by far, different models for determining the relationship between the flow rate  and amount of precipitation have been developed. many models are based on regression models with limited assumptions. one of the most common methods for estimating  sediment of rivers is sediment rating curve. for better estimation of the amount of sediment based of sediment curve  rating equation, it is possible t...

We exploit theoretically a magneto-controlled nonlinear optical material which contains ferromagnetic nanoparticles with a non-magnetic metallic nonlinear shell in a host fluid. Such an optical material can have anisotropic linear and nonlinear optical properties and a giant enhancement of nonlinearity, as well as an attractive figure of merit.

We present an extension of Logic Programming LP which in addition to ordi nary LP clauses also includes integrity constraints explicit representation of disjunction in the bodies of clauses and in goals and suspension of atoms as in concurrent logic languages The resulting framework aims to unify Constraint Logic Programming CLP Abductive Logic Programming ALP and Semantic Query Optimisation SQ...

A torsion pendulum without a torsion wire has been designed and realized, in order to measure very weak forces. The arm of this torsion pendulum ~5.40 g, 1.32310 kg m of inertia! is electrostatically suspended. Its 6 degrees of freedom are controlled thanks to electrostatic forces, and capacitive position sensing with a noise spectral density between 10 and 10 m/AHz. The torque noise spectral d...

Mobile manipulators have been given extensive attention in recent years since they have many applications such as materials transport and service for disabled persons. A mobile modular manipulator is normally composed of an m-wheeled mobile platform and an n-degree-of-freedom (DOF) onboard modular manipulator. This combination extends the workspace of the entire robot dramatically. Building up ...

One of the unresolved issues of the European Water Framework Directive is the unavailability of realistic water reference materials for the organic priority pollutants at low nanogram-per-liter concentrations. In the present study, three different types of ready-to-use water test materials were developed for polycyclic aromatic hydrocarbons (PAHs), polybrominated diphenyl ethers (PBDEs) and tri...

modeling and wrench feasible workspace analysis of a spatial cable suspended robots is presented. a six-cable spatial cable robot is used the same as stewart robots. due to slow motion of the robot we suppose the motion as pseudostatic and kinetostatic modeling is performed. various workspaces are defined and the results of simulation are presented on the basis of various workspaces and applied...

in the paper a model to predict the concentrations of particulate matter pm10, pm2.5, so2, no, co and o3 for a chosen number of hours forward is proposed. the method requires historical data for a large number of points in time, particularly weather forecast data, actual weather data and pollution data. the idea is that by matching forecast data with similar forecast data in the historical data...

As we enter a new millennium, society is faced with fresh challenges in every conceivable area. Through the speciality of forensic odontology, dentistry plays a small but significant role in identification of individuals. Cryogenic Grinding is the act of cooling or chilling a material and then reducing it to a small particle size. DNA is extracted from human teeth with the help of cryogenic gri...
