SKY RECRE-ATIONAL HUB : RECLAIMING AIR SPACE ABOVE ECP EXPRESSWAY : RECONNECTING DISSECTED SPACES
… and there is great potential to utilize the air space above these highways to meet future needs. This thesis believes in a paradigm shift in treating infrastructure as separate from traditional land use. The site selected is along the ECP Expressway flanked by East Coast Park and Marine …

Air tight : polemics at the intersection of art, technology and the public domain
… democratically governed un-privatized public space. Historically, there is a legacy of artists working with techniques of dispersion, sequestering, and the visualization of otherwise imperceptible components of air to create meaning. Starting in the mid- 1960s, a number of artists and …

Automated identification of terminal area air traffic flows and weather related deviations
Air traffic in terminal air space is very complex, making it very difficult to identify air traffic flows. Finding air traffic flows and flow boundaries are very helpful in analyzing how air traffic would react to weather. This thesis created the Terminal Traffic Flow Identifier algorithm to solve …

Integration of Unmanned Aerial Systems in Class E Airspace: The Effect on Air Traffic Controller Workload
… needs to concentrate on the harsh truth of airspace safety. In the situation of integrating unmanned aerial systems (UASs) into the National airspace, UASs outside of terminal areas would generally be permitted to fly their preferred routes, and self-separate, with minimal intervention from …

Design and Implementation of Intelligent Guidance Algorithms for UAV Mission Protection
… fast prototyping and integration in the National Air Space (NAS). Many research efforts currently focus on system robustness against uncertainties but do not consider the probability of readjusting tasks based on the remaining resources to successfully complete the mission. In this thesis, an …

Observation and analysis of departure operations at Boston Logan International Airport
… analysis conducted at Boston Logan International Airport. It was observed that the departure process forms a complex interactive queuing system and is highly controlled by the air traffic controllers. Therefore, Flow constraints were identified with airport resources (runways, taxiways, ramp and …

Warship : memorial in antithesis
… epochs. In the second section I examine the aircraft carrier USS Intrepid Sea-Air-Space Museum of Patriotism, as a case study of how a contemporary memorial functions within and propagates a particular ideological agenda. This "living" memorial/museum works as a reminder of past threats to …

On-Board Artificial Intelligence for Failure Detection and Safe Trajectory Generation
… given that integration into the National Air Space (NAS) is becoming a primary need. However, the operational safety of these systems can be easily affected if abnormal flight conditions are present, thereby compromising the nominal bounds of design of the system's flight envelop and …

The relevance of delimitation debate in context of space tourism and space traffic management
… show that a legally accepted boundary between air space and outer space would effectively close the existing gap within air and space law which has led to uncertain legal application over space activities. Technology changes in aircraft, spacecraft, combined with the growth of space activity, …

ZeroN : mid-Air tangible interaction enabled by computer controlled magnetic levitation
This thesis presents a concept of mid-air tangible interaction and a system called ZeroN that was developed to enable this interaction. Through this research, I extend the tabletop tangible interaction modalities which have been confined to 2D surfaces into 3D space above the surface. Users are …

Development of an Airport Choice Model for General Aviation Operations
The General Aviation Airport Choice model is an attempt to model General Aviation (GA) travel patterns in the US in order to provide a means of assessing the impact of General Aviation activities on the National Air Space system. The model will also serve as part of transportation planning tool to …

Studies of Lung Micromechanics via Hyperpolarized 3He Diffusion NMR
… MR investigations of the lung's more abundant air space rather than its tissue. In addition to high-resolution images of lung ventilation, lung morphometry via gas diffusion NMR provides information about the size and shape of the microscopic airways that account for over 95% of the lung's …

An investigation of electromagnetic rig-generated strong magnetic fields
… two alternative solenoid designs are presented: 'Air-core' coil design and 'C-shape' coil design. The coils were designed to be capable of generating strong and static magnetic fields in various samples of magnetic materials. In the case of the first design, the sample would be placed in the …

The city village : a design for public and semi-public places and paths in a residential and office community in Cambridge, Massachusetts
… that the separation of living and working spaces is no longer a necessity. Telecommunications, new technologies, non-industrial and non-noxious industries are changing the nature of the workplace and allowing its integration into residential neighborhoods. The influx of independent …

A Heuristic Approach to Solve Air Taxi Scheduling Problem
… in any one time period is insufficient to meet air travel demanded, it may be expected that some unfilled demand passengers will either delay their flight or will advance it, thus adding to the effective demand of the adjoining time periods.The obvious alternate means of travel is a rental car. …

Planning service facilities and infrastructures under continuous traffic equilibrium
… found in many contexts that involve a continuous space. Personal air vehicles (i.e., ``flying cars'' that can take off and land ``outside of a house or in a garden'') are being considered as an option to allow future travelers to utilize low-altitude air space. The freight industry (e.g., Amazon, …

Mathematical optimization methods for aircraft conflict resolution in air traffic control
Air traffic control is a very dynamic and heavy constrained environment where many decisions need to be taken over short periods of time and in the context of uncertainty. Adopting automation under such circumstances can be a crucial initiative to reduce controller workload and improve airspace …

Creating sustainable air rights development over highway corridors : lessons from the Massachusetts Turnpike in Boston
Research and practice have shown that air rights development over highway corridors in America's cities is not only feasible, but desirable. As planners, policy makers and consumers attempt to curb the sprawling development pattern that was characteristic of the second half of the twentieth …

Duality derived topological model of single phase four limb transformers for GIC and DC bias studies
… of the core and stray flux in the surrounding air space when the transformer saturates. Three phase testing is included using a three phase bank of test transformers. The electrical measurements of waveforms are analysed and fast Fourier transforms carried out to obtain the harmonic components. …
