    We present a numerical experimentation of the global optimization algorithm presented by Velazquez et al. (2001) applied to a nonlinear hyperboloid least squares problem. This problem arises when beta sheet residues from an allosteric enzyme are fitted onto a hyperboloid by using Newton type methods. The results show that the algorithm performs well on three test cases. An important side result of... View full abstract»

    According to Koole and Mandelbauin (2001), almost 60 to 70 percent of the total costs for operating a call center involve wage and benefit expenses for personnel. It follows that determining the optimal amount of call center agents is of great interest to call center managers. This paper addresses both the staffing of agents and the provisioning of telephone lines by introducing a revenue and pena... View full abstract»

  • A trust-region interior-point method for nonlinear programming

    Publication Year: 2005, Page(s):7 - 9

    Under mild conditions, the Jacobian associated with the Karush-Kuhn-Tucker (KKT) system of a non-convex, nonlinear program is nonsingular near an isolated solution. However, this property may not hold away from such a solution. To enhance the robustness and efficiency of the primal-dual interior-point approach, we propose a method that at each iteration solves a trust-region, least-squares problem... View full abstract»

    Collaborative capabilities are a hallmark of a new generation of networked applications. While traditional collaboration puts the computer in the foreground to help users interface through personal computing portholes, ambient collaboration reverses this paradigm by placing the machine in the background and enabling users to synergistically share a workspace with focus on mutual presence and tasks...

    In this paper, we discuss the use of specialized languages to give students experience with the basic concepts of computer science without encumbering the novice with the details of a fully-featured programming language. Using techniques developed in the area of domain-specific programming languages, we have created languages which lead directly into basic computational concepts such as abstractio...

    We developed a construction toolkit for teachers to create visual educational simulation, this work is an effort to support science and inquiry based education. Because teachers are subject matter experts in the classroom, they are excellent candidates to develop educational software that meets their own pedagogical goals. We report an evaluation of nineteen teachers creating educational simulatio... View full abstract»

    We present a numerical study for two systems of conservation laws using a spacetime discontinuous Galerkin (SDG) method with causal spacetime triangulations and the piecewise constant Galerkin basis. The SDG method is consistent with the weak formulation of conservation laws, and, in the case of strictly hyperbolic systems, also with the Lax entropy condition. Convergence of the method was shown f... View full abstract»

    Sensitivity analysis in computer science aims to improve stability in computer applications by considering uncertainty due to small perturbations in parameters. Mathematical and computational methods of sensitivity analysis are discussed. Advantages and disadvantages of both methods are addressed. A tool is developed to compute computational sensitivities. This tool was validated using three simpl... View full abstract»

  • Towards a cross-platform microbenchmark suite for evaluating hardware performance counter data

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (234 KB) | HTML iconHTML

    As useful as performance counters are, the meaning of reported aggregate event counts is sometimes questionable. Questions arise due to unanticipated processor behavior, overhead associated with the interface, the granularity of the monitored code, hardware errors, and lack of standards w.r.t. event definitions. To explore these issues, we are conducting a sequence of studies using carefully-craft... View full abstract»

    The replication of a singlecamera system is not in itself a solu-tion to large scale surveillance. A scalable solution to surveillance can be achieved through employing wireless sensor network technology where distributed sensors embedded with processors communicate communications, powerintensive processing and communications, and limited memory, DISCERN (DIStributed Camera Event Recognition Netwo...

    The goal of this research is to allow software developers and testers to become aware of which files in the next release of a large software system are likely to contain the largest numbers of faults or the highest fault densities in the next release, thereby allowing testers to focus their efforts on the most fault-prone files. This is done by developing a negative binomial regression model to he... View full abstract»

    Translations of user interfaces are an essential part of software development for the World Wide Web. Web pages are translated in three ways: by the developer as part of the normal life cycle, by the community that has a vested interest in the domain, and by machine translation. In this paper, we present an informal evaluation of the quality produced by these three approaches. We discuss the naive... View full abstract»
