The primary characteristic of an Ultra-Large-Scale (ULS) system is ultra-large size on any related dimension. A ULS system is generally considered as a system-of-systems with heterogeneous nodes and autonomous domains. As the size of a system-of-systems grows, and interoperability demand between sub-systems is increased, achieving more scalable and dynamic access control system becomes an im...

The Internet of Things (IoT) emerged to describe a network connected things on large scale offer services number applications in different environments and domains. Middleware is software that seeks facilitate the management communication all these things, providing necessary functionalities manage discover, compose services, perform communication. For this reason, several proposals for middlew...

Abstract This study analyses one of the most popular game engines and an audio middleware to reproduce sound according propagation physics. The analysis focuses on transmission path between source receiver. Even if there are several ready-to-use real-time auralization platforms software, engines' use with this aim is a recent area for acousticians. However, design needs limits their basic relea...

Abstract The emergence of the Internet Things has fueled a proliferation smart things in many fields, including cultural spaces. Context-awareness addresses production large volumes context by analyzing raw data and adding meaning to them. Middleware systems have emerged, which perform modelling reasoning, supporting context-aware applications. services provided such applications can be persona...

Purpose The Reflective Middleware for Acoustic Management (ReM-AM), based on the Cloud Learning Environments (AmICL), aims to improve interaction between users and agents in a Smart Environment (SE) using acoustic services, order consider unpredictable situations due sounds vibrations. middleware allows observing, analyzing, modifying interacting every state of SE from acoustics. This work deta...
