purpose: libraries and information centers as information storage and retrieval systems can develop with the adoption of cybernetics rules. this paper discusses system dynamics, control, feedback, and other cybernetic concepts especially in information storage and retrieval systems. methodology: this study is a review intending to find what cybernetics and lis have in common especially in the f...

introduction: for many years, ontologies have been available in many different forms, for example: classification schema, thesauruses, authorized vocabularies, terminologies and dictionaries. terminology and knowledge resources are essential components of interoperability among disparate systems. so, this paper considered the ontology of umls (which was prepared by national library medicine of ...

The main objective of this study is to reduce the retrieval time of a list of products by choosing the best combination of storage and retrieval rules at any time. This is why we start by implementing some storage rules in an Automated Storage/Retrieval System (Automated Storage and Retrieval System: AS/RS) fitted with a gravity conveyor while some of these rules are dedicated to storage and ot...

Automated storage and retrieval systems (AS/RSs) are material handling systems that are frequently used in manufacturing and distribution centers. The modelling of the retrieval–travel time of an AS/RS (expected product delivery time) is practically important, because it allows us to evaluate and improve the system throughput. The free-fall-flow-rack AS/RS has emerged as a new technology for dr...

background: there are many studies focused on long or short storage time of epididymal sperm (eps) of different species. there are limited studies on preservation or cryopreservation of the domestic goat eps. objective: the aim of the present study was to evaluate the effects of ex vivo cold-storage on freezing of eps from goat (capra hircus). materials and methods: in a split-plot design the c...

Packed bed units generally, represent the most suitable storage units for air heating solar systems. In these systems the storage unit receives the heat from the collector during the collection period and discharges the heat to the building at the retrieval process. A method for sizing of packedbed storage in an air heating system is represented. The design is based on the K-S curves, which hav...

introduction: the manual and paper-based process of production and storage of medical records in iran have led to difficulties in filing and retrieval of the medical records. one of the usual solutions is using computerized medical records via electronic storage of paper-based medical records. the aim of this study was to recognize using computerized medical records in nine selected hospitals. ...

Automated storage and retrieval systems are warehousing systems that are used for the storage and retrieval of products in both distribution and production environments. Shuttle based storage/retrieval systems are composed of elevators with lifting tables that are attached on a mast, shuttle carriers, buffer positions and the storage racks. It is observed that the shuttle based storage/retrieva...

this study aimed to describe the concepts and characteristics of wilson's information seeking behavior model, as the highly cited pattern in information seeking behavior debates and tracing its completion, expansion and development process. wilson's information seeking behavior model is the base for other subsequent related models. it has been the highly cited model amongst other information se...
