Modular Energy-Efficient and Robust Paradigms for a Disaster-Recovery Process over Wireless Sensor Networks
No full textRobust paradigms are a necessity, particularly for emerging wireless sensor network (WSN) applications. The lack of robust and efficient paradigms causes a reduction in the provision of quality of service (QoS) and additional energy consumption. In this paper, we introduce modular energy-efficient and robust paradigms that involve two archetypes: (1) the operational medium access control (O-MAC) hybrid protocol and (2) the pheromone termite (PT) model. The O-MAC protocol controls overhearing and congestion and increases the throughput, reduces the latency and extends the network lifetime. O-MAC uses an optimized data frame format that reduces the channel access time and provides faster data delivery over the medium. Furthermore, O-MAC uses a novel randomization function that avoids channel collisions. The PT model provides robust routing for single and multiple links and includes two new significant features: (1) determining the packet generation rate to avoid congestion and (2) pheromone sensitivity to determine the link capacity prior to sending the packets on each link. The state-of-the-art research in this work is based on improving both the QoS and energy efficiency. To determine the strength of O-MAC with the PT model; we have generated and simulated a disaster recovery scenario using a network simulator (ns-3.10) that monitors the activities of disaster recovery staff; hospital staff and disaster victims brought into the hospital. Moreover; the proposed paradigm can be used for general purpose applications. Finally; the QoS metrics of the O-MAC and PT paradigms are evaluated and compared with other known hybrid protocols involving the MAC and routing features. The simulation results indicate that O-MAC with PT produced better outcomes.https://doi.org/10.3390/s15071616
Slovenia, Country Risk, and FDI -Three Levels of Analysis Mixed Methodologies Offer Fresh Insights
No full textThe purpose of this study is to discover relationships among FDI (Foreign Direct Investment), country risk, investor expectations, and certain financial variables in Slovenia, and to do this on three levels of analysis: standard statistical analysis, chart or graphical analysis, and a qualitative field study. The quantitative work displays relationships of the variables using cointegrationand VAR analyses. The chart section imposes visually the variable of country risk on the same data source as the statistical analysis. And the field study incorporates aspects of international finance such as legal, historic, social, and political issues into the research

Effects of light intensity on leaf production under water stress in two different strains of Arabidopsis thaliana
No full textLight and water are important components for photosynthesis and their availability in the wild can vary considerably. Plants must have mechanisms to deal with variation in order to continue growth despite less than optimal conditions.The growth of two strains of Arabidopsis thaliana was tested under various combinations of high and low light intensity and water availability conditions. The strains were monitored to determine any significant differences in the quality and rate of growth. Two strains were used in the experiment in order to observe differences in their ability to cope with the specified conditions. Mt-0 is a strain from Libya,while Col-0 is laboratory strain originally selected at University of Missouri-Columbia. Libya is located at a low latitude in a desert biome and therefore, Mt-o should be better at acclimatizing to high light intensity and low water conditions than the laboratory strain, Col-o
