Geology field trip is an important teaching step for the majors of geology, natural resources prospecting engineering and geographical sciences to learn geology knowledge and grasp field working skills. There are some problems in the traditional geology field trip teaching. Inspired by the Google Maps Street View, the author proposes applying the Image-Based Rendering (IBR), a branch of Virtual Reality...
We have been running summer computing camps at the University of Limerick, Ireland, since 2010. The three-day camps are offered to boys and girls aged 14 and up. During the summer of 2015 we ran two computing camps where we focused on strategy development for the ChainReaction board game with the jABC workflow modelling framework for the first time. In this paper we describe the freely available software...
Internet of Things (IoT) is becoming a hot topic in Computer Science, especially with the advent of smart appliances such as Nest thermostats, connected light bulbs, and other IP-enabled systems. In this paper we are proposing IoT-based framework to facilitate education of indoor localization. The proposed framework employs Arduino microcontroller boards connected with XBee radio modules to perform...
Big graphs are finding increasing applications in many science and engineering domains, such as computational biology, cybermanufacturing and social media. Graphs provide a very flexible mathematical abstraction for describing relationships between entities in complex systems. Real world graphs are characterized by high connectivity and high irregularity. Such non-uniform characteristics increase...
Thanks to the strength of crowdsourcing, there is a lot of useful information on StackOverflow, the most popular Question and Answer (Q&A) platform in software engineering area. This information can be treated as numerous URLs (Uniform Resource Locators), which can be categorized into URLs of Q&As and URLs in Q&As. The domain of former ones is Stack-Overflow itself,...
The fast development of sensing devices and radios enables more powerful and flexible remote health monitoring systems. Considering the future vision of the Internet of Things (IoT), many requirements and challenges rise to the design and implementation of such systems. Bridging the gap between sensor nodes on the human body and the Internet becomes a challenging task in terms of reliable communications...
Development of the Smart City has produced much data with attributions of timestamp and location, but in some applications like investigation of the large bomb explosion in New York, the government takes precedence to investigate the relation data from New York city rather than the whole Country, which prompts us to do some research works in computing partial graph more fast. So we propose SpatialGraphx,...
With the resource constraints of Internet of Things (IoT) devices, performance and energy efficiency have become an important IoT software design consideration while minimizing resource usages. To provide efficient communication for resource-constrained applications, several IoT protocols have been introduced, and yet there are few existing guidelines to help the programmer choose an appropriate communication...
This article assesses the risks posed by tsunamis to the global air transport system by estimating several associated parameters from socioeconomic-technological-environmental databases. Considering the risk of tsunami run-up events to exposed air transportation, we estimated the physical exposure of airports utilized in global aviation networks. We linked OAG timetable data on international passenger...
Plain text has always been the predominant medium for writing and editing programs for expert users. Text is powerful and flexible, but requires more careful manipulation than structural editors, such as those found in block-based environments. In addition, in textual editors programmers are responsible for managing detailed orthography and layout - when beginners work with text, significant time...
We present a generic framework for group activity recognition using simple non-obtrusive sensors. The proposed scheme is based on that group activity patterns can be derived from mining interval-based relationships between users' temporally overlapped actions. We leverage a hybrid architecture of probabilistic and logic knowledge that can capture the essence of the temporal dependencies, represented...
The demand of having a multi-window and multitasking option in Android devices has been an emerging topic among Android users, especially with the trends toward larger hand-held screen sizes. One option to meet this demand, is to use floating windows. This feature enables users to perform more than one task at the same time while sharing the same screen. Device screens can be divided into multiple...
Spearphishing is a prominent targeted attack vector in today's Internet. By impersonating trusted email senders through carefully crafted messages and spoofed metadata, adversaries can trick victims into launching attachments containing malicious code or into clicking on malicious links that grant attackers a foothold into otherwise well-protected networks. Spearphishing is effective because it is...
Stack Overflow is a popular community-based Q&A website that caters to technical needs of software developers. As of February 2015 -- Stack Overflow has more than 3.9M registered users, 8.8M questions, and 41M comments. Stack Overflow provides explicit and detailed guidelines on how to post questions but, some questions are very poor in quality. Such questions are deleted by the experienced...
With the universal application of software cluster systems, their reliability is drawing more and more attention from academia to industry. A cluster system is a kind of software load-sharing system (LSS) whose reliability is significantly dependent on system software. Therefore, traditional reliability analysis methods for hardware LSSs are not applicable for cluster systems. In this paper, we develop...
The Field Programmable Gate Arrays (FPGAs) are highly attractive options for hardware implementations of Bioinformatics algorithms as they provide physical security and potentially higher performance than software solutions. The Smith-Waterman algorithm is the most accurate local alignment algorithm for DNA and protein sequencing. However the existing parallel Smith-Waterman algorithm needs extra...
