System and method for identification of fingerprintsA method for automated fingerprint identification and special purpose programmed computer for carrying out the method are disclosed. The method and system comprise identifying a scar region in a set of pixels in a fingerprint image by using a second order Gaussian derivative filter parameterized using standard deviation, wherein the scar region has a width greater that the width of a regular ridge or a valley of separation between ridges; wherein a boundary, intensity, and flow direction of each pixel is calculated; each pixel being connected to a next adjacent pixel using flow co-ordinates and flow directions; wherein the Gaussian derivative filter has an output and the output is thresholded to create an output mask with value=1 at the scar regions and value=0 outside the scar regions; and changing the intensity of pixels in the identified scar region with the intensity of the nearest boundary pixel until the intensities of all the pixels in the scar region are changed to the intensity of their flow direction identified boundary pixels.

FDM 3D printed coffee glove embedded with flexible electronicWith the advances in 3D printing technology, Flexible Electronics can now be exploited to form the so-called “Embedded Electronics”. This paper describes experiences learned from a research project which ran during summer 2016 at KAUST, in collaboration with the Electrical and Computer Engineering Department at Effat University, and aimed at creating a heating coffee glove product operating on double alkaline batteries using Kapton© as a flexible substrate for the circuit. The circuit and its batteries are encapsulated in a 3D printed glove, designed using SolidWorks©. The proposed methodology and techniques applied during this work could be further used in implementing other technologies, such as thermoelectric coolers head patches, smart garments, and flexible smartphones. Limitation and recommendation of the present methodology are also discussed.

Arabic - English Syntax in Translation: Equivalence at Word and Sentence LevelsThis book is designed for all English/Arab students whose major is translation. The aim is to introduce students to English translation through their comprehension of the Arabic syntax, therefore, help them to understand how to think and translate into English. No theoretical concepts in translation studies are discussed here, the reason is to give way to practice because it is through practice that students learn best how to translate any text and not just through theories which are in abundance. But when it comes to applying them, they fail to assist students and professionals to learn properly the skill of a good translator, and cannot be implemented fully as tool to produce a cohesive and coherent target text that can be acceptable by the reader and fully informative and contextually correct in its situationality. That is with no translation loss semantically and with the same meaning and effect as the source text though the ST might sound sometimes incomprehensible in the first instance to the translator.

The dynamic relationship among technological innovation, international trade, and energy productionThe primary objective of this study is to analyze the dynamic association among the green energy production (GEP), green technological innovation (GTI), and green international trade (GIT). This study uses fully modified least square (FMOLS) and dynamic least square (DOLS) for data analysis. This study uses the panel data set starts from 2000 to 2020 for eight south Asian countries. This study find a negative relationship between GEP and EFP. However, green technological innovation and green international trade have positive significant association. This study recommends several policy implications regarding the economies of south Asia (SA) based on empirical findings: to subsidize the industries for the installation of renewable projects for the production of renewable energies.

Methodology to Improve Energy Efficiency of Heritage Buildings Using HBIM-Sabil Qaitbay: A Case Study from EgyptOver the last few decades, reducing energy consumption in existing buildings became vital. Although architectural heritage values do not allow typical retrofit interventions, research and practice have demonstrated that heritage buildings can be energy efficient without compromising the building’s heritage values. This article shows the results of energy analysis performed on heritage buildings with HBIM-based simulations such as Revit, Insight, and Green Building Studio. These tools were used to study the energy performance and thermal comfort of Sabil Qaitbay in Cairo, a heritage building built in the fifteenth century, and it is currently used as a library and school for cinema and television. The building history and the conservation values of the current project were studied. Then, the methodology to improve the energy efficiency of heritage buildings using HBIM was discussed. Moreover, two proposals were applied to the current base case, and the potential energy saving for each proposed intervention was investigated. The simulation confirmed a possible reduction of 18.7% in energy consumption with the lowest-cost interventions and 33% with the highest-cost interventions.
