Silicone rubber has emerged as an alternative material for porcelain insulators and glass insulators on a
high voltage transmission because it is lightweight, so it helps in planning the structure of the transmission tower.
However, due to the cost of production of silicone rubber insulators are expensive and it is less resistant to climate
change, it has not been used extensively as in Indonesia. One method to get silicone rubber insulator that is cheap is
to mix it with other materials in the form filler that is inexpensive and easy to obtain as fly ash of coal because this
material has a particle size that is very fine and its contents are materials that have been and are being investigated as
filler of silicone rubber. This paper describe about the research that has proven the feasibility of fly ash as filler for
silicone rubber. The results of this study is the tensile strength of silicone rubber increased proportional to the
increase of fly ash content on silicone rubber, but lowers elongation-to-break of the silicone rubber. Furthermore, the
electrical properties, namely the dielectric strength of silicone rubber will increase with the addition of filler (fly ash),
where the greatest dielectric strength on the composition of the filler (fly ash) 40%. As for the relative permittivity is
increased with the addition of filler (fly ash) to silicone rubber by 50%. And the silicone rubber surface resistance will
increase with the addition of filler (fly ash).
Fabrication and tensile property analysis of a composite laminate with differ...eSAT Journals
Abstract Composites play a vital role in aerospace, land transportation and consumer goods due to their high specific strength and stiffness leading to reduction in the mass of moving objects. Some of the important aerospace hardware such as rocket motor casing makes extensive use of carbon fiber reinforced polymer(CFRP). In this present investigation E-Glass epoxy laminates were used. The tensile properties for various Diameter holes were determined and compared with the actual strength of the material without any hole. Results indicate that because of the increase in diameter of the hole the tensile strength of the material is decreasing. Keywords: CFRP, E-Glass, Epoxy, Tensile strength.
EXPERIMENTAL STUDY ON THE PERFORMANCE OF HYBRID FIBRE REINFORCED CONCRETE AT ...AM Publications
The main objective of this study is to understand the fundamental behaviour of FRC when it is exposed to elevated temperatures. However, rather than relying on one type of fibre, this study proposed of mixing two different types of fibre in concrete which will then be exposed to elevated temperatures from normal temperature i.e. 27 °C (room temperature) to 200°C, 400 °C and 600 °C for one hour and cooled to room temperature before testing. The two types of fibres used, steel and Recron 3s (polyester) fibres, have different characteristics. The study is mainly focused on the experimental work. Concrete mixes prepared are without fibre, with either or both steel fibre and Recron 3s fibres. Dosage of steel fibre is 1% by volume of concrete and Recron 0.1% by volume of concrete. The study deals with the comparison of residual strength of hybrid fibre reinforced concrete with fibre reinforced concrete. Experimental work was carried out to study the impact of elevated temperatures on the compressive strength, tensile strength and ultrasonic pulse velocity.

Abstract
The requirement of light weight and high strength materials are ever increasing in the industry. Lot of research is going on worldwide for improvement of mechanical properties of light weight non-metallic composites. Researchers are trying to meet the industrial requirements by modifying properties of composite materials by making nanocomposites. Nanocomposites are formed by mixing two or more dissimilar materials and adding nanoparticles in order to control and develop new and improved materials and their properties. The properties of composites depend not only upon the individual components used but also upon the morphology and the interfacial characteristics of the ingredients. This novel feature forms the basis of hypothesis to be investigated.
In the investigation for high strength materials, laminates of epoxy resin and nanoparticles of Al2O3 as filler are used with Aramid fibre, hybrid of carbon and aramid fibre as reinforcement are produced. Nanoparticles of Al2O3 of 20-30nm size are first dispersed in methanol by mechanical stirring. The solution is further sonicated for effective dispersion of nanoparticles. The mixture of methanol and Al2O3 nanoparticles are mixed in preheated Epoxy resin and mechanically stirred. During mixing some of the methanol is evaporated. Further, the remaining methanol is removed by heating and drying. Then, Hardener is mixed with the mixture of epoxy- Al2O3 and laminates are prepared. The laminates are cut to the required size of test samples for mechanical tests. It is observed that the mechanical properties are improved with the addition of nanoparticles of Al2O3.

AXIAL CRUSHING OF GFRP FRUSTA: EXPERIMENTAL AND NUMERICAL ANALYSISIAEME Publication
Experimental and numerical analysis of the axial crushing of glass fiber
reinforced polymer (GFRP) frusta tubes are presented in this study. The frusta tubes
are fabricated from plain woven C-glass fabric bonded with the epoxy system LY-556
resin and HY951 hardener. Two semi-apical angles 5º and 10º with 95mm height and
1.4mm wall thickness were studied under quasi-static crush conditions. All specimens
showed progressive damage in region starts from the contact with the crushing
crosshead and spreads about 7mm ahead the crushing surface. Mix of tiny debris and
strip shaped chunks are generated in the crushing zone. The debris is accumulated as
outside or inside fronds formation. The strip shaped chunks are generated
peripherally due to shear effects by crusting from the frusta body and crack growth at
the outmost crush zone points from the crushing surface. The 5º frusta showed better
crashworthiness performance than 10º frusta. Simulation results showed good
agreement with the experimental findings in both collapse mode and energy

erosive work environment, it has become extremely important
to investigate their erosion characteristics. The hybrid
composite consisting of a Epoxy resin reinforced with Eglass
fiber and Si particles was developed. The effect of temperature
on wear rate applied to Si – Epoxy – Eglass polymer composite
has been studied. It has been found that the wear rate increases
as the temperature of carrier media (air) is increased.
Temperature of carrier media is one of the significant factor
influencing the erosion wear. The results were compared with
the plain epoxy composite material. Micrographs of eroded

All these elements have contributed pressures to decrease cement consumption and to intensify lookup in exploring the probabilities of improving strength, sturdiness and corrosion discount via the use of pozzolonas as supplementary cementing materials. Fibre bolstered concrete FRC is a fibre reinforcing cementitious concrete composite, and by way of including discrete brief fibres randomly in concrete it famous many appreciably multiplied engineering residences It is manufactured from kaolin which makes the concrete extra long lasting and ecofriendly. In the current investigation mechanical residences of concrete containing each Fly ash and Metakaolin at a number of combos are studied. For the a range of mixtures of Fly ash and Metakaolin, cubes cylindrical and prism specimens are casted with 1 of fibres and the compression strength, break up tensile energy and flexural energy take a look at consequences are got and in contrast with the traditional combine having 1 fibres.

Abstract The purpose of this study is to evaluation of the mechanical characterisation such as tensile, compression and bending test and to conduct wear test. This study focus on preparation and testing of Polyester resin using glass fibre for different orientation. The Mechanical properties of the polyester changes gradually by changing the layers of fibres and for different orientation of glass fibre the property differs. The laminate is prepared of size 300*300*4mm size and specimens are prepared as per ASTM standard, different layers of glass fibres are one, two and three layers and the orientation of glass fibre is 30o, 60o, and 90o. The glass fibre used is in fabric form. From the results which were obtained we can observed that three layers glass fibre for 90o orientation has improved tensile strength and the compressive strength is found to be more for 600orientation of glass fibre. And the wear rate is also less for three layer of glass fibre for 900 orientations. Keywords: Glass Fibre/Polyesters Composites, Mechanical Characterisation of Polyester, Orientation of Glass Fibre

Mechanical properties as above mentioned nanoiron particles filled with polyester and epoxy nanocomposites were fabricated to assess the possibility of using this filler as a latest material. Functionalization agent as Methacryloxypropyl was used to prepare f-Fe2 O3 nanoparticles. f-Fe2 O3 nanocomposites of mechanical properties were improved with the help of functionalization when compared with nanocomposites of Fe2 O3 Nanoiron particles functionalization favours the composite fabrication with a curing temperature at low as compared to the as-synthesised nanoparticles filled polyester nanocomposites. Mechanical properties carried out are Hardness, Impact strength, Tensile strength, Flexural strength and Compression strength. Mechanical property values increased due to the homogeneous nanoparticle dispersion and chemical bonding between polyester matrix and nanoparticles. After incorporation nanoiron particles into the polyester resin matrix it becomes magnetically harder. Machines generated mechanical property values were compared and analysed with system generated software analysis of variance (ANOVA) values

PEDESTRIAN DETECTION IN LOW RESOLUTION VIDEOS USING A MULTI-FRAME HOG-BASED D...AM Publications
Detecting pedestrians in low resolution videos is a challenging task, due to the small size of pedestrians in the images and the limited information. In practical outdoor surveillance scenarios the pedestrian size is usually small. Existing state-of-the-art pedestrian detection methods that use histogram of oriented gradient (HOG) features have poor performance in this problem domain. To compensate for the lack of information in a single frame, we propose a novel detection method that recognizes pedestrians in a short sequence of frames. Namely, we take the single-frame HOG-based detector and extend it to multiple frames. Our detector is applied to regions containing potential moving objects. In the case of video taken from a moving camera on an aerial platform, video stabilization is first performed to register the frames. A classifier is then applied to features extracted from spatio-temporal volumes surrounding the potential moving objects. On challenging stationary and aerial video datasets, our detection accuracy outperforms several state-of-the-art algorithms.

EFFECT OF SILICON - RUBBER (SR) SHEETS AS AN ALTERNATIVE FILTER ON HIGH AND L...AM Publications
A digital radiography delivers a radiation dose to patients; therefore it poses potential risk to the patients. One effort to reduce dose is carried out using a radiation filter, e.g. Silicone Rubber (SR) sheet. The purpose of this research was to determine the impact of the SR sheet on the high contrast objects (HCO) and the low contrast objects (LCO). The dose reduction was determined from attenuation x-rays before and after using the SR sheet. Assessment of HCO and LCO was observed from CDR TOR phantom at tube voltage of 48 kVp and tube current of 8 mAs. The physical parameter to assess image quality was the Signal to Noise Ratio (SNR) value in LCO. The maximum x-ray attenuation using the SR sheet is 48.82%. The visibility of the HCO remains the same, namely 16 objects; however the LCO slighly decreases from 14 objects to 13 objects after using the SR sheet. The SNR value decreases with an average value of 15.17%.Therefore, the SR sheet as a alternative filter has no effect on the HCO and has realtively little effect on the LCO. Thus, the SR sheet potentially is used for radiation protection in patients, especially on examinations that do not require low contrast resolution.

ANALYSIS ON LOAD BALANCING ALGORITHMS IMPLEMENTATION ON CLOUD COMPUTING ENVIR...AM Publications
Cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet. The elements involved in cloud computing are clients, data center and distributed server. One of the main problems in cloud computing is load balancing. Balancing the load means to distribute the workload among several nodes evenly so that no single node will be overloaded. Load can be of any type that is it can be CPU load, memory capacity or network load. In this paper we presented an architecture of load balancing and algorithm which will further improve the load balancing problem by minimizing the response time. In this paper, we have proposed the enhanced version of existing regulated load balancing approach for cloud computing by comping the Randomization and greedy load balancing algorithm. To check the performance of proposed approach, we have used the cloud analyst simulator (Cloud Analyst). Through simulation analysis, it has been found that proposed improved version of regulated load balancing approach has shown better performance in terms of cost, response time and data processing time.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
