“Test rig on Eddy current braking system” is a very great innovation on its own and is specially made for the purpose
to stop the wheel in minimum time. Brakes are the crucial components in any mobile system which are generally used to stop
the motion of any mobile. Such type of component must be checked by using the highly accurate methodology in order to
access its functional performance in advance. The inspection methodology of brakes should be accurate with less time
consuming procedure for its inspection. This test rig will check the brake in the least time which leads to a reduction of nonproductive
time and improves brake efficiency.
NEW APPROACH FOR COMPUTER-AIDED STATIC BALANCING OF TURBINES ROTORSBarhm Mohamad
The balancing operation consists in improving the distribution of the rotor masses so that the free centrifugal forces around the rotor axis, imposed by the manufacturer, do not exceed the tolerances allowed by the standards. In this paper we propose algorithms for the distribution of the turbine blades from data from an electronic scale which allows to measure the static moment of the blades, these algorithms aim to find the correction weight and the angle of position of the correction mass, we also propose a simulation of the distribution of the blades of a turbine to get an idea on the assembly. This operation is necessary in the case of a repair of the rotors or in the assembly of the new flexible rotors. Using a MATLAB calculation code.

Fabrication of Prototype Model of Infrared Sensor Based Regenerative Braking...IJMER
The objective of this paper is to stored the kinetic energy dissipated in the brakes to accelerate
the vehicle. This project is based on prototype model of Regenerative braking system using electromagnetic
clutch. Regenerative braking results in an increase in energy output for a given energy input to a vehicle,
the efficiency is improved. The amount of work done by the engine of the vehicle is reduced, in turn
reducing the amount of prime energy required to propel the vehicle. In order for a regenerative braking
system to be cost effective the prime energy saved over a specified lifetime must offset the initial cost, size
and weight penalties of the system. The energy storage unit must be compact, durable and capable of
handling high power levels efficiently. The energy can be directly provided to dynamo itself to generate
current and will be displayed on the Ammeter installed in the set up. This set up also consists of an Infrared
Sensor which helps to prevent the frequency of accidents increasing due to inefficient braking system and
therefore can be considerably avoided using IR sensors. The vehicle instantly stops as any object appears
in front of it where IR Sensors are installed.

Optimization of Modified Sliding Mode Controller for an Electro-hydraulic Act...IJECEIAES
This paper presents the design of the modified sliding mode controller (MSMC) for the purpose of tracking the nonlinear system with mismatched disturbance. Provided that the performance of the designed controller depends on the value of control parameters, gravitational search algorithm (GSA), and particle swarm optimization (PSO) techniques are used to optimize these parameters in order to achieve a predefined system’s performance. In respect of system’s performance, it is evaluated based on the tracking error present between reference inputs transferred to the system and the system output. This is followed by verification of the efficiency of the designed controller in simulation environment under various values, with and without the inclusion of external disturbance. It can be seen from the simulation results that the MSMC with PSO exhibits a better performance in comparison to the performance of the similar controller with GSA in terms of output response and tracking error.
Sensor fault reconstruction for wind turbine benchmark model using a modified...IJECEIAES
This paper proposes a fault diagnosis scheme applied to a wind turbine system. The technique used is based on a modified sliding mode observer (SMO), which permits the reconstruction of actuator and sensor faults. A wind turbine benchmark with a real sequence of wind speed is exploited to validate the proposed fault detection and diagnosis scheme. Rotor speed, generator speed, blade pitch angle, and generator torque have different orders of magnitude. As a result, the dedicated sensors are susceptible to faults of quite varying magnitudes, and estimating simultaneous sensor faults with accuracy using a classical SMO is difficult. To address this issue, some modifications are made to the classic SMO. In order to test the efficiency of the modified SMO, several sensor fault scenarios have been simulated, first in the case of separate faults and then in the case of simultaneous faults. The simulation results show that the sensor faults are isolated, detected, and reconstructed accurately in the case of separate faults. In the case of simultaneous faults, with the proposed modification of SMO, the faults are precisely isolated, detected, and reconstructed, even though they have quite different amplitudes; thus, the relative gap does not exceed 0.08% for the generator speed sensor fault.
DESIGN AND FABRICATION OF SERIAL MANIPULATOR WITH HYBRID CONTROL THEORYAbhishek Mittal
A serial manipulator consists of a fixed base, a series of links connected by joints, and ending at a free end carrying the tool or the end-effector. In contrast to parallel manipulators, there are no closed loops. By actuating the joints, one can position and orient the end-effector in a plane or in three-dimensional (3D) space to perform desired tasks with the end-effector.
Automation of Fixtures Using Hydraulic Power Pack for a Bogie UnderframeIOSR Journals
In this era of automation technologies manufacturing sectors have placed very high demands on fast and reliable production methods. This work is the evaluation & analysis of the existing clamping system. The current system uses manual clamping of fixtures for holding the work piece in the proper position while welding process is being done on the part. The evaluated system uses hydraulic vertical swing clamps for holding the work piece driven by hydraulic power pack. Thus the new system achieves automatic and simultaneous clamping of fixtures.
This paper deals with a comparative study of circle criterion based nonlinear observer and H∞ observer for induction motor (IM) drive. The advantage of the circle criterion approach for nonlinear observer design is that it directly handles the nonlinearities of the system with less restriction conditions in contrast of the other methods which attempt to eliminate them. However the H∞ observer guaranteed the stability taking into account disturbance and noise attenuation. Linear matrix inequality (LMI) optimization approach is used to compute the gains matrices for the two observers. The simulation results show the superiority of H∞ observer in the sense that it can achieve convergence to the true state, despite the nonlinearity of model and the presence of disturbance.
Detection of Broken Bars in Three Phase Squirrel Cage Induction Motor using F...Dr.NAGARAJAN. S
Finite element method is more precise than the winding function approach, as it is based on the actual geometry of the machine and the machine model can easily be modified in order to study the effect of faults on the machine’s performance. Accurate models of the machine under healthy and faulty conditions are developed. This paper presents simulations of broken bars detection in a three phase squirrel cage induction motor under no load, half load and full load conditions for two and eight broken bars. The analysis is done using MagNet.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Abstract
In this paper, a four bar mechanism
was designed for the specified performance
output for a tractor. In tractor’s plowing is
engaged with the assistance of a hydraulic
cylinder. Looking on the soil hardness the
plowing depth fluctuates that isn't fascinating.
To induce the correct plowing depth an
Electrical control system is introduced. It
consists of hydraulic valve, control unit and also
the angular sensor. The control system helps to
regulate the plowing depth accurately. The
device measures the position of pivot and offers
feed back to the system. Thus a sturdy, reliable
and safe link mechanism is developed to
measure the angular motion of the pivot. The
main focus of this paper is to analyze

1. Introduction
The kinematic structural studies have a
very important role within the design and synthesis
of mechanisms. The main focus of this paper is to
analyze Dimensional synthesis is performed
supported Freudenstein’s Equation. This paper
focuses on presenting the event of a four bar link
mechanism that is employed to measure the angular
position of pivot. As per the desired task the
dimension of links was developed on the idea of
dimensional synthesis using Freudenstein’s
equation and Chebechev’s equation. The Adams
simulation is dead on the idea of those dimensions.
Also, compare these dimensions with existing
dimensions used for previous task.
Apart from this linkage mechanism for a
similar, we are able to use gear, timing belt and
pulley etc. However, these mechanisms aren't
reliable and also the producing value is relatively
high. The approximate lifetime of the angular
sensor is thirty million cycles. Therefore, the
mechanism, that is to be coupled to the device,
ought to have an honest lifetime while not
undergoing any wear and tear, corrosion etc.
whereas comparison to gear and timing belt and
pulley mechanism the angular sensor can provide
additional accuracy because it is coupled to linkage
mechanism. Backlash error is that the main
complications of mechanisms like spur and bevel
gears. Most allowable error of angular sensor is
1%. Slippage error is that the major hindrance in
timing belt and pulley, whereas comparison to
different mechanisms linkage mechanism offers
readings that are additional correct. Advantages to
the approach of design of link mechanism can cut
back the producing value. Another advantage of
linkage mechanism is that the cross load like
tangential, radial and axial load functioning on
gears together with spur and bevel, timing belt and
pulley, intermediate gear are additional comparison
to linkage mechanism. Moreover, the weight of the
linkage mechanism is negligible. Whereas
manufacturing sturdy, reliable and safe link
mechanism are the vital goals of this paper.
Therefore, the accuracy of the angular sensor is
more whereas comparison to gear and belt drive
mechanisms.
2. Problem Statement
Angular sensor is employed to measure
the angular position of an outsized pivot having
diameter of 80 mm. The sensor is placed at a
distance of 80 mm from the pivot. This pivot is
coupled to the smaller shaft by suggests that of a
coupling. The pivot is experiencing explosive jerk
or lateral movement. Tractor would like low
sensitivity for output voltage once tiller in higher
position and wish an outbreak of sensitivity at the
time of plowing. The position of the pivot and also
the sensor shaft is parallel.

Fig.1 Problem statement
Main complication during this application
is that the pivot is in giant in size and an explosive
jerk or lateral movement of the pivot. So an
innovative four bar linkage mechanism is to be
developed. A steel casing is provided to safeguard
this from environmental variations.
3. Project Concept
Fig.2 Concept of 4 bar linkage mechanism
A four bar mechanism is developed from
Freudenstein’s equation by using Matlab. One end
of the linkage mechanism is engaged to the angular
sensor and different end is coupled to the pivot of
80 mm diameter. The massive pivot can move to
and fro at 120 degree and corresponding angle is
measured by the angular device. One end of the
link mechanism can't be connected on to the pivot
as a result of its giant size. To avoid this
complication a clamp is mounted to the pivot.
Length from the centre of the pivot to the clamp is
taken into account joined link; as a result of link
mechanism is revolved with relevancy a hard and
fast position. Second link accommodates 2
elements. Each elements can moves in x-y plane
and live the angular motion of pivot accurately by
the device. Moreover, if any explosive jerk
happens, the second half can compensate the jerk.
This can be attainable as a result of the speed of
rotation of pivot is incredibly small.
4. Literature Review
To reduce the human effort the
mechanisms and machines are used since ancient
time itself. This influenced all aspects of human
society throughout the commercial revolution. In
easy words, a mechanism is an assemblage of rigid
links connected by joints, which permit relative
motion between the connected links. The output
link is touched with relevancy the input link of
mechanism. The Watt’s straight-line linkage is that
the one amongst the proverbial mechanism was
designed by applied scientist employed in the
double acting external-combustion engine [1].
Mechanism analysis and design was done
diagrammatically within the beginning of
nineteenth century. Throughout the time of 1950’s
computers and algorithms were used for computing
a similar. Freudenstien realized the influence of
computers for the planning and analysis of
mechanisms and machines [2]. Moreover, his
analytical approach dead fitted the new computer
technologies. Finally design of a four-link
mechanism one numerical example is presented [3,
4].
Several investigations are disbursed
supported the structural synthesis and analysis of
linkages and different mechanisms [5, 6]. Earlier
pure intuition and inspection graph theory were the
methods utilized for structural synthesis of
kinematic chains. Human error is happens all told
these studies as a result of visual inspection [7].
This human error is affected in each result and can't
be dominated out. Thus absolutely processed
technique is developed to eliminate the human
error. This helps the designers to get the results
quickly. Chebyshev spacing of precision points is
performed to scale back the structural error [8].
And additionally the dimensional synthesis of
Freudenstein equation can minimize the structural
error [9, 10, 11].
A Generalized Performance Sensitivity
Synthesis Methodology for Four Bar Mechanisms
printed in an exceedingly journal explained the
term sensitivity constant. Erdman and Faik outlined
and derived the sensitivity constant [12]. This can
be a mathematical expression within which tiny
variation within the mechanism parameters like
link length build modification within the output
variable. This parameter helps for analysis of error
in four bar link mechanism.
In nowadays, link mechanisms are
employed in several devices and kind of gadgets-in
automotive fields like steering and braking
systems, fluid pumps etc. Medical applications like
artificial prosthetic knees, laparoscopic surgical
tools, different medical devices, and applications in
spacecraft’s. Now, these link mechanisms are
unified with sensors, electronics and control
systems. This results the innovation in micro-
electro mechanical systems (MEMS), robotics.

mechanism whereas comparison to different
strategies. As a result of in Freudenstein’s equation

formulations are easy. Another vital advantage of
Freudenstein’s equation is output angle varies with
by applying totally different transfer functions.

6. Results and Analysis
6.1 Freudenstein’s Equation by using Matlab
Software
In linkage mechanisms, the path generated
by the output link depends on the length of each
links. Hence, predictions of the transfer function of
linkage mechanisms are difficult. Path generation
of output link is calculated with the assistance of
Freudenstein’s equation. Link ratios are relied on
several input parameters. It’ll be terribly valuable
to be able to quickly compute the link ratios. Thus
link ratios are calculated by using Matlab.
Input and output parameters of Freudenstein’s
equation in matlab as follows:
Initial position of input link, φ1= 0°;
Initial position of output link, ψ1= 60°;
Range of variation of input link, Δφ = 120°;
Range of variation of output link, ΔΨ = 90°;
Function, Y= exp(X)
Output in terms of lengths:
Length of the input link, a1 = 56.72 mm;
Length of connecting link, a2 = 64.79 mm;
Length of the output link, a3 = 55.30 mm;
Length of the frame, a4 = 80 mm
The start and final value of X is taken as 1
and 4 respectively. Moreover, by using
Chebechev’s formula, three precision points are
calculated and corresponding input and output
angles are obtained. By assumptive vary of input
and output, the subsequent result table are going to
be obtained.

6.2 Adams Simulation
The link ratios obtained from the Matlab
is simulated in Adams. Input angle is touched from
zero to 120˚ and corresponding output angle is
premeditated. The link ratios obtained from Matlab
is important as a result of the path generated by the
output link is predicated on the link ratios. The
output link generates exponential path suggests that
initial stage link can provide low sensitivity and
later output link motion can generate high
sensitivity. Theoretical and simulation leads to

6.3 Structural Error Analysis
Structural error is outlined because the
distinction between the actual mathematical
function and performance created by the
synthesized linkage .Value of function is obtained
from Matlab and values of synthesized linkage are
collected from Adams simulation. The results from
Adams simulation is thus near the values got from
Matlab. This result's acceptable as a result of
structural error is a smaller amount than 1%.The
output link of synthesized four bar link mechanism
follows the similar graph of actual function. The
percentage error is shown within the table below.
