A validation study was conducted to study the performance on detection of underground void underneath pedestrian walkway by the use of ground penetrating radar (GPR). The experiment was carried out on a footpath which locates adjacent to the lateral support of a deep excavation works. 3 number of GPR scans were carried out, 7 nos. and 5 nos. of suspected voids and water leakage points from drain were...
The recent technological advances related to computing, storage, cloud, networking and the unstoppable deployment of end-user devices, are all coining the so-called Internet of Things (IoT). IoT embraces a wide set of heterogeneous services in highly impacting societal sectors, such as Healthcare, Smart Transportation or Media delivery, all of them posing a diverse set of requirements, including real...
Road transport vehicles (RTV) technologies, features and capacities are rapidly evolving, hence fostering innovative transport paradigms strongly impacting on all involved transport players. Current and unforeseen technological advances are pushing for creating a novel environment where road transport users can be empowered with tools enabling higher flexibility, bringing new opportunities, opening...
Service systems are a main focus of service research; the advancement of Service Science relies on a thorough understanding of how service systems work. While the service research literature offers a range of theories to examine service systems, empirical evidence is still scarce. This paper reports a recent study into universities, which are among the most common yet probably the least understood...
Knowledge-intensive services are prevalent in B2B environment involving complex problems and custom solutions. As such services consume and generate a large amount of information, knowledge-sharing mechanisms are required to capture, transfer and reuse information across projects. So far, with the advent of the internet, the business community has mainly focused on web-based technologies for knowledge...
A k-fold coloring of a graph G is an assignment of k distinct colors to each vertex of G so that adjacent vertices receive no colors in common. The k-th chromatic number of G,denote by chik(G), is the smallest number of colors needed to give G a k-fold coloring. Let mup(G) denote the p-Mycielskian of G. In this paper, we show that chik(mu(Wn)) = 3k + [k/3] + 1 (n is even, n ges 2k + 2 > 4). Moreover,...
Due to the progress of portable computing devices such as PDAs, cellular phones and small sized PCs, many personal navigation systems have been developed which navigate their users to display routes to given destinations. Those navigation systems mainly focus on the guidance for personal use. In this paper, we have developed a group navigation system, which provides facilities for (1) personally customizable...
