A new theory of hydrodynamics of uniaxial nematic liquid crystal films in the presence of defects is developed. A gauge field incorporating screening is introduced, resulting in the static elastic free energy having the form of a two-dimensional Abelian-Higgs model. Hydrodynamic equations are derived via the standard methods of de Groot and Mazur. By working in the vicinity of the Bogomol’nyi e...

In practices, not only production but inspection processes are often not perfect, thereby generating defects and inspection errors. Previous imperfect-quality inventory studies, however, have mostly focused on developing cost-minimizing models that do not consider imperfect inspection processes and related defect sales return issues despite their practical significance. Thus, this study propose...

Background: Existing software defect classification schemes support multiple tasks, such as root cause analysis and process improvement guidance. However, existing schemes do not assist in assigning defects to a broad range of high level software goals, such as software quality characteristics like functionality, maintainability, and usability. Aim: We investigate whether a classification based...

Background and Aim: Neurofibromatosis-1(NF-1) is a common genetic condition in children. It is becoming increasingly recognized that in neurofibromatosis, there might be anomalous development of bone with or without any local anomaly of neuro-ectodermal basis. This review was conducted to highlight the different features of spinal disorders in this congenital disease. Methods and Materials: Di...
