Severe plastic deformation of tubular AA 6061 via equal channel angular pressing
(
Elsevier, Ltd
, 2016 , Article)
Various severe plastic deformation (SPD) processes have been developed to produce metal tubes with ultrafine grain (UFG) structures. However, most techniques are complex and limited to working with components that are short ...
Multiobjective optimization model for scheduling of construction projects under extreme weather
(
Taylor and Francis Ltd.
, 2016 , Article)
Extreme weather significantly impacts construction schedules and costs and can be a source of schedule delays and budget overruns. A multi-objective optimization model, presented herein for the scheduling of construction ...
Robust normalization protocols for multiplexed fluorescence bioimage analysis
(
BioMed Central
, 2016 , Article)
The study of mapping and interaction of co-localized proteins at a sub-cellular level is
important for understanding complex biological phenomena. One of the recent
techniques to map co-localized proteins is to use the ...
A Switched-Capacitor Submodule for Modular Multilevel HVDC Converters with DC-Fault Blocking Capability and a Reduced Number of Sensors
(
Institute of Electrical and Electronics Engineers Inc.
