Multivariate Feature Descriptor based CBIR Model to Query Large Image Databases

The content-based image retrieval (CBIR) applications have grown their popularity in the past decade with the exponential growth in the image data volumes. The social networks have aggravated the size of image data on the internet. Social network enables everyone to upload the images of one’s choice, which becomes the reason behind aggregation of millions of images on the cyber space. It’s not possible to query these large image databases with the ordinary methods. Hence there was a strong requirement of a smart and intelligent method to discover the similar images, which has been accomplished by using the machine learning methods. In this paper, the multivariate feature descriptor method has been presented to extract the required and relevant information from the large image databases. The proposed multivariate method involves the image color and texture for the purpose of image matching to the query image (also known as a reference image). The most matching entities are returned as the final results by the image extraction method. There are four methods, which involves three singular feature and one multivariate feature-based models, have been implemented. The multivariate model has been found much stable and returned the maximum accuracy under this model.

Sensorless control of BLDC Motor using Phase Looked Loop(PLL)

This paper builds up the brushless dc (BLDC) motor sensorless control framework by utilizing the stage bolted circle (PLL) at rotor position of the engine. BLDC engine is most appropriate due to high unwavering quality, high power thickness, high proficiency, minimal effort, bring down weight and low upkeep necessities because of nonappearance of brushes. The sensorless strategies depend on the scientific model of the present age condition, EMF age condition, and speed age conditions. The procedures are utilized at the rotor position are Hall sensors, Back EMF and field arranged control strategy. The PLL used to adjust for the stage deferral of back EMF's because of zero intersection technique. The rotor position is adjusted at the halt for most extreme beginning torque with no extra sensor and the data of engine execution. The PLL depends on the staging point of the rotor pivot in anti clock astute heading from 00 to 3600. The stator current is effortlessly balanced by regulating the beat width of the exchanging gadgets amid the arrangement. Subsequent to adjusting the rotor position for accomplishing the most extreme beginning torque, BLDC engine quickens from a stop up to an ostensible speed. This paper presents created a model of brushless DC engine by utilizing MATLAB/SIMULINK and execution attributes o motor.

Flow over a Rectangular Side Weir under Subcritical Conditions

A side weir is set into the side of main channel it is an overflow weir have been extensively used in hydraulic and environmental engineering application. They typically are used for water level control in canal system, diverting excess water into relief channels during floods. An example of situation of spatially varied flow is the flow over a side weir.

A Study on Factors and Decision Behaviour of Consumers with Street Vendors at Traffic Signals

It is a common feature that there are several people will surround the vehicles when they stopped at traffic signals. Some of them are beggars. But most of them are vendors trying to sell articles which will available either on the online platforms are nowhere. This marketplace is captioned as ‘The Indian Street Malls’ or The drive in malls’. The prices are also at affordable levels and quality is also relatively good. It became imperative to study the phenomenon on how would a consumer react to such scenarios and what are the parameters impacting their decisions. This study can be utilized for introduction of new products, new concepts @ This system can be used by Government and Social groups to spread messages about traffic, health, and community various other welfare programmes. This will also help these vendors improve their business and organize their business in a better way. All together this system can better be utilized for the welfare of the society at large, with a little improvisation.

Optimization of Safety Valve’s Design with the Help of Digital Prototype

This paper is presenting optimization of a valve assembly’s design. The pressure safety relief valve is the key component in any system where pressure rising could be hazardous to the safety of the workers as well as the plant. Safety valves are designed to provide protection from overpressure in steam, gas, air and liquid lines. Safety valve should be a reliable and more precise design that will be working at more accuracy. In refinery distribution sector, safety is of prime importance. Home appliance is also required pressure safety in the modern era. The key requirement of the process is to relieve this pressure rise in no time. Old technological design valves are unable to fulfill that requirement. Design and analysis of an emergency safety valve. From the data, the suitable valve is designed using FEA. In this project is focused on change old technological safety valve with new 3D prototype valve that has less equip parts, wherein it is required that flow be shut off when a certain pressure is reached.Electronic valves are available, however, the intent of this design project is have a totally mechanical system, which has an inbuilt response mechanism. The working environment is hazardous & explosive. This safety valve is an auto-regulate operating valve used as tertiary safety arrangement for critical applications.
