Abstract:

The constrained mechanical systems by quasi-coordinates are more universal
than by generalized coordinates. In this paper, the motion equations of nonconservative
singular mechanical systems by quasi-coordinates in phase space are
studied. The regularization forms of Boltzmann-Hamel equations for general
holonomic and nonholonomic singular mechanical systems are derived. The results
show that the canonical equations expressed by quasi-coordinates and quasivelocities
have a completely single structure, which do not depend on the constraints
or not. The nonholonomic singular mechanical system is a natural extension of the
general holonomic singular mechanical system.

Abstract:

In the world today computer networks have a very important position and most
of the urban and national infrastructure as well as organizations are managed by
computer networks, therefore, the security of these systems against the planned
attacks is of great importance. Therefore, researchers have been trying to find these
vulnerabilities so that after identifying ways to penetrate the system, they will provide
system protection through preventive or countermeasures. SVM is considered as one
of the major algorithms for intrusion detection. One of the major problems is the time
of training and the need to improve its efficiency when it comes to work with large
dimensions. In this research, we try to study a variety of malware and methods of
intrusion detection, provide an efficient method for detecting attacks and utilizing
dimension reduction. Thus, we will be able to detect attacks by carefully combining
these two algorithms and pre-processes that are performed before the two on the
input data. The main question raised in this study is how we can identify attacks on
computer networks with the above-mentioned method. In anomalies diagnostic
method, by identifying behavior as a normal behavior for the user, the host, or the
whole system, any deviation from this behavior is considered as an abnormal
behavior, which can be a potential occurrence of an attack. In this research, the
network intrusion detection system is used by anomaly detection method that uses the
SVM algorithm for classification and SVD to reduce the size. The various steps of the
proposed method include pre-processing of the data set, feature selection, support
vector machine, and evaluation. The NSL-KDD data set has been used to teach and
test the proposed model. In this study, we inferred the intrusion detection using the
SVM algorithm for classification and SVD for diminishing dimensions with no
classification algorithm. And also the KNN algorithm has been compared in
situations with and without diminishing dimensions and the results have shown that
the proposed method has a better performance than comparable methods.

Abstract:

Most of failures in the friction clutches occur due to the excessive heat
generated due to friction between various parts, and this heat causes high
temperatures leading to high thermal stresses. In the present research paper,
numerical simulation had been developed using finite element method to simulate the
thermal behavior of the dry friction clutch. Three-dimensional finite element model
was made and analyzed using ANSYS/Workbench sofware18. The friction clutch
system was firstly modeled mathematically and solved numerically to determine the
transient thermal response of the clutch disc. The two fundamental methods of
uniform wear and uniform pressure are assumed. The applied torque during the
sliding period was constant. The temperature and heat generated were estimated for
each clutch part (pressure plate, clutch disc and flywheel) using heat partition ratio.
The assumptions that are inherent in the derivation of the governing equations are
presented which followed up by the appropriate boundary conditions. The results
show that the maximum temperature values for uniform pressure condition are
greater than those for uniform wear condition. Also, the temperature value increased
with time and approximately reaches the highest value at the middle of the sliding
period when the applied torque is constant with time and then decreased to the final
values at the end of slipping period.

Abstract:

As the world thrives for power in order to strengthen its industrial demands
and economy, traditional power sources are becoming more and more difficult to
fulfill the rising demands. Renewable energy demand in the world whether third
world countries or leading ones of the era, has seen a boost in recent decades.
Photovoltaic and solar energy is an ongoing trend in power system designers,
researchers and companies. As sun is the free source of energy, the world now a days
achieves 30% of its total energy from it. Solar power is sporadic and is not constant,
as solar source at the ground level is extremely reliant on clouds density,
atmospheric conditions with other restrictions. These limitations become a
challenging task for engineers and energy managers to focus the energy constraints
and came up with managing plan in order to produce and manage energy efficiently
in smart grids. This paper focuses on energy constraints of both solar resource and
PV power alongside smart grid energy management.

Abstract:

In this paper we have studied the α -ideals in a 0-distributive lattice. We
have described the α -ideals by two definition and proved that these are equivalent.
We have given several characterizations. They have proved that a lattice L is
disjunctive if and only if each ideal is an α -ideals. We have also included a prime
separation theorem for α -ideals. At the end we have studied the α -ideals in a
sectionally quasi-complemented lattice.

Investigating the behavior of steel structures with honeycomb damper against blast and earthquake loads

Authors:

Navid Farrokhnia,Seyed Mojtaba Movahedifar,

DOI NO:

https://doi.org/10.26782/jmcms.2019.08.00007

Abstract:

Earthquake is one of the most important natural phenomena and humans
have always been trying to control its adverse effects. In the past century, the
development of cities and the high investment in them and many financial and life
losses caused by earthquake and, on the other hand, the ever-increasing advances in
science and technology that allow for more accurate knowledge of the factors causing
the earthquake and how to control it have made humans reduce its financial and life
losses by making suitable and earthquake resistant structures. Today, due to the
increasing growth of terrorist activities, the risk of structures facing blast loads has
also increased. The occurrence of various terrorist incidents in relation to important
structures around the world has caused that in recent years, blast loads become the
focus of special attention. This article examines the connection of steel structures
with honeycomb damper by applying blast and earthquake loads in Abaqus finite
element software. Three frame models with 6, 9 and 13 floors have been considered
for the study. For air blast, 10 Kg of TNT have been used. To apply earthquake
records, seven pairs of accelerograms have been employed. By examining the results
of numerical modeling in Abaqus finite element software, it can be observed that as a
result of applying blast load, the damper could not react. But due to applying
earthquake records, the damper’s behavior was very good so that at the beamcolumn
joint, the highest amount of stress was created in the damper. Considering
that applying the blast loading occurs in less than a few milliseconds and the
structure does not have enough time to react to this load, blast load failure has been
local and sectional.

Abstract:

Alcoholism could be identified through analyzing electroencephalogram (EEG)
signals. Yet, it is difficult to analyze with multi-channel EEG signal since it is
frequently needing long time for execution and complex calculations. The presented
paper proposed 13 optimal channel to feature extraction. Firstly, 1200 recordings
of biomedical signals will be presented for extracting the sample entropy. Statistical
analysis approach will be utilized for the purpose of choosing the best channels for
identifying abnormalities in alcoholics. Secondly four classifiers are applied at the
decision level, Naïve Bayes, SVM, Logistic Regression, KNN, the accuracy was
80.1%,92.5%, 73.7% and 90.3%Respectively, in this study the SVM classifier is more
accuracy .

Abstract:

Currently, hundreds of consumer products in cludelarge-scale nanoparticles;
this enhances the possibility of such particles to be released into water and in result
causesenvironmental and human health issues. In this research, asynthesis of
PolyMethylMethAcrylate (PMMA) nano-membrane for the filtration of nanoparticles
from natural water is demonstrated. Electrospinning technique is deployed for the
synthesis of PMMA nanofibers. The synthesized nanofibers are further optimized by
adding Di-Methyl Formamide (DMF) and acetone that provides elasticity and
increases the exterior area of the nano-membranes. The resultant membrane is
tendbal and instinctivelyrobust enough to resist filtration under high stress. The
synthesized nanofibers are further analyzed and characterized by using spectroscopy
(UV-Vis), Fourier Transform Infra-Red spectroscopy (FTIR) and Scanning Electron
Microscope(SEM).The SEM, UV-vis and FTIR result shows the filtration rate of the
fabricated membrane could capably exclude nanoparticles with different sizes (from
10 to 100 nm in diameter) from a feed solution.

How the Higgs Field Effects the Wave Propagation of Waves as Wavy Resembles a Sine Wave. Why Astronomical Particles have Relationship between Shape (Elliptical) and Orbit (Elliptical).

Abstract:

The space is filled with Higgs fields. As other fields like electric fields or
magnetic fields, Higgs fields are of elliptical shape. Higgs fields are small individual
fields represent a tiny part of space. Every adjacent Higgs Fields have opposite
rotations, the repulsive force makes them to have unique identity for themselves
which makes free space highly stable. Opposite rotation is the reason that any two
Higgs fields do not mingle with each other to form larger field in free space, but
under the influence of ordinary matter like Earth, Higgs fields change their
orientations to be unidirectional to form a larger field called gravity. The larger the
mass, the higher the number of Higgs fields to have unidirectional orientations. The
force carrying particle Higgs Boson is responsible for Higgs field and the force
carrying particle graviton is responsible for gravitational force. The unidirectional
orientations of many small oval shaped Higgs Boson yields the graviton which has
oval shape too. Thus, Higgs Boson and graviton are same force carrying particle
acting differently at different situations. For example, stationary charge gives electric
field where as moving charge gives magnetic field. The phenomenon of both is
basically the same but looks different due to movement. Maxwell realized that the
phenomenon of both is the same with the same force carrying particle but act
differently at different situations. In this paper we will find, why wave propagations of
waves are wavy. We will also find why the shape and orbit of astronomical objects
are of similar pattern – elliptical or oval shape.
