...Systems Analysis and Design (SAD) is an exciting, active field in which analysts continually learn new techniques and approaches to develop systems more effectively and efficiently. In business, SAD refers to the process of examining a business situation with the intent of improving it through better procedures and methods. System analysis and design relates to shaping organizations, improving performance and achieving objectives for profitability and growth. The emphasis is on systems in action, the relationships among subsystems and their contribution to meeting a common goal. Systems development can generally be thought of as having two major components: Systems analysis and Systems design. System design is the process of planning a new business system or one to replace or complement an existing system. System analysis is the process of gathering and interpreting facts, diagnosing problems, and using the information to recommend improvements to the system. This is the job of the systems analyst. A system is orderly grouping of interdependent components linked together according to a plan to achieve a specific objective. Its main characteristic are organization, interaction, interdependence, integration and a central objective. To construct a system, system analyst must consider its elements- input and output, processors, control, feedback, and environment. Systems are classified as physical or abstract, open or closed, and man-made information systems. A system may be schematic...

...T.J. Atoyebi, 2015 ◦ Lecture 7 We all labour against our own cure, for death is the cure of all diseases. —Sir Thomas Browne T.J. Atoyebi, 2015 Although most microorganisms are beneficial and necessary for human well-being, microbial activities may have undesirable consequences, such as food spoilage and disease. Therefore it is essential to be able to kill a wide variety of microorganisms or inhibit their growth to minimize their destructive effects. T.J. Atoyebi, 2015 The goal is twofold: (1) to destroy pathogens and prevent their transmission, (2) to reduce or eliminate microorganisms responsible for the contamination of water, food, and other substances. T.J. Atoyebi, 2015 Control of microorganisms can be achieved by a variety of; physical, chemical and mechanical removal methods. . T.J. Atoyebi, 2015 1. STERILISATION Sterilisation is the process by which all microorganisms present on or in an object are destroyed or removed. Sterilization involves the destruction or removal of all living microbes, spores, and viruses on an object or in an area. Vacuum pump suction T.J. Atoyebi, 2015 Disinfection is the elimination or inhibition of pathogenic microorganisms in or on an object so that they no longer pose a threat.

...3.1 Design of the whole system As mentioned before, safety issue in sharing economy has arouse public’s concern, as robberies or rap cases are reported by media one after another. Because of this, we hope to design a safety system that are able to protect both service providers and receivers’ safety to the greatest extent during the entire service process. In the following, we will take Uber as an example to introduce in detail how this system works in different stages. 3.1.1 Registration When users register an account, they are required to fill in basic personal information and set one or more contact persons. Information integrity contributes to investigation on condition that incident unfortunately happens. Contact person chosen by users can share the users’ location and will receive warning once the users encounter dangers during the service process. Besides, since in most cases, it is service receivers who encounter dangers, service providers will be asked to uploading their police certificate and complete real-name identity authentication by uploading their ID card when register in order to ensure that these providers are credible and reliable 3.1.2 Ride process 3.1.2.1 Passengers A. After passengers place an order, there are two user interaction ---- ① Show the personal information and evaluation about drivers to passengers. If passengers think the evaluation about this deriver is too bad, they have the rights to refuse this service. ② Passengers choose one or more...

...Embedded Systems Design Scott DeCota Modern Operating Systems Embedded systems are all around us. They run the engine, brakes, seatbelt, airbag, and audio system in your car. They digitally encode your voice and construct a radio signal to send it from your cell phone to a base station. They control your microwave, dishwasher, and DVD player. They command robots on a factory floor, power generation in a plant, processes in a chemical plant, and the traffic lights in the city. Embedded operating systems are growing increasingly common in everyday appliances and other devices. These operating systems provide application interfaces for a wide range of different applications. The challenge for developers is to determine which operating system or programming language to use in a particular device or project, and how to utilize the parallelism and concurrency capabilities of the hardware and programming language chosen for a project to design a system of adequate timing precision and efficiency. Developers working with embedded systems need to be extremely diligent in regards to timing and optimization. Embedded systems are frequently interacting with the physical environment in which multiple sources of data may be interacting with the system simultaneously. Developers should have a solid understanding of the parallelism and concurrency capabilities of the hardware for a selected project. These features can occur in different forms that can greatly affect the timing of the...

... The primary role of systems analysts and designers is, of course, to produce a computer system solution to a problem that meets the customer’s requirements. This task can easily be so absorbing in itself that there is seemingly no time left over for thinking about the non-technical issues surrounding the introduction of a new IT system, much less for setting up a people project to address them. So even if the people project is not driven by analysts, designers, or even IT managers, it needs their active support. Many of the tasks carried out by analysts in the early stages of an IT development project have outputs that the people project will need to draw on. For example, the process of creating data models and data flow diagrams may raise questions of data ownership, which need to be fed to the people project to resolve, perhaps through a redefinition of rolesand responsibilities or the introduction of a new procedure. Likewise, if systems analysts have done a detailed assessment of costs and benefits, this will give the people project some idea of the messages they can use to sell the new IT system to users and managers. Analysts can also draw on the people project for valuable help in areas such as human–computer interface design, discussed in Chapter 15. The look and feel of the HCI can be one of the most significant factors in determining a user’s response to a system. The people project can help create the conditions in which HCI design can be done collaboratively...

As regards employment, the philosophy is empowerment combined with high rewards. Company has been lauded by media, but is currently having difficulties with a critical division – Product Data Management. Business Context: CAD (Computer Aided Design) tools have revolutionized product design and workflow processes since their introduction in the early 1970s • Changes design process from two dimensional to three dimensional, significantly reducing design time by eliminating the need to draw product from all angles and modify each drawing every time there was a change • Although systems were expensive at the outset, by 1994 a basic system could cost as low as $7500. • By 1990s the CAD market is segmented. Low price products are also low margin. High end products include additional functionality, eg solids modeling, and retail for up to $75,000 per seat. High end is 25% of the market. High end CAD systems usually required a partner company to integrate and train the purchaser Broader applications were developed off the back of CAD, further streamlining the product design process • Engineering Analyis Tools: computer simulations of testing (eg heat, breakability etc) to detect design flaws earlier and save on costs of real testing. Significantly reduces length of typical product design cycle • Product Data Management: stores...
