Structural Analysis Of Shape-Morphing Aircraft Slat By Using Finite Element Analysis

The changing of the wing shapes on an aircraft always amazes many people especially those in the flights. The field of shape morphing aircraft has attracted the attention of many research groups during the past century. Although many interesting concepts have been synthesized, only a handful involves the shape morphing slat for aircraft wing. The aerodynamic pressure of the morphing slat structure could lead to failure or structural damage, probably stemming from the basic design or the result of the failure seen in the material used for the structure's manufacturing. The purpose of this research is to analyze the new generation of aircraft morphing slat, by utilizing a Finite Element (FE) model as a design tool to assess the structural integrity of structure of the new morphing slat. Another aim is to investigate a material deemed suitable for making the morphing slat that can result in less deformation and stresses. In this study, structural analyses were carried out by using ANSYS WORKBENCH on the morphing slat geometry after creating it in CATIA V5. In a structural analysis, the modeling used three different materials, namely, Al6065-T6, AA7075-T651, and GFRP. The structure of morphing slat is subject to maximum aerodynamic pressure in two flight phases that include taking-off and landing which was found by using Computational-Fluid Dynamics (CFD) analysis from earlier work. By conducting the structural analysis, one can examine the reliability of the rigid segments and structure of morphing slat under the applied aerodynamic load, which is necessary for the selection of the material for the morphing slat design. The results of static structural analysis showed that the AA7075-T651material is the most suitable material that can be used for morphing slats because it has the least deformation and strain after comparing it with Al6065-T6 and GFRP. Hence, AA 7075-T651 can give the structure of morphing slat more strength over the other two materials

Budgetary control system for University of Karbala Iraq based on adaptive budgetary control framework

Every organisation doing exceedingly well relies heavily on budgets, and in essence budgetary control measures to improve performance through adequate resource allocation. Budget and Budgetary control, both at management and operational levels. Following the same trends, University of Karbala Iraq needs to implement a budgetary control system as since 2002, KU is one of the best university within Iraq and also in the Arabic regional level with approximately of 12,000 students studying in 16 different faculties which are as follows: Medicine Faculty, Veterinary Medicine, Pharmacy, Faculty of Engineering, Faculty of Applied Medical Sciences, Education, Management and Economics, Faculty of Law, Faculty of Science, Faculty of Agriculture, Faculty of Islamic Sciences, religious tourism, Faculty of Education, Humanities, Faculty of Education Pure Sciences and Nursing. Currently, there is no budgetary control system has been implemented at university of Karbala, Iraq. In the aspect of university of Karbala Iraq, budgetary control system has been designed to mitigate current needs which have been integrated to the budget applicants, budget approval from ministry and budget allocation by the university Finance Department. This study identifies the link between budget and budgetary control by studying several budgetary control frameworks and then finally proposed a new adaptive budgetary control framework followed to budgetary control system prototype development. The system has been evaluated by the questionnaire with 10 respondents from University of Karbala Iraq

Deficits and inflation; Are monetary and financial institutions worthy to consider or not?

AbstractInstitutions are important to analyze the relationship between deficits and inflation. This study examines whether deficits are inflationary or not in the presence of dependent central bank and fragile financial markets. A panel dataset has been used for eleven Asian countries from 1981 to 2010. Estimation results from system GMM show that deficits are inflationary for selected sample, while inflationary pressure of budget deficits is particularly stronger when financial markets are not fully developed and central banks are not free to follow their goals and objectives

Portfolio Management And Disposition Effect Empirical Evidence From Pakistan.

Kahneman and Tversky’s approach to preference under uncertainty is aversion to loss realization. This paper is an attempt to highlight this phenomenon with a unique approach. In order to beat the market fund managers are required to manage their portfolio at regular intervals. The tendency to sell the winners too early and ride the losers for long “disposition effect” can affect the Management decision of fund managers. This paper investigates the mediating role of disposition effect between mental accounting, aversion to regret, self control and portfolio Management. For this purpose we use the extended version of Shefrin and Statman framework and include Dyl’s tax consideration. In order to provide empirical evidence survey has been conducted from mutual fund managers.  CFA and Cronbach’s alpha is used to test the reliability of the instrument. AMOS tool is used to test the structure equation model for disposition effect and portfolio Management. Results confirmed that disposition effect plays significant role of mediator between mental accounting, aversion to regret, self control and portfolio Management. However tax consideration has direct loading on forward Management. It means that disposition effect plays significant role in decisions of fund managers; however investors are aware of tax consideration

Use of Financial Instruments and Interaction with Islamic Financial Law

This research provide an analysis of how financial instruments are used in markets, and to what extent they are related to Islamic financial law. Islamic law prohibits usury, uncertainty, and those transactions that involve ambiguity. Conventional finance on the other hand is debt based and involves a lot of risk. We used structured interview questionnaire, and experts from the field of conventional and Islamic finance were interviewed. Results of structure interview reveal that many things are common between Islamic and conventional finance such as rent for services in case of both conventional and Islamic lease. The Murabaha is somewhat similar to asset backed risky loan. The features of Mudaraba are closer to European option such that profits from Mudarabah offset call price. In addition the deposits are collected under both systems. This research also found that best financial instrument for increasing value of a firm is equity financing, while debt financing is not a good choice, because the later increases risk and decreases value of a firm. Swaps and forwards are used for hedging risks and saving the future. It is concluded that most of the conventional instruments are not prohibited, and they intersect at various points with Islamic financial law. The gap of two systems can be reduced by taking number of steps such as transferring ownership of a leased asset after first installments. Furthermore the gap can also be reduced if shares are offered for purchase of an asset at beginning, and when that asset begins to produce cash flows, then distributing profits equally, but the bank or organization providing services will be provided service charges.

Difference in the Population Size between Rural and Urban Areas of Pakistan

The purpose of present study is to explore the trend of difference in population size and growth rate of the two sectors of Pakistan i.e. rural and urban over a period of 57 years (from 1960 to 2017). It is important to know this trend for resources allocation and also to get an insight into related issues in future. The data has been obtained from secondary source of publically available site of World Bank. Results demonstrate a progressive increase in the population size of both the sectors. However, the pace of increase in population of rural sector is not only faster than that of urban but also it shows a much higher rate of increase after 1980. But in case of population growth rate it is urban sector that leads. Throughout the span of 57 years, for urban area the growth rate has varied from 4.6% to 3.1%. On the other hand, for rural areas, it ranges from 3.1% to 1.2%. Results are discussed along with their probable reason

The challenges to women's entrepreneurial involvement in the hospitality industry

Entrepreneurship is one of the growing trends, and studies are focusing on it generally. However, this study is mainly focused on women’s entrepreneurship. This study intends to measure the impact of work-family interference, socio-cultural support, access to finance entrepreneurial skills, and legal constraints on women’s entrepreneurial involvement through the mediation of self-leadership in the hospitality and tourism sector. This study has chosen a quantitative approach, collecting data through surveys. The snowball sampling method was used for data collection from women of Pakistan, and data was analyzed through the PLS-SEM method. The result of the present study affirms that work-family interference, social and cultural support, and entrepreneurial skills are significantly associated with women’s entrepreneurial involvement other than access to finance and legal constraints. Moreover, self-leadership significantly mediates between (work-family interference, socio-cultural support, and access to finance) and women’s entrepreneurial involvement except for entrepreneurial skills and legal constraints. The present study’s findings affirm that formal or informal institutions influence women’s entrepreneurial involvement. This study may help women entrepreneurs understand the factors and policymakers to make policies for women entrepreneurs in the hospitality sector

Big data and predictive analytics in healthcare in Bangladesh: regulatory challenges

Big data analytics and artificial intelligence are revolutionizing the global healthcare industry. As the world accumulates unfathomable volumes of data and health technology grows more and more critical to the advancement of medicine, policymakers and regulators are faced with tough challenges around data security and data privacy. This paper reviews existing regulatory frameworks for artificial intelligence-based medical devices and health data privacy in Bangladesh. The study is legal research employing a comparative approach where data is collected from primary and secondary legal materials and filtered based on policies relating to medical data privacy and medical device regulation of Bangladesh. Such policies are then compared with benchmark policies of the European Union and the USA to test the adequacy of the present regulatory framework of Bangladesh and identify the gaps in the current regulation. The study highlights the gaps in policy and regulation in Bangladesh that are hampering the widespread adoption of big data analytics and artificial intelligence in the industry. Despite the vast benefits that big data would bring to Bangladesh's healthcare industry, it lacks the proper data governance and legal framework necessary to gain consumer trust and move forward. Policymakers and regulators must work collaboratively with clinicians, patients and industry to adopt a new regulatory framework that harnesses the potential of big data but ensures adequate privacy and security of personal data. The article opens valuable insight to regulators, academicians, researchers and legal practitioners regarding the present regulatory loopholes in Bangladesh involving exploiting the promise of big data in the medical field. The study concludes with the recommendation for future research into the area of privacy as it relates to artificial intelligence-based medical devices should consult the patients' perspective by employing quantitative analysis research methodology. © 2021 The Author(s
