Abstract With the development of digital instrument and control technology for nuclear power plants in recent decades, communication networks have become an important part of safety digital control systems, which takes charge in data exchange between the various sub-systems, and extremely impact on the reliability and safety of the entire I&C system. Traditional communication systems where some special features, such as reliability, safety, real-time, certainty, and independence are not strictly required are various illustrated. However, how to implement a communication system in a safety I&C system is rarely stated in current research. In this research, a reliable safety communication system applied in nuclear power plants is designed and analyzed. The five key characteristics of nuclear safety communication networks are explained, followed by explanation of how to achieve these characteristics. The analysis and verification of the designed system are also stated in this paper, which contributes to proving that the designed nuclear safety communication system could applied in the nuclear power plants.

Limited Basis

All mines have safety problems and underground mines tend to be thought of as more dangerous than surface mines. Safety communication systems typically found in Zambian underground mines include hardened telephone systems coupled with the Locked-Bell System, mine radios, leaky feeder systems and on a limited basis, digital systems. These systems depend upon a hard-wired support and if communications cable(s) become damaged or severed at any point, all communications in and out of an underground mine are disrupted. Additionally, fire, explosion or water inundation is likely to compromise communications cables and as such they cannot be relied upon for emergency communication purposes. These challenges lead to safety communication underground difficult and sometimes results in fatality when an accident happens. In this study, therefore, communications software is developed for underground mines to improve safety communication. An accident reporting and logging database based system is designed which shall incorporate the digital version of Form 55 used at Ministry of Mines and Minerals Development in Zambia. The communication software is developed using Real Basic programming language which is an object-oriented invent driven Language and Structured Query Language (SQL), a database management design and maintenance language. The communications software was developed and tested on a virtual and actual server-client networks i.e. it provided a two-way texting and chatting system, which is useful in relaying of information between the surface and teams working underground. The clients to be deployed underground will have a unique ID which can be referenced to give details on the locations. This can further ease the search for the miners in case of total loss of communication and accidents. The Mines Safety and Accident Communication System (MISACOMS) Reporting and Logging system was developed and tested on various operating systems. The digital format of Form 55 provided an ease way of logging, reporting and cross referencing accident data as it is stored in a database.

Unmanned aerial vehicle (UAV) is a flight device with power and energy based on computer program control, which has the characteristics of small size, light weight, high maneuverability and low cost. With its characteristics, UAV can play an important role in military and civil fields. However, due to the broadcast nature of wireless communication and inherent air-to-ground line-of-sight channel, UAV wireless communication system is more vulnerable to security threats. On the basis of traditional encryption technology, the secrecy capacity of the UAV communication system can be improved by introducing physical layer security. This article aims to study the security of the physical layer in the UAV communication system, and summarizes the latest research results on the safety communication involving UAVs on the physical layer, such as trajectory optimization, power allocation, user scheduling and cooperative UAVs. Further, some potential research directions and challenges in physical layer security of UAV system are discussed.

The article presents the generalization of the experience of using simulator technologies in forming the competence to future navigators regarding the use of radar equipment and global maritime communication system in case of disasters and to ensure safety.It has been found that the amendments made by the International Maritime Organization to the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers have expanded the role of simulators in assessing the relevant competencies of maritime professionals. At the same time, it should be noted that logistical support of maritime higher educational institutions lags behind the requirements of modern shipping industry, the requirements of the seafarers’ labor market, and so on. It is a systemic problem that encompasses all levels of training and skills upgrading for shipping industry professionals. To solve the problem of improving the quality of professional training it has been proposed to carry out this process taking into account the principles of contextual approach, providing for the use of modern equipment and simulators, which departments and laboratories of maritime higher education institutions are equipped with. Training on simulators occupies a special place in the training of navigators, because it allows to exercise modeling of situations, which reproduce the conditions as close as possible to the real world. It is also important to include into the content of academic disciplines some components of simulator training on the formation and development of skills to work with electronic mapping systems, radio and electro-navigation equipment of ships, as well as skills associated with maritime safety (operation of fire-fighting equipment, rescue equipment, first aid on board ship, cargo operations with heavy cargo and containers, etc.). Each of these courses is taught in specialized laboratories equipped with the necessary simulation equipment in accordance with international requirements for training maritime professionals and the requirements of employers.

Feature Match

The purpose of this article is to outline a decision-making process and highlight which portions of the augmentative and alternative communication (AAC) evaluation process deserve special attention when deciding which features are required for a communication system in order to provide optimal benefit for the user. The clinician then will be able to use a feature-match approach as part of the decision-making process to determine whether mobile technology or a dedicated device is the best choice for communication. The term mobile technology will be used to describe off-the-shelf, commercially available, tablet-style devices like an iPhone®, iPod Touch®, iPad®, and Android® or Windows® tablet.
