    An Acoustic Sensor for Airflow in Pediatric Artificial Airways
    Gooty, Vasu; Harris, Charles; Muelenaer, Andre A.; Watson, Brian; Safford, Shawn D. (Elsevier, 2015-01-06)
    Pulmonary hyalinizing granuloma (PHG) is a rare benign pulmonary nodular lesion of unknown etiology. We present a case of a 5-year-old boy who was found to have a chest mass while being evaluated for abdominal pain. He underwent a CXR and CT scan that showed popcorn calcifications in the right posterior mediastinum and within the hilum of right lung. These lesions were suspicious for benign calcified lymph nodes and follow-up chest CT after 3.5 months showed no interval changes in the calcified mediastinal masses. Extensive testing ruled out infectious diseases and malignancies. Given the unknown etiology of the lesions, he underwent VATS biopsy that demonstrated a nodular lesion characterized by a peripheral rim of fibrous tissue and central zone of necrosis and calcification, findings consistent with hyalinizing granuloma. PHG is extremely rare in pediatric age group. Although diagnosis of this condition is made by radiological and histopathological findings, it is important to rule out other causes of chest masses. Most of the patients usually have good prognosis with this rare disorder.

    Domain Engineering: An Empirical Study
    Harris, Charles; Frakes, William B. (Department of Computer Science, Virginia Polytechnic Institute & State University, 2006)
    This paper presents a summary and analysis of data gathered from thirteen domain engineering projects, participant surveys, and demographic information. Taking a failure modes approach, project data is compared to an ideal model of the DARE methodology, revealing valuable insights into points of failure in the domain engineering process. This study suggests that success is a function of the domain analyst’s command of a specific set of domain engineering concepts and skills, the time invested in the process, and persistence in difficult areas. We conclude by presenting strategies to avoid points of failure in future domain engineering projects.
