CleanTX Analysis on the Smart Grid

The utility industry in the United States has an opportunity to revolutionize its electric grid system by utilizing emerging software, hardware and wireless technologies and renewable energy sources. As electricity generation in the U.S. increases by over 30% from today’s generation of 4,100 Terawatt hours per year to a production of 5,400 Terawatt hours per year by 2030, a new type of grid is necessary to ensure reliable and quality power. The projected U.S. population increase and economic growth will require a grid that can transmit and distribute significantly more power than it does today. Known as a Smart Grid, this system enables two- way transmission of electrons and information to create a demand-response system that will optimize electricity delivery to consumers. This paper outlines the issues with the current grid infrastructure, discusses the economic advantages of the Smart Grid for both consumers and utilities, and examines the emerging technologies that will enable cleaner, more efficient and cost- effective power transmission and consumption.IC2 Institut

IEEE Access Special Section Editorial: Big Data Technology and Applications in Intelligent Transportation

During the last few years, information technology and transportation industries, along with automotive manufacturers and academia, are focusing on leveraging intelligent transportation systems (ITS) to improve services related to driver experience, connected cars, Internet data plans for vehicles, traffic infrastructure, urban transportation systems, traffic collaborative management, road traffic accidents analysis, road traffic flow prediction, public transportation service plan, personal travel route plans, and the development of an effective ecosystem for vehicles, drivers, traffic controllers, city planners, and transportation applications. Moreover, the emerging technologies of the Internet of Things (IoT) and cloud computing have provided unprecedented opportunities for the development and realization of innovative intelligent transportation systems where sensors and mobile devices can gather information and cloud computing, allowing knowledge discovery, information sharing, and supported decision making. However, the development of such data-driven ITS requires the integration, processing, and analysis of plentiful information obtained from millions of vehicles, traffic infrastructures, smartphones, and other collaborative systems like weather stations and road safety and early warning systems. The huge amount of data generated by ITS devices is only of value if utilized in data analytics for decision-making such as accident prevention and detection, controlling road risks, reducing traffic carbon emissions, and other applications which bring big data analytics into the picture

Charge. Point

The goal of this thesis is to reduce dependence on fossil fuels, lower the carbon emission footprint, and ignite a paradigm shift towards clean energy usage. Architecture can play a role in increasing the accessibility of sustainable modes of transit by changing the way energy is produced and distributed throughout the city. Accepting both the reliance and privatization of the automobile as givens, this idea caters to a transitional stage of travel, shifting from internal combustion engine vehicles to electric powered vehicles. Current technological limitations are stunting the momentum of a sustainable transit phenomenon, i.e. EV battery charge time and storage capacity, proximity of EVSE charging points to desired destinations and the capacity of the city grid to supply and distribute adequate amounts of energy. However by embracing these limitations as design objectives one can begin to develop ubiquitous charging points that not only provide reassurance against range anxiety but also brand an idea of clean energy. The typology will be self-sustaining in terms of energy through manipulation of its facade/exterior treatment. The nodes will create a positive urban experience, and common language through, signage, lighting, coloration, and surface treatment, that showcase a cultural commitment to the new technology. As 80%-90% of charging takes place at 1 home, these charging stations will focus on the other 10%-20% of charging that might occur in downtown lots, parking garages, on-street parking or highway stops. The nodes will feed energy to modes of public and private transit as well as acting as one of several pods within the city setting the stage for a self-organizing and adaptive networked phenomenon. Charge points will be connected to a media network interface closest vacant parking space. “A fundamental prerequisite for the major transport revolution we anticipate will be Challenging the conventional centralized single-sourced production and distribution of energy will allow for an interesting dynamic between production and consumer. As oppose to transporting energy from a power plant, energy will be locally produced directly from the architectural façade and into the vehicle creating a direct intersection between energies of the cities and the physical energy being consumed. The nodes will act as energy umbilici and when charging is not taking place, energy will be distributed back into the grid. In expanding and branding this typology of infrastructure as accessible, consistent and simple to use, EV’s will emerge as a viable option for drivers

Speculative animation: digital projections of urban past and future

This paper will explore the growing presence of digital animation within the work of contemporary visual artists, architects and designers concerned with urban geography. More precisely, it will examine how the use of digital animation has become a primary method for both envisioning alternative urban futures and reconstructing the traumatic past within socially and politically engaged work. In the context of urban speculation, digital animation has most often been used as a tool for visualizing large-scale, capital-intensive development plans. This is an animated future consisting of digital visualizations of high-end real-estate and populated by affluent, happy, racially homogeneous render ghosts. Alternatively, artists and designers have begun to employ similar software tools and digital animation techniques in order to re-potentialize the productive powers of the speculative. The paper will focus on four examples, two past and two future-oriented. The work of Eyal Weizman and the Forensic Architecture project has increasingly involved the use of digital animation techniques to both reconstruct and visualize key dates or events within moments of humanitarian crisis. In the Rafah: Black Friday case study, for example, digital animation and 3D modelling are used to reconstruct and present key events in a particularly intense four days of bombing during the 2014 Israeli military offensive in Gaza. The conceptual artist Stan Douglas has recently, and uncharacteristically, adopted digital animation and gaming technologies in his Circa 1948 collaboration with the NFB. The interactive app recreates a largely overlooked element of Vancouver’s past, the historical slum area of Hogan's Alley, notorious for its bootlegging, gambling and prostitution. The “speculative architect” Liam Young has been employing digital animation techniques to present urban scenarios that teeter between the utopian and dystopian. And finally, the artist Larissa Sansour merges live action and digital animation to visually depict bleak and disturbingly convincing Palestinian futures

Transformational urban landscapes: industry - infrastructure - logistics and the opportunity in shifts

The notion of city is altered and transformed more rapidly than ever before. Rather than extremely high densities, the repercussions of massive urbanisation is the decentralisation of industrial programs, infrastructures and resources, all of which are pushed out even further from the central city. The project examines the relationships between shifting industrial practices in the context of increasing urbanisation, centring on the symbiotic relationship between industry, infrastructure and logistics. The work focusses on logistic networks and the temporal, strategic and opportunistic transformations of the urban landscape that assert themselves on the collective form of the city. Through a series of writings, speculative experiments, and projects, the work seeks to accelerate the discontinuous density of change, integrating the existing milieu and future trajectories. The result is an amplification of relationships that are forged between both, interconnected and seemingly unrelated entities. The research identifies particular socio-economic conditions affecting the increments of contemporary urban development, and proposes a series of methods and interventions through which urban form can be reconstituted, and future change may occur. Instead of removal of industrial and replacement with residential, how might one propose a model of urbanism that can be created out of these activities in common, one that builds a new and complex urbanism from the different forces, and timelines, given the existing and new occupations of industrial inner-city sites

Algorithms for advance bandwidth reservation in media production networks

Media production generally requires many geographically distributed actors (e.g., production houses, broadcasters, advertisers) to exchange huge amounts of raw video and audio data. Traditional distribution techniques, such as dedicated point-to-point optical links, are highly inefficient in terms of installation time and cost. To improve efficiency, shared media production networks that connect all involved actors over a large geographical area, are currently being deployed. The traffic in such networks is often predictable, as the timing and bandwidth requirements of data transfers are generally known hours or even days in advance. As such, the use of advance bandwidth reservation (AR) can greatly increase resource utilization and cost efficiency. In this paper, we propose an Integer Linear Programming formulation of the bandwidth scheduling problem, which takes into account the specific characteristics of media production networks, is presented. Two novel optimization algorithms based on this model are thoroughly evaluated and compared by means of in-depth simulation results

Airport Territory as Interface: Mobile Work and Travel in Hybrid Space.

Premise In order to understand the future potential of work and air travel experience for constant travellers, design approaches from architecture and research methods from social studies should be combined. Abstract Global mobility, wireless technology and networked society are transforming the airport territory. These changes (hard factors) have been analysed in airport planning and transportation studies (Koll-Schretzenmayr 2003; Banister 2003; Schaafsma 2003; Knippenberger &Wall 2010; Salewski & Michaelli 2011; Convenz & Thierstein ed. 2014 et al) and architecture and design (Edwards 1998; Blow 2005; Cuadra 2002; Uffelen 2012; Gensler 2013 et al). But design strategies focusing on the passenger experience (soft factors) have not yet been thoroughly assimilated by architecture and design. On the theoretical level this dissertation spans the analysis of current methodologies in social studies (e.g. Castells 1996; Gottdiener 2000; Cresswell 2006; Urry, 2007; Elliott & Urry 2010; Adey 2010 et al) and their relation to architectural and urban studies concepts for the airport. The latter includes the “Airport as City” (Güller & Güller 2000), “Aviopolis – A Book about Airports” (Fuller & Harley 2005) and “Aerotropolis” (Kassarda 2010). This dissertation also explores IT and aviation industry interests at the interface between technology and air travellers. In this light aviation industry research and solutions (Amadeus 2011, SITA 2013) are important to consider, as well the philosophy behind who travels and for what purpose (Sloterdijk 1998; Koolhaas 1998; Gottdiener 2000; Urry 2007; Birtchnell & Caletrio 2014 et al). Here, the author’s previous field research at Frankfurt International Airport is relevant. We live more mobile lifestyles, we work in hybrid spaces (Suoza 2006; Duffy 2010 et al), and we consequently need to share information and collaborate differently. Using constant travellers as a case study, the impact of physical and informational mobility on perceptions of and behavioural patterns in the airport can lead to a deeper understanding of mobile work and the air travel experience. New design strategies can be developed from research about constant travellers, and the results may improve their work and air travel experience. The author’s combination of design approaches from architecture and social science (sociology and psychology) methodologies can better address the real needs of constant travellers in hybrid workspaces. It is hoped that this dissertation will inspire airport architects and designers, interaction designers and the aviation industry to pay more attention to users’ needs in their design processes

Content-aware : investigating tools, character & user behavior

Content—Aware serves as a platform for investigating structure, corruption, and visual interference in the context of present-day technologies. I use fragmentation, movement, repetition, and abstraction to interrogate current methods and tools for engaging with the built environment, here broadly conceived as the material, spatial, and cultural products of human labor. Physical and graphic spaces become grounds for testing visual hypotheses. By testing images and usurping image-making technologies, I challenge the fidelity of vision and representation. Rooted in active curiosity and a willingness to fully engage, I collaborate with digital tools, play with their edges, and build perceptual portholes. Through documentation and curation of visual experience, I expose and challenge a capitalist image infrastructure. I create, collect, and process images using smartphone cameras, screen recordings, and applications such as Shrub and Photoshop. These devices and programs, which have the capacity to produce visual smoothness and polish, also inherently engender repetition and fragmentation. The same set of tools used to perfect images is easily reoriented towards visual destabilization. Projects presented here are not meant to serve as literal translations, but rather as symbols or variables in experimental graphic communication strategies. Employing these strategies, I reveal the frames and tools through which we view the world. By exploring and exploiting the limitations of manmade technologies, I reveal the breadth of our human relationships with them, including those of creators, directors, users, and recipients
