Spiral Case Studies Samples For Students

Software Engineering Life Cycle Models

In software engineering, a life cycle model is a framework that describes the activities that will be carried out during each phase of software development project. The discussion will focus on five software development models namely: the waterfall model, the spiral model, the v-shaped model, the iteration model, and the structured evolutionary prototyping model.

The Waterfall Model

This model is linearly sequential, resembling a series of cascades. It involves the following phases; establishing requirements, designing, implementation, testing, installation and maintenance. Each stage of this model produces a deliverable that is required by the next phase and the deliverable has to be completed before beginning the next ...

The world over, countries look forward and tirelessly work toward improving their economies. A growth in the economy signifies an improvement in the standards of living improved gross domestic product (GDP). In the last three decades, the Middle East has generally experienced tremendous growth in their GDP and with specific emphasis to Japan and China which have grown to be global economic powerhouses (Otsuka, 2011). However, a down spiral has been experienced as regards to the rate of economic growth in the past two decades as a result of economic stagnation experienced by Japan since the burst of the asset price ...

Chapter 7 – Listening (19 questions)

1. Percentage that listeners remember after hearing a message
Right after hearing a message only about 50% of people remember the message. Within 8 hours the 50% drops to 35%, after 2 months only 25% remember the original message. (Page 241)
2. Listen more than any other type of communication
3. Questioning and paraphrasing
These are two techniques that show a speaker the listener is attentive. They also help the listener make sure he/she understands what the speaker is trying to say. They need to be learned and practiced to do well.

Invented and patented by Thomas Edison in 1879, the incandescent bulb comprises of a wired filament placed inside a glass bulb (“The History”). When electricity is provided to the filament, it heats up thereby making the bulb glow and emit light (“Incandescent, LED”). The wired filament of the incandescent bulb was initially made using carbon obtained from a cotton thread that was uncoated. This filament gave the bulb a lifespan of just 14.5 hours. Later, the carbon filament was made using bamboo, which gave the bulb a longer lifespan of up to 1200 hours (“The History”). Much later, in ...

Abstract

This paper seeks to examine what constitutes artificial intelligence, the principles behind it, its application, and the cases whereby artificial intelligence has proved to be a success. On a broad scale, this paper finds that artificial intelligence is a relatively new field, but its outcomes are promising. Creators of artificially intelligent systems aim to make machines capable of making independent decisions, and artificially intelligent objects heavily rely on agents to be able to make the independent decisions. Artificial intelligence is widely applied in various fields such as medicine, banking and the video gaming industry among others. Future forecasts prove that artificial intelligence ...
