summary	As a new paradigm for construction in the ubiquitous era, IT Technology like RFID is an emerging issue in the building industry. For the purpose of RFID technology application in the building industry, this research suggests the Information Lifecycle Management using RFID technology in apartment building project and deals with the context-aware scenario for RFID technology application. The final objective of the research intends to develop the RFID application for the construction industry. From the tagging nodes at the material manufacture stage to the reading nodes at the end stage of the construction process, the flow of the RFID information deals with the synthetic application connecting physical construction material with electronic RFID information for the management. Furthermore, we suggest how to systematize, distribute and manage the construction material with the Information Lifecycle Management.

title	Strength Guided Motion
source	Computer Graphics. ACM, August, 1990. vol. 24: pp. 253-262 : ill. includes bibliography
summary	A methodology and algorithm are presented that generate motion imitating the way humans complete a lifting task under various loading conditions. The path taken depends on 'natural' parameters: the figure geometry, the given load, the final destination, and especially, the strength model of the agent. Additional user controllable parameters of the motion are the comfort of the action and the perceived exertion of the agent. The algorithm uses this information to incrementally compute a motion path of the end-effector moving the load. It is therefore instantaneously adaptable to changing force, loading, and strength conditions. Various strategies are used to model human behavior that compute the driving torques as the situation changes. The algorithm runs in near-real time and offers an agent-dependent toolkit for fast path prediction. Example are presented for various tasks

title	A fuzzy navigation system for mobile construction robots
source	Automation in Construction 6 (2) (1997) pp. 97-107
summary	Fuzzy navigation systems control a robot by implementing a fuzzy logic controller (FLC). Fuzzy navigation systems are simpler to implement than other navigation systems because they can handle infinite navigation situations with a finite set of rules. Existing fuzzy navigation systems for path finding in an unknown environment tend to find the shortest path in convex obstacle fields, but fail when obstacles are concave or placed continuously in certain configurations. This paper presents a fuzzy navigation system that can escape from concave and maze-like obstacle fields in an unknown environment. The system combines a tangent algorithm for path planning with sets of linguistic fuzzy control rules. In particular, we introduce the control rules for a Tracking mode of the FLC and improvements to the commonly used, intuitively reasonable tangent algorithm.

title	Automatic Finite- Element Mesh Generation from Geometric Models : A Point Based Approach
source	ACM Transactions on Graphics. October, 1984. vol. 3: pp. 287-311 : ill. includes bibliography
summary	A novel algorithm for automatic finite-element mesh generation is described. It uses constructive solid geometry to provide the geometric data for the object to be meshed. The geometric definition of the object and a value for the required mesh density are the only inputs. The method consists of two stages: point generation and mesh construction over the points. It has been implemented in two dimensions and is capable of generating predominantly 'good' quadrilateral elements. Triangular elements are only created in circumstances under which quadrilateral elements are not feasible

source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	About the glocal very much has been said by Michael Porter . According to this author, in some countries there is a competitive advantage, in some industry . It is explained by a « diamond » with four facets : competition and rivalry inside the country, factors endowment, demand, related industries (providers, firms selling components etc … ) . The competitive advantage appears when the facets are efficient, and stimulating one another, in a country. Then the firms of this country invest abroad, to benefit from thecompetitive advantage, grabing market shares and making profits . The country itself is the place of the competitive advantage . Theinternational market is the place of the challenge, where the result of the competition appears .

summary	This essay is related to the research project "The immersive experience in 360°: investigation, representation and digital immersion in the city of Rio de Janeiro in the 19th and 20th centuries", developed at PROURB in FAU-UFRJ, Rio de Janeiro/Brazil. This work will investigate the Panorama of Rio de Janeiro looking for memories and historical truths in its context: Which part represents a historical point of view? Which part is invention? How were the city and its landscape represented on the canvas? As the most well-known Rio de Janeiro's panorama, which project was idealized by the Brazilian painter Victor Meirelles de Lima (1832-1903) and the Belgian photo-painter Henri Charles Langerock (1830-1915), it was exhibited in Brussels 1888, Paris 1889, and Rio de Janeiro 1891-1896, with great recognition in all these cities. This paper will explore this Panorama, its initial studies, its landscape and the architecture depicted, newspapers descriptions of its exhibitions, and mainly, distinguishing among memories, historical truths and verisimilitudes. In order to achieve these objectives, digital and analogical systems of representations, sketches and computer graphics techniques, specially, tridimensional models will be developed and applied.

summary	Since the great popularity of smartphones and tablets, many applications have been developed to create digital panoramas. However, its focus is turned for the seamless of the pictures and not what we can explore and understand of its different subjects. This article intends to investigate the use of a new concept of an app for digital panoramas. We assume that Panoramapp! can broaden the understanding the history of the cities by its panoramas and panoramic views, an alternative way to develop an iconographic hyper document of the central area of the city of Rio de Janeiro.

summary	This article intends to investigate the meaning of Digital Panoramas as a tool to develop an alternative reading of the urban centralities in the city of Rio de Janeiro. We assume that Digital Panorama can bring significant contributions to urban research, in three different historical layers: at the beginning of 20th century; during the 20-40’s decades, and in the current days. The strength of panoramas in urban study is particularly enhanced by interactivity. This paper aims to demonstrate new possibilities in the association of panorama’s space recognition characteristic for historical study in urban centralities.

summary	Cities are seen as open platforms, in which citizens should be able to access information and propose, discuss and modify public policies without having to go through institutional and technocratic control. Systems based on collaborative platforms, such as Linux and Waze, are studied as experiences where user participation creates solutions that no centralized institutions are able to achieve, and looked at for references to build and manage platforms on which city planning could be based.

summary	Computer visualizations of planned built environment and infrastructures are increasingly used as a basis for democratic decisions when the impact of the projects is of wide-ranging interests and influence. It is of great importance for the democratic process that all aspects of the material in a project can be trusted as a basis for discussion and decisions among politicians and citizens. This paper describes the objective aspects of the quality of data in the information basis for 3D visualizations and it calculates the precision that can be achieved by the known methods of 3D-CAD visualization. Furthermore, the paper suggests a model that can secure sufficient quality in future visualization work processes by accumulating documentation for both the factual basic data and information that carry the aim and meaning of the message and make this information accessible through the visualization.

summary	The study analyzes three basic visual aspects of light (Spatial distribution of brightness, shadows and color of light) in their ability to communicate temporal information by modeling two specific scenarios using different lighting simulation software (DIALux and Relux). The results confirm the potentiality of natural light to assess temporal disorientation in indoor environments. At the same time, the study proposes new opportunities for improving natural light representation in the simulation field.

summary	Fictions for virtual reality are mostly conceived either in an entirely virtual environment or in a real environment with very little transformation. It is infinitely rare to find examples of sets designed and built specifically for a 360° experience. Building, rather than remaining purely virtual, raises complex questions about the organization of a "space to play" and therefore how to produce a narrative for immersion and create a 360° film grammar.We thus have created a first 360° set for the famous director Marc Caro, for whom the question of off-screen raised a very complex technical problem regarding lighting, visual effects, staging, blocking and acting. In this contribution we will show how this was solved and why the definition of a 360° narrative grammar is crucial. These are important intricacies that place the user-spectator in the optimal conditions to appreciate the experience.

title	Data mining for tunnel support stability: neural network approach
source	Automation in Construction 10 (4) (2001) pp. 429-441
summary	This paper presents a data mining approach to the prediction of tunnel support stability using artificial neural networks (ANN). The case data of a railway tunnel recently finished in Taiwan were used to establish the model. The main rock type was sedimentary rock. Rock mechanical and construction-related parameters with significant influences on support stability were filtered to train and test the ANN. Validation was also performed to show that the ANN outperformed the discriminant analysis and the multiple non-linear regression method in predicting tunnel support stability status.

title	Resource leveling in construction by genetic algorithm-based optimization and its decision support system application
source	Automation in Construction 10 (1) (2000) pp. 27-41
summary	Traditional analytical and heuristic approaches are inefficient and inflexible when solving construction resource leveling problems. A computational optimization technique, genetic algorithms (GAs), was employed in this study to overcome drawbacks of traditional construction resource leveling algorithms. The proposed algorithm can effectively provide the optimal or near-optimal combination of multiple construction resources, as well as starting and finishing dates of activities subjected to the objective of resource leveling. Furthermore, a prototype of a decision support system (DSS) for construction resource leveling was also developed. Construction planners can interact with the system to carry out ad hoc analysis through "what-if" queries.

summary	Browser-based platforms (Google Docs or Minecraft) have instigated the value of collaborative environments. Browser-based modelling point out a future for the AEC industry. Yet at present no literature review nor a taxonomy of browser-based modelling platforms exist. A key outcome of a unique taxonomy framework of existing BMA characteristics reveals that current BMAs do not take full advantage of the web's unique capabilities such as centralising data across multiple tools within an 'ecosystem'. Consequently, this taxonomy has productively guided the development of Redback BIM, a proof-of-concept BMA that enables the coordination of BIM data in a collaborative online context. Redback BIM further demonstrates how, through establishing a universal data-type, a diverse range of scripts can be consolidated together in an online platform to enable greater accessibility for a range of AEC professionals towards improved project communication and efficiency.
