The Camellia block cipher has a 128-bit block length and a user key of 128, 192 or 256 bits long, which employs a total of 18 rounds for a 128-bit key and 24 rounds for a 192 or 256-bit key. It is a Japanese CRYPTREC-recommended e-government cipher, a European NESSIE selected cipher, and an ISO international standard. In this paper, we describe a few 5 and 6-round properties of Camellia and fin...

This paper studies the application of the hypercube queueingmodel to SAMU-192, the urban EmergencyMedical Service of Campinas in Brazil. The hypercube is a powerful descriptive model to represent server-to-customer systems, allowing the evaluation of a wide variety of performance measures for different configurations of the system. In its original configuration, SAMU-192 had all ambulances cent...

The aim of this study was to focus on certain characteristic problems associated with Iridium-192 high dose-rate brachytherapy (Ir-192 HDR-BT) in combination with external beam radiation therapy (EBRT) in the treatment of patients with localised prostate cancer. Over a period of 16 years, >2,000 patients with prostate cancer have been treated in Sweden with a combination of two fractions of 10 ...

The SPEEDY block cipher family announced at the CHES 2021 shows excellent performance on hardware architectures. Due to nature of hardware-friendly design SPEEDY, algorithm has low for software implementations. In particular, 6-bit S-box and bit permutation operations are inefficient in implementations, where it performs word-wise computations. We implemented a 32-bit microcontroller first time...
