Design and Simulation Studies on Linearised MEMS Capacitive Accelerometers with different Beam Springs

admin — Thu, 25 Jul 2019 08:59:04 +0000

Abstract: Capacitive accelerometers based on change in air gap measurement often experiences non-linearity. In order to overcome this drawback, the overlapping area of the device is changed which produces linear output. In this paper, four different types of beam springs (viz. Half-folded spring, Meander spring, Serpentine spring and Zig-Zag spring) were introduced in the capacitive accelerometer structure. All the springs are subjected to different accelerations and linear outputs are obtained. The cross-axis performance of the four springs is compared. Among the four springs, Half-folded spring and Serpentine spring provide low cross-axis sensitivity. The structures are designed, analysed and simulated using IntelliSuite software.

Abstract: Internet of Things (IoT) is promising future technology is relied upon to interface billions of gadgets. Expected to deliver more correspondence Data pinnacles and information security can be a risk. This size of the gadget in this engineering is essentially little, low power utilization. Many rounds of encryption are essentially a misuse of requirements Gadget vitality. Less convoluted calculation, be that as it may, conceivable compromise required uprightness. It is a 64-bit square secret key that requires a 64-bit key to encrypt information. The engineering of the calculation is a blend of feistel and a uniform substitution – to supplant the system Simulation. The outcomes demonstrate that the calculation gives only a considerable security five rounds of encryption. The proposed work demonstrates the implementation of symmetric key lightweight algorithm for secured data transmission of images and text using image encryption system as well as reversible data hiding system. Proposed research have demonstrated faster computation, less complexity and higher PSNR as compared to existing algorithms. In the proposed work we have implemented symmetric key cryptography for various format of images, as well as real time image acquisition system has been designed in the form of graphical user interface.

Automatic Detection of Malaria Parasite from Blood Images using MATLAB

admin — Wed, 21 Aug 2019 09:39:10 +0000

Abstract: Malaria is a mortal disease caused by parasites that are transmitted to people by mosquitoes. An estimated 700,000 people were killed by malaria in 2010 globally and approximately half the world’s populations are at risk of the disease. Malaria is preventable and curable. The best way of diagnosing it is to look at samples of a patient’s blood down a microscope. If one see malaria parasites then the patient has malaria. Quick diagnosis and treatment of malaria with anti-malarial drugs prevents deaths and reduces transmission. In this work automatic detection of malaria from blood images was done and 100% accuracy and sensitivity was found.

THD Analysis of Non-Linear Loads

admin — Wed, 21 Aug 2019 11:19:04 +0000

Abstract: The power quality is deteriorating day by day due to the extensive use of power electronic based devices which have non linear relationship between voltage and current. The major domestic and industrial non-linear devices are major source of harmonics in power supply network. The harmonic is measured in various indicators but Total Harmonic Distortion (THD) is one of the popular harmonic indicator. In this paper detailed harmonic analysis is carried out in respect of THD in load current of non linear devices. The THD values of all the non-linear loads are analysed and evaluated in current spectrum with the help of Power Harmonic Analyzer.

Performance Evaluation of Cross Layer Routing Metrics in Multi-Radio Wireless Mesh Network

admin — Mon, 26 Aug 2019 11:05:22 +0000

Abstract: Wireless Mesh Networks (WMNs) have recently attained lot of popularity due to their rapid development and instant communication capability. The two factors that influence the performance of wireless routing are routing metrics and routing algorithms. Most of these metrics are designed using cross layer approach for specific type of mesh networks. Therefore there is a need for evaluating the performance of these routing metrics in infrastructure WMN. In this paper we study and evaluate the performance of three cross layer routing metrics of OLSR (optimized link state routing protocol) using NS-2. The routing metrics that we compare include Expected Transmission Count (ETX), Contention Aware Transmission Time (CATT) and Metric for Interference and Channel Switching (MIND). The results show that MIND and CATT improves the throughput and decreases the delay. However, ETX performance is poor compared to other metrics.

A Review of Locomotion Mechanism for Wireless Capsule Endoscopy

admin — Fri, 27 Sep 2019 10:07:43 +0000

Abstract: Wireless Capsule Endoscopy (WCE) is one of the most influential creations of modern science in biomedical engineering to investigate the entire Gastrointestinal (GI) tract compared to the conventional endoscopy or colonoscopy. It is a swallow-able, non-invasive, painless and patient friendly investigation process of the interior of the human body. WCE is actually a pill shaped device embedded with a camera, a coin like battery and a data transfer. But it takes a long time to travel the total GI tract. Because its locomotion depends only on the peristalsis of the intestine. In order to overcome this core drawback of current commercialized WCE products active locomotion is proposed as a series of strategies used to effectively navigate the device into different organs and conduct therapeutic functions within targeted human tissues. Reviews of several designs in this aspect of research will be discussed in this article.
