Analysis of radar images of the Sentinel-1 satellite using the EO Browser web resource

The article's purpose is to review the capabilities of the EO Browser web resource and tools for remote sensing data analysis and visualization. Examples of satellite images obtained using a synthetic aperture radar are given. The presented results were obtained during the processing of radar images of the Sentinel-1 satellite, which are freely available thanks to the implementation of the Copernicus program concept regarding the public availability of Earth remote sensing data. The results of satellite radar acquisition are used to prevent, preserve, and forecast natural or technogenic threats and risks, considering the high frequency of acquisition and the promptness of obtained data. The effectiveness of using the web resource in solving the environmental monitoring tasks in seawater areas, identifying accident sites, determining the area of oil spills, planning measures to eliminate the consequences and reduce environmental risks, and collecting the evidence base about the event is shown. The mechanism of reflection of the radar signal from various natural surfaces (including oil spills into the sea) and artificial objects (for detecting the position of sea vessels) is considered. A comparison of the effectiveness of using radar images of the Sentinel-1 satellite with optical images taken by the Sentinel-2 satellite for monitoring the condition of forest areas was performed. Satellite radar images are a reliable data source for continuously monitoring unregulated woodland destruction. The results' practical significance lies in using EO Browser to solve a wide range of scientific, practical, and educational problems using radar images. Further research using satellite radar images and the EO Browser platform is related to environmental monitoring in marine water areas. This applies to issues related to the detection of accumulations of garbage and plastic on water surfaces. It is promising to use the potential of the web resource for position designing and rapid determination of the effectiveness of deploying ground corner reflectors during geodynamic monitoring of the earth's surface.

Making contract users safer: Towards building a Safe Browsing platform on Ethereum

There are many papers and tools regarding the detection of unsafe contracts, but few ways for detection results to practically benefit contract users and owners. This paper presents a Blockchain Safe Browsing (BSB) platform to safely disseminate those detection results. An encrypted blacklist will be generated to provide privacy preserving user warning before they make transactions with unsafe contracts. Contract owners will be notified that there are vulnerabilities in their contracts, and they can purchase related reports which record how to exploit the vulnerabilities. The profits inspire the researchers to contribute their update-to-date lists of unsafe contracts. An effective encryption scheme is developed to guarantee that only contract owners can decrypt the encrypted reports. Extensive evaluations demonstrate that our prototype can function as intended without sacrificing user experience.

Architectural Generativity: Leveraging Complementor Contributions to the Platform Architecture

In the context of platforms, an open architecture is instrumental in enabling innovation by complementors. But as complementors increasingly deplete the innovation opportunities that the platform architecture affords, the platform architecture must evolve to reinvigorate the platform’s generative capacity. This article underscores the role of complementors in the process of platform architecture evolution by introducing the notion of architectural generativity. Architectural generativity involves actively soliciting and selectively incorporating contributions from complementors to help evolve the platform in unforeseen ways. In the case of the Mozilla Firefox web browser platform, complementors contributed new ways to facilitate access to the platform’s technological components and suggested better ways to control the platform and its architecture.

Identification of Biomarkers Related to the Efficacy of Radiotherapy in Pancreatic Cancer.

Pancreatic cancer (PC) has one of the highest mortality rates, with an overall five-year survival rate of only 7%. When diagnosed, PC is limited to the pancreas in only 20% of patients, whereas in 50% it has already metastasized. This is due to its late diagnosis, which makes the treatments used, such as radiotherapy, difficult, and reduces survival rates. Therefore, the importance of this study in detecting genes that may become possible biomarkers for this type of tumor, especially regarding the human secretome, is highlighted. These genes participate in pathways that are responsible for tumor migration and resistance to therapies, along with other important factors. To achieve these goals, the following online tools and platforms have been expanded to discover and validate these biomarkers: The Human Protein Atlas database, the Xena Browser platform, Gene Expression Omnibus, the EnrichR platform and the Kaplan-Meier Plotter platform. Our study adopted a methodology that allows the identification of potential biomarkers related to the effectiveness of radiotherapy in PC. Inflammatory pathways were predominantly enriched, related to the regulation of biological processes, primarily in cytokine-derived proteins, which are responsible for tumor progression and other processes that contribute to the development of the disease. Radiotherapy treatment demonstrated greater efficacy when used in conjunction with other forms of therapy since it decreased the expression of essential genes involved in several inflammatory pathways linked to tumor progression.

A Location Management Strategy for Satellite Internet Constellation

Satellites are currently the most effective means to achieve seamless global coverage of the Internet. Due to the frequent beam switching caused by the high-speed movement of satellites, it is too expensive to directly apply the location management strategy in the terrestrial network to the satellite Internet constellation (SIC). To build a web browsing platform based on satellite Internet, it is necessary to display the location of satellites and terminals in real time. For this reason, this paper proposes the location management strategy of SIC. It uses the characteristics of large and periodic satellite beam coverage in a certain period of time, redesigns the location management database structure, location registration mechanism and call delivery mechanism, and analyses and simulates the bit cost of location management. The result proves that compared with the traditional strategy, this strategy greatly reduces the cost of SIC.

ACTIVIST BROWSER EXTENSIONS AS INTERFACE DÉTOURNEMENT: REMINDING, COPING, AND INFRASTRUCTURAL ALIGNMENT

This paper investigates web browser extensions as an under-researched media object for their capacity for activism. “Activist extensions” disrupt a webpage’s intended use and redirect users’ attention to social issues by modifying textual, visual, or auditory elements of the web user interface. The relevance of the study stems from the ubiquity of the web browser as a communication tool and the potential of browser extensions to counter its power in shaping how web content is delivered to users. Based on the notions of transduction and affordance, the critical vocabulary of the Situationist International, and the conceptualization of platform governance through the provision of infrastructural services, this paper asks: Through what mechanism do activist extensions redirect users’ attention to social issues? What are the potential implications for users? And, how can browser platforms affect the creation and distribution of activist extensions? The study adopts a mixed-methods approach that includes discursive interface analysis of the extensions’ modification of the browser interface, critical discourse analysis of user comments on these extensions, and semi-structured interviews with extension developers. Major findings of the study include: 1) the redirection of users’ attention from the webpage to social issues is achieved through the mechanism of $2 , 2) activist extensions function as $2 that provides users with a coping mechanism against certain online rhetoric, and 3) the creation and distribution of activist extensions are conditioned by an $2 imposed by the browser platform on extension developers.

Implications of Application Programming Interfaces for Third‐Party New App Development and Copycatting

Digital platforms can use application programming interfaces (APIs) to support third‐party development of new apps and achieve growth at an unprecedented scale. However, there is also a dilemma between original new development and copycatting by third‐party suppliers. Motivated by this tension, we examined how APIs provided by digital platforms may influence two types of third‐party new app development: original apps and app copycatting. We also investigated how these influences are dependent on app market conditions. We empirically tested our theoretical conjectures using data on a leading web browser platform, and applying analytics techniques on app source code to identify original apps and copycat apps. Based on a difference‐in‐differences identification strategy, our findings suggest that the provision of platform APIs enhance the original new development of apps. While platform APIs may facilitate app copycatting as well, our findings suggest that platform APIs can enhance app suppliers’ relative attractiveness to original new development in comparison to copycatting. The enhancing effect of platform APIs on original new development is strengthened by app market potential and high market‐level app complexity. The enhancing effect of platform APIs on app copycatting is strengthened by app market potential and high market concentration. Our study has important theoretical and practical implications.

Survival of the fittest: understanding the effectiveness of update speed in the ecosystem of software platforms

ABSTRACTThe ecosystem of software platforms is emerging as a dominant model for software-based services. Following the trend of open innovation, platforms extend product boundaries by encouraging many complementary apps to join them and organize an innovation ecosystem to satisfy the needs of heterogeneous users. In such innovation ecosystems, apps update and evolve continuously. Considering the ubiquitous nature of software updates, scholars have examined the impact of updates on the diffusion and market performance of focal software. However, few studies examined the moderators for the effectiveness of update speed. Apps, like organisms, do not exist in a vacuum. The success of one app depends not just on its own efforts but also on its interaction with other innovations in the ecosystem. Informed by the ecology theories, this study theorizes how the effectiveness of app update speed is influenced by ecological factors. Using longitudinal data about apps in a browser platform, we obtain several important insights. First, update speed has a significant positive effect on app performance. Second, frequent platform update and intraspecific competition weaken the effectiveness of update speed. Third, interspecific mutualism and developer capability strengthen the effectiveness of update speed. This study contributes by advancing the overall understanding of value software updates as well as providing novel insights about the interdependence in innovation ecosystems.

A Comparison of Mobile Banking Service Quality between APP and Web Browser

This study aimed to explore the customer demands for service quality on both the application (APP) platform and web browser platform, and compare the differences of service demands among customers of different ages regarding the APP platform and web browser platform. A questionnaire survey was conducted on banking customers of the APP platform and web browser platform in Taiwan. This study utilised the moderated regression model to classify Kano two-dimensional quality. The findings showed that the Kano two-dimensional quality of mobile banking service was quite different between the APP platform and the web browser platform. The service demands among customers of different ages were also quite different regarding the APP and web browser platforms. These results suggested that the management strategies of mobile banking should be put forward according to customer demands for service quality on the different platforms.

Virtual Serendipity: Preserving Embodied Browsing Activity in the 21st Century Research Library

As academic library collections are moved off site to make room for learning commons-type collaboration spaces, exploratory research processes (e.g. stacks browsing activities) are threatened. Given the range of benefits associated with chance information encounters in the physical book stacks, the disappearance of accessible collections is problematic. Fortunately, by focusing on embodied aspects of the physical browsing experience we can leverage emerging technologies to preserve instances of serendipitous information retrieval. Virtual reality, in this case, provides a browsing platform that allows for the type of search activity typically associated with research in the physical books stacks and preserves the benefits thereof.

Fast algorithms for online construction of web tag clouds

In this paper tag cloud construction for web exposition is studied. Construction of a tag cloud must simultaneously solve at least three interdisciplinary engineering problems: modeling and controlling graphics aesthetics, solving discrete two-dimensional layout optimization problem, and all these must be done on computationally constrained browser platform. We analyze the design choices in the earlier tag cloud studies and provide a taxonomy of algorithmic approaches to tag cloud building. Then, the design requirements for tag clouds on websites are defined. We propose to quantify tag cloud aesthetics by use of a novel objective function based on the rules of typography. Tag cloud construction is formalized as a combinatorial optimization problem with an irregular objective function. A set of algorithms is proposed and evaluated on a collection of tag sets from popular web pages. The methods that meet constraints of the browser platform are chosen.

The Dark Side of User Participation - The Effect of Calls to Action on Trust and Information Revelation

Many content websites seek to encourage user participation, which has been shown to increase user satisfaction and propensity to contribute. Yet this study shows that such encouragement can cause users to expose themselves to potentially harmful consequences, by enhancing their trust in the website and leading them to be more willing to reveal personal information. We perform a series of empirical experiments, utilizing a website called VideoBook, a YouTube-like video browsing platform that provides the opportunity to study users’ behaviors and perceptions in a realistic environment and under lab conditions. We find that users who are exposed to prompts that require them to engage with the website (rate videos) subsequently report higher trust in the site and reveal more personal information, compared with users who are not exposed to such prompts. Exposure to prompts does not affect users’ general attitudes regarding privacy. We test alternative scenarios to attempt to identify the sources of the phenomena, and we link our results to previous work on website-initiated participation and self-perception theory. We discuss both theoretical and policy implications.

BIM을 이용한 정보 시각화에 관한 연구

The global warming has been recognized as a serious problem. To solve this problem, the country of all the world have conducted techniques such as energy saving and reduction of greenhouse gas. The 30% of total energy is being consumed by buildings domestically and BAS/BEMS are being operated for the management of building energy. But, BEMS is unsatisfactory condition to manage the energy efficiently. In this study, We investigate real application on Chamsaem elementary school as a target buildings and develop 3D Web Browser platform. The spatial information of target buildings is described with used BIM and the energy information is presented for facilities operation and electricity consumption in floor and facility. We perform the quantitative evaluation based on ISO/IEC 9126 and operate this system for two months. in result, energy decreased by about 16%. We expect that the proposed 3D Web Browser system will bring operating efficiency improvement of the current BEMS.

Video genre categorization and representation using audio-visual information

We propose an audio-visual approach to video genre classification using content descriptors that exploit audio, color, temporal, and contour information. Audio information is extracted at block-level, which has the advantage of capturing local temporal information. At the temporal structure level, we consider action content in relation to human perception. Color perception is quantified using statistics of color distribution, elementary hues, color properties, and relationships between colors. Further, we compute statistics of contour geometry and relationships. The main contribution of our work lies in harnessing the descriptive power of the combination of these descriptors in genre classification. Validation was carried out on over 91 h of video footage encompassing 7 common video genres, yielding average precision and recall ratios of 87% to 100% and 77% to 100%, respectively, and an overall average correct classification of up to 97%. Also, experimental comparison as part of the MediaEval 2011 benchmarking campaign demonstrated the efficiency of the proposed audio-visual descriptors over other existing approaches. Finally, we discuss a 3-D video browsing platform that displays movies using feature-based coordinates and thus regroups them according to genre.

Using Linked Data to Annotate and Search Educational Video Resources for Supporting Distance Learning

Multimedia educational resources play an important role in education, particularly for distance learning environments. With the rapid growth of the multimedia web, large numbers of educational video resources are increasingly being created by several different organizations. It is crucial to explore, share, reuse, and link these educational resources for better e-learning experiences. Most of the video resources are currently annotated in an isolated way, which means that they lack semantic connections. Thus, providing the facilities for annotating these video resources is highly demanded. These facilities create the semantic connections among video resources and allow their metadata to be understood globally. Adopting Linked Data technology, this paper introduces a video annotation and browser platform with two online tools: Annomation and SugarTube. Annomation enables users to semantically annotate video resources using vocabularies defined in the Linked Data cloud. SugarTube allows users to browse semantically linked educational video resources with enhanced web information from different online resources. In the prototype development, the platform uses existing video resources for the history courses from the Open University (United Kingdom). The result of the initial development demonstrates the benefits of applying Linked Data technology in the aspects of reusability, scalability, and extensibility.
