Online medical consultation: covid-19 system using software object-oriented approach

The internet has been a source of medical information, it has been used for online medical consultation (OMC). OMC is now offered by many providers internationally with diverse models and features. In OMC, consultations and treatments are available 24/7. The covid-19 pandemic across-the-board, many people unable to go to hospital or clinic because the spread of the virus. This paper tried to answer two research questions. The first one on how the OMC can help the patients during covid-19 pandemic. A literature review was conducted to answer the first research question. The second one on how to develop system in OMC related to covid-19 pandemic. The system was developed by Visual Studio 2019 using software object-oriented approach. Online expert review was conducted within 6 experts from health and academic industry to verify the model. Also, the system was validated by 11 users from heath and academic industry to confirm its usability. The statistical package for social science (SPSS 22) was used to analyze the collected data. The result of expert review confirmed that covid-19 system can help the patients. Also, the validity of the system was confirmed by 11 users from health and academic industry.

Object-Oriented Metrics for Quality Improvement of Object-Oriented Software

Software metric is a computation of characteristics of a programming applications for quality enhancement. Software metrics are used to access the productivity and efficiency of a software product. These are helpful to understand the technical procedure used to create software. Software metric enables software engineers to assess software quality, software process improvement, monitoring and controlling of software. Object-Oriented Software Development is related to real-world objects and their characteristics creation instead of working in software applications. Class Objects have their own internal data structure, which defines their data and methods. Object-Oriented design restrained all the properties and worth of software that is allied to any large or small project. Object-Oriented metric is a measurement term in which a Object-Oriented Software holds features. These are guidelines that give an indication of the progress that a project has made quality.

Object-component development of changeable software systems

Complementary limitations of both Software Product Lines industrial technologies and Lavrischeva – Grishenrko object-component method concerning changeable software development are elicited such as the lack of formalisms for program assets building and ill predictability of this build features. To cope with the limitations universal Model of Software Family Variant Features is proposed expanding its tradi-tional feature model for basic development artifacts. For assets being considered as reusable Components final Changeable Software Object-Component Model is elaborated including the universal model above being adjusted as Software Variability Object-Component Model. The Algebra is depicted for the operations of both the Components configuring and data types transforming over their interaction within changeable software system. These operations are proposed to incorporate into the target process for Changeable Software Family proactive and informed Variability management being represented with its technological chart. The process proposed composes the functions for variability Planning, Implementing and Control as well as Family model/consist Evolving up to the Control results. The functions listed are performed within common information environment structured accordingly to Variant Features Model or its object-component adjustment. Trial software tool for configuring Components in the above process is probed. The usage is depicted of both the framework proposed and this tool over technological lines being implemented in Software Systems Institute of NAS of Ukraine Instrumental-technological complex for changeable software configuring from the components.

Analisa Pergeseran Magnetic Domain Wall pada Lapisan Tipis Free Layer Co/Pd terhadap Pengaruh Dimensi Sampel (Halaman 55 s.d. 58)

Telah dilakukan analisa pergeseran magnetic domain wall pada lapisan tipis free layer Co/Pd dengan menggunakan software Object Oriented Micromagnetic Framework (OOMMF) berdasarkan persamaan Landau-Lifshitz Gilbert (LLG). Analisa dilakukan pada ukuran 100x100 nm dengan memvariasikan ukuran ketebalan yaitu 1 nm, 3 nm, dan 5 nm. Dengan pemberian medan eksternal dari arah sumbu (+)z, magnet saturasi dicapai pada 31.290 Oe untuk ketebalan 1 nm, 30.940 Oe pada ketebalan 3 nm, dan 30.660 Oe pada ketebalan 5 nm. Selanjutnya dilakukan analisa dengan variasi ukuran pada ketebalan 5 nm yaitu 100x100 nm, 300x100 nm dan 500x100 nm. Magnet saturasi pada ukuran 300x100 nm dicapai pada pemberian medan eksternal sebesar 30.970 Oe dan magnet saturasi pada ukuran 500x100 nm dicapai pada pemberian medan eksternal sebesar 31.040 Oe.

Hybrid Modeling

Enterprise Interoperability can be identified on cultural, rule, process, data, software, object, social network, services, knowledge, electronic ID, cloud, and ecosystem level, whereas the challenge is the conceptual integration across those layers in a flexible way. Meta Modeling as a concept is a proven technology to enable such conceptual integration for both machine computation and human-oriented interpretation for information value creation. Hybrid Modeling is a realization approach to merge different meta models and hence enable the interoperability between conceptual models. Stability is provided by the meta modeling platform whereas flexibility is ensured by hybrid modeling via a holistic integration framework. This approach has been successfully implemented in a list of EU-research projects. This chapter introduces (a) concept models as an instrument for interoperability, (b) a meta model approach as a flexible but stable platform, and (c) hybrid modeling as an approach to flexibly compose the conceptual integration. After discussing this theoretical background, the chapter introduces different realization scenarios of hybrid modeling. Each scenario is supported differently by the underlying meta modeling platform ADOxx®. Here, the experience of a list of EU-research projects is explained and reflected to enterprise interoperability requirements. Sample solutions are introduced, showing different hybrid modeling implementations. Technical overviews of the ADOxx® meta modeling platforms are introduced and references to open development communities are provided to invite readers to realize their own modeling solutions.

Analisa Pergeseran Magnetic Domain Wall Pada Lapisan Tipis Free Layer CoFeB Untuk Sistem Spin-Valve Tunneling Magneto-Resistance (TMR) Sensor

Telah dilakukan analisa pergeseran magnetic domain wall pada lapisan tipis free layer CoFeB untuk sistem spin-valve Tunneling Magneto-Resistance (TMR). Analisa telah dilakukan dengan menggunakan software Object Oriented Micromagnetic Framework (OOMMF) berdasarkan persamaan Landau-Lifshitz Gilbert (LLG). Analisa pergeseran magnetic domain wall pada CoFeB yang mempunyai ukuran luas 120x100 nm2 dengan variasi ketebalan 1 dan 4 nm. Dari simulasi didapatkan hasil analisa pergeseran magnetic domain wall, histeresis loop dan energi dari sistem ferromagnetik (energy exchange dan demagnetisasi). Pada medan eksternal 299,9 Oersted CoFeB dengan ketebalan 1 nm nilai Mx/Ms adalah 0,99 dan pada ketebalan 4 nm nilai Mx/Ms adalah 0.93. Energi demagnetisasi mempunyai pola naik dengan bertambahnya medan luar dan energi exchange menurun dengan bertambahnya medan luar.
