Existential, Instrumental and Cyber Spaces as Ontological Modi of Human Being

Context and relevance of the research: the task of developing a general theoretical basis and methodology of ontological problems of interaction and interrelation of the Internet space and the physical world comes forward with the formation of the virtual computer environment determined both by the presence of a human being in computer network and presence of computer network in the life world of the human being. Virtual reality, even in its current state, is already widely recognized and described in academic sources. There are prospects of its application in medicine, education, professional training, space, military, art, automotive industry, shipbuilding, trade, leisure, consulting assistance to population, administration, and other spheres of management. According to academic forecasts, intensive, large-scale, multidirectional development of virtual computer environment will continue in the 21st century. The purpose of the study is to carry out a systematic analysis of the concepts: existential space, instrumental space and cyberspace in their interrelationship and interaction; to propose the author’s definition of existential space as a methodological construction for the study of its ontological modi: instrumental space and cyberspace; to define the ontological characteristics of instrumental space and cyberspace, their common features (connection) and distinction; to reveal features of existential immersion of a person into virtual computer reality – the process of emotional perception of existence in the information field – an artificially created world of ‘people and things,’ as well as subjective-personal effects accompanying this process. The methodology used: M. Heidegger’s Dasein analytics, D. Ihde’s instrumental realism, systems-based approach, comparative analysis. Key findings: the creation of cyberspace and computer virtual reality has unveiled a new stage in the formation of existential experience and project as a system of information technology and socio-psychological competencies. There is a necessity in the system-based elaboration of conceptual and categorical apparatus. The researcher will use it to describe the ontological modi of both existing and a new (computer virtual) reality and their interconnection.
Zooming in on agentivity: Experimental studies of DO-clefts in German

Abstract Despite the importance of the agent role for language grammar and processing, its definition and features are still controversially discussed in the literature on semantic roles. Moreover, diagnostic tests to dissociate agentive from non-agentive roles are typically applied with qualitative introspection data. We investigated whether quantitative acceptability ratings obtained with a well-established agentivity test, the DO-cleft, provide evidence for the feature-based prototype account of (Dowty, David R. 1991. Thematic proto-roles and argument selction. Language 67(3). 547–619) postulating that agentivity increases with the number of agentive features that a role subsumes. We used four different intransitive verb classes in German and collected acceptability judgements from non-expert native speakers of German. Our results show that sentence acceptability increases linearly with the number of agentive features and, hence, agentivity. Moreover, our findings confirm that sentience belongs to the group of proto-agent features. In summary, this suggests that a multidimensional account including a specific mechanism for role prototypicality (feature accumulation) successfully captures gradient acceptability clines. Quantitative acceptability estimates are a meaningful addition to linguistic theorizing.
Pruning and repopulating a lexical taxonomy: experiments in Spanish, English and French

Abstract In this paper we present the problem of a noisy lexical taxonomy and suggest two tasks as potential remedies. The first task is to identify and eliminate incorrect hypernymy links, and the second is to repopulate the taxonomy with new relations. The first task consists of revising the entire taxonomy and returning a Boolean for each assertion of hypernymy between two nouns (e.g. brie is a kind of cheese ). The second task consists of recursively producing a chain of hypernyms for a given noun, until the most general node in the taxonomy is reached (e.g. brie → cheese → food → etc.). In order to achieve these goals, we implemented a hybrid hypernym-detection algorithm that incorporates various intuitions, such as syntagmatic, paradigmatic and morphological association measures as well as lexical patterns. We evaluate these algorithms individually and collectively and report findings in Spanish, English and French.
PERSEPSI PESERTA DIDIK TERHADAP PEMBELAJARAN BERBASIS DARING

Online learning is a solution in the era of the COVID-19 pandemic. However, of course, in the implementation, there must be many difficulties for both teachers and students. This study aims to describe students' perceptions of online learning in Lampung Province. Samples were randomly selected using the Slovin Method with a population of Senior High School students in Lampung Province. 400 students from more than 25 schools were chosen for this study. The sample is given a perception questionnaire that has been tested for validity and reliability which is made on Google Form. Based on the research results, it can be concluded that students get good support from various parties in implementing online learning. However, the majority of students experienced problems related to signals during online learning. Many students also have not been able to master the learning application well so that it will affect the learning process. In addition, students stated that they had difficulty communicating with the teacher and preferred to have face-to-face discussions and students had difficulty understanding the material if it only came from books.
A Robust Authentication Algorithm for Medical Images Based on Fractal Brownian Model and Visual Cryptography

In this paper, we aimed to discuss the security authentication requirements of medical images in the medical network, and a security authentication method is designed based on fractal and visual cryptography. Based on the discrete fractal Brownian random field model, the gray-level statistical information and spatial structure information of medical images is fully mined. The gray distribution of medical images is expressed in the form of fractal features. By using the spatial data mining methods, the data of fractal structure space is analyzed, and by using the stability of the energy structure, the authentication features are formed. Using the visual cryptography (VC), the robustness of the authentication method is further enhanced. Through the centralized test of common medical images and the comparison analysis with existing methods, it is further verified that the method is effective against common attacks such as JPEG compression, scaling, rotation operation, clipping, added noise, filtering, and blurring.
A Query Optimization Method of Blockchain Electronic Transaction Based on Group Account

When an electronic transaction occurs, the blockchain system needs to find out whether the accounts of both parties of the transaction exist. However, However, in the existing blockchain account storage solution, account information query efficiency is low, which seriously affects query performance and user experience. To this end, we propose a blockchain-based electronic transaction lookup scheme for grouped accounts. We combine the characteristics of Merkle Patricia Tree, by constructing the Merkle Patricia Tree account storage structure GMPT (Group Merkel Partricia Tree), to reduce the time of querying the accounts of both parties of the transaction during electronic transactions. At the same time, in order to efficiently cluster accounts, we improved the RFM model and K-Means clustering algorithm, and gave out the RFM model based on blockchain accounts and the improved account grouping algorithm AccountGroup. Experiments show that the blockchain electronic transaction query scheme based on account grouping proposed in this paper can effectively reduce the time to query the accounts of both parties in electronic transactions, optimize the query efficiency, and improve the transaction speed of the blockchain system.
Automated SLA Negotiation in a Dynamic IoT Environment - A Metaheuristic Approach

In the Internet of Things (IoT), billions of physical devices, distributed over a large geographic area, provide a near real-time state of the world. By adopting a service-oriented paradigm, the capabilities of mobile or static devices can be abstracted as IoT services and delivered to users in a demand-driven way. In service environments, a particular service provisioning tends to be specified in a service level agreement (SLA), which can be further used to monitor and guarantee the quality of service (QoS). Automatic SLA negotiation can be used to resolve possible conflicts between trading parties, but existing SLA negotiation approaches do not consider the characteristics of an IoT environment. In this paper, we present an automated negotiation strategy for multi-round bilateral negotiation that caters for the level of dynamicity in an IoT environment. The negotiation strategy makes concessions based on the artificial bee colony (ABC) optimization algorithm. The simulation results demonstrate that our proposal provides a better balance between success rate and negotiation utility, compared to other approaches.
Analysis of Photodiode Sensing Devices in a Photonic Integrated Chip solution for Quantum Computing

From encryption to machine learning, the interest in quantum technologies is growing by the day.Many big companies are pushing the research and trying to develop a variety of techniques to achieve the so-called "quantum supremacy."Among all, there is one which is simpler to build an integrated system with: photonics.In this study, we illustrate the characterization for sensing elements of a prototype photonic integrated chip (PIC) where the photonic layer and the detector layer are homogeneously integrated.We fabricated in our facility a testing chip with silicon photodiodes as output devices.After the characterization discussed in this work, such detectors will be used as fully integrated sensing elements for a more advanced chip featuring thermistors as phase shifters in a multiple Mach-Zehnder Interferometers architecture.
A K-means Bat Optimisation Algorithm Applied to the Set Covering Problem

Optimization at the industry level is a fundamental area since it allows reducing costs and being more sustainable. Many of these problems are combinatorial and NP-hard. On the other hand, swarm intelligence metaheuristics have been able to successfully address these types of problems, however, many of these techniques work in searching continuous spaces. In this article, we explore a general binarization mechanism of continuous metaheuristics based on the k-means technique. In particular, we applied the k-means technique to the bat algorithm with the aim of addressing the set covering problem (SCP). Experiments were designed to evaluate the contribution of the k-means technique in the binarization process. In addition, we verify the effectiveness of our algorithm through reference instances. The results indicate that the k-means binary bat algorithm (KBBA) gets adequate results when evaluated with a combinatorial problem like SCP.
Preparation methods and progress of experiments of quantum microwave

Based on the characteristics of superposition, entanglement, non-locality and non-clonality of quantum mechanics, quantum information science can break through the physical limits of classical information and open up a new information processing function different from classical electromagnetic application methods. Due to the advantages of high-energy single photon in practical applications, the research and application of optical quantum information technology dominates the development of current quantum information technology. However, the free-space transmission of light waves is greatly affected by weather conditions and atmospheric particles. Comparing with other wave bands, classical microwave signal shows good penetration ability when transmitting in free space. By introducing quantum mechanics, microwave signal also exhibits non-classical merits. As quantum microwave signal inherits both classical transmission performance and quantum non-classical features, it can be utilized as a significant signal source for diverse applications in microwave domain, such as quantum communication, quantum navigation and quantum radar, which are based on quantum technologies in large scale and dynamic free space transmission. There are three main experimental platforms on which quantum microwave is studied and produced. They are cavity quantum electrodynamics(C-QED) system, circuit quantum electrodynamics(c-QED) system, and cavity electro-opto-mechanical(EOM) system, involving with several nonlinear effects such as Kerr effect, Casimir effect, three-wave mixing, etc. In this paper, the setups of these platforms and the preparation principles are introduced. Meanwhile, the preparation principles and methods of microwave single photon, entangled microwave photons, squeezed microwave fields and entangled microwave fields are summarized and analyzed in detail from three aspects. The present status of experimental progress in the relevant fields are summarized and listed as well. Besides, key problems in the application of quantum navigation in free space utilizing quantum microwave are probed. Among them, the most pressing ones are preparation ability, decoherence in transmission and detection of entangled quantum microwave signals, which are also discussed and analyzed in this paper. Finally, we look forward to the future development of quantum microwave technology. It mainly consists of manufacturing microwave detectors with high efficiency, designing thermal photon filters, and developing suitable antennas. We hope that this study can provide useful reference for scholars who are engaged in or interested in research related to quantum microwave technologies.
Hyperentanglement concentration of nonlocal two-photon six-qubit systems via the cross-Kerr nonlinearity

We present an efficient hyperentanglement concentration protocol (hyper-ECP) for two-photon six-qubit systems in nonlocal partially hyperentangled Bell states with unknown parameters. In our scheme, we use two identical partially hyperentangled states which are simultaneously entangled in polarization and two different longitudinal momentum degrees of freedom (DOFs) to distill the maximally hyperentangled Bell state. The quantum nondemolition detectors based on the cross-Kerr nonlinearity are used to realize the parity checks of two-photon systems in three DOFs. The hyper-ECP can extract all the useful entanglement source, and the success probability can reach the theory limit with the help of iteration. All these advantages make our hyper-ECP useful in long-distance quantum communication in the future.
A proposed lightweight image encryption using ChaCha with hyperchaotic maps

Image encryption plays a pivotal rule in enhancing telecommunications media. Since Privacy is necessary in our daily life in many areas, the personal image will be encrypted when it sent it over the Internet to the recipient to maintain privacy issue. In this paper, the image is encrypted using ChaCha symmetric stream cipher with Hyperchaotic Map. Due to the sensitivity characteristics of initial conditions, pseudo randomness chaotic maps and control parameters in chaotic, Hyperchaotic maps is use, higher security is obtained via using initial seed number, variance of parameters, and unpredictable direction of chaotic. The suggested lightweight image encryption has confirmed robustness contra brute force attacks by providing a massive key space. Furthermore, the suggested lightweight image encryption is eligible to defense from statistical cracking, insecurity of image based on criteria's histogram correlation and entropy.
A Risk Perception Indicator to Evaluate the Migration of Government Legacy Systems to the Cloud

Cloud computing is a new platform that offers potential cost reduction and reduced infrastructure management effort. Organizations are migrating legacy systems to the cloud to take advantage of its benefits. In this work, the authors propose a risk perception indicator (RPI) to bring objectivity to the decision about which systems could be migrated and about their migration order. The main goal of this article is to validate the RPI in the government domain. Through a case study with three government legacy systems and an experimental analysis based on a survey with 248 IT government employees, the RPI was evaluated and adjusted. The adjustments were made based on survey's results and appear to improve its accuracy and representativeness. The results showed that the use of the reference model and the risk perception indicator is sound and important regarding government legacy systems migration to the cloud.
IskiOS: Intra-kernel Isolation and Security using Memory Protection Keys

Operating system (OS) kernels such as Windows, Linux, and MacOS are vulnerable to control-flow hijacking. Defenses exist, but many require efficient intra-address space isolation. For example, execute-only memory requires read protection of code segments, and shadow stacks require write protection from buffer overwrites. Intel's Protection Keys for Userspace (PKU) could, in principle, provide the intra-kernel isolation needed to implement such features, but, when used as designed, it applies only to user-mode application code. This paper presents an unconventional approach to memory protection, allowing PKU to be used within the OS kernel on existing Intel hardware, replacing the traditional user/kernel isolation mechanism and, simultaneously, enabling efficient intra-kernel isolation. We call the resulting mechanism Protection Keys for Kernelspace (PKK). To demonstrate its utility and efficiency, we present a system we call IskiOS: a Linux variant featuring execute-only memory (XOM) and the first-ever race-free shadow stacks for x86-64. Experiments with the LMBench kernel microbenchmarks display an average overhead of about 11% for PKK and no additional overhead for XOM. IskiOS's shadow stacks bring the total to 22%. For full applications, experiments with the system benchmarks of the Phoronix test suite display negligible overhead for PKK and XOM, and less than 5% for shadow stacks.

A hierarchical reasoning graph neural network for the automatic scoring of answer transcriptions in video job interviews

We address the task of automatically scoring the competency of candidates based on textual features, from the automatic speech recognition transcriptions in the asynchronous video job interviews. The key challenge is to construct the dependency relations and semantic level interaction over each question–answer (QA) pair. However, most recent studies focus on the representation of questions and answers, but ignore the dependency information and interaction between them, which is critical for QA evaluation. In this work, we propose a hierarchical reasoning graph neural network for the automatic assessment of question–answer pairs. Specifically, we construct a sentence-level relational graph neural network to capture the dependency information of sentences in or between the question and the answer. Based on these graphs, we employ a semantic-level reasoning graph attention network to model the interaction states of the current QA session. Finally, we propose a gated recurrent unit encoder to represent the temporal question–answer pairs for the final prediction. Empirical results on CHNAT (a real-world dataset) validate that our proposed model significantly outperforms matching-based benchmark models. Ablation studies and experimental results with 10 random seeds also show the effectiveness and stability of our models.
The project solution of the refrigeration machine scheme with the heat utilization of condensation

Abstract Refrigeration machines are widely used in various industries to produce artificial cold. In the process of maintaining low temperatures, the refrigeration machine generates a lot of heat to compress a refrigerant, which is not used in the future, and during the condensation it is released into the environment in the form of water vapor. This negatively affects to the environment because of increasing the concentration of greenhouse gases in the atmosphere. And the use of chlorine-containing refrigerants causes the destruction of the ozone layer. To reduce environmental damage, it is necessary to increase the energy efficiency of refrigeration machines and develop schemes that allow the use of low-grade heat, which is released during operation. In the work, a scheme of a refrigeration machine was developed, which allows utilizing the heat of condensation, using it for various consumers of thermal energy, therefore allowing to reduce emissions of harmful substances into the Earth’s atmosphere and increase technological capabilities of cooling.
CYBERSPACE AND VIRTUAL REALITY AS CHARACTERISTICS OF THE INFORMATION SOCIETY

The article attempts to comprehend cyberspace in its relationship with virtual reality. It is shown that due to cyberspace there are rapid changes in public consciousness and moods of people, accelerating social transformations in society. Changes in time boundaries, the emergence of timeless concepts in the information age are also associated with the latest reproductive technologies of the human body, including cloning, which is proposed as virtualization deformations of the space-time continuum in the information age, and as radical transformations of its understanding. The ever-changing cyberspace is the result of a virtualization process. The most impressive achievement of the new information technology is the opportunity for a person who has entered the virtual world, not only to observe and experience, but also to act independently. The question is stated about space-time characteristics of virtual reality and the ways of their ontological substantiation is raised. The main spatio-temporal properties of virtual reality created by cyberspace are highlighted. It is substantiated that virtual reality, formed by new information technologies, contributed to the creation of a network society, and the existence of cyberspace is its basis, which affects all spheres of public life.
