    Our new article entitled "A Self-Learning Dynamic Path Planning Method for Evacuation in Large Public Buildings Based on Neural Networks" has been published online in "Neurocomputing". This study is one of a series of achievements in the application of machine learning technology in civil engineering. Evacuation path planning is of significant importance to safely and efficiently evacuate occupants inside public buildings. How to promote the personnel to complete evacuation in rapid, safe and sequential situation is an appreciable issue during design and operation & maintenance phrase. This study proposed the training according to a real large public building and then the approach managed to provide rapid and feasible evacuation guidance for both occupants to escape in multiple scenarios and managers to design the evacuation strategy.

    Langtao Wu successfully passed his undergraduate graduation defense in the Department of Civil Engineering of Tsinghua University. His research topic is "Data Automatic Acquisition on the Knowledge of MEP". The research tries to acquire the basic data of MEP knowledge mapping by the technologies of knowledge engineering and natural language processing to identify and extract the relationships of the entitits by collecting language materials. Then a web-based visualization tool was developed to vividly show the automated generated knowledge. The presentation file with voice has been added to "Resources" section.

    Our new article entitled "Automatically Generating a MEP Logic Chain from Building Information Models with Identification Rules" has been published in Applied Sciences. It is a free access article. The research achievement is one of the BIM innovative applications to MEP projects. The paper proposed an approach to integrate the geometrical topological information and the definitions for logic relations of recognition rules of BIM models, so that it can realize the automatic recognition and extension for logic relations of MEP. Such information is of significant importance to assist MEP projects during its operation phrase.

    Yaqi Xiao, the sixth master student under my supervision, has successfully passed his thesis defense in the Department of Civil Engineering of Tsinghua University. His master degree thesis entitle "Research on Search and Analysis of MEP Operation and Maintenance Information Based on Domain Ontology" has established the MEP knowledge mapping method based on MEP ontology. The proposed method searches the associated relationship and the logical relation of MEP based on domain knowledge. Finally, the method by eatablishing the monitoring information model for MEP, can search and analyze the KPI on building energy consumption.
