Inland waterways form a natural network that is an existing, congestion free infrastructure with capacity for more traffic. The European commission promotes the transportation of goods by ship as it is a reliable, efficient and environmental friendly way of transport. A bottleneck for transportation over water are the locks that manage the water level. The lockmaster’s problem concerns the opti...

EXTENDED ABSTRACT Commercial marine vessels range in size from small fishing boats (20-30 meters in length) to extremely large tanker ships (>300 meters in length). These ships almost without exception use diesel engines for propulsion and auxiliary power generation. The larger ships, comprising bulk carriers, tankers and container carriers, utilize slow-speed diesel (SSD) engines that produce ...

This paper considers collision and grounding of passenger ships. Subsequent to a collision or grounding, there might be water ingress into the compartments and the risk of sinking exists. In such circumstances, timely and effective evacuation of all passengers and crew will be extremely important, and failure to evacuate in time may lead to catastrophic consequences. This paper presents probabi...

OBJECTIVES To determine the accuracy of (1) hospital discharge data and (2) death certificates, coded as motor neuron disease (MND). DESIGN Comparison of data from The Scottish Motor Neuron Disease Register (SMNDR) with routinely collected Scottish Hospital In-Patient Statistics (SHIPS) and death certificate coding. SETTING Scotland UK. PATIENTS 1) 379 adults (> 15 years) discharged for t...

that the quantum fluctuations of an electromagnetic field, so-called zero-point fluctuations, give rise to an attractive force between objects 1. This force is a particularly striking consequence of the quantum theory of electrodynamics (for a review, see ref. 2). Casimir's calculations were idealized — he considered two perfectly conducting parallel plates at absolute-zero temperature — but th...

Gondwana landmasses have served as large-scale biogeographic Noah's Arks and Beached Viking Funeral Ships, as defined by McKenna. The latitudinal trajectories of selected Gondwana dinosaur localities were traced through time in order to evaluate their movement through climate zones relative to those in which they originally formed. The dispersal of fauna during the breakup of Gondwana may have ...

This paper scrutinizes the common belief that electric vessels are economically unadvantageous. To achieve this, data of most known all-electric cargo ships (available in internet as 2021) was gathered and missing information estimated with due diligence, to put together a sample selection. Sample vessels’ parameters including principal dimensions, speed battery capacity were used calculate the...

In 1998, the United States sought and received International Maritime Organization-endorsement of two Mandatory Ship Reporting (MSR) systems designed to improve mariner awareness about averting ship collisions with the endangered North Atlantic right whale (Eubalaena glacialis). Vessel collisions are a serious threat to the right whale and the program was among the first formal attempts to redu...
