Pathway using WUDAPT's Digital Synthetic City tool towards generating urban canopy parameters for multi-scale urban atmospheric modeling

2019

Abstract The WUDAPT (World Urban Database and Access Portal Tools project goal is to capture consistent information on urban form and function for cities worldwide that can support urban weather, climate, hydrology and air quality modeling. These data are provided as urban canopy parameters (UCPs) as used by weather, climate and air quality models to simulate the effects of urban surfaces on the overlying atmosphere. Information is stored with different levels of detail (LOD). With higher LOD greater spatial precision is provided. At the lowest LOD, Local Climate Zones (LCZ) with nominal UCP ranges is provided (order 100 m or more). To describe the spatial heterogeneity present in cities wi…

The Sustainability of Cruise Tourism Onshore: The Impact of Crowding on Visitors’ Satisfaction

2019

The sustainability of cruise tourism has been questioned in relation to its negative effects on ports of call, among which crowding has recently become more pronounced. However, an understanding of how crowdedness influences cruise tourists&rsquo

Communication structure and collective actions in social media

2010

In this paper I present results a study of different types of social media communication and networking channels that allow for collective action (CA): Twitter, Jaiku / Qaiku, Ning and Facebook. My preliminary findings indicate, that the visual outlining and the structure of communication create different kinds of collectivity and collective actions. A status stream is effective for simple and fast repetitive mass actions and for individual mass broadcasting, while channels and threads are needed as a backchannel for more complicated, coordinated and iterative tasks and support a sense of community. When planning collective action on the Internet, ranging from citizen participation to marke…

Understanding the crowdfunding phenomenon and its implications for sustainability

2019

Abstract Nonetheless the large body of knowledge rapidly accumulated on crowdfunding as well as the growing relevance of this phenomenon for sustainability, there are very few studies on the role of crowdfunding for sustainability-oriented projects, and many related issues are still far from being fully understood. This signalises a clear need for unveiling the main dynamics of the relationship between crowdfunding and sustainability, and also opening up useful directions for future research on this relationship. To conceptualize the implications of crowdfunding for sustainability, we propose and use a framework, encompassing five dimensions, namely the project creator, the backers, the cam…

BRIMA : Low-Overhead Browser-Only Image Annotation Tool

2021

Image annotation and large annotated datasets are crucial parts within the Computer Vision and Artificial Intelligence fields. At the same time, it is well-known and acknowledged by the research community that the image annotation process is challenging, time-consuming and hard to scale. Therefore, the researchers and practitioners are always seeking ways to perform the annotations easier, faster, and at higher quality. Even though several widely used tools exist and the tools’ landscape evolved considerably, most of the tools still require intricate technical setups and high levels of technical savviness from its operators and crowdsource contributors.In order to address such challenges, w…

Telia Crowd Insights -tietojen hyödyntäminen pandemiatietoisuuden parantamiseksi Keski-Suomessa

2021

Telia Crowd Insights -tietojen hyödyntäminen pandemiatietoisuuden parantamiseksi KeskiSuomessa on Keski-Suomen liiton rahoittama hanke, jolla pyritään selvittämään, että pystytäänkö ihmisten ja ihmisvirtojen liikkeitä seuraamalla saavuttamaan parempi tilannekuva pandemia tilanteessa. Hankkeen tarkoituksena on keskittyä erilaisiin liikenteenseurantaratkaisuihin sekä tutkia koronaviruksen aiheuttamia vaikutuksia maakunnassa tapahtuvaan liikenteeseen ja liikkumiseen. Keväällä 2020 tuli voimaan poikkeukselliset olosuhteet, joiden takia liikenne muuttui merkittävästi erilaisten rajoitusten ja yleisen varovaisuuden vuoksi. Tämä on yksi merkittävimmistä ilmiöistä, joita projektissa pyritään tutkim…

Analysing Incentive Strategies to Promote Participation in Crowdsourcing Systems

2016

In this paper, we define two strategies for crowdsourcing systems to encourage users to participate at a cost that is close to the optimal cost for the system. In the scenario considered, the system has temporal constraints and potential participants have dynamic behaviors related to the expected rewards (i.e., users’ expected rewards in exchange of their contributions change over time). We propose and evaluate two types of strategies that promote participation of users through monetary rewards that can change as time passes in order to adapt them to the population dynamic behaviors.

Crowd Models for Emergency Evacuation: A Review Targeting Human-Centered Sensing

2013

Emergency evacuation of crowds is a fascinating phenomenon that has attracted researchers from various fields. Better understanding of this class of crowd behavior opens up for improving evacuation policies and smarter design of buildings, increasing safety. Recently, a new class of disruptive technology has appeared: Human-centered sensing which allows crowd behavior to be monitored in real-time, and provides the basis for real-time crowd control. The question then becomes: to what degree can previous crowd models incorporate this development, and what areas need further research? In this paper, we provide a survey that describes some widely used crowd models and discuss their advantages a…
