Describe how the Lempel Ziv text compression algorithm works

/in /by

Describe how the Lempel Ziv text compression algorithm works, illustrating your answer by deriving the sequence of numbers and corresponding bit patterns it would generate when applied to a string starting with the following 24 characters: ABCDABCDABCDABCDABCDABCD … You may assume that the initial table is of size 256 (containing bytes 0 to 255) and that the codes for “A”, “B”, “C” and “D” are 65, 66, 67 and 68, respectively. [12 marks] (b) Estimate how many bits the algorithm would use to encode a string consisting of 1000 repetitions of the character “A”. [8 marks] 4 Comparative

Which is more important in the first year of life, accurate hearing or seeing?

Which is more important in the first year of life, accurate hearing or seeing?

At birth, the sense of hearing is much more dominant than the sense of sight. Normal visual development is the change from just responding to simple brightness or high contrast, toward the organization of details into patterns and the ability to apply meaning to an object or picture.

Is hearing the first sense a baby develops?
Touch is the first sense your baby develops before the senses of smell, taste, eyesight and hearing. Parts of the somatosensory system start to form only a few weeks after conception

Trichromatic Theory of Color Vision

/in /by

Annabelle is a creative arts teacher at her local high school. She is attempting to teach her students about colors and add depth to the paintings, short films, or other types of media they create as part of her class.

Part A In a lesson on color, Annabelle describes how mixing colors of light is different than mixing colors of paint. Unfortunately, not all her students are able to distinguish between colors and are having difficulty in their first project, making a color wheel.

Explain how the following theories may impact these lessons in her classroom.

CASE STUDY 7.2 A Single Crisis Session

-old woman who was transported to the hospital during the early morning hours by her sister,  Mary.  Lenora presented as visibly upset,  very angry,  shaking, disheveled, and crying uncontrollably.

Mary told the attending nurse that Lenora had been out drinking earlier that night and met a man. Mary explained that he  was  buying  Lenora  drinks  and  at  one  point  must  have  slipped  her  a  “roofie.”

Lenora did not recall what took place, but when the drug wore off she found herself alone in a  hotel room several blocks from the bar and unclothed.

Lenora reported that she was sexually assaulted and raped several times.  Mary also shared that  Lenora “has been drinking a lot for the past 6 months” following the termination of a long-term relationship.

You are a substance abuse counselor working for a local mental health agency that contracts with the hospital for evening and weekend crisis response calls.

 

Lenora is a 23-yea

QUESTION

Review Case Study 7.2 in the reading. Explore how you as the counselor could
integrate the six-step model of crisis intervention with Lenora.

 

What would be the first
the thing you would do to address this crisis situation?

Understanding of cognitive neuroscience

How can an understanding of cognitive neuroscience make sense of creativity and can it help develop and teach creativity?

Can cognitive Neuroscience explain human creativity?
Cognitive neuroscience studies have confirmed that educational training can improve an individual’s creative thinking. However, not all educational practices in creativity development have been demonstrated to be effective.

 

 

Human hearing ability

Discussion Question on Hearing You already know that our human hearing ability is quite remarkable. You also know that dogs hear "better" than humans.

Perhaps "better" is a poor word choice because dogs simply hear within a different frequency range than humans.

Their hearing ability seems to impress us especially when you think about how dogs are used as service animals, not only for hearing-impaired individuals but also for individuals with specific health concerns.

While dogs (and other animals) hear sounds that humans cannot keep in mind that there are many other sounds in the world that no animal is able to hear.

Here’s an example. When a seed sprouts and pushes through the soil, there’s probably some sound (noise) associated with the seed pod cracking open and the ground moving as the tiny plant emerges.

For this Discussion, list several examples (3 or 4) of events that we ordinarily think of as silent (like the sprouting seed) and assume that your auditory sense (hearing) is able to capture those sounds.

Feel free to include events that take place inside your body as well (i.e., blood flowing through your veins). Please don’t use the examples I have provided. Comment on the benefits and drawbacks, the pros and cons, of having this ability.

Important process in the software development lifecycle

/in /by

Programming Languages (a) Software design is an important process in the software development lifecycle. However, a lot of software developer/house tends to ignore the process. Therefore, provide and explain 2 motivations for software design
b)Two major activities of the software design process include Software Architecture and Detailed Design. Demonstrate how these two activities are being executed.
(1) Do you design software when you “write” a program? What makes software design different from coding?
(2) What is the goal of software design? What would be different if developers went straight to coding without adhering to software design  Suppose that the target virtual machine is stack-oriented and that the stack elements are integer values, and addresses can be stored as integers. Explain which other features are required in such a virtual machine. Invent a simple language of instructions for such a machine and show how it would be used to implement each of the expressions. [10 marks] (c) Suppose that the following rules are proposed as possible optimizations to be implemented in your compiler. expression simplifies to expression (fst e, snd e) → e fst (e1, e2) → e1 snd (e1, e2) → e2
