The precise placement of single-walled carbon nanotubes (SWNTs) in device configurations has been accomplished by AC dielectrophoresis using a biomimetic surfactant, dioctyl sodium sulfosuccinate (i.e. AOT) dispersed SWNTs. To better serve the utilization of SWNTs/AOT for device fabrication, the dispersion of SWNTs in AOT aqueous solutions was investigated at different micellar concentrations a...

The Stokes problem describes flow of an incompressible constant-viscosity fluid when the Reynolds number is small so that inertial and transient-time effects are negligible. The numerical solution of the Stokes problem requires special care, since classical finite element discretization schemes, such as piecewise linear interpolation for both the velocity and the pressure, fail to perform. Even...

This paper presents a recursive query language solution for the shortest path problem based on the transformation of a cyclic geometric graph into an acyclic time graph, i.e. an acyclic Petri Net specifying the possible transitions (turns) between successive rides on different roads. Using this transformation, the shortest path problem is transformed into a fastest tour problem. The time comple...

Displacing an object with a hand-held rod provided a simple paradigm for studying tool use. The authors asked how reaching was affected by manipulations of rod properties. Adults held a rod (length =.10 to 1.5 m), with its tip in the air; walked toward an object on a table; chose a place to stop; and displaced the object with the rod's tip. In 3 experiments (Ns = 9, 22, and 17 participants), th...

India is a large country, and highways are essential to the nation's progress. National have total distance of 70,548 km, cover 2% India's road network, handle 40% traffic. The number vehicles on increasing as population rises. As increases, accidents also increases. So, they be safe against accidents. cause for generated from accident information GIS platform redesigning highway geometrics mit...

In this work, we present firstly a study based on the calculation of the local spin densities of radical cations, which is known as a good measure of reactivity for coupling reactions, to obtain a theoretical basis for the one-step formation of poly(3.6-carbazole) and derivatives. Then we detail a DFT theoretical study of the geometric and electronic properties of oligomers based on carbazole a...

This numerical study reports the aerodynamic properties of a hybrid airship. The airships were designed by combining two semi-ellipsoids with semi-discoid as base model. From model, three different geometrics identified to their characteristics. A circular slot was provided between pressure side and suction objective this realize flow behavior, characteristics, stability such slotted flying veh...

One of the primary objectives transportation engineering is to increase safety road infrastructure. This study seeks determine relationship between geometric design parameters in relation accident criteria based on hotspots Jordan’s Desert Highway. The data (from 2016 2019) were collected from Jordan Traffic Department. spatial pattern was identified using a GIS tool named Getis-Ord Gi* severit...

INVESTIGATING THE RELATIONSHIP BETWEEN LATENT DRIVING PATTERNS AND TRAFFIC SAFETY USING SMARTPHONE-BASED MOBILE SENSOR DATA Kenneth Wynne Old Dominion University, 2016 Director: Dr. Rajesh Paleti Crash frequency modelling has been used in the past as an attempt to quantify the expected number of crashes occurring on a certain segment of roadway given a set of variables and factors describing th...
