At the time of the diesel engine work may lead to heat. The heat generated from the combustion of fuel in the cylinder. The heat generated in the engine block require refrigeration. Definition of cooling water temperature itself is the water that is circulated continuously on the system by the value of the allowable temperature to cool and prevent expansion, overheating and also aims to prevent damage to the metal, material fatigue of deformation on the machine. Given the importance of the function of the cooling system, the existence of Reviews These systems should be treated properly. In this case I use a Fishbone method where this method is to categorize the various potential causes of a problem or issue in a way that is Easily understandable and presentable. In the which the author has Carried out onboard practice and Participate Observe disturbances contained in diesel engine cooling water systems machinery onboard generator along with officers during a high temperature of cooling water, on the 17th of June 2015 in the Java Sea. The authors formulate the problem is. What factors are causing the failure to Achieve the cooling water temperature?. How to treat the cooling water system to keep it in good working order to Achieve the cooling water temperature is normal?. The result can be concluded that the work can be used as guidelines when operating on diesel engine generator, cooler system dirty, dirty filter sea chest, the wear on the impeller, the wear on the bearings. So to do maintenance and repair is to maintain the cleanliness of the cooler, the cleanliness of the sea chest filter, replace the impeller and replace a worn bearing in order to achieve a normal pressure. With the maintenance and repair of the cooling system is expected cooling water temperature can be achieved by normal, the damage can be detected early and durability of the machine can last a long time.

Creating 3D models of cultural heritage sites with terrestrial laser scanning and 3D imaging
No full textIncludes abstract.Includes bibliographical references.The advent of terrestrial laser-scanners made the digital preservation of cultural heritage sites an affordable technique to produce accurate and detailed 3D-computermodel representations for any kind of 3D-objects, such as buildings, infrastructure, and even entire landscapes. However, one of the key issues with this technique is the large amount of recorded points; a problem which was even more intensified by the recent advances in laser-scanning technology, which increased the data acquisition rate from 25 thousand to 1 million points per second. The following research presents a workflow for the processing of large-volume laser-scanning data, with a special focus on the needs of the Zamani initiative. The research project, based at the University of Cape Town, spatially documents African Cultural Heritage sites and Landscapes and produces meshed 3D models, of various, historically important objects, such as fortresses, mosques, churches, castles, palaces, rock art shelters, statues, stelae and even landscapes
