This task showed its importance in the natural language processing NLP field and it helps people with specific learning difficulties to access Arabic web content. To tackle the problem, we suggest a letter-based encoder-decoder that uses previous deep learning attention models known as Luong attention. The training of the models knew unstable loss. And, as was expected — from the proposed models — the model that uses local predictive attention achieved the best word and letter error rates. The best-achieved diacritic error rate in the test data is about 26.80%. Nevertheless, the models need improvements in future work.</p> Ali Mijlad Yacine EL YOUNOUSSI Copyright (c) 2023 Ali Mijlad, Yacine EL YOUNOUSSI 2023-01-25 2023-01-25 3 1 653 662 Summaries of Causes, Effects and Prevention of Solar Electric Fire Incidents <p>Currently the number of fire incidents involving photovoltaic (PV) systems are increasing as a result of the strong increase of PV installations.

The process of cooking can involve several phase transformations. Different terminologies used in cooking like steaming, frying, broiling, grilling can be related to rate of heat transfer. The taste of food can be considered as an output of time temperature transformation being cooked. The product of time, temperature and nature of medium used for cooking can decide the quality of food. Understanding the concept of thermal conductivity, specific heat and thermal diffusivity can lead to optimized time of cooking. Cooking can be used to demonstrate the law of conservation of angular momentum by spinning a raw egg and a boiled egg.</p> Subramaniyan Alagappan Copyright (c) 2023 Subramaniyan Alagappan 2023-01-25 2023-01-25 3 1 673 677 Review on waste water reuse for irrigation towards achieving environmental sustainability <p>Even though water makes up around 70% of the earth's crust, just a small portion of it is suitable for terrestrial life. Water is essential for life. The small percentage of freshwater with low salt concentration in the Antarctic and Arctic (68.7%) is only 2.5% of the total water stock in the hydrosphere and is largely in the form of ice and permanent snow cover. This writing serves as a review. Journals, publications, and earlier project works pertinent to the subject at hand were thoroughly examined and strategically sampled. To gather the data needed for the paper's creation, many works were examined and summarized. Agriculture is a large consumer of wastewater globally. It is believed that finding suitable irrigation resources is crucial for protecting natural water bodies and ensuring food safety. Wastewater reuse has emerged as a practical option for pollution reduction when water reuse replaces effluent discharge to vulnerable surface water bodies, preserving and extending available water supplies. This is due to the difficulties associated with the discharge of untreated wastewater into the environment. As treating and utilizing wastewater for irrigation would make it easier to achieve sustainability, using wastewater for irrigation is an efficient strategy to lower costs and improve environmental health and safety in today's economy.</p> Hüseyin GÖKÇEKU Youssef Kassem Henok Seman Abubakar Ali G.
