On-the-go consumers require dynamic information, particularly "word of mouth, " to make better purchase decisions. A popular genre of mobile map services is travel/cuisine, which is a popular topic for bloggers as well. This study attempts to generate local cuisine hotspot maps through blog content mining. The main obstacle in doing this involves recognizing and extracting restaurants and...
As GPS devices show a great tendency to be popular, location based services such like instant POI finding become more and more important. On-the-go consumers require dynamic information, particularly ldquoword of mouthrdquo, to make better purchase decisions. To improve user experience on mobile POI finding in unfamiliar area, this study proposes a brand-new POI database comprising information extracted...
In this paper we design a high-sensitivity DVB-T (digital video broadcasting-terrestrial) system using dual receivers and silicon tuners. We have modified and utilized two receivers in our front end, each integrated with a tuner by using an OFDM (orthogonal frequency division multiplexing) structure to demodulate the receiving signal. Dual receivers compensate each other and improve the sensitivity...
Ad hoc networks are highly dynamic routing networks cooperated by a collection of wireless mobile hosts without any assistance of centralized access point. Secure Efficient Ad hoc Distance Vector (SEAD) is a proactive routing protocol, based on the design of Destination Sequenced Distance Vector routing protocol (DSDV). SEAD provides a robust protocol against attackers trying to create incorrect routing...
An ad hoc network is a highly dynamic routing network cooperated by a set of wireless mobile nodes without any assistance of centralized access point. ARIADNE is a well-known secure on-demand ad hoc network routing protocol. After finishing the route discovery protocol, it just finds one route for the source and the destination nodes. However, the intermediate nodes can't use that route to transmitting...
Traditionally, the minimum cost transshipment problems have been simplified as linear cost problems, which are not practical in real applications. Recently, some advanced local search algorithms have been developed that can directly solve concave cost bipartite network problems. However, they are not applicable to general transshipment problems. Moreover, the effectiveness of these modified local...
Lightweight Directory Access Protocol (LDAP) service is a new technology being applied on the Internet. On large-scale network systems using Transmission control protocol (TCP)/Internet protocol (IP), there is no standard suggested for single directory--certainly without one to be routinely used on the scale of intranets. LDAP service has many great features, such as providing quick and advanced search,...
