Distributed Recovery In Applicative Systems, Frank C. H. Lin, Robert M. Keller Aug 1986

Distributed Recovery In Applicative Systems, Frank C. H. Lin, Robert M. Keller

All HMC Faculty Publications and Research

Applicative systems are promising candidates for achieving high performance computing through aggregation of processors. This paper studies the fault recovery problems in a class of applicative systems. The concept of functional checkpointing is proposed as the nucleus of a distributed recovery mechanism. This entails incrementally building a resilient structure as the evaluation of an applicative program proceeds. A simple rollback algorithm is suggested to regenerate the corrupted structure by redoing the most effective functional checkpoints. Another algorithm, which attempts to recover intermediate results, is also presented. The parent of a faulty task reproduces a functional twin of the failed task. …

Genesis Of An Expert System For Umr Degree Auditing, Ruth Sue Dare, Arlan R. Dekock Jul 1986

Genesis Of An Expert System For Umr Degree Auditing, Ruth Sue Dare, Arlan R. Dekock

Computer Science Technical Reports

This paper describes the features, design, and development of an expert system for degree auditing at the University of Missouri--Rolla. It summarizes artificial intelligence as it is known today while specifically addressing expert systems. It describes selected expert systems currently in existence.

The present audit procedure utilized at the University of Missouri--Rolla is discussed. A description is given of the design and development of an expert system, written in LISP, to conduct a degree audit. Finally there are concluding remarks which include an analysis of the system and a discussion of possible system enhancement.


A Computerized Audio-Visual Speech Model, Joaquin Alberto Vila Ruiz, Arlan R. Dekock Jul 1986

A Computerized Audio-Visual Speech Model, Joaquin Alberto Vila Ruiz, Arlan R. Dekock

Computer Science Technical Reports

This thesis describes an expert system able to animate (graphically) and reproduce (acoustically) a text in any language which uses the Latin alphabet. A rule editor has been developed to create and modify the set of letter-to-sound rules of the target language. A parser has been implemented to apply the set of rules and translate text-to-speech. Each phoneme has a unique sound and thus requires its particular positioning of the vocal organs which are displayed in two different projections: a front view and a profile cross view of a human face in synchronization with the output sounds of the speech …

Making Mail Friendlier: Adding Macintosh Features And Multimedia Documents In Unix Mail, John R. Meier May 1986

Making Mail Friendlier: Adding Macintosh Features And Multimedia Documents In Unix Mail, John R. Meier

Dartmouth College Undergraduate Theses

This paper describes a Macintosh application which acts as a front-end to Unix mail. Features of the Macintosh interface such as icons, menus, and windows replace the command driven interface. Complicated editing commands are replaced with mouse selection and cut, copy, and paste. Message can be composed of text, pictures, and any Macintosh file, because they are encoded into plain text, sent through the mail system,and then unencoded by the receiving end. The designs of the mail server and communications interface are such that mail servers and communications other than Unix mail and a serial line may be easily implemented.

A Semantic Basis For Parallel Algorithm Design, Roger E. Eggen, John R. Metzner May 1986

A Semantic Basis For Parallel Algorithm Design, Roger E. Eggen, John R. Metzner

Computer Science Technical Reports

As computing demands increase, emphasis is being placed on parallel architectures- To efficiently use parallel machines, software must be designed to take advantage of these machines. This research concentrates on an abstraction of algorithm design to permit the expression of parallel programs. The abstraction emphasizes thought about algorithms at a high level as opposed to algorithm implementation at a statement level. A model based on data flow allows algorithm expression using flow diagrams. The model specifies operating system requirements that support parallel programming at a module level. Paths are used to carry data between modules. Data enter modules through ports. …

Deterministic Linear Predictors For Bit Rate Improvement, Dhanvant H. Goradia Apr 1986

Deterministic Linear Predictors For Bit Rate Improvement, Dhanvant H. Goradia

Electrical & Computer Engineering Theses & Dissertations

This thesis addresses the application of deterministic linear predictor s for telemetry based systems. Deterministic linear predictors are considered as a viable alternative to block transform coding in order to achieve bit rate reduction. A method of calculating the predictor coefficients of a deterministic linear predictor is presented. The system model is developed parametrically with respect to the bandwidth, polynomial order, signal class and predictor length. Two classes of signals, deterministic and random are analyzed and bounds on the performance of the deterministic linear predictor are established. A family of six pole Butterworth filters are used as presample filters in …
