Abstract: Background: In spite of the fact that computers continue to improve in speed and functions operation, they remain complex to use. Problems frequently happen, and it is hard to resolve or find solutions for them. This paper outlines the significance and feasibility of building a desktop PC problems diagnosis system. The system gathers problem symptoms from users’ desktops, rather than the user describes his/her problems to primary search engines. It automatically searches global databases of problem symptoms and solutions, and (...) also allows ordinary users to contribute exact problem reports in a structured manner. Objectives: The main goal of this Knowledge Based System is to get the suitable problem desktop PC symptoms and the correct way to solve the errors. Methods: In this paper the design of the proposed Knowledge Based System which was produced to help users of desktop PC in knowing many of the problems and error such as : Power supply problems, CPU errors, RAM dumping error, hard disk errors and bad sectors and suddenly restarting PC. The proposed Knowledge Based System presents an overview about desktop PC hardware errors are given, the cause of fault are outlined and the solution to the problems whenever possible is given out. CLIPS Knowledge Based System language was used for designing and implementing the proposed expert system. Results: The proposed PC desktop troubleshooting Knowledge Based System was evaluated by IT students and they were satisfied with its performance. (shrink)

The article is devoted to comparative analysis of metaphysical studying of a Samaritan theologian and exegete al-Ghazzāl ibn ’Abū Surūr (d. after 1755) and a representative of Shiraz Illuminationism school, philosopher, astronomer and mathematician Ghiyāth al-Dīn Manṣūr al-Dashtakī (d. 1541). Based on a scrupulous analysis of the doctrines by al-Ghazzāl and Ghiyāth al-Dīn, the author comes to the conclusion about their genetic link – supposedly, as a result of perception of Illuminationist systems in the Middle East in 17th–18th centuries. It (...) is noticed that a Samaritan exegete, acquainted with Arab-Mus­lim philosophic literature as a prominent specialist, taught about ontologistic primacy of light, metaphysical nothingness of dark, stated about light nature of action and com­plete dependence of matter on the will of the Creator. Separately it discusses the desire of both authors to deconstruct the classic for Arabic philosophy thesaurus. It is expressed in the convergence of the categories ‘movement’ (ḥaraka) and ‘action’ (fi‘l), as well as in the consistent replacement of the concept ‘self’ (ḏāt) with the concept of ‘light’ (nūr). The differences between the concepts of al-Ghazzāl and ad-Dashtakī are also discussed separately: while the first author inscribes the opposition ‘light – dark’ in a creation onto­logical context, the latter professes belief in the ‘total unity’ of the lights, their eternity and uncreation. The research is preceded by a short excursion into the history of Samari­tan theology of the 11th–18th centuries. Moreover, the article provides the description of unpublished documents which served the textological basis for the author’s work – in particular, the manuscript of al-Ghazzal’s interpretation of Genesis and Exodus ‘Dis­persion of the darkness [covering] the secrets of the Giver’ (Kashf / Kāshif al-Ghayāhib ‘alā Asrār al-Wāhib; British Library, Add MS 19657).
