An Automatic Multilevel Image Thresholding Using Relative Entropy and Meta-Heuristic Algorithms
Multilevel thresholding has been long considered as one of the most popular techniques for image segmentation. Multilevel thresholding outputs a gray scale image in which more details from the original picture can be kept, while binary thresholding can ...

Oblique Lumbar Interbody Fusion with Selective Biportal Endoscopic Posterior Decompression for Multilevel Lumbar Degenerative Diseases [PDF]
Oblique lumbar interbody fusion is a minimally invasive procedure for treating degenerative lumbar disease. Its advantages include correcting coronal and sagittal spinal alignment and indirect neural decompression. However, achieving a successful outcome

Robustness of Reinforced Concrete Frames against Blast-Induced Progressive Collapse
A quantitative procedure for the robustness and progressive collapse assessment of reinforced concrete (RC) frames under blast load scenarios is presented. This procedure is supported by multilevel numerical models, including nonlinear numerical analyses

Hybrid procedures in treatment of multilevel lesions of the brachiocephalic arteries [PDF]
Background Multilevel significant atherosclerotic disease involving the carotid bifurcation and the proximal ipsilateral common carotid or brachiocephalic arteries presents an uncommon and difficult management problem. Axial (aortocarotid bypass) or extra-anatomic procedures (subclavian–carotid bypass, carotid–carotid bypass, carotid–subclavian ...

MULTILEVEL KOHONEN NETWORK LEARNING FOR CLUSTERING PROBLEMS
Clustering is the procedure of recognising classes of patterns that occur in the environment and assigning each pattern to its relevant. Unlike classical statistical methods, self-organising map (SOM) does not require any prior knowledge about the ...

Posterior surgical options for spondylotic cervical myelopathy
Cervical spondylotic myelopathy (CSM) is a common presentation in the middle-aged to elderly population. The cause of myelopathy is multifactorial, and cervical spondylosis is the most common cause. This review looks into the treatment options, timing of

Equivalent-Capacity-Based Design of Space-Time Block-Coded Sphere-Packing-Aided Multilevel Coding [PDF]
A multilevel coding (MLC) scheme invoking sphere packing (SP) modulation combined with space time block coding (STBC) is designed. The coding rates of each of the MLC component codes are determined using the so-called equivalent capacity based ...

Comparisons of Estimation Procedures for Nonlinear Multilevel Models [PDF]
We introduce General Multilevel Models and discuss the estimation procedures that may be used to fit multilevel models. We apply the proposed procedures to three-level binary data generated in a simulation study. We compare the procedures by two criteria, Bias and efficiency.
