The effect of drinking water quality on the health and longevity of people-A case study in Mayang, Hunan province, China
(Peer reviewed; Chapter; Bokkapittel, 2017)
Drinking water is an important source for trace elements intake into human body. Thus, the drinking water quality has a great impact on people's health and longevity. This study aims to study the relationship between drinking water quality and human health and longevity. A longevity county Mayang in Hunan province, China was chosen as the study area. The drinking water and hair of local centenarians ...
Group Based Asymmetry – A Fast Saliency Algorithm
(Chapter; Bokkapittel, 2015-12-18)
In this paper, we propose a saliency model that makes two major changes in a latest state-of-the-art model known as group based asymmetry. First, based on the properties of the dihedral group D4 we simplify the asymmetry calculations associated with the measurement of saliency. This results is an algorithm which reduces the number of calculations by at-least half that makes it the fastest among the ...
The Compliance Challenges in Emissions Control Regulations to Reduce Air Pollution from Shipping
(Peer reviewed; Chapter; Bokkapittel, 2019-10-14)
One of the thorny problems perplexing the maritime industry is to comply with existing and soon-to-be-enacted regulations towards emissions reduction from shipping. This problem has been discussed in this study under three viewpoints: i) the marine engine efficiency, ii) the decision-making process for selecting the technologies for reducing air emissions from shipping and iii) the challenges in the ...
Trends in seismic data acquisition in areas with surface ice
(Peer reviewed; Bok; Chapter, 2019)
The Arctic has great significance in relation to the exploration and exploitation of its huge petroleum resources. Seismic surveys are the key part of petroleum exploration. Reflected sound waves are used to produce a 3D subsurface geological model, which helps to take a decision on drilling location for potential hydrocarbon resources. Seismic surveys are very complex operations, and growing energy ...
Risk Assessment of Hazards Due to the Installation and Maintenance of Onshore Wind Turbines
(Peer reviewed; Book; Chapter, 2018-06-11)
In this work, an assessment of four types of risks is carried out for wind turbines during four phases, namely: transportation, installation, operation and maintenance. This work mainly focuses on onshore type of wind turbines and briefly mentioning the offshore wind turbines. The introduction gives an overview of the main parts and components of wind turbine, in addition to discussing the process ...
An AIS-Based Multiple Trajectory Prediction Approach for Collision Avoidance in Future Vessels
(Peer reviewed; Bok; Chapter, 2019-11-11)
This study presents a method to predict the future trajectory of a target vessel using historical AIS data. The purpose of such a prediction is to aid in collision avoidance in future vessels. The method presented in this study extracts all trajectories present in an initial cluster centered about a vessel position. Features for each trajectory are then generated using Principle Component Analysis ...
Identifying hazards to include in risk analyses
(Bokkapittel; Chapter, 2018)
A risk analysis should provide decision makers with information regarding relevant hazards. The initiating phase, where the risk analysts identify hazards to be included in the risk analysis, lays the foundation for the rest of the analysis. This phase is, therefore, of great importance. In this paper, we examine how risk analysts in a municipal setting identified potential adverse events and how ...
