It is anticipated that automobiles operated by humans will continue to be a common sight on the roads for the foreseeable future; &nbsp;nevertheless, it is possible that autonomous vehicles may coexist in the same traffic environments. In order to keep traffic moving smoothly throughout the various sorts of mixed-use zones, autonomous vehicles (AVs) need to have driving rules and negotiation abilities that are analogous to those used by humans. In order to develop driving abilities that are comparable to those of humans, model-free deep reinforcement learning is used to simulate the actions of a skilled human driver. In this simulation, the difficulty of avoiding static obstacles on a two-lane roadway is investigated .</p> Hayder Salah Abdalameer, Ali Abid Al-Shammary ##submission.copyrightStatement## Fri, 12 Aug 2022 09:04:31 +0000 Interactive Situated Autonomic Multi-Agents System-Comprehensive Survey <p>Multi-Agent Systems (MAS) are made up of autonomous entities called agents. Agents collaborate to complete tasks, but their intrinsic capacity to learn and make independent judgments allows them to be more flexible. Agents learn new contexts and behaviors through their interactions with other agents as well as the environment. Agents then exploit their knowledge to determine and carry out an action on the environment in order to accomplish their assigned objective. Because of its versatility, MAS is well suited to solving issues in a wide range of areas, including computer science, civil engineering, electrical engineering, etc. Developing cooperative MAS necessitates tackling a variety of issues, especially coordination among agents. Consequently, this paper discusses several interaction ways among agents in many disciplines.&nbsp; Index Terms—multi-agent system(MAS), Robotic Process Automation, situated agents, interaction.</p> Mohammed Ali, Ali Obied ##submission.copyrightStatement## Fri, 12 Aug 2022 09:35:08 +0000 Pre Diagnosing the Stroke Using Deep Learning <p>&nbsp;&nbsp; Stroke is a long-term disability that affects people all around the world. A stroke deprives the brain of oxygen and nutrients, causing brain cells to stop working or die. Radiologists classify them using Magnetic Resonance Imaging(MRI) of the brain for people with stroke. We've presented a solution based on Deep Learning Algorithms such as Convolution Neural Networks (CNN) and Transfer Learning (TL). We divided MRI into two categories in this work (stroke and normal). In this paper, a 4-layer CNN is used from beginning to end with a modification of the EfficientNetB0 network by adding two layers to make the extracted features more diverse. &nbsp;CNN and pre-trained EfficientNetB0 were used to train our architecture. The EfficientNetB0 achieves an accuracy of 99.6%, while CNN achieves an accuracy of 99.2%. The newly created EfficientNetB0 could be a highly important decision-making tool in stroke research and brain diagnostic testing. As a physician's assistant, the proposed method works.</p> Makarem S. Atshan, Zainab N.

The photos are usually taken in nature, like forests, cities, streets, etc., and are generally accepted in terrible weather conditions, especially fog. This is because the light is a critical factor in obtaining clear images, assuming the cameras' quality. The presence of various types of haze (smoke, fog, and dust) reduces the light rays that are reflected from the scenes to be photographed, so removing the haze was the researchers' primary concern. Moreover, many computerized devices use these cameras and imaging devices in various fields. Through this research, we will mention a number of those applications that use this biotechnology "dehazing."</p> Kholud A .Karoon, ainab N.

Large datasets are required in training process, and whole of such data must be centralized for be handled by such techniques. It is sometimes impossible to collect and distribute patient data on a centralized data server because of medical data privacy regulations. In this paper, federated learning (FL) is proposed, in which data is non-shareable because of patient privacy issues. Using the FL approach, we have proposed two methods of aggregation; first, which concerns ranking the weight percentage of each client, and Second average weights method. and to evaluate the suggested model, we have compared the performance of the ranking weights percentage method with the average weights of proposed CNN and pre-training (VGG-16) in the FL environment in addition to SVM and VGG-16 . The experiments result was applied on two datasets, it shows our model accuracy result is very effective when using the ranking weight percentage method as compared with other methods, it achieves accuracy (98%) on datasets (BT_large-1c) and achieve (97.14%) on the dataset (BT-large-2c).</p> Dhurgham Hassan Mahlool, Mohamed Hamzah Abed ##submission.copyrightStatement## Fri, 12 Aug 2022 10:41:29 +0000 Statistical Analysis of Aluminum Doped Titanium Dioxide <p>In the present research, titanium dioxide and Al nanoparticles were purchased from a Chinese company, then the aluminum materials were added in five ratios that are (0, 1, 2, 3, 5) wt.%.

The European Foundation for Quality Management (EFQM) has developed and verified the Excellence Model (EFQM) as the gold standard for measuring an organization's pursuit of excellence. An updated integrated strategy that incorporates fuzzy logic into the EFQM model is a powerful tool for boosting an organization's overall performance. This research utilizes the EFQM paradigm to suggest a novel and all-encompassing strategy for enhancing corporate performance. We looked at the specific situation of the Iraqi Oil Tanker Company to determine how doable the strategy actually is. With the use of the EFQM framework developed by the European Foundation for Quality Management, we have shown how useful this tool is for pinpointing both strengths and places for development. The RADAR Logical Method and Fuzzy-Based Strategy were utilized in this case study (EFQM). Matlab was used to apply the suggested technique for assessing the performance of the Iraqi Oil Tankers Company during a three-year period.</p> Miami Hamid Khalif, Kareem Radi Hassan ##submission.copyrightStatement## Sat, 24 Sep 2022 12:27:33 +0000 Machine Learning-Based Effective Detection Scheme of Fake News <p>Today, extremely large amounts of false news are consistently uploaded by malevolent people with fraudulent intentions, endangering democracy, justice, and public confidence while having highly harmful social impacts on both individuals and society. Due to the inherent uncontrollable posting processes of social media sites (such as Facebook, Twitter, and Snapchat), this is particularly pertinent to them. The need for earlier false news identification has considerably fueled efforts in academia and business to create more accurate fake news detection techniques. Unfortunately, there isn't much information available regarding how news spreads. There are benefits and drawbacks to relying on social media to follow the news. Social media platforms do make it possible for information to flow swiftly among users. However, these websites could be used to disseminate "fake news," which is low-quality content that contains errors. The widespread dissemination of false information has an extremely damaging effect on both people and society. As a result, the detection of fake news posted on numerous social media platforms has recently emerged as a highly regarded field of study. In this paper, an effective detection scheme of fake news based on the commonly utilized techniques of machine learning has been presented. This proposed scheme involves diverse phases; Dataset preprocessing phase, extracting the phase of the feature, and Naive Bayes (NB) and K-nearest Neighbor are used in the categorization step (KNN). The obtained results in this presented scheme exhibit that the utilization of the NB classification technique exceeds the K-NN classification technique with an accuracy of 94% using the same dataset.</p> Khalid Abood Kamel, Jumana Waleed ##submission.copyrightStatement## Sat, 24 Sep 2022 12:32:58 +0000 On Negative Logarithm Semigroup <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In this work, we introduce certain type of semigroup, namely (<strong>Negative Logarithm semigroup</strong>) ,in the functional analytic study of differential equations.
