The Status of Textile-Based Dry EEG Electrodes
Authors: Tseghai Granch Berhe , Malengier Benny , Fante Kinde Anlay , Langenhove Lieva Van
Published: January 2020

Electroencephalogram (EEG) is the biopotential recording of electrical signals generated by brain activity. It is useful for monitoring sleep quality and alertness, clinical applications, diagnosis, and treatment of patients with epilepsy, disease of Parkinson and other neurological disorders, as well as continuous monitoring of tiredness/alertness in the field. We provide a review of textile-based EEG. Most of the developed textile-based EEGs remain on shelves only as published research results due to a limitation of flexibility, stickability, and washability, although the respective authors of the works reported that signals were obtained comparable to standard EEG. In addition, nearly all published works were not quantitatively compared and contrasted with conventional wet electrodes to prove feasibility for the actual application. This scenario would probably continue to give a publication credit, but does not add to the growth of the specific field, unless otherwise new integration approaches and new conductive polymer composites are evolved to make the application of textile-based EEG happen for bio-potential monitoring.
An overview of techniques for multifold enhancement in solubility of poorly soluble drugs
Authors: Ansari Mohammad Javed
Published: January 2020

Poor water solubility of newly discovered compounds has become the most common challenge in the drug development process. Indeed, poor solubility is considered as the root cause of failure of drug during drug development phases. Moreover, it has also been reported to be the main reason for bioavailability issues such as poor, inconsistent, incomplete and highly variable bioavailability of the marketed products. As per an estimate, approximately 90% of drug molecules suffer with poor water solubility at early stage and approximately 40% of the marketed drugs have bioavailability problems mainly due to poor water solubility. Solubility enhancement of the newly discovered compounds is primary research area for the pharmaceutical industries and research institutions. The conventional techniques to improve aqueous solubility of drugs employ salt formation, prodrug formation, co-crystallization, complexation, amorphous solid dispersion and use of co-solvent, surfactants or hydrotropic agents. Current advancement in the science and technology has enabled the use of relatively new techniques under the umbrella of nanotechnology. These include the development of nanocrystals, nanosuspensions, nanoemulsions, microemulsions, liposomes and nanoparticles to enhance the solubility. This review focuses on the conventional and current approaches of multifold enhancement in the solubility of poorly soluble marketed drugs, including newly discovered compounds.
The Role of Transformational School Leadership in Promoting Teacher Commitment: An Antecedent for Sustainable Development in South Africa
Authors: Khumalo Shuti Steph
Published: January 2020

Promoting sustainable development is top on the agenda of many national governments. The provision of quality primary education is key in pursuing this agenda and relies heavily of committed teachers. This article explores the potential contribution of transformational leadership practices of primary school principals in promoting teacher commitment. It is argued that primary school principals who exhibit the transformational leadership feature of commitment motivate teachers towards commitment and thus contribute towards sustainable development. This study was quantitative in nature and out of the hundred and fifty teachers sampled, only ninety-five responded to the questionnaires. Drawing from the theory of transformational leadership and the findings from the Limpopo Province education district case study, it can be concluded that primary school principals promote the culture of commitment and therefore a foundation for sustainable development is laid.

Authors: Pinho Maria Inês , Fernandes Dárida , Serrão Carla , Mascarenhas Daniela
Published: January 2020

Today’s society has valued entrepreneurship in various sectors of personal and professional life, but the school seems to forget this reality. Aware of this fact, the Portuguese Ministry of Education has created a program, from early childhood education to basic and secondary education, to develop the concept of social entrepreneurship in schools. The Porto Polytechnic Higher School of Education, as an educator of teachers and teachers of the First and Second cycle of Basic Education, joined the European UKIDS project to integrate this theme in the initial and continuous teacher training. In this article we will analyze the data obtained from a UKIDS Portuguese Partner School in the context of continuing teacher education and present some conclusions. The qualitative methodology used allowed us to conclude that the UKIDS project enhanced the valorization of individual capacities, such as creativity, self-confidence, the power of argumentation, as well as the construction of social competences, in interpersonal and group relationships, which are crucial in the formation of a child’s personality in the basic school learning process.
Entrepreneurship Education in a Democratic Perspective
Authors: Tiemensma Britt Due , Rasmussen Connie Stendal
Published: January 2020

Entrepreneurship Education often emphasizes the practical applications of competencies. This article aims to collect findings on entrepreneurship education linked to democratic formation in primary education as experienced by teacher students. Based on a model from the Danish Foundation for Entrepreneurship and theories on democratic formation and active citizenship, the authors analyze what entrepreneurship and democratic formation have in common. Entrepreneurship education will also be linked to education for sustainable development. By following a group of teacher students in two different cases, the authors discuss how a potential synergy is visible, when the teacher students learn by reading, discussing and solving concrete tasks connected to social entrepreneurship education. The teacher students’ personal attitudes and understanding of authentic practical experiences turns out to be important to their learning from entrepreneurial education tasks. The structural organization of teacher education is a challenge to the organization of teaching entrepreneurship education.

Authors: Akyar Begum Canaslan , Sapsaglam Özkan
Published: January 2020

Today’s children are born into a digital world and are exposed to various electronic devices and digital contents both in the home environment and other environments since the first years of life. Children, who are a natural recipient of the environment in which they live, are exposed to the effects of the digital world at different levels and reflect these effects in different ways. The purpose of the reported study is to investigate if preschoolers’ daily media usage habits affects their drawings. This study is planned according to the case study design of qualitative research methods. The study was conducted with 15 preschoolers and their parents. There were nine boys and six girls in the study. The preschoolers’ drawings and their parents’ interview data were analyzed by using the descriptive analyzing method. The study result shows that there are differences between boys and girls media usage habits. Boys spend more time with media tools than girls. Additionally, boys are exposed to more inappropriate content because of their preferences. The analysis of their drawings revealed that boys are more affected than girls from media contents since boys’ drawings include more characters from media than girls. It can thus be suggested that media tools might be harmful when they are used in a developmentally inappropriate way, and excessive media tool usage has negative impact on children. Therefore, the reported study recommends that parents and caregivers take some precautions to limit preschoolers from spending time with media tools and to control content of children’s activity.
Profit Reinvestment: Main Motives Supporting Financial Decisions
Authors: Pokorná Pavla , Šebestová Jarmila
Published: January 2020

Reinvestment decisions are based on basic the economic literacy of entrepreneurs because they do not want to affect future liquidity or development activities. The main goal of the article is to suggest a simple decision tree model to describe profit reinvestments in a general way based on results of a primary pilot study (128 interviews), where reinvestment behaviour is affected by specific factors like risk taking, competitive advantage or business experience. After that a decision-making tree is suggested to explain the process of reinvestment as determined by the manager.

Authors: Albalawi Abdulmajeed Saad , Naugton Shahnaz , Elayan Malek Bakheet , Sleimi Mohammad Tahseen
Published: January 2020

Background and Purpose: This article tested a structural model that examines the mediating role of organizational commitment on the link between perceived organizational support, perceived alternative job opportunities, and turnover intention, and the moderating role of job satisfaction on the proposed relationships.

Methodology: Using convenience sampling technique, a self-administered survey was conducted on a pool of Jordanian small and medium sized enterprises (SMEs). The obtained data (n=270) were analyzed with contemporary variance-based structural equation modelling (PLS-SEM) software SmartPLS v3.

Results: Findings revealed that organizational commitment mediates the association between perceived organizational support and turnover intention, perceived alternative job opportunities and turnover intention. In addition, job satisfaction did not moderate the associations between organizational support, perceived alternative job opportunity and organizational commitment.

Conclusion: The present study is among the first to show the mediating mechanism of organizational commitment on the link between perceived organizational support, perceived alternative job opportunity and turnover intention. Theoretical and practical implications are drawn, before pointing to potential future research directions that build on the evidence-based positions argued for in this study.
Counteracting domestic violence against elders in the professional practice of a nurse employed in the primary health care system
Authors: Kotarba Agnieszka , Maciaszek Adrianna , Borowiak Ewa
Published: January 2020

Aim. Assessment of preparation of a nurse – employee of the primary health care for providing preventative measures against domestic violence targeted at elders.

Material and methods. The material was collected in a group of 70 nurses – employees of the primary health care of a medical centre in Lodz. Inclusion criteria were: the respondent’s consent for the inclusion in the study and the position of a nurse of the primary health care system. The authors of the study used the diagnostic survey method, with the application of their own questionnaire. Obtained results were statistically analysed.

Results. In the nurses’ opinion, lack of knowledge of effective tools, which could be used to provide victims with help, considerably hampers implementation of preventive measures for counteracting domestic violence. A multivariate analysis revealed a relationship between the opinion of nurses on prevention of domestic violence against the elderly and their education, the number of years worked and individual beliefs.

Conclusions. Violence against elders is a growing global problem. Polish nurses are legally obliged to initiate interventions in order to counteract domestic violence. Nurses from the primary health care are not prepared to carry out prevention of violence against the elderly. There is a need to provide nurses employed in the primary health care with post-graduate training on counteracting domestic violence against the elderly.

Authors: Abdel daiem Mahmoud M. , Sánchez-Polo Manuel , Rashed Ahmed S. , Kamal Nehal , Said Noha
Published: January 2020

The adsorption of Diphenolic acid (DPA), 2,4-Dichlorophenoxyacetic acid (2,4-D), and 2-methyl-4-chlorophenoxyacetic acid (MCPA) were examined in aqueous solution using activated carbon rice straw. The rice straw was activated by using two reagents, zinc chloride and phosphoric acid and named as RSZ, RSP, respectively. The results showed that both carbons have a relatively high adsorption capacity. Concerning the adsorption kinetic, the second-order model has better fit than the first model to experimental data. The adsorption yield of both carbons increased in the order: DPA < 2,4-D < MCPA. The pore volume diffusion model satisfactorily fitted the experiment on both carbons. Furthermore, solution pH has a high influence on the adsorption capacity for both carbons. The adsorption mechanism of selected pollutants onto carbon samples has been controlled by dispersion interaction π-π electrons and electrostatic interaction, moreover, the contribution of pore volume diffusion is the controlling mechanism of the overall rate of adsorption.
The catalytic oxidation of toluene at low temperature over palladium nanoparticles supported on Alumina sphere catalysts: effects of Palladium precursors and preparation method
Authors: Pham Thien Huu , Than Ha An Quoc , Bui Ha Manh
Published: January 2020

In this study, 1 wt.% Pd/Al2O3 sphere catalysts were prepared using the wet-impregnation (WI) and deposition-precipitation (DP) method using palladium chloride and tetraamminepalladium (II) nitrate as salt precursors. All catalysts were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM) and Fourier-transform infrared (FTIR) spectroscopy. The catalytic activity in toluene oxidation under gas-phase conditions was measured. The obtained results showed that metal dispersion and catalytic activity were strongly dependent on the salt precursor and method of catalyst preparation. The use of tetraamminepalladium (II) nitrate as the precursor presented smaller particle size, an enhanced dispersion and higher specific surface area. Moreover, the catalyst prepared with this precursor also showed higher catalytic activity than that prepared with palladium chloride. At 1 wt.% Pd loading, complete oxidation of toluene was achieved at 250°C. However, there was only approximately 80–90% efficient at the same temperature when the catalyst was prepared with palladium chloride as the precursor.

Authors: Śpiewak Katarzyna , Czerski Grzegorz , Sopata Agnieszka
Published: January 2020

The aim of this study was to analyse the steam gasification process of ‘Janina’ coal with and without Na-, K- and Ca-catalysts. The catalysts were physically mixed with the coal due to the simplicity of this method, short time of execution and certainty that the amount of catalyst is exactly as the adopted one. The isothermal measurements were performed at 800, 900 and 950°C and a pressure of 1 MPa using thermovolumetric method. The obtained results enabled assessment of the effect of analysed catalysts on the process at various temperatures by determination of: i) carbon conversion degree; ii) yield and composition of the resulting gas; and iii) kinetics of formation reactions of main gas components – CO and H2. The addition of catalysts, as well as an increase in operating temperature, had a positive effect on the coal gasification process – reactions rates increased, and the process time was reduced.

Published: January 2020

The enthalpy of isopropanol adsorption on ZSM-5 (Zeolite Socony Mobil Framework Type MFI) was determined by the static adsorption method at the temperature range from 20°C to 100°C. Langmuir and Huttig models of equilibrium adsorption have been used to calculate the enthalpy of isopropanol adsorption at these conditions. Adsorption isotherms determined by the flow method at 20°C and 30°C have been also used in the calculations. The obtained values of isopropanol adsorption enthalpy were compared with the values of isopropanol evaporation enthalpy and with the results obtained from isopropanol and water desorption measurements with thermogravimetry and differential scanning calorimetry methods.

Herein, the photocatalytic degradation of the Congo Red (CR) and Crystal Violet (CV) dyes in an aqueous solution were discussed in the presence of an indium(III) oxide (In2O3) as optical catalyst efficiency. The caproate bidentate indium(III) precursor complex has been synthesized and well interpreted by elemental analysis, molar conductivity, Fourier transform infrared (FT-IR), UV-Vis, and thermogravimetric (TGA) with its differential thermogravimetric (DTG) studies. The microanalytical and spectroscopic assignments suggested that the associated of mononuclear complex with 1:3 molar ratio (M3+:ligand). Octahedral structure is speculated for this parent complex of the caproate anion, CH3(CH2)4COO− ligand. The In2O3 NPs with nanoscale range within 10–20 nm was synthesized by a simple, low cost and eco-friendly method using indium(III) caproate complex. Indium oxide nanoparticles were formed after calcination of precursor in static air at 600°C for 3 hrs. The structural, grain size, morphological and decolorization efficiency of the synthesized NPs were characterized using the FT-IR, X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX) and transmission electron microscopy (TEM) analyses. It was worthy mentioned that the prepared In2O3 NPs showed a good photodegradation properties against CR and CV organic dyes during 90 min.
Prediction of the fixed-bed reactor behavior for biotransformation with parallel enzyme deactivation using dispersion model: A case study on hydrogen peroxide decomposition by commercial catalase
Authors: Grubecki Ireneusz , Kazimierska-Drobny Katarzyna
Published: January 2020

The problems of process costs and pollution of residual waters in the textile industry require increasing attention due to the new ecological regulations and also those resulting from an economic point of view. Hence, the behavior of non-isothermal fixed-bed reactor applied for hydrogen peroxide decomposition by immobilized Terminox Ultra catalase attached onto the outer surface of glass beads was studied to determine the operational conditions at which hydrogen peroxide decomposition is most effectively. A dispersion model for bioreactor applied in this work, and verified experimentally, took into account the coupled mass and heat balances as well as the rate equation for parallel enzyme deactivation. The effect of feed temperature, feed flow rate, feed hydrogen peroxide concentration, and diffusional resistances were analysed. In the calculations the global effectiveness factor based on the external mass-transfer model developed previously was employed to properly predict the real bioreactor behavior.
Computation on Encrypted Data using Dataflow Authentication
Authors: Fischer Andreas , Fuhry Benny , Kerschbaum Florian , Bodden Eric
Published: January 2020

Encrypting data before sending it to the cloud protects it against attackers, but requires the cloud to compute on encrypted data. Trusted modules, such as SGX enclaves, promise to provide a secure environment in which data can be decrypted and then processed. However, vulnerabilities in the executed program, which becomes part of the trusted code base (TCB), give attackers ample opportunity to execute arbitrary code inside the enclave. This code can modify the dataflow of the program and leak secrets via SGX side-channels. Since any larger code base is rife with vulnerabilities, it is not a good idea to outsource entire programs to SGX enclaves. A secure alternative relying solely on cryptography would be fully homomorphic encryption. However, due to its high computational complexity it is unlikely to be adopted in the near future. Researchers have made several proposals for transforming programs to perform encrypted computations on less powerful encryption schemes. Yet current approaches do not support programs making control-flow decisions based on encrypted data.

We introduce the concept of dataflow authentication (DFAuth) to enable such programs. DFAuth prevents an adversary from arbitrarily deviating from the dataflow of a program. Our technique hence offers protections against the side-channel attacks described above. We implemented DFAuth using a novel authenticated homomorphic encryption scheme, a Java bytecode-tobytecode compiler producing fully executable programs, and an SGX enclave running a small and program-independent TCB. We applied DFAuth to an existing neural network that performs machine learning on sensitive medical data. The transformation yields a neural network with encrypted weights, which can be evaluated on encrypted inputs in 0.86 s.
Inferring Tracker-Advertiser Relationships in the Online Advertising Ecosystem using Header Bidding
Authors: Cook John , Nithyanand Rishab , Shafiq Zubair
Published: January 2020

Online advertising relies on trackers and data brokers to show targeted ads to users. To improve targeting, different entities in the intricately interwoven online advertising and tracking ecosystems are incentivized to share information with each other through client-side or server-side mechanisms. Inferring data sharing between entities, especially when it happens at the server-side, is an important and challenging research problem. In this paper, we introduce Kashf: a novel method to infer data sharing relationships between advertisers and trackers by studying how an advertiser’s bidding behavior changes as we manipulate the presence of trackers. We operationalize this insight by training an interpretable machine learning model that uses the presence of trackers as features to predict the bidding behavior of an advertiser. By analyzing the machine learning model, we can infer relationships between advertisers and trackers irrespective of whether data sharing occurs at the client-side or the server-side. We are able to identify several server-side data sharing relationships that are validated externally but are not detected by client-side cookie syncing.
Emotional and Practical Considerations Towards the Adoption and Abandonment of VPNs as a Privacy-Enhancing Technology
Authors: Namara Moses , Wilkinson Daricia , Caine Kelly , Knijnenburg Bart P.
Published: January 2020

Virtual Private Networks (VPNs) can help people protect their privacy. Despite this, VPNs are not widely used among the public. In this survey study about the adoption and usage of VPNs, we investigate people’s motivation to use VPNs and the barriers they encounter in adopting them. Using data from 90 technologically savvy participants, we find that while nearly all (98%; 88) of the participants have knowledge about what VPNs are, less than half (42%; 37) have ever used VPNs primarily as a privacy-enhancing technology. Of these, 18% (7) abandoned using VPNs while 81% (30) continue to use them to protect their privacy online. In a qualitative analysis of survey responses, we find that people who adopt and continue to use VPNs for privacy purposes are primarily motivated by emotional considerations, including the strong desire to protect their privacy online, wide fear of surveillance and data tracking not only from Internet service providers (ISPs) but also governments and Internet corporations such as Facebook and Google. In contrast, people who are mainly motivated by practical considerations are more likely to abandon VPNs, especially once their practical need no longer exists. These people cite their access to alternative technologies and the effort required to use a VPN as reasons for abandonment. We discuss implications of these findings and provide suggestions on how to maximize adoption of privacy-enhancing technologies such as VPNs, focusing on how to align them with people’s interests and privacy risk evaluation.
Pets without PETs: on pet owners’ under-estimation of privacy concerns in pet wearables
Authors: van der Linden Dirk , Edwards Matthew , Hadar Irit , Zamansky Anna
Published: January 2020

We report on a mixed-method, comparative study investigating whether there is a difference between privacy concerns expressed about pet wearables as opposed to human wearables – and more importantly,why. We extracted the privacy concerns found in product reviews (N=8,038) of pet wearables (activity, location, and dual-function trackers), contrasting the (lack of) concerns and misuse to a curated set of reviews for similar human-oriented wearables (N=20,431). Our findings indicate that, while overall very few privacy concerns are expressed in product reviews, for pet wearables they are expressed even less, even though consumers use these devices in a manner which impacts both personal and bystander privacy. An additional survey of pet owners (N=201) eliciting what factors would cause them to not purchase (or stop using) pet wearables indicated comparably few privacy concerns, strengthening the representativeness of our findings. A thematic analysis reveals that the lack of privacy concerns may be explained by, among other factors, emotional drivers to purchase the device, and prioritization of (desired) functionality to support those emotional drivers over privacy requirements. Moreover, we found that pet wearables are used in different ways than originally intended, which raise novel privacy implications to be dealt with. We propose that in order to move towards more privacy-conscious use of pet wearables, a combination of understanding consumer rationale and behavior as well as ensuring data protection legislation is adequate to real-world use is needed.
The Best of Both Worlds: Mitigating Trade-offs Between Accuracy and User Burden in Capturing Mobile App Privacy Preferences
Authors: Smullen Daniel , Feng Yuanyuan , Aerin Zhang Shikun , Sadeh Norman
Published: January 2020

In today’s data-centric economy, data flows are increasingly diverse and complex. This is best exemplified by mobile apps, which are given access to an increasing number of sensitive APIs. Mobile operating systems have attempted to balance the introduction of sensitive APIs with a growing collection of permission settings, which users can grant or deny. The challenge is that the number of settings has become unmanageable. Yet research also shows that existing settings continue to fall short when it comes to accurately capturing people’s privacy preferences. An example is the inability to control mobile app permissions based on the purpose for which an app is requesting access to sensitive data. In short, while users are already overwhelmed, accurately capturing their privacy preferences would require the introduction of an even greater number of settings. A promising approach to mitigating this trade-off lies in using machine learning to generate setting recommendations or bundle some settings. This article is the first of its kind to offer a quantitative assessment of how machine learning can help mitigate this trade-off, focusing on mobile app permissions. Results suggest that it is indeed possible to more accurately capture people’s privacy preferences while also reducing user burden.

Authors: Akingboye Adedibu Sunny , Osazuwa Isaac Babatunde , Mohammed Muraina Zaid
Published: January 2020

Electrical resistivity tomography (ERT) was used for delineating significant subsurface hydrogeological features for sustainable groundwater development in Etioro-Akoko area, Southwestern Nigeria. This study was necessitated by challenges posed on groundwater supplies from wells and boreholes in Etioro-Akoko and the neighbouring fast growing towns and villages. Field data were acquired over the area with ABEM Lund Resistivity Imaging System and were subsequently processed and inverted through RES2DINVx64 software. Results showed four distinct subsurface layers: topsoil, weathered layer, fractured bedrock and fresh bedrock (basal unit). Localised bedrock depressions occasioned by fracturing and deep weathering of less stable bedrock minerals were delineated with resistivity and thickness values ranging from 50 to 650 Ωm and 12 to ---gt--- 25 m, respectively. The localised depressions mirrored uneven bedrock topography and served as the preferential groundwater storage and hydrogeological zones in the area. The two hydrogeological zones significant for groundwater development included overburden-dependent aquifers and fractured dependent bedrock aquifers. It was, therefore, concluded that groundwater storage potential was depended on hydrogeological zones particularly at major localised bedrock depressions where fractures and groundwater recharges/discharges were evident. Wells and boreholes were proposed at bedrock depressions with thickness value not less than 12 and ---gt--- 25 m, respectively, for enhanced groundwater sustainability and quality assurance in the area.
Physical Cavity of a Double Skin Facade as a Source of Pre-Heated Air in the Winter Season for the Heat Recovery Unit of a Facade
Authors: Bielek Boris , Klem Josip , Macák Marek
Published: January 2020

This paper deals with the use of pre-heated air in the winter season for the heat recovery unit of a facade. Heated air is transformed from solar radiation in the cavity of a double skin facade with a narrow space cavity. The height of a section is equal to one storey. With the help of mathematical modelling simulations (CFD tools), increases in temperature are quantified in the cavity of the double skin facade. The increase in temperature depends on the air flow and the intensity of the solar radiation. In conclusion, it summarizes the positive effect on heat recovery from the air exhaust to preheat a fresh supply of air from the double skin façade’s cavity. This approach can increase the efficiency of any heat recovery and reduce heat loss from the ventilation.
Utilization of Industrial Waste Products in the Production of Asphalt Concrete for Road Construction
Authors: Olugbenga Oyedepo J.
Published: January 2020

The utilization of industrial waste products to produce asphalt concrete for road construction was investigated. Aggregates were partially replaced with aluminum slag (AS) and crushed ceramic tiles (CCT) at 10%, 20%, 30%, 40%, and 50% by weight. Physical tests were performed on the aggregates, while a flash and fire point test as well as penetration tests were carried out on the bitumen. Similarly, Marshall stability tests were conducted on cylindrical specimens of the asphalt concrete. The average values of 18.88 and 30.69 obtained for the aggregate impact value (AIV) and aggregate crushing value (ACV) were satisfactory for road surfacing when compared with the specification. Marshall stability values of 10.84 KN, 4.27 KN, and 3.21 KN respectively were obtained with 30%, 20%, and 50% partial replacements with AS. The percentages were suitable for heavy, medium and light traffic when compared with the Marshall design criteria provided by the Asphalt Institute. The use of aluminum slag and crushed ceramic tile could reduce the large volume of industrial waste and the cost of pavement construction and maintenance.

Authors: Zinkevych Oksana , Savytskyi Mykola , Zinkevych Andrii
Published: January 2020

For low-rise buildings frame technologies using lightweight thin-wall steel constructions have become significantly widespread. The main influence on a building’s spatial rigidity under lateral forces is taken by shearwalls. The necessary stiffness can be accomplished by setting definite constructional parameters that are selected according to the design approach. The purposes of the work are to receive the dependencies of the influence of the constructional features on the stiffness of the shearwalls (using FEM models) and to set the value of the stiffness of the shearwall of any configuration by linking its parameters with the corresponding parameters of a standard shearwall through the established dependencies.

The received dependencies of the effect of the main constructional factors and design approach for the stiffness of shear-walls can be used to provide spatial rigidity. A simplified design approach for estimating the influence of the main constructional features of shearwalls on their rigidity has been developed.

Authors: Khan Mohd Jawad Ur Rehman , Awasthi Anjali
Published: January 2020

Prediction of greenhouse gas (GHG) emissions is important to minimise their negative impact on climate change and global warming. In this article, we propose new models based on data mining and supervised machine learning algorithms (regression and classification) for predicting GHG emissions arising from passenger and freight road transport in Canada. Four models are investigated, namely, artificial neural network multilayer perceptron, multiple linear regression, multinomial logistic regression and decision tree models. From the results, it was found that artificial neural network multilayer perceptron model showed better predictive performance over other models. Ensemble technique (Bagging & Boosting) was applied on the developed multilayer perceptron model, which significantly improved the model’s predictive performance.

The museum is a fun learning tool for the community. The Museum of Asian Art is one of the museums in Malaysia which was founded by Malaya University. The museum has three showroom floors and represents three civilizations; India, China and Islam. Every day the museum is very crowded by tourists to find information about artifact objects. Lots of artifacts stored in this museum include textiles, musical instruments, ceramics, masks, paintings, weapons and others. The museum itself is the right place to store and preserve ancient objects so they can still be seen and used as a source of learning and cultural preservation for the nation's next generation. This research takes the artifacts that are masks because the results of observations made by researchers, information about masks at the Museum of Asian Art Malaysia is very minimal compared to other artifacts, there are only name tags but there is no deeper information about the mask. So that it still cannot be used as a learning medium to the maximum. From this problem, researchers developed Nusantara Mask Heritage Malaysia (NUSMARI MALAYSIA) products based on Augmented Reality. The research method used is the development model into 4 steps: (1). Research and Information Collecting, (2). Planning, (3). Develop Preliminary Form Of Product, (4). Final Product Revision. The result of this development is a learning media application that can help tourists of all ages to more easily learn the mask of the Orang Asli Malaysia in the museum.

Cloud Computing is one of the technologies that continue to develop and progress in rapid adoption rates due to the various benefits and conveniences offered. Cloud Computing has four types of adoption models, one of which is a Private model and is widely adopted by users because it is safer and customizable. The high level of cloud computing adoption is an opportunity for criminals to use cloud computing in committing their crimes and requires handling digital forensics. However, each cloud model has different characteristics, so the investigative method used is also different. Then there is no specific guidance for investigating cloud computing. So it is necessary to analyse the investigation of private cloud computing that used OwnCloud from the server-side and develop the novel investigation framework based on SNI 27037: 2014. An analysis of investigations is performed to develop the novel investigation framework and to find out what evidence can be found based on the novel framework. The results of the research conducted can be a reference for investigators to conduct forensic investigations in cloud computing on the server-side and the novel investigation framework will become a reference to be used as a guide to the investigation on private cloud computing in the server-side.

Research subject.This is the first in the series of four articles, which aims to review existing provenance reconstruction tools.

Methods and materials. The data obtained during evaluation of different sandstone allothigenous components was used as a basis for analysis. The data was collected from the Upper Riphean Zilmerdak Formation Bir’yan Member and the Upper Vendian Bassa Formation (Southern Urals); the Upper Devonian Kodinka and Ust’kodinka formations (Middle Urals); the Lower Cretaceous Sortym Formation (Western Siberian sedimentary megabasin, Bolshekhetskaya depression).

Results. The sandstone composition patterns of the lithostratigraphic units under study allowed the most common provenance features to be established by means of comparing data obtained by various diagrams.

Conclusions. It is established that only the Kodinka, Ust’kodinka and Sortym sandstone compositions can be used as a source for rock reconstruction analysis, while the Bir’yan and Basa sandstone compositions have undergone massive transformations.
Understanding Aesthetic Experiences of Architectural Students in Vertical and Horizontal Campuses
Authors: Bostancı Seda , Akdağ Suzan Girginkaya
Published: January 2020

The typological features of university campus areas are shaped according to their locations in the city. Campuses in city centers carry great potentials for students’ cultural, intellectual and artistic activities, especially for those from faculty of architecture and design, with close relations to the city. The aim of this paper is to develop an approach for measuring architecture students’ aesthetic experience of vertical and horizontal campuses in relation to sense of place theory. Recently, emerging technologies in cognitive science, such as brain imaging techniques, activity maps, sensory maps, cognitive mapping and photo-projective method etc., have enabled advanced measurement of aesthetic experience. In this exploratory research, using ‘photo-projective method’, students will be asked to interpret and draw ‘cognitive maps’ of the places that they are happy to be (defined place) or to see (landscape) on the campus. Based on students’ impressions and experiences, it will be possible to compare aesthetic experience on vertical and horizontal campus. Thus, a comprehensive approach for improving campus design according to users’ aesthetic experiences and sense of place rather than building technology, law, development and finance-driven obligations will be introduced.
