These nodes may vary between hundreds to thousands depending on the size and nature of data (signals) to be detected. Wireless sensor networks are expected to operate over long periods without being attended to. The range of this period may span from some months to even years. However, due to its resource constraints i.e. limited battery power, low bandwidth, limited sensing range and low memory. It is pertinent that its resources must be optimally utilized. This paper addresses a secured routing protocol to a specified sink in a multi-sink scenario. It is a subset of a novel algorithm required to securely route to multiple mobile sinks in WSN. It employs reinforcement learni...

The process optimization was done with respect to the flow rates (L h−1) and residence time (τ) of wastewater which resulted in the excellent removal of Total solids (TS), colour and Chemical Oxygen Demand (COD). The removal rate of COD was 94.4 and 93.1% at the optimal flow rates of 0.5 and 1.0 dm3 h−1, correspondingly, whereas the colour removal rate was 91.6 and 83.6%. There was gradual decrease in the pH of the effluent during the process due to the production of aluminium hydroxides in variable oxidation states. Variation in the cell voltage during the electrolysis has also been studied. TDS of effluent was also decreased by a factor of 93% after 4 h residence time at a flow rate of 0.5 dm3 h−1. With a variation in flow rates, electrode degradation and consumption were also examined.

To overcome this problem, we are moving towards vertical constriction. The main problem in moving towards vertical construction is the foundation system, if the foundation system in high rise buildings is not planned and designed smartly and economically then there are different problems related to the foundation system that is going to arise, the soil in that area also plays a very important role in designing of the economical and stable foundation system. It is always beneficial to have a raft foundation on alluvial soil for high-rise buildings. But, however, it is a matter of great concern what foundation will be proposed on such types of natural soils or man-made refills. In this paper, an attempt has been made to design a raft foundation based on its geotechnical analysis. An extensive survey of research works devoted to studying the geotechnical parameters affecting the behav-ior of raft foundations is carried out with detailed experiments raft foundations are increasingly being recognized as an economical and effective foundation system for high-rise buildings. This paper sets out some principles of design for such foundations, including design for the geotechnical ultimate limit state, the structural ultimate limit state, and the serviceability limit state. Attention will be focused on the improvement in the foundation performance due to the raft being in contact with, and embedded within, the soil.

Water as a commodity is very scarce and follows a downward trend with every passing day. The Middle East and North Africa region accommodates almost 5% of the world's population but contain less than 1% of the world's annual renewable freshwater. The cities are growing at a rate of 4% every year, so this is only going to worsen the demand and supply of water. Hence the use of algae (microalgae and marine macroalgae, commonly known as seaweeds) particularly microalgae can help treat the water efficiently and cater to the demand of the growing population. The omnipotent stature of algae and their adaptation to multifarious habitats makes them tolerant to a wide range of environmental conditions, including nutrient levels. The algae can work as a carbonreducing system that can convert carbon dioxide into oxygen through photosynthesis, due to its handling of adverse conditions we can use microalgae for bioremediation of wastewater and the biomass produced during the process can serve as food, fertilizers, and late, biofuels.

So, the use of excessive aggregate may lead to higher prices as a requirement of natural resources being costly. Solid waste management is attracting considerable interest these days. Different types of solid waste, such as waste tyres, have become a source of concern because they are not biodegradable in nature. In many industries, for instance, thermal power plants. The large proportion of discarded tyre rubber is converted into fuels, Cement furnaces, brick furnaces etc. Sadly, such use is not environmentally friendly and highly demanding, but it is costly. As a result, the use of such leftover tyre rubber in making concrete was deemed to be an additional method of waste disposal. This type of garbage is intended to safeguard the environment. Attempts made in this analysis to classify the different properties are mandatory for the creation of concrete mix with rough tyre rubber particles to be used as aggregate in a systematic manner. As part of this project, the M20 grade concrete was selected as the reference concrete specimen. In place of traditional coarse aggregate, rubber tyre granules in the form of cementitious material are employed.

As per surveys, most parts of these pumps have validation from the experience of designers as a result of which there isn't any mathematical tool for design optimization of different parts. Although there are now companies e.g. Oilgear Towler, who are in favor of, and themselves inserted, slots (grooves) on the slippers and in pistons as we shall in this report, there is no particular study to realize their benefits and drawbacks. Therefore, it is necessary to study the advantages and disadvantages arising due to the presence of grooves on the surface of different parts of the pump mathematically or through CFD solvers. In this project work, the aim is to analyze the effect of design parameters and working conditions on the pump behavior. This is done using a parametric study performed on a model of the slipper and simulating the physical problem on ANSYS. As major leakage occurs between slipper and swash plate clearance therefore in this project report static and dynamic analysis of slipper is done. The Navier Stokes Equations are solved in 3-D to acquire results using Rhie and chow method and ANSYS FLUENT solver. The various design points which affect the efficiencies of a pump in a positive manner, if any, shall be discussed in the conclusion part.

Technology has undergone significant modifications, resulting in an increase in speed. However, high speed contributes to traffic accidents. When the driver is not attentive, ordinary braking is insufficient to prevent accidents. The braking system must be improved further in order to brake a vehicle when the driver is unable to do so, which may necessitate the use of an automatic braking system. The vehicle may brake without the driver's assistance using this autonomous braking technology. An automated braking system is an important aspect of car safety technology. It's a sophisticated system that's designed to avoid colliding with another vehicle or an obstacle of some sort. These systems use sensors like radar, video, infrared, and ultrasonic to scan for potential obstacles in front of the car and then use brake control to avoid a collision if the object is found.

Concrete was created as a stronger and more resistant building material as it was worked upon over time. Gradually, the man figured out how to create it, transport it, and utilize it more efficiently. We know that concrete is made from cement, sand, aggregate, and water. Out of these, some of them may be replaced with some other material like wheat straw ash, rice husk ash, fly ash, etc. for various purposes, mostly to utilize waste material without affecting the important properties of concrete beyond acceptable limits. This study deals with an investigation into the properties of concrete by partial replacement of sand with wheat straw ash and the addition of polypropylene fiber in it. Wheat Straw is the portion of leftovers of the wheat crop after it is harvested. In most countries, it is a waste. People burn it and cause pollution and health hazards, good strength and high performance in concrete are very much required in future construction work. It is felt that fiber dispersion in concrete is one method to improve the structural characteristics of concrete.

With the help of ANSYS fluent, two designs are considered to investigate the effect of different rib heights (e = 1, 1.2, 1.4, 1.6, and 1.8) and duct depths (h = 16, 18, 20, 22, and 24). The effects of different parameters such as velocity, temperature, turbulence kinetic energy, and turbulence energy are compared to optimize the performance of designs 2 and 3. It is noticed that except temperature, all other parameters are on the lower side for design 2 as compared to design 3, due to improper air mixing in design 2. The authors presented the optimized design 3 with rib height e = 1.8 and depth of duct h = 16 after consideration of all the parameters (temperature, velocity, turbulence kinetic energy, and turbulence intensity) at various rib heights and depths of duct. These numerical results will serve as a benchmark for future research to improve the efficacy of solar air heaters.

Plus, they are extremely strong with respect to their size. They have high elastic modulus in comparison with glass fiber. According to the working period, carbon fiber-reinforced polymers possess more potential than those with glass fiber. However, they are relatively expensive as compared to similar fibers, such as glass fiber, basalt fiber, or plastic fiber. Its high quality, light weight, and imperviousness to erosion, make it a perfect strengthening material. Carbon fiber-reinforced composite materials are used to make aircraft parts, golf club shafts, bike outlines, angling bars, car springs, sailboat masts, and several different segments which need to have less weight and high quality.

The energy, exergy, economic analysis of solar chimney and the CO2 mitigations (EEEC) are evaluated in this communication. The improved solar chimney with MS plate and MS box was designed and developed by the author in the CBRI Roorkee. The observations of typical day of December have been taken for the presentation and the whole month data have been used to evaluate the EEEC parameters. The maximum energy efficiency has been observed by 26.68% during 12 hours of the typical day, and at the same time the exergy efficiency has obtained 3.69%. Approximately 2285kWh energy can be saved during a year through solar chimneys. The payback period of an improved solar chimney with MS plate (SCWMSP) is estimated to be less than one year and with MS box (SCWMSB)) it is likely to be one year. CO2 can also be saved with the energy conservation parameter observed saving of 4.37 ton / year CO2 by SCWMSP, on the other hand if SCWMSB have implemented than CO2 would be save by 5.51 ton/year.

As failure due to fatigue is regarded as relevant for the determination of the thickness of the bituminous layers, several criteria exist to predict the technical life time on the basis of empirical observations of the fatigue behaviour in the laboratory or in full-scale tests. All these criteria have in common that relevant stresses or strains within the construction are considered, which appear, in general, either as tensile load at the bottom of the bituminous base course or as compressive load at the top of the subgrade. For bituminous layers, for example, single cracks emerging at the bottom of the base course and developing to the surface are regarded as relevant for the structural fatigue of the pavement. At the surface, these single cracks lead to so-called alligator cracking and, hence, decreasing bearing capacity of the pavement construction.

In this study, the synthesis will be done in small quantity within the lab. Long lifetime, good barrier property, stiffness, tensile strength and tear strength make petrochemical plastics more popular in society. Inspite of many advantages the plastic is proved to be more threatening for the mankind survival. The expected outcome of this project will be the biodegradable plastic which will be a great relief for society. Life begins from birth in which the play toy of newborn baby is plastic then as they grow up everything surrounding them is plastic, the plastic glass, plastic bottles, plastic buckets, plastic box etc. The research work on production of bio plastic using different plant parts will act as substitute for the plastic substances. For the betterment of living creatures and also for the betterment of the environment bioplastics formed from plant parts are better as compared to that of the plastics formed by traditional method. Due to the non-biodegradability of the plastics, they will be ominous for the whole system as the whole system depends on the plastic. Plastic pollution is responsible for the worsening of the habitat of organisms and the human lifestyle. With the help of this study, we will also analyze the properties such as water absorption capacity and bio-degradability. Mass production of bioplastic will be a great solution for plastic pollution.

With the help of ANSYS fluent, two designs are considered to investigate the effect of different rib heights (e = 1, 1.2, 1.4, 1.6, and 1.8) and duct depths (h = 16, 18, 20, 22, and 24). The effects of different parameters such as velocity, temperature, turbulence kinetic energy, and turbulence energy are compared to optimize the performance of designs 2 and 3. It is noticed that except temperature, all other parameters are on the lower side for design 2 as compared to design 3, due to improper air mixing in design 2. The authors presented the optimized design 3 with rib height e = 1.8 and depth of duct h = 16 after consideration of all the parameters (temperature, velocity, turbulence kinetic energy, and turbulence intensity) at various rib heights and depths of duct. These numerical results will serve as a benchmark for future research to improve the efficacy of solar air heaters.

Plus, they are extremely strong with respect to their size. They have high elastic modulus in comparison with glass fiber. According to the working period, carbon fiber-reinforced polymers possess more potential than those with glass fiber. However, they are relatively expensive as compared to similar fibers, such as glass fiber, basalt fiber, or plastic fiber. Its high quality, light weight, and imperviousness to erosion, make it a perfect strengthening material. Carbon fiber-reinforced composite materials are used to make aircraft parts, golf club shafts, bike outlines, angling bars, car springs, sailboat masts, and several different segments which need to have less weight and high quality.

The energy, exergy, economic analysis of solar chimney and the CO2 mitigations (EEEC) are evaluated in this communication. The improved solar chimney with MS plate and MS box was designed and developed by the author in the CBRI Roorkee. The observations of typical day of December have been taken for the presentation and the whole month data have been used to evaluate the EEEC parameters. The maximum energy efficiency has been observed by 26.68% during 12 hours of the typical day, and at the same time the exergy efficiency has obtained 3.69%. Approximately 2285kWh energy can be saved during a year through solar chimneys. The payback period of an improved solar chimney with MS plate (SCWMSP) is estimated to be less than one year and with MS box (SCWMSB)) it is likely to be one year. CO2 can also be saved with the energy conservation parameter observed saving of 4.37 ton / year CO2 by SCWMSP, on the other hand if SCWMSB have implemented than CO2 would be save by 5.51 ton/year.

As failure due to fatigue is regarded as relevant for the determination of the thickness of the bituminous layers, several criteria exist to predict the technical life time on the basis of empirical observations of the fatigue behaviour in the laboratory or in full-scale tests. All these criteria have in common that relevant stresses or strains within the construction are considered, which appear, in general, either as tensile load at the bottom of the bituminous base course or as compressive load at the top of the subgrade. For bituminous layers, for example, single cracks emerging at the bottom of the base course and developing to the surface are regarded as relevant for the structural fatigue of the pavement. At the surface, these single cracks lead to so-called alligator cracking and, hence, decreasing bearing capacity of the pavement construction.

In this study, the synthesis will be done in small quantity within the lab. Long lifetime, good barrier property, stiffness, tensile strength and tear strength make petrochemical plastics more popular in society. Inspite of many advantages the plastic is proved to be more threatening for the mankind survival. The expected outcome of this project will be the biodegradable plastic which will be a great relief for society. Life begins from birth in which the play toy of newborn baby is plastic then as they grow up everything surrounding them is plastic, the plastic glass, plastic bottles, plastic buckets, plastic box etc. The research work on production of bio plastic using different plant parts will act as substitute for the plastic substances. For the betterment of living creatures and also for the betterment of the environment bioplastics formed from plant parts are better as compared to that of the plastics formed by traditional method. Due to the non-biodegradability of the plastics, they will be ominous for the whole system as the whole system depends on the plastic. Plastic pollution is responsible for the worsening of the habitat of organisms and the human lifestyle. With the help of this study, we will also analyze the properties such as water absorption capacity and bio-degradability. Mass production of bioplastic will be a great solution for plastic pollution.
