A new perspective on the powers of two descent for discrete logarithms in finite fields

A new proof is given for the correctness of the powers of two descent method for computing discrete logarithms. The result is slightly stronger than the original work, but more importantly we provide a unified geometric argument, eliminating the need to analyse all possible subgroups of $\mathrm{PGL}_2(\mathbb F_q)$. Our approach sheds new light on the role of $\mathrm{PGL}_2$, in the hope to eventually lead to a complete proof that discrete logarithms can be computed in quasi-polynomial time in finite fields of fixed characteristic.

Analysis on the Effective Method of Urban Lightweight Flood Control and Water Blocking Design

The increase in extreme weather around the world has led to frequent urban waterlogging in recent years, and the problems caused by urban drainage have emerged endlessly. When extreme weather and the backwardness of urban facilities lead to waterlogging, the city's own protection capacity is relatively weak. When people's property and safety are threatened to a certain extent, the existing anti-waterlogging facilities are relatively backward, and related urban supporting facilities are upgraded accordingly. When people's property and safety are threatened to a certain extent, the existing anti-waterlogging facilities are relatively backward, and related urban supporting facilities are upgraded accordingly. This partition has a better storage effect and simple operation, in more and more frequent waterlogging in the rainy season to become a more effective means of urban flood control. The article introduces the product design ideas and practical methods in detail, and carries out targeted simulation experiments to verify the water blocking effect. When the existing building facilities cannot improve the water-proof capacity on a large scale in a timely manner, the water blocking partition can effectively solve the problem of urban waterlogging, and it is an economical and innovative design with significant effects.
Decoherence assisted spin squeezing generation in superposition of tripartite GHZ and W states

In the present paper, we study spin squeezing under decoherence in the superposition of tripartite maximally entangled GHZ and W states. Here we use amplitude damping, phase damping and depolarisation channel. We have investigated the dynamics of spin squeezing with the interplay of superposition and decoherence parameters with different directions of the mean spin vector. We have found the mixture of GHZ and W states is robust against spin squeezing generation for amplitude damping and phase damping channels for certain directions of the mean spin vector. However, the depolarisation channel performs well for spin squeezing generation and generates permanent spin squeezing in the superposition of GHZ and W states.
SpreadMeNot: A Provably Secure and Privacy-Preserving Contact Tracing Protocol

A plethora of contact tracing apps have been developed and deployed in several countries around the world in the battle against Covid-19. However, people are rightfully concerned about the security and privacy risks of such applications. To this end, the contribution of this work is twofold. First, we present an in-depth analysis of the security and privacy characteristics of the most prominent contact tracing protocols, under both passive and active adversaries. The results of our study indicate that all protocols are vulnerable to a variety of attacks, mainly due to the deterministic nature of the underlying cryptographic protocols. Our second contribution is the design and implementation of SpreadMeNot, a novel contact tracing protocol that can defend against most passive and active attacks, thus providing strong (provable) security and privacy guarantees that are necessary for such a sensitive application. Our detailed analysis, both formal and experimental, shows that SpreadMeNot satisfies security, privacy, and performance requirements, hence being an ideal candidate for building a contact tracing solution that can be adopted by the majority of the general public, as well as to serve as an open-source reference for further developments in the field.
Secured ICA Technique on Bimodal Biometric Images Using Private Watermarking with DCT

With the discovery of paperless expensive means of internet access, network communication via social media is on the rise, which often comprises threats and distortions. Un authenticates identification may sometimes lead to ambiguities in end-user identification and misunderstandings. Therefore, proper identification of a person is a must in network communication. Image private watermarking[7][9][19] is one solution when the owner of the digital images are identified properly by embedding additional information such as a private watermark in the digital images like fingerprint and retina imperceptibly concealed inside another image. On the other hand, communication also leads to a serious surge in decompress technique on the images. This work introduces three techniques: digital watermarking, steganography, ICA[4][5][6][20][22]. Using a private watermark using the visible [9][7] and non-blind[9][19][7] technique on the photo image. Then two original fingerprints and retina images to achieve stego analysis technique to convert as a stego image. Then the stego image concealed by a watermarked photo image. Then mixing the two techniques to achieve the ICA[20][22][4][5][6] (Independent Component Analysis) for protecting data transmission. To providing compression using the IDCT (Inverse Discrete Cosine Transform) technique with the key using AES[10][9][19] (Advanced Encryption Standard) 64-bit algorithm. Implementation and to determine the utilize the JAVA platform.

Oracle® VirtualBox is an open-source hosted hypervisor for virtualization, developed by the Oracle Corporation. For this paper, we have created three virtual machines (VMs), each with different operating systems, assigned specific IP addresses for each VM and the host operating system. We have looked into the reasons for the choice of the IP class and networking mode among the Bridged, NAT or Host-only choice, then compared the networking modes based on the access between the VM and Host, VM and VM, and VM and LAN or external link.
A Survey Paper on Effective Query Processing for Semantic Web Data using Hadoop Components

The combination of the two quick creating logical exploration regions Semantic Web and Web Mining is called Semantic Web Mining. The immense increment in the measure of Semantic Web information turned into an ideal objective for some specialists to apply Data-Mining methods on it. Semantic Web Data is an extra for the World-Wide Web, and the primary goal of this is to make the web information machine-comprehensible. Resource Description Framework (RDF) is one of the advancements used to encode and speak to the semantics information as metadata. It's most likely to host the semantic web data on cloud due to its vast requirement, and also it can be managed well in terms of storage and evaluation. Map-reduce is a programming model that is well known for its scalability, flexibility, parallel processing, and cost-effective solution. Hadoop and Spark are the popular open-source tools for handling (Map-Reduce) and storing (HDFS) a huge-amount of data. Semantic web data can be processed using the SPARQL, which is a primary query language for processing the RDF. In terms of performance, SPARQL has a significant drawback comparing to Map-reduce. For Querying the RDF data, we use Spark and Hadoop components (PIG and HIVE). Where Considering Directed Acyclic Graph (DAG) scheduler as a specific feature for In-memory processing in spark. In this paper, evaluate and analyse performance results using RDF data, which contains 5000 triples by executing the benchmark queries in PIG, HIVE, and SPARK. A scalable and faster framework can be obtained based on practical evaluation and analysis.

Order-Aware Embedding Non-sampling Factorization Machines for Context-Aware Recommendation

FM can use the second-order feature interactions. Some researchers combine FM with deep learning to get the high-order interactions. However, these models rely on negative sampling. ENSFM adopts non-sampling and gets fine results, but it does not consider the high-order interactions. In this paper, we add the high-order interactions to ENSFM. We also introduce a technique called Order-aware Embedding. The excellent results show the effectiveness of our model.

STUDENT AND LECTURER RESPONSE ON THE IMPLEMENTATION OF LINE LEARNING

The purpose of this study was to describe the responses of students and lecturers to the implementation of online learning. The research data is in the form of the results of filling out a questionnaire containing closed questions and open questions related to the implementation of online learning. Data were collected by distributing questionnaires to 512 student respondents and 15 lecturer respondents. The results showed that both lecturers and students were not very happy with online learning. As for online learning that students prefer is synchronous online learning because students find it easier to understand learning material. Lecturers also prefer synchronous online learning because it is more flexible and can reduce the burden on lecturers. Even though online learning has been carried out, there are many obstacles faced by students and lecturers in implementing online learning. These constraints cause online learning to not be able to run effectively and fun, even it seems boring for students. Therefore, it can be suggested that learning can be carried out in a blended manner to minimize the obstacles faced.
Counterfactual Augmentation for Training Next Response Selection

This paper studies label augmentation for training dialogue response selection. The existing model is trained by “observational” annotation, where one observed response is annotated as gold. In this paper, we propose “counterfactual augmentation” of pseudo-positive labels. We validate that the effectiveness of augmented labels are comparable to positives, such that ours outperform state-of-the-arts without augmentation.

Intelligent Imaging Technology Implementation as Terrorism Prevention in Retail Sectors in 21st Century

Terrorism is a very dangerous thing and has become a threat both on a national and international scale. Understanding terrorism seeks to instill the seeds of hostility towards a group, government agencies and even the state. Before entering the 21st century terror attacks are blatant in the business sector by sabotaging and damaging public facilities and vital objects. These physical attacks can be prevented by recording personal identities or conducting regular security patrols and placing a large number of security personnel in places of business and places that are considered strategic. However, this is still not optimal where the level of security and the number of personnel are limited in monitoring the place for a long time and are sustainable. The terrorist attacks in the 21st century are different and require different handling. Attacks can be physical or non-physical. On non-physical objects attacks are usually carried out by hacking networks that can damage internet network connections in one area and even one country. Ways to prevent attacks that are physical in nature by utilizing computer vision technology capabilities that are used to record all civil society. An additional feature in this technology lies in the face recognition and pattern matching techniques where a person's face will be searched for unique features. Then from these data will be biometric data, namely data that will not change and disappear. Computer vision algorithms can detect a person's face or object even though it has been modified or changed in physical and color conditions. The advantages of these algorithms are effectively used to record visitor identities and are optimal in recognizing an object with an accuracy of up to 90%. This system is able to help and improve a security feature of a business and tourist area.

Multiple Objects Tracking with High-speed Multi-camera System

Multiple objects tracking is one of the most popular and important areas in computer vision. There are many applications of multiple objects tracking, for example inspection, surveillance, security, robot, factory automation, and so on. Especially multiple objects tracking of inspection has difficulty in distinguishing the target from the other ones with similar appearance. In this paper, I have proposed the method of multiple objects tracking with high-speed multi-camera system, which utilizes three-dimensional information about each target. This method has very simple algorithm because high framerate video makes the difference small between consecutive frames. In the future work, I will optimize the entire system from image acquisition, target detection to targets association, and develop this system so that it can be used in more complicated situations.

Clarifying the difference in consciousness about robots between home-economics and robotics students through a lecture

To resolve the lack of labor caused by the aging population, the social progress of working robots is expected. To realize their social progress, we should analyze and remove the elements of making consumers avoid their social progress. In this paper, we attempt to clarify the differences in consciousness about robots caused by the different backgrounds of home-economics, science, and robotics students, through a lecture and group discussion. From the result, we found that 1) home-economics students tended to have negative emotions such as fear and anxiousness about robots and 2) the lecture was useful for mitigating such negative emotions.
TYPES OF LEADERS: COPING STRATEGIES AND SOCIO-PSYCHOLOGICAL CHARACTERISTICS

The theoretical and empirical analysis of the concepts of coping strategy, locus of control (internality-externality) and achievement motivation is provided in the article. Various points of view on coping strategies, as well as on achievement motivation, social intelligence and internality as professionally important personality characteristics of leaders of the real sector of the economy are considered. The structure of the relationship of socio-psychological characteristics and coping strategies of leaders is revealed. The correlation of coping strategies and locus of control, achievement motivation is investigated. The results of the study of the relationship of coping strategies, locus of control, achievement motivation and socio-psychological characteristics among managers allowed us to draw the following conclusions. 1. Two types of leaders were obtained: “Internal” and “External”. 2. Each type of leader has his own combination of coping strategies. 3. Within each of the two types of leaders, subtypes are distinguished. As a result, we get a two-level typology, the second level of which includes five types of leaders, depending on their socio-psychological characteristics and preferred coping strategies. 4. All types are characterized only by their inherent features of coping behavior. The greatest differences in usage patterns were found in strategies such as Confrontational Coping, Positive Reappraisal, Self-Control, Distance, and Emotional Coping. All types of executives have the greatest preference for strategies such as Problem Coping and Problem Solving Planning. 5. The greatest contribution to the psychological characteristics of types was made by such qualities as aggressiveness, friendliness, dominance, altruism and authoritarianism. In addition, the level of internality (including general and relative to one’s own failures and achievements), personality traits (courage, suspicion, high normative behavior, dominance).

US Supreme Court holds that US state codes and annotations thereto are not eligible for copyright protection

Georgia v Public.Resource.Org, Inc, 140 S Ct 1498 (US 27 April 2020) On 27 April 2020, the US Supreme Court extended the government edicts doctrine, which holds that works authored by judges in the course of their official duties are in the public domain, to similar works created by the legislatures of US states, territories and the District of Columbia. The decision clarifies that this doctrine applies even to annotated versions of legal codes, to prevent a situation where there is ‘first class’ versus ‘economy class’ access to the law. That said, this decision will not stop states and territories from charging for access to such materials. However, those states and territories will no longer be able to prevent third parties from providing free access to such materials by invoking copyright restrictions. It has long been clear under US law that the text of legal codes is not...
Multivariate Analysis of Sensor Data NSARD Poster

objectives to the Principal Investigators meeting: (1) to provide opportunities to share research results and promote interactions among the SBR scientists and other invited guests; (2) to evaluate the progress of each project within the program; and (3) to showcase the scientific expertise and research progress over the past year to senior managers within the DOE Office of Science, the technology offices within DOE, and other invited attendees from other Federal Agencies. This past year has seen a few significant changes within BER and within the SBR program. In November, our Associate Director for BER, Anna Palmisano, retired from Federal service. Just this month, Dr. Sharlene Weatherwax (Division Director for Biological Systems Sciences) has been named as the new Associate Director for BER. In August, BER welcomed Dr. Gary Geernaert as the new Division Director for CESD. Gary joins the division from Los Alamos National Laboratory with a background in atmospheric science. Within the SBR program, a new Strategic Plan was completed last June (currently posted on the SBR and the Office of Science website). The new strategic plan is intended to foster integration within the Environmental Systems Science portion of the BER budget that includes both SBR and Terrestrial Ecosystem Sciences (TES). Both these programs share a goal of advancing a predictive understanding of environmental processes and utilizing iterative, multidisciplinary approaches to understand complex environmental systems of relevance to DOE. CESD in general is undergoing continued discussions on integration among its programs in an effort to develop a new strategic plan for the division. This effort also includes identifying opportunities for integration with BER's Biological Systems Science Division (BSSD). The program this year includes three poster presentation sessions, six plenary sessions, and three breakout sessions. The plenary session on Tuesday morning will feature introductory presentations by BER program staff and three keynote addresses from Dr. Ken Bencala (USGS), Dr. Michael (Mick) Follows (MIT) and Dr. Sue Brantley (PSU) that will lead into three breakout sessions Tuesday afternoon. The breakout sessions are intended to highlight key developments in SBR research and foster a dialog among session participants on scientific paths forward in each particular area. The SBR program managers are asking for input from the SBR community at these sessions to help guide future efforts and/or identify areas of integration within BER programs. On Wednesday, plenary sessions will continue in the morning, followed by an early afternoon poster session. After an extended break for lunch, plenary sessions will continue in the afternoon, followed by an evening poster session. Thursday's plenary session will focus on selected highlights of research efforts at the IFRC sites and on a new potential TES field effort in the Arctic. This new field site is an obvious point of integration between the SBR and TES programs.
