Short communication: Identification of By-catch species of tuna purse seiners in Iranian waters of Oman Sea

Tuna purse seine fishery is a commercial and industrial fishery in the Iranian waters of Oman Sea. An observer programme was conducted to identify the by-catch composition of the tuna purse seine fishery in the Iranian waters of the Oman Sea. Investigations were carried out on board of purse seiner vessel “named Parsian Shila” between September and October 2015. The by-catch was composed of 17 ...

The Considerations of Vibrations and Noise at the Preliminary and Contract Levels of Ship Design

The nature and the extent of the engineering effort devoted to vibration and noise up to and including the contract design of ships are dependent on several factors. The key factors are related to the Ownert s philosophy on design and on the availability of suitable analyses procedures. Much reliance is placed on past design practices and experience. It is fairly usual to estimate and compare n...

Automatic Ship Detection in Space-borne Sar Imagery

Synthetic aperture radar (SAR) imagery has proven to be a promising data source for the surveillance of maritime activity, and its application for automatic ship detection has been the focus of many research studies. Apart from the well-known CFAR detector, there has emerged a novel method for automatic ship detection, based on the wavelet transform. Since the underlying principles for both met...
