RATIONALE, AIMS AND OBJECTIVES Loss of situation awareness (SA) by health professionals during handover is a major threat to patient safety in perinatal care. SA refers to knowing what is going on around. Adequate handover communication and process may support situation assessment, a precursor of SA. This study describes current practices and opinions of perinatal handover to identify potential...

This paper focuses on the way in which small and medium-sized businesses Flanders adapted communication with their customers during economic lockdown March–May 2020. It documents, more specifically, how shops tried to maintain, re-establish, or even re-invent this two-month period. Based pictures of shop windows a Flemish city, we analyze (semi-)commercial messages that appeared setting analysi...

The relationship between modulation format and the performance of multi-channel digital back-propagation (MC-DBP) in ideal Nyquist-spaced optical communication systems is investigated. It is found that the nonlinear distortions behave independent of modulation format in the case of full-field DBP, in contrast to the cases of electronic dispersion compensation and partial-bandwidth DBP. It is sh...

The modulators are the essential demand of communication systems they are designed to scale back the channel distortion & to use in RF communication therefore several sort of carrier modulation techniques has been already projected consistent with channel properties and rate of the system. Modulation is that the method of causation knowledge signal over carrier signal to attenuate the noise or ...

This project is an implementation of an Ajax web application. AJAX is a new technology based on asynchronous communication between a client web browser and a back-end server, allowing web applications to request and receive data without ever reloading the page. A popular application that uses Ajax technology is Google Maps. The goal of this project is to develop an extension of Google Maps whic...

23.1 Abstract A brain-computer interface (BCI) is a closed-loop system with feedback as one important component. Dependent on the BCI application either to establish communication in patients with severe motor paralysis, to control neuroprosthesis, or to perform neurofeed-back, information is visually fed back to the user about success or failure of the intended act. One way to realize feedback...

This paper presents a new approach to equalization of communication channels using Artificial Neural Networks (ANNs). A novel method of training the ANNs using Tabu based Back Propagation (TBBP) Algorithm is described. The algorithm uses the Tabu Search (TS) to improve the performance of the equalizer as it searches for global minima which is many a time escaped while Back Propagation (BP) algo...

This paper describes an efficient implementation of the Viterbi decoding algorithm on the ZSP500 digital signal processor (DSP) core. It starts with an introduction to convolutional coding and Viterbi decoding as a method of forward error correction in communication systems. An introduction to the ZSP500 architecture is followed by a description of special instructions for performing the Trelli...

Emerging AI techniques will make possible new intelligent help features, such as ‘active help’ (interrupting the user when appropriate) and ‘back channel’ communication (allowing users to send a message to a help system). An investigation was conducted to determine whether these features would be useful. In the experiment, users of a job scheduling application liked active help and performed be...

The d-ary back-to-back tree of height k, BBT k d , consists of two complete d-ary trees of height k the leaves of which are identiied. For a proper coloring of the edges of BBT k d with c d + 1 colors, we consider periodic gossiping, i.e. full-duplex all-to-all broadcasting in the 1-port model where communication is made on a link of color i at any time (round) i mod c. We present a coloring fo...
