Authors:

The arrangements for dealing with Major Accidents in the United Kingdom are set out in the Health Circular (HC(77)1) which places the onus for planning on Health Districts—each district serving a population of no greater than 200,000. The Metropolitan Area of West Yorkshire, served by the West Yorkshire Metropolitan Ambulance Service, the West Yorkshire Metropolitan Police and the West Yorkshire Fire Service, takes in nine such districts and covers an area of 794,000 square miles and a population of just over two million. West Yorkshire is traversed by two motorways and a major trunk road.

Seepage through side slopes of small water impoundments

January 2008 · Geosynthetics International

An analysis was carried out on seepage through the side slopes of small water impoundments where only one geotextile was placed below the impermeable geomembrane. This study focuses on the characterisation of the flow associated with circular defects of small dimension. It was found that these types of defects produce reduced flow rates that are difficult to detect in service. Moreover, they may ...

As a result, although a lining system may appear to be efficient, in reality, a large part of the slope soil may undergo a substantial increase in water content.

An analysis of the emergency response system of the 1996 Channel tunnel fire

May 2017 · Tunnelling and Underground Space Technology

The paper presents the results of an analysis of the ‘emergency response system’ at the time of the 1996 Channel tunnel fire accident. In particular, the analysis focuses on the events that unfolded once the incident train had stopped; i.e., the evacuation of the passengers and the train crew. The approach has been the use of a ‘Tunnel Fire Safety Management System’ (‘TFSMS’) Model as a ... [Show full abstract] ‘template’ for comparison with the ‘emergency system’ in place at the time. In particular, responding to the following question being addressed: could the time of evacuation of the incident train crew and passengers be less that the time it took? The answer is Yes. Some relevant findings associated with the deficiencies in the existing 'system' have been highlighted by the model.

Experimental Study on Splashing During Liquid Jet Impingement Onto a Liquid Film

June 2016

A liquid jet is of considerable importance in many industrial fields including jet cleaning, jet engine and combustion. As an important example, the Monju nuclear power plant in Japan experienced a sodium leak in 1995. This led to a fire accident because the sodium reacted with oxygen in the air. To predict the significance of the fire accident, accurate evaluation of the amount of splashed ... [Show full abstract] droplets caused by the sodium jet impingement is of great importance. In this work, the relationship between the condition of a liquid jet and the amount of splashed droplets is explored experimentally. In the experiments, a liquid jet was emanated vertically downward from a circular nozzle onto a liquid film formed on a horizontal plate. Visualization using a high speed camera was performed to observe the condition of the liquid jet. From the nozzle, the mode of the liquid jet changed jet, lump and drop. Here, the jet mode means the continuous jet with smooth surface, the lump mode the continuous jet with disturbed surface and the drop mode the broken jet. Dependences of the transition length to each mode on the important parameters such as the jet velocity and the nozzle diameter were investigated. Measurement was also conducted for the splash ratio that is defined as the ratio of the amount of splashed droplets to the jet flow rate. It was found that the splash ratio is high when the liquid jet is in the drop mode at the impact point. It was shown that the splash ratio can be correlated well as a function of the impact Weber number and the Strouhal number of the droplets impinging the liquid film.

Thickness-Tapered Circular Plates-An Elastoplastic Large Deflection Analysis

January 1979 · Journal of Structural Mechanics

G.J. Turvey

A set of nonincremental equations describing the axisymmetric, elastoplastic, large deflection response of laterally loaded, thickness-tapered, circular plates is presented. The method of dynamic relaxation is proposed for its solution. A computer program based on this method is verified by comparison with test results. It is then used to carry out a limited parameter study on uniformly loaded ... [Show full abstract] plates with various taper ratios and support conditions. The data generated may be useful in the design of these plates— particularly in assessing the serviceability criterion of deflection.

Self-adjoint Extensions for Confined Electrons:from a Particle in a Spherical Cavity to the Hydrogen...

April 2012 · Annals of Physics

In a recent study of the self-adjoint extensions of the Hamiltonian of a particle confined to a finite region of space, in which we generalized the Heisenberg uncertainty relation to a finite volume, we encountered bound states localized at the wall of the cavity. In this paper, we study this situation in detail both for a free particle and for a hydrogen atom centered in a spherical cavity. For ... [Show full abstract] appropriate values of the self-adjoint extension parameter, the bound states lo calized at the wall resonate with the standard hydrogen bound states. We also examine the accidental symmetry generated by the Runge-Lenz vector, which is explicitly broken in a spherical cavity with general Robin boundary conditions. However, for specific radii of the confining sphere, a remnant of the accidental symmetry persists. The same is true for an electron moving on the surface of a finite circular cone, bound to its tip by a 1/r potential.

A mobile resource reservation mechanism with dynamic resourcesharing

February 2000

We propose and analyse an extension of the concept of RSVP to guarantee the service quality of mobile Internet-based applications. Our Mobile RSVP protocol provides an advanced resource reservation mechanism in a wireless cellular environment. Furthermore, we propose the dynamic resource sharing algorithm to make better use of network resources in those cells, where advance reservation takes ... [Show full abstract] place. We analyse our proposed protocol and the corresponding dynamic resource sharing algorithm by simulating the behaviour of distinct call types in a single cell. We also investigate the effect of user mobility behaviour on the performance of future resource reservation protocols with mobility support. By analysing the pattern of user mobility as well as possible application priorities, we hope to be able to put constraints to the scope of service provision

A simulation model of a helicopter ambulance service

January 2006 · Proceedings - Winter Simulation Conference

We study two different operational scenarios for a regional air ambulance service-company which has bases in northern California. Two of these bases serve the land areas encompassed roughly in a circular area of radius 100 miles centered in Gilroy and Salinas, respectively; with a large part of their coverage areas reachable from either base. The base in Salinas currently operates one helicopter ... [Show full abstract] only from Thursday to Monday, whereas the base in Gilroy operates one helicopter 24/7. The company is considering extending the operation of one helicopter to 24/7 for its Salinas base. In this paper we analyze the operational impacts of that extension, and develop a framework that can be applied towards the study of the ambulance assignment problem faced by small operators.

Mobility Over the Internet

Aharon Kellerman

Mobilities in both physical and virtual spaces, have received growing attention by contemporary scholars. The notion of cyber-mobility will be reviewed first, followed by discussions of the following specific notions, as for their relevance for Internet analysis: flow, speed, directionality, circularity, co-presence, and time-space compression. Internet co-presence evolves for all the four ... [Show full abstract] elements sought by individuals in space at large: fellow people, places, times and information. All the four elements, and the co-presence which they involve, will be presented in detail. Meaningful co-presence is not something that is just there, developing or occurring automatically, but it requires some activation by relevant Internet users.
