Issues such as energy shortage and global warming become prominent. Meanwhile, the rapid growth of the load makes the grid pay more attention to demand side. Demand response (DR) is an effective tool to change the shape of the load. Usually buildings consume much energy, and also have great DR capability. It is crucial to assess the DR capability of buildings, which is a tough task because the building...
Engineering design is a complex activity for students to undertake and for instructors to assess. This research uses large learner data sets collected through automatic, unobtrusive logging of student actions in a CAD platform to address this difficulty in observing design behavior. We used a computer-aided design software that captured student design activities to investigate patterns of student...
In this paper, we review state-of-the-art research into automated construction by autonomous mobile robots. Today, space research agencies seek to build infrastructure without human intervention; and construction companies look to robots as having the potential to achieve improvements in construction quality, efficiency, and safety, not to mention flexibility in architectural design. This paper addresses...
Unmanned aerial vehicles (UAVs) such as multicopters are expected to be used for inspection of aged infrastructure or for searching damaged buildings in the event of a disaster. However, in a confined space in such environments, UAVs suffer a high risk of falling as a result of contact with an obstacle.
In this study the case of the energy consumption profile of the Aristotle University of Thessaloniki, in Greece, is presented and statistically analyzed by clustering methods on the basis of seasonal daily load curves and load shape factors, using data from real-time measurements. The results indicate that the categorization of active power demand in university buildings is an extremely useful tool...
Distributed teams of agents can provide robust solutions to many problems of interest, and allowing a human to influence and manage those agents can extend the range of problems that can be solved while improving the team's efficiency. Within this context, it is interesting to develop methods for interaction that are intuitive and that utilize haptic interaction so that the human manager need not...
Comparative analysis of the subarray factor shape and subarray architecture complexity is carried out for an approach proposed recently to building linear arrays of overlapped subarrays for limited field of view based on using beam-forming matrices. The comparisons are performed with other array architectures including arrays with the known chess board network. The issue of application of the approach...
The research deals with integration of photobiological treatment facilities with building's architectural shell and issues of using natural light to grow algae. The goal is optimizing the shape of the architectural shell of building with algae photobioreactor units. Using microalgae photobioreactors can solve multiple tasks: getting a third-generation biofuels, carbon dioxide recycling, wastewater...
This study aims to define the depths, size, shape, and lateral extents of walls of the foundation of the Hagios Georgios Church by using ground-penetrating radar (GPR) as only some of its surrounding walls are currently on the surface nowadays. According to the literature, some restoration should be performed on its walls to prevent the complete demolishment of the extant walls of the church. Similar...
In the recent past there is increased interest in detection and extraction of buildings using object based approaches on given high to very high resolution imagery. In this paper, we introduce a new unsupervised approach to detect buildings from the very high resolution (VHR) multispectral satellite image. Independent component analysis (ICA) followed by Otsu thresholding is used for extraction of...
The Santa Creu and Sant Pau hospital is a monumental ensemble built in Barcelona between 1901 and 1930 on the site where six small medieval hospitals were founded in 1401. It is a complex of buildings which represent the art nouveau architecture in Barcelona. It was declared World Heritage site by the UNESCO in 1997. In the previous eight decades of clinical activity, modernist buildings have experienced...
We develop an approach for detection of ruins of livestock enclosures in alpine areas captured by high-resolution remotely sensed images. These structures are usually of approximately rectangular shape and appear in images as faint fragmented contours in complex background. We address this problem by introducing a new rectangularity feature that quantifies the degree of alignment of an optimal subset...
Building damage information is an important basis of earthquake disaster loss assessment, it is also one of judgement index of earthquake intensity. In the process of using remote sensing image for earthquake disaster information acquisition and earthquake emergency rescue, building damage information extraction technique is the key to get accurate disaster information. In this paper, based on the...
After a terrible disaster such as an earthquake or a nuclear accident, finding victims and isolating them from hazards are usually the first priorities for rescuers. As the security of rescuers and the stabilization of the environment are critical components of the first rescue phase, we assume that robots could be used to secure the environment by performing construction tasks, to stabilize large...
New elevation models from the Czech Republic are produced using airborne laser scanning. These new elevation models achieve much higher accuracy than previous models whose accuracy is expressed in meters. Declared accuracy was subjected to verification in five selected locations. Despite some problems with accuracy, especially in areas of significant microrelief shapes, these models comply the declared...
A global scheme combining intensity and stereo data to improve urban landscapes modeling from aerial or satellite stereopairs is presented. Both intensity and stereo data are used for building detection, recognition and scene reconstruction. Grey-level intensity data features are used to improve the quality of depth maps stereo processing and depth maps features are used to improve monocular analysis...
An increasing number of photos in Internet photo collections comes with watermarks, timestamps, or frames (in the following called WTFs) embedded in the image content. In image retrieval, such WTFs often cause false-positive matches. In image clustering, these false-positive matches can cause clusters of different buildings to be joined into one. This harms applications like landmark recognition or...
This paper presents the results of an ongoing research on the survey of vaulted structures of important Italian monumental buildings belonging to UNESCO World Heritage Sites (Ravenna, Rome and Florence). The three case studies deal with various problems of documentation and representation of vaults and domes from different points of view: the first example is concerned with the conversion of apparent...
People detection is a crucial component in many applications such as stadium or building evacuation and marketing analysis. It gives important information on the current number of people in a building or a room. In this work, we propose an algorithm for a real-time people detection system from a sequence of depth images acquired with a vertical depth sensor. The processing pipeline includes a pre-processing...
While the growing demand for new building models contained in virtual worlds, games, and movies, makes the easy and fast creation of modifiable models more and more important, 3D modeling of buildings can be a tedious task due to their sometimes complex geometry. For historic buildings, especially the roofs can be challenging. We present a new method of combining simple building solids to form more...
