Data science has become a dominant tool in many different disciplines. Many methods and approaches are available and can be used in analyzing data. Network science approach is currently considered a powerful tool that is able to visualize and analyze complex data through investigating the relations among data objects. This kind of methods considers data as nodes that are connected by edges among them, and these connections are created based on a particular strategy. In this work, we generate a network model for the Iraqi parties using the IHEC public dataset. The model consists of nodes and edges connecting them. The performance of the generated network model was evaluated using two-level of measurements; Network-Level measurements (i.e., density, average degree, degree distribution, average path length, and average clustering coefficient) and Node-Level measurements (i.e., betweenness centrality and degree centrality). The visualization and the analysis of the network showed interesting facts about the collaboration patterns among the Iraqi parties. This work also showed that network science is useful in analyzing complex and highly related data. It can also reveal some hidden patterns that might be existed within the data.

In software engineering, documentation is considered the best way to distinguish the main functions of the software. The lack of software documentation may lead to consuming time and effort during the software design phase, which finally affects the quality of software. For instance, without proper documentation, the software maintainability index would never get a reasonable mark. The research has been progressive originally as a resilient concept, once the concept is proved to be developable in the Software Development Life Cycle (SDLC), the finishing product will be started to improve with satisfactory documentation. Also, software responsibility has caused complications, such as high costs of software repairs and inefficient process of knowledge transmission between developers. As a Software Reverse Engineering (SRE) method, this work uses a combination of an automatic class diagram creation tool with some manual tweaks, as well as source code analysis and comfortable interviews, to recover the product's design principles and requirement use cases. As a result, two documents will be produced: a Software Requirements Specification document and a Software Design Document

Software code clones refer to the same part of code that appears in different places. Software clones (with or without edits) may occur during the software development for the same requirements. This copy and paste may be done on different levels (file, class, and method). Despite this process reduces the time and effort required to build the software but on the other hand, it may increase the cost and effort required to maintain the software. Also, may lead to bugs propagation when the bug occurs in the original copy of code. For this reason, many tools for code clone detection are implemented in the last 20 years to detect different kinds of clones (kind1, kind 2, kind 3, and kind 4) using different methods for different programming languages (Java, C, C++…etc). This paper explains: what are software clones, their kinds, and the methods used to detect them. It contains also a list of researches in this field till Jan 2022.

Mixed waste from office paper (MOW) is an excellent source of low-cost, high-quality fiber for the papermaking industry. The limitations in the application of conventional deinking to such paper are related to the negative environmental impacts that chemical substances can cause, which is why deinking in a neutral medium is receiving increasing attention. This study focuses on investigating the effect of the application of the amino acids Aspartate Glutamate and Asparagine, in the deinking of office paper, using a flotation column on a laboratory scale.The methodology involves the sample preparation, a pretreatment, flotation, the manufacture of paper, microscopy analysis, and finally the evaluation of optical properties. Different doses for each of the amino acids and of the mixture of the three were tested, at different conditions of temperature and pH in the pretreatment.The best optical characteristics were obtained when using the mixture of the three amino acids at 0.6% on a dry weight basis of the paper to be deinked, proposed in this study, with 90.8% whiteness. From scanning electron microscopy analysis, no superficial damage to fiber morphology is observed in any of the fiber samples after deinking.

In smart cities, it is believed that there exists an impact of the relation between the movement patterns of mobile nodes from one side, and their distribution from the other side, on the overall performance of the smart city. This work tries to investigate this kind of relation using simulations. To this end, experiments were designed using a variety of parameters. Different distributions were used as well as a mobility model with a routing protocol. Four kinds of experiments were designed, each of which includes different settings. The simulations were carried out and the results were obtained and then analyzed. The performance and the stability of these experiments were investigated. The results showed interesting facts about the simulations. The results of this research can be of benefit to smart city researchers. It will also be of interest when it comes to developing optimal strategies for spreading advertising in a smart environment.

Coverage area in dynamic networks is considered an important issue that affects their general performance. It also affects the delay time when exchanging data and the consumption of resources in the network. Moreover, the coverage area issue in dynamic networks is directly affected by the distributions of nodes within the environment. Movement patterns may also affect the performance when it comes to coverage area. Therefore, this work develops a method that simulates different scenarios. These scenarios include a variety of settings and parameters that are believed to affect the coverage area issue of dynamic networks. These experiments enable network developers to be aware of the optimal conditions that maximize the coverage area of dynamic network nodes and eventually improve the overall performance of the network. Three distributions are used in the experiments namely, Cauchy distribution, Power-Law distribution, and Normal distribution. Also, the simulations incorporate the correlation mobility model for nodes dynamics. The findings show that Cauchy distribution is not appropriate for simulating dynamic networks due to the large uncovered areas by nodes communications. Also, the stability of an approach is considered an important factor when measuring the performance of a dynamic network. The results of this research are important to avoid wasting network resources.

The metaheuristic optimization algorithm is used to explain a large region solution space. One of these algorithms is a grasshopper which divides the search process into exploitation and exploration. This article focuses on research efforts directed at gaining a clear understanding of the behavior of grasshoppers and it is using optimization algorithms. It is concluded that the benefits have been effective in answering global unrestricted and restricted optimization issues, easy development, high accuracy, and obtaining a good solution. However, the disadvantages of the GOA algorithm are simple to fall into local optimum and slow convergence speed.

This study was achieved to find an optimum design for eggs incubator where the resources of this field is very limited. The most important factors were putted forward including the dimensions of each element. The energy required in operation periods was calculated. Where the operation time consists of two periods (the first period takes 17 days and the second period from the 18th day to the 21 day). The results shown an excellent efficiency, however, some eggs were failed due to some physiology justifications. Some of eggs were taken longer time to hatch due to long storage time or the eggs were in a bigger size.

Public aquariums as part of the tourism industry are ted by the pandemic conditions which have caused a decline in visits. Concerns are also still looming over whether there will be another closure policy or a change in consumer behavior in the future. Therefore, Public Aquarium had to change its products and services to adapt to the new habits. This study aims to give recommendation design content on digital products developed as an alternative product form offered to consumers. The research began with a customer survey, followed by an analysis with two levels of QFD involving interviews and discussions. As a result, customers expect digital products that encourage learning about aquatic animals that develop interactive and engaging content. Public aquariums can design educational and entertainment content to convey their collection products into information and interactive technical functions that add value to consumer interest in the content provided.
