HS2 is good for the national economy and will create jobs in the engineering and technology sector.

Against:
HS2 won't solve Britain's commuter problems and the money should be invested in digital infrastructure.

The argument for:
Good infrastructure is essential to the success of a competitive modern economy. That's why countries around the world are investing in high-speed rail - helping businesses by bringing cities closer together. More and more people in Britain are travelling by train, and demand continues to climb. Unless we invest and plan for the future, our rail network risks becoming a brake on economic growth. That is why we are planning a high-speed rail network that will link eight of Britain's ten biggest cities. High Speed Two is a once-in-a-generation opportunity to invest in Britain's future by making space for people and freight on our increasingly crowded railways.

The argument against:
HS2 is the highly controversial proposed high-speed rail link between London, Birmingham, Manchester and Leeds. The first trains between London and Birmingham won't carry passengers until 2026 and the second phase from Birmingham northwards is due for completion in 2033. It's a government project, meaning the taxpayer will pay the cost of construction, but the benefits are uncertain. The HS2 tracks are estimated to cost £33bn and a further £8bn for the trains. Stop HS2 thinks that HS2 is a bad project in its own right. But there are also much better ways of achieving the same goals.

A new airport to the east of London is the best option for proper expansion.

Against:
A new airport to the east of London is not the best option for proper expansion.

The argument for:
Britain needs at least a four-runway airport. That cannot be achieved through the redevelopment of the Heathrow site to the west of London. A new site to the east has some real advantages in terms of ease of construction, relatively unconstrained operation and opportunities for economic growth and development on the eastern side of the capital. Starting with a cleared site means that you can design it to be one of the great airports of the world. In terms of surface access it could connect into London with both high-speed links and the local links necessary to get staff to the airport from a wide surrounding area.

There is still a role for Heathrow as a small airport. The opportunities for developing the site as it became available through a reduction in capacity would generate significant economic returns and job opportunities for West London. I hate the phrase, but I think it is a 'win-win scenario' for the capital and an opportunity for Britain to step up to being the leading aviation country in Europe.

The argument against:
West London Business (WLB), the Chamber of Commerce for West London, represents over 600 businesses in the area. Were an alternative hub airport to be built elsewhere, the effect on the west London economy would be little short of catastrophic. Lessons learnt from failed experiments with two hubs - in Canada and Japan - show that an economy the size of the UK's is only able to support one hub airport, so an alternative would mean Heathrow closing or seriously downsizing.

Heathrow is central to west London's £37bn economy. Not only is it a major source of employment, it attracts inward investment and holds international business here. Some 46 per cent of jobs at the airport are filled by people from the surrounding five boroughs. It is unrealistic to assume that all of these people would uproot their families and move to the Thames Estuary. WLB believes that the lack of a credible financial plan, together with a lack of social and environmental cost analysis, and the negative impact on West London and the Thames Valley, renders the Thames Estuary alternative unrealistic and unnecessary.]]> http://www.theiet.org/forums/forum/messageview.cfm?catid=227&threadid=50813 2013-02-09T18:52:41 00 centaur 1 http://www.theiet.org/forums/forum/messageview.cfm?catid=227&threadid=50704 2013-02-05T12:36:12 00 eviejones 1 http://www.theiet.org/forums/forum/messageview.cfm?catid=227&threadid=50701 2013-02-05T08:28:19 00 cjmyerscough 1 1900 Monday (1900 Monday) leave home

There are also other inconsistencies. Both my newer cars have low profile wider tyres and have tyre wear rates worse than any previously owned vehicles. They also both make hugely larger amounts of road noise. These are both indications of more energy being wasted - not less, not to mention the greater amount of particulate generation from the lost tyre rubber. Particularly the diesel car I own weighs a more than the previous one even if the interior is smaller. Once agin this is going to decrease the efficiency of the modern vehicle.

The most beneficial feature of the hybrid car is that it does not create pollution and thus is great for environment as it uses the power from the engine to get started and then to keep the car running they use stored electricity created by battery packs which are stored in the trunks. Honda and Toyota are the leaders to use hybrid technology and to introduce hybrid cars. But almost every car manufacturer is using this technology. The reason that hybrid cars are becoming more popular is that they are not only fuel efficient, but also less harmful to the environment.]]> http://www.theiet.org/forums/forum/messageview.cfm?catid=227&threadid=48983 2012-10-30T12:20:04 00 Fatmir 1

Call deadline extended to June 30th

The Integrated Applications Promotion (IAP) programme of the European Space Agency (ESA) is inviting public and commercial end-user organisations to propose ideas and suggestions for new services in Critical Infrastructure as defined below. The aim is to generate ideas leading to services that will improve business performance and operations, help enforce new regulatory standards, or enable improved resilience.
The ideas will be used to help define and consolidate requirements for user-driven services supported through the IAP programme.

Full details of the Call and on how to submit your ideas online or to download the offline form can be found at:
http://iap.esa.int/opportuniti...e-call-for-user-ideas
You can also download a MS-Word version of the User Response application form template and email it to: iap@esa.int, putting "Critical Infrastructure" in the subject heading.
Your ideas and suggestions should reach us by 30th June 2012.

Critical Infrastructures

Critical Infrastructures can be defined as those handling essential goods (e.g. water, energy, food, confidential information) and/or services (e.g. health, financial transactions or resilience services). Infrastructures are critical when they represent key enablers in a large variety of economic sectors. Loss or damage of critical infrastructure would have a severe and widespread impact, e.g. disruption of supplies or services, injury or loss of human lives, risks to or destruction of the environment, breach of national security or economic interests.

Criticality is also determined by the level of endangerment the infrastructure is subject to, and by its vulnerability to such hazards. Infrastructures are particularly exposed to hazards when physically spread out, e.g. linear infrastructures such as pipelines. Hazards can be diffuse (e.g. low intensity hazards affecting infrastructure over a long period of time) or acute (e.g. sudden attacks, accidents, natural hazards). They can also be predictable (e.g. corrosion) or unpredictable (e.g. tsunami or terrorist attack).

Hazards to critical infrastructure need not only be physical. For instance, cyber attacks may damage internet-linked control systems that are related to critical infrastructures such as the electrical grid, water treatment facilities, refineries, pipelines and dams.

Critical infrastructures are most often man-made, such as power plants or airports. Yet they can also be natural. For example, wetlands are a natural infrastructure that store water and thereby mitigate floods.

Critical infrastructures typically enable the production, processing, transportation, storage or protection of essential goods, as well as the provision of basic services such as:

Water (e.g. water pipes, treatment plants, water towers, dykes, dams, canals).
Food (e.g. roads, warehouses, ports).
Energy (e.g. pipelines, refineries, energy grids, power plants).
Confidential or critically sensitive information (e.g. telecommunication infrastructure).
Health and well-being (e.g. hospitals, waste treatment plants).
Environmental protection (e.g. pollution prevention, CO2 storage).

Call for User Ideas

Themes that it is intended to cover in this Call for User Ideas include (but are not restricted to):

Mitigation: Deployment of protective systems to prevent damage or disruption by resilience to hazards. For mitigation of cyber attacks this should include encryption techniques and other methods.
Preparedness: Monitoring conditions and taking preventive actions, e.g. identification, monitoring & quantification of hazards, vulnerability and risks; infrastructure health monitoring; preventive maintenance.
Response: Activation of emergency spare capacity to satisfy peak demand, or to back-up failed infrastructure, e.g. space telecommunications as a back-up communications infrastructure.
Recovery: Supporting strategies minimising the propagation of negative effects caused after disruption such as evacuation of people and emergency repairs, and help in the assessment of damage caused to or by disrupted infrastructure.

How to participate?

The Call for User Ideas on Critical Infrastructure is driven purely by the users' perspective and their needs. The ideas submitted will be used to help define and consolidate themes and priorities of future IAP projects. This may include both Feasibility Studies (through Open Competitions or Direct Negotiation), or directly through Demonstration Projects.

There's obviously nothing wrong with the workers & engineers, because with foreign management and investment it is clearly going very well. Companies like Nissan, Honda, Ford, BMW, Volkswagen & Tata are happy with their investments in the UK.

I would like to ask why are linear motors not being considered for mainstream use on main rail lines. If there was a linear motor system then you would not need to maintain vast amounts of cabling above electrified railway lines.
A major improvement would be that linear motors could be switch on only when a train passes over the motor, which is a big energy saving to take into consideration in relation to overhead cables which need a constant energy supply.
The could be cost saving over constructing and maintaining overhead cabling.
In terms of health and safety the linear motors look to be a safer option than overhead power cables because they would be switched of until a train passes over them unlike overhead power cables that are on all the time.

Why is there not any implementation of linear motor systems on main lines? Is there something that I have overlooked in my argument?

Eventually, the vision is that cars in the future through electronics and nano technology, will become autonomous and communicate with themselves via a wireless network and radio communication (or another method) and be able to drive you to your destination through using intelligent vehicle technologies while you relax. Hmm, I don't know if I feel so secure putting my full trust in my car to get me home quite yet.

Although these systems help to make the car more efficient and reliable, reduce C02 (Carbon Dioxide) emissions and meet many government laws around the world, they also create other problems, which we sometimes forget about.

I would like to have ISA by drivers. But this is sometimes difficult on unfamiliar roads with poor speed-limit signing, and none of us is a perfect driver.

I would love to have my satnav device give me a warning when I drift over the local speed limit, or I miss a sign that is behind a tree.
I would love my satnav to take speed limits into account when plotting routes.

All of these things are impossible until we have a down-loadable electronic roadmap of UK speed limits.

Since governments have not responded to the 2002 recommendation of the Transport Select Committee, alternative methods may be needed.
One way to achieve it would be for all of us to verify local speed limit data in the OpenStreetMap www.openstreetmap.org.

This does not absolve the driver from thinking, because the database is Open. But it could be a step in the right direction.

The project is slated to be running by 2026, long after vast swathes of the working population are working and meeting using Telepresence systems and avoiding travel altogether.
The proposed line opens up no new routes, connects no new population centres and solves none of the current classic rail network issues.
The business case for HS2 is slowly being pulled apart and the cost of the project out of all proportion to the benefit.
Only 8% of car journeys are over 25 miles, and the majority of flights from UK airports are long haul. HS2 will, therefore, take few cars off the road and few flights out of the air.

The Farnborough International Air Show has an attendance of approximately 130,000 on the trade days and a similar number on the Family days. There was in 2010 a "Futures Day" when schools are encouraged to attend which had a potentially 5,000 students in attendance.
A dession needs to be taken now so that the appropriate budgetary cover can be agreed in line with the IET Bugetary Cycle

I believe that to portray the IET and the Aerospace Network as an effective Global Network it should have a presence at the Farnborough International Aerospace Show in July 2012.
This could show the totality of the IET Knowledgebase

The IET did have a stand at DSEi in London on one occassion , DSEi has an attendance of about 25,000, a quarter of the Farnborough attendance

The RAeS have, at previous shows, had a large stand but I would suggest that the IET could look at being hosted in the NWAA complex which would be more cost effective. This was look at for the 2010 show but not in the correct timescale.

Support for the Stand could be covered by volunteers as well as IET Staff.

I am about to embark on a new career contracting as an electronic engineer. My previous experience has been within the military and I have been carrying out electronic maintenance for 12 years.

I have been offered a contract recently which requires me to work on an aircrafts power distribution system.

I hasten to add that I will be working on the manufacturer's side at the factory and won't be touching aircraft in anyway.

My understanding of the role is that defective systems are returned to my client who then pass it onto their team (myself included) to diagnose, report, repair and test. As I haven't yet started work I don't know exactly how involved I will be in the repair and test loop and what safeguards my client will have in place to prevent any mistakes having serious consequencies. Obviously though there will be rigourous procedures in place to prevent this hapening!

As a contractor I have set myself up as a Private Limited Company and the Agency who set me on are asking that I get Prfoessional Indemnity Insurance to the value of £1m and herein lies the problem. I understand the general need for this cover but when I approach any insurer they hear the words aviation or aircraft and they run a mile or quote figures which seem unreasonable to me (in the region of £2000)

With the broad depth of knowledge amongst these forums I wondered if anyone would have any experience of obtaining PI Insurance in the aviation world, if they could recommend a broker who won't run a mile at the word "Aircraft" or who might be able to offer advice. (I realise the insurance and Aviation Industries are heavily regulated but any tips or advice would be welcomed)

Thanks for reading.

In the railways we use "slugged" relays, but never slugged circuit boards!
All joking aside (as there was a fatality) what are the views on the transport/safety forums regarding this. It is not explicit, but it can be deduced that the failure caused the lights to go off and that was a cause in the accident.
My question is, it is normal practice in the railways to coat circuit boards with a "conformal coating" to protect against damp etc. (not come across slug trails before though!) what is the practice in the Highways area? Also, what sort of SIL (according to IEC61508) are traffic light controllers designed to.

Cheers

Can someone please explain why small fault currents flow when there is a single earth fault on an IT circuit. I undertsand it is linked with capacitive coupling. Can anyone please explain whay this happens?

Thank you!

Forgive my ignorance, but I've got a small issue to think about and would like to consult with someone more intelligent. Namely - inertial force for a descending plane. Let's assume, that a 80-ton plane is descending during landing procedure with the vertical speed 11 m/s and a pilot wants to rapidly level the flight trajectory. Let's assume that he is able to do in one second, what means that the plane stops descending and levels the trajectory in 11 meters (let's leave for a moment feasibility of such manoeuvre aside). That gives us nice vertical deceleration 11 m/s^2 and therefore 1.1 G(x)-force (g = 11/9.81). Accordingly, inertial force (F =-(ma)) to overcome with such manoeuvre would be 8800000 N or 8800 kN what leads to conclusion, that the generated by the plane lift should have this enormous value. In this simply calculation I don't take into account all stuff as lift-drag ratio, aerodynamic drag and so on. Is this calculation correct, or I'm going haywire?

Problem 1: You're driving around the city centre looking for an available parking space; your mobile phone application only tells you where the nearest car parks are, not on-street parking. What you'd like is for the mobile phone application to tell you exactly where the nearest parking SPACE is; how much it costs to park there; and more importantly, if it's empty.

Problem 2: You're in a car park, you've taken your ticket from the machine, now you need to find an available space. What you'd really like is for the car park to tell you where the nearest available space is, rather than you having to go round and round searching for one.

I know there has been a system implemented at Heathrow Terminal 5, but it's very costly and I doubt that you would be able to "upgrade" existing car parks to that level.

Benefits: If an application could be developed to solve these problems, it would actually create some significant benefits:

1. Time saved for the Driver
2. Fuel saved by the Driver
2. Less Traffic
4. Less Road Rage

There are then consequential benefits for City Councils and the Environment, with less traffic, means less congestion and less pollution.

From my initial research, this kind of major project would require the involvement and collaboration with Local Councils, database information for on-street parking spaces; mobile phone software developers and hardware developers to provide sensors to detect parking space availability.

I know a similar system is already undergoing trials in San Francisco, but I just wanted to find out if anything similiar was being developed in the UK?

Many thanks.

I am also representing the IET on this Steering Group, so I would be interested to receive feedback from anyone who is trying to get started using TRAK, has thoughts about how it should evolve, or generally has something to say regarding architectural modelling in the railway industry.

I encourage all railway systems engineers to take a look at TRAK at TRAK Community. Give it a try. I am convinced there is value in an interchangeable modelling framework for the railway industry.

To contact me, just send a private message on here with your contact details and I'll get in touch.]]> http://www.theiet.org/forums/forum/messageview.cfm?catid=227&threadid=37003 2010-08-05T07:29:03 00 akyadav 3

I am doing a report and I need some information on how many installed kilometres each of the majow equipment suppliers have. For example on the London Metro Siemens equipment is installed with ......km or Network rail has .......km installed from INvensys.

I would be really appreciative if anyone has any information or knows of where they can point me to find some information]]>
