Significant Flood Events

Many experts are forecasting an increase in weather related disasters. The effects of global warming are becoming more obvious and changes in weather patterns may be related to this.

In the united States hurricanes are the most destructive weather related events. Major hurricanes usually result in major flood damage. The year 2005 was the worst year for flood damage in recent history. FEMA generally considers a significant flood event to be when 1,500 losses are paid in a single event. In 2005 FEMA rated 5 hurricane related events in the significant event category. An event with a billion dollars paid in FEMA flood claims would be considered as especially large.

FEMA flood losses paid for hurricane Katrina were in excess of 15 billion dollars. The actual damages were far greater because many homes and business did not have flood coverage. Total damages are estimated at over 80 billion dollars. In addition to economic damages more than 1,800 people lost their lives in hurricane Katrina and in related floods. The effects of damage and impacted lives from this storm will linger for years.

There is a list of major flood events available at www.Texas-Flood-Insurance.com/floodevent.html.

There will certainly be hurricane and flooding events in the future. The government and individuals are making efforts to be better prepared for future events. There has been a lot of good information for individuals on how to prepare for a major storm and or flooding. One lesson from recent flooding is that many people overlook flood insurance. Homeowners insurance doesnt cover flooding and it is necessary to get a separate policy if you want flood coverage. Most flood policys are backed by the federal government and the cost is very reasonable.

There Is A Battle For Ligimate Fat Burner Programs

It's a fact - 95% of the people who go on conventional diets gain all the weight back and sometimes they end up fatter than when they started.

When you mention bodybuilders, some people think of steroids or fat burning drugs. It's sad but true - most pro bodybuilders take them. But the joke's on them. drugs work, but the results are temporary and the side effects are nasty. The tiny handful of bodybuilders who have learned how to use training and nutrition science to alter body composition without drugs are the only people in the world who keep their fat loss and muscle gains permanently.

When I started Tom's Burn The Fat diet program in January, I weighed 317 pounds. As of Dec. 1st, I weigh 226 lbs. 91 pounds of fat gone forever is a pretty cool thing! And by the way... I turned 40 this year, so if anyone out there is thinking that you are "too old" - think again.

Chris Brooke, Marietta, GA

When I started the program in September, I was 248 pounds with 24% bodyfat. With Tom's information, I have been able to lose 43 pounds - all of it fat. My body fat is now 12%. I also no longer spend $400 a month on supplements.

Jerry McBride, Philadelphia, PA

It doesn't matter what your goals are: most of the principles are the same whether you want to lose 10 pounds or 100 pounds; whether you want to be 13% body fat or 3% body fat; whether you want to compete in a bodybuilding or fitness show or you just want to look good in a shorts and a tank top. Whatever your goals, when you finally decide to stop making the same mistakes that have been holding you back and you diligently begin applying the techniques in Burn the Fat Feed the Muscle, you can literally choose any body you want!

How Do PID Controllers Work: Application & Theory

What is a PID controller?

A PID (Proportional Integral Derivative) controller is a common instrument used in industrial control applications. A PID controller can be used for regulation of speed, temperature, flow, pressure and other process variables. Field mounted PID controllers can be placed close to the sensor or the control regulation device and be monitored centrally using a SCADA system.

Example: Temperature control using a Digital PID controller

A typical PID temperature controller application could be to continuously vary a regulator which can alter a process temperature. This may be a pulsed switching device for electrical heaters or by opening and closing a gas valve. A heat only PID temperature controller uses a reverse output action, i.e. more power is applied when the temperature is below the setpoint and less power when above. PID control for injection and extrusion applications often employ additional cooling control outputs and usually require multiple controllers.

A PID controller (sometimes called a three term controller) reads the sensor signal, normally from a thermocouple or RTD, and converts the measurement to engineering units e.g. Degrees C. It then subtracts the measurement from a desired setpoint to determine an error.

The error is acted upon by the three (P, I & D) terms simultaneously:

PID controller Theory

The following section examines PID controller theory and provides further explanation of the question `how do PID controllers work'.

Proportional (Gain)

The error is multiplied by a negative (for reverse action) proportional constant P, and added to the current output. P represents the band over which a controller's output is proportional to the error of the system. E.g. for a heater, a controller with a proportional band of 10 deg C and a setpoint of 100 deg C would have an output of 100% up to 90 deg C, 50% at 95 Deg C and 10% at 99 deg C. If the temperature overshoots the setpoint value, the heating power would be cut back further. Proportional only control can provide a stable process temperature but there will always be an error between the required setpoint and the actual process temperature.

Integral (Reset)

The error is integrated (averaged) over a period of time, and then multiplied by a constant I, and added to the current control output. I represents the steady state error of the system and will remove setpoint / measured value errors. For many applications Proportional + Integral control will be satisfactory with good stability and at the desired setpoint.

Derivative (Rate)

The rate of change of the error is calculated with respect to time, multiplied by another constant D, and added to the output. The derivative term is used to determine a controller's response to a change or disturbance of the process temperature (e.g. opening an oven door). The larger the derivative term, the more rapidly the controller will respond to changes in the process value.

Tuning of PID controller Terms

The P, I and D terms need to be "tuned" to suit the dynamics of the process being controlled. Any of the terms described above can cause the process to be unstable, or very slow to control, if not correctly set. These days temperature control using digital PID controllers have automatic auto-tune functions. During the auto-tune period the PID controller controls the power to the process and measures the rate of change, overshoot and response time of the plant. This is often based on the Zeigler-Nichols method of calculating controller term values. Once the auto-tune period is completed the P, I & D values are stored and used by the PID controller.

3 Strategies To Improving Your Golf Game

Why should you work on improving your golf game? For one, the next time that you head out onto the green with your boss you wont feel like a complete fool when he starts talking about his skills. And, youll be able to brag to your buddies about how you came out under par. It can also help you to enjoy the game more so. Maybe you just need a little more practice (time to get away Saturday morning from the wife and kids) or maybe you just need someone to show you a few techniques to help you get the most out of your game. Either way, improving your golf game can happen in just these steps.

* One of the most prolific mistakes that people make in their golf game is their stance. Because of how important the way that you stand is, youll need to make sure that you have it down perfectly. If this sounds hard, it doesnt have to be.

* After improving your stance, you need to take the time to improve your swing and your follow through. When working to improve your golf game, the follow through of your swing will ultimately provide you with an accurate shot.

* Another mistake the individuals make yet need to realize when working to improve their golf game is their use of clubs. Which is the right one to use when you tee off? Which should you use to get out of the sand dune? While you may think you know the answer, you probably dont.

Okay, so these are the things that you should work on to improve your golf game, but how do you actually do it? What should you look for? While you can definitely learn from the web, it often makes more sense to see the difference in what you are doing and what you should be doing, not just reading it. For that, you should consider one of several options.

* First, you can enroll in a few golf courses at your local golf club. This is the best option because it allows hands on, personal training. It is also the most expensive.

* second, you could also take some courses through your local community center. A good choice and it is less expensive.

* You can also work on your golf game by using videos designed to help you each step of the way. The videos can be purchased throughout the web and allow you to actually see the right way to stand and swing your club.

improving your golf game just got a whole lot easier!
