Abstract This paper presents test data of more than 30 vehicles of different manufacturer, weight and front-end length. The relationships between the vehicle frontal NCAP pulse, the dummy response and the vehicle characteristics are shown in many figures. Vehicle frontal pulses were characterized and analyzed by considering different time zones within the pulse duration: bumper effect zone (0 ms. to 5 ms.), engine effect zone (18 ms. to 35 ms.), dummy engagement zone (48 ms. to 68 ms.). Also, ratios and delays between rocker pulse and the dummy chest and head pulses are computed and analyzed. The purpose of this study is not to develop a crash pulse but to generate design information that can assist in the design of front-end structure to meet injury criteria.

This paper reviews the Wideband Power Amplifier (PA) that has been developed since 1990. Several journals had been discussed in this paper covers few topics such as Characterization of Power Amplifiers, Power Amplifier Architecture and Linearization Technique. Advantages and disadvantages of the technique used had been highlighted as well as the summary of those cases been compiled in the table form for comparison purposes. Power Amplifier is one of the important parts in transmitter. However, when involve transistor as an active device, it is important to ensure that the signals are stabilized and transmitted at higher efficiency. This leads to the proposal of a new design of Wideband Power Amplifier based on the concept of the multiplexer.

Information Flow Model

Abstract A study of product development practices at a major consumer product manufacturer, referred to as Company X, was undertaken to compare its methods to an earlier effort in modeling the flow of information in product design, referred to as the Design Information Flow Model. The model considers the recognized need in industry for the seamless capture, storage, and retrieval of design information. The research at Company X focused on the front end of product design, that is, the conceptual phase. It was learned that design, as defined by the Information Flow Model, is well represented at the front end of the company’s design process. However, this validation effort succeeded in uncovering certain voids, particularly in later states of the model. It was also learned that product documentation quality and quantity at Company X vary from project to project, indicating an important aspect to consider in our efforts to enhance computer-aided product design is the user.
