This essay offers a broad view of active defense derived from the concept of active air and missile defense. This view admits a range of cyber defenses, many of which are widely deployed and considered essential in today’s threat environment. Instead of equating active defense to hacking back, this wider interpretation lends itself to distinguishing different types of active defense and the leg...
Boundary-layer wind tunnel provides a unique platform to reproduce urban, suburban and rural atmospheric boundary layer (ABL) by using roughness devices such as vortex generators, floor roughness, barrier walls, and slots in the extended test-section floor in the contraction cone. Each passive device impacts wind properties in a certain way. In this study, influence of various passive devices o...
The most important goals in marring of a country is to destroy it's military and industrial centers. One of the most important and essential measures for preventing the vital damages to these centers or limiting them is to locate accurately these vital and critical industries. Accurate and material location of these centers is one of the most important measures which lead to decrease of future ...
Background: Today, Enemyattack don’t limit to only military weapons. Most of countries move into novel techniques in wars. Bioterrorism is the intentional use of micro-organisms to bring about ill effects or death to humans, livestock, or crops. Increasing of Knowledge about bioterrorism is one of the passive defense applications. Materials and Methods: The aim of this research was to st...
Currently, green rating systems are mainly utilized for correctly sizing mechanical and electrical systems, which have short lifetime expectancies. In these systems, passive solar and bio-climatic architecture, which have long lifetime expectancies, are neglected. Urban rating systems consider buildings and services in addition to neighborhoods and public transportation as integral parts of the...
This paper presents codification of multi-objective passive defense in unit commitment, aiming vulnerability reduction, feeding continuity, reliability enhancement, and increasing confronting potency. Consideration of multi-objective passive defense in the operation and planning of generation units is one of the important principles in dealing with military threats. In this work unit commitment...
How to deploy passive building design strategy adaptive to climate change scenarios at urban neighbourhood level is currently not well understood. A microclimate change outdoor and indoor coupled simulation assessment framework for passive building adaptation design in an urban neighborhood context is proposed. Based on computational modelling, it was developed to investigate summer overheating...
Nudibranchs are marine invertebrates that use various defenses to deter predators. Peltodoris nobilis is a member of the superfamily Doridoidea and uses de novo chemical synthesis for defense. Hermissenda crassicornis Aeolidioidea nematocyst sequestration Past research explains function evolution in nudibranchs; however, it unknown whether these active or passive. The goal this was determine if...
Background & Objects: Health activities are known as one of the most important support areas for crisis management in all crises, especially military crisis, so the use of preventive measures in this type of activities in A time of peace has become vital. Passive defense as another branch of crisis management in the country, with the type of threat of war and competitive attack, which increases...
Abstract Urban parks are important public multifunctional space used for a wide range of activities. The usage levels of parks depend on the spatial characteristics of the spaces, where its forms and occupancies are referred as the usage-spatial relationship. Natural elements spatial complexity and park usability is of interest in this study. A photo - questionnaire was conducted among 296 of p...
