Detecting occluded faces is a non-trivial problem for face detection in computer vision. This challenge becomes more difficult when the occlusion covers majority of the face. Despite the high performance of current state-of-the-art face detection algorithms, the detection of occluded and covered faces is an unsolved problem and is still worthy of study. In this paper, a deep-learning-face-detection model Niqab-Face-Detector is proposed along with context-based labeling technique for detecting unconstrained veiled faces such as faces covered with niqab. An experimental test was conducted to evaluate the performances of the proposed model using the Niqab-Face dataset. The experiment showed encouraging results and improved accuracy compared with state-of-the-art face detection algorithms

Healthcare service institutions (HSIs) have sought ways to motivate patient loyalty in response to surging rates of medical tourism. Previous research indicates that Hospital Information System (HIS) is essential for HSIs to gather, measure, and analyze the massive amounts of data required to generate patient loyalty. There is currently no consensus on the factors that comprise HIS specifically geared towards motivating patient loyalty (HISPL). Furthermore, HIS requires full adoption by HSI staff to be effective. Thus, to reduce wastage of HSI resources, it is necessary to predict whether a given HIS specifically geared towards motivating patient loyalty is likely to be adopted. The purpose of this study is to reveal the factors that comprise HISPL and to modify the Unified Theory of Acceptance and Use of Technology (UTAUT) model to help predict the likelihood of an HISPL to be fully adopted by HSI staff. The results revealed that pertinent HISPL factors are capability, configurability, ease of use/help desk availability and competence (EU), and accessibility/shareability (AS). Using these factors, the UTAUT model was modified to fit the specific needs of HISPL. The modifications are theoretical and will have to be validated in future empirical studies.

In this article, the nature and fundamentals of the theory of "three-layer interpretation of the "Holy Quran" have been studied.First, the theory is defined and comprised three layers: historical, transhistorical and modern.The historical layer has been considered as the understanding of the verses of the Qur'an by Arabs of Hejaz during the holy Prophet (PBUH). To identify such an understanding, one must refer to the promises of those people, the most important of which are the appearance and context of the verses, similar verses, the personality of the Qur'an, the events of that era, the culture and history of those people and the covenants. The transhistorical layer is considered to be an epistemology that is accepted among all human races, achieved by abolishing the temporal-spatial features of the revelation of the Qur'an.The modern layer is the adaptation of the issues, needs and requirements of the present to the same common human knowledge.Some of the most important principles of this theory, which are discussed in this article, : being customary, spoken, gradual, historical ,marginalized on one hand, and the evolution of ethnic requirements, the necessity to resolve the apparent conflict between the Qur'an and science and modernity on the other hand.

One of the important issues in enjoying Quranic verses, is the fact that which instruments can be used to understand Quran better and which obstacles should be removed to achieve this goal without any mistakes.Imam Khomeini and Professor Tabatabaee who are among the greatest thinkers and philosophers of Shi’a world believed that comprehension of Quran has outstanding significance .Thus, in this study, aiming at defining instruments and obstacles of comprehension of Quran , the viewpoints of the mentioned remarkable thinkers were discussed and finally the research led to the point that both Quran interpreters attempted to define related effective tools and indicated the obstacles on the way. The mentioned tools instruments can be categorized into two groups:Intercontextual and out_of_ context: some of the most important tools are as follows: paying attention to Arabic syntax and morphology compotability of verses, conceptual and structural coherence (regarding similar and definite verses),unique goal of the whole Surah. Enjoying virtue and inner purification, reflection and meditation in Quran, attention to interpretations and acquaintance with holy Quran

There is a difference of opinion among Quranic interpreters In interpreting verse “Qāla Rabbi ʾArinī ʾUnẓur Ilayk Qāla Lan Tarānī”(Q.7:143)[1] regarding the belief of Prophet Moses (pbuh) concerning the possibility or impossibility of seeing God at the time of saying this and they are divided into two categories. The first group believes that this verse shows that Prophet Moses (pbuh) in his words, considered it possible to see God, which is divided into five sets, each of them with their own reason. The second group of commentators, believe that Prophet Moses (pbuh) considered it impossible to see God and is divided into four sets according to their reasons. This study, by examining the opinions and reasons of the commentators and relying on the relationship between the verses and the words of this verse, will show that the request to see God from Prophet Moses (pbuh) knowing its impossibility, and only out of enthusiasm of hearing the word of God, was just for more love.

Properly inves tigating the potential of nature in the formation of architectural concepts needs a theoretical framework in which its analytical components can explain the methods of utilization of nature. Although some attempts have been made in this regard, considering the missing elements, there is s till a significant gap in the literature and a s tudy for introducing a more comprehensive theoretical framework has yet to be conducted. The aim of this s tudy is, therefore, firs tly, to present a theoretical framework that can explain the role of nature in the creation of architectural concepts by its detailed factors and, secondly, to apply this framework for inves tigating nature-inspired works of Toyo Ito. Accordingly, this documentary paper is based on a theoretical approach supported mainly by the outcomes of a literature review and case s tudy analysis, which utilizes the descriptive-analytical method. For the case s tudy part, projects were selected from various scales and functions to ensure proper evaluation. Both qualitative and quantitative tactics have been used in data analysis. Findings demons trated that the highes t rate in regards to the itemized factors of the Theoretical Framework of the s tudy relates to ‘Integration of natural elements in spatial articulation’ and the lowes t rate corresponds to ‘Usage of material in their raw and brutal s tate’. Moreover, though the highes t level of utilization of nature among the cases, is related to ‘Grin Grin’, a large-scale project, yet considering all the frequencies, it can be argued that the larger scale does not necessarily imply the higher frequency.
