Diagenetic Controls on Hydrothermal Fluid Flow in the Osiris, Isis, and Isis East Carlin-Type Gold Showings, Nadaleen Trend, Yukon
DownloadFall 2015
Following ATAC Resources Ltd.’s 2010 discovery of the gold prospects in the Nadaleen Trend (Central Yukon), company geologists and consultants determined that Precambrian carbonate rocks within the trend contain large endowments of gold located in the hinges of anticlines and fault zones. ...

Effects of Negative Valve Overlap on HCCI Combustion and its use in the Control of HCCI Combustion Timing
DownloadFall 2014
Homogeneous charge compression ignition (HCCI) combustion can produce higher efficiencies and lower emissions when compared to tradition spark or compression ignition engines. This study reports an experimental investigation into the effects of valve timings on HCCI combustion conditions. Using a...

An experimental single cylinder engine with variable valve timing is used to study spark ignition and homogeneous charge compression ignition (HCCI). The discrete wavelet transform, on a single cylinder engine with a cam-phasing head, is used in real time for knock detection in HCCI. Classical...

A dual-fuel system is used to control HCCI combustion timing and load in a CFR engine. The systems steady-state response to iso-octane and n-heptane injected energy is investigated then a dynamic ARMAX model is found using system identification. This model is used to design a norm-optimal...

Lithium Recovery from Hydraulic Fracturing Flowback and Produced Water using a Manganese-Based Sorbent
DownloadFall 2020
Increased demand for lithium products for use in lithium ion batteries has led to a search for new lithium resources in recent years in order to meet projected future consumption. One such potential lithium resource is low lithium bearing brines that are discharged from hydraulically fractured...
