Password plays vital role in the authentication process by providing information and computer security. We use common authentication method such as Personal Identification Number(PIN) in various devices ATM’s, mobile devices and electronic door locks. This PIN entry method is not safe. When user enters their PIN in popular place, attacker observes the PIN over their shoulder. This is called shoulder surfing attack (SSA).In this project we will propose a method to prevent this SSA attack. Whenever we need to enter PIN code, we will be using our mobile phone to type that pin code.

SHUFFLING KEYPAD FOR SMART PAYMENT TRANSFER

A Genset (or a power generator set) is a machineused to produce electrical energy from fuel. Depending uponthe type of application, the electrical energy produced by thegenset may be used as prime power (absence of utility) or backup power (utility is prime power). This application guide forthe relay protection of synchronous generators presents areview of the generally accepted forms of protection for thegenerator and its excitation system. It summarizes the use ofrelays and devices and serves as a guide for the selection ofequipment to obtain adequate protection. The guide isprimarily concerned with protection against faults andabnormal operating conditions for large hydraulic, steam, andcombustion-turbine generators. This guide is not a standardand does not purport to detail the protective requirements ofall generators in every situation. Standby and emergency usegenerators are specifically excluded. However, sufficientbackground information relating to protection requirements,applications, and setting philosophy is given to enable the userto evaluate the need, to select, and to apply suitable protectionfor most situations.

SURVEY ON GENSETS & GUIDE FOR GENSET PROTECTION

Accidents due to the hazy vision in adverse atmospheric conditions is not an issue limited to a region.It is observed worldwide that even after developing the road safety knowledge the accidents in hazy atmosphereare not reduced. These are due to some constraints like blurred vision in hazy conditions in which human eyescannot detect vehicles or other objects coming in front of vehicle. To overcome this issue there should be someinterface between the driver and the objects coming in front of vehicle. The issue occurs while driving in hazyenvironment and can be avoided by providing an interface which will store the video in form of frames at aspeed specified by the camera module used on the front panel of the vehicle. The video stored in format offrames will be processed through the Raspberry Pi which is a series of small single board computer. There willbe a provision for the driver to turn on the system whenever it is necessary by pressing a button and then therewill be a TFT display provided inside the vehicle to visualize the objects coming in front of the vehicle inadvance to the driver

Image Processing for Hazy Weather Conditions

In this paper we propose a dual polarised pentagonal microstrip antenna for massive MIMO-base station to operate at 2.4 GHz WLAN band (IEEE 802.11 b/g/n/ax). The various researchers have used antenna array with different feeds for the massive MIMO BS to obtain the desired gain with required impedance bandwidth. However, this proposed work contradicts with existing method by using a single novel radiating element with suspended substrate to achieve the desired gain and required impedance bandwidth. The circular polarisation is achieved by using two coaxial-probe feeds. The main focus of research is on the selection of proper shape of the radiating element for Massive MIMO BS. The proposed antenna is successfully simulated using HFSS 13.0, fabricated on a FR-4 substrate and measured. The proposed antenna exhibits a much higher gain of 6.17 dB, improved impedance bandwidth of 171.9 MHz (return loss, S11=−10 dB), the axial ratio (AR) is 1.78 dB (< 3 dB), the patch area of 1,775 mm2, and also yields return loss better than −15 dB around the centre frequency of 2.45 GHz. The measured characteristics of the antenna are in good agreement with the simulated results.

High Gain Dual-Polarized Pentagonal Microstrip Antenna for Wireless Communications

For safe navigation of visually impaired, an assistive system that can estimate the distance betweenvisually impaired and obstacle and can intimate the user is needed. Estimation of the distance betweenan obstacle and visually impaired (user) is challenging due to artifacts in the real environment such asvariation in speed of obstacle and non-uniform illumination conditions. This paper presents a novelalgorithm to estimate the distance of an obstacle from the user using Speeded Up Robust Features(SURF). Instead of traditional distance measurement sensors, SURF features are used for distancemeasurement of an obstacle from visually impaired. The input video frames are preprocessed, andcorrection for non-uniform illumination is applied. The dominant points in each input video frame arelocated. The correspondence between the dominant points in successive frames is derived. For a typicalcamera, the average magnitude of SURF features is a linear function of a distance between the user andthe obstacle. This function is used to estimate the distance between obstacle and user. The proposedalgorithm is tested on videos recorded in a dynamic environment. For videos captured with Microsoftwebcam, an average % error for distance estimation is 1.31%, and for speed, estimation is 4.18%. Forvideos captured with an Iball camera, the average % error for distance estimation is 2.134%, and forspeed, estimation is 0.399%. The performance of the proposed algorithm is compared with existingtechniques on the basis of an error in distance estimation, standard deviation, space complexity, andtime complexity.

An Algorithm to Estimate Obstacle Distance for Assistive System of Visually Impaired

A dual polarized (DP) 2 × 2 MIMO antenna with high gain and isolation is proposed for WLAN band (IEEE 802.11a/b/g/n) and C-band (spectrum sharing) applications. The proposed MIMO antenna design consists of two DP pentagonal microstrip elements. A slot on a ground is introduced to escalation the isolation among two antennas. The measured frequency bands extend from 2.43 to 2.54 GHz, 4.05 to 4.13 GHz and 5.22 to 5.37 GHz with VSWR &amp;lt;2. The achieved isolation between two ports is more than 30 dB. The measured peak gains at 2.45 GHz, 4.09 GHz and 5.29 GHz resonant frequencies are 7.95 dBd, 3.39 dBd and 4.18 dBd, respectively. The RT druid 5880 substrate is used for fabricating the MIMO antenna. Measured results agree with the simulation ones. The diversity performances in terms of diversity gain (DG), efficiency, and envelope correlation coefficient (ECC) have also been reported. The proposed MIMO antenna is tested using Wi-Fi router. © 2019, Springer Nature Switzerland AG.

3D Printing is a technology which is based on additive manufacturing. This technology has a potential to change the manufacturing industry by manufacturing product in the shortest time period where at first the same product required days, months or years. The study on these printers and their software is to reduce the cost of printers as compared to one already present in the market. This paper is based on the types of 3D printing methods used from the early 1980s till today and their hardware and software used. © 2018 IEEE.

In orthogonal frequency division multiplexing (OFDM) systems, the least square (LS) in addition to the technique of linear minimum mean square error (LMMSE) channel estimation are compared using frequency as well as time domain in this paper. A constant LMMSE channel estimation has been proposed in time domain where the channel is not intimated before. It is presented by the Simulation outcomes that the channel estimation execution can be improved by the techniques of time domain but not using the techniques of frequency domain. Additionally, using the technique of LMMSE, higher accuracy is achieved by the proposed method which is presented in the outputs of the simulation. © 2019 IEEE.

Synchronization and Channel Estimation in OFDM using Modified Linear Minimum Mean Square Error

MR Images contain a significant amount of noise which is complex in nature and is inconsistent throughout the image. Hence it becomes important to study a detailed relation between different statistical parameters of the image. In this paper, a ratio of the mean of the corrupted pixel intensities and the brightest pixel is found to be constant for a wide range of input noise. Using this finding, a simple equation for SNR is derived and is compared with the standard formula of SNR calculation. The absolute difference was studied and observations are drawn. The proposed algorithm was implemented on synthetic images from BrainWeb data base using MATLAB 2015a. © 2019 IEEE.
