Specification The example specification shown opposite has been written for a project regarding designing a small electronic/mechanical toy for young children. 1. The specification should be composed of simple, clear statements. Keep the statements as short as possible. 2. If possible, always refer to the research you have carried out. For example, “The colour scheme will be based on blue and red as these colours are the most popular - as seen in my questionnaire”. 3. Look at each page of your research and try to write a statement based on each one.

Modeling Requirements with SysML: How modeling can be useful to better define and trace… - Requirements Engineering Magazine This article will explore in depth the specific constructs proposed by SysML (as compared to UML) to model both requirements and traceability. We will see how the Requirement diagram enables the capture of requirements hierarchies and derivations, and how the “satisfy” and “verify” relationships allow a modeler to relate a requirement to either a design element that satisfies it or a test case that verifies it. We will also give practical recommendations on how to best use these particular modeling constructs. 1. What is SysML?

Design Process Index Page If you are to get a high grade you must put effort into this section. Remember, all research must be relevant to your project and constantly refer to the problem you are trying to solve. Produce at least one sheet on each of the following: Suitable materials for your project. Investigate the ways in which materials can be joined together - joints and fixings. Dielectrics the basic idea Dielectrics are insulators, plain and simple. The two words refer to the same class of materials, but are of different origin and are used preferentially in different contexts.

Example Design Spec The full specification is presented here or you can look at individual sections by following the links below. Contents 1. Background information A number of software programs for the BBC micro ( ) have been developed for use in primary schools, but due to the unfamiliarity of the QWERTY keyboard layout and the small size of keys in relation to children's dexterity, the application and acceptance of this software has been limited. A keyboard converter, using larger keys with clearly defined functions, was designed to overcome the problems caused by a compact, complicated keyboard.

Series and Parallel Circuits Section 19.1 Series circuits A series circuit is a circuit in which resistors are arranged in a chain, so the current has only one path to take. The current is the same through each resistor. The total resistance of the circuit is found by simply adding up the resistance values of the individual resistors: equivalent resistance of resistors in series : R = R1 + R2 + R3 + ...
