The article introduces the design of the half-bridge switching and regulated power supply system which is based on PWM. The design mainly consists of regulated power supply’s structure of basic hardware circuit, its working principles and the process of modeling simulation and software design. The control circuit controls SG3525 chip to output PWM wave through the Microprocessor Control Unit (MCU) of AT89C51 and drives IGBT through the chip of EXB841 as well. The MCU is also used to realize the keyboard process and controls of the pulse width and frequency. Taking advantage of Simulink (dynamic simulation Toolbox) and SimPowerSysterm (power simulation Toolbox) of MATLAB, it simulates the designed regulated power supply. According to the simulation result of this design, the system has high stability and good output waveform. The operation of the design is simple and clear with less software operation and higher speed.

Kaupapa Māori

We describe a collaboration between Māori (Indigenous people of Aotearoa/New Zealand) and Tauiwi (non-Māori) researchers on a software engineering project. Te Tiriti o Waitangi (The Treaty of Waitangi) provides the basis for Māori to lead research that involves Māori as participants or intends to impact Māori outcomes. Through collaboration, an extension of the traditional four-step software design process was created, culminating in a nine-step integrated process that included Kaupapa Māori (Māori ideology) principles. The collaboration experience for both Māori and Tauiwi highlighted areas of misunderstanding within the research context based on differing worldviews and our ability to navigate and work through this. This article provides context, guiding principles, and recommended research processes where Māori and Tauiwi aim to collaborate.

Organization Quality

Software design decisions are usually made at early stages but have far-reaching effects regarding system organization, quality, and cost. When doing design, developers apply their technical knowledge to decide among multiple solutions, seeking a reasonable balance between functional and quality-attribute requirements. Due to the complexity of this exploration, the resulting solutions are often more a matter of developer’s experience than of systematic reasoning. It is argued that AI-based tools can assist developers to search the design space more effectively. In this chapter, the authors take a software design approach driven by quality attributes, and then present two tools that have been specifically developed to support that approach. The first tool is an assistant for exploring architectural models, while the second tool is an assistant for the refinement of architectural models into object-oriented models. Furthermore, the authors show an example of how these design assistants are combined in a tool chain, in order to ensure that the main quality attributes are preserved across the design process.

Front Office

The software industry really came of age in the 1970s and 1980s. This was a time of technological transformation in the workplace. The computer expanded from the backroom to the front office and evolved from simple data processing to integrated information systems. The growth of the independent software vendor led to an important change in software design. User firms began to purchase large, standard or semicustom systems from thirdparty vendors rather than purchasing software with hardware and having most applications software custom designed by an in-house programming staff. This added another dimension to the software design process: Software became the product of at least two organizations (the vendor and one or more user firms) and its design and production became mediated by the market. The organizational simplicity of software design occurring within one organization, as difficult a process as that may be, became relatively more complex organizationally. This chapter examines one part of the process of technology design and use: the activities internal to the software design firm. It concentrates on the structure and dynamics of the design process rather than on specific design decisions. The findings presented in this chapter are based on a survey of vendor firms and may represent a different perspective than findings on software developed within a user firm. By focusing on dynamics that transcend choices of particular individuals, we show how decisions are shaped and constrained by the structure of the design process itself. The three chapters following this one present case studies that describe specific choices of software features and functions and analyze the impacts of those choices on software users and customers. Taken together, this chapter and the case studies present the dual perspective necessary to appreciate how software is a socially constructed technology. The business applications software industry for mainframes and minicomputers is composed of hardware manufacturers such as IBM and Digital Equipment Corporation, several large vendors, and numbers of small specialty firms.
