Trajectory analysis and extraction of trajectory patterns are crucial to enhance marine safety and marine status awareness. The major data source for such analysis is Automatic Identification System (AIS), which publishes data related to movement of the ship while cruising. AIS broadcasts information including type of ship, identity number, state, destination, estimated time of arrival (ETA), location, speed, direction, and cargo. In this paper, we focus on extracting a variety of trajectory patterns for maritime vessels. The first group of analysis we focus on is arrival port, arrival time, and next position prediction on AIS messages, which are useful to aid maritime operators. We propose three different approaches for the prediction of marine vessel movement. As the second type of analysis, anomaly detection on marine vessel trajectory is studied. For vessel movement prediction, the experiments show that the proposed solutions brought improvement against conventional supervised learning approaches. The proposed anomaly detection technique is demonstrated on a case study.

The Vessel route pattern extraction and anomaly detection from AIS data Boztepe, Gözde; Karagöz, Pınar; Department of Computer Engineering (2019) The need for a variety of auxiliary analytical tools to enhance marine safety and marine status awareness has been expressed by various platforms. There are lots of data sources breaking out while the ship is on cruising. Automatic Identification System (AIS) device that is widely used in vessels, is one of them. It broadcasts information such as type of ship, identity number, state, destination, estimated time of arrival (ETA), location, speed, direction, cargo. In this study, to aid operators while sailin...
Damage detection in a sandwich composite beam using wavelet transforms Dawood, TA; Shenoi, RA; Veres, SM; Şahin, Melin; Gunning, MJ (2003-01-01) There is a growing interest in developing non-destructive damage detection methods for damage assessment of composite structures, especially in the aerospace and marine industries. Although damage detection of composite laminates has been widely investigated, little work has been carried out on sandwich composite configurations. A technique using the Lipschitz exponent, which is estimated by wavelet transforms, as a damage sensitive signal feature is outlined here to identify damage in sandwich composites. ...
Trajectory optimization of a tactical missile by using genetic algorithm Özdil, Baran Dilan; Kutay, Ali Türker; Department of Aerospace Engineering (2018) In this thesis, estimation of an optimal trajectory for a tactical missile is studied. Missile guidance algorithm is developed to achieve a desired mission goal according to some performance criteria and the imposed constraints. Guidance algorithms may include trajectory optimization to shape the whole trajectory in an optimal way, so that the desired performance needs such as maximum impact velocity, minimum time-of-flight or specific crossing angles can be satisfied. By performing missile path planning, a...

Underwater target detection with hyperspectral imagery for search and rescue missions Eken, Isa Cem; Çetin, Yasemin (2018-04-19) Fast and precise target detection is an issue in underwater object detection applications such as search and rescue missions. Hyperspectral imaging could be effective in determining different elements in a region thanks to its ability to provide detailed spectral information. Utilization of this rich spectral information calls for the analysis of spectral differences of objects on water surface (dry/wet) and underwater conditions. In our study, we investigated the effect of water column to the target spectr...
