This paper presents the comparative study of design efficiency of two different brands of products, performing the same function using the Design for Manufacturing and Assembly (DFMA) method. The study aims to compare the products on the relative design efficiency. The DFMA method was used as it is a well-established technique for improving the efficiency of the product leading to minimizing production costs. It also shortens product development time by reducing the number of components in a product. The study used two different brands of dry iron as a case study. The result shows that the percentage of the design efficiency of dry iron A is 8.82%, whereas it is 10.34% of dry iron B. Thus, the dry iron B is much better as compared to A in term of its assembly operation and design efficiency. Therefore, the dry iron B is greener than dry iron A. Furthermore, a redesign of dry iron B was proposed and analyzed for the internal validation. The DFMA analysis result shows that the percentage of design efficiency of a new conceptual design of dry iron B increased to 18.08%. The application of the DFMA method to enhance the eco-friendliness of a product has been proven to be highly useful in design work.

Digital Components

Abstract The recent digital-born electronic literature has heterogeneous components such as kinetic texts, kinetic images, graphical designs, sounds, and videos. These digital components are embedded with the main text as the paratext of print and digital works such as preface, author’s name, illustrations, and title. However, the comparative study between paratext and embedded paratext of electronic literature shows the different strategic patterns and functions of these entities. We discuss the conceptual framework of illuminant devices of paratexts and propose a new term technoeikon to recognize the functions of embedded literary artifact in digital literary works. We examine the critical construction of new term technoeikon which has a unique characteristic that makes electronic literary works different from print literature. This essay reviews the cyclical process of technoeikon from the historical perspective of pre-print culture and print culture and acknowledges technoeikon as inherited from our tradition. Due to digital contrivances, technoeikon takes a new expression as performing in digital ecology which is different from our traditional analog. This article presents a case study on Andy Campbell's (2007b) Dim O'Gauble. Also, Campbell responds to the interpretation of new term technoeikon in the fourth section of the essay.

In the present study, a specific and simple second law based exergoeconomic model with instant access to the production costs is introduced. The model is generalized for a case study of Shiraz solar thermal power plant with parabolic collectors for nominal power supply of 500 kW. Its applications include the evaluation of utility costs such as products or supplies of production plant, the energy costs between process operations of an energy converter such as production of an industry. Also attempt is made to minimize objective function including investment cost of the equipments and cost of exergy destruction for finding optimum operating condition for such plant.

Capital Intensive

Wafer fabrication is a capital intensive industry. A 12-inch wafer fabrication plant needs a typical investment of US$ 3 billion, and the equipment cost constitutes about two-thirds to three-quarters of the total production costs. Therefore, capacity planning is crucial to the investment and performance of wafer fabrication plants. Several formulae are presented to calculate the required number of machines with sequential, parallel, and batch processing characteristics, respectively. An AutoSched AP simulation model using data from real foundry fabrication plants is used in a case study to evaluate the performance of the proposed formulae. Simulation results indicate that the proposed formulae can quickly and accurately calculate the required number of cluster tools leading to the required monthly output rate.

The Comparative Study

This article considers the role of generalization in comparative case studies, using as exemplars the contributions to this special issue on climate change politics. As a research practice, generalization is a logical argument for extending one’s claims beyond the data, positing a connection between events that were studied and those that were not. No methodological tradition is exempt from the requirement to demonstrate a compelling logic of generalization. The article presents a taxonomy of the logics of generalization underlying diverse research methodologies, which often go unstated and unexamined. I introduce the concept of resonance groups, which provide a causeway for cross-system generalization from single case studies. Overall the results suggest that in the comparative study of complex political systems, case study research is, ceteris paribus, on par with large-N research with respect to generalizability.

Web usage mining is used to find out fascinating consumer navigation patterns which can be applied to a lot of real-world problems, such as enriching websites or pages, generating newly topic or product recommendations and consumer behavior studies, etc. In this paper, an attempt has been made to provide a taxonomical classification of web usage mining applications with two levels of hierarchy. Further, the ontology for various categories of the web usage mining applications has been developed and to prove the completeness of proposed taxonomy, a rigorous case study has been performed. The comparative study with other existing classifications of web usage mining applications has also been performed.

Chicken broiler is the main commodities  and largest in Indonesia, where Kampar district into production centre in the province of Riau. According to the company's partners, breeder who partnered with the pattern contract farming hasn't been able to combine the use of livestock production facilities as well as labor. This resulted in not maximizing the profits obtained by breeders. The purpose of the research was to analyze broiler chicken farming and analyze the efficiency of broiler chicken production. Analytical method used is the analysis method of broiler chicken flocks and the DEA method. Respondents needed is 40 farmers who have partnered with the contract farming pattern. The results showed that the production costs of Rp.180.031.229 /period, revenue Rp.203.573.865/period, so that the profit amounting to Rp 23.542.636/period with R/C ratio of 1.13. The results of the efficiency analysis show that inefficient farmers are more numerous than those who have been efficient. It showed breeders hasn't been able to use the minimum input produce output that is optimal and maximum profit.
