This project leverages the Autosupport data to gain insights into the production environment as well as the QA environment in terms of their relationships to each other. Using the K-Means algorithm and direct matching method, we have identified eight common customer configuration groups, top customer configurations not tested by any QA machines, and top QA machines not testing any customer configurations.

The impact of environmental and manufacturing variability is simulated and discussed. A predictive model for manufacturing variability-induced mismatch power loss is proposed and evaluated with various PV array configurations. Finally, spatial statistics are used to model the non-uniformities of solar cell properties. A SPICE-based distributive solar cell simulator is constructed to estimate electrical performance for various defect distribution patterns. Finally, a statistical model is created in order to correlate the spatial characteristics of defect patterns with the corresponding electrical performance.

This document is our final technical report and describes the efforts under contract N00014-11-1-0521. The objective of this work was to establish the feasibility of creating solution processed metamaterials formed from composites of semiconductor quantum dots (QDs). The specific goals of this work included, (1) modeling of the metamaterial's optical properties, (2) developing fabrication techniques and (3) experimental characterization of the materials' optical properties. Modeling was first conducted and it was found that under ideal conditions, a high frequency magnetic response could be created in metamaterials formed from composites of quantum dots utilizing excitonic resonances. However, in experimentally fabricated films using cadmium selenide QDs, it was found that the excitonic resonance is significantly broadened, preventing the high index needed to realize metamaterials with tailored effective permittivity and permeability. To overcome this challenge, lead sulfide QDs were then explored due to their high bulk index. Using lead sulfide QDs it was found that a considerably higher effective constituent index could be achieved. However, it was found that thick QD films and multilayer films could not be realized without inducing severe cracking. Patterning of multilayer films was achieved but due to their thin thickness, optical resonances could not be supported.

This paper will provide an overview for the shortcomings of such attempts such as: cost, ease of integration (as well as being noninvasive), and functionality. Our system is one that implements these features by taking advantage of several new technologies, including energy harvesting techniques and innovative low-power wireless protocols and hardware.

In this paper, we first focus on four different interaction techniques to share and manipulate content on large displays by using mobile phones. We compare speed and accuracy of these techniques by gathering and analyzing data from a user study with ten participants. From the data, we find touchpad is the most appropriate interaction technique, so we choose touchpad as our primary technique for developing applications. Our approach is to execute multiple copies of several existing applications in parallel and keep them synchronized, and they can be used by multiple users through touchpad interaction. Finally, we conduct a user study with ten participants to interact with our system. The evaluation result shows that it is convenient and efficient to use our system in a collaborative environment.

In this paper, we summarize and evaluate the techniques for detecting and identifying the detection patterns in the context of clothing simulation for PR2 (and any robot using Robot Operating System as its OS). We illustrate in this context, why the marker processing algorithm introduced in ARToolkit - Based Tracking[7] is the best performer for minimal detectable pattern size and under warping configurations.

The National Research Council's (NRC) Decadal Survey (DS) of Earth Science and Applications from Space has identified the Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS) as an important atmospheric science mission. NASA Langley Research Center, working with its partners, is developing fiber laser architecture based intensity modulated CW laser absorption spectrometer for measuring XCO2 in the 1571 nm spectral band. In support of this measurement, remote sensing of O2 in the 1260 nm spectral band for surface pressure measurements is also being developed. In this paper, we will present recent progress made in the development of advanced transmitter modules for CO2 and O2 sensing. Advanced DFB seed laser modules incorporating low-noise variable laser bias current supply and low-noise variable temperature control circuit have been developed. The 1571 nm modules operate at 80 mW and could be tuned continuously over the wavelength range of 1569-1574nm at a rate of 2 pm/mV. Fine tuning was demonstrated by adjusting the laser drive at a rate of 0.7 pm/mV. Heterodyne linewidth measurements have been performed showing linewidth (approximately)200 kHz and frequency jitter (approximately)75 MHz. In the case of 1260 nm DFB laser modules, we have shown continuous tuning over a range of 1261.4 - 1262.6 nm by changing chip operating temperature and 1261.0 - 1262.0 nm by changing the laser diode drive level. In addition, we have created a new laser package configuration which has been shown to improve the TEC coefficient of performance by a factor of 5 and improved the overall efficiency of the laser module by a factor of 2.

State-of-the-art multijunction cell designs have the potential for significant improvement before going to higher number of junctions. For example, the Voc can be substantially increased if the photon recycling taking place in the junctions is enhanced. This has already been demonstrated (by Alta Devices) for a GaAs single-junction cell. For this, the loss of re-emitted photons by absorption in the underlying layers or substrate must be minimized. Selective back surface reflectors are needed for this purpose. In this work, different architectures of semiconductor distributed Bragg reflectors (DBR) are assessed as the appropriate choice for application in monolithic multijunction solar cells. Since the photon re-emission in the photon recycling process is spatially isotropic, the effect of the incident angle on the reflectance spectrum is of central importance. In addition, the DBR structure must be designed taking into account its integration into the monolithic multijunction solar cells, concerning series resistance, growth economics, and other issues. We analyze the tradeoffs in DBR design complexity with all these requirements to determine if such a reflector is suitable to improve multijunction solar cells.
