ENHANCING HYBRID SECURITY APPROACH USING AES AND RSA ALGORITHMS

Network safety has become an important issue in recent years. Encryption has been developed as a solution and plays an important role in the security of information systems. Many methods are required to secure the shared data. The advanced internet, networking firms, health information and the cloud applications have significantly increased our data every minute. The current work focuses on cryptography to provide the protection for sensitive data that exchanged between personal users, companies, organizations, or in the cloud applications and others during the transfer of data across the network. Firstly, Data sent from sender to network receiver must be encrypted using the cryptographic algorithm. Secondly, the recipient shows the original data using the decryption technique. This paper presents three encrypting algorithms such as AES, RSA and hybrid algorithms, and their efficiency is compared based on the analysis of the time. Results of the experiments show that the hybrid algorithm is better in term of security.

With the increasing interest in literature on continuous practices, it is important to systematically review and synthesize the approaches, tools, challenges, and practices reported for adopting and implementing continuous practices.
Peat Ecosystem: Teachers' knowledge and perception, and its integration in learning biology

The improper uses of peatlands degrade the lands, making them vulnerable to fire. Restoration and conservation of Indonesian peatlands have not succeeded, yet the forest fires tend to increase in severity and frequency. Therefore, it is urgent to have more systematic efforts to conserve the peatlands through education, mainly in schools. This study aims to assess the knowledge and perceptions of high school biology teachers about the peatland ecosystem and identify the potential for integrating peatland-associated materials in learning biology. Data and information were collected through observation, online questionnaires, literature reviews, and focus group discussions. The data were analyzed qualitatively to reveal the biology teacher's knowledge and perceptions about peatlands. Although peatland is a vital resource on the east coast of Jambi Province, most biology teachers in the region do not have good knowledge about peatland. However, the teachers aware of the importance of integrating peatland material in learning biology. They argue that the integration facilitates students to understand the surrounding environment, including the peatland. Therefore, in the long run, they could actively involve in protecting and conserving the peatland. This research has identified several peatlands-associated materials that are relevant to be integrated into biology learning.
Topological protection of highly entangled non-Gaussian two-photon states

Abstract We study theoretically the evolution of entangled non-Gaussian two-photon states in disordered topological lattices. Specifically, we consider spatially entangled two-photon states, modulated by Laguerre polynomials up to the 3rd order, which feature ring-shaped spatial and spectral correlation patterns. Such states are discrete analogs of photon-subtracted squeezed states, which are ubiquitous in optical quantum information processing or sensing applications. We find that, in general, a higher degree of entanglement coincides with a loss of topological protection against disorder, this is in line with previous results for Gaussian two-photon states. However, we identify a particular regime in the parameter space of the considered non-Gaussian states, where the situation is reversed and an increase of entanglement can be beneficial for the transport of two-photon quantum states through disordered regions.
Determining patterns of student graduation using a bi-level learning framework

The practice of data science, artificial intelligence (AI) in general, has expanded greatly in terms of both theoretical and application domains. Many existing and new problems have been tackled using different reasoning and learning methods. These include the research subject, generally referred to as education data mining (or EDM). Among many issues that have been studied in this EMD community, student performance and achievement provide an interesting, yet useful result to shaping effective learning style and academic consultation. Specific to this work at Mae Fah Luang University, the pattern of students’ graduation is determined based on their profile of performance in different categories of courses. This course-group approach is picked up to generalize the framework for various undergraduation programmes. In that, a bi-level learning method is proposed in order to predict the length of study before graduation. At the first tier, clustering is applied to derive major types of performance profiles, for which classification models can be developed to refine the prediction further. With the experiments on a real data collection, this framework usually provides accurate predictive outcomes, using several conventional classification techniques.
FORMATION OF GRAPHIC COMPETENCE OF THE HIGHER EDUCATION SEEKERS BY MEANS OF COMPUTER-ORIENTED TECHNOLOGIES

The role of graphic competence in the training process of future teachers of labor education and technology has been substantiated in this article. Examples of students' use of the acquired knowledge in Descriptive Geometry and Engineering Graphics in further educational and practical activities have been established. There are reading drawings of products (parts) for their manufacture; design and execution of graphic images of products (parts); development of a logical sequence of the technological process for the manufacture of the product; designing a garment pattern, etc.&#x0D; The growing role of machines with digital program control (DPC) is taken into account and the role of graphic representation of the part (product) in digital format for their manufacture on such machines is also investigated. It is proposed to provide the emphasized training of students to perform drawings of parts (products) by means of graphic editors with the prospect of their manufacture on machines with DPC. The purpose of the article is to reveal the features of preparation of future teachers of labor education and technology to perform drawings of product details in graphic editors with the subsequent manufacture of these objects on machines with digital program control. &#x0D; The peculiarities of training students in Computer Graphics at Volodymyr Hnatiuk Ternopil National Pedagogical University during studying of disciplines «Descriptive Geometry, Drawings and Computer Graphics», «Computer Graphics and Multimedia» have been analyzed. It is determined that students are not able to fully master Computer Graphics due to the lack of hours and the large number of commands and functions that are provided by such computer programs. It is proposed to enhance the preparation of students for mastering computer graphics through the independent implementation of students' drawings of product details using a graphic program in extracurricular time in the form of an individual educational research tasks (IERT). The expediency of making drawings of product parts by means of a graphic program with their subsequent manufacture by a machine with digital program control (DPC) has been substantiated. &#x0D; Plywood is proposed as a construction material for the design of the products by means of graphic editors with the subsequent manufacturing by machines with DPC. The structure of IERT is proposed: to make drawings of details of a product according to the instruction; provide a “photo report” of the sequence of drawings according to the instructions with a short description; to change the design of the product based on the knowledge and skills formed by making drawings according to the instructions. An example of IERT instructions for students is given. It involves the use of KOMPAS-3D. The phone stand is considered as a sample of performance by students for IERT.

In doing this action research, the researcher considers phases that involve each cycle. Those are planning, action, observation, and reflection. Every phase is done based on the researcher’s ideas on the research. This study is aimed at exploring the improvement of the teaching and learning process writing procedure text using picture series. It is also intended to identify the improvement of students’ ability in writing procedure text using picture series. Based on the research findings and the discussions in section four, some conclusions can be drawn as follows: the use of picture series promotes the improvement of students’ ability in writing procedure text and can elevate the students’ interest or motivation in the classroom. Picture series is very good in providing the idea for the students to write. The students’ works are also more persistent to the idea as compared to when not using the picture series. The pictures also attract more attention from the students and motivate students to get involved in the classroom interaction with the teacher and among themselves. For the detailed works of the students, the use of appropriate diction and the improvement of vocabulary mastery is also the effect of the use of the picture series. Further, the changes of the pictures in every meeting make the students remain interested in participating in the teaching and learning process because they do not feel bored.
Importance of software architectures in mobile projects

Mobile projects often exhibit architectural issues. In this paper, we survey three different types of persons (instructors, students, and developers) to find out how often do those who write code struggle with architectural issues and how are those issues impacting their work. Our focus was on mobile projects, but to have a comprehensive overview, we have also questioned students - who might become mobile developers, to see if they understand the importance of architecture in their projects. We were also interested in instructors and their experience with the students on whether or not they lack architectural knowledge. Our research has found that all the questioned developers struggle with architectural issues in their projects, over 60% of the students had to re-write a project due to architectural issues, and over 94% of the questioned instructors stated that students have architectural issues in the projects they develop. The vast majority of the participants to the survey (100% of instructors, 100% of students, and 90% of developers) agreed that a tool that could validate the software architecture would help them.
Distributed Recommendation Considering Aggregation Diversity

Recommender systems (RSs) are popular in e-commerce as they suggest different kinds of items for different users. Most existing research works focus on how to improve the accuracy of recommender systems. Recently, some recommendation ranking techniques have been proposed to obtain more diverse recommendations for all the users. In this paper, the authors propose design a distributed mechanism for improving the aggregated recommendation diversity and define three new metrics to evaluate the diversity of RSs. To avoid the disclosure of information to a central agency, a distributed mechanism is designed to collect user ratings. To increase the diversity of set recommendations, user-based and item-based weighted methods are proposed. The tasks of them are to deal with non-ratings by weighting the common ratings and calculating the weighted cosine similarities to predict the unknown ratings.
A Proposal to Improve the Bit Plane Steganography based on the Complexity Calculation Technique

The video steganography technique is being studied and applied a lot today because of its benefits.In particular, the video steganography technique using Bit-Plane Complexity Segmentation (BPCS) has increasingly proven its effectiveness compared to other methods.In this paper, based on the theoretical basis of the BPCS method, we propose a new method to improve the efficiency of the steganography process.Accordingly, our improvement proposal in this paper is improving the complexity formula of the bit planes.Our new formula not only has improved the steganographic thresholds in the bit planes to find more planes hiding secret information, but also has ensured the amount of information hidden in the video and their safety.The experimental results in the paper have not only demonstrated the effectiveness of our proposed method but also provided a new mechanism for digital image analysis in general and video steganography techniques in particular.
IMPLEMENTATION OF BLOM’S KEY PREDISTRIBUTION SCHEME BY USING ELLIPTIC CURVE CRYPTOGRAPHY

Cryptography, along with its various methods is used to serve the security communication purpose. Cryptography is said to be secure if the encryption key is hard to break by the attacker. Initially, Blom’s Key pre-distribution uses an integer finite field which makes this scheme easy to be intervened by attackers and criminal activists. Hence, this study suggests implementing the Elliptic Curve Cryptography to better enhance the security of the original Blom’s. In this proposed scheme, points generated from the elliptic curve will be appointed as public identifiers to be used in the original scheme. The private key and session key of each user are generated using the addition law mathematical operation with public identifiers assigned. Two users who intend to communicate with each other will obtain a common session key. Overall, the modification of Blom’s Key pre-distribution scheme will be presented in this study.
Navigation in multi-robot systems based on the behavioural fuzzy controller

Controlling a highly dynamic multi-robot system (DMRS) is a challenge scientific and technological in constant expansion.Our goal in this article is to control the DMRS and used the local interactions between the robot and its environment to produce a form of advanced intelligence in the selection of behaviours.For this, we have developed a reactive controller based on fuzzy behaviours using the concept of fuzzy logic.This controller allows mobile robots to move in an unknown environment and, at the same time, to resolve the navigation conflicts.The simulation results obtained on the pioneer P3-DX robot clearly show the effectiveness of the proposed fuzzy controller.
Iterative Optimal Sufficient Dimension Reduction for Conditional Mean in Multivariate Regressio

Recently, Yoo and Cook (2007) developed an optimal version of Cook and Setodji (2003).When predictors are not highly skewed, the Yoo-Cook approach can be improved, especially with small samples, by iteratively estimating the inner product matrix used in their method without changing their asymptotic results.Since highly skewed predictors are often transformed for normality in sufficient dimension reduction literature, the proposed method can have more useful application in practice than Yoo and Cook (2007).

Grounding, Quantifiers, and Paradoxes

Abstract The notion of grounding is usually conceived as an objective and explanatory relation. It connects two relata if one—the ground—determines or explains the other—the consequence. In the contemporary literature on grounding, much effort has been devoted to logically characterize the formal aspects of grounding, but a major hard problem remains: defining suitable grounding principles for universal and existential formulae. Indeed, several grounding principles for quantified formulae have been proposed, but all of them are exposed to paradoxes in some very natural contexts of application. We introduce in this paper a first-order formal system that captures the notion of grounding and avoids the paradoxes in a novel and non-trivial way. The system we present formally develops Bolzano’s ideas on grounding by employing Hilbert’s ε -terms and an adapted version of Fine’s theory of arbitrary objects.
GEOPHYSICAL MODELING OF THE DISTRIBUTION OF ATMOSPHERIC POLLUTANTS IN ANDIJAN BASED ON THE EQUATIONS OF AERODYNAMICS

Ensemble Kalman Filter estimates shear stress and seismic slip rates in synthetic laboratory experiment

&amp;lt;p&amp;gt;Our ability to forecast earthquake events is hampered by limited information of the state of stress and strength of faults and their governing parameters. Ensemble data assimilation methods provide a means to estimate these variables by combining physics-based models and observations taking into account their uncertainties. In this study, we estimate earthquake occurrences in synthetic experiments representing a meter-scale laboratory setup of a straight-fault governed by rate-and-state friction. We test an Ensemble Kalman Filter implemented in the Parallel Data Assimilation Framework, which is connected with a 1D forward model using the numerical library GARNET. A perfect-model test shows that the filter can estimate shear stresses, slip rates and state &amp;amp;#952; acting on the fault even when simulating slip rates up to m/s and can thus be used for estimating earthquake occurrences. We assimilate shear stress and slip-rate observations, representing measurements obtained from shear strain gauges and piezoelectric transducers sensors, and their uncertainties acquired at a small distance to the fault in the homogeneous elastic medium. In this study we evaluate how the Ensemble Kalman filter estimates the state and strength of the faults using these observations, and assess the relative influence of assimilating various observations. The results suggest that the data assimilation improves the estimated timing of the earthquake occurrences. The assimilation of the shear stress observed in the medium improves in particular the estimates of the state &amp;amp;#952; and the shear stress on the fault, while assimilating observations of velocity in the medium improves the slip-rate estimation.&amp;lt;/p&amp;gt;
