The academic debate on transparency has experienced a boom in recent decades. A review of the scientific literature allows us to identify two key moments discussion digital transparency: declaration Barack Obama’s Memorandum and open government 2009 Cambridge Analytica scandal 2018. first was linked groundswell enthusiasm for concept transparency, with promise that it would boost accountability...

In this paper, we present an original environment, the Distributed Collaborative Design Studio (DCDS) which allows multimodal real-time remote exchanges, and which aims at re-creating remotely the conditions of co-present meetings. This environment associates a videoconference tool (supporting verbal and non-verbal communication) and an original realtime shared digital hand-drawn sketches syste...

This paper describes how to model and evaluate a next generation communication system in combined multi-domain simulation environments. Because the communication system consists of complex analog and digital components, it is vital to model accurately in order to understand the behavior of the system. The multi-antenna system architectures, advanced modem technology and millimeter wave (mm-wave...

Digital Clay is an NSF funded project for human machine communication through a tangible haptic surface actuated using fluid power. Digital Clay’s hardware can be divided into three subsystems: massive-integrated actuator-sensor array, fluidic driving system, and control system. Focus of this paper is the control of some of the special mechanisms of Digital Clay. Specifically, the Fluid Matrix ...

Campus Card is an important part in the digital campus life. However, due to the problems of current network design, in the course of card using, the signal channels are seized by a large number of communication tags, which leads to the phenomena of blocked communication process and unsmooth communication. In order to solve this problem, the communication module of card system has been optimize...

BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...

Exact expressions for bit-error probability (BEP) for coherent square detection of uncoded and coded M-ary quadrature amplitude modulation (MQAM) using an array of antennas with maximal ratio combining (MRC) in a flat fading channel interference limited system in a Nakagami-m fading environment is derived. The analysis assumes an arbitrary number of independent and identically distributed Nakag...

We have developed a hardware-assisted interprocess communication (IPC) that enables the design of a digital control system using component-based software on embedded microcontrollers with limited resources. The realtime communication mechanism allows processes to exchange data in a predictable and timely manner, with minimum overhead. The hardware assist is a modified direct memory access (DMA)...
