It benefits from a strategic service-oriented thinking and standardizationin order to improve quality and increase profitability. This paper provides a brief introduction to service management

Forgery is the criminal act that provides misleading information about a product or service. It is the process of making, adapting, or imitating documents or objects with the intent to deceive. Digital forgery (or digital tampering) is the process of manipulating documents or images for the intent of financial, social or political gain. This paper provides a brief introduction to the digital forgery.

E-science refers to the type of scientific research that uses large-scale computing infrastructure to process very large amount of data. It is an interdisciplinary branch of science that explores and implements information technology platforms, which includecomputer networks, computer information technology, telecommunication, and computational methods. This paper provides a brief introduction to e-science.

In this study, a new forty-two point’s second order rotatable design is constructed using transformations of some trigonometric functions. This design permits a response surface to be fitted easily and provides spherical information contours besides the economic use of scarce resources in relevant production processes.

For college students, adjustment required in various dimensions, which degree and type is varied with students depending on background, experience and prior schooling and environment of college. It’s a process of finding and adopting modes of behavior suitable to the environment. Generally emotional and social adjusted students perform better. In present study adjustment of college students have been measured and comparatively analyzed.

Z-transformation is one of the most popular tools to solve Mathematical, Physical, biological, electronic, control and signal processing systems and difference equation. The purpose of this research paper is to discuss the application of z-transformation on Gambler’s ruin in probability theory. In this paper Gambler’s ruin model in probability theory and compound interest model are discussed via z-transformation.1

Educationists are concerned about what kind of activities and things serve as efficient means and tools of learning. Research in this field shows that audio visual materials in the form of pictures, chats, maps, slides, film strips, recordings have a significant contribution to learning, reinforcing role of text books and oral instructions. Objective of present study is to draw attention of school teachers to the importance and scope of audio visual aids in the learning.

Machine learning (ML) is the scientific discipline dealing with the ways in which machines learn from experience. ML algorithmslearn a desired input-output relation from examples in order to interpret new inputs. This is important for tasks such as drugdesign, industrial process, and manufacturing, with growing applications in the chemical industry. In this paper, we provide a briefintroduction of machine learning in the chemical industry.
