results sore throat was recorded in 32.9% of patients with lma and 44.2% of intubated patients, but it was not statistically significant (fisher’s exact test = 0.158). hoarseness was recorded in 3.5% of patients with lma and 24.4% of intubated patients (fisher’s exact test = 0.000). in 1.2% of patients with lma cough was recorded; it was also seen in 7% of the intubated patients (fisher’s exact...

This paper describes and compares techniques for registering an image with respect to a template image when one or both are partially occluded. These techniques can be used to build correlation-based image registration (alignment of similar images) and image search (finding a sub-image within a larger image) algorithms. Binary masks as developed by Stone and Shamoon [18], and extended by Stone ...

This paper is devoted to a study of local linear independence of refinable vectors of functions. A vector of functions φ = (φ1, . . . , φr) ∈ (C(IR))r is said to be refinable if it satisfies the vector refinement equation φ(x) = ∑ α∈Z s a(α)φ(2x− α), where a is a finitely supported sequence of r×r matrices called the refinement mask. A complete characterization for the local linear independence...

We demonstrate that multilevel nanoimprint lithography ~NIL! with submicron alignment over an entire 4 in. Si wafer can be achieved. Average alignment accuracy of 1 mm with a standard deviation 0.4 mm in both X and Y directions was obtained in ten consecutive tests of multilevel NIL. The multilevel alignment was achieved by aligning the wafer and the mask with an aligner, fixing them with a hol...

Sleep apnea is a syndrome that is characterized by sudden breathing halts while sleeping. One of the common treatments involves wearing a mask that delivers continuous air flow into the nostrils so as to maintain a steady air pressure. These masks are designed for an average facial model and are often difficult to adjust due to poor fit to the actual patient. The incompatibility is characterize...

Wearing a face mask affects the speech production. On top of that, the frequency response and radiation characteristics of the face mask depending on the material and shape of the mask adds to the complexity of analyzing speech under face mask. Our target is to separate the effect of muscle constriction and increased vocal effort in speech produced under face mask from sound transmission and ra...

In this research, we have optimized a fabrication technique for manufacturing microneedle arrays in standard silicon wafer ((100) orientation) using potassium hydroxide (KOH) wet etching. The etch behaviour of silicon was simulated for different mask shapes and sizes using SIMODE software. In the context of the fabrication process, we demonstrate the influence of the mask design and the process...

Realistic face animation is especially hard as we are all experts in the perception and interpretation of face dynamics. One approach is to simulate facial anatomy. Alternatively, animation can be based on first observing the visible 3D dynamics, extracting the basic modes, and putting these together according to the required performance. This is the strategy followed by the paper, which focuse...

Simple formulae are often used to estimate the sensitivity of coded mask X-ray or gamma-ray telescopes, but these are strictly only applicable if a number of basic assumptions are met. Complications arise, for example, if a grid structure is used to support the mask elements, if the detector spatial resolution is not good enough to completely resolve all the detail in the shadow of the mask or ...
