Frequency Selective Auto-Encoder for Smart Meter Data Compression
Authors: Lee Jihoon , Yoon Seungwook , Hwang Euiseok
Published: February 2021

With the development of the internet of things (IoT), the power grid has become intelligent using massive IoT sensors, such as smart meters. Generally, installed smart meters can collect large amounts of data to improve grid visibility and situational awareness. However, the limited storage and communication capacities can restrain their infrastructure in the IoT environment. To alleviate these problems, efficient and various compression techniques are required. Deep learning-based compression techniques such as auto-encoders (AEs) have recently been deployed for this purpose. However, the compression performance of the existing models can be limited when the spectral properties of high-frequency sampled power data are widely varying over time. This paper proposes an AE compression model, based on a frequency selection method, which improves the reconstruction quality while maintaining the compression ratio (CR). For efficient data compression, the proposed method selectively applies customized compression models, depending on the spectral properties of the corresponding time windows. The framework of the proposed method involves two primary steps: (i) division of the power data into a series of time windows with specified spectral properties (high-frequency, medium-frequency, and low-frequency dominance) and (ii) separate training and selective application of the AE models, which prepares them for the power data compression that best suits the characteristics of each frequency. In simulations on the Dutch residential energy dataset, the frequency-selective AE model shows significantly higher reconstruction performance than the existing model with the same CR. In addition, the proposed model reduces the computational complexity involved in the analysis of the learning process.

Published: February 2021

Communicating in social and public environments are considered professional skills that can strongly influence career development. Therefore, it is important to proper train and evaluate students in this kind of abilities so that they can better interact in their professional relationships, during the resolution of problems, negotiations and conflict management. This is a complex problem as it involves corporal analysis and the assessment of aspects that until recently were almost impossible to quantitatively measure. Nowadays, a number of new technologies and sensors have being developed for the capture of different kinds of contextual and personal information, but these technologies were not yet fully integrated inside learning settings. In this context, this paper presents a framework to facilitate the analysis and detection of patterns of students in oral presentations. Four steps are proposed for the given framework: Data collection, Statistical Analysis, Clustering, and Sequential Pattern Mining. Data Collection step is responsible for the collection of students interactions during presentations and the arrangement of data for further analysis. Statistical Analysis provides a general understanding of the data collected by showing the differences and similarities of the presentations along the semester. The Clustering stage segments students into groups according to well-defined attributes helping to observe different corporal patterns of the students. Finally, Sequential Pattern Mining step complements the previous stages allowing the identification of sequential patterns of postures in the different groups. The framework was tested in a case study with data collected from 222 freshman students of Computer Engineering (CE) course at three different times during two different years. The analysis made it possible to segment the presenters into three distinct groups according to their corporal postures. The statistical analysis helped to assess how the postures of the students evolved throughout each year. The sequential pattern mining provided a complementary perspective for data evaluation and helped to observe the most frequent postural sequences of the students. Results show the framework could be used as a guidance to provide students automated feedback throughout their presentations and can serve as background information for future comparisons of students presentations from different undergraduate courses.
DANAE++: A Smart Approach for Denoising Underwater Attitude Estimation
Authors: Russo Paolo , Di Ciaccio Fabiana , Troisi Salvatore
Published: February 2021

One of the main issues for the navigation of underwater robots consists in accurate vehicle positioning, which heavily depends on the orientation estimation phase. The systems employed to this end are affected by different noise typologies, mainly related to the sensors and to the irregular noise of the underwater environment. Filtering algorithms can reduce their effect if opportunely configured, but this process usually requires fine techniques and time. This paper presents DANAE++, an improved denoising autoencoder based on DANAE (deep Denoising AutoeNcoder for Attitude Estimation), which is able to recover Kalman Filter (KF) IMU/AHRS orientation estimations from any kind of noise, independently of its nature. This deep learning-based architecture already proved to be robust and reliable, but in its enhanced implementation significant improvements are obtained in terms of both results and performance. In fact, DANAE++ is able to denoise the three angles describing the attitude at the same time, and that is verified also using the estimations provided by an extended KF. Further tests could make this method suitable for real-time applications in navigation tasks.
Distrust of Authorities: Experiences of Outcome and Processes of People Who Had Their Driving License Withdrawn Due to Visual Field Loss
Authors: Nyberg Jonna , Levin Lena , Larsson Katarina , Strandberg Thomas
Published: February 2021

Citizens’ trust of authorities is of general importance, as it can affect trust in society as a whole. The Swedish Transport Agency is a state administrative authority responsible for driving license withdrawal. If withdrawals are experienced as unfair by those affected, this might lead to decreased trust in the agency and in other actors involved. This study accordingly examines how the experiences of people who have had their driving license for a private car withdrawn due to visual field loss might affect their distrust of the authorities, as related to outcomes and processes. Follow-up interviews were conducted with nine people from a previous study. Content analysis revealed one overarching theme, struggling for justice within a system perceived as unfair, which comprised four identified categories: preparedness for and understanding of the withdrawn driving license (WDL); perceptions of assessment methods, reactions and actions regarding the decision, and perceptions of the authorities’ performance. In sum, the vision tests on which withdrawals are based were perceived as unfair, as they did not measure individual driving ability. Furthermore, rejections of appeals led to feelings of hopelessness. Distrust regarding outcomes and processes related to the withdrawals was also fueled by experiences of deficiencies regarding, for example, performance and information.

Published: February 2021

This paper proposes a set of five indicators to monitor the bioeconomy in Colombia and Antioquia, one of the main regions of the country. The proposed indicators encompass the dimensions of sustainability and emphasize the role of knowledge and scientific research as driving forces of the bioeconomy strategies. To estimate the contribution of the bioeconomy to value added, employment, and greenhouse gas emissions, an input–output analysis is carried out. In addition, text mining analysis techniques are implemented to identify the research groups with an agenda related to bioeconomy fields. Our results reveal an important slot to foster the growth of a sustainable bioeconomy that enables local economies to achieve inclusive growth.
A Structured Literature Review about the Role of Management Accountants in Sustainability Accounting and Reporting
Authors: Ascani Ilenia , Ciccola Roberta , Chiucchi Maria Serena
Published: February 2021

Management accountants have proven to be pivotal for introducing new forms of accounting and reporting in companies to support managers in their decision-making process. The purpose of this paper is to review the literature on the role management accountants play in sustainability accounting and reporting to understand how research is progressing, point out its focus, critique its developments, and finally, identify future research avenues. Results reveal that, to date, management accountants’ level of involvement is lower than that of non-accountants and that there is a consensus in academia and practice that a more significant involvement of management accountants is needed for promoting homogenization of sustainability accounting and reporting in companies and its more widespread diffusion and use among managers, thus embedding sustainability in corporate strategy and practices. Our findings show that more active involvement of management accountants depends, among other things, on their ability to broaden their competencies to include other domains of expertise and on the role of accounting education in improving their sustainability knowledge. Therefore, we call for more research on the competencies, skills, and roles that management accountants should play in order to promote the adoption and improvement of sustainability accounting and reporting.

Authors: Li Xiang , Xie Chaowu , Morrison Alastair M. , Nguyen Thi Hong Hai
Published: February 2021

Ethnic minority villages are a vital part of tourism in certain destinations, often attracting many domestic and international visitors to experience unique local cultures and authentic lifestyles. However, much of the relevant literature has not examined tourist motivations, perceptions, and attitudes regarding ethnic minority village tourism. This exploratory qualitative research analyzed user-generated blogs uploaded by people sharing their ethnic minority village experiences in Guizhou Province, China. ROST Content Mining6 software was employed to identify motivations, perceptions, and attitudes toward minority village tourism. The findings indicated that tourist experience included natural aesthetic, cultural aesthetic, service and interaction, and entertainment. The main motivation was to experience unique cultural activities. The strongest perceptions were of the local villagers, Miao and Dong family life, and tourism services and environments. Tourist attitudes were mostly positive. Suggestions for better satisfying tourist needs and improving experiences were derived from the data.
A Fuzzy-AHP Methodology for Planning the Risk Management of Natural Hazards in Surface Mining Projects
Authors: Spanidis Philip-Mark , Roumpos Christos , Pavloudakis Francis
Published: February 2021

Surface mining projects are vulnerable to natural hazards (earthquakes, floods, soil instabilities, and epidemic crises) which constitute the primary source of risks which affect the mining operations. In the framework of sustainable planning and development of such projects, the investigation of risk impacts is essential for taking the appropriate preventive measures before disastrous events appear in a mine. This paper proposes a methodology for the risk assessment of natural hazards in surface mining projects using the triangular Fuzzy Analytical Hierarchy Process (FAHP) for the determination of the probability of risk occurrence, combined with the Expected Value (EV) function, the Monte Carlo simulation, and the Program Evaluation Review Technique PERT method for making predictions of cost and time overruns. A case study of a hazardous event with impacts in the operations of a surface mine demonstrates the methodology as a flexible and low-cost tool for mining executives. This tool is useful in the planning stage of pre-disaster management projects in the mineral industry, considering mine sustainability views. The research work also investigates critical technical and economic aspects.
Sliding Mode Control and Geometrization Conjecture in Seismic Response
Authors: Munteanu Ligia , Dumitriu Dan , Brisan Cornel , Bara Mircea , Chiroiu Veturia , Nedelcu Nicoleta , Rugina Cristian
Published: February 2021

The purpose of this paper is to study the sliding mode control as a Ricci flow process in the context of a three-story building structure subjected to seismic waves. The stability conditions result from two Lyapunov functions, the first associated with slipping in a finite period of time and the second with convergence of trajectories to the desired state. Simulation results show that the Ricci flow control leads to minimization of the displacements of the floors.
Bootstrapped Newtonian Cosmology and the Cosmological Constant Problem
Authors: Casadio Roberto , Giusti Andrea
Published: February 2021

Bootstrapped Newtonian gravity was developed with the purpose of estimating the impact of quantum physics in the nonlinear regime of the gravitational interaction, akin to corpuscular models of black holes and inflation. In this work, we set the ground for extending the bootstrapped Newtonian picture to cosmological spaces. We further discuss how such models of quantum cosmology can lead to a natural solution to the cosmological constant problem.
Aerosolized Exposure to H5N1 Influenza Virus Causes Less Severe Disease Than Infection via Combined Intrabronchial, Oral, and Nasal Inoculation in Cynomolgus Macaques

Infection with highly pathogenic avian H5N1 influenza virus in humans often leads to severe respiratory disease with high mortality. Experimental infection in non-human primates can provide additional insight into disease pathogenesis. However, such a model should recapitulate the disease symptoms observed in humans, such as pneumonia and inflammatory cytokine response. While previous studies in macaques have demonstrated the occurrence of typical lesions in the lungs early after infection and a high level of immune activation, progression to severe disease and lethality were rarely observed. Here, we evaluated a routinely used combined route of infection via intra-bronchial, oral, and intra-nasal virus inoculation with aerosolized H5N1 exposure, with or without the regular collection of bronchoalveolar lavages early after infection. Both combined route and aerosol exposure resulted in similar levels of virus replication in nose and throat and similar levels of immune activation, cytokine, and chemokine release in the blood. However, while animals exposed to H5N1 by combined-route inoculation developed severe disease with high lethality, aerosolized exposure resulted in less lesions, as measured by consecutive computed tomography and less fever and lethal disease. In conclusion, not virus levels or immune activation, but route of infection determines fatal outcome for highly pathogenic avian H5N1 influenza infection.

Published: February 2021

This study aimed to evaluate the sealing quality of swine small intestine using different laparoscopic radiofrequency vessel sealing devices (two 5 mm: RFVS-1 and -2; one 10 mm: RFVS-3) and a harmonic scalpel (HS) compared to golden standard closure technique. The study was divided into two arms. In study arm 1: n = 50 swine intestinal loops (10 per group) were transected with each instrument and the loops in which the devices provided complete sealing, at the gross inspection, were tested for maximum burst pressure (BP) and histological evaluation and compared to an automatic linear stapler. After the BP tests, the devices that achieved significantly lower BP values were excluded from the second arm. The RFVS-1 and -3 provided statistically significant results and were used in study arm 2, to obtain full-thickness biopsies along the antimesenteric border of the loop and were compared with hand-sewn intestinal closure (n = 30; 10 per group). The biopsies were histologically evaluated for thermal injury and diagnostic features, and intestinal loops tested for BP. RFVS-3 achieved comparable results (69.78 ± 4.23 mmHg, interquartile range (IQR) 5.8) to stapler closing technique (71.09 ± 4.22 mmHg, IQR 4.38; p > 0.05), while the RFVS-1 resulted in significantly (p < 0.05) lower BP (45.28 ± 15.23 mmHg, IQR 24.95) but over the physiological range, conversely to RFVS-2 (20.16 ± 7.19 mmHg, IQR 12.02) and HS (not measurable). RFVS-3 resulted not significantly different (p > 0.05) (45.09 ± 8.75 mmHg, IQR 10.48) than Suture (35.71 ± 17.51 mmHg, IQR 23.77); RFVS-1 resulted significantly lower values (23.96 ± 10.63 mmHg, IQR 9.62; p < 0.05). All biopsies were judged diagnostic. Data confirmed that RFVS-1 and -3 devices provided suitable intestinal sealing, with BP pressures over the physiological range. Conversely, the HS and RFVS-2 should not be considered for intestinal sealing. RFVS devices could be employed to obtain small intestine stump closure or full-thickness biopsies. However, further studies should be performed in live animals to assess the role of the healing process.
L’hallucination, entre modification et pathologie de la conscience
Authors: Frerejouan Mathieu
Published: February 2021

The Hallucination, Between Alteration and Pathology of Consciousness. A state of consciousness is said to be “ altered” (ASC) when it appears qualitatively different from what the subject considers normal. However, this reference to normality is paradoxical, ASCs being frequently distinguished from pathological states of consciousness (PSC), themselves recognized as a deviation from the norm. Therefore, the study of ASCs faces a dilemma : to either arbitrarily reject PSCs from its field of study or extend a concept whose limits are already blurry. Our purpose will be to approach this problem through the study of hallucinations, which are regarded at the same time as a paradigmatic case of ASC and as a central object for psychopathology. We show that, in the case of hallucinations, not only the traditional criteria of “reversibility” and “insight” are insufficient to distinguish ASCs from PSCs, but even the idea of a difference between “altered” and “pathological” states must be questioned. Following the philosophy of Wittgenstein, we therefore try to prove that the description of a hallucination as “pathological” is linked to a “game-language” specific to psychiatry and, for this reason, is irrelevant regarding the study of ASCs.
Perspectives biogénétiques et neurophénoménologiques sur l’altération de la conscience
Authors: Winkelman Michael
Published: February 2021

Les altérations de la conscience manifestent une capacité énigmatique qui mobilise nos plus profondes capacités de connaissance. Leurs manifestations rituelles et spontanées partagent à travers toutes les cultures de mêmes propriétés, manifestant des similitudes dans le vol de l'âme, la possession et les expériences mystiques, qui reflètent les caractéristiques intrinsèques de la nature et de la biologie humaines. Le lien entre la nature phénoménale de ces expériences et les processus physiologiques associés, nous fournit un cadre biologique qui nous permet d'identifier les origines et les fonctions de ces expériences. L'altération de la conscience résulte de la stimulation des systèmes de neuromodulation de la sérotonine, de la dopamine et des endocannabinoïdes. Le vol de l'âme chamanique se définit en termes phénoménologiques, neurologiques et épistémologiques en impliquant des modalités spécifiques de représentation de l'environnement, de soi, de l'autre, des attachements et des émotions. Les approches biologiques de l'altération de la conscience fournissent des bases pour la caractérisation de ces expériences en termes de mode de conscience intégratif spécifié par des modèles cérébraux à ondes lentes, qui synchronisent le cortex frontal avec des décharges provenant de niveaux anciens du cerveau. Cette perspective place les altérations de la conscience dans un cadre théorique qui illustre leur rôle dans l'évolution cognitive, l'adaptation et la spécialisation épistémique de l'homme.
Conscience, rêves et inférence : le théâtre cartésien revisité
Authors: Hobson John Allan , Friston Karl J.
Published: February 2021

Consciousness, Dreams, and Inference : The Cartesian Theatre Revisited. This paper considers the Cartesian theatre as a metaphor for the virtual reality models that the brain uses to make inferences about the world. This treatment derives from our attempts to understand dreaming and waking consciousness in terms of free energy minimization. The idea here is that the Cartesian theatre is not observed by an internal (homuncular) audience but furnishes a theatre in which fictive narratives and fantasies can be rehearsed and tested against sensory evidence. We suppose the brain is driven by the imperative to infer the causes of its sensory samples ; in much the same way as scientists are compelled to test hypotheses about experimental data. This recapitulates Helmholtz’s notion of unconscious inference and Gregory’s treatment of perception as hypothesis testing. However, we take this further and consider the active on our virtual reality. The ensuing picture of consciousness (or active inference) resolves a number of seemingly hard problems in consciousness research and is internally consistent with current thinking in systems neuroscience and theoretical neurobiology. In this formalism, there is a dualism that distinguishes between the (conscious) process of inference and the (material) process that entails inference. This separation is reflected by the distinction between beliefs (probability distributions over hidden world states or res cogitans) and the physical brain states (sufficient statistics or res extensa) that encode them. This formal approach allows us to appeal to simple but fundamental theorems in information theory and statistical thermodynamics that dissolve some of the mysterious aspects of consciousness.
Modéliser les configurations d’états modifiés de conscience (CEMC) : vers une anthropologie interactionnelle de la conscience
Authors: Canna Maddalena
Published: February 2021

Comment rendre compte de la dimension interactionnelle des États Modifiés de Conscience ? Dans la première partie de cet article j’explore un cas ethnographique : la grisi siknis, une crise de transe hallucinatoire diffusée parmi les Miskitos et d’autres populations d’Amérique Centrale. Selon les théories locales, la crise de grisi siknis est un syndrome transmissible, qui affecte principalement les rassemblements de jeunes et d’adolescents. L’expérience de la crise est traumatique, car elle implique un ensemble de modifications physiologiques et métacognitives généralement non maîtrisées. À partir de l’exploration des interactions sociales constitutives de la grisi siknis, je soutiens la nécessité d’élaborer des modèles interactionnels de Configurations d’États Modifés de Conscience (CEMC). Pour ce faire, je propose une articulation entre modèles prédictifs-inférentiels (bayésiens) et analyses pragmatiques de l’action. Enfin, j’avance l’esquisse d’une anthropologie de la conscience apte à explorer les sociétés en tant que champs d’influences psycho-physiologiques intersubjectives. J’évalue la portée théorique de ce programme et ses possibles applications thérapeutiques.
Expériences « hors du corps » : un voyage « en esprit » à la rencontre d’un autre de soi
Authors: Baud Sébastien
Published: February 2021

Out-of-Body Experiences. A Soul’s Journey to Meet Another Self. In this paper, I would like to write an anthropology of altered states of consciousness, namely to question of the dynamic and content – which makes subjectivity – of such experiences. To do this, I review narratives and perceptions of the body during spiritual experiences (ritual or spontaneous) such as : 1. possession and psychedelic trips, at Peru, Cusco region (in urban areas) and among Awajun, a Jivaro linguistic family ; 2. Out-ofbody experiences from “ modernity” European. These experiences are characterized by the lucid feeling to see in a distance vision their body and its surroundings, which range from what I call another self or a subjectivity which feels itself as such. There is not denial and derealization, but recognition of the body, unlike psychopathological experiences in which the absence creates delusions. As consequence, the experiences are conceived as true by people. Furthermore, they allow a relationship characterized by a verbal exchange -possession or spiritual encounter – and the acquisition of knowledge that can be used for therapeutic purposes or witchcraft, divination and initiation.
Langage et réplication
Authors: Roulland Daniel
Published: February 2021

Cet article souhaite montrer que les causes des oppositions grammaticales (du type this / that en anglais) sont profondes et tiennent au caractère systémique du langage (Douay & Roulland, 2014), qui se réplique et fonctionne sur un processus de dédoublement et une unité relationnelle. Les oppositions sont les manifestations de cette distinction qui détermine les deux rôles interlocutifs émetteur et récepteur, le signe matérialisant le tiers relationnel qui les associe. Ce processus est illustré à la fin de l’article avec le micro-système de still, yet et already en anglais. Auparavant, il est nécessaire de revenir sur la problématique saussurienne de la forme et de la substance, et sur l’autopoïèse et le languaging, puis sur le modèle de l’énaction. Cela permet de voir que le problème de l’interaction linguistique repose sur la ligne de partage entre la structure interne de l’unité observée, et son comportement externe. Si c’est le système lui-même, et non une entité externe, qui est son propre observateur, alors le dédoublement systémique peut être défini comme une auto-distinction du système. Dans ce cas, le tiers relationnel est le système lui-même, c’est-à-dire le signe linguistique et le langage. Ce type de solution concerne directement la question interactionnelle qui pose de nombreux problèmes dans le cadre de l’autopoïèse.
Making Sense of Languaging as a Consensual Domain of Interactions: Didactic implications
Authors: Kravchenko Alexander
Published: February 2021

Comprendre la langue comme un domaine consensuel d''interactions : Implications didactiques. Dans cet article, certaines fausses idées concernant la langue et la communication sont signalées comme faisant partie du mythe du langage rationnel et l’accent est mis sur la nécessité de la naturalisation de la langue. La discussion porte sur l’importance cruciale du concept de la mise en langage en tant que domaine consensuel d’interaction, d’où provient la fonction signifiante des signes linguistiques. On fait valoir que la facilité d’acquisition du langage par les enfants provient de l’indexicalité intrinsèque des signes linguistiques – leur enracinement perceptuel dans le domaine consensuel de premier ordre. En tant qu’indices, les signes linguistiques dirigent la compréhension humaine concernant les divers aspects du contexte des interactions dialogiques. Ce travail démontre comment le fait de considérer la grammaire comme un mécanisme sémiotique enraciné sur le plan perceptif, qui est à la base de la mise en langage, facilite l’acquisition instruite d’une langue étrangère, ce qui permet de briser le mythe de la complexité des langues.

Conceptualising the Commercial Determinants of Health Using a Power Lens: A Review and Synthesis of Existing Frameworks
Authors: Wood Benjamin , Baker Phillip , Sacks Gary
Published: February 2021

Background: There is increasing recognition that power imbalances that favour corporations, especially those active in unhealthy commodity industries, over other actors are central to the ways in which corporations influence population health. However, existing frameworks for analysing corporate strategies and practices that impact on health do not incorporate concepts of power in consistent ways. This paper aimed to review the ways in which corporate power has been incorporated into such frameworks, and to propose a revised framing of the commercial determinants of health (CDoH) that makes concepts of power explicit. Methods: We conducted a narrative review of frameworks that identify corporate strategies and practices and explain how these influence population health. Content analysis was conducted to identify explicit references to different qualities of power – its origins, nature, and manifestations. Results: Twenty-two frameworks were identified, five of which used theories of power. A wide range of contexts that shape, and are shaped by corporate power were discussed, as were a diversity of corporate, social and ecological outcomes. A variety of material and ideational sources of power was also covered. We proposed an integrated ‘Corporate Power and Health’ framework to inform analysis of the CDoH, organised around key questions on power set out by Foucault. The proposed framework draws from a number of well-established corporate power theories and synthesises key features of existing CDoH frameworks. Conclusion: Public health advocates, researchers and policy-makers would likely be better placed to understand and address the CDoH by engaging with theories of power to a greater extent, and by explicitly incorporating concepts of corporate power in analyses of how the deployment of corporate strategies and practices influence population health.

Published: February 2021

Distribution Transformer is used for providing electricity to the consumers. It provides the required voltage to the consumers by stepping down the voltage in distribution side. So, monitoring the distribution transformer is the unapproachable task for the electricity department to monitor those transformers regularly. This paper provides a solution for reducing the man power in monitoring of the transformer in online by analyzing various parameters like voltage, current, temperature, oil level by using various sensors. The sensors are used to monitoring the various parameters in transformer with the help of microcontroller. The IOT server is used to receive the data of operation and abnormal condition of transformer, and these data are stored in the computer server with help of particular web address.

Published: February 2021

This paper focuses on the design and construction of an optimization charging system for Li–Po batteries by means of tracked solar panels. Thus, the implementation of a complete energy management system applied to a robotic exploration vehicle is put forward. The proposed system was tested on the VANTER robotic platform — an autonomous unmanned exploration vehicle specialized in recognition. The interest of this robotic system lies in the design concept, based on a smart host microcontroller. On this basis, our proposal makes a twofold significant contribution. On the one hand, it presents the construction of a solar tracking mechanism aimed at increasing the rover’s power regardless of its mobility. On the other hand, it proposes an alternative design of power system performance based on a pack of two batteries. The aim is completing the process of charging a battery independently while the other battery provides all the energy consumed by the robotic vehicle.

Cloud computing is third party administrative control so our data is outsourced it gives rise to security concerns.security is one of the important aspect of any technology. Therefore high security measures are required to protect our data. In this paper, we propose Detaching and Reproducting of Data in a cloud for excellent performance and security that collectively approaches security issues and data sharing protectively. In this methodology, we divide the file into fragments and replicated over cloud nodes. Files are fragmented and shuffled like (1-2,2-3,3-4.4-1)in sequential order and stored in multiple servers. Moreover nodes sharing fragments are separated with certain distance by using T-colouring graph to prohibit an attacker by guessing the location of fragments. This methodology does not rely on traditional cryptography techniques.

The experimental values of ultrasonic velocity, density and viscosity have been measured for the ternary liquid mixtures containing 2-Nitroanisole and 1-Pentanol in n-Hexane at 303,308 and 313K. To calculate various acoustical parameters like adiabatic compressibility, free volume, internal pressure, acoustical impedance, adsorption co-efficient and molecular interaction parameters have been computed using the experimental data. The linearity of variation in ultrasonic velocity and other parameters are due to the molecular interaction between donor acceptor molecules in liquid-liquid mixture. The various molecular interactions like dipole-dipole, dipole-induced dipole, induced-induced dipole have been discussed for the liquid mixture containing 2-Nitroanisone, 1-Pentanol in n-Hexane at different temperatures and concentration.
A Wavelet Based Differential Algorithm for Busbar Protection

Published: February 2021

Busbar protection is an essential component in power system design, protecting the most important system node for network stability and security. When faults occurs on busbar itself, it takes much time to isolate the bus from source which may cause much damage in the bus system. Faults in power system are classified as internal and external faults. Faults within the zone are termed as internal faults whereas, the faults outside the Zone are called as external faults. Ideally, a relay looking after the protection of a zone should operate only for internal faults. It should restrain from operating for external faults or through faults. In this paper the busbar protection using differential protection scheme has been investigated for internal and external faults. An algorithm has been developed to improve the selectivity of the relay and the same has been tested in IEEE9 bus system for internal and external faults. Separation of De-noised signal from fault signal is made using wavelet transform so that the nature of fault occurs on the system can be identified. In this study Daubechies 4 at level 3 is used to separate original signal and de-noised signal. The entire simulation has been done using MATLAB R2017a.

The smart city consists not only the suffocated facilities but also it should consist of a smart solid waste management system. The huge generation of solid waste and shortage of land for dumping results in search of best schemes.  Collection, transportation, and disposal of solid waste is a huge concern and also a very challenging task. Proper tools like IoT should be employed to integrate these works smoothly and efficiently. IoT consists of sensors which help in indicating the waste levels and collection routes to the server, from which the waste was collected in a quick and efficient manner. IoT contributes in all stages of waste management, which results in saving of time and money.
An Experimental Study on Pervious Concrete

Pervious concrete is a type of concrete with high porosity. It is used for concrete flatworks application that allows the water to pass through it, thereby reducing the runoff from a site and allowing ground water recharge. The high porosity is attained by highly interconnected voids content. Pervious concrete has water to cementicious material ratio of 0.36. The mixture is composed of cementicious materials, coarse aggregates and water with no fine aggregates. In this paper works porous concrete with fly ash as a blended material is tested for strength and permeability for assessing the adaptability of fly ash as a substitute material to cement. The percentage of fly ash is varied from 10% and 20%. Various tests like compressive strength, tensile strength and water permeability are done on the specimens and results are discussed.

The use of plastics in the current busy world has increased multiple times in the past few years. Many forthcoming industries and enterprises (business companies and organizations) produce more varieties of plastic. The inappropriate way of disposing these plastics will result these detrimental compounds to pollute and degrade the environment by getting mixed with it. The intermolecular bonds that constitute plastics are designed in such a way that it can neither get corroded nor decomposed. In order to succeed this issue we have to find an effective way to dispose plastics. In this project we have used recycled plastic wastes to construct paver blocks. This material also has few advantages like they are extremely durable and hard to reject (them last for a long period of time), it doesn’t have rusting properties and are non-soluble in water. These properties together makes plastic highly durable. The main aim of this project is to reduce the dependency level of construction materials on natural resources which are on verge of getting exhausted and also to diminish the environmental degradation caused by the utilization of plastics. We also used IOT sensors in this project to detect the temperature and alert the users regarding the condition of plastics used inside the paver blocks. This will allow the users to take proper measures and repair it accordingly.

This paper presents the results of an experimental investigation of the compressive strength of concrete cubes containing termite mound soil. The specimens were cast using M20 grade of concrete. Two mix ratios for replacement of sand and cement are of 1:1.7:2.7 and 1:1.5:2.5 (cement: sand: aggregate) with water- cement ratio of 0.45 and varying combination of termite mound soil in equal amount ranging from 30% and 40% replacing fine aggregate (sand) and cement from 10%,15%,20% were used. A total of 27 cubes, 18 cylinders and 6 beams were cast by replacing fine aggregate, specimens were cured in water for 7,14 and 28 days. The test results showed that the compressive strength of the concrete cubes increases with age and decreases with increasing percentage replacement of cement and increases with increasing the replacement of sand with termite mound soil cured in water. The study concluded that termite mound cement concrete is adequate to use for construction purposes in natural environment.
