User Studies In Connection With The Development Of A Decentralized Library Network, Nancy Fjallbrant, Olof Friberg

Proceedings of the IATUL Conferences

This paper examines the development of university departmental libraries in Scandinavia, and traces the influence of the German seminar libraries. This has led to the establishment of a number of library networks. Financial restraints have resulted in a number of studies of departmental library networks, with a view to possible rationalization. This paper describes studies of the attitudes of library users, at Chalmers University, towards computerization of literature resources and cooperation between the main library and the departmental libraries. It was shown that users were apprehensive of centralization and negative to any increase in administrative processes. At the same time …

Communicating Scientific Information Through A University Library Network, Dennis Shaw

Proceedings of the IATUL Conferences

Besides the widely accepted connotation of primary and secondary sources of scientific information it is postulated that a tertiary source may be identified. These three categories are defined and their role is related to (i) the pursuit of fundamental research at the frontier of knowiedge, (ii) the assimilation of the established discoveries into the traditional body of scientific literature and (iii) archiving for posterity.

It is no longer possible completely to separate these categories nor to identify distinct media responsible for information transfer and storage. However, we can identify a hierarchy of media and each element within the hierarchy can …

Libraries And The Communication Of Information: The Jamaican Situation, Yvonne T. Lawrence

Proceedings of the IATUL Conferences

Libraries and information systems in Third World countries are often neglected as they are not considered priority areas. To create an environment for the communication of information, not only must library and information services be developed - illiteracy must also be eradicated.

Jamaica has taken positive action to achieve these goals through the Jamaica Movement for the Advancement of Literacy (JAMAL) and by the appointment of a Council to make recommendations for the co-ordination of is lands' library and information services. A Plan proposing a group of networks, has been formulated by the Council, and has been adopted by the …

Communication With The Third World Countries, J. S. Musisi

Proceedings of the IATUL Conferences

Communication is the means by which information is transmitted and shared between 'two people' in order to enable them increase their knowledge. Within the framework of Unesco's new economic order, therefore, communication of information aims at providing facilities by which information should be shared universally through exchange of knowledge and experiences. The ultimate purpose of this economic order is to bring about human understanding, cooperation, and betterment of the quality of life.

Communication of information would not be a reality, however, if knowledge were not recorded, acquired, organized and disseminated for use. High premium in this respect therefore is placed …

Some Problems And Proposals For Communication In Mechanical Engineering, V. Jarc

Proceedings of the IATUL Conferences

HAEFFNERS MODEL, RESEARCH POLICY, INFORMATION FLOW, COMMUNICATIONS ABILITY, COMMUNICATION MEDIA MIX, INFORMATION MINDEDNESS DATABASES, INSPEC, ISMEC, MECHEN, DOMA, COMPENDEX, SAIDC-ST

Haeffners model of information flow and communication between research policy and implementation activities was transferred on integrated information flow between research, education, consuiting and informatics on one side, and the end-user on the other side.

For information flow neither the availability of documents, computers and communications, nor the information mindedness are sufficient, but the human activity is dominant.

Databases are in different fields of application differently aggregated and representative (Comparison between CHEMABS, INSPEC, ISMEC, COMPENDEX).

The information field in mechanical …

Poster Sessions As A New Viewpoint Of Scientific Communication - General Problems And Library Aspects, Dieter Schmidmaier

Proceedings of the IATUL Conferences

In the true sense the word POSTER designates a free, mostly decorative artistic form using displaying means of expression and being published in large editions.

POSTERS are already found in feudalism. Today they represent a popular branch of art and are frequently used for different decorating purposes, e.g. in rooms.

POSTER SESSIONS have made their way into scientific communication.

Scientific events, as conferences, congresses, symposia, colloquies, round tables etc. may be, are special ways of communieation. The advantages of such events {called conferences for short) are

• the actuality of the information given
• the possibility of an immediate exchange of ideas. …

Based on simplified models used by engineers for the design of telecommunication systems, an approach of the complex process of human communication is given. Some general concepts like information, analog/digital, noise, real time, network and information quality are introduced and commented.

Communicating With The New Electronic Libraries, Charles T. Meadow

Proceedings of the IATUL Conferences

New library and publishing technological developments are discussed from the point of view of how they will affect a library searcher of the future. Any library can become the entry point to a world-wide network of libraries, making almost all the world's literature available to any searcher. This, in turn, imposes requirements for better means of control of a search and better terminals, as well as a change of focus on the part of the library. Libraries are seen as developing into communications centers whose primary mission is helping users solve search problems, rather than repositories of information packages.

A Technique To Determine Which Crop Development Stages Can Be Estimated From Spectral Data, V. J. Pollara, V. C. Vanderbilt, C. S. T. Daughtry

LARS Symposia

Estimates of crop development stage by remote sensing techniques are potentially more cost effective for large areas than present labor intensive estimates. Here, discriminant analysis for identifying crop development stage using multispectral data is discussed. The data analyzed were Exotech 100 measurements in four wavelength bands (.5-.6, .6-.7, .7-.8, .8-1.1 um) over field plots of soybeans and corn in West Lafayette, Indiana. Different row spacings, soils, plant populations, planting dates, soybean cultivars and crop years (1978, 1979, 1980) increased the generality of the data set.

Results show that development stage classes at the beginning and end of the growing, season …

Processing System Techniques For The 80'S, Roger A. Holmes

LARS Symposia

Increased spatial resolution of oncoming systems such as Thematic Mapper and the French SPOT, plus experience gained in the LANDSAT MSS lead to a requirement to understand the error sources in the scene-to-data tape portion of a remote sensing system. An evaluation of this portion of the system and its effects on processing remote sensing data derived therefrom is presented. Discussion is limited to passive sensors in the reflective portion of the spectrum.

Digital Correction Of Solar Illumination And Viewing Angle Artifacts In Remotely Sensed Images, Tsutomu Shibata, Werner Frei, Mark Sutton

LARS Symposia

We seek to understand and correct shading artifacts caused by varying solar illumination conditions and different viewing angles in remotely sensed images. A synthetic image simulating the shading effects for the sun angle and viewing angle as a real image, is generated using a terrain reflectance model and digital elevation data. A good correlation is obtained between the real and synthetic images. The artifact correction is then made, and a resulting image shows useful information that is not apparent in the original image.

We also present a three-dimensional perspective representation of a terrain with a corresponding aerial photograph mapped on …

Derivation Of Shallow Ocean Bottom Reflectance Values From Color Aerial Photography, D. J. Gerson, L. K. Fehrenbach, K. R. Piech, D. W. Gaucher

LARS Symposia

An alternative to the field survey method of acquiring hydrographic data is described. The technique involves the use of digitized color aerial photography in the derivation of the percentage of reflectance of shallow ocean bottom materials. These spectral reflectance values can then be used in an algorithm for calculating water depths. The reflectances that were derived in this study show a close relative comparison to ground truth information. After a discussion of the causes of discrepancies between derived and actual reflectance values, it is concluded that this method of data acquisition merits further investigation due to its high geometric fidelity, …

Evaluation Of A Segment-Based Landsat Full-Frame Approach To Crop Area Estimation, M. M. Hixson, S. M. Davis, M. E. Bauer

LARS Symposia

Accurate and timely crop production information is a critical need in today's economy. During the past decade, satellite remote sensing has been increasingly recognized as a means for crop identification and estimation of crop areas. The Landsat multispectral scanner (MSS) records as a single data point (pixel) a region on the ground about one acre (0.5 ha) in size. When estimates of crop areas are desired for large regions, a statistical sampling scheme is required as it is not feasible to examine all of the pixels in the region of interest. The development of a sampling strategy which is both …

Presented here is an overview of the registration system developed, along with the study results that led to the choices of techniques incorporated.

Although much previous work exists in this area, it is believed that some of the methods and findings are new. It …

Physical Principles Of Local Heat Therapy For Cancer, Charles F. Babbs, David P. Dewitt

Weldon School of Biomedical Engineering Faculty Publications

Local hyperthermia therapy for cancer can produce selective heating of solid tumors on the basis of known physical laws. If energy is deposited in the general region of the tumor, temperature tends to develop in the tumor higher than that in surrounding normal tissues. The goal of therapy is to achieve cytotoxic temperature elevations in the tumor for an adequate period of time, without damaging nearby normal tissues. Several modalities exist for local heat treatment, of which radiofrequency and ultrasound offer the most promise for controlled, localized heating at depth. A paucity of blood flow in the tumor compared to …
