Sharing economy and dynamic pricing: Is the impact of Airbnb on the hotel industry time-dependent?
2021
Abstract Prior literature has reported significant price and revenue reductions in the hotel industry due to the emergence of Airbnb. Other studies have documented that hotels' price reactions to the penetration of Airbnb depend on their service level, e.g., low/medium-end versus high end. Relying on a large sample from the Italian market, we contribute by showing that the effect of Airbnb on hotels' price decisions does not only depend on incumbents’ quality level, but also on the difference between booking and check-in time. That is, the effect of the penetration of Airbnb on hotels' dynamic price decisions varies over time depending on the core segment hotels target.
Exploring the role of the sharing economy in disasters management
2020
Abstract Improvements in information and communications technologies (ICTs) have facilitated the inclusion of the sharing economy (SE) in societies more than ever. In the aftermath of recent disasters, the SE played significant roles to help the affected people and support official responders. However, the literature has not effectively explored these roles, and thus, no framework can support the systematic inclusion of the SE in disasters management. This paper aims to address the gap through a two-stage exploratory research approach. First, we conduct a systematic literature review to identify the extent to which the SE is taken into consideration in disasters. After that, we investigate …
Online optimization of a multi-conversion-level DC home microgrid for system efficiency enhancement
2017
In this paper, an on-line management system for the optimal efficiency operation of a multi-bus DC home distribution system is proposed. The operation of the system is discussed with reference to a distribution system with two conversion stages and three voltage levels. In each of the conversion stages, three paralleled DC/DC converters are implemented. A Genetic Algorithm performs the on-line optimization of the DC network’s global efficiency, generating the optimal current sharing ratios of the concurrent power converters. The overall DC/DC conversion system including the optimization section is modelled using MATLAB/Simulink. Thanks to the implemented online algorithm, considering …
Market Opportunity of China Telecom 3G Toward 4G - A Social-Technical Analysis for its Future Development
2013
In the Information and communication Technology (ICT) field, the success a new player will face is the challenge for the opportunity of new market development. China's mobile subscribers grew by 9.93 millions to 1.132 billions in February 2013.The convenience of communication prompted China’s growth, but there is little information available in literature about how it happened and what the next development steps will be for the China Telecom Industry.The purpose of this paper is an attempt to picture the future growth path of China Telecom market opportunities from 3G toward 4G and beyond, including viewing this from the angles of telecom/internet e-commerce regulation development; globaliz…
Current-Sensing Technique for Current-Mode Controlled Voltage Regulator Modules
2008
This paper introduces an innovative current-sense technique for voltage regulator modules (VRMs). The proposed method is applied to a multiphase buck converter although the converter topology does not affect the accuracy or effectiveness of the proposed technique. A RC network is parallel connected with the buck converter low-side MOSFET and the voltage signal across the sense capacitor reconstructs the inductor current waveform. The RC technique benefits from all the advantages of the most popular current-sensing technique, the inductor DC resistance current-sense method, cutting off its main disadvantage. The sense network design is oriented to obtain high immunity to noise and a great dy…
Active load sharing technique for on-line efficiency optimization in DC microgrids
2017
Recently, DC power distribution is gaining more and more importance over its AC counterpart achieving increased efficiency, greater flexibility, reduced volumes and capital cost. In this paper, a 24-120-325V two-level DC distribution system for home appliances, each including three parallel DC-DC converters, is modeled. An active load sharing technique is proposed for the on-line optimization of the global efficiency of the DC distribution network. The algorithm aims at the instantaneous efficiency optimization of the whole DC network, based on the on-line load current sampling. A Look Up Table, is created to store the real efficiencies of the converters taking into account components toler…

The Impacts of ICT Support on Information Distribution, Task Assignment for Gaining Teams’ Situational Awareness in Search and Rescue Operations
2015
Information and Communication Technology (ICT) has changed the way we communicate and work. To study the effects of ICT for Information Distribution (ID) and Task Assignment (TA) for gaining Teams’ Situational Awareness (TSA) across and within rescue teams, an indoor fire game was played with students. We used two settings (smartphone-enabled support vs. traditional walkietalkies) to analyze the impact of technology on ID and TA for gaining TSA in a simulated Search and Rescue operation. The results presented in this paper combine observations and quantitative data from a survey conducted after the game. The results indicate that the use of the ICT was good in second scenario than first sce…
Small world theory and the World Wide Web: linking small world properties and website centrality
2016
This qualitative paper aims to point out the incidence of small world characteristics in the World Wide Web. To this end, some theoretical implications of small world theory (SWT) are verified using information from focus groups and in-depth interviews administered to experts and users of the World Wide Web. The purpose of this study is to investigate whether it is possible to apply small world properties to online social networks while pointing out the key variables of website centrality in that context. Building on this, the paper traces possible contributions for better management of the World Wide Web in terms of the professional use of social media to facilitate information or product …
Charge measurement using an array of Faraday’s Cups on a printed circuit board
2014
Abstract An absolute method of measuring charge is to use a Faraday Cup (FC) principle. This study relates to a novel method of measuring charge on a flat substrate, which is coated with charged powder particles. The substrate consists of an array of FC with different dimensions. The sensor is manufactured using flame-retardant printed circuit board (PCB) technology. The objective of this work is to reduce the charge sharing by developing a grounded shield cup around each conductive cup in the array and accordingly increase cup-to-ground capacitance. The results have confirmed that the improved well shielding would provide a more accurate quantitative charge measurement.
