Technology Factors Influencing the Adoption of Shrimp Farming
Commercial shrimp Culture has emerged as one of the most important sectors of the aquaculture industry in India: The cultured shrimps in the coimtry alone contribute to 50 per cent of the total shrimp exports from India. Much of this phenomenal successs has been attributed to the production and dissemination of a host of improved technologies starting from pond preparation till harvest of the cultured shrimps. The existing knowledge structure of the farmers is further enhanced when they are exposed to more scientific farming technologies containing more attributes of the innovation which influence their adoption process. It is frequently asserted that as farrriers gain in experience or obtain more accurate and scientific knowledge, their capacity to manage shrimp ponds in a more sustainable way is enhanced. (Saengnore and Lebel, 2002). The technology adopted ranges from traditional to improved, traditional within the coastal regulation zone and extensive shrimp farming outside the coastal regulation zone (Anon. 2002)
Perceptions of rubber growers on information technology enabled rubber export system
The Expert system for plant protection of rubber was developed using Visual Basic 6. O. The computer based Rubber
Expert System thus developed was abbreviated as RUBEX-04. Perceptions of Rubber Growers on Information
Technology enabled Rubber Expert System was studied. It was evident that, majority of the respondents (60.83 per
cent) were found to have high level of perception about modern information communication technologies, followed
by 21.67 per cent with medium and remaining 17.50 per cent with low level of perception of modern information
and communication technologies. It could be exonerated from the study that slightly less than three-fourth of the
respondents reported that they were most satisfied with the diagnostic path which was sequential and logic in
RUBEXS-04. A majority (81.67 per cent) of the respondents were most satisfied about the correct conclusion
provided by the RUBEXS-04. More than half of the respondents were most satisfied that, photographs helped them
to confirm the incidence of disease and pests. Most of the subjects preferred the Expert System for other technologies
of rubber like, latex preservation and processing, tapping and yield stimulation and soil management, in addition
to RUBEXS-04
Monitoring edge-geodetic sets in graphs
We introduce a new graph-theoretic concept in the area of network monitoring.
In this area, one wishes to monitor the vertices and/or the edges of a network
(viewed as a graph) in order to detect and prevent failures. Inspired by two
notions studied in the literature (edge-geodetic sets and
distance-edge-monitoring sets), we define the notion of a monitoring
edge-geodetic set (MEG-set for short) of a graph as an edge-geodetic set
of (that is, every edge of lies on some shortest path
between two vertices of ) with the additional property that for every edge
of , there is a vertex pair of such that lies on
\emph{all} shortest paths between and . The motivation is that, if some
edge is removed from the network (for example if it ceases to function),
the monitoring probes and will detect the failure since the distance
between them will increase.
We explore the notion of MEG-sets by deriving the minimum size of a MEG-set
for some basic graph classes (trees, cycles, unicyclic graphs, complete graphs,
grids, hypercubes,...) and we prove an upper bound using the feedback edge set
of the graph
Effectiveness of expert system on knowledge retention
Artificial intelligence based computer programmes called Expert System has received a great deal
of attention throughout the world, due to its impressive problem solving capability in a variety of fields.
For the present study, an expert system named as RUBEXS-04 was designed to simulate the pest and
disease diagnosing behaviour
Perception of attributes of shrimp farming technologies by shrimp farmers
During the last decade, shrimp aquaculture has become a major sector
of fish farming in terms of space occupied and of inarket value. In
India, commercial shrimp farming ,tan ed gaining roots oflly during
the mid eighties. The boom period of commercial scale shrimp culture
in India started in 1990 and the bust came in 1995-96, with the outbreak
of viral disease
Relationship between profile characteristics and knowledge gained
Indian Agriculture has made
impressive strides in the development of new
plant varieties, cultivars; hybrids and
production and standardization of plant
protection techniques
Information utilization behaviour and constraint analysis among shrimp farmers
Information utilization behaviour and constraint analysis among 60 selected
Slzrimp farmers of Nellore district of Andhra Pradesh was studied. The findings
of the study revealed that private consultants followed by feed technicians
were the most important sources of information utilized by 76.67 per cent and
71.67 per cent of Shrimp farmers. Among constraints, disease incidence, poor
quality of seeds and lack of quality control agencies were expressed by 81.67,
63.33 and 65.00 per cent of the respondents. Among the suggestions offered by
the Shrimp farmers, setting up of disease diagnostic centers, seed certifying
agencies and quality con trol agencies for regulating the quality of chemicals
accoreded top priority
Involvement of extension personnel in implementing social forestry programmes
In a country like India, where the population is high and resources are limited, social forestry is an instrument for
rural development, particularly for the poor people. Thus social forestry is identified as a forestry of the people, by
the people and for the people
A study on the knowledge gain related to skills, knowledge retention and symbolic adoption using expert system among rubber growers
Artificial intelligence based computer programmes called Expert System has
received a great deal of attention throughout the world, due to its impressive
problem solving capability in a variety of fields. For the present study, an Expert
system RUBEXS-04 was designed to simulate the pest and disease diagnosing
behaviour of human expert in rubber trees
