Two new techniques for multi-method dispatch are presented, both sufficiently general to apply to reflexive languages where methods and types can be added and removed at run-time. However, these techniques also apply to non-reflexive languages. One of the techniques operates by performing projections onto single-receiver dispatch tables, and thus benefits from existing research into single-rece...

A collection of algorithms and data structures are presented which provide incremental dispatch table modiication. Incrementally modiied dispatch tables allow table-based dispatch techniques to be used in reeexive, dynamically typed, single-receiver languages with type/implementation-paired multiple inheritance. By storing a small amount of information, the algorithms can incrementally maintain...

A hybrid wireless sensor network consists of both static sensor and mobile sensor nodes. Static sensors monitor the environment and report events occurring in the sensing field. Mobile sensors are then dispatched to visit these event locations to conduct more advanced analysis. The sensing field may contain obstacles. A big challenge is how to dispatch the mobile sensor to the event location wi...

This paper presents a demonstration of solving combined economic and emission dispatch problems by using one of swarm intelligences, called particle swarm optimization. The objective of the combined problem can be expressed by taking both the total production cost and total emission into account with required constraints. Among potential intelligent search methods, particle swarm optimization i...

Mainstream object-oriented languages, such as C++ and Java1, provide only a restricted form of polymorphic methods, namely uni-receiver dispatch. In common programming situations, developers must work around this limitation. We describe how to extend the Java Virtual Machine to support multi-dispatch and examine the complications that Java imposes on multidispatch in practice. Our technique avo...

Economic load dispatch is one of the main functions of electrical power management systems. The main objective of economic load dispatch is to minimize the fuel cost while satisfying the required equality and inequality constraints. Economic Load Dispatch is a well known problem and has been a major concern for researchers and industrialists all around the world. The problem consists of divisio...

In a distributed environment, where a large number of computers are connected together to enable the largescale sharing of data and computing resources, agents, especially mobile agents, are the tools for autonomously completing tasks on behalf of their owners. For applications of large-scale mobile agents, security and efficiency are of great concern. In this paper, we present a fast binary di...

Candidates often tout their private sector experience when running for public office. Success in the business world, they argue, uniquely qualifies them for government work. In this paper, I test whether businessperson politicians govern differently from other types of leaders using data on over 25,000 Russian mayors and regional legislators. Analyzing both a close election regression discontin...
