This paper examines application of AEDSYS and MATLAB design tools to virtually fly an engine in a platform through a mission. The primary objective of this effort was to develop the procedures for this process as an instructional tool. The secondary objective was application of the process to an actual case study, the re-engine of the B-1A. The resulting modular software uses performance data from engine models for the F101, F119, and a cadet designed engine built in AEDSYS; a B-1A drag polar model; as well as atmospheric and geospatial mapping tools available in MATLAB. The resulting simulation provides a relatable means of presenting this complicated information. This tool gives the cadets the opportunity to virtually fly their engine. This visualization gives them full insight into how the integrated system performs. Aside from providing a great means of discussing many aspects for consideration in engine design, it also provides an incentive to develop a higher performance engine through competition.

Secondary Objective

The primary objective of this study was to assess the characteristics of patients admitted for COVID-19, ‘J18.9 Pneumonia, unspecified organism’ and other types of diagnoses. The aim was to assess as to what extent do COVID-19 related admissions changed to pneumonia, and as to what extent do ‘J18.9 Pneumonia, unspecified organism’ related admissions that changed to COVID-19 diagnosis at discharge stage. The secondary objective of the study was to assess’ predictors of readmissions in private hospitals. The review period was private hospital claims received by the scheme between January and August 2020. The inclusion criteria for COVID-19 admissions were patients that had a laboratory-confirmed (RT – PCR assay) COVID-19. Predictors of readmissions were modelled using logistic regression. The study found that restricted scheme patients admitted for a COVID-19 diagnosis changed to a ‘J18.9 Pneumonia, unspecified organism’ diagnosis. The converse was found to be true in that some patients that were admitted as J18.9 Pneumonia, unspecified organism’ diagnosis changed to a COVID-19 diagnosis. This study showed underlying factors associated with hospital admissions and predictors of readmissions in private hospitals.

The Difference

The primary objective of the research was to compare the viscosity parameters of the same viscosity grade engine oils, as declared by the manufacturers, to the actual laboratory measurements. The secondary objective was to briefly investigate (1) what kind of information oil manufacturers provide in the product data sheets of the studied oils, and (2) the potential savings resulting from the use of the energy efficient oils. The study material consisted of 42 selected synthetic engine oils that belong to the 5W-30 viscosity grade. Stabinger SVM 3001 viscometer was used to determine kinematic viscosity at −20 °C, 40 °C, 100 °C and 130 °C. The HTHS (high temperature high shear), CCS (cold cranking simulator), FTIR (Fourier-transform infrared spectroscopy) and GC (Gas Chromatography) measurements were also performed for the samples that had the lowest and the highest kinematic viscosity. Large differences (5–25%) between oil producers’ declarations and the results of laboratory tests were found. Although all of the engine oils tested met the 5W-30 grade standards, the high variability of viscosity measurements needs to be reported. The difference between the oil with the highest and the oil with the lowest kinematic viscosity at −20 °C was 11,804 mm2/s. The outlying temperature-related viscosity profiles were recovered using Mahalanobis distances which identified 16 out of 42 analyzed oil samples as atypical.

Insight Into

In this case study, I examine the ways adult learners improve skills and practices around communication, problem-solving, motivation, self-esteem, and technology through engagement in a makerspace curriculum focused on composition. A primary objective is to provide insight into the various ways that adult education environments can incorporate innovative practices of teaching and learning to prepare students for a standardized high school equivalency test and beyond. The patterns in the data revealed that makerspaces for the focal participants predominantly supported nonacademic skill development, particularly learning from mistakes, the importance of learning from each other, and identifying as a learner to aid in one’s learning.

Purpose The purpose of this paper is to provide a contextual analysis that helps explain how socio-cultural factors are negatively impacting the evolution of the entrepreneurial ecosystem in a struggling regional economy. Design/methodology/approach A case study method is used to provide a detailed contextual analysis triangulating primary and secondary data. Findings This paper provides insight into a region impeded from embracing the benefits of innovation-driven entrepreneurship in fostering economic development. The authors show that socio-cultural factors may be inhibiting the region from having a functional entrepreneurial ecosystem that can support innovation. Specific aspects of culture and social capital weaknesses are identified and insight into the potential causes of these impediments were offered. As well, the paper shows how the fundamental nature of culture may be affecting other elements of the entrepreneurial ecosystem from maturing. Originality/value This paper adds to a small, but growing, body of literature that is illustrating the evolutionary nature of entrepreneurial ecosystems and the significant impact of socio-cultural attributes to that evolution. This paper responds to calls to investigate contexts in which innovation does not thrive and where economic challenges prevail. The value of this research paper is to provide conceptual contributions in a contextual analysis from which other researchers can draw comparisons, insights and inspiration for similar approaches. Despite the abundance of research discussing the importance of culture, there are very few actual case studies showing concrete examples of culture and its influence on a region’s entrepreneurial ecosystem.

The primary objective of this case study is to discuss a retail business information system illustrating an e-business integration example among a biometric attendance system, a surveillance system, and a point-of-sale system. Using a service-oriented architecture allows businesses to build on top of legacy applications or construct new applications in order to take advantage of the power of Web services. Over the past years, Web services have finally developed enough to allow such basic architectures to be built. Each of the components in the system will be designed and developed using a service-oriented architecture that clearly illustrates how such cutting-edge systems can be put together. By designing these components in such a fashion, this example will focus on applying service-oriented development and integration techniques to the retail sector. The result of this project will be an integrated system that can be used by businesses everywhere to learn how their organizations can benefit from serviceoriented architecture. Also, the application of the service-oriented development and integration to systems that were previously stand-alone and heterogeneous is discussed. All previous experiences in object-oriented architectures and design methodology are naturally streamlined with the service-oriented architecture, supporting the loose coupling of software components.

PurposeFacility design standardization strategy has considerable advantages, highlighted by its widespread and consistent use in the shipbuilding and manufacturing industries. However, capital projects have failed to realize these benefits. The primary rationale behind this problem is the lack of proper understanding of design standardization, more specifically the benefits and equally importantly, the trade-offs of design standardization in capital projects. Therefore, this study highlights 13 benefits and six trade-offs of standardization in connection to design standardization, along with specific examples.Design/methodology/approachTo achieve the study objectives, the researchers identified the most impactful benefits and trade-offs in terms of economic impact by surveying prominent players in the industry. Furthermore, the researchers examined 43 actual case projects (a case study) executed with the standardization strategy to evaluate the industry's status in terms of the levels of advantage achievement and disadvantage incurrence.FindingsThe results of this survey show that design once, reuse multiple times and design and procurement in advance are the most impactful benefits. Similarly, susceptible to changes in the market conditions is one of the top trade-offs that can be incurred in capital projects when implementing standardization. The results also highlight that design once, reuse multiple times is one of the most achieved benefits in standardized capital projects today, while cost of establishing the design standard is the most incurred trade-off.Originality/valueThis study provides important insight into how standardization strategy can be advantageous while also enriching the literature about pitfalls expected from standardization. Moreover, this study's results will help the industrial sector achieve higher levels of design standardization by providing a better understanding of the benefits and trade-offs of design standardization.

Background: The number of postgraduate students in Cardiac surgical discipline is increasing day by day with incremental proportion are measurably suffering from the unnecessary lingering of the present course curriculum. The primary objective of this study was to find out the last 5 years’ of results of Masters in Surgery course under the University of Dhaka from a student room survey. A secondary objective was to find out positive changes that could show us the way of a step toward up-gradation. Methods: It is a retrospective analysis of all examination results of Cardio-vascular & Thoracic Surgery published since January 2008 to January 2013 from the University of Dhaka with in depth interview of 11 participants. Results: 85.24% students failed to pass part-I of Masters in Surgery for Cardio-vascular & Thoracic Surgery course while, 82.18% in part-II and 71.28% failed to pass the final part. Average 2.51 attempts needed to complete each part of the designed course resulted into lingering of course duration for 42.18 months/student. In the thoracic surgery discipline the number of students alarmingly reduced up to 0% in the recent academic sessions. Conclusions: Masters in Surgery is resulting in unnecessary prolongation of the course. We should step forward to meet the next generation challenge.

Insight Into

The genre of annotated verse represents an under-explored form of transporting romanticism. In annotated, locodescriptive poems like those in Anna Seward's Llangollen Vale, readers are invited to read not only the spatiality of the landscapes depicted in the verse but also the landscape of the page itself. Seward's poems, with their focus on understanding geographical, political, and historical spaces both real and imaginary, provide geocritical insight into poetic productions of the early Romantic era. Likewise, geocriticism offers a fresh and useful – even necessary – analytic approach to such poems. I adopt Anna Seward as a case study in annotated verse and argue that attending to the materiality and paratextuality of her work allows us to access the complexities of her poetry and prose as well as her position within the wider framework of transporting Romanticism.

Abstract: Presented from an ArtScience practitioner's perspective, this paper provides an overview of Svenja Kratz's experience working as an artist within the area of cell and tissue culture at QUT's Institute of Health and Biomedical Innovation (IHBI). Using The Absence of Alice, a multi-medium exhibition based on the experience of culturing cells, as a case study, the paper gives insight into the artist's approach to working across art and science and how ideas, processes, and languages from each discipline can intermesh and extend the possibilities of each system. The paper also provides an overview of her most recent artwork, The Human Skin Equivalent/Experience Project, which involves the creation of personal jewellery items incorporating human skin equivalent models grown from the artist's skin and participant cells. Referencing this project, and other contemporary bioart works, the value of ArtScience is discussed, focusing in particular on the way in which cross-art-science projects enable an alternative voice to enter into scientific dialogues and have the potential to yield outcomes valuable to both disciplines.
