Redevelopment of Pen Bus Stand
-Siddhesh V Dambe ; Namrata Vijay Mokal; Deepak N Shah; Adesh Tudilkar; Y. R. Galinde
The implementation of the act rectified matters to an extent. Thus continued the state of affairs till 1948, when the then Bombay State Government, with the late Morarji Desai as the home minister, started its own state road transport service, called State Transport Bombay. And the first blue and silver-topped bus took off from Pune to Ahmednagar. The driver and conductor used to wear khaki uniforms and peak caps. There were 10 makes of buses in use then - Chevrolet, Fort, Bedford, Seddon, Studebaker, Morris Commercial, Albion, Leyland, Commer and Fiat. In 1950, a Road Transport Corporation Act was passed by the Central Government and it delegated powers to states to form their individual road transport corporations with the Central Government contributing one-third of the capital. The Bombay State Road Transport Corporation (BSRTC) thus came into being, later changing its name to MSRTC with the re- organization of the state. The MSRTC has decided to introduce a concept of redeveloping of bus station along with commercial complex. As many as six stations were identified for the first phase. The concept, is now, being extended to other cities. MSRTC officials said that the project of redevelopment aims at providing high standard amenities for passengers. Gates, parking spaces for auto rickshaws and private vehicles, provision of passenger facilities such as waiting space and toilets etc. In addition to this, the complex of bus station will have commercial establishments. MSRTC's investment in the project is in the form of land only, which will be made available for development the successful bidder. Read More...

Mind Reading Computer
-Piyush Diwakar Mishra ; Rushikesh Atmaram Thombare
Mind studying is the way to realize or discover the other’s mental states. The easiest way for thought studying can be performed with the aid of simply looking and appreciation the facial expressions. For instance the smile can provide us an expression of happiness. But nowadays, it can also be viable that now not solely one humans can apprehend the other’s mental state however also a laptop might recognize the mental states of the people. This paper describes the ways how a computer would possibly speculate the mental kingdom of a human and thus becomes the thought reading computer. This paper emphasizes on the ways by using which a pc may speculate the mental state, First method is by Facial Expression Analysis (FEA) and the second by the usage of a Futuristic Headband. The machine would possibly be able to react to instructions just by way of say, shifting a dot across a TV screen. So a long way the S.R.I, computer has been taught to recognize the seven distinct commands—Up, Down, Left, Right, Slow, Fast and Stop. Read More...

Application of Machine Learning in enhancing the Scope of Optical Coherence Tomography for Glaucoma Diagnosis
-Saptarshi Mukherjee ; Jayanti Chaudhary; Abhishek Mandal
An early diagnosis of glaucoma is essential to limit its unwanted progression. OCT is an important tool which provides a means of obtaining objective measurements of the optic nerve which is highly useful in the process of ascertaining the diagnosis of glaucoma. Optical coherence tomography (OCT) scan aided by machine learning (ML) algorithms can assist in this process. The purpose of this study is to review the scope of simultaneous utilization of OCT and ML in the diagnosis of glaucoma. This is a prospective study based on assessing the literature review of the subject under question. The incorporation of ML into OCT is certainly helpful in the predictive elimination of some of the patients based on the past database analysis. Nevertheless, it is important to remain prudent while comparing measurements to the normative database of OCT as the database itself may not be able to reflect the true optometric parameters of the patients being evaluated. Owing to a considerable risk of artifacts, it is always prudent to review an entire OCT scan for the purpose of isolating computational errors. Advanced ML algorithms are capable of acting upon the pre-defined criteria programmed into the system. With this assistance from artificial intelligence, OCT scans can safely diagnose the majority of people with a kind of disease. Read More...

Automatic Pneumatic Bumper with Safety Control System
-Suyog Dandge
Nowadays vehicle accidents is the major problem. This system is based on the automatic bumper activation system is known as “Automatic pneumatic bumper with safety control systemâ€. This system is assembled on four wheeler vehicle. This provide safety for vehicle as well as victims after accident. When vehicle meets with an accident the major possible damage is due to the burning of engine. The burning of engine happens due to the leakage of fuel after the accident. Basically engine runs on three flows, which are fuel flow, carburetor flow, and battery flow. If we cut any one of these three flows engine stops working. This burning of engine after accident can be avoided by blocking the engine. In this system pneumatic cylinders are mounted inside the bumper. When obstacle hits the car pneumatic circuit completes and gives feedback to the control unit. Then the control unit cuts any one of three flows. This total cycle completes within the fraction of second. In this way the safety of driver and other victims is improved to very large scale by decreasing possibility of burning of engine.

Analysis of Genetic Algorithm in Infinite Monkey Problem
-Mayur Garg ; Isha Negi; Deepti Gupta
Revolutionary enhancements have been made in the field of Artificial Intelligence and Machine Learning. One of the key aspects of the latter is to solve problems of which little is known in advance. Such problems encompasses a very broad search space and it is, more often than not, tedious to design a situation specific algorithm. In such cases, adaptive methods such as Evolutionary algorithms are preferred. One of the most widespread used evolutionary algorithms is Genetic Algorithms. Genetic algorithms mimic the processes involved in natural selection and evolution to repeatedly improve on its solution and arrive at an optimal or near optimal result. Genetic algorithms, or evolutionary algorithms in general, are extensively used to solve many search and optimisation problems specially NP-hard problems where it is computationally infeasible to arrive at an optimal solution but quite often a near optimal solution is sufficient. Other problems which can be solved by genetic algorithms include problems where it is unclear as to how an algorithm must be designed to solve it. Such problems such as the designing character movement in games can be tackled by Genetic algorithms as long as we can define a fitness function to evaluate the effectiveness of our result. In the suggested system, we have aimed to implement Genetic Algorithms to tackle the Infinite Monkey Problem. We have aimed to understand the basic functioning of the simple Genetic Algorithm used and have expected to find a correlation of various parameters in the Genetic Algorithm used such as the Length of the input string, Size of the population, Mutation Rate, Elitism and Scoring pattern with the associated efficiency of the algorithm in arriving at a solution by varying these parameters in a suitable range.

Experimental Analysis on Effect of Variable Aspects of Polypropylene Fibre on Reinforced Concrete Strength
-Deepak Baranwal ; M.C. Paliwal
Concrete is very weak in tension, has low ductility and very little resistance capacity to cracking. Fibres in a cementitious composite play a key role in reducing these issues. As a result, adding fibres to concrete enhances and strengthens its resilience, and these issues may be solved by using polypropylene-fibre. Replacement of cement and sand are the present issue in the current construction scenario, because of higher cost and environment pollutants. Polypropylene fibres are industrial by-product produced from manufacturing of plastics. Use of this plastic waste fibre does not just lower the cost of construction but also helps to reduce the impact on environment by consuming the material generally considered as waste product. Then, Initially the material tests such as time for the first and last settings, consistency, fineness modulus, compressive strength, specific gravity test for cement, sieve analysis, specific gravity, water absorption, silt content, bulk density, void ratio, test for coarse and fine aggregate are conducted and then, the compatibility of the Polypropylene fibre with the conventional material is tested using basic material testing. On the basis of properties & availability of polypropylene fibre (from various sources like plastic waste) in Bhopal region as well as in other places of India, a feasible way to use this waste product is evaluated without affecting strength characteristics of concrete. This dissertation represents the results of an experimental Analysis to investigate the impact on which Cement is partially replaced. Read More...

A Review Paper on Damage Detection in Reinforced Concrete Beam Using Acoustic Emission Technique
-Rugved Jitendra ; Vaishali M Bogar
Evaluating the integrity of concrete structures is an essential procedure to ensure structural safety and durability. Structural assessment is the integral part of civil engineering When any structure is to be constructed it should be designed for 20-30 years lifespan. But after some year structural assessment is required for the structure. Structures can deteriorate in service as a result of heavy loads, fatigue and aging of the structures. Serviceability & performance of RC structure is hampered because of deterioration of concrete such as corrosion, poor construction aging, overloading, chemical reaction, natural disasters (Earthquake). Effect on structural capacity and durability because of damage propagation is time dependent process. Deterioration of existing concrete structures has raised the need for advanced non-destructive testing (NDT) techniques to determine the current structural state of the members and to assist in the evaluation of repairs. Non-destructive testing (NDT) is needed for localizing and characterizing the growing damage in existing structures and also for quality control of new structures. Visual inspection is a commonly used method however it is not suitable for early detection of damage and very dependent on the experience of the inspector. NDT is also required for testing new structures to ascertain safety and serviceability of the members prior to service. Among all the NDT test Acoustic Emission (AE) technique is used for real time damage detection in structure. Damage severity of reinforced concrete (RC) structure can be diagnosed using acoustic emission (AE) technique. With the help of AE technique corrosion can be detect in the structure. Detecting real time damage, locating the crack propagation in beam sample & with the help of RA value and Avg Frequency crack classification will be easier. Availability of data of Cumulative AE hits and Amplitude of signals help to detect corrosion in beam sample will be easy, these are the expected outcomes of study. Due to use of AE system periodic structural assessment will be automatically eliminated and it will help to reduce assessment cost. Nowadays AE system were already installed on massive structure such as bridges, dams, steel buildings etc. to detect real time damage and to rectify it on time. Read More...
