The two-dimensional electron gas charge-coupled device (ZDEG-CCD) structure for 111-V and other heterojunction materials is reviewed. Device design considerations for gate, insulator, and channel material parameters are presented. Optimization of ZDEG-CCD performance parameters such as well capacity, dark current, and transfer efficiency is discussed. Experimental results on AIGaAs/GaAs uniform...

Olive products, such as oils, olives and leaves infusions, have been used in the past to treat many health problems. This study aims to develop a methodology for maximizing the efficiency of extraction of polyphenols from olive leaves. For this purpose, two experimental design approaches (a central composite design (CCD) and a mixture design) have been used. The optimal extraction parameters ob...

This paper reports on two new advancements in CCD technology. The first area of development has produced a special purpose CCD designed for ultra low-signal level imaging and spectroscopy applications that require subelectron read noise floors. A nondestructive output circuit operating near its 1/f noise regime is clocked in a special manner to read a single pixel multiple times. Off-chip elect...

During the maintenance period of a future fusion reactor power plant, called DEMOnstration Power Plant (DEMO), remotely handled casks are required to confine and handle DEMO in-vessel components during their transportation between active facility. In order limit dispersion activated dust, Contamination Control Door (CCD) is designed be placed at an interface separable containments (e.g., vacuum...

Astronomical CCD systems based on second-generation DINACON controllers were developed at the SAO RAS Advanced Design Laboratory more than seven years ago and since then have been in constant operation at the 6-meter and Zeiss-1000 telescopes. Such systems use monolithic large-area CCDs. We describe the software developed for the control of a family of large-area CCD systems equipped with a DIN...

In the present study, a comparison of central composite design (CCD) and Taguchi method was established for Fenton oxidation. [Dye]ini, Dye:Fe(+2), H2O2:Fe(+2), and pH were identified control variables while COD and decolorization efficiency were selected responses. L 9 orthogonal array and face-centered CCD were used for the experimental design. Maximum 99% decolorization and 80% COD removal e...

The measurement and prediction of dye concentration is important in the design, planning and management of wastewater treatment. Soft computing techniques can be used as a support tool for analyzing data and making prediction. In this study, Central Composite Design (CCD) and adaptive neuro-fuzzy inference system (ANFIS) are employed to identify and predict the output intensity ratio of light t...

In this article a comparative study for modeling and optimization of 2-methylpropane-2-thiol removal from contaminated soil by ultrasound is investigated. Central Composite Design (CCD) and artificial neural network (ANN) were utilized and compared to each other in order to obtain appropriate predicting model with respect to sonication power (w), sonication time (min) and water/reactor volume r...
