Means of communication

Maturitní otázka c. 23. Means of communication Introduction A few centuries ago people knew only a few kinds of communication. They could speak to each other, they could send their message from one place to another by smoke signals , they used mail. Later on, they also had some newspapers. The first expansion of media was when the radio and television were invented. The second and the biggest boom started in 1960s when the first communication satellite was launched into orbit. There are 4 main media: Newspapers, TV, Radio and the Internet. Today's people take this as an ordinary thing and we don't realise that we nearly can't live without it. Media are very important for us...

Exami kysimused-vastused

STYLE The term "style" is polysemantic (has many meanings): a Latin word "stilus" originally meant a writing instrument used by ancient people. Already in classical Latin the meaning was extended to denote the manner of expressing one's ideas in written or oral form. Jonathan Swift defined style as "proper words in proper places". In present day English the word "style" is used in about a dozen of principle meanings: 1. the characteristic manner in which a writer expresses his/her ideas (e.g. style of Byron) 2. the manner of expressing ideas, characteristic of a literary movement or period 3. the use of language typical of a literary genre (e.g. the style of a comedy, drama, novel). 4. the selective use of language that depends on spheres / areas of human activity (e.g. style of fiction, scientific prose, newspapers, business correspondence, etc.). STYLISTICS Stylistics ­ is the study of s...

Piletid vastustega

This corner can be used for analyzing the circuit topology, but should not be used for actual circuit design. At turn on, the diode can be considered as an ideal switchbecause it turns on rapidly as compared to transients in the circuit. 6) One of its main applications is in rectifiers, circuits that convert the Alternating voltage or alternating current into direct voltage or direct current. It is also applied in detectors, which find the signals in the noisy operation conditions. The third application is in switching circuits because an ideal rectifier acts like a perfect conductor when forward biased and lik a perfect insulator when reverse biased. 7) A power diode is more complicated in structure and operational characteristics than the small signal diode. The forward bias characteristic of the power diode is approximately linear, which means that the voltage drop is proportional to the omic resistance and to the current....

Projekt

The Zoiper' interface Also it is necessary to choose the right audio codec for VoIP transmission which ensure us the right quality of MOS from 3,5 to 4. In this case the best choice for us will be a G.729 codec ­ a speech codec, with the low-latency G.729 audio data-compression algorithm, which partitions speech into 10-ms frames. It uses an algorithm called conjugate-structure ACELP (CS-ACELP). G.729 compresses 16-bit signals sampled at 8 kHz via 10-ms frames into a standard bit rate of 8 kbps, but it also supports 6.4-kbps and 11.8-kbps rates. In addition, it supports voice-activity detection and comfort-noise generation. Video conferences are too important for our customer. For video codec we chose the default H.261. This standard, developed in 1990, was the first widely used video codec. It introduced the idea of segmenting a frame into 16 3 16 "macroblocks" that are tracked between frames to...

Autodes kasutatavad pneuma-ja hüdrosüsteemid

As the vehicle occupant collides with and squeezes the bag, the gas escapes in a controlled manner through small vent holes. The airbag's volume and the size of the vents in the bag are tailored to each vehicle type, to spread out the deceleration of (and thus force experienced by) the occupant over time and over the occupant's body, compared to a seat belt alone. The signals from the various sensors are fed into the Airbag control unit, which determines from them the angle of impact, the severity, or force of the crash, along with other variables. Depending on the result of these calculations, the ACU may also deploy various additional restraint devices, such as seat belt pre-tensioners, and/or airbags (including frontal bags for driver and front passenger, along with seat-mounted side bags, and "curtain" airbags which cover the side glass)....

The Cataclysmic Death of Stars

Lately they've had two big breaks. One is a revelation about potent blasts of high-energy gamma rays that come from distant points in the heavens. For decades astronomers have puzzled over their origins, but space probes recently clinched the answer, which Woosley proposed more than a decade ago: Many gamma-ray bursts are the early warning signals from supernovas, emitted minutes before the explosion. The link offers a glimpse of events leading up to the actual explosion--another mystery. There, too, researchers have made headway. Looking not at the heavens but at computer models of supernovas, some think they have figured out what may trigger the final cataclysm. The missing element may be unimaginably powerful reverberations--the sound of a star singing its own swan song....

"Anna Karenina" kokkuvõte

He is enraged inside and tells Anna he will divorce her and have his sister raise the boy. Shortly after, Anna has an ominous dream, which predicts her forthcoming death. The dream continues to recur throughout the rest of the book. Meanwhile, Levin and Kitty meet once again at a party thrown by Stiva. Levin realizes that Kitty must love him because of the longing look in her eye. He proposes, using covert signals that she, but no one else, understands. "Levin got up and escorted Kitty to the door. In their conversation everything had been said; it had been said that she loved him, and that she would tell her father and mother that he would come tomorrow morning." This is an example of the fact that Levin and Kitty relate to each other on a subconscious, intuitive level. They equal harmony, the kind Levin has always been searching for. The same could hardly be said of Anna and Vronsky. Levin...

Homereading - body language

Observing hidden feelings Increased attention to body language will allow you to observe hidden feelings, prejudices and sexual intentions; all through your eyes and the other senses we use to perceive the world around us. Body language is the movements of arms and legs, body posture, the manner in which you sit, facial expressions, gait, eye movements and regular gestures such as stroking your hair, touching your nose, etc. Tilting your head signals that you are not dangerous. This is claimed to be a consequence of your mother tilting her head when she pitied you as a child. She showed you that she wasn't angry at you but wanted to comfort you. Your mother also patted her hand or your head when she was comforting you. We continue to do this even after we've grown up and don't have our mother there to do so anymore. We pat ourselves on the cheek, on the arm, or rub our hands together....

Uurimustööks vajalik teada

Genes in the nucleus do indeed represent blueprints for proteins, the molecules responsible for physical traits and the mechanics underlying behavior. However, it is now recognized that the regulation of gene expression, that is the switching on and off of genes, is not a property of the genes themselves, but is controlled by environmental signals (Nijhout, 1990). We are also now aware of the fact that organisms under stress are able to actively alter their DNA and create new genes in an effort to accommodate environmental challenges (Thaler, 1994). Rather than being genetically predetermined, organisms develop in balance with their environment and purposively select, or if necessary rewrite, what they perceive to be appropriate gene programs to ensure their survival....

Kvalitatiivne uurimustöö Emotsioonide regulatsioon ja stress

, 2003; Rohleder et al., 2002,). Psychological and other forms of stress influence the sympathetic nervous system, hypothalamus­pituitary­ adrenal (HPA) - axis, and immune system; the interaction between these systems is complex (Raison et al., 2003, Pariante & Miller, 2001; Adler, Felten & Cohen, 2001). Activation of the HPA axis by physical or psychological stress begins with corticotrophin-releasing hormone (CRH) secretion from the Hypothalamus, CRH then signals the Anterior Pituitary gland to secrete Adrenocorticotropic hormone (ACTH), ACTH then acts on the Adrenal gland which then produces glucocorticoids such as corticosterone and cortisol (Figure 3) which have important metabolic and immunological effects (Arzt, 2001; Hoffman-Goetz & Pederson, 1994; Fitzgerald, 1998).

The surgeon, Dr. Victor L. Perez, said it could help people with severely scarred corneas from chemical or combat injuries. Other techniques focus on delaying blindness, including one involving a capsule implanted in the eye to release proteins that slow the decay of light-responding cells. And with BrainPort, a camera worn by a blind person captures images and transmits signals to electrodes slipped onto the tongue, causing tingling sensations that a person can learn to decipher as the location and movement of objects. Ms. Campbell's artificial retina works similarly, except it produces the sensation of sight, not tingling on the tongue. Developed by Dr. Mark S. Humayun, a retinal surgeon at the University of Southern California, it drew on cochlear implants for the deaf and is partly financed by a cochlear implant maker....

Guitar creates a joyful atmosphere and gives great mood. I believe that every human beignmust find their own Eva and adam. The first wild human were surrounded by nature and love and peace. Our planet Earth calls us to see it in own spirits. Earht gives us signals how we must live. It's everywhere.. look the birda- they are so independet and free and so connected with the nature.
