Underwater Communication Using UAV to Realize High-speed AUV Deployment

To monitor the detail information in the sea and on the seafloor, sensors are generally installed on Autonomous Underwater Vehicle (AUV). AUV cannot accurately grasp the absolute position and needs to communicate with the sea-surface vehicle. However, the sea-surface vehicle cannot perform observation operations at high speed and with high efficiency due to low mobility and high human and financial costs. From this perspective, Unmanned Aerial Vehicle (UAV) has possibilities as the next-generation platform. In this study, we conducted a demonstration experiment to use UAV as a sea-surface base for AUV’s underwater communication. We additionally verified the capability of UAV, which can land on and separate from the sea surface, as a drifting buoy to monitor underwater data. Experiment results and obtained data suggest that UAV is suitable for a research operation near the coastal region in terms of position keeping ability, performance against sway, and operation speed as a communication base. To carry out more complicated work (transportation of AUV, etc.) with UAV, new research and development such as weight reduction of AUV will be required.

Professorial Entrepreneurial Research: An Innovative and Comprehensive “Tri–Analytics Engine” via “Triodynamics” that uses In-Depth Triostatistics to Establish a Longitudinal Faculty Research Agenda

The narrative in this paper provides an in-depth, novel, and innovative methodology to aid higher education faculty in the production of an innovative research agenda designed to trichotomously sustain, advance, and prolong their existing careers. The methodology used to do the aforementioned is referred to as the “Tri–Analytics Engine”. A “Tri–Analytics Engine” is a pioneering initial and accumulative advanced post hoc research practice grounded in Triostatistics. The Tri–Analytics Engine has an introductory methodology termed “Triodynamics” as starting foundational “base research operation” that sets the stage for future research efforts that have their foundation in the initial research topic. Triodynamics are a set of three trichotomous standards that aid the investigator in the creation of a post hoc research agenda after the primary Tri–Analysis analytic. A Tri–Analytics Engine is also a personal entrepreneurial inquiry-based ethos that is trichotomously complex, comprehensive, and cumulative that has Triostatistics at its core.

Ethical considerations in the biomedical research: analysis of national biomedical research ethics guidelines in Iran

The national guidelines for biomedical research ethics are approved by the “National Committee for Ethics in Biomedical Research” at the Iranian Ministry of Health and Medical Education as the regulatory body for biomedical research in the country. The focus of these guidelines should be on the ethical issues related to different stages of the research process, which would lead to increased research integrity and better supervision of research activities. The present study analyzed the contents of these national guidelines to clarify the ethical considerations connected to the five stages of a research process including 1) proposing, 2) approval, 3) operation, 4) documentation and 5) publishing. The findings showed that the assessed guidelines laid more emphasis on the ethical considerations related to the research operation stage rather than the proposal stage. In other words, activities such as identification of the research problem, formulation of hypotheses and questions, financial evaluation, data analysis and data interpretation did not receive adequate attention in these guidelines. Most of the guidelines presented subject categories such as the rights of participants and supervisory considerations in the “research operation stage”, ethical considerations in the “evaluation and approval procedure stage”, and editorial responsibilities in the “research review and publication stage”. In general, despite noticeable content for guiding researchers for ethical conduction of research the national guidelines are not adequately developed to cover comprehensive and sufficient ethical considerations regarding all the activities of research.

Potential of indigenous bacteria to remove cyanide with variations of contact time and temperature

The research on environmental biotechnology has been done in aims to study the ability of mixed culture indigenous bacteria to remove cyanide (KCN-) concentration which is determined by environment conditions of temperature and contact time. The research has been done using the artificial pollutants that contains 500 ppm of KCN- which is exposed to the SMSS (Stone Mineral Salt solution) as a growth media for mixed culture bacteria TBS and CTS. The effect of different environment conditions including temperature and contact time were studied on cyanide removal. Gas Chromatography - Mass Spectrophotometer (GC - MS) method is used to analysed the concentrations of KCN-. Initial condition of research operation is determined to be pH 7 and contact time of 48 hours. The removal of 500 ppm KCN- increases to 71% at incubation temperature 35°C and contact time of 36 hours. This research showed that indigenous bacteria TB1 and CS2 can remove 500 ppm KCN- on all temperature variations between (°C) 25 to 45 and the highest removal occur when contact time is 36 hours.

Study on Generalized Hamiltonian Model of Hydraulic Generator Unit with Elastic Water Column

In this paper, nonlinear turbine model and hydraulic system which is one penstock one machine dynamic differential equation with elastic water column are combined. Hamiltonian function of hydraulic turbine is constructed. By applying Hamiltonian orthogonal decomposition realization and dissipation realization method, generalized Hamiltonian model of hydraulic turbine is built. Connected with generator third-order Hamiltonian model of single machine infinite bus system, generalized Hamiltonian model of hydraulic generator unit is established. This paper provides certain theory basis for research operation and control dynamics mechanism of hydraulic generator unit in generalized Hamiltonian system framework.
