Learning a foreign language is a long, error-prone process, and much of a learner's time is effectively spent studying vocabulary. Many errors occur because words are only partly known, and this makes their mental...

As part of a national strategic plan recently established by the Ministry of Education in Israel to strengthen science and technology education, an innovative computerscience (CS) curriculum for middle school was developed. One main goal of the new curriculum is to expose students at an early stage of education to the fundamentals of CS and computational thinking, and to encourage students to study CS in the future. We present the curriculum and its initial implementation, focusing on issues of teachers' professional development.
The purpose of this paper is to reduce the Denial of Service (DoS) attacks on peer-to-peer networks by hiding the position of the file and to prove the effectiveness through the fuzzy logic. In general to protect the ...

Return-Oriented Programming (ROP) is a technique which leverages the instruction gadgets in existing libraries/executables to construct Turing complete programs. However, ROP attack is usually composed with gadgets which are ending in ret instruction without the corresponding call instruction. Based on this fact, several defense mechanisms have been proposed to detect the ROP malicious code. To circumvent these defenses, Return-Oriented Programming without returns has been proposed recently, which uses the gadgets ending in jmp instruction but with much diversity. In this paper, we propose an improved ROP techniques to construct the ROP shellcode without returns. Meanwhile we implement a tool to automatically construct the real-world Return-Oriented Programming without returns shell-code, which as demonstrated in our experiment can bypass most of the existing ROP defenses.

The Goal-oriented Requirement Language (GRL). part of the User Requirements Notation (URN) standard, is used to model and analyze stakeholder goals and requirements. jUCMNav is a free Eclipse-based modeling, analysis, and transformation tool for URN that was first released in 2005. This paper reviews the status of this tool (version 4.4, the 20th official release), highlights its main features, and briefly discusses future development plans.
