      Abstract: The Electrical Power System generally consist of the Generation, transmission and distribution and this system require an adequate protection in it layers of operation to help protect electrical loads and equipment from damaging as to ensure healthy and quality power supply in the power system. The fault associated with this substation are short circuits, overloads, phase unbalance/imbalance, poor usage of protection which in turns causes regular trips/damage on equipment at the injection substation, this fault should be taking care of with a backup protection and main protection like impedance relay and differential relay respectively. In this research work: Determination of Effective Protection on Agip 15MVA 33/11KV Injection Substation. Switch Gears has been selected as a measure to cushion regular load damages or equipment failure, which has an adverse effect to the Injection Substation. ETAP SIMULATION was used to simulate the substation/data network to check the short circuit and it response time, at different fault level on bus 1 in figure 4.2, 4.3 and 4.4. The result in 4.4 shows that at 0.025seconds there was a severe fault between line A and line B. The fault was cleared at 0.11seconds using a self-reset relay which reconnect the line upon clearing fault, also the relay coordination at time 0.03sec and current 1.5kA disconnect automatically leaving the rest of the feeder operating healthily which makes the Agip 15mva, 33/11kv injection effective. On this note it will be best fit to protect bus 1 with SF6 circuit breaker cum differential relay that will mitigate the fault from spreading to other parts of the substation equipment through the bus bar.

  • Visualizing And Forecasting Stocks Using Single Page Application

      Abstract: In the fields of finance and economics, stock price forecasting is a vital and crucial subject. The stock market is not governed by any significant rules that may be used to anticipate or estimate the price of a stock. In an effort to forecast the price in the stock market, several techniques are employed, including technical analysis, fundamental analysis, time series analysis, statistical analysis, etc. However, none of these techniques has been consistently demonstrated to be an effective prediction tool. We attempt to implement, forecast and analyze stock market prices in this paper. With breakthroughs in the fields of computer and artificial intelligence, neural networks based on machine learning techniques are becoming more effective for stock price prediction and modelling. The relationship between the selected elements and share price is formed using the dash library in Python, which can aid in anticipating accurate outcomes. Despite the fact that the stock market can never be precisely forecasted owing to its unpredictability, the purpose of this project is to use the notion of prediction and analyze data in order to forecast stocks.

  • Design of Low Noise Transimpedance Amplifier using Multiple Feedback
           filter Topology

      Authors: E. N. Ganesh
      Pages: 25 - 30
      Abstract: This study presents the highly linear and low noise transimpedance amplifier (TIA) based on CMOS inverter as an amplifier within multiple feedback (MPFB) filter topology. Absence of complex analog circuitry and compatibility with widespread digital CMOS processes highlight this TIA topology as
      the best choice in signal conditioning chains approaching analog-to-digital converters (ADCs). Special attention has been given to the TIA stability and compensation networks. Using dedicated low-dropout (LDO) regulator, the variations in TIA performance induced by supply noise have been made more robust. Transimpedance and bandwidth programmability is ensured by design of the feedback network. Nominal transimpedance and bandwidth at 65°C are 72 dBΩ and 5 MHz, respectively. Achieved third-order intermodulation distortion is –84 dBc, while input third-order intercept point is 34 dBm. This performance is comparable with state-of-the-art TIA solutions used in optical receivers and communication baseband circuits. Basic CMOS inverters were utilized as intensifiers which saves region, yet challenges soundness of the enhancer. Crossing shaft parting pay network between TIA stages is executed while transfer speed, bending level and clamor execution were kept inside wanted edges. This multiple feedback topology gives highly linear CMOS inverter that can be utilized for excellent signal conditioning circuits and applicable for high linear operations.

  • A Protective Smart Cap System for Social Distancing and Spreadable
           Diseases

      Pages: 29 - 33
      Abstract: In the current situation of COVID-19 disease; the aim should be to prevent the spread of the virus to the community. To achieve this, we must ensure that an appropriate social distance from individual to individual is maintained. To ensure that proper social distance is maintained and virus spread is reduced at the individual-to-individual community level, we have proposed the idea of a social distance warning cap. With the help of four ultrasonic sensors placed at four sides of cap we have measured distance to be maintained in 360 degrees. Additionally, a buzzer that alerts the person from a minimal distance is installed. This technique is beneficial since everyone, whether a toddler or an adult, uses caps frequently. To ensure that proper social distance is maintained and virus spread is reduced at the person to person level, we have proposed the idea of a social distance Protective Smart Cap system.

      Pages: 34 - 40
      Abstract: Dim and Fog climate weakens the scene brilliance and causes trouble in distinctive the variety and surface of the scene. A significant stage in de-hazing is the recuperation of the worldwide air-light vector. Customary techniques for the most part decipher the RGB worth of the most splendid district in cloudiness pictures as the air-light. The earlier uses the measurable perception that far off view objects become the most cloudiness, misty because of the pixel acceleration towards the higher force side. The similar assessment on an assortment of murkiness pictures shows that the proposed earlier performs better compared to existing air-light recuperation strategies and can be utilized for ensuing de-hazing applications. We eliminate the dimness in the caught picture and upgrade the picture involving contrast methods in picture handling using Dark Channel Prior (DCP) one of the image processing methods. In python calculation is executed and the calculation will be finished.1this python is also used in many applications as UAV, Machine learning, and Autonomous vehicles.

  • Energy-efficient and low-complexity linear phase filter design

    • Free pre-print version: Loading...

      Authors: Zainaba AbdulRahiman
      Pages: 41 - 53
      Abstract: Digital signal processing (DSP) systems require digital filters as a critical component. DSP is one of the technologies that will have the biggest impact on science, engineering, and technology. For many portable signal processing applications, linear phase FIR filters with high throughput, good energy economy, and low latency are extremely desirable. The trade-off between performance indicators makes it difficult to boost throughput and energy efficiency while lowering low complexity. This study of existing high-performance FIR filter designs is done in this paper. The main goal is to decrease critical path complexity, latency, and delay in order to increase throughput. Cadence is used for performance parameter observation and simulation. An adequate conclusion could be reached by contrasting conventional, linear phase techniques with filter implementations for 16 and 32 tap sizes.
