In this thesis I present a demand-driven pointer analysis for Java that aims at applications which require memory and time efficiency of the pointer analysis, such as tools for IDEs or JIT compilers. It furthermore allows clients to specify the precision needed and is context-sensitive and flow-sensitive. The demand-driven aspect of my approach allows the analysis to ignore irrelevant parts of ...

Recently, there has been much interest in performing demand-driven data-flow analysis in software development environments. Demand-driven analysis techniques compute data-flow fact(s) for a particular program point, rather than computing data-flow information for the entire program. The existing work in this area, however, assumes that the static call graph is available for the entire program. ...

The rapid increase in the number of cars has caused many problems such as “cruising for parking” and “parking illegally”. Demand-driven dynamic parking pricing mechanism is an effective method to dynamically regulate demand, thus reducing problems. In this research, we conducted a large on-street surveys business districts Beijing. A location choice model decision ru...

Up to now most of the existing water supply network analyses have been based on demand-driven simulation models. These models assume that nodal outflows are fixed and are always available. However, this method of simulation neglects the pressure-dependent nature of demand that is characterized by changes in actual nodal outflows particularly during critical events like major mechanical or hydra...

Collaborative tagging allows users to assign arbitrary keywords (or tags) describing the content of objects, which facilitates navigation and improves searching without dependence on pre-configured categories. In large-scale tagbased systems, tag recommendation services can assist a user in the assignment of tags to objects and help consolidate the vocabulary of tags across users. A promising a...
