‎in this article‎, ‎we have focused one some basic and productive information about the properties of spectrum and singular values related to compact operators which are ideals in a c*-algebra of bounded operators‎. ‎considering a two-sided connection between the family of symmetric gauge functions on sequence of singular values of compact operators and symmetric norms on finite dimensional ope...

The market mechanism of spatial resource allocation is examined in a system of cities, where social welfare depends on city size. The competitive dynamics of the system is a product of the interplay between people’s individual exit type choices (migration) and their collective voice type choices (urban governance). It is shown that the use of efficiency enhancing measures of urban governance de...

Despite the fact that image texture features extracted from high-resolution remotely sensed images over urban areas have demonstrated their ability to distinguish different classes, they are still far from being ideal. Multiresolution grayscale and rotation invariant texture classification with Local Binary Patterns (LBPs) have proven to be a very powerful texture feature. In this paper we perf...

    One of the critical issues related to sustainable urban twenty-first century urban growth pattern, and today most researchers believe a significant relationship between physical development of the city (urban form) and urban sustainability.

This article deals with the increasingly digital augmentation of urban space and looks at how so far initiatives in this sense have been deployed in a way that is disconnected from urban design knowledge and practice. The aim here is to contribute to a reflection on how urban design perspectives can – and should – play an important role in informing such developments. It promotes, through a ser...

We present our approach on how smart city technologies may enhance the learning process. We have developed the CLIO urban computing system, which invites people to share personal memories and interact the collective city memory. Various educational scenarios and activities were performed exploiting CLIO; in this paper we present the methodology we followed and the experience we gained. Learning...

Over 70% of the population in developed countries live in cities. World wide, the average urban population proportion is 42% (World population reference, 1993). Urbanization creates significant changes in land use and land cover, affecting the structure, pattern and function of the ecosystem. The public is increasingly concerned about how these changes influence our daily life and the sustainab...

Under the assumption of perfect competition, it is difficult to avoid the conclusion that abandoned properties and long undeveloped neighborhoods remain that way because they are unprofitable. In contrast, this paper introduces a model in which firms systematically overlook neighborhoods with little commercial activity because of a positive informational externality motivating later movers to c...

This chapter considers the literature on urbanization and migration to cities from rural areas in developing and middle-income countries. The chapter assesses recent patterns, discusses traditional models, addresses more recent models of migration, presents some of the recent findings from the micro-econometric literature, and closes with a discussion of the role of cities in economic growth. C...
