Dynamic, In Situ Measurement of Sea-Ice Characteristic Length
We present a method for measuring the characteristic length of sea ice based on fitting to a the recentlyfound solution for the flexural response of a floating ice sheet subject to localized periodic loading. Unlike previous techniques, the method enables localized measurements at single frequencies of geophysical interest and, since the measurements may be synchronously demodulated, gives exce...
متن کاملSea-Ice Thickness Measurement:
Helicopter-borne electromagnetic (HEM) induction systems provide a means to measure sea ice thickness along flight paths covering a large area in a short period of time, and make the data available in real-time for incorporation into operational ice charts. Ice surface elevation profiles are also collected with a laser altimeter contained in the system. With the introduction of the fix-mounted ...
متن کاملEffects of Slip Condition on the Characteristic of Flow in Ice Melting Process
In this paper a laminar flow of water on an ice layer subjected to a slip condition is considered numerically. The paper describes a parametric mathematical model to simulate the coupled heat and mass transfer events occurring in moving boundary problems associated with a quasi steady state steady flow process. The discretization technique of the elliptic governing differential equations of mas...
متن کاملThe Development of Sea Ice Thickness Measurement Sensor
This paper reports on the development of an acoustic sea ice thickness measurement sensor. The development is applying acoustic NonDestructive-Testing (NDT) techniques to test first year sea ice including significant amounts of enclosed air bubbles. Two single piezoelectric transducers are tightly placed on smoothed sea ice surface to emit and receive acoustic signals. Besides seeing a detectab...
متن کاملIn situ leg length measurement technique in hip arthroplasty.
In situ femoral preparation refers to implanting a femoral component before the femoral neck osteotomy and without dislocating the hip joint, which allows the implanted femoral component to be used to measure leg length and offset. One hundred hip arthroplasty surgeries among 93 patients were compared with a control group of 15 patients. A modular neck femoral component was implanted in a techn...
