COMMON FRAMEWORK: A HYBRID APPROACH TO INTEGRATE CROSS-PLATFORM COMPONENTS IN MOBILE APPLICATION

Collaboration in research is essential for saving time and money. The field of high-energy physics (HEP) is no different. The higher level of collaboration the stronger the community. The HEP field encourages organizing various events in format and size such as meetings, workshops and conferences. Making attending a HEP event easier leverages cooperation and dialogue and this is what makes Indico service defacto a community standard. The paper describes HEPCon, a cross-platform mobile application which collects all information available on Indico and makes it available on a portable device. It keeps most of the data locally which speeds up the interaction. HEP-Con uses a shared code base which allows easy multiplatform development and support. There are iOS and Android implementations available for free download. The project is based on C# and we use the Xamarin mobile app technology for building native iOS and Android apps. SQLite database is responsible for retrieving and storing conference data. The app can be used to preview data from past CHEP conferences but the tool is implemented generic enough to support other Indico events.

The ExasSMR project focuses on the exascale application of single and coupled Monte Carlo (MC) and computational fluid dynamics (CFD) physics. Work is based on the Shift MC depletion, OpenMC temperature-dependent MC, and Nek5000 CFD codes. The application development objective is to optimize these applications for exascale execution of full-core simulations and to modularize and integrate them into a common framework for coupled and individual execution. Given the sheer scale of nuclear systems, the main algorithmic driver on the CFD side is weak scaling. The focus for the first four years of the project is on demonstrating scaling up to a full reactor core for high-fidelity simulations of turbulence. Full-core fluid calculations aimed at better predicting the steady-state performance will be conducted with a hybrid approach in which large eddy simulation is used to simulate a portion of a core and unsteady Reynolds-averaged Navier-Stokes handles the rest. This zonal hybrid approach provides an additional scaling dimension besides the number of assemblies. The present manuscript focuses on performance assessment using assembly-level simulations with Nek5000. We discuss the development of two benchmark problems: a subchannel (single-rod) problem to assess internode performance and a larger full-assembly problem representative of a small modular reactor (SMR). We note that current SMR assemblies are considerably simpler than pressurized water reactor assemblies since they contain no mixing vanes. This feature allows for considerable reduction in the degrees of freedom required to simulate the full core. We discuss profiling and scaling results with Nek5000, describe current bottlenecks and potential limitations of the approach, and suggest optimizations for future investigation.

The benefits of the BYOD (Bring Your Oun Device) approach is describes. This approach contributes to greater efficiency of business processes and economy of the enterprise budget. The necessity of focusing on the problem of information security is substantiated. As a solution, a mobile application is proposed that allows to identify the user and distribute security policies to the device. The following describes the problems that arise in the process of solution – problems of transferring data from a mobile device to the storage, the problem of centralized storage of incoming data, assignment of geolocations available for working with the application, and a problem of cross-platform. Further, the task is formulated – to design and develop a universal solution to these problems, since there is no single, universally accessible solution that would satisfy all the described requirements. The next part of the article describes the model of the proposed system, gives its general description in a formalized and graphical form. The article also provides an image and description of the system architecture, consisting of three main parts: IOS client, Android client and server. The advantages of the developed client-server architecture are highlighted: security and centralized access to data. The architecture of each individual part is described with a specification and justification for the choice of libraries and technologies used. The following describes the operation of the system, presents a sequence diagram of the client requests during authorization and receiving a set of policies for a new user, and BPMN diagram of the business process for obtaining Android agent data. Thus, the resulting solution will reduce the cost of administration of mobile devices in a corporate environment.

The Laboratory information system is one of the information systems that was built by the BSTI of Polytechnic Caltex Riau to provide information about laboratory lending. This system is also being intended to the person who is in charge of approving laboratory lending such as the head of the laboratory, and laboratory assistant in case of monitoring some of the laboratories that are lent. However, the features provided by this information system are not enough to support the process of laboratory lending. Therefore, a mobile application with the quality of Cross-Platform was built, in other words, it can be used on iOS and Android platforms. One of the technologies that can be used to build a cross-platform application is the React Native. This application was built with a prototype method that is used to get more perspective points from users with interviews and can simplify the development of this application to be effective. This application was developed with Laravel, Firebase Authentication, and MySQL. Because there are several problems with the old system, an application that offers several solutions consists of avasisten instruktur laboratoriumbility in the lending laboratory, receiving legal paper of laboratory lending, and receiving notification were developed in this study. The main feature provided in this application is the evidence letter of laboratory lending that doesn’t have to be printed so that can reduce paper usage. As a result, 94.1% of respondents stated that this application’s features can run well and make it easy for college students to propose laboratory lending.

Abstract Background. There is little evidence available to better understand how mobile health application technology on mother and child health is designed. This study aimed: (a) to explore community health worker (CHW)/cadre and mothers’ activities information related with Posyandu, as well as inputs and feedbacks in developing the Posyandu mobile application, (b) to compare between training and implementation phases of the application, (c) and to see the potential use of the Posyandu mobile application in the country. Method. Using a hybrid method in which the action research principles and qualitative-quantitative methods were synergistically combined for the end users. The study was conducted in Pasawahan sub-district, Purwakarta, Indonesia from 2017 to 2019. Content analysis, coding and categorizing were done using NVivo 12 Pro for the transcribed data. Wilcoxon Test (2018 and 2019) was conducted using STATA 15 Special Edition. Results. (1) the use of CHW notebook for data entry in Posyandu information system book made a long delay in the data reporting process, thus, the development of mobile application would be necessary, (2) there were significant differences of CHW’s knowledge (p=0.000) and skills (p=0.0097) on training (2018) and Posyandu phases (2019), (3) As many as 964 posyandu are registered to Posyandu mobile application from almost all provinces in Indonesia. Conclusions. The 3-years hybrid approach suggests the crucial phases to build a mobile application in a more user-friendly manner that can replace the CHW’s old-fashion book use, and that it is promising for national use.
