Health Change Detection Using Temporal Transductive Learning

Industrial equipment, devices and patients typically undergo change from a healthy state to an unhealthy state. We develop a novel approach to detect unhealthy entities and also discover the time of change to enable deeper investigation into the cause for change. In the absence of an engineering or medical intervention, health degradation only happens in one direction — healthy to unhealthy. Our transductive learning framework, known as max-margin temporal transduction (MMTT), leverages this chronology of observations for learning a superior model with minimal supervision. Temporal Transduction is achieved by incorporating chronological constraints in the conventional max-margin classifier — Support Vector Machines (SVM). We utilize stochastic gradient descent to solve the resulting optimization problem. We prove that with high probability, an $$\epsilon $$ -accurate solution for the proposed model can be achieved in $${\text {O}}\left( \frac{1}{\lambda \epsilon }\right) $$ iterations. The runtime is $${\text {O}}\left( \frac{1}{\lambda \epsilon }\right) $$ for the linear kernel and $${\text {O}}\left( \frac{n}{\lambda \epsilon }\right) $$ for a non-linear Mercer kernel, where n is the number of observations from all entities — labeled and unlabeled. Our experiments on publicly available benchmark datasets demonstrate the effectiveness of our approach in accurately detecting unhealthy entities with less supervision as compared to other strong baselines — conventional and transductive SVM.

PEDAGOGICAL CONDITIONS FOR THE FORMATION OF CROSS-CULTURAL COMPETENCE OF FUTURE PRIMARY SCHOOL TEACHERS

In modern conditions, the problem of multicultural education is very relevant to the formation and development of cross-cultural competence of a primary school teacher. The problem of the formation of cross-cultural competence is currently acquiring special social significance. Particular attention is paid to highlighting the problem of constructive transfer of knowledge in a multicultural environment. This may be due to the processes of globalization taking place in the world, integration in the educational space, as well as the low level of cross-cultural competence of people. The formation and development of cross-cultural competence is important in the system of foreign language education, especially in the process of professional training of a teacher. The teacher must be ready to solve urgent educational problems always associated with the need to train and educate students. Students can be from different ethnic and social groups with different cultural values, traditions and lifestyles. Accordingly, the education system should first of all strengthen intercultural ties and harmony in Kazakhstan, which entails a change in the requirements for modern graduates of higher educational institutions with a high level of competence in the field of cross-cultural relations. In this regard, the purpose of this study is to identify the pedagogical conditions for the formation of cross-cultural competence of future primary school teachers, capable of understanding and accepting values, having a developed cross-cultural self-awareness, capable of intercultural interaction, inherent in other cultures.
Module-LWE-Based Key Exchange Protocol Using Error Reconciliation Mechanism

Lattice-based key exchange protocols have attracted tremendous attention for its post-quantum security. In this work, we construct a Module-LWE-based key exchange protocol using Peikert’s error reconciliation mechanism. Compared with Kyber.KE, our key exchange protocol reduces the total communication cost by 96-byte, i.e., 3.2% <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"> <mo>∼</mo> </math> 6.1%, under the different parameter sets, and without reducing the post-quantum security levels. Moreover, our key exchange protocol slightly reduces the probability of session key agreement failure and the time consumed by modular multiplication of numbers and ring elements by approximately 30%. Thus, the key exchange protocol in this paper is more suitable for the lightweight communication systems.

State-Constraint Transition: A Language for the Formal Specification of Dynamic Cyber-System Requirements

Existing formal languages for the specification of self-adaptive cyber-physical systems focus on re-configuring the system-to-be depending on its current context, to satisfy the user’s requirements, that is by dynamically composing the software’s structure and behavior. While these approaches specify context-sensitive requirements, they rarely consider their run-time dynamic and scalable nature. The State-Constraint Transition (SCT) modeling language, introduced in this paper, provides an answer to the problems linked to the specification of dynamic requirements by introducing the concept of configuration states, in which requirements are translated into constraints. The expressiveness of existing approaches is thus extended, combining the ease of use of well-established notations, notably those based on characteristics, and those based on Finite-state Machines (FSM), with the computational power and expressiveness of the constraint programming approach. The paper briefly presents the results of the preliminary evaluation, which assesses the expressiveness, scalability, and domain independence of the SCT language.
Benefits of Purely Online Journals and the Challenges

There are numerous well-established parameters to judge and evaluate the standard of a medical journal like quality of its contents and geographic distribution of manuscripts, it attracts for publication, indexation and coverage in important indexes and databases like Medline, Web of Sciences by Clarivate known for its Impact Factor (IF), PubMed Central, Scopus etc., journal visibility and readership, timely regular publication.Impact Factor is one of the criteria and not the only criteria, which should be used to judge the standard of a journal.However, too much importance being given to the Impact Factor by the regulatory bodies in Pakistan as well as by medical institutions, asking those doing PhD to publish their research work in Impact Factor journals has created a crisis like situation not only for the researchers but also made the life of the IF journal editors miserable.They are under tremendous pressure to accommodate more and more papers by the authors anxious for early publication to meet certain deadlines for the completion of their research project and award of degrees while the editors on their part are faced with a dilemma due to human resource and financial resource constraints.In an environment where political stability remains in short supply most of the time, law and order situation is unpredictable, not to forget the frequent breakdown of electricity and inefficient internet service, it is not possible to either increase the frequency of publications or plan some other measures which all call for additional investment.Finding trained human resource and then retaining those remains a constant problem.

Multi-Person Face Recognition Across Variations in Pose Using Deep Learning Techniques

Face detection and recognition is a popular issue in computer vision. It has many applications and problems such as pose variation, illumination variation, occlusions which are yet to be solved. Face detection only means detecting whether or not the face of person in the image given. Recognition of the face is the authentication in which the individual is known or recognized. This work has two phases, namely: In the first step, using Viola-Jones-masters algorithm, this work detected the face of the person and using this algorithm we will extract the haar features. We present a face detection and recognition algorithm in the proposed framework that will be accurate in computational terms for large datasets and speed. In the recognition stage, by using the deep learning face embedding process, we will recognize the person by comparing the face with the current novel created dataset of our system and LFW.

Challenges and Prospects for Cloud-Based Enterprise Systems in Tradition-Focused Cultures: A Design Thinking Case Study

Cloud-based enterprise systems, a growing segment in the global market for enterprise IT solutions, have met with strong resistance in traditions-focused cultures such as Japan’s. Low cloud concept utilization has caused difficulties during the coronavirus pandemic, as remote work was not always technically possible due to the limitations of on-premises solutions. Our work applied Design Thinking methodology to form a foundation stone upon which cloud providers may build a Cloud Mindset in Japan and similar markets. This article considers both the endogenous agility that SaaS can engender with organisations and the exogenous possibilities that it brings about in terms of connections with other organisations. It describes the case study and covers six phases, from understanding the problem to testing a prototype of the solution. The research aims to act as a practical inquiry into the appliance of Design Thinking methodology in the new, challenging field of building Cloud Mindsets in multi-language environments. Consideration of the cultural semiosphere forms a necessary element of the research. The scientific achievement of this work is to make useful modifications to the classical methodology in this field. The practical value of the work lies in its applications for cloud providers in countries with similar cultural aspects to Japan.
Attitudes of Young Dhatki Speakers towards Their L1 and Its Maintenance

This qualitative study explores the attitudes that speakers of Dhatki as a first language (L1) hold towards their mother tongue and their willingness to maintain the language in the future.The study also touches areas such as young speakers of Dhatki as L1 and their interest in learning different languages.The research data was collected through the semi-structured interviews based on multiple sessions.Grounded theory has been used as the approach to execute the study.The data was analyzed and turned into codes and themes.The participants do not think Dhatki has any instrumental value because it is not used in schools and other official domains around the country.Although Dhatki's instrumental value is low, the children hold positive attitudes towards maintenance of their L1.The children do not think that Dhatki should be used in the school as the medium of instruction because it is not used in the rest of the country and it could cause a hindrance in their learning and job seeking.The children have integrative motivation to continue learning and maintaining Dhatki because it is a part of who they are.They want to be able to stay in contact with their family and close ones to share their world experiences.However there are a few children who are not interested in maintaining Dhatki as their L1 and transfer it to the next generation because Dhatki has a low instrumental value.The situation of Dhatki can be improved by introducing it as a subject in the school and organizing programs to celebrate the Dhatki language and culture.To stop language loss due to language shift and language death, it is important to improve a language's instrumental value.
PETROLOGICAL CHARACTERIZATION AND REMOTE SENSING-BASED MAPPING OF WADI EL GHUZA AREA, NORTH EASTERN DESERT, EGYPT

Wadi El Ghuza area is located north of Safaga-Qena asphaltic Road and covers an area of about 450 km 2 , dominated by different Late Neoproterozoic plutonic and volcanic complexes.The area comprises metavolcanics, serpentinites, metagabbros, older Granitoids, volcanosedimentary succession, felsitic intrusions, younger Granites, and post granitic dykes, respectively from the oldest to youngest rock units.Six consecutive sections were measured for the first time on the Wadi El Ghuza volcanosedimentary successions and exhibited stratigraphic intercalation between the Dokhan-type volcanics and the Hammamat sedimentary rocks.A new detailed geological map of the study area was prepared using remote sensing techniques and conventional and unconventional fieldwork.The false color composite 157 in RGB derived from ETM+ data and the composite 421 in RGB derived from ASTER principal component analysis technique discriminated and distinguished the lithology of different rock units in Wadi El Ghuza area.Geochemical studies of the Late Neoproterozoic units including the Dokhan volcanics and the Younger Granites indicate that they are high-K calc-alkaline affinity and were produced from A-type magmas in post-collisional settings.The studied A-type magma has been assumed to be generated by melting of crustal rocks of tonalite composition.
Image Encryption System Based On Chaotic System And DNA Computing

The misuse and arbitrary tampering of digital images by third parties pose a threat to the security and privacy of human subjects, requiring the development of good encryption techniques to meet the security needs of digital images. In this paper, we focus on the image encryption algorithm based on the combination of hyper chaotic system and DNA operation, which divides the digital image into three two-dimensional matrices by R, G and B channels, encrypts the image in blocks, and the chaotic sequence generated by the chaotic system determines the DNA coding, decoding and operation of each image block in the encryption process. The number of chaotic systems in the algorithm is increased and the encryption process is optimized to address the problems of low key space and inability to resist cropping attacks. The simulation results show that the improved encryption algorithm can resist the exhaustive key attack, the correlation of adjacent elements of the encrypted image is greatly reduced, and the encrypted image is resistant to cropping.
Linguistic Personality: Requirements to a Modern Textbook

This research focuses on the development of a comprehensive personality of a student, a future professional, who is able to complete tasks in the specific time and in the target situation in all parts of the world. For bringing up such a personality, it is necessary to design the teaching materials in such a way that they reflect modern requirements in the profession. It is very important to immerse a student in the language every minute for developing a lexico-grammatical model of linguistic competence on the basis of communication in vocationally-oriented language. Therefore, new initiatives of modern world apply requirements to the construction of teaching materials with the aim of forming linguistic personality, who is thinking, reading, writing and communicating in the international language. To work out such a textbook is not simple. The main requirement for this textbook is maintaining student’s interest in professional language environment. This environment must be created within university campuses and it is necessary to work out the complex of exercises so that a student could speak English on the professional topics of the specific field of study. Suggested teaching materials were researched and tested in the student’s environment and made the base of survey. The results show high knowledge of students and their motivation to study foreign languages for special purposes, personality development and self- evolution.
