A Better Bus Map: How Good Transit Map Design Can Strengthen the MBTA’s Bus System
(Massachusetts Institute of Technology, 2022-05)Greater Boston is poised to radically reimagine its bus system in the coming years. With an ongoing network redesign by the Massachusetts Bay Transportation Authority (MBTA) seeking to create a dense network of high frequency ... -
A Gear Hobbing Attachment for Manual Milling Machines to Facilitate the Production of Exotic Gears for Full-Scale Working Prototypes
(Massachusetts Institute of Technology, 2024-02)This thesis aims to present the design, development, and fabrication of a gear hobbing attachment tailored for manual milling machines. The primary objective is to create a versatile, cost-effective tool that streamlines ... -
A Low Cost Power Assist for Active Wheelchair Users
(Massachusetts Institute of Technology, 2023-06)Wheelchair power assists are devices that a wheelchair user may retrofit onto their wheelchair to increase their range, speed, and power. Users of these devices may already have the ability to propel themselves manually, ... -
A Microbial Survey of Lake Kivu: Mechanisms of Nitrogen Cycling
(Massachusetts Institute of Technology, 2023-06)Ocean Anoxic Events (OAEs) are periods in Earth’s history during which large por-tions of the oceans contain decreased amounts of oxygen. OAEs can be very difficult to study since modern oceans are generally well-oxygenated. ... -
A Percolation Model for Boiling and Predicting CHF
(Massachusetts Institute of Technology, 2022-05)Boiling is a ubiquitous process in numerous applications, characterized by the heat transfer coefficient (HTC) and critical heat flux (CHF). Exceeding CHF can result in catastrophic failure of a system, making it an important ... -
A Theoretical Exploration of the Growth and Stability of Alveolospheres
(Massachusetts Institute of Technology, 2022-05)An alveolosphere is a type of stem cell derived lung organoid. They have a distinct “balloon-like” structure which resembles the alveoli in human lungs. In recent years, they have become increasingly popular as model systems ... -
Abdominal vacuum lift as an aid to diagnosing abdominal adhesions
(Massachusetts Institute of Technology, 2006)The internal organs are designed to move freely and slide over one another during normal body movement. The abdominal organs, however, have a tendency to adhere to the abdominal cavity (peritoneum) and other abdominal ... -
Absolute pitch training.
(Massachusetts Institute of Technology, 1973) -
The absorption of nitrogen dioxide in concentrated nitric acid
(Massachusetts Institute of Technology, 1940) -
The absorption of sulfer dioxide in milk of lime
(Massachusetts Institute of Technology, 1944) -
Absorption studies of metastable helium atoms.
(Massachusetts Institute of Technology, 1966) -
Accelerated clustering through locality-sensitive hashing
(Massachusetts Institute of Technology, 2012)We obtain improved running times for two algorithms for clustering data: the expectation-maximization (EM) algorithm and Lloyd's algorithm. The EM algorithm is a heuristic for finding a mixture of k normal distributions ... -
An accelerated K[subscript ISCC] test for high-strength steels in hydrogen
(Massachusetts Institute of Technology, 1980) -
Accuracy control risk management for modular submarine hull construction
(Massachusetts Institute of Technology, 1999) -
An accurate analytical framework for computing fault-tolerance thresholds using the [[7,1,3]] quantum code
(Massachusetts Institute of Technology, 2005)In studies of the threshold for fault-tolerant quantum error-correction, it is generally assumed that the noise channel at all levels of error-correction is the depolarizing channel. The effects of this assumption on the ... -
The acetolysis of the p-toluenesulfonate of 9-hydroxymethyldianthracene
(Massachusetts Institute of Technology, 1960) -
Achieving quality of service guarantees on frame relay using weighted round-robin queueing
(Massachusetts Institute of Technology, 1998) -
Acoustic Method for Detection Large Pneumothoraxes in the Out-of-Hospital Environment
(Massachusetts Institute of Technology, 2023-06)Pneumothoraxes and hemothoraxes present a medical emergency that can easily be life threatening. However, improper and unnecessarily aggressive treatment is not uncommon and poses significant risk to patients. Much of this ... -
An acoustic study of the Blake transmitter
(Massachusetts Institute of Technology, 1891) -
