Search Results on Flight Booking Websites: Displaying Departure and Return Flights on a Single Page vs Two Consecutive Pages

Flight ticket booking engines on airline and online travel agency websites use two different designs to present roundtrip flight search results: some websites display outbound and return flights on a single page, while others show them on two consecutive pages. In our pilot experiment with 23 users we compared these two design options on a model flight booking website. Usability metrics like speed of performance and error rate were accompanied by eye-tracking and mouse-tracking indicators of cognitive load. The experiment produced mixed results: two-page design outperformed simultaneous presentation of outbound and inbound flights in terms of performance speed, but it also caused almost three times higher error rate and incurred a higher cognitive load compared to one-page design. Further research, with more users representing different age groups, different levels of task complexity, and analysis of users’ subjective preferences, is necessary.
Programming a D-wave annealing-based quantum computer: tools and techniques

Quantum annealing is a form of quantum computing that exploits quantum effects to probabilistically solve a specific, NP-hard problem: finding the ground state of a classical, Ising-model Hamiltonian. Because physical quantum annealers are already available, there exists the pressing question of how to program such systems. That is, how can one map a computational problem into the coefficients of an Ising-model Hamiltonian for solution by quantum-annealing hardware? In this article, we address that question primarily from a practical standpoint. We survey extant software tools intended for programming D-wave annealing-based quantum processors and examine the programming model and solution technique promoted by each tool in an attempt to showcase the variety of contemporary approaches to solving computationally challenging problems on an existing annealing-based quantum computer.

Reliability Studies of Different Readers Using Computer Aided Diagnosis System in Ultrasound for Determining Identical Lesions in a Breast Phantom

Background: The computer-aided diagnosis (CAD) has been applied in multiple studies conducted recently in order to perform ultrasound (US) of the breast. There are several studies that have indicated that CAD is useful for improving the diagnostic performance in less experienced radiologists. However, there is no study on several readers analyzing the same lesions using a breast phantom and rare reliability studies. Objectives: To investigate the reliability of different readers using computer aided diagnosis (CAD) system in US for determining identical lesions in a breast phantom. Patients and Methods: From March 2016 to February 2017, six readers (three senior and three junior residents in the department of radiology) evaluated and analyzed breast phantom including 14 lesions. At the first line study, three senior residents (3rd grade with more than one month of training for breast ultrasound [US]) and three junior residents (1st grade without breast US training) evaluated and analyzed the US and applied CAD for lesions in breast phantom, and they were able to make final decisions by subjective combination. A month later, they conducted the second line study as they did the first line study. We analyzed the inter- and intra-reader reliability and accuracy of US, CAD, and combinations (subjective, conjunctive, and disjunctive). Results: In the total of first and second line studies of six readers, the kappa value of US (0.609) was significantly higher than CAD (0.411). In the subjective combined conclusion, the kappa value was improved by the junior group. In the whole inter- and intra-reader analysis, the kappa values of final assessment of the senior and junior group were more variable on CAD than on US, especially in the junior group, and this result was statistically significant. The area under the curve (AUC) of US, CAD, subjective, conjunctive, and disjunctive combination in seniors were all better than those of juniors. In all groups, the AUCs, sensitivities, and specificities were improved on conjunctive combined US with CAD. Conclusion: The combination US with CAD improved the reliability and diagnostic performance. The CAD results of the junior group were variable and inconsistent. Therefore, minimum training and experience for breast US is indispensable for the better use of breast CAD, and, combination US with CAD is useful for all readers.
Patent Abstract Analysis on Chinese Big Data Based on A Filter-Refinement Scheme

Great attention has been paid to big data technologies by both industry and academia in recent years.Patent analysis is widely viewed as an important tool for tracking these technologies.However, there are some challenges when searching patents in practice, especially in the coverage of research results.Most patent analysis methods use keywords to search for information.However, big data techniques involve in many applications, and different patent applicants make various subjective decisions in the selection of keywords.Considering this problem, we proposed a new, more precise method for big data patent analysis based on a novel filter-refinement scheme.We compared our method with other keyword extracted methods, including SegPhrase, C-value, and Word2vec, etc.The experimental results show that the phrases extracted by the filter-refinement scheme outperformed the competitors on various measures and most of these phrases have a high quality.By applying our results to the analysis of domestic big data technologies in China, we found that there is greater development in industry than in academia; Huawei has the largest number of patent applications.In addition, the development of big data technologies in China is unbalanced, with the development level of the eastern regions significantly outperforming that of the western regions.Availability: The data sets and sample Python (Version 2.7.11) source code used in the paper are available on the following Baidu cloud network disk: https://pan.baidu.com/
Thin-Plate Spline-based Adaptive 3D Surround View

A “Bird's Eye View” (or Surround View) is a popular feature in modern cars and is particularly useful for parking and unparking purposes. This 3D reconstruction of the view uses multiple fisheye cameras and has traditionally been performed by a computer vision-based approach on a fixed mesh. This method is computationally expensive and does not always give ideal results for different types of surroundings. This paper discusses the design and implementation of a Thin-Plate Spline (TPS) algorithm for creating a 3D surround view of the vehicle with configurable vantage points and can be computed efficiently. Furthermore, it can choose from different meshes to adaptively generate a match with different surround-view environments on the fly. By surveying different environments and testing the implementation in a real car, we are able to demonstrate the practical feasibility of our solution 11The video demos of our algorithm have been uploaded to Youtube: https://www.youtube.com/watch?v=-boYsUSA52c, https://www.youtube.com/watch?v=NED435Uj12E. https://www.youtube.com/watch?v=2sZTCIi4X2M&t=2s. Our approach is competitive with the-state-of-the-art 3D reconstruction algorithms in computer vision while having a considerably lower runtime complexity.

Planning, Scheduling, and Deploying for Computational Ferrying

Mobile Cyber-Physical Systems are expected to perform resource intensive tasks that exceed their hardware (storage and computational power) capabilities. One traditional approach to solve this limitation is through cloud-based solutions. However, this approach may fail in scenarios with limited communication connectivity that can arise due to natural or adversarial conditions. One such scenario are battlefield tactical missions where soldiers may require access to large processing and storage capabilities for task such as tracking or battlefield awareness without sacrificing their mobility capabilities. In this paper, we extend previous work on computationalferrying, where Mobile High Performance Computers (MHPCs) can physically move the necessary hardware into the proximity of mobile units. Our extension proposes several improvements over the state of the art. First, we propose path planning algorithms to find reliable a priori estimation of distances between locations to obtain accurate scheduling. Second, we model MHPCs as autonomous vehicles which leads to more realistic scenarios in environment with obstacles. Third, we explicitly characterize the computational complexity of our proposed work. Finally, we implemented and tested in computer simulation all our algorithms to understand the effect of different obstacles, processors, number of MHPCs in completion time and deadlines meet.
AN ASSESSMENT ON EARLY WARNING SYSTEM: INITIAL SURVEY ANALYSIS

In Cameron Highland, Lembah Bertam area and further downstream villages in Susu Dam area are prone and vulnerable to the highest occurrence of floods especially during monsoon season. Thus, Early Warning System (EWS) were set up to avoid or to reduce the impact of natural hazard turns disasters such as floods, landslides and storms with the aim to reduce the vulnerability and disaster risks that signifies the effectiveness of EWS in the realisation of affected community. To test the awareness and preparedness of community in the selected area, a questionnaire survey was employed as the data collection method. The questionnaire survey was conducted before the direct engagement on the EWS information with the community. Using the mixed sampling method of cluster random sampling, a total of 800 respondents from 11 villages, and 5 main ethnicity groups were involved in the survey. From the result, there was a positive relationship showing that respondents who claimed they knew about the EWS from information signage were those from the older age category and earninghigher monthly income. On the other hand, there is a negative relationship between respondents’ age and monthly income against other sources that indicates respondents who claimed they knew about the EWS from other sources were those in the younger age category and have low monthly income.
Malleability and ownership of proxy signatures: Towards a stronger definition and its limitations

Proxy signature is a cryptographic primitive that allows an entity to delegate singing rights to another entity. Noticing the ad-hoc nature of security analysis prevalent in the existing literature, Boldyreva, Palacio and Warinschi proposed a formal security model for proxy signature. We revisit their proposed security definition in the context of the most natural construction of proxy signature – delegation-by-certificate. Our analysis indicates certain limitations of their definition that arise due to malleability of proxy signature as well as signature ownership in the context of standard signature. We propose a stronger definition of proxy signature to address these issues. However, we observe that the natural reductionist security argument of the delegation-by certificate proxy signature construction under this definition seems to require a rather unnatural security property for a standard signature.
PERAN DAN FUNGSI SELF-ACCESS LEARNING CENTER DI UNY

(Title: Role and Function of Self-Access Learning Center in UNY). This study aims to develop self-access reading materials for learning English independently. This research was conducted with the Research and Development model by following the steps: needs assessment, design and development, evaluation and revision, and a try out field. Data collected through questionnaires. There are three questionnaires used, namely for needs assessment, for expert judgment, and for field trials. Sample for needs assessment was taken by proportional quota sampling representing all faculties at UNY, while samples for the trial were taken purposively. The collected data was analyzed descriptively quantitatively. The results of the study showed that SAC UNY had not been widely known by students. Even after the introduction of online tutorials since 2015, the SAC is no longer visited by students. Thus the teaching materials developed should also be in the form of online. SAC socialization was also deemed necessary so that students were more familiar with the existence, function, and role of SAC in developing the English language skills of UNY students.Keyword: SAC, teaching materials, language skills, English
Subverting Democracy to Save Democracy: Canada’s Extra-Constitutional Approaches to Battling 'Fake News'

This paper considers Canada’s responses to the spread of online misinformation in an electoral context, particularly through updated criminal provisions prohibiting the spread of false information in the Canada Elections Act, and through a recent push to “jawbone” online platforms into taking proactive measures to stem the flow of problematic speech, arguing that both of these raise substantial freedom of expression concerns, and that efforts to sidestep key constitutional questions around the appropriate scope of restrictions on political speech may ultimately pose a greater threat to Canadian democracy than online misinformation.
Perception of the Mongolian People on the Korean Wave -Based on the Results of the Focus Group Discussion-

This paper mainly deals with the perception of the Mongolian people on the Korean wave. This paper discusses on major findings of the results of the focus group discussions(FGD) through their impressions on Korea, Koreans, Korean culture and Korean products(food, clothing, electronics, etc). In addition, this paper introduces the perception of the Mongolian respondents on such topics as follows: Korean entertainments(movie, drama and K-pop), the positive and negative effects of the Korean wave in Mongolia, and the implications of the Korean wave. This research uses Focus Group Discussion(FGD) method with exploratory and open-ended questions. The FGD was conducted for four groups, which were carried out in Ulaanbaatar, the capital city of Mongolia. As a result of the FGDs in Mongolia, K-wave effects are found to be mostly in positive ways. One of the notable implications is that Korea itself is a good example of development for Mongolia’s future. On the other hand, there are also some negative effects as well. It is thus necessary to have a more in-depth understanding and cooperation for the better mutual benefits for both Korea and Mongolia.

Self-regulation in Mathematics Courses for Engineering Based on Study and Research Paths

Several studies have shown that there is a positive correlation between self-regulation and the academic performance of students. Self-regulated learning is the set of processes that the learners deploy to achieve their personal goals and that have to do with the learning strategies they use, with the answers they offer when evaluating the effectiveness of learning and with the motivations they have. To this end, the Study and Research Paths (SRPs) strategy is proposed to encourage better self-regulation processes in the students of the Unidad Profesional Interdisciplinaria de Ingeniería Campus Guanajuato (UPIIG) of the Instituto Politécnico Nacional (IPN). This strategy was proposed by Yves Chevallard within the framework of the Anthropological Theory of the Didactic and the World Questioning Paradigm. Students of the courses of Numerical Methods and Numerical Analysis of the academic programs of engineering in: Aeronautics, Automotive Systems, Biotechnology and Pharmaceutical formed the study group. This research work presents the analysis of the results of the initial phase of the measurement of the evolution of the self-regulatory processes that students use in the development of engineering projects that need the application of numerical methods for the analysis of situations, the decision making and the development of new products.
Un modelo de aprendizaje estratégico para el aprendizaje de idiomas

The current study reports the findings emerging from the use of a modified instructional approach to learn another language based on learning strategies as originally devised by Chamot (2004) to provide pre-service teachers with basic communicative competences. The mother tongue is of vital importance when learning another language as there are transferrable strategies that can be used to support this process. The modified model employed both individual and group reflection to facilitate metacognition in a community of practice. The study followed a case study methodology within a mixed-methods approach including a questionnaire and reflective diaries written by 32 participants, five of whom were randomly chosen as the sample. The data interpretation was carried out according to the principles of phenomenology and consisted of percentages as well as frequency and thematic analyses, respectively. The findings showed that the modified language learning strategy model developed a greater use of direct and indirect strategies and contributed to generate, encourage and support the acquisition and basic communicative competences in another language.
