The focus of this paper is to describe and evaluate the security hazards and risks involved with wireless LANs within a business environment, present performance issues that must be addressed and introduce a new protocol, Intelligent Wireless Management (IWM) to enhance network performance. Performance evaluation is based on the results of experiments conducted using the network simulator (ns).

Climate change is a major challenge for Indonesia due to its impact on food, water, energy sustainability, and environmental health. Almost all Indonesian regions are exposed floods, landslides, soil erosion, drought, heavy rains. In response these challenges, the Government of has determined integrated watershed management (IWM) be one key programs reduce greenhouse gas (GHG) emissions, as sta...

Initiatives to reduce the reliance of agriculture on pesticides, including European Union (EU) Directive 2009/128/EC sustainable use pesticides (SUD), have yet lead widespread implementation Integrated Pest Management (IPM) principles. Developments in weed management strongly focused increasing efficiency herbicides or substituting with other single tactics such as mechanical control. To increa...

این پژوهش با الهام گرفتن از نتایج یک طرح مطالعاتی کاربردی، رویکرد سلسله­‌مراتبی جهت پیگیری فرایند توسعه تأمین‌کنندگان و حمایت تصمیمات موجود در هر مراحل آن ارائه‌ می‌کند. ابتدا، زمینه‌های تأمین نیازمند سپس واجد شرایط هریک زمینه‌ها به کمک تصمیم‌گیری چندشاخصه بهترین-بدترین مشخص می‌گردند. معیارهای شناسایی نیز مرور مطالعات پیشین بهره‌گیری نظرات خبرگان حوزه‌ی خرید استخراج‌شده‌اند. درنهایت، مدل ریاضی ...

Focused wideband adaptive array processing algorithms are used for the high-resolution aeroacoustic directionfinding of ground vehicles. Methods based on coherent focusing such as steered covariance matrix (STCM), and spatial smoothing or interpolation using the array manifold interpolation (AMI) method, will be discussed [1, 2]. Experimental results for a circular array are presented comparing...
