How Does A Music Synthesizer Work?

Posted by , No Comments

Submitted by: Bobby Carnes

A music synthesizer makes sounds by using an electrical circuit as an oscillator to create and vary the frequency of sounds in order to produce different pitches. As long as the pitch is within the range of frequency that can be heard by a human ear, it s known as a musical pitch (so a dog whistle wouldn t count) as a musical pitch. You can use a keyboard to vary these pitches at discrete intervals that correspond to the notes on the musical scale. If you put several oscillators together, you can combine several pitches to create a chord .

OK, we ve got pitch down (at least in a very simple sense). How do you vary the tone of a particular pitch? That is done by playing a given pitch with waveforms of different shapes (common waveforms include sine, square, sawtooth, and triangle waveforms). Since the harmonic structure of these waveforms differ, our ears interpret them as different tones. The sound you will hear can also be modified by voltage-controlled amplifiers (VCA) and voltage-controlled filters (VCF).

Synthesizers are able to only mimic the sounds of non-synthetic instruments, but also to create sounds that absolutely cannot be played by anything but a music synthesizer. That is because a music synthesizer is well-suited to delicate manipulations of its oscillators. Nevertheless, it s a lot easier for a synthesizer to create entirely new sounds than to mimic the sounds of acoustic instruments because the waveforms of acoustic instruments are so complex. Interestingly, once complex sound that synthesizers so far have been very bad at reproducing is the human voice (although improvements are being made in this technology).

The entire electronic music scene would be virtually impossible without the use of synthesizers (no doubt some wish it were). Nevertheless, the number of sounds that a musician has to work with has been exponentially increasing in recent decades, and we have only scratched the surface of the creative possibilities. Imagine the consequences if a machine was invented that could generate 100,000 hitherto unknown colors?

Monday, March 12, 2007

A gas line at Lake Weatherford, Texas exploded Monday afternoon. No one was injured in the explosion, though several vehicles were completely destroyed in the explosion. Flames are reported to be at least a hundred feet into the air.

Workers were laying pipes near pipes that were already installed and running, when the explosion occurred. As many as 20 workers were working on the site of the explosion when flames broke out. The local fire department has not ascertained exactly how many people were at the scene.

At least 10 cars can be seen on fire near the site of the explosion and homes and businesses in North Parker County have no power due to the fire.

US stock markets reach 12-year lows
Posted by , No Comments

Thursday, March 5, 2009

US stock markets dropped to twelve-year lows on Thursday, amidst falling confidence in the financial sector and worries over whether the US automobile manufacturer General Motors will be able to keep operating.

The Dow Jones Industrial Average dropped by 4.08%, or 280.52 points, at the closing bell, reaching a level of 6595.32, a new 12-year low. The Nasdaq Composite lost 54.15 points, or 4%, to 1299.59, while the Standard & Poor’s 500 plunged by 30.27 points, or 4.25%, closing at 682.60.

Every stock in the Dow Jones, other than Wal-Mart, either lost ground or remained even, and all stocks in the S&P 500 index lost ground.

General Motors’ shares lost 15.5% after the auto firm announced that its auditors had “substantial doubt” over whether it would be able to keep operating.

Shares of financial companies were lower by nine percent, with Bank of America losing 11.7% and Citigroup falling by 9.7%.

“What’s most worrisome is that we haven’t hit the crescendo yet,” said Bill Groeneveld, the head trader for vFinance Investments. “Asset-management divisions are getting calls to just liquidate everything, and we haven’t seen the big players come back in at all.”

“This is one of the worst bear markets in the last 100 years; it started out with the credit crisis and the subprime [loans], but it is like a forest fire that has raced across the clearing and ignited other parts: Autos, auto parts, the insurance companies have been hit very hard. The credit crisis is causing an unraveling of industry after industry because the banks don’t lend,” said David Dreman, the chief investment officer of Dreman Value Management.

European markets were also lower today, with the London’s FTSE index losing 3.2% and the DAX index of Germany falling by five percent.

Educating Yourself About No Stitch Cataract Surgery

Posted by , No Comments

byadmin

According to the American Academy of Ophthalmology about 22 million people in the United States over the age of 40 have cataracts. About half of all people over the age of 80 have this condition that clouds the lens of the eye and progressively leads to a decrease in vision. With the only cure found in cataract surgery, learning more about cataracts and their treatment can help you to answer questions for family members.

First, it is important to realize that despite the claims of some supplement manufacturers, there is no scientific evidence that any supplements can reduce the risk of developing cataracts. There is also no treatment except for cataract surgery at this time, but the type of surgery has changed dramatically providing patients with options for very fast healing with reduced risk of complications.

No-Stitch Surgery

Now, most cataract surgery is classified as “no-stitch surgery” because the entire process is done using an extremely fine tube that is inserted into the eye. This tube contains an ultrasound instrument that creates a safe vibration in the eye that breaks up the cataract into small pieces.

The pieces of the cataract are gently suctioned out of the eye and an artificial lens put in place. When the tube is removed the eye tissue simply seals over, without the need for any type of stitches. This entire process is actually known as phacoemulsification and has an extremely high success rate with very few complications.

Local Anesthesia Only

The entire process of no-stitch cataract surgery is done under local anesthesia on an outpatient basis. This anesthesia of the eye is usually done with drops, meaning no injections for those that are a bit nervous about the idea of a needle.

Patients typically do not require patching of the eye and there is minimal healing time required. Some patients, but not all, may experience mild discomfort in the eye for a day or two after the procedure. Most people do not need to drastically change their typical lifestyle during the healing process which can last up to eight weeks.

The benefits of no-stitch cataract surgery make this a good option for a wide range of different patients. You and your doctor can discuss the options, any possible risks, and any concerns that you may have before you decide if this is the right choice for your eye health.

Calls for corporate tax reform in Australia goes unheeded

Calls for corporate tax reform in Australia goes unheeded
Posted by , No Comments

Friday, May 12, 2006

Peter Costello’s budget announcement has led to rejoicing for small businesses, but the lack of joy for those pushing for radical corporate taxation reform has led to many businesses asking “what about us?”

Personal taxation and small business have been the big winners after this year’s federal budget. Although dampened by the twin economic threats of rising interest rates and petrol prices, there should be a reasonable amount of real income savings for both low and high income earners, with those receiving Medicare, or a superannuation benefit, privy to an even lower level of taxation (0% for those on super benefits).

Small business also has benefited from the Howard government’s 11th annual budget, with them receiving a higher level of reducing depreciation, leading to a higher level of deductions in the years following the uptake of new technology or other capital. They are also privy to a AU$435 million dollar tax cut to compensate for their changing accounting requirements under the government’s new AIFRS reporting standards, as well as increasing the uptake of both the small business tax relief scheme and CGT (Capital Gains tax) Concessions.

The budget was not a complete loss for big business however, as superannuation laws have been tweaked to streamline contribution and payment rules previously impeding those with multitudes of staff.

But this is not enough, says Big 4 accounting firm Ernst & Young. In their newly published paper “Taxation of Investment in Australia: the need for ongoing reform”. In it they lead the charge for a greater streamlining and organization of the corporate tax system in Australia, submitting that it will lead to reductions in “disincentives to work save and invest in Australia [as well as improving] the international competitiveness of Australian businesses.” This follows from a recent report brought out by Mr. Costello himself about the need for tax reform in Australia.

A budget night Mr. Costello was notably coy about any future reform of corporate tax in Australia. He alluded to the report by his ministers but kept from outlining the government’s plan precisely.

A Brief Introduction To Technical Trading

Posted by , No Comments

Submitted by: Sean Goudeloc

Many people aspire to get some cash out from the stock market. Even though it is difficult, many have found Forex to be an excellent gateway to become rich and to achieve their long-term goals. And to make sure that they will get something from it, most of them have studied the concepts of technical trading.

This trading is dependent on technical analysis. As you might not know, technical analysis is an effective trading system or tool that helps traders interpret market information for possibilities and opportunities in the trading market. Using this tool, traders can make decisions on whether they will move or not during their trades.

On the other hand, even though it is called technical analysis, its primary goal is to unravel patterns brought on by investor behavior and human psychology. This system uses volume data, price, stock quotes, and stock charts. The results of an analysis of these factors will show traders trends in the financial market.

Technical analysis gives its users an idea if the current trend is bullish or bearish. Bullish, in Forex language, means that investments are having value appreciation, while bearish means that prices are going to have a long-term decline.

Once traders foresee that an investment will have a bullish advance, they would certainly buy stocks from it. However, a trader must be attentive on the support and resistance levels of the stock trends before he buys some stocks.

Technical analysis is not all about identifying positive trends alone. It can also provide insightful information if a sudden reversal occurs. In case you do not know what a reversal means, technically, it is an event wherein bullish trends will suddenly shift to bearish trends. And if you have already read about charting patterns, one perfect example of a pattern that predicts a reversal is the head and shoulders chart pattern.

Since the Forex market is very difficult to predict even with the use of technical analysis, modern traders mix program trading with technical trading. Program trading is a technique wherein large financial institutions make use of computers in trading blocks in stocks.

Traders will let those institutions handle their stocks automatically. And to make sure that they will prevent any massive loss due to the automation, they can set limits on how much the system can buy, and how much the system can lose before it stops trading.

As a word of advice, make sure that you exhaust all the data you can use during your trades. If you limit your analysis by using volume data and share price alone, the results of your analysis might not be as accurate. Do not forget to use or obtain the annual reports and financial statements of corporate investors, for you to get a more accurate evaluation about the merits of a certain stock investment.

The things mentioned here are only snippets of what you need to know about technical trading. Remember that you must never stop learning, reading, and being updated about the stock market and the Forex scene. Put in mind that the greatest weapon you can use in the trading scene to win is data.

One million baby cribs recalled due to potentially fatal design flaw

One million baby cribs recalled due to potentially fatal design flaw
Posted by , No Comments

Saturday, September 22, 2007

The U.S. Consumer Product Safety Commission (CPSC) announced yesterday that Simplicity Inc. is recalling nearly one million baby cribs after two infant deaths have been linked to a design failure.

Simplicity Inc. supplies cribs to large American big-box retailers such as Wal-Mart Inc., and several other giant retailers including Target Corp. and Big Lots Inc.

A dangerous gap can be created if the drop-side of the crib has been installed upside-down, and thus becomes detached. That space can cause infants to be suffocated.

Parents are being urged by the company to check their Simplicity cribs to make sure the drop-side was installed correctly and is not a safety hazard. The cribs being recalled have these model numbers: 4600, 4605, 4705, 5000, 8000, 8324, 8800, 8740, 8910, 8994, 8050, 8750, 8760 and 8996.

The affected cribs cost between US$100 and $300, and were sold between January of 1998 through May of 2007.

Two separate deaths have been reported because the drop-side was installed upside down. Fifty-five non-fatal entrapment cases have been reported. And, the CPSC is now investigating a third infant death involving a newer-style crib.

Simplicity Inc. says the faulty cribs were made in China. However, according to CPSC, the recall is about the design flaws that the U.S. manufacturers designed into the product, not a made-in-China problem.

Michael Jackson’s Neverland Ranch to be auctioned off

Michael Jackson’s Neverland Ranch to be auctioned off
Posted by , No Comments

Tuesday, February 26, 2008

Neverland Valley Ranch, owned by Michael Jackson, is to be sold at auction on March 19, 2008, unless Jackson pays over US$24 million.

Financial Title Company, the trustee of his Santa Barbara County, California, home and amusement park, has foreclosed on the property. They notified Jackson of the foreclosure and sale on Monday. Jackson had only just recently paid an overdue property tax bill of $600,000.

The court filing, addressed to Jackson, says, “You are in default of a deed of trust … Unless you take action to protect your property it may be sold at a public sale.” Fox News published the filing.

The foreclosure includes the ranch and all possessions on the property, inside or out.

The foreclosure auction will take place in front of the Santa Barbara County Courthouse in Santa Barbara. Jackson has until then to pay $24,525,906.61 he owes the title company.

In 2006, Jackson refinanced previous loans that had been bought up by Fortress Investment Group. The $300-million loan was secured with the aid of Sony Music Entertainment. However, the Neverland property was not part of that deal.

Jackson has not lived at Neverland since June 30, 2005, when he moved to Bahrain after a rape charge and subsequent acquittal.

Horse Tack Accessories: Ensuring The Safety Of Riders And Horse

Posted by , No Comments

Horse needs pampering as humans. Good horse- riding accessories can not only add up to the comfort, security and luxury of a rider but act as protective gears for horse too. The two most important accessories- Horse bits and boots are discussed here in detail to enlighten the significance of good horse riding aids. Bits are mouthpiece for the horse used to control the horse. While looking for horse accessories, there are few critical points which should be addressed such as fitting, fabric/material, weight and height. An accessory should be durable and comfortable both for the horse and rider. Such an accessory is horse boots which are again, a protective gear for horse. These boots are made up of aluminum and steel. The grooves in the boots make them light weight and provide a better hold. Balance, shape, extension and support of the boot is very critical to understand. For a safe and joyous ride, the quality and fitting of horse tack accessories should be at par. You should also see to it that horse is comfortable with them. Too tight or too loose mouthpiece is of no use but can put riders life at stake.These above mentioned key points can be understood after the shoeing is done for one week or two. Though, it is very difficult to evaluate the factors with a pen and on a ground, yet critical. You can remove horse boots in winters or whenever you are not riding it. Though, most of the riding experts recommended putting the boots on in winter to prevent any adverse effect on hooves. For an added comfort, you can put in some pads underneath. They also prevent bruises on the sole of horses. However, before you decided to purchase horse tack equipments, consult a professional farrier. Similarly, the mouthpiece should be fitted really well in horses mouth. No bar should remain outside the mouth. Also, see if the mouthpiece has not restricted the saliva secretion of horse and it should not make it dry or painful. Horse bits are equally important for riders safety. If it is not fitted well, rider wont be able to control it properly.
