    The image taken by a satellite can be enhanced in terms of its resolution based on the interpolation can be obtained by DWT. Using DWT, the image at the input is divided into several sub bands and the speckle noise is also removed. Thereafter, the high-level images and low-level image at the input can be combined, to produce a better image applying IDWT. An intermediate stage for approximating high level is proposed here. The variation in detection approaches for SAR images are done by using image fusion strategy and novel fuzzy clustering algorithm. To retrieve an enhanced image, wavelet fusion directives are considered to combine the wavelet coefficients. A fuzzy C-means algorithm is proposed for identifying the altered and unaltered regions in the combined difference image

    In this project we have to study of landslide, it occurs naturally we can’t stop natural cause but we can alert the people. Due to landslide there will losses of human life and properties. This project present landslide alert system by using wireless sensors that transmitted by zigbee module from this we can alert the people. In this we used three sensors accelerometer sensor, water level sensor, temperature sensor. Accelerometer sensor is used to measure the slop of angle if there is any movement in landslide and we used water level sensor to collect the depth of water in land. Temperature sensor is used to check the change in temperature. This data is given to microcontroller it is used to read the measurement and display on LCD. GPS is used to give latitude and longitude all reading is given to transmitter zigbee. This information is transmitting to receiver zigbee which is display on LCD and buzzer will activate due to this we can alert people and save human life and properties. This is real time project to save the human life

    Secure Image Transmission Using Stochastic Diffusion

    Proposed paper is methodical study of a method called Stochastic Diffusion for efficient encrypting digital images and hiding the information in another image or image set. The paper recommends efficient algorithm and mathematical model. This algorithm satisfies imperceptibility and robustness requirements. A secret key is used to securely embed the message text in the image and securely transfer the image over the network and the safely retrieve the original message text. There are two methods to implement the approach are considered. The first method uses binary image watermarking algorithm .This method is used for hiding an image in a single host image in which binarization is used for encrypted data. The second used to solving the problem of 24-bit image hiding in three host image which recovers original data after decryption. Both method are implemented using ‘hidden code’ technique.

    In the territory of agriculture, proper use of irrigation is important and it is well known that irrigation by drip approach is very cost effective and efficient.Role of agriculture in the development of agricultural country is very important. The freshly come up wireless sensor network (WSN) technology has growing rapidly into distinct multi-disciplinary fields. Agriculture and farming is one of the management which have freshly switch their consideration to WSN, curious this cost adequate technology to improve its production and boost agriculture yield definitive. The outlook of this paper is to design and develop an agricultural monitoring system using wireless sensor network and IOT to enlarge the productivity and quality of farming without penetrating it for all the time manually. Temperature, humidity and water levels are the most important circumstances for the productivity, growth, and quality of plants in agriculture. The temperature, humidity and water level sensors are set up to cluster the temperature and humidity values. One of the most stimulating fields having an exotic need of decision support systems is Precision Agriculture (PA). Through sensor networks, agriculture can be associated to the IoT, with the help of this approach which provides real-time information about the lands and crops that will help farmers make right decisions. The primary influence is implementation of WSN in Precision Agriculture (PA) with the help of IoT which will enhance the usage of water, fertilizers while expand the yield of the crops and also notifications are sent to farmers mobile periodically. The farmers can able to monitor the field conditions from anywhere

    Analysis of Balanced Stiffness Valve by using Transient Finite Element Analysis

    Get PDF
    In chemical industries there is necessary to control the flow of liquids between chambers, where it is necessary that valve will be opened when a certain pressure of fluid is reached. To control this fluid flow electronically actuated valves are generally used. Sometimes there is also need of mechanical actuated valve. A single valve will connect three chambers and will control inter flow between these chambers using a balanced stiffness approach where in flow will switch automatically operating at pressure. This paper basically focused on the transient finite element analysis of Balanced Stiffness valve. This transient analysis is generally used to determine the dynamic response of a structure under the action of any general time-dependent loads. It is used to determine the time-varying displacements, stresses, strains, and forces in valve parts as it responds to any transient loads. Here performance of the Balanced Stiffness Valve, i.e. movement of pressure plates observed. Pressure Plate area is exposing to the fluid flow instantaneously as the supply pressure given to pressure plate. Hence it is essential to examine time dependent dynamic response of the valv

    Face recognition is a process used to identify or verify the person based on digital image from unique face of humans. Face recognition is based on individual and unique person identification. This process fully based on comparing the image with other person image for identification. Face Recognition is typically used in security systems and can be compared with other biometrics such as fingerprint or iris recognition systems. Here, the major problem is to identify twins. To overcome this problem we can use different facial recognition algorithms. The facial recognition algorithms should be able to identify the similar-looking individuals or identical Twins with accurate classification. In the proposed system, image of a person is given as a input then different features of image were extracted by using the Gabor and LBP algorithms. Extracted Features of both the images are compared and then classified using multi-SVM classifier. Based on classification method, the persons were identified to be identical twins or they were identified to be same person or not twins. After Identification, Performance of the process is measured

    In the material strength test, stress and strain rate are often required to be constant. For example, during the cement quality inspection, the loading rate is required to be2.4 ± 0.2KN/S [1]; when measuring the upper and lower yielding points of metallic materials, the stain rate should stay between 0.00025/S and 0.0025/S; In the determination of elongation at break, the stress rate should stay in the range of 1-10N/mm2 S-1 when the elasticity modulus smaller than 150000 N/mm2 [2]. Since 1950s, Material Testing Machines, which adopted large-flow electro-hydraulic servo, valve to form control system, have appeared in developed countries. Control system of this type could meet the requirements for the stress and strain rate in the material strength test. For example, MTS and Instron from USA, Schench from German, and Shimadzu from Japan all adopted this type of system. With the improvement of the manufacturing level of proportional valve and the development of control technology, electro-hydraulic proportional valve began to be used as the main control part home and abroad [4]. However, this type of parts, which is vulnerable to pollution, requires medium of high cleanliness. It is of large noise and high price. This type of system could go wrong easily for the complex hydraulic system DOI: 10.17762/ijritcc2321-8169.15017
