We study the asymptotic behavior of viscosity solutions uGλ Hamilton-Jacobi (HJ) equation λu(x)+G(x,u′)=c(G) in Ras positive discount factor λ tends to 0, where G(x,p):=H(x,p)−V(x) is perturbation a Hamiltonian H∈ C(R×R), Z–periodic space variable and convex coercive momentum, by compactly supported potential V∈Cc(R). The constant c(G) appearing above defined as infimum values a∈R for which HJ ...

In this article, we consider the main challenges that impede us from realizing the great promise of computersupported cooperative work (CSCW). First, we discuss some of the key features that CSCW must provide in order to succeed with users. We follow this with a picture of the current state of the practice among CSCW users, and then we examine some technologies that hold promise for future appl...

This paper approaches heterogeneity and heterogeneous technology as assets, rather than limitations, in the development of computer supported cooperative work. We demonstrate how heterogeneous technologies sustain teachers’ and students’ school work by presenting four different prototypes (the HyConExplorer, the eCell, the iGameFloor and the eBag) that complement one another because they offer ...

Computer Supported Cooperative Work (CSCW) research is the discipline that explores how to utilize computing and networking technologies to facilitate cooperation and collaboration among people. A variety of research has been conducted on CSCW architecture. However, how to ensure CSCW system effectiveness and efficiency on supporting collaboration remains a challenge. In this paper we present a...

This paper introduces Open Planning Process Panels (O-p3). These panels are based on explicit models of the planning process and axe used to coordinate the development and evaluation of multiple courses of action. We describe the generic ideas behind O-P3 technology, a general methodology for building O-P3 interfaces and two applications based on O-P3 technology the Air Campaign Planning Proces...

Single-atom catalysts on supported silicomolybdic acid for CO 2 electroreduction.

The nuclei of active comets emit molecules anisotropically from discrete vents. As the nucleus rotates, we expect to observe periodic variability in the molecular emission line profiles, which can be studied through mm/submm spectroscopy. Using this technique Based on observations carried out with the IRAM 30-m, JCMT 15-m, and CSO 10.4-m telescopes. IRAM is supported by INSU/CNRS (France), MPG ...

An efficient synthesis of chromenylphenylpropanone derivatives as warfarine-like analogues was developed by the Michael addition of 4-hydroxycoumarin to α,β-unsaturated compounds in the presence of polyvinylpolypyrrolidone supported antimony(III) chloride (PVPP-SbCl3) as a new polymeric Lewis acid catalyst in chloroform at reflux conditions without formation of 2,4-...

We examine oscillation behavior of normal logic programs. Both the Gelfond-Lifschitz operator and the TP operator are used to update Herbrand interpretations, and any interpretation finally reaches in an oscillator. It has been shown that the supported model semantics of normal logic programs can characterize point attractors of Boolean networks. We here newly define supported classes of normal...
