RISModeling Flexibility in Myosin V Using a Multiscale Articulated Multi Rigid Body Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a multiscale dynamic model for the simulation and analysis of flexibility in myosin V. A 3D finite segment model, a multirigid body model connected with torsional springs, is developed to mechanically ...
Chemical Characterization of Recycling Agents
Publisher: ASCE
Abstract: Modification of aged binders by the use of recycling agents is significantly influenced by the chemical compositions of these agents. Despite the widespread use of recycling agents, the effect of their chemical properties ...
Development of Landslide Fragility Functions for Natural Gas Transmission Pipelines
Publisher: ASCE
Abstract: Natural gas transmission pipelines are at risk of failure when they traverse potential landslide regions, leading to significant service disruptions and environmental impacts. This paper presents the results of an analytical ...
Asphalt Binder Laboratory Short-Term Aging: Effective Parameters and New Protocol for Testing
Publisher: ASCE
Abstract: This work addresses the effect of time, temperature, airflow rate, and weight of asphalt binder on the laboratory short-term aging of asphalt binders and proposes an alternative protocol that can reduce the aging time and ...
Effect of Softening Additives on the Moisture Susceptibility of Recycled Bituminous Materials Using Chemical-Mechanical-Imaging Methods
Publisher: American Society of Civil Engineers
Abstract: This study examined the effects of softening additives on the moisture susceptibility of recycled bituminous materials using chemical, mechanical, and imaging laboratory investigation methods. Two chemically different ...
Effect of Recycling Agents on the Resistance of Asphalt Binders to Cracking and Moisture Damage
Publisher: ASCE
Abstract: This study examined the effect of five chemically different recycling agents on the long-term performance and moisture sensitivity of modified aged asphalt binder. A control base binder was made from 35% virgin binder and ...
Stripping Potential of HMA and SMA: A Study Using Statistical Approach
Publisher: American Society of Civil Engineers
Abstract: This study was carried out to compare the moisture resistance of two types of mixtures [i.e., hot mix asphalt (HMA) and stone matrix asphalt (SMA)]. To achieve this purpose, three dense and three gap-graded aggregates were ...
Storm Water Pollution Source Identification in Washington, DC, Using Bayesian Chemical Mass Balance Modeling
Publisher: American Society of Civil Engineers
Abstract: A Bayesian chemical mass balance (CMB) model was used to identify the sources of heavy metals in a highly urbanized area at the vicinity of the Anacostia River in Washington, DC. This method uses the elemental profiles of ...
Frequency and Temperature Interactive Effects on Hot Mix Permanent Deformation Using Response Surface Methodology
Publisher: American Society of Civil Engineers
Abstract: Effects of two of the most important factors influencing permanent deformation of styrene–butadiene–styrene (SBS)-modified and unmodified asphalt—frequency and temperature as well as their interactive effects—are studied ...
Evaluation of Thin-Lift Overlay Pavement Preservation Practice: Mixture Testing, Pavement Performance, and Lifecycle Cost Analysis
Publisher: American Society of Civil Engineers
Abstract: This study examines the practice of using thin-lift overlays (25-mm-thick asphalt) that was implemented recently for Nebraska’s highways by comparing it with the state’s traditional 5-mm-thick rehabilitation practice. The ...
