Kingda Ka is named for a 500-pound mythical tiger. A tiger in the safari was named after the roller coaster. It is surrounded by bamboo to make it look more real. It also plays music.
The ride has 4 trains with 5 cars. They are 9 rows in each car that can hold 18 people and there are 2 people in each row. Each seat has shoulder harnesses and buckles that keep the shoulder harness down to make sure passengers are safe. At the top, passengers are weightless for a second, and after riders enjoy a beautiful view, it is followed by a drop.
Passengers must be 4´7 to ride Kingda Ka.
The train may sometimes experience a rollback after it is launched. A rollback happens when the train doesn't make it to the top of the hill and rolls back down the track. The launch track has magnetic brakes so that the train doesn't go back to the station.
Vulnerability
Vulnerability means the extent to which changes can hurt or harm a person or a system.
In context with natural hazards and natural disasters, "vulnerability" is a concept that looks at the relationship that people have with their environment and at social aspects.
So it links environment to social forces and institutions and the cultural values that sustain and contest them. “The concept of vulnerability expresses the multidimensionality of disasters by focusing attention on the totality of relationships in a given social situation which constitute a condition that, in combination with environmental forces, produces a disaster” (Bankoff et al. 2004: 11).
Complex definition: Vulnerability is the susceptibility to physical or emotional injury or attack. It also means to have one's guard down, open to censure or criticism; assailable. Vulnerability refers to a person's state of being liable to succumb, as to persuasion or temptation (see Thywissen 2006 for a comparison of vulnerability definitions).
Harm
Harm is physical or psychological or emotional damage or injury to a person, animal or other legal entity.
It is generally believed that humans, in addition to other sentient animal species, possess an aversion to causing harm to others.
Many religions consider any harm to another person a sin.
Liquid crystal display
A liquid crystal display is a special thin flat panel that can let light go through it, or can block the light. (Unlike an LED it does not produce its own light). The panel is made up of several blocks, and each block can be in any shape. Each block is filled with liquid crystals that can be made clear or solid, by changing the electric current to that block. Liquid crystal displays are often abbreviated LCDs.
Liquid crystal displays are often used in battery-powered devices, such as digital watches, because they use very little electricity. They are also used for flat screen TV's. Many LCDs work well by themselves when there is other light around (like in a lit room, or outside in daylight). For smartphones, computer monitor, TV's and some other purposes, a back-light is built into the product. This is an LED or Cold Cathode Fluorescent Light (CCFL).
The LCD uses technology called electro-optical modulation. This means it uses electricity to change how much light passes through it.
Each pixel (block) of an LCD is made of a thin layer of molecules between two electrodes and two polarizing filters. The electrodes provide electric power to the liquid crystal layer, and don't block the light. Light travels with 'polarity' or direction, and a polarizing filter only lets light with one kind of polarity to go through it, like trying to slide a ruler through a narrow opening. Only when the ruler is lined up right, will it fit. These two filters are perpendicular to one another, so the narrow openings are in different directions. This means that without the liquid crystals between them, they would block all light from passing through – whatever light gets through the first filter will not fit through the second filter.
The layer of liquid crystals between the two filters can 'twist' the light so that the polarity changes. This means the light can then pass through both filters, and the pixel appears clear. When giving an electric current to the liquid crystals, the molecules will untwist and will not change the light. The filters then block the light and the pixel appears dark.
When a large number of pixels are needed in a display, it becomes difficult to have enough wires and electrodes to control each pixel and still have a clean display. Instead, the display is "multiplexed". In a multiplexed display, electrodes on one side of the display are grouped and wired together (usually in columns). On the other side, the electrodes are also grouped (typically in rows), with each group getting a voltage sink. By turning on one row and one column, each pixel can be controlled one at a time.
Body language
Body language is a form of non-verbal communication. Body language is about using behaviour to communicate. Both people and animals use this form of communication. Part of this behaviour is done subconsciously. It is therefore different from communicating using sign language, for example. Communication using sign language is intentional, body language is not.
The forms of behaviour used in body language include body posture, gestures, facial expressions, and eye movements.
Body language may provide clues as to the attitude or state of mind of a person. For example, it may indicate aggression, attentiveness, boredom, a relaxed state, pleasure, amusement, and intoxication.
Body language is significant to communication and relationships. It is relevant to management and leadership in business and also in places where it can be observed by many people. It can also be relevant to some outside of the workplace. It is commonly helpful in dating, mating, in family settings, and parenting. Although body language is non-verbal or non-spoken, it can reveal much about your feelings and meaning to others and how others reveal their feelings toward you. Body language signals happen on both a conscious and unconscious level.
Body language is less exact than spoken language, so you have to be careful about how you interpret it. A certain movement or facial expression may be quite meaningful, or it may mean nothing at all. As a starting point, the following sections provide you with some common body language terms and their generally-accepted meanings.
Positive body language is generally quite reliable as an indicator of a person's feelings. It signals interest in the other person and in the conversation.
Relaxed posture - Comfortably seated, relaxed breathing, no visible stiffness or abrupt movements. These indicate no major barriers to communication.
Arms relaxed - Uncrossed arms and hands open (palms up or otherwise visible to the other person) are signs of openness.
Good eye contact - Looking in the other person's eyes, particularly when they are speaking, indicates interest in that person. Proper eye contact involves looking away occasionally to avoid staring.
Nodding agreement - When nods are used to punctuate key things the other person has said, they signal agreement, interest and understanding. However, continual unconscious bobbing of the head usually indicates that the listener is tuning out.
Taking notes - Shows interest and involvement, particularly if notes are on what the other person is saying.
Smiling/adding humour - This is a very positive sign. It signals a warm personal relationship.
Leaning closer - Reducing the distance between two people, particularly when the other person is speaking. Indicates interest is up and barriers are down.
Gesturing warmly - Talking with hands, particularly with palms open, indicates involvement in the conversation and openness to the other person.
For all of these positive gestures, moderation is the rule. When they are exaggerated, they can become more negative than positive.
