Abstract

Bone fractures refer to the phenomenon of bone breakage or detachment caused by intensive loads. The primary causes of bone damage include incidents, traffic accidents, and sports injuries. One of the materials commonly used for bone support applications is 316L stainless steel. The design process for T-type bone supports involves creating mechanical drawings and simulations to demonstrate the material's behavior when subjected to mechanical and thermal loads during use by patients.In this study, the researchers aim to examine the mechanical and thermal properties of T-type bone plates using the Finite Element Analysis (FEA) method. The technical drawing of the T-type bone support is developed in Autodesk Fusion 360. The simulations involve the application of static and thermal loads. The loads applied to the T-type bone plate include compressive forces of 1 N, 10 N, 50 N, 85 N and 500 N, as well as temperatures of 28°C, 500°C, 800°C, 950°C, and 1400°C. The smallest stress is observed at a force of 1 N, resulting in a stress of 4.64 MPa, while the highest stress is recorded at a force of 500 N, producing a stress of 2319.70 MPa. Forces below 50 N are considered the safest to avoid deformation during loading. Additionally, temperatures below 912°C are optimal for the operation of bone supports.

Abstract

Dalam penelitian mengidentifikasi pengaruh ukuran buffer dalam proses duplikasi file dengan ukuran file 1 gigabyte (GB) dan menggunakan sistem file tmpfs. Baseline code menggunakan operasi tingkat-rendah (low-level operation) seperti open(), creat(), read(), dan write(). Penelitian ini bertujuan untuk mengoptimasi proses duplikasi file menggunakan tiga metode. Pada tahap awal, penulis mengidenfikasi beberapa isu yang terdapat pada operasi read/write pada sistem file linux. Terdapat tiga metode yang akan diinvestgasi dalam penelitian ini, pertama, meningkatkan ukuran buffer, kedua membandingkan fungsi  creat() dan open(), ketiga menganalisa fungsi O_Direct() pada tmpfs. Untuk duplikasi file, ukuran buffer menjadi hambatan kinerja pada proses sistem file ini. Karena jumlah read() tergantung pada ukuran buffer, sehingga operasi baca-tulis terus beralih antara mode pengguna dan mode kernel.
