Technology Embedded Imagination for Arab Women

With advancing channels of communication easing the availability of technological tools, the young minds of women in the Arabian Peninsula are ready to adopt forthcoming challenges. The embrace of storytelling in the digital realm by these young minds reflects the interplay of traditional culture, western modernism, and changes brought about by media industries. These women have adopted and used new media as a vehicle to maneuver their interesting and fresh ideas and have seen the rectilinear screen of a computer as an exit through which to come out and say something to the masses. The thinking methodology has culminated in pragmatic and dynamic visuals in order to celebrate, inform, and create awareness about the issues that they see in the region and among the people. With this freedom of expression, they are creating a new visual culture and transforming themselves into a meaningful workforce. With emerging technological tools, they blend intuitive, pragmatic, emotional, and contextual imagination with a highly-sophisticated production pipeline in order to incorporate the challenges of synthesizing ＂dialect＂ and ＂codes＂ that have traditionally been segregated in the culture. Their work is an amalgamation of arts/design, animation, life footage, and meaningful communication. With cyclical evaluation, they entwine the two elements, creativity, and technicality with massive exposure of Digital Assists Management （DAM）. This paper explains how current technological tools and contextualized teaching instructions foster meaningful content with the elicitation and mergence of Arab anthropological characteristics.

Horizontal crustal movement in China fitted by adaptive collocation with embedded Euler vector

The crustal movements of the Chinese mainland include an average regional movement trend of the mainland and complex local deformations. Thus, both trends in the crustal movement of the mainland and local distortions should be simultaneously taken into consideration in crustal movement estimations. A combined collocation model based on Euler vector (taken as trend parameters) and local distortions (taken as signals) is proposed in this paper. We assume that prior covariance matrices between signals and observations should be consistent with their uncertainties. Otherwise, the station movement estimates provided by the collocation will be distorted. Thus, an adaptive collocation estimator based on simplified Helmert variance components is applied. This means that the contributions of signals and observations to estimates of crustal movements are balanced and reasonable, and consistent covariance matrices of the signals and observations are achieved through the adjustment of the adaptive factor. The calculation of actual horizontal movements of the Chinese crust shows that the estimates of horizontal crustal movement velocities are made more accurate by the adaptive collocation model.

Threshold control in VCSELs by proton implanted depth

The proton implantation is one of key procedures to confine the current diffusion in vertical cavity surface emitting lasers(VCSELs),in which the proton implanted depth and profile are main parameters.Threshold characteristics of VCSELs with various proton implanted depths are studied after optical,electrical and thermal fields have been simulated self-consistently in three dimensions.It is found that for VCSELs with confinement radius of 2 mm,increasing proton implanted depth can reduce the injected current threshold power and enhance the laser temperature in active region.Numerical results also indicate that there are optimal values for current aperture in proton implanted VCSELs.The minimum injected current threshold can be achieved in VCSELs with proton implantation near the active region and confinement radius of 1.5 mm,while the VCSELs with proton implantation in the middle of p-type distributed Bragg reflectors(DBRs) and confinement radius of 2.5 mm can realize the minimum temperature.
