Abstract

Intrusion detection system (IDS) like firewall, access control and encryption mechanisms no longer provide the much needed security for systems and computer networks. Current IDS are developed on anomaly detection which helps in identifying attacks both known and unknown. Unfortunately, these anomaly-based IDS features high false rate. In a bid to reduce this false alarm rate, this paper proposed an intrusion detection model based on Support Vector Machine (SVM) optimized with Cat swarm optimization (CSO) algorithm. Attribute reduction has been carried out based on Information Gain (IG) and classification has been performed based on the optimized Support vector. The result obtained shows that our model performs well with the least false alarm rate and good accuracy value compared with other classification algorithms evaluated using the same datasets.

Abstract

Face recognition plays a significant role in forensics. At present many face recognition methods has been implemented which extracts the face image of a suspect from moving or still image, then process the extracted face image by comparing it with the faces of criminals stored in a database and finally matching is done. Forensic world is challenging because every day there is increase in the number of crimes. In a crime scene, only partial information about the suspects is available and sometimes facial image of the suspect is not available. In this paper an attempt is made to speed up the process of criminal identification using Haar Classifier. Our proposed work focuses on preprocessing, feature extraction and classification using Haar Classifier. The proposed system can successfully detect and recognize most of the faces which helps to identify the criminals quickly.

Abstract

In 21st century, computers have been playing vital role in engineering and science. Many engineers and scientists utilize computers to solve the complex engineering problems through programming languages, such as C, C++, Java, Fortran, Python, Scilab, MATLAB, etc. Even though these languages are easy to implement in civil engineering discipline such as finite element analysis, structural dynamics, complex soil mechanics problems, design of reinforced concrete structures, steel structures etc., the students are not comfortable with these languages. Generally in Civil Engineering, analysis, interpretation of analysis and design are very important. To solve these problems best suitable languages are MATLAB, Scilab, Python, GNU OCTAVE and FORTRAN. Therefore it is necessary to introduce the programming languages in civil engineering discipline to aid students to solve complex problems by their tutors. In this paper by using singularity functions, the generalized shear force and bending moment diagrams of the beams with different loading conditions via medium MATLAB and GNU OCTAVE have been drawn.

Abstract

Recommender systems have gained its importance because of the availability of enormous online information with the increasing use of internet, online marketing and media outlets. Currently, deep learning has gained appreciable attention in many researches such as natural language processing, artificial intelligence due to high performance and great learning feature representations. The effect of deep learning is also persistent, lately showing its usefulness in retrieval of information and recommenders work which eventually have resulted in the growth of deep learning approaches in recommender system. Hybrid approaches for designing recommender models is gaining popularity in recent years. This paper aims in giving a comprehensive insight of recent research works on recommender systems.

Abstract

IoT is the ever growing concept of connecting physical objects through internet. Internet of Things has the capability to connect everything, everyone and everywhere. It is important to accept the reality that the resources are limited and an optimum utilization of these resource have to be done for sustainability. The wastage is usually highest in the fields of water and electricity consumption. The biggest challenge for businesses is that the processes today are competitive and have to meet the customer demands without slowing down. IoT solutions such as smart irrigation system, automatic street light system and voice controlled home automation are one of the key solutions to the raising challenges. In this study prototypes of the above mentioned solutions have been built and tested to understand the potential of IoT. India predicts about 5 billion IoT connections by 2022, and an economy of $1 trillion by 2025. And the reality is that, it's already 2019 and IoT's growth is slower than predicted because of some of the barriers to implementation. Some of the barrier to the growth of IoT is unawareness of consumers and cost concerns. So it is necessary for businesses to adapt business models which are efficient and suitable for IoT businesses to reach the target segment with a proper channel and a competitive value proposition. In this study a business model framework has been suggested for the prototypes built. As cost is another barrier to the IoT adoption, the cost effectiveness of IoT solutions such as smart lighting system and smart irrigation system has been compared with respect to the traditional solutions.
