Master's Thesis Electronic Gatekeeper Using ETHERNET
University of West Bohemia Faculty of Applied Sciences Department of Computer Science and Engineering Master’s thesis Electronic Gatekeeper using ETHERNET Plzeň 2019 Hamza Elghoul Místo této strany bude zadání práce. Declaration I hereby declare that this master’s thesis is completely my own work and that I used only the cited sources. Plzeň, 2 May 2018 Hamza Elghoul Abstract The aim of this thesis is the analysis and the realization of a budget 2-way communication system using ETHERNET connection, more specific- ally a door intercom station (hereinafter ”Bouncer” or "Gatekeeper"), where it is possible to make voice calls between two CLIENTS, a CALLER and a CALLEE with an acceptable to minimal delay. There are many alternative methods available for implementing such sys- tems, this project will try to compare some of these solutions and choose the most convenient platform according to a number of factors, such as band- width, processing power needed and communication protocols in question.

Whatsapp Acceptance: a Comparison Between Individualistic and Collectivistic Cultures

UAE Correspondence should be addressed to: Serri FAISAL; [email protected] Received date: 20 November 2019; Accepted date: 7 May 2020; published date: 16 June 2020 Copyright © 2020. Serri FAISAL and Ghassan AL-QAIMARI. Distributed under Creative Commons Attribution 4.0 International CC-BY 4.0 Abstract Social media applications led by WhatsApp have exhibited a great adoption rate in individualistic and collectivistic societies. To study the factors which influence the adoption of software applications across cultures, the application design was studied by researchers in both individualistic and collectivistic societies. Most of such studies concentrated on the application design from the developer's point of view. Differently, this research study empirically explores the factors that influence the adoption of smartphone apps, such as WhatsApp, from the user's perspective. Therefore, the focus in this paper is on the moderating effect of Hofstede’s cross- cultures dimension, individualism vs. collectivism (IDV), and the interconnection between the persuasive system design (PSD) and acceptance. A total of 488 responses were collected from societies which span on the spectrum of IDV to include two individualistic societies, Netherlands and Germany, and two collectivistic societies, Malaysia and the Kingdom of Saudi Arabia. The overall results indicate that persuasive design principles are relevant to cultures across the globe. -

Icaeyeblinkmetrics() Version 3.2
Documentation for: icaeyeblinkmetrics() Version 3.2 This EEGLAB toolbox is designed for automated/semi-automated selection of ICA components associated with eye- blink artifact using time-domain measures. The toolbox is based on the premises that 1) an ICA component associated with eye blinks should be more related to the recorded eye blink activity than other ICA components, and 2) removal of the ICA component associated with eye blinks should reduce the eye blink artifact present within the EEG following back projection. Other than the EEG input, the only required input for the function is specification of the channel that exhibits the artifact (in most cases the VEOG electrode). This can either be stored within the EEG.data matrix or within EEG.skipchannels. It will then identify eye-blinks within the channel to be used for computation of the metrics listed below. If you are not sure what channel to choose, you can let the function determine the channel where the artifact maximally presents but this does slow the function down. The toolbox does not change the data in any way, it only provides an output stored in ‘EEG.icaquant’ providing: 1. Metrics: a. The correlation between the measured artifact in the artifact channel and each ICA component. (i.e. how similar the ICA component is to the eye blink) b. The adjusted normalized convolution of the ICA component activity with the measured artifact in the artifact channel. (i.e., how well does the ICA component overlap with the eye blink) c. The percent reduction in the artifact present in the EEG for each ICA component if it was removed. -
Polycom Realpresence Trio ™ Hands-On Testing of an All-In-One Audio, Content, and Video Conferencing Device for Small Meeting Rooms
June 2017 Evaluation of Polycom RealPresence Trio ™ Hands-on testing of an all-in-one audio, content, and video conferencing device for small meeting rooms. This evaluation sponsored by: Background Founded in 1990 and headquartered in San Jose, California, Polycom is a privately-held 1 company that develops, manufactures, and markets video, voice, and content collaboration and communication products and services. The company employs approximately ~ 3,000 people and generates more than $1B in annual revenue. Polycom has been in the conference phone business since the early 1990s2, and to date has shipped more than six million analog and digital conference phones – all with the familiar Polycom three-legged “starfish” design (see images below). In October 2015, Polycom announced the RealPresence Trio 8800 – a multi-function conferencing device intended for use in small, medium, and large meeting rooms. Figure 1: Polycom SoundStation IP4000 (L) and Polycom RealPresence Trio 8800 (R) In April 2017, Polycom commissioned members of our South Florida test team to perform a third-party assessment of the RealPresence Trio 8800 solution. This document contains the results of our hands-on testing. Note – For readability and brevity’s sake, throughout this document we will refer to the Polycom RealPresence Trio 8800 as the Trio 8800 or simply Trio. 1 Polycom was acquired by private equity firm Siris Capital in September 2016 2 Source: https://en.wikipedia.org/wiki/Polycom#Polycom_audio_and_voice © 2018 Recon Research | www.reconres.com | Page 2 Understanding -
