Drill string nonlinear vibrations: Experimental studies and finite-element analysis
(
Institute of Physics Publishing
, 2018 , Conference Paper)
In the present work, nonlinear vibrations of drill strings are studied. A laboratory scale arrangement consisting of a flexible rod with rotor-stator system is used to study the system dynamics. A finite-element model has ...
Simulation based particle swarm optimization of cross-training policies in spare parts supply systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
We study a single location supply system for repairable spare parts. The system consists of a multi-server repair shop and inventory with ready-to-use spare parts. When a failed part is received, a new (or as-good-as-new) ...
Attitudes of heads of education and directors of research towards the need for social robotics education in universities
(
Springer Verlag
, 2018 , Conference Paper)
We explored the attitudes of the Heads of Education and the Directors of Research towards the need for Social Robotics Courses in Finland. The methods consisted of a cross-sectional survey (n = 21) and data was analyzed ...
Effect of high pass filtering of the regenerated reference signal in a single channel active noise control system
(
International Institute of Acoustics and Vibration, IIAV
, 2018 , Conference Paper)
An acoustic noise cancellation (ANC) system with regenerative feedback synthesizes its own reference signal based on the error signal and the adaptive filter output. The prime objective of such a configuration is to estimate ...
Effect of reflective surface on the impulse response of the secondary path of an active noise control system
(
International Institute of Acoustics and Vibration, IIAV
, 2018 , Conference Paper)
Previous research has shown that a reflective surface has an impact on the control performance of an active noise control system. System identification of the secondary path is of utmost importance in the effectiveness of ...
Modeling prepositioning of resources for humanitarian logistics
(
IEOM Society
, 2018 , Conference Paper)
Prepositioning of resources for humanitarian assistance to the victims of natural disaster is an important consideration to mitigate the problem that occurs due to the shortage in the supply of resources. Prepositioned ...
Sequence-Based Simulation Optimization: An Application to Container Terminals
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
This paper presents a novel method for simulation-optimization that incorporates the sequence in which the decision variables (resource levels) are optimized. The authors hypothesize that implementing such a sequence will ...
Uniform fractional factorial design tables for energy piles with maximum thermal conductance
(
WITPress
, 2017 , Conference Paper)
Energy Piles are the heat exchangers of Ground Source Heat Pumps (GSHP) that transfer the buildings heat to the lower temperature shallow ground reducing the energy consumption in the cooling of buildings. These piles are ...
A PSO approach for robust aircraft routing
(
IEEE Computer Society
, 2016 , Conference Paper)
To mitigate the impact of unpredictable disruptions, airlines are seeking to proactively design schedules that incorporate some robustness features. In this paper, we propose a novel simulation-optimization approach using ...
Experimental investigation of the laminar flame speeds of GTL fuel blends
(
American Institute of Aeronautics and Astronautics Inc, AIAA
, 2016 , Conference Paper)
This work investigates the laminar flame speed of GTL fuel and its 50%-50% blend with conventional diesel, in a cylindrical bomb capable of measuring laminar flame speed, SN, at different initial temperatures and equivalence ...
