The Western Lake Erie Basin has been targeted as a major contributor of non-point source pollution into Lake Erie largely due to its predominant land use; agriculture. An increased use of GIS among planners in watershed related issues is needed in order to improve their decision-making capabilities to address the overall health of the watershed. An online GIS system had been created for data sharing and management across the Western Lake Erie Basin. The object of this study was to conduct a survey examining the usage of GIS across the Western Lake Erie Basin in order to advance the knowledge of civic leaders, agency administrators, and planners involved in managing the watershed. Survey participants were asked about their current use of GIS, spatial data resources, data distribution, data sharing, data exchange, and future use of GIS. The survey analysis indicated that while the current online GIS system was a good start, there needed to be more training on how to use GIS among the watershed planning community.

Internet of Things is an emerging area and it visions an inter-connected world full of physical as well as virtual objects, devices, processes and services capable of providing a different lens on how to link them via the Internet. While Internet of Things as part of the Future Internet has been described as a paradigm that mainly integrates and enables several technologies and communication solutions a notable interest is to define how current standard communication protocols could support the realization of the vision. Within this context, we offer a state-of-the-art review on ad hoc and wireless sensor networks, near field communications, radio frequency identification and routing protocols as a mean to describe their applicability towards an Internet of Things realization. We conclude by presenting a brief case scenario to describe a future smart environment and illustrate its possible model architecture.

This report discusses the design and implementation of a software-based solution that will improve the data collection processes during the Pavement Condition Surveys (PCS) conducted by the State Materials Office (SMO) of the Florida Department of Transportation. This software replaces the prior method of Microsoft Excel spreadsheets with macro programming and integrates data from both the Departments Geographic Information System (GIS) and their legacy test section database. The software, known as the XPCS system, contains three components: a database of pavement condition, an office application used for planning and reporting, and a mobile application used for data collection and navigation.

在国外MVNO（移动虚拟网络运营商）市场的发展过程中，传统移动运营商对于MVNO的态度经历了根本性的转变：移动运营商先是大力反对MVNO的推出，然后逐渐接受了MVNO的存在，甚至采取积极的合作策略；与此同时，部分传统移动运营商也开始了自营MVNO的探索。

This chapter discusses the challenges, state of the art, and future trends in context aware environments (infrastructure and services) for the Internet of Things, which is defined as a world-wide network of uniquely identified self-organized and intelligent things. Intelligence means primarily the capability of things to be aware of the context in which they operate (time, geographic location, geographic dimension, situation, etc.) and to inter-cooperate with other things in the environment. The Chapter is structured in three sections. The first section, which frames the issues discussed in the rest of the chapter, is a systematic presentation of the most relevant concepts and aspects related to the infrastructure and services for the Internet of Things. The second section presents relevant research works in the infrastructure, and up to date solutions and results regarding the infrastructure and services. The third section presents future trends and research directions in the domain.

This paper describes the development of the Rutgers Interactive Lane Closure Application (RILCA), an interactive computer tool to plan lane closures for work zones. This tool provides traffic engineers with a computerized and easy-to-use lane closure application, along with other useful features. RILCA was developed with the Arc View geographic information system (CIS) software package as the main development environment. Arc View displays the interactive CIS map of the New Jersey Turnpike, Garden State Parkway, and other major freeways in New Jersey and its surrounding network. RILCA provides various analysis and visualization options to plan lane closures interactively, obtain traffic volume information, and conduct accident queries. RILCA was tested successfully, and New Jersey Department of Transportation (DOT) and New Jersey Turnpike Authority engineers now use it with all of the features presented in this paper. RILCA received an annual implementation award from the New Jersey DOT in 2009. The award recognized RILCA's usefulness and potential to improve the efficiency of traffic operations as a practical decision-support tool for lane closure decisions.

This report presents the state-level results of a spatial analysis effort calculating energy technical potential, reported in square kilometers of available land, megawatts of capacity, and gigawatt-hours of generation, for six different renewable technologies. For this analysis, the system specific power density (or equivalent), efficiency (capacity factor), and land-use constraints were identified for each technology using independent research, published research, and professional contacts. This report also presents technical potential findings from previous reports.
