Position Repeatability Test for Knife Gate Valves with Electro Pneumatic Positioners

Repeatability is an important characteristic of the measurement of faithfulness of the response of a system over a period of time. Be it mechanical or electronic equipment, over a certain period of time, there is a certain amount of hysteresis that sets in which renders the system incapable of carrying out its operation with the necessary precision. In applications that employ Knife Gate Valves to control the flow of lesser demanding solid particulate media like powders and fine mixtures, it is necessary that the positioners mounted on the valves display repeatability at all values of opening in every operating cycle. At least during the serviceable life of the valve, it is imperative of the positioner to ensure that hysteresis is not set in and that the internal mechanism is capable of yielding precise results. This paper shall consider four positioners mounted to Knife Gate Valves and subject the same to a repeatability test wherein the valves will be opened to a predetermined opening percentage for two cycles. The current input readings corresponding to these percentage openings shall be noted and graphs shall be plot to understand the repeatability behaviour. The mean values of current input readings for the four positioners shall be plot to determine the reproducibility of the experiment. A conclusion shall be drawn thereafter considering the experimental observations.

Failsafe Revival Test for Knife Gate Valves with Electro Pneumatic Positioners

Processing applications work on the principle of metered flow of working media to ensure accurate execution of the processes in the further stages. These may include food or raw material processing units that are highly concerned about the quantity of flow media passing through a given section in a given period of time. Foe specific applications, higher precision is required when it comes to the percentage of opening of the flow area as the same is directly proportional to the success of the process. In such cases, special accessories called positioners are used that can position the valve trim components to a desired extent to initiate the necessary percentage opening of flow. This paper shall focus on such positioners mounted on Knife Gate Valves and their ability to deliver precision in the opening percentage. The condition considered shall be that of a failsafe revival requirement wherein during operation, if there is failure of electric power or air supply, the valve shall act according to the set failsafe condition and once the electric power or air supply is restored, the valve opens to the same opening as it was before the said failure. This can clearly demonstrate the property of precision of the positioner. In order to ensure wider applicability, four such positioners shall be considerde and an experimental procedure shall be put forward and followed accordingly. The results obtained shall be described in the form of graphs and a conclusion shall be drawn accordingly towards the end.

Adaptive Image Resizing using Edge Contrasting

Zooming is an important image processing operation. It can be termed as the process of enlarging or magnifying the image to a given factor. Indiscriminate application of a function to an image in order to resample it, produces aliasing, edge blurring. So the objective is to reduce these artifacts.This paper considers distinctive interpolation systems identified with versatile techniques with innate abilities to ensure sharp edges and subtleties. It is a versatile resampling calculation for zooming up pictures In this work, a versatile edge improvement procedure is proposed for two dimensional 2 D picture scaling application. The foreseen picture scaling calculation comprises of an edge identifier, bilinear interpolation and Sobel filter. The bilinear interpolation characterizes the power of the scaled pixel with the weighted normal of the four neighboring pixels, inserted pictures become smooth and loss of edge data. The versatile edge upgrade procedure is utilized to secure the edge includes successfully, to accomplish better picture quality and to dodge the edge data. The Sobel filter endeavors to decrease the commotion, in obscured and mutilated edges which is delivered by bilinear interpolation. A mathematical control and equipment sharing strategy are utilized to lessen registering asset of the bilinear interpolation. The examination shows that edges are very much safeguarded and interpolation artifacts obscuring, jaggies are decreased To contrast existing algorithms and proposed strategy calculation, we have taken original pictures and results for discussion. And we have gone to the choice that proposed calculation is superior to the current algorithms. We have looked at the images by two different ways – Mean Square Error MSE and Peak Signal to Noise Ratio PSNR.

A Comprehensive Review of Possibility using Solar Energy for Electricity Generation in Libya

Libya suffers from electricity shortages, and many challenges will have to be overcome to meet future increases in electrical demands. The deficiency of electricity generation in Libya is clearly manifested in the fact that demand on electricity still exceeds its supply as blackouts become more frequent. In peak demand time, blackouts and outages are the major phenomena in almost all the Libyan regions. Due to technical issues, illegal connections and throughout the lengthy civil war, the generation and transmission in addition to distribution functions suffered partial destruction and consequent outages. For all the mentioned problems, Renewable energy sources and technologies have potential to provide solutions to the long standing energy problems being faced by the Libyan electricity. Alternative renewable energy sources like solar energy technology can be an important part of Libyas plan not only to add new capacity but also to increase energy security, address environmental concerns, as well as to overcome energy shortage. Libya is very rich in solar energy resources and possesses large wasteland areas in the Sahara that represent 88 of the total area and much of this is relatively flat. Libya is one of the countries with the abundance of this type of energy, with a daily average of the sunshine reached to 8.1 kWh m2 day, and where annual solar activity more than 3500 kWh m2 year on the horizontal surface. Losses in the transmission and distribution system will be reduced since power is generated near loads. The grid availability and stability will increase and individuals can save money in their electricity bill and finally the generated power is clean and nonpolluting. This paper presents the main sources of alternative renewable energy in Libya and its potential besides the main reasons Libya is turning to alternative energy solutions to fully utilize its renewable energy resources, fulfill the energy demand in the future and to reduce the outages of electricity and carbon emissions.

Performance Based Analysis of RC Framed Structure with and without Dampers for Different Seismic Zones

The primary requirement of humans on planet earth is food, clothing and shelter. Prehistoric men and women used to live on trees but steadily they started developing the shelters for protection against natural calamities like rains, cold etc. and also from attack against wild animals. Soon humans grew in knowledge and they started living together, forming communities to ensure additional security and man became a social animal. Now these communities developed and started exploding forming villages which later on transformed into cities and became the commercial centres of a region. Soon within these commercial centres, land for horizontal expansion became extinct. The social animal started expanding vertically constructing multi storied structures. The present study focuses on 12 levelled multi storey structure. The structures are considered to be located at various seismic zones. The Performance of the structure is found out by static nonlinear structure. Further, these structures are provided with seismic dampers. The Modelling and analysis are carried out using ETABS software. The performance of these structures is studied and compared using various parameters such as displacement, storey drift, base shear and time period. Along with these results performance of building is predicted based on demand capacity graphs. The results are extracted and conclusions are drawn.From the pushover analysis, the performance point is found out for all the models. And also, it found that, weakest junctions of the models. The Pushover analysis shows the models with dampers are having base shear than the models without damper. The increase in percentage of base shear is around 45 . The introduction of damper causes the improvement in lateral load carrying capacity by 45 . The base shear values are lesser for Zone II and highest for Zone V. There is a linear increase in base shear values for increase in severity of zones. From the pushover analysis base shear, it is noticed that all the models are having lesser base shear values in case of equivalent static analysis than pushover analysis except Model type A4. This shows that, the model Type A4 is UNSAFE. The models can be made SAFE by introducing Dampers as in Models Type B4.
