چکیده
Currently, water jets are mainly used in the fields of mechanical processing and mining collection. This paper creatively introduces them to field safety assurance for inland navigation. Compared with traditional bridge anti-striking methods such as intelligent early warning passive anti-striking, this method can form an “interference zone” by changing flow conditions local areas, causing yawing moment yaw ship change, thereby ship’s course thus guiding move away from pier realize active ship. In paper, a combination generalized model testing numerical simulation was study effects different nozzle pressures distances water-jet generator on trajectory drift angle stalled The results showed that good agreement test results. Within interference zone, distance between increased rapidly after action disturbance zone 9.1, 5.8, 6.2 times width, respectively, reaching safe distance. During process being affected maximum less than 20°, generally stable, comparison error 10.6%, minimum 3.5%, average 6.7%. A negative peak positive four absolute value occurred yaw-moment ephemeral curve during passage through area. had notable effect ships two invention patents applied research.

A Survey on Ship Collision Risk Evaluation
Recently, ship collision avoidance has become essential due to the emergence of special vessels like chemical tankers and VLCCs (very large crude carriers), etc. The information needed for safe navigation is obtained by combining electrical equipment with real-time visual information. However, misjudgements and human errors are the major cause of ship collisions according to research data. The ...

A Process for Developing the Statement of Internet Research Ethics based on Action Research Method
Background: Research ethics in cyberspace or Internet research ethics (IRE) is a subset of applied ethics that aims to study, introduce, and apply ethical codes for guiding research activities in cyberspace. The compilation of the ethical statement is based on two methods of documentary research and action research. The action research process is implemented in four stages: 1) diagnosis, 2) act...
متن کاملResearch of Matrix-based Grouping Method on Anti-collision Algorithm for RFID Tag Identification
Abstract Currently, the Binary Search Tree (BST) algorithm is mainly used for continuous identification signal processing on active RFID tags. However, tag population is unlimited increasing. With using the BST, the number of identified tags is limited at an average period of time. In this paper, we propose the BST algorithm of the matrix-based grouping to accelerate the recognition speed of ta...
