چکیده

This paper describes our experience with the BOSS competition in chronological order. The intention is to reveal all details of our effort focused on breaking HUGO – one of the most advanced steganographic systems ever published. We believe that researchers working in steganalysis of digital media and related fields will find it interesting, inspiring, and perhaps even entertaining to read about the details of our journey, including the dead ends, false hopes, surprises, obstacles, and lessons learned. This information is usually not found in technical papers that only show the final polished approach. This work accompanies our other paper in this volume [9].

Weighted-HR: An Improved Hierarchical Grid Resource Discovery

Grid computing environments include heterogeneous resources shared by a large number of computers to handle the data and process intensive applications. In these environments, the required resources must be accessible for Grid applications on demand, which makes the resource discovery as a critical service. In recent years, various techniques are proposed to index and discover the Grid resource...

Weakly-compressible SPH and Experimental modeling of periodic wave breaking on a plane slope

Breaking waves have ability to transport large quantities of sediment and significant impact on coastal structures morphology. Hence, modeling of wave breaking is an important subject in coastal and marine engineering. In this research, the periodic wave breaking process on a plane slope is studied experimentally and numerically. Laboratory experiments were conducted to record water surface ele...

شبیه‌سازی عددی شکست موج تنها بر روی ساحل شیب‌دار به‌ روش هیدرودینامیک ذرات هموار نسبتاً تراکم‌پذیر

In this article, a numerical meshless method called Weakly Compressible Smoothed Particle Hydrodynamic (WCSPH) is used to simulate the solitary wave breaking process on the beach. The present model is a two dimensional model that considers the fluid weakly compressibility. This model solves the viscous fluid equations to obtain velocity field and density and solves the equation of state to obta...

Investigating the Effect of Pressure on the Hugo Point on the Severity of a Headache after Head Injury

Background: A headache is the most common post-traumatic complaint in patients. Nurses can help to relieve the pain and to improve the quality of the care through non-pharmacological methods. The aim of this study was to determine the effect of pressure on Hugo point on the severity of a headache after head injury. Methods: In this clinical trial, 60 patients were randomly divided into two int...

A Spatial-based KDD Process to Better Understand the Spatiotemporal Phenomena

In this paper, we present a knowledge discovery process applied to hydrological data. To achieve this objective, we combine successive methods to extract knowledge on data collected at stations located along several rivers. Firstly, data is pre processed in order to obtain different spatial proximities. Later, we apply two algorithms to extract spatiotemporal patterns and compare them. Such ele...
