Design of Bluetooth Automatic Check in System Without Operation Based on Cross Mobile Platform

Because the traditional way of sign in is not to call the roll, or sign in on the paper list, or sign in through fingerprint recognition and face recognition, on the one hand, it is cumbersome and time-consuming, on the other hand, it is non-human. The update of roll call sign in is a hot topic at present, and many new schemes rush out. This paper introduces the automatic sign in system based on Bluetooth technology, which does not rely on the mobile phone operating system, does not need the mobile phone installation software, as long as you bring a mobile phone, you can realize automatic sign in. This paper designs and implements the automatic check-in system, and compares it with other ways, proving that it is an innovative check-in method.

Discrete Symmetry Transformations of Third Order Ordinary Differential Equations and Applications

Third order ordinary differential equations have already been classified by the Lie algebra they admit. Invariant equations corresponding to these Lie algebras are also available in the literature [17]. In this paper, list of all discrete symmetries corresponding to these invariant ordinary differential equations, are obtained. Some particular examples are given to show the significance of the work.

RESUME ANALISIS DAN PERANCANGAN APLIKASI SISTEM INFORMASI AUDIT MUTU INTERNAL DAN DOKUMENTASI PENJAMINAN MUTU PERGURUAN TINGGI

Perkembangan teknologi yang sangat pesat memberikan nilai lebih bagi perguruan tinggi untuk meningkatkan keamanan dan kemudahan dalam menyimpan informasi. Teknologi tidak hanya menggunakan data sistem informasi secara umum, tetapi juga membantu dalam proses audit internal. Perguruan tinggi dan pendidikan saat ini memerlukan penjamin mutu guna memastikan mutu pendidikan. Penerapan sistem penjaminan mutu yang sudah berjalan memerlukan proses audit internal guna memastikan proses mutu tetap berjalan. Internal audit memiliki peran penting dalam suatu manajemen, dimana pelaksanaan audit internal dilakukan dengan form-form audit dalam bentuk kertas maupun secara elektronik. Sehingga permasalahan di atas membutuhkan alat bantu dengan sedikit melakukan isian dan secara otomatis sistem akan menyalin semua kode yang sama berbasis paper list, mengolah dalam bentuk file presentasi (grafik), analisis data dan lainnya. Auditor dapat menambahkan atau mengurangi data dengan pengisian langsung pada menu klausa pertanyaan. Selain itu, auditor dapat langsung memberikan catatan temuan serta kapan departemen atau unit kerja dapat memberikan tanggapan terhadap temuan itu untuk diselesaikan dari segi manajemen historikal hasil audit yang akurat dan tersaji secara cepat, serta dapat dibandingkan antara hasil audit setiap departemen, setiap klausul maupun atas waktu. Hasil audit juga menyajikan performance setiap departemen dalam bentuk angka (ukuran kuantitatif). Selain itu, perangkat lunak dapat menyajikan record audit per auditor untuk membantu evaluasi, dan meningkatkan kompetensi auditor.Kata kunci: auditor internal, penjamin mutu, paper list, manajemen historikal, record audit.
