Electricity is one of the most important resources for the growth and sustainability of the population. This paper assesses the energy consumption and user satisfaction of a simulated air conditioning system controlled with two different optimization algorithms. The algorithms are a genetic algorithm (GA), implemented from the state of the art, and a non-dominated sorting genetic algorithm II (NSGA II) proposed in this paper; these algorithms control an air conditioning system considering user preferences. It is worth noting that we made several modifications to the objective function’s definition to make it more robust. The energy-saving optimization is essential to reduce CO2 emissions and economic costs; on the other hand, it is desirable for the user to feel comfortable, yet it will entail a higher energy consumption. Thus, we integrate user preferences with energy-saving on a single weighted function and a Pareto bi-objective problem to increase user satisfaction and decrease electrical energy consumption. To assess the experimentation, we constructed a simulator by training a backpropagation neural network with real data from a laboratory’s air conditioning system. According to the results, we conclude that NSGA II provides better results than the state of the art (GA) regarding user preferences and energy-saving.

Background “Digital Partners” is an intergenerational information and communications technology learning project carried out in the municipalities of Vic and Centelles (Catalonia) from April to May 2018. Within the framework of the introduction of community service as a subject in secondary education, the Centre for Health and Social Studies (University of Vic) created a training space with 38 intergenerational partners (aged 14-15 years and >65 years), with the aim of improving the senior users’ digital skills in terms of use of smartphones and tablets, thus helping reduce the digital divide in the territory. Objective The aim of this paper is to evaluate the satisfaction of both junior and senior participants toward the intervention and to explore its main drivers. Methods Participants who volunteered to participate in the study were interviewed. Quantitative and qualitative data gathered in paper-based ad hoc surveys were used to assess participants’ satisfaction. Results The experience shows a broad satisfaction of both junior and senior users. The project’s strengths include the format of working in couples; randomly pairing individuals by operating system; the ability to practice with the device itself; individuals’ free choice to decide what they wish to learn, develop, or practice; and the availability of voluntary practice material that facilitates communication and learning. With regard to aspects that could be improved, there is a need to review the timetabling flexibility of meetings to avoid hurrying the elderly and to extend the project’s duration, if necessary. Conclusions This activity can serve to create mutual learning through the use of mobile devices and generate security and motivation on the part of the seniors, thus reducing the digital divide and improving social inclusion.

In this paper, we review the definition of the learner choices from the Learner-driven Learning paradigm for e-learning systems. After this, we analyze how different categories of e-learning systems enable the user to make these choices, such as Serious Games. We present in detail how AdaptWeb platform makes available these choices to learner users. Additionally, we present a satisfaction survey performed after an online course on AdaptWeb platform. The survey questions were about making choices during learning and about the way AdaptWeb makes the choices available to learner-users. Summarizing the results, students enjoyed being able to make choices about their own learning and felt that this possibility was beneficial to their learning. Moreover, they liked the way AdaptWeb makes the choices available to students. Most of the students found the system easy to use, intuitive, and the student's choices were explicit and easy to take.

Buildings play a significant role in our economy and society. Substantial capital is invested in buildings, and they are the locales where a large portion (e.g., work, cultural, religious, social and personal activities) of our lives are conducted. Despite the significant monetary and temporal investments in buildings, building performance evaluations (BPEs) are not standard practice. From BPEs that have been conducted, important findings have been identified. Significant gaps frequently exist between the design intent of buildings and their measured performance (e.g., energy and water consumption) and user satisfaction (e.g., thermal comfort, lighting, noise). Environmental (e.g., resource consumption) and economic drivers (e.g., productivity, operational costs) are spurring the growth of BPEs. A BPE was conducted of the Weston Public Library (WPL) with the intent of informing a retrofit strategy and developing a protocol for conducting BPEs in the Toronto Public Library (TPL) system.

This article is aimed at demonstrating the possibilities of using the usability testing method in the framework of research to determine the features of the new forms of digital urban participation by Russians in solving social and environmental problems and conflicts. In particular, the authors investigated the effectiveness of environmental online platforms in the UX research methodology through usability testing of these sites from the perspective of their users. The results of testing showed that both the functionality of these platforms to involve the population in environmental practices and technical limitations prevent users from putting environmental initiatives into practice. The data obtained in the framework of the UX study will allow us to compare the perception of users of online platforms with the conceptual vision of their developers to identify potential biases in the perception of these products by their ideologues and users in order to minimize these gaps. In terms of the increase of scientific knowledge, this study will allow to assess the effectiveness of the use of information and communication technologies (ICTs) for digital ecoactivists in comparison with traditional (offline) forms of urban participation, to analyze the new strategies and forms of digital participation, and to identify the main advantages and disadvantages of ICTs in minimizing socio-environmental problems and conflicts in the tradition of M. Castells, digital environmental humanities/ English version of the article on pp. 86 - 94 at URL: https://panor.ru/articles/possibilities-of-using-usability-testing-for-scientific-research-in-assessing-user-satisfaction-with-the-activities-of-environmental-digital-platforms/50575.html

In its most generic sense, the user-centric view in telecommunications considers that the users are free from subscription to any one network operator and can instead dynamically choose the most suitable transport infrastructure from the available network providers for their terminal and application requirements. In this approach, the decision of interface selection is delegated to the mobile terminal enabling end users to exploit the best available characteristics of different network technologies and network providers, with the objective of increased satisfaction. In order to more accurately express the user satisfaction in telecommunications, a more subjective and application-specific measure, namely, the Quality-of-Experience (QoE) is introduced. QoE is the core requirement in future wireless networks and provisions. It is a framework that optimizes the global system of networks and users in terms of efficient resource utilization and meeting user preferences (guaranteeing certain Quality-of-Service [QoS] requirements). A number of solution frameworks to address the mentioned problems using different theoretical approaches are proposed in the research literature. Such scholarly approaches need to be evaluated using simulation platforms (e.g., OPNET, NS2, OMNET++, etc.). This chapter focuses on developing the simulation using a standard discrete event network simulator, OPNET. It outlines the general development procedures of different components in simulation and details the following important aspects: Long Term Evolution (LTE) network component development, impairment entity development, implementing IPv6 flow management, developing an integrated heterogeneous scenario with LTE and WLAN, implementing an example scenario, and generating and analyzing the results.
