Macs: An Accelerator-Based Radioisotope Measuring System

An Automatic Real Time Impedance Matching System for Use in an RF Electrostatics Accelerator Ion Source

Measuring the Skyshine from Linear accelerator in Rajaee Oncology Hospital

Introduction: Radiation therapy is using the ionizing radiation to eliminate or minimize cancerous tissues. This method has been very much considered in recent years. Because of the high energy of the photons produced by the accelerator, it is necessary to protect the walls, roof and the floor of the treatment rooms using the concrete and leaden materials. One of these harmful ...

New Generic Attacks against Hash-Based MACs

In this paper we study the security of hash-based MAC algorithms (such as HMAC and NMAC) above the birthday bound. Up to the birthday bound, HMAC and NMAC are proven to be secure under reasonable assumptions on the hash function. On the other hand, if an n-bit MAC is built from a hash function with a l-bit state (l ≥ n), there is a well-known existential forgery attack with complexity 2. Howeve...

Clinical Experience of an Iontophoresis Based Glucose Measuring System

Currently finger pricking is the common method of blood glucose measurement in patients with diabetes mellitus. However, diabetes patients have proven to be reluctant to check their glucose profiles regularly because of the discomfort associated with this technique. Recently, a non-invasive and continuous Reverse Iontophoresis based Glucose Monitoring Device (RIGMD) was developed in Korea. The ...

Use of a Virtual Accelerator for a Development of an Accelerator Control System

Concept of Virtual accelerator is introduced to develop beam control application programs in the KEKB accelerator control system. A virtual accelerator is a computer process which simulates behavior of a beam in an accelerator and responds to the accelerator control program under development in a same way as an actual accelerator do. Users of the virtual accelerator can test their control algor...
