As we mentioned in the introduction section, one of the time problems related to the Tableau procedure is checking if the branch is closed or not. The ordinary way for checking if a branch is closed is known as highly time-cost process. We need an intelligent and simple way to construct and check the branches. One way, is to use ordered branches (i.e. to put the negated predicates in the branch first, and then not negated ones), but we still have a problem if the number of negated elements is much

supply. Forest soil is moist, this is due from tree coverage, blocking out the sun. Consequently, removal of the trees causes the soil to dry out (National Geographic). Trees perpetuate the water cycle by returning water vapor back into the atmosphere. Tree roots greatly stabilize both soil and water, without these roots, water quickly washes away the soil, carrying many nutrients and minerals with it. Deforestation also causes water pollution. Tree roots not only hold the soil in place but help

of the past, I looked at the tree, suddenly hit by nostalgia. In a moment of clarity, I realized the significance, the representation, the resemblance between the tree and I. As the pure white snowflakes danced across the clear blue sky, the tree, now naked and exposed in front of me, exemplified my own self. I couldn’t hide from the truth; I couldn’t hide behind the vibrant colors of my life, I couldn 't hide and live life the way I had been before. Just like the tree, who needs sunshine to grow

My definition for home is indescribable by word or by a simple thought, but home is rather of a feeling. Home is the calmness and serenity that settles over me like a blanket on a cold,snowy night, just a silent assurance telling me I belong there. It took me quite a bit of time to understand where exactly that place is, and I didn’t know that the answer was always right in front of me. This feeling would come and go, and I would never recognize it because I knew that only the house I lived in was

The legend of Johnny Appleseed developed from the historical account of John Chapman because the two characters have many similarities in their traits and their journey. Basically, Johnny Appleseed and Jonathan Chapman are the same people, but the legend exaggerates his character traits, and the historical accounts state the facts about him.

One of Billy's biggest conflicts is when his dogs tree a coon in a very large tree. Bill knows this tree as “the big tree”, the one that is impossible to climb let alone cut down. As said on pg 78 of Where The Red Fern Grows, “I know he’s there,” I said, “but there’s nothing I can do. I can’t climb it. Why it's sixty feet up to the first limb and it would take me a month to cut it down.”(Rawls) Billy struggles with being able to climb the tree because he feels that he will not be able to because

November air wisped past my ivory skin as I strolled through the neighborhood. I stepped off of the cracked sidewalk so I could turn on to the next street, but a seven-foot-tall metal pole with an octagon challenged me at the sharp corner. The top of the vibrant red sign had an emerald rectangle attached to it that read “S BARWICK PL” in white text with the same colored border. The word “STOP” that was written in the middle of the geometric shape was meant for passing cars, felt like it was meant

loud voices. This perplexing place came straight out of the children’s shows The Jetsons, with the high-speed trains and dazzling advertisements. I could not wait to see the tropical paradise that waited for me, with toucans and monkeys going from tree to tree and all kinds of exotic birds chirping at each other. Once we arrived, I stepped off the bus to our first hotel. I could not help but feel overwhelmed with disappointment. The tropical paradise I expected did not exist. Instead, with sidewalks
