Computer aided engineering (CAE) is a systematic approach to develop a better product/application with maximum possible options and minimum transition time. This paper presents a comprehensive feasibility analysis of various CAE techniques for evaluation and optimization of power electronic converters and systems. Different CAE methods for analysis, design, and performance improvement are classified. In addition, their advantages compared to the conventional workbench experimental methods are explained in detail and through examples.

The paper introduces a model for evaluating and prioritizing mobile quality attributes and refactoring techniques through the examination of their effectiveness during the mobile application development process. The astonishing evolution of software and hardware has increased the demand for techniques and best practices to overcome the many challenges related to mobile devices, such as those concerning device storage, network bandwidth, and energy consumption. A number of studies have investigated the influence of refactoring, leading to the enhancement of mobile applications and the overcoming of code issues as well as hardware issues. Furthermore, rapid and continuous mobile developments make it necessary for teams to apply effective techniques to produce reliable mobile applications and reduce time to market. Thus, we investigated the influence of various refactoring techniques on mobile applications to understand their effectiveness in terms of quality attributes. First, we extracted the most important mobile refactoring techniques and a set of quality attributes from the literature. Then, mobile application developers from nine mobile application teams were recruited to evaluate and prioritize these quality attributes and refactoring techniques for their projects. A prioritization-based model is examined that integrates the lightweight multi-criteria decision making method, called the best-worst method, with the process of refactoring within mobile applications. The results prove the applicability and suitability of adopting the model for the mobile development process in order to expedite application production while using well-defined procedures to select the best refactoring techniques. Finally, a variety of quality attributes are shown to be influenced by the adoption of various refactoring techniques.

Immobilized enzymes have become the subject of considerable interest due to their excellent functional properties such as reusability, cost-effectiveness, and optimality during the past decades. Enzyme immobilization technology is not only used in industrial processes, but also a component technology of products for medical diagnostics, therapy, food industry, bio energy, and biomaterial detection. In this review, new methods for enzyme immobilization are introduced, and the advantages and disadvantages of a variety of techniques in enzyme immobilization will be also discussed.

This is an extended paper, focusing on the cost management for the organizations dealing with the crucial issues of security systems. Information Technology (IT) is an important and irreplaceable need of society and all working sector's success depends on IT to a greater extent; therefore maintaining security features is one of the most important aspects of IT. When security in the IT sector is discussed, Patch Management (P.Mgnt) has to be taken under account. P. Mgnt includes many concerns and areas to be described for IT security such as methods and problems in updating patch, methods of reducing security risks with P.Mgnt, methods of achieving economies of scale by controlling the operational costs and taking decisions in investing as and when necessary. This paper presents a general definition of Patch management, its benefits and management of working cost through theoretical models, also the paper gives methods of feeding techniques for microstrip patch antenna MPA, showing the contracting and non contracting methods.

We usually use two techniques(influence function and local influence) for detecting outliers. But, we cannot use these difficult techniques in elementary industrial statistics course for college students. We can use some simple graphical methods(box plot, dandelion seed plot, influence graph and cumulative deletion plot) for univariate and bivariate outlier detection and outlier effect in elementary industrial statistics course for college students.

In order to compare analytical conditions for measuring PAHs(polycyclic aromatic hydrocarbons) in ambient air, a series of experiment were conducted using three different types of extraction methods that include:(1) accelerated solvent extraction (ASE), (2) soxhlet, and (3) sonification methods. Efficiency and relevant analytixal parameters for each of these methods were examined on five different types of solvents that include:(1) 10% diethyl ether in n-hexane(v/v), (2) dichloromethane, (3)cyclohexane.(4) toluene, and (5) Benzene: ethanol (4:1). Comparison of extraction efficiency for various combinations between methods and solvents was made through an application of both internal and external standard calibration techniques. The extraction efficiency tests, when checked using both internal and external standards, allowed us to derive meaningful comparison among different techniques and among solvents.

The most important factors for a product to survive in the market are cost and quality. In recent years, quality proceeds to cost. There are many techniques of use to improve the quality of a product. One of the techniques is applying statistical methods (especially Taguchi method) to real operational conditions for a continuous manufacturing process in P company. There are 91 factors to control in the process. So, we predetermined 7 main effect factors and 6 interactive effect factors by statistical methods and advices of engineers. With these 13 factors, we determined the optimal level of operations for the process.

Many strengthening methods are introduced and used to rehabilitate existing structures. However, both theoretical background and application techniques are not. One of the most popular methods is bonded plate method using either steel plate or carbon plate. For bonded plate method, bonding at the end of the plate is the most important properties. In this study, a method to reduce the stress distribution at the end of the bonded plate is found and tested. The results showed that the proposed end anchoring method is effective.

Acupuncture and moxibustion of theory had begun in the "Nei-Jing" and "Nan-Jing". But definite acupuncture needling techniques had been investigated after Jin and Yuan Dynasty. After Ming Dynasty, much more scholars had studied about definite acupuncture needling techniques. So various techniques and theorys about how to select and operate needling points appeared in print. "Zi-Wu-Liu-Zhu-Zhen-Jing", "Zhen-Jing-Zhi-Nan", "Shen-Ying-Jing", "Zhen-Jiu-Da-Quan" and so forth are representative books. But these books include mutually different techniques, so then scholars would be thrown into confusion. So I have analysed acupuncture and moxibustion of theory into Ki(vital energy)-blood's circulation, disease region, time, sex, restorative and restrictive techniques. As a result, I have known that every restorative and restrictive techniques and theories are connected with Ki(vital energy)-blood's circulation and practical application methods are decided by sex, time, disease region, pathogenic energy.

Fine art production methods are frequently incorporated into animation production. The Printing Expression method is often employed among fine art production. There are three main techniques in Printing Expression: Silk Screen, Woodcut and Etching. Animations that use Silk Screen and Woodcut techniques are quite common. However, it is rare to find Etching techniques in animations. So with that being said, I would like to introduce etching animation through the work of Piotr Dumala; the well known Ink Etched film director. Also, I analyzed the characters: movement, unique texture and sensuous feeling; that only mezzotinted Etched-Animation expression technique can show. If we can expand methods on how to show our imagination through etching techniques, it can allow many directors to produce etched animation films in which they can express their imagination.
