    Learning Material-Aware Local Descriptors for 3D Shapes

    Full text link
    Material understanding is critical for design, geometric modeling, and analysis of functional objects. We enable material-aware 3D shape analysis by employing a projective convolutional neural network architecture to learn material- aware descriptors from view-based representations of 3D points for point-wise material classification or material- aware retrieval. Unfortunately, only a small fraction of shapes in 3D repositories are labeled with physical mate- rials, posing a challenge for learning methods. To address this challenge, we crowdsource a dataset of 3080 3D shapes with part-wise material labels. We focus on furniture models which exhibit interesting structure and material variabil- ity. In addition, we also contribute a high-quality expert- labeled benchmark of 115 shapes from Herman-Miller and IKEA for evaluation. We further apply a mesh-aware con- ditional random field, which incorporates rotational and reflective symmetries, to smooth our local material predic- tions across neighboring surface patches. We demonstrate the effectiveness of our learned descriptors for automatic texturing, material-aware retrieval, and physical simulation. The dataset and code will be publicly available.Comment: 3DV 201

    The report summarizes the analysis of the existing fire protection features and systems installed in the Construction Innovation Center at California Polytechnic State University, San Luis Obispo. The center is divided into three individual buildings (Buildings A, B and C) and are connected at each floor by an exterior balcony. The analysis includes two different approaches. A prescriptive analysis approach has been used to examine if the installed fire protection features and systems compliance with the latest edition of the codes and standards in California. This approach includes an evaluation of the fire structure protection, means of egress, fire alarm & communication, and fire-suppression system of the center. A performance–based analysis approach has also been used to assess whether the building occupants will egress the center before conditions become untenable. Fire Dynamics Simulator and Pathfinder, two computer software programs, have been used to determine the available and required safe egress time. A fire scenario has been selected for Buildings A and B to assess its tenability conditions. Building C was not selected as part of the tenability analysis due to time constraint and low existing ignition sources

    Analysis of the Active and Passive Fire Protection Systems in the Government Building, Depok City, Indonesia

    In many countries, fires in buildings have resulted in loss of many lives, damaged properties and financial losses. In Indonesia, there has been increasing reported cases of fire occurring in public buildings over the years. This study aimed to assess the risks of fire and fire protection systems in government office buildings in Depok, Indonesia. A descriptive study was conducted using triangulation approaches on government buildings in Depok from March to April 2016. Primary and secondary data was collected using observation, unstructured interview of key informants and documentation review. Descriptive and comparative data analyses were conducted in the study. The key problems identified in the fire protections systems in the building were heat detector installed near the air conditioner, damaged to the alarm circuits, sprinklers mounted at a distance exceeding the applicable regulations, lack of complete hydrants, and a lack of fireproof doors and windows. The gap between standard/regulation and the condition of fire protection systems in the building are based on a lack of knowledge about the essence of the building management system and standard fire protection. There are minimal active and passive fire protection systems in office buildings, and few components are not adequately practiced in accordance with international and local standards and regulations. For safe systemof work, the entire fire protection system need to be tested periodically so that the system would work well in case of an emergency. It is important to conduct regular inspections and maintenance of the fire protection systems specifically in office buildings.
