—A novel process for monolithic integration of RF MEMS switches with three-dimensional (3-D) antenna elements on a microwave laminate printed circuit board (PCB) is presented. This process calls for a low temperature (90-170 o C) high-density inductively coupled plasma chemical vapor deposition (HDICP CVD) technique that allows the choice of any PCB… (More)
Both angular and linear measurements have been proposed in the assessment of sagittal jaw relationship. Many distorting factors may influence the validity of evaluating this relationship. This article was undertaken to study the different measurements statistically and geometrically; in addition, the AF-BF distance as the absolute measurement of the… (More)
A simple method for magnification correction of width measurements from posteroanterior (PA) cephalograms is presented. Small lead markers were placed on selected landmarks of dry skulls. Lateral and PA cephalograms were obtained for each skull. Seven cephalometric width measurements were selected. Actual widths were deduced from the geometric principle of… (More)
 Water scarcity may appear to be a simple concept, but it can be difficult to apply to complex natural-human systems. While aggregate scarcity indices are straightforward to compute, they do not adequately represent the spatial and temporal variations in water scarcity that arise from complex systems interactions. The uncertain effects of future climate… (More)
Keywords: Aluminum doped zinc oxide (AZO) Hydrogen plasma Magnetron sputtering Resistivity Aluminum doped zinc oxide (AZO) thin films prepared by radio-frequency (RF) magnetron sputtering at various RF power were treated by hydrogen plasma to enhance the characteristics for transparent electrode applications. The hydrogen plasma treatment was carried out at… (More)
In order to explore the growth changes in facial configuration, 160 subjects (80 young adults and 80 children aged 11-12) with normal occlusion were selected for roentgenocephalometric analysis. The present study led to the following conclusions: (a) The ratios of anterior upper to anterior total facial heights, anterior lower to anterior total facial… (More)
Emittance coupling between vertical and horizontal planes at TLS has been investigated. Using a set of skew quadrupoles, the coupling can be corrected to an acceptable value. The coupling sources are studied and possible errors are reduced.
Preface In any form of electronic communication, errors can occur and hence there is a need to deal with them. Before error-correcting codes were used, only once a message had been received and could not be understood, one could conclude that errors had occurred. There was no way to resolve these errors other than asking for retransmission. This changed… (More)
Consulting/Patents Pending B.A. Cetiner and H. Jafarkhani, " Adaptive multiple-input multiple-output (MIMO) wireless communications systems, "
The purpose of this study was to provide more information about the morphological characteristics of the craniofacial complex in mandibular prognathism. Forty young adult males having mandibular prognathism were compared with 40 having normal occlusion. This was conducted to carry out geometric morphometric assessments to localize alterations, using… (More)
