The use of a design tool materializing the performative design concept is presented. The association of parametric design with lighting intentions leads to a light-based parametric design approach. This approach have been implemented through an inverse natural lighting model which is intended to aid the daylight design (windows, shading devices or others) in the early stages of architectural de...

(Received 00 Month 200x; In final form 00 Month 200x) We study experimentally parametric amplification in the continuous regime using a transverse-degenerate type-II Optical Parametric Oscillator operated below threshold. We demonstrate that this device is able to amplify either in the phase insensitive or phase sensitive way first a single mode beam, then a multimode image. Furthermore the tot...

Linear optical networks are devices that turn classical incident modes by a linear transformation into outgoing ones. In general, the quantum version of such transformations may mix annihilation and creation operators. We derive a simple formula for an effective Hamiltonian generating the scattering operator of a general linear quantum network. Our formula shows how to compute the effective Ham...

background : there are various variables such as the duration and the client consistency' in using a special contraceptive method as well as some individual determinants. which play important roles in optimal using of different contraceptive methods. iud cu- 380a is a safe and an effective method used by 12.5% urban women in east azarbaijan. correlation between continuation rate of using iud cu...

intrauterine device (iud), a conventional method of contraception is rarely associated with uterine perforation and extra uterine dislocation. a 29 years old woman complaining of vaginal bleeding was referred for pelvic mass identified in ultrasound. the mass was confirmed with ct scan. in laparatomy we found an iud in cul-de-sac and pelvic mass was apparently an organized hematoma. transmigrat...

patients and methods the current quasi-experimental study was conducted on 96 eligible females, who were allocated either to the case or the control group and were selected from homes in the border of zahedan city (southeast of iran) during 2010. convenience sampling by door-to-door visits was used for finding eligible cases. a ttm-based self-administrated family planning questionnaire was used...

We show that a common language can be used to unify the description of parametrically coupled circuits—parametric amplifiers, frequency converters, and parametric nonreciprocal devices—with band-pass filter impedance matching networks. This enables one readily adapt network synthesis methods from microwave engineering in design devices having prescribed transfer characteristics, e.g., gain, ban...

This study presents the parametric investigation of a phase change material (PCM) filled plate-fin heat sink, used for thermal management (TM) electronic components. Two-dimensional (2D) unsteady numerical simulations were carried out using finite-volume-method. The which is acting as conductivity enhancer (TCE), employed with PCM to improve transfer enhancement. Two different volume fractions ...

In this paper we discuss the bandwidth enhancement that can be achieved in multi-Joule optical parametric chirped pulse amplification (OPCPA) systems exploiting the tunability of parametric amplification. In particular, we consider a pair of single pass amplifiers based on potassium dideuterium phosphate (DKDP), pumped by the second harmonic of Nd:glass and tuned to amplify adjacent regions of ...
