Effects of Different Types of Sulphates and Concentrations on Steel

Steel which is indispensable in infrastructures, transportation and manufacturing has a major drawback which is its susceptibility to deterioration corrosion that causes economic damage. Some structural failures cannot be unconnected to steel deterioration. Different factors cause deterioration of steel and steel structures but less attention has been given to the sulphate attack based on surrounding environment as one of the factors. In this work, the effects of different types of sulphates and different concentrations of sulphate solutions on the physical properties of steel over a period of time were considered. The sulphates include Calcium sulphate CaSO4 , Ammonium sulphate NH4 2SO4 , Sodium sulphate Na2SO4 and Magnesium sulphate MgSO4.H2O with concentrations of 1 , 3 and 5 . Weight loss analysis and physical observation were adopted to ascertain the deterioration of steel samples. Results show a progressive increase in weight loss for all the samples in the different solutions as the duration of immersion increases. With the exception of ammonium sulphate, the weight loss reduces with increasing sulphate concentration. Ammonium sulphate solution has a more significant effect on the steel samples than the other sulphate solutions. The deterioration also reflected in the colour and physical appearance of the steel samples. Hence sulphate causes deterioration in steel, therefore, appropriate precautions and prevention should be applied in constructions involving steel in a sulphate rich environment.

Diabetic Retinopathy Detection using Neural Networking

The clinical and laboratory studies states that diabetic retinopathy is the major cause of permanent blindness among the aged personalities. The problem with this disease is that there is no cure for it and the only thing we can do is to detect the disease as soon as possible in order to prevent further loss of vision. In this system we propose a CNN approach for diagnosing DR from retinal images and classifying the stages of the disease .The classification is done based on the haemorrhages, micro aneurysms present in the retinal image. We train this network using a high end graphics processor unit GPU using kaggle data set and the disease classification is done, hence we can identify the the disease and prevent the further loss of vision.

Solar Powered Water Pump with Improved Efficiency

In this paper it deals with speed sensor less induction motor drive with improved efficiency. A solar PV array is used for water pumping using IMD. In order to increase the efficiency and reduce the cost many sensors are eliminated. Also an additional boost converter that is used to increase the voltage from PV. Rotor flux oriented control is used for speed estimation in stationary reference frame. The proposed system is simulated in MATLAB Simulink environment.

Overview of Data Mining

Data mining is the process of discovering patterns in large data sets involving methods at the intersection of machine learning, statistics, and database systems. 1 Data mining is an interdisciplinary sub field of computer science and statistics with an overall goal to extract from a data set and transform the information into a comprehensible structure for further use. 1 2 3 4 The process of digging through data to discover hidden connections and predict future trends has a long history. Sometimes referred to as 'knowledge discovery' in databases, the term data mining wasn't coined until the 1990s. What was old is new again, as data mining technology keeps evolving to keep pace with the limitless potential of big data and affordable computing power. Over the last decade, advances in processing power and speed have enabled us to move beyond manual, tedious and time consuming practices to quick, easy and automated data analysis. The more complex the data sets collected, the more potential there is to uncover relevant insights.

Managing Cloud Data Integrity and Access Control Mechanism through Blockchain

Ever since the introduction of the internet platform there has been a significant increase in the number of services that utilize the internet paradigm. one such service is the cloud storage platform. The cloud is a collection of a large number of services that leverage the internet platform to provide users with increased convenience for performing day to day activities. The cloud storage platform is an innovative concept that allows the user to store their data on the cloud platform to enable increased convenience for the users as the data can be accessed on any device with just an internet connection. But the problem arises when the data is supposed to be accessed by several entities such as the cloud admin along with the auditors and other users while maintaining the security of the data stored. Therefore, there is a need for an efficient and secure access control mechanism that needs to be implemented on the cloud storage platform. The proposed methodology in this publication implements Reverse Circle Cipher along with the introduction of the Blockchain Distributed platform for the creation of an effective access control and integrity management technique on the cloud storage platform.

Design and Fabrication of Ground Station Antenna

As the communication technology is thriving day by day, the number of satellites are shooting up in a faster rate. The use of smaller satellites for Education, Scientific and Commercial purposes are usually positioned in LEO Low Earth Orbit flights and typically their short periods of crossing across the Line Of Sight of an Earth Station brings the need of finding ways of expanding the communication between ground and space segments. This paper elucidates the aspects related to the design and implementation of a Ground station using a directional antenna for tracking satellites which utilizes UHF band for payload transmission. First the design parameters are enumerated using Yagi Calculator Software. For verification feasibility an Electro magnetic model of an antenna is developed using ANSYS HFSS software. The procured results demonstrate some important paramount aspects of the antenna model. Finally, the “Off Shelf” components are integrated and after successful testing of hardware and software is done, it can be further extended for commercial tracking.
