The Impact

The existing approaches to assessing the effectiveness of risk hedging with derivatives according to various criteria have been considered. As a result it was found that in economic literature it is not paid enough attention to the development of assessment methodology, which take into account the impact of risk hedging on the overall performance of the organization. In this regard, an economic approach to assessing the effectiveness of hedging has been proposed; it is based on the comparison two basic categories of the efficiency theory – the achieved effects and the associated costs. Within the framework of this approach the effects of hedging that affect the overallresult of the organization’s activities were proposed. Also the costs associated with hedging were systematized into external and internal. The essential content of the proposed economic approach is presented in comparison with other approaches, which contributes to understanding the criteria for assessment hedge effectiveness in each specific case. The application of the proposed economic approach in non-financial organizations will contribute to improving the quality of risk hedging by using performance assessment criteria that meet the current goals of the organization and the requirements of senior management.

Memory Structures

Call Level Interfaces (CLI) provide a set of functionalities to ease the connection between client applications and relational databases. Among them, the management of data retrieved from databases is emphasized. The retrieved data is kept in local memory structures (LMS) that allow client applications to read it and modify it through protocols. They are row (tuple) oriented and, while being executed, they cannot be preempted to start another protocol. This restriction leads to several difficulties when applications need to deal with several tuples at a time, namely in concurrent environments where several threads need to access to the same LMS instance, each one pointing to a different tuple and executing its particular protocol. To overcome this drawback, a Concurrent Tuple Set Architecture (CTSA) is proposed for LMS. A performance assessment is also carried out. The outcome is the evidence that in concurrent environments, the CTSA significantly improve the overall performance.

Image segmentation is one of the most challenging research fields for both image analysis and interpretation. The applications of image segmentation could be found as the primary step in various computer vision systems. Therefore, the choice of a reliable and accurate segmentation method represents a non-trivial task. Since the selected image segmentation method influences the overall performance of the remaining system steps, sky segmentation appears as a vital step for Unmanned Aerial Vehicle (UAV) autonomous obstacle avoidance missions. In this paper, we are going to introduce a comprehensive literature survey of the different types of image segmentation methodology followed by a detailed illustration of the general-purpose methods and the state-of-art sky segmentation approaches. In addition, we introduce an improved version of our previously published work for sky segmentation purpose. The performance of the proposed sky segmentation approach is compared with various image segmentation approaches using different parameters and datasets. For performance assessment, we test our approach under different situations and compare its performance with commonly used approaches in terms of several assessment indexes. From the experimental results, the proposed method gives promising results compared with the other image segmentation approaches.

ABSTRACTIn many countries, regulations for the management of nuclear waste require a performance (safety/risk) assessment to demonstrate the safety asserted to be provided by the sites/facilities proposed for handling, storing, and disposing of the wastes. However performance assessment can play a bigger role than solely demonstration of compliance with applicable safety standards in support of a regulatory decision (i.e., licensing of a waste management facility). Performance assessment can be an effective management tool during all phases of a waste management program: from development of national nuclear waste management policies; to programmatic environmental impact assessments associated with design and siting evaluations, site selection, and site characterization; to licensing and operation of facilities.International experience has demonstrated that nuclear waste management programs are long-term efforts, lasting at least two to three decades from initial policy development to licensing and commencement of waste management and disposal operations. This experience has also demonstrated that consistent attention to, and integration of, initial component studies are necessary to provide a comprehensive total system analysis for programmatic environmental impact assessments and for licensing.For nearly 40 years, Sandia National Laboratories has developed and applied a performance assessment methodology in numerous national and international nuclear waste management programs. These applications range from development and feasibility testing of environmental health standards to preliminary evaluation of waste disposal sites; to establishing the basis for demonstration of compliance; to informing licensing (compliance demonstration) decisions. In many of these applications the performance assessment methodology has also served as a management tool for confirming the added value of research and development investments.This paper presents examples to illustrate how performance assessment has been used as an effective management tool through multiple phases of a nuclear waste management program.

In this paper landslide susceptibility mapping and model performance assessment was conducted using three models, logistic regression, GAM, and SVM, in a study area in Shenzhen, China. Ten factors, slope angle, aspect, elevation, plan and profile curvature of the slope, lithology, NDVI, building density, the distance to the river, and the distance to the fault were selected as influencing factors for the landslide occurrences. All three models were trained and the resulting susceptibility maps were created. The performances of the three models were then assessed by AUC values through a 10-fold cross-validation. It could be concluded that in the study area GAM had the best overall performance among the three models, while SVM was better than logistic regression. Based on the derived DPR values, the optimum thresholds between stable areas and risky areas for all three models were also determined.
