An Eulerian multiphase frost model based on heat transfer measurements
(Elsevier, 2023-12-01)
In this paper, a laminar numerical model is developed to predict frost formation over a horizontal cold flat surface. An Eulerian-Eulerian multiphase approach is followed to model humid air and ice phases separately. Frost ...
Microstructural examination of black seawater mixed sulfate-resistant cement concrete
(ASCE, 2024-01-01)
The use of seawater as the mix water has been thought to be inevitable for the near future as a result of increasing water scarcity. Hundreds of papers related to seawater mixed cement-based materials were published in ...
Automated flow rate control of extrusion for 3D concrete printing incorporating rheological parameters
(Elsevier, 2024-04)
The use of inline quality assessment technologies is of great importance in meeting the consistent extrusion requirements of 3D concrete printing (3DCP) applications. This paper presents a system to regulate extrusion speed ...
Topology optimization-based design and development of a compact actuator with a high torque-to-weight ratio for quadrupeds
(IEEE, 2022)
This paper presents the design, development, and testing procedures for a compact actuator with a high torque-to-weight ratio, generally aimed to actuate legged robots, e.g., quadrupeds. The main goal of designing the ...
Design and development of a torsion-based series elastic actuator with nested encoders for a wearable exoskeleton robot
(IEEE, 2022)
This paper presents the design of a high torque-to-mass ratio series elastic actuator (SEA) for wearable powered exoskeletons. Nonbackdrivable actuators are ideal for applications that require high torque. Commonly, active ...
Numerical analysis of solar radiation effects at indoors with internal partitions and external solar shades
(International Solar Energy Society, 2020)
A numerical study is conducted to couple natural convection in an office space with thermal radiation due to solar radiation. The study specifically investigates the effect of partitions located between desks of the office ...
Rapid heating and cooling chamber for a photonics junction measurement system
(IEEE, 2020)
Since many industrial applications require heat treatment processes or validation tests under certain ambient temperatures, thermal design is a key issue to be considered in order to ensure fast heating and cooling ...
A high-torque density compliant actuator design for physical robot environment interaction
(IEEE, 2020)
Compared to the traditional industrial robots that use rigid actuators, the advanced robotic systems are mobile and physically interact with unknown and dynamic environments. Therefore, they need intrinsically safe and ...
