Security Analysis, Enhancement and Implementation of IoT Systems
, M.Sc. Thesis Sharif University of Technology ; Salmasizadeh, Mahmoud (Supervisor) ; Gholampour, Iman (Co-Supervisor)
Abstract
The Internet of Things remains a matter of concern in the minds of the activists in the field after being raised. The structure of an IoT-based system, the components of an IoT-based system, the requirements and limitations of the Internet of Things are the most important parts of which no clear description of them has ever been presented. Structural modifiability, processing constraints, energy supply constraints, and most importantly the security of an IoT-based network are among the issues that have complicated the analysis of an IoT-based System. So providing a clear scheme and an open system for such networks can make it easier to make progress in this area. In this study, we first...
Synthesis and Characterization of Catalytic Micromotors for Biological Applications
, M.Sc. Thesis Sharif University of Technology ; Maddah Hosseini, Hamid Reza (Supervisor)
Abstract
Since 1992, many different methods have been introduced and developed according to the type of application of catalytic Janu micromotors in various fields. In this study, the method of particles masking was used to construct magnesium based catalytic micromotors. The stabilizing of magnesium microparticles was carried out in 3 methods, resuspending with PVP, paraffin and static electricity generation on Slides. Finally, all three methods quality was investigated and paraffin stabilizing was best selected for the stability of particles on the slides. After making the micromotors, the effect of several factors, including the amount of sputtering time, PBS medium with different Ph of (7.4 , 6.4...
