Determining the awareness and knowledge of officers towards ship energy efficiency measures
(Faculty of Maritime Studies, 2021)
Improving energy efficiency practices on ships is crucial for both economic and environmental purposes. Both technical and operational applications are made to increase energy efficiency on ships. The success of energy ...
A new integrated grey mcdm model: Case of warehouse location selection
(Faculty of Mechanical Engineering, 2021)
Warehouses link suppliers and customers throughout the entire supply chain. The location of the warehouse has a significant impact on the logistics process. Even though all other warehouse activities are successful, if the ...
Management tools for implementation and monitoring of requirements for enforcement of reducing sulphur oxides on ships: Latvia and Lithuania cases
(Naval Academy Publishing House, 2021)
The main type of bunker oil for ships is heavy fuel oil, derived as а residue from crude oil distillation. Crude oil contains sulphur which, following combustion in the engine, ends up in ship emissions. Sulphur oxides ...
Selection of welding conditions for minimizing the residual stresses and deformations during hard-facing of mild steel
(Brodarski Institute, 2021)
Hard-facing process is widely used for improving the wear resistance of mild steel. During the application of hard-facing, due to high temperatures, residual stresses and deformations may occur. The tensile residual stresses ...
On a recursively defined sequence involving the prime counting function
(University of Waterloo, 2021)
We prove some properties of sequence A335294 from the On-Line Encyclopedia of Integer Sequences, defined by an = ?(n) - ?(?n-1 k=1ak), where ?(x) is the number of primes ? x. In particular we show that the sequence (an) ...
INVESTIGATING THE THERMAL AND STRUCTURAL RESPONSES IN HARD-FACING APPLICATION WITH THE GTAW PROCESS
(Institute of Mechanics, 2021)
The gas tungsten arc welding (GTAW) process is an excellent way of performing quality hard-facing applications. The residual stresses and distortions are encountered in hard-facing. There are several methods to decrease ...
Modeling, Simulation and Analysis of Bipolar Driven BLDC Motor
(Institute of Electrical and Electronics Engineers Inc., 2021)
This article reviews modeling, simulation, and performance of a bipolar driven BLDC motor. The study aims to contribute to the performance analysis of the motor by suggesting a detailed model of the considered BLDC motor ...
Monolithic characters of real groups
(Taylor & Francis Inc, 2021)
In this article, we are concerned with the nonlinear primitive and monolithic characters of a finite real group. We give some criteria for determining whether or not a finite group is real by using its monolithic characters. ...
Data-Driven Generative Design Integrated with Hybrid Additive Subtractive Manufacturing (HASM) for Smart Cities
(Springer, 2021)
Generation of smart cities that considers environmental pollution, waste management, energy consumption and human activities has become more important in recent years since it was first introduced in the 1990s. In the smart ...
Applying reverse engineering principles on analysis of failures occurred in ship production
(Society of Naval Architects and Marine Engineers, 2021)
In the current work, a new error evaluation methodology is introduced based on error analysis in ship production with reverse engineering data. The aim is to determine the errors and prevent or reduce the occurrence in ...
