Abstract:
The article focuses on the functional capabilities, technical characteristics and bench composition of the laboratory of ship auxiliary mechanisms, which was created at the Department of Operation of Water Transport at the Astrakhan State Technical University (ASTU) for training marine engineers. The laboratory provides the students with professional competencies in such aspects of the mechanical engineer’s operation as ship turbo machines, ship auxiliary mechanisms and systems, automatic control systems, operation of ship boiler rooms and steam generating plants, etc. There have been presented the pictures of laboratory test benches for testing the P01 ship steering machine and ЯШ-2Р anchor mooring pin, РCC-6.3/10 ship fan, TKР-700 turbo compressor, gear fuel pump Ш5-25-3Б, prototypes of TГ-16M gas turbine generator and ГTД-16M gas turbine engine. Using the laboratory test benches for auxiliary mechanisms and systems helps to both consolidate the theory and gain the new practical knowledge on the design, operation principles and testing skills of the ship steering machine, deck equipment, ventilation systems gear pumps, turbochargers, etc. It has been stated that all the laboratory facilities, except for the GD-IN model (facilities for studying the pump operation and constructing pressure-flow characteristics), were developed and assembled by the students and teachers on the basis of the real ship equipment. The laboratory tests are based on regulatory and technical documents: the rules of the Russian Maritime Register of Shipping, machine operating instructions, relevant GOSTs, guidance and regulatory documents. Building the laboratory of auxiliary mechanisms and systems and optimizing the time for practical and laboratory training of ship mechanical engineers at ASTU were carried out in accordance with the requirements of the new educational standard GEF 3++ of higher education and the International Convention on Training and Certification of Sailors and Watchkeeping (The Manila amendments to the STCW Convention and Code).

Abstract:
In order to ensure the safety of the staff and the property of our laboratory, and guarantee the ship/bridge crash test conducted safely and smoothly, we adopt the safety monitoring system to supervise the whole ship/bridge crash testing laboratory and to be early warning, under the background of special application of ship/bridge crash testing laboratory. According to the actual site of crash testing laboratory, we choose the most suitable technology and operating principle to satisfy the request of ship/bridge crash testing laboratory. At the case that we do not need to increase the number of camera excessively, we can achieve the maximum coverage of the field of view by choosing the multi-function camera and designing the layout of it, and we will take advantage of the broadcasting alarm system to reach the purpose of keeping the safety of our laboratory. The results of actual application show that the staffs in the monitoring room can take the whole laboratory under their controls if we make use of this kind of safety monitoring system of ship/bridge crash testing laboratory, and we can fully protect the safety of the staff and the property of our laboratory. For the pretty good stableness and capacity of resisting disturbance, the system can greatly satisfy the request of keeping safety and early alarm.

There is short in the number of large ship handling simulator and it has high failure in BRM training. They could not remain for a long time in the laboratory for teachers qualified with captain and highly educated full-time laboratory personnel. Marine institutions begin to carry out practical teaching reform for these problems, which make people to work hand with policy support and scientific and rational evaluation mechanisms, innovative training teaching methods and establish an objective assessment criteria. By BRM training students enhance the ship's emergency response, role awareness and situational awareness, which have important practical significance to enhance navigational safety and strengthen risk awareness.

Abstract:
The work presented in this article is the result of collaboration between historians and computer scientists whose goal was the digital reconstitution of Le Boullongne, an 18th-century merchant ship of La Compagnie des Indes orientales.1 This ship has now disappeared and its reconstitution aims at understanding onboard living conditions. Three distinct research laboratories have participated in this project so far. The first, a department of naval history, worked on historical documents, especially the logbooks describing all traveling events of the ship. The second, a research laboratory in archaeology, archaeoscience, and history, proposed a 3D model of the ship based on the original naval architectural plans. The third, a computer science research laboratory, implemented a simulation of the ship sailing in virtual reality.

Abstract:
Abstract Magnetic resonance imaging (MRI) yields numerous tumor-related incidental findings (IFs) which may trigger diagnostics such as biopsies. To clarify these effects, we studied how whole-body MRI IF disclosure in a population-based cohort affected biopsy frequency and the detection of malignancies. Laboratory disclosures were also assessed. Data from 6753 participants in the Study of Health in Pomerania (SHIP) examined between 2008 and 2012 were utilized. All underwent laboratory examinations and 3371 (49.9%) a whole-body MRI. Electronic biopsy reports from 2002 to 2017 were linked to participants and assigned to outcome categories. Biopsy frequency 2 years pre- and post-SHIP was investigated using generalized estimating equations with a negative-binomial distribution. Overall 8208 IFs (laboratory findings outside reference limits: 6839; MRI: 1369) were disclosed to 4707 participants; 2271 biopsy reports belonged to 1200 participants (17.8%). Of these, 938 biopsies occurred pre-SHIP; 1333 post-SHIP (event rate/100 observation years = 6.9 [95% CI 6.5; 7.4]; 9.9 [9.3; 10.4]). Age, cancer history, recent hospitalization, female sex, and IF disclosure were associated with higher biopsy rates. Nonmalignant biopsy results increased more in participants with disclosures (post-/pre-SHIP rate ratio 1.39 [95% CI 1.22; 1.58]) than without (1.09 [95% CI 0.85; 1.38]). Malignant biopsy results were more frequent post-SHIP (rate ratio 1.74 [95% CI 1.27; 2.42]). Biopsies increased after participation in a population-based cohort study with MRI and laboratory IF disclosure. Most biopsies resulted in no findings and few malignancies were diagnosed, indicating potential overtesting and overdiagnosis. A more restrictive policy regarding IF disclosure from research findings is required.

Abstract:
SUMMARY Antimicrobial stewardship is a bundle of integrated interventions employed to optimize the use of antimicrobials in health care settings. While infectious-disease-trained physicians, with clinical pharmacists, are considered the main leaders of antimicrobial stewardship programs, clinical microbiologists can play a key role in these programs. This review is intended to provide a comprehensive discussion of the different components of antimicrobial stewardship in which microbiology laboratories and clinical microbiologists can make significant contributions, including cumulative antimicrobial susceptibility reports, enhanced culture and susceptibility reports, guidance in the preanalytic phase, rapid diagnostic test availability, provider education, and alert and surveillance systems. In reviewing this material, we emphasize how the rapid, and especially the recent, evolution of clinical microbiology has reinforced the importance of clinical microbiologists' collaboration with antimicrobial stewardship programs.

Abstract:
L'émission dans l'atmosphère de nanoparticules issues des transports préoccupe la communauté scientifique à cause de leurs impacts probables sur le changement climatique. La compréhension de l'effet de ces émissions sur l'environnement reste faible principalement à cause du manque de données expérimentales sur la caractérisation de ces nanoparticules. Ce travail est axé sur les propriétés physico-chimiques des nanoparticules de combustion et sur leur interaction avec l'eau. L'hydroscopicité est l'un des paramètres déterminants liés à la formation des noyaux de condensation des nuages (NCN). Les données expérimentales montrent des différences dans la microstructure, la composition chimique et la morphologie des suies de laboratoire et des résidus émis par les transports. Les quantités d'eau absorbées sur la suie de chambre de combustion de moteur d'avion et sur les résidus issus de la combustion de fioul lourd et de diesel sont bien plus importantes que sur les suies de laboratoire. Nous pouvons ainsi supposer que ces particules agissent comme des noyaux actifs dans la formation des NCN
Transport emission of nanoparticles into atmosphere is of major interest because of its possible effect on climate changes. The understanding of the potential environmental effect of the aviation and ship emission is still poor maintly because of the lack in the experimental characterization of these nanoparticules. The present work focuses on physico-chemical properties of combustion nanoparticles and their interaction with water. Hygroscopicity is on of the key parameters that are related to could condensation nuclei (CCN) activity and the environnemental effect. Experimental data show differences in the microstructure, elemental composition residuals coming from marine transport emitted residuals. Water uptake on combustion residuals coming from marine transport and aviation is higher than for laboratory-produced samples. We can therfore guess that these particules act as active CCN in the atmosphere

Abstract:
This study was conducted to ascertain the impacts of bed leveling, following ship channel dredging operations, and to also investigate the hydrodynamic flow field around box bed levelers. Laboratory experiments were conducted with bed levelers operating in the laboratory using video cameras for flow visualization. Computer software and numerical codes, called FANS, were used to validate the laboratory experiments. The study was split into two major parts: laboratory experiments and hydrodynamic modeling. The laboratory experiment was conducted to model how bed levelers interact with the ship channel bottom after hopper dredge dragheads (blades) made passes and created uneven trenches. These interactions were observed using both underwater and hand-held cameras. The hydrodynamic modeling was accomplished using GRIDGEN and PEGSUS commercial software for generating grid and input data files in the pre-processing phase, Finite-Analytic Navier-Stokes (FANS) software for simulation in the processing phase, and two commercial software (Fieldview and Tecplot) for plotting the images and graphs in the post-processing phase. An interesting phenomenon was observed in the laboratory experimental runs. The flow field showed reversed flow in front of the moving bed leveler and the trench parallel to the direction of the bed leveler. The flow in the parallel trench was observed to be in the same direction as the bed leveler movement, and it was expected that the flow would travel under the bed leveler. The bed leveler was towed at two specified constant speeds: 0.25 m/s (0.82 ft/s) and 0.5 m/s (1.64 ft/s) and at a water depth of 1.22 m (4.00 ft) Similarly, the images and plots of the hydrodynamic modeling obtained from FieldView and Tecplot software showed flow reversal, depicted by the negative velocities, within the vicinity of the trench, as the model bed leveler moved past and interacted with the fluid. The negative velocity had a magnitude close to 0.5 m/s (1.64 ft/s), which was the velocity used in running the laboratory experiments. The hydrodynamic simulation matched closely with the experimental observations, and thus, the laboratory observation was confirmed. The final results obtained from the numerical modeling helped to understand the hydrodynamic effects around the box bed leveler.

Abstract:
Knowledge about the level of damage after a collision with an ice mass is necessary for designing ships and offshore structures operating in ice-infested waters. An understanding of the physical processes during such a collision is needed to prevent (or limit) accidents, causing loss of life, the loss of a ship or environmental pollution. This study was motivated by the lack of experimental data on ship collisions with ice masses where both the ship and the structure undergo deformations. Laboratory experiments of accidental collisions with ice masses (ACIM) are essential to verify current methods for integrated analysis of the crushing and deformation of the ice and the steel structure. ACIM tests are sensitive to the structural design, i.e., the design of a structure that is flexible enough in relation to the ice mass. Both the ice and the structure should be able to deform during the collision event. The paper addresses issues related to the planning of ACIM at laboratory scale with special emphasis on the choice of: (i) process of ice manufacturing and ice mechanical properties; (ii) flexibility of impacted structure; (iii) scaling of the experiment. Experimental setup of laboratory-scale ACIM for the Aalto Ice Tank is proposed. Non-linear finite element analysis is used as a tool to predict structural damage and to guide the planning of collision experiments. The predicted damage of the test specimens caused by collision is presented.

Abstract:
To investigate the ability of numerical models to simulate the behavior of moored ships subjected by ship-wake waves, use is made of scale model tests where a ship model sails with constant speed along a straight path at a constant distance from an otherwise motionless ship. The tests were carried out at one of the wave tanks of the Portuguese Civil Engineering Laboratory (LNEC). The moving ship is a self-propelled scale model of the “Aurora” chemical ship whereas the otherwise motionless ship is a scale model of the “Esso Osaka” tanker. The free-surface elevation was measured with a set of resistive wave gauges and ADVs. The tanker’s movements, induced by the wake waves, were measured along the six degrees of freedom with a gyroscope deployed inside the ship. The numerical model WAMIT provides, in the frequency domain, the quantities required to estimate the hydrodynamic forces associated to the interaction of a free-floating ship with waves. The BAS model uses those hydrodynamic forces to study in the time domain the ship interaction with any sea-waves acting on it. Wind and current actions can also be accounted for. The results of these numerical models are compared to the measurements made in the several repeats of one of those scale-model tests, in terms of the response amplitude to several wave components. These comparisons enabled the evaluation and validation of the numerical models parameters’ calibration process.

Full text
Abstract:
Ship motion instabilities occur much more frequently in coastal regions than in the deep ocean because both nonlinear wave-wave interactions and wave-current interactions increase significantly as the water depth decreases. This is particularly significant in the coastal regions connecting to the open ocean, since the wave resonant interactions change from the four-equivalent-wave interaction in deep water to the interactions of three local wind waves with a long wave (e.g. swell, edge waves, bottom topography waves, etc.) in shallow water [1, 2], resulting in rapid growth of the incoming long waves. In this study, we use our DiSSEL (Digital, Self-consistent, Ship Experimental Laboratory) Ship Motion Model [3,4,5,6] coupled with our Coastal Wave Model [1,2,11] and an Ocean Circulation Model [7] to simulate strongly nonlinear ship motions in coastal regions, focusing on the ship motion instabilities arising from ship body-surface wave-current interactions.

Abstract:
Put simply, ‘spoofing’ is a means of controlling the reported position and time of a GNSS receiver. Spoofing has now been well demonstrated in the experimental context, but until a few years ago it was regarded as “…a bit like UFOs: much speculation, occasional alarms at suspected instances, but little real-world evidence of its existence” (Ref. 1). In the intervening years spoofing has transformed from a research laboratory into an emerging threat. In this paper we focus on radio-frequency attack as the primary method of spoofing. However there is also the possibility of cyber-attack on GNSS systems, in which there is interception and modification of computed position between the receiver and application. It had perhaps previously been considered that the technology and know-how “barrier to entry” to produce an effective spoofer was itself a significant deterrent. However, the commercial availability of inexpensive (sub £250) software defined radio systems, low-cost computing and open-source GNSS signal generator software has all but eliminated this barrier. This paper will consider various methods of spoofing, means of detecting spoofing through analysis of signal anomalies and also mitigation of spoofing at the physical layer via the antenna and signal processing and at the software application layer through the detection of anomalies.

Abstract:
The Houston Ship Channel is one of the busiest deep -draft navigation channels in the United States and must be able to accommodate larger vessel dimensions over time. The U.S. Army Engineer District, Galveston (SWG) requested the U.S. Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory perform hydrodynamic and sediment modeling of proposed modifications along the Houston Ship Channel. The modeling results are necessary to provide data for salinity and sediment transport analysis a s well as ship simulation studies. SWG provided a project alternative that includes channel widening, deepening, and bend easing. After initial analysis, two additional channel widths in the bay portion of the Houston Ship Channel were requested for testing. The results of these additional channel widths are presented in this report. The model shows that the salinity does not vary significantly due to the channel modifications being considered for this project. Changes in salinity are 2 parts per thousand or less. The tidal prism increases by less than 2% when the project is included, and the tidal amplitudes increase by no more than 0.01 meter. The residual velocity vectors do vary in and around areas where project modifications are made.

Abstract:
The Houston Ship Channel (HSC) is one of the busiest deep-draft navigation channels in the United States and must be able to accommodate increasing vessel sizes. The US Army Engineer District, Galveston (SWG), requested the Engineer Research and Development Center, Coastal and Hydraulics Laboratory, perform hydrodynamic and sediment modeling of proposed modifications in Galveston and Trinity Bays and along the HSC. The modeling results are necessary to provide data for hydrodynamic, salinity, and sediment transport analysis. SWG provided three project alternatives that include closing Rollover Pass, Bay Aquatic Beneficial Use System cells, Bird Islands, and HSC modifications. These alternatives and a Base (existing condition) will be simulated for present (2029) and future (2079) conditions. The results of these alternatives/conditions as compared to the Base are presented in this report. The model shows that the mean salinity varies by 2–3 ppt due to the HSC channel modifications and by approximately 5 ppt in the area of East Bay due to the closure of Rollover Pass. The tidal prism increases by 2.5% to 5% in the alternatives. The tidal amplitudes change by less than 0.01 m. The residual velocity vectors vary in and around areas where project modifications are made.

Abstract:
The Brunswick area consists of many acres of estuarine and marsh environments. The US Army Corps of Engineers District, Savannah, requested that the US Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory, develop a validated Adaptive Hydraulics model and assist in using it to perform hydrodynamic modeling of proposed navigation channel modifications. The modeling results are necessary to provide data for ship simulation. The model setup and validation are presented here.
