Image segmentation is a predefined process of image processing to determine a specific object. One of the problems in food recognition and food estimation is the lack of quality of the result of image segmentation. This paper presents a comparative study of different color space and color channel selection in image segmentation of food images. Based on previous research regarding image segmentation used in food leftover estimation, this paper proposed a different approach to selecting color space and color channel based on the score of Intersection Over Union (IOU) and Dice from the whole dataset. The color transformation is required, and five color spaces were used: CIELAB, HSV, YUV, YCbCr, and HLS. The result shows that A in LAB and H in HLS are better to produce segmentation than other color channels, with the Dice score of both is 5 (the highest score). It concludes that this color channel selection is applicable to be embedded in the Automatic Food Leftover Estimation (AFLE) algorithm.

This article describes an experimental investigation in the near field of five parallel plane jets. The study applies 2D Particle Image Velocimetry (PIV) for ventilated and unventilated jets, where ventilated means exiting into a duct with expansion ratio 3.5 and unventilated means exiting to the free atmosphere. Results are presented for Reynolds numbers 1408, 5857 and 10510. The Reynolds number is calculated for the middle channel and is based on the height of the nozzle (channel) equivalent diameter 2h. All characteristic regions of the methodology to describe multiple interacting jets are observed by the PIV measurements - converging, merging and combined. Each of the five parallel channels has an aspect ratio of 25 defined as nozzle width (w) to height (h). The channels have a length of 185 times the channel height guaranteeing a fully developed velocity profile at the exit from the channel. Spacing between the single plane jets is 3 times the channel height. The near field of multiple mixing jets is depended on outlet nozzle geometry. Blunt geometry of the nozzle was chosen (sudden contraction).

Quantum circuits to realize color operations of channel of interest, channel swapping, and alpha blending on images are proposed using five kinds of quantum gates, i.e., NOT, CNOT, Toffoli, Rotation, and Controlled Rotation gates. Complexities of the proposed circuits are for an N-sized image, whereas the color information must be transformed pixel by pixel in the case of operators on classical computers. Simulations on the proposed three quantum color operations using three human facial and one Japanese style house images demonstrate that at most 9, 3, and 5 basic quantum gates are requested, that shows the feasibility of quantum circuits. Based on proposed three operations, all invertible classical color information transformation on imagesmay be designed and many applications can be realized on quantum computer, and the channel of interest based watermarking is being researched which the experiment results show that from the point of PSNR, our proposal is about 10 dB better than the chosen method of quantum image watermarking.

Abstract. The inhomogeneous sky background presents a great challenge for accurate cloud recognition from the total-sky images. A channel operation was introduced in this study to produce a new composite channel in which the difference of atmospheric scattering has been removed and a homogeneous sky background can be obtained. Following this, a new cloud detection algorithm was proposed that combined the merits of the differencing and threshold methods, named differencing and threshold combination algorithm (DTCA). Firstly, the channel operation was applied to transform 3-D RGB image to the new channel, then the circumsolar saturated pixels and its circularity were used to judge whether the sun is visible or not in the image. When the sun is obscured, a single threshold can be used to identify cloud pixels. If the sun is visible in the image, the true clear-sky background differencing algorithm is adopted to detect clouds. The qualitative assessment for eight different total-sky images shows the DTCA algorithm obtained satisfactory cloud identification effectiveness for thin clouds and in the circumsolar and near-horizon regions. Quantitative evaluation also shows that the DTCA algorithm achieved the highest cloud recognition precision for five different types of clouds and performed well under both visible sun and blocked sun conditions.

<p class="0abstract">To solve the fusion problem of visible and infrared images, based on image fusion algorithm such as region fusion, wavelet transform, spatial frequency, Laplasse Pyramid and principal component analysis, the quality evaluation index of image fusion was defined. Then, curve-let transform was used to replace the wavelet change to express the superiority of the curve. It integrated the intensity channel and the infrared image, and then transformed it to the original space to get the fused color image. Finally, two groups of images at different time intervals were used to carry out experiments, and the images obtained after fusion were compared with the images obtained by the first five algorithms, and the quality was evaluated. The experiment showed that the image fusion algorithm based on curve-let transform had good performance, and it can well integrate the information of visible and infrared images. It is concluded that the image fusion algorithm based on curve-let change is a feasible multi-sensor image fusion algorithm based on multi-resolution analysis. </p>

Abstract With the advent of digital elevation models (DEMs) and geographic information systems (GIS), several methods have been proposed to extract channels from raster DEMs. Light detection and ranging (lidar) can produce high-resolution DEMs and poses new challenges to existing methods for channel extraction. This paper introduces a semi-automated method for extracting stream channels and channel profiles from high-resolution DEMs using image processing techniques. Based on user-specified approximate locations of start and end points and a few simple parameters, the method implements five automated steps: (1) channel detection using a local minimum value search; (2) channel delineation using Bresenham’s line algorithm and mathematical morphological operation; (3) vectorization; (4) profile generation; and (5) accuracy assessment. The method is implemented as an ArcGIS Python add-in toolbar named Channel Extraction. The application of the toolbar is demonstrated using a lidar-derived DEM in a study area along the San Andreas fault in California, USA. The software and test data are freely available for download (see Supplemental Files1). The demonstrated samples suggest that this new semi-automated method for extracting channels and channel profiles is flexible and user-friendly and can produce accurate results to support geomorphic studies.

The optic disc (OD) in retinal fundus images is widely used as a reference in computer-based systems for the measurement of the severity of retinal disease. A number of algorithms have been published in the past 5 years to locate and measure the OD in digital fundus images. Our proposed algorithm, automatically: (i) uses the three channels (RGB) of the digital colour image to locate the region of interest (ROI) where the OD lies, (ii) measures the Shannon information content per channel in the ROI, to decide which channel is most appropriate for searching for the OD centre using the circular Hough transform. A series of evaluations were undertaken to test our hypothesis that using the three channels gives a better performance than a single channel. Three different databases were used for evaluation purposes with a total of 2,371 colour images giving a misdetection error of 3% in the localisation of the centre of the OD. We find that the area determined by our algorithm which assumes that the OD is circular, is similar to that found by other algorithms that detected the shape of the OD. Five metrics were measured for comparison with other recent studies. Combining the two databases where expert delineation of the OD is available (1,240 images), the average results for our multispectral algorithm are: TPR = 0.879, FPR = 0.003, Accuracy = 0.994, Overlap = 80.6% and Dice index = 0.878.

Abstract. Obtaining an accurate cloud-cover state is a challenging task. In the past, traditional two-dimensional red-to-blue band methods have been widely used for cloud detection in total-sky images. By analyzing the imaging principle of cameras, the green channel has been selected to replace the 2-D red-to-blue band for detecting cloud pixels from partly cloudy total-sky images in this study. The brightness distribution in a total-sky image is usually nonuniform, because of forward scattering and Mie scattering of aerosols, which results in increased detection errors in the circumsolar and near-horizon regions. This paper proposes an automatic cloud detection algorithm, "green channel background subtraction adaptive threshold" (GBSAT), which incorporates channel selection, background simulation, computation of solar mask and cloud mask, subtraction, an adaptive threshold, and binarization. Five experimental cases show that the GBSAT algorithm produces more accurate retrieval results for all these test total-sky images.

The goal of no-reference image quality assessment (NR-IQA) is to predict the quality of an image as perceived by human observers without using any pristine, reference images. In this study, an NR-IQA algorithm is proposed which is driven by a novel feature vector containing statistical and perceptual features. Different from other methods, normalized local fractal dimension distribution and normalized first digit distributions in the wavelet and spatial domains are incorporated into the statistical features. Moreover, powerful perceptual features, such as colorfulness, dark channel feature, entropy, and mean of phase congruency image, are also incorporated to the proposed model. Experimental results on five large publicly available databases (KADID-10k, ESPL-LIVE HDR, CSIQ, TID2013, and TID2008) show that the proposed method is able to outperform other state-of-the-art methods.

Purpose This project aims to explore the classification method of kinase inhibitors with five-channel cell painting image data based on the deep learning model. Methods A ResNet50 transfer learning model was used as the starting point to build the deep neural network (DNN) model, where different DNN parameters were selected to make the deep learning model more suitable for the cell painting data. Two different adaptive layers (adaptive average pooling 3D and convolution 2D) were added separately before the ResNet50 transfer learning model to adapt the five-layer cell painting image to the neural network. In addition, the skimage.transform.resize function was used to compress the five-layer cell painting image. Results The proposed deep learning model demonstrates the effectiveness in all three classification experiments. The proposed model performs particularly well in classifying among control, EGFR, PIKK and CDK kinase inhibitors families. It achieves an F1-score of 0.7764 on all four targets and has a 93\% accuracy rate in the PIKK kinase inhibitors family. The adaptive average pooling 3D layer successfully adapts the five-layer images to the model, resulting in an improved effect. The training time of the model is significantly reduced to one-fortieth by compressing the image size. Conclusion The proposed model achieved convincing effectiveness in classifying families, which showed progress in building the deep learning model to classify kinase inhibitors on five-channel cell painting data. This study also proved the feasibility of directly inputting five-channel cell painting images to DNN. In addition, the speed of the model increased sharply by compressing the image size without an obvious loss of data information.

Barrier islands are dynamic environments facing increasing vulnerability to climate changes, sea level rises, and anthropogenic activities. Hurricane Sandy (October 2012) modified the Atlantic coast of the United States. On Fire Island and Westhampton Island, New York, multiple overwashes and three breaches occurred. The U.S. Army Corps of Engineers filled two breaches, increased dune elevation and stabilized dunes by planting American beachgrass (Ammophila breviligulata). They built two restoration areas to mitigate the impact of an island stabilization project to federally listed breeding piping plovers (Charadrius melodus). The goal of this thesis was to quantify habitat changes after Hurricane Sandy, and assess habitat use of piping plovers specifically in human-created restoration areas. We created land cover maps using an object-based classification method (overall accuracy 85%), and field-collected data from four post-hurricane habitat types. Vegetation cover increased across all habitat types, especially in manipulated (30.1% increase) and natural overwashes (37.9% increase), while dry sand for nesting declined by 8%. Vegetation density indices were higher in natural overwashes than planted engineered dunes, likely a reflection of plant age and establishment. We monitored 83 nests (67 pairs) of piping plovers from 2015�"2017. Restoration areas were successful in attracting breeding piping plovers, although pair densities were lowest in this habitat in 2016, and in 2017 plovers selected against the restoration areas (�2 = 29.47, df = 3, p<0.0001). There was no effect of habitat type on reproductive parameters. We suggest vegetation removal may be necessary to maintain early successional habitats for piping plover management.Master of Science
Barrier islands are thin strips of land, which generally lie parallel to the mainland. They are dynamic environments subject to change from weather conditions and ocean currents. They are vulnerable to future climate changes, sea level rise, and increased human activity. Hurricane Sandy, October 2012, caused major landscape changes to the Atlantic coast. On two barrier islands, Fire Island and Westhampton Island, south of Long Island, the U.S. Army Corps of Engineers (USACE) further modified the post-hurricane habitats. They created two restoration sites designed to offset the impact of an island stabilization project to a federally protected breeding shorebird, the piping plover. Piping plovers nest on unvegetated or sparsely vegetated sand. We created land cover maps from aerial images and collected field data to describe habitat changes after Hurricane Sandy (2013, 2015–2017) in four habitat types creating during or after the hurricane. The vegetation cover and density increased across these four habitats, but especially in the manipulated overwashes and natural overwashes. This is likely due to the age of the plants in each habitat type. As vegetation grew back, areas of sand in each habitat type declined. Human-created restoration sites were used by plovers but in 2017 plovers used them less than expected. We monitored piping plover nests and chicks (April to August 2015–2017), and there were no differences in these measurements among habitat types. The findings from this thesis will assist in piping plover conservation on Fire Island and Westhampton Island.

Magister Scientiae (Biodiversity and Conservation Biology) - MSc (Biodiv and Cons Biol)Areas of high biodiversity and complex species assemblages are often difficult to manage and to set up meaningful monitoring and evaluations programmes. Mountain Fynbos is such an ecosystem and in the Cape of Good Hope (part of the Table Mountain National Park) plant biodiversity over the last five decades has been in decline. The reasons are difficult to speculate since large herbivores, altered fire regimes and even climate change could be contributors to this decline which has been quantified using fixed quadrats and standard cover-abundance estimates based on a Braun-Blanquet methodology. To provide more detailed data that has more resolution in terms of identifying ecological processes, Fixed-Point Repeat Photography has been presented as a management “solution”. However, photography remains a difficult method to standardize subjects and has certain operational limitations.

This thesis presents evidence of an extended period of research which has both a practical and a written outcome. Being primarily practice-based research, its principal outcome is the production and exhibition of three new video installations featuring the use of digital imaging techniques in their production, combined with the utilisation of sculptural display structures in their presentation and exhibition. The three works under consideration are Mind's Eye (exhibited July-Aug. 1997); Mothlight (exhibited April 1998, April 1999 and May 1999); and Merging/Emerging (exhibited June-July 1999). The thesis contains an extended discussion of the concepts and concerns behind these works, as well as an analysis of the interrelationships between them and my previous video installation work produced in the period between 1990 and 1995. (The appendix to this thesis contains the original proposals for these three new works, as well as a CD Rom with documentation of the exhibited works.) The other main component of this research is an exploration and discussion of the influence of significant changes in video imaging techniques on the development of video art in the United States and the United Kingdom. in the period between 1960 and 1990. This evolving relationship between video technology and video art is explored predominantly through an examination of art works and statements made by particular video artists who's work is relevant to my concerns, but also includes observations and statements by critics, writers and curators who are concerned with the development of the medium within a fine art context. Section One examines and discusses the historical and cultural context, tracing the evolution of video as an art form in relation to significant developments in the technology, including its origins, discussing in some detail the emergence of the genre in its early formative period, with particular attention to the contributions of individual artists. There is a significant section which discusses the work of artists who have experimented with and built special video imaging tools in both the US and the UK. Section Two examines specific works by artists operating in the United States and the United Kingdom under four main headings, acknowledging the impact of the most significant technological developments identified in the first section. Specific video art works are discussed under the following categories: 'Non-broadcast' video, frame- accurate editing, electronic image manipulation techniques and video display equipment for installation. section Three traces the development of my own fine art practice in video during the period between 1978 and 1995, examining the influence of video technology on the work and discussing issues related to the accessibility of image production facilities, as well as the impact of this technology on the development of formal innovation and its interrelationship to content. This section also discusses and examines the influence of artists working in related areas such as experimental film and music, with a special emphasis on the influence of the avant-garde film movement of the 1970's. This section is to a certain extent cross-referenced with the previous section, as many of the artists and works cited were important to the evolution of my own fine art practice. The final section examines in detail the ideas, concepts and development of the three new video installations that form the core of this research: Mind's Eye (1997), Mothlight (1998-99) and MerginglEmerging (1999). Each installation is described in detail and discussed in relation to its ideas and themes, as well as with reference to the technical processes employed and the formal concerns of the work. This section also includes a discussion of issues in relation to notions of site-specificity.

Most accounts of Hinduism posit a radical difference between the aniconic fire sacrifice (yajña) and temple-based image worship (pūjā). The historical distinction between ancient Vedism and medieval Hinduism is often premised on this basic ritual opposition. Through an exacting study of ritual manuals, Rites of the God-King offers an alternative account of the formation of mainstream Hindu ritual through the history of śānti, or “appeasement,” a form of aspersion or bathing, developed in order to counteract inauspicious omens. This ritual, which originated at the nexus of the fourth and somewhat marginal Veda (Atharvaveda) and the emergent tradition of astronomy-astrology (Jyotiḥśāstra), would come to have far-reaching consequences on the ideal ritual life of the king in early medieval Brahmanical society—and on the ideal ritual life of images. The mantric substitutions involved in this history helped to produce a politicized ritual culture that could encompass both traditional Vedic and newer Hindu practices and performers. From astrological appeasement to gifting, coronation, and image worship, the author chronicles the multiple lives and afterlives of a single ritual mode, disclosing the always inventive work of priesthood to imagine and enrich royal power. Along the way, he reveals the surprising role of astrologers in Hindu history, elaborates concepts of sin and misfortune, and forges new connections between medieval texts and modern practice. Detailing forms of ritual that were dispersed widely across Asia, he concludes with a reflection on the nature of orthopraxy, ritual change, and the problem of presence in the Hindu tradition.

This article appears in theOxford Handbook of New Audiovisual Aestheticsedited by John Richardson, Claudia Gorbman, and Carol Vernallis. This chapter asks what music video has become today and how its audiovisual aesthetics have changed online. It suggests that music videos generally through process of remediation content more actively than any other media form, performing the dual function of “visualizing music” (by recasting a song visually) and “musicalizing vision” (by structuring images according to musical logic). The discussion identifies and provides an overview of several new music video types that have come into existence online, placing them in five categories. In particular, the chapter focuses on interactive music videos and music video apps through close analyses of both Arcade Fire’s interactive video “We Used to Wait” and Björk’s interactive “app album”Biophilia. Both of these actively challenge what we have come to expect of music videos while still performing some familiar functions, prompting us to consider whether they are even music videos.

A book about the samurai from their origins in the eighth and ninth centuries until their demise in the mid-nineteenth century. It describes samurai life, work, philosophy, and warfare as it changed over time and covers what samurai were doing when they weren’t fighting. The first half of the book tends to focus on warriors who were essentially aristocrats; warrior families who looked to non-warrior nobles for models of behaviour, lifestyle, and politics. It traces the early formation of a warrior regime, how it interacted with an emperor-centered noble court located permanently in Kyoto, and the political and cultural struggles within the warrior class. The second half of the book zeroes in on the details of warlord families, the struggles of “rank-and-file” samurai typically depicted in popular culture—warriors from the seventeenth through nineteenth centuries. It also shows how samurai history, culture, and values were consumed by non-samurai and, in so doing, contributed to an idealized warrior image that even samurai themselves tried to emulate.

Along with the rapid expansion of the market economy and industrial production methods, innovations including photography, lithography, and steam printing created a pictorial revolution in the nineteenth century. Consuming Identities: Visual Culture in Nineteenth-Century San Francisco explores the significance of that revolution in one of its vanguard cities: San Francisco, the revolving door of the gold rush and the hub of Pacific migration and trade. The proliferation of visual prints, ephemera, spectacles, and technologies transformed public values and perceptions, and its legacy was as significant as the print revolution that preceded it. In their correspondence, diaries, portraits, and reminiscences, thousands of migrants to the city by the Bay demonstrated that visual media constituted a central means by which to navigate the bewildering host of changes taking hold around them in the second half of the nineteenth century. Images themselves were inextricably associated with these world-changing forces; they were commodities, but they also possessed special cultural qualities that gave them new meaning and significance. Visual media transcended traditional boundaries of language and culture that had divided groups within the same urban space. From the 1848 conquest of California and the gold discovery to the disastrous earthquake and fire of 1906, San Francisco anticipated broader national transformations in the commodification, implementation, and popularity of images. For the city’s inhabitants and visitors, an array of imagery came to mediate, intersect with, and even constitute social interaction in a world where virtual reality was becoming normative.

The Motion Picture Production Code controlled the content and final cut on all films made and distributed in the US from 1934 to 1968. Code officials protected sensitive ears from the standard four-letter words as well as a few five-letter words like tramp and six-letter words like cripes. They also scrubbed ‘excessively lustful’ kissing from the screen, and ensured that no criminal went unpunished. Censors demanded an average of twenty changes, ranging from trivial to mind-boggling, on each of Alfred Hitchcock’s films during his most productive years. No production escaped these changes, which rarely improved the finished film. Code reviewers dictated the ending of’ Rebecca, shortened the shower scene in’ Psycho, absolved Cary Grant of guilt in’ Suspicion, edited Cole Porter’s lyrics in’ Stage Fright, and decided which shades should be drawn in’ Rear Window. Nevertheless, Hitchcock still managed to push the boundaries of sex and violence permitted in films by charming (and occasionally tricking) the censors and by swapping off bits of dialogue, plot points, and individual shots (some of which had been deliberately inserted as trading chips) to protect cherished scenes and images. The director’s priorities in dealing with the censors highlight both his theories of suspense and the single-mindedness of Code officials. Hitchcock and the Censors’ traces the forces that led to the Production Code and describes Hitchcock’s interactions with Code officials on a film-by-film basis as he fought to protect his creations, bargaining with Code reviewers and sidestepping censorship to produce a lifetime of memorable films.

How does science, in the period from the end of the eighteenth to the middle of the twentieth century, come to have such a central place in Western culture? At issue in the consolidation of a scientific culture is the way in which all cognitive values, and subsequently many moral, political, and social ones, come to be modelled around scientific values, and Civilization and the Culture of Science explores how these values were shaped and how they began in turn to shape those of society. The book continues the trajectory of three earlier volumes, which traced key aspects of the legitimation of science and the establishment of a scientific culture up to the early decades of the nineteenth century. The core nineteenth- and twentieth-century development is that in which science comes to take centre stage in shaping ideas of civilization. A central question is the role played by projects to unify the sciences, showing how the motivation for these comes from outside. A crucial part of this process was a fundamental rethinking of the relations between science and ethics, economics, philosophy, and engineering. The developments here are not linear or one-dimensional, and five issues that have underpinned the transition to a scientific modernity are explored: changes in the understanding of civilization; the push to unify the sciences; the rise of the idea of the limits of scientific understanding; the ideas of ‘applied’ and ‘popular’ science; and the way in which the public was shaped in a scientific image.

Modern digital echo laboratories are based on echo scanners working in a network with file server(s) and work-station computers for offline analysis and reporting. They may be based on vendor-specific software, but are preferably based on vendor-independent software solutions, being able to handle data from all brands of scanners. To enable analysis of advanced echocardiographic techniques, plug-ins for vendor-specific solutions should be integrated in the otherwise vendor-independent software. To obtain full efficiency, the system should be integrated with the hospital information system for patient demographics and scheduling, and the approved report should automatically be returned to the electronic patient record without the need for scanning or other handling by manpower. To obtain this, a variety of standards have been developed, most of them for medical imaging in general. Scanners of all major brands deliver data compatible with those standards, even if compatibility problems may occur. When the optimal solution for the individual organization has been established, running the echo lab changes significantly. Digital images are stored on safe repositories without quality loss and are available for viewing outside the echo lab. Offline measurements, structured reporting, education, research, quality control, and financial analyses are available. The lab becomes more efficient and cost-effective.

Abstract DATA of Aerosol Robotic Network (Aeronet) stations and Ozone Monitoring Instrument (OMI) were obtained to get valuable and reliable information about the occurrence of dust events. In addition to Total Ozone Mapping Spectrometer (TOMS) provide informative and long dust events record. To analyze the dust time series, monthly, annual and seasonal linear trends are applied to the dust time series. This is achieved by summing the total number of dusty hours for each month and then the total number of dusty days for the month is calculated. Dust trend analysis includes; annual, winter, spring, summer and autumn with the rate of change. Dust frequency of seasons in days/season before and after sorting in a descending manner from 1984 to 2013.

This chapter summarizes the main arguments of the book and discusses how each of the five shocks shaped the outcomes of the 2015 and 2017 general elections. We reflect on the role played by the three different mechanisms identified in our theory—salience, competence, and party image—which had varying degrees of importance in the impact of each shock. We consider whether the changes might be long-lasting and how new identities may (or may not) replace fading party identities, and the implications our book has for the future of British politics, and for a more general understanding of electoral change.

The chapter explores the difficult period between Solidarity Day and the 1984 presidential election. Facing a hostile political climate and an ongoing economic recession, the AFL-CIO tried to continue fighting back. In 1982, 1983, and 1984, Kirkland organized Solidarity Day II, III, and IV, and all were large marches. There were some significant internal reforms, as Kirkland oversaw the continued diversification of the Executive Council. Other changes strove to improve the AFL-CIO’s image in the media and to increase communication with members. Kirkland also launched a major organizing campaign in Houston, a brave effort in hostile territory. Continuing to see itself as a “People’s Lobby,” the Federation had some success in defending important social programs, particularly Social Security. Overall, however, Kirkland’s reforms did not go far enough, and union density declined at a rapid rate in these years. President Reagan also won re-election easily in 1984, placing the AFL-CIO and its members further under fire.

The period between 1928 and 1941 witnessed two marked trends: the growing sympathy for China’s anti-Japanese cause in the English-language press and the development of China’s foreign propaganda system. The two processes were closely connected. Even before China became a military ally of the United States and Britain after Pearl Harbor, it had already become an emotional ally. A change in national image is always a complex process. Other elements, such as the conflict of interests between the Western powers and Japan as well as Japanese atrocities in China, may well have contributed to the shift in public opinion. Yet it is undeniable that China’s continuous propaganda efforts intensified the existing tensions between Japan and the Western powers and strongly promoted the change. History does not allow “what if” questions. Yet some hypothetical scenarios are useful in urging us toward a reevaluation of the significance of certain stories and events that are absent from current history telling. Would the United States have entered the war in 1941 without any propaganda effort from the Nationalist government? Had the United States delayed confrontation with Japan and stayed out of East Asia, could Chiang Kai-shek’s government have survived Japan’s encirclement? If the Chiang Kai-shek regime had collapsed in the early 1940s, would World War II have ended with the same result?...

The goal of this chapter is to describe a Computer-Aided Therapeutic Response Assessment (CADrx) system for early prediction of drug treatment response for Glioblastoma Multiforme (GBM) brain tumors with Diffusion Weighted (DW) MR images. In conventional Macdonald assessment, tumor response is assessed nine weeks or more post-treatment. However, this chapter will investigate the ability of DW-MRI to assess response earlier, at five weeks post treatment. The Apparent Diffusion Coefficient (ADC) map, calculated from DW images, has been shown to reveal changes in the tumor’s microenvironment preceding morphologic tumor changes. ADC values in treated brain tumors could theoretically both increase due to the cell kill (and thus reduce cell density) and decrease due to inhibition of edema. In this chapter, the authors investigate the effectiveness of features that quantify changes from pre- and post-treatment tumor ADC histograms to detect treatment response. There are three parts in this technique: First, tumor regions were segmented on T1w contrast enhanced images by Otsu’s thresholding method and mapped from T1w images onto ADC images by a 3D Region of Interest (ROI) mapping tool. Second, ADC histograms of the tumor region were extracted from both pre- and five weeks post-treatment scans and fitted by a two-component Gaussian Mixture Models (GMM). The GMM features as well as standard histogram-based features were extracted. Finally, supervised machine learning techniques were applied for classification of responders or non-responders. The approach was evaluated with a dataset of 85 patients with GBM under chemotherapy, in which 39 responded and 46 did not, based on tumor volume reduction. The authors compared adaBoost, random forest, and support vector machine classification algorithms, using ten-fold cross validation, resulting in the best accuracy of 69.41% and the corresponding area under the curve (Az) of 0.70.

The 2000 campaigns focused on experimentation with DCTs. Changes in election laws made collecting contributions online feasible, which became a focus of campaigns. John McCain was savvy at capitalizing on fundraising, establishing the infrastructure to channel enthusiasm into money following key events. George W. Bush built a massive voter file for microtargeting. Steve Forbes constructed an image as the first “Internet candidate,” while Al Gore, who also should have done so, instead used DCTs conservatively. Bill Bradley developed a community involvement kit, a clear indication that campaigns began to see the potential of two-step flow. Yet, campaigns were still generally distrustful of what might happen if they let their supporters genuinely engage with the campaign. As hierarchical organizations with professional and highly paid senior staff who at their gut level—and through their experience know how to campaign—the idea of more citizen-driven efforts in political campaigns was unthinkable.

The positive effects of the festivals are composed of five factors: social image and entertainment opportunities, infrastructure and urban development, local promotion, economic development, and socio-cultural changes. The negative effects of the festival consisted of four factors: traffic problems, environmental risks and social conflict, security risks, and economic costs. As a result of the testing of research hypotheses, it has been determined that two factors (social image and entertainment opportunity, economic development) which are among the positive effects of the festival have a positive effect on the support of the local people to the development of tourism. Among the negative effects of the festival, environmental risk and social conflicts and traffic problems factors have been found to have a negative effect on the support of the local people to the development of tourism.

This chapter examines the motives, characteristics, and marketing impacts of celebrity fans in China, and illustrates these points using the fans of Wallace Chung. Based on a grounded theoretical approach, the analysis reveals five fan segments with different motives and marketing impacts: casual fans (playful, limited marketing impacts); fascinated fans (aspirational, fervent purchasers); devoted fans (sense of belonging, voluntary marketer-promoters and fervent purchasers); dysfunctional fans (identification with celebrity, rally pro); and reflective fans (solid self-identity, celebrity image-shapers). The analysis shows that in addition to buying celebrity-related products, fans undertake essential marketing activities (celebrity image-shapers, voluntary marketer-promoter) that in the past were the domains of agency management and marketers of endorsed products. These changes elevate fans to become marketing partners. Implications are discussed.

The advent of globalization has brought about innumerable changes in the Indian society. Advertisements reflect the changing society. In the said context, the authors have studied the print advertisements related to male grooming products in India over a twenty-five-year period by using the Multimodal Discourse Analysis and the framework of Roland Barthes semiotics study. The current study encompassed two prime purposes – the first being that of identifying and understanding the important codes of visual image in the male grooming sector; and the second being to discern the changes (if any) hitherto in the Indian culture. The findings from the present study reinforced the view that advertisements do mirror the changes in the society and hence the emergence of the Indian metrosexual men.

Catherine of Siena thought that fire was the best image for describing God’s nature, as well as the longing within her for union with God’s fiery love. Fire, says Bachelard, is both a domestic element (symbolic of warmth, love, and the hearth) and an unruly element (wild, threatening, attacking from without). In alchemy, fire is that catalyst for change. In religious symbolism, it signifies the transformative power of the divine and the flaming passion of human desire. Both can be as dangerous as they are life-changing. The author explores this nature archetype as he backpacks through a recently burned forest in Wyoming. He points the reader to Catherine’s “fire of holy desire” continually burning within her. Fire was her favorite element—full of life, intensity, brilliance, death, and danger. She knew God above everything else to be a fire of love. This is what set her aflame. “If you are what you should be,” she wrote to a friend, “you will set the world on fire.”

Micro-resolution Particle Image Velocimetry (Micro-PIV) was used to measure the flow in a micro-branch (Micro-Bypass). In this paper, effects of particle lump at the tip of a Micro-branch and difficulties of Micro-PIV measurements for microfluidics with branch passage were described. Micro-bypass was composed of a straight channel (200μm width×80μm height) and two branches which has 100μm width×80μm height. One of branches was straight and the other was curved. Experiments were performed at three regions along streamwise direction (enterance, middle and exit of branch) and five planes along vertical direction (0,± 10,±20μm) for the range of Re = 0.24, 1.2, 2.4. Numerical simulation was done to compare with the measurements and understand the effects of particle lump at the tip of branch.

Abstract Particle Image Velocimetry has become a desirable tool to investigate turbulent flow fields in different engineering applications, including flames, combustion engines, and turbomachinery. The convergence characteristics of turbulent statistics of these flow fields are of prime importance since they help with the number of images (temporally uncorrelated) to be captured in order for the results to converge to a certain tolerance or with the assessment of the uncertainty of the measurements for a given number of images. The present work employs Stereoscopic Particle Image Velocimetry to examine the turbulent flow field at the inlet of an automotive turbocharger compressor without any recirculating channel. Optical measurements were conducted at five different mass flow rates spanning from choke to surge at a corrected rotational speed of 80 krpm. The velocity fields thus obtained were used to analyze the convergence of the mean (first statistical moment) and variance (second statistical moment) at different operating conditions. The convergence of the mean at a particular location in the flow field depends on the local coefficient of variation (COV). The number of required images for the mean to converge to a particular tolerance was also found to follow roughly a linear trend with respect to COV. While the convergence of the variance, on the other hand, did not appear to show any direct dependence on the coefficient of variation, it takes significantly more images than the mean to converge to the same level of tolerance.

The characteristics of fluid flow and heat transfer within a smooth three-pass channel of a real low pressure (LP) turbine blade have been investigated through experimental and numerical approaches. The serpentine channel consists of two inlet passes, two dividing walls, two 180 degree bends, twenty-five exits at the trailing edge, and two exits at the blade tip. In the experiments, purified water was used as working medium, the secondary flow patterns at five cross-sections were captured by a particle image velocimetry (PIV) system, the inlet Reynolds number was controlled by a turbine flow meter, and the mass flow rate ejected from each exit was measured by rotameters. Using the commercial software ANSYS CFX 13.0, numerical investigations were carried out. The practicability of four turbulence models, the SSG RSM, SST k-ω, RNG k-ε and standard k-ε models, were estimated. Through qualitative and quantitative comparisons of the secondary flow patterns, local velocity variation trends and mass flow rates between the experimental data and numerical results, the SSG RSM was selected as the most appropriate model in the following numerical investigations. Using ideal gas as working medium, the impacts of Reynolds numbers and rotation numbers on the heat transfer performances were numerically investigated. The numerical results predicted three interesting phenomena: 1) The locally averaged Nusselt number increases generally with the inlet Reynolds numbers. However, the increasing amplitude is significantly different from the correlation suggested by Dittus-Boelter, Nuo = 0.023Re0.8Pr0.4. The effect of the Reynolds number on the Nusselt number is substantially enhanced due to the serpentine channel design with two 180 degree-bends. The enhancement amplitude is described by two fitted coefficients based on Dittus-Boelter correlation. 2) Under a rotation condition, in the 1st and 3rd passes, the enhancement amplitude of the average Nusselt number on the pressure side (PS) is more significant than that on the suction side (SS), whereas in the 2nd pass, the enhancement amplitude on the PS is lower than that on the SS. 3) In the 3rd pass, a higher rotation number leads to a more uniform distribution of the local Nusselt number along the streamwise direction on both the PS and SS.

This paper presents an experimental investigation on the flow characteristics within an entire coolant channel of a 2nd stage high pressure (HP) static turbine blade using TRPIV (Time-Resolution Particle Image Velocimetry) technique. The serpentine channel with three passages connected by a sharp bend, a round bend, 2 tip exits, 8 tailing exits and 40 film-holes staggered arranged on pressure side (PS) of the third pass is chosen as specimen, whose cross sections are manufactured to keep the real blade-shape. Ribs with a fixed spacing-to-height of 7 and an angle of 60° to the flow direction are applied on two opposite walls. The experiment is carried out at a fixed inlet Reynolds number of Rein = 23508. The variation process of secondary vortices and the main flow patterns in typical planes of the realistic coolant channel are successfully captured by TRPIV technique. The effects of rib, bend, cross-sectional shape, layout of passages, ejection ratio on the flow characteristics are analyzed and discussed. The following five new phenomena can be obtained. Namely, 1) near the two bend-regions, the rib can reduce the size of separation bubble and generate a new flow-acceleration downstream of the rib. 2) The rib-vortices combined with the mixing vortex caused by the bend and layout of channels, which leads to a new pair of vortices downstream of the bend, and further downstream, in the pair of vortices, the larger vortex presses the smaller vortex to form a new large vortex. This phenomenon has not been captured up to now in simplified ribbed two-pass channels and smooth realistic channels. 3)The development process of the secondary vortices and asymmetric behavior of main flow structure are similar in the regions of the sharp and round bends. 4)The coolant ejection from the tip exit in the sharp bend can decrease the mixing speed of the secondary vortices downstream of the bend. 5)The tip ejection from the trailing edge exits and film holes can reduce of the size of the secondary vortices downstream of the bend.

Accurate prediction of the interfacial area concentration is essential to successful development of the interfacial transfer terms in the two-fluid model. Mechanistic modeling of the interfacial area concentration entirely relies on accurate local flow measurements over extensive flow conditions and channel geometries. From this point of view, accurate measurements of flow parameters such as void fraction, interfacial area concentration, gas velocity, bubble Sauter mean diameter, and bubble number density were performed by the image processing method at five axial locations in vertical upward bubbly flows using a 1.02 mm-diameter pipe. The frictional pressure loss was also measured by a differential pressure cell. In the experiment, the superficial liquid velocity and the void fraction ranged from 1.02 m/s to 4.89 m/s and from 0.980% to 24.6%, respectively. The obtained data give near complete information on the time-averaged local hydrodynamic parameters of two-phase flow. These data can be used for the development of reliable constitutive relations which reflect the true transfer mechanisms in two-phase flow. As the first step to understand the flow characteristics in mini-channels, the applicability of the existing drift-flux model, interfacial area correlation, and frictional pressure correlation was examined by the data obtained in the mini-channel.

Abstract Semiconductor Test Site structures were analyzed using an EBIRCH (Electron Beam Induced Resistance CHange) system. Localization of a RX (active area) to PC (gate) short was achieved with resolution that surpassed that of OBIRCH (Optical Beam Induced Resistance CHange). A voltage breakdown test structure at Metal 1 was stressed in the system, giving isolation to the specific contact. A five-fin diode macro was examined, and it is believed that the electrically active diffusions were imaged as individual fins from Metal 1. A series of ring oscillator devices were examined in steady state condition, and careful consideration of the image supports a hypothesis that Seebeck effect, from heating material interfaces in an EBIRCH system, is the reason for the “dipoles” reported in earlier literature.

Most existing person re-identification methods are effective in short-term scenarios because of their appearance dependencies. However, these methods may fail in long-term scenarios where people might change their clothes. To this end, we propose an adversarial feature disentanglement network (AFD-Net) which contains intra-class reconstruction and inter-class adversary to disentangle the identity-related and identity-unrelated (clothing) features. For intra-class reconstruction, the person images with the same identity are represented and disentangled into identity and clothing features by two separate encoders, and further reconstructed into original images to reduce intra-class feature variations. For inter-class adversary, the disentangled features across different identities are exchanged and recombined to generate adversarial clothes-changing images for training, which makes the identity and clothing features more independent. Especially, to supervise these new generated clothes-changing images, a re-feeding strategy is designed to re-disentangle and reconstruct these new images for image-level self-supervision in the original image space and feature-level soft-supervision in the disentangled feature space. Moreover, we collect a challenging Market-Clothes dataset and a real-world PKU-Market-Reid dataset for evaluation. The results on one large-scale short-term dataset (Market-1501) and five long-term datasets (three public and two we proposed) confirm the superiority of our method against other state-of-the-art methods.
