Abstract The wide spread use of solar energy and photovoltaic solar cells attracts researchers to work hard for the objective of improving their performance to be a viable attractive alternative to fossil fuels. This work presents the optimization of the output power of a photovoltaic solar cell to harvest maximum power. The power is optimized based on PVP full tracking of the sun and the effect of the tilt, the azimuth, and the incidence angles on its performance. A meta-model is utilized as a tool in the optimization technique. A case study which develops 2nd, 3rd, and 4th order hyper-surface equations that depend on day and hour to get the optimum tilt angle and optimum azimuth angle for the city of Hurghada in Egypt. The power produced from the polynomial meta-model algorithm is higher by 25.5% over the fixed tilt and azimuth angles. The developed equations from the meta-model optimization technique can be used in tracking control systems to get optimum tilt and optimum azimuth angles at any hour and at any day. By comparing the metamodel and the lengthy performance optimization technique, the error is around 1.1%. Comparison has also been made between the cost of the fixed and full tracking photovoltaic systems.

Abstract Energy democracy hopes to foster community engagement and participation in shaping our transition from fossil fuels to a renewable energy-based economy. These considerations result from critiques by environmental justice, climate justice, and just transition advocates. Although many are sympathetic to energy democracy ideals, climate goals often are articulated in math terms. This essay defines the aforementioned key terms and asks: what are the limitations and possibilities of engaging publics when climate action solely is articulated in numbers? A compelling case study is the City of Boulder – recognized as a global leader in climate science and a national leader in innovative environmental planning. This essay shares work from 2016, when the City shared a climate action plan for public feedback, supported several public participation events, and passed climate action legislation goals. We argue a just transition and energy democracy ideals are hindered if we reduce climate goals to math.

<p><strong>Keywords:</strong> External costs, mobility, environmental costs, social costs, monetarization</p> <p> </p> <p><strong>Purpose: </strong>This study provides a methodology to evaluate the environmental and social costs, which arise from traffic in the German city of Augsburg. Social costs are driven by air pollutants such as nitric oxides or particulate matter, causing health damages. Environmental follow-up costs are driven by the emission of greenhouse gases. Furthermore, approaches for a successful transformation towards a car-free city are shown.</p> <p><strong>Method: </strong>Based on traffic data from the Augsburg Civil Engineering Office, as well as traffic shares from the German Federal Motor Transport Authority, the average emission factors of vehicles on Augsburg´s streets and, subsequently, the total traffic emissions on municipal roads in the city are quantified. The environmental as well as the social consequences are monetarized using the cost rates by Matthey and Bünger (2019) and van Essen et al. (2019). Social costs are additionally assessed using to the DALY approach. Therefore the DALYs lost due to air pollutants are determined and costs per DALY are calculated using the willingness to pay-approach by Cropper and Khanna (2014) and Spengler (2004) additionally to a method by Daroudi et al. (2019) assessing health care expenditures.</p> <p><strong>Results:</strong> Applying this framework to the case study of Augsburg, results show, that environmental costs of 140.6 Million € arise from traffic in the city per year. These costs are entirely attributable to car traffic (77.7%), truck traffic (19.8%) and motorcycle traffic (1.9%), as public transport in Augsburg is climate neutral. Further, traffic on municipal roads in Augsburg causes a loss of 212.3 DALYs per year, which equals to annual social costs of 27.2 Million €. Cars account for 63.2% of those, trucks for 33.8%, motorcycles for 2.3% and buses for 0.2%, respectively. With a proportion of passenger kilometers of 90.4% from cars, 6.1% from motorcycles and 3.6% from buses, it is evident that cars contribute disproportionately to the environmental and social costs of Augsburg's traffic.</p> <p><strong>Conclusion:</strong> The social and economic follow-up costs of transport in the city of Augsburg are currently not borne by the polluter. Their great amount encourages measures, such as reinforcing the use of bicycles or public transport, eventually facilitating a change towards sustainable traffic in Augsburg.</p> <p> </p> <p><strong>References</strong></p> <p>Cropper, Maureen; Khanna, Shefali (2014): How Should the World Bank Estimate Air Pollution Damages?

Abstract. Nowadays, people in most parts of the world always visit, travel and have fun in their cities or other cities, and they spend considerable time and money in their city or in other cities as a tourist. The existence of an intelligent and automated system that can provide the most suitable recreational and cultural offerings at any time and place, with regard to financial capability and time and transport constraints, as well as individual interests and personalization; has always been felt. Recommender systems can be used to suggest suitable recreational options for the user. The main difference between the recommendation model in this study and the previous models is to focus on the short-term planning of a few hours for one day. Previous models were often based on planning a few days a week or days of the month. Also, the cost factor has been considered in this research, which has been less considered in previous models. We used collaborative filtering based on logistic regression to predict whether a type of places is a proper proposition to a user or not. Our case study is about recommending the board game cafés in the city of Kerman, Iran and the result shows that mixed groups between 15 to 30 years old are the best target and our model can predict if board game café is a good suggestion to different users. We used correlation based recommender systems when board game cafes are a proper suggestion for a user and there are at least two options for the user. In case there is no information about the user and his previous rating, popularity based recommender system can be useful. We also used content based recommender systems to give recommendations by having some background information about previous itineraries of a user and his rating to those.

Traveling Salesman Game

This paper studies cost allocation for the bus transportation service in Castellanza, a small town (14,000 inhabitants ca.) close to Varese, Italy. Carlo Cattaneo University (LIUC) is one of the promoters and funders of this service, together with the City Council and other private agents. The case study is first analysed as a traveling salesman problem (TSP) to find the optimal route. Then the traveling salesman game (TSG) is introduced, where the bus stops are associated with the players of a cooperative game, thus allowing the study of possible allocations of the total cost among them. The optimal route is found by the Branch and Bound algorithm. The Shapley vector and the separable and nonseparable cost are the methods used to allocate the cost of the optimal route among players.

The paper proposes a methodological approach to support the multi-objective (i.e. cost and structural performance) optimization of complex systems, typical of the oil & gas sector. The complexity is managed through a double-level of optimization. The first one, based on simplified product models (1-D and 0-D), considers an analytical approach for the structural behavior and a parametric one for the cost estimation. The second level considers the use of a 3-D FEM solver for structural simulations, and an analytical tool for the cost estimation. As case study, the paper proposes the design optimization of an oil & gas chimney for gas turbines. The workflow analyzed during the case study describes the use of a multi-objective and multi-level approach to optimize cost, weigh, and structural behavior of oil & gas ducts.
