The Voltage controlled oscillators (VCO) are the useful and important component in data communication systems and must needed in applications like a modulation, demodulation and clock generator circuits. This paper focused on design of different voltage control oscillator (VCO) topology as basic, output switching, power switching, current mirror and symmetrical load with stability of oscillation frequency...
Induction heating has become extremely popular in recent times across the globe, as most of the kitchens use induction cookers for preparing food. It has become especially popular owing to their increase in efficiency and user friendliness. Because of the advancement in technology, it is now possible to use this device in household applications. Owing to induction heating the pan is directly heated...
The diagnosis using palpation is adopted in almost all medicine systems. The pulse reading instrument helps physician in examining the palpation of the patient. However, wrist pulse reading is one of the frequently used method for disease diagnosis by Ayurvedic1 practitioner. Hence the wrist pulse reading instrument designed based on the Ayurvedic palpation method for examining Nadi2 will be of great...
Diagnosis of disease is done by physical examination of patient by physician. For internal observation physician requires help of sonography, MRI, pathological tests reports etc. In Ayurveda Nadi-Pariksha (pulse examination) is used for making the diagnosis. It uses pulse signal sensed at radial artery on wrist below the thumb for diagnosis manually. The pulse signal contains very useful information...
The objective of this paper is to develop an easy, efficient and robust algorithm for the analysis of electrocardiogram signals. The technique used in this algorithm is based on the use of Moving Average Filters and Adaptive Thresholding for QRS complex detection. Several established ECG databases published on PhysioNet with sampling frequency ranging from 128Hz–1KHz, were used for analyzing the technique...
Advanced Heavy Water Reactor (AHWR), a large nuclear reactor in which heat removal is based on natural circulation of light water in coolant channels, is described by an 80th order model for accurate representation of its core neutronics behavior. The model, besides being nonlinear, is stiff and control design and analysis studies for AHWR are accompanied by serious numerical ill-conditioning problems...
Brain tumor is a debilitating condition and is one of the leading causes of cancer -related deaths in the world today. Depending on the direction in which the tumor is spreading, the brain tumor is classified into various categories and the course of action for its treatment is chosen. This paper presents a novel approach to monitor the direction and amount of brain tumor propagation. This is achieved...
Controller design for magnetic levitation systems is considered to be difficult due to uncertainties and nonlinearities which existed in the system. The plant has inherently strong nonlinearities due to the natural properties of magnetic fields. Also the external disturbances will deteriorate the dynamic performance of the magnetic levitation system, and may give rise to system instability. These...
The paper proposes a novel, simple and faster learning approach named ‘Extreme-ANFIS’ to tune premise and consequent parameters of Takagi-Sugeno Fuzzy Inference System (TS-FIS). Further the Extreme-ANFIS is used to design inverse model of nonlinear dynamical system. In this paper, the product concentration of non-isothermal Continuous Stirred Tank Reactor (CSTR) is controlled effectively by controlling...
Cloud computing is one of the best emerging parameter in IT industry which provides on demand services. It uses Central remote server and internet for maintaining data and applications. Users can access their files and applications through internet access. As it is publically available so data security must be required. In this paper, we have analyzed different security and application aspects of...
This study paper proposes Geo-Intelligence based algorithmic development of fiber fault localization system (FFLS) for rural India. This research is to support fiber fault localization for 2, 50,000 Gram Panchayats (GP) under Govt. Of India NOFN (National Optical Fiber Network) project. In absence of basic infrastructure facilities in rural areas e.g. approaching road etc., the biggest challenge for...
The smart lighting control in the new commercial studios and smart homes not only provides the user with better control but also enhances the aesthetic value of the place. This control is achieved by profiling and controlling the lights by using user defined lighting conditions. One possible and a neat way is by using NFC Tags loaded with the user profile details and also the intensity or color details...
Image colorization is method of adding colors to a graytarget image from multichrome source image. The proposed method performs automatic colorization using LBG codebook generation algorithm with assorted similarity measures for mapping of grayimage pixels with relatively analogous multichrome image pixels. The detailed performance assessment of the different similarity measures on the quality of...
A wireless sensor network could be either homogeneous network or heterogeneous network. Depending upon the nature of application requirements a wireless sensor node could either be static or mobile one. When the nodes are static, data collection by the sink from various sources will be difficult and time consuming process. Also static deployment of sink as well as source nodes lead to energy hole...
Flight control law software have errors. Some are found during the extensive testing and certification process and others pass through causing accidents. The testing of flight control software indicates that the code and the model match. But it is very difficult to ensure if the model was correct in the first place. Model checkers like Mathworks Simulink Design Verifier check the models against formally...
The computation of Cache Related Preemption Delay (CRPD) is an important problem to assess the schedulability of a task system. In this paper, we have introduced a novel method to calculate tight bounds on the number of preemptions of every task using the concept of non-nested preemptions. We have modified existing analytical techniques to calculate CRPD using these tight bounds. An algorithm is presented...
The Universal Serial Bus (USB) Specification allows combination of different USB components into a single device. This creates a composite device and each component is recognized as an independent device. The aim of the paper is to introduce a novel concept to combine some commonly used USB classes in a single device to create a composite device that functions in multiple ways. The paper shows some...
In this paper, an online tuning of fractional order proportional integral and derivative controller is proposed. Here, the process parameters of an unknown plant is first modeled into an equivalent First Order Plus Dead Time(FOPDT) process by using online method where an ideal relay is connected in parallel to a Fractional Order Proportional Integral Derivative (FOPID) controller. The FOPID controller...
Proper validation and verification of electrical and electronics products in the design and development phase is very important. Companies manufacturing these products invest a significant amount of money and effort in verification and validation of their products before starting mass production for market, resulting in an increase of the overall development cost of these products. This paper provides...
Zinc Oxide nanoparticles' thick film sensors doped with tungsten,has been developed and its response towards alcohol has been measured. The nanoparticles were synthesised by the chemical combustion technique and characterised by XRD, FESEM and EDS. It was established that the nanoparticles exist in a hexagonal system in a primitive lattice with no other impurities. A study on the sensing performance...
