Pages: 189-193

Abstract: Covid19 is a newly discovered corona virus that has been officially announced as a pandemic by the World Health Organization in March 2020. It is a new virus in the medical field that has no specific treatment and no vaccines until this moment. Covid19 is spreading very fast as the medical systems over the world are not able to hospitalize all the patients which lead into a significant increase in the number of the virus death. This work uses machine learning models to predict which patient has a higher probability of death. Three different algorithms such as multilayer perceptron, support vector machine and K nearest neighbor were used in this work. The accuracies achieved were between 92% to 100% with MLP, SVM and KNN. SVM achieved the highest accuracy. The models were evaluated through precision, accuracy, recall and F measure.

Title of the Paper: Comparative Study On Cloud Computing Simulation Platforms


Authors: Samah Alshathri

Pages: 172-177

Abstract: Experimentation in a real environment is quite problem due to the high financial cost and the time required to accomplish it. Above all that, the tests are not repeatable, because many variables cannot be controlled with in the test, which may affect the results. Therefore, using simulation frameworks to evaluate cloud applications is preferred. It is extremely difficult to use real infrastructures for benchmarking the application performance (throughput, cost benefits) under inconstant conditions. Therefore, we cannot execute benchmarking experiments using real-world Cloud environments. To overcome this challenge, the use of simulation tool is the best applicable choice to the developers with substantial resources and parallelized execution. These simulation tools offer the researchers the chance to evaluate the hypothesis in a measured environment and simply emulate the output results. This paper have reviewed and classified the most updates and extends simulation platforms in cloud computing and gave examples on each.

Abstract: Nowadays, the real-time speaker recognition system is very popular due to its cost-effective nature. However, it is a very challenging one to produce a more efficient speaker identification system. In our work, we work on a multi-lingual real-time speaker identification system. We work in a novel way to enhance the efficiency of the said system. We take some real speech signals and use different speech enhancement methods and our proposed voice activity method (VAD) to enhance the efficiency of said system. By doing so, we increase the accuracy of the said system relatively by 2% as compared to existing methods.

Title of the Paper: Analysis of a Regulated Cascode Cross Couple Power Amplifier


Authors: Kittipong Tripetch

Pages: 153-158

Abstract: The input impedance of a regulated cascode cross couple amplifier is derived. The frequency response of the input impedance polynomial form can be plotted with MATLAB. From the polynomial form of the input impedance of the proposed circuit, it can be transformed by substitute complex frequency s with jω into the polynomial form equation. After that, this function can be grouped into a symbolic real and a symbolic imaginary form. The next step in derivation is to multiply this function with a complex conjugate function of the symbolic complex form of the input impedance. The last step is to plot a real and an imaginary part as a function of the input frequency so that the power amplifier can be matching with the various matching circuit according to the condition of the maximum power transfer.

Title of the Paper: Low power CMOS based Self Controlled Precharge Free Content Addressable Memory with Minimum area for Image Processing Devices


Authors: S. Arulpriya, P. Kumar

Pages: 144-152

Abstract: Image processing devices plays a vital role in several applications like medical, security, biometric etc. The devices ranges from portable size to larger machines with and without Human Computer Interface possibilities. As the image processing and human computer interface system application requires higher memory requirements, the power and area should be small. Searching of data is a high priority work in image classification. To perform high speed search through hardware Content Addressable Memory is used. But the circuit suffers from higher power consumption, precharging issues and low performance. For longer word length the elimination of precharge is needed. So for high speed applications self-controlled precharge-free CAM (SCPF-CAM) is suitable. A 4T hybrid self controlled pre charge free Content Addressable Memory is proposed in this paper using CMOS 32nm technology. The observation shows that the circuit works at high speed, minimizes the search time and has high performance operation. When compared to the conventional SCPF-CAM, 8T CAM the proposed design reduces the number of transistors. The reduction in area is about approximately 20% and can be used in low power and low energy applications. In Synopsis HSPICE Predictive technology models were used for the implementation in 32nm CMOS technology. The work will be extended in future using FinFET technology where the leakage current can be minimized.

Title of the Paper: Development of a Single Screw Extruder For The Production of Wood-Plastic Composite


Authors: Omoniyi T.E, Adesanya D.E

Pages: 133-143

Abstract: A wood-plastic composite extruder (single screw extruder) was designed, fabricated and evaluated to recycle and produce a product for non-structural purposes. The extruder is separated into four units: The feeding, conveying, heating and forming unit. The material is fed by gravity into a hopper and conveyed by a screw conveyor at a predetermined speed through a heated barrel and the extrudate is metered through the breaker plate and the die. The output rate is directly related to the screw speed. Test samples were produced with the machine and experimental tests were conducted to determine its suitability for non-structural purposes and applications. The performance evaluation test on the machine shows that at speeds of 4rpm and 50.25rpm, the machine performs at 87% and 82% efficiency respectively which makes it effective for production. The machine takes a maximum of 5mins to recycle a batch with an average capacity of 14.04kg/hr at 4rpm and 17.55kg/hr at 50.25rpm. The machine conserves cost and energy due to low specific mechanical energy consumption of 191.21kJ/kg

Title of the Paper: Five-level Direct Torque Control with Balancing Strategy of Double Star Induction Machine


Authors: Elakhdar Benyoussef, Said Barkat

Pages: 116-123

Abstract: This work relates to the study of direct torque control of the double star induction machine drive fed by two five-level diode-clamped inverters. The analysis of the three-phase direct torque control shows that this concept can be extended easily to double star induction machine even when it is fed by a multilevel inverter. Diode-clamped inverter, as one of the prominent multilevel inverters, has several advantages like high voltage and low current waveform distortion. However, it suffers from the problem of neutral point potential variation. The variation causes an unbalance in the DC-link voltage levels and increases consequently the current waveform distortion. This problem can be solved in satisfactory way by using multilevel direct torque control equipped by a balancing strategy. The simulation results, illustrating the steady state and dynamic performances, prove the effectiveness of the proposed control approach.

Title of the Paper: High CMRR Voltage Mode Instrumentation Amplifier Using a New CMOS Differential Difference Current Conveyor Realization


Authors: T. Ettaghzouti, N. Hassen

Pages: 87-96

Abstract: This paper describes a new CMOS realization of differential difference current conveyor circuit. The proposed design offers enhanced characteristics compared to DDCC circuits previously exhibited in the literature. It is characterized by a wide dynamic range with good accuracy thanks to use of adaptive biasing circuit instead of a constant bias current source as well as a wide bandwidth (560 MHz) and a low parasitic resistance at terminal X about 6.86 Ω. A voltage mode instrumentation amplifier circuit (VMIA) composed of a DDCC circuit and two active grounded resistances is shown as application. The proposed VMIA circuit is intended for high frequency applications. This configuration offers significant improvement in accuracy as compared to the state of the art. It is characterized by a controllable gain, a large dynamic range with THD less than 0.27 %, a low noise density (22 nV/Hz1/2) with a power consumption about 0.492 mW and a wide bandwidth nearly 83 MHz. All proposed circuits are simulated by TSPICE using CMOS 0.18 μm TSMC technology with ± 0.8 V supply voltage to verify the theoretical results.

Authors: Hamed Bagheri, Mahdi Sajjadi, Ramin Chimeraad

Pages: 81-86

Abstract: A turbine spirometer with an IR rotary encoder is designed and fabricated for performing Respiratory Function Tests (RFT). The system includes a hardware for gathering breath inspiratory flow rate and a user software which represents analyzed data of patients' breath flow and volume parameters in real-time. A major challenge in design of flow-based spirometers is the accuracy of device in measuring volume parameters of RFTs which is due to large effects of sensing data error and noise. The purpose of the paper is evaluating the efficiency of three different types of digital noise reduction filters in term of improving the accuracy of system in calculation of air volume passing through the spirometer turbine by use of data obtained by the innovative flow sensor. Three distinct kinds of flow waves are experimented and the most sufficient filter for corresponding respiratory function tests are reported.

Title of the Paper: Hybrid Between Ontology and Quantum Particle Swarm Optimization for Segmenting Noisy Plant Disease Image


Authors: Eman K. Elsayed, Mohammed Aly

Pages: 71-80

Abstract: One of the main risks to food security is plant diseases, but because of the absence of needed infrastructure and actual noise, scientists are faced with a difficult issue. Semantic segmentation of images divides images into non-overlapped regions, with specified semantic labels allocated. In this paper, The QPSO (quantum particle swarm optimization) algorithm has been used in segmentation of an original noisy image and Ontology has been used in classification the segmented image. Input noisy image segmentation is limited to a classification phase in which the object is transferred to Ontology. With 49,563 images from healthy and diseased plant leaves, 12 plant species were identified and 22 diseases, the proposed method is evaluated. The method proposed produces an accuracy of 86.22 percent for a stopped test set, showing that the strategy is appropriate. EPDO (Enhance Plant Disease Ontology) is built with the web ontology language (OWL). The segmented noisy image elements are paired with EPDO with derived features that come from QPSO. Our results show that a classification based on the suggested method is better than the state-of-the-art algorithms. The proposed method also saves time and effort for removing the noise at noise level from the input image σ=70

Pages: 62-70

Abstract: Since last few years, the tiny size of MOSFET, that is less than tens of nanometers, created some operational problems such as increased gate-oxide leakage, amplified junction leakage, high sub-threshold conduction, and reduced output resistance. To overcome the above challenges, FinFET has the advantages of an increase in the operating speed, reduced power consumption, decreased static leakage current is used to realize the majority of the applications by replacing MOSFET. By considering the attractive features of the FinFET, an ALU is designed as an application. In the digital processor, the arithmetic and logical operations are executed using the Arithmetic logic unit (ALU). In this paper, power efficient 8-bit ALU is designed with Full adder (FA) and multiplexers composed of Gate diffusion input (GDI) which gained designer's choice for digital combinational circuit realization at minimum power consumption. The design is simulated using Cadence virtuoso with 20nm technology. Comparative performance analysis is carried out in contrast to the other standard circuits by taking the critical performance metrics such as delay, power, and power delay product (PDP), energy-delay product (EDP) metrics into consideration.

Title of the Paper: A Robust and Efficient Fault-Resilient RadHard ADPLL


Authors: Varsha Prasad, Sandya Prasad

Pages: 49-61

Abstract: The high pace emergence in semiconductor technologies and associated application demands have revitalized industries to explore power efficient, stable and fault tolerant digital communication solutions, particularly for time critical applications operating at higher frequency ranges. Thus strengthening low cost CMOS digital design with Radiation Hardened by Design (RHBD) approach can be of paramount significance compared against the high cost Radiation Hard by Process (RHBP) approach. With this motivation, in this paper a novel and robust All-Digital-Phase Locked Loop (ADPLL) design has been developed for frequency synthesis. Our ADPLL design model encompasses multiple novelties and contributions including Feedback-Divider-Less-Counter (FDLC) based ADPLL, predictive phase-frequency detection (PFD), enhanced Time to Digital Converter (TDC) to detect next-edge occurrence of the reference clock that reduces locking period and complexity. The predictive PFD applies a phase-prediction scheme that delays the clock-edges of the reference frequency with a calibrated amount that it always aligned towards the expected frequency clock edge. It makes TDC to be narrow enough to cover the reference and oscillator jitter. Our proposed ADPLL design applied a narrow range converter (TDC) that assist phase-error prediction, correction and phase detection. The reference clock delay facilitates accurate timing relationship estimation with the variable frequency and hence performs retuning of the variable clock to reduce locking period and reduce noise. The ADPLL design has exhibited satisfactory performance for the frequency synthesis with reference frequency of 20MHz and the synthesis frequency of 2.4 GHz meeting radiation hardened features. The simulation results has revealed that the proposed Rad Hard ADPLL design can be a potential solution for space communication systems by maintaining low jitter of 340ps and power consumption of 371.7mW, as the narrow range TDC designed can detect sample radiation induced impulse noise of 20ns, 1mV and correct it.

Pages: 31-39

Abstract: The earthing analysis is proposed in this paper. The effects of 3-D electromagnetic field and the influences of stray currentare considered in the text simultaneously. The activity in the high-voltage environment is risky of being injured by electricshock. The safety of personnel in and around electric power the installations has been a prime concern. Specially, the safety isgenerally in terms of the allowable touch and step voltages. These voltages are related to the earthing resistance of human foot.I ofn order to increase the safety of personnel, a high resistivity surface layer of gravel is normally existed in the substationswitchyards or other high voltage areas. The thickness of this layer will affect the calculation of the earthing resistance ofhuman foot. Thus, the effect of soil resistivity will be considered in this paper. Among them, the electromagnetic field andhumidity factors are also considered in this paper. As a result, the surface layer of gravel can be used to reduce the earthingresistance of human foot. The equivalent model of human foot was modeled by the circular plate conductor in the past. Whichconsider the beauty of the environment, most of the transmission lines are in the surface, so the transmission line generated bythe discrete current will affect the earthing resistance estimation, thus the proposed paper will consider the composition of thespecial function which is the mathematical calculus popularized by the basic theorem of calculus. On the other hand, the dampingredients, temperatures, and soil resistivity on the surface will also be considered in this paper. This paper research into theproposed method for estimating the earthing resistance of human foot and proposes an equivalent model for calculating thegrounding resistance of human foot. The comparisons of the method are also shown in this paper.
