The present paper considers constructing associative models for non-linear processes and a condition of stability of the process in a predicted time instant. A methodology of selecting enough quantity of input vectors to construct process models based on the associative search is considered. As well, an example of constructing models on the basis of the associative search and meeting the condition...
Building automation systems control many aspects of today's buildings - lightning control, air condition, shading, access control, and surveillance, just to name a few. This diversity and the diversity of related technologies and protocols entails that the extension or integration of building automation systems requires a major effort. To address these challenges, the ITEA3 Building as a Service (BaaS)...
In recent years, photovoltaic (PV) power generation is developing rapidly on account of its environment friendliness. However, the PV devices between different manufacturers could hardly interoperate because of different model and protocols they applied. This paper built the information model for PV power generation based on IEC61850, which is more normative and convenient for PV plant configuring...
The design and development of aerospace product is a collaborative multi-discipline project. The integrated and consistent information modeling of all the information, models, documents and other product data generated during design and development is critical to success. An integrated information model, defined as EDPS (Engineering Digital Prototyping for Satellite) is proposed. Aiming at modeling...
In implementing good financial management and to be able to maintain the result of the audit report that Padjadjaran University (Unpad) has financial statement with state fair without exception (Wajar Tanpa Pengecualian (WTP)), Unpad should be able to improve the management of financial information to produce quality information. To produce this quality information Unpad should be integrated the exisisting...
Large and various amounts of context data related to a user's environment are available from different domains including mobile devices, smarthomes, wearable sensors, and social networking services. These context domains are interconnected and the context data from them can be shared thanks to mobile, pervasive, convergent, and ubiquitous technologies. We can provide user-centric context-aware services...
Companies with established and reliable control systems are often confronted with the question of how to benefit from upcoming innovations in science and practice without removing or extensively changing their systems. One of the currently often discussed innovations is the new standard OPC Unified Architecture (OPC UA). OPC UA provides an improved data transport and a semantically rich information...
Nowadays, wind energy is one of the most recognized renewable energy sources. Onshore wind farms have been built in many countries, such as Denmark, Norway, UK, Italy, Brazil and the US. To utilize the more stable wind resources, wind farms have moved off the shore, first to shallow waters near shore and now extending to deeper waters and far off the shore. Deep-water offshore solutions will give...
The execution of workflow oriented applications for eScience should be based on efficient solutions for available resource monitoring and scheduling by revising the allocation solution at the task level based on requirements of subsequent tasks. The PEGAF project aims at providing a platform for workflow oriented applications development and execution, implementing adaptive scheduling strategies....
The district collaborative design is an advanced design organization mode. The problem of definition and expression of correlation in collaborative design is aimed. The organization characteristics are analyzed based on district collaborative design space. The connection relationship acyclic graph which includes connection semantics is achieved and the relationship specialty and connection mode are...
In this paper, we discuss information model of IEC 61850 protocol. We give the prototype design of information model of IEC 61850 and study record accessing times. We suggest use of real time main memory database model for IEC 61850. We also use TLSF memory allocator for assigning memory to records in IEC 61850 prototype. We suggest a back up scheme for database for fast crash recovery. Finally we...
Data exchange, safety and security are required in many measurement and control systems in which programmable logic controllers are used in recent days. In this paper, we will describe the IEC 61131–3 software model at the first, and then introduce the method to translate this model to the information model of OPC UA. We will also mention that the translation between the models will be based on the...
The information integration model which includes all the knowledge in the manufacture phase of produce is very significant for produce manufacture. In the study, the construction of information integration model based on the design knowledge of product is presented to gain manufacture information completely and fast. Firstly, the information integration model is introduced, and the transformation...
Due to the problem of complex relation between different data types existing in information model of fault tree diagnosis, the modeling method for information model of fault tree diagnosis based on UML is proposed. Firstly, the requirement of integrated diagnosis and AI-ESTATE to information in test and diagnostic environment and the shortage of information model of fault tree diagnosis is analyzed...
A product information model based on STEP, which mainly contains five parts such as general information model, structure information model, shape description model, physical feature model and management information model, has been studied. Its description method and exchange mode of neutral file are also researched. The model has the features of integrality, consistency, variety, flexibility and neutral...
Based on the background of analysing "expert power" in data fusion technology, we put forward the problem of "expert power" fusion to be solved in real estate appraisal. By determining the fusion criteria and building the information model of reliability, we establish the appraised algorithm of information fusion. This method can improve the accuracy of evaluation, reduce the error...
According to the deformation trend of the plasmodium, the paper utilizes the concept of equal dimension and new information in grey theory to train BP network, sets up equal-dimension and new information model that can fully reflect the law of deformation, and carries on real deformation prediction with this model. Meanwhile, the text utilizes GM (1,1) model of grey theory to predict the plasmodium...
Information model has been developed to store data about the reachability graph. The developed model uses data structures based on double-ended lists and XML-format enabling possibility of graph structure modification and integration with other subsystems of information technologies of micromechanical system analysis and synthesis.
Scientific digital libraries serve complex and evolving research communities. Justifications for the development of scientific digital libraries include the desire to preserve science data and the promises of information interconnectedness, correlative science, and system interoperability. Shared ontologies are fundamental to fulfilling these promises. We present a tool framework, a set of principles,...
Most service and network management applications are developed to use vendor- and device-specific management data. These data are produced from different languages, and hence can have different representations of the same concept. We define a novel knowledge representation and mapping mechanism that uses ontological concepts and relations to generate a formal description for the Directory Enabled...
