Geopolymer concrete with replacement of silica fume and foundry sand

A concrete use around the world is second only to water. The production of ordinary Portland cement contributes 5-7% of total greenhouse gas emission. It also consumes large amount energy. Hence it is essential to find the alternative to cement. Silica fume it is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production. It is also rich in silica and alumina. In this paper, silica fume is used to produce a geopolymer concrete. Geopolymer is a material resulting from the reaction of a source material that is rich in silica and alumina with the alkaline solution. Geopolymer concrete is totally cemented free concrete. In geopolymer, silica fume act as the binder and alkaline solution act as an activator. Silica fume and foundry sand are totally replaced and alkaline activator undergoes polymerization process to produce aluminosilicate gel. Alkaline solution used for present study is the combination of sodium hydroxide (NaOH) and sodium silicate (Na2Sio3) with ratio 3. A grade chosen for the investigation were M25.The mix was designed for molarity of 8M. Hot air curing is done by placing the specimens in the electric oven at 60ºC for the 24hours duration and 7days 14 days and 28days test is carried after heating. The geopolymer concrete specimens were tested for their compressive strength, flexure strength and split tensile test. Experimental investigations have been carried out on workability, the various mechanical properties of GPCs.

Credit card fraud detection using Naïve Bayes model based and KNN classifier

Machine Learning is the technology, in which algorithms which are capable of learning from previous cases and past experiences are designed. It is implemented using various algorithms which reiterate over the same data repeatedly to analyze the pattern of data. The techniques of data mining are no far behind and are widely used to extract data from large databases to discover some patterns making decisions. This paper presents the Naïve Bayes improved K-Nearest Neighbor method (NBKNN) for Fraud Detection of Credit Card. Experimental results illustrate that both classifiers work differently for the same dataset. The purpose is to enhance the accuracy and enhance the flexibility of the algorithm.

Chatbot for education system

The purpose of this paper is to develop an automated system which gives a reply to a user query on behalf of a human for the education system. It can give an answer to each and every query asked by the end user. Existing chatbots such as facebook chatbot, WeChat, Natasha from Hike, Operator, etc. were giving reply from its local database. But our approach is to focus on the local database as well as web database and also to make system scalable, user-friendly, highly interactive. Various techniques such as machine learning, NLP, pattern matching, data processing algorithms are used in this paper to enhance the performance of the system.

Underwater optical wireless communication analysis using blue laser diode

In the proposed system, a 450nm blue laser diode is directly modulated by 16 Quadrature Amplitude Modulation (QAM) data which are orthogonal. The simulation is done by assuming underwater with ambient noise present in the underwater covering a distance of 20 meters. Due to the presence of noise and attenuation of the wireless medium, the optical power is decreased to a great extent. The photodetector converts the weak optical signal to electrical signal. The phase and amplitude of the signal is change caused by noise present in it. A Butterworth filter is implemented to obtain the original signal at the receiver side. It is shown that the output binary data has change due phase due to the corruption of the noise.

Good governance and digital India

Good Governance and Digital India is a new concept in this two existing India. Both words have their own importance. Today every country is moving towards good governance and digitization. Good governance day is celebrated in our country on the birthday of former Prime Minister ATAL BIHARI VAJPAYEE (December 25). When we talk about government rule, the importance of digitization increases, Today the world has become so digital that we can sit in one place and get information from all over the country, if we use digital in good governance, then we sit in one place and get information about that place The place where the accident happened, today is the time of the Internet, which is moving digital India forward. Today, at the present time, global governance is sometimes talked about, that is why it is possible for global governance to achieve global governance, neither does it require more public power nor is it the concept of global rule First is in vain as a fantasy, but now it is moving from fantasy to reality.

Tollgate automation system

RFID based automatic toll gate control system allows the vehicle drivers to pass the toll tax booths without stopping at the toll booths and also designed to automatically keep track the vehicle movement. The toll amount is deducted from the smart card. In this is card will be allowed three toll gate for without balance amount. The main aim of our project is to Reduce the time consumption at the toll gates by automating the toll collection process and the user will not wait to give the money because the driver has to just show the RFID card in- front of the card reader. And then the RFID based automatic toll gate control system will open the gate to pass through. The main benefit of the system is User doesn’t have to carry the money each time. The user will link to the RFID card and will use this card each time my travels.
