Diabetic Retinopathy Detection System from Retinal Images

Diabetes Mellitus is a disorder in metabolism of carbohydrates, and due to lack of the pancreatic hormone insulin sugars in the body are not oxidized to produce energy. Diabetic Retinopathy is a disorder of the retina resulting in impairment or vision loss. Improper blood sugar control is the main cause of diabetic retinopathy. That is the reason why early detection of retinopathy is crucial to prevent vision loss. Appearance of exudates, microaneurysms and hemorrhages are the early indications. In this study, we propose an algorithm for detection and classification of diabetic retinopathy. The proposed algorithm is based on the combination of various image processing techniques, which includes Contrast Limited Adaptive Histogram Equalization, Green channelization, Filtering and Thresholding. The objective measurements such as homogeneity, entropy, contrast, energy, dissimilarity, asm, correlation, mean and standard deviation are computed from processed images. These measurements are finally fed to Support Vector Machine and k Nearest Neighbors classifiers for classification and their results were analysed and compared.

Synchronization and Reactive Current Support of PMSG Based Wind Farm during Severe Grid Fault

Grid codes require wind farm to remain on grid and inject specific reactive current when grid fault occurs. To satisfy the requirements, reactive power devices such as the static synchronous compensator STATCOM are usually used in modern wind farms. In order to produce reactive currents, the wind energy generation system WECS and the STATCOM are normally controlled with the phase locked loop PLL oriented vector control methods. The paper is about synchronization and reactive current support of PMSG.

A Detailed Investigation and Testing of Grid Voltage Oriented Sliding Mode Control for DFIG Doubly Fed Induction Generator

Doubly Fed Induction mills DFIGs are widely utilized in variable velocity wind mills in spite of the nicely frequent overall performance of DFIGs, those mills are particularly realistic to grid faults. Therefore, the presence of grid faults ought to be taken into consideration inside the layout of any manage device to be deployed on DFIGs. Sliding Mode manage SMC is a beneficial alternative for electric powered equipment manipulate because SMC offers rapid dynamic reaction and less sensitivity to parameter versions and disturbances.

Factors Influencing Contractors Selection in Construction Projects

Contractor selection is a critical decision that is undertaken by client organizations and is central to the success of any construction project. The process should be conducted prior to the award of contract, characterized by many factors such as contactor’s skills, experience on similar projects, track record in the industry, and financial stability. Selection of the best contractor is a vital process in construction projects. This paper identifies the most important factors that influence the selection of contractors. A questionnaire was distributed to experts in the construction domain to determine the importance of factors that are taken into consideration by the main contractor to select the most suitable contractor. A survey was carried out which was conducted with many experts in the construction field to determine the score of each factor.

Effect of Coconut Shell as a Coarse Aggregates on Behavior of Concrete

The prices of building materials are rising day by day. The main ingredient of the concrete is coarse aggregate. Nowadays, many of the researchers are researching the material which can reduce the cost of construction as well as increase the cost. In developing countries, the possibility of using some agricultural wastes as well as industrial by products from different industries as construction materials will be highly desirable and has found to have several practical advantages. It was observed that the coconut shell has a great potential as a partial replacement of the aggregate in the concrete. The present work is only an accumulation of information about GFRGC and the research work which is already carried out by other researchers. Coarse aggregate were used in proportions of 5 , 10 , 15 to replace coarse aggregate in conventional concrete. The high demand for concrete in the construction using normal weight aggregates such as gravel and granite drastically reduces the natural stone deposits and this has damaged the environment there by causing ecological imbalance. This study aims in development the mix design of lightweight aggregate concrete using Coarse Shell as coarse aggregate together with cement and river sand. Coconut shell reinforced composites have been used as cheap and durable non structural elements.

Effectiveness of Online Teaching in Higher Education during Covid19 Pandemic in Mysore

As Covid19 entered the world in the beginning of 2020, India also witnessed rising number of cases as of huge population next to china. As a safety measure against Covid 19 pandemic, as per the government order, university announced holidays for the students from 16 march 2020. Colleges were shut from long time, didn’t even conduct the examination for the first and second year of UG course and first year of PG course. Only final year students appeared for the exams with so much of worry and fear. though Covid 19 started spreading rapidly educationist did not stop teaching . Teachers explored new way of teaching by learning new technology and continue to engage students during pandemic. The universities are meant for traditional teaching ,adopted to online teaching as per the guidelines of UGC. An attempt is made to study to measure the effectiveness of online teaching to university students in Mysore district. around 550 students are surveyed through Google forms and responses are analysed and presented in this paper.

Keyloggers A Malicious Attack

Keylogging, one of the unsafe malware, is the movement of recording the keys struck on a console with the end goal that the individual utilizing the console is obscure about the way that their activities are being watched. It has legitimate use in examination of human PC collaboration and is considered as the primary danger for business and individual exercises. It tends to be utilized to catch passwords and other secret data entered by means of the console. Subsequently, counteraction of keylogging is significant and severe validation is needed for it. Planning of secure confirmation conventions is very testing, taking into account that different sorts of root units dwell in Personal Computers to watch clients conduct. There are different keylogging procedures, stretching out from equipment and programming based techniques to acoustic assessment. Human contribution in confirmation conventions, however ensuring, isnt straightforward. This paper surveys different examination regions which spread convention confirmations utilized safely forestalling the representation of keylogging assaults.
