    A ROOT/IO Based Software Framework for CMS

    Full text link
    The implementation of persistency in the Compact Muon Solenoid (CMS) Software Framework uses the core I/O functionality of ROOT. We will discuss the current ROOT/IO implementation, its evolution from the prior Objectivity/DB implementation, and the plans and ongoing work for the conversion to "POOL", provided by the LHC Computing Grid (LCG) persistency project

    Reynolds v. Tufenkjian, 136 Nev. Adv. Op. 19 (Apr. 9, 2020)

    Full text link
    The Court considered whether a party who purchased a judgment debtor’s rights of action could motion the Court to substitute themselves in as the real party in interest and dismiss the appeal. The Court held that only “things in action” that are otherwise assignable may be subject to execution to satisfy a judgment. The Court concluded that tort claims for personal injury—including fraud/intentional misrepresentation and elder exploitation—are generally not assignable. The Court further concluded that tort claims for injury to property and contract-based claims, unless the claims are personal in nature, are generally assignable. Therefore, the Court granted the respondents’ motion in part and the appeal was dismissed in part

    A distributed file service based on optimistic concurrency control

    The design of a layered file service for the Amoeba Distributed System is discussed, on top of which various applications can easily be intplemented. The bottom layer is formed by the Amoeba Block Services, responsible for implementing stable storage and repficated, highly available disk blocks. The next layer is formed by the Amoeba File Service which provides version management and concurrency control for tree-structured files. On top of this layer, the appficafions, ranging from databases to source code control systems, determine the structure of the file trees and provide an interface to the users

    An overview of the Amoeba distributed operating system

    As hardware prices continue to drop rapidly, building large computer systems by interconnecting substantial numbers of microcomputers becomes increasingly attractive. Many techniques for interconnecting the hardware, such as Ethernet [Metcalfe and Boggs, 1976], ring nets [Farber and Larson, 1972], packet switching, and shared memory are well understood, but the corresponding software techniques are poorly understood. The design of general purpose distributed operating systems is one of the key research issues for the 1980s

    Design fictions

    This studio provides participants with an opportunity to engage in a hands-on exploration of the use of "design fictions" as a strategy for producing physical artifacts. The idea of design fictions blurs the boundaries between traditional design practices and narrative explorations of potential futures. If the goal of design is to devise courses of action aimed at changing existing situations into preferred ones, then the goal of design fiction is to use speculations, metaphors, and explorations of desired futurities to explicate and inform material design practices. Participants will have a chance to discuss these ideas, as well as to design and build their own "diegetic prototypes" out of materials sourced from local antique shops, thrift stores, and other nearby sources of inspiration. Through this hands-on exploration of the constraints and affordances of fictional scenarios and scavenged materials, we hope to collectively explore a compelling new design space for tangibles

    Steampunk as Design Fiction

    Get PDF
    in this paper we look at the Steampunk movement and consider its relevance as a design strategy for HCI and interaction design. Based on a study of online practices of Steampunk, we consider how, as a design fiction, Steampunk provides an explicit model for how to physically realize an ideological and imagined world through design practice. We contend that the practices of DIY and appropriation that are evident in Steampunk design provide a useful set of design strategies and implications for HCI

    Partial reflections of radio waves from the lower ionosphere

    The addition of phase difference measurements to partial reflection experiments is discussed, and some advantages of measuring electron density this way are pointed out. The additional information obtained reduces the requirement for an accurate predetermination of collision frequency. Calculations are also made to estimate the errors expected in partial-reflection experiments due to the assumption of Fresnel reflection and to the neglect of coupling between modes. In both cases, the errors are found to be of the same order as known errors in the measurements due to current instrumental limitations

    Multi-brand hospitality operations branding strategies

    Full text link
    The purpose of this professional paper is to identify the optimal brand architecture for MGM MIRAGE’s Project CityCenter through synthesis of a review of branding strategies throughout the hospitality industry and a review of Project CityCenter’s goals. As Project CityCenter represents such a massive undertaking from both a financial and marketing perspective, a review of strategies external to MGM MIRAGE is critical; this paper endeavors to highlight branding strategies for potential adoption at Project CityCenter. The project’s significance is affirmed by Terri Lanni, Chairman and CEO of MGM MIRAGE, “Project CityCenter confirms a cultural and lifestyle revival of city living, reaffirms the growing sophistication and maturity of Las Vegas and sets a benchmark for new growth and exciting new experiences as the city moves into the next 100 years” (World Class Architects, 2005)
