Social participation in the aspect of a smart city development

Advanced technologies are entering citizens’ lives, which can be noticed at every turn. Society is becoming increasingly involved in building, creating and planning a city, district or the nearest place of residence. The quality of the functioning of the local community and the quality of life depend, to a large extent, on the level of social participation. The aim of social participation is to establish a mechanism for meeting citizens’ needs, and to achieve citizens’ acceptance of the authorities’ actions. Modern communication techniques greatly facilitate the expression of public opinion and public awareness in this regard has been on the rise. A growing number of new forms of communication using modern technologies are being developed all the time. The aim of the study is to analyse the forms of social participation in the city life, inter alia spending financial resources on its development. Attention is also drawn to the most recent ways in which the authorities communicate with the public in order for the latter to express their opinions on the former’s actions. Practical research was conducted for the city of Olsztyn located in the north-eastern part of Poland. Social activity forms were analysed, including those carried out using ICT technologies. The research shows that access to modern technologies facilitates contact between the city authorities and citizens, which ensures that the policy under implementation is kept in line with citizens’ expectations

Realtime Multilevel Crowd Tracking using Reciprocal Velocity Obstacles

We present a novel, realtime algorithm to compute the trajectory of each pedestrian in moderately dense crowd scenes. Our formulation is based on an adaptive particle filtering scheme that uses a multi-agent motion model based on velocity-obstacles, and takes into account local interactions as well as physical and personal constraints of each pedestrian. Our method dynamically changes the number of particles allocated to each pedestrian based on different confidence metrics. Additionally, we use a new high-definition crowd video dataset, which is used to evaluate the performance of different pedestrian tracking algorithms. This dataset consists of videos of indoor and outdoor scenes, recorded at different locations with 30-80 pedestrians. We highlight the performance benefits of our algorithm over prior techniques using this dataset. In practice, our algorithm can compute trajectories of tens of pedestrians on a multi-core desktop CPU at interactive rates (27-30 frames per second). To the best of our knowledge, our approach is 4-5 times faster than prior methods, which provide similar accuracy

Noise Effect of Building Installation

Environmental state of domiciliation influenced basically by the noise load, which nowadays is the most important quality criterion. The paper shows investigation of authors and conclusions about actual questions of building installation equipment noise. | Calitatea mediului înconjurător al locuinţelor este esenţial influenţată de nivelul de zgomot, care, în zilele noastre este un criteriu calitativ important. Lucrarea prezintă cercetările şi concluziile autorilor privind problemele actuale de zgomot ale echipamentelor instalaţiilor interrioare din clădiri
