RISLaser Repair With Addition of Nano-WC on Microstructure and Fracture Behavior of 304 Stainless Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Precracked 304 stainless steel (304SS) compact tension (CT) specimens repaired by laser with addition of different weight fractions of nano-tungsten carbide (nano-WC) were studied to investigate the effects of nano-WC on ...
Stochastic Forecast of Construction Cost Index Using a Cointegrated Vector Autoregression Model
Publisher: American Society of Civil Engineers
Abstract: The construction cost index (CCI) has been widely used to measure the cost trend in the construction industry. The index is used as an important input when estimating construction budgets and assessing risks in resource ...
Stochastic Revenue and Cost Model for Determining a BOT Concession Period under Multiple Project Constraints
Publisher: American Society of Civil Engineers
Abstract: The concession period is an important issue in the contractual arrangement of build-operate-transfer (BOT) projects, such as highways, bridges, and tunnels. In determining the concession period, it is predominantly the ...
Fabrication of Small Pore Size Nickel Foams Using Electroless Plating of Solid State Foamed Immiscible Polymer Blends
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel fabrication process of small poresize nickel foams has been developed using electroless plating of solidstate foamed immiscible polymer blends. Ethylene acrylic acid (EAA) and polystyrene (PS) were meltblended with ...
Effect of Laser Parameters on Microstructure and Fracture Properties of Repaired Cracks with Micro/Nano Material Addition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compact tension specimens with prefabricated cracks are repaired by laser with micro/nano materials added at the crack tip. Different combinations of laser parameters, i.e., laser power, laser spot diameter and heating ...
Flow Rate Observers in the Suppression of Compressor Surge Using Active Magnetic Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Surge is a dynamic flow instability that can cause extensive damage to compressors and other components. One common challenge that many surge control methods in the literature face when implemented in industrial applications ...
Numerical Investigation on the Selection of the System Outputs for Feedback Vibration Control of a Smart Blade Section
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents the possible and effective output signals for the feedback vibration control of the smart blade section undergoing different aerodynamic conditions. Equations of motions of the smart blade section are ...
A New Numerical Method for Solving Nonlinear Fractional Fokker–Planck Differential Equations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonlinear fractional-order Fokker–Planck differential equations have been used in many physical transport problems which take place under the influence of an external force filed. Therefore, high-accuracy numerical ...
Modeling of an Electropolishing-Assisted Electroless Deposition Process for Microcellular Metal Foam Fabrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Metal foams can be fabricated through metallizing nonconductive polymer templates for better control of pore size, porosity, and interpore connectivity. However, the process suffers from a diffusion limit when the pore ...
Product Perceptual Similarity Evaluation: From Attributive Error to Human Knowledge Hierarchy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A crucial part of any recommendation system for manufactured goods is the method used to evaluate the similarity of products. However, despite being central to the performance of many online retailers, current ways of ...
