The National Interoperability Field Operations Guide (NIFOG) is a technical reference for emergency communications planning and for radio technicians responsible for radios that will be used in disaster response. The NIFOG includes rules and regulations for use of nationwide and other interoperability channels, tables of frequencies and standard channel names, and other reference material, formatted as a pocket-sized guide for radio technicians to carry with them. If you are not familiar with interoperability and mutual aid communications, start with the How to Use the National Interoperability Field Operations Guide section.

A drive is an adjustable speed device that regulates the speed and direction of motors. Adjustment is done by varying the current flow through the motor. Drives are classified into two broad categories based on the type of current: AC drives and DC drives. AC drives are used to control AC electric motors, while DC drives are used for DC electric motors. Drives are widely used in manufacturing industries to regulate and control electrical devices such as fans,conveyors, machine spindles, and pumps. AC drives are widely used in process industries to increase the energy efficiency of motors.

This paper presents the results of an investigation of a proposed concept for closely spaced parallel runways called the Simplified Aircraft-based Paired Approach (SAPA). This procedure depends upon a new alerting algorithm called the Adjacent Landing Alerting System (ALAS). This study used both low fidelity and high fidelity simulations to validate the SAPA procedure and test the performance of the new alerting algorithm. The low fidelity simulation enabled a determination of minimum approach distance for the worst case over millions of scenarios. The high fidelity simulation enabled an accurate determination of timings and minimum approach distance in the presence of realistic trajectories, communication latencies, and total system error for 108 test cases. The SAPA procedure and the ALAS alerting algorithm were applied to the 750-ft parallel spacing (e.g., SFO 28L/28R) approach problem. With the SAPA procedure as defined in this paper, this study concludes that a 750-ft application does not appear to be feasible, but preliminary results for 1000-ft parallel runways look promising.

This report summarizes the results of Phase I (Design Concept) of an RDC effort to develop a readily deployable system for the in-situ detection, identification, and characterization of submerged oil in the water column. The first phase of the project involves development and testing of three technological approaches to the detection problem. A system developed by NORBIT US Ltd. addresses the detection of hydrocarbons using the backscatter from acoustic signals from a Wide Band Multi-Beam Sonar (WBMS). A system developed by WET Labs, named the Fluorescent IN-situ Detection System for OIL (FINDS OIL), uses flow-through fluorometric measurements and fluorescent backscatter to identify and characterize petroleum hydrocarbons encountered by the instrument. A third system, also by Wet Labs, named Wide-angle-scattering Inversion to Detect Oil in Water (WINDOW), uses the scattering and refraction of light to determine the mass and volume concentration, droplet size and density of the entrained oil. The systems are described in terms of the basic technology, ability to detect and characterize oil, areal coverage, ease of data processing and display, ruggedness and deployability, as well as the challenges involved in preparing the system for Prototype Development and Testing. This report will be used to make a decision on whether to move forward with prototype development for each system.

Independent Component Analysis (ICA) has largely been applied to the biomedical field over the past two decades and only recently extended to the processing of complex non-circular sources. The feasibility and performance of complex ICA to extract a weak co-channel interfering communications signal from a television broadcast signal is investigated in this thesis. The performance of three algorithms, complex maximization of non-Gaussianity (CMN) by Novey et al., RobustICA by Zarzoso et al., and complex fixed-point algorithm (CFPA) by Douglas, over varied interference-to-noise ratios (INR) for a fixed signal-to- interference ratio (SIR) is obtained by simulation. The communication signals examined for the weak interferer are binary phase-shift keying (BPSK), four- level rectangular quadrature amplitude modulation (4-QAM), and 16-level rectangular quadrature amplitude modulation (16-QAM), and the television broadcast signals are North American standard, Advanced Television Systems Committee (ATSC) and European standard, Digital Video Broadcasting - Terrestrial (DVB-T). Improved performance and sensitivity to the prewhitening step present in the ICA implementations are shown as the number of sensors increases.

Warfighting based on Commander s Intent and Mission Tactics will remain the foundation of command and control, but the information structure that supports Marine Corps tactical units will continuously undergo changes based on developments in information technology. Mobile Ad Hoc Networking is one of the information technology developments that the Marine Corps is currently studying. Mobile Ad Hoc Network s (MANETs) are infrastructureless, highly mobile communications and their multi-hop routing capabilities have the potential to reliably and robustly extend existing networks to the tactical edge. There are many challenges to MANET implementation however, including management of the dynamic physical topology, and the efficient use of limited spectral and energy resources. One platform being tested by the Marine Corps utilizes a time-division multiple access (TDMA) scheme combined with Barrage Relaying to ensure robust communications. Other schemes for MANETs employ intelligent-routing protocols. This thesis examines those protocols and identifies the parameters needed to implement a tactical MANET routing scheme. The findings of this research advance understanding of MANETs and the elements necessary to enable their use in support of tactical communications; bringing the Marine Corps closer to its goal of lightweight and efficient tactical communications.
