Efficient Extended ABAC Evaluation
Proceedings of the 23nd ACM on Symposium on Access Control Models and Technologies, 2018© 2018 Association for Computing Machinery. A main challenge of attribute-based access control (ABAC) is the handling of missing information. Several studies show that the way standard ABAC mechanisms (e.g., XACML) handle missing information is flawed, making ABAC policies vulnerable to attribute-hiding attacks.

Evaluating the Evaluations: Evidence From Energy Efficiency Programmes in Germany and the UK
Energy and Buildings, 2013 To make robust judgments of an energy efficiency programme’s economic effectiveness, we need to know how much energy and CO2 is actually being saved through the financial support it provides.

Evaluating the efficiency of Linda implementations
Concurrency and Computation: Practice and Experience, 2017SummaryAmong the paradigms for parallel and distributed computing, the one popularized with Linda, and based on tuple spaces, is one of the least used, despite the fact of being intuitive, easy to understand, and easy to use. A tuple space is a repository, where processes can add, withdraw, or read tuples by means of atomic operations.

Inspired by the best querying performance of ViST among the rest of the approaches in the literature, and meanwhile to overcome its shortcomings, in this paper, we present another efficient and novel geometric sequence mechanism, which transforms XML documents and XPath queries into the corresponding geometric data/query sequences. XML querying is thus

Evaluating port efficiency in the Mediterranean
International Journal of Data Analysis Techniques and Strategies, 2013During the last years, there was rapid development in the world port industry which is considered to have resulted from the increase of universal trade. The key to the development of each port is its adaptability to the earliest developments and its resistance to the increasing competition.

Efficiency Evaluation for the 3G and WiMAX
2009 Fifth International Joint Conference on INC, IMS and IDC, 2009When the client moved quickly, from 3G into WiMAX service coverage, then leaved the WiMAX service coverage and accessed to another 3G range of services. At this time, that handoff frequently in a short period of time, and decreased system efficiency, also decreased the QoS. In this research, we use NS-2 to simulate the situations.

An Efficient Infertility Evaluation
Clinical Obstetrics & Gynecology, 2011The biological clock is a major adversary to human reproduction. Not only does fecundity wane with time, but so does an infertility patient's emotional reserve. Therefore, a well-organized approach to evaluating, treating, and referring patients to subspecialty centers when necessary is critical to optimally manage infertility.

The Human Efficiency Evaluator
2017With more and more systems and machines operating autonomously, the role of the operator is changing from “being actively in control” to “monitor and intervene”. Human Machine Interfaces (HMI) therefore need to be optimized so that they can efficiently be monitored by a human.

Efficient evaluation of splines
Computing, 1984An algorithm is presented to compute the Taylor expansion of a polynomial B-spline function from its de Boor points. It is shown to be more efficient than existing methods and has the additional advantage of being reversible.

Efficiency Evaluation in Search Advertising
Decision Sciences, 2013ABSTRACTIn this article, we use data envelopment analysis combined with principal component analysis to evaluate the efficiency of online retailers in search advertising. We examine various efficiency model specifications involving several resource and performance‐related variables in search advertising.
