Augmented Robotics for Learners: A Case Study on Optics

In recent years, robots have been surfing on a trendy wave as standard devices for teaching programming. The tangibility of robotics platforms allows for collaborative and interactive learning. Moreover, with these robot platforms, we also observe the occurrence of a shift of visual attention from the screen (on which the programming is done) to the physical environments (i.e. the robot). In this paper, we describe an experiment aiming at studying the effect of using augmented reality (AR) representations of sensor data in a robotic learning activity. We designed an AR system able to display in real-time the data of the Infra-Red sensors of the Thymio robot. In order to evaluate the impact of AR on the learner’s understanding on how these sensors worked, we designed a pedagogical lesson that can run with or without the AR rendering. Two different age groups of students participated in this between-subject experiment, counting a total of 74 children. The tests were the same for the experimental (AR) and control group (no AR). The exercises differed only through the use of AR. Our results show that AR was worth being used for younger groups dealing with difficult concepts. We discuss our findings and propose future works to establish guidelines for designing AR robotic learning sessions.
Enhancing rural destinations’ loyalty through relationship quality Lamejora de la lealtad a los destinos rurales a través de la calidad relacional

Purpose – The literature on the factors generating loyalty towards tourism destinations has seldom focussed its attention on relationship marketing, which has left a gap in the understanding of destination loyalty. This paper aims to examine the influence of relationship quality on rural destination loyalty, approaching this through the variables of trust, attachment and satisfaction. Design/methodology/approach – This study used a quantitative methodology based on an on line survey conducted in Spain. The sample consisted of 464 tourists who participate in rural tourism. The analysis of the proposedmodel was carried out based on the partial least squares method. Findings – The results confirm that the model has a substantial to moderate explanatory capacity for overall satisfaction and loyalty, in which overall satisfaction acts as a mediator between the variables that make up relationship quality in reference to loyalty. Research limitations/implications – The main limitations of this research arise from the scarcity of works which aim to understand relationship quality in tourism destinations. To broaden results, it should be applied in other tourism destinations, products, services and experiences. Practical implications – Destination managers should give relationships a special role in their tourism development programmes in rural tourism contexts. Social implications – Rural tourism destinations and companies are generally small-sized organisations that need managerial tools. These can benefit from developing sustainable relationships. © Helena Alves, Ana María Camp on-Cerro and José Manuel Hernández-Mogoll on. Published in Spanish Journal of Marketing – ESIC.

Generation of Realistic Virtual Garments on Recovery Human Model

Displaying a variety of fabrics on a customized character could help customers choose which fabric is more suitable for themselves and help customers choose clothing. However, it is not an easy task to show realistic garment on customized virtual character. As a result, we propose a stable finite element method (FEM) model which is stable to approximate stretching behaviors. At first, we measure four kinds of cloth materials with measurement techniques to research elastic deformations in real cloth samples. Then, we use the parameter optimization method by fitting the model with measurement data. For promoting the display of realistic fabrics, we recover 3D human in shape and pose from a single image automatically. Human body datasets are constructed at first. Then, CNN-based image retrieval in shape and skeleton-based template matching method in pose are combined for 3D human model recovery. To enrich human body details, we synthesize the human body and 3D face with spatial transformation. We compared our proposed method of recovering 3D human from a single image with the state-of-the-art methods, and the experimental results show that the proposed method allows the recovered virtual human to put on garment with different fabrics and significantly improves the fidelity of virtual garment.
Enzymatic dissociation of long muscles from mice: a model for the study of skeletal muscle fiber types

SUMMARY The enzymatic dissociation of short muscles from mice, such as flexor digitorum brevis, has allowed a great accumulation of physiological, pharmacological and biochemical knowledge about skeletal muscle. However, this body of knowledge has been restricted to the types of fibers present in these muscles. Information about the other fiber types has been limited and has been primarily obtained by the manual isolation of fibers from other species, typically rats, via a difficult and time-consuming procedure. In this report, the author describes a technique for the enzymatic dissociation of long muscles, such as soleus or extensor digitorum longus (EDL), which can be applied to study a wider spectrum of fiber types and larger quantities of cells. Additionally, the kinetics of Ca 2+ transients obtained in soleus and EDL fibers are compared in this report. The usefulness of this methodology for other physiological, biochemical and molecular biology experiments is also discussed. This methodology introduces the possibility of using the whole spectrum of fiber types to study normal muscle biology and the pathophysiology of muscle diseases.
ANTIOXIDANT AND ANTIMICROBIAL ACTIVITIES OF

This study is part of a goal to investigate chemical composition, antibacterial, antifungal and antioxidant activities of the flower buds extracts from the Algerian Polulus nigra L. , which were collected from Djarifet mansourah at Tlemcen city in the West Northern of Algeria. In organic extracts, tanins, flavonoïds, coumarins, alkaloids and terpenoïds were the principals secondary metabolites identified from the flower buds of black poplar. Antibacterial and antifungal activities of extracts were tested using agar-well diffusion method and micro-well determination of MIC assay against eleven bacteria and two Candida species. It was found that extracts of black poplar buds exhibit antibacterial and anticandidal activities with agar disk diffusion (7 to 43mm) and MIC methods (MIC= 90.33 μg/ml against several strains of bacteria and MIC=45.16 μg/ml against Candida albicans). The antioxidant effect of hydroalcoholic extract was evaluated using DPPH and FRAP assays. It was showed good and similar activity than ascorbic acid and BHA by DPPH method: IC50= 220μg/mL for hydroethanol extract.
SOME NOTES ON THE BREEDING BEHAVIOUR OF THE ORIENTAL MAGPIE ROBIN (COPSYCHUS SAULARIS) FROM UTTARAKHAND, INDIA

Studies on behavioural ecology of birds provide essential information in the field of evolutionary biology. Ornithology can develop and mature mainly by the collection and proper interpretation of real data collected in the field on different aspects of birds’ life (Nolan, 1978). The breeding characteristics of a species provide insights into the selection pressures that individuals of that species have faced over time. Long term and systematic data on the breeding ecology of previously unstudied species make it possible to conduct more rigorous comparative tests to determine what factors are responsible for the differences in breeding parameters between species (Dowling, 2003).
MOTUMA HIRPASSA MINDA AN ANALYSIS OF READING STRATEGIES USED BY AMBO UNIVERSITY STUDENTS, OROMIA, ETHIOPIA

Concerned by increased problems about the students’ reading quality, this study was carried out to investigate the reading approach of English major students of Ambo University. To achieve this objective, all 52(31 male and 21 female) English major students of the University were purposely selected for the study because the number of the students is small to manage. Both quantitative and qualitative data were obtained from the respondents through Reading Achievement Tests, Questionnaire and Structured Interview and analyzed accordingly. The study mainly focused on the students’ approach to reading (adapted top-down or bottom-up) and the students’ ability to identify the main ideas and details, explicitly stated and implied information, the purpose and the tone of authors in five different reading genres: dialogues, directions, article, essays, and poems. The overall result of the study showed that 89.7% of the University students were exclusively limited to bottom-up approaches to reading and frustrated to determine the main ideas and implied information in the texts. In other words, no student answered more than 78% in reading comprehension items correctly in the tests. Moreover, half of the students could not answer above 50% in the comprehension questions. Therefore, the prescriptions for the solution to the problem lies in bringing about improvement in the students’ interactive approach to reading and thereby, improve students’ ability to identify the main ideas and details, explicitly stated and implied information, the purpose and the tone of authors in different reading genres: dialogues, articles, essays, directions and poem.
Democratic Processes to Overcome Destructive Power Relations and Sustain Environmental Education in Primary Schools: Implications for Teacher Education in Tanzania1

This paper is based on a follow-up study of a participatory action research (PAR) project aimed at improving environmental education (EE) in teacher colleges and primary schools in Tanzania. The aim of the current paper is to discuss the power relations involved in sustaining the EE process initiated in the PAR project. We developed two research questions: “To what degree do the democratic processes in the PAR project enable the tutors, teachers, and local community members to continue developing EE while simultaneously addressing the environmental challenges? ” and “In what ways do the power relations influence the further development of EE? ” We conducted focus-group discussions and interviews with the college dean, tutors from the selected teacher college, and teachers from primary schools who had participated in the project, one year after the researcher left the project. In addition, we interviewed village leaders and local experts. Finally, we undertook nonparticipant observations. We found that, despite hierarchical decisions to transfer teachers, the EE learning processes started in the PAR project continued. We discuss the possibilities for strengthening democratic relations in the educational system in Tanzania through PAR, and recommend the inclusion of PAR in the teacher education curriculum in Tanzania.
Evaluation of Commercial “Carbon Quantum Dots” Sample on Origins of Red Absorption and Emission Features

The commercially acquired aqueous solution of “carbon quantum dots” sample was evaluated by optical absorption and fluorescence emission methods; in reference to aqueous dispersed small carbon nanoparticles and representative carbon dots prepared from chemical functionalization of the carbon nanoparticles. The results suggest a very low content of carbon that is associated with nanoscale carbon particles/domains in the as-supplied sample; and likely significant contamination by dye-like species/mixtures. In the absence of any information on the synthesis and history of the commercial sample, the possible cause of the contamination was illustrated by an example on similar dye formation in the one-pot carbonization synthesis of “red carbon dots” from citric acid–formamide precursor mixtures under too mild processing conditions that were insufficient for the intended carbonization. The negative impacts to the carbon dots research field by the apparent proliferation and now commercial availability of carbon-deficient or even largely carbon-less “carbon quantum dots”, which are more susceptible to dye contamination or dominance, are discussed.
Safety Climate in a Ghanaian Industry: Its Measurement and Relative Influence on Employee Safety-Oriented Behaviour by Kofi Adutwum A thesis submitted in partial fulfilment of the requirements for the Master of Philosophy (MPhil) degree in Human Development

In this study, a cross sectional safety climate survey was carried out within a Ghanaian mining industry and the psychometric properties of the scale used were examined. The study scale was developed by extending Zohar’s (2000) model of unit level safety climate to incorporate aspects of both supervisor and co-worker value for safety. This scale was then administered to a sample of technical mine workers out of which 273 (representing a response rate of 92%) returned their completed scale. Principal component analysis revealed four underlying safety climate dimensions; each of which had an acceptable Cronbach’s alpha reliability. Further, all the identified dimensions discriminated effectively among workers on the basis of their work locations and positions on the organizational hierarchy.
Topological Characterization of the Crystallographic Structure of Titanium Difluoride and Copper (I) Oxide

Owing to their distinguished properties, titanium difluoride (TiF2) and the crystallographic structure of Cu2O have attracted a great deal of attention in the field of quantitative structure–property relationships (QSPRs) in recent years. A topological index of a diagram (G) is a numerical quantity identified with G which portrays the sub-atomic chart G. In 1972, Gutman and Trinajstić resented the first and second Zagreb topological files of atomic diagrams. In this paper, we determine a hyper-Zagreb list, a first multiple Zagreb file, a second different Zagreb record, and Zagreb polynomials for titanium difluoride (TiF2) and the crystallographic structure of Cu2O.

LOCAL DEFORMATION PROPERTIES OF SEGREGATED SAND SPECIMEN IN HOLLOW CYLINDRICAL TORSIONAL SHEAR TESTS

ABSTRACT: A hollow cylindrical torsional shear apparatus with a special image analysis technique is employed for understanding the deformation of segregated specimen that is reconstituted by depositing Katori sand particles in three layers through water sedimentation. This specimen preparation is used to model reclaimed land constructed by dredging and pumping method. This technique involves the use of a latex membrane with dots marked in a grid pattern with approximately 5 mm spacing. These dots are tracked using a digital camera that synchronously shoots the membrane surface at desired time intervals. Corrections of coordinates are applied for the effects of cylindrical shape of specimen, the camera lenses, and refraction from lighting through water in the cell. It was observed that in drained monotonic loading test, formation of shear band was initiated at interface layers before the shear stress reached its peak value. In undrained cyclic loading test, the specimen deformation did not start uniformly but started gradually.
Stability guarantees for nonlinear discrete-time systems controlled by approximate value iteration

Value iteration is a method to generate optimal control inputs for generic nonlinear systems and cost functions. Its implementation typically leads to approximation errors, which may have a major impact on the closed-loop system performance. We talk in this case of approximate value iteration (AVI). In this paper, we investigate the stability of systems for which the inputs are obtained by AVI. We consider deterministic discrete-time nonlinear plants and a class of general, possibly discounted, costs. We model the closed-loop system as a family of systems parameterized by tunable parameters, which are used for the approximation of the value function at different iterations, the discount factor and the iteration step at which we stop running the algorithm. It is shown, under natural stabilizability and detectability properties as well as mild conditions on the approximation errors, that the family of closed-loop systems exhibit local practical stability properties. The analysis is based on the construction of a Lyapunov function given by the sum of the approximate value function and the Lyapunov-like function that characterizes the detectability of the system. By strengthening our conditions, asymptotic and exponential stability properties are guaranteed.
Application of Remote Sensing and GIS for Integrated Water Resources Management in Southern Africa

Optical and microwave remote sensing data has been evaluated for land cover classification, classification of land degradation as well as settlement detection to provide areal and actual contributions to water resources management in Southern Africa. Apart from the development of a GIS-based Decision Support System to account for competing stakeholders’ water demands and to address water allocation conflicts with respect to socio-economic aspects, the focus was also on simulating hydrological and erosion dynamics using deterministic, physically-based models with remote sensing input. The result, an integrated water resources management system, is a computer based toolset designed as an assembly of tested, validated and well documented procedures comprising the above outlined key technologies. ZUSAMMENFASSUNG Fernerkundungsdaten aus dem optischen und dem Mikrowellenbereich wurden hinsichtlich der Klassifizierung von Landnutzung und –degradation sowie der Siedlungserkennung ausgewertet, um damit einen flächenhaften und aktuellen Beitrag zu wasserwirtschaftlichen Problemen im südlichen Afrika zu leisten. Neben der Entwicklung eines GIS-basierten Decision Support Systems unter Berücksichtigung von Wasserangebot, -qualität, -bedarf und zuteilung der unterschiedlichen Nutzergruppen stand dabei die Simulation von Wasserund Stoffflüssen unter Verwendung von physikalisch basierten Modellen mit Fernerkundungsinput im Vordergrund.

Antioxidant Activity and its Interaction Effect on Polyherbal Formulations of Nephrodium inophyllum, Polygonum minus Annona squamosal L. and Stevia rebaudiana

Article history: Received 9 April 2019 Received in revised form 10 August 2019 Accepted 5 September 2019 Available online 15 September 2019 Antioxidant activities have a great potential on various plant extracts due to the complexity of the composition of bioactive compounds present in the plants. Besides that, various combinations of plants can give possible interactions such that synergistic, antagonistic and indifferent between particular compounds which is importance in development of food products. Therefore, the objective of this study is to determine and evaluate the antioxidant activity and the possible interaction effect on aqueous extracts of leaves of Nephrodium inophyllum (pakis merah), Polygonum minus (kesum), Annona squamosal L. (nona) and Stevia rebaudiana through in-vitro assay. In this study, the antioxidant activity of the extracts individually and their different combinations were analyzed by total phenolic content (TPC), total flavonoid content (TFC), 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and lipid peroxidation inhibition (LPI) assay. Meanwhile, the interaction effect was evaluated by comparing the experimental antioxidant activity of the mixtures with calculated theoretical values and the interactions of the compounds were determined. The results depicted that individual extract of N. inophyllum had significant flavonoid content and lipid peroxidation inhibition while P. minus has the highest phenolic content and percentage inhibition DPPH compared to other plant extracts. For the interaction effect, synergism was exhibited on only four combinations of plant extracts for all assays conducted with the highest one was shown on DPPH assay for combination of N. inophyllum and A. squamosal L. This proved that there was a little molecular interaction between particular phenolics or flavonoids compound found in plant extracts. Out of all studied plant extracts, there was only one antagonistic interaction between P. minus and A. squamosal L on DPPH assay. However, indifferent effect on other compounds was revealed in the majority of all plant extract combinations for all assays. Hence, this present study justifies the aqueous extracts have significant antioxidant properties individually thus it gave possible interaction effects that could contribute for future design in food industries.
KNU-HYUNDAI’s NMT system for Scientific Paper and Patent Tasks onWAT 2019

In this paper, we describe the neural machine translation (NMT) system submitted by the Kangwon National University and HYUNDAI (KNU-HYUNDAI) team to the translation tasks of the 6th workshop on Asian Translation (WAT 2019). We participated in all tasks of ASPEC and JPC2, which included those of Chinese-Japanese, English-Japanese, and Korean->Japanese. We submitted our transformer-based NMT system with built using the following methods: a) relative positioning method for pairwise relationships between the input elements, b) back-translation and multi-source translation for data augmentation, c) right-to-left (r2l)-reranking model robust against error propagation in autoregressive architectures such as decoders, and d) checkpoint ensemble models, which selected the top three models with the best validation bilingual evaluation understudy (BLEU) . We have reported the translation results on the two aforementioned tasks. We performed well in both the tasks and were ranked first in terms of the BLEU scores in all the JPC2 subtasks we participated in.
BOUN-ISIK Participation: An Unsupervised Approach for the Named Entity Normalization and Relation Extraction of Bacteria Biotopes

This paper presents our participation to the Bacteria Biotope Task of the BioNLP Shared Task 2019. Our participation includes two systems for the two subtasks of the Bacteria Biotope Task: the normalization of entities (BB-norm) and the identification of the relations between the entities given a biomedical text (BB-rel). For the normalization of entities, we utilized word embeddings and syntactic re-ranking. For the relation extraction task, pre-defined rules are used. Although both approaches are unsupervised, in the sense that they do not need any labeled data, they achieved promising results. Especially, for the BB-norm task, the results have shown that the proposed method performs as good as deep learning based methods, which require labeled data.
