Abstract— A scientific investigation is created to examine the nonlinear unfaltering blended convection limit
layer stream and warmth exchange of an incompressible digression hyperbolicnon-Newtonian liquid from a
non-isothermal wedge in the nearness of attractive field. The changed preservation conditions are understood
numerically subject to physically fitting limit conditions utilizing a second-arrange precise verifiable limited
distinction Keller Box method. The numerical code is accepted with past studies. The impact of various rising
non-dimensional parameters, to be specific Weissenberg number (We), power law record (n), blended

(M)and dimensionless extraneous direction on speed and temperature development in the limit layer
administration are inspected in subtle element. Moreover, the impacts of these parameters on surface warmth
exchange rate and nearby skin erosion are additionally examined. Approval with prior Newtonian studies is
introduced and amazing relationship accomplished. It is found that speed is lessened with expanding We,
while, temperature is increased. Expanding n improves speed yet diminishes temperature, a comparable
pattern was seen. An expanding M is found to decline speed however temperature increments.

Voltage Flicker Analysis and its Mitigation by STATCOM for Power Quality Impr...IJMTST Journal
Voltage flicker is considered as one of the most severe power quality problems (especially in loads like electrical arc furnaces) and much attention has been paid to it lately. The reason for this disturbance is mainly due to the large nonlinear loads such as electric arc furnaces. Due to the latest achievements in the semiconductors industry and consequently the emergence of the compensators based on voltage source converters, FACTS devices have been gradually noticed to be used for voltage flicker compensation. This paper covers the contrasting approaches; dealing with the voltage flicker mitigation in three stages and assessing the related results in details. Initially, the voltage flicker mitigation, using FCTCR (Fixed Capacitor Thyristor Controlled Reactor), was simulated. Secondly, the compensation for the Static Synchronous Compensator (STATCOM) has been performed. The voltage flicker compensation by 8– pulse as well as 12 – pulse static synchronous compensator (STATCOM) has been performed. This paper deals with the voltage flicker mitigation and reduction in total harmonic distortion (THD) and compared the results in detail. The obtained results show that STATCOM is very efficient and effective for the compensation and mitigation of voltage flicker and harmonics all the simulation results have been performed on the MATLAB Software.
Improved Power Quality by using STATCOM Under Various Loading ConditionsIJMTST Journal
A Power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency that
results in a failure or a mis-operation of end user equipment’s. Utility distribution networks, sensitive
industrial loads and critical commercial operations suffer from various types of outages and service
interruptions which can cost significant financial losses. With the restructuring of power systems and with
shifting trend towards distributed and dispersed generation, the issue of power quality is going to take
newer dimensions. Injection of the wind power into an electric grid affects the power quality. The
performance of the wind turbine and thereby power quality are determined on the basis of measurements
and the norms followed according to the guideline specified in International Electro-technical Commission
standard, IEC-61400. The influence of the wind turbine in the grid system concerning the power quality
measurements are-the active power, reactive power, variation of voltage, flicker, harmonics, and electrical
behavior of switching operation and these are measured according to national/international guidelines.
Static Compensator (STATCOM) is connected at a point of common coupling with a battery energy storage
system (BESS) to mitigate the power quality issues. The battery energy storage is integrated to sustain the
real power source under fluctuating wind power. Here two control schemes for STATCOM are Fuzzy logic
controller and hybrid Fuzzy logic controller. We can better response for hybrid fuzzy compare to fuzzy logic
controller. The STATCOM control scheme for the grid connected wind energy generation system for power
quality improvement is simulated using MATLAB/SIMULINK in power system block set. Finally the proposed
scheme is applied for both balanced and unbalanced linear nonlinear loads.
Experimental Investigation of High – Strength Characteristics of Self Curing ...IJMTST Journal
In concrete structures exposed to the ambient air at early ages, the moisture content in concrete
decreases due to moisture diffusion. In addition, self-desiccation due to hydration of cement causes an
additional decrease of moisture content in concrete at early ages, especially for high-strength concrete. In this
study, the internal relative humidity in drying concrete specimens was measured at early ages. Furthermore,
the variation of relative humidity due to self-desiccation in sealed specimen was measured. The moisture
distribution in low-strength concrete with high water/cement ratio was mostly influenced by moisture
diffusion due to drying rather than self-desiccation. In high-strength concrete with low water/cement ratio,
however, self-desiccation had a considerable influence on moisture distribution. The results obtained from
the moisture diffusion theory were in good agreement with experimental results.

(SIFT) methods for extraction. SIFT method is used to detect the images with larger corners and extract them.
SURF, the name itself represents a speed method to extract the features when compared to SIFT. KNN
classifier is used to classify the images based on the features extracted from both techniques. So these
combined processes are applied to classify tumour and non-tumour images more accurately.
Comparison of Buck-Boost and Cuk Converters for BLDC Drive Applications with PFCIJMTST Journal
The devices generally used in industrial, commercial and residential applications need to undergo rectification for their proper functioning and operation. Hence there is a need to reduce the line current harmonics so as to improve the power factor of the system. This has led to designing of Power Factor Correction circuits. This project presents a power factor corrected (PFC) bridgeless (BL) buck–boost converter-fed brushless direct current (BLDC) motor drive as a cost-effective solution for low-power applications. The conventional PFC scheme of the BLDC motor drive utilizes a pulse width-modulated voltage source inverter (PWM-VSI) for speed control with a constant dc link voltage. This offers higher switching losses in VSI as the switching losses increase as a square function of switching frequency. A BL configuration of the buck–boost converter is proposed which offers the elimination of the diode bridge rectifier, thus reducing the conduction losses associated with it. A PFC BL buck–boost converter is designed to operate in discontinuous inductor current mode (DICM) to provide an inherent PFC at ac mains. The simulation results are presented by using Matlab/Simulink software. The proposed concept can be extended with cuk converter for BLDC drive applications using Matlab/Simulink software
Reactive Power Sharing Droop Control Strategy for DG Units in an Islanded Mic...IJMTST Journal
The proposed method mainly includes two important operations: error reduction operation and voltage
recovery operation. The sharing accuracy is improved by the sharing error reduction operation, which is
activated by the low-bandwidth synchronization signals. However, the error reduction operation will result in
a decrease in output voltage amplitude. Therefore, the voltage recovery operation is proposed to compensate
the decrease., due to increasing the demand of electricity as well as rapid depletion of fossil fuels, and the
government policies on reduction of greenhouse gas emissions , renewable energy technologies are more
attractive and various types of distributed generation sources, such as wind turbine generators and solar
photo voltaic panels are being connected to low-voltage distribution networks. Micro grid is an integrated
system that contain in s distributed generation sources, control systems, load management, energy storage
and communication infrastructure capability to work in both grid connected and island mode to optimize
energy usage. The paper presents a advanced control technique for a micro grid system which works
efficiently under a decentralized control system.
Reparation of Inductive Power in Power System by the use of FACTS devicesIJMTST Journal
This paper presents a shunt type FACTS device connected across the load to improve the power flow and
to maintain the reactive power in real data transmission line power system using MiPower software. The
main objective of this work is to maintain the voltage stability of steady-state bus voltages and reactive
power flows in transmission system with and without FACTS controller. FACTS devices are capable of
controlling the active and reactive power flows in a transmission line by controlling its series and shunt
parameters. This paper presents a steady state model of Static VAR Compensator (SVC) controller in the
power system for stability enhancement. Benefits of FACTS controllers to power system are also discussed.
In this work real data system has been considered for load flow analysis and also to incorporate the SVC
controller in the system
Hybrid Micro Grid Architectures and ChallengesIJMTST Journal
The distribution system is part of the electric power system that links the bulk transmission system and the
individual customers. Increasing environmental concerns, consumer expectations in terms of reliability &
better quality of power supply and improving economics of distributed energy resources (DER) based on
renewable, is making Micro Grid a viable proposition. Present electrical distribution system offers many
technical & operational glitches for successful integration of Micro Grid Technologies. Modern Power systems
are smart, interconnected, interdependent, load sharing and phased mission systems. Micro grids are
composed by distributed generators, energy storage devices, intelligent circuit breakers and local loads. In
this paper, a review of the main micro grid architectures proposed in the literature has been carried out. The
micro grid architectures are first classified regarding their AC or DC distribution buses. Besides, more
complex micro grid architectures will be discussed. Both advantages and disadvantages of each one of the
micro grid families will be discussed.
An IOT Project Integrated with RFID and GPRSIJMTST Journal
In current scenario there is no security for the students and parents find difficulty to monitor the safety of the children when they move to school. Children may hold wrong bus or they may get down at wrong stop they may left behind the school or in the bus or they might simply skip the classes. In schools attendance were taken manually that kills the time for the teacher to call each student name and mark the attendance This project is very useful for the schools administrator to keep track of each and every student and look after their security. The main purpose of this project is to give the security for the students and to give the information for their parents to reduce their work and to reduce the burden involved in day-to-day activity of the teacher by taking the attendance. This software helps in reduce the hacking of the password and it is stored in the encrypted form. This development provides user friendliness. The main benefit of this project is for the administrator and also for the parents to reduce their burden. The project can be accessed by the authenticated users only and its dashboard helps the administrator to know about the student who is present for the class. It will notify the date and time of the student got into the bus so that it will helps the parents to know about the student information. Each module is made up of several supportive models performing various operations.
Design & Simulation of 3-Phase, 27-Level Inverter with Reverse Voltage TopologyIJMTST Journal
Multilevel inverters have been widely accepted for high-power high-voltage applications. Their performance
is highly superior to that of conventional Seven-level inverters due to reduced harmonic distortion, lower
electromagnetic interference, and higher dc link voltages. In this paper, a new topology with a
reversing-voltage component is proposed to improve the multilevel performance. This topology requires fewer
components compared to existing inverters (particularly in higher levels) and requires fewer carrier signals
and gate drives. Therefore, the complexity is greatly reduced particularly for higher output voltage levels. The
Proposed 27-level inverter is modeled and simulated in Matlab 2012b using Simulink and Sim Power

With the progress of VLSI technology, the number of cores on a chip keeps increasing, Now a days we are
increasing the processing level of the chip, NOC is a best method to interconnect the core with each other core
on the chip, it reducing the overall chip power and Traffic level by sharing the work load with other cores on
the chip. And Dynamic Voltage Frequency Scaling (DVFS) is the technique for monitoring the
Frequency/Voltage level of each core of the chip and providing sufficient power to the cores, ATPT is a Table
that having (low and high) Frequency level table of the Each core. ATPT has very high prediction accuracy
system. Depends upon the data speed of the core the voltage/frequency will be given by DVFS. If the core is
in ideal state for a while, that core is moved to low power mode. So the power of the each core will be reduced.
Navigation of Mobile Inverted Pendulum via Wireless control using LQR TechniqueIJMTST Journal
Mobile Inverted Pendulum (MIP) is a non-linear robotic system. Basically it is a Self-balancing robot
working on the principle of Inverted pendulum, which is a two wheel vehicle, balances itself up in the vertical
position with reference to the ground. It has four configuration variables (Cart position, Cart Velocity,
Pendulum angle, Pendulum angular velocity) to be controlled using only two control inputs. Hence it is an
Under-actuated system. This paper focuses on control of translational acceleration and deceleration of the
MIP in a dynamically reasonable manner using LQR technique. The body angle and MIP displacement are
controlled to maintain reference states where the MIP is statically unstable but dynamically stable which
leads to a constant translational acceleration due to instability of the vehicle. In this proposal, the
implementation of self balancing robot with LQR control strategy and the implementation of navigation
control of the bot using a wireless module is done. The simulation results were compared between PID control
and LQR control strategies.
We have calculated the minimum chip area overhead and hence the bit density reduction. In this approach,
the number of faults in each line of a memory block (matrix) is counted, and the lines having the largest
number of defects are replaced with the spare lines. This method achieved by memory array reconfiguration
(bad bit exclusion), combined with error correction code techniques, in prospective terabit-scale hybrid
semiconductor/nanodevice memories, as a function of the nanodevice fabrication yield and the micro-to-nano
pitch ratio. The results show that by using the best (but hardly practicable) reconfiguration and block size
optimization, hybrid memories with a pitch ratio of 10 may overcome purely semiconductor memories in
useful bit density if the fraction of bad nanodevices is below ∼15%, while in order to get an
order-of-magnitude advantage in density, the number of bad devices has to be decreased to ∼2%. For the
simple ‘Repair Most’ technique of bad bit exclusion, complemented with the Hamming-code error correction,
these numbers are close to 2% and 0.1%, respectively. When applied to purely semiconductor memories, the
same technique allows us to reduce the chip area ‘swelling’ to just 40% at as many as 0.1% of bad devices.
We have also estimated the power and speed of the hybrid memories and have found that, at a reasonable
choice of nanodevice resistance, both the additional power and speed loss due to the nanodevice subsystem
may be negligible.

Unsteady MHD Flow Past A Semi-Infinite Vertical Plate With Heat Source/ Sink:...IJERA Editor
In the present paper a numerical attempt is made to study the combined effects of heat source and sink on unsteady laminar boundary layer flow of a viscous, incompressible, electrically conducting fluid along a semiinfinite vertical plate. A magnetic field of uniform strength is applied normal to the flow. The governing boundary layer equations are solved numerically, using Crank-Nicolson method. Graphical results of velocity and temperature fields, tabular values of Skin-friction and Nusselt are presented and discussed at various parametric conditions. From this study, it is found that the velocity and temperature of the fluid increase in the presence of heat source but they decrease in the presence of heat absorption parameter.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

II. MATHEMATICAL FORMULATION
We consider a steady laminar flow of a viscous
incompressible fluid past an infinite vertical
porous flat plate. Introduce a coordinate system (x,
y) with x -axis along the length of the plate in the
upward vertical direction and y -axis normal to the
plate towards the fluid region. The plate is
subjected to a constant suction parallel to y -axis.
The viscous dissipations of energy are assumed to
be negligible for the study. Since, the plate is
infinite in length all the fluid property except
possibly the pressure remain constant along the
x -direction. The fluid property variation with
temperature is limited to density variation only and
the influence of variation of density with
temperature is restricted to the body force term
only, in accordance with the Boussinesq
approximation. Under boundary layer and
Boussinesq approximations, the equations
governing the steady laminar two dimensional free
convective flow with medium concentration in
presence of Soret and Chemical reaction effects

IV. CONCLUSION
In this Paper we discuss the radiation and
chemical reaction effects on MHD free convection
flow of a uniformly vertical porous plate with heat
generation. The expressions for the velocity,
temperature and concentration distributions are
the equations governing the flow are numerically
solved by perturbation technique.
The velocity increases with the increase of
permeability parameter K.
The temperature decreases with the increase of
radiation parameter R.
The concentration decreases with the increase
of chemical reaction parameter C.
The Sherwood increases with the increase of
Chemical Reaction (Ch), but it takes the reverse
action.
The Sherwood decreases with the increase of
Schmidt number (Sc), but it takes the reverse
action.
The Skin-friction increases with the increase
Permeability Parameter (K).
The Skin-friction decreases with the increase of
Chemical Reaction (Ch).
