Cryptography is a technique to make information unreadable for unauthorized users. Today, building a secure channel is one of the most challenging areas for research in communication systems. Many forms of public key cryptography are available, but it requires more complex techniques and needs more computational power. Artificial Neural Network (ANN) and cryptography together can make a great help in field of networks security. Neural networks’ most important property is their generalization capability. This ability ensures they produce reasonable results when they are fed with inputs not previously encountered. This makes them extremely useful for many applications. The other important property of ANNs is parallel implementation. Each layer is paralleled, so they can independently implement certain functionality. A special property of neural networks is confusion, which is caused by the non-linear structure of networks. The output, therefore, depends on the input in non-linear and complicated cases. Thus, it is not easy to define the exact input. As a result of this confusion property, ANNs could be preferable used for cipher design.

Outliers are suspicious values because they are smaller or larger than the given values. The detection of outliers is important task in interest of data mining that realization that outliers as the key discovery from very large databases. Outlier’s detection is important because of various reasons such as human faults, system error or instrument error etc. Outlier detection techniques are divided into two categories: supervised and unsupervised. Supervised technique assumes the availability of training data set for normal as well as anomaly. Unsupervised technique does not require training data. This approach takes as input a set of data and finds outlier within the data. Sometimes good outliers give useful information for the discovery of new knowledge. Bad outliers are noisy data point. In this paper we propose a novel approach for outlier analysis along with review of some existing outlier detection techniques. In this paper we used some statistical properties to find out outlier. We also find that what the effects are when we consider analysis of data with outlier and without outliers. In this paper we proposed a novel approach in which we used some mathematical relationship between data after deleting the outliers.

The most commonly used material in construction industry is Concrete. Now a days the use of concrete for modern infrastructure is in high demand. Cement is the main constituent of concrete plays a vital role in concrete production. In India, the cement consumption has grown well with a growth rate of about 6.1% every year (annually). Hence, an alternative material to partially replace cement was initiated to complete the needs of local community. Animal bone powder which has same chemical composition same as of cement can be replaced with cement. Due to continuous utilization of natural materials like coarse aggregate and fine aggregates for making concrete we are facing different problems like lack of availability of these materials, because of their high demand and I some areas restriction from the local government for the extraction of the natural materials. Due to this the price of natural materials are increasing rapidly, due to high price of natural materials ultimately the cost of construction is high. To overcome this problem many researchers are finding the replacement for cement and coarse aggregate. Through the various study it is found that waste materials from sea like sea shells having properties similar to coarse aggregate can be used in production of concrete. we bought sea shells at very cheap price from coastal area. Here coarse aggregate is partially replaced to sea shell in percentage to coarseaggregateby10 %. Similarly the replacement for cement is made by the animal bone powder. The waste quantity of animal bones has impacted the environment which are unusual to see all over the world. The primary aim of the research is to investigate the effects of varying dosage replacement of cement by animal bone powder (ABP) in the normal concrete production. The bone samples collected from M.I. Industries Thane Mumbai, we found that After cleaning and drying, the bone samples burned in the Furnace. The average required energy to burn the animal bone obtained at a temperature of 340°C. The burnt bone was allowed to cool before grinding in a hammer mill and sieving. There were four proportions prepared to start from 0% (as control specimen), 5%, 10%, 15% dosage increment by weight of bone powder, and evaluated the normal concrete strengths of M-30 grade concrete. The laboratory test results indicated the chemical analyses of bone powder composed similar compounds of oxide in cement but slightly lesser in content. Likewise, the effects of replacing animal bone on the properties of cement such as consistency and setting time remained within the acceptable limits of the Standard Specifications. As we know the lack of natural materials hence we can use these two materials as partial replacement of coarse aggregate and cement ,hence we form a new concrete On the other hand, the results of compressive strength, flexural strength, and the tensile strengths significantly declined from the control specimen during the dosage increment of the replacement made. Therefore, the optimum dosage of bone powder indicated 10% by weight to replace cement content in normal concrete mix production.

Security of data has been the biggest concern in the past couple of years. The existing systems are not quite helpful in securing the sensitive data of the users. It has been difficult to secure and manage data that has been uploaded to the cloud. The encryption that is used in existing systems is not enough and can be the biggest flaw in security scams. To overcome this flaw or problem the proposed system will be using a hybrid cryptography approach. The system will be using multiple encryption algorithms to encrypt the data that will be stored on the cloud or uploaded to the cloud. When the user will upload the file to the cloud, the server will get the file and split it into three files. Each file will be then sent to particular encryption algorithms. The three encryption algorithms that the system will be using are AES256, RC4, Blowfish. These 3 algorithms are good and efficient for this type of system. The first file part will be provided as input to the AES256 algorithm, the second file will be provided as input to the RC4 algorithm and the last file will be provided to the blowfish algorithm. All the files will be then uploaded to the different Aws s3 buckets. The keys that will be generated will be embedded into respective images and stored into image storage services. This will provide more security to the user data. During the download process the whole procedure will be reversed. When the user requests for the file, the server will refer to the metadata and request the file from the cloud. The encrypted file will be split into 3 parts and each file will be provided as input to the respective algorithm. The files will be decrypted using the respective algorithm and then merged to a single original file that will be sent to the user as a response. The whole process will take more time so to tackle this, the system will be using node js for performing asynchronous calls and functioning.
