Effect of diameter ratios on the flow-sound interaction of the straight circular finned cylinders
(2020-01-01)
Finned tubes that are widely used in heat exchangers could be susceptible to the flow-excited acoustic resonance that generates intense pressure fluctuations, which may lead to premature fatigue failure of the tubes. This ...
Design and development of a universal gripper mechanism and development of an omni-directional unmanned aerial vehicle for autonomous perching
(2020-04-01)
A novel omni-directional multi-rotor prototype with an attached gripper mechanism named the OmniRaptor is presented with the capability of landing on inclined members in a controlled, stable manner to perform construction ...
Analysis, development, and control of multi-degree-of-freedom passive haptic devices
(2020-08-01)
Stability and transparency are key design requirements in haptic devices. Replacing conventional electric motors with passive actuators such as brakes or dampers can improve both stability and transparency as passive ...
Investigation of three integrated energy systems with desalination, heat storage, thermochemical cycles and heat upgrade
(2020-09-01)
This thesis study proposes three different novel renewable energy-based multigeneration integrated systems with molten salt heat storage and desalination options where copper-chlorine (Cu-Cl) and magnesium-chlorine (Mg-Cl) ...
Proposing effective coordinate search methods for solving large-scale expensive black-box optimization problems
(2020-08-01)
In engineering and science, optimization plays a vital role in many real-world applications. In this work, several novel optimization algorithms based on Coordinate Search (CS) algorithm are proposed. CS is a gradient-free ...
Clustering analysis of lock contention fault types using run-time performance metrics for java intrinsic locks
(2022-02-01)
Locks are essential in java-based multi-threaded applications as this mechanism provides a proper solution to synchronizing shared resources. However, improper management of locks and threads can lead to contention; as a ...
Retail electric provider selection for prosumers with local distributed energy resources and plug-in electric vehicles using data mining techniques
(2021-01-01)
In a deregulated retail electricity market, the residential customers typically have the liberty to choose an electricity service plan from a list of retail electric providers (REPs) that best matches their monthly energy ...
Early detection of cyber-physical attacks in electric vehicles fast charging stations using machine learning
(2021-08-01)
In smart grids, the concept of “vehicle-to-grid” allows the electric vehicles to export power to the grid to support the electric utilities in the power distribution system’s operation. The implementation of such a concept ...
Development of a knowledge base using human experience semantic network for instructive texts
(2021-12-01)
An organized knowledge base plays a vital role in retaining knowledge. Instructive text (iText) consists of a set of instructions to accomplish a task or operation. In the case of iText, storing only entities and their ...
Reducing operational cost of an autonomous robot using combined data-driven and navigational algorithms
(2021-04-01)
Autonomous mobile robots have become an important presence in various fields of work, but are restricted by short operation times due to the limitations of their onboard energy sources. This factor bottlenecks applications ...
