Traceroute is a networking tool that allows one to discover the path that packets take from a source machine, through the network, to a destination machine. It is widely used as an engineering tool, and also as a scientific tool, such as for discovery of the network topology at the IP level. In prior work, authors on this technical report have shown how to improve the efficiency of route tracin...

Increasingly interactions which entities have with each other are network bound. The entities, with which applications andservices need to interact, span a wide spectrum that includes desktops, PDAs, appliances, and other networked resources. These events encapsulate information pertaining to transactions, data interchange, system conditions and finally the search, discoveryand subsequent shari...

We study a facility location problem motivated by requirements pertaining to the distribution of charging stations for electric vehicles: Place a minimum number of battery charging stations at a subset of nodes of a network, so that battery-powered electric vehicles will be able to move between destinations using “t-spanning” routes, of lengths within a factor t > 1 of the length of a shortest ...

What is the best distribution strategy to ship materials from a source to multiple destinations on a regular basis? This is a common question confronting logistics planners in many industries. This paper examines this issue in the context of the ocean freight industry. In particular, we tackle the economics of freighting raw materials through a transshipment hub, and propose a method to synchro...

We describe the design and implementation of FastPass, a next-generation network architecture that thwarts bandwidth flooding attacks by providing destinations with finegrained control over their upstream network capacity. Prior attempts to achieve network flood resilience have required destinations to successfully receive an initial unprotected packet (capability-based designs) or have relied ...

Many forms of urban models are retail oriented, that is, they depend to some degree on the allocation of shopping expenditures to particular destinations. Such an allocation is usually undertaken with the aid of a production-constrained gravity model, although this type of model ignores the relationship between retail expenditure patterns and spatial competition and agglomeration forces. The ef...

Discussion of agglomeration and clustering in the tourist area life cycle (TALC) literature has not led to a corresponding change of the principal equation used to formalize the model. This paper proposes a modification that accounts for the synergies between the accommodation, entertainment, and other components of a tourist destination. The modified model is contrasted with the original TALC ...

In this study, the presence and management of social networks 78 tourist destinations were analyzed for development sustainable tourism, with particular attention being paid to Spanish smart destinations. The variables empirical analysis determined from a literature review, it was concluded descriptive analysis, correlation an variance, that although on internet notable, their inadequate It sho...

BACKGROUND Few neighborhood observational measures have been replicated by separate research teams in different cities. PURPOSE This study replicates the neighborhood active living potential observation measure in Saskatoon, Saskatchewan, Canada. METHODS Observers (n=5) participated in a 3-day neighborhood active living potential training session. Observers rated 60 neighborhoods in Saskato...

PURPOSE Examine the influence of destinations within walking distance of a residence and vegetation on walking trips and body mass index (BMI). DESIGN Cross-sectional analysis of data from residences with varying accessibility and greenness. SETTING Seattle, Washington. SUBJECTS Stratified random sample of residents, stratified by accessibility and greenness. RESPONSE RATE: 17.5 %, 529 re...
