Smart City Architecture： A Technology Guide for Implementation and Design Challenges

Urban development is becoming increasingly reliant on effective use of intelligent services.In the process of providing better services to all citizens and improving the efficiency of administration processes,the concept of a smart city has been lauded as a promising solution for the coming challenge of global urbanization.However,due to the broad scope of smart cities their definition has not been standardized,thus proposed architectures are diverse.This work proposes a new architecture from the perspective of the data that underpins all the functionality of smart cities.The proposed architecture is discussed,outlining design challenges and offering insight into the development of smart cities.

Ethics Aware Object Oriented Smart City Architecture

A novel initiative in providing advanced civic amenities is the idea of smart city driven by the lnternet of Things. Owing to a lack of consensus regarding what constitutes a smart city, diverse smart city architectures have been proposed. However, it is observed that adequate consideration is not given to the most important element of a smart city i.e. its people. In our opinion, energy efficient technologically driven city does not necessarily lead to a smart city. Ethics, tradition and law form essential ingredients of complex social palette that cannot be ignored. In this work we propose Ethics-Aware Object-Oriented Smart City Architecture （EOSCA） that has two distinguishing features. Firstly, we propose an object oriented layered architecture where an object represents an abstraction of a real world thing along with requisite security and ethics parameters. Secondly, we propose to integrate socio-cultural and ethical aspects within the smart city architecture by dedicating a separate ethics layer. Such enhancement not only addresses the challenge of privacy and security of a smart city, but also makes it people friendly by incorporating ethics. Such measures would facilitate social acceptance of smart city paradigm and augment its economic value.

Architectural Design Strategies for Smart Cities

The rapid development of science and technology in China has given rise to the concept of a smart city.A smart city has certain characteristics of integration and extensiveness,making it a popular topic for discussion.The emergence of smart cities brings about changes to people’s lifestyles,promotes economic development,and results in the innovation of environment protection work.Therefore,urban buildings should be designed based on the smart city concept to better meet people’s demands.Therefore,this article describes the definition of smart buildings and smart cities,the characteristics of smart city concepts,and the importance of smart city concepts in architectural design.Lastly,smart city architectural design strategies are proposed.

DAUNet: Detail-Aware U-Shaped Network for 2D Human Pose Estimation

Human pose estimation is a critical research area in the field of computer vision,playing a significant role in applications such as human-computer interaction,behavior analysis,and action recognition.In this paper,we propose a U-shaped keypoint detection network(DAUNet)based on an improved ResNet subsampling structure and spatial grouping mechanism.This network addresses key challenges in traditional methods,such as information loss,large network redundancy,and insufficient sensitivity to low-resolution features.DAUNet is composed of three main components.First,we introduce an improved BottleNeck block that employs partial convolution and strip pooling to reduce computational load and mitigate feature loss.Second,after upsampling,the network eliminates redundant features,improving the overall efficiency.Finally,a lightweight spatial grouping attention mechanism is applied to enhance low-resolution semantic features within the feature map,allowing for better restoration of the original image size and higher accuracy.Experimental results demonstrate that DAUNet achieves superior accuracy compared to most existing keypoint detection models,with a mean PCKh@0.5 score of 91.6%on the MPII dataset and an AP of 76.1%on the COCO dataset.Moreover,real-world experiments further validate the robustness and generalizability of DAUNet for detecting human bodies in unknown environments,highlighting its potential for broader applications.

About the Relationship between Human and Landscape Architecture

The relationship between human and landscape architecture was explored by studying a poem of Bian Zhilin. From the perspectives of social value of landscape architecture, relationship between human and landscape architecture and integrality of landscape architecture, it was proposed that human was also a component of landscape architecture, and participation of human realized the social value of landscape architecture, moreover, human was a kind of landscape while landscape architecture was regarded as a "drama", thus only landscape architecture used by human was a complete one.

A Triple Human-Digital Twin Architecture for Cyber-Physical Systems

With the development of information and communication technology and the advent of the Internet of Things(IoT)era,cyber-physical system(CPS)is becoming the trend of products or systems.The deep integration and real-time interaction between the physical world and the virtual world expand system functions.Although there are some CPS implementation guidelines,the virtual world is still relatively abstract compared to the concrete physical world that can be touched through the IoT.Besides that,human is a non-negligible CPS endogenous interactive intelligent component.In this paper,we propose a triple human-digital twin architecture,where the physical objects and the digital twins that are the projections of the physical entities establish the cornerstone of human functioning together.And the hierarchically distributed digital twins grow dynamically with the physical entities along the lifecycle.Furthermore,the interaction and collaboration among the physical objects,the digital twins,and the humans in their respective worlds(the expected world,the interpreted world,and the physical world)integrate the full value chain of the products in anticipation of seamless synergy.Finally,we present a power management digital companion platform for the lunar probe to demonstrate the efficacy of the architecture.

Attaining Human Aspects to Avoid Alienation in Architecture

Architectural practice during the last century was influenced by Western architectural theories.These theories were reflections of the contradictions of human beings’lives:the result was contradictions in architecture.The research aims to launch a view of the fundamentals of what we might call Muslim architectural theory,fundamentals that can control the future of architecture.Thus,it offers a set of principles coming from Muslim thought;these principles highlight humanitarian needs to be fulfilled by architecture.This paper makes the following assumptions:(1)Re-forming architecture requires re-forming the human.(2)The interaction between the social environment on one side and the built environment on the other side achieves human comfort.(3)Principles derived from Muslim thought set up general rules that can order architectural practice.Based on these theories,this paper has a goal of crystallizing a new theory that governs present-day architecture.Thus,the paper studies human needs in architecture.Besides,it has an implementation part to explain how architecture fulfills human needs.It further shows the extent to which the built environment can satisfy those needs.The research includes thirty needs traced from Muslim thought.Consequently,the research examined the presence of these needs in one traditional Arabian house.

Modeling the dynamic alignment of business and information systems via the lens of human-centered architecture evolution

The complexity of business and information systems(IS)alignment is a growing concern for researchers and practitioners alike.The extant research on alignment architecture fails to consider the human viewpoint,which makes it difficult to embrace emergent complexity.This paper contributes to the extant literature in the following ways.First,we combine an enterprise architecture(EA)framework with a human viewpoint to address alignment issues in the architecture design phase;second,we describe a dynamic alignment model by developing a humancentered meta-model that explains first-and second-order changes and their effects on alignment evolution.This paper provides better support for the theoretical research and the practical application of dynamic alignment.

Knocking Walls Down:Queer Architecture and Creative Cities

Based on bibliographic research,the article analyzes how queer architecture challenged gentrification,real estate speculation,and segregation of minorities in creative cities.The results show that the architecture of queer spaces can be understood as a practice of gender and sexual resistance and biopolitical disobedience,as the capitalist architecture worked as a biopolitical technology for producing gender and sexuality and shaping political and sexual identities through techniques of surveillance and the construction of the public/private divide for controlling gender and sexual reproduction.

A Structural Model of the Endogenous Human BAF Complex Informs Disease Mechanisms

Mammalian SWI/SNF complexes are ATP-dependent chromatin remodeling complexes that regulate genomic architecture.Here,we present a structural model of the endogenously purified human canonical BAF complex bound to the nucleosome,generated using cryoelectron microscopy(cryo-EM),cross-linking mass spectrometry,and homology modeling.

Spatio-temporal Variation of Landscape Heterogeneity under Influence of Human Activities in Xiamen City of China in Recent Decade

Xiamen is an economically competitive and highly urbanized city along the coastal area of Fujian Province, China. The research on spatio-temporal variation of landscape heterogeneity under the influence of human activities is of great importance to the further study on the relationship of landscape pattern and ecological process. It is also crucial to the discovery of spatial variation and intensity distribution of human activities. The research analyzed the intensity of human impacts and the spatial variation features and dynamics of landscape patterns by introducing statistical theories and approaches. We analyzed spatio-temporal variation of landscape heterogeneity using the geostatistical techniques, such as semivariogram and Kriging interpolation.Results show that there is a higher correlation between landscape heterogeneity indexes and human impact index. Both the indexes show a moderate spatial autocorrelation as well as an obvious characteristic of anisotropy. From 1998 to 2008, the spatial differentiation of the changes in the intensity of human activities and the changes in landscape heterogeneity shows that the landscape patterns in Xiamen are closely related with the urban land utilization methods, the condition of traffic and geographical location and the physical geographical condition such as the terrain and the ecological environment. The process of urbanization has a significant impact on the urban landscape pattern.

Mass Human Migration and the Urban Heat Island during the Chinese New Year Holiday: A Case Study in Harbin City, Northeast China

Many Chinese people leave big cities for family reunions during the Chinese New Year （CNY）, which is the most important public holiday in China. However, how modem mass human migration during the CNY holiday affects the urban heat island （UHI） is still un- known. Here, the authors investigate the role of modem human migration for the UHI effects during the CNY holiday for the period of 1992-2006 in Harbin City, Northeast China. The results show that during the CNY week, the UHI effects expressed as daily mean, maxi- mum, and minimum temperature differences between urban and rural stations averaged over the period of 1992-2006 are 0.65℃ （43%）, 0.31℃ （48%）, and 1.14℃ （71%） lower than during the background period （four weeks before and four weeks after the CNY week）, re- spectively. Our findings identify previously unknown impacts of modem mass human migration on the UHI effects based on a case study in Harbin City.

Empirical Research on Carrying Capacity of Human Settlement System in Dalian City, Liaoning Province, China

Using the theories of population carrying capacity and ecological elasticity in other fields for reference, the connotation of regional human settlement system was defined from the viewpoint of the complex relationship among the factors such as regional population, resources, environment and economic and social development in the context of China′s rapid urbanization. Then the concept and characterization methods of the regional human settlement carrying capacity were proposed by means of population scale. Furthermore, a model of carrying capacity-pressure-state-response(CPSR) on regional human settlement system was established by referencing pressure-state-response(PSR) model, and the Catastrophe Theory was introduced to determine the corresponding standards of multi-criteria programming and evaluation. Taking Dalian City, Liaoning Province, China as an example, an empirical analysis on evaluation of human settlement system from 2000 to 2012 was carried out. The results showed that the carrying capacity of human settlement system in Dalian was fluctuating between 9.6 × 106 to 10 × 106 persons with a quantitative stage of the dynamic regulation. During the research period the load index of human settlement system in Dalian dropped from 0.96 to 0.84 with a lower pressure of human settlement system than the national average level. And the emergency response grades of human settlement system in Dalian were kept in grade Ⅱ(orange warning) or grade Ⅲ(yellow warning). Human settlement system of Dalian was in slight security state as a whole, but the load had a tendency of increase in recent years. The related departments should pay close attention to regional human settlement system and take active measures to improve human settlement by both intensity control and total quantity control. By comparison, analysis and discussion, it was considered that the results were basically accordded with the current situations of human settlement in Dalian, and the evaluation results were more reliable, visualized and easily applied in practice. Therefore, the above-mentioned concepts, characterization and evaluation methods of the regional human settlement system and carrying capacity could provide a new thought and method for quantitative evaluation of human settlement.

A Socio-Technical Perspective on the Design of IT Architectures:The Lowlands Lens

The paper aims at developing a more comprehensive design theory for designing effective IT architectures based on organizational design principles.It builds on the sociotechnical systems design theory(STS-D)for the design of work,workplaces,and organizations as developed in the Lowlands(The Netherlands and Belgium).Traditional sociotechnical approaches study the effects of the technical system on the social system and try to jointly optimize both systems by end-users’participation.The Lowlands STS-D approach focuses on creating organizational conditions for developing humane and productive organizations.Organizations are considered as social systems.Technical systems need to support the effective functioning of work and control of work within that social system.Therefore,the division of labour is central in the Lowlands STS-D approach.It is articulated in designing the execution tasks(production structure)and control tasks(control structure).Furthermore,it claims that the design of IT architecture follows after organizational design of the production and control structure.This boils down to the design of provisioning of information needed at workplaces and between workplaces.To understand the Lowlands approach for designing IT architecture,called archipelago,we will first in-depth explain its organizational design principles and sequence,and its application for designing IT architecture,which is becoming ever more feasible with new technologies.Furthermore,with this paper we attempt to bridge the different languages used by organizational and IT designers as they should jointly work on the same outcome:humane and productive organizations.
