Users can access anywhere and anytime to the broad set of value-added Internet services, which are delivered by
3、means of the IP protocol. In this context, 3GPP is currently developing the IP Multimedia Subsystem (IMS), as a key element that allows to evolve from the ubiquitous access to the Internet services towards a next generation network model, by providing a set of essential facilities such as session co
4、ntrol, QoS, charging and service integration. Nevertheless, several open issues still need consideration before the future Internet becomes real, such as supporting user mobility in IP networks. Although mobility support in the Internet is receiving much attention, IMS networks present inherent part
5、icularities that require further analysis. The solutions proposed so far for IMS do not support mobility transparently to the end-user applications, or address the problem by introducing complex changes to the IMS infrastructure. This paper presents TRIM, an architecture for transparent IMS-based mo
6、bility. TRIM supports mobility in IMS networks transparently to the end-user applications, which are unaware of the handover management procedures executed between the mobile node and the network. We have performed several experiments with a TRIM prototype, using a real IMS testbed with 3G and WLAN

10、Smartway” next-generation roadways, which provide a variety of services through the use of advanced ITS technologies. In recent years, the National Institute for Land and Infrastructure Management (NILIM), part of the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), has conducted publ
11、icprivate joint research on next-generation road services using ITS technologies. Field operational tests (FOTs) of services including forward obstacle information provision and merging assistance using 5.8 GHz dedicated short range communication (DSRC) were conducted on the Tokyo Metropolitan Expre
12、ssway through FY2007. In FY20082009, FOTs were conducted in three major metropolitan areasTokyo, Nagoya, and Keihanshin (Kyoto, Osaka, and Kobe)to promote future deployment nationwide. These included tests of information provision services to alert drivers to forward obstacles hidden beyond the cres

18、ss Through Movement lessons were transcribed and the contents were analysed. An intercoder reliability study was undertaken. ResultsThe content analysis revealed that the classes used motor skill acquisition elements of internal feedback, repetition and variability of practice using an exploratory l
19、earning approach. Postural control skills of intersegmental coordination of ankle/hip/trunk synergies were practised, with control of the centre of mass over the base of support explored in anterior/posterior, medio/lateral, diagonal, rotational and circular directions. Key findings were the extensi

ConclusionThe Awareness Through Movement lessons contained many elements consistent with current theories of motor skill acqui

The methodology used in this study may provide a useful model for similar investigations into other balance training approaches.Article OutlineIntroductionMethods

25、est approaches for capturing and permanently storing gases that can contribute to global climate change. The Regional Carbon Sequestration Partnerships (RCSPs) are tasked with determining the most suitable technologies, regulations, and infrastructure for carbon capture, transport, and storage in th
26、eir areas of the country and parts of Canada. The seven partnerships include more than 350 state agencies, universities, national laboratories, private companies, and environmental organizations, spanning 42 states, two Indian nations, and four Canadian provinces. The Regional Partnerships initiativ
27、e is being implemented in three phases: Characterization Phase (20032005): The objective was to collect data on CO2 sources and sinks and develop the human capital to support and enable future carbon sequestration field tests and deployments. The completion of this Phase was marked by release of the
28、 Carbon Sequestration Atlas of the United States and Canada-Version 1 which included a common methodology for capacity assessment and reported over 3,000GT of storage capacity in saline formations, depleted oil and gas fields, and coal seams. Validation Phase (20052009): The objective is to plan and
29、 implement small-scale (1 million tons of CO2) Carbon Capture and Storage (CCS) projects, which will demonstrate that large volumes of CO2 can be injected safely, permanently, and economically into geologic formations representative of large storage capacity. Even though the RCSP Program is being im
30、plemented in three phases, it should be viewed as an integrated whole, with many of the goals and objectives transitioning from one phase to the next. Accomplishments and results from the Characterization Phase have helped to refine goals and activities in the Validation and Deployment Phases. The R
31、CSP Program encourages and requires open information sharing among its members by sponsoring both general workshops and meetings to facilitate information exchange. Although each RCSP has its own objectives and field tests, mutual cooperation has been an important part of the Program thus far. The p
32、rimary goal of the RCSP initiative is to promote the development of a regional framework and the infrastructure necessary to validate and deploy carbon sequestration technologies within each Partnerships region.480 Event-driven architecture for decision support in traffic management systems Original

34、t systems for traffic management systems have to cope with a high volume of events continuously generated by sensors. Conventional software architectures do not explicitly target the efficient processing of continuous event streams. Recently, event-driven architectures (EDA) have been proposed as a
35、new paradigm for event-based applications. In this paper we propose a reference architecture for event-driven traffic management systems, which enables the analysis and processing of complex event streams in real-time and is therefore well-suited for decision support in sensor-based traffic control
36、systems. We will illustrate our approach in the domain of road traffic management. In particular, we will report on the redesign of an intelligent transportation management system (ITMS) prototype for the high-capacity road network in Bilbao, Spain.Article Outline1. Introduction2.

The objective of our study is to determine the optimal design of the productiondistribution network capable of fulfilling a predefined hydr
43、ogen demand. The design task is formulated as a multi-scenario mixed-integer linear problem (MILP) that Purchase$ 31.50considers the uncertainty associated with the coefficients of the objective function of the model (i.e. operating costs, raw materials prices, etc.). The novelty of the approach pre
44、sented is that it allows controlling the variation of the economic performance of the hydrogen network in the space of uncertain parameters. This is accomplished by using a risk metric that is appended to the objective function as an additional criterion to be optimized. An efficient decomposition m

The capabilities of the proposed modeling framework and solution strategy are illustrated through the application to a real case study based on Spain, for which val
