There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

비만아 부모의 돌봄 경험: q 방법론

A solar energy harvesting power supply has been developed for ocular implants. A photovoltaic array embedded under the eye's conjunctiva coverts incident solar energy to electrical energy to be stored in a battery. We have shown that a photovoltaic array embedded under the conjunctiva, with an area of 62mm2, when irradiated at 1mW/mm2 of sunlight, can generate 1.22mW at the battery charging circuit's output. This suggests the feasibility of powering ocular implants by scavenging solar energy from the environment.

In this work, the 3D explicit FDTD method in a D-H formulation similar to (D. Sullivan, 2000) has been used to calculate the electromagnetic fields in the human head due to the operation of the wireless link at 10 MHz of the proposed retinal prosthesis system. The specific absorption rate (SAR) was obtained from the E-field values to compare with safety standards.
