Characteristics of an Insect-mimicking Flapping System Actuated by a Unimorph Piezoceramic Actuator
Nguyen, Viet-Quoc,Syaifuddin, M.,Park, H.C.,Byun, D.Y.,Goo, N.S.,Yoon, K.J. SAGE Publications 2008 Journal of intelligent material systems and struct Vol.19 No.10
<P>This study introduces an insect-mimicking flapping-wing system, where the rotation, corrugation, and clapping of insect wings have been mimicked. Unlike most motor-driven flapping systems, the flapping in this system is actuated by a unimorph piezoceramic actuator. The artificial wings are first made of a thin polyethylene sheet and then corrugated. As the wings are assembled through a pitching hinge, they can passively rotate about the hinge during the flapping motion due to the resultant aerodynamic force. The effects of the rotation, corrugation, and clapping of the wings are experimentally explored with respect to the vertical force produced by the flapping system. A smoke-wire flow visualization is also conducted to confirm whether the flapping-wing system can generate leading edge and trailing edge vortices, which are essential for generating lift and thrust in insect flight.</P>

Economics During Global Recession: Sharia-Economics as a Post COVID-19 Agenda
Aryati ARFAH,Fahruddin Zain OLILINGO,S. SYAIFUDDIN,D. DAHLIAH,N. NURMIATI,Aditya Halim Perdana Kusuma PUTRA 한국유통과학회 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.11
This research is a literacy study regarding the implementation and management of the economic role of haria as a new strategy in overcoming the problem of the global financial crisis that has hit the middle of the COVID-19 pandemic. The research method comes from previous studies to compare the capitalist, socialist, and sharia economic systems. In response to various economic uncertainties, both internal and external, the ability to seize opportunities and transform has become the key to economic resilience. Islamic economics can be an alternative in responding to the dynamics of the global and national economy. Several things need to be taken into consideration in fulfilling the sharia economy and the primary strategy chosen must come from the inputs given by the stakeholders, including business actors, associations, regulators as well as experts, and academicians. The primary strategy in implementing the sharia economy also requires the support of various parties in order to develop sustainability. Strengthening regulation and governance is one of the fundamental factors. Optimization of the sharia economy based social sector such as Zakat, Infaq, Sadaqah, and Waqaf can be optimized both for collection and distribution so that the concept of sharing can certainly support the development and the economy both nationally and globally.
