The VLSI architecture for a high-performance Low power thermometer code to digital converter using Wallace tree encoder is proposed in this research. When transforming code of thermometer type to binary type, WTE is utilised (analog to digital conversion). This is a type of flash ADC with an encoder, group of resistors and a comparator circuit, and it is a high-speed application. To obtain binary code from the comparator's output, an approximate encoder is necessary. The encoder's energy consumption is a crucial problem when constructing a low-power flash type of ADC. Wallace tree encoders decrease mistakes caused by the presence of zeroes in a succession of ones presence to a sequence of zeroes at a comparator output, but they consume excess power. A low-power WTE is constructed using a PTL full adder to overcome the issue of excessive power consumption. The proposed device uses only 616.4nW of electricity and has a 57.13-second delay. CADENCE 5.1.0 EDA is used to design the circuit and simulated using spectre virtuoso.

Schizophrenia (SCZ) is a severe mental disorder that affects behavior, speech, mood etc. of people across the world. Early detection of SCZ can play a vital role in planning the treatment for patients. Recent studies confirms that Electroencephalography (EEG) signal can be used effectively for detection of SCZ. This work attempts to propose a simple machine learning based model with improved performance for detection of SCZ. The study was conducted on 19 channel rest state EEG signal recording of total 16 subjects out of which 8 were SCZ and 8 healthy controls (HC). After acquiring the signal, preprocessing is done and signal is decomposed using Empirical Wavelet Transform (EWT) to analyze the EEG components. 3 different entropy features were calculated over the decomposed signal. The features of selected significant mode function were applied to the classifiers named as support vector machine (SVM), k-nearest neighbor (KNN), linear discriminant (LD) and neural network. Results indicates that EWT could be a useful method for analysis of EEG signal and classification problems as various classifiers namely Fine KNN, Quadratic SVM and Wide Neural Network achieved the best classification accuracy of 87.5% with 5-fold data division protocol.

Techniques approaching k-anonymity for shielding the mini data privacy over data mining. Mini gatherings and abstraction are two conventional techniques for deploying the k-anonymity method. However, the above two methodologies lead to major errors over the anonymity of combined small data gathering. To approach this problem, we propose an efficient and new anonymity method SAKA that accommodates extra semantics than abstraction and mini data gatherings that can handle combined small data combinations. SAKA is the abbreviation for Semantics Accommodated K-Anonymity technique implied for anonymization of assorted data. The concept of SAKA is to merge the mean assorted vector of arithmetic data with abstraction values of classified data as a grouping centroid. It uses its epitome of tuples along with its equivalent clusters. Here we propose efficient algorithms to anonymize assorted data. An empirical result proves that SAKA can anonymize the assorted mini data persuasively and the algorithm implemented will provide good rapport between the quality of data and effectiveness of the algorithm thus it correlates anonymization algorithms with anonymous data.

This work is dedicated to implementing a LCL filter-based grid-tied converter with a reduced sensor approach. A conventional system requires two grid-side current sensors, two capacitor-side voltage sensors, and two inverter-side current sensors. This paper has proposed a novel method that leads to a substantial reduction of the sensor. In this method, a single grid-side current sensor is required to perform the control methodology. In this technique, the grid current reference in the d-q axis is used for estimation of grid current in ß axis. As an outcome, the size, weight, cost, and complexity of the system are reduced. A comparative assessment is performed between the proposed system and the conventional system. The system offers a cost-efficient solution for grid integration. The proposed system is validated by simulation results obtained from Matlab/Simulink platform.

As the world is becoming technosavy, heading towards invention of advance electronic devices so is the safety factor of technicians becoming an important trouble of worry. The life of operators is in danger as they work on these electrical appliances. They work by changing off the circuit breakers but sometimes someone can unknowingly on the circuit breaker while they are working and this could result in massive accidents sometimes it can even result in fatal accidents. To avoid such accidents there must be system for ensuring security of technicians. Also, if sometimes the current of a particular electronic device exceeds its rated current, the device may get damaged. To resolve all these difficulties, we derived up with a solution of Circuit Breaker that is authenticated i.e., password based and a current sensor which produces an alarming sound as the current of particular device exceeds its rated value. When the Circuit Breaker is authenticated, it also has high security that no one can operate it without knowing the password.

This paper discusses about the operation of proposed flyback based reduced ripple AC-DC converter, which can be utilized for applications such as Light Emitting Diode (LED) lighting, battery charging and etc. The proposed converter is derived by connecting a boost converter across the terminal of output of the flyback converter. The discontinuous conduction mode (DCM) operation of the flyback converter helps to achieve power factor greater than the 0.985 as well as voltage step down with universal input voltage range (90V-270V). The boost converter connected parallel to the output voltage supports to eliminate the low frequency output voltage and current ripple. Hence, the capacitance required by the output filter will be reduced significantly, which leads to replacement of bulky electrolytic capacitors with film capacitors. The operation of the proposed LED driver for 62W/0.5A LED under universal input voltage range has been validated through the simulation study in PSIM software and achieved a current ripple of less than 5% with reduced capacitance.

Zero voltage switching (ZVS) in dual active bridge (DAB) converter decreases the switching losses and proves to be more efficient while the converter operates at high switching frequency. In order to extend the ZVS range for achieving lower switching losses at light loads, detection of ZVS becomes important in DABs. This paper presents a simple approach to ZVS detection technique for a single phase shift (SPS) control based DAB. The proposed technique uses the voltage information of the switching device during the start of turn-on transient for detecting the ZVS condition. The proposal makes use of the idea that the voltage across the switching device is negative at the start of turn-on transient following a ZVS state while the same is positive following a hard switching state. The detection circuit is employed using a single resistor, a single D flip-flop, single op-amp based comparator and two schottky diodes - resulting in fewer components, cost effective and simpler design. The proposed method gives an added advantage wherein a single ZVS detection circuit is sufficient for ZVS detection of one full bridge of the DAB structure. The operation of the proposed ZVS detection technique was tested in Matlab/Simulink environment for a 2 kW DAB converter. The principle operation of the developed ZVS detection circuit was also tested in hardware by using a constant voltage in the place of the switching device.

Evolution in the field of hydroelectric-power station is depends on precipitation pattern but diminish rainfall leads to shortfall of water in hydroelectric plant's reservoirs due to climate change. To get vindicated solution from this problem, normal hydroelectric plants may be re-planed by pumped storage units incorporating with wind energy. Wind energy is mostly carbon-free and can give standby mode to the hydropower station for continuous electricity-generation. The present study has been carried out in a small barrage of Tamil Nadu, India, to get economic power outage. A real-time data-based hybrid energy system is proposed in an existing barrage to get more facilities from renewable resources. So, we are expected to get economic growth over the lifetime with challenges of unpredictable inputs, seasonal variation, and fluctuating loads. Study concluded that wind energy with a pumped hydro storage system is a serviceable choice for restoring the execution of small hydroelectric barrage.

Electromagnetic vibration is a crucial aspect which may cause stability problems and disturb the stable operation of the system. DFIM variable frequency operation mainly depends upon rotor excitation through Voltage Source Converter (VSC). The converter's switching frequency is selected depending upon the magnitude of current, i.e., the thermal limit allowed. Using PWM in converter gives rise to Electromagnetic force harmonic content. when frequency and order of exciting Electromagnetic (EM) force conflicts with the natural frequency of the machine structure, a high level of vibration may result, additionally may be mechanical resonance. This paper compares stator magnetic vibration for a doubly fed induction machine with its rotor winding excited through a two-level voltage source converter at two different switching frequencies. Parameters selected for comparison are vibration acceleration and the associated defor-mation. For structural analysis, modal analysis is a prerequisite and has been performed on Doubly fed Induction Machine (DFIM) stator to calculate stator EM Vibration.
