3. Microstructure, Strength, and Physical Properties of MetakaolinBased Geopolymer Mortar
The major starting elements for the geopolymer matrixes synthesis were alkali activators and aluminosilicate materials, with the former being kaoline, fly ash or slag, and the latter having sodium silicates (Na2SiO3) and sodium hydroxide (NaOH) respectively. Metakaoline was used as one of the raw materials in the geopolymerization process in this research .The influence of NaOH concentration and alkaline-liquid ratio on the characteristics of metakaoline-based geopolymer products will also be discussed in this article. Geopolymer mortar cubes sized 50mm x 50mm x 50mm.The alkaline liquid to metakoline ratio is 0.6, and the temperature of cure is kept at 70°C for 5h in oven with hot air, followed by 28 days in the sun.The effect of NaOH concentrations ranging from 8 to 14 M and alkaline-liquid ratio are (2 and 2.5). Finaly we replaced 20%of metakaolin with fly ash to study influence of fly ash and compare between two raw material. Mechanical testing such as compressive strengths and flexural strengths And NDT such as UPV, water absorption. Thermal conductivity and Microstructural investigations have been used to describe it, such as (XRD) and (SEM) are used to estimate GPMs.Based on the findings, the optimum NaOH concentration (14 M) at which geopolymer exhibits the best mechanical properties was determined based on the research findings.

4. ARABIC SIGN LANGUAGE TO TEXT AND SPEECH TRANSLATION USING CONVOLUTIONAL NEURAL NETWORK AND PYTORCH
Hard of hearing people utilize use gestures communication to speak with each other and with the overall population. Particularly, when a consultation individual needs to talk with a hard of hearing individual, a translator is normally vital. Visual communication through signing acknowledgment is a quickly advancing field of PC vision research. In this exploration doing Create a work area application utilizes PC's webcam to decipher the Arabic communication via gestures, where the motions are caught to the Arabic letters and made an interpretation of them into text and transform the content into a voice. By using convolutional neural network (CNN). Convolution neural network is viable in handling PC vision issues and ready to find exceptionally required highlights when satisfactory preparing, where the profound convolutional neural network has been applied to the profound learning in the Python language with Pytorch innovation.
