In this paper, we investigate possible means of communication between plants and machines. Plants are capable of sensing various environmental information. In particular, Avocado trees have an apparent response to increasing draught level. We read out two different communication channels: morphological changes (leaf inclination) and electric potential of the stem (biopotential) by using distanc...

Plant species act as natural bioindicators of atmospheric pollutants. Plants can be used as bioassay systems for monitoring atmospheric pollutants. Plant injury symptoms, altered growth and reproductive pattern, changes in yield and/or productivity, and changes in species distribution can be used singly or in combination as monitoring devices. The results must be accepted as semiquantitative, b...

Resilient plant monitoring systems are sensor networks that degrade gracefully under malicious attacks on their sensors, causing them to project misleading information. This paper develops techniques to ensure resiliency and illustrates their application using a power plant. Specific techniques developed are: active data quality acquisition, process variable and plant condition assessments, sen...

Varga L. (2008): Hercinothrips femoralis (Reuter, 1891) – a new pest thrips (Thysanoptera: Panchaetothripinae) in Slovakia. Plant Protect Sci., 44: 114–118. Monitoring of pest species in plant production and extended trade on ornamental plant material, including precise identification, are the main goals of modern plant protection. As a result, a new species of phytophagous thrips – Hercinothri...

1 Supported by the Natural Science Fund Contract No. 69873007. Abstract In the monitoring system of power plant, the method of gathering real time data of sensors is often adopted. It not only increases the communication burden of monitoring system but also results in erroneous transmitting due to worse electromagnetism environment. For overcomring these shortcomings, we adopt a new approach --...

Agricultural pesticides when properly used can be highly effective for protection of plant and animal health. When misused, the environment as well as the agricultural community suffers. Because of the sporadic and often devastating occurrence of plant diseases and because of the development of very effective protectanttype pesticides, these are often used when the pathogen or conditions for in...

In production plants, monitoring and maintaining industrial processes and emergency shutdowns are not straightforward tasks due to the large number of events and alarms which are triggered during the plant shutdown process. It is also vitally important to provide decision support to stakeholders for efficient and effective monitoring and maintenance of production process. This paper presents a ...

We review existing machine condition monitoring techniques and industrial automation for plant-wide condition monitoring of rotating electrical machines. Cost and complexity of a condition monitoring system increase with the number of measurements, so extensive condition monitoring is currently mainly restricted to the situations where the consequences of poor availability, yield or quality are...
