1/60th or 1/80th. (Callaghan, et al., 2012) For example, a person’s salary at retirement was £24,000 and he has worked for 40 years until retiring. In a 1/60th scheme, he would receive a pension of: 1/60×£24,000×40=£16,000 a year. Normally, if members of DB occupational pension schemes want to draw the pension, they need wait until the age of 60 or 65. Otherwise, there would entail a reduction of around 5% per year of early retirement. For instance, if the normal retirement age is 60, the retirement at

the process of stimulating the brain using methods such as electricity, magnetic waves, and more. Deep Brain Stimulation (DBS) is the stimulation of regions deep within our brain. The current way we can do this is by implanting electrodes on to the sub-thalamic nucleus (STN) through surgery. Throughout this project, I decided that my focus should be on the possibility of DBS being implementing noninvasively. The main reason I want to focus on this is because I want to help people who have mental

The higher frequency that carries the modulation(Intelligience) 3. Describe the two reasons that modulation is used for communications transmissions. To transfer information, such as voices, images, or data. Also, the frequencies employed by the modulated signal are high enough to permit the use of antennas of reasonable length. 4.

appropriate engineering of the waveguide dimensions, conversion bandwidths greater than 150 nm are achieved and peak conversion efficiencies of -9.6 dB are demonstrated. Furthermore, utilizing fourth-order dispersion, wavelength conversion across four telecommunication bands from 1477 nm (S-band) to 1672 nm (U-band) is demonstrated with an efficiency of -12 dB. © 2007 Optical Society of America OCIS codes: (190.4380) Four-wave mixing; (130.5990) Semiconductors; (130.4310) Nonlinear; (130.3060) Infrared

Introduction: A network which freely passes desired band of frequencies while almost suppress other band of frequencies is called filter. This type of network was first examined by G.A Campbell and O.J Zobel of bell telephone laboratories. Filters are networks that process signals in a frequency-dependent manner. The basic concept of a filter can be explained by examining the frequency dependent nature of the impedance of capacitors and inductors. In filters, attenuation changes suddenly as the
