This document discusses the influence of costless nanoparticles on the electric and dielectric characteristics of polyethylene industrial materials. It describes how nanoparticles of clay and fumed silica were added to low density polyethylene (LDPE) and high density polyethylene (HDPE) at various weight percentages. Electric properties like dielectric constant and resistivity were then measured for the pure polymers and nanocomposites using a HIOKI 3522-50 LCR Hi-tester device. The results showed that the dielectric constant generally decreased while resistivity increased as nanoparticle concentration increased. This experimental study demonstrates how costless nanofillers can enhance the electric and dielectric properties of polyethylene for industrial applications.

This document reports on an experimental study that investigated the effects of different types and concentrations of cost-effective nanoparticles on the thermal, electrical, and dielectric properties of polypropylene nanocomposites. Dielectric spectroscopy was used to measure the relative permittivity and loss tangent of polypropylene samples with and without nano-fillers at various frequencies and temperatures. The results showed that the addition of clay or fumed silica nanoparticles in concentrations of 1-10% by weight can influence the dielectric behavior and resistivity of the polypropylene nanocomposites depending on the nanoparticle type, concentration, and temperature of the nanocomposite.
Electrical treeing and partial discharge characteristics of silicone rubber f...IJECEIAES
This article presents a study on electrical treeing performances with its associated partial discharge (PD) and the influence of filler concentration in silicone rubber (SiR) samples which are filled with silicon dioxide (SiO2) and silicon nitride (Si3N4) as nanofillers for electrical tree growth suppression. There are many researches on electrical treeing in SiR with SiO2 nanofillers but none of the publication have reported on Si3N4 nanofillers for suppression of the electrical tree growth. In this study, the treeing experiments were conducted by applying a fixed AC voltage of 10 kV and 12 kV at power frequency of 50 Hz on unfilled SiR, SiR/SiO2, and SiR/Si3N4 nanocomposites with different filler concentrations by 1, 3, and 5 weight percentage (wt%) and the treeing parameters were observed with its correlated PD patterns. The outcome from this study found that the SiR/Si3N4 nanocomposites were able to withstand the electrical treeing better than the pure SiR or SiR/SiO2 nanocomposites. Furthermore, the increase in filler concentration improved the electrical tree performances of the nanocomposites. This finding suggests the Si3N4 can be used as filler in polymeric insulating materials for electrical tree inhibition. Meanwhile, the PD activity shows increment when the tree progresses thereby indicating correlation in both parameters which can be as key parameter for monitoring unseen treeing in non-transparent samples.

The effects of ZnO particles on the color homogeneity of phosphor-converted h...IJECEIAES
Color homogeneity is one of the goals to continuously improve WLED. Among the methods for enhancing the color uniformity of WLEDs, improving scattering in phosphor layer is considered to be the most effective. In this paper, ZnO is used for that purpose. The results show that ZnO particle size significantly affects scattering in the phosphor layer, which is a vital factor to analyze scattering, scattering sand surface, scattering coefficient and scattered phase function C sca (D, λ), μ ( λ ) and ρ(θ, λ). In addition, the concentration of ZnO was also analyzed with values from 2% to 22%. Color homogeneity depends not only on size but also on the concentration of added ZnO. Therefore, color homogeneity control is the control of ZnO size and concentration. The proposed result is 10% ZnO for the highest lumen of LED. With 14% and 500 nm of ZnO particles, ΔCCT reaches the lowest. Depending on the production needs, manufacturers can choose the most appropriate way. However, with both required lumen and ΔCCT, 14% ZnO is suitable for ZnO sizes. sca

Flexible PVDF thin film as piezoelectric energy harvesterjournalBEEI
This aim of this paper is to study the potential of Polyvinylidene Fluoride (PVDF) polymeric piezoelectric film as an energy harvester for daily application use. PVDF offers several advantages over other piezoelectric materials such as high chemical strength and stability, high piezoelectric properties and biocompatible. Several investigations were carried out in this project which comprises of simulation, functionality test and application test. For functionality test, the highest voltage produced for a single film PVDF is 0.368 V which charges up a capacitor to 0.219 V in one minute. The highest voltage produced by multiple PVDF films is 1.238 V by stacking 10 films of PVDF in parallel which charges up to 0.688 V in one minute. For application test, 5 pieces of PVDF films were attached to a glove to generate some voltage during fingers bending activity. The highest output voltage recorded is 0.184 V which stores 0.101 V in a capacitor after 200 times of hand bending and releasing. As a conclusion, PVDF has a good potential as an alternative energy for daily application use. Combination of PVDF energy harvester system with proper power optimization circuit will open up rooms of research opportunities in energy harvester system with promising prospect in self-powered wireless electronics devices for Internet of
Things application.

Color uniformity is one of the essentials for the on-going development of WLED. To achieve a high color uniformity index, increasing the scattering events within the phosphor layers was reported to be the most efficient method and in this article, ZnO is the chosen material to apply in this method. After analyzing the scattering properties through the scattering cross-section , scattering coefficient and scattering phase function , the which outcomes comfirm that ZnO can enhance the scattered light in the phosphor layers. Moreover, the findings from the study of ZnO concentration from 2% to 26% suggest that color uniformity also depends on the fluctuation of ZnO concentration, therefore, to control color uniformity the focus should be implied on both size and concentration of ZnO. The experimental results from this research show that the luminous flux of WLED is at the peak if the concentration of ZnO is at 6%, and when the concentration of ZnO is at 18% and has 100 nm particles size, the ΔCCT reaches the lowest level. The final choice should be based on the desired characteristic of WLEDs, however, if the WLED need to excel in both luminous flux and ΔCCT then 6% ZnO concentration with particles size from 100 nm-300 nm is the optimal choice.
Breakdown characteristics of polyethylene/silicon nitride nanocompositesTELKOMNIKA JOURNAL
Silicon nitride (Si3N4) has been utilized as a nanofiller in polymeric insulation due to its good characteristics in both electrical insulation and thermal conduction properties. In this work, a comparative study was performed between unfilled polyethylene and polyethylene containing different amounts of Si3N4 nanofiller. The study showed that the low density polyethylene (LDPE) added with 15 wt% of Si3N4nanofiller could have higher breakdown strength compared to equivalent LDPE with 10 wt% of Si3N4nanofiller. Morphological characterizations of the nanocomposite samples were performed using field emission electron microscopy (FESEM) and the results showed that the breakdown performance of the investigated materials were affected by the agglomeration of Si3N4 nanoparticles.

The chromatic homogeneity and luminous efficiency are two crucial elements for determining a high-quality phosphor-converted LEDs (pc-LEDs). Thus, this paper provides essential information in choosing the particles to enhance lighting properties of high performance pc-LEDs. Scattering enhancement particles (SEP) such as CaCO 3 , CaF 2 , SiO 2 , and TiO 2 , are combined with yellow phosphor Y 3 Al 5 O 12 :Ce 3+ and applied to the lighting devices. Initially, optical simulations are carried out with the support of LightTools program. Next, the Mie-theory is applied to calculate and confirm the results. The calculation subjects are SEPs scattering properties within the band 455 -595 nm. The scattering results of TiO 2 suggest it is the optimal choice for pc-LEDs color quality in comparison to the other SEPs; however, it causes the luminous flux to decrease significantly along with the increase in its concentration. Besides, with the addition of SiO 2 grains, we can accomplish higher lumen output at all particle sizes. Meanwhile, the application of 30% CaCO 3 can decreas the CCT deviation by 620 K making CaCO 3 the potential particle to be selected for chromatic quality and light output enhancement of pc-LEDs.

The adhesive strengths of Norland 68 and Dymax 921 gel bonded to polystyrene targets were tested at cryogenic temperatures using a dynamic mechanical analyzer. A sample preparation method was developed involving gluing a polystyrene loop to a strip. Testing found that the interfacial bond strength between the adhesives and polystyrene increased as temperature decreased. However, results had some scatter. Further refinement of the sample preparation is needed to improve consistency in measuring the adhesive strengths at cryogenic temperatures important for connecting cryogenic targets to support stalks.
This document discusses two designs of microstrip patch antennas. Design 1 is a rectangular microstrip patch antenna that achieves a 13.1% bandwidth. Design 2 is a gap-coupled reduced size rectangular microstrip patch antenna that achieves an enhanced 20.5% bandwidth through the use of parasitic patches placed along the edges of the fed rectangular patch. Simulation results show that Design 2 provides both an improvement in bandwidth and directivity over Design 1.
The Effect of Plasma-Treated Boron Nitride on Partial Discharge Characteristi...IJECEIAES
Power supply reliability is a key factor in a country economic stability. It is contributed by the reliable power distributor via transmission lines, overhead or underground cables. However, the power cables and accessories are always exposed to pre-breakdown phenomena known as partial discharges (PD) which commonly occur in microvoids, defects or protrusions inside the insulation.To improve the performance of the cable insulation against PD, nanofillers are added into the insulating materials. However, to achieve superior performance of PD resistance, the nanofillers must be homogeneously dispersed into the polymer matrices withtightly bonded interfacial zones. Therefore, this could be achieved by employing method of surface functionalization by using cold atmospheric plasma to strengthen the filler/polymer interfaces. In view of foregoing, this study investigated the effects of surface treated boron nitride (BN) nanoparticles in Low Density Polyethylene (LDPE) on the PD characteristics by following CIGRE Method II at 7 kVrmsapplied voltage. The phase resolved PD characteristics were performed. The results revealed that by treating the nanofillers with cold plasma, the PD resistance of LDPE were highly achieved compared with the untreated BN nanofillers.
EXPERIMENTAL INVESTIGATIONS ON EFFECTIVENESS OF ACOUSTIC MATERIAL AS THERMAL ...ijmech
Sound pollution is big problem now-a-days and it causes many health issues. Soundproofing can be used to mitigate the effect of sound pollution, but it adds to the building cost. However, acoustic materials have low thermal conductivity and they may result in saving due to reduced use of electrical energy for heating/cooling of buildings. In the present work, the effectiveness of a commercially available acoustic material, made of Compressed Wood Fiber Cement Composites with a backing of Anti vibration Pad, as a thermal insulator is experimentally investigated. A CAD model of anti-vibration pad material was developed by scanning it with micro CT, converting grey scale data into binary scale by CTan software and extracting 3D- Model from binary data by using Scan IP software. The CAD model was imported into ANSYS workbench for determining thermal conductivity of the anti-vibration pad, which was experimentally validated. The thermal conductivity of composite material was then calculated by Fourier equation. A comprehensive CAD model of anti-vibration pad, composite material and brick-and-mortar wall was used to simulate the variations in room temperature with ambient temperature for one calendar year. The results show that acoustic insulation material also serves as a thermal insulator keeping the room nearly constant with varying ambient temperature

Performance of high power light emitting diode for various zinc oxide film th...eSAT Journals
Abstract Oxide ceramic materials have attractive features either as filler or substrate materials in electronic packaging. Consequently, ZnO thin film for various thicknesses was prepared over Al substrates by RF sputtering and used as heat sink for high power LED. The thermal transient curve of device under test (DUT) was recorded for five boundary conditions. Rise in junction temperature (TJ) was measured and observed low value (54.4°C) for 200 nm ZnO thin films at 350 mA. The difference in junction temperature rise (ΔTJ) was observed as 7.46 °C at 700 mA when compared to bare Al substrates. The total thermal resistance (Rth-tot) of the DUT was low for 200 nm ZnO thin film coated Al substrates. AFM images were used to evaluate the surface roughness factors and their influence on thermal resistance. As expected, the surface roughness, grain size and peak-valley distance were strongly influenced the heat flow. Index Terms: ZnO thin film, thermal interface material, LED, thermal resistance, surface roughness
IRJET- Experimental Study on Strength of Concrete Containing Waste Materials ...IRJET Journal
This document presents the results of an experimental study on the strength of concrete containing waste materials like brick kiln dust and sawdust, as well as nano silica. Concrete cubes were made by partially replacing fine aggregate with these wastes and cement with nano silica. Testing showed that replacing 25% of fine aggregate with brick kiln dust and 10% with sawdust increased compressive strength compared to normal concrete. Compressive strength also increased with the addition of 1% nano silica compared to a control sample without nano silica. The study aims to reduce environmental pollution from waste and costs of concrete construction through the use of industrial byproducts.

This document discusses warpage of microelectronic packages. It begins with an introduction to the importance of controlling warpage, especially in package-on-package configurations where tight warpage specifications are required. The key factors that influence warpage are identified as the die size/thickness, substrate properties and thickness, and underfill material properties. The document then examines warpage fundamentals using the bimetallic strip theory in 2D and finite element modeling in 3D. It identifies glass transition temperature, coefficient of thermal expansion, viscosity, and filler content as important underfill properties for controlling warpage. Solutions for reducing warpage through underfill design and other techniques are proposed.
A Study on Thermal behavior of Nano film as thermal interface layerIJASCSE
Increase in thermal design power and re-duce in manufacturing cost of the processor chip has pushes the need for high performance and durable test fixture design in future. Test fixture with efficient themal management has lowest resistance possible to maintain the accuracy of the device temperature when it makes contact with processor chip’s silicon during test. High thermal conductivity and mechanical relia-bility of text fixures are desired for high volume test environment. Nano film materials such as Aluminum Titanium Nitride (AlTiN), Titanium carbide (TiC), Ti-tanium on Titanium nitride (Ti on TiN), Titanium ni-tride on Titanium (TiN on Ti) and Aluminum(III) Ox-ide (Al2O3) are coated over copper substrates by Fil-tered Cathodic Vacuum Arc (FCVA) deposition method and tested for their thermal conductivity behavior for high volume test (HVM) environment. Thermal con-ductivity of the prepared films is tested by using the ASTM 5470 Thermal Interface Material (TIM) Tester. Titanium on Titanium nitride (Ti on TiN) and Alumi-num (III) Oxide (Al2O3) observed with highest thermal conductivity of 117.68 W/mk and 128.34 W/mk respec-tively among the prepared nano thin films. Thickness of the film and stack configuration influenced the thermal conductivity of the prepared film.
Increase In Electrical And Thermal Conductivities Of Doped Polymers Dependent...IOSR Journals
Most Polymers do not possess natural intrinsic properties that will be enough for them to be used as semi- conductors. In the world trend of industrial growth where polymers seem to be replacing all semi-conductors because of their availability, durability, recyclability and reduced cost, attention is being strongly given to their improvement them for this essential function hence the need for this research.Eight samples each of four polymers; polyethylene (PE), polystyrene (PS), poly propylene (PP),nylon 66 were prepared by doping with different concentrationsof graphite to enhance their electrical and thermal conductivities, considering the fact that they are of different intrinsic properties. The samples were testedfor their electrical and thermal conductivities.It was evident that as the concentration of the graphite dopantincreases, the electrical and thermal conductivities of all the polymers increased although not at the same rate.The most interesting fact is that all polymers that showed highly favorable results in electrical conductivity, showed the least for thermal conductivities which can be attributed to their intrinsic properties.

Further microstructural characterization is needed to understand interactions between nano-materials in concrete mixtures.
Character recognition of kannada text in scene images using neuralIAEME Publication
Character recognition in scene images is one of the most fascinating and challenging
areas of pattern recognition with various practical application potentials. It can contribute
immensely to the advancement of an automation process and can improve the interface
between man and machine in many applications. Some practical application potentials of
character recognition system are: reading aid for the blind, traffic guidance systems, tour
guide systems, location aware systems and many more. In this work, a novel method for
recognizing basic Kannada characters in natural scene images is proposed. The proposed
method uses zone wise horizontal and vertical profile based features of character images. The
method works in two phases. During training, zone wise vertical and horizontal profile based
features are extracted from training samples and neural network is trained. During testing, the
test image is processed to obtain features and recognized using neural network classifier. The
method has been evaluated on 490 Kannada character images captured from 2 Mega Pixels
cameras on mobile phones at various sizes 240x320, 600x800 and 900x1200, which contains
samples of different sizes, styles and with different degradations, and achieves an average
recognition accuracy of 92%. The system is efficient and insensitive to the variations in size
and font, noise, blur and other degradations.
1) The document discusses why management systems often fail in organizations. It identifies several common root causes of failure, including a lack of strategic adoption of standards to meet organizational needs and gaps, poor knowledge of how to effectively implement management systems, and treating systems as just documentation rather than integrating them into daily operations.
2) Additional causes are listed as not establishing clear, measurable objectives aligned with organizational vision; excluding financial functions from management systems; failing to follow established procedures; and treating management system audits as compliance checks rather than opportunities for improvement.
3) The author argues that for management systems to succeed, organizations must adopt them proactively to address their own needs, integrate systems into all functions and decision making, and
This document presents a new integrated bridgeless PWM power converter for power factor correction. The proposed converter integrates a bridgeless boost rectifier with an asymmetrical pulse-width modulation half-bridge DC-DC converter. This eliminates the need for a full-bridge diode rectifier, reducing conduction losses. Zero-voltage switching of the power switches also reduces switching losses. Experimental results from a 250W prototype show the converter achieves 93.0% efficiency and near unity power factor.

The chromatic homogeneity and luminous efficiency are two crucial elements for determining a high-quality phosphor-converted LEDs (pc-LEDs). Thus, this paper provides essential information in choosing the particles to enhance lighting properties of high performance pc-LEDs. Scattering enhancement particles (SEP) such as CaCO 3 , CaF 2 , SiO 2 , and TiO 2 , are combined with yellow phosphor Y 3 Al 5 O 12 :Ce 3+ and applied to the lighting devices. Initially, optical simulations are carried out with the support of LightTools program. Next, the Mie-theory is applied to calculate and confirm the results. The calculation subjects are SEPs scattering properties within the band 455 -595 nm. The scattering results of TiO 2 suggest it is the optimal choice for pc-LEDs color quality in comparison to the other SEPs; however, it causes the luminous flux to decrease significantly along with the increase in its concentration. Besides, with the addition of SiO 2 grains, we can accomplish higher lumen output at all particle sizes. Meanwhile, the application of 30% CaCO 3 can decreas the CCT deviation by 620 K making CaCO 3 the potential particle to be selected for chromatic quality and light output enhancement of pc-LEDs.

The adhesive strengths of Norland 68 and Dymax 921 gel bonded to polystyrene targets were tested at cryogenic temperatures using a dynamic mechanical analyzer. A sample preparation method was developed involving gluing a polystyrene loop to a strip. Testing found that the interfacial bond strength between the adhesives and polystyrene increased as temperature decreased. However, results had some scatter. Further refinement of the sample preparation is needed to improve consistency in measuring the adhesive strengths at cryogenic temperatures important for connecting cryogenic targets to support stalks.

The Effect of Plasma-Treated Boron Nitride on Partial Discharge Characteristi...IJECEIAES
Power supply reliability is a key factor in a country economic stability. It is contributed by the reliable power distributor via transmission lines, overhead or underground cables. However, the power cables and accessories are always exposed to pre-breakdown phenomena known as partial discharges (PD) which commonly occur in microvoids, defects or protrusions inside the insulation.To improve the performance of the cable insulation against PD, nanofillers are added into the insulating materials. However, to achieve superior performance of PD resistance, the nanofillers must be homogeneously dispersed into the polymer matrices withtightly bonded interfacial zones. Therefore, this could be achieved by employing method of surface functionalization by using cold atmospheric plasma to strengthen the filler/polymer interfaces. In view of foregoing, this study investigated the effects of surface treated boron nitride (BN) nanoparticles in Low Density Polyethylene (LDPE) on the PD characteristics by following CIGRE Method II at 7 kVrmsapplied voltage. The phase resolved PD characteristics were performed. The results revealed that by treating the nanofillers with cold plasma, the PD resistance of LDPE were highly achieved compared with the untreated BN nanofillers.
EXPERIMENTAL INVESTIGATIONS ON EFFECTIVENESS OF ACOUSTIC MATERIAL AS THERMAL ...ijmech
Sound pollution is big problem now-a-days and it causes many health issues. Soundproofing can be used to mitigate the effect of sound pollution, but it adds to the building cost. However, acoustic materials have low thermal conductivity and they may result in saving due to reduced use of electrical energy for heating/cooling of buildings. In the present work, the effectiveness of a commercially available acoustic material, made of Compressed Wood Fiber Cement Composites with a backing of Anti vibration Pad, as a thermal insulator is experimentally investigated. A CAD model of anti-vibration pad material was developed by scanning it with micro CT, converting grey scale data into binary scale by CTan software and extracting 3D- Model from binary data by using Scan IP software. The CAD model was imported into ANSYS workbench for determining thermal conductivity of the anti-vibration pad, which was experimentally validated. The thermal conductivity of composite material was then calculated by Fourier equation. A comprehensive CAD model of anti-vibration pad, composite material and brick-and-mortar wall was used to simulate the variations in room temperature with ambient temperature for one calendar year. The results show that acoustic insulation material also serves as a thermal insulator keeping the room nearly constant with varying ambient temperature

Performance of high power light emitting diode for various zinc oxide film th...eSAT Journals
Abstract Oxide ceramic materials have attractive features either as filler or substrate materials in electronic packaging. Consequently, ZnO thin film for various thicknesses was prepared over Al substrates by RF sputtering and used as heat sink for high power LED. The thermal transient curve of device under test (DUT) was recorded for five boundary conditions. Rise in junction temperature (TJ) was measured and observed low value (54.4°C) for 200 nm ZnO thin films at 350 mA. The difference in junction temperature rise (ΔTJ) was observed as 7.46 °C at 700 mA when compared to bare Al substrates. The total thermal resistance (Rth-tot) of the DUT was low for 200 nm ZnO thin film coated Al substrates. AFM images were used to evaluate the surface roughness factors and their influence on thermal resistance. As expected, the surface roughness, grain size and peak-valley distance were strongly influenced the heat flow. Index Terms: ZnO thin film, thermal interface material, LED, thermal resistance, surface roughness
IRJET- Experimental Study on Strength of Concrete Containing Waste Materials ...IRJET Journal
This document presents the results of an experimental study on the strength of concrete containing waste materials like brick kiln dust and sawdust, as well as nano silica. Concrete cubes were made by partially replacing fine aggregate with these wastes and cement with nano silica. Testing showed that replacing 25% of fine aggregate with brick kiln dust and 10% with sawdust increased compressive strength compared to normal concrete. Compressive strength also increased with the addition of 1% nano silica compared to a control sample without nano silica. The study aims to reduce environmental pollution from waste and costs of concrete construction through the use of industrial byproducts.

Solutions for reducing warpage through underfill design and other techniques are proposed.
A Study on Thermal behavior of Nano film as thermal interface layerIJASCSE
Increase in thermal design power and re-duce in manufacturing cost of the processor chip has pushes the need for high performance and durable test fixture design in future. Test fixture with efficient themal management has lowest resistance possible to maintain the accuracy of the device temperature when it makes contact with processor chip’s silicon during test. High thermal conductivity and mechanical relia-bility of text fixures are desired for high volume test environment.

Thermal con-ductivity of the prepared films is tested by using the ASTM 5470 Thermal Interface Material (TIM) Tester. Titanium on Titanium nitride (Ti on TiN) and Alumi-num (III) Oxide (Al2O3) observed with highest thermal conductivity of 117.68 W/mk and 128.34 W/mk respec-tively among the prepared nano thin films. Thickness of the film and stack configuration influenced the thermal conductivity of the prepared film.
Increase In Electrical And Thermal Conductivities Of Doped Polymers Dependent...IOSR Journals
Most Polymers do not possess natural intrinsic properties that will be enough for them to be used as semi- conductors. In the world trend of industrial growth where polymers seem to be replacing all semi-conductors because of their availability, durability, recyclability and reduced cost, attention is being strongly given to their improvement them for this essential function hence the need for this research.Eight samples each of four polymers; polyethylene (PE), polystyrene (PS), poly propylene (PP),nylon 66 were prepared by doping with different concentrationsof graphite to enhance their electrical and thermal conductivities, considering the fact that they are of different intrinsic properties. The samples were testedfor their electrical and thermal conductivities.It was evident that as the concentration of the graphite dopantincreases, the electrical and thermal conductivities of all the polymers increased although not at the same rate.The most interesting fact is that all polymers that showed highly favorable results in electrical conductivity, showed the least for thermal conductivities which can be attributed to their intrinsic properties.

Further microstructural characterization is needed to understand interactions between nano-materials in concrete mixtures.
Character recognition of kannada text in scene images using neuralIAEME Publication
Character recognition in scene images is one of the most fascinating and challenging
areas of pattern recognition with various practical application potentials. It can contribute
immensely to the advancement of an automation process and can improve the interface
between man and machine in many applications. Some practical application potentials of
character recognition system are: reading aid for the blind, traffic guidance systems, tour
guide systems, location aware systems and many more. In this work, a novel method for

method uses zone wise horizontal and vertical profile based features of character images. The
method works in two phases. During training, zone wise vertical and horizontal profile based
features are extracted from training samples and neural network is trained. During testing, the
test image is processed to obtain features and recognized using neural network classifier. The
method has been evaluated on 490 Kannada character images captured from 2 Mega Pixels
cameras on mobile phones at various sizes 240x320, 600x800 and 900x1200, which contains
samples of different sizes, styles and with different degradations, and achieves an average
recognition accuracy of 92%. The system is efficient and insensitive to the variations in size
and font, noise, blur and other degradations.
1) The document discusses why management systems often fail in organizations. It identifies several common root causes of failure, including a lack of strategic adoption of standards to meet organizational needs and gaps, poor knowledge of how to effectively implement management systems, and treating systems as just documentation rather than integrating them into daily operations.
2) Additional causes are listed as not establishing clear, measurable objectives aligned with organizational vision; excluding financial functions from management systems; failing to follow established procedures; and treating management system audits as compliance checks rather than opportunities for improvement.
3) The author argues that for management systems to succeed, organizations must adopt them proactively to address their own needs, integrate systems into all functions and decision making, and
This document presents a new integrated bridgeless PWM power converter for power factor correction. The proposed converter integrates a bridgeless boost rectifier with an asymmetrical pulse-width modulation half-bridge DC-DC converter. This eliminates the need for a full-bridge diode rectifier, reducing conduction losses. Zero-voltage switching of the power switches also reduces switching losses. Experimental results from a 250W prototype show the converter achieves 93.0% efficiency and near unity power factor.

Performance and flow characteristics of floor swirl diffuser under differIAEME Publication
The document describes an experimental study of the performance and flow characteristics of three different floor swirl diffuser models under varying operating conditions. An acrylic room with dimensions of 4ft x 4ft x 5ft was used, containing one of the diffuser models and a 1500W heater as a heat source. Temperature readings were taken at six locations within the room, with and without the heat load, and for the three diffuser models. The 80-degree swirl diffuser model showed the least variation in temperature with height. In general, temperature variation reduced with increasing distance from the heat source. The swirl action from the diffusers helped achieve more uniform temperature distribution and equalization within the room.

Design, fabrication and heat transfer study of green house dryer 2IAEME Publication
This document summarizes a study that designed, fabricated, and tested a greenhouse dryer to dry crops using solar energy. Experiments were conducted to dry bitter melon using both open-air drying and greenhouse drying. Measurements of solar intensity, humidity, temperature, air velocity, and moisture removal rate were recorded over time. The data was used to determine the convective heat transfer coefficient for both drying methods. It was found that the convective heat transfer coefficient was lower for greenhouse drying than open-air drying, especially at the beginning of the drying process. However, greenhouse drying helps prevent moisture loss and allows crops to be dried year-round.

This document reports on an experimental study that investigated the effects of different types and concentrations of cost-effective nanoparticles on the thermal, electrical, and dielectric properties of polypropylene nanocomposites. Dielectric spectroscopy was used to measure the relative permittivity and loss tangent of polypropylene samples with and without nano-fillers at various frequencies and temperatures. The results showed that the addition of clay or fumed silica nanoparticles in concentrations of 1-10% by weight can impact the dielectric behavior and resistivity of the polypropylene composites depending on the nanoparticle type, concentration, and temperature of the nanocomposite.
Measurement of Dielectric Properties of Low-Density Polyethylene Nanocomposit...TELKOMNIKA JOURNAL
This document summarizes a study that measured the dielectric properties of low-density polyethylene (LDPE) nanocomposites filled with hexagonal boron nitride (h-BN) nanofillers using dielectric spectroscopy. Three concentrations of h-BN filler (0 wt%, 5 wt%, and 10 wt%) were investigated. The results showed that the 5 wt% composite had lower dielectric loss and permittivity than the unfilled polymer, likely due to interactions limiting polymer chain movement. Higher filler loading of 10 wt% increased permittivity and loss, due to the filler's higher permittivity influencing the effective permittivity. This study provides insight into how h-BN filler concentration affects the dielectric properties of LDPE

IRJET- Enhancement Performance of Polymer High Voltage Insulators using Nano-...IRJET Journal
The document discusses enhancing the performance of polymer high voltage insulators using nano-fillers. It aims to study the electrical properties of epoxy composites containing inorganic fillers of different sizes and concentrations under contaminated weather conditions. Epoxy composites were prepared with silica fillers in micro and nano sizes at various weight percentages. Flashover voltage tests were conducted on the samples under dry, wet and salty wet conditions. The results show that flashover voltage generally increases with filler content under dry conditions but decreases under wet conditions due to degradation from water. Nano-filled epoxy samples exhibited higher flashover voltages than micro-filled samples under both dry and wet conditions, with an optimal nano-filler content of 5
Clarification of the optimum silica nanofiller amount for electrical treeing ...TELKOMNIKA JOURNAL
This paper aims to clarify the optimum amount of fumed silica (SiO2) nanofiller in resisting the initiation and propagation of electrical treeing in silicone rubber (SiR). Unlike other works, SiR/SiO2 nanocomposites containing seven different weight percentages of SiO2 nanofiller were prepared for this purpose. To achieve the objective, the electrical tree characteristics of the SiR/SiO2 nanocomposites were investigated by comparing the tree initiation voltage, tree breakdown time, tree propagation length and tree growth rate with its equivalent unfilled SiR. Moreover, the structural and morphological analyses were conducted on the SiR/SiO2 nanocomposite samples. The results showed that the SiR, when added with an appropriate amount of SiO2 nanofiller, could result in an improved electrical tree resistance. It implies that the 5 wt% of silica is the optimum amount to achieve the optimal electrical tree resistance such that above 5 wt%, the tree resistance performance has been abruptly reduced, subjected to the agglomeration issue.
COMPARISON OF DUAL SOURCE TFET USING DIFFERENT DIELECTRIC MATERIALSIRJET Journal
This document compares the performance of a dual source tunnel field-effect transistor (TFET) using different dielectric materials, including hafnium dioxide (HfO2), silicon dioxide (SiO2), and silicon nitride (Si3N4). It analyzes the structure, operation, and simulation results of each TFET design. The key findings are that HfO2, with its higher dielectric constant, provides better performance than SiO2 and Si3N4 by increasing the on current and decreasing the off current, leading to an improved on/off current ratio. Using high-k dielectric materials like HfO2 in TFETs can enable lower power consumption and increased thermal stability.

AN EXPERIMENTAL STUDY ON CONCRETE CONTAINING META KAOLIN WITH HD PET THERMOPL...IRJET Journal
This document presents an experimental study on concrete containing metakaolin and HD PET thermoplastic. Metakaolin was used as a partial cement replacement at 5% and 10%, while HD PET thermoplastic partially replaced fine aggregate at 5-15%. Compressive strength was tested at 7 and 28 days. Results showed that strength generally increased with 5% metakaolin but decreased with higher HD PET contents. However, combinations of 15% HD PET with 5% metakaolin and 15% HD PET with 10% metakaolin achieved strengths similar to the control mix. Therefore, metakaolin and HD PET thermoplastic can be used together in concrete as partial replacements to improve sustainability without compromising strength.

This document describes a study that prepared multilayer titanium dioxide thin films on glass substrates using a sol-gel spin coating method. The films were annealed at temperatures ranging from 50°C to 200°C. The effects of annealing temperature on the structural, morphological, optical, and electrical properties of the films were then characterized through techniques like XRD, Raman spectroscopy, FT-IR, SEM, and four-point probe measurements. The results showed that increasing the annealing temperature improved crystallinity, decreased resistivity, and affected properties like band gap and surface morphology in ways that could impact device applications.

Experimental results showed that composites with 3 wt% MMT loading exhibited maximum density but decreasing tensile strength with increasing MMT content. Fourier transform infrared spectroscopy, thermogravimetric analysis, and differential thermal analysis were used to characterize the composites and observe the thermal behavior and degradation temperatures. Density was found to increase while void content decreased with additions of MMT nanoparticles up to an optimal loading amount.
Effect of silica nanofiller in cross-linked polyethylene as electrical tree ...IJECEIAES
One of the main phenomena that contributes to the non-success of cable insulation made of cross-linked polyethylene (XLPE) is electrical treeing. To improve the XPLE cable insulation, the use of nanofiller has been introduced. Adding the nanofiller in the based composite offers better cable lifetime and resistance to deal with the cable failure. One of the potential nanofillers that can increase the insulation performance of XLPE cable is silica nanofiller. To this extent, the studies on silica nanofiller in XLPE are focusing on the impulse breakdown strength, dielectric loss, permittivity, space charge, alternating current (AC), and partial discharge. The studies reveal that the dielectric properties of the XLPE nanocomposite have significant improvement. Therefore, this work investigates the effect of various concentrations of silica nanofiller in XLPE composite as electrical tree inhibitor. The concentrations of silica nanofiller in XLPE were 0.25 wt%, 0.5 wt%, 0.75 wt%, 1.0 wt%, 1.25 wt%, 1.5 wt%, and 1.75 wt%. The silica nanofillers have 96%-99% purity, 20-30 nm sizes and the shapes are spherical. As a result, the XLPE composite containing 1.5 wt% silica nanofiller demonstrate higher tree inception voltage and detaining the tree propagation speed, which could be considered as an inhibitor medium of electrical tree growth.
This 3-page document provides an overview of green energy harvesting via thermoelectric devices. It discusses how thermoelectric generators directly convert waste heat into electricity without batteries or grid connection. Approximately two-thirds of primary energy produced worldwide is lost as waste heat, representing a potential source for reduced fossil fuel consumption. Thermoelectric devices offer a sustainable power supply with no moving parts and can capture otherwise lost heat. However, their efficiency depends on the thermoelectric material's figure of merit which is challenging to optimize. Currently, telluride materials perform well but rely on scarce resources. Alternative materials like tetrahedrites made of more abundant elements show potential as high-performing and sustainable thermoelectric materials.

STUDY OF ABSORPTION IN CARBON NANOTUBE COMPOSITES FROM 1HZ TO 40GHZjmicro
This document summarizes a study on the absorption properties of carbon nanotube composites from 1Hz to 40GHz. The absorption performances of high density polyethylene and polycarbonate polymer matrices containing various loads of carbon nanotubes were analyzed. Significant absorption between 60-90% was achieved at particular combinations of electrical conductivity, dielectric constant, and thickness in the 1Hz to GHz frequency range. The absorption depended on the quality of carbon nanotube dispersion and increased with higher nanotube loading. Both the electrical conductivity and dielectric constant increased with nanotube concentration, leading to higher absorption as more of the electromagnetic wave was absorbed rather than reflected or transmitted.

The document discusses polymer-based nanodielectric composites for applications requiring high energy density and high temperature dielectric materials. It describes how nanodielectric composites aim to leverage the high breakdown strength of polymers and high permittivity of ceramic fillers. The challenges of maintaining breakdown strength in multi-phase systems are discussed. Well-dispersed, low defect fillers and good particle-polymer interfaces are needed to prevent localized breakdowns. High-K ceramic or ferroelectric fillers could increase permittivity but require optimization to avoid decreasing breakdown strength.

Extensive efforts have been made to harvest energy f from water in the form of raindrops, river and ocean wave, tidal and others. However, achieving a high-density of electrical power generation is challenging. Traditional hydraulic power generation mainly uses electromagnetic generators that are heavy, bulky, and become inefficient with water supply. Alternative, the water droplet or solid-based electric nano-generator, has so far generated peak power densities for less than one watt per square meter, owing to the limit at ions imposed by interfacial effects as seen in characterization of the charge generation and transfer that occur at solid-liquid or liquid-solid interfaces. Here we develop a device to harvest energy from impinging water droplet s by using an architecture that compromises a polytetrafluoroethylene film on an indium oxide substrate plus an aluminium electrode. We show that spreading of an impinged water droplet on the device bridges, the originally disconnect ed component s into a closed-loop electrical system, transforming the conventional interfacial effect into bulk effect, and so enhancing device that is limited by interfacial effects.

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.
