RISAspect Ratio Effects on Turbulent and Transitional Flow in Rectangular Microchannels as Measured With MicroPIV
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microscopic particle image velocimetry (microPIV) was used to measure velocities in rectangular microchannels with aspect ratios ranging from 0.97 to 5.69 for 200<Re<3267. Mean velocity ...
Adaptive Dynamic Surface Based Nonsingular Fast Terminal Sliding Mode Control for Semistrict Feedback System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper focuses on an adaptive dynamic surface based nonsingular fast terminal sliding mode control (ADS-NFTSMC) for a class of nth-order uncertain nonlinear systems in semistrict feedback ...
Design of a Passive Controllable Negative Modulus Metamaterial With a Split Hollow Sphere of Multiple Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a passive controllable negative modulus metamaterial based on a split hollow sphere (SHS) with multiple holes. The metamaterial is obtained by changing the number of split holes. The experimental results show ...
Supplier Selection and Order Allocation Research on Purchasing Management in Supply Chain Enterprises under the Total Just-in-Time Environment

Pulsed Power Supply Superposed With Radio Frequency Oscillating Wave for the Improvement of Micro-Electrical Discharge Machining Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the micro-electrical discharge machining (micro-EDM) process, the dielectric property of narrow interelectrode gap is transiently changing. With the hysteretic servomotion of spindle, the effective discharge ratio ...
Short Landing Performance and Scale Effect of a Flapping Wing Aircraft
Publisher: ASCE
Abstract: An investigation was made into the performance and scale effect of birdlike flapping wing aircraft in short landing. A flapping mechanism is proposed to transform a powered shaft rotation to an optimal kinematics of wing ...
Behavior of Saturated Remolded Loess Subjected to Coupled Change of the Magnitude and Direction of Principal Stress
Publisher: American Society of Civil Engineers
Abstract: Undrained torsional shear tests were carried out on remolded loess specimens using a hollow cylinder apparatus to investigate the deformation behavior and noncoaxiality (where the direction of the plastic strain increment ...
Experimental Investigation on the Performance of Cement Mortar by Partial Replacement of the Standard Sands with Sulfide-Contained Iron Tailings
Publisher: ASCE
Abstract: The usage of iron tailings as construction aggregates is a potential route to save the cost of standard sands and protect the environment of mining area. This study mainly investigates the performance of cement mortars by ...
Subcritical Debonding Characterization of GFRP-Concrete Bonded Interface Using Modified Single Cantilever Beam Specimens
Publisher: ASCE
Abstract: Subcritical debonding of glass fiber reinforced polymer (GFRP)-concrete bonded interface in both the air (room environment) and water is characterized using the modified single cantilever beam specimens. A modified specimen ...
Long-Term Water Stability of Hydraulic Asphalt Concrete Based on Time–Temperature Equivalence
