Attempts to prevent invasion of marine biofouling on marine vessels are demanding. By developing a system to detect marine fouling on vessels in an early stage of fouling is a viable solution. However, there is a  lack of database for fouling images for performing image processing and machine learning algorithm.

This study was conducted in Mayaguez – Puerto Rico, and an area of around 18 Km2 was covered, which were determined using the following classification of places:

·         Main Avenues: Wide public ways that has hospitals, vegetation, buildings, on either side

·         Open Places: Mall parking lots and public plazas

·         Streets & Roads: Dense residential and commercial areas on both sides

The paper is aimed at an investigation of the features of a tubular-linear synchronous quasi-Halbach machine (T-LSM) where the radially-magnetized PMs are substituted by four equal segments with parallel magnetization. Such a substitution is done in an attempt to improve the machine cost-effectiveness which makes it a viable candidate to equip free-piston engine-based series

The uncertainties in diesel engine parameters often result in an inaccurate model. The data describe the actual data to identify the faults using exploratory data analysis to avoid high shipping cost.
