model is
constituted in and comes to constitute a society’s security imaginary.Web of Scienc
Improving quality of breast cancer surgery through development of a national breast cancer surgical outcomes (BRCASO) research database
<p>Abstract</p> <p>Background</p> <p>Common measures of surgical quality are 30-day morbidity and mortality, which poorly describe breast cancer surgical quality with extremely low morbidity and mortality rates. Several national quality programs have collected additional surgical quality measures; however, program participation is voluntary and results may not be generalizable to all surgeons. We developed the Breast Cancer Surgical Outcomes (BRCASO) database to capture meaningful breast cancer surgical quality measures among a non-voluntary sample, and study variation in these measures across providers, facilities, and health plans. This paper describes our study protocol, data collection methods, and summarizes the strengths and limitations of these data.</p> <p>Methods</p> <p>We included 4524 women ≥18 years diagnosed with breast cancer between 2003-2008. All women with initial breast cancer surgery performed by a surgeon employed at the University of Vermont or three Cancer Research Network (CRN) health plans were eligible for inclusion. From the CRN institutions, we collected electronic administrative data including tumor registry information, Current Procedure Terminology codes for breast cancer surgeries, surgeons, surgical facilities, and patient demographics. We supplemented electronic data with medical record abstraction to collect additional pathology and surgery detail. All data were manually abstracted at the University of Vermont.</p> <p>Results</p> <p>The CRN institutions pre-filled 30% (22 out of 72) of elements using electronic data. The remaining elements, including detailed pathology margin status and breast and lymph node surgeries, required chart abstraction. The mean age was 61 years (range 20-98 years); 70% of women were diagnosed with invasive ductal carcinoma, 20% with ductal carcinoma in situ, and 10% with invasive lobular carcinoma.</p> <p>Conclusions</p> <p>The BRCASO database is one of the largest, multi-site research resources of meaningful breast cancer surgical quality data in the United States. Assembling data from electronic administrative databases and manual chart review balanced efficiency with high-quality, unbiased data collection. Using the BRCASO database, we will evaluate surgical quality measures including mastectomy rates, positive margin rates, and partial mastectomy re-excision rates among a diverse, non-voluntary population of patients, providers, and facilities.</p
Diaspora identification and long-distance nationalism among Tamil migrants of diverse state origins in the UK
Accounts of Tamil long-distance nationalism have focused on Sri Lankan Tamil migrants. But the UK is also home to Tamils of non-Sri Lankan state origins. While these migrants may be nominally incorporated into a 'Tamil diaspora', they are seldom present in scholarly accounts. Framed by Werbner's (2002) conception of diasporas as 'aesthetic' and 'moral' communities, this article explores whether engagement with a Tamil diaspora and long-distance nationalism is expressed by Tamil migrants of diverse state origins. While migrants identify with an aesthetic community, 'membership' of the moral community is contested between those who hold direct experience of suffering as central to belonging, and those who imagine the boundaries of belonging more fluidly - based upon primordial understandings of essential ethnicity and a narrative of Tamil 'victimhood' that incorporates experiences of being Tamil in Sri Lanka, India and in other sites, despite obvious differences in these experiences. © 2013 Taylor & Francis

The health care costs of childhood obesity in Australia : an instrumental variables approach
The effect of childhood obesity on medical costs incurred by the Australian Government is estimated using five waves of panel data from the Longitudinal Study of Australian Children, which is linked to public health insurance administrative records from Medicare Australia. Instrumental variables estimators are used to address concerns about measurement error and selection bias. The additional annual medical costs due to overweight and obesity among 6 to 13 year olds is about $43 million (in 2015 AUD). This is driven by a higher utilisation of general practitioner and specialist doctors. The results suggest that the economic consequences of childhood obesity are much larger than previously estimated
