What could we do with a 20-meter tower on the Lunar South Pole? Applications of the Multifunctional Expandable Lunar Lite & Tall Tower (MELLTT)
Summary
Summary
Lunar polar regions and permanently shadowed regions (PSRs) are a key component of NASA's exploration objectives for the lunar surface, given their potential for a high abundance of volatiles like water. The Massachusetts Institute of Technology (MIT) Big Idea Challenge Team proposed the use of deployable towers to support robotic...
Antennas and RF components designed with graded index composite materials
Summary
Summary
Antennas and RF components in general, can greatly benefit with the recent development of low-loss 3D print graded index materials. The additional degrees of freedom provided by graded index materials can result in the design of antennas and other RF components with superior performance than currently available designs based on...
Graded index dielectric superstrate for phased array scan compensation
Summary
Adjoint analysis of guidance systems for time-series inputs using Fourier analysis
Summary
Summary
The adjoint technique is a proven technique for analysis of linear time-varying systems and is widely used in the missile design community. It is a very efficient technique that can solve for both deterministic and stochastic disturbances and can develop a miss distance budget in a single computer solution of...
A hands-on middle-school robotics software program at MIT
Summary
Summary
Robotics competitions at the high school level attract a large number of students across the world. However, there is little emphasis on leveraging robotics to get middle school students excited about pursuing STEM education. In this paper, we describe a new program that targets middle school students in a local...
CW radar operation in the focused near-field

Simulation approach to sensor placement using Unity3D
Summary
Summary
3D game simulation engines have demonstrated utility in the areas of training, scientific analysis, and knowledge solicitation. This paper will make the case for the use of 3D game simulation engines in the field of sensor placement optimization. Our study used a series of parallel simulations in the Unity3D simulation...
Human-machine collaborative optimization via apprenticeship scheduling
Summary
Summary
Coordinating agents to complete a set of tasks with intercoupled temporal and resource constraints is computationally challenging, yet human domain experts can solve these difficult scheduling problems using paradigms learned through years of apprenticeship. A process for manually codifying this domain knowledge within a computational framework is necessary to scale...
Modeling and validation of a mm-wave shaped dielectric lens antenna
Summary
Peregrine: 3-D network localization and navigation
Summary
Summary
Location-aware devices will create new services and applications in emerging fields such as autonomous driving, smart cities, and the Internet of Things. Many existing localization systems rely on anchors such as satellites at known positions which broadcast radio signals. However, such signals may be blocked by obstacles, corrupted by multipath...
