OPTIMUM USE OF POLYPROPYLENE FIBERS IMPROVES SOIL PROPERTIES
Soil being the cheapest and readily available construction material has been popular, even though it suffers from being poor in mechanical properties. It has been the constant endeavor of research workers to put forth innovative ideas to improve its mechanical properties to suit the requirements of engineering structures, Vidal in 1968 postulated the new oriented concept of reinforced earth technique. Reinforced earth is a construction material composed of soil fill, strengthened by inclusion of rods, bars, fibers or nets that interact with the soil by means of frictional resistance and act as a coherent mass. It is used in a variety of applications such as retaining structures, embankment, stabilization of subgrade and improvement of soil beneath pavements and footings. Fiber reinforcement technique permits use of natural as well as synthetic fibers for soil reinforcement. In Maharashtra black cotton soil is found in abundance which is highly expansive soil. In present study an attempt has been made to investigate the use of polypropylene fibers for improving properties of locally available soil. The comparison of properties of soil with addition of varying percentages of fibers by dry weight of soil and having different aspect ratios is also carried out. The addition of polypropylene fibers resulted in increase in optimum moisture content and decrease in maximum dry density. Direct shear tests conducted on soil shows increase in value of cohesion and decrease in value of angle of internal friction. With the inclusion of the fibers increase in C. B. R. value and unconfined compressive strength is observed.

This study investigated the engineering properties of low plasticity clay reinforced with glass fibers. A series of tests were conducted including compaction tests and unconfined compressive strength tests with varying fiber contents from 0-1.25%. The results showed that the optimum moisture content increased and maximum dry density decreased slightly with the addition of fibers. The unconfined compressive strength significantly improved with the addition of fibers up to a content of 0.75%, showing a 194% increase over the unreinforced soil strength. Above 0.75% fiber content, the strength began to decrease. Therefore, glass fiber reinforcement was found to be an effective method to improve the strength of low plasticity clay soils.

Application of Jute Fiber in the Improvement of Subgrade Characteristics
For the development of any country, a satisfactory
mode of transport and communication is indispensable. This
can be achieved through a transportation system, which is
economically viable. Economy in road network can be achieved
through economical pavement design. The entire load coming
over the infrastructure is ultimately transmitted to the
subgrade. Load carrying and dispersion capacity of subgrade
soil play a vital role in civil engineering. In case of highway a
weak subgrade results in greater thickness of pavement layer,
so that the stresses on the subgrade are inconsonant with
their load carrying capacity. Empirically flexible pavements
are designed on the basis of CBR value of the subgrade and
traffic on the proposed road. As per IRC recommendation
increase in CBR value from 2.0% to 5.0% reduces the thickness
requirement by 35% for 1.0 msa of traffic. Therefore
improvement in subgrade has always been an area of concern
to highway and geotechnical engineers. In the present study
a series of Proctor Compaction tests and California Bearing
Ratio tests have been carried out on soil mixed with jute fiber.
Jute fibers of different diameters (2 to 8mm) and lengths (0.5
to 2.0 mm) are mixed in the subgrade in different percentage
(0.2 to 1.0%) to find out the optimal quantity. Proctor and

The percent study investigates the effective use of waste plastic as a modifier for cement concrete roads. Civilization produces waste products disposals issue of the waste products is a challenge. Solid waste management is the thrust area. The various waste materials, plastic waste and principle solid waste are of great concern these leads to disposal crisis and environmental pollution. On the other side, road traffic is increasing. The load bearing capacity of the roads are to be increased. Our present work is helping to take care of both these aspects. Plastic waste consists of carry bags cups and disposals. Plastic waste which is cleaned is cut into a size such that it passes through 2.3mm sieve using shredding machine. The aggregates mix is heated and the plastic is coated over aggregates and this coated stones can be used for road constructing. By this process a road of 1km length 3.375m width of single lane can consumes 10,00000 carry bags and road strength is increased and found no pot holes. Commonly soil, aggregates, sand, cement can be used in road construction. Natural materials being exhaustible in nature, its quantity is declining gradually. If our material can be utilized in highway construction, the pollution and disposal problems may be partly reduced. The use of the innovative technology will not only strengthen the road construction but also increase the road life as well as will help to improve the environment. In my research work I have done a thorough study on the methodology of using plastic waste coat over aggregates and presented various tests performed on aggregates.
To Study the Effect of Use of Geosynthetics Fibres in Sub grade Soil
Reinforcements and separation are the two functions of Geosynthetics in which pavement system is used in geogrids. The apertures are used in the products of geogrids.These products are mostly in large size and due to this,they are not used for getting separation of different materials. Gradation has main function to separate two different materials. Still, in theoretically geogrids can also give some separation mathods, but in a limited amount. In pavements, geogrids used separation method which is a secondary function or we can say it is use for some sepration of different materials and in reinforcement, geogrids used the primary function in pavements and geogrid used to improve the mechanically properties of engineering like M25 Grade Concrete. The reinforcement mechanisms associated withgeogrids. Er. Kapil Soni | Er. Sunil Kumar | Er.

Bio-enzyme is a natural, non toxic, non flammable, non-corrosive liquid enzyme formulation fermented
from vegetable extracts that improves the engineering qualities of soil, facilitates higher soil compaction densities
and increases stability. Enzyme catalyze the reactions between the clay and the organic cat-ions and accelerate the
cat-ionic exchange process to reduce adsorbed layer thickness. For other types of chemical stabilization,
chemicals are mixed with soil, which is difficult to mix thoroughly, but bio-enzyme is easy to use as it can be
mixed with water at optimum moisture content and then it is sprayed over soil and compacted. Recently many
Bio-enzymes have emerged as cost effective stabilizers for soil stabilization. One such bio-enzyme, Terrazyme,
has been used in the present work to study its effect on the CBR value of the Black Cotton soil. The tests
conducted in this project are specific gravity, plastic limit, liquid limit, CBR and standard proctor test. In this
project, local soil was mixed with Terrazyme with different dosages i.e. 0.25 ml per 100 ml of water, 0.50 ml per
100 ml of water, 0.75 ml per 100 ml of water, and 1 ml per 100 ml of water was mixed subjected to various tests
as mentioned. All the testing programs have given optimum value at 0.5 ml terrazyme per 100ml of water. The
pavement thickness values reduced by improving the sub grade strength (CBR value).The cost analysis done for
this project by using CBR values of the experiments with the reference of pavement design catalogue MORD
specification table. The pavement construction value is reduced 30% of the total cost with the help of my
laboratory testing results.
Design of stone dust stabilized road
This study evaluated the use of stone dust to stabilize soil for road construction. Laboratory tests were conducted on soil samples with varying percentages of stone dust added. The optimum stone dust content was found to be 30% based on compaction and CBR tests. Pavement thickness designs were calculated for unstabilized soil and soil stabilized with 30% stone dust according to Indian code specifications. The results showed that using stone dust to stabilize the soil reduced the required pavement thickness by about 115 mm or 18%, which could provide substantial cost savings for road construction.
Papercrete Bricks An Alternative Sustainable Building Material
A large amount of non-renewable resources is consumed by the construction industry throughout the world. Everyday tons of waste papers are discarded as landfill or dump sites than those recycled. It is learnt that it takes about fifteen trees to make a ton of paper which means that 720 million trees are used once and then buried as landfills each year. In order to address these issues it has become imperative to push the boundaries of research in the field of innovative sustainable construction materials. This study is one such kind of efforts. Papercrete is a new composite material comprising of waste papers and cement. In this investigation, an attempt is made to produce an alternative material using waste papers. This could help eradicate a few of the environmental hazards caused by the construction industry. But there is no proper code for the mix proportioning of papercrete bricks. Therefore, a mix proportion of [Cement: Paper : Sand] 1:1.15:1.3 was chosen on trial and error basis. All the necessary engineering properties are studied and compared with the conventional bricks and discussions on its potential uses are made.

This document reviews literature on using waste materials like structural concrete and polypropylene fibers to improve the engineering properties of soil. It finds that structural concrete waste fines and polypropylene fibers can individually improve soil properties like strength and density. However, using them together as a composite material has potential to further enhance properties like bearing capacity and shear strength. The review identifies gaps like limited research combining these wastes and a need for more studies on polypropylene fiber reinforcement. It concludes that utilizing these wastes for soil stabilization can reduce environmental impacts while improving soil properties and decreasing construction costs.

The performance of Flexible Pavement depends on the functions of the component layers especially Sub-base layers. Generally Sub-base layers are made up of natural soils like Gravels. Frequently gravel soils composed of high amount of fines which causes plasticity characteristics with adsorption of moisture under heavy loads and repeated traffic. Excess deformation leading several failure which require huge investment of money for their repairs. To reduce the excess deformation of the gravel soils and to increase the life period of the pavement there is a need to arrest their plastic characteristics and stabilization is one such techniques to improve the gravel soils by addition of industrial wastes. In this connection Crusher Dust has been selected as a Stabilizer to improve their qualities. Various percentage of Crusher Dust was added to gravel soil and tests like Plasticity, Compaction and Strength tests were conducted. By the addition of Crusher Dust Plasticity Characteristics were reduced and CBR values were improved. Addition of 25% of Crusher Dust make the mixes low-plastic and 35% of Crusher Dust make the mixes non-plastic, where high CBR values attained. Hence from the test results it is identified that addition of 25%-35% of Crusher Dust make the gravel soils meet the specification of MORTH as a sub-base material.

Effect of geopolymer on the strength of black cotton soil
Abstract
This paper presents in the improvement of problematic soils in a environmental friendly method. The present paper geopolymer to stabilize a soft soil. Geopolymer is an alkali activated solution prepared by combining sodium hydroxide(NaOH) with the sodium silicate solution(Na2SiO3). The sodium hydroxide solution is prepared to 12M concentration and Na2SiO3/NaOH ratio of 2.5. The geopolymer increases the strength of the black cotton soil by geopolymerisation. The geopolymerisation process involves three separate but interrelated stages. During initial mixing the alkaline solution dissolves silicon and aluminium ions from the amorphous phases of the feedstock. In this solution, neighboring silicon or aluminium hydroxide molecules then undergo a condensation reaction, where adjacent hydroxyl ions from these near neighbors condense to form an oxygen bond linking the molecules and a free molecule of water. The application of mild heat causes these “monomers” and other silicon and aluminium hydroxide molecules to poly-condense or polymerise, to form rigid chains or nets of oxygen bonded tetrahedra. In the present study geopolymer is treated with the black cotton soil. The effect of geopolymer on strength characteristic of Black cotton soil have been studied for a curing period of 7days 15days and 28days. The compressive strength of black cotton soil increases with geopolymer dosage and curing.. The density of black cotton soil also increases with the increase in geopolymer. The test result indicates that geopolymer is very effective in stabilizing the soft soil. An attempt has been made to study the properties of soil treated with geopolymer Key words : Geopolymer, Black cotton soil, polycondensation reaction.

Performance Study of Square Footing Resting Over Geo-Grid Reinforced Sand
Decreasing availability of good construction sites and increasing construction activities for infrastructural developments throughout the world has forced the civil engineers to utilize unsuitable sites or weak soil. So for sustainable infrastructural development, there is a need to utilize these type of unsuitable land by the use of ground improvement techniques. There are different ground improvement techniques to stabilize the poor ground in which soil reinforcement is an effective and reliable technique. The objective of the present study was to determine the effects of the geo-grid reinforcement on the bearing capacity of sand. The model tests have been conducted using square footing at u/B=0.25 & 0.55. The average relative density kept up throughout all the tests is 65%. The sand is reinforced by multiple layers (1, 2, 3 & 4) of geo-grid. The ultimate bearing capacity of sand with square footing was computed by load-settlement curve. By these load-settlement curve, an appreciable increase in bearing capacity of sand was observed as the depth to the first layer of reinforcement increased. The optimum depth of placement of the first layer was 0.5B.

On the other side, road traffic is increasing. The load bearing capacity of the roads are to be increased. Our present work is helping to take care of both these aspects. Plastic waste consists of carry bags cups and disposals. Plastic waste which is cleaned is cut into a size such that it passes through 2.3mm sieve using shredding machine. The aggregates mix is heated and the plastic is coated over aggregates and this coated stones can be used for road constructing. By this process a road of 1km length 3.375m width of single lane can consumes 10,00000 carry bags and road strength is increased and found no pot holes. Commonly soil, aggregates, sand, cement can be used in road construction. Natural materials being exhaustible in nature, its quantity is declining gradually. If our material can be utilized in highway construction, the pollution and disposal problems may be partly reduced. The use of the innovative technology will not only strengthen the road construction but also increase the road life as well as will help to improve the environment. In my research work I have done a thorough study on the methodology of using plastic waste coat over aggregates and presented various tests performed on aggregates.
To Study the Effect of Use of Geosynthetics Fibres in Sub grade Soil
Reinforcements and separation are the two functions of Geosynthetics in which pavement system is used in geogrids. The apertures are used in the products of geogrids.These products are mostly in large size and due to this,they are not used for getting separation of different materials. Gradation has main function to separate two different materials. Still, in theoretically geogrids can also give some separation mathods, but in a limited amount. In pavements, geogrids used separation method which is a secondary function or we can say it is use for some sepration of different materials and in reinforcement, geogrids used the primary function in pavements and geogrid used to improve the mechanically properties of engineering like M25 Grade Concrete. The reinforcement mechanisms associated withgeogrids. Er. Kapil Soni | Er. Sunil Kumar | Er.

Bio-enzyme is a natural, non toxic, non flammable, non-corrosive liquid enzyme formulation fermented
from vegetable extracts that improves the engineering qualities of soil, facilitates higher soil compaction densities
and increases stability. Enzyme catalyze the reactions between the clay and the organic cat-ions and accelerate the
cat-ionic exchange process to reduce adsorbed layer thickness. For other types of chemical stabilization,
chemicals are mixed with soil, which is difficult to mix thoroughly, but bio-enzyme is easy to use as it can be
mixed with water at optimum moisture content and then it is sprayed over soil and compacted. Recently many
Bio-enzymes have emerged as cost effective stabilizers for soil stabilization. One such bio-enzyme, Terrazyme,
has been used in the present work to study its effect on the CBR value of the Black Cotton soil. The tests
conducted in this project are specific gravity, plastic limit, liquid limit, CBR and standard proctor test. In this
project, local soil was mixed with Terrazyme with different dosages i.e. 0.25 ml per 100 ml of water, 0.50 ml per
100 ml of water, 0.75 ml per 100 ml of water, and 1 ml per 100 ml of water was mixed subjected to various tests
as mentioned. All the testing programs have given optimum value at 0.5 ml terrazyme per 100ml of water. The
pavement thickness values reduced by improving the sub grade strength (CBR value).The cost analysis done for
this project by using CBR values of the experiments with the reference of pavement design catalogue MORD
specification table. The pavement construction value is reduced 30% of the total cost with the help of my
laboratory testing results.
Design of stone dust stabilized road
This study evaluated the use of stone dust to stabilize soil for road construction. Laboratory tests were conducted on soil samples with varying percentages of stone dust added. The optimum stone dust content was found to be 30% based on compaction and CBR tests. Pavement thickness designs were calculated for unstabilized soil and soil stabilized with 30% stone dust according to Indian code specifications. The results showed that using stone dust to stabilize the soil reduced the required pavement thickness by about 115 mm or 18%, which could provide substantial cost savings for road construction.
Papercrete Bricks An Alternative Sustainable Building Material
A large amount of non-renewable resources is consumed by the construction industry throughout the world. Everyday tons of waste papers are discarded as landfill or dump sites than those recycled. It is learnt that it takes about fifteen trees to make a ton of paper which means that 720 million trees are used once and then buried as landfills each year. In order to address these issues it has become imperative to push the boundaries of research in the field of innovative sustainable construction materials. This study is one such kind of efforts. Papercrete is a new composite material comprising of waste papers and cement. In this investigation, an attempt is made to produce an alternative material using waste papers. This could help eradicate a few of the environmental hazards caused by the construction industry. But there is no proper code for the mix proportioning of papercrete bricks. Therefore, a mix proportion of [Cement: Paper : Sand] 1:1.15:1.3 was chosen on trial and error basis. All the necessary engineering properties are studied and compared with the conventional bricks and discussions on its potential uses are made.

Review on Improvement of Engineering Properties of Soil using Structural Conc...
This document reviews literature on using waste materials like structural concrete and polypropylene fibers to improve the engineering properties of soil. It finds that structural concrete waste fines and polypropylene fibers can individually improve soil properties like strength and density. However, using them together as a composite material has potential to further enhance properties like bearing capacity and shear strength. The review identifies gaps like limited research combining these wastes and a need for more studies on polypropylene fiber reinforcement. It concludes that utilizing these wastes for soil stabilization can reduce environmental impacts while improving soil properties and decreasing construction costs.

The performance of Flexible Pavement depends on the functions of the component layers especially Sub-base layers. Generally Sub-base layers are made up of natural soils like Gravels. Frequently gravel soils composed of high amount of fines which causes plasticity characteristics with adsorption of moisture under heavy loads and repeated traffic. Excess deformation leading several failure which require huge investment of money for their repairs. To reduce the excess deformation of the gravel soils and to increase the life period of the pavement there is a need to arrest their plastic characteristics and stabilization is one such techniques to improve the gravel soils by addition of industrial wastes. In this connection Crusher Dust has been selected as a Stabilizer to improve their qualities. Various percentage of Crusher Dust was added to gravel soil and tests like Plasticity, Compaction and Strength tests were conducted. By the addition of Crusher Dust Plasticity Characteristics were reduced and CBR values were improved. Addition of 25% of Crusher Dust make the mixes low-plastic and 35% of Crusher Dust make the mixes non-plastic, where high CBR values attained. Hence from the test results it is identified that addition of 25%-35% of Crusher Dust make the gravel soils meet the specification of MORTH as a sub-base material.

Effect of geopolymer on the strength of black cotton soil
Abstract
This paper presents in the improvement of problematic soils in a environmental friendly method. The present paper geopolymer to stabilize a soft soil. Geopolymer is an alkali activated solution prepared by combining sodium hydroxide(NaOH) with the sodium silicate solution(Na2SiO3). The sodium hydroxide solution is prepared to 12M concentration and Na2SiO3/NaOH ratio of 2.5. The geopolymer increases the strength of the black cotton soil by geopolymerisation. The geopolymerisation process involves three separate but interrelated stages. During initial mixing the alkaline solution dissolves silicon and aluminium ions from the amorphous phases of the feedstock. In this solution, neighboring silicon or aluminium hydroxide molecules then undergo a condensation reaction, where adjacent hydroxyl ions from these near neighbors condense to form an oxygen bond linking the molecules and a free molecule of water. The application of mild heat causes these “monomers” and other silicon and aluminium hydroxide molecules to poly-condense or polymerise, to form rigid chains or nets of oxygen bonded tetrahedra. In the present study geopolymer is treated with the black cotton soil. The effect of geopolymer on strength characteristic of Black cotton soil have been studied for a curing period of 7days 15days and 28days. The compressive strength of black cotton soil increases with geopolymer dosage and curing.. The density of black cotton soil also increases with the increase in geopolymer. The test result indicates that geopolymer is very effective in stabilizing the soft soil. An attempt has been made to study the properties of soil treated with geopolymer Key words : Geopolymer, Black cotton soil, polycondensation reaction.

Performance Study of Square Footing Resting Over Geo-Grid Reinforced Sand
Decreasing availability of good construction sites and increasing construction activities for infrastructural developments throughout the world has forced the civil engineers to utilize unsuitable sites or weak soil. So for sustainable infrastructural development, there is a need to utilize these type of unsuitable land by the use of ground improvement techniques. There are different ground improvement techniques to stabilize the poor ground in which soil reinforcement is an effective and reliable technique. The objective of the present study was to determine the effects of the geo-grid reinforcement on the bearing capacity of sand. The model tests have been conducted using square footing at u/B=0.25 & 0.55. The average relative density kept up throughout all the tests is 65%. The sand is reinforced by multiple layers (1, 2, 3 & 4) of geo-grid. The ultimate bearing capacity of sand with square footing was computed by load-settlement curve. By these load-settlement curve, an appreciable increase in bearing capacity of sand was observed as the depth to the first layer of reinforcement increased. The optimum depth of placement of the first layer was 0.5B.

ASSESSMENT OF LIQUEFACTION POTENTIAL OF SOIL USING MULTI-LINEAR REGRESSION MO...
The Standard Penetration Test (SPT) is the most widely used in-situ test throughout the world for subsurface geotechnical investigation and this procedure have evolved over a period of 100 years. Estimation of the liquefaction potential of soils is often based on SPT test. Liquefaction is one of the critical problems in the field of Geotechnical engineering. It is the phenomena when there is loss of shear strength in saturated and cohesion-less soils because of increased pore water pressures and hence reduced effective stresses due to dynamic loading. In the present study, SPT based data were analysed to find out a suitable numerical procedure for establishing a Multi-Linear Regression Model using IBM-Statistical Package for the Social Sciences (IBM SPSS Statistics v20.0.0) and MATLAB(R2010a) in analysis of soil liquefaction for a particular location at a site in Lucknow City. A Multi-Storeyed Residential Building Project site was considered for this study to collect 12 borehole data sets along 10 km stretch of IIM road, Lucknow, Uttar Pradesh (India).

Effect of discrete_fiber_reinforcement_on_soil_ten
This document describes a study that investigated the effect of discrete fiber reinforcement on soil tensile strength. An innovative tensile testing apparatus was developed to directly measure the tensile strength of fiber-reinforced soil specimens. A series of direct tensile tests were performed on specimens with varying fiber content, dry density, and water content. The results showed that the inclusion of discrete fibers significantly increased the tensile strength and ductility of soil. Specifically, tensile strength increased with higher fiber content, dry density, and lower water content. The mechanism by which fibers improve tensile strength is through fiber pull-out resistance due to interfacial mechanical interaction between the fiber surface and soil matrix.

Inclusion of coconut coir fiber in soil mixed with coal ash
Abstract An experimental study is conducted on local soil i.e. silty sand (SM) mixed with varying percentage of coal ash and coconut coir fiber. Unconfined compressive strength (UCS) and California bearing ratio (CBR) tests are conducted on the soil mixed with coal ash/coir fiber/ both. The percentage of coal ash by dry weight of soil is taken as 20%, 30%, 40% and 50%. A significant increase in UCS and CBR value is observed for addition of 20% of coal ash in the soil.UCS value is maximum (1.81 kg/cm2) for 20% coal ash mixed with soil. The unsoaked and soaked CBR values as 10.5% and 5.6% increase to 27.7% and 14.6%, respectively. Rate of increase in CBR values decreased after further addition of coal ash beyond 20%. Randomly mixed coconut coir fiber is included in optimum soil-coal ash mix (i.e. 80% soil and 20% coal ash) and varied as 0.25, 0.50, 0.75 and 1.0%. UCS value increases substantially with inclusion of coconut coir fiber in soil - coal ash mix. The optimum percentage of soil-coal ash-coir fiber mix is arrived at 79.75:20:0.25 (by weight). Adding of these waste materials (coal ash + coconut coir fiber) results in the increase strength of soil and less thickness of pavement due to increased CBR of mix and hence saving of the stone aggregates in base and sub-base course for sustainable development in construction of highway. Keywords: Coal ash, Coconut coir fiber, Unconfined compressive strength (UCS) and California bearing ratio (CBR).

Harnessing WebAssembly for Real-time Stateless Streaming Pipelines
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
A review on techniques and modelling methodologies used for checking electrom...
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Recycled Concrete Aggregate in Construction Part III
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
