The ELO system, which most chess federations use today, ranks players by the results of their games. Although simple and efficient, it overlooks relevant criteria such as the quality of the moves players actually make. To overcome these limitations, Jean-Marc Alliot of the Institut de recherche en informatique de Toulouse (IRIT -- CNRS/INP Toulouse/Université Toulouse Paul Sabatier/Université Toulouse Jean Jaurès/Université Toulouse Capitole) demonstrates a new system, published on 24 april 2017 in the International Computer Games Association Journal. Since the 1970s, the system designed by the Hungarian, Arpad Elo, has been ranking chess players according to the result of their games. The best players have the highest ranking, and the difference in ELO points between two players predicts the probability of either player winning a given game. If players perform better or worse than predicted, they either gain or lose points accordingly. This method does not take into account the quality of the moves played during a game and is therefore unable to reliably rank players who have played at different periods. Jean-Marc Alliot suggests a direct ranking of players based on the quality of their actual moves. His system computes the difference between the move actually played and the move that would have been selected by the best chess program to date, Stockfish. Running on the OSIRIM supercomputer[1], this program executes almost perfect moves. Starting with those of Wilhelm Steinitz (1836-1900), all 26,000 games played since then by chess world champions have been processed in order to create a probabilistic model for each player. For each position, the model estimates the probability of making a mistake, and the magnitude of the mistake. These models can then be used to compute the win/draw/lose probability for any given match between two players. The predictions have proven not only to be extremely close to the actual results when players have played concrete games against one another, they also fare better than those based on ELO scores. The results demonstrate that the level of chess players has been steadily increasing. The current world champion, Magnus Carlsen, tops the list, while Bobby Fischer is third. Under current conditions, this new ranking method cannot immediately replace the ELO system, which is easier to set up and implement. However, increases in computing power will make it possible to extend the new method to an ever-growing pool of players in the near future.

Post-earthquake alarm systems utilize strong-motion data to provide valuable information that enables better rapid decision making during critical and difficult immediate post-earthquake response actions. A novel robust approach for providing alarms for large distributed facilities using real-time estimation of response spectra obtained from near free-field motions is presented. The approach can be considered an enhancement on the standard seismic monitoring required for individual nuclear power plants by the Nuclear Regulatory Commission. The inherent scalability, however, affords large scale deployment for multiple facilities distributed across a vast regional area. An influential study dating back to the late 1980's identified spectral response acceleration as a key ground motion characteristic that correlates well with observed damage in structures. Thus, monitoring and reporting on exceedance of spectra-based thresholds are useful tools for assessing the potential for damage to facilities or multi-structure campuses based on input ground motions only. In fact, this type of monitoring is required for all nuclear power plants in the US and globally. Currently, the standard approach is to trigger and record an earthquake event in its entirety, perform necessary post processing (e.g., signal conditioning), compute spectral responses, check for exceedance, and issue alarms accordingly. This approach has worked well for individual plants with a small number of channels. However, it is not scalable or robust enough for system networked with multiple distributed facilities with a larger number of channels (100s). The approach presented here is a simpler, more robust method that continuously and in real-time calculates response spectra exceedance. Details on the novel approach are presented along with an example implementation for a very large energy production company.


BARCELONA, Spain--(BUSINESS WIRE)--Three companies are working together to help telecoms and carriers decrease the time required to create and deploy new networking services. These services based on virtualized network functions (VNFs) allow network operators to give customers the services they need faster and at a lower cost, increasing competitiveness and the opportunity to generate new revenues in a cloud-first world. Cloudify is a business unit of GigaSpaces, providing open source orchestration software for cloud applications and VNFs used by carriers and enterprises. A hackathon is being held at Mobile World Congress in Barcelona on March 1. The three companies —Cloudify, VMware and Intel—are presenting a tutorial on the use of a new VNF Onboarding Wizard developed by Cloudify. The wizard provides an easy to use, web-based interface for onboarding a VNF. The VNF Onboarding Wizard generates a template adhering to the TOSCA specification (Topology and Orchestration Specification for Cloud Applications), abstracting away from the VNF provider the need to understand the inner workings of the emerging open standard used by telecoms for VNFs. The VNF Onboarding Wizard provides a simple mechanism for VNF providers to generate a TOSCA compatible template. There is no industry standard for deploying a VNF onto a particular Virtual Infrastructure Manager (VIM). This has been the case for clouds using VMware vCloud Director® or OpenStack as a VIM. As a result, the onboarding process has been labor-intensive, requiring an in-depth knowledge of both the chosen Management and Operations (MANO) software and the VIM architecture. This lack of standards and developer abstraction has made the cost, time to market, agility and accuracy of new VNF deployments unattractive from a business standpoint. Recently, TOSCA blueprints have emerged as the forerunner in the emerging standards for VNF definition, supported by the MANO layer provided by the open source Cloudify project, which is TOSCA compliant. Cloudify significantly reduces time and risk to onboard new VNFs, and hence bring new services to market. Cloudify is working with the ONAP Project (formerly the Open-O project) to implement Common TOSCA and a VNF SDK to develop a new proposal for a standard VNF definition in TOSCA that addresses the specific VNF attributes and develops a new definition for network telemetry. This framework uses project ARIA for driving the TOSCA parser and validation. New Open Services Portal for VNF On-Boarding Demonstrated at MWC Also at Mobile World Congress, Cloudify is demonstrating a new open services portal together with VMware that showcases how carriers can launch and maintain the lifecycle of new VNFs easily through a customizable portal framework. The services portal provides a means to deliver VNFs after they have been onboarded through a multi-tenant catalogue service. The new framework also demonstrates how operators can easily create customized views for different user profiles, and tie in monitoring and telemetry in a single pane of glass user interface. “Cloudify continues our strong commitment to unlock the NFV, and specifically, VNF onboarding challenge through open source and open standards. The collaboration with VMware and Intel, alongside our work with the Open-O community, creates a platform for collaboration among organizations with aligned interests,” said Nati Shalom, founder and CTO of Cloudify. “This collaboration with Intel and VMware would not be possible without open source and an open standard to back it up.” “Open standards at the network infrastructure layer can drive innovation and new value further up the stack,” said Gabriele Di Piazza, vice president products and solutions, Telco NFV at VMware. “VMware is committed to open standards, and TOSCA is an ideal choice for VNF deployment and management because it’s already widely accepted in the telecom industry. Collaborating with Cloudify in using TOSCA to drive an open NFV standard is an ideal way to increase VNF adoption.” Cloudify is an orchestration-first cloud management platform that is open source and based on the TOSCA standard. Service providers and enterprises worldwide—including top financial firms, e-commerce companies, online gaming providers, healthcare organizations and telecom carriers—use Cloudify to enhance IT efficiency and performance at web scale.

Information can be delivered to a target person with maximum efficacy via a specific information transferer. We developed a compass system that established an anonymous method to analogize in-city acquaintances and used location information and each visitor's smartphone to detect analogically the significant influencers of a target person. Based on the data regarding information transferred between group members and their location history, we derived a model for estimating how acquaintances influence each other in a social group and for locating influencers. © Springer International Publishing Switzerland 2014.

Tree growth equations are an important and common tool used to effectively assess the yield and determine management practices in forest plantations. Increasingly, they are being developed for urban forests, providing tools to assist urban forest managers with species selection, placement, and estimation of management costs and ecosystem services. This study describes the development of allometric equations for Fraxinus americana and F. pennsylvanica growing in Oakville, Canada. With data collected from 103 ash trees, five allometric models were tested to develop equations estimating diameter-at-breast-height (dbh), tree height, crown width and crown height, using age and dbh as explanatory variables. Mean annual growth rates are presented to demonstrate species growth performance and were not significantly different over the first 40 years of growth for the two species. Of all the tested random coefficient models for both species, the cubic with weight 1/. x provided the best fit for estimating dbh from age. The best models for other parameters were the loglog for crown height from dbh, the quadratic for crown diameter from dbh, and the linear for tree height from dbh for F. americana. Model types showed more consistency for F. pennsylvanica with linear providing the best fit for crown diameter, crown height and tree height from dbh. The number of model types suggests the difficulty of fitting any single model to the vast array of conditions affecting plant growth in urban areas where management practices and environment can significantly influence tree size and growth. These models may be used to estimate the growth of ash tree populations in Oakville and communities with similar climate, soil, planting, and management environments. © 2013.

Sexuality and sexual function are important to persons with disabilities just as they are to their able-bodied counterparts, but knowledge about sexual and reproductive health (SRH) among persons with disabilities is frequently inadequate. Adolescents and young adults with physical disabilities are less active socially, and have difficulties in developing intimate relationships. Thus, despite greater needs for SRH education and service delivery than persons without disabilities, dedicated services regarding sexuality and physical disabilities are scantly reported. Together with a literature survey on sexuality and disability in adolescents, a unique comprehensive SRH service for young people with physical disabilities is described in this review. Despite being interdisciplinary, the utilization of the service was limited due to difficulties in transportation to the clinic and in finding escort for aid in accessibility to public transportation. Health authorities should provide the resources for the development of accessible comprehensive multidisciplinary SRH services dedicated to young people with disabilities, and thus fulfill the United Nations General Assembly declaration on the rights of persons with disabilities.

Occupants in essential facilities such as hospitals, emergency operations centers, strategic military installations, critical financial institutions, and nuclear power plants, cannot easily evacuate immediately after an earthquake and wait for a detailed safety assessment to reoccupy the facility and resume operations. Consequently, several leading technology and engineering consulting firms have teamed up to offer an Enhanced Rapid Post-Event Assessment service built upon utilizing the timely information afforded by structural instrumentation aimed to avoid unnecessary evacuation and shutdown and/or minimize expensive downtime. San Francisco, for example, and several other forward-thinking jurisdictions have established Building Occupancy Resumption Programs (BORP) that permit the building's "engineer-on-call" to be pre-deputized to perform the ATC-20 Red/Yellow/Green tagging of the building in lieu of official inspectors. Structural monitoring is a natural fit to these programs since engineers are assigned to a building in advance and thus already familiar with the building and its structural characteristics. The real-time monitoring systems provide intuitive onsite display, alerting, and remote notification on exceedance of demand/design parameters such as interstory drift, absolute acceleration, and response spectra. This information, which is continuously, immediately and remotely available to building personnel and consultants, is useful throughout all phases of the post-earthquake response, inspection, and recovery process. Presented here is an overview of the enhanced rapid post-event assessment solution along with several cases studies.

In response to an exponential growth in enrolments the Tutorial Support Management (TSM) model has been adopted by Open Universities Australia (OUA) after a two-year project on the provision of online tutor support in first year online undergraduate units. The essential focus of the TSM model was the development of a systemic approach to the provision of online tutorial support for high enrolment units. Findings from this project indicate that the TSM model has provided benefits in terms of improved student retention, performance, and satisfaction in addition to increased return and reenrolment rates. This paper outlines the key elements of the TSM model and offers comments on various issues that need to be taken into account in adopting this model. © 2010 Grace Lynch & Philip Paasuke.
