The ARQUIGRAFIA project: A Web Collaborative for Review Only Environment for Architecture and Urban Heritage Image

Purpose:This paper presents the ARQUIGRAFIA project,an open,public and nonprofit,continuous growth web collaborative environment dedicated to Brazilian architectural photographic images.Design/methodology/approach:The ARQUIGRAFIA project promotes the active and collaborative participation among its institutional users(GLAMs,NGOs,laboratories and research groups)and private users(students,professionals,professors,researchers),both can create an account and share their digitized iconographic collections in the same Web environment by uploading their files,indexing,georeferencing and assigning a Creative Commons license.Findings:The development of users interactions by means of semantic differentials impressions recording on visible plastic-spatial aspects of the architectures in synthetic infographics,as well as by the retrieval of images through an advanced system search based on those impressions parameters.By gamification means,the system often invites users to review images’in order to improve images’data accuracy.The pilot project named Open Air Museum that allows users to add audio descriptions to images in situ.An interface for users’digital curatorship will be soon available.Research limitations:The ARQUIGRAFIA’s multidisciplinary team gathering professorsresearchers,graduate and undergraduate students from the Architecture and Urbanism,Design,Information Science,Computer Science faculties of the University of S?o Paulo,demands continuous financial resources for grants,for contracting third party services,for the participation in scientific events in Brazil and abroad,and for equipment.Since 2016,significant budget cuts in the University of S?o Paulo own research funds and in Brazilian federal scientific agencies can compromise the continuity of this project.Practical implications:The open source template called+GRAFIA that can freely help other areas of knowledge to build their own visual Web collaborative environments.Originality/value:The collaborative nature of the ARQUIGRAFIA distinguishes it from institutional image databases on the internet,precisely because it involves a heterogeneous network of collaborators.

CONSTRUCTION OF INTEGRATED CAD TOOLS ENVIRONMENT TO SUPPORT CONCURRENT COLLABORATIVE DESIGN

A CAD tools environment is described to support concurrent collaborative design. The environment has four components: shared design representation, design process control, CAD tools, designer interface. Some related issues for the construction, such as form feature handling, constraint satisfaction, design process control, STEP based information integration, are discussed in more detail.

Virtual Reality Used in the Lighting System Management of a Building

The first component of a building implemented in a virtual prototype concerning the management of a building is a lighting system. It was applied in a study case. The interactive application allows the examination of the physical model, visualizing, for each element modeled in three-dimensions （3D） and linked to a database, the corresponding technical information concerned with the use of the material, calculated for different points in time during their life. The control of a lamp stock, the constant updating of lifetime information and the planning of periodical local inspections are attended on the prototype. This is an important mean of cooperation between collaborators involved in the building management.

An Orientation Update Message Filtering Algorithm in Collaborative Virtual Environments

Orientation update message filtering is an important issue in collaborativevirtual environments (CVEs). Dead-reckoning (DR) is a known effective mechanism for update messagefiltering. Yet, previous dead-reckoning techniques mainly focus on the update message filtering forpositions. The existing orientation dead-reckoning algorithms are based on fixed threshold values.The drawbacks of fixed thresholding for orientations (FTO) are discussed in this paper. We propose avariable thresholding for orientations (VTO) based on average recent angular velocity. The mainadvantage of the proposed VTO is the ability of balancing the number of state update messages andshift frequency of direction and speed of rotation.

Novel Architecture of Security Orchestration, Automation and Response in Internet of Blended Environment

New technologies that take advantage of the emergence of massive Internet of Things(IoT)and a hyper-connected network environment have rapidly increased in recent years.These technologies are used in diverse environments,such as smart factories,digital healthcare,and smart grids,with increased security concerns.We intend to operate Security Orchestration,Automation and Response(SOAR)in various environments through new concept definitions as the need to detect and respond automatically to rapidly increasing security incidents without the intervention of security personnel has emerged.To facilitate the understanding of the security concern involved in this newly emerging area,we offer the definition of Internet of Blended Environment(IoBE)where various convergence environments are interconnected and the data analyzed in automation.We define Blended Threat(BT)as a security threat that exploits security vulnerabilities through various attack surfaces in the IoBE.We propose a novel SOAR-CUBE architecture to respond to security incidents with minimal human intervention by automating the BT response process.The Security Orchestration,Automation,and Response(SOAR)part of our architecture is used to link heterogeneous security technologies and the threat intelligence function that collects threat data and performs a correlation analysis of the data.SOAR is operated under Collaborative Units of Blended Environment(CUBE)which facilitates dynamic exchanges of data according to the environment applied to the IoBE by distributing and deploying security technologies for each BT type and dynamically combining them according to the cyber kill chain stage to minimize the damage and respond efficiently to BT.

Geographic analysis-oriented Virtual Geographic Environment:Framework,structure and functions

Previous research on the Virtual Geographic Environment （VGE） has focused mainly on representation rather than geographic analysis. However, geographic analysis plays a significant role in modem geography. To address this issue, this paper systematically examines theories and implementing VGE techniques that support geographical analysis and simulation. Based on its framework, VGE can be divided into four subtypes. These are the data environment, modeling environment, expression environment, and collaborative environment. The functions and key techniques of each are examined, and some case studies are discussed. This study provides direction for necessary new developments of advanced VGE platforms.
