Независимый причастный оборот. Независимый причастный оборот – это сочетание существительного в общем падеже (или местоимения в именительном падеже) с Participle I или Participle II

 

Независимый причастный оборот – это сочетание существительного в общем падеже (или местоимения в именительном падеже) с Participle I или Participle II, в котором существительное (или местоимение) выполняет роль подлежащего по отношению к причастию и не является подлежащим всего предложения. Такой оборот логически связан с предложением и по существу является его обстоятельством. Подобно обстоятельству, независимый причастный оборот может предшествовать подлежащему, т.е. стоять в начале предложения или следовать за группой сказуемого в конце предложения. Этот оборот всегда отделяется запятой от остальной части предложения.

В начале предложения в функции обстоятельства на русский язык этот оборот переводится, как правило, придаточным предложением причины, времени, условия с союзами так как, когда, если и др.;

 

The weather being fine, we went for a walk. Так как погода была хорошая, мы пошли гулять.
Weather permitting, the airplane starts. Когда погода позволит, самолет взлетит.

 

В конце предложения независимый причастный оборот переводится на русский язык чаще всего самостоятельным предложением или присоединяется союзами а, и, причем:

The cars at that time were very small, the engine being placed under seat. Автомобили в то время были очень маленькими, и двигатель размещался под сиденьем.

 

Некоторые независимые причастные обороты, начинающиеся предлогом with, переводятся так же, как и обороты без with.

With supersonic planes at a speed five to six times above the speed of sound, it will be possible to cover the distance between Tokyo and Moscow in less than 2 hours. Когда ультразвуковые самолеты будут летать со скоростью, в 5-6 раз превышающей скорость звука, можно будет пролетать расстояние между Токио и Москвой меньше, чем за 2 часа.

Text A

WHAT IS SOUND?

 

Sound is energy and, like other forms of energy, can be useful to man. The vast range of possible frequencies and timbres that characterizes both speech and music makes sound an effective medium of communication. Even ultrasound – sound above the hearing range of man – has many practical uses. Most sounds don’t carry great deal of energy. The noise of a symphony orchestra playing as loudly as possible involves for example, sound energy equivalent to the light and heat energy from only a low-powered electric lamp. Our hearing sense is more easily saturated (in energy terms) than our visual sense.

Sound is a particular form of kinetic energy (energy of motion) produced when an object vibrates and a medium, such as air, vibrates in response. The sound of a car crash booms out as the surfaces of the two colliding vehicles vibrate with the force of the collision; music comes from a radio as a loudspeaker vibrates; and talking and singing result from vibration of the vocal cords.

As an object vibrates it sets the air molecules around it vibrating. Where the air molecules gather together a region of higher pressure (compression) occurs. Where they move apart a region of lower pressure (rarefaction) occurs. As compressions and rarefactions move through the air they form a sound wave. At the ear they set the eardrum vibrating and we hear sound.

If a surface vibrates more strongly, the pressure difference between the compressions and rarefactions is greater and the sound is loud. The frequency of vibrations affects the pitch, or note, of the sound. Fast vibrations produce compressions and rarefactions that are close together and the pitch is high. A slower speed of vibration causes the compressions and rarefactions to be farther apart and the sound is lower in pitch.

A sound wave moves out from its source in all directions, traveling at a speed of 1,087 ft (331 m) per second or 741 mph (1,194 kph) in air at 0ºC at sea level. The speed is slower at high altitudes as air less dense there, and faster in water and metal because these substances are more elastic than air and transmit vibrations more rapidly. The speed also correlates with temperature of the medium. Sound cannot move through a vacuum because there are no gas molecules to vibrate and transmit the sound.

Like other waves of energy, sound normally travels in straight lines, but sound can turn corners. It is reflected whenever it strikes a surface such as a wall or floor and is diffracted or spreads out as it passes through an opening such as a window.

The loudness of a sound can be measured with a decibel meter and the result given as a number of decibels (dB). The scale is logarithmic – a sound that is twice as loud as one at the threshold of hearing is 10 dB greater, not twice as great. Strictly, the meter measures the intensity of the sound, which is related to the pressure differences in the sound wave. (Loudness is the strength of the sensation received in the eardrum and transmitted to the brain). The human ear does not hear all frequencies of sound in the same way, and a low sound is perceived as being less loud than a high sound of the same intensity.

The number of the compressions occurring every second is called the frequency of the sound and is measuring in hertz (Hz), equal to cycles per second. The higher the frequency, the higher the pitch.

Noise does not have any particular pitch and covers a wide frequency range. Very loud noise is dangerous as well as a nuisance, because continuous exposure to sound of more than 100 dB – the levels produced by jet aircraft and machines in many factories – soon results in a permanent reduction in hearing ability. Low frequency noises are particularly hazardous because they do not seem to be as loud as higher pitches, and tests have shown that very high levels of low frequency sound and infrasound (sound below the hearing range of the ear) quickly result in vertigo, nausea, and other physical effects; military scientists have even experimented with using infrasound as a potential weapon.

Acoustic engineers work to reduce noise and improve sound in many ways. A consideration of acoustics in the design of a machine such as a jet engine can reduce the amount of noise it makes. Buildings can also be designed to prevent the transmission of sound through them. A steel framework tends to distribute sound throughout a building, but the use of sound-absorbing materials in and on floors, walls, and ceilings prevents sound from getting into and out of rooms. In concert halls the reflection of soft sound inside the hall is rigorously to provide an exact amount of echo and give the best quality sound. This may be assisted by electronic amplification, although very loud music loses clarity in a concert hall. Some recording studios have completely absorbent walls to remove all echo and ensure total clarity whatever the type of music being performed.

GSM

During the early 1980s, analog cellular telephone systems were experiencing rapid growth in Europe, particularly in Scandinavia and the United Kingdom, but also in France and Germany. Each country developed its own system, which was incompatible with everyone else’s in equipment and operation. This was an undesirable situation, because not only was the mobile equipment limited to operation within national boundaries, which in a unified Europe were increasingly unimportant, but there was a very limited market for each type of equipment, so economies of scale, and the subsequent savings, could not be realized.

The Europeans realized this early on, and in 1982 the Conference of European Posts and Telegraphs (CEPT) formed a study group called the Groupe Special Mobile (GSM) to study and develop a pan-European public land mobile system. The proposed system had to meet certain criteria:

· good subjective speech quality

· low terminal and service cost

· support for international roaming

· ability to support handheld terminals

· support for range of new services and facilities

· spectral efficiency, and

· ISDN compatibility.

In 1989, GSM responsibility was transferred to the European Telecommunication Standards Institute (ETSI), and phase I of the GSM specifications were published in 1990. Commercial service was started in mid-1991, and by 1993 there were 36 GSM networks in 22 countries, with 25 additional countries having already selected or considering GSM. This is not only a European standard – South Africa, Australia, and many Middle and Far East countries have chosen GSM. By the beginning of 1994, there were 1.3 million subscribers worldwide. The acronym GSM now (aptly) stands for Global System for Mobile telecommunications.

The developers of GSM chose an unproven (at the time) digital system, as opposed to the then-standard analog cellular systems like AMPS in the United States and TACS in the United Kingdom. They had faith that advancements in compression algorithms and digital signal processors would allow the fulfillment of the original criteria and the continual improvement of the system in terms of quality and cost. The 8000 pages of the GSM recommendations try to allow flexibility and competitive innovation among suppliers, but provide enough guidelines to guarantee the proper interlocking between the components of the system. This is done in part by providing descriptions of the interfaces and functions of each of the functional entities defined in the system.

WHAT IS GPS?

GPS, short for Global Positioning System, is a space-based positioning system that uses satellites and computers to measure positions anywhere on the land, air, or sea at any time. This system is distinguished from other positioning systems by its 24-hour, seven-day per week availability and its pinpoint accuracy.

The system was born from communication problems U.S. troops experienced in the Vietnam conflict. During that time a localized system, LORAN, was used that was prone to problems inherent in radio communication such as poor reception during ominous weather or during the night. The U.S. Department of Defense responded to this problem by investing into a system known as the Navy Navigational Satellite System, TRANSIT, which most recently evolved into GPS.

GPS is a second generation, satellite-based, positioning system that is available anywhere and anytime and is capable of measuring land, air and sea positions with millimeter accuracy. GPS is referred to as a system because it is an assemblage of three distinct components or segments: Space, Control, and User.

The Space Segment refers to the constellation of satellites and the navigational data they provide. The Control Segment refers to monitoring and updating of the satellites’ clocks and navigational messages by a master control station that uses five regional monitoring stations distributed around the world. Lastly, the User Segment refers to the GPS receivers that calculate the time required for a radio signal to travel from the visible satellites to the receiver in order to measure its position using a technique called triangulation.

GPS has a civilian and military user community. Although GPS is funded by the U.S. DoD, civilians worldwide can use GPS’ Standard Positioning Service (SPS) provided a proper receiver is used. SPS provides positional accuracy of 100 meters in 2-Dspace with 95% confidence. The U.S. Military and its allies use a more highly accurate service called Precise Positioning Service (PPS) that is capable of accuracy within ten meters in 3-D space 95% confidence.
