Abstract:
The new thioantimonate [Mg(en)3][Sb4S7] containing for the first time a [Mg(en)3]2+ cation as structure-directing unit was synthesized under solvothermal conditions applying elemental Mg, SbCl3, S and ethylenediamine. The compound crystallizes in the monoclinic space group P21/c with a = 9.9267(6), b = 14.254(1), c = 17.259(1) A° , β = 102.611(7)°, V = 2383.1(3) °A3, Z = 4. In the structure trigonal SbS3 pyramids are joined to form an Sb3S3 ring. The rings are connected through SbS3 units yielding an undulated chain anion running along [001]. Considering so-called secondary Sb-S bonds, a layer-like thioantimonate anion is formed. The [Mg(en)3]2+ cations are located between the layers. Relatively short S・ ・ ・H-N contacts suggest hydrogen bonding interactions between the cation and the [Sb4S7]2− anion. The compound starts to decompose at about 220 °C. The optical band gap of 2.35 eV is in agreement with the orange color of the crystals. In the Raman spectrum prominent Sb-S resonances are seen between 250 and 400 cm−1 which can be assigned to different Sb-S vibrations

Abstract:
The number of women seeking congressional office in the United States has dramatically increased since 1980. Previous research on women candidates explores why women run, but new research on candidate emergence shows that women face different challenges and advantages based on their race and ethnicity. We investigate these differences by disaggregating data on women’s candidate emergence by race and ethnicity to examine how these theories work when explicitly considering race and ethnicity. We focus our examination on women running in House primaries between 1980 and 2012. We argue that theories of candidate emergence are conditional to the racial and/or ethnic identification of the candidate. We employ a cross-sectional time series analysis with the intuition that examining congressional elections over time will allow us to make general comments about the participation of women in congressional elections. We find that many of the conditions thought necessary for women’s emergence as candidates are contextual and temporally specific. Moreover, conditions that encourage women to run do not necessarily apply to women of color.

Abstract:
Color space conversion (CSC) is an important kernel in the area of image and video processing applications including video compression. As a matrix math, this operation consumes up to 40% of processing time of a highly optimized decoder. Therefore, techniques which efficiently implement this conversion are desired. Multicore processors provide an opportunity to increase the performance of CSC by exploiting data parallelism. In this paper, we present three novel approaches for efficient implementation of color space conversion suitable for homogeneous and heterogeneous multicore. We compare the performance of color space conversion on a variety of platforms including OpenMP running on homogeneous multicore CPUs, CUDA with NVIDIA GPUs and OpenCL running on both NVIDIA and ATI GPUs. Our experimental results show that the speedup of3×, 17×and15×can been obtained, respectively.

Abstract:
In this paper, we propose a quantized YCbCr color space (QYCbCr) technique which is employed in standard JPEG. The objective of this work is to accelerate computational time of the standard JPEG image compression algorithm. This is a development of the standard JPEG which is named QYCBCr algorithm. It merges two processes i.e., YCbCr color space conversion and Q quantization in which in the standar JPEG they were performed separately. The merger forms a new single integrated process of color conversion which is employed prior to DCT process by subsequently eliminating the quantization process. The equation formula of QYCbCr color coversion is built based on the chrominance and luminance properties of the human visual system which derived from quatization matrices. Experiment results performed on images of different sizes show that the computational running time of QYCbCr algorithm gives 4 up to 8 times faster than JPEG standard, and also provides higher compression ratio and better image quality.

Abstract:
To reduce exhaust NOx and smoke, it is important to measure flame temperature and soot amount in combustion chamber. In diesel combustion it is effective to use the two-color method for the measurement of the flame temperature and KL factor, which is related with soot concentration. The diesel flame was directly and continuously observed from the combustion chamber at running engine condition by using a bore scope and a high-speed video camera. The experimental single cylinder engine has 2.0-liter displacement and has the ability with up to five times of the boost pressure than the naturally aspirated engine by external super-charger. The devices of High Boost, Wide Range and High EGR rate at keeping a relatively high excess air ratio were installed in this research engine in order to reduce exhaust NOx emission without smoke deterioration from diesel engines. The video camera nac GX-1 was used in this study. From observed data under the changing EGR rates, the flame temperature and KL factor were obtained by the software of two-color method analysis. The diesel combustion processes are understood well by analyzing high-speed movies of the diesel flame motion and its temperature. The NOx and smoke are mutually related to maximum flame temperature and also it is possible to reduce simultaneously both NOx and soot emissions by high EGR rate in a single cylinder diesel engine.

Abstract:
In order to improve the time delay estimation of colored noise signals, this article proposes generalized cross-correlation time delay estimation based on variational mode decomposition. First of all, we put forward the signal energy detection criterion to extract the effective signal from the signal, which can reduce the amount of calculation and improve the real-time performance. Second, the effective signal is decomposed into a number of intrinsic mode functions using variational mode decomposition. The correlation coefficients of each intrinsic mode function and the original signal are calculated. The article reconstructed signal with intrinsic mode functions which extract useful intrinsic mode functions by defaulting the correlation coefficient threshold. Finally, this article uses generalized cross-correlation to estimate time delay of the reconstructed signal. Theoretical analysis and simulation results show that the accurate time delay estimation can be obtained under the condition of color noise by the proposed method. The measurement accuracy of the proposed method is 15 times that of the generalized cross-correlation, and the running time of the proposed method is 4.0601 times faster than that of the generalized cross-correlation algorithm. The proposed method can reduce the computation and the running time of the system and also improve the measurement accuracy.

Abstract:
The need for simple and reliable means of respiratory monitoring has existed since the beginnings of medicine. In the present study, we describe the use of color spectrographic analysis of breathing sounds recorded from the external ear canal as a candidate technology to meet this need. A miniature electret microphone was modified with the addition of an adapter to allow it to be placed comfortably in the external ear canal. The amplified signal was then connected to a real-time color spectrogram program running on a laptop personal computer utilizing the Windows operating system. Based on the results obtained, we hypothesize that the real-time display of color spectrogram breathing patterns locally or at a central monitoring station may turn out to be a useful means of respiratory monitoring in patients at increased risk of respiratory depression or other respiratory problems. Finally, we conducted a statistical analysis that suggests that significant spectrogram differences may exist among some groups investigated in the study.

Abstract:
Headlines touted a “wave” of women and minority candidates running in the 2018 elections, leading some to conclude that 2018 was the new “year of the woman” and perhaps “year of the candidate of color” (Lai et al. 2018). In fact, the number of women and candidates of color contesting US House elections was so high in 2018 that for the first time on record, White men were the minority of Democratic House nominees (Schneider 2018). Surveys taken immediately before the 2018 midterm elections indicated that women of color were the “ideal candidates” for Democrats, suggesting a changing voter demand for a more diverse field of candidates (Easley 2018).

Abstract:
The analysis of fractal patterns has grown during the past years, mainly due to the wide range of applications to diverse scientific areas where fractals have been explored. It turns out that the key tool to study the complexity of a given system is the Fractal Dimension (FD), since this is its main invariant which throws quite useful information about the complexity that it presents when being examined with enough level of detail. In the proposed method, we adopt a hyper-surface partition method which considers the hyper-surface as continuous and divides the image into non-overlapped blocks. We present a novel counting method in the RGB color domain. The experimental results demonstrate that the proposed method shows its robustness and it can be performed as a reliable FD estimation approach for the color images. The running time of the proposed method is much shorter than that of other algorithms.

Abstract:
We describe a wayfinding system for blind and visually impaired persons that uses a camera phone to determine the user's location with respect to color markers, posted at locations of interest (such as offices), which are automatically detected by the phone. The color marker signs are specially designed to be detected in real time in cluttered environments using computer vision software running on the phone; a novel segmentation algorithm quickly locates the borders of the color marker in each image, which allows the system to calculate how far the marker is from the phone. We present a model of how the user's scanning strategy (i.e. how he/she pans the phone left and right to find color markers) affects the system's ability to detect color markers given the limitations imposed by motion blur, which is always a possibility whenever a camera is in motion. Finally, we describe experiments with our system tested by blind and visually impaired volunteers, demonstrating their ability to reliably use the system to find locations designated by color markers in a variety of indoor and outdoor environments, and elucidating which search strategies were most effective for users.
