This paper proposes a Self-Adaptive Interactive Navigation Tool (SAINT), tailored for cloud-based vehicular traffic optimization in road networks. The legacy navigation systems make vehicles navigate toward their destination less effectively with individually optimal navigation paths rather than network-wide optimal navigation paths, especially during rush(More)
Inspired by the advancement of vehicular networks and increasing concerns on driving safety, this paper proposes a framework of Context-Awareness Safety Driving (CASD). In vehicular networks, vehicles communicate with each other and share a variety of information. By utilizing those capability, CASD provides vehicles with a class-based safety action plan(More)
Clinical guidelines suggest that suspicious pigmented lesions of the plantar or palmar area require biopsy for early detection of acral melanoma. We present here a case of acral lentiginous melanoma in which various melanocytic atypia was observed at each biopsy site, including focal melanocytic proliferation. We suggest that this atypical melanosis is part(More)
One of today’s most important developing wireless technologies is Cognitive Radio (CR). In our current fixed-assignment spectrum management policy, much of the available frequencies go unused. CR aims to make use of this unutilized space to provide wireless broadband services. This paper aims to give a background to CR and describe the key players in(More)
Simple benign tumors can present as part of a syndrome with substantial mortality. Fibrofolliculomas are benign skin tumors most often associated with the Birt-Hogg-Dubé syndrome (BHDS). The most life-threatening complication of this syndrome is renal cancer and other major features include multiple lung cysts and spontaneous pneumothorax. We present the(More)
BACKGROUND There are several available treatments for vitiligo, but measurement of their therapeutic efficacy is not standardized and is somewhat arbitrary based largely on the global impression of the overall response. The purpose of this study was to develop a quantitative method for evaluating the treatment response of vitiligo measuring changes in area(More)
In order to support efficient data services on vehicular networks, we propose a Data-oriented Cluster-based Media Access Control Protocol (DCMAC). For Intelligent Transportation Systems (ITS), the demand for data services is increasing. Furthermore, most of vehicles will be equipped with Dedicated Short-Range Communications (DSRC) devices in the near(More)
Simulation is a common method used to examine the models and protocols before they are implemented in real systems. Vehicular networks present different characteristics which render most of their simulations inapplicable to real-world Vehicular Ad Hoc Networks. In these days, the important advancement has been made toward the realistic simulators. OMNeT++,(More)
