SBMate: A Framework for Evaluating Quality of Annotations in Systems Biology Models

The interests in repurposing and reusing systems biology models have been growing in recent years. Semantic annotations play an important role for this, as they provide crucial information on the meanings and functions of models. However, there are a limited number of tools that evaluate the existence or quality of such annotations. In this paper, we introduce SBMate, a python package that would serve as a framework for evaluating the quality of annotations in systems biology models. Three default metrics are provided: coverage, consistency, and specificity. Coverage checks whether annotations exist in a model. Consistency tests if the annotations are appropriate for the given model element. Finally, specificity represents how detailed the annotations are. We analyzed 1,000 curated models from the BioModels repository using the three metrics and discussed the results. Additional metrics can be easily added to extend the current version of SBMate.

Model Ownership and Intellectual Property Rights for Collaborative Sustainability on Building Information Modeling

The concept of building information modeling (BIM) requires multidisciplinary collaboration and generates the problem of intellectual property protection for the creator of the model element. Therefore, this research aimed to determine the model ownership factors and intellectual property rights (IPRs) for collaborative sustainability on BIM practices in Indonesia. This research used the qualitative approach of primary data, and questionnaires were distributed to parties involved and experienced with BIM-based projects in Indonesia. The research adopted descriptive and inferential statistics to analyze data obtained from respondents. The results showed that the party that produces the model element is the main factor that owns the model and the IPRs. Meanwhile, the employer will have the right to own the model of BIM in the form of a license, with limited use only for operations, maintenance, and marketing, and they do not have the right to reuse the model for the construction of future projects. This research is expected to contribute to the body of knowledge and provide recommendations for policymaking in construction contracts to better manage BIM-based projects.

Continuous calibration of a digital twin: Comparison of particle filter and Bayesian calibration approaches

Assimilation of continuously streamed monitored data is an essential component of a digital twin; the assimilated data are used to ensure the digital twin represents the monitored system as accurately as possible. One way this is achieved is by calibration of simulation models, whether data-derived or physics-based, or a combination of both. Traditional manual calibration is not possible in this context; hence, new methods are required for continuous calibration. In this paper, a particle filter methodology for continuous calibration of the physics-based model element of a digital twin is presented and applied to an example of an underground farm. The methodology is applied to a synthetic problem with known calibration parameter values prior to being used in conjunction with monitored data. The proposed methodology is compared against static and sequential Bayesian calibration approaches and compares favourably in terms of determination of the distribution of parameter values and analysis run times, both essential requirements. The methodology is shown to be potentially useful as a means to ensure continuing model fidelity.

GLOBALISASI DAN PEMETAAN KEKUATAN STRATEGIS PERTAHANAN MARITIM INDONESIA DALAM MENGHADAPI ANCAMAN TRANSNASIONAL: Berdasarkan Analisis Model Element of National Power: (Political, Military, Economic, Social, Infrastructure, and Information/PMESII)

<p>Arus globalisasi saat ini jelas memberikan ruang gerak yang semakin bebas bagi ancaman untuk masuk dan mengganggu keamanan nasional. Indonesia yang merupakan negara kepulauan terbesar tidak boleh menutup mata terhadap ancaman yang sudah didepan mata yang dapat masuk melalui jalur-jalur perairan strategisnya. Peningkatan kapasitas kekuatan pertahanan maritim menjadi kunci bagi pemerintah untuk terus mengawal langkah Indonesia kedepan dalam menghadapi rangkaian perubahan lingkungan strategis, baik dalam skala regional maupun global. Proyeksi pembangunan kekuatan maritim perlu diberikan prioritas utama untuk menjadikan Indonesia sebagai negara poros maritim dunia yang dipandang negara-negara internasional. Pada akhirnya, Indonesia akan memiliki posisi tawar yang strategis dalam pergaulan internasional apabila mampu membangun kekuatan maritimnya.</p><p> </p><p><strong>Kata Kunci:</strong><strong> </strong>pertahanan, globalisasi, ancaman transnasional, <em>element of national power</em></p>
