Cummings, Merrill, and Borrelli’s Inquiry into Small Screen Use by Academic Library Users: Timing is Everything

Objective – The authors undertook this study to understand the relatively new phenomenon of handheld computing and the use of small-screen devices among academic library users. They sought to determine if users would be inclined to search the online library catalogue on their devices and, by extension, if there would be a growing demand for small-screen compatible library services. Design – Online and paper surveys were used with both closed and open questions. Respondents included students, faculty, and staff at Washington State University (WSU). Setting – Washington State University Library, Pullman, Washington, United States of America. Subjects – The survey was open to any user of the Washington State University (Pullman) Library. The 206 respondents included 126 (61.2%) undergraduates, 26 (12.6%) graduate or professional students, 32 (15.3%) WSU employees, and 15 (7.3%) faculty members. Methods – A survey was distributed both online and on paper. The online version used Surveymonkey.com and participation was solicited through various social media. It was open for three months during the Spring semester, 2007. The paper version was distributed to all library users on two days in June 2007. Eighty-four online and 122 paper responses were received. Main Results – Most of the respondents (58.4%) who owned a personal digital assistant (PDA) or Web-enabled cell phone (WECP) indicated that they would search the library catalogue on a small-screen device. Responses to the open question “How would you use the OPAC [online public access catalogue] if it was available on a PDA or WECP?” were mixed, both positive and negative. The positive responders noted the possible time savings associated with the availability of more information on their devices. The negative responders noted the cost of data, the annoyance of public phone use, and the complex format of the current catalogue that would not transfer to a small screen. Conclusion – The authors cited the growing usage trends in handheld devices, along with the willingness of current owners to use their devices, to predict an increase in usage of small screen searching. They speculated that further research should investigate how small screens would be used and what would that experience look like, rather than if patrons would use them

VSLAM and Navigation System of Unmanned Ground Vehicle Based on RGB-D Camera

In this thesis, ROS (Robot Operating System) is used as the software platform and a simple unmanned ground vehicle that is designed and constructed by myself is used as the hardware platform. The most critical issues in the navigation technology of unmanned ground vehicles in unknown environments -SLAM (Simultaneous Localization and Mapping) and autonomous navigation technology are studied. Through the analysis of the principle and structure of visual SLAM, a visual simultaneous localization and mapping algorithm is build. Moreover, accelerate the visual SLAM algorithm through hardware replacement and software algorithm optimization. RealSense D435 is used as the camera of the VSLAM sensor. The algorithm extracts the features from the data of depth camera and calculates the odometry information of the unmanned vehicle through the features matching of the adjacent image. Then update the vehicle’s location and map data using the odometry information. Under the condition that the visual SLAM algorithm works normally, this thesis also uses the 3D map generated to derive the real-time 2D projection map. So as to apply it to the navigation algorithm. Then this thesis realize autonomous navigation and avoids the obstacle function of unmanned vehicle by controlling the driving speed and direction of the vehicle through the navigation algorithm using the 2D projection map. Unmanned ground vehicle path planning is mainly two parts: local path planning and global path planning. Global path planning is mainly used to plan the optimal path to the destination. Local path planning is mainly used to control the speed and direction of the UGV. This thesis analyzes and compares Dijkstra’s algorithm and A* algorithm. Considering the compatible to ROS, Dijkstra’s algorithm is finally used as the global path-planning algorithm. DWA (Dynamic Window Approach) algorithm is used as Local path planning. Under the control of the Dijkstra’s algorithm and the DWA algorithm, unmanned ground vehicles can automatically plan the optimal path to the target point and avoid obstacles. This thesis also designed and constructed a simple unmanned ground vehicle as an experimental platform and design a simple control method basing on differential wheeled unmanned ground vehicle and finally realized the autonomous navigation of unmanned ground vehicles and the function of avoiding obstacles through visual SLAM algorithm and autonomous navigation algorithm. Finally, the main work and deficiencies of this thesis are summarized. And the prospects and difficulties of the research field of unmanned ground vehicles are presented

Robot Vision for Manipulation: A Trip to Real-World Applications

Along the last decades, Robotics research has taken a major turn from laboratories to factories and ordinary real-world environments. Consequently, new issues to be overcome have arisen, specially when autonomous, dexterous robots are in place. In this paper, we present this evolution in the case of robot vision for manipulation through several robot developments, by analysing their challenges and proposed solutions. This overview highlights the need of using different techniques depending on the task at hand and the scenario to work in.This work was supported in part by the Ministerio de Economía y Competitividad under Grant DPI2015-69041-R, in part by Universitat Jaume I under Grant UJI-B2018-74, and in part by Generalitat Valenciana under Grant PROMETEO/2020/034 and GV/2020/051

Understanding the Impact of e-Filing System Performance on Tax Compliance Using the DeLone and McLean Model

This study aims to investigate the impact of e-filing system performance on tax compliance applying DeLone and McLean IS Success Model. The study samples are 128 Indonesian micro, small, and medium entrepreneur (MSME) that selected using proportional random sampling. Data was collected using questionnaires and analyzed using SEM-PLS. The results showed that information quality and service quality have a positive effect on system use. In addition, information quality and system quality positively affect user satisfaction. By contrast, there is no impact of trust in e-government to either system use and user satisfaction. System use and user satisfaction positively influence taxpayers’ compliance. Meanwhile, gender does not moderate the effect of system use and user satisfaction on tax compliance

Boosting E-Service Quality through IT Service Management of Online Stores

The intention of conducting such the research was to evaluate mediating roles of IT service management on information system success model and IT governance, further boosting E-service quality. A method combining convergent triangulation and an explanatory, follow-up design was implemented. The population engaged middle-up online stores that have marketed products online in five-year time in West Kalimantan. Questionnaires were completed by 99 out of 112 managers. Quantitative analysis was performed through SEMPLS. In-depth interviews and FGDs with 5 key informants, however, yielded data used for qualitative analysis. Results conclusively reveal that information system success model is insignificant for E-service quality despite direct, positive influences gained. In other words, the business success of online stores has no reliance on this type of model. The focus should be on IT governance reinforcing IT service management. The fact is supported by qualitative findings emphasizing that such the governance is eminently influenced by information system success model and it is requisite to actualize IT service management for progressed E-service quality

Nias-mukalla web based systems success measurement and students satisfaction evaluation based on security factor of systems quality engineering theory (ISO 25010) and other factors

Latest studies reported that systems success measure suffers from mix of results and limited models that help in success measurement and evaluation. Because of systems models are domain specific and context related, there is a dire need for taking the measure to other perspectives like using related external factors such as management support or using software engineering theories such as ISO 25010. This study aimed to move the measure from a business perspective to other perspectives. This study investigated NIAS-Mukalla student satisfaction based on security, management support, computer anxiety and usefulness. All these independent variables found to be positively and significantly affected the satisfaction of the users. NIAS-Mukalla students were satisfied with the web-based systems

Pursuing Digital Learning Platform Success: A Meta-Analytic Investigation of User and Cultural Contingencies

Digital learning platforms (DLPs) have emerged as highly effective tools to meet contemporary organizations’ learning and knowledge-creation needs. Advanced information and communication technologies (ICT) embedded in these platforms create mobile learning workspaces that deliver ubiquitous yet targeted learning experiences. Scholars have shown a keen interest in assessing the success of DLPs, but most studies have examined only a specific aspect of DLP success. Current findings also show inconsistencies and contradictions that confound our understanding of this important topic. As a result, an integrated and accurate understanding of DLP success is missing. In this paper, we adopt rigorous meta-analytic procedures to consolidate extant findings and reconcile inconsistencies in our understanding of DLP success. Additionally, we extend our meta-analyses to investigate the contingency effects of two moderating variables—user context and cultural context. The results provide a more comprehensive and accurate understanding of DLP success. Our study contributes to the literature by extending the theory on DLPs and information systems (IS) success and by providing insightful recommendations for practitioners
