Efficient light extraction from GaN LEDs using gold-coated ZnO nanoparticles
No full textWe experimentally demonstrate the effect of depositing gold-coated ZnO nanoparticles on the surface of GaN multi-quantum well LED structures. We show that this method can significantly increase the amount of extracted light.The support provided by King Fahd University of Petroleum & Minerals (KFUPM) is acknowledged. The authors would like to thank Dr. Mazen Khaled from the Nanotechnology Lab at the chemistry department, KFUPM, Dr. Mohammad Ashraf Gondal from the physics department, KFUPM and the photonics lab at KAUST
Mathematics, Logic, and their Philosophies:Essays in Honour of Mohammad Ardeshir
No full textThis volume is a collection of essays in honour of Professor Mohammad Ardeshir. It examines topics which, in one way or another, are connected to the various aspects of his multidisciplinary research interests. Based on this criterion, the book is divided into three general categories. The first category includes papers on non-classical logics, including intuitionistic logic, constructive logic, basic logic, and substructural logic. The second category is made up of papers discussing issues in the contemporary philosophy of mathematics and logic. The third category contains papers on Avicenna’s logic and philosophy.Mohammad Ardeshir is a full professor of mathematical logic at the Department of Mathematical Sciences, Sharif University of Technology, Tehran, Iran, where he has taught generations of students for around a quarter century. Mohammad Ardeshir is known in the first place for his prominent works in basic logic and constructive mathematics. His areas of interest are however much broader and include topics in intuitionistic philosophy of mathematics and Arabic philosophy of logic and mathematics. In addition to numerous research articles in leading international journals, Ardeshir is the author of a highly praised Persian textbook in mathematical logic. Partly through his writings and translations, the school of mathematical intuitionism was introduced to the Iranian academic community

An Online Numeral Recognition System Using Improved Structural Features – A Unified Method for Handwritten Arabic and Persian Numerals
Get PDFWith the advances in machine learning techniques, handwritten recognition systems also gained importance. Though digit recognition techniques have been established for online handwritten numerals, an optimized technique that is writer independent is still an open area of research. In this paper, we propose an enhanced unified method for the recognition of handwritten Arabic and Persian numerals using improved structural features. A total of 37 structural based features are extracted and Random Forest classifier is used to classify the numerals based on the extracted features. The results of the proposed approach are compared with other classifiers including Support Vector Machine (SVM), Multilayer Perceptron (MLP) and K-Nearest Neighbors (KNN). Four different well-known Arabic and Persian databases are used to validate the proposed method. The obtained average 96.15% accuracy in recognition of handwritten digits shows that the proposed method is more efficient and produces better results as compared to other techniques
Digital Access to LRC services and resources during COVID-19 Pandemic: Prince Mohammad Bin Fahd University LRC Experience
No full textThis paper was given by Mohamed A. Abdulla and Elvira A. Zingapan, Prince Mohammad Bin Fahd University
This study aims to discuss digital access to the Learning Resources Center services and resources during the COVID-19 pandemic.The PMU LRC’s response on the pandemic situation during the periods of closure concerning resources and services is discussed and analyzed. The LRC implements new virtual services and expands the electronic resources to ensure that the PMU community is able to access the resources and information that they needed. The LRC makes efforts to gain access to their digital and physical collections as well as to provide their services remotely, with the transformation of teaching from traditional style to distance learning.There are several virtual initiatives that LRC has taken to promote digital access to the library resources and to make LRC services more efficient while challenging to deliver access to information with library closure. The researchers also examine the changes that PMU library has made to library services throughout the year 2020.</p
