Presentation Transcript

  1. Topics 2/1/2011 • Technical Analysis Papers • Proposal • Microsoft Word and Project

  2. Tech Analysis: What’s Missing • Technical Analysis and design Requirements • Many papers did not define Requirements • Example: Computer power supply

  3. Resubmission • If you received a lower grade, and would like to resubmit, do so by Monday, 11:59 PM. • The final grade will be 1/3 the first grade, and 2/3 the second grade • Check yourself against the rubric; This would have saved you much trouble.

  4. Citation and Writing • Copy-Pasting a link is not a citation. It’s a pasted hyperlink • APA, MLA, IEEE, Chicago citation formats • New writing rubric posted

  5. Proposal: Chapter 6 • Formal Presentation of the technical approach you plan to use to solve problems • Presents a task plan, schedule, work breakdown (who does what), and estimated cost analysis • Examine Description (online) • Examine Rubric (online)

  6. Design Philosophy • What is the overarching idea of the design: Do you want it cheap, robust, C+ get out of here level • On a philosophical basis, this will affect your design decisions • This also impacts your budget

  7. Abstracts: Chapter 12 • We use Informative Abstracts, not descriptive • Condense the information of a report to a few sentences, contain the substance, not just the outline • Compare some examples

  8. “Say Something” Abstract: a detailed summary of what is contained in the work Descriptive: In this paper, I will discuss the use of voltage only measurement to locate faults. This approach is extremely useful for locating faults. This works better than many other methods, and uses an advanced signal processing technique to accomplish our goals. In the first section I will introduce my topic, and some of the reasons why we need another fault location method. Next I will explain the theoretical aspects, then I will show the simulation data. Finally I will conclude with real-world data, that shows our method is successful. Informative: A travelling wave approach using voltage-only measurement is used to locate faults to within 1.5% of the line length. Our method is a double-ended approach, and unlike traditional travelling-wave methodologies, it does not rely on expensive GPS-synchronized recordings. For each end of the line, the travelling wave oscillation frequency is determined using Cohen’s class of time-frequency analysis, and using the ratio of these frequencies, the distance to the fault from each recorder is determined. The accuracy of our methodology is validated using an ATP fault model, as well as COMTRADE data from several real-world cases.

  9. Informative vs Descriptive Abstract: a detailed summary of what is contained in the work Informative: This proposal provides information describing our solution to the implementation of the Photonic Cannon, a type of bug zapper. This implementation of a bug zapper will include a microphone array to track the position of the bug on a one by one meter square surface. The microphone array will be fixed to the platform with the laser to reduce error. Filtering and analysis will be done by a low impedance amplifier, Butterworth filter, and LC resonant filter tuned at 1 kHz. The DSP chip, dsPIC30f4012, will analyze the phase relationship between the microphone arrays using cross correlation technique and pinpoint the location of the bug. It will then command servo motors to position a laser to zap the bug. The end result will allow the system to track the bug as it moves across a surface at a speed of one meter per second at a distance one meter away. Initial findings of components estimate the total budget to be $412.64 and be completed by December 3, 2010. Descriptive: This document will outline a clear design philosophy & concept, including task delegation and organizational structure. Included is a clear definition of the team’s goals for this project, as well as a breakdown of the system’s modular design and how it will fulfill the requirements set forth from the assignment specifications. Also, a budget and schedule is included with estimates of the monetary and time constraints to illustrate the feasibility of completing this project.

  10. “Say Something” • In your work, get right to the point • There is no need to introduce your introductions • Quantitative explanations are more valuable than qualitative: • “The energy required to transmit the signal is very large.” • “The energy required to transmit the signal 5m is 300 mW.” • Pictures are useful because they can convey more information than simply numbers or sentences.

  12. Plagiarism Revisited From Martin 2004, p. 372 If I Wrote: A microphone is one of a few devices used in audio that can be called a transducer. Generally speaking, a transducer is some device that converts between one kind of energy to another, like from mechanical to electrical energy (Martin 2004). This is considered plagiarism, because I’ve taken what he’s said and copied it almost exactly. Even if I reference it, it is still plagiarism because I have copied it directly: it is a Quotation. There are other options.

  13. Documentation: Plagirism From Martin 2004, p. 372 Option: Paraphrase A microphone is one of several devices known as transducers. The microphone is one of the most common transducers in the realm of audio. Transducers are devices which convert energy between different types of energy, such as from mechanical to electrical (Martin 2004). Option: Block Quote: “A microphone is one of a small number of devices used in audio that can be called a transducer. Generally speaking, a transducer is any device that converts one kind of energy into another (for example, electrical energy into mechanical energy.)” (Martin 2004)

  14. Microsoft Project • Useful for organizing projects • Free in the computer labs • Cheap from MSDN Alliance • Example: Building a computer

  15. Microsoft Word • Styles make changing formats easy • Templates are great for designing professional documents • Track changes, Comments, and collaboration are made easy by MS word
