An Optical Measurement System to Measure Velocity and Provide Shock Wave Pressure Diagrams
This paper introduces an optical measurement system for shock wave characteristics. The system works by mountinga metal plate attached to spring mounts against the shock wavefront. This set is sealed and can plot the shock wave pressure diagram by measuring plate's displacement, radiation and changing the reflection of light during shock wave conflict, and converting these optical data to volta...
متن کاملa generalization of strong causality
در این رساله t_n - علیت قوی تعریف می شود. این رده ها در جدول علیت فضا- زمان بین علیت پایدار و علیت قوی قرار دارند. یک قضیه برای رده بندی آنها ثابت می شود و t_n- علیت قوی با رده های علی کارتر مقایسه می شود. همچنین ثابت می شود که علیت فشرده پایدار از t_n - علیت قوی نتیجه می شود. بعلاوه به بررسی رابطه نظریه دامنه ها با نسبیت عام می پردازیم و ثابت می کنیم که نوع خاصی از فضا- زمان های علی پایدار, ب...
Strong Relativistic Collisionless Shock
A direct numerical simulation of a strong relativistic collisionless shock propagating into an unmagnetized medium has been performed in two spatial dimensions. It is found that: (i) collisionless shock exists, (ii) particle acceleration is insignificant, (iii) the shock does not generate “quasi-static” magnetic fields, contrary to recent claims by other authors. All our results agree with a si...
متن کاملCorrelation of Ultrasonographic Measurement of Inferior Vena Cava Collapsibility Index with Central Venous Pressure in Diagnosis and Management of Neonatal Shock
Background: Neonatal intensive care unit (NICU)Conventionally, Central Venous Pressure (CVP) monitoring has beenused by intensivists to measure intravascular volume. However, it is an invasive procedure resulting in many complications. Non-invasive ultrasonographic measurement of inferior vena cava collapsibility index (IVC-CI) is a promising alternative. Therefore, this study wasconducte...
متن کاملComparison of Various Blood Pressure Measurement Techniques with Standard Office Based Blood Pressure Mesurement
Introduction: In order to control Hypertension, it is necessary to understand the methods of blood pressure measurement. Recent guidelines emphasize on employing appropriate blood pressure measurement techniques and white coat hypertension. Definition and methods of blood pressure measurement have changed in the American guideline based on SPRINT trial (Systolic Blood Pressure Intervention Tria...
