GRADIENT is a research project within the ESPRIT programme. The project aims to prove design principles, for the development of advanced interface systems for process control. The primary result is a graphical dialogue environment in which knowledge-based systems and dialogue design combine to provide advanced information processing for complex process control domains. From its inception, the run-time GRADIENT system was conceived to embody a software architecture derived from the philosophy of user interface management systems (UIMS). Within GRADIENT two monitoring and response systems are assigned, one to the process, and another to the operator. The former, a specialised expert system module, called QRES, attacks the problem of intelligent alarm handling. In his actions on the process, the operator is monitored by a plan-recognition system, called RESQ. This knowledge-based system attempts to interpret the operators' likely control objectives, given the process state and his recent activity. Behind these two monitoring advisory systems, GRADIENT provides a support system with more extensive knowledge of the process plant.< >

BBN Systems and Technologies in Edinburgh is engaged in a research and development programme investigating intelligent process monitoring (IPM), aimed at producing a practical online advisory system for the process industries. In this project BBN is capitalising on its expertise in the fields of data acquisition and analysis, expert systems, computer systems, control and man-machine interfaces. The introduction of online IPM systems will assist operators by abstracting alarm information, isolating potential faults, aiding fault diagnosis and proving information to help the operator make decisions that affect future plant performance and safety. BBN is developing an IPM system based around an existing signal processing and graphics display package and a commercially available expert system shell. To these elements BBN have added software for data acquisition, a structure for controlling interprocess communications, and real-time extensions for the expert system.< >

As the volume of data collected by an increasing number of satellites escalates, it has become of paramount importance that methods of coping with and making best use of this information are developed. Current trends are moving towards automatic and knowledge-based analysis systems particularly for monitoring applications where the same kinds of interpretation task must be repeated many times. The MuSIP project, part funded by the European ESPRIT programme for research information, aims to develop a software demonstrator for the automatic fusion and analysis of multisource data. The project recognises this need across all computer vision applications and so will test the demonstrator on two dissimilar applications, one in the field of remote sensing and one in the field of medical image analysis. The target remote sensing application is the monitoring of forestry using a dataset of radar and optical imagery, map and ground data. This paper introduces the modules that comprise the demonstrator that is: a supervisor with its associated knowledge bases, algorithms and the databases. Attention is focussed in particular on the role of knowledge bases and the methods of data fusion.< >

Apparatus has been developed for the acquisition of 3D X-ray commuted tomography images in cone-beam geometry. The equipment consists of a microfocal X-ray source operating at photon energies of up to 30 kVp with a focal spot size of 10 mu m, a computer-controlled stage for rotating the object, a 2D multi-wire gas proportional X-ray counter and a microcomputer to controlimage acquisition. Projection data were generated by rotating the object in discrete steps around a single axis until of the order of 100 2D projection images of the object were collected. The projection images were transferred to a VAX 11/750 computer for subsequent 3D reconstruction using a convolution and back-projection algorithm. The reconstructed data were displayed as transaxial, sagittal and coronal planes through the object. The specification of the acquisition hardware is discussed and some projection images together with the corresponding 3D reconstruction of the object are shown with pixel sizes smaller than 100 mu m.< >

In urban households such as houses and condominiums in the city, there are a lot of cases where people waste huge amount of clean water in irrigating plants. Siling Labuyo is a common spice in the Philippines and apparently, birds are one of the few who can eat Siling Labuyo Peppers in urban areas. This paper tackles the use of a Raspberry Pi model 3B+ to control an automated irrigation system with a bird deterrent system. The irrigation system is based on evapotranspiration referenced by the Penman-Monteith equation. It estimates the net evapotranspiration using solar radiation, temperature, humidity, and wind speed as parameters. It aims to determine the significance of the system when it comes to the total number of fruits produced per plant in a span of 6 weeks. imageprocessing was used for the bird detection, Opencv was used for object detection, using a trained Haar cascade model in order to detect birds. While a rotating red light was used for the bird deterrence. The Raspberry Pi controls the water flow for the irrigation system and the switching of the light for the bird deterrent system. This paper concludes that: the ET-based irrigation system does not affect the number of fruits produced by the plant as compared to the usage of the traditional irrigation system, the ET-based irrigation system saved 15931.7238 mL of water compared to the traditional irrigation system, and the rotating red light was an effective way to deter the Eurasian tree sparrow "Maya" birds.
