The mission of the JOMAse is to foster free and extremely rapid scientific communication across the world wide community. The JOMAse is an original and peer review article that advance the understanding of both science and engineering and its application to the solution of challenges and complex problems in naval architecture, offshore and subsea, machines and control system, aeronautics, satellite and aerospace. The JOMAse is particularly concerned with the demonstration of applied science and innovative engineering solutions to solve specific industrial problems. Articles preferably should focus on the following aspects: new methods or theory or philosophy innovative practices, critical survey or analysis of a subject or topic, new or latest research findings and critical review or evaluation of new discoveries. Scope The JOMAse welcomes manuscript submissions from academicians, scholars, and practitioners for possible publication from all over the world that meets the general criteria of significance and educational excellence. The scope of the journal is as follows: Naval Architecture and Offshore Engineering Computational fluid dynamic and Experimental Mechanics Hydrodynamic and Aerodynamics Noise and Vibration Aeronautics and Satellite Engineering Materials and Corrosion Fluids Mechanics Engineering Stress and Structural Modeling Manufacturing and Industrial Engineering Robotics and Control Heat Transfer and Thermal Power Plant Engineering Risk and Reliability Case studies and Critical reviews

Abstract

The movement of ice ship gradually gives load to the ice sheet, along with that, the ice sheet will react in proportion to the load of the ship. The phenomenon of interaction between ice and hull of ship has been studied by researchers through empirical mathematical simulation and experiment. This paper discusses the phenomena of ice sheet buckling and deflection caused by a ship sailing in ice level. The ice sheet buckling and deflection is analyzed based on using Finite Element Method based on Euler and Cantilever methods. The methods were described from general deflection equation for a beam. Simulation was carried out using Abaqus running ahead and astern at several speeds of 0.4m/s, 0.5m/s and 0.6m/s.

Abstract

At present the determination of weight and volume has been widely used to assist in the process of determining costs for freight forwarding services. Shipping costs are determined by the weight of the goods, but the weight of the goods consists of two types, namely actual weight and volume weight. The weight of the weighing will be used directly if the item or box is small, but if the item is large but the weight is real then the weight of the volume will be used. Algorithms that combine triangulation and 2D measurement techniques can be used to build 3D surfaces so they can measure the volume of a product. Determination of volume in the optical scoring system can be done using the laser triangulation method and the area of 2D image measurement, then using a computer algorithm to get the results of 3D images to determine the volume of the object. The calculation process used in this study uses MATLAB software. MATLAB is the most efficient software for matrix-based numerical calculations and is widely used in mathematical calculations, development and algorithms, programming modeling, prototyping and simulation, data analysis, exploration and visualization, numerical and statistical analysis, and technical application development. The results of the study using MATLAB include students becoming more interested in learning and more independent in learning mathematics, can visualize data graphically to help analyze the data analyzed, and help in modeling the characteristics of variations in fuel mixtures which include density, viscosity, dynamic and kinematic viscosity.
