On October 12, 2000, terrorists bombed the USS Cole (DDG 67), an Arleigh Burke class destroyer. The vessel was in the process of receiving fuel while moored alongside a dolphin in the middle of the harbor at Aden, Yemen. With no local repair facilities and a tense diplomatic situation, the badly damaged, but stable vessel bad to leave Aden for repairs at another site. After a few intense days of weighing different options, handicapped with limited information, the Chief of Naval Operations (CNO) granted approval on October 14 to pursue a heavy lift operation. Two days later on October 16, the Navy awarded a contract voyage charter to heavy lift/dry transport the vessel to the United States on board a semi-submersible heavy lift ship. This paper will discuss a chronology of events and the associated engineering that culminated in the successful loading off the coast of Yemen and the safe transit home of this fully armed and badly-damaged warship. Detailed discussion will include the following: events leading up to the decision to heavy lift, preliminary engineering done in Oslo, Norway, detailed engineering done on board MV Blue Marlin, planning and execution of the loading operation, post loading and seafastening, the decision to fit a temporary patch, route planning, and the voyage home. The paper will also present the salient and unique characteristics of the Marlin class, currently the world's largest semi-submersible heavy lift ships.

The L − σ relation of HII galaxies (HIIGx) calibrated by a distance indicator is a reliable standard candle for measuring the Hubble constant H0. The most straightforward calibration technique anchors them with the first tier of distance ladders from the same galaxies. Recently another promising method that uses the cosmological model-independent Cosmic Chronometers (CC) as a calibrator has been proposed. We promote this technique by removing the assumptions about the cosmic flatness and using a non-parametric Artificial Neural Network for the data reconstruction process. We observe a correlation between the cosmic curvature density parameter and the slope of the L−σ relation, thereby improving the reliability of the calibration. Using the calibrated HIIGx Hubble diagram, we obtain a Type Ia Supernovae Hubble diagram free of the conventional assumption about H0. Finally we get a value of H0 = 65.9+3.0−2.9 km s−1 Mpc−1, which is compatible with latest Planck18 measurement. © 2022, CC BY.

Gaussian Process (GP) has gained much attention in cosmology due to its ability to reconstruct cosmological data in a model-independent manner. In this study, we compare two methods for GP kernel selection: Approximate Bayesian Computation (ABC) Rejection and nested sampling. We analyze three types of data: cosmic Chronometer data (CC), Type Ia Supernovae (SNIa), and Gamma Ray Burst (GRB), using five kernel functions. To evaluate the differences between kernel functions, we assess the strength of evidence using Bayes factors. Our results show that, for ABC Rejection, the Matérn kernel with ν=5/2 (M52 kernel) outperformes the commonly used Radial Basis Function (RBF) kernel in approximating all three datasets. Bayes factors indicate that the M52 kernel typically supports the observed data better than the RBF kernel, but with no clear advantage over other alternatives. However, nested sampling gives different results, with the M52 kernel losing its advantage. Nevertheless, Bayes factors indicate no significant dependence of the data on each kernel. © 2023, CC BY.

The "search for extraterrestrial intelligence" (SETI) commensal surveys aim to scan the sky to find possible technosignatures from the extraterrestrial intelligence (ETI). The mitigation of radio frequency interference (RFI) is an important step, especially for the most sensitive Five-hundred-meter Aperture Spherical radio Telescope (FAST), which can detect more weak RFI. In this paper, we propose several new techniques for RFI mitigation, and use our procedure to search for ETI signals from the archival data of FAST’s first SETI commensal survey. We detect the persistent narrowband RFI by setting a threshold of the signals’ sky separation, and detect the drifting RFI (and potentially other types of RFI) using the Hough transform. We also use the clustering algorithms to remove more RFI and select candidates. The results of our procedure are compared to the earlier work on the same FAST data. We find that our methods, though relatively simpler in computation, remove more RFI (99.9912% compared to 99.9063% in the earlier work), but preserve the simulated ETI signals except those (5.1%) severely affected by the RFI. We also report more interesting candidate signals, about a dozen of which are new candidates that are not previously reported. In addition, we find that the proposed Hough transform method, with suitable parameters, also has the potential to remove the broadband RFI. We conclude that our methods can effectively remove the vast majority of the RFI while preserving and finding the candidate signals that we are interested in. Copyright © 2023, The Authors.

Both the timely manufacture of defense systems and their subsequent on-line operability depend upon the availability of component parts. The growing problem of microelectronic component nonavailability is casting a shadow over logistics support to these systems. This paper will discuss the causes of the problem and provide some examples of cases confronted by the DoD logistics community. It will also identify some actions which have been taken in the past to manage the issue as well as initiatives now underway. Finally it will look at what lies ahead.

A research group at the Massachusetts institute of Technology has completed the first phase of the development of a computer assisted model for analyzing complex decisions and policies regarding oil spill cleanup. The model is the product of an ongoing MIT Sea Grant project, sponsored by a consortium of government and industry organizations, including the National Oceanic and Atmospheric Administration, the U.S. C oast G uard , the U.S. N avy , the Commonwealth of Massachusetts, the Spill control Association of America, JFB Scientific Corporation, the Doherty Foundation, Petro-Canada and Texaco. The model can be used, among other things, in strategic planning for the long-term oil spill response needs of a region, in assisting On Scene Coordinators in responding to a specific spill (tactical/operational setting), in evaluating the environmental and economic damages of a spill versus the cost of cleanup, in simulation and training, and in the analysis of various policy and regulatory issues such as the effects of delays, the use of dispersants and the investigation of liability and compensation issues. The paper describes the model in detail, focuses on its potential uses and presents experience with its application in conjunction with pollution control efforts of the U.S. Navy. Specifically, we outline the application of the model in the Port of Charleston, South Carolina, an ongoing project sponsored by the Naval Facilities engineering command. The difficulty of gathering data for such an application is discussed.

作者： GARRETT, JF HARDIE, RL ROGERS, PA Mr. James F. Garrett:is a staff engineer in the Systems Electromagnetic Division of the Naval Sea Systems Command (NAVSEA 61X4). He is Program Manager for the Shipboard Electromagnetic Compatability Improvement Program (SEMCIP) and for the Waterfront Corrective Action Program (WCAP). Mr. Garrett received his BS degree in Electrical Engineering from North Carolina A&T State University and his Masters of Business and Public Administration from Southeastern University. He is the originator and program manager of the NAVSEA EMI Control Program for Design and Acquisition. Mr. Robert L. Hardie Jr.:is a Project Manager with Scientific Management Associates Riverdale Maryland where he is presently managing and providing direct support to the Navy's EMI Control Program. He is also SMA's Deputy Project Manager supporting the Battleship Reactivation and Modernization Program. Mr. Hardie has been involved in Electromagnetic Environmental Effects for the last four years and Ship Acquisition Modernization and Conversion for the last fifteen years. He received his BS degree from Hampton Institute then served as Chief Electrical Engineering in the U.S. Army for two years. Mr. Paul A. Rogers:is a Program Manager with Scientific Management Associates and presently he is managing SMA's Management Support for a variety of programs including CG-47 High Performance Ships AALC LCAC Command Control Communications/Intelligence DDG-X and the Battleship Program. He has been involved in various aspects of Systems Acquisition for the past nineteen years.

As technical innovations in electronics have increased, piecemeal approaches to improving Electromagnetic Compatability (EMC) have resulted in overly complex and often ineffective designs. This paper addresses the current institutionalized approach to the reduction of management, planning and control deficiencies in the area of EMC. The paper begins with a discussion of the problems caused by EMI followed by a discussion of the traditional approach to reducing EMI. Then NAVSEA 61×4's role as the Electromagnetic Environmental Effects point of contact and as Electromagnetic Programs Coordination office is identified in the context of EMI control. The EMI/EMC Management benchmarks are also reviewed along with their appropriate management controls which ensure that all EMC planning for design, acquisition, modernization and conversion efforts are coordinated by the cognizant activities and program managers.

The hardwired point to point cabling that has been the mainstay of data handling on naval ships is slowly but surely giving way to more advanced techniques that include data bussing and high speed switching networks. The U.S. Navy's AN/USQ-82(V) Shipboard Data Multiplex System (SDMS) is now installed and operating for technical and operational evaluation purposes on USS Oldendorf , a DD 963 class destroyer. The distributed switching system “SITACS” introduced at ASNE Day 1982 has now been breadboarded. In the foreign arena, NATO standard bus and network interfaces are being implemented in Norwegian, United Kingdom and Canadian shipboard systems. These developments are reviewed, and projections are made regarding future trends in naval data handling systems.
