Case Study Spiral model Spiral model for software engineering combines the best features of the classic model life cycle and prototyping. But also adds new features that are not included in the other models, such as risk analysis. The spiral model defines four main activities for the lifecycle. †¢ Planning: Determining project objectives, alternatives and constraints. †¢ Risk analysis: The analysis of alternatives and the identification and solution of risks. †¢ Engineering: Product development. †¢ Customer rating: The agreement of the results of engineering. The model is represented by a spiral divided into four quadrants, each described in the above activities. The spiral model uses an iterative development scheme where the first iteration begins in the center of the circle and, incrementally, is moving out. The following successive iterations are more complete software being built versions.

An Analysis of Chimes of Silence Wole Soyinka is a Nigerian playwright, and the author of the prose poem Chimes of Silence Essay Example For Students

An Analysis of Chimes of Silence Wole Soyinka is a Nigerian playwright, and the author of the prose poem Chimes of Silence Essay Wole Soyinka is a Nigerian playwright, and the author of the prose poem Chimes of Silence. In order to describe his experience in solitary confinement Soyinka uses descriptive language involving his vision to better enlighten the reader to his experience. The most dramatic passages in Chimes of Silence describe his limited vision, which expresses to the reader how difficult and horrible of an experience it must have been. Soyinkas efforts to see any sign of life through peepholes in order to have some way of connecting with the outside world, shows just how lonely he really is. The poem opens with Soyinka struggling to see through a peephole in the door of his cell. His interest in the boring details outside of his cell shows just how lonely he is, and how much he longs to have any kind of contact with reality. A little square hole cut in the door, enough for a goalers fist to passà ¢Ã¢â€š ¬Ã‚ ¦enough for me toà ¢Ã¢â€š ¬Ã‚ ¦steal a quick look at the rare flash of a hand, a face, a gestureà ¢Ã¢â€š ¬Ã‚ ¦140. Soyinka is desperate to see anything that he can relate to human life. Anything that assures him that even though he has no contact with humans that life is still going on. Anything that reminds him that theres the possibility that he could one day enter back into the life that he has been exiled from. Soyinka continues describing things he strains to see thorough the peephole including, à ¢Ã¢â€š ¬Ã‚ ¦more often a blur of khaki, the square planted rear of the guard on the other side 140. Not only does Soyinka strain to see any part of the human body i tself, but also anything else that reminds him of human beings. Something we take for granted everyday Soyinka finds as a connection to the outside world. Its clear through his description of vision seeing through the peephole that Soyinka is desperate for human interaction and is clearly very lonely. Later in the essay Soyinka makes reference to the limited but present amount of sky that he is able to see in his cell; à ¢Ã¢â€š ¬Ã‚ ¦a sky the size of a napkin trapped by small spikes and broken bottles, but a sky 140. Through his describing the sky Soyinka finds another way of connecting to the outside world. The sky that he looks upon is the same one that people look upon everyday, and to him it makes the correlation to the human life he longs to be living. Soyinka knows that when he was once living and surrounded by human contact that he was covered by the same sky that he sees in his cell. It serves as a reminder to him that although trapped he can still carry a piece of his old life within him. His memories of his old life can help make up for the emptiness inside of him in his time of being alone. Soyinka also describes the birds he can see from his cell, Vultures  perch on a roof just visible from another yard. And crows. Egrets overfly my crypt and bats swarm at sunset 140. Through his description of the birds Soyinka once again describes something living in order to make up for the fact that he feels so alone, and in a sense dead. It seems that in Soyinkas description of the birds that he almost longs to be them, to be able to fly and be free. Soyinka envies the birds for they arent trapped alone and they have access to the world unlike him. .u345e382405472e8e4011922826b1655d , .u345e382405472e8e4011922826b1655d .postImageUrl , .u345e382405472e8e4011922826b1655d .centered-text-area { min-height: 80px; position: relative; } .u345e382405472e8e4011922826b1655d , .u345e382405472e8e4011922826b1655d:hover , .u345e382405472e8e4011922826b1655d:visited , .u345e382405472e8e4011922826b1655d:active { border:0!important; } .u345e382405472e8e4011922826b1655d .clearfix:after { content: ""; display: table; clear: both; } .u345e382405472e8e4011922826b1655d { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u345e382405472e8e4011922826b1655d:active , .u345e382405472e8e4011922826b1655d:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u345e382405472e8e4011922826b1655d .centered-text-area { width: 100%; position: relative ; } .u345e382405472e8e4011922826b1655d .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u345e382405472e8e4011922826b1655d .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u345e382405472e8e4011922826b1655d .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u345e382405472e8e4011922826b1655d:hover .ctaButton { background-color: #34495E!important; } .u345e382405472e8e4011922826b1655d .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u345e382405472e8e4011922826b1655d .u345e382405472e8e4011922826b1655d-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u345e382405472e8e4011922826b1655d:after { content: ""; display: block; clear: both; } READ: So different from other poets during her century. EssaySoyinka eventually discovers a new peephole in his cell and once again he strains to see anything he can to keep himself from being so lonely. Soyinka talks of counting feet walking by in order to keep some kind of reality And now feetà ¢Ã¢â€š ¬Ã‚ ¦the procession goes by and I count 141. By counting the feet Soyinka can establish the slightest relationship to any kind of outside life. Its almost as if by counting the feet Soyinka can relate to the prisoners and make up for the emptiness he is feeling, and not seem to be so alone. Although they arent trapped there with him the routine of having them be there at the sam e time everyday makes it seem as though he isnt so alone and he can look forward to them being there to make everything easier for him. At the end of the essay Soyinka describes a hallucination that he sees in his head; à ¢Ã¢â€š ¬Ã‚ ¦a boys face! A guileless hunter unmasks, in innocence-an evil labyrinth 141. Soyinka apparently eventually has a nervous breakdown despite his attempts to keep it from happening by making any kind of human relation. This goes to show just how lonely Soyinka became after lack of human contact and communication. The key to Soykinas vision is the fact that it involves people and faces things he was so desperately trying to see before. In the end his efforts to see prove ineffective and he apparently loses it completely. After reading Chimes of Silence it becomes quite clear just how lonely a person in solitary confinement might be. We begin to understand why Soyinka treasures the limited sight that he has in order to keep his sanity. We realize the loneliness that is so much a part of his world. It goes to show that vision is extremely important and that although maybe it didnt prove very successful in helping keep Soyinkas sanity it definitely helped him to be able to postpone it a little longer than it would had he not been able to see at all.
