TRACKING LOWER-LIMB EXERCISES WITH WEARABLE SENSORS

O’Reilly, MA, Whelan, DF, Ward, TE, Delahunt, E, and Caulfield, B. Technology in strength and conditioning tracking lower-limb exercises with wearable sensors. J Strength Cond Res 31(6): 1726–1736, 2017—Strength and conditioning (S&C) coaches offer expert guidance to help those they work with achieve their personal fitness goals. However, because of cost and availability issues, individuals are often left training without expert supervision. Recent developments in inertial measurement units (IMUs) and mobile computing platforms have allowed for the possibility of unobtrusive motion tracking systems and the provision of realtime individualized feedback regarding exercise performance. These systems could enable S&C coaches to remotely monitor sessions and help gym users record workouts. One component of these IMU systems is the ability to identify the exercises completed. In this study, IMUs were positioned on the lumbar spine, thighs, and shanks on 82 healthy participants. Participants completed 10 repetitions of the squat, lunge, single-leg squat, deadlift, and tuck jump with acceptable form. Descriptive features were extracted from the IMU signals for each repetition of each exercise, and these were used to train an exercise classifier. The exercises were detected with 99% accuracy when using signals from all 5 IMUs, 99% when using signals from the thigh and lumbar IMUs and 98% with just a single IMU on the shank. These results indicate that a single IMU can accurately distinguish between 5 common multijoint exercises.

Amped about AMP? Time to look more carefully

Numerous reports suggest that the Accelerated Mobile Pages (AMP) project can increase publisher traffic because of special promotion by Google. We present the first formal statistical report on the relationship between AMP adoption and publisher traffic. We found that AMP adoption resulted in a 22% average Google traffic increase for the 159 publishers we analyzed. But, because website traffic is very noisy
Secure Lightweight Routing Scheme for Energy Efficient Wireless Sensor
Networks

The technology revolution in wireless communications and micro-electro-mechanical systems (MEMS) directly affects the development of wireless sensor networks (WSNs), which are used in several application areas, including the military, home, and environment. One of the best categories of routing networks in WSNs are hierarchical protocols (cluster-based). The wellknown protocols in this category include the Low Energy Adaptive Clustering Hierarchy (LEACH). However, the LEACH is vulnerable to many attacks. To provide cryptographic protection against outsider attacks, a modified version of LEACH, called Enhancing Secure LEACH (MS-LEACH) protocol, is used. MS-LEACH enhances security but increases power consumption. To maintain an acceptable level of security and decrease the power consumption of secure LEACH protocols, the present research proposes a Secure Lightweight LEACH (SLWLEACH) scheme. The simulation results show that this proposed SLW-LEACH protocol outperforms the MS-LEACH in terms of ne
Automated Playtesting of Platformer Games using Reinforcement Learning

Platformer games are popular in the video game industry and their design require much efforts from game companies. As part of the design process, playtesting is key for improving the gameplay before game release. Playtesting is the quality assurance phase of the game development cycle where people are hired to play the game, report bugs and provide feedback regarding the playability of the game. This feedback could be used for game balancing (process of tuning game rules to prevent them from being ineffective or provide undesirable results). However, playtesting may be expensive if done manually and may require several iterations, resulting in high budget requirement and time for game companies. In this thesis, we investigate a way to automatically playtest 2D platformer levels using a combination of deep reinforcement learning and curriculum learning, for both quality assurance and game balancing. Deep Reinforcement Learning has contributed greatly in playing games (Atari and Dota 2) and in this thesis, we will try to replicate the results to playtest games. Curriculum learning is an approach that has shown promising results thus we will explore it to derive useful results. We develop our APT tool by training an artificial intelligence (AI) agent on several different platformer levels following a curriculum, and use the trained agent to playtest newly-created levels. Our APT is able to identify areas of the level that needed design improvements and further gameplay balancing. We contribute a reliable APT tool for designers that wish to easily design 2D platformer games and a discussion of how our results extend to APT at-large.
SMART Natural Circulation Cooldown Performance Analysis using MARS-KS

The SMART (System integrated Modular Advanced ReacTor) is first small and modular reactor (SMR) which received standard design certification from the NSSC (Nuclear Safety and Security Commission), Korean nuclear regulatory agency. Its primary side which includes reactor core, pressurizer, reactor coolant pumps (RCPs), and steam generators (SGs) is implemented inside the reactor vessel. It also has passive residual heat removal system (PRHRS) in the secondary side to remove core decay heat. After the Fukushima accident, SMART further enhanced its safety system for a fully passive safety system through implementing 4 trains of passive safety injection system (PSIS) which contains core makeup tank (CMT) and safety injection tank (SIT) as well as the pressure balance line (PBL) in each train. In this study, preliminary analysis for the SMART natural circulation cooldown is performed based on the analysis methodology of the SMART natural circulation cooldown using MARS-KS [1]. According to the analysis methodology, passive safety system should cooldown reactor to safe shutdown condition within 36 hours and maintains safe shutdown condition until 72hours after the reactor trip without any operator actions.
Determinants of E-Learning System Adoption among Ghanaian University Lecturers: An Application of Information System Success and Technology Acceptance Models

This study aims at exploring the factors that influence e-learning adoption among university lecturers. It is realized that the adoption rate of e-learning in the context of developing countries is very low and this has called for more research. A sample size of 131 respondents was selected using both convenience and purposive sampling technique. Questionnaires were used to elicit information from respondents. Data analysis was performed using SPSS and SmartPLS application. The study found eight of the eleven hypotheses tested to be statistically significant whiles the remaining three factors were found to be statistically insignificant. This study is limited to only one university (University of Ghana, Legon). Sakai is a software used by both students and lecturers to facilitate distance learning. So, the concentration of the analysis on just lecturers may not give the clearest picture of the adoption of the software. The results of this study will help developers of an e-learning system to improve users’ adoption by critically looking at these factors. Sufficient support and training should also be provided to both administrators and instructors to improve their adoption of rate. This study is one of the first kind to investigate university lecturers’ e-learning adoption specifically in a Ghanaian University by applying the Information System Success and Technology Adoption Models. The study, therefore, contributes to the research gap on the lack of e-learning studies in developing countries that have emphasized the use of eLearning systems.
The Role of the Indonesian Muslim Community Identity in Strengthening Indonesia-Malaysia Relations

This article departs from the reality that identity played a significant role in Indonesia-Malaysia brotherhood relations. In addition, Malaysia is home to many Indonesian diasporas, either to work or study. In fact, the Indonesian diaspora still maintains a connection with the motherland through communities amid of identity issues with the Malaysian local. For instance, the emergence of anti-Malaysian versus anti-migrant sentiments, the use of a controversial term called ‘ Indon ’ and ‘ Malingsia ’ in the middle of Muslim brotherhood identity. Therefore, using a qualitative approach supplemented with unstructured interviews, this study found that Islamic identity obviously contributed to the harmony of people to people relations between the two nations. Indeed, Islamic identity became a catalyst especially for many Indonesian workers to build close contact with the Muslim local community. These findings are important for sociology and international relations students and researchers.
Vibration Response of Free and Force Analysis of a Rectangular Plate

This paper presents the influence of free and forced vibrations on thin the plate of (50cm length, 30 cm width, 0.5 mm thickness), made from steel 37 with two types of supports, firstly when it is fixed from two sides and other sides are free (CFCF) and secondly when one end of the plates is fixed and the other three sides are free (CFFF). As well as, this work studies the mode shapes and natural frequency of the plate. When the frequency is applied on the plate with different magnitudes (4,6,8,10) Hz, the amplitude of vibration decreased more than free vibration and when the frequency increased, the amplitude of the vibration increased or decreased but still less then at free vibration depending on the type of support. Ansys and MATLAB software were used to find the natural frequency and to enter the boundary conditions of the plate for comparison purposes.
Impact of Reject of Dairy Wastewater into the Aquatic Environment: Case of the Bayo Dairy Company (Brazzaville-Congo)

The development of industrial activities is the source of the production of large quantities of wastewater. The last-mentioned are rejected in the environment often without any prior treatment and have serious short-term and sometimes long-term environmental consequences. The objective of this work is to assess the environmental impacts and to propose a process for treating wastewater of reject from Bayo dairy in Brazzaville-Congo. The samples were taken at four (4) stations before, during and after production of dairy products. Multivariate statistical analysis of the physicochemical data was carried out using Statistica 7.1 software. The results obtained show that the wastewater from the Bayo dairy has a basic pH which fluctuates between 8.32 and 9.17 with standard temperatures of reject. The salinity of the wastewater increases greatly during production, Original Research Article Litébé et al.; IJECC, 10(2): 1-12, 2020; Article no.IJECC. 54683 2 which shows rising mineralization. The contents of MES (49.78-181.80 mg/L), MO (40.23-72.64 mg O2/L), COD (51.08-98.91 mg O2/L), BOD5 (34.80-59.50 mg O2/L) and the turbidity (26-179) NTU are moderately high and reflect an increase pollutant load before, during and after production of dairy products in stations S2 and S3. The COD/BOD5 ratio reveals that the Bayo dairy wastewater is moderately biodegradable before, during and after production with a biodegradability coefficient which varies between 1.40 and 1.78. The ACP approves possible industrial pollution from wastewater from the Bayo dairy and reports on the impact of the rejects in the environment. Thus, this study is a contribution to raising awareness among the Congolese population and decisionmakers on the quality of wastewater rejected by local industries.
Inhomogeneity and Segregation Effect in the Surface Layer of Fe-Doped SrTiO3 Single Crystals

The effect of Fe doping on SrTiO3 single crystals was investigated in terms of crystal and electronic structure over a wide temperature range in both oxidizing and reducing conditions. The electrical properties were thoroughly studied with a special focus on the resistive switching phenomenon. Contrary to the undoped SrTiO3 crystals, where isolated filaments are responsible for resistive switching, the iron-doped crystals showed stripe-like conducting regions at the nanoscale. The results showed a non-uniform Fe distribution of as-received crystals and the formation of new phases in the surface layer of reduced/oxidized samples. The oxidation procedure led to a separation of Ti(Fe) and Sr, while the reduction resulted in the tendency of Fe to agglomerate and migrate away from the surface as seen from the time of flight mass spectroscopy measurements. Moreover, a clear presence of Fe-rich nano-filament in the reduced sample was found.
Age-Related Changes of Some Chemical Components in the Leaves of Oriental Beech (Fagus orientalis Lipsky.)

Background and Purpose: This study presents the analysis of photosynthetic pigments, proline, total soluble protein, total amino acids, glucose, sucrose, total soluble sugars, total amount of phenolic compounds and flavonoids, malondialdehyde (MDA) and hydrogen peroxide (H2O2) concentration in the leaf samples collected from oriental beech trees, which are naturally spread in Kastamonu Province, Turkey, with differing ages, enzyme activities of ascorbate peroxidase (APX), catalase (CAT) and superoxide dismutase (SOD). Material and Methods: The research was carried out on oriental beech trees (Fagus orientalis L.) of different ages located at 1300 m high elevation in Ahlat Village of Kastamonu Province, Turkey. Oriental beech trees of different ages (≥25, ≥50, ≥100, ≥200 and ≥600 years-old) constituted the material of this study. In leaf samples taken from trees of different ages, photosynthetic pigments (chlorophyll a, chlorophyll b, total chlorophyll and carotenoid), proline, total soluble protein, total amino acid, glucose, sucrose, total soluble sugars, the amount of total phenolic compounds and flavonoids, MDA, H2O2 concentration, enzyme activities of APX, CAT and SOD, as well as the relationship between the total content of C, N and H elements and the tree ages were studied. Results: As a result of the research conducted, significant differences were determined in terms of chlorophyll, total phenolic compound, flavonoid, glucose, amounts of sucrose, nitrogenous compounds, proline, total soluble protein, MDA, H 2O2 concentrations, and the activities of APX, CAT and SOD in the leaves of oriental beech trees with differing ages. The highest content of chlorophyll a was found to be in the youngest age group of ≥25 years. Total chlorophyll is low in young trees and high in middle-aged, old and very old trees. According to the results obtained, it was concluded that the MDA and H2O2 concentrations in the trees did not vary depending on the age of trees only, but also on the genotype, environmental conditions and metabolic activities. It was concluded that the fact that the total chlorophyll, phenolic compounds and sucrose content in oriental beech trees are high and that MDA content is low could have an influence on the long life of ≥600 years-old oriental beech trees. Conclusions: The activity of photosynthesis is related to leaf characteristics more than the age of trees.
Changes in Psychology students ’ workload due to alignment with the EHEA

Alignment with the European Higher Education Area (EHEA) has involved changes in teaching methodology and in the learning process, which have led to a change in student workload. The main aim of this study is to evaluate and compare the perception of the workload of undergraduate and graduate psychology students and to analyse the nature of the changes produced by this adaptation. The sample comprised 845 students (497 readings for the licentiate’s degree and 348 for the bachelor’s degree). To measure perceived workload, the NASA-TLX scale was used. This evaluates the following dimensions: mental demand, physical demand, temporal demand, performance, and frustration/dissatisfaction; these variables were evaluated for the following academic activities: attending theoretical classes, attending practical classes, conducting group work outside the classroom, searching for material and bibliography, studying and personal work, attending tutorials, and other activities (seminars, conferences, etc.). The results show a significant increase in the perceived load of attendance in practical classes, in the performance of group work outside the classroom and in total perceived workload for bachelor’s degree students. It is concluded that adjusting to the EHEA has involved an increase in perceived workload for students. This points to a need to work in the classroom on developing interpersonal skills and planning and organization of teamwork, as well as greater coordination between teachers in the evaluation systems.

EFFECT OF HEAT TREATMENT ON CYCLIC FATIGUE, FLEXIBILITY AND PHASE TRANSFORMATION OF TWO CONTROLLED MEMORY NITI ROTARY INSTRUMENTS

Aim: The aim of this study the effect of heat treatment on flexibility, cyclic fatigue and of OneCurve nickel-titanium (Ni-Ti) rotary file (OC) and compare them with those of EdgeFile (EF) NiTi file as both files manufactured from a controlled memory wire. Methods: A sample of 45 instruments with tip size of 25 and 0.06 taper from both OC and EF were selected for the current study. The cyclic fatigue testing was performed using dynamic mode. The bending resistance was tested using the universal testing machine and files were bent until reach 45°. In addition, dispersive scanning calorimetric analysis (DSC) was carried out for identification of Af transformation temperature. An independent t-test was used in the statistical analysis and significance difference was set at p-value 0.05. Results: The EF files showed significantly greater resistance to cyclic fatigue (p<0.05). As well as, the EF exhibited less bending resistance than OC (p<0.5). The DSC analysis showed that the OC has an Af near 54°C, while the EF was near 57°C. Conclusions: The EdgeFile NiTi rotary instruments have high flexibility and high resistant to cyclic fatigue than OneCurve does when tested in dynamic mode and both have a close has an Af temperature exceeding 50˚C
Photosynthetic properties of maize hybrids under different environmental conditions probed by the chlorophyll a fluorescence

Temperatures and light intensities that deviate from optimum often affect maize (Zea mays L.) production in temperate regions. Objectives of the current study were (i) to investigate the effects of extreme temperatures and low light conditions on photosynthesis in maize hybrids, (ii) to test whether maize hybrids show distinctive reactions when subjected to different stresses, and (iii) to investigate informativeness of different fluorescence parameters in different stress conditions. Plants of five maize hybrids were subjected to: cold (Co), low light (LL), heat (H), and severe heat (SH) treatments and field (F) conditions along with control (C), and chlorophyll a fluorescence (ChlF) was measured. ChlF transients were shown to respond to different treatments by changing the appearance of OJIP band, mostly at steps J and I, while the appearance of the K step was confirmed as a good indicator of temperature stress. PC analysis revealed grouping of parameters with PCs according to their informativeness. Parameter ψEo, was shown to be in most defined by the F treatment, probably due to higher light intensity compared to C. Variables regarding electron transport and dissipation showed specific reactions to H and SH treatments. Co and LL conditions caused specific changes in in parameters VJ and VI. Further research on usability of ChlF in maize breeding is needed, as it represents the data-rich, easy to measure method, providing the biological framework for explanation of reactions to different stresses.
MVS-Pheno: A Portable and Low-Cost Phenotyping Platform for Maize Shoots Using Multiview Stereo 3D Reconstruction

Plant phenotyping technologies play important roles in plant research and agriculture. Detailed phenotypes of individual plants can guide the optimization of shoot architecture for plant breeding and are useful to analyze the morphological differences in response to environments for crop cultivation. Accordingly, high-throughput phenotyping technologies for individual plants grown in field conditions are urgently needed, and MVS-Pheno, a portable and low-cost phenotyping platform for individual plants, was developed. The platform is composed of four major components: a semiautomatic multiview stereo (MVS) image acquisition device, a data acquisition console, data processing and phenotype extraction software for maize shoots, and a data management system. The platform's device is detachable and adjustable according to the size of the target shoot. Image sequences for each maize shoot can be captured within 60-120 seconds, yielding 3D point clouds of shoots are reconstructed using MVS-based commercial software, and the phenotypic traits at the organ and individual plant levels are then extracted by the software. The correlation coefficient (R2) between the extracted and manually measured plant height, leaf width, and leaf area values are 0.99, 0.87, and 0.93, respectively. A data management system has also been developed to store and manage the acquired raw data, reconstructed point clouds, agronomic information, and resulting phenotypic traits. The platform offers an optional solution for high-throughput phenotyping of field-grown plants, which is especially useful for large populations or experiments across many different ecological regions.
