A branch-and-price algorithm for the two-stage guillotine cutting stock problem
(
Palgrave Macmillan Ltd.
, 2013 , Article)
We investigate the two-stage guillotine two-dimensional cutting stock problem. This problem commonly arises in the industry when small rectangular items need to be cut out of large stock sheets. We propose an integer ...
Microtron Irradiation Induced Tuning of Band Gap and Photoresponse of Al-ZnO Thin Films Synthesized by mSILAR
(
Springer New York LLC
, 2016 , Article)
Al-doped polycrystalline nano ZnO (Al-ZnO) thin films with different doping concentrations were successfully prepared by the microwave-assisted successive ionic layer adsorption and reaction (mSILAR) technique. The structural ...
Well-to-wheel water footprints of conventional versus electric vehicles in the United States: A state-based comparative analysis
(
Elsevier Ltd
, 2018 , Article)
Today, increasing levels of water demand become a particularly serious challenge for many countries, especially since water is an essential element for production of transportation fuels. Unfortunately, no research efforts ...
Robust Resource Investment Problem with Time-Dependent Resource Cost and Tardiness Penalty
(
IEEE Computer Society
, 2016 , Conference Paper)
In this paper, the classical Resource Investment Problem (RIP) is extended to consider time-depended resource cost instead of time-independent resource cost. The problem is named as the Resource Investment Problem with ...
Performance evaluation of gas-power strategies for building energy conservation
(
Elsevier
, 2015 , Article)
The work provided herein involves a comparison of natural gas and hydrogen fuels for the purpose of energy conservation for buildings via alternative energy generation methodologies. A case study simulation was developed ...
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 ...
Bird strike analysis on a typical helicopter windshield with different lay-ups
(
Korean Society of Mechanical Engineers
, 2014 , Article)
In the current paper, bird strike to a typical helicopter windshield is investigated using smoothed particles hydrodynamic (SPH) finite element method. Five types of lay-ups in a windshield (single layer stretch acrylic, ...
Optimized statistical parameters of acoustic emission signals for monitoring of rolling element bearings
(
SAGE Publications Ltd
, 2016 , Article)
Acoustic emission (AE) signal generated from artificial defects in rolling element bearings are investigated using experimental measurements in this paper. Rolling element bearings are crucial parts of many machines and ...
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 ...
Anti-spoofing device for biometric fingerprint scanners
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
Biometrics is a promising technology for safeguarding the personal identity and digital information of every individual. This paper describes an easy-to-integrate and inexpensive method to improve the security of fingerprint ...
