Assessment of Energy and Economic Effectiveness of Photovoltaic Systems Operating in a Dense Urban Context
2013
A methodology that permits testing the level of integration of the photovoltaic technology in urban areas is presented. The percentage of coverage of the electricity demand of grid-connected photovoltaic systems installed on the roofs of buildings were investigated in a district of the city of Palermo (Sicily). After classifying roofs according to their shape, orientation and pitch by means of satellite images provided by Google Earth, the ratio of the productivity of the PV systems and the consumption of electricity of the households was analysed. The results of the energy assessment have been screened considering the economic feasibility of grid-connected photovoltaic systems: the energy …
Comparative Analysis of the Social, Demographic and Economic Factors that Influenced Housing Choices in Spain in 1990 and 2000
2008
The housing market is an important sector in the economy of any country. Residential demand (also referred to as `housing consumption') depends on many demographic and social characteristics of the country's population and is also related to economic factors. The aim of the present paper was to evaluate the joint effects of economic, demographic and social factors on household behaviour with respect to housing choices. In addition, an attempt was made to determine the impact of recent economic and structural changes in Spanish society (in 1990 and 2000) on residential demand. It was found that the consequences of these structural changes will have medium- and long-term effects on housing d…
Are there returns from university location in a state-funded university system?
2013
Abstract A location in an economically active, high-amenity region could in many ways be a significant advantage for a university and its students and thus could also be positively linked to students' subsequent earnings. Based on this hypothesis, the present study empirically examines the effect of university location choice on earnings in Finland, focusing on the following question: To what extent does the choice of university location explain the observed positive early-career earnings premium for students graduating from the Helsinki metropolitan area rather than from one of the nine other university cities? The results suggest that no positive average earnings premium exists for metro …
Co-Creative, Re-Generative Smart Cities. Smart Cities and Planning in a Living Lab Perspective
2014
A particularly mild approach in money supply over three decades at the international level has encouraged the piling up of substantial amounts of debt through urban investment, particularly in less competitive systems . It appears therefore necessary ato elaborate stringent "urban financial statements", through a kind of digital agenda able to provide georeferenced economic indicators about structure, value and performance of urban capital, and therefore capable to serve as a guide in future allocative choices of the myriad of holders of some stake of the above urban capital. Recognizing the role of such a multiplicity of stakeholders means to radically reconsider the transcendent assumptio…

Do Rent-Seeking and Interregional Transfers Contribute to Urban Primacy in Sub-Saharan Africa?
2006
We develop an economic geography model in which mobile skilled workers choose between working in the production sector or becoming part of an unproductive political elite. The elite sets tax rates on skilled and unskilled workers to maximize its own welfare by extracting rents, thereby influencing the spatial allocation of production and changing the available range of consumption goods. We show that such behavior increases the likelihood of agglomeration and of urban primacy. In equilibrium, the elite may tax the unskilled workers but will never tax the skilled workers, and there are rural-urban transfers towards the agglomeration. The size of the elite and the magnitude of the tax burden …
CNN-Based Prostate Zonal Segmentation on T2-Weighted MR Images: A Cross-Dataset Study
2020
Prostate cancer is the most common cancer among US men. However, prostate imaging is still challenging despite the advances in multi-parametric magnetic resonance imaging (MRI), which provides both morphologic and functional information pertaining to the pathological regions. Along with whole prostate gland segmentation, distinguishing between the central gland (CG) and peripheral zone (PZ) can guide toward differential diagnosis, since the frequency and severity of tumors differ in these regions; however, their boundary is often weak and fuzzy. This work presents a preliminary study on deep learning to automatically delineate the CG and PZ, aiming at evaluating the generalization ability o…
Training and Deployment as a Basis for Usability Engineering of Mobile Systems
2008
Usability engineering of mobile systems challenges existing methods and raises new concerns. Usability evaluations are frequently described as a separate discipline and in many cases usability evaluations are separate activities within the design and development of systems. This paper presents a development project where training in and the deployment of a mobile system were used to identify usability problems. The project aimed to develop a mobile system to supporting information processes for workers on building sites. An iterative usability evaluation process was conducted the process was refined and validated using two action research projects. The approach of the research was user-cent…
Usability remote evaluation: METBA system
2012
Usability as well as accessibility is a key aspect in development of human-computer interaction. This paper presents the basis of usability evaluation methodology and reviews the methodology used in empirical studies of usability evaluation for disabled people. Finally, we present a solution (METBA) as a system for managing the information related to evaluation of human behavioral observation contents that is used for the registration and management of the information derived from remote usability evaluation which complements the methodology commonly used in this research area.
