The objective of spatially-aware access control models is to regulate the access to protected objects based on position information. In that last years, increasing attention has been paid to spatiallyaware access control models for mobile and pervasive applications. Following the experience of design of the GEO-RBAC model, in this paper we want to look at those models with a critical eye and po...

Information access is becoming increasingly heterogeneous. We need to better understand the more complex user behaviour within this context so that to properly evaluate search systems dealing with heterogeneous information. In this paper, we review the main challenges associated with evaluating search in this context and propose some avenues to incorporate user aspects into evaluation measures.

The European Medicines Agency must fulfil its transparency obligations and resist industry pressure.

The impacts of microplastic (MP) pollution in the marine environment have already been illustrated by natural science. issues resulting from MPs revealed problem current international governance arrangement, and agreements are found to be inadequate curb growing MP pollution. This article explores reasons for failure cooperation legal normativism positivism. By analyzing semi-closed sea system ...

It is common practice to fold pressure-time diagrams of compressors into pressure-volume diagrams because the latter are of special thermodynamic significance. For example, the enclosed area represents piston work. The folding is accomplished utilizing knowledge of the top dead center position and kinematic relationships of the compressor. It was found that even a small measurement error of the...

UNLABELLED To protect occupants from infectious diseases or possible chemical/biological agents released by a terrorist in an enclosed space, such as an airliner cabin, it is critical to identify gaseous contaminant source locations and strengths. This paper identified the source locations and strengths by solving inverse contaminant transport with the quasi-reversibility (QR) and pseudo-revers...

the study analyzed farm households’ access and utilization of government health facilities in kogi state, nigeria. specifically, it described the socioeconomic characteristics of farm households, determined the level of accessibility to health facilities by farm households, and determined the factors that drive farm households’ utilization of government health facilities. a two staged random sa...

This article explores the approach of international human rights bodies to conscientious objection abortion, by requiring states implement mandatory referral mechanisms where is permitted. This, however, represents an inadequate compromise position as many objecting healthcare professionals also object and circumvent those requirements. Furthermore, cannot address broader issues with overuse mi...
