مشکلة حقیبة المستثمر متعدد الأبعاد باستعمال الخوارزمیات المستوحاة من الطبیعة – مراجعة مقال

The backpack problem or the multidimensional investor is an important and well-known hard (discontinuous) constrained combinatorial optimization problem in operations research and optimization.Nowadays, algorithms inspired by nature have become extremely important in solving many mathematical problems, including the problem of the investor's portfolio.In order to reach the best solutions, in this research, three algorithms were used to solve this problem.The marine predator algorithm, which is a very modern algorithm, outperformed the weed algorithm and the black hole algorithm in obtaining the best solution and the least possible time.While the black hole algorithm came in the third place, although it does not need to specify any parameter of the algorithm before its work.
Obtaining Answers from Social Media Data

Summary form only given, as follows. The complete presentation was not made available for publication as part of the conference proceedings. Content posted on social media is a rich set of data from which we would like to answer a broad set of questions. As one important example, keeping users safe on social networks requires that we identify content that contains misinformation or hateful speech and remove it. Similarly, users may be interested in getting additional value from their network such as finding friends who recently travelled to a particular destination or finding out which movies their friends are discussing. The typical machine learning approach in which we develop a model for every question we want to ask works well for questions we ask constantly (e.g., find hate speech), but not for ad-hoc questions that occur infrequently. In this talk I will advocate for an approach that combines the benefits of machine learning and database-style query answering. I will illustrate this approach through the idea of Neural Databases, a new kind of database system that leverages the strength of pre-trained language models to answer database queries over text and other modalities.
Evaluation of the Main Components for Learning with Materials in Educational Platforms

Distance Education Learning for higher levels depends on multiple factors which entail pedagogical and technical dimensions. This research focused on an assessment study of materials contained in an educational platform, showing results on the factors causing significant intervention in the ways of learning in Virtual Learning Environments. The study contemplates a sampling for the educational platform operating at the Autonomous University of the State of Mexico. It was conducted following a transversal descriptive methodology, assessment of 19 independent study guides, and analyses of 13 fundamental indicators for each of them. For the research design, descriptive and correlational statistical techniques were used to analyze the foundation of the model. T tests were conducted to understand the discrepancy of those factors that should be showing a convergence. Results showed that there were areas of opportunity in terms of contents, learning activities, activity evaluation with feedback and materials content. The main inference found was that, in order to be able to build a distance educational model, the main components for learning should score a minimum of 7 out of the 10 possible points to be able to guarantee quality education materials in educational platforms. The recommendations include the prioritization of not replicating a traditional educational model deposited in virtual form, implying the support of the integration of educational materials with the Virtual Learning Environments.
Information Retrieval Based on Brazilian Portuguese Texts

Knowledge-based intelligent systems might be used in the banking sector to automate customer service. One of the ways to represent knowledge that is both understandable by humans and readable by machines is by using ontologies. Whenever a customer queries its bank regarding specific products or services, the existing knowledge modeled in an ontology might be used by a customer service chatbot to answer it in an automated way. The existing manual information retrieval process from banking specialists is laborious and time-consuming. Specialists use natural language, visual representations, and common sense, often overlooking details. It is a great challenge to make a specialist's knowledge explicit, formal, precise, and completely scalable, which is the format required by a customer service chatbot. We propose a semi-automatic approach to retrieving banking information in Brazilian Portuguese texts with minimal specialist support. By combining Natural Language Processing techniques (e.g., syntactic analysis to obtain the logical meaning of sentences based on rules and its structure) and an ontology constructor library, it was possible to build a tool that receives texts from the banking domain and constructs an ontology that knowledge-based intelligent systems can use. Specialist support is only needed in intermediate refinement steps, thus optimizing the banking specialist's time. The use cases for investments, opening a banking account, and the comparison of the proposed approach show how we reduced manual labor in the information retrieval process by a factor of 40%. Our approach can identify more information in each sentence compared to a similar method found in the literature. The resulting ontologies can be used in a chatbot that automates customer support for a large Brazilian bank.
Impact of Device Jailbreaking or Rooting on User Data Integrity in Mobile Forensics

Digital devices have become very important in most people’s lives in this world, so the usage of these devices for sure will leave traces which can solve the mystery of crimes. A forensic analyst has one goal, which is to get as much data from a device as possible. However, this goal can only be achieved when applying physical image acquisition from the device, which can reach 100% copy. There are many forensic tools that are used in forensic science, and these tools are concerned to handle all forensic process activities. Digital forensics is categorized into three types: The first is manual, meaning opening a personal computer, removing storage, and so on. Another method is to acquire a physical bit-by-bit image. The third method is logical data imaging, by extracting the logical structure of the disk.
Seamless Locomotion

In this chapter, we’ll look at an immersive movement mechanism that allows players to move smoothly in the VR world. If your game or experience is immersive, it’s more convincing if the illusion of immersion isn’t constantly being broken in the teleport movements. Seamless locomotion is also commonly referred to as slide movement and rotation. It’s worth noting that this form of locomotion isn’t for everyone. Players who are new to VR or just sensitive to it may not find this sliding movement and rotation comfortable, and it can cause nausea. Using seamless locomotion, the player can move around the virtual world by simply gliding along the floor surface, moving forward, back, or strafing left and right. The VRTK provides you with four ways to achieve this seamless locomotion, with each form involving a very subtle change. We’ll learn to implement all four forms of seamless locomotion provided in the VRTK.
Proximal policy optimization with adaptive threshold for symmetric relative density ratio

Deep reinforcement learning (DRL) is one of the promising approaches for introducing robots into complicated environments. The recent remarkable progress of DRL stands on regularization of policy, which allows the policy to improve stably and efficiently. A popular method, so-called proximal policy optimization (PPO), and its variants constrain density ratio of the latest and baseline policies when the density ratio exceeds a given threshold. This threshold can be designed relatively intuitively, and in fact its recommended value range has been suggested. However, the density ratio is asymmetric for its center, and the possible error scale from its center, which should be close to the threshold, would depend on how the baseline policy is given. In order to maximize the values of regularization of policy, this paper proposes a new PPO derived using relative Pearson (RPE) divergence, therefore so-called PPO-RPE, to design the threshold adaptively. In PPO-RPE, the relative density ratio, which can be formed with symmetry, replaces the raw density ratio. Thanks to this symmetry, its error scale from center can easily be estimated, hence, the threshold can be adapted for the estimated error scale. From three simple benchmark simulations, the importance of algorithm-dependent threshold design is revealed. By simulating additional four locomotion tasks, it is verified that the proposed method statistically contributes to task accomplishment by appropriately restricting the policy updates.
Authorization and Authentication in Mobile Devices

Abstract: With the rapid evolution of the wireless communication technology, user authorization and authentication is important in order to ensure the security of the wireless communication technology. Password play an important role in the process of authentication. In the process of authentication, the password enter by the user will be transmitted along the traffic to the authentication server in order to allow the server to grant access to the authorized user. The attackers will use the chance to attempt sniff others person password in order to perform some illegal activities by using others person password in order to perform some illegal activities by using others identitity to keep them safe from trouble. Due to the issues, there are many solutions has been proposed to improve the security of wireless communication technology. In this paper. The previously proposed solution will be used to enhance the security of the system. . For mobile apps , we need to make a clear distinction between user authentication and app authentication. User authentication is about how users prove that they are the legitimate apps users. App authentication covers how the app authenticates towards the backend . Sometimes device authentication also mentioned , is accessible to all apps running on your phone and generally easy to spoofs. Keywords: Authorization , Authentication , Cryptography , Hash Function , Face Authentication.

After the dissolution of the Dokdo Volunteer Guards, the members of the Dokdo protection activities

After Dokdo Volunteer Guards were disbanded, the members of Dokdo Volunte er Guards activities to protect Dokdo can be divided into two types. The first is Dokdo Security Police established by the Korean government to strengthen Dokdo sovereignty, laying the foundation for Dokdo security. The nine members were specially hired by Gyeongsangbuk-do Provincial Police and they has played a central role in the security of Dokdo while working as police officials. Their activities greatly contributed to the stable settlement of the Dokdo Security Police in Dokdo. The second is civilian activities targeting Dokdo. Activities centered on Hong Soon-chil can be divided into Dokdo Development, the establishment of a corporati on. Most of their civilian activities were not implemented because they were not approved by the government. But their proposed projects were implemented by the government and businesses in the 1990s and achieved great results. As such, it can be seen that even after the dissolution of Dokdo Volunteer Guards, the member s directly or indirectly contributed to Dokdo protection activities.

One and a half years ago, I wrote here about the worldwide race to contain the spread of COVID-19 with the help of smartphone contact tracing. While we are still very much living with the virus, most parts of the world seem to have silently given up on these apps. Have we overestimated the power of pervasive technology to solve real-world problems?

Facelets Templating

When Jakarta Faces came out for first time in 2004, only Jakarta Pages (formerly known as JSP) was available as view technology. It was immediately clear that it was an ill-suited view technology for web development with Jakarta Faces. The problem with Jakarta Pages is that it writes to the HTTP response as soon as it encounters template text, while Jakarta Faces would like to first create a component tree based on the view declaration in order to be able to perform the life cycle processing on it. For example, the following Jakarta Faces 1.0/1.1 page using Jakarta Pages view technology:

A proof system for graph (non)-isomorphism verification

In order to be able to apply graph canonical labelling and isomorphism checking within interactive theorem provers, either these checking algorithms must be mechanically verified, or their results must be verifiable by independent checkers. We analyze a state-of-the-art graph canonical labelling algorithm (described by McKay and Piperno) and formulate it in a form of a formal proof system. We provide an implementation that can export a proof that the obtained graph is the canonical form of a given graph. Such proofs are then verified by our independent checker, and can be used to certify that two given graphs are non-isomorphic.
Male and Female Students’ Abilities in Creating the Peaceable Classroom

This research aims to describe and compare male and female students' abilities in creating a peaceable classroom.A quantitative approach by selecting the descriptive and comparative design was employed to conduct this research.Twenty-four secondary students were involved in this research.A questionnaire consisting of thirty-six close questions regarding abilities to create a peaceable classroom was administrated to them.The questionnaire had been validated theoretically and empirically.To describe the level of male and female students' abilities in creating a peaceable classroom, a classification of scoring developed by Azwar was used, while the t-test was used to compare male and female students' abilities in creating a peaceable classroom.The results revealed that overall, male and female students had a moderate ability in creating a peaceable classroom.Also, there was no significant difference in abilities to create a peaceable classroom between male students and female students.However, descriptively, in creating the peaceable classroom, male students' abilities were higher than female students' abilities.It means that in appreciating the opinion of other students, not discriminating and cornering other students, saying kind words, talking softly and politely, and showing respect, male students' abilities were better than female students' abilities.
Research on Mobile-Assisted English Language Learning Among Primary School Students in China: Focusing on Students’ Feedback of Learning English with Mobile Devices

Guided by the conceptual framework of mobile-assisted language learning (MALL) in informal settings, this study investigates how primary school students in China use mobile devices to learn English out of class, focusing on students’ feedback of learning English through an app named “We Speak”.The data was collected through quantitative data of completed responses to a desgined online survey questionnaire and qualitative data from follow-up email interviews with parents and face-to-face interviews with teachers. This study demonstrates students’ positive and effective learning feedback by using this app to practice English and suggests an approch for English as a foreign language (EFL) learning with mobile devices[1]. The findings bear significant pedagogical implications for teachers to intergarte MALL into their teaching curriculum objective to achieve specific teaching tasks of mobile pedagogy and provide parents with hints on how to better schedule and support their children’s learning outside class.

Polydomous Ant Colony Optimization for Distributed Generation and Capacitors Placement in the Context of Techno-Economic and Environmental Objectives

This paper introduces a novel polydomous ant colony optimization technique (PACO) for DG and capacitor integration in distribution networks. The main focus is to propose the improvement to basic ant colony optimization and to implement this proposed method for DG and capacitor placements. The basic ACO is improved using the logarithmic eta function. The proposed method intends to provide technical, economic, and environmental advantages. Minimizing power losses, voltage variation, total cost, total emissions produced by generation sources, and raising the voltage stability index are among the objective functions examined. The effectiveness and the robustness of the suggested method is analyzed on two test systems. The case study's findings reveal that optimal DG location and sizing are essential for improving the voltage profile, reducing cost, and reducing emissions and losses in the distribution system. The algorithm's major characteristics are its accuracy and calculating speed.
