Mathematical model for thin-walled corrugated tube under axial compression
(
EDP Sciences
, 2016 , Conference Paper)
In this research, theoretical investigation of corrugated aluminum tubes is performed to predicting the energy absorption characteristics. Aim to deform plastic tubes in predetermined intervals, corrugations are introduced ...
Simulation-Based Parametric Study for the Hybrid Superplastic Forming of AZ31
(
Elsevier B.V.
, 2019 , Conference Paper)
As the lightest constructional metal on earth, magnesium alloys offer excellent potential for weight reduction in the transportation industry and it was observed that some magnesium alloys exhibit superior ductility and ...
In-depth Analysis of Pedestrian Safety in the State of Qatar
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Pedestrian safety is of a serious concern as it includes children and the aged population. From the Global status report on road safety in 2015 by World Health Organization (WHO), it can be seen that pedestrian fatalities ...
Combustion Characteristics and Emissions of a Direct-Injection Diesel Engine Fueled with GTL Fuel Blends
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Gas to Liquids (GTL) is one of clean alternative fuels which loosely defined terms that is generally used to describe the chemical conversion of natural gas to some type of liquid products. As such, it excludes the production ...
Vibration wave characteristics in Conventional and Periodic Drill string models
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Drill string models are of two major types- Conventional and Periodic. Conventional drill string models are widely used due to their simplicity in manufacturing and dynamics analysis. Drill strings are affected mainly by ...
A framework for condition-based maintenance scheduling
(
IEEE
, 2012 , Conference Paper)
This paper presents a general framework for planning and optimizing Condition-Based Maintenance scheduling. We assume that the hazard function depends, not only on time, but also on the system state which degrades over ...
Three maintenances for age replacement policies
(
International Society of Science and Applied Technologies
, 2017 , Conference Paper)
Preventive replacement policy conducted at a routine time T* has been surveyed extensively in literatures. Another two random replacement times Y1 and Y2 are jointly considered in this paper. We formulate the models of ...
Multi-sensor degradation data analysis
(
Italian Association of Chemical Engineering - AIDIC
, 2013 , Conference Paper)
Multiple sensors are commonly used for degradation monitoring of critical components. The degradation indicators derived from these sensors are significantly different in terms of scale and interpretation. Since these ...
