An efficient path planning algorithm for general 6 degrees of freedom robots is presented in the paper. The path planner is based on multiheuristic A search algorithm with dynamic subgoal generation for rapid escaping from deep local-minimum wells. The algorithm has been implemented as an extension to a robot off-line programming and simulation system for testing. The presented test results dem...

We propose semi-random features for nonlinear function approximation. The flexibility of semirandom feature lies between the fully adjustable units in deep learning and the random features used in kernel methods. For one hidden layer models with semi-random features, we prove with no unrealistic assumptions that the model classes contain an arbitrarily good function as the width increases (univ...

Scale and corrosion control are big challenges in utilizing geothermal energy. In the production wells, during or after flashing, brineresults in higher pH, which can happen deep inside the well.Higher pH in combination with high temperature causes calcium carbonate precipitation. Silica/Silicate precipitation becomes a problem when the brine gets cold in the surface equipment and the rejection...

To the Editor, The Indian Medical Gazette. Sir,?I was very interested to see the article by mv old friend and brother-officer Lieut -Col. G. G. Jollv who is now Director of Public Health in Burma, in your last issue. His article gives an interesting account of a very common occurrence in connection with deep wells. He observes that under certain climatic conditions there is a decided falling of...

a new comer. The border districts are Nepal on the north, Bhagalpur on the west, Dinajpur on the east and Sonthal Parganas on the south. The water supply is mainly from shallow wells, 10 to 12 feet deep. Small hilly rivers intersect the district every where. There is abundant rainfall and great humidity of the atmosphere. The disease occurs in Purnea in sporadic form and except in three instanc...

A shallow acid assemblage of sulfur and kaolinite +/alunite, dlclate and pyrophyllite dominates the hydrothermal alteration in the seven wells in Cawayan from surface down to 0 mRL. These zones range in thickness from 20 to 220 m. Thts shallow acid zone formed at temperatures < 160°C. Below 0 mFU down to -600 mRL, a deep acid zone of dlaspore and pyrophyllite +/alunite and dlclute appear in thi...

The discrete time path integral Monte Carlo with a one-particle density matrix approximation is applied to study the quantum phase transition in the coupled double-well chain. To improve the convergence properties, the exact action for a single particle in a double-well potential is used to construct the many-particle action. The algorithm is applied to the interacting quantum double-well chain...

We present a method that allows us to the find asymptotic form of various X characteristics of disordered systems in the strong localization regime, i.e., when either the random potential is big enough or the energy is close enough to the spectrum edges. The method is based on the hypothesis that relevant realizations of the random potential in the strong localization regime have the form of de...

It presents a systematic methodology to evaluate the reservoir characteristics of ChipilapaAhuachapan geothermal field through the highly diluted natural manifestations (springs and domestic wells) in its surroundings. The manifestations are classified in three main groups according to their mechanism of formation: high salinity water (HSW), medium salinity water (MSW), and Sulfated Water (SW)....
