HYDRAULIC TECHNOLOGY AND UTILIZATION OF OCEAN WAVE POWER

Tuning of fuzzy logic controller using an improved black hole algorithm for maximizing power capture of ocean wave energy converters

Seas and oceans are the most important sources of renewable energy in the world. The main purpose of this paper is to use an appropriate control strategy to improve the performance of point absorbers. In this scheme, considering the high uncertainty in the parameters of the power take-off system in different atmospheric conditions, a new improved black hole algorithm is introduced to tune fuzzy...

Analytical Investigation of the Effects of a Standing Ocean Wave in a Wave-Power Device OWC

In this work we study analytically and numerically the performance of the mean heave motion of an OWC coupled with the governing equation of the spreading ocean waves due to the wide variation in an open parabolic channel with constant depth. This paper considers that the ocean wave propagation is under the assumption of a shallow flow condition. In order to verify the effect of the waves in th...

Blast Shock Wave Mitigation Using the Hydraulic Energy Redirection and Release Technology

A hydraulic energy redirection and release technology has been developed for mitigating the effects of blast shock waves on protected objects. The technology employs a liquid-filled plastic tubing as a blast overpressure transformer to transfer kinetic energy of blast shock waves into hydraulic energy in the plastic tubings. The hydraulic energy is redirected through the plastic tubings to the ...

the effect of the utilization of electronic dictionaries on depth and breadth of vocabulary knowledge: a case of iranian efl learners

مطالعه حاضر تلاشی است برای بررسی تأثیرات به کارگیری فرهنگ لغات ، یکی از مهمترین ابزارهای یادگیری واژگان درفراگیری زبان خارجی، بر روی دانش لغوی. دراین تحقیق فرهنگ های الکترونیکی در قیاس با فرهنگ های چاپی مورد بررسی قرارگرفته اند که آیا این فرهنگ ها تاثیرقابل توجهی بر روی دوبعد کمی و کیفی دانش لغوی یعنی عمق و گستره لغات می گذارند. همچنین مشخص گردیده است که آیا تفاوت قابل ملاحظه ای میان عمق و گستر...
