Optimal operation of internal combustion engines requires careful regulation of the fuel and air in the combustion chamber. Engine valves are the vital component of this regulation as they adjust the flow across the inlet and exhaust ports. The conventional approach is to use mechanically driven camshafts to actuate the intake and exhaust valves. The motion of the valve is controlled by a fixed cam profile to ensure the soft landing of valves, minimal noise and long life. As every engine with a camshaft uses a single profile, the timing of the valve with respect to piston motion is fixed for all speed and load conditions. Thus, the selection of cam profile today involves a restrictive trade-off between fuel economy, engine performance, emissions and noise.

This restriction can be overcome if fully variable electronically controlled valve timings are deployed that depend on engine demand conditions. Fully variable valve timing is sometimes referred to as camless engines, Lotus Engineering’s patented Active Valve Train (AVT) system being a specific example.

ParOS, with the support of the UK Department of Trade and Industry Global Watch Secondment Scheme, developed a model-based controller for the electronic regulation of the research (AVT) system at Lotus Engineering. The scheme is an output feedback predictive optimizing controller that was derived off-line using parametric programming techniques. The controller was tuned for a range of given valve profiles and tested experimentally.

If you are lacking a binding machine in your home, don’t worry, there are several options that you can use to properly bind your documents safely and securely in place. While a binding machine is a great thing to have, many start up business or people working from home might not have the funds to buy a binder right away. Some of the reasons for this might seem obvious (i.e. putting together school assignments) while others might surprise you (i.e. it can be affordable). That said, let’s take a look at some of the reasons why you should consider getting a binding machine for home use.

* When you think of binding machines, a device that utilizes plastic combs probably comes to mind. Combs are really popular supplies because they’re easy to work with and can bind both short and long books. However, there are other bookbinding types to choose from such as thermal and wire. So feel free to select one that appeals to you.
* One reason you should consider getting a binding machine is that they’re actually surprisingly affordable. You can usually get a high-quality unit from some of the most popular manufacturers (GBC, Fellowes) for under $100.00. (A thermal machine will probably cost a bit more than that.) No matter what your budget is like, there’s likely a device that’s right for you.
* Many binding machines are easy to use so you can start producing quality work rather quickly. Some of them are designed in such a way that you can figure out how to use one without even reading an instruction manual.
* A binding machine is a great tool to have around if you or someone you live with is attending school. You can use it to bind items such as theses, term papers, essays, and so on. You could even use it to bind group presentations. A bound document can really impress your teacher or professor and it could be that one thing that raises from your grade from a B to an A. (A caveat: you may want to make sure your teacher will accept a bound document. Some of them prefer papers that have just been stapled.)
* If you dabble in cooking or photography, you might want to make a cookbook or photo album at some point. These items can help you organize and store your favorite recipes or photos for easy reference. You could also give away cookbooks as gifts or sell them at a crafts fair. And if you need to put together a portfolio of your best photographs, the binding machine can help you out. It will even help you save money because you don’t need to have a third party do the work for you.
* Finally, binding machines can be handy if you’re interested in crafting. For one thing, they make it possible for you to create your own scrapbooks. You can use your own special paper to create a book that’s really personal. You could also make coloring books, art collections, and so on. The sky’s the limit.

As you can see, there are many reasons to get a binding machine for home use. Consider getting one today so you can see how useful it can be.
