DETERMINING THE PROBABILITY OF THE VISUAL DETECTION OF SINK MARKS ON DIFFERENTLY TEXTURED INJECTION MOLDED PRODUCTS
eBook (PDF): $0.00
This doctoral dissertation studied the effects surface texture and color have upon the visual detection of sink marks. Human observers evaluated a series of injection-molded parts exhibiting various... More > sink marks dimensions as well as various textures. Data were collected in the Plastics Processing Laboratory at Western Michigan University’s Parkview Campus and at various plastics companies located in western Michigan. The results of the research confirmed industry-held beliefs in the effectiveness of surface texture to conceal minor sink marks. The color of the sample plaques was found to be a significant contributor to the probability of the perception of a sink mark. The research also found that the environment surrounding a sink mark could influence the probability of visually detecting the sink mark. Factors essential for predicting sink mark visibility were identified, allowing the development of models for designers to use to eliminate the visibility of problematic sink marks.< Less

HCCI Engine Control and Optimization
eBook (PDF): $0.00
Homogeneous charge compression ignition (HCCI) engines have the benefit of high efficiency with low emissions of nitrogen oxides and particulates. These benefits are due to the autoignition process... More > of the dilute mixture of fuel and air during compression. However, because there is no direct ignition trigger, control of ignition is inherently more difficult than in standard internal combustion engines. This dissertation addresses some the control issues of HCCI engines.< Less
Aircraft Accident Investigations
eBook (PDF): $6.25
This paper takes a look at the aircraft accident investigations that are undertaken when an airplane suffers an accident. Airplanes are complex machines and there can be many behind an airplane... More > disaster. As a result of international cooperation and the stringent standards of engineering testing that is required in international civil aviation, flying is the safest form of transportation that is available. However, accidents do happen and not all accidents are the result of terrorists attempting to destroy an aircraft. Fuel leaks, metal fatigue, engine fires as well as pilot error can cause accidents. Criminal investigations are only conducted if there is evidence of deliberate attempts to destroy an airplane. This paper takes a look at the investigations that are conducted after an aircraft accident.< Less

Using Math to Defeat the Enemy: Combat Modeling for Simulation
eBook (PDF): $20.00
This book was written for the 2nd Annual Modeling and Simulation Summit, Pre-Conference Focus Day Workshop: Using Math to Defeat the Enemy: Combat Modeling for Simulation (Monday, August 29th... More > 2011). Although mathematics is key to combat model for simulation, this book provides just a cursory survey of mathematical model, and includes heuristics and other algorithms. The book covers behavior models, environmental models, communication models, target detection models, attrition model, entity and aggregate level models, and multi-resolution models. It provides examples of past and current model, simulations, and wargames to stimulate learning and discussion.< Less
