Formalization of Context-Free Language Theory

Proof assistants are software-based tools that are used in the mechanization of proof construction and validation in mathematics and computer science, and also in certified program development.Different such tools are being increasingly used in order to accelerate and simplify proof checking, and the Coq proof assistant is one of the most well known and used in large-scale projects.Language and automata theory is a well-established area of mathematics, relevant to computer science foundations and information technology.In particular, context-free language theory is of fundamental importance in the analysis, design, and implementation of computer programming languages.This work describes a formalization effort, using the Coq proof assistant, of fundamental results of the classical theory of contextfree grammars and languages.These include closure properties (union, concatenation, and Kleene star), grammar simplification (elimination of useless symbols, inaccessible symbols, empty rules, and unit rules), the existence of a Chomsky Normal Form for context-free grammars and the Pumping Lemma for context-free languages.The result is an important set of libraries covering the main results of context-free language theory, with more than 500 lemmas and theorems fully proved and checked.As it turns out, this is a comprehensive formalization of the classical context-free language theory in the Coq proof assistant and includes the formalization of the Pumping Lemma for context-free languages.The perspectives for the further development of this work are diverse and can be grouped in three different areas: inclusion of new devices and results, code extraction, and general enhancements of its libraries.
STABILITY-BASED LIVE MIGRATION USING DYNAMIC MARGIN

Virtualized environments are common in cloud services. In a virtualized environment, the efficiency of resources is improved by overcommitting. However, excessive overcommits may overload a virtual machine (VM) and subsequently affect other VMs.
Path Planning with Inventory-Driven Jump-Point-Search

In many navigational domains the traversability of cells is conditioned on the path taken. This is often the case in videogames, in which a character may need to acquire a certain object (i.e., a key or a flying suit) to be able to traverse specific locations (e.g., doors or high walls). In order for non-player characters to handle such scenarios we present InvJPS, an “inventory-driven” pathfinding approach based on the highly successful grid-based Jump-Point-Search (JPS) algorithm. We show, formally and experimentally, that the InvJPS preserves JPS’s optimality guarantees and its symmetry breaking advantages in inventory-based variants of game maps.
Overall Lessons and Data Sets

In this final chapter, we summarize some lessons learnt on development, validation, and updating of prediction models, based on the empirical experience from case studies as described in this book, and modeling experience in other medical prediction problems. We consider the essential elements to successful modeling: appropriate methods; sufficient sample sizeSample size; emphasis on validation; using, not ignoring, subject matter knowledge. We also reflect further on modern machine learningMachine learning techniques. Reporting guidelines and risk of bias tools are discussed. We end this chapter with a description of the case studies used throughout this book, where data sets are available through the book’s website ( www.clinicalpredictionmodels.org ).
The Visual Guidance Technology of Synchronizing Camera Animation and 360-degree CVR for Science Education

360-degree cinematic virtual reality(CVR) could bring users a full perspective experience, but high freedom will cause the loss of important information. To bring the user back to the narrative thread, researchers have made a variety of guided attempts, such as using note reminders, voice guidance, and so on. However, these methods are less efficient and less controllable for CVR for the purpose of science education. To solve this issue, the authors proposed visual guidance technology by synchronizing camera animation and 360-degree video in VR. When the user does not operate the mouse, the CVR viewing angle is controlled by the camera animation synchronously. This technology effectively transmits important information while allowing users to interact with the 360 video freely, thus improving the cognitive effect in science education.

Predictive Role Discovery of Research Teams Using Ordinal Factorization Machines

In this paper, we address the problem of research role discovery, especially for large research institutes where similar yet separated teams co-exist. The roles that researchers play in a research team, i.e., principal investigator, sub-investigator and research staff, typically exhibit an ordinal relationship. In order to better incorporate the ordinal relationship into a role discovery model, we approach research role discovery as an ordinal regression problem. In the proposed approach, we represent a research team as a heterogeneous teamwork network and propose OrdinalFM, short for Ordinal Factorization Machines, to learn the role prediction function. OrdinalFM extends the traditional Factorization Machines (FM) in an effort to handle the ordinal relationship among learning targets. Experiments with a real-world research team dataset verify the advantages of OrdinalFM over state-of-the-art ordinal regression methods.

From Server to the Cloud: Sharing Our Alma Experiences Post-Migration

The goal of our presentation is to share some of our knowledge and experiences learned from transitioning to a cloud based system. Our Alma Implementation Team has continued to meet weekly since migration in order to expand our understanding of Alma and improve configuration, and workflow for areas such as fulfillment, resource management, acquisition, and administration. Our presentation will focus on challenges and accomplishments post-migration, including areas such as user authentication, user permissions, work orders, printing, working with local and consortial e-resources, proxy configuration, addressing ongoing frequent updates to the functionality, and more. The University of California, Santa Barbara (USCB) Library went live with Alma on July 3rd, 2017. Our pre-migration process began with the formation of the Alma Implementation Team, which was given six months to work with our appointed Ex Libris project team following an outlined task list. Once we were live in Alma, our team members who had become Alma certified began learning more about areas we still needed to configure, things that worked differently in Alma compared to Aleph. Our priority for go-live was User Authentication and Fulfillment -- making certain our patrons could check out materials. This, we achieved. Our post-migration successes began with a rigorous review of our policies and procedures. This is an ongoing process and an ongoing learning process.
Sistem Informasi Prediksi Penilaian Kredit Perbankan Menggunakan Algoritma K-Nearest Neighbor Classification

The existence of banking institutions is very important for people's lives, especially used for raise funds in the form of deposits, demand deposits, savings and others. Besides that, it is an institution banks can also play a role as channeling funds in the form of credit to the public and business entities that need it. Problems in credit disbursement cause bad loans from customers, causing losses to the bank. Credit assessment is one of the important stages that must be carried out by the bank before credit is given to the credit applicant. The credit appraisal process belongs to a semi-structured problem that is quite complex, therefore it is necessary to develop a system to predict the feasibility of applying for credit. The system built in this study uses the K-Nearest Neighbor Classification algorithm by assessing prospective borrowers from the training data used. Based on the research that has been done, the K-Nearest Neighbor Classification algorithm can be modeled in a bank credit assessment. System testing results show accuracy of calculation accuracy of 81,82%.
Reconsideration of the Notion of Independent Work of Students in the Use of Technologies of Distance Education

Varieties of independent activity of students in the process of study are considered in the article. The main principles of distance education are highlighted, their importance for the organization of independent work of students in the conditions of use of technologies of distance education. The positive aspects of independent work of students are noted. The theoretical materials of modern literature which provide convincing facts that the process of independent work of students in the conditions of the use of technologies of distance education is modified is changed - attention of the student to active interaction with the teacher is considered. The article states that the main motivation in the student's activity should be not the requirements of the teacher, namely the search activity, which contains the ability to choose the necessary material, set goals, rational ways to solve it, apply the acquired knowledge to solve task, to process and interpret scientific information in accordance with the tasks set.

항만물류조직구성원들의 보안능력에 영향을 미치는 요인

Currently, despite having active movements related to port logistics security, there is lack of awareness, education, and security systems related to port technology. Before implementing port logistics security, a mutual authentication agreement should be reached through the establishment of an integrated network that can share port logistics security information in real time. In order to achieve port competitiveness and strengthen logistics service, establishment of national strategy for logistics security is necessary. However, there is an urgent need to raise the security consciousness among the port logistics organization members and enhance the information security ability which is a crucial feature of the port logistics organization. Therefore, the objective of this study is to analyze the factors affecting the information security capacity of port logistics organization members. Even though the analysis rejected the hypothesis that security regulations affect security awareness, the security activities and security awareness were significantly correlated. It also has a positive impact on the relationship between security norms and security abilities, and security awareness and security abilities.

Security Analysis of the Mexican Fiscal Digital Certificate System

In 2005 the Mexican National tributary system (SAT) started an ambitious public key infrastructure project with the aim of providing to each Mexican citizen a public/private key pair along with a digital certificate that was issued by SAT itself. As of March 2016, approximately a total of 17 million certificates have been issued. This e-government system permits Mexican citizens to exercise a series of digital on-line services such as: tax declaration, official receipt issuing/verification, contract signing, etc. In particular, all Mexican official invoices became digital by January 2016, efectively going paperless for this service. In this paper, we carefully analyze the Mexican PKI system showing that it has several weak points that can be attacked by malicious adversaries. We report experimental evidence showing that one can launch a simple dictionary attack on SAT’s password-based authentication system. We also argue that due to the fact that the hash function SHA-1 has been recently completely broken, an attacker can produce the same signature for two different documents that will verify correctly when using any old FIEL certificate that has the RSA- 1204/SHA-1 signature suite.
THE EFFECTIVENESS OF USING GRAPHIC ORGANIZER CONCEPT ON STUDENTS’ READING SKILL

The aim of this research is to determine the effect of the implementation of the Graphic Organizer Concept on students’ reading skills. The method used for this study is Quasi Experimental Design with Pre-Experimental design type one-group pretest-posttest design. The total subject of this study is 15 of Primary Education Department second semester students. The Data collection techniques were carried out by tests. Test the validity of using Product Moment test while the reliability test uses Alpha, the data analysis technique uses the Kolmogorov-smirnov test with the help of the SPSS for windows program to test normality, and the t-test to test the hypothesis. Based on the research, there is an influence on the application of the Graphic Organizer Concept model, this is evidenced by the normality test results of data analysis obtained by the pretest significance of 0.134 0.05 and the posttest significance of 0.118 0.05. In the hypothesis test used the t-test, the results of the analysis of the t-test obtained t count (27,730) t table (2,131). Because t count t table then Ho is rejected and H1 is accepted. It means that graphic organizer concept affects the ability to read. The conclusion of this study is that the Graphic Organizer Concept learning model influences reading skills.

3D Articulated Model Retrieval Using Depth Image Input

In this paper, a novel framework to retrieve 3D articulated models from a database based on one or few depth images is presented. Existing state-of-the-arts retrieval approaches usually constrain the view points of query images or assume that the target models are rigid-body. When they are applied to retrieving articulated models, the retrieved results are substantially influenced by the model postures. In our work, we extracts the limbs and torso regions from projections and analyzes the features of local regions. The use of both global and local features can alleviate the disturbance of model postures in model retrieval. Experiments show that the proposed method can efficiently retrieve relevant models within a second, and provides higher retrieval accuracy than those of compared methods for not only rigid body 3D models but also models with articulated limbs.
