The main purpose of this paper was to investigate an experimental and theoretical analysis of
heat and moisture transport behavior in wood during convective drying process. A convective drying
cell was used to follow the measurements of the water content of samples subject to hot air flow in
longitudinal and transverse moisture transfer of wood. The effects of drying conditions such as
drying air temperature, air velocity and ambient relative humidity on the drying characteristics of
wood has been investigated. The constants drying and diffusion coefficients of the drying model,
which control the drying rate of wood, were determined from fitting the model against the
experimental drying curves. Results showed that, drying kinetic behaviour of the longitudinal
diffusion is very significant than the transverse one. The moisture content increased with increase in
drying air temperature and air velocity but decreased with time. From the curves of moisture flow
evolution versus moisture ratio, convective heat and mass transfer coefficients have been evaluated
and compared with values obtained from the literature and existing correlations.
Effective Moisture Diffusivity and Activation Energy of Tomato in Thin Layer ...drboon
The aim of this paper is to report tomato slice moisture diffusivity data determined and activation energy from experimental drying kinetics. The thin-layer drying experiments were carried out under five air temperatures of 40, 50, 60, 70 and 80ºC, two air velocity 1.5, and 2 m/s and three level of relative humidity 20, 40 and 60%. It was observed that drying took place in the falling rate period. Moisture transfer from tomato slice was described by applying the Fick’s diffusion model. The effective diffusivity values changed from 9.9119×10^-10 to 6.4037×10^-9 m^2/s for the range of temperatures considered. An Arrhenius relation with an activation energy value of 33.3299 to 43.2287 kJ/mol and the diffusivity constant value of 1.7695×10^-4 to 3.09156×10^-2 m^2/s were obtained which shows the effect of drying air temperature, air velocity and relative humidity on the diffusivity.
Using Porous Media to Enhancement of Heat Transfer in Heat ExchangersIJAEMSJORNAL
This document summarizes recent research on using porous media to enhance heat transfer in heat exchangers. Porous media can improve heat transfer by increasing the contact surface area between the fluid and solid matrix, modifying fluid flow patterns, and increasing thermal conductivity. Studies have shown that porous media can both increase heat transfer rates through mechanisms like redistributing flow and enhancing thermal conduction, while also increasing pressure drop. The optimal design of porous media in heat exchangers must balance higher heat transfer with increased pumping requirements.

The low integral finned tube with (19 mm) inner diameter, (21 mm) root diameter and (24 mm) outer diameter. The fin height is (1.5 mm), thickness (1 mm) and the pitch is (2 mm). Air was used as a cooling fluid passing across the test tube with a range of velocities (1, 2, 3 and 4) m/sec.

This document summarizes research on modeling the thermal kinetics of thin layer drying of Indian gooseberry (aonla) flakes. Experiments were conducted drying aonla flakes at air velocities of 0.48m/s, temperatures ranging from 40-75°C, and relative humidity of 35%. Moisture content was measured periodically to calculate moisture ratios. Various drying models (Newton, Page, Modified Page) were evaluated based on their ability to predict experimental moisture values using statistical measures like RMSE, chi-square, and efficiency. The Modified Page model with an exponent of 1 provided the best fit to experimental data with minimum RMSE and chi-square values and maximum efficiency. Correlations were developed between drying coefficient (k) and shape
This study measured the thermal conductivity and viscosity of TiO2 nanoparticles dispersed in deionized water at concentrations up to 3% volume fraction and temperatures from 13°C to 55°C. Thermal conductivity was measured using the 3ω method, which was validated on pure fluids. Results showed thermal conductivity increased with particle concentration but not anomalously, and was not strongly temperature dependent. Viscosity significantly increased with particle concentration beyond classical models, and decreased exponentially with temperature like the base fluid. Increasing temperature and particle concentration both increased heat transfer properties, with viscosity enhanced more than thermal conductivity.
Effect of pitch on heat transfer characteristics of helical coils to be used ...eSAT Journals
This document discusses a study on the effect of pitch variation on heat transfer characteristics of helical coils used for biogas production. Three helical coil models with the same dimensions but different pitches (75mm, 50mm, 25mm) were modeled and analyzed using computational fluid dynamics (CFD). The results showed that increasing pitch enhanced heat transfer but also increased pressure drop. Maintaining an optimal reactor temperature through efficient heat transfer from helical coils can improve biogas production.
This document discusses numerical simulations of heat transfer in an annulus tube with internal fins. The simulations solve the governing equations for mass, momentum, energy and turbulence using a k-ε model. Various fin configurations are analyzed by varying the number, shape and size of fins. The results show that heat transfer increases with fin number and height. Trapezoidal fins have higher heat transfer than other shapes. The study aims to determine the optimal fin design for maximum thermal performance in the annulus tube.
The objective of the study is to find a relation for the predicting convective and evaporative
heat transfer coefficient and distillate output for 200 mm and 160 mm water depth. In this present
work an attempt is to be made to use inner glass cover temperature instead of outer glass temperature
as done by other researchers. The sides of the wall of the condensing cover are made up of FRP sheet
to avoid heat losses from sides and to provide the desired inclination to the cover to the bath. It is
exposed to room condition to increase the difference between water temperature and the condensing
cover temperature to increase the heat transfer rate and thus the condensate output.
The operating temperature range for the experiment is to be maintained at steady state from
50oC to 90oC by using a constant temperature bath. The yield obtained for a 1/2 hour intervals were
used to determine the values of constant C and n and consequently convective and evaporative heat
transfer coefficient. It is therefore expected that higher yield is to be obtained at higher temperature
and at minimum depth of water

Experimental Investigation of a Dimpled Plate by Natural Convection Heat Tran...IRJET Journal
This document summarizes previous research on using dimpled surfaces to enhance heat transfer via natural convection. It begins by defining natural convection and explaining how dimpled surfaces promote turbulence and vortex formation, augmenting heat transfer. The document then reviews several studies that experimentally investigated heat transfer over dimpled plates and tubes. Most found that heat transfer increased with dimple density, depth, and Reynolds number. The objectives of the proposed new study are to analyze heat transfer from vertically heated dimpled plates with variations in dimple shape, size, and arrangement. It is hypothesized that dimpled plates will enhance thermal performance over smooth plates through increased surface area and reduced flow separation.

FLUID FLOW ANALYSIS IN AIR DUCT FLOW WITH AND WITHOUT INTERNAL THREADS USING ...IAEME Publication
Computational heat transfer flow modeling is one of the great challenges in the classical sciences. As with most problems in engineering, the interest in the heat transfer augmentation is increasing due to its extreme importance in various industrial applications. This paper deals with the analysis of heat transfer for fluid flowing through the pipe with and without internal threads using CFD. Using CFD codes for modeling the heat and fluid flow is an efficient tool for predicting equipment performance. CFD offers a convenient means to study the detailed flows and heat exchange processes, which take place inside the tube. Simulations were carried out using commercial CFD software ANSYS Fluent version 14.5. Friction factor and Nusselt number for air flowing through the specified tube (internal diameter = 0.005 m, length = 0.1 m) were obtained first for the plain tube and then for the tube with internal threads with pitch 5mm in the Reynolds number range of 2000 to 5000. Finally results will be compared to available experimental and analytical calculations. The data obtained by simulation are matching with the literature value for a plain tube with the discrepancy of less than plus or minus 5% for Nusselt number and for the friction factor.
Enhanced heat transfer for the tube with internal threads has been observed. Heat flux is more uniform all along the tube and decreases uniformly towards the center.

Experimental analysis of heat transfer enhancementin circulariaemedu
This document summarizes an experimental study on enhancing heat transfer in a circular double tube heat exchanger using rectangular inserts. Air was passed through the inner tube while hot water flowed through the outer tube. Heat transfer coefficients and friction factors were determined for the plain tube and with inserts. The results showed that heat transfer was enhanced by 0.9 to 1.9 times with the inserts due to flow disruption, while friction factors increased by 1 to 1.7 times. Heat transfer coefficients increased with Reynolds number whereas friction factors decreased. Validation experiments on a plain tube agreed well with theoretical predictions within 10% uncertainty.
Applications of quartering method in soils and foodsIJERA Editor
Sampling is a technique and a science. If the appropriate technique is followed it reduces the bulk mass and helps to respect the batch composition as best as possible. Non-representative sampling results in incorrect analysis. Soils and foods are materials constantly assessed. Subsampling methods, as conning and quartering are applied in solid samples. Then they could be functional in soils, and granular foods, like grains, cereals or nuts. The method is very dependent on the skill of the operator then great care must be taken when obtaining a sample by coning and quartering. It has some advantages, like the easiness, cleanness and inexpensiveness. But it is usually inaccurate and can provide non-representative samples.

CFD Analysis to Analyze Thermal Characteristics of a Heat Exchanger Handling ...ijtsrd
It takes a lot of energy to have a good life. For living and working, humans nowadays rely on an abundant and constant source of power. Because energy is depleting at such a rapid rate, it has become important to use heat more efficiently, which necessitates that we preserve. As a result of the global energy crisis, many researchers have worked to improve the efficiency of thermal systems and reduce the size and thus energy consumption rates, which is one of the most critical problems due to the large and continuing increase in consumption, the increasing scarcity of energy resources, and the high cost. A 3 dimensional numerical 3 D simulation was used to evaluate the thermal properties of a heat exchanger managing a combination of dimple ribs. Handling air flow velocity through the channel was varied from 3.97 to 5.80 m s. is the subject of this study. The heat transfer physiognomies of a heat exchanger managing a combination of dimple ribs were studied using the simulation tool ANSYS 19.2. The numerical results showed that the combination of dimple ribs enhanced heat transfer significantly more than the dimple. In comparison, the average Nusselt number of a combination of dimple ribs is 4.28 percent higher than that of a channel with dimpled Plate.

Two different weight fractions (0.1% and 0.5%) of TiO2 nanofluids were prepared and their heat transfer performance was experimentally tested in the plate heat exchanger. The results showed that the 0.5% nanofluid provided significant enhancement of the overall heat transfer coefficient at higher Reynolds numbers compared to water, while the 0.1% nanofluid showed a decrease compared to water.
Analytical and Experimental analysis ofthermal characteristics throughTriangu...IJERA Editor
Microscale heat transfer technique is widely intended for best cooling applications in electronic devices as high
heat transfer coefficients are achieved in microscale convection. In present study, analysis of thermal
characteristics has been carried out by analytical calculations along with experimental investigation for a straight
microchannel heat sink of equilateral triangular cross section of 173.21 μm hydraulic diameter with distilled
water as the working fluid. Designed Heater input watts and Reynolds number based on flow rate are varied for
optimized microchannel geometry. Experimental analysis is carried out under constant heat flux condition. The
microchannels are produced on highly accurate micro wire cut EDM. The Reynolds number is varied from 100
to 700. The major intension for this work is to enhance heat transfer coefficient and minimize pressure drop
across microchannel. The Reynolds number, temperature distribution, pressure distribution, heat transfer
coefficient, hydrodynamic entrance length, thermal entrance length, equivalent thermal resistances parameters
are calculated for microchannel heat sink performance analysis. The results of analytical calculations are verified
with experimental investigation. It is found that heat transfer coefficient and pressure drop increases with
increase in Reynolds numbers and decrease in microchannel heat sink hydraulic diameter. Also channel length is
directly proportional to temperature rise

Non-representative sampling results in incorrect analysis. Soils and foods are materials constantly assessed. Subsampling methods, as conning and quartering are applied in solid samples. Then they could be functional in soils, and granular foods, like grains, cereals or nuts. The method is very dependent on the skill of the operator then great care must be taken when obtaining a sample by coning and quartering. It has some advantages, like the easiness, cleanness and inexpensiveness. But it is usually inaccurate and can provide non-representative samples.

A Review on Comparative Study of Thermal Performance of Artificially Roughene...IRJAES
This document reviews research on enhancing heat transfer in solar air heaters through the use of artificial surface roughness. It summarizes findings from several studies that have experimentally analyzed heat transfer performance for different roughness configurations and geometries. The highest average Nusselt numbers were found for a multi V-rib roughness configuration experimentally, while analytical models predicted higher values for end-of-side roughened collectors. A roughness Reynolds number of around 24 was found to give optimal thermal-hydraulic performance across a range of studies.

CFD Analysis to Analyze Thermal Characteristics of a Heat Exchanger Handling ...ijtsrd
It takes a lot of energy to have a good life. For living and working, humans nowadays rely on an abundant and constant source of power. Because energy is depleting at such a rapid rate, it has become important to use heat more efficiently, which necessitates that we preserve. As a result of the global energy crisis, many researchers have worked to improve the efficiency of thermal systems and reduce the size and thus energy consumption rates, which is one of the most critical problems due to the large and continuing increase in consumption, the increasing scarcity of energy resources, and the high cost. A 3 dimensional numerical 3 D simulation was used to evaluate the thermal properties of a heat exchanger managing a combination of dimple ribs. Handling air flow velocity through the channel was varied from 3.97 to 5.80 m s. is the subject of this study. The heat transfer physiognomies of a heat exchanger managing a combination of dimple ribs were studied using the simulation tool ANSYS 19.2. The numerical results showed that the combination of dimple ribs enhanced heat transfer significantly more than the dimple. In comparison, the average Nusselt number of a combination of dimple ribs is 4.28 percent higher than that of a channel with dimpled Plate.

Microscale heat transfer technique is widely intended for best cooling applications in electronic devices as high
heat transfer coefficients are achieved in microscale convection. In present study, analysis of thermal
characteristics has been carried out by analytical calculations along with experimental investigation for a straight
microchannel heat sink of equilateral triangular cross section of 173.21 μm hydraulic diameter with distilled
water as the working fluid. Designed Heater input watts and Reynolds number based on flow rate are varied for
optimized microchannel geometry. Experimental analysis is carried out under constant heat flux condition. The
microchannels are produced on highly accurate micro wire cut EDM. The Reynolds number is varied from 100
to 700. The major intension for this work is to enhance heat transfer coefficient and minimize pressure drop
across microchannel. The Reynolds number, temperature distribution, pressure distribution, heat transfer
coefficient, hydrodynamic entrance length, thermal entrance length, equivalent thermal resistances parameters
are calculated for microchannel heat sink performance analysis. The results of analytical calculations are verified
with experimental investigation. It is found that heat transfer coefficient and pressure drop increases with
increase in Reynolds numbers and decrease in microchannel heat sink hydraulic diameter. Also channel length is
directly proportional to temperature rise

The aim of this study is to investigate a technique to enhance the air swirl to achieve
betterment in engine performance characteristics in a direct injection (DI) single cylinder diesel
engine. A good swirl promotes the fast combustion and improves the efficiency. The engine should
run at low speeds in order to have low mechanical losses and fast combustion, enabling good
combustion efficiency. Therefore to produce high turbulence prior to combustion within the cylinder,
swirl induced by the inlet manifold will be helpful. This paper aims at studying the effect of air swirl
generated by directing the air flow in intake manifold on engine performance. The turbulence is
achieved in the inlet manifold with different types of internal threads of constant pitch. In view this,
experimental investigation has been carried out to find the effect of swirl on the performance
characteristics of the engine, by inducing swirl in inlet manifolds with three different types of
internal threads viz. acme, buttress and knuckle threads of constant pitch. The results indicate that
inlet manifold with buttress threads is identified as optimum configuration based on performance
characteristics of engine. This is because inlet manifold with buttress threads achieved a higher swirl
coefficient and swirl ratio compared with inlet manifold having acme and knuckle threads

The thin layer drying behavior of Psidium guajava L (guava fruit) cultivar Rayalaseema area AP,
India, were studied experimentally to examine the influence of drying air temperature, slice thickness, and air
velocity on the drying curves. Drying operation was carried out at 55oC, 60oC and 65oC temperatures, at slice
thickness of 2.5 mm, 4 mm and 6 mm at 1 and 1.5 m/sec velocities. The predominant falling rate drying regime
was observed. The analysis reveals that, the drying temperature and slice thickness has a significant effect and
velocity has a least effect on moisture removal. Drying rate is found to increase with the increase in air
temperature and thus reduced the drying time. Drying time increases with increase in slice thickness. The
various drying models in defining the suitability of drying behavior were examined by statistical analysis. The
analysis reveals, that the Henderson and Pabis model is better model that explains the drying behavior of
Guava Fruit (R2=0.993).

An experimental study of forced convection green house dry 2IAEME Publication
This document summarizes an experimental study on forced convection greenhouse drying. Experiments were conducted to design, fabricate, and test the performance of a greenhouse dryer operating in forced convection mode. Measurements of variables like solar intensity, humidity, temperature, and moisture removal rate were recorded for bitter melon samples undergoing drying in the greenhouse dryer and via open sun drying. The average convective heat transfer coefficient was found to be higher for forced convection greenhouse drying compared to open sun drying. A thermal model was developed and constants in the Nusselt number expression were determined for both drying methods. The maximum convective heat transfer coefficient and average drying rate were higher for forced convection greenhouse drying.
Porous media has two specifications: First its dissipation area is greater than the conventional fins that enhance heat convection. Second the irregular motion of the fluid flow around the individual beads mixes the fluid more effectively. Nanofluids are mixtures of base fluid with a very small amount of nanoparticles having dimensions from 1 to 100 nm, with very high thermal conductivities, so it would be the best convection heat transfer by using porous media and nanofluids. Thus studies need to be conducted involving nanofluids in porous media. For that, the purpose of this article is to summarize the published subjects respect to the enhancement of convective heat transfer using porous media and nanofluids and identifies opportunities for future research.
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 work is designed to carry out the statistical modelling of the drying characteristics of unripe plantain (Musa paradisiaca) slices and to study the effect of drying temperature and slice thickness on drying characteristics. The test samples were dried in a laboratory scale oven dryer at varying temperatures of 700C, 800C and 900C, and different slice thicknesses of 2mm, 3mm and 4mm.The result obtained indicated that drying temperature and slice thickness had significant effect on drying rate and hence moisture profile. The moisture ratio – drying time data obtained were fitted to ten thin layer drying models. The fit quality obtained with each model was evaluated using statistical tests namely; coefficient of determination (R2), root mean square error (RMSE), reduced chi-square (X2), and standard error of estimate (SEE). Although most of the models fitted quite well to the experimental data, Page and Modified Page models showed the highest average R2 and the lowest average RMSE, X2 and SEE values. Page and modified Page models were selected and found suitable to represent the drying characteristics of unripe plantain slices and predict drying times.
This study evaluated the effects of ultrasound pretreatment on osmotic dehydration of mango cubes. Mangoes were cut into cubes and some samples received ultrasound pretreatment before being subjected to osmotic dehydration in a 45° Brix sucrose solution at 65°C. Samples were analyzed for water loss, solid gain, and effective diffusion coefficients over time. Results showed that ultrasound pretreatment increased water loss, solid gain, and the effective diffusivity of water and solids compared to samples without pretreatment. Modulated temperature differential scanning calorimetry was also used to characterize changes in the food matrix, such as increases in glass transition temperature, with decreasing moisture content.
Thesis Publication_Journal of Fuel Processing Technology2016Ibrahim Ogunfayo
This research article studied how the mechanical properties of three types of wood pellets (white wood, torrefied, and steam-exploded) changed when exposed to different relative humidity (RH) and temperature conditions in a laboratory environment. The three pellet types were exposed to either high RH (90%) at ambient and elevated temperatures, or low RH (10%) at varying temperatures. Exposure to high RH and elevated temperatures caused a substantial decrease in the shear modulus of all three pellet types, with decreases ranging from 50% to 92% after 4 days. The steam-exploded pellets saw the lowest decrease in mechanical durability but the largest decrease in shear modulus. Storage at low RH did not cause observable degradation

Numerical Simulation of Solar Greenhouse Dryer Using Computational Fluid Dyna...RSIS International
Moisture removal from crops and other food items is
one of the ways to preserve them for longer duration. Previously,
drying openly in sun was used to reduce moisture content. But it
had some disadvantages like contamination due to dirt and other
unwanted elements as well as attack by rodents and birds.
Drying in covered close space with vents would be helpful in
overcoming these problems. Solar greenhouse dryers are the
close conduits in which crops can be dried without negatively
affecting the nutrition value. The factors affecting the crop
drying are solar radiation, climatic conditions, material of which
the dryer is made of and shape of the dryer. A lot of
experimental investigations have been done to improve the
drying rate. With the advances in computational power and
numerical techniques, Computational Fluid Dynamics (CFD) has
emerged as a powerful tool to optimize any design. In the present
study, simulations have been done on greenhouse dryer with
modifications to identify the temperature distribution with
variation in wind velocity. Different radiation levels have also
been found out at different locations in the dryer. The model of
the dryer has been created in CREO 5.0 and analysis has been
performed using ANSYS 14.0. The simulation has been done for
both forced and natural convection. Obtained results have been
validated with the experimental work done by previous works.
Better drying rate has been obtained for forced circulation as
compared to natural convection which is in agreement with the
available experimental results.

The objective of the study is to find a relation for the predicting convective and evaporative heat transfer coefficient and distillate output for 200 mm and 160 mm water depth. In this present work an attempt is to be made to use inner glass cover temperature instead of outer glass temperature
as done by other researchers. The sides of the wall of the condensing cover are made up of FRP sheet to avoid heat losses from sides and to provide the desired inclination to the cover to the bath. It is exposed to room condition to increase the difference between water temperature and the condensing
cover temperature to increase the heat transfer rate and thus the condensate output.
This study examined the effect of fabric softener on the thermal comfort properties of cotton and polyester fabrics after repeated laundering. It found that fabric softener treatment significantly decreased the air permeability and wickability of cotton fabrics but did not affect polyester fabrics. The softener treatment increased the thermal insulation value of both cotton and polyester fabrics to a similar degree. Statistical analysis showed the results were significant for air permeability, thermal insulation value, and wickability of the fabrics. The chemical finishing had a significant influence on the thermal comfort properties of cotton and polyester fabrics after repeated laundering cycles.

BROAD UNEXPOSED SKILLS OF TRANSGENDER ENTREPRENEURSIAEME Publication
Since ages gender difference is always a debatable theme whether caused by nature, evolution or environment. The birth of a transgender is dreadful not only for the child but also for their parents. The pain of living in the wrong physique and treated as second class victimized citizen is outrageous and fully harboured with vicious baseless negative scruples. For so long, social exclusion had perpetuated inequality and deprivation experiencing ingrained malign stigma and besieged victims of crime or violence across their life spans. They are pushed into the murky way of life with a source of eternal disgust, bereft sexual potency and perennial fear. Although they are highly visible but very little is known about them. The common public needs to comprehend the ravaged arrogance on these insensitive souls and assist in integrating them into the mainstream by offering equal opportunity, treat with humanity and respect their dignity. Entrepreneurship in the current age is endorsing the gender fairness movement. Unstable careers and economic inadequacy had inclined one of the gender variant people called Transgender to become entrepreneurs. These tiny budding entrepreneurs resulted in economic transition by means of employment, free from the clutches of stereotype jobs, raised standard of living and handful of financial empowerment. Besides all these inhibitions, they were able to witness a platform for skill set development that ignited them to enter into entrepreneurial domain. This paper epitomizes skill sets involved in trans-entrepreneurs of Thoothukudi Municipal Corporation of Tamil Nadu State and is a groundbreaking determination to sightsee various skills incorporated and the impact on entrepreneurship.

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.

Webinar: Designing a schema for a Data WarehouseFederico Razzoli
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

DLAU und die Lizenzen nach dem CCB- und CCX-Modell sind für viele in der HCL-Community seit letztem Jahr ein heißes Thema. Als Notes- oder Domino-Kunde haben Sie vielleicht mit unerwartet hohen Benutzerzahlen und Lizenzgebühren zu kämpfen. Sie fragen sich vielleicht, wie diese neue Art der Lizenzierung funktioniert und welchen Nutzen sie Ihnen bringt. Vor allem wollen Sie sicherlich Ihr Budget einhalten und Kosten sparen, wo immer möglich. Das verstehen wir und wir möchten Ihnen dabei helfen!
Wir erklären Ihnen, wie Sie häufige Konfigurationsprobleme lösen können, die dazu führen können, dass mehr Benutzer gezählt werden als nötig, und wie Sie überflüssige oder ungenutzte Konten identifizieren und entfernen können, um Geld zu sparen. Es gibt auch einige Ansätze, die zu unnötigen Ausgaben führen können, z. B. wenn ein Personendokument anstelle eines Mail-Ins für geteilte Mailboxen verwendet wird. Wir zeigen Ihnen solche Fälle und deren Lösungen. Und natürlich erklären wir Ihnen das neue Lizenzmodell.
Nehmen Sie an diesem Webinar teil, bei dem HCL-Ambassador Marc Thomas und Gastredner Franz Walder Ihnen diese neue Welt näherbringen. Es vermittelt Ihnen die Tools und das Know-how, um den Überblick zu bewahren. Sie werden in der Lage sein, Ihre Kosten durch eine optimierte Domino-Konfiguration zu reduzieren und auch in Zukunft gering zu halten.
