The FLEX/REFLEX paradigm is applied to the description of a computer program system. The paradigm is shown to be relevant and appropriate to computer program systems and to advantageously display and structure the general hierarchical characteristics of computer program systems. Program systems characterized in the paradigm are described both holistically...
Disk space fragmentation is the proliferation of small and
unusable gaps. This problem is considered within the context of
IBM's VM operating system.
Facing this problem, researchers resorted to using algorithms
based on memory management techniques, such as placement
strategies (first-fit, best-fit, and worst-fit). Solutions based on these
algorithms do...
An active object system is a transition-based object-oriented system suitable for the design of various concurrent systems. An AOS consists of a collection of interacting objects, where the behavior of each object is determined by the transition statements provided in the class of that object. A transition statement is a...
This thesis discusses a special type of a versatile, distributed control system, the Taskmaster II. It includes a detailed specification of a readily realizable Taskmaster system utilizing a layered communication among units, oriented on the ISO OSI seven layer model. The specification was developed from the analysis of previous research...
FLEX1 is a general model processor, patterned after Klir's
General Sequential System Paradigm (Figure 1). Specifically, the
processor is a discrete time flux oriented realization of the general
paradigm and can process non-linear, non-stationary, environmentally
controlled state variable system models with explicit memory. The
current version is restricted to not...
Users interested in customizing their Primo installation are required to configure specific settings, files, and code during the View setup process. A consequence of this is that unique customizations are not easily sharable between institutions. With the release of the new Primo User Interface, Ex Libris has enabled institutions to...
The inefficiency of time-shared computer systems compared to
batch processing systems is in the time lost in swapping operations.
The larger the allocated quantum size, the less swap time is incurred.
In order to guard against intolerable response time while lengthening
the quantum size, the response time of a common...
Allegro is a network database management system being developed at Oregon State University. This project adds a user friendly query facility to the system. The user is presented with pictorial display of the network records and a query interface modeled on the Query-By-Example system. By request the user may be...
Behavioral modeling is increasingly an imperative component of system design as the systems under construction become more and more complex. Without behavioral modeling available to the modern designer, design and verification of these systems would be much more laborious. Additionally, with the increasing computational power of today's modeling and simulation...
