Secrecy Outage Probability and Fairness of Packet Transmission Time in a NOMA System [PDF]
IEEE Access, 2020 في هذه الورقة، نقوم بتحليل احتمالية انقطاع السرية (SOP) ونزاهة متوسط وقت نقل الحزمة لنظام الوصول المتعدد غير المتعامد (NOMA) الذي يتكون من محطة قاعدة (BS) واثنين من مستخدمي NOMA القانونيين في وجود جهاز تنصت (EVE). من أجل استخراج الإشارة المتراكبة، يتم اعتبار EVE في وضعين، أي وضع إلغاء التداخل المتتالي (SIC) ووضع إلغاء التداخل المتوازي (PIC). وفقًا لذلك،

On the Analysis of Secrecy Outage Probability Using Average Channel Capacity
Sakarya University Journal of Science, 2020 In this article, we analyze the outage probability of physically secure wireless signal transmission in fading envi-ronments where both primary and eavesdropper channels are subject to generalized fading. We propose a novel approach using the average channel capacity of the primary channel and that of the eavesdropper channel to the outage probability ...

Stabilising Routines in Complex Emergencies: How Basic Service Continuity Shapes Perceived Security
Public Administration and Development, EarlyView.ABSTRACT This study examines how locally embedded actors describe the relationship between basic service continuity and perceived security in complex emergencies, with particular attention to the stabilisation of everyday routines. Using Proximity‐Predictability‐Attributability (PPA) as an analytic lens, we trace how interviewees relate access to water,

A Semi‐Quantitative Methodology for Chemical Process Resilience Assessment
Safety Science and Technology, EarlyView.A new semi‐quantitative framework is proposed for process resilience assessment. Safety/security, productivity, and quality are integrated into the resilience evaluation. Dynamic simulations are used to quantify resilience as a time‐dependent system response.
