The objective of the research is to complete a theoretical and practical study related to coastal marine works in order to calculate the amounts of silt removal from harbor basins and entrances, and to present the methods and devices used in the performance of topographic survey and numerical methods in the calculation and comparison of quantities. In the theoretical part, the factors that lead to the formation of silt deposits in the port basins, the methods of their removal and the deepening of the navigational pathways to enter and exit the harbors were addressed. In the practical part, the results, methods of measurements and topographic results were presented during the stages of investment of the port, at least two stages, at the beginning of the investment and before the process of direct withdrawal, and then calculating the quantities of the implemented and comparing them, to obtain maritime plans and final quantities. The research concluded with specific proposals on the methods of calculating the quantities of the isolated port, the method of constructing the measured geodetic networks, the achievement of the topographic elevation under the water surface, and the identification of the software parts related to the various marine works and ways of benefiting from them.

The research aims to complete the study of the theory and operation of networks geodesic associated marine beach, whether horizontal or vertical, with display rods and devices used in completion of topographic survey of networks in both land and ma rine parts. In theoretical part it was addressed to specific shapes networks geodesic which distinguish maritime works beach that takes the form of the morphological characteristics of the natural land of each building proposed network, and the numerical characteristics of each building proposed networks. In the practical part the results of measurements and amendments was presented to some forms of executed geodesic beach networks for several forms of works: (topographic raise achievements within the existing and investor basin in order to establish a slider, completion of the cadastral beach works in order to determine distortions in the existing pier, clean the shipyard of silt and sediment. Software has been reviewed to assist in completing marine works, utmost to obtain the final marine charts. The research concluded that specific proposals on vertical geodetic networks studies, and identify the various parts of software related to marine works and ways to take advantage of them.
Hydraulic drives are able to generate high forces and move large loads. With the help of proportional valves, it is possible to control movements fast and accurately. Depending on the application, a linear cylinder, a rotary cylinder or a rotary mo tor are used. Linear cylinders are most frequently used. The following designs are therefore confined to this type of drive. We compare among various types of cylinders which are common by used. We compared different conditions for cylinders with friction and without it.
Induction motors are the most widely used electrical motors due to their reliability, low cost and robustness. However, induction motors do not inherently have the capability of variable speed operation. Due to this reason, earlier dc motors were a pplied in most of the electrical drives. But the recent developments in speed control methods of the induction motor have led to their large scale use in almost all electrical drives. Out of the several methods of speed control of an induction such as pole changing, frequency variation, variable rotor resistance, variable stator voltage, constant V/f control, slip recovery method etc, the closed loop constant V/f speed control method is most widely used. In this method, the V/f ratio is kept constant which in turn maintains the magnetizing flux constant so that the maximum torque remains unchanged. Thus, the motor is completely utilized in this method.
We develop a minimally-supervised model for spelling correction and evaluate its performance on three datasets annotated for spelling errors in Russian. The first corpus is a dataset of Russian social media data that was recently used in a shared tas k on Russian spelling correction. The other two corpora contain texts produced by learners of Russian as a foreign language. Evaluating on three diverse datasets allows for a cross-corpus comparison. We compare the performance of the minimally-supervised model to two baseline models that do not use context for candidate re-ranking, as well as to a character-level statistical machine translation system with context-based re-ranking. We show that the minimally-supervised model outperforms all of the other models. We also present an analysis of the spelling errors and discuss the difficulty of the task compared to the spelling correction problem in English.
The research aims to develop some formulas of sample size and characterization and comparison among themselves to determine the best formula of formulas to calculate the sample size and the creation of a modified reflected well on the sample size, in addition to specifying individual gratification I and II for the relevant formulas and mathematical equations can predict the sample size, however the size of the community. The researcher through the study the following results: The results were identical to the formula related to the size and the sample size when consolidation requirements. Sample size did not increase with increasing size of the moral community at first gratification. No moral differences between sample volume according to the size of the community when individual gratification. Moral differences exist between sample size and average total inspection according to the size of the community when individual gratification. We got a mathematical models of the relationship between size and the sample size and the size of the community and the average total inspection. We have developed a comprehensive table gives sample size corresponding to the size of the community can be accessible to researchers to take advantage of it and apply the formulas as long as it originally relied upon certain conditions.
