The physics remote laboratory: Implementation of an experiment on Standing Waves

There always have been some hurdles when it comes to the adequate use of didactical experimental activities in science education, such as the lack of proper training, insufficient time, and inadequate infrastructure. At this very moment, the pandemic has taught us that there may be also circumstances in which the traditional laboratory and the traditional activities are just not possible, thus online operable experiments might constitute a viable alternative for the practical lessons in higher education. In this paper, we discuss the development and the implementation of a remote-controlled didactical experiment on Standing Waves largely used in the physics basic program offered to the engineering courses. The development has combined applied knowledge from different areas, i.e. electric and electronics engineering, and computer science. In order to ascertain the experiment consistency, we have gathered data from the wave propagation speed and from the corresponding tension applied to the string and performed a χ-square linear fit in order to determine the correlation between the logarithm of both parameters. The experiment was successfully implemented and has been accessed by hundreds of different users from more than 30 different countries ever since. It has also been largely employed in practical activities at the university and has shown no significant signs of instability. It exhibited a total latency time inferior to 0.8 seconds on average and the results drawn from data it provides have shown to be accurate, within less than 0.8% of deviation with respect to the theoretical results.

Client satisfaction to methadone maintenance treatment program in Myanmar

Background To tackle the long-standing opioid misuse problem, Myanmar introduced the methadone maintenance treatment (MMT) program in 2006, starting with 260 clients. Since then, the program has been expanded across different geographical sites in the country. This study was done in 2017 to explore the treatment satisfaction of the clients towards the MMT program. Method A total of 210 clients with a minimum of six-month treatment history enrolled in five MMT program sites across Myanmar were recruited through stratified random sampling. Administering the Verona Service Satisfaction Scale for Methadone-Treatment (VSSS-MT), this study assessed the satisfactory responses under three categories viz., 1) clinic staff professional skills; 2) basic drug intervention; 3) specific intervention (individual rehabilitation and psychotherapy). Results The majority (89%, n = 186) of the respondents were satisfied with the current MMT program. Specifically, 89.5% (n = 187) were satisfied with the clinic staff professional skills category, 91.9% (n = 192) with the basic program intervention and 74.6% (n = 156) with specific interventions. Among the respondents, treatment satisfaction with the MMT program was higher (p < 0.05) in those (i) with a higher quality of life score in physical, psychological, social and environmental categories, ii) who were satisfied with their current marital and leisure status, and those iii) who consumed alcohol. Results from stepwise binary logistic regression showed alcohol consumption and physical health status had a significant association with MMT treatment satisfaction. Conclusion Treatment satisfaction of the clients, in general is high. However, the lower percentage of satisfied clients (74.6%) for the specific interventions category compared with 89.5 and 91.9% respectively for staff and basic drug management categories highlights the need for improvement in this category for overall enhancement of the MMT program.

A Multivariate Regression Model for Predicting the 28days Flexural Strength of Lime-Cement Concrete Beam

In this study, a multivariate regression model for predicting the 28days flexural strength of lime-cement concrete prototype beam was developed. The response function is a multivariate function of the proportions of the component materials of concrete. A total of twenty mix ratios, consisting of water, Portland cement, hydrated lime, river sand and granite chipping were used in the prediction process. The first ten mix ratios were used for model development while the remaining ten mix ratios were used as check points for model validation. The model developed was tested for adequacy at 95% level of confidence using the t-statistic. Calculated t-value was -1.3342 and this was less than the critical t-value of 2.2622. Thus, the model was found to be adequate. An average percentage difference of 14.303% was observed between the model prediction and the experimental values. A visual basic program using the Visual studio 2015 software was developed based on the regression model. It was invoked to quicken the process of selecting the mix ratios of the component materials corresponding to any desired flexural strength value that falls within the region of experimentation and vice versa Keywords— Concrete , flexural strength, multivariate regression model, response function.

USLUGE HUMANITARNIH ORGANIZACIJA

The author of this work point to the fact that humanitarian organizations are the part of non-profit sector which are established and work in order to achieve general welfare of the individuals, particular social groups or society in whole. What is important to emphasize is that they belong to so called, voluntary sector whose work is transparent and is based on the laws of the country in which they operate. Each humanitarian organization has its own strategic plan, which as a written document, is aimed at achieving basic program goals. The monitoring of the implementation of adopted projects and the control of the management process are the mandatory (final) phases of their work. Humanitarian organizations as the part of non-state sector today play increasing role in offering services in various fields of social life to a wide range of beneficiaries. 0 It is interesting to note that these organizations are more present in developing countries and the countries in transition, particularly in the field of social services. The grounds for this situation can be found in the decentralization process and new, modified apprehension of the role of the state in the work of the growing number humanitarian organizations and movements. Namely, decentralization allows the delegation of powers and tasks from the central to local government levels and this is the main reason for rapid expansion of non-government sector on the global level and increasing participation of non-government sector in service providing.

Analisa Model Evaporasi dan Evapotranspirasi Menggunakan Pemodelan Matematika pada Visual Basic di Kabupaten Maros

The approach to calculating evaporation and evapotranspiration, both potential and actual, varies widely. The models used to estimate the amount of evapotranspiration, particularly at the Maros Climatology Station, Maros Regency, South Sulawesi. Evaporation models use the Penman, Priestley, Bruin, and Valiantzas models while evapotranspiration models use the Penman, Hargreaves, Jensen-Haise, Penman-Monteith, Radiation, Turc, and Makkink models, where all of these methods use climate data, such as are the minimum temperature (Tn), maximum temperature (Tx), air temperature (Ta), average humidity (RH), rainfall (R), duration of sun exposure (SS), and maximum wind speed (U) in calculations using Visual basic program in Microsoft Excel in the form of code. Thus, it is necessary to conduct an analysis of the suitability of the model to the results of the observations in order to find out which model is suitable according to the results of the largest coefficient of determination (R2). Based on the results of the model suitability analysis, a selected model was obtained, namely the Valiantzas model with a value of 0.980 in the evaporation calculation and the Jensen-Haise model, namely 0.889.

Smart Navigation with Static Polygons and Dynamic Robots

Due to the last increase in data and information technology, the need to use robots in many life areas is increased. There is a great diversity in this field, depending on the type of task required, as the robot enters the parcels of air, land, and water. In this paper, a robot's mission designed to move things is concentrated, relying on line-tracing technology that makes it easy to track its path safely, the RFID is distributed in its approach. When the robot reads the RFID tag, it stops until it raises the load from above, the robot continues its path toward the target. When an obstacle obstructs the robot path, the robot deviates and returns after a while to its previous approach. All this technology is implemented using a new algorithm which is programmed using the visual basic program. The robot designed to transfer the stored material is used according to a site known as an identifier that is identified by the RFID value, where the robot is programmed through a microcontroller and a unique store program that determines the current location and the desired location, then is given the task for the robot to do it as required. The robot is controlled using an ATmega controller to control other parts connected to the electronic circuit, the particular infrared sensor, and ultrasound to avoid potential obstacles within the robot's path to reach the target safely. In addition to this, the robot is made up of an RFID sensor to give unique to each desired target site. Through the console, it is possible to know the link indicated by the target. The H-bridge is also used to obtain a particular command and guide the robot as needed to move freely in all directions and a DC motor which is unique for moving wheels at the desired speed, and Bluetooth for programmable and secure wireless transmission and reception with all these parts through a unique program that also uses application inventory. The robot has proven to be a great success in performing the required task through several tests that have been practically performed.

HMCA-Contour: A Visual Basic Program Based on Surfer Automation for Soil Heavy Metal Spatial Distribution and Contamination Assessment Mapping

Soil heavy metal contamination has become a major concern in many parts of the world. Grasping the spatial distribution patterns of heavy metals and evaluating soil heavy metal contamination are of great significance to policy makers for land use planning and pollution identification. However, these processes usually involve repetitive calculation and plotting, which are time-consuming and laborious, especially in a geochemical survey. In this paper, HMCA-Contour, which is a program written in Visual Basic based on Surfer 13.0, has been designed to simplify the pollution indices recalculation and plotting routines. This software is comprised of three functions, i.e., data processing, plotting, and template setting. With user-friendly interfaces, the user can easily and efficiently calculate pollution indices and generate batch publication-quality maps of heavy metal spatial distribution and pollution levels. To demonstrate the advantage of HMCA-Contour, a case study from the Gaerqin Mine area is used in this paper. HMCA-Contour, as a brand new software, is promising and will become a useful tool for environmental management.
