Calibration of Jicamarca radar using F-region incoherent scatter for measurements of D-region backscatter RCS
This thesis presents calibrated radar measurements of absolute backscatter cross sections of mesospheric radar echoes observed at the Jicamarca Radio Observatory in Perú. Radar system calibration is accomplished by simulating the propagation of transmitted and backscattered radio waves through the …

An Enhanced RCS Heuristic and an Enhanced RCPM Algorithm to Perform Delay Analysis in Schedules without Phantom Float
… after applying resource-constrained scheduling (RCS) methodologies. RCS techniques solve the resource conflicts but create phantom float in the schedules (i.e., a float that does not exist). RCS techniques overlook the resources relationships between activities that compete for the same but …

Manipulation of antenna-mode radar cross-section in patch antennas
The Radar Cross-Section (RCS) of an antenna has two main components: structural RCS and antenna-mode RCS. Structural RCS is due to the physical geometry of the antenna. The antenna-mode RCS component is due to load impedance mismatches and can be manipulated by changing the load impedance connected …

Rapid FTIR analysis for respirable crystalline silica monitoring in coal mines using readily available sampling equipment
… conjunction with respirable crystalline silica (RCS). Overexposure can pose serious health risks, including development of coal workers' pneumoconiosis (CWP) (also known as "black lung"). CWP has the potential to progress to a more consequential form known as progressive massive fibrosis (PMF), …

The syntax and processing of relative clauses in Mandarin Chinese
… thesis investigates relative clauses (henceforth RCs) in Mandarin Chinese as spoken in Taiwan from both syntactic and processing perspectives. I also explore the interaction between these two areas, for example, how evidence from one area lends support to or undermines theories in the other area. …

Analytical methods to investigate occupational exposure to toxic elements and their species
… chromium and respirable crystalline silica (RCS). Current biological monitoring methods are either no longer deemed fit for purpose (arsenic), not ideal (chromium) or are not available (RCS). The limitations of occupational exposure assessment of hexavalent chromium and RCS are linked to the …

Physical and Biologic Properties of Calcium Silicate Endodontic Sealers
… solubility of Endosequence BC Sealer, BioRoot RCS, NeoSEALER Flo, and BIO-C SEALER. MATERIALS AND METHODS: Nuclei counting assay and MTT assay were used to determine the cytotoxicity of the sealers at dilutions of 1:1, 1:4, and 1:32 and at 24 hours, 72 hours, and 1 week. Vickers microhardness …

Structural and functional relationship of photosynthetic bacterial reaction centers
The structure of reaction centers (RCs) was modified with various sulfhydryl reagents. It was found that mercurial reagents, especially p-chloromercuribenzenesulfate (pCMBS), inhibit Q$\sb{\rm B}$ function in RCs from Rhodobacter sphaeroides and Rhodobacter capsulatus, but not in Rhodopseudomonas …

Detection and characterization of deep water wave breaking using moderate incidence angle microwave backscatter from the sea surface
… angle measurements of the radar cross-section (RCS) and Doppler spectrum. Specifically, breaking events have been associated with polarization independent sea spikes in the RCS accompanied by increased mean frequency and bandwidth of the Doppler spectrum. Simultaneous microwave, video, and …

A Resource-constrained CPM (RCPM) Scheduling and Control Technique with Multiple Calendars
… (CPM) and Resource-Constrained Scheduling (RCS) techniques. A traditional CPM schedule is not realistic since it assumes unlimited resources, some of which are highly limited in practice. Although traditional RCS techniques can consider resource limitations, they do not provide correct …

Comparison of guided endodontic access with and without pin fixation in 3D printed teeth with simulated pulp canal obliteration
… treat an infected root canal system (RCS), it is required to locate all root canals and have an access path to the apex of each canal. This can be challenging in teeth with pulp canal obliteration (PCO), often leading to increased chair time and increased risk of iatrogenic errors. …
