....implies a heterogeneous simulation by interoperating discrete (Queueing Systems) and continuous (System Dynamics) simulation techniques. Fishwick recently showed that every quasi continuous simulation technique can be mapped to a discrete event technique if the time increment is sufficiently small [Fishwick, 1995]. Our MultiSim environment generalizes this idea to a graphical simulation definition and execution environment [Peters et al. 1996] The kernel of MultiSim is a ConceptBase repository for simulation techniques. We developed a definition language for simulation techniques by which simulation ....

A. Fishwick [12]. Our simulation software serves as a compiler that translates a description file containing the query tree for the pipelining segment into a C sim source code that can be compiled to the respective executable. 5.4 Query Design The queries we want to investigate here are rightdeep pipelining ....

....environment to use. Any simulation language could have been applied: Modelica [30] Maisie [31] Simulink [32] ACLS [33] ModSim [34] Simscript [35] etc. Many of the simulators included in section 1.1. were built using this ap proach. For instance, in [7] the tools were built using Sim [36]. In [19] BONeS, a Block oriented Network simulator was used as the building tool [21] Another possibility included the use of a Hardware Description Language (HDL) HDLs are indispensable for computer and digital design. Presently, VHDL, Verilog and SDL are three of the most widely used ....

....the probe thread is run with lower priority than the build thread. Using this implementation technique, scheduling is done by the operation system. In order to compare floating probe to the conventional strategy, we designed and implemented an event driven simulator using the Sim package [Fis95]. The simulator is very detailed, i.e. it simulates each single page I O operation as well as each single tuple operation using the execution times from Table 1. According to the aforementioned strategy, the simulator assumes distinct build and probe threads, one of each per processor. 6.2 ....

....as the simulation is running. States of data buffers queues pipes (e.g. number of data input output pending) and values of state variables are also presented with bar graphs and tables. The most basic type of analysis is simply to look (either on line or off line) at the data and make inferences [8]. For instance, if output data exhibits a time dependent state variable value that demonstrates a damped oscillation, we may deduce that the system will gradually achieve a steady state after fluctuating for some initial time period [8] Figure 9 shows the animated simulation window of ASADAL SIM. ....

....However, notable works in animation such as OBLIQ 3D [15] TBAG [4] and UGA [29] are initiating the drive to produce such terms. The graphics community has not yet begun to use many of the latest ideas proffered by the simulation community for system development, such as multi model modeling [7] and process abstraction [5] These high level techniques permit users to integrate many modalities into one system. Common themes, such resource allocation and contention [22] are also missing from the works of the graphics community. Algorithms for resource contention are useful to manage ....

....higher and lower extensibility. Full object oriented simulation systems include Smalltalk (Goldberg and Robson 1989) Modsim III (Belanger and Mullarney 1990) and Simple (Geuder 1995) C based simulation packages include C Sim (Little and McCue 1994) C CSIM17 (Schwetman 1995) and Simpack (Fishwick 1995). 1.2.2 An Object Oriented Simulation Approach OOS deals directly with the limitation of extensibility by permitting full data abstraction as well as procedural abstraction. Data abstraction means that new data types with their own behavior can be added arbitrarily to the programming language. ....

....graph, and the right sub graph, referred to as the fixed posture graph Figure 4: Some of the postures a soldier can take in DIS right foot, and in the right sequence, it is waving its left arm. The motion on individual arcs of the graph is similar to the notion of animation tracks described in [6]. Here we are putting many of the tracks together, with common starting and ending frames, to form the posture graph. The system we built consists of two distinct parts: 1) the off line motion data generator, and 2) the on line real time playback mechanism, running in a high performance IRIS ....

....process is to record the resulting motions of the human figures. The recorded motion for one transition is referred to as a channel set (where each joint or figure position is referred to as a channel; the channel is indexed by time) Again, the channel set is analogous to an animation track in [6]. For each LOD human figure, a homogeneous transform is recorded, representing figure position relative to a fixed point, and for each joint, the joint angles are recorded (one angle per DOF) Also for joints, the composite joint transform is pre computed and stored as a 4x4 matrix (which can be ....

....4 Discussion We have tested several scheduling policies that we proposed for the chain structured adaptive transactions via simulation [Dogdu 96] A simulation system is developed in a Unix environment based on the discrete event simulation technique. We utilize the SimPack simulation toolkit [Fish 95] Currently we are extending the system to handle concurrent execution of subtransactions with a lock based concurrency controller. We will then be able to test extensively different scheduling policies for adaptive transactions. We have so far used only a limited number of features from extended ....

....cellular automaton, problems arise with this attempt when individual organisms may move around in space within one time phase of the system such that they have to diffuse through several cells. Some classical solutions to the problem of moving within a cell space can be found e.g. in chap. 7 of (Fishwick, 1995). A modified and more general solution for a modelling of diffusion can be based on the description of a cell s behaviour by reactions to different events within one time phase. So, it is possible to model several changes of cell states within one time phase of the system without synchronisation ....

....and strengthens the relationship of model to program [5] The physical aspect of OOPM reflects a model design philosophy that recommends that models, components, and objects should be patterned after the structure and attributes of corporeal objects. Within OOPM , programs are multimodels [6, 8, 9, 10]. A multimodel is defined as a hierarchically connected set of dynamic behavioral models, where each model is of a specific type and the set of models may be homogeneous or heterogeneous [5, 8] The basic dynamic behavioral model types are numerous and include Conceptual Model (CM) Finite State ....
