Abstract: Cryptography includes two phases: Encryption and Decryption. Encryption and Decryption schemes based on Kamal Transform are unable to provide more security to communicate the information. RSA (Rivest–Shamir–Adleman) algorithm is a popular public key algorithm. RSA cryptosystem is based on the difficulty of factoring large integers. This paper aims to introduce a method for cryptography using RSA algorithm and Kamal Transform to improve security of communication.

Abstract: Cryptography is a popular technique to achieve confidentiality of information. Cryptography has two phases: Encryption and Decryption. Encryption is the process of transforming plaintext into ciphertext, whereas decryption is the reverse. Encryption and Decryption schemes based on applications of Kamal Transform are unable to provide more security to communicate the information. ElGamal algorithm is public key algorithm which depends on the discrete logarithm problem. This paper aims to introduce a method for cryptography using ElGamal algorithm and Kamal Transform to improve security of communication..

Abstract: Blockchain has emerged as a key technology for ensuring reliability and security in several application areas primarily including the healthcare sector. Blockchain is a distributed ledger where blocks of transactions are connected in a chain using the cryptographic hash function of the previous block, making it an append-only structure. Any modification on any of the blocks will generate different hash values in other blocks in a cascading manner and different link relations. In this way the blockchain achieves immutability and security. Blockchain also involves consensus mechanisms in order to ensure synchronization among blocks and agreement between existing nodes......

Abstract: Today digitalization plays an important role in day-to-day life. Many things become easy by digitalization. In this digitalization, lots of data is shared over the open network. In case of sensitive data, security of this data is very important. Main security goals are confidentiality of data, authenticity of sender and non-repudiation. This paper proposes Digital Signature algorithm using Elliptic Curve Digital Signature Algorithm (ECDSA) and ElGamal encryption techniques..

Abstract: L'intégration des Technologies de l'information et de la communication(TIC) dans les infrastructures pédagogiques congolaises est à leur début, l'arrivée du système LMD dans notre système éducatif vient mettre au grand jour les forces et faiblesses de notre environnement pédagogique. Dans cet article, nous montrons l'apport que peut jouer le cloud computing dans le support et l'amélioration de notre système éducatif, en appuyant l'utilisation des nouvelles technologies de l'information et de télécommunications dans l'enseignement congolais. Le cloud computing permet aux institutions d'enseignement d'implementer des architectures capables de fonctionner dans notre environnement social qui lui connait l'instabilité de l'énergie éléctrique, le manque de maintenance preventive, etc. Le Cloud Computing, ce modèle informatique distribué, configurable de manière dynamique, offrant une puissance de calcul élevée et un espace de stockage consistant au travers des réseaux de communication, peut être un alié de taille dans les applications pour la didactique en RDCongo.

Abstract: The Web Development is essential part of computer it provide the user interface and the information through whole world. In this paper it is discussed to updating of the technology use to develop a web page. The general idea of the new version of HTML (Hyper Text Markup Language), i.e. HTML5, and other tools presented in this paper is the formal specification and the establishment of uniform solutions for technologies and functionalities which have already been in use through various hacks and plug-ins proposed by web developers. Many of these functionalities will now be implemented in browsers. The applications can access these functionalities through newly defined application programming interfaces.........

Abstract: In recent years, with the improvement of people's living standards, cars have gradually entered people's daily life, thus driving the rapid development of the automotive industry. At the same time, there are many kinds of cars in the market, and there are many performance indicators to measure the quality of cars. Therefore, this study will explore the internal relationship between the types of cars and their performance indicators through multivariate statistical methods, and cluster all kinds of cars according to these indicators. For example, they are divided into three grades of good quality, medium quality and good quality, which can provide guidance for the majority of car buyers and sellers..

Abstract: Background: Nowadays, traditional universities and colleges are currently confronting a number of issues, including increased student enrollment, limited physical infrastructure, admissions delays, rising educational costs, and so on. While different schools are addressing these challenges in different ways, Massive Open Online Courses (MOOCs), a relatively new technology, is increasingly being examined as a way to give higher education to a large number of individuals at potentially cheaper rates.MOOCs play a critical role in the development of skills and abilities in a variety of study fields.The extent to which these skills and competencies are acquired is determined by the learner's effective interactions with the knowledge found within the system.This is, however, tied to connectivism, the theory of the digital era, also reviewed in this study.This study, therefore..........

Abstract: The development of technology is very fast. Technology can be used to diagnose various diseases, one of which is heart disease. To be able to predict, analyze and recognize patterns, a new science emerged, namely data mining. Data mining is a process of gathering information from big data. In data mining there are several methods, one of which is classification. Before classification is carried out on some attributes of the data it may not be relevant if it is included in the classification process. For this reason, the selection of which attributes is a process to find out which attributes are relevant to use and which are not. Attribute selection uses information gain and forward selection algorithms which are then implemented............

Abstract: Now a day's world Machine learning is very popular not only among academic researchers but also among industry researchers as well. In last couple of decades Machine Learning gain tremendous achievements, one of the most famous success was the victory of Deep Blue over then-World Chess Champion Garry Kasparov in 1997, but still there is lot of work which is not explored or need improvements. This technique (Machine learning) is often feasible, cost effective and scalable then manual programing. In this article, we focus on the elementary.......
