Semi-geostrophic dynamics of jets are studied using a potential vorticity front in an equivalent barotropic model. Meandering processes of the front are examined in the thin-jet limit on a β-plane by a curvilinear coordinate system. For calculated along-front velocity fields, asymmetrical profiles are caused by meandering. This asymmetry of the velocity profile is enhanced as the Rossby number ...

In this paper, an unscented Kalman filter (UKF) for curvilinear motions in an interacting multiple model (IMM) algorithm to track a maneuvering vehicle on a road is investigated. Driving patterns of vehicles on a road are modeled as stochastic hybrid systems. In order to track the maneuvering vehicles, two kinematic models are derived: A constant velocity model for linear motions and a constant...

Based on the fully nonlinear Boussinesq equations in Cartesian coordinates, the equations in generalized coordinates are derived to adapt computations to irregularly shaped shorelines, such as harbors, bays and tidal inlets, and to make computations more efficient in large near-shore regions. Contravariant components of velocity vectors are employed in the derivation instead of the normal compo...

The direct coordinate transformation method, which only transforms independent variables and retains Cartesian dependent variables, may not be an appropriate method for the purpose of simplifying the curvilinear parabolic approximation of the vector form of the wave–current equation given by Kirby [Higher-order approximations in the parabolic equation method for water waves, J. Geophys. Res. 91...

In this paper, we investigate how the form of the conventional elastodynamic equations changes under curvilinear transformations. The equations get mapped to a more general form in which the density is anisotropic and additional terms appear which couple the stress not only with the strain but also with the velocity, and the momentum gets coupled not only with the velocity but also with the str...

Background: The influence of inorganic fertilizer has posed considerable challenges on increasing food production worldwide. A careful plan is required to increase the yield and quality crops. profound knowledge use organic manure involvement in plant growth development could be beneficial for production. acceptable different concentrations vermicompost been used an attempt enhance crop with ai...

Background: Varicocele (VCL) exerts its impact via enhancing inflammation and down-regulating testicular endocrine and antioxidant statuses. Celecoxib (CCB) is a non-steroidal anti-inflammatory drug (NSAID), which its effects based on the inhibition of cyclooxygenase (COX) enzymes. On the hand, silymarin (SMN) is known for its remarkable anti-oxidative impact. Therefore, present study was desig...

The influence of cutaneous and joint receptors on the quadriceps femoris torque-velocity relationship was assessed with the Kin-Com (Chattecx, Inc., Hixson, TN) isokinetic dynamometer. Twenty-four females (age = 21 ± 1.4 years, ht = 163 + 6.0 cm, wt = 60 ± 7.6 kg) were divided into two groups and tested with the force pad placed either proximally or distally on the leg. Three concentric and ecc...

Virtual machine (VM) technology is widely used in higher education to support pedagogy and research. However, without a standard platform for managing VM technology, VM-based infrastructure is likely to be acquired and deployed in an ad-hoc manner. The virtual computing lab (VCL) system is an open source cloud computing platform developed specifically to support higher education. The main goal ...

Heterogeneous computing systems can dramatically increase the performance of parallel applications on clusters. Currently, most applications that utilize OpenCL devices (CPUs, GPUs, Accelerators), run their device-specific code only on devices of the same computer were the application runs. This paper presents the VirtualCL (VCL) cluster platform, a wrapper for OpenCL that allows most unmodifie...
