Abstract Ship locks are the most widely used, promising, and important type of navigation structure in world at present. It is, therefore, crucial to evaluate operation safety a ship lock service. However, determination indicator thresholds is challenging. Accordingly, this paper describes systematic study evaluation system safety. First, accidents counted. According rhombic thinking mode (that...

To evaluate the fidelity of the iDental system and investigate its utility and performance on simulated drilling operations, user studies consisting of objective and subjective evaluations were performed. A voxel-based drilling simulation sub-system in the iDental system was employed for evaluation. Twenty participants were enrolled to take part in the experiments and were divided into two grou...

UNLABELLED BACKGROUND OF THE PROBLEM: We perform high tibial osteotomy with knee debridement and forage. GOAL We evaluated the results of operations in 47 patients, who were operated from 1st January 1998 to 31st of December 2000. RESULTS We examined the patients before operation and 2, 4, 6, 12, 24 and 30 months after it. The follow up was from 6 months to two and a half years after operat...

PISA, the OECD’s international program of assessment of reading, scientific and mathematical literacy, aims to assess the knowledge and skills that students have acquired at school and their ability to use them in everyday tasks and challenges. It also uses questionnaires to gather data on students’ attitudes to learning and the conditions of schooling. Since 2000, PISA has tested the scientifi...

We introduce SentEval, a toolkit for evaluating the quality of universal sentence representations. SentEval encompasses a variety of tasks, including binary and multi-class classification, natural language inference and sentence similarity. The set of tasks was selected based on what appears to be the community consensus regarding the appropriate evaluations for universal sentence representatio...

For example, the OECD Program for Internat...

In the implementation of many public key schemes, there is a need to perform modular arithmetic. Typically this consists of addition, subtraction, multiplication and (occasionally) division with respect to a prime modulus. To resist certain side-channel attacks it helps if implementations are “constant time”. As the calculations proceed there is potentially a need to reduce the result of an ope...

BACKGROUND Globally, health expenditure as a percentage of GDP has increased in recent years, so evaluating the health care systems used in different countries is an important tool for identifying best practices and improving inefficient health care systems. OBJECTIVE We investigate health system efficiency at the country level based on OECD health data. We focus on several aspects of health ...

Since about 1990, many developing and transition countries have undertaken market-oriented reforms in their electric power sectors. Despite the widespread adoption of a standard policy model, reform processes and outcomes have often failed to meet expectations. Drawing on an extensive literature review and case studies in Asia, Africa, Latin America, and Eastern Europe, this paper describes com...
