The economic crisis and the COVID-19 pandemic since 2019 forced both public private schools in Lebanon to close for an extended period of time. Many topics were suspended from curriculum due decreasing number learning days. predominant causes loss are lengthy gaps or cutouts students’ education. This study aims investigate impact school closure on learning, specifically biology at secondary lev...

The increasing trendof constructing componentsmade of composite laminates is due tothe flexibility intailoring their properties and high strength-to-weight ratio. Nevertheless, most practical components involve cutout features for fastening these cutouts could significantly reduce the strength laminate. Due to its importance, many studies were conducted study effect circular however, there lack...

With the onset of large-scale astronomical surveys capturing millions images, there is an increasing need to develop fast and accurate deconvolution algorithms that generalize well different images. A powerful accessible method would allow for reconstruction a cleaner estimation sky. The deconvolved images be helpful perform photometric measurements help make progress in fields galaxy formation...

BACKGROUND Fractures of the intertrochanteric hip are common and the treatment of unstable fractures generally requires an operative approach. In elderly patients, osteoporosis makes internal fixation problematic and frequently contributes to failed fixation and poor clinical results. We have attempted to apply the Less Invasive Stabilization System (LISS) in reverse position for the repair of ...

A 3D modeling system with all-inclusive functionality is too demanding for a casual 3D modeler to learn. There has been a shift towards more approachable systems, with easy-to-learn, intuitive interfaces. However, most modeling systems still employ mouse and keyboard interfaces, despite the ubiquity of tablet devices and the benefits of multi-touch interfaces. We introduce an alternative 3D mod...

This paper introduces the video mesh, a data structure for representing video as 2.5D “paper cutouts.” The video mesh allows interactive editing of moving objects and modeling of depth, which enables 3D effects and post-exposure camera control. The video mesh sparsely encodes optical flow as well as depth, and handles occlusion using local layering and alpha mattes. Motion is described by a spa...

A posteriori estimation of defeaturing error. i.e. engineering analysis error caused by defeaturing, remains a key challenge in CAD/CAE integration; indeed, it is essential if analysis based on automatic simplification of the geometry of a complex design is to be reliable. Previous work has mainly focused on removing a single, negative, internal design feature (i.e. a void within the model’s in...

Study Design Biomechanical analysis of lateral mass screw pullout strength. Objective We compare the pullout strength of our bone cement-revised lateral mass screw with the standard lateral mass screw. Methods In cadaveric cervical spines, we simulated lateral mass screw "cutouts" unilaterally from C3 to C7. We salvaged fixation in the cutout side with polymethyl methacrylate (PMMA) or Cortoss ...
