The southwest Indian Ocean is an important area for deep-sea investigation and exploration. In this paper, the spatial distribution temporal variation characteristics of wave elements in sea were analyzed by using high resolution reanalysis data (ERA) from European Center, optimal path set tropical cyclones provided Joint Warning Center (JTWC) global ocean circulation model (OFES). results show...

Article introduces and discusses the sensors used in autonomous cars. The reliability of these devices is crucial for proper operation driving systems. research works related to issue performance adverse weather conditions discussed critically analysed. negative effects caused by bad are characterised. paper presents result author's own concern on rain, snow fog lidar measurments. results obtai...

Most of the research on ship rolling motion concerns a specific type ship, such as containerships, or analyzes sailing during certain wave characteristics, rather than full spectrum waves that can be encountered entire sea route. To date, most frequent merchant ships in world are general cargo ships, where ship’s behaviour at any condition has great influence overall safety, well lashing design...

investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (lhr) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].the engine had different operating conditions...
