Digital forensic investigation process is about identifying and tracing the cause of the incident, whereby traceability is very important process during the investigation by searching for the evidence. However, the traceability model of digital forensic investigation process is enhanced based on scenario with proven literature and justification.
There are some quality and safety problems for material management in the construction project. Based on material batch mapping, we design a traceable model for material quality in this paper. in the model we define the traceable object (TOB). Based on traceable batch record and coding step by step, the model defines the batch quality feature (BOF). Based on the BOF, the model associates material...
Modern process system can be regarded as multi-medium interacted heterogeneous networks comprised of material transportation, power supply and control information exchange, in which substance like material, energy and information coexist and interact. Thus fault diagnosis and safety analysis for complex process system based on homogeneous network theory should be improved to hold multi-medium interacted...
Service safety appraisement of engineering materials is important for public security. This paper describes a data sharing platform for safety appraisement based on material scientific data. The data sharing platform consists of three layers: data collection layer, data organization layer and data application layer. The data collection layer integrates the methods, standards and data, including physical...
The construction industry has been facing a paradigm shift to (i) increase; productivity, efficiency, infrastructure value, quality and sustainability, (ii) reduce; lifecycle costs, lead times and duplications, via effective collaboration and communication of stakeholders in construction projects. Digital construction is a political initiative to address low productivity in the sector. This seeks...
For application researches of the detection for the gas signal source, a method for orientation estimation of the gas signal source in the two-dimensional space and its algorithm are presented in the paper. In the method, a mode of dual-line gas sensor array is applied to sample the signals of the gas concentration in real time, and the time delay estimation, an approach of the signal processing,...
