Optically transparent, thermally insulating and soundproofing (OTTIS) aerogel for high-efficiency window applications
(Massachusetts Institute of Technology, 2020)
Building heating, ventilation and air conditioning (HVAC) accounts for about 13.6 quadrillion BTU ("quads") per year or 14% of the total energy consumption in the United States.' Accounting for 39% of annual US carbon ...
Microfluidic and electronic detection of protein biomarkers
(Massachusetts Institute of Technology, 2020)
Proteins are essential components of our bodies and play critical roles in biological processes. Quantifying protein levels can help characterize these biological processes and detect malfunctions. Thus, protein testing ...
A second generation URANS approach for application to aerodynamic design and optimization in the automotive industry
(Massachusetts Institute of Technology, 2020)
In the U.S., transportation is responsible for approximately 70% of all petroleum consumption and is now the largest source of carbon emissions and air pollution. Aerodynamics is an important aspect for energy saving and ...
Performance and economics of monovalent selective electrodialysis desalination for irrigation
(Massachusetts Institute of Technology, 2021)
Reverse osmosis (RO) is the most widely used desalination technology for the treatment of irrigation source water and wastewater. Brackish groundwater, seawater, and agricultural effluent often contain both monovalent ions ...
Design and optimization of shared mobility on demand : dynamic routing and dynamic pricing
(Massachusetts Institute of Technology, 2021)
Mobility of people and goods has been critical to urban life ever since cities emerged thousands of years ago. With the ushering in Cyber-Physical Systems enabled by the development of smart mobile devices, telecommunication ...
Computational processing and modeling of intravascular images precisely couple arterial morphology and biomechanics
(Massachusetts Institute of Technology, 2021)
Cardiovascular diseases, and coronary artery disease in particular, remain a persistent devastating and prevalent menace to health and wellbeing globally despite great strides in vascular biology and medicine. While ...
Towards security by design of connected and automated vehicles : cyber and physical threats, mitigations, and architectures
(Massachusetts Institute of Technology, 2021)
Security, safety and privacy converge when it comes to the design of cyber-physical systems (CPS) such as connected and automated vehicles (CAVs). This trend can be attributed to the increased level of connectivity and ...
Introducing perovskites to the IoT world using photovoltaic-powered ID tags
(Massachusetts Institute of Technology, 2020)
Billions of everyday objects could benefit from being augmented with sensors and wireless data transmitters. The prospect of developing advanced battery-powered sensors and smart devices with on-board radio and computing ...
Aero-thermal-mechanical interactions in ultra high-speed micro gas turbines
(Massachusetts Institute of Technology, 2020)
Aero-thermal induced mechanical response of engine components in an ultra high-speed micro gas turbine engine system is assessed. Scaling down gas turbine engines for high performance requirement dictates substantial ...
Dynamic marketing policies : constructing Markov states for reinforcement learning
(Massachusetts Institute of Technology, 2020)
Many firms want to target their customers with a sequence of marketing actions, rather than just a single action. We interpret sequential targeting problems as a Markov Decision Process (MDP), which can be solved using a ...
