Optimum Feature Selection for Recognizing Objects from Satellite Imagery Using Genetic Algorithm

Object recognition is a research area that aims to associate objects to categories or classes. Usually recognition of object specific geospatial features, as building, tree, mountains, roads, and rivers from high-resolution satellite imagery is a time consuming and expensive problem in the maintenance cycle of a Geographic Information System (GIS). Feature selection is the task of selecting a small subset from original features that can achieve maximum classification accuracy and reduce data dimensionality. This subset of features has some very important benefits like, it reduces computational complexity of learning algorithms, saves time, improve accuracy and the selected features can be insightful for the people involved in problem domain. This makes feature selection as an indispensable task in classification task. In our work, we propose wrapper approach based on Genetic Algorithm (GA) as an optimization algorithm to search the space of all possible subsets related to object geospatial features set for the purpose of recognition. GA is wrapped with three different classifier algorithms namely neural network, k-nearest neighbor and decision tree J48 as subset evaluating mechanism. The GA-ANN, GA-KNN and GA-J48 methods are implemented using the WEKA software on dataset that contains 38 extracted features from satellite images using ENVI software. The proposed wrapper approach incorporated the Correlation Ranking Filter (CRF) for spatial features to remove unimportant features. Results suggest that GA based neural classifiers and using CRF for spatial features are robust and effective in finding optimal subsets of features from large data sets

Enhancing transient stability of power systems using a resistive superconducting fault current limiter

The electricity demand keeps increasing with development and time, which leads to the need to install more generating units in the grid. Therefore, the fault current levels will rise above the limits of the electrical equipment, particularly when the electric grid becomes meshed and interconnected with neighboring networks. Consequently, the electrical equipment needs to be replaced or use a method that will decrease the fault current to be within the permissible boundaries. The existing solutions such as neutral impedance, current limiting reactor (CLR), and bus splitting have negative impacts on the electric grid. The superconducting fault current limiter (SFCL) appears to be a promising solution. In this paper, the resistive SFCL is proposed to enhance the stability of the interconnected power system. The two-area system is used as a case study for the interconnected power system. Also, the optimal value and locations of the resistive SFCL are analyzed. The results show that the system will remain stable without tuning the power system stabilizer (PSS)

A Framework for Selecting Architectural Tactics Using Fuzzy Measures

Software architects cannot avoid the consideration of quality attributes when designing software architecture. Architectural styles such as Layers and Client-Server are often used by architects to describe the overall structure and behavior of software. Although an architectural style affects the achievement of quality attributes, these quality attributes are directly performed by design decisions called architectural tactics. While the implementation of an architectural tactic supports a specific quality attribute, it often enhances or hurts other quality attributes in the software. In this paper, a framework for selecting the most appropriate architectural tactics according to their best achievement of the required levels of quality attributes when developing transaction processing systems is proposed. The proposed framework is based on fuzzy measures using Choquet Integral approach and takes into account the impact of

ISO9126 BASED SOFTWARE QUALITY EVALUATION USING CHOQUET INTEGRAL

Evaluating software quality is an important and essential issue in the development process because it helps to deliver a competitive software product. A decision of selecting the best software based on quality attributes is a type of multi-criteria decision-making (MCDM) processes where interactions among criteria should be considered. This paper presents and develops quantitative evaluations by considering interactions among criteria in the MCDM problems. The aggregator methods such as Arithmetic Mean (AM) and Weighted Arithmetic Mean (WAM) are introduced, described and compared to Choquet Integral (CI) approach which is a type of fuzzy measure used as a new method for MCDM. The comparisons are shown by evaluating and ranking software alternatives based on six main quality attributes as identified by the ISO 9126-1 standard. The evaluation experiments depend on real data collected from case studies

Evaluating User Interface Management Systems based on Quality Attributes and Unit Operations

Software architecture is an essential early stage in the software design process. In this stage, the architect should give the quality attributes a special consideration because a good level of meeting these attributes can be performed by well-designed architecture. This means that there is a close relationship between quality attributes and software architecture. However, quality attributes can be achieved through the appropriate application of a set of unit operations. A unit operation is a systematic designing operation that can be applied directly to system architecture. Architectural styles (patterns) include high level design decisions that address quality attributes. Many general architectural styles are defined in the literature. For the domain of user interactive systems there are many architectural styles that address some important quality attributes. In many cases, it is essential to evaluate software styles in terms of their achievement of the required quality attributes by analyzing the relationships between these attributes, unit operations, and styles. This evaluation can help and facilitate the process of selecting a specified style. In this paper the authors propose a structured quantitative evaluation method to show a rank of four wellknown user interface management systems (UIMSs) in terms of their supporting a set of six important selected quality attributes

Gradient-Free Federated Learning Methods with l1l_1 and l2l_2-Randomization for Non-Smooth Convex Stochastic Optimization Problems

This paper studies non-smooth problems of convex stochastic optimization. Using the smoothing technique based on the replacement of the function value at the considered point by the averaged function value over a ball (in $l_1$-norm or $l_2$-norm) of small radius with the center in this point, the original problem is reduced to a smooth problem (whose Lipschitz constant of the gradient is inversely proportional to the radius of the ball). An important property of the smoothing used is the possibility to calculate an unbiased estimation of the gradient of a smoothed function based only on realizations of the original function. The obtained smooth stochastic optimization problem is proposed to be solved in a distributed federated learning architecture (the problem is solved in parallel: nodes make local steps, e.g. stochastic gradient descent, then they communicate - all with all, then all this is repeated). The goal of this paper is to build on the current advances in gradient-free non-smooth optimization and in feild of federated learning, gradient-free methods for solving non-smooth stochastic optimization problems in federated learning architecture.Comment: in Russian languag

WAR CRIMES IN GAZA STRIP FROM YEAR 2008 2021: INDIVIDUAL CRIMINAL RESPONSIBILITY UNDER THE LEGAL FRAMEWORK OF ROME STATUTE OF THE INTERNATIONAL CRIMINAL COURT

From the end of the year 2008 to 2021, Israel committed four wars in the Gaza Strip. These wars were known as Operation Cast Lead in 2009, Operation Pillar of Cloud in 2012, Operation Protective Edge in 2014, and Operation Guardian of the Walls in 2021. The destructive impacts on vital facilities in Gaza, including schools, universities, mosques, hospitals, and United Nations Relief centers, as well as the killings of thousands of innocent civilians by Israeli forces, are visible evidence of a serious violation of the principle of distinction, a basic principle provided under the international humanitarian law conferring protection upon the civilians during armed conflicts. The accession of Palestine to the Rome Statute of the International Criminal Court on crimes. This paper aims to analyze the position of individual criminal responsibility committed during the above-mentioned wars, regulated under the Rome Statute of the International Criminal Court and other relevant international conventions. In analyzing the data from primary and secondary sources, this paper applied doctrinal legal research and qualitative approaches. This paper concludes that the Rome Statute of the International Criminal Court associated the individual criminal responsibility for war crimes by systematically determining the extent of participation, namely: (1) commission; (2) ordering/instigating; (3) assistance; and (4) contribution to a war crime as a group crime. Thus, Israeli military leaders ought to be held liable for the commission of war crimes in accordance with Article 8 of the Rome Statute of the International Criminal Court. The pretexts of the Israeli occupation to be exempt from criminal responsibility should be rejected according to the state of legitimate defense

The Politics of Social Structures in the Palestinian Case: From National Resistance to Depoliticization and Liberalization

This article examines the role of Palestinian civil society organizations in resistance struggles against Israeli military occupation in the 1970s and 1980s. The research focuses on the civil society transformation and shift from national resistance in the politically motivated framework of Israeli–Palestinian conflict of the 1970s and 1980s to internal and depoliticized processes in the 1990s. The overall purpose of this study is to provide knowledge about the role of civil society organizations in Gaza and the West Bank in the Palestinian national struggle and promote a deeper understanding of the changing role of Palestinian civil society following the Oslo peace process in the 1990s. The research methods are based on a supportive and integrated combination of theory and field research including interviews with civil society and academic representatives. The main findings and conclusions suggest that the transformation of Palestinian nationalist and secular grassroots organizations and the shift towards depoliticization and liberalization in the 1990s is the result of the Oslo peace process and the subsequent creation of a Palestinian “liberal civil society” in response to the requirements of international donors and their liberalization agenda

Peacebuilding and challenges to secular and nationalist Palestinian civil society organizations in Gaza

THESIS 10702This study focuses on the themes of peacebuilding and civil society. It explores the role of secular and nationalist civil society organizations in peacebuilding at the local and political levels in Gaza. For over 20 years, Israeli-Palestinian negotiations have failed to achieve a just solution and settlement for Palestine. Furthermore, the international community has also been unsuccessful in responding positively to the Palestinian issue. Little attention has been given, however, to those local peacebuilding efforts in Gaza that strive to support human rights and just peace
