Multilisp is a version of the Lisp dialect Scheme extended with constructs for parallel execution. Like Scheme, Multilisp is oriented toward symbolic computation. Unlike some parallel programming languages, Multilisp incorporates constructs for causing side effects and for explicitly introducing parallelism. The potential complexity of dealing with side effects in a parallel context is mitigated by the nature of the parallelism constructs and by support for abstract data types: a recommended Multilisp programming style is presented which, if followed, should lead to highly parallel, easily understandable programs.Multilisp is being implemented on the 32-processor Concert multiprocessor; however, it is ultimately intended for use on larger multiprocessors. The current implementation, called Concert Multilisp, is complete enough to run the Multilisp compiler itself and has been run on Concert prototypes including up to eight processors. Concert Multilisp uses novel techniques for task scheduling and garbage collection. The task scheduler helps control excessive resource utilization by means of an unfair scheduling policy; the garbage collector uses a multiprocessor algorithm based on the incremental garbage collector of Baker.

Sedentary behaviour is a major cause of poor health worldwide both through the direct effects of inactivity on health and indirectly via its contribution to obesity. Health and Community Design describes the role of the built environment as a potential contributor to physical inactivity …

Relativistic Quantum Fields

A motion-coupled visual environment prevents, reduces and/or treats motion sickness by sensing inertial motion and providing a corresponding evocative image for a subject to view. Inertial sensors may include accelerometers, gyroscopes or a variety of other different sensor types. A cross-coupling algorithm may be used to cross couple different sensed inertial motions. A variety of mapping schemes may be used to map sensed inertial motion to corresponding motion within the evocative scene displayed on the display. Applications include reducing motion sickness on passenger vehicles such as airplanes, trains and cars; on military vehicles such as ships, airplanes, helicopters and the like; and reducing “cybersickness” in the context of simulations on moving platforms.

Motion-coupled visual environment for prevention or reduction of motion sickness and simulator/virtual environment sickness

Although the programming language LISP was first formulated in 1960 [6], a widely accepted standard has never appeared. As a result, various dialects of LISP have been produced [4-12], in some cases several on the same machine! Consequently, a user often faces considerable difficulty in moving programs from one system to another. In addition, it is difficult to write and use programs which depend on the structure of the source code such as translators, editors and cross-reference programs.

This paper describes load balancing techniques for the Time Warp distributed synchronization technique for object-oriented simulation. The Time Warp system distributes objects across nodes and provides optimistic concurrency control. Our implementation is Lisp-based and executes on a network of UNIX-based workstations, where system load varies depending on the number of users and processes. This technique achieves a balanced load by first determining if the load is unbalanced. Then if it is unbalanced, the system must determine which machine is the most underloaded and migrate an object to that machine

Load Balancing Strategies for Time Warp on Multi-User Workstations

“Smartmat” (Smartmat Area Activity Monitor and Personnel Identification System) monitors and identifies people, animals and other objects that pass through a control volume. Among other attributes, the exemplary system implementation can count, classify and identify objects, such as pedestrians, animals, bicycles, wheelchairs, vehicles, rollerbladers and other objects, either singly or in groups. Exemplary Smartmat implementations differentiate objects based on weight, footprint and floor/wall pressure patterns such as footfall patterns of pedestrians and other patterns. The system may be applied to security monitoring, physical activity monitoring, market traffic surveys and other traffic surveys, security checkpoint/gate monitoring, traffic light activation and other device activation such as security cameras, and other monitoring applications. Smartmat may be portable or permanently installed.

The Bath Concurrent LISP machine is a general purpose multiprocessor designed for research in symbolic computation and expert systems. The system is particularly suited to tree structured computations with dynamic data requirements and complex interactions. It accepts conventional LISP programs, performs a data flow analysis on them, and creates a compiled module in which available concurrency is exploited. This paper presents an overview of the system hardware and software and the directions in which research is proceeding.
