Conceptually, system concept diagrams describe the interaction of a system with its environment. Practically, system context diagrams are recommended for the following phases of IT problem solving: PROJECT PLANNING -- to visually describe initial project scope to system owners, system users, and the project team. This serves as a "visual contract" to manage scope through the remainder of the project. SYSTEM ANALYSIS -- to visually describe requirements for SYSTEM INTERFACES to system users and the project team. SYSTEM DESIGN -- to visually describe technology constraints and decisions for all system interfaces for the benefit of system users, system designers, and system builders. SYSTEM IMPLEMENTATION -- to visually describe conversion requirements for the project team and system owners (not covered in class; and hence, not required in this assignment. This is included here only as a placeholder for course improvement). ASSIGNMENT - Using the UML Context Diagram Profile, develop a full SET of system context diagrams Your system, and hence its context diagrams, must exhibit at least two of the four types of integrating interfaces described and demonstrated in class: user interfaces (also known as human-computer interfaces (HCI) and the user experience (UX) system interfaces (to and from legacy systems) database interfaces (to databases that may be used or update, but whose table structures are considered out of scope) control interfaces (to machines, appliances, or devices -- for "real time systems") Your system must demonstrate all four types if they are applicable to your problem domain. .

The UML was designed as a graphical notation for use with object-oriented systems and applications. Because of its popularity, now it is emerging in the field of embedded systems design as a modeling language. The UML notation is useful in capturing the requirements, documenting the structure, decomposing into objects and defining relationships between objects. It is a notational language that is very useful in modelling the real-time embedded systems. This paper presents the requirements and analysis modelling of a real-time embedded system related to a control system application for platform stabilization using COMET method of design with UML notation. These applications involve designing of electromechanical systems that are controlled by multi-processors.

A complex engineering system such as a xerographic marking engine is an aggregate of interacting subsystems that are coupled through a large number of constraints and design variables. The traditional way of designing these systems is to decouple the overall design into smaller subsystems and assign teams to work on these subsystems. This approach is critical to making the project manageable and enabling concurrent development. However, if the goal is to design systems that can deliver best possible performance, i.e. if the performance limits are being pushed to the extreme, characterizing the interactions becomes critical. Multiobjective optimization is a design methodology that addresses the issue of designing large systems where the goal is to simultaneously optimize a finite number of performance criteria that come from one or more disciplines and are coupled through a set of design variables and constraints. This approach to design makes explicit and quantitative the inherent trade-offs that need to be made in doing coupled system design. It also enables the determination of the attainable limits of performance from a given system. This paper will discuss the multiobjective optimization methodology and optimal methods of performing quantitative trade-off analysis. These design methods will be applied to problems from the xerographic design domain and results will be presented.

Chapter 7: Design: Architecture and Methodology 1 Design Topics Covered Architectural vs. detailed design “Common” architectural styles, tactics, and reference architectures Basic techniques for detailed design Basic issues with user-interface design 2 Design Starts mostly from/with requirements (evolving mostly from functionalities and other non-functional characteristics). How is the software solution going to be structured? What are the main components—(functional comp)? Often directly from requirements’ functionalities (use cases). How are these components related? Possibly re-organize the components (composition/decomposition). Two main levels of design: Architectural (high level) Detailed design How should we depict design—notation/language? 3 Relationship between Architecture and Design Detailed Design Comes from Requirements & Architecture 4 Software Architecture Structure(s) of the solution, comprising: Major software elements Their externally visible properties Relationships among elements Every software system has an architecture. May have multiple structures! Multiple ways of organizing elements, depending on the perspective External properties of components (and modules) Component (module) interfaces Component (module) interactions, rather than internals of components and modules 5 Views and Viewpoints View – representation of a system structure 4+1 views (by Krutchen) Logical (OO decomposition – key abstractions) Process (run-time, concurrency/distribution of functions) Subsystem decomposition Physical architecture +1: use cases Other classification (Bass, Clements, Kazman) Module Run-time Allocation (mapping to development environment) Different views for different people 6 Architectural Styles/Patterns Pipes and filters Event driven Client-server Model-view-controller (MVC) Layered Database centric Three tier We discuss architectural styles/patterns as “reusable” starting point for design activities. 7 Pipe-Filter Architecture Style The high-level design solution is decomposed into two “generic” parts (filters and pipes): Filter is a service that transforms a stream of input data into a stream of output data. Pipe is a mechanism or conduit through which the data flows from one filter to another. Input time cards Prepare for check processing Process checks Problems that require batch file processing seem to fit this architecture: e.g., payroll, compilers, month-end accounting. ** Reminds one of DFD without the data store or source sink.** 8 Event Driven (Real Time) The high-level design solution is based on an event dispatcher, which manages events and the functionalities that depend on those events. These have the following characteristics: Events may be a simple notification or may include associated data. Events may be prioritized or be based on constraints such as time. Events may require synchronous or asynchronous processing. Events may be “registered” ...

Software Archtecture. Software design is a process to transform user requirements into some suitable form, which helps the programmer in software coding and implementation. Software design is the important step in SDLC (Software Design Life Cycle), which moves the concentration from problem domain to solution domain. It tries to specify how to fulfill the requirements mentioned in SRS. Software design plays an important role in developing software: during software design, software engineers produce various models that form a kind of blueprint of the solution to be implemented

Free-style sketching is more natural than drawing a sketch using mouse and palette based tool. A number of sketching systems have been developed but not much attention is paid towards friendliness of the system. We present here an efficient Sketching system MAHII for sketching the strokes from multiple domains. The proposed paper demonstrates how a sketching system can be made user friendly and user interactive too. We also present the architecture of our system that solves many flaws encountered in the previously built systems. The interface should be such that it minimizes the gap between a human being and a machine. Our system provides a robust architecture that proves to be efficient. It also allows the user to sketch the diagram freely. And at the same time it edits the sketches as well as recognizes the sketches efficiently. This paper represents more robust and natural environment to the user. The MAHII provides the user an interface that is built in accordance with a novice user. MAHII provides free style sketching, recognizes the sketch produced by the user with accurate results.

Conflict Resolution at the St. Clare Hospital The St. Clare Hospital was founded in 1988. In the past few years, the revenues have dropped steadily to a point where CEO James Edwards is considering cost control to improve the organization’s bottom line. Mr. Edwards understands physicians play a critical role in controlling cost, but they do not have a great interest in cooperating with him to sustain the viability of the hospital. Mr. Edwards decides to hire Wendy Jones as the chief operating officer and empower her to cut costs for the hospital. The first measure taken by Ms. Jones is to outsource the interpretation of imaging readings and fire the radiologist Dr. Harris. By doing so, the hospital would save $160,000 per year. However, after two weeks, the hospital sees 18% inaccuracy rates in outsourced reading reports. The hospital might face legal liabilities from inaccurate readings. Mr. Edwards and Ms. Jones want to stay with the plan to control costs, but the physicians are furious. The medical director, Dr. Wiseman, gathers all staff physicians to a call for action. Write a four-to six-page double-spaced paper (excluding title and reference pages), addressing the following: Describe types of conflict identified in this case. Explain conflict management styles evidenced in this case. Propose a conflict resolution strategy to be used. Recommend strategies to reduce cost and legal liabilities. .

Resource page (not included in the page count) Resources other than course instructional material must be referenced using APA formatting. The Virtual Criminal Justice Alliance Background For the past 11 months, the Virtual Police Department has applied a variety of investigative resources and strategies and is prepared to bring a number of criminal charges against the members of the Very Bad Bike Club. These started out as investigations of individual calls-for-service, complaints and criminal investigations. They merged into a collective effort as the pattern of activities and participants began to form. Based on the investigations, the department believes it has probable cause to arrest and charge nearly every one of the 63 VBBC members for conspiracy to manufacture illegal drugs, conspiracy to sell illegal drugs, and participation in a criminal enterprise. Additionally, numerous individual VBBC members can be charged with combinations of individual criminal violations, including possession of illegal drugs, illegal possession of firearms, robbery, attempted robbery, aggravated assault, and attempted murder. Despite the confidence the Chief of the VPD has in these cases, no information has been conveyed to the Office of the District Attorney nor has there been any involvement with the Grand Jury. As far as the Chief of the Police is concerned, this is the chance to destroy the VBBC once and for all. The VBBC has plagued Virtual for over a decade. Efforts to stop criminal activity by members of the VBBC have been made almost exclusively by the police department, with little or no support from the rest of the Virtual criminal justice system. In the past most criminal charges brought to the Virtual prosecutor’s office by police detectives have resulted in outright dismissal for lack of probable cause or plea bargained agreements that reduce potential felony charges to misdemeanors with payable fines. There have been however, two prior instances of massive arrests of VBBC members. Approximately 7 years ago raids resulted in the confiscation of drugs and weapons and the ultimate conviction of 12 VBBC members. Six of these members are on parole and still reside in Virtual; two others are currently in the county detention center awaiting trial for new criminal charges and four others are confined to the State prison near Virtual. A similar sweep three years ago produced nearly identical results. These sweeps appear to have been ineffective. In short, the VBBC has a network of .

Conduct a participant observation (ethnographic study) wherein you study through participation in a particular crosscultural group event or social organizational meeting. Samples of events may include a visit to a religious group other than the one you usually attend, hanging out at a greasy spoon café or coffee shop and observing tipping behavior, attending a cross-cultural sporting event (e.g. if you are American, perhaps soccer but NOT American football or baseball), or volunteering with an organization that serves a cultural population somehow different than your own. To complete the assignment paper, first consider what cultural norms may be different from your own and discuss them in writing. Then, participate in the event, writing down your observations, noting any patterns you observe, and pointing out any observations or patterns that particularly surprise you. Why are they surprising to you? What might be the purpose(s) behind the perceived difference? Throughout your paper, you should reflect on your own cultural identity compared to the group being observed. Additionally, you should apply Sociological theory in an attempt to explain multicultural and global diversity 2 to 3 pages long APA Format .

Conduct Disorder The relationship between various Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnoses and criminal behavior has long been examined and debated. One of the more controversial questions centers on the stigma of certain comorbid diagnoses. Conduct disorder is a childhood disorder characterized by aggressive or destructive behavior that significantly disrupts the child or adolescent’s environment—school, home, and relationships. This disorder has long been classified as an early stage in the trajectory of ongoing criminal or antisocial behavior. However, some studies have found that not all individuals diagnosed with conduct disorder go on to commit crimes later in life. There has been concern about labeling youth with a diagnosis of conduct disorder, which is why this is an important topic to understand when working with court-involved youth. Using the readings for this module, the Argosy University online library resources, and the Internet respond to the following: Describe the diagnostic criteria for conduct disorder and other common comorbid diagnoses. Explain the stigma attached to a diagnosis of conduct disorder. Examine how a diagnosis of conduct disorder can impact treatment services provided to youth. Examine whether youth diagnosed with conduct disorder are viewed or treated differently in the legal system. Give reasons for your positions. Support your statements with scholarly references and appropriate examples. Write your initial response in approximately 300 words. Apply APA standards to citation of sources. By Saturday, August 27, 2016 , post your response to the appropriate Discussion Area . Through Wednesday, August 31, 2016 , review and comment on at least two peers’ responses.
