Permeable Pavements
-Aman Negi ; Vikram Kaintura
Over the past few years cities and suburbs have become larger and densely populated, areas to be covered by vegetation has now been replaced by the Infrastructure, parking lots and walkways the absence of these natural surfaces has greatly disrupted the cycle of water the excessive use of impervious coverings has left cities with the challenge of managing increased run of volumes Bank erosion, Flooding and water clogging. Today these problems post consider of the risks to the sustainable development of cities and suburbs areas its a serious matter that require immediate attention and reliable solution. Permeable Pavements is a simple and lasting solution that imitates the original hydrological characteristic of soil its primary function allows runoff water pass through it directly into the ground being filtered by different layers of aggregate prior to returning it into the soil this helps reduce the volume of runoff rainwater that reduces the strain on the rainwater management system the reduced amount of volume helps to avoid overloads and flooding. It improves water quality and helps ground water recharge and also reduces the heat island effect and can be used where vegetation is not suitable. Permeable Pavements is a comprehensive resource for the proper design, construction and maintenance of permeable pavement systems that provide a transportation surface and a best management practice for storm water and urban runoff. A cornerstone for low impact development (LID) and sustainable site design, permeable pavements are considered a green infrastructure practice. They offer many environmental benefits, from reduced storm water runoff and improved water quality to better site design and enhanced safety of paved surfaces. Commonly used for walkways, driveways, patios, and low-volume roadways as well as recreational areas, parking lots, and plazas, permeable pavements are appropriate for many different land uses, particularly in highly urbanized locations.

Machine Learning Techniques to Detect and Classify Ransomware
-Pooja N ; Pavithra S; Shreya S; Sharmili S
The system mainly focuses on the malware where it is a type of malicious software called ransomware designed in such a way to block access to a computer system until a sum of money is paid. The automatic classification system which has high-performance, high accuracy and efficiency based on multi-feature selection fusion of machine learning is proposed in this project. The manual heuristic inspection of malware analysis is not considered to be effective and efficient when it is compared against the high spreading rate of malware which is a serious threat. Hence, using machine learning techniques the automated behavior based malware detection is considered to be a profound solution. The classifiers used in this project are K-Nearest Neighbors (KNN), Random Forests, and Decision Tree. Since, many antiviruses have heavy impact on the user system and sometimes they are not able to detect new emerging harmful threats like ransomware and on the other hand, light weight antiviruses are not so effective in detecting and preventing malwares. As the data security with no heavy impact on the user system is our main concern. Our model can be a cloud based malware classification model. Therefore, without installing any third party application on user system, we can test and predict whether any suspicious file is a malware or not. Read More...

This paper describes the performance analysis of solar based flat plate collector. Flat plate collector (FPC) is widely to heat water in the home for bathing, washing and heating, and can even be used to heat outdoor swimming pools and hot tubs. The Flat plate collector (FPC) is a kind of a heat exchanger which transforms solar radiation into heat energy which is then used to transfer the heat to the Fluid flowing through the pipe. The system is designed with dimensions 100*100cm in such a way the water flows from inlet to outlet through pipe of length as 14m with the serpentine configuration in order to have a steady flow of water through the pipe. The water flows through the pipe by natural circulation. The main components of FPC are Absorber Plate, Glazing Cover and Thermal Insulation. The aim of this study is to evaluate the optimum mass flow rate of water at the efficiency is maximum. The efficiency of the FPC decreases with an increase in mass flow rate of water. The test was conducted for three flow rates 0.5L/min, 1L/min and 1.5L/min. It was found out that the maximum efficiency is when the fluid flows at the rate of L/min because if the fluid flows slower then it gets more time to absorb the heat.

Study on the Stress-Strain Behaviour of High Strength Glass Fibre Reinforced Self-Compacting Concrete under Axial Compression with & without Confinement
-Abhishek Goswami ; Nitish Jauhari
A self-compacting concrete (SCC) is the one that can be placed in the form and can go through obstructions by its weight and without the need for vibration. Although there are visible signs of its gradual acceptance in the Middle East through its limited use in construction, it has yet to explore the feasibility and applicability of SCC in new construction. The contributing factors to this reluctance appear to be lack any supportive evidence obits suitability with local marginal aggregates and the harsh environmental conditions. Concrete is a vital ingredient in infrastructure development with its versatile and extensive applications. It is the most widely used construction material because of its mouldability into any required structural form and shape due to its fluid behavior at an early age. However, there is a limit to the fluid behavior of normal fresh concrete. Thorough compaction, using vibration, is normally essential for achieving the required strength and durability of concrete. Inadequate compaction of concrete results in a large number of voids, affecting performance and long-term durability of structures. Self-compacting concrete (SCC) provides a solution to these problems. As the use of Concrete becomes more widespread the specifications of concrete-like durability, quality, and compactness of concrete becomes more important. Self -Compacting Concrete is a recently developed concept in which the ingredients of the concrete mix are proportioned in such a way that it can flow under its weight to fill the formwork and passes through the congested reinforcement without segregation and self-consolidate without any mechanical vibration. Self–Compacting Concrete (SCC) is a very fluid concreter and a homogeneous mixture that solves most of the problems related to ordinary concrete. This specification helps the execution of construction components under high compression of reinforcement. Read More...

To Study the Effect of Addition of Nano Ni Particles as Catalyst on Microstructure and Properties of MgO C Refractory
-Durgesh Rai
Magnesia-carbon (MgO-C) refractory bricks have been used in the slag line of ladles due to its superior slag penetration resistance and excellent thermal shock resistance at high temperatures. However, the life of this bricks has become limited on prolonged use due to its poor oxidation resistance as well as low strength at high temperatures. Thus, the physical and chemical properties of MgO-C refractories could be improved by the use of nanotechnology and addition of suitable additives nano range. Metallic nano-Ni particles has been recognized as one of the most effective nanomaterial to be used in MgO-C refractory as it has large surface area and density which lead to the development of various in-situ ceramic phases in the refractories which enhances its properties. Hence, the present work deals with the improvement of the physical and chemical properties of MgOC refractories with the addition of nano-Ni particle as catalyst. In this work, a set of experiments was carried out in order to standardize amount of nano-Ni addition in MgO-C refractory system. Here nano sized metallic Nickel particles are added in different amount (2,4,6 and 8 wt.%) in MgO-C refractory with fixed content of graphite (12 wt.%) and antioxidants B4C and metallic aluminum powder each (1wt.%). So that only the effect of nano-Ni variation in the MgO-C refractories can be evaluated. Total five compositions has been made by varying the composition of nano-Ni from (0-8 wt.%) and then compare the properties of nano-Ni added MgO-C brick with the conventional MgO- C brick, which contain 12wt.% graphite only, there is no nickel added in it. Out of the different samples containing nano-Ni in MgO-C brick, MC6 sample (containing 6 wt.% nano-Ni) exhibits better compaction, so has high bulk density (BD), cold crushing strength (CCS) and hot modulus of rupture (HMOR).

Conversion of sun energy into another form is highly complex. For this purpose, Photo-Voltaic Panel are used which convert it into Direct Current (D.C). Convention fixed panel extract maximum energy from 12 noon to 2 noon which result is less efficiency. Therefore, building a automatic solar tracker is need for an hour. PV panels face perpendicular to the direction of sun rays to extract maximum energy and efficiency which is fulfilled by linear actuators. Read More...

Utilization and Characterization of Jhama Coal
-Ravi Mehrotra ; Puspraj Singh; Shasikant Jaiswal; Rohit Maurya; Sanjay Kumar
Natural coke is a kind of fossil fuel with calorific value of 18–28 MJ/ kg. There are abundant natural coke reserves in the world, but at present it is abandoned and needs research and development for its utilization. Thermogravimetric analysis (TG) can be done to investigate pyrolysis characteristics of natural coke. The effects of the heating rate, the final pyrolysis temperature, the particle diameter, and the operating pressure on the pyrolysis process of natural coke can be examined with pressurized thermogravimetry. Scan electron microscopy show that the natural coke at higher temperature has better porous structure, which is beneficial to volatilization, and a better reduction activity. Decrease in the particle size leads to more volatile release. The pressure has less effect on pyrolysis under lower temperature, while the effect becomes stronger when the temperature is higher than a given point. In Indian coalfields huge amounts of natural coke have been produced due to magmatic intrusions. Jharia Coalfield in eastern part of India alone contains approximately 2000 Mt of baked coking coal as a consequence of these intrusions in the form of discordant and concordant bodies. Natural coke is characterized by the presence of low volatile matter and high ash contents and organic constituents showing isotropy and anisotropy. Natural coke is smokeless because the volatile matter escaped off, it can be processed for gasification or can be used directly for domestic ovens and in blast furnace. Natural Coke may be used to make synthesis gas, a mixture of carbon monoxide and hydrogen. Syngas; Water gas: a mixture of carbon monoxide and hydrogen, made by passing steam over red-hot coke (or any carbon-based char), Producer gas: a mixture of carbon monoxide, hydrogen, and nitrogen, made by passing air or air-steam blast over red-hot coke (or any carbon-based char). Natural coke is also used for heat shielding in space craft’s when mixed with other materials. Jhama coal or Natural coke is excluded resources due to difficulty in mining and its low calorific value. Natural coke coexists with coal in the coal bed, but is discarded or left in the mine without scheduled exploitation because of lack of effective utilization technology, which would cause tremendous energy waste and harm to the environment. Therefore, considering the challenge of energy crisis sources, it is necessary to utilize it for power generation. But it can be used into blast furnace with blending it, in formation coke from bituminous coal in coke ovens. Gasification of Natural coke can be done in fluidized bed reactor with using suitable catalyst, to increase yield and heating value of product gas. Characterization of natural coke can be done by-proximate analysis, ultimate analysis and H.G.I (hardgroove grindability index), ash fusion temp, G.C.V. (gross calorific value), swelling index no. , dilation etc. Read More...

Behaviour of Coconut Shell Aggregate (CSA) Concrete at Elevated Temperature
- A. S. J. Smith ; A. Ibrahim; M. J. Garba; B. Muhammad; S. M. Ishaq
This paper attempts to study the mechanical behaviour of coconut shell aggregate (CSA) concrete subjected to elevated temperatures when coconut shell (CS) is used to replace coarse aggregate at 0, 10, 20 and 40% in concrete. The coconut shell used was obtained by breaking the shells into smaller sizes of less than 20mm after the fibres were removed. In order to produce control concrete samples with a minimum compressive strength of 15N/mm2 at 28 days curing age, mix ratio of 1:2:4 and water-cement ratio of 0.55 were adopted alongside Absolute Volume Method (AVM) to prepare the concrete mix proportions for this research. The specific gravity of the concrete materials were determined as well as the workability of the fresh coconut shell aggregate concrete at various replacement using slump tests. Compressive strength of 48 samples prepared at various CSA replacements using 100mm x 100mm x 100mm cube mould and cured for 28 days was determined after 30 minutes exposure to temperatures of 100, 300 and 500oC. Splitting tensile strength of 18 samples prepared at various CSA replacements using 200mm x 300mm cylinder mould and cured for 28 days was also determined after 30 minutes exposure to 500oC temperature. The results of this study showed that at 10% replacement and 500oC temperature, CSA concrete exhibits good behaviour in compressive strength and splitting tensile strength as it retained 67.3% and 53.7% of its strength respectively; as well as having a higher strength reduction coefficient (Kc(θ)) of 0.673 in compressive strength compared to the 0.60 allowed for siliceous aggregates in BS EN 1992-1-2 [26]. However, slump results showed that CSA concrete has a very low workability. So, CSA can be used up to 10% to replace coarse aggregate in concrete to serve in non-load primary application areas.

Password Based Circuit Breaker for Lineman Protection using Microcontroller 8051
- Hemanth Kumar M.H.
Electrical line man safety in power systems is a major concern. Therefore, a new concept of password-based system has been introduced. Fatal electrical accidents while repairing the power line to the line man are increasing day by day. The accidents occur due to the lack of communication and coordination between the maintenance staff and the electric substation staff. Therefore, to ensure safety of lineman, password-based circuit breakers can be installed. If certain sections of the line need to be repaired then a password has to be entered through a matrix keypad to switch the circuit breaker ON/OFF. When the line is repaired, the lineman again enters the password, if the password is matched with the circuit breaker, then it will turn ON/OFF particular section of the line during maintenance, without any external interference from substation staff and can thus, help in saving human lives.

-Md. Zobair Alam ; Rifat Ullah Ronak
The aim of this project is to find the Biological Oxygen Demand (BOD) of the wastewater generated from the tanneries of Hazaribagh and the mixture of tannerys wastewater with Buriganga river water. Hazaribagh is a principal area of Dhaka Metro bounded by Buriganga River on the west and Bangladeshs largest leather processing zone is situated here. Hazaribagh area, widely known for its tannery industry, has been listed among the highest 10 polluted places on earth. The tanneries use backdated processing methods and dump toxic wastes including the cancer-causing toxin hexavalent chromium, into Dhakas mainstream Buriganga. The settlements of tannery workers have developed around the contaminated streams, ponds and canals. Workers and residents of Hazaribagh also face a number of less severe but common health problems of skin and respiratory diseases every day as well as acid burns, rashes, dizziness and nausea. Informal leather recyclers who burn scraps of leather to produce a number of consumer products also heavily pollute the air. Tanneries discharge the effluents and wastes into the river system causing an outsized area of acid sludge alongside the flood protection embankment and therefore the liquid wastes are dumped in the river through flood control regulator-cum-sluice. During dry season dissolved oxygen in the river water is nil because of heavy pollution and no fish or other aquatic animals can live in this condition. Many experimental results showed that tannery wastewater has a very high concentration of organic matter, solids, sulphates, sulphide and chromium in tannery effluent. Read More...

Experimental Study on Self-Healing Bacterial Concrete By using E-Coli Bacteria
-Mr. Megharaj Patil ; Mr. Pratik Jadhav; Mr. Aniket Khandare; Mr. Utkarsh Danawle ; Prof. Sneha Bhende
Concrete is an adaptable material having lowered tensile & shear strength. Basically concrete is brittle material and contains lots of micro-cracks present in the body. The elasticity of concrete is fairly constant at low stress levels but starts decreasing at higher stress levels as matrix starts cracking. Concrete has a very low coefficient of thermal expansion and concrete shrinks. All concrete structures will crack to some point, due to shrinkage and tension. Concrete which is under load of forces for long duration of time, creep of concrete may happen. Carbonate- producing bacteria have provide lots of benefits as a promising, natural, environmental friendly novel technique to improvement of concrete characteristics, considerable research has been conducted on utilizing microbial-induced carbonate precipitation to overcome several concrete problems such as crack repair, reduction and modification of porosity, and permeability. Furthermore, bacterial carbonate precipitation (bio deposition) has shown positive influences on compressive strength improvement of concrete, it also reduces water absorption and carbonation of concrete as an alternative surface treatment. As part of metabolism, some bacteria produces enzyme urease which catalyzes the hydrolysis of urea to generate carbonate ions without an associated production of protons which leads to CaCO3 precipitation in presence of calcium ions. Therefore, bacteria cells not only provide a nucleation site for CaCO3 precipitation in presence of calcium ions. Read More...
