1 Motivation With the advent of networking and high-powered workstations, and the rise of end-user computing alongside the traditional centralised computing model, the heterogeneous network is emerging as the most signiicant platform for many computing activities. A heterogeneous network consists of a number of resources (e.g. workstations, leservers, database engines and computation nodes) int...

Impervious surface information is an important indicator to describe urban development and environmental changes. The substantial increase in impervious area will have a significant impact on the regional landscape environment. Therefore, timely accurate acquisition of large-scale percentage (LISP) great significance for management ecological assessment. However, previous LISP estimation method...

It is well known that dynamic typing in languages like Lisp is costly in terms of performance. Besides the cost of tag checking, the other major source of ine ciency comes from the need to place and retrieve data from dynamically allocated objects, i.e. boxing and unboxing. This makes it unacceptable in general to write numerical code in Lisp. Such programs involve \tight" loops in which boxing...

The Common Lisp Interface Manager (clim) provides a layered set of facilities for building user interfaces. These facilities include a portable layers for basic windowing, input, output services, and mechanisms for constructing window types and user interface components; stream-oriented input and output facilities extended with presentations and context sensitive input; and a gadget-oriented to...

We have implemented a comprehensive constraint-based programming language as an extension to Common Lisp. This constraint package provides a uniied framework for solving both numeric and non-numeric systems of constraints using a combination of local propagation techniques including binding propagation, Boolean constraint propagation, generalized forward checking, propagation of bounds, and uni...

Next Generation Internet points out the challenge of addressing ―things‖ on both a network with (wired) and without (wireless) infrastructure. In this scenario, new efficient and scalable addressing and routing schemes must be sought, since currently proposed solutions can hardly manage current scalability issues on the current global Internet routing table due to for example multihoming practi...

Due to its importance in security, syntax analysis has found usage in many high-level programming languages. The Lisp language has its share of operations for evaluating regular expressions, but native parsing of Lisp code in this way is unsupported. Matching on lists requires a significantly more complicated model, with a different programmatic approach than that of string matching. This work ...

Recent advances in web technologies and the availability of robust Lisp libraries supporting them have made it possible to think of new ways of understanding and debugging large applications. In this paper, we will discuss two basic ideas for assessing and verifying the behaviour of Lisp programs. First, we propose to use a web browser for graphically displaying debug output in a similar but mo...

Linear logic has been proposed as one solution to the problem of garbage collection and providing efficient "updatein-place" capabilities within a more functional language. Linear logic conserves accessibility, and hence provides a mechanical metaphor which is more appropriate for a distributed-memory parallel processor in which copying is explicit. However, linear logic's lack of sharing may i...
