  • Dana Point Case Study

    composition (mostly sedimentary) and high erosion rates from the sea but become increasingly stressed from overlying man-made structures and landscaping practices. For this reason, it is important to continually monitor the geological hazards that exist along the coast. One relatively new way to monitor landscape changes over time is by the use of three-dimensional (3D) mapping. Long-term changes can be seen by…

  • Essay On Bipolar Stepper Motor

    1. Introduction This is the first in a series of articles on using Forth to interact with the real world. We will explore how to control motors of various types (such as servomotors and stepper motors), switch power to devices, and sense the environment. Each article will present a project that can be used to demonstrate the ideas we are going to discuss. In this first article, I want to lay the foundation for the future columns and discuss the use of the PC parallel port to control…

  • Technology: The Invention Of 3D Printing

    due to desensitization. Inventions we consider essential and routine such as the radio or television caused an uprising when first introduced to the public in the 1900’s. For Americans living in the early 20th century, the invention of three dimensional (3D) printing would have certainly created havoc. Considering the fact that computers and technology leading up to 3D printing were still in the works, it would be surprising if people were not…

  • Photometric Stereo Advantages And Disadvantages

    1. ABSTRACT The essence of an image is a projection from a 3D scene onto a 2D plane, during which the depth information is lost. The 3D point corresponding to a specific image point is constrained to be on the line of sight. From a single image, it is very difficult to determine the depth information of various object points in an image. If two or more 2D images are used, then the relative depth point of the image points can be calculated which can be further used to reconstruct the 3D image by…

  • Essay On How Technology Has Changed Health Care

    criticized for the potentially harmful effects of those innovations. Today, x-rays are used when you go to the dentist, when you break a limb, or when you go for a diagnoses among other things. Although when x-rays first came out there was a lot of concerns about any possible side effects the radiation might cause. According to the FDA some of the risks from getting an x-ray are the possibility of developing cancer later on in life, hair loss, skin reddening, and cataracts though it all depends…

  • Stepper Motor Case Study

    Question 3: a) What is the main use of stepper motors? In essence, stepper motors are applied in motion-control positioning system. For instance in 3D printers, disk drives, intelligent lighting, scanners, CNC machines, printers, camera lenses, plotters and slot machines. b) What are the similarities and differences between a reluctance, a permanent magnet and hybrid stepper motors? The three motors are similar in that, they all have power electronic control that comes with electronic…

  • 3d Printing Essay

    3D Printing and the Additive Manufacturing Process Additive manufacturing (AM) is a process where an object is created by adding layer-upon-layer of material. This basic process requires the use of a computer, CAD software, the material(s) and the appropriate machine to fabricate the end result. AM has been used in many applications. At first, it was used in Rapid Prototyping (RP). Today, AM is used to create end-products used in many different applications, from aerospace, automotive and…

  • Physical Characteristics Of 3D Printers

    problem statement investigates the ability to connect a 3D printed model to the 3D printer used for its production. The main objective focused on identification of physical characteristics of the 3D printed model that are caused by a specific 3D printer parameter. Two 3D printers were utilized in this research. The first is a Printrbot 3D printer (model 1404) running Marlin Firmware (version: 1.0.0 bedlevel metal- simple). The software used to communicate with the Printrbot 3D printer is…
