The MNIST database will be used for this specific problem, which is the recognition of handwritten digits from one to nine. It is a good idea to use more examples than contrasted ones to compare these frameworks because this database is the subject of active research at the moment and has produced excellent results. However, in order to be trained and deliver accurate results, neural networks need a sizeable amount of sample data, as will be covered in more detail later. Because of this, big data experts frequently encounter problems of this nature. As the project description implies, we won't just present a standard comparison because of this; instead, we'll work to present a comparison of these networks' performance in a Big Data environment using distributed computing. The FMNIST or Fashion MNIST database and CIFAR10 will also be tested (using the same neural network design), extending the scope of the comparison beyond MNIST. The same code will be used with the same structure thanks to the use of a higher-level library called Keras, which makes use of the aforementioned support (in our case, Theano or TensorFlow). There has been a surge in open-source parallel GPU implementation research and development as a result of the high computational cost of training CNNs on large data sets. However, there aren't many studies that have been done to assess the performance traits of those implementations. In this study, we compare these implementations carefully across a wide range of parameter configurations, look into potential performance bottlenecks, and pinpoint a number of areas that could use more fine-tuning.","PeriodicalId":23142,"journal":{"name":"Tikrit Journal of Pure Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86856038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To make optimization between the candidate electrodes, seven configurations of Ni-Ti, Ti-Ti, and Ti-Ni with three KOH solutions of 10, 20, and 30 % wt (weight KOH gm/weight water gm) as an electrolyte were conducted as a cathode-anode system. The selected electrodes were examined by scanning electron microscopy (SEM) and energy dispersive (EDX) to study their surface morphology and element composition. According to experimental findings, when the cell voltage of 5 V is applied, the hydrogen production from the Ti-Ti (20%KOH) and Ni-Ti (20% and 30% KOH) electrodes reach an optimal value of 6331 cm3, which is significantly higher than the hydrogen production from the other electrodes at the same voltage. The Ni-Ti electrode with a 10% KOH content had the maximum efficiency (72%), and the Ni-Ti electrode with a 30% KOH content had the lowest efficiency (61%), both at 3V for the cell. This study demonstrates that the Ni-Ti system can be the most suitable source for hydrogen evolution rather than the other arrangements when the appropriate mixing ratio of 20 % KOH solution is prepared before the electrolysis process","PeriodicalId":23142,"journal":{"name":"Tikrit Journal of Pure Science","volume":"238 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77027535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is due to new titanium alloys consisting of non-cytotoxic substances like molybdenum (Mo), tantalum (Ta), niobium (Nb), zirconium (Zr), or tin (Sn) have advanced when treated as a cubic β-phase alloy, which has led to the investigation of Al and V free titanium alloys. When configured as a cubic β-phase alloy, they exhibit abnormal corrosion resistance as well as decreased elasticity moduli that are comparable to the substance of the bone they are repairing. \u0000This work uses synchrotron x-ray diffraction to calculate the unit cell volume of beta-phase gum metal \u0000(Ti–23Nb–0.7 Ta–2Zr–1.2O-TNTZ-O system) at pressures 50, 45, 24, and 40 GPa respectively. The Murnaghan, Viet and Birch-Murnaghan equation of state has been applied using the bulk modulus measurement it was about 88.7GP . Additionally, applying the same technique, the bulk moduli of Ti-7.5Mo-1O, Ti-7.2Mo, and Ti2448 have been determined to be 116.1, 50.2, and 116.2 GPa, respectively. The Ti-7.2Mo system has a below-average bulk modulus when compared to all other alloys. For biomedical applications like hip and human bone replacement, which will be the subject of the study, it would be most appropriate to change the (Ti-xMo-xNb-xTa) alloy and investigate its mechanical properties.","PeriodicalId":23142,"journal":{"name":"Tikrit Journal of Pure Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88252757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
