Abstract:

Impacts of meteoroids and space debris on pressure vessels can have detrimental consequences for any mission. Depending on the parameters of the impacting particle and the characteristic of the vessel, the damages can range from relatively uncritical craters in the vessel’s surface to the catastrophic bursting of vessels, which besides the loss of vessel may result in severe secondary damages to surrounding components. In order to investigate failure mechanisms of thin-walled aluminum pressure vessels under hypervelocity impact of space debris, a non-powder two-stage light gas gun was used to

Abstract:

The present paper summarizes the results obtained from impacts on shielded pressure vessels and analyzes the conditions under which bursting of a shielded pressure vessels occur that are damaged by space debris. The semianalytical model was generated to describe the processes occurring upon impact of a hypervelocity projectile into a shielded vessel. A model capable to describe the failure mechanisms of damaged vessels is suggested. Nonlinear fracture mechanics techniques were used to analyze and predict whether a vessel perforation will lead to mere leakage of gas, or whether unstable crack p

Abstract:

To achieve a modal shift towards waterborne transport and to deal with the shortage of crewmembers, a platooning concept called the “Vessel Train” is explored for the inland navigation sector. A Vessel Train consists of a lead and various follower vessels. The lead vessel is fully manned and takes over the navigational and situational awareness responsibilities for the follower vessels. This leading action benefits the followers through increasing the vessels’ productivity and enabling crew cost savings.

Abstract:

The length between perpendiculars (LBP) of most fishing vessels is less than 100 m. Thus, they are not subject to the International Maritime Organization (IMO) maneuverability standards, affecting research on maneuverability. However, upon referencing the statistics of marine accidents related to vessel maneuvering, the number of marine accidents caused by fishing vessels is 3 to 5 times higher than that of merchant ships. Therefore, systematic and consistent research on the maneuverability characteristics of fishing vessels is surely required. In particular, a fishing vessel frequently enters

Abstract:

Supernumery vessels are defined as presence of four or more vessels present within the umbilical cord. This condition may often accompany a poor pregnancy outcome and presence of congenital anomalies. They may be present in healthy fetuses. Chorangiosis is an adaptive response to in-utero hypoxia and its presence signifies better pregnancy outcomes. Abnormalities that lead to multiple cord vessels are rare with the majority of reported cases highlighting four vessels due to a persistent right umbilical vein.

Significant future growth is planned for the Port of Ngqura, but the Port does, however, suffer problems with moored container vessels. Under certain environmental conditions, these moored vessels experienced large motions, which lead to reduced operability or downtime and sometimes mooring line failures. One of the main contributing factors to the mooring problems is infra-gravity or long-waves (i.e. wave periods between approximately 25 s and 300 s), which induce basin and moored vessel resonance. A long-wave forecast system has been developed to assist the Port. Although this forecast syste

ABSTRACT Derelict vessels pose significant hazards to the communities in which they reside due to the cornucopia of oils and hazardous materials they contain including fuel oils, lubricating oils, lead-based paints, acid batteries, asbestos, and refrigerants like ammonia and Freon. Additional threats include attractions for children and vagrants, navigational hazards, and potential locations for illegally dumped oil or hazardous materials. The removal of derelict vessels is a complex undertaking due to restrictive legal authorities, ownership questions, high costs, and limited funding streams.

Abstract Loss of cognitive function with aging is a complex and poorly understood process. Recently, clinical research has linked the occurrence of cortical microinfarcts to cognitive decline. Cortical microinfarcts form following the occlusion of penetrating vessels and are considered to be restricted to the proximity of the occluded vessel. Whether and how such local events propagate and affect remote brain regions remain unknown.

Monumental artifacts belong to our cultural heritage, and there is a great need to protect them from earthquake damage. This study experimentally investigates the behavior of replicas of ancient vessels under seismic excitations. Each vessel was placed on a wooden base, which was attached to a shake table and was excited by earthquake signals. The effect of the amplitude of the excitation and the friction coefficient between the object and the base of support was examined. The dynamic response of the vessels included sliding and rocking, which, at high excitation levels, could involve rotation

Abstract:

In the Late Bronze Age settlement of Akrotiri on Thera stone vessels were imported, mainly from Crete, in parallel with local production which was in full swing at this time, as testified by the number and variety of products, especially those of everyday domestic use, that covered fully the needs of a large settlement. One group of stone vessels, which is characterised by the innovative character either of the shape or the combination of type and raw material used, includes products that cannot be attributed to known centres of stone vessel manufacture, such as those of Crete, Egypt and the S

Abstract:

The standard centrifuge method has been frequently used to measure vulnerability to xylem cavitation. This method has recently been questioned. It was hypothesized that open vessels lead to exponential vulnerability curves, which were thought to be indicative of measurement artifact. We tested this hypothesis in stems of olive (<em>Olea europea</em>) because its long vessels were recently claimed to produce a centrifuge artifact. We evaluated three predictions that followed from the open vessel artifact hypothesis: shorter stems, with more open vessels, would be more vulnerable than longer ste

Abstract:

Glaucoma, diabetic retinopathy, and macular degeneration can be identified by segmenting retinal  blood vessels. Glaucoma is most frequent and has serious ocular consequences that can even lead to blindness within these diseases. Intraocular pressure measurement, optic nerve head evaluation, retinal nerve fiber layer and visual field defects are the  diagnostic criteria for glaucoma include This form of blood vessel segmentation helps in early detection for ophthalmic diseases, and potentially reduces the risk of blindness.

Abstract Maritime vessel detection in infrared images at night faces challenges such as low contrast, target blurriness, occlusion, and small object sizes, which can lead to high rates of false positives and missed detection. We presented an enhanced algorithm integrating attention mechanisms and deformable convolution. First, the SE attention mechanism was employed to suppress noise interference in images, enhancing foreground targets attention, thereby effectively improving recall and reducing missed detection of target vessels.

AbstractThe UN Convention on the Law of the Sea contains (or makes reference to) many provisions about the investigation, detention and release of vessels. The detention and failure to release a vessel may lead to a dispute which could come before an international court or tribunal, in which case the release of the vessel on bail could be sought as an interim measure of protection (Art. 290). The special procedure for release contained in Article 292 is available only when it can be shown that the detaining state has not complied with the specific provisions of the Convention for the prompt re

Abstract:

Hidden aneurysms within occluded vessels present a challenge for interventionists because vessel perforation can lead to life-threatening complications. We present a case of middle cerebral artery ischemic stroke, refractory to thrombolysis. A direct aspiration first pass technique (ADAPT) was employed for revascularization. Following thrombectomy, an aneurysm of the occluded vessel was revealed. Despite this, the patient recovered without hemorrhagic complication. ADAPT permits the minimal insertion of endovascular devices and might be a safe procedure when hidden aneurysms are suspected.

Ship’s stability is one among the foremost important and complicated concept regarding ship and navigation’s safety and it's governed by maritime law as well as maritime codes. In Albanian bays, there has been considerable maritime tourism development in recent years, which has consequently brought about an increasing demand for passenger ships offering mainly one day cruises. The ships intended for this type of service are of different typologies: tourist vessels built especially for this destination, but there are many vessels which have changed the destination mainly from fishing vessel to

Abstract:

Blood flow in vessels is affected by several factors like vessel shape, blood thickness, and heart function. Swirling patterns of flow, called vortices, are often seen in blood vessels and can affect how blood flows. This study aims to understand how vortices affect blood flow and the reasons behind these changes. Different instruments, like particle image velocimetry (PIV), computational fluid dynamics (CFD), and magnetic resonance imaging (MRI), were used to measure and analyze blood flow. CFD simulations were done using realistic blood vessel models to study how vortices form and how they a

Many eye-related diseases will lead to blindness or worse when it is lack of treatment in the early stages of the disease. Retinal vessel is important for doctors to detect eye diseases, even though the increase of some thin vessels may also mean the occurrence of certain diseases. Therefore, automatic retinal vessel segmentation is of great help to doctors in diagnosing diseases. In this paper, an automatic vessel segmentation method is proposed for retinal image, which is based on support vector machine combining multi-scale feature fusion model and B-COSFIRE filter response.

The correct loading of bulk carriers is essential for their maritime safety. Inadequate loading can lead to various risks, including compromised hull strength, reduced stability and violation of the vessel's seaworthiness. Existing shipboard instruments do not allow for timely planning and real-time control of loading operations, which can lead to potential risks. The high intensity of loading operations at dry bulk terminals exacerbates the problem, as there is often insufficient time to adequately prepare and verify loading plans, increasing the risk of overloading cargo holds.

Abstract:

In offshore maintenance of oil platforms, a great number of technological processes on offshore fleet vessels (Diving Support Vessel, Construction Ship, Support and Supply Vessel) directly relate to the operation of flexible pipelines. Flexible pipelines are frequently used - from working fluids and fuel feeding to towing various surface and submersible craft. In some cases, in heavy seas, the flow velocities through the flexible pipeline can be very high. Ultimately, this will always lead to dangerous forced oscillations of the flexible pipeline that is used.
