Snells Law, Refraction And Reflection Of Ultrasonic Waves

admin

Like light, when an incident ultrasonic wave encounters an interface to an adjacent material of a different velocity, at an angle other than normal to the surface, then both reflected and refracted waves are produced.

Understanding refraction and how ultrasonic energy is refracted is especially important when using angle probes or the immersion technique. It is also the foundation formula behind the calculations used to determine a materials first and second critical angles.

First Critical Angle

Before the angle of incidence reaches the first critical angle, both longitudinal and shear waves exist in the part being inspected. The first critical angle is said to have been reached when the longitudinal wave no longer exists within the part, that is, when the longitudinal wave is refracted to greater or equal than 90, leaving only a shear wave remaining in the part.

Second Critical Angle

The second critical angle occurs when the angle of incidence is at such an angle that the remaing shear wave within the part is refracted out of the part. At this angle, when the refracted shear wave is at 90 a surface wave is created on the part surface

Formula

The relationship between the angle of the incident and refracted sound waves is descibed by the following formula:

Sin(A1)/V1 = Sin(A2)/V2

Where

A1 = The incident sound wave angle in degrees
V1 = The acoustic velocity of the incident material in metres per second
A2 = The refracted sound wave angle in degrees
V2 = The acoustic velocity of the refracted material in metres per second

By simple arrangment the formula may be changed to find any one of the values, provided that the other three unknown values are supplied.

E.g. To find the refracted angle, given the incident angle and velocity and the refracted material velocity the equation is rearranged as below:

V2 * (Sin(A1)/V1) = Sin(A2)

Getting the inverse of the answer, that is the inverse of Sin(A2) will return the angle in degrees of the refracted angle.

The Difference between Farsi and Persian

admin

Commonly, the term “Persian” has been used in the English language, describing both the country of Iran and the language that the people have been using since the rise of the first Persian Empire. Although the word Farsi is increasingly used to describe the Persian language, it is still linguistically incorrect, especially in addressing the language itself.

This has always been an issue in American and European media; they have always used the word Farsi to refer to the Persian language. However, people around the world, especially Iranian people are not in favour of the linguistic term that Western people normally use in the media.

So, how should these two words be used in English and other Western languages?

It should be clear that using the appropriate term for a language is significant in the history and culture of the Iranian people. Thus, an improper address for the language term of the Iranian nation may create insult and rudeness to the heritage of Iranian culture.

The Persian language or New Persian is an Indo-European language; it is one of the Modern Iranian languages, along with Kurdish, Baluchi, Pashto, and Ossetic. The New Persian language is described as a member of the Western Iranian branch of the Iranian languages, which are a subgroup of the Indo-Aryan family of languages. Hence, Persian is related to European languages, such as the English language.

Over the years, Persian has developed through three distinct stages: Old, Middle, and New. New Persian is directly derived from Middle Persian, and has two phases: classical and modern, and both variants are mutually intelligible.

But what are really the differences between Farsi and Persian?

Farsi is an Arabic form of Parsi, while Persian is the English equivalent term for the word Farsi. This is same status as the German language has. Although the native name of the German language is Deutsch, linguists would never use Deutsch in place of German as a term in the English language.

The New Persian language is one of the most spoken languages in South Asia, and there are also significant numbers of immigrants who speak the Persian language, such as in the U.S, Canada, Australia, and Europe.

The bottom line is that the English name of this language is Persian, and Farsi is its internal or domestic equivalent. However, the term Farsi is used by Iranians to show the distinction of their languages from other forms of Persian; while term Persian encompasses all aspects of the Iranian culture.

Persian is a language that provides ultimate access to the culture and history of the Iranian people. In addition, experts and Persian native speakers agree that writers, translators, media, educators, and researchers should use the word Persian for Iran language system, instead of any usage of the word Farsi.

Millions of people around the globe apply for an American visa, every year, in order to gain entry to this land of coveted opportunities. However, only a few and deserving out of them gain entry to this land. Ask any immigrant what is his biggest fear? The answer would be, -Deportation to their home countries.- The illegal immigration reform added the removal proceedings in an amendment process to Immigration and Nationality Act (INA) to expel aliens and bar them from entering the United States. .

It is a routine procedure for all those being served a deportation to have a hearing in fort of the immigration judge to explain his/her side of the story. However, a foreign national can be deported without any hearing in many cases. An Immigration law firm in New York talks about these types of deportation procedure in the section below.

In both the processes, the individual requires help from an experienced immigration attorney to take a person out of the immigration entangles. Expedited removal process –

This also includes immigrants who have furnished false information at the port or border in order to gain entry. Aliens who have gained entry by providing false and forged documents are also removed by this process. In most cases, aliens are deported without hearing. However, in some cases, it involves those seeking asylum, the alien is interviewed by an asylum officer. An individual is barred from entering the United States for a period of 5 to 20 years if removed by the expedited removal process. This process also applies in cases in which an alien has been convicted of a crime such as those related to drug, rape, murder, sexual abuse of minors and possession of fire arms. However, these aliens are deported only on the completion of their prison term

In the part-II of the article, we will look at the various aspects of removal due to an administrative process.

Understanding The Law Of Attraction through Personal Development

admin

The law of attraction has been around for years but maybe you’ve just become aware of its popularity and could be wondering how to incorporate it’s principles into your life.

In order to correctly apply this law one must first understand what the Law of Attraction means and what it’s direct principles are. Lucky for you they’re pretty simple and easy to understand. The first thing that you learn from the Law of Attraction is that -Negative attracts negative and positive attracts positive-. It also states that the Universe (God, Most High, etc.) can understand our subconscious mind and presents things according to the way that we think. Here are some real simple strategies from the Law of Attraction that will turn in joy, happiness and positive rewards: 1.Always show gratitude – For you to apply the Law of Attraction on a continuous basis, you have to always give thanks. No matter what we must profess thanks for everything that we have up to this point in life. In order to be rewarded with positive things you have to sincerely practice gratitude on a continuous basis. A great way to practice gratitude on a daily basis is to give thanks every morning when we rise and at night before going to bed each day. Our subconscious mind is most receptive during these times of the day providing better results of the Law of Attraction. Predicating gratitude reminds us of all of the good things that we have in life and keeps us humble. 2.Dodge Negative Feelings and Thoughts – Like most people your life is stress filled and extremely hectic at times so it’s easy for you to become negative and frustrated about the situation and issues you’re in. The principles of the Law of Attraction teach us to redirect those feelings immediately by simply thinking about something that makes us feel good like a song or person. Don’t forget that negative attracts negative and positive attracts positive. Because of this we must practice focusing on positive things and not the negative. Focusing on the negative will only attract more negative into your existence. For example, if you feel over weight, instead of thinking about how much you hate the way you look, think about how you would look at your perfect weight. There are people all around the world who live a positive existence; those are the kind of people that you must imitate. 3.Speak What You Want – According to the Law of Attraction, you can speak things into existence. Meaning that if you request it, it will be given to you. Do you want a successful business, love, children, financial freedom? You can have any of these things, you just have to request it through your subconscious. For instance, if you’d like wealth brought into your existence, you must truly picture yourself with wealth in your life. Imagine how happy you would be, the smile on your face while living the good life of wealth. Remember to be sincere and really see what it is that you want to exist in your life. Only real positive energy will attract more positive things. Our subconscious is a powerful tool and the Law of Attraction proves that to us. If used correctly it can provide us with all of our heart’s desires. Apply the principles of the Law of Attraction with an open heart and your life will be rewarded with many positive things.

The Importance Of Proper Criminal Law Representation

admin

Whether you have been arrested for a felony or only charged with a minor offense, your first step towards freedom is to secure an experienced defense attorney to advise you in your trying time.

Consulting an experienced lawyer immediately after your arrest can make an enormous difference in the outcome of your case. The criminal justice system is too complex to be successfully navigated by someone without legal training. A good criminal lawyer with years of experience defending cases like yours can make these complexities work in your favor.

A good lawyer can help you decide whether to plead guilty or take your case to trial. Initially, you may see pleading guilty as the quickest way to get out of the legal system. This option may appear very attractive when you are confronted by a prosecutor describing the harsh punishments that you could receive if found guilty at trial for a crime that you may believe you have committed. The advice of an experienced attorney is indispensable at this point, because the repercussions of a guilty plea can reach far into the future, saddling you with a permanent criminal record that will make many employers reticent to hire you.

If you decide to plead guilty, a good defense attorney with a professional relationship with the prosecutor handling your case can make the difference between a favorable sentence and a long time behind bars. Your lawyer may even be able to secure a sentence that will eventually be removed from your record, an impossible feat without proper legal representation.

For most defendants, the courtroom is a nerve-wracking place. Not so for the defense attorney, who spends much of his time before a judge and jury. Your lawyer can use his experience in this area to prepare you both for the questions you will be asked and for the emotions that may overwhelm you at trial. Knowing that you have a professional advocate on your side can relieve much of the anxiety and uncertainty that comes from a trial.

At trial, the burden of proving your guilt falls on the prosecution. Even if you know that you have committed a crime, an experienced lawyer can often prevent the prosecution from convincing the jury of your guilt, especially if you have only been charged with a minor crime.

If you are convicted at trial, a defense attorney who is familiar with local sentencing procedures can convince the judge to reduce your sentence or to convert jail time to community service or probation.

The stress of arrest, the complexity of the legal system, and the severe consequences of a criminal record make securing proper legal representation in your criminal case a necessity.

I Love You. . .Different Men,Different Meanings

admin

I can sleep with her, marry her, take care of her, but love thats something else,” said Tony, a married man in his late forties. “Guys dont like to talk about love. They dont know what to say. Of course guys do love. But they express it differently.” Despite this fact, most women do not feel happy unless they hear those golden words, I love you. Men need to hear them as well. And yet, as much as men want love, many fight it to the last minute. Love can make men feel vulnerable, childlike, and unable to do whats expected of us, especially those who believe theyre functioning in a dog eat dog world.

Different types of men express their love differently. In fact, love means different things to a man, at different times in his life. A woman needs to be alert to who the man she is with is, and what love means to him. Although most women wait to hear the golden words, “I Love You,” there are many different ways that men use to express what they are feeling.

The first way is simply by saying “I Love You.”

Actually, saying these words is a huge step for some men. It means a lot more than simply expressing a feeling. For some it feels like a life commitment, for others it is fraught with danger.

“When I say I love you,” said Steve, “I feel like Im taking my life in my hands and giving it to her. Its scary. Ive got to really trust her and know she wont throw my love away in order to actually say the words to her.” In this case the fear of rejection comes up strongly. Rejection is enormously painful for most men, and saying “I Love You”, can be an invitation to be hurt. Most men must feel very secure in the relationship and in the womans feelings for him, before hell dare say those words. For others, saying “I love you,” means, Im offering a commitment. Im going to be here to do things for you.

For many men, love is expressed through action, so these words are a promise of what is to follow. Simply by saying these words they feel they are agreeing to be there to give to support her. If they dont do it, theyll feel like a heel.

For others, the words means, Im not leaving, or Ill always be faithful. This can be very scary for some men. They feel the words themselves are a promise, and if the promise is broken, they will suffer as well.

However, there is another type of man, The Lovers, Dreamers and Peter Pans, who enjoy falling in love and letting the world know it. These men will say “I Love You” easily.

There are many different motives behind their words though.

Some say it to get a woman to make love with him, others to enter into a romantic fantasy, some to feel as though they are the great lover of all time. By saying these words, others seem to be offering the woman the world ( that they have no intention of giving.)

Others say it just for the sheer pleasure of seeing how good it makes the woman feel, and how powerful this makes him feel.
