Abstract The safety calculation of the RSG-GAS reactor core needs to be done if new high-density fuel is used in the RSG-GAS core. The use of new high-density fuels is very much needed in the RSG-GAS core so that it is necessary to calculate its safety. When using high density fuel there will be a “bottle neck” effect where there is a problem with the fuel and cladding interaction. According to previous researchers this can be overcome by adding metal elements Si, Ni or Ti to fuel. However, with the addition of metal elements Si, Ni or Ti to the fuel, it needs to be analyzed in the RSG-GAS core. The analysis was carried out calculations using a computer program by simulating the Si metal used 1%, 2%, 3% 4% and 5% in the fuel. The calculation of the additional metal element in the high-density fuel effect on the reactivity of the RSG-GAS core was carried out with the WIMSD-5B and Batan-FUEL programs. The WIMSD-5B program is a computer program consisting of several modules including the transport module which is used for the calculation of the generation of macroscopic constants for the 19.75% enriched uranium silicide fuel and the density of 4.8 gU/cc as a function of degree of burn. Core calculations were performed using a neutron diffusion program, namely Batan-FUEL. By calculating the core criticality at operating temperature, the core neutronic parameter values are obtained. The results of the analysis show that the amount of Si 5% in the high density fuel matrix can solve the bottle neck problem and the neutronic parameters are still within the safety limit. This value will determine how much the value of the fuel burn up and control rods are in accordance with the acceptance criteria so that the safety analysis can be carried out on the RSG-GAS core using high density. From the analysis, it was found that the addition of the element Si in the high-density fuel matrix did not find any significant changes in core reactivity and neutronic parameter.

The field of application of the protected microprocessor systems includes information security functions: authentication of subjects and objects of information interaction, information encryption, integrity control, access control,key management. Today, the urgent task is to establish the security of microprocessor-based systems using a variety ofcomputer simulation software environments. The work analyzes the most effective and affordable computer simulation programs for microprocessor systems and gives practical recommendations for their use. It has been shown thatthe most powerful computer-aided design system is the Proteus software suite which allows simulating the operationof various microprocessor devices with support for several microcontroller families from different manufacturers. Themain advantages include: performing all stages of development in a single environment; the ability to write, debug, andtest firmware, generate diagnostic messages to find programming errors. Using Multisim in the educational processmakes it possible to: review and change the status of the register content, program memory and data, stack cells andbit configuration; visualize the result of the execution of a single command or a program as a whole; demonstrate thepractice of joint use of languages C and Assembler in one project in order to optimize the program; to study the basics ofoperation and features of peripheral devices functioning. However, the limited set of microcontrollers in the Multisimprogram imposes significant restrictions on the possibility of using it for development of real projects. The computersimulation program TINA has a russified interface that is much easier compared to the Proteus with an ability to enter allthe information about the created project into one file. Compared to Multisim, the TINA library contains significantlymore microcontroller models, and the built-in programmer allows modifying programs and observing the results. Beingable to use the free version of TINA-TI and having an online version of TINACloud using cloud technologies makes thisprogram very useful for education. Web service offers many educational resources and the ability to perform research onthe design of microprocessor systems.

Materials and Methods. For the study there were used the elements of mathematical statistics, experimental research design theory, correlation and regression analysis, automatic control theory and computer simulation. Real experiments were carried out on a laboratory sample of a digital dynamic local lighting system. Computer simulation was performed in the SimInTech program. Results. A computer model for a digital ACS of lighting has been developed. The tunings of the PI controller were calculated using the CHR, VTI, and Kopelovich methods. A comparative estimation of the control process quality was carried out using graphs of transient processes obtained by computer simulation. The reliability of the results of computer simulation of ACS lighting has been confirmed experimentally. Discussion and Conclusion. High regulator performance indicators for the digital ACS of lighting were ensured by a PI controller with kP = 14.027∙10−3 and TI = 145.72 ms calculated using the Kopelovitch method.

Abstract - In taking a video on the camera results that are not much movement are needed, so that the video can be seen properly by the audience. In addition, the video does not have a lot of distortion which is caused by being unstable in its capture. Then a Camera Stabilizer is needed so that the resulting video remains stable. This camera stabilizer uses a computer device in making this program needed to make it easier for the operator to set the desired angle. In order to obtain the best stability, a tuning of the Proportional Integral Derivative (PID) controller parameter is performed. In this tuning we can find out the values of Proportional gain (Kp), Integral Time (Ti), and Derivative Time (Td). The PID controller can provide action to the servo motor controller based on the error obtained, the desired servo motor rotation value is called the setpoint. LabView software is used as a driver, motor speed control. Keyword : LabView, servo motor, arduino, accelerometer, computer

Some Aspects of Continuous Casting of Low Carbon Microalloyed Steels with Niobium and TitaniumAn analysis of the causes of transverse corner and surface crack formation during continuous casting of low carbon niobium and titanium-containing steel into square billets is presented in this paper. Using X - ray analysis method, the chemical composition of non- metallic phases inside corner cracks was determined. The temperature ranges of the occurrence of nitrides and carbonitrides of Nb, Ti and Al were established using FactSage 6.2., a commercial computer program. The need for the precise selection of cooling conditions during casting of billets both in the mould and in spray cooling regions was pointed out with the aim of obtaining the optimum surface, and particularly corner temperature of the billet before its entrance to the straightening stand.

Introduction to the Fe-C-X system: Si, Mn, Al and Nb, Ti, V, B allow the ultimate tensile strength and ductility of steel to be increased at the same time. Therefore, multiphase steels of the TRIP, DP, MART and CP are the steels of the future. The scientific aim of the researches were to obtain new basic information on alloying process of liquid steel in a tundish with the use of the pulse–step method. The facility under investigation was a single outlet tundish being a component of a slab continuous casting machine. Computer simulations of the liquid steel flow and alloy behaviour in turbulent motion conditions were done using the Ansys-Fluent computer program. For generating the computational grids, Gambit program was used. For pulse–step method optimisation two aspects were considered. At first numerical simulations were performed for the selection of the time interval between the pulse feed of the first alloy batch and the continuous feed of subsequent alloy batches in order to maintain the required homogenisation level. Next simulations were done for determination of the mass of the pulse charge that ensures not only the attainment of the 95% homogenisation level, but also the limitation of alloy concentration peaks occurring in the liquid steel and going beyond the 95% homogenisation zone. On the basis of numerical investigations the mixing curves and time mixing for different variants of pulse-step method optimization were obtained.

Full textAbstract:
The application of image analysis techniques to the characterization of wear particles from failed joint replacements has been described. Wear particles were extracted from periprosthetic tissues collected during revision surgery. Chemical digestive methods were used to separate the wear particles from the biological soft material. The particles isolated were examined by optical and scanning electron microscopy. Digitized particle images were analysed on a Macintosh computer by a specially developed software and by the image analysis program ‘Prism’. The following numerical descriptors were used to characterize the particles: particle size, boundary fractal dimension and shape parameters such as form factor, roundness, convexity and aspect ratio. Elemental composition of the particles was determined by energy dispersive X-ray spectroscopy. Three selected types of wear particles were analysed and compared: titanium (Ti)-based and calcium (Ca)-based particles from a hip prosthesis and ultra-high molecular weight polyethylene (UHMWPE) particles from a knee prosthesis. The particles exhibited significantly different sizes and their shape numerical descriptors were also different. From the results obtained it appears that computer image analysis of wear particle morphology can be employed to determine the wear processes occurring in the joints. In some cases, the condition of the joint can also be assessed based on this analysis.

Full textAbstract:
In this research work, a new analytical model has been developed to predict the temperature distribution during plasma arc welding of thin Ti-6Al-4V sheets. Dhinakaran’s model based on a three-dimensional parabolic Gaussian heat source is considered as a plasma arc heat source moving on a semi-infinite body to derive the analytical model and the same heat source model is substituted in the three-dimensional Fourier’s law of heat conduction and implemented in the finite element package. Thermo physical properties, such as density, specific heat, and thermal conductivity, are used as temperature-dependent properties in finite element simulation. Numerical simulation is carried out using COMSOL. The new analytical model is expressed as a function of three-dimensional spatial co-ordinates and the time co-ordinate. A computer program has been written to solve the analytical model in order to obtain the distribution of transient temperature at any point of interest. The transient temperature distribution predicted by the analytical model has been compared with both the experimental result and the numerical result. Experimental work is carried out to measure the thermal cycle during welding. The thermal cycle is measured by using an infrared thermometer. Very good correlation has been obtained between the predicted transient temperature by analytical solution and the measured temperature, as well as the finite element simulation result. This provides a reliable alternative for using these analytical solutions in the future to obtain the thermal cycle, distortion, and thermal stress during plasma arc welding.

Abstract: The use of smartphones in the learning process in higher education can be viewed from two opposing sides. On the positive side, smartphones can make it easier for students to access online learning materials. On the negative side, a smartphone is considered to be able to disrupt the learning process when students use it to access irrelevant content. The difference in generation characteristics between students and lecturers determines the formation of their respective perspectives on the use of IT devices, especially smartphones, for classroom learning. This research focuses on study programs related to the use of smartphones in classroom learning, taking into account the knowledge of mobile learning, features on smartphoen and barriers to the use of smartphones for learning. The results showed the lecturers there were significant differences between the Economics and Education study programs and counseling in assessing whether smartphones can motivate students to learn, and also differences in views about the use of video watching features for classroom learning in Computer and Education study programs. In students there are differences of views between Economics and Education study programs in assessing whether smartphones can save time studying. Lecturers and Students who lack knowledge about technology are likely to feel worried about using smartphones in classroom learning.

In 2002, Grossman and Luca searched for terms of the sequence (tn(2))n, which are expressible as a sum of factorials. In this paper, we continue this program by proving that, for any ℓ≥1, there exists an effectively computable constant C=C(ℓ)>0 (only depending on ℓ), such that, if (m,n,r) is a solution of tm(r)=n!+(n+1)!+⋯+(n+ℓ)!, with r even, then max{m,n,r}<C.

The present work is focused on analyzing the thermodynamically equilibrium path of structure formation in a multi-component Fe-W-Mo-Cr-Ti-Mn-Si alloy of tribotechnical purpose, containing 0.72 wt. % C and 2.75 wt. % B is analyzed. Computer simulation of the crystallization process was performed using the program “Thermo-Calc Software”. It was found that the alloy belongs to the hyper-eutectic compositions, since its crystallization begins at 1472 oC with the formation of primary boride WB and carbide TiC. After a series of subsequent eutectic reactions (in the range of 1126-923 oC) and solid-phase transformations, a set of equilibrium phases is formed in the alloy, which at room temperature consists of borides WB, MoV, Fe2B, Cr4B, Mn4B, carbides TiC, M7C3, and ferrite. The total volume fraction of borides and carbides is 45.05 vol. %. A comparison of the obtained data with the results of the study of the manufactured alloy showed that the simulation with “Thermo-Calc Software” provides satisfactory adequacy in predicting the structure in the alloys of the selected alloying system.

Maleo bird (Macrocephalon maleo) is the one of protected bird’s species and originated from Sulawesi island of Indonesia. This study was carried out to obtain the growth curve of body weight (BW) in mixed-sex Maleo birds from hatching to yearling ages. The growth curve in this study was calculated with non-linear regression of Logistic (L) and Gompertz (G) models using CurveExprt 1.4. computer program. The primary data in this study was cited from previous study through a literature study. Research showed that the asymptotic weight (A) in birds was 1825.34 g (L) and 3429.23 g (G). The weight of inflection (Wi) in studied birds were 912.67 g (L) and 1260.75 g (G). The time of inflection (ti) in birds was 8.51 months (L) and 11.00 months (G). The maximum growth rate in birds was 159.72 g/month (L) and 151.29 g/month (G). The coefficient of determination (R2) in both models included of very high category (0.80<R2<1.00) but the lower of standard error (SE) value showed in L model. It can be concluded that the non-linear regression of Logistic model can be used as BW predictors in mixed-sex Maleo birds.

Full textAbstract:
Computer simulation/optimization is widely applied to hot forming processes nowadays. A crucial point of any kind of computer simulation is the input data. There are implemented in all FEM codes some basic material database, but usually for limited materials and material states. As the input data decide about the output results quality, it is always necessary to pay attention, what are the simulation inputs. The best solution, but not always possible, is direct measurement of materials parameters for considered material and state. As this is in some cases not possible, materials data are searched in alternative ways. One possibility is survey of published data in literature. A reliability of published data is difficult to assess, as there are usually not available sufficient information about the material investigated in publications. Other possibility how to obtain material data nowadays is utilization of programs predicting material behavior on the basis of chemical composition. One of currently available software for material properties prediction is JMatPro. The program is able to calculate a broad range of properties and behavior with the use of established thermodynamics models on the basis of chemical composition and the initial state of the considered material state. There can be for example determined thermophysical and physical properties (from room temperature to the liquid state), time-temperature-transformation/ continuous-cooling transformation diagrams, stress/strain diagrams, proof and tensile stress, hardness, coarsening of γ and γ , and creep. The current paper is dealing with the simulation of hot forming of steam blade made of Ti-based alloy. As an input material data used for FEM simulation are conventionally measured data and data obtained from JMatPro. With the use of both material data sets, a sample component forming is simulated. The results obtained from both simulations are subsequently compared with the results obtained from physical forming of the sample component. Performance of both simulations is discussed here, taking into account results of physical forming results.

Full textAbstract:
A novel X-ray diffraction-based method and computer program X-TEX has been developed to determine the microstructure in individual texture components of polycrystalline, textured materials. Two different approaches are presented. In the first one, based on the texture of the specimen, the X-TEX software provides optimized specimen orientations for X-ray diffraction experiments in which diffraction peaks consist of intensity contributions stemming from grain populations of separate texture components in the specimen. Texture-specific diffraction patterns can be created by putting such peaks together from different measurements into an artificial pattern for each texture component. In the second one, the X-TEX software can determine the intensity contributions of different texture components to diffraction peaks measured in a particular sample orientation. According to this, peaks belonging mainly to one of the present texture components are identified and grouped into the same quasi-phase during the evaluation procedure. The X-TEX method was applied and tested on tensile-deformed, textured, commercially pure titanium samples. The patterns were evaluated by the convolutional multiple whole profile (CMWP) procedure of line profile analysis for dislocation densities, dipole character, slip systems and subgrain size for three different texture components of the Ti specimens. Significant differences were found in the microstructure evolution in the two major and the random texture components. The dislocation densities were discussed by the Taylor model of work hardening.

The aim: To elaborate the thermosemiotics of acute and chronic tonsillitis during exacerbation. Materials and methods: 48 patients with acute tonsillitis and 19 patients with chronic tonsillitis were examined during disease exacerbation. Thermographic examination was carried out by the medical thermometer TI-120. Statistical processing of data was carried out with computer program “Microsoft Excel” and “Statistica for Windows” v. 6.0, StatSoft Inc. (USA). Results: Symmetry, homogeneity and isotherm are normal thermographic features of the skin. Presence of hyperthermia in carotid triangle, on the palms were revealed in patients with acute tonsillitis. In chronic tonsillitis in the stage of exacerbation, a moderate overall «warming up» of the neck and projections of the submandibular lymph nodes was also observed. The average temperature indices of the knee joints were statistically significantly higher than the corresponding values in healthy people °C (P<0.01). Conclusion: Only in patients with acute tonsillitis clear strong positive correlation between the temperature of half of the submandibular area and warming in the center of the palm – r = 0.812 ... 0.859 (P<0.01) and in the middle of the tenar on the corresponding side – r = 0.790 ... 0.827 (P<0.01) was observed. Only in the case of chronic tonsillitis, in the stage of exacerbation, the temperature difference over the knees and the lower part of the femur is always greater than 0.5 ºC.

Medical records are files that contain records and documents including patient identity, examination results, treatment that has been given, as well as actions and other services that have been provided to patients. Data collection was carried out at the Regional General Hospital Dr. Rasidin Padang by recording data on inpatients who were discharged from the period March 01 - March 31, 2018, so that data were obtained as many as 251 patients with 103 beds. Then data processing was carried out using a computer with the Microsoft Excel application program. Furthermore, the data were analyzed and the results of health care statistical processing were presented in the form of tables and Barber Johnson charts. From the grouping of the most common diagnoses based on ICD-10 at the Regional General Hospital Dr. Rasidin Padang for the period March 01 - March 31, 2018, it was found that the most common code was code A91 as many as 21 patients with a diagnosis of Dengue Haemorrhagic Fever (DHF).Grouping the main diagnoses based on bowel movements in ICD-10 resulted in the highest frequency of diagnoses being BAB I (Certain infectious and paracitic diseases) and BAB XV (Pregnancy, chilbirth and pueperium) as many as 12.75% with a total of 32 patients each. The procedure grouping based on ICD-9 CM in RSUD dr. Rasidin Padang for the period March 01 - March 31, 2018 was SC with procedure code
74.99 as many as 14. Based on the DTD code and its definition, it is known that the most common diagnosis is DTD 032.1 (Dengue hemorrhagic fever) as many as 21 patients. In the RL4a Format table, it is known that the most age group as an inpatient at RSUD dr. Rasidin Padang for the period March 01 - March 31, 2018 is the age group 45 - 64 years as many as 70 patients with female gender as many as 37 patients and male as many as 33 patients, while based on the disposition died as many as 2 and live as many as 249. After data processing, it was obtained that the percentage of BOR at RSUD Dr. Rasidin Padang for the period March 01 - March 31, 2018 had not reached an efficient number because the value obtained was 26.65% or 27%, while the BOR efficiency rate was 60-85%. BTR is 2.44 or 2 times, because the calculation of the BTR number is per year, the BTR efficiency cannot be determined. TI is 9.33 or 9 days. This means that the TI value is not yet at an efficient point, because the TI efficiency value is 1 - 3 days.

This study adopted a multiple case-study approach to investigate incidents, their impacts on performance, and revenues in the telecommunications sector using data from Ghana. The study used open-ended qualitative interviews and document review methods. The study performed a thematic analysis with the Atlas TI software program to analyse the qualitative dataset. The findings resulted in a model dubbed the “Telecommunications Sector Incidents Framework”, which reveals that faulty hardware, end-of-system life, cell site congestion, power failure, microwave link failure, fibre failure, and Wi-Fi disconnection are among the incidents prevalent in the telecommunications sector. The framework also reveals that the incidents occur frequently, resulting in an average revenue loss of GH₵2 to 3 million ($182K to $273K) per month. Again, it reveals that employees become demoralized due to a lack of work-life balance, sleepless nights, frustrations, and undue pressure, which affects their productivity levels. With this framework, mobile network operators (MNOs) could get a better understanding of the incidents to keep their occurrences to a manageable level, create an exceptional customer experience by reducing churn, and increase revenues.

Full textAbstract:
The nanoelectronic modeling (NEMO) program is the result of a three-year development effort involving four universities and the former Corporate Research and Development Laboratory of Texas Instruments, now Applied Research Laboratory, Raytheon TI Systems, to create a comprehensive quantum device modeling tool for layered semiconductor structures. Based on the non-equilibrium Green function formalism, it includes the effects of quantum charging, bandstructure and incoherent scattering from alloy disorder, interface roughness, acoustic phonons, and polar optical phonons. NEMO addresses the diverse needs of two different types of users: (i) the engineer/experimentalist who desires a black-box design tool and (ii) the theorist who is interested in a detailed investigation of the physics. A collection of models trade off physical content with speed and memory requirements. Access to this comprehensive theoretical framework is accommodated by a Graphical User Interface (GUI) that facilitates device prototyping and in situ data analysis. We describe a hierarchical software design that allows rapid incorporation of theory enhancements while maintaining a user-friendly GUI, thus satisfying the conflicting criteria of ease of use and ease of development. The theory and GUI modules share data structures that define the device structure, material parameters, and simulation parameters. These data structures may contain general data such as integer and real numbers, option lists, vectors, matrices and the labels for both batch and GUI operation. NEMO generates the corresponding GUI elements at run-time for display and entry of these data structures.

Методом молекулярной динамики исследовалось плавление нанокластеров титана Ti(n = 3599, 28725, 97045) с различными скоростями их нагрева (от 0,1 до и 10,0 ТК/с). Молекулярно-динамическое моделирование проводили в программе LAMMPS на многопроцессорном компьютере. Использовался многочастичный потенциал межатомного взаимодействия. Кристаллическая структура нанокластера титана при нагреве переходит в жидкую фазу через образование системы атомов (островков) с упорядоченным локальным окружением вблизи температуры плавления. Появление последних обусловлено неравновесностью моделируемого процесса нагрева - система не успевает релаксировать к равновесному состоянию для заданной температуры. Под температурой плавления принималось среднее значение между температурами начала и окончания процесса фазового перехода. Температуре начала плавления соответствовало состояние завершения образования отдельных островков. При окончании плавления, наноструктура характеризуется полностью неупорядоченной структурой. Отмечается, что температура плавления увеличивается с ростом размера наночастицы и скорости её нагрева. При этом предельные температуры рассматриваемого фазового перехода (при N → ∞) существенно ниже температуры плавления массивного титана. The melting of titanium nanoclusters Ti (n = 3599, 28725, 97045) with different heating rates (from 0,1 to and 10,0 TK/s) was studied by the molecular dynamics method. Molecular dynamics simulation was carried out using the LAMMPS program on a multiprocessor computer. A many-particle potential of interatomic interaction was used. The crystal structure of a titanium nanocluster upon heating passes into the liquid phase through the formation of a system of atoms (islands) with an ordered local environment near the melting point. The appearance of the latter is due to the nonequilibrium of the simulated heating process - the system does not have time to relax to an equilibrium state for a chosen temperature. The melting temperature was taken as the average value between the temperatures of the beginning and finishing of the phase transition process. The temperature of the beginning of melting corresponded to the state of completion of formation of individual islands. At the end of melting, the nanostructure is characterized by a completely disordered structure. It is noted that the melting temperature increases with the size of the nanoparticle and the rate of its heating. The limiting temperatures of the considered phase transition (at N → ∞) are significantly lower than the melting temperature of the bulk titanium.

Abstract Objectives: This study was undertaken to evaluate the efficiency of two rotary nickel titanium instruments and hand instrumentation in removing gutta-percha and sealer from root canals. Study design: – 63 extracted human single rooted premolars were instrumented with K-files and filled using lateral compaction of gutta-percha (GP) and three different sealers. The teeth were randomly divided into three experimental groups of 21 specimens each. Removal of gutta-percha was performed with R-Endo retreatment files, Mtwo retreatment files and Hedstrom files. Time to reach working length and to eliminate filling material was also recorded. The specimens were sectioned for evaluation of the area of the remaining gutta-percha/sealer under stereomicroscope at 6X magnification. Photographs were taken for further analysis using computer image analysis program. The results were statistically analyzed using Analysis of variance (ANOVA) and Tukey’s honestly significant difference test. Results: The R-Endo retreatment system resulted in a smaller percentage of canal area covered by residual GP/sealer than in other groups, a significant difference was found between R-Endo and Mtwo group and between Hedstrom groups (P < 0.001). The Mean operating time was minimum with R-Endo group while it was found to be maximum with hand files. Conclusion: It was concluded that all test techniques left gutta-percha/sealer remnants within the root canal. The R-Endo retreatment files and Mtwo retreatment files system proved to be an efficient method for removing gutta-percha and sealer from single rooted premolars.

Full textAbstract:
Background: Small-field dosimetry remains an open challenge globally. Thus, it is crucial to consider adequate reference codes of practice for the performance of dosimetry. Furthermore, as part of good clinical practice, the implementation of new codes of practice implies the development of a dosimetry audit program. In this work, a pilot dosimetric audit protocol is established for measuring the absolute dose in water for small fields using micro-TLDs LiF:Mg,Ti dosimeters. Methods: The dosimeters were irradiated with a 6 MV X-ray beam in a linear accelerator. The TLDs were calibrated between 0.5 and 3 Gy for different field sizes. For audit, the TLDs were irradiated at 2 Gy for different circular field sizes. The proposed protocol consists of five TLD dosimeters forming a cross with a marked radiochromic film to identify the position of the central dosimeter during irradiation. Only the dosimeter measurement in the center of the field is used. Results: It was found that the percentage difference between the measured dose and the prescribed dose (2 Gy) for irradiation in circular fields is less than 3%. Conclusions: A pilot dosimetric audit was carried out using the proposed protocol over a linear accelerator using small circular collimator photon beams.

Study purpose. Physical inactivity among school students was an existing health issue over the past decade. This became more alarming when the world was hit by the COVID–19 pandemic. Movement restriction that results temporary school closure significantly affect students’ physical activity participation. Therefore, strategies and practices to improve active play engagement as well as to counteract its negative health-related effects on students were widely implemented by teachers and administrators in school upon its re-opening. Numerous articles have been published on the effectiveness of school-based interventions during the COVID-19 pandemic, but there is still a lack of a review paper that deals with the identification of patterns and trends about school practices in this area. Hence, this paper intends to generate impressions and identify concepts within the published articles during 2021 to 2023. Materials and methods. Selected articles for this study were collected from the following databases: SCOPUS, Sage, ProQuest, Academic Search complete, Science Direct. Computer-assisted qualitative data analysis (ATLAS ti. 23) guided the comprehensiveness of this review. Study findings were generated and presented through quantitative and qualitative lenses. Results. Four central themes were identified: 1) Alternative Physical Education – modifying traditional physical education subject; 2) Physical literacy focus – approach anchored to multi-dimensional foundation in physical activity engagement 3) Web-based intervention – virtual and cyberspace approach and 4) Needs–based intervention – focusing on integration of participants’ attributes and specifically designed program. Conclusions. The structure of strategies conducted by schools were greatly affected by the current community health status. Findings of this study will serve as a reference for designing future intervention approach to address the sedentary lifestyles of young populations associated to specific community health and other related issues.

Con el objetivo de interpretar la experiencia de padres de familia y profesores de educación preescolar y primaria sobre el aprendizaje de los estudiantes de educación primaria en la nueva modalidad desde la que se desarrolla el currículo, los retos que enfrentan los padres de familia en su nuevo rol como docentes en casa durante el confinamiento por COVID-19. Se utilizó un enfoque cualitativo con método fenomenológico. Los datos se obtuvieron de entrevistas en profundidad a 21 profesores de preescolar y primaria y 56 padres de familia. El análisis de datos se realizó con el software Atlas ti. Los resultados indican que los padres de familia enfrentan dificultad para ofrecer apoyo pedagógico a sus hijos, por lo que demandan mayor acompañamiento y preparación pedagógica por profesores, lo que implica cambios en la organización escolar y adecuación al currículo según las características del entorno y necesidades de formación de los alumnos. En esta modalidad los profesores son reproductores del currículo, por ello los alumnos están desmotivados para aprender, ya que el currículo no responde a sus intereses y necesidades.
Abstract
The objective of this research is to interpret the experience of parents and, preschool and elementary school teachers regarding elementary school students' education in the new modality from which the curriculum was developed, facing the challenges encountered by tutors in their new role as teachers at home during the COVID-19 confinement. The study used a qualitative approach with a phenomenological method. Data were obtained from in-depth interviews applied to 21 preschool and elementary school teachers and 56 parents. Data analysis was performed with ATLAS.ti software. The results indicate that parents find it difficult to offer pedagogical support to their children, so they demand greater pedagogical support and preparation by teachers, which implies changes in the organization of the school and adaptation of the curriculum to the characteristics of the environment and the educational needs of their students. In this modality, teachers replicate the curriculum, consequently students are unmotivated to learn since the study program is not responsive to their interests and needs.

Full textAbstract:
We present a game-theoretic treatment of the so-called TEM model which leads to new results in the area of time-discrete dynamical games. The presented TEM-model describes the economical interaction between several actors (players) who intend to minimize their emissions (Ei) caused by technologies (Ti) by means of expenditures of money (Mi) or financial means, respectively. The index stands for the ith player, i=1,…,n. The players are linked by technical cooperations and the market, which expresses itself in the nonlinear time-discrete dynamics of the Technology-Emissions-Means-model, in short: TEM-model. In the sense of environmental protection, the aim is to reach a state which is mentioned in the Kyoto Protocol by choosing the control parameters such that the emissions of each player become minimized. The focal point is the realization of the necessary optimal control parameters via a played cost game, which is determined by the way of cooperation of the actors. In application to the work of G. Leitmann [1974], but not regarding solution sets as feasible sets, the τ-value of S. H. Tijs and T. S. H. Driessen [1986] is taken as a control parameter. This leads to a new class of problems in the area of 1-convex games. We want to solve the problem by a non-cooperative and cooperative treatment. We prove that the core which is gained by cooperation of the players is nonempty and can be used as feasible set for our control problem. With this solution a reasonable model for a Joint-Implementation process is developed, where its necessary fund is represented by the non-empty core of the analyzed game. Steering with parameters of this feasible set, the TEM-model can be regarded as a useful tool to implement and verify a technical Joint-Implementation Program. For the necessary data given to the Clearing House () we are able to compare the numerical results with real world phenomena.

The morphology ZrO2-Ti composites depends on used powders substrates, methods of forming and sintering conditions. In this study a composite from the nanosize ZrO2 powder stabilized by 3 mol% Y2O3 and 3 vol. % Ti powder with particle size about 15 μm was prepared. A composite material was formed by uniaxial pressing. Sintering process was conducted in an argon atmosphere at 1300°C with retention time 2h. The selected physical properties of the green body and sintered ZrO2-Ti composites were determined by Archimedes method. The microstructural characterization was carried out using the x-ray diffraction and the scanning electron microscope (SEM) with EDS analysis. Stereological analysis by using computer programs was supported. The SEM observation and EDS analysis of the cross-section of the samples confirmed that the Ti particles are distributed homogenously in analysed areas. The EDS analysis revealed partial solution of titanium in ZrO2 matrix. Moreover, the x-ray diffraction exposed the existence of tetragonal zirconium oxide and titanium or a new phase from Ti-Zr-O system. The stereological analysis showed similarity between the starting particles of Ti powder and particles of titanium in the composite matrix.

Editors note: Contemporary statistics courses at both the secondary and collegiate levels expect students to interact with data and to discover and confirm ideas with simulations. Traditionally this objective has been accomplished with computer programs. However, students can perform many of these simulations on the home screen of a graphing calculator. Such an intimate interaction with the process of simulation may help develop a better understanding of the underlying concepts. Gloria Barrett, a teacher at the North Carolina School of Science and Mathematics and author of Statistics with the TI-83 (Meridian 1997), has convinced many of us of the power of this approach.

Several researchers have developed finite element analysis (FEA) models on dental implants; however, few have used it to investigate the effects of nanosurface treatment on the cell-implant interface. For cell proliferation and differentiation are believed related to the physical stimulations of modification surfaces. In the present study, the cell adhesion affected by mechanical stimulation from substrate was evaluated by culturing the MG-63 osteoblast-like cells on Ti materials with different chemical composition using computer-aided programs. Three types of surfaces were made by mechanically abraded, anodized and anodized following with hydrothermal treatment on Ti substrates. The cell adhesion behavior was promoted because the physical stimulation of specific surface topography provided cells mechanical external forces. The finite element analysis (FEA) was used to investigate the deformations stresses which cells were suffered on these 3 different modifications surfaces. Results indicated that cells in the HTT group were received larger stimulation of deformations and stresses than the control group (P > 0.01). This confirmed that the superior cell proliferation and differentiation resulted from the specific roughly surfaces of HYT surface for implants.

This symposium is a follow-up to a sumposium held at last year's HFS meeting. “Training Technology in the 1990s: Development, Application and Research Issues.” Representatives from the three military services discussed how many facets of training technology would affect current and future design applications and research issues relevant to military training systems. Two topics from that session (artificial intelligence and embedded training) and one other topic (computer-based authoring of technical information) have beer selected for in-depth discussion. Each technology is computer-based and has been exploited to only a limited degree. The object of this symposium is to provide a focus for describing how the three technologies are important for emerging and future training systems. For example, nearly all technical information (TI) for maintaining and operating weapon systems in the field is currently paper-based but the Department of Defense is committed to transitioning to electronic delivery of TI within the next decade. Many R&D issues must be resolved in the interim. Similarly, the technologies of embedded training and artificial intelligence have considerable potential for future training systems once a number of R&D issues are successfully addressed. All three services have on-going research and development programs for the technologies covered in this sumposium. Each topic is presented by representatives from at least two military behavioral laboratories: for computer-based authoring, Naval Training Systems Center (NTSC), Naval Personnel Research and Development Center (NPRDC) and Army Research Institute (ARI); for artificial intelligence, Air Force Human Resources Laboratory (AFHRL) and NTSC; and for embedded training, NTSC and ARI. The goals of the symposium are: (1) to make clearer the most pressing R&D issues associated with these technologies, and (2) to discuss how future training systems might incorporate them.

Full textAbstract:
Assuming elliptical wavefronts, we reformulate refraction theory for transversely isotropic (TI) media based on the use of the auxiliary angle, α, which is intermediate between the phase angle, θ, and the group angle, ϕ. When considering the application of stretching to transform elliptically anisotropic media into isotropic media, the auxiliary angle is a natural one to use because both θ and ϕ → α under such stretching. Our present formulation for TI media makes the assumption of elliptical anisotropy, which is valid generally for SH-waves but only as a special case for P-and SV-waves, where, in the SV case, the only possible ellipses are circles. Nevertheless, the theory has useful applications for P-waves over limited ranges of propagation direction (e.g., in the short-spread approximation). Our formulation provides explicit results for all angles of incidence and for what we term an angular unconformity between two TI media, that is, for all orientations of the axes of symmetry for each of the media, and for all orientations of the interface, assuming these two axes and the interface normal to lie in the same vertical plane. Our conclusions have been verified by showing that the phase angles and phase velocities of the incident and refracted waves obey Snell's law across the interface. We also demonstrate, using auxiliary angles, that the description of refraction between elliptically anisotropic media by stretching the media to make them isotropic, then applying isotropic refraction, is also valid for our general angular-unconformity case. However, both stretching (1D) and either scaling (2D) or shearing must be applied correctly and separately to the two media. The refraction algorithm developed from this theory and another developed by Byun in terms of phase-velocity theory are currently the only published noniterative algorithms known to us for refraction across an angular unconformity where the axes of anisotropy are parallel neither to each other nor to the interface. Based on this theory, we have developed a demonstration program, AUXDEMOC, that computes the refracted-ray angles for any combination of parameters by the two equivalent methods: (1) anisotropic refraction and (2) stretching plus isotropic refraction.

We have derived elemental abundances of eight RV Tauri-type post-asymptotic giant branch stars: AR Sgr, CE Vir, DY Aql, HP Lyr, SS Gem, SZ Mon, TT Oph, and UZ Oph. The abundance analysis of these luminous stars is based on the high-resolution (R ≈ 55 000) optical echelle spectra obtained with the 2.1 m Struve reflector telescope and the CCD-equipped Sandiford Cassegrain echelle spectrograph at the McDonald Observatory. Standard 1D local thermodynamic equilibrium analysis provides a fresh determination of the atmospheric parameters and elemental abundances for 17 species including C, Na, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Y, and Nd. Then, the computed up-to-date abundances are used to investigate FIP in the program stars, as seen in the Sun and sun-like stars. Also, we scrutinize their behavior for dust–gas separation as an alternative mechanism to the FIP. For the first time, we provide atomic line lists with up-to-date atomic data employed in the analysis for AR Sgr, HP Lyr, SZ Mon, TT Oph, and UZ Oph.

Full textAbstract:
A fretting fatigue crack initiation mechanism (number of cycles, location and orientation angle) using critical plane based parameters has been addressed by several researchers. There are several process variables that can affect these parameters and thereby the prediction of fretting fatigue crack initiation behaviour. Effects of two such parameters, viz. process volume and the coefficient of friction, were investigated in this work. Fretting fatigue experiments with a titanium alloy were conducted with different contact pad geometries. Finite element analysis (FEA) was used to obtain a stress state in specimens for the experimental conditions used during fretting fatigue tests. Analysis was carried out for two values of the coefficient of friction, thereby providing a framework for calculation of several critical plane based multiaxial fatigue parameters for different process volumes. A program was developed to compute these multiaxial fatigue parameters from the FEA data for different values of process variables. It was observed that parameters for cylindrical pad geometries with no singularity-type behaviour were inversely proportional to the size of process volume and directly proportional to the coefficient of friction. There was no change in the predicted orientation of the primary crack for this geometry, due to variations in these process variables. Parameters for flat-pad geometries with behaviour approaching that of a singularity were also inversely proportional to the size of process volume, but the coefficient of friction had a minimal effect on their values. Predicted orientation of the primary crack for these geometries changed slightly when the process volume increased from that of a grain size of the tested material to a larger size, and then did not change with the increase of process volume size. Overall, the effect of these process variables on the critical plane based parameters was similar in all five contact geometries used in this study, when the scatter in fatigue data is kept in mind. Finally, the modified shear stress range parameter satisfactorily predicted the crack initiation location, orientation angle and number of cycles to fretting fatigue crack initiation independent of the contact geometry for a given process volume size and coefficient of friction.

As vital infrastructures, high-speed railways support the development of transportation. To maintain the punctuality and safety of railway systems, researchers have employed manual and computer vision methods to monitor overhead contact systems (OCSs), but they have low efficiency. Investigators have also used light detection and ranging (LiDAR) to generate point clouds by emitting laser beams. The point cloud is segmented for automatic OCS recognition, which improves recognition efficiency. However, existing LiDAR point cloud segmentation methods have high computational/model complexity and latency. In addition, they cannot adapt to embedded devices with different architectures. To overcome these issues, this article presents a lightweight neural network EffNet consisting of three modules: ExtractA, AttenA, and AttenB. ExtractA extracts the features from the disordered and irregular point clouds of an OCS. AttenA keeps information flowing in EffNet while extracting useful features. AttenB uses channel and spatialwise statistics to enhance important features and suppress unimportant ones efficiently. To further speed up EffNet and match it with diverse architectures, we optimized it with a generation framework of tensor programs and deployed it on embedded systems with different architectures. Extensive experiments demonstrated that EffNet has at least a 0.57% higher mean accuracy, but with 25.00% and 9.30% lower computational and model complexity for OCS recognition than others, respectively. The optimized EffNet can be adapted to different architectures. Its latency decreased by 51.97%, 56.47%, 63.63%, 82.58%, 85.85%, and 91.97% on the NVIDIA Nano CPU, TX2 CPU, UP Board CPU, Nano GPU, TX2 GPU, and RTX 2,080 Ti GPU, respectively.

The main purpose of this study was to come up with a general description and relationship among the extent of services, quality of life and satisfaction of senior citizens in Bacolod city. The areas of services include; health social access to public transport, utility discount and mandatory Philhealth coverage. Areas in the quality of life includes; health status, financial security, organizational affiliation, household relations and access to senior citizens’ benefits. Areas on satisfaction includes; appreciation of good health, social support, emotional security, contentment and leisure and activity. The study employed the descriptive, comparative and relational analytical schemes in coming up with a general description, comparison and relationship among the selected variables. The mean, t-test and Pearson Product Moment of Correlation formula was used. Findings of the duty revealed that senior citizens were adequately provided with all these services particularly on health, social public transport, utility discount and mandatory Philhealth services. They are experiencing quality living with regards ti their relationship in their household and access to Philhealth benefits. However, findings showed that they are not adequately contented with regards to health condition and financial security. They were having high level of satisfaction on the aspect of social support, emotional security, and leisure activities. Moreover, study showed that there was significant relationship between services and quality of life of senior citizens. Likewise, a significant relationship between the services and satisfaction of senior citizens and a significant relationship between the satisfaction and quality of life of senior citizens has existed. The study concluded that on services, although the extent was not at its highest degree of contentment to the services but senior citizens were contented of all the services provided to them. On quality of life, senior citizens were not fully contented and happy about the quality of life they were experiencing to note that a moderate extent on contentment was perceived by the senior citizens. On satisfaction, senior citizens degree of satisfaction was high considering that majority of life satisfaction was perceived by them to be high particularly in social, emotional, leisure and contentment. It was concluded further that senior citizens were not fully satisfied or contented about their health condition. The study highly recommends that medical programs/project shall provide greater emphasis on the following; married, low income, rural areas, male, without college degree senior citizens. Social services programs/project shall provide greater emphasis on the following; married, low income, rural areas, without college degree. Access to public transport programs/project shall provide greater emphasis on the following; married, low income. Utility discount programs/project shall provide greater emphasis on the following; married, without college degree, low income and leisure activity with greater emphasis on married, without college degree and low income senior citizens

Monitoring environmental conditions is an important application of cyber-physical systems. Typically, the monitoring is to perceive surrounding environments with battery-powered, tiny devices deployed in the field. While deep learning-based methods, especially the convolutional neural networks (CNNs), are promising approaches to enriching the functionalities offered by the tiny devices, they demand more computation and memory resources, which makes these methods difficult to be adopted on such devices. In this article, we develop a software framework, RAP , that permits the construction of the CNN designs by aggregating the existing, lightweight CNN layers, which are able to fit in the limited memory (e.g., several KBs of SRAM) on the resource-constrained devices satisfying application-specific timing constrains. RAP leverages the Python-based neural network framework Chainer to build the CNNs by mounting the C/C++ implementations of the lightweight layers, trains the built CNN models as the ordinary model-training procedure in Chainer, and generates the C version codes of the trained models. The generated programs are compiled into target machine executables for the on-device inferences. With the vigorous development of lightweight CNNs, such as binarized neural networks with binary weights and activations, RAP facilitates the model building process for the resource-constrained devices by allowing them to alter, debug, and evaluate the CNN designs over the C/C++ implementation of the lightweight CNN layers. We have prototyped the RAP framework and built two environmental monitoring applications for protecting endangered species using image- and acoustic-based monitoring methods. Our results show that the built model consumes less than 0.5 KB of SRAM for buffering the runtime data required by the model inference while achieving up to 93% of accuracy for the acoustic monitoring with less than one second of inference time on the TI 16-bit microcontroller platform.
