With the rapid development of cyberspace and smart home technology, human life is changing to a new virtual dimension with several promises for improving its quality. Moreover, the heterogeneous, dynamic, and internet-connected nature of smart homes brings many privacy and security difficulties. Unauthorized access to the smart home system is one of the most harmful actions and can cause several trust problems and relationship conflicts between family members and invoke home privacy issues. Access control is one of the best solutions for handling this threat, and it has been used to protect smart homes and other Internet of Things domains for many years. This survey reviews existing access control schemes for smart homes, which concern the essential authorization requirements and challenges that need to be considered while designing an authorization framework for smart homes. Furthermore, we note the most critical challenges that other access control solutions neglect for smart homes.

International Soil and Water Conservation Research 2018年第2期6卷 194-201页

Talakhaya watershed in Rota is identified as a Coral Reef Management Priority site for CNMI (Com-monwealth of Northern Mariana Islands). In 2010 federal and jurisdictional partners developed a Con-servation Action Plan (CAP) for the Talakhaya Watershed. The goal of this initial Watershed Soil Loss Assessment therefore, was to assist in evaluating the re-vegetation objectives of 'Mitigating Sediment Load' in the Talakhaya watershed by making a thorough characterization of its main river systems. The objectives of this project were to reach those goals by measuring the hydrological parameters following the installation and the use of water meters, barometric level loggers, turbidity meters and rain gauges. The water flow as well as the turbidity level of each stream leading to the ocean from the Talakhaya Watershed was measured and sedimentation level was assessed accordingly. The results from the monitoring of the watershed conducted during the project timeline reported here show that all four rivers under study have statistically different stage-discharge curves. The river's relationship between time and turbidity also vary especially in the summer months of the first-year observations. Linear and convex polynomial relationships were sometimes observed in the different rainfall groupings for the four river systems, however relationships were often not significant. This-being-said, Quantile Regressions suggest that when data from all four river systems are combined for cases where there is some de-tectable rainfall, a maximum possible turbidity level can be defined.

Twenty two haplotypes were generated from a pool of 60 unrelated Saudi β thalassemia major patients using previously described restriction sites in the β globin gene. Linkage disequilibrium analysis of the polymorphic sites was also conducted, a few identified haplotypes were novel while the remainder was previously reported, haplotype1222212 was the most frequent haplotype in the study group and a strong linkage disequilibrium between two polymorphic restriction sites in these β thalassemia patients was uncovered.
