The mining boundary ultra-layer & cross-border of some small coal mines in the profit-driven results in a many of safety accidents, waste of resources and environmental damage while the state can not achieve the full uninterrupted supervision because of the backward monitoring tools and equipment. In this situation the real-time monitoring system for underground mining activities is designed based on explosion source location technology. Small and medium-sized coal mines tunnel by blasting operations. The P waves are picked up by acceleration vibration sensors buried underground that are identified and dealt by using wavelet transform. The bursting point is located by the Geiger algorithm and displayed in the mine’s electronic map. The monitor system has good stability, small positioning error by field-proven.

Science does not exists to enlighten people's minds only. It mainly exists to show the educated way from quanta to qualia. And that way starts from computational competence. In previous papers published elsewhere, we have already shown that traditional Q Arithmetic can be regarded as a highly sophisticated open logic, powerful and flexible bidirectional formal language of languages, according to "Computational Information Conservation Theory" (CICT) new perspective. This new awareness can offer competitive approach to guide more effective and convenient algorithm development and application to arbitrary multiscale (AMS) biomedical system modeling and simulation. An articulated example on function computational modelling is presented and compared to standard, well-known and traditional approach. Results are critically discussed.

Dosen dalam aktivitas keseharian memiliki tiga kewajiban yang dikenal dengan “Tridharma perguruan tinggi”. Kurangnya monitoring kinerja dosen dalam beberapa kegiatan yang wajib menyebabkan pimpinan universitas sulit mendapatkan laporan yang rutin dari dosen, sistem ini dibangun berbasis web dengan metode waterfall. Fungsi yang terdapat dalam sistem mencakup input kinerja dosen dalam bidang tri darma perguruan tinggi, yang akan menghasilkan laporan kinerja beserta jam kerja dosen setiap minggu nya. Beberapa pihak seperti atasan Dosen, Asesor, dan pihak kepegawaian di Universitas perlu melakukan monitoring terhadap perkembangan aktivitas setiap dosennya pada tiap semester. Penelitian ini dimulai dari penelusuran referensi pedoman angka kredit dari kementerian pendidikan dan kebudayaan, setelah itu kami melakukan wawancara dengan pihak dari kepegawaian untuk perancangan sistem monitoring yang akan dibuat. sistem yang dibuat menggunakan kerangka kerja waterfall dan pemodelan sistem menggunakan unified modelling language (UML). Sebelum sistem diimplementasikan, pengujian diawali dengan membagikan panduan pengguanaan terlebih dahulu dan memberikan kesempatan kepada entitas yang terlibat untuk mempelajarinya. Pengujian lebih ditekankan pada aspek penguasaan terhadap penggunaan sistem ini. Hasil dari penelitian ini yaitu sistem yang dapat merekam kinerja seluruh dosen secara digital, dan informasi kinerja dosen dapat diakses oleh pihak universitas untuk dijadikan bahan untuk penilaian kinerja dimasa mendatang.   Kata kunci: kinerja, monitoring, sistem, Tridharma perguruan tinggi, dosen.   Abstract Lecturers in their daily activities have three obligations, known as “three pillars of higher education.” Insufficient monitoring of lecturers' performance in their mandatory activities may cause difficulty for university leaders to obtain regular reports from lecturers. We built a system on a web-based basis with the waterfall method, contained an input page for the performance of lecturers in their mandatory activity, which will generate performance reports, including the working hours every week. Some Persons are required to monitor the activities of each lecturer in every semester. We started to trace the reference for the credit score guideline from the ministry of education and culture, then we conduct interviews with Human Resources Department for monitoring system design. The systems created using the waterfall framework and system modeling using the unified modeling language (UML). Before implementation, we were conducting testing by sharing the user guide and giving the involved entities the opportunity to learn it. Testing is more emphasized on aspects of mastery of the use of the system. The outcome of this work is a system that can record the performance of all lecturers digitally, and lecturer performance information can be accessed by the university as a materiall for further assessments. Keywords: performance, monitoring, system, three pillars of higher education, lecturer.

Unmanned Underwater Vehicle (UUV) formation system has an important role in the utilization of marine resource. In order to provide an efficient method to research modeling and simulation of UUV formation in the marine environment, the novel approach based on Multi-Agent Interaction Chain was proposed for the UUV formation system. Firstly, Multi-Agent Interaction Chain was analyzed, which mainly considered task and role of UUV in the formation, and the overall modeling process of UUV formation system based on Multi-Agent Interaction Chain was established. Then, the static structure of Multi-Agent Interaction Chain was researched focusing on Hybrid UUV-Agent model structure from the UUV-Agent State-Set and UUV-Agent Rule-Base which were the two aspects to strengthen reliability of interaction chain; the dynamic mechanism of Multi-Agent Interaction Chain was designed, which was focused on collaboration model and communication model through the Adaptive Dynamic Contract Net Protocol and KQML/XML/RTI. Finally, three experiments were established to verify the validity and effectiveness of proposed modeling approach for UUV formation system. Simulation results show the proposed model has good performance, which has important theoretical innovation and application prospects.
