Additive manufacturing is steadily advancing towards fulfilling its promise of customized and on-demand production of functional parts. However, performance of as-manufactured parts can differ significantly from the as-designed parts because the as-manufactured geometry differs from the as-designed geometry and the asmanufactured material properties are not known. Attempts to predict performance o ...

The research involves implementation of a comparison algorithm for firearm forensics. The Congruent Matching Cells (CMC) algorithm and its associated CMF, CMPS, and CMX methods have been developed by NIST yet do not appear in any commercially available software. As requested in the call for proposals, we will implement the algorithms in the C++ programming language, we will validate their performa ...

The Next Generation Equipment Committee (NGEC) developed a standard for specifying the use of an Ethernet based digital train line (DTL) network to replace the COMM line for passenger trains. These specifications are PRIIA 305‐919 Digital Train Line Hardware and PRIIA 305‐920 Digital Train Line Software. The intent Is to eventually allow for the improvement of passenger train control. DTL spec ...

The research involves implementation of a comparison algorithm for firearm forensics. The Congruent Matching Cells (CMC) algorithm has been developed by NIST yet does not appear in any commercially available software. As requested in the call for proposals, we will implement the algorithm in the C++ programming language and validate CMC using two specified datasets. In addition, we will incorporat ...

U.S. DOT’s Zero Emissions Transportation Initiative is looking to push the transportation sector greenhouse gas production to zero by 2050. This solicitation/topic addresses alternative energy sources for the light vehicle, motorcycle, and bicycle sector. With the continuing significant development in commercialization and availability of biofuels, the possibility exists to meet this goal, with ...

This project seeks to define the performance requirements for a wireless Digital Train Line (WiDTL) through definition of functionality and performance expected, and translating these into network equipment specifications and architecture that wireless network equipment manufacturers can build towards. The effort will include an in-depth review of wireless technology as it applies to sensitive and ...

Autorack cars transport one of the most valuable commodities – fully assembled Automobiles. Due to the longer and higher profile of an Autorack and the fact that heavy automobiles are loaded on to high deck levels, freight trucks with improved track-to-vehicle dynamics as well as higher speed capabilities are desired in anticipation of higher speed passenger service and shared corridors. Unique ...

The goal of this project is to develop, prototype, and experimentally validate a new Differential Global Navigation Satellite System (DGNSS) capable of providing sub-centimeter positioning accuracy for quasi-static scientific, survey, and structural health monitoring application. The main feature of the proposed DGNSS solution is that it leverages publically available GNSS reference data from exis ...

The objective of the proposed work is to determine whether Dioxide Materials' miniature C02 sensors have the potential to be adapted for autonomous measurement of ocean carbon. The existing sensors have many advantages for measurements of ocean carbon. They are much smaller and less costly than the existing sensors, work with much smaller gas samples, and use much less power. The sensors were d ...
