Proposta per una valutazione automatica della completeness dei metadati nel contesto delle biblioteche digitali
Authors: Lorenzini Matteo , Rospocher Marco , Tonelli Sara
Published: May 2021

Grazie all’utilizzo dei metadati è possibile accedere ad un vasto numero di risorse rese disponibili attraverso archivi e biblioteche digitali. Normalmente i metadati sono strutturati secondo uno schema standardizzato e garantiscono l’interoperabilità e l’identificazione di un oggetto digitale facilitando l’accesso a determinati tipi di risorse. Tuttavia, una bassa qualità dei metadati e delle informazioni che questi rendono disponibili, come ad esempio la mancanza di alcuni elementi rispetto allo schema di metadati utilizzato rappresenta tutt’ora un problema comune a molti repositories. In questo contributo presentiamo sia il nostro lavoro, allo stato attuale in corso, che ha come scopo la valutazione automatica della qualità dei metadati nelle digital libraries, che un’analisi preliminare sulla metadata completeness delle risorse presenti nell’aggregatore di metadati “CulturaItalia”.

Developing a Data-Driven Unsupervised Pattern Recognition Approach for Sensor Signal Anomaly Detection
Authors: Iranmehr Ensieh , Ferreira Ricardo , Böhnert Tim , Freitas Paulo
Published: May 2021

Coming up with a system for early detection of machine damages and failures is one of the important challenges in the industrial maintenance procedure to avoid additional costs and downtimes. To approach this goal, this paper uses the signal gathered by a sensing system which employed a spintropic sensor to measure the magnetic field around the machine which somehow shows the machine's behaviour. Using this signal and focusing on analysing and processing the signal, this paper develops a data-driven method to recognize signal patterns and subsequently detects anomalies. A challenging task that we succeeded to overcome in this paper is recognizing relevant signal patterns without having any prior knowledge. An algorithm designed for this task is therefore completely unsupervised which makes it consistent and suitable to apply it for the signals gathered for other types of machines. Using both frequency and time domain information, the proposed algorithm, which utilizes signal processing and machine learning techniques, is able to efficiently identify relevant signal patterns. Clustering results on the real data gathered by the aforementioned sensor have shown the high accuracy of 99.38% in recognizing patterns. Furthermore, an anomaly score measure is used and according to its distribution, anomalies are detected appropriately.
A Survey of Multipath TCP Scheduling Schemes: Open Challenges and Potential Enablers
Authors: Asiri Mohammed Yahya
Published: May 2021

Today, mobile devices like smartphones are supported with various wireless radio interfaces including cellular (3G/4G/LTE) and Wi-Fi (IEEE 802.11) [42]. The legacy devices can only communicate with only one interface. The Transmission Control Protocol, or TCP, has a limitation inability to change connection settings without breaking the connection. In this paper, we explain how multi-path TCP (MPTCP) protocol has been proposed to solve TCP single-interface limitation and provides a huge improvement on application performance by using multiple paths transparently (auto path changing). We discuss the last mile, which is the final networking segment that carried all network traffic. Indeed, the available bandwidth in last-mile link can effectively harm the network throughput as it limits the amount of transmitted data. We found that the quality of the last mile networks significantly determines the reliability and quality of the carrying network. We believe MPTCP can provide a convenient solution for the last mile problem. We provide a holistic view of the challenges and potential enablers in details.
Immersive virtual reality methods in cognitive neuroscience and neuropsychology: Meeting the criteria of the National Academy of Neuropsychology and American Academy of Clinical Neuropsychology
Authors: Kourtesis Panagiotis , E. MacPherson Sarah
Published: May 2021

Clinical tools involving immersive virtual reality (VR) may bring several advantages to cognitive neuroscience and neuropsychology. However, there are some technical and methodological pitfalls. The American Academy of Clinical Neuropsychology (AACN) and the National Academy of Neuropsychology (NAN) raised 8 key issues pertaining to Computerized Neuropsychological Assessment Devices. These issues pertain to: (1) the safety and effectivity; (2) the identity of the end-user; (3) the technical hardware and software features; (4) privacy and data security; (5) the psychometric properties; (6) examinee issues; (7) the use of reporting services; and (8) the reliability of the responses and results. The VR Everyday Assessment Lab (VR-EAL) is the first immersive VR neuropsychological battery with enhanced ecological validity for the assessment of everyday cognitive functions by offering a pleasant testing experience without inducing cybersickness. The VR-EAL meets the criteria of the NAN and AACN, addresses the methodological pitfalls, and brings advantages for neuropsychological testing. However, there are still shortcomings of the VR-EAL, which should be addressed. Future iterations should strive to improve the embodiment illusion in VR-EAL and the creation of an open access VR software library should be attempted. The discussed studies demonstrate the utility of VR methods in cognitive neuroscience and neuropsychology.

Inserted in this context of the pandemic caused by Covid-19 and food insecurity, it has been important to reflect on the rethinking of “new forms” of territorialized commercialization, distribution and consumption, which may involve the participation of communities, in the search for quick and more agile solutions. The objective of the study was to verify the conditions in which two innovation ecosystems were structured and operated in Mato Grosso do Sul, which emerged at the encouragement of the Banco do Brasil Foundation during the Covid-19 pandemic, working through short chains, in the search for urgent solutions to supply healthy food to the most vulnerable populations. The object of this investigation was the ecosystems articulated by the Central dos Trabalhadores/as da Economia Solidáriain Campo Grande and the Associação dos Produtores Orgânicos de Mato Grosso do Sul (APOMS) in Glória de Dourados, with an area of activity in several surrounding municipalities, involving suppliers and the beneficiary population. The research, of a descriptive and exploratory type, was based on an initial bibliographic review, followed by the collection of information from bibliographic and documentary sources and also the application of semi-structured interviews to those responsible for the entities that articulate each ecosystem. It was possible to verify that the structure and functioning of the two innovation ecosystems responded in great part, not only to the context of the circumstances and territories in which they were manifested, but also to the nature of public incentive policies. In addition to boosting the local economy, they favored the social inclusion of vulnerable populations and, even if in a palliative way, they guaranteed food security for numerous families in the territories where they demonstrated an innovative way of building social markets in Mato Grosso do Sul.

Authors: Hase Sandra Liliana , Linares A. , Kachuk L. , Pérez Navarro O. , Miño Valdés Juan Esteban
Published: May 2021

Los snacks de mandioca son una alternativa atrayente para los productores locales y para la población celíaca ya que no contienen gluten. La fritura por inmersión profunda resulta adecuada para la preparación de snacks de textura y sabor únicos. Los snacks son elaborados a partir de puré de mandioca, cuyo componente mayoritario es el almidón parcialmente gelatinizado. Esto puede favorecer a la formación de una corteza que disminuya la absorción de aceite. El objetivo de este trabajo fue determinar las condiciones adecuadas de temperatura y tipo de aceite para obtener un producto con bajo contenido de aceite y de agua. Se utilizó aceite de girasol (AG) y aceite de girasol de alto oleico (AGAO) a 150, 170 y 190 °C. Los resultados del estudio mostraron que los snacks perdieron peso durante la fritura aunque el volumen se conservó constante, debido a que el peso de agua perdida no fue reemplazado por el peso de aceite ganado. Se determinó que la ganancia de aceite fue alta a bajas temperaturas de fritura y la retención de agua fue alta a altas temperatura de fritura. Los snacks fritos en AG y AGAO a 170°C durante 180 segundos retuvieron la menor cantidad de agua y aceite.

Authors: Paziuk Vadym , Tokarchuk Oleksii , Tokarchuk Dina
Published: May 2021

Energy resources are of great importance for human life. Today, the intensive spread of renewable energy sources (RES) in the world is the result of complex political, social, economic and natural resources that have been developing over the past 40-50 years. These processes are associated with different levels and dynamics of economic development of states, an increase in energy consumption, an uneven distribution of natural resources, an increase in the world's population and climatic changes. The energy-saving way of economic development presupposes a significant reduction per unit of product consumption of fuel, electricity and heat at the final stage of their consumption; improvement of production, transportation, transformation and storage of energy resources; improving the structure of the energy balance in the direction of replacing scarce and expensive energy resources in it with cheap and affordable renewable energy sources. The growth of production and consumption is inextricably linked with the development of society, throughout its development it is fighting to increase its energy balance. The struggle for energy, for its source, for the discovery of new ways of transforming and using it is going on continuously and at an ever-increasing pace. The development of renewable energy sources in the world is associated with limited energy resources. From renewable energy sources, the use of solar energy, wind energy, water energy, environmental energy, geothermal energy, biomass energy has been obtained. Most of all in Ukraine, biomass energy is used to obtain thermal energy. Also, the use of environmental energy has been developed due to the introduction of heat pumps in heating systems of buildings, in the technological processes of drying and cooling.
RESEARCH OF VIBROREOLOGICAL MODELS OF LAYER OF BULK ENVIRONMENT
Authors: Polievoda Yurii , Volynets Yevhenii
Published: May 2021

Vibration mechanics and vibroreology play an important role in the new section of applied vibration theory formed in recent years - the theory of vibration processes and devices. This theory studies the patterns of excitation and vibration in different mechanical systems; it also includes the theory of machines in which vibration is used to achieve useful goals.
Based on the considered models, it was possible to describe the chaotic motion of the bulk medium layer over the vibrating plane. Such movements, well known for liquids, have indeed been observed in the case of a bulk medium, which serves as another confirmation of the possibility of modeling slow motions of a bulk medium during vibration in the form of viscous fluid motions (of course, with the above caveats and additions).
When studying the described simplest models, motion (including we are interested in slow motion) can be found by directly using the solution of the problem of vibrotransportation of the body (particles). The value of this approach is determined, however, by the possibility of its application for an approximate solution in more complex cases. In the study of slow motions of bodies interacting with both the forces of dry friction and collisions, these interactions can be modeled by the forces of viscous friction, taking into account the driving vibration force. This leads to the following vibroreological approach to modeling the behavior of the bulk medium in vibrating trays and vessels.
Of all the considered models, the most promising is the model of the behavior of the bulk medium under the influence of vibration in the form of a viscous medium.The described models can be used when considering a practically important task of vibration penetration into a free medium.

Random Access in IoT Using Naïve Bayes Classification
Authors: Almahjoub Alhusein , Qiu Dongyu
Published: May 2021

This paper deals with the random access procedure in next-generation networks and presents the solution to reduce total service time (TST) which is one of the most important performance metrics in current and future internet of things (IoT) based networks. The proposed solution focuses on the calculation of optimal transmission probability which maximizes the success probability and reduces TST. It uses the information of several idle preambles in every time slot, and based on it, it estimates the number of backlogged IoT devices using Naïve Bayes estimation which is a type of supervised learning in the machine learning domain. The estimation of backlogged devices is necessary since optimal transmission probability depends on it and the eNodeB does not have information about it. The simulations are carried out in MATLAB which verify that the proposed solution gives excellent performance.

Published: May 2021

Verbunddübelleisten stellen eine wirtschaftlich sowie technisch sinnvolle Alternative zu konventionellen Verbundmitteln, wie Kopfbolzendübeln, dar. Ihre Konkurrenzfähigkeit wird jedoch durch die Tatsache eingeschränkt, dass sie lediglich national und zeitlich befristet bauaufsichtlich zugelassen sind, wohingegen Regelungen für Kopfbolzendübel fest in den europäischen Normen verankert sind. Um auch die Verwendung von Verbunddübelleisten dauerhaft in die europäische Normung zu integrieren, sind die in den letzten Jahrzehnten auf nationaler und internationaler Ebene gesammelten Forschungsergebnisse zum Bauen mit Verbunddübelleisten zu kondensieren und in leistungsfähige Bemessungsregeln zu überführen. Dieser Beitrag präsentiert neue Untersuchungen zum Tragverhalten von Verbunddübelleisten im gerissenen Beton, unter Zug- und kombinierten Schub-Zug-Beanspruchungen sowie in oberflächennahen Einbaupositionen und beschreibt die Entwicklung eines konsistenten Bemessungskonzepts, das auf neuen und bereits vorhandenen Forschungsergebnissen basiert. Dieses Bemessungskonzept soll mittelfristig in den europäischen Normungsprozess eingebracht werden.

Published: May 2021

Mit diesem Beitrag wird ein aktuelles Urteil des Bundesverwaltungsgerichts vom 15.10.2020 aus juristischer und schalltechnischer Sicht kommentiert und kritisiert. Das Urteil hat weitreichende Konsequenzen für den Schallgutachter, der die Aufgabe hat, ein im Auftrag der DB Netz AG erstelltes Parteigutachten auf seine Richtigkeit hin zu überprüfen; kommt er zu einem anderen Ergebnis, so ist es (nahezu) unmöglich, das Gericht zu bewegen, durch ein von ihm in Auftrag gegebenes Gerichtsgutachten die erforderliche Klärung herbeizuführen. Auch sorgfältig vorbereitete Beweisanträge, die an offensichtliche Ungereimtheiten des angefochtenen Gutachtens anknüpfen, bleiben ohne jede Resonanz. Darauf muss sich der kritisierende Gutachter einstellen. Das kritisierte Gutachten begründet den Verdacht, dass die von den Prozessparteien vorgelegten Gutachten vom Bundesverwaltungsgericht unterschiedlich (ungleich) behandelt werden, je nachdem ob das Gutachten von der Antragstellerin eines Planfeststellungsverfahren (hier der DB Netz AG) oder von den von den Folgen des Antrags betroffenen Bürgern vorgelegt werden. Das „DB-Gutachten“ trägt die unerschütterliche Vermutung der Richtigkeit.

Ein halbempirisches Modell zur Berechnung der Explosionsgrenzen und der Sauerstoffgrenzkonzentration
Authors: Vogel Hans-Herbert
Published: May 2021

Zur quantitativen Beurteilung der Explosionsgefahren brennbarer Gasgemische dienen die sicherheitstechnischen Kenngrößen Zündtemperatur, Mindestzündenergie, Explosionsgrenzen, Sauerstoffgrenzkonzentration und Löschabstand. Die untere und obere Explosionsgrenze, welche von der Temperatur und dem Druck abhängen, geben die Brenngaskonzentrationen an, bei denen mit Luft gerade keine Explosion mehr stattfindet. Basierend auf dem Programm Cantera von Goodwin und einer geeigneten Reaktionskinetik wird ein Modell vorgestellt, das die Explosionsgrenzen von Methan, Ethan und Propan abschätzt. Die Vorhersagegenauigkeit dieses Modells für die obere Explosionsgrenze des Methans ist mit einer mittleren relativen Abweichung von 2,9 % als gut zu bezeichnen, für die des Ethans mit 8,4 % Abweichung als befriedigend und für die des Propans mit 12,6 % als ausreichend. Die untere Explosionsgrenze wird für alle drei Brenngase befriedigend bis gut wiedergegeben.

Nicht nur bei Neubau, auch bei Umbau und Modernisierung ist die Baugenehmigung abhängig von einer Entwässerungsplanung gemäß den aktuellen Technischen Regeln und Verordnungen. Das Entkoppeln von Schmutz- und Regenwasser gehört ebenso dazu wie das Behandeln des Regenwassers vor der Versickerung. Sind oberflächige Sickermulden nicht zulässig oder fehlt der Platz dafür, kommen unterirdische Alternativen (wie z. B. Versickerungsrigolen mit Vorbehandlung des Regenwassers) zum Einsatz. Befahrbar und einfach in der Wartung sind Anlagen aus Beton, die traditionell von Tiefbauunternehmen versetzt werden.
A quartzite inclusion in the R~nne Granite - the fist Danish
sediment?
Authors: Friis Henrik
Published: May 2021

The original thin sections from a quartzite inclusion in the RØnne Granite described by Karen Callisen in 1934 have been reexarnined. They appear to represent a sandstone, which has been strongly recrystallized in the granite, but which
has retained some evidence of the original fabric. It is concluded that the sandstone was either still porous or was carbonate cemented when it was included in
the granitic magma. Part of the intergranular space has been filled by granitic
minerals, mainly microcline, but carbonate minerals are important. Some of the
recrystallized quartz grains contain many mineral inclusions as well as liquidlgas
inclusions. It is suggested that future studies of sedimentary rocks included in the
basement rocks of Bornholm may give important knowledge on intmsion depth
and temperature of the granites.

Safety concerns require the frequently check for leaks in gas pipelines. Also, in coal mines the type gases permeating from the ground need to be monitored. Triboelectric nanogenerators (TENGs) can be applied for gas sensing without external power supply. In this paper, a two-dimensional model of a TENG was established, and a gas jet a rectangular cross section was added between two triboelectric materials. The TENG could generate distinguishable electrical signals according to the different types of gas and the different gas injection areas. This work contributes to the area of self-powered gas sensing.

Molecular phylogenies in the past decade have demonstrated that the described diversity of Cortinarius is still underestimated, especially outside continental and boreal ecoregions where the genus has been historically investigated. We tackled this issue by revisiting the so far unresolved subgenus Leprocybe, and focused on the largely unexplored Mediterranean hotspot of biodiversity. The sequencing and phylogenetic analysis of 161 vouchered collections from Austria, Cyprus, France, Germany, Italy and Spain, including 16 types, allowed for the delineation of 11 species in this lineage, three of them recognised as new to science and formally introduced as C. jimenezianus, C. selinolens and C. viridans spp. nov., respectively. Interestingly, the newly described species exhibit a strict Mediterranean distribution, and one of them is putatively endemic to the island of Cyprus, highlighting the remarkable potential of this neglected ecoregion to uncover further undescribed diversity of Cortinarius in the future. The present work also unveils 23 synonymies in this subgenus, as well as previously undetected crypticism within C. venetus. Next Generation Sequencing carried out on three old and contaminated holotypes, successfully decrypts their phylogenetic identity, including that of C. leproleptopus, finally settling the long-standing controversy over the taxonomic status of this species. A brief overview of each species in the subgenus is lastly provided and a key is proposed to facilitate the identification of presently known European taxa of Leprocybe in the field.

Published: May 2021

The academic performance of students in mathematics among public secondary schools in Nigeria has consistently been low over a period. There are many factors that may have contributed to this, however, the influence of classroom management practices on the academic performance have not been given much attention. Studies have shown that very little learning occurs in disorganized classrooms. This study therefore aims to explore how students’ academic performance in mathematics could be augmented through classroom management practices. Three research questions were raised, the main question is, how does classroom management practices enhance academic performance among students of public secondary schools in Nigeria? A descriptive research design was adopted using a total sample size N=250. The research instrument was a paper‐based questionnaire on a five‐point Likert scale administered face to face to randomly selected mathematics teachers from among 5 states in Nigeria, Mean and standard deviation were used to analyze the data and possible conclusions were drawn. The result among others shows that disciplined and well‐motivated classrooms have a significant impact on students’ academic performance in mathematics.

The Latvian SMEs are under pressure due to highly competitive foreign‐multinational‐ firms in the Latvian food market. The present paper consists of a pilot study which was aimed to reveal the factors influential for Latvian food SME development. This exploratory study was conducted on a deductive approach where the hypotheses were generated through literature, then those hypotheses can be either accepted or rejected by the survey data analysis. The authors have constructed an online mediated questionnaire based on scientific literature and expertise view. The survey was aimed at businesspeople & top‐level managers of Latvian food SMEsin the Riga region. The most influential factors for Latvian food SMEs' development were identified as “innovation” and “skills” which have high positive impacts on Latvian food SMEs' development. In the future, the most contributing areas (variable indicators) of these influential factors can be further explored with a higher sample size which is beneficial to identify potential innovative strategies related to innovation and skills.

This study examines the impact of retail services quality and selling behavior on customers’ satisfaction, trust, and store loyalty in case of high involvement products such as consumer electronics/home appliances in the context of Pakistan. The data was collected from 377 customers who completed the survey online. Respondents were particularly asked if they had any experience of buying such items recently and keeping in mind the purchase experience, rate the scale items accordingly. Factor analysis and multiple regression analysis were used for model testing. The study results show that store service quality and selling orientation strategy both have a significant impact on customer satisfaction, trust and store loyalty intentions. The study also involves the mediation analysis, satisfaction‐trust serving as mediator factor between two IVs (service quality and selling behaviors) and DV (store loyalty intentions). Results show that services quality and selling behaviour both have significant influence on store loyalty intentions. Further, satisfaction‐trust mediates the relationship between variables. The indirect path is significant which proves that satisfaction‐trust mediate the relationship between store attributes and consumer buying behaviour. The study has significant implications for multiple retail channels that can incorporate retail service quality and selling behaviour strategy (relational selling & consultative selling) to differentiate the retail brand services. Retailers of high involvement products category heavily relying on the selling skills and behaviour of salesperson/employee, can benefit from the study to implement retail brand positioning strategy.
