As-is three-dimensional (3D) models of indoor environments are paramount importance for a variety applications such as navigation assistance and emergency response. Whereas manual reconstruction 3D is time-consuming task, methods automatic or semiautomatic can achieve significant reduction the time labor required modeling. This paper proposes new shape grammar approach efficient generation from point clouds. The derives complex by using simple primitive iterative application rules governed...

Automated reconstruction of Building Information Models (BIMs) from point clouds has been an intensive and challenging research topic for decades. Traditionally, 3D models indoor environments are reconstructed purely by data-driven methods, which susceptible to erroneous incomplete data. Procedural-based methods such as the shape grammar more robust uncertainty incompleteness data they exploit regularity repetition structural elements architectural design principles in reconstruction....

Gestational diabetes mellitus (GDM), which complicates up to 20% of all pregnancies, is associated with low-grade maternal inflammation and peripheral insulin resistance. Sterile infection are key mediators this Resveratrol, a stilbene-type phytophenol, has been implicated exert beneficial properties including potent anti-inflammatory antidiabetic effects in non-pregnant humans experimental animal models GDM. However, studies showing the resveratrol on resistance GDM human tissues have...

Abstract. Existing indoor mapping systems have limitations in terms of time efficiency and flexibility complex environments. While backpack handheld are more flexible can be used for multi-storey buildings, some application scenarios, e.g. emergency response, a light-weight eyewear or head-mounted system has practical advantages. In this paper, we investigate the spatial capability Microsoft Hololens mixed reality 3D large We provide geometric evaluation mesh data captured by local...

Preterm birth is the largest single cause of neonatal death and morbidity. By activating cytokine- Toll-like receptor (TLR)-signaling pathways, infection and/or inflammation are strongly associated with preterm delivery. Interferon regulatory factor-1 (IRF1) an important regulator inflammatory response. The aims this study were to establish effect 1) labor on IRF1 expression in human fetal membranes myometrium, 2) prolabor mediators activity, 3) small interfering RNA mediators. was higher...

This paper reports the results of ISPRS benchmark on indoor modelling. Reconstructed models submitted by 11 participating teams are evaluated a dataset comprising 6 point clouds representing environments different complexity. The evaluation is based measuring completeness, correctness, and accuracy reconstructed wall elements through comparison with manually generated reference models. show that performance methods varies across datasets, but generally reconstruction achieve better for...

Abstract. 3D models of indoor environments are essential for many application domains such as navigation guidance, emergency management and a range location-based services. The principal components defined in different BIM standards contain not only building elements, floors, walls doors, but also navigable spaces their topological relations, which path planning navigation. We present an approach to automatically reconstruct relations between from point clouds. Three types namely...

Abstract. Building Information Models (BIMs) are of paramount importance in lifecycle management buildings as they enable collaboration among various stakeholders at different phases a construction project, from planning to maintenance and operation. However, there is usually inconsistency between the as-is condition building its existing BIM, because BIMs generally not updated reflect changes environment. Monitoring during building’s keeping BIM up-to-date useful for variety applications....

Abstract. Despite recent progress in the development of methods for automated reconstruction indoor models, a comparative performance evaluation these is not available due to lack publicly benchmark datasets and common framework. The ISPRS Benchmark on Indoor Modelling an effort enable comparison benchmarking modelling by providing dataset comprehensive In this paper, we propose framework methods, discuss various quality aspects as well reconstructed models. We challenges quantitative models...

Abstract. Automated reconstruction of 3D interior models has recently been a topic intensive research due to its wide range applications in Architecture, Engineering, and Construction. However, generation the from LiDAR data and/or RGB-D is challenged by not only complexity building geometries, but also presence clutters inevitable defects input data. In this paper, we propose stochastic approach for automatic spaces point clouds, which applicable both Manhattan non-Manhattan world...

Abstract. Automated 3D reconstruction of indoor environments from point clouds has been a topic intensive research in recent years. Different methods developed for the generation models have achieved promising results on different case studies. However, comprehensive evaluation and comparison performance these not available. This paper presents preliminary ISPRS benchmark modelling, an initiative Working Group IV/5 to modelling using public dataset framework. The performances are compared...

Abstract This paper presents a nonlinear simulation method for composite framing systems constituted from concrete‐filled steel tubular columns (CFST) and beam systems. A force‐based fibre beam‐column element in OpenSees was adopted. capable of accurately capturing the local buckling confining effect concrete using modified stress‐strain relationships fibres. source code connection also developed to capture semi‐rigid behaviour beam‐to‐column connections buildings.
