Photosynthetic bacteria contain bacteriochlorophyll (BChl) that absorbs light and delivers the resulting singlet excitation energy to photochemical reaction centers.' The reaction centers, which have been isolated in a form free of lightharvesting BChl,'-3 contain a photochemically specialized BChl which in Rhodopseudomonas spheroides is called P870 after its absorption maximum near 870 nm. Exc...

Photosynthetic rates of six pistachio cultivars were studied including Ohadi, Kalleh-Ghochi, Akbari, AhmadAghaii, Rezaii Zoudras and Haratii. Measurements were done using OFF and ON shoots at different stages of fruit growth and development included: - Beginning of endocarp growth; - pith hardening; - Beginning of endosperm rapid growth; - end of embryo development; - ripening and harvesting ti...

Oscillating foils in synchronized pitch and heave motion can harvest hydrokinetic energy while leaving behind a distinct trail of alternating signed vortices. This work correlates the specific foil kinematics (frequency, pitch, amplitude) with resulting wake structure by defining three modes within harvesting kinematic regime. Using an array two tandem oscillating foils, performance trailing is...

We study wireless power transmission by an energy source to multiple harvesting nodes with the aim maximize efficiency. The transmits using one of available levels in each time slot and transmit information back harvested energy. does not have any channel state it only knows whether a received codeword from given node was successfully decoded or not. With this limited information, has learn opt...

Automation in cherry harvesting is essential to reduce the demand for seasonal labor for cherry picking and reduce the cost of production. The mechanical shaking of tree branches is one of the widely studied and used techniques for harvesting small tree fruit crops like cherries. To automate the branch shaking operation, different methods of detecting branches and cherries in full foliage canop...
