Abstract
According to the literature, there is a research gap regarding digital advertising. This exploratory study focuses on how advertising on the social networks Instagram, Facebook and YouTube, three digital platform giants, is interpreted. Which has the most informative, most interesting, less irritating, and, as a consequence, most effective publicity? We performed a survey, which had 106 answers, and using descriptive statistics we concluded that Instagram and Facebook have better and less irritating publicity than YouTube. On Instagram and Facebook, despite 77,5% and 95,7% (respectively) of the respondents having indicated that they ignore the adverts which are presented, the quantity of people who visit and buy the advertised products is visibly higher, when compared to the numbers registered on YouTube. In contrast with YouTube, the survey sample evaluates Instagram as the platform with the most interesting publicity, in accordance with user preferences. YouTube has less direct and less segmented publicity than Instagram and Facebook.

Abstract
The great potential of Unmanned Vehicles (UV) for services is supported by the evolution of drones and their flexible ability to help us performing dangerous, boring and difficult tasks. The common communication solutions e.g., radio, consider a pilot and a vehicle in the same location. Besides, the alternatives based on Ground Control Stations (GCS) are difficult to configure, which makes it difficult for a common user and a developer to use and/or implement new services for drones. This work proposes a solution with a new messaging protocol to overcome the previous problems, allowing controlling a UV in a remote location after a simple configuration. The implementation of this approach is based on a cloud platform, responsible for UV and user management, and on TCP/IP WebSockets for the user to control remotely located vehicles, anytime and anywhere. This research starts with the analysis of the prior work regarding UV communication technologies and the available GCS. Minding the identified problems, we designed an architecture that represents a cloud platform and multiple users and UVs in different networks. To prototype this architecture, we developed the user interface, the platform and the UV control module. The functional assessment considers a generic simplified and controlled scenario, focusing on the real-time control and video stream. The results confirmed the possibility to control a UV in a different location, in real-time, with an average response time of 25ms. This work provides valuable insights regarding the communication in the fields of anytime and anywhere device control and vehicle-based services.
