Age Estimation Methods In Forensic Odontology, Phuwadon Duangto, Apirum Janhom, Sukon Prasitwattanaseree, Pasuk Mahakkanukrauh, Anak Iamaroon Dec 2016

Age Estimation Methods In Forensic Odontology, Phuwadon Duangto, Apirum Janhom, Sukon Prasitwattanaseree, Pasuk Mahakkanukrauh, Anak Iamaroon

Journal of Dentistry Indonesia

Age estimation, using forensic odontology, is a crucial step for biological identification. Currently there are many methods available to predict the age of deceased or living persons, each with varying accuracy, such as a physical examination, radiographs of the left hand, and dental assessments. Age estimation, using radiographic tooth development, has been found to be a more accurate method because it is mainly genetically influenced and as such is less likely to be affected by nutritional and environmental factors. The Demirjian et al. method for dental age estimation, using radiological techniques, has long been the most common protocol used in …

Benefits Of Ethanol Based Noni Leaf (Morinda Citrifolia L.) Extract On Oral Mucosal Wound Healing By Examination Of Fibroblast Cells, Indah Pr Sabirin, Euis R. Yuslianti

Journal of Dentistry Indonesia

Wound healing is a biological response that occurs following a trauma or pathologic condition of the oral mucosa. Wounds require proper management so they may heal faster and without complication. The number of fibroblast cells seen in the oral mucosa is a strong indicator of wound healing. In the remodelling phase of wound healing, fibroblast cell proliferation decreases as collagen fibres are synthesized. Noni leaf (Morinda citrifolia L.), a part of the noni plant, is traditionally used to heal soft tissue wounds in Indonesia. The leaves have potential chemical compounds that may be useful in the wound repair process. Objective: …

Advancing Nasa’S Airmoss P-Band Radar Root Zone Soil Moisture Retrieval Algorithm Via Incorporation Of Richards’ Equation, Morteza Sadeghi, Alireza Tabatabaeenejad, Markus Tuller, Mahta Moghaddam, Scott B. Jones

Plants, Soils, and Climate Faculty Publications

P-band radar remote sensing applied during the Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) mission has shown great potential for estimation of root zone soil moisture. When retrieving the soil moisture profile (SMP) from P-band radar observations, a mathematical function describing the vertical moisture distribution is required. Because only a limited number of observations are available, the number of free parameters of the mathematical model must not exceed the number of observed data. For this reason, an empirical quadratic function (second order polynomial) is currently applied in the AirMOSS inversion algorithm to retrieve the SMP. The three free parameters …

A Slic-Basedsuperpixel Segmentation Method By Using Local Texture Features For Granular Image, Li Xiaoyu, Zhang Qiuju Dec 2016

A Slic-Basedsuperpixel Segmentation Method By Using Local Texture Features For Granular Image, Li Xiaoyu, Zhang Qiuju

Food and Machinery

This paper adopts SLIC-based superpixel segmentation method in the granular image detection. SLIC method segments the granular image into superpixel block which will reduce the complexity of the subsequent image processing. As SLIC superpixel segmentation method doesn’t use the texture feature in the distance calculation, the detail of the outline for the granular object is lost. This paper adopts the CRLBP local texture operator as the texture feature to improve the SLIC segmentation’s distance calculation and searches the similar pixel in circle neighborhood pixels to guarantee the processing speed. The test on cotton seed image shows that the improved SLIC …
