Passing over Sisters: Denial of Farhadi’s Unsafe Society

analysis of power in the network society

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...

Denial of Service Issues in Voice Over IP Networks

In this paper we investigate denial of service (DoS) vulnerabilities in Voice over IP (VoIP) systems, focusing on the ITU-T H.323 family of protocols. We provide a simple characterisation of DoS attacks that allows us to readily identify DoS issues in H.323 protocols. We also discuss network layer DoS vulnerabilities that affect VoIP systems. A number of improvements and further research direct...

Ectrodactyly in sisters and half sisters.

An extended family is described in which four sisters and half sisters presented with ectrodactyly. Two of the sisters had associated agenesis of the tibiae. The paper describes the malformations and discusses the management and possible genetic inheritance involved. An autosomal recessive gene seems likely to be the mode of inheritance.

Composition of Message Passing Interface Applications over MPICH-G2

Coupling grid applications requires code modification and high S/W engineering effort. We propose the Ensemble methodology in which message passing components are developed separately and applications, whether regular, irregular, SPMD or MPMD, are composed without component modification. Composed applications are pure Message Passing Interface programs running on MPICH-G2. We demonstrate our ap...
