  • Physical theories allow us to make predictions: given a complete description of a physical system, we can predict the outcome of some measurements. This problem of predicting the result of measurements is called the modelization problem, the simulation problem, or the forward problem. The inverse problem consists of using the actual result of some measurements to infer the values of the parameters that characterize the system. While the forward problemhas (in deterministic physics) a unique solution, the inverse problem does not.

  • Backtracking = depth-first search with one variable assigned per node; variable ordering and value selection heuristics help significantly; forward checking prevents assignments that guarantee later failure; constraint propagation (e.g., arc consistency) does additional work to constrain values and detect inconsistencies; the CSPs representation allows analysis of problem structure.

  • Although mobile devices, cellular phones, Personal Digital Assistants (PDAs) and other handheld devices have hardware constraints such as small screen, small storage, low CPU speed, and low resolution, their popularity has been enormously increasing. This is enhancing the opportunities for researchers to overcome those open problems caused of small size hardware constraints. However, still the biggest difficulty is that these devices are too difficult to load today’s visual information because most current information is based on a large visual documentation.

  • The inclusion of Business Angels in the range of ‘informal’ (as opposed to ‘institutional’) investors provides us an indication that there are potential difficulties in measuring the size of the Business Angel community. Mason and Harrison identify two main problems, identification and definition. Regarding the former, in his seminal work on Business Angels, William Wetzel (1983) notes that the total population of Business Angels is unknown and probably unknowable on account of their invisibility, desire for anonymity, and the undocumented nature of their investing.

  • Abstract.The proliferation of new modes of communication and collaboration has resulted in an explosion of digital information. To turn this challenge into an opportunity, the IT industry will have to develop novel ways to acquire, store, process, and deliver information to customers - wherever, however, and whenever they need it. An ”Intelligent IT Infrastructure,” which can deliver extremely high performance, adaptability and security - will be the backbone of these develop ments.

  • This study, given its Bayesian approach, is related to the recent article by Baks, Metrick, and Wachter (2001), who estimate funds' alphas using informative prior beliefs about alpha. They investigate the degree to which informative priors can preclude an investor from infer- ring that at least one actively managed fund has a positive alpha. This inference relates to an investment problem of a mutual fund investor who can also earn the hypothetical costless returns on the benchmark indexes.

  • The 74th ranked problem in the survey is “Undocumented Workers,” a problem first introduced in 2008. Seven percent find it a critical problem compared to 55 percent who do not. While the issue draws substantial media attention and passionate view on both sides, the number of small-business owners concerned by the business implications of undocumented workers is minimal. “Access to High-Speed Internet” ranks 73rd and is critical for 7 percent of small-business owners.

  • With the proliferation of Web and multimedia services, and virtual private networks (VPNs) connecting corporate sites, more versatile Internet routing protocols have become critical. Current Internet packet forwarding is based on the destination address. Simple routing algorithms that determine forwarding paths based on the minimum number of hops or delay to a specified destination are no longer sufficient. The need to support diverse traffic types and applications with quality demands (see Figure 1) imposes new requirements on routing in the (now commercial) Internet.

  • MAXIMUM PRINCIPLES FOR A FAMILY OF NONLOCAL BOUNDARY VALUE PROBLEMS PAUL W. ELOE Received 21 October 2003 and in revised form 16 February 2004 We study a family of three-point nonlocal boundary value problems (BVPs) for an nthorder linear forward difference equation. In particular, we obtain a maximum principle and determine sign properties of a corresponding Green function. Of interest, we show that the methods used for two-point disconjugacy or right-disfocality results apply to this family of three-point BVPs. 1.

  • The international consequences of zero-interest-rate policies are also negative. With interbank markets in the U.S. and Europe congested, forward foreign exchange markets become more difficult to organize. Without forward cover, exporters and importers find it more difficult to secure normal letters of credit. In the financial panic of 2008, foreign trade imploded much more than domestic trade. In addition, the Fed’s zero interest rate strategy inevitably weakens the dollar in the foreign exchanges.

  • Though systems still exist based on these models, they are not nearly as common as they once were. A directory service like ActiveDirectory orOpenLDAP is where you are most likely to engage in new hierarchical development. Another model—the object model—is slowly coming into favor for limited problem domains. As its name implies, it is a data model based on object-oriented concepts. Because Java is an object-oriented programming language, it actually maps best to the object model.
