Quality Control in Games Development
No full textThe purpose of this thesis was to provide more information regarding the role of quality control in game development to game industry professionals, game development start-ups and potential employees of this field. There are several misconceptions about this profession and this thesis contains information regarding the impact quality control has in games development.
The motivation to conduct this research and write this thesis comes from the author’s work experi-ence in testing games in a game development studio. From personal experience, the author had some misconceptions about this profession as well, which were cleared when she began working as a tester. The information regarding quality control is sparse compared to other aspects of game development.
This thesis was written using a qualitive research method where the sources were from data col-lection, online survey, printed and online literature. The results of this research outlined the dif-ferent methods of testing processes the quality control department must undergo to produce a feasible outcome for a game.
Quality control is one of the main aspects of game development, since this activity results in the discovery of bugs, establishing a defect database, and most importantly, the approval for a viable game to be published. Quality control does not cease when the game is released but continues postproduction as well.
The conclusion of this thesis report is that quality control is vital to the development of a game, although some game companies still do not view it as an important aspect for their games. In addition to hopefully clearing the misconceptions of people who want to follow this career path due to misunderstanding of the skills and knowledge required to be a games tester. Furthermore, an attempt to settle the mistaken belief that quality control is not a viable career path and people beginning at this position to gain a position in other departments of game development.
The author has signed a non-disclosure agreement with her employer. All information in this thesis that has been gathered from survey responses are taken from game industry professionals and are respectively referenced. Survey questions asked their opinions on quality control and when they feel testing is required most, whether quality control is required in start-ups, automated testing, and testers responsibility in detecting fun factor of the game

The Freedom of information in the government information centers: a field study
No full textتتناول هذه الدراسة قضية حرية تداول المعلومات ورصد الوضع الراهن في مصر، من خلال الكشف عن ضوابط وآليات إتاحة وتدفق المعلومات داخل مراكز معلومات الوزارات. فضلا عن رصد أراء واتجاهات المستفيدين تجاه ذلك. واعتمدت الدراسة على المنهج المسحي الميداني.
ومن أهم النتائج التي توصلت إليها الدراسة غياب وجود آليات وضوابط واضحة ومعايير محددة وموحدة تتبعها مراكز معلومات وزارات الحكومة المصرية في التعاطي مع إتاحة المعلومات. وإنما الأمر يرجع إلى اجتهادات القائمين على إدارة كل مركز على حدة، وذلك ما دفع الغالبية العظمى من المستفيدين إلى المطالبة بضرورة إصدار قانون لحرية تداول المعلومات ووضعه على رأس قائمة الأولويات لما له من أهمية كبيرة في تنظيم انتقال المعلومات دون الاحتكام للمعارف الشخصية والتوجهات الأخرى.This study deals with the issue of freedom of information circulation and monitoring the current situation in Egypt, through the disclosure of controls and mechanisms for providing information flow and information within the information centers of the ministries. In addition to monitoring the views and attitudes of the beneficiaries towards this. The study relied on the field survey method.Among the most important results of the study are the absence of clear mechanisms and controls and specific and unified standards to be followed by information centers of the Egyptian government ministries in dealing with the availability of information. Rather, it is up to the diligence of those in charge of managing each center separately, which led the vast majority of beneficiaries to demand the necessity of issuing a law for the freedom to circulate information and place it at the top of the list of priorities because of its great importance in organizing the transmission of information without invoking personal knowledge and other directions
Book Review: Marwa Al-Sabouni, The Battle for Home. Memoir of a Syrian Architect
No full textWith the pictures of bombing, ruins, and death coming from Syria, Marwa Al-Sabouni looks at the role of architecture and planning in the protracted conflict. In a first-hand account from the war-ravaged city of Homs, she tells the story of her native city, illustrated by her own drawings and autobiography. The book consists of six chapters, or six battles, and brings together the role of politics of urban planning, heritage, forced displacement and refugee crisis. The foreword of the book is written by the British philosopher Sir Roger Scruton, followed by a preface to the new edition by the author, and an introduction. The final part of the book includes, in addition to notes and acknowledgement, a historical timeline with the main events in Syria’s modern history, and a discussion guide for a deeper understanding of the Syrian society

Thermophysical properties enhancement of octadecane using reduced graphene oxide and graphene oxide nanoplatelets
No full textAutomatic Control of a Mobile Manipulator Robot Based on Type-2 Fuzzy Sliding Mode Technique
No full textIn this paper, an automatic control method based on type-2 fuzzy sliding mode control for a mobile arm robot is presented. These types of robots have very complex dynamics due to the uncertainty of the arm parameters and the mobility of their base, so conventional control methods do not provide a suitable solution. The proposed method proves convergence with Lyapunov theory, and its convergence is mathematically guaranteed. A type-2 fuzzy system is responsible for approximating unmodulated dynamics, nonlinear terms, and uncertain parameters. In simulations, the performance of the proposed method with different situations, including uncertainty in arm parameters, uncertainty in mobile robot parameters (arm robot base), uncertainty in load, as well as indeterminacy in modeling have been applied. The comparison with two conventional controllers shows the efficiency and superiority of the proposed method
