Title: Performance Evaluation of Dynamic Particle SwarPerformance Swarm Optimization Author: Ms. Hemlata S. Urade; Prof. Rahila Patel Abstract: In this paper the concept of dynamic particle swarm optimization is introduced. The dynamic PSO is different from the existing PSO’s and some local version of PSO in terms of swarm size and topology. Experiment conducted for benchmark functions of single objective optimization problem, which shows the better performance rather the basic PSO. The paper also contains the comparative analysis for Simple PSO and Dynamic PSO which shows the better result for dynamic PSO rather than simple PSO. Description: Optimization has been an active area of research for several decades. As many real-world optimization problems become increasingly complex, better optimization algorithms are always needed. Unconstrained optimization problems can be formulated as a D-dimensional minimization problem as follows: Min f (x) x=[x1+x2+……..xD] where D is the number of the parameters to be optimized. subjected to: Gi(x) <=0, i=1…q Hj(x) =0, j=q+1,……m Xε [Xmin, Xmax]D, q is the number of inequality constraints and m-q is the number of equality constraints. The particle swarm optimizer (PSO) is a relatively new technique. Particle swarm optimizer (PSO), introduced by Kennedy and Eberhart in 1995, [1] emulates flocking behavior of birds to solve the optimization problems.

Effectively Visualizing Library Data

Title: Effectively Visualizing Library Data Author: Phetteplace, Eric Abstract: As libraries collect more and more data, it is worth taking some time to analyze the data we collect and effectively present it. This article details how to use visualization to investigate trends and make compelling arguments with data.

Other People's Money: Adapting Entrepreneurial Techniques to Build Capital in Challenging Economic Times

Title: Other People's Money: Adapting Entrepreneurial Techniques to Build Capital in Challenging Economic Times Author: Farrell, Robert Abstract: Drawing on the “predator” model of ntrepreneurship put forward by Villette and Vuillermot in their 2009 book “From Predators to Icons,” this article argues that challenging economic times reveal that self-funded, collaborative information literacy models have in many cases unsustainably overstretched staff and budgets. In such circumstances, it is necessary for librarians to shift to an entrepreneurial approach that seeks profitable opportunities funded by parties other than the library in order to build capital for current and future instructional services. Following Villette and Vuillermot, the article seeks to refute a cultural myth that sees the entrepreneur as someone who is first and foremost a “do-gooder” or marketer of helpful products, and it also advocates that librarians adopt a view of the entrepreneur as one who preys on unexploited, lowcost/high-profit opportunities to leverage “other people’s money” to build capital for later innovation. The article considers the economics of information literacy and library instruction programs, provides historical context for what has come to be known as the “collaborative imperative,” points to the economic shortsightedness of many collaborative and “embedded librarian” partnerships, and details six examples from information literacy programs that model successful entrepreneurship of the sort argued for.

Design and Development of Multimedia Based User Education Program: The Advantages of YouTube

Tue, 23 Apr 2013 00:00:00 GMT

Title: Design and Development of Multimedia Based User Education Program: The Advantages of YouTube Author: Ram, Shri; Paliwal, Nitin Abstract: User education is one of the essential activities of the library to optimize the use of library services. This paper discusses the use of multimedia based videos for the promotion of library services and activities with the help of emerging trends and technologies and the power of Web 2.0 especially YouTube. Through this paper, it is tried to demonstrate the procedural aspects of promoting user education through developing multimedia based user education program and utilizing the services of YouTube as media of marketing and communication at Jaypee University of Information Technology, Solan, Himachal Pradesh, India.
