Bob Abel, pp. 67Dr. El-Sayed was born in Alexandria, Egypt. After secondary school, he went to the University of Alexandria for his B.S. (1949) in Oceanography. After his M.S., he went to the Scripps Institute of Oceanography on a Fulbright Fellowship. He received his PhD from the University of Washington. As professor emeritus at Texas A & M, he directs a project with the Cooperative Marine Research Program in the Middle East. A friend asked him to work on a biological project on Drake Passage, Antarctica.
He worked for several years on vessels from Argentina and was later assigned to a ship for the study of krill. The science team included specialists interested in different aspects of the ecosystem. This was the first of many trips, including those on the Atlantic Ocean, Pacific Ocean, and Indian Ocean. He wrote the book “The Historical Perspective of the Antarctic Marine Research.” This book addresses the studies on the productivity of krill, in addition to phytoplankton and how solar radiation, nutrients, and the depletion of the ozone affected the marine ecosystem. The UVB radiation had a deleterious effect on the survival of the phytoplankton and nanoplankton.
Dr. El-Sayed describes his associations with SCAR, BIMASS, SCORE, and other research organizations. He summarizes the phasing out of CFCs production. Because some phytoplankton are inhibited by solar radiation, the maximum concentration of chlorophyll is between 10 and 20 meters. As a member of the Nimbus Experimental Team, Dr. El-Sayed used the coastal zone color scanner to study the krill ecosystem.

Minimizing cogging torque in permanent magnet synchronous generators for small wind turbine applications
No full textPermanent magnet synchronous generators have a wide usage among electric machines, especially in small wind turbine systems. However permanent magnet synchronous generators suffer from cogging torque due to the magnetic interaction between the poles of the rotor’s permanent magnets and the steel laminations of the stator’s teeth. The cogging torque drawback is a major problem in this kind of generators that affects its functionality negatively. In the literature many different approaches for reducing the cogging torque are proposed and each different approach achieves different amount of reduction in the cogging torque. In this study 6 different cogging torque reduction techniques are considered and with finite element simulations using the JMAG simulation software, they are compared with each other in terms of percent reduction in the cogging torque. Present simulations show that among the considered different approaches, continuous skewing technique reduces the cogging torque the most with respect to the each other techniques considered. Also using the step skewing of the rotor or stator, changing the slot opening width and having dummy slots techniques can decrease the cogging torque more or less the same amount in magnitude. Present results indicate that changing the radial shoe depth technique has almost no effect in reducing the cogging torque
