People are motivated according to their needs. These needs vary according to the time and based on various situations. Identifying and assessing human needs are the first and vital step in determining the amount of its impact on work and activity. According to these facts, the aim of this research is to identify the needs of the Iranian seafarers on board merchant ships. It also tries to spec...

Detecting ships in marine images is an essential problem in maritime surveillance systems. Although several types of deep neural networks have almost ubiquitously used for this purpose, but the performance of such networks greatly drops when they are exposed to low size and low contrast images which have been captured by passive monitoring systems. On the other hand factors such as sea waves, c...

Labor groups, environmental activists, and shipping experts have begun finalizing international guidelines that would reduce threats from toxic substances released during the ship scrapping process and would protect the health and safety of laborers who dismantle ships. In June 2001, government representatives and stakeholders in the ship dismantling industry gathered in Geneva, Switzerland, to...

It is not enough to seek solutions to these problems from the standpoint of an individual technical or industrial group, or even that of a nation; the whole subject needs a detailed review at the widest international level. Shipping itself is essentially an international operation and the hazards that it may entail are seldom of a purely national or even regional character. This is particularly...

Advanced control algorithms using LQG and adaptive control techniques enable the design of an economically attractive alternative for conventional fin stabilizers and have proved to be robust during simulation experiments and full-scale trials. Abstract-This paper describes the design of an autopilot for rudder roll stabilization for ships. This autopilot uses the rudder not only for course kee...

Being in a ship is like being in jail, with the chance of being drowned (Dr. Samuel Johnson) Gastroenteritis is a major health concern aboard cruise ships [1]. Poor sanitation systems and contaminated water and food used to get the blame. As the North American market covers 2/3 of the global cruise volume [2], the U.S. Centers for Disease Control and Prevention (CDC) were particularly intereste...

OBJECTIVES To investigate the frequency, circumstances, and causes of occupational accidents aboard merchant ships in international trade, and to identify risk factors for the occurrence of occupational accidents as well as dangerous working situations where possible preventive measures may be initiated. METHODS The study is a historical follow up on occupational accidents among crew aboard D...
