Abstract:

Internet of Things (IoT) is distinct as a paradigm wherein things armed with sensors, actuators, and embedded processors connect with everyone to help significant determinations. Secure communication in IoT is a demanding issue since IoT suffers from different vulnerabilities. Low memory capabilities, limited power supply, constrained resources are unique characteristics but at the same time these are making IoT prone to various attacks. These attacks turn into more effective when introduced with collaboratively. Various protocols and secure algorithms are developed to make the communication problem free from intruders. However, the existing protocols are not providing absolute solutions to the security issues for evergrowing IoT applications. This paper tries to figure out the performance issues by evaluating routing protocols AODV, LOADng, RPL, and CORPL under collaborative attacks.

Abstract:

Reactive Powder Concrete is a budding composite material which has created a platform for the industry to optimize materials for economic profit and building structures that are strong and durable in nature . In early 1990’s , Bouygues’ lab in France introduced RPC to the world . RPC represents a new class of ultra high performance concrete with compressive strengths in range of 180MPa . RPC does not include any coarse aggregates and but has steel fibersto enhance the strength.RPC includes Portland cement, silica fume, fine sand, Superplasticizer, water and steel fibers. In this study, RPC is developed using metakaolin as replacement for cement to achieve target compressive strength more than 120MPa.

Abstract:

The marketing is a process of exchanging products with suitable information. The information about the exchangeable products carried through advertising and this information passes to the potential customers. In the competitive world, effective advertising is important to capture and retain the consumers. Grabbing the attention of existing or potential customers is essential, to positively influence the sales. After all, attention is the first principle of the AIDA theory in advertising. The theory calls for advertisements to catch the attention of the audience, create interest in the offerings, generate desire for the product / service and trigger action for buying the products. Advertising is a means of communicating information of comparing and selecting the available products to the consumers. It stimulates the availability of goods and services is higher, Stabilization in price of products which leads to upsurge in the production system and generates employment.

Abstract:

Fundamental analysis is a method of analyzing the financial data (fundamental data) for determining the stock value of a company which it considers variables such as company’s earnings, dividends, and sales. Fundamental analysis does not look at the behavior variables and does not considering the overall state of the market. Exclusively fundamental analysis focuses on the business companies for determining whether the stock should be bought or sold. In Indian stock market as well economy the position banking industry is very strong. The objective of the study is to analyze the profitability position of the public and private sector banks in India. The data collected from the financial statements of both public sector(State Bank of India-SBI, Bank of Baroda-BOB, Punjab National Bank-PNB) and private sector banks (Hosing Development Finance Corporation-HDFC & Industrial Credit Investment Corporation of India-ICICI) from the period of 2014-2015 to 2018-2019. This analysis helps to the shareholders for taking decision making statements in terms of profitability. The variables used in this study are Operating Profit Margin (OPM), Net Profit Margin (NPM),Return on Capital Employed(ROCE), Earnings per Share (EPS) and Price/Earnings (P/E) ratio

Abstract:

Better torque control can be obtained by the use of Direct torque control (DTC) instead of Field oriented control (FOC) in steady state and transient state operating conditions because of its simple control structure. Robustness and fast torque response are the advantages of Direct torque control (DTC). Stator flux estimation is difficulty under low speed operation due to existence of open loop integrator and improper working of an open loop voltage model, hence an adaptive fuzzy system is adopted which improves the machine performance by eliminating open loop integration, minimizing stator current distortions, constant switching frequency, fast response of rotor speed and stator flux electro-magnetic torque without ripples. In this paper an adaptive fuzzy controller is adapted which improves system performance and subdues high torque ripples. For the proposed system simulation results are carried out.

Abstract:

This paper proposes Modular Multilevel Converter (MMC) for an application of shunt active power filter to harmonic reduction and Reactive Power Compensation (RPC). High frequency switching control techniques of level shifted carriers to control Insulated Gate Bipolar Transistor (IGBT) switches of three-phase Modular Multilevel Converter (MMC) is proposed. Half Bridge Sub Modules (HBSM) is proposed due to low conduction losses for testing the performance of MMC using proposed control techniques. An instantaneous real and reactive power (PQ) method is used to extract harmonic current. The Proportional Integral controller (PI) is implemented to control the capacitor voltage. The Carrier Based Phase Disposition Pulse Width Modulation (CBPDPWM) scheme is employed to control the switches in systematic manner. The triangular wave in different configuration is used as a carrier signal to generate the gate pulses for IGBT switches. The performance of parameters includes reactive power compensation and Total Harmonic Distortion (THD) is discussed and presented for different types of high frequency switching techniques under nonlinear loads. The proposed work is simulated in the environment of Matlab/Simulink.

Abstract:

The integration of photovoltaic systems (PV) into the grid has raised concerns for distribution power generation systems (DPGS), including islanding fault detection. Inverter based PV system require an effective anti-islanding method. A new anti-islanding method presents for the DPGS. This method is based on introducing the harmonic component at the inverter side and phase-locked loop (PLL) based synchronization. The output reference current is modifying by each cycle by an injected signal. The disturbance caused by injected signal is small compared to other anti-islanding methods. This proposed method does not affect the zero crossing of the injected signal. The performance of the proposed method has been studied using MATLAB/Simulink.

Abstract:

This paper presents constant sampled random PWM techniques with low computational burden for vector controlled induction motor drives. The classical space vector PWM (SVPWM) method involved with more computational burden due to more calculations. Also, it generates high amplitude harmonics nearer to the multiples of switching frequency of the inverter. Hence, the proposed approach generated the modulating signals of SVPWM method by using a simple scalar technique. Further, to mitigate the harmonic amplitudes, three types of random PWM (RPWM) methods with fixed sampling frequency are proposed for vector controlled induction motor drive. The effectiveness of the proposed PWM methods is confirmed with simulation and experiments on induction motor drive.
