in recent decades, extensive studies in order to achieve sustainable patterns of cities and settlements have done in the global arena. that two of the most important theory is urban village in the 80’s and timeless patterns of christopher alexander in the late 70s. jane jacobs and christopher alexander’s ideas, in many aspects provide the context for the idea of an urban village. urban village ...

This study aims to shed light on the correlation between spatial composition and indoor airflow as a passive design used in contemporary tube houses Ho Chi Minh City (HCMC), Vietnam. In this constraint housing typology due rapid urbanization, clarifies patterns of living room bedroom for their architectural environmental characteristics such placement, openness, area wind path. By revealing var...

The Internet of Things (IoT) is a technological topic with a very important societal impact. IoT application domains are various, such as smart cities, precision farming, smart factories, smart buildings, etc, and the diversity of these application domains is the source of the very high technological heterogeneity in the IoT, leading to interoperability issues. The semantic web principles and t...

We present a mechanism that puts users in the center of control and empowers them to dictate the access to their collections of data. Revisiting the fundamental mechanisms in security for providing protection, our solution uses capabilities, access lists, and access rights following well-understood formal notions for reasoning about access. This contribution presents a practical, correct, audit...

Solving technical problems with complex systems and integrating the many technologies employed in these multifaceted structures has been a recurring theme in Smart Cities research. This paper presents an analysis of the reason this problem has been so well explored but persists with no solution widely available. The problem is viewed as a combination of Smart City needs, governance, and increas...

The problem of determining which permutations can be sorted using certain switchyard networks is a venerable problem in computer science dating back to Knuth in 1968. In this work, we are interested in permutations which are sortable on a double-ended queue (called a deque), or on two parallel stacks. In 1982, Rosenstiehl and Tarjan presented an O (n) algorithm for testing whether a given permu...

Current smart-home and automation systems have reduced generality and modularity, thus confining users in terms of functionality. This paper proposes a novel system architecture and describes the implementation of a user-centric smart-home gateway that is able to support home-automation, energy usage management and reduction, as well as smart-grid operations. This is enabled through a middlewar...
