  1. Spatial changes during building construction usually manifest as deviations between the as-designed model and the as-built conditions. These deviations can lead to errors that result in delays and additional costs. Project engineers often spend significant time, money, and resources to manually track and analyze changes between the as-designed mode...

  2. Deep convolutional neural networks (CNN) are useful in a variety of applications ranging from computer vision to signal processing. There is increasing interest in applying CNN to biomedical image analysis, but success is impeded by the lack of large annotated datasets in biomedical imaging. Expert annotation is tedious, time consuming and expensiv...

  3. Haptic displays have promising applications in assistive devices for the visually impaired. However, current versions of this technology remain confined to low resolution tactile replications of images, and thus provide limited usefulness. Conventional haptic displays use motors or electrodes to convert images to touch, using an interface that is a...

  4. Antibiotic resistance has become a significant public health threat. It causes billions of healthcare-related costs as well as 2 million hospitalizations and 23,000 deaths annually in the US alone. Clinical treatment of bacterial infections, especially in acute cases of sepsis, requires multiple steps, including antibiotic susceptibility testing (A...

  5. Electromagnetic Band-Gaps (EBGs) have been extensively used in low-profile antenna designs because of their in-phase reflection characteristics in certain frequency band(s). EBGs have also been used as attractive ground planes and in checkerboard surface variations. The incident waves on checkerboard patches induce current densities whose amplitud...

  6. High Impedance Surfaces (HIS) are one of the breakthroughs that emerged in the modern antenna design area in 1999. HISs are ideal candidates as antenna ground planes because of their near perfect magnetic ground conductor (PMC) behavior at particular ranges. However, current rectangular designs have a limited performance and lack efficiency in the ...

  7. The structure of proteins is a key factor that controls biomolecular interactions. Measuring the atomic scale structure of proteins, however, is very challenging. The most common method for determining protein structure is x-ray crystallography, but it suffers from difficult sample preparation, high sample demand and expense. Further, this method i...

  9. The charged-coupled device (CCD) is commonly known for its applications in digital cameras and infrared photodetectors. Although this device has been revolutionary within imaging applications, there are some shortcomings that can be improved. For instance, a conventional CCD requires a very high external voltage. High power consumption means that p...

  10. Radiography is currently the most common medical imaging procedure performed in the world, and the demand for radiography is expected to increase in the coming years. Particularly in less developed countries where there is a demand for a much more ruggedized technology, the market may skip conventional x-ray film technology in lieu of digital radio...
