Data from several projects show a significant relationship between the size of a module and its defect density. Here we address implications of this observation. Does the overall defect density of a software project vary with its module size distribution? Even more interesting is the questioncan we exploit this dependence to reduce the total number of defects? We examine the available data sets...

This paper describes a design process for custom wearable systems produced in an academic setting. A set of 245 wearable design defects from two distinct periods separated by six years in time is presented. These data identify aspects of the process requiring significant developer effort, which we show using an Orthogonal Defect Classification scheme. A comparison of defect attribute distributi...

We consider the problem of high-frequency asymptotics for the time-dependent onedimensional Schrödinger equation with rapidly oscillating initial data. This problem is commonly studied via the WKB method. An alternative method is based on the limit Wigner measure. This approach recovers geometrical optics, but, like the WKB method, it fails at caustics. To remedy this deficiency we employ the s...

In this letter we report on spectral photoconductivity (PC) on different sections of single MBE-grown GaN nanowhiskers of diameters ranging on the order of 100 nm. The photoconductivity spectra show, besides the band-gap related transition, deep-levels corresponding to the yellow, green, and blue bands. A strong spatial localization of specific photocurrent peaks has been observed, indicating t...

The confidentiality of encrypted data depends on how well the key under which it was encrypted is maintained. If a session key was exchanged encrypted under a long-term key, exposure of the longterm key may reveal the session key and hence the data encrypted with it. The problem of key-dependencies between keys can be mapped onto connectivity of a graph, and the resulting graph can be inspected...

Defects in the band gap of CuIn12xGaxSe2 have been characterized using transient photocapacitance spectroscopy. The measured spectra clearly show response from a band of defects centered around 0.8 eV from the valence band edge as well as an exponential distribution of band tail states. Despite Ga contents ranging from Ga/(In1Ga)50.0 to 0.8, the defect bandwidth and its position relative to the...

A simple 3D virtual mirror interface system is proposed for acquisition and reconstruction of facial pattern, which enables a real time tracking of 3D facial pattern. The movement of lip in the face, which can be estimated based on mean shift and Kalman filter is introduced to recognize the rotation and parallel shift of face. Modified Photometric Stereo Method (PSM) is also proposed to acquire...

Yield prediction models and critical area calculations base on defects modeled as circular disks. But, the observation of real defects provides mostly irregular defect outlines. For this reason, we investigate the influence of real defect outlines on determining defect size distributions for yield prediction. To collect data on defects, checkerboard test structures were manufactured that enable...

One of the most impressive disorders following brain damage to the ventral occipitotemporal cortex is prosopagnosia, or the inability to recognize faces. Although acquired prosopagnosia with preserved general visual and memory functions is rare, several cases have been described in the neuropsychological literature and studied at the functional and neural level over the last decades. Here we te...
