Control and Monitoring of Hydro Power Plants A Review

In hydro power plants there is a main interest for the implementation of digital systems for control and monitoring replacing the conventional control systems for power, speed and voltage. As a result it is indispensable to build up mathematical models accomplished to accurately describe both dynamic and stationary behavior of the hydro plants, in order to be able to execute digital control algorithms. A significant development in stability of the system has been observed. This paper presents the comparison of simulation and modeling of the hydro power plants and performs of different control structures and algorithms.

Research on Ship Detection in Visible Remote Sensing Images

With the continuous development of remote sensing technology and satellite communication technology, the higher is the resolution of remote sensing images, and the richer is information contained in the image. How to obtain information from remote sensing images quickly and accurately is the key problem in the application of remote sensing technology. This paper introduces the automatic detection of ship targets in visible light remote sensing images, analyzes the methods and problems of target detection and semantic segmentation based on deep learning, which improves the accuracy of ship detection. Finally, this paper summarizes the short comings of the existing methods and prospects of the future research trend.

Relation between Area of Opening and Range of Splash of Testing Fluid during Hydro Testing of Knife Gate Valve

Determination of relations between various variables is necessary while designing any experiment. Various methods may be employed depending on the availability of resources at the experimental setup. However, while the experiment is being designed, it is equally important that the same is backed by

theoretical formulae. If not derived or proved already, new ones can definitely be derived using first principles. In this study, a relation between the area of opening and range of splash shall be derived. The aim of this relation shall be to get a basic comprehension of the variation in parameters in relation to the range of splash of testing fluid. The concepts of range of splash and area of opening shall be reported at the initial stage. The area of opening shall then be determined using the method of integration considering variables involved in the formulation. On obtaining an expression, a relation between the area of opening and the range of splash shall be derived. Towards the end a conclusion shall be drawn reporting the proportional relations between the variables.

Design, Performance Evaluation and Synthesis of Sulfonated Carbon Based Catalyst for Hydrolysis of Microcrystalline Cellulose

Microcrystalline cellulose can be converted into valuable products such as glucose via hydrolysis reaction at mild condition using sulfonated carbon catalyst. A sulfonated carbon material was prepared by carbonization of bamboo sawdust followed by sulfonation. Prepared catalyst was studied for its ability to catalyze microcrystalline cellulose yield via hydrolysis reaction. Three carbon based catalysts at three different temperatures 400, 450 and 500 were prepared. The sulfonated catalysts were characterized using the following analyses elemental analysis, total acid density, FT IR, SEM and XRD. Based on the above characterization results, sulfonated carbon prepared at 500 and sulfonated via ultra sonication was found to have a higher acid density that is suitable to catalyze the hydrolysis reaction. The first step in the catalyst development approach was to increase the hydrolysis reaction by employing a stronger sulfonation procedure during catalyst preparation. The total acid density obtained for sulfonated carbon catalyst at 500 was 4.16 mmol g which significantly increases glucose yield. According to the FTIR analysis the sulfonated bio char contained sulfonic, carboxylic, and phenolic groups, which are responsible for the exhibited high catalytic performance during hydrolysis of cellulose. The yield of glucose obtained was 60.5 at 149.0Â°C in 8hour reaction time.

Design and Analysis of Crane Hook with Different Materials

Cranes are industrial machines that are mainly used for materials movements in construction sites, production halls, assembly lines, storage areas, power stations and similar places. A hook is a tool consisting of a length of material that contains a portion that is curved or indented, so that this portion can be used to hold another object. In several uses, one end of the hook is pointed. They are used to transfer the materials having heavy loads. Crane hooks are liable components subjected to failure due to stress in accumulation of heavy loads. Area of cross section, material and radius of crane hook are the design parameters for crane hook. Failure of a crane hook mainly depends on three major factors i.e. dimension, material, overload. In this paper the design of the hook is done by analytical method and design is done for the different materials like forged steel and high tensile steel. After the analytical method design and modelling of hook is done in modelling software SOLIDWORKS . The modelling is done using the design calculation from the modelling the analysis of hook is done in FEA software ANSYS WORKBENCH . This result leads us to the determination of stress in existing model. By predicting the stress concentration area, the hook working life increase and reduce the failure stress.

Design and Analysis of High Performance Floating Point Arithmetic Unit

A floating point arithmetic unit designed to perform operations on floating point numbers as well as fixed point numbers. Floating point numbers can support a much wider range of values in comparison to fixed point representation. Floating Point units are mainly used in high speed objects recognition system, high performance computer systems, embedded systems and mobile applications. To represent very small values or very large values, large range is required as the integer representation is no longer appropriate to represent these numbers so these values can be represented by using floating point representation that is based on the IEEE 754 standard. The proposed floating point arithmetic unit is designed using single stage implementation. Due to single stage implementation the complex logic operations which consist of various multiple numbers of stages are converted into single stage implementation. So by using single stage implementation the time requires to reach data from input to output becomes less. The proposed unit is designed in VHDL, simulated in Questa Sim simulator and implemented on vertex 7 FPGA.
