Discrepancy Analysis of Load–Displacement in the Combination Space for Concrete Box Girder Assessment

The combination space concept had its origin in the theory of subspace and combinatorics. The combination space may be treated as the space reconstruction through combination, as well as the subspace one. Several new analytical methods are proposed based on combination principles applied to some operations. Under progressing structural damage, simple raw data cannot adequately characterize continuously changing processes and provide early prevention of considerable damage or loss of resistance to hazardous failure. Therefore, the data need to be further processed to find new criteria and factors of damage assessment. Three evaluation methods were experimentally established with the combination space. For the damage assessment and its early prevention, some factors are also proposed such that the combination space method can find the structural change earlier than the original data space. In the case of the the disparity between different conditions and the initial state, this method can contribute to the structure recovery, preventing its failure.

Global water cycle and remote sensing big data: overview, challenge, and opportunities

ABSTRACTThe Earth’s water cycle involves energy exchange and mass movement in the hydrosphere and thus sustains the dynamic balance of global hydrologic cycle. All water cycle variables on the Earth are closely interconnected with each other through the process of energy and water circulation. Observing, understanding and predicting the storage, movement, and quality of water remains a grand challenge for contemporary water science and technology, especially for researches across different spatio-temporal scales. The remote sensing observing platform has a unique advantage in acquiring complex water information and has already greatly improved observing, understanding, and predicting ability of the water cycle. Methods of obtaining comprehensive water cycle data are also expanded by new remote sensing techniques, and the vast amount of data has become increasingly available and thus accelerated a new Era: the Remote Sensing Big Data Study of Global Water Cycle. The element inversion, time and space reconstruction, and scale conversion are three key scientific issues for remote sensing water cycle in such Era. Moreover, it also presents a huge opportunity of capitalizing the combinations of Remote Sensing and Big Data to advance and improve the global hydrology and water security research and development, and uncork the new bottlenecks.

Using Artistic Expression as A platform for Learning About Children

Abstract Introduction: We perceive artistic expression as a suitable form of knowledge, investigation, and construction of understanding through the use of creative representation. The main goal of a broader conceived research then is to explore the prospects of that same artistic expression as a personal representation of a child and develop possible pedagogical diagnostics. The presented study is focused on detecting the level of trauma of refugee children and helping them to get through their suffering using artistic and pedagogical diagnostics of expression. The inquiry was carried out over two months with five children. Methods: Methods of observation, content analysis, and unstructured interviews were used during the research. Several themes were employed in meetings, but for the purpose of this paper we will analyze only one – that being “my house”. This theme was aimed through relaxation activities with clay, finger games, own world, reconstruction, and imagination of new space. It was a joint work that reflected children’s experiences using artistic expression with the clay. Results: Clearly, from their own creation, children transformed their house into abridge, which could be interpreted as a transition to a better house than they have experienced. Signs that appeared in children’s creations led to following interpretations and communications that brought us closer to the children’s issues which, in turn, were often related to the disturbance they had experienced and are still experiencing. Conclusions: It is precisely the art expression that proved to be the right mean for eliminating negative emotions and consequent problems arising from trauma. The effort of art expression is that the child, on their initiative, could break the barrier of secrecy related to his or her creation and could look for the connection between their own creation and their inner experience.

Identifying the Impacts of Social, Economic, and Environmental Factors on Population Aging in the Yangtze River Delta Using the Geographical Detector Technique

Under the background of social transformation and space reconstruction, population aging in China is becoming more and more diverse and complex. “Aging before getting rich”, a notion in population and economic development, has been a serious threat to sustainable development in China. On the basis of town- and street block-scale data from the Fifth and Sixth National Census in the Yangtze River Delta, we studied spatial distribution characteristics of population aging using global Moran’s I and hotspot analysis, and applied the geographical detector technique to explain the spatial heterogeneity of population aging. Several conclusions were drawn. (1) The promotion and replacement of aging coexist. Cluster of aging degree exhibits an increasing trend. Population aging is more severe in suburban areas than urban areas. (2) Migration is the main factor affecting the spatial heterogeneity of population aging. Per capital GDP and road network density are the second most influential factors. By contrast, the relief degree of land surface and the air quality index minimally influence population aging. The mechanisms of aging in various regions are affected by varying development levels. (3) The interaction among social, economic, and environmental factors enhances their effects and, thus, interacting factors have a greater influence on population aging than any single factor. The findings of this study have significant implications for local inhabitants and policy makers to address the population aging challenge in achieving sustainability of society, economy, and environment.

Immigration and the city: between state planning and residents’ practices and representations

This paper proposes to explore the role of immigration in the making of places. Departing from the assumption that “[…] the reconstruction of spaces and places within the City [i]s an active part of the reordering of the wider relations within which the City is set […]” (Massey et al. in City worlds. Routledge in association with the Open University, London, p 107, 1999), it addresses the relations between place, placemaking and immigration. The article draws on an empirical study carried out in an Israeli town located at the border of Lebanon, which was established in the 1950s with the purpose of settling new Jewish immigrants. It stages the life stories of various informants to the research, and the embodied character of these experiences, which all contribute to the production of the place under scrutiny. This micro-history of a place enables to identify the current immigration policy in place, and the motives which underlie it. As the article demonstrates, the narratives of each informant, inscribed in collective patterns, show the extent to which immigration is a crucial issue through which the city repositions itself within national narratives of nationbuilding. Additionally, they inform the transformations of power relations both in and out of the city, and the way the ‘imaginaries of place’ (Walker and Leitner in Urban Geogr 32(2):156–178, 2011) have shifted.

Visceral realities: The reconstruction of historic space

This paper examines unconventional interiors that “over imagine” the narrative of historic space. Reconstructions test not only historic accuracies but question spatial concerns and resulting atmosphere. The spaces to be interrogated are committed to providing a visceral experience whether or not they possess the rigors of taste, design, and scholarship. Examining spaces that reconstruct history is valid path to assessing the emotional quality of the interior and immersive historic constructs can be viewed as lessons for contemporary space making.

Outdoor Lighting Design Teaching Exploration with Creative Thinking as Its Core

Creative thinking is the ability to think creatively. It is of great guidance for the development of lighting design major to combine the spirit of innovation and the advantage of creativity when designing. Based on intention extraction, space reconstruction, environmental narrative and system construction, this paper, integrating creative thinking construction into the task of the “Four Orders of Design” in outdoor lighting design, aims to help lighting design majors to form creative thinking and make an organic whole of technology and art in lighting design projects.

State Identification of ECS Turbine Bearing Based on Fractal Dimension

According to nonlinear characteristics of vibration signals measured on the turbine used in the aircraft environment control system (ECS), the ensemble empirical mode decomposition (EEMD) together with fractal dimension analysis is investigated in the paper to extract characteristic quantities for the goal of fault diagnosis of turbine bearings. Firstly, in order to filter noise signal vibration and advance signal‐to‐noise signals under different statements of bearings, including normal bearing, inner ring fault, outer ring fault, and cage fault, are decomposed by EEMD. Then correlation dimension of those signals phase is calculated, contrasted, and analyzed after space reconstruction. The experimental result shows that the correlation dimension, as nonlinear geometric invariants, can be used as the characteristic quantity of ECS turbine bearing on running state. Moreover, this method can accurately and effectively identify the running state of the bearing.

Prevention and treatment of peritoneal laceration in the laparoscopic totally extraperitoneal hernia repair during learning curve

Objective To explore the causes and managements of peritoneal laceration in the laparoscopic totally extraperitoneal (TEP) hernia repair during learning curve. Methods The retrospective cross-sectional study was conducted. The clinical data of 120 patients with inguinal hernia who underwent laparoscopic TEP hernia repair in the Third Affiliated Hospital of Anhui Medical University (98 patients) and Anhui Provincial Hospital (22 patients) during surgeons′ learning curve between February 2012 and January 2017 were collected. Patients underwent laparoscopic TEP hernia repair, meshes were intraoperatively placed and then fixed by medical glue. Observation indicators: (1) intraoperative situations: surgical procedure, operation time, using of mesh, intra-operative peritoneal laceration; (2) postoperative situations: time to anal exsufflation, time for fluid diet intake, occurrence of complications, duration of hospital stay; (3) follow-up: number of patients receiving follow-up, follow-up time, recurrence of hernia during follow-up, pain in inguinal region, intestinal adhesion and obstruction induced abdominal pain, incisional infection. Follow-up using outpatient examination and telephone interview within 10 days postoperatively and using telephone interview at 10 days postoperatively was performed to detect the recurrence of inguinal hernia, pain in inguinal region, intestinal adhesion and obstruction induced abdominal pain and incisional infection up to May 2017. Measurement data with normal distribution were represented as ±s. Results (1) Intraoperative situations: of 120 patients, 112 underwent laparoscopic TEP hernia repair, 5 converted to laparoscopic transabdominal preperitoneal hernia repair and 3 converted to open surgery due to adhesion between hernial sac and surrounding tissues induced bleeding of separation. Total operation time of 120 patients was (71±13)minutes, including (63±7)minutes in 106 patients with unilateral hernia and (79±11)minutes in 14 patients with bilateral hernia. All the patients used intraoperatively meshes of 10.0 cm×15.0 cm and 16.0 cm×10.8 cm. Forty-eight patients had intraoperative peritoneal laceration, peritoneal laceration occurred for reconstruction of preperitoneal space in 10 patients, separation of anterolateral preperitoneal space in 11 patients and improperly operating equipment or hernial sac in 27 patients. Of 48 patients with peritoneal laceration, 40 continued to finish operation through acupuncturing into the abdominal cavity for exsufflation and then received peritoneal suture and repair, including 5 with recurrence of indirect inguinal hernia (receiving tissue repair) undergoing peritoneal repair through opening hernial sac, and 8 intraoperatively converted to other or open surgery. (2) Postoperative situations: time to anal exsufflation and time for fluid diet intake in 120 patients were (18±4)hours and (15±6)hours. Of 120 patients, 14 had postoperative complications, scrotal emphysema of 6 patients disappeared in 24 hours and inguinal and scrotal seroma of 8 patients disappeared after puncture treatment. All the patients were discharged from hospital in 2 days postoperatively. (3) Follow-up: 112 of 120 patients were followed up for 3-65 months, with a median time of 31 months. During follow-up, there was no occurrence of recurrence of hernia, pain in inguinal region, intestinal adhesion and obstruction induced abdominal pain and incisional infection. Conclusion During surgeons′ learning curve, identifying anatomy of the groin clearly, a right way to treat the hernia sac and broken peritoneum in the operation can ensure the smooth completion of the laparoscopic TEP hernia repair. Key words: Hernia, inguinal; Peritoneal laceration; Laparoscopy

Planning Interior and Exterior Spaces of a Modern Gymnasium: Case Study Yubei Stadium

With the trend of adaptive reuse of old buildings and the continuous development of the sports industry in China, transforming stadiums that are no longer suitable has become a pressing issue. Based on this, the basic problems of adaptive transformation of urban stadium were discussed, and the motivation and principles of stadium reconstruction were analyzed. From the sense of place context, the openness of the interface and the integrity and diversity of the environment space, the reconstruction of the exterior space of the stadium was planned. In the reconstruction of the interior space of the stadium, the use of the interior space of the stadium and the needs that should be satisfied were mainly planned. Taking Yubei stadium in Chongqing as an example, the analysis was carried out. The planning structure, functional requirements, transportation, environment, spatial integrity and diversity were studied, and the current development trend of the stadium was reflected from the planning of interior and exterior space of gymnasium. In conclusion, this study provides a theoretical basis for the adaptive transformation of the stadium, and it is of great significance.

Rate-Distortion Bounds for Kernel-Based Distortion Measures

Kernel methods have been used for turning linear learning algorithms into nonlinear ones. These nonlinear algorithms measure distances between data points by the distance in the kernel-induced feature space. In lossy data compression, the optimal tradeoff between the number of quantized points and the incurred distortion is characterized by the rate-distortion function. However, the rate-distortion functions associated with distortion measures involving kernel feature mapping have yet to be analyzed. We consider two reconstruction schemes, reconstruction in input space and reconstruction in feature space, and provide bounds to the rate-distortion functions for these schemes. Comparison of the derived bounds to the quantizer performance obtained by the kernel K -means method suggests that the rate-distortion bounds for input space and feature space reconstructions are informative at low and high distortion levels, respectively.

A white-box framework to oversee archaeological virtual reconstructions in space and time: Methods and tools

The goal of this paper is to present original methods and visual tools able to formally document the scientific processes behind an archaeological virtual reconstruction, namely a new version of the Extended Matrix (EM 1.1) and the Extended Matrix Framework (EMF 1.1). The proposed approach aims to improve the EM as well as methods and tools for 3D query, visualization, and inspection of extended matrices in order to solve current bottlenecks and issues with the integration of 3D virtual environments and rich semantic descriptions (EMF). A real case scenario is provided to present the steps involved in a reconstruction project using EM/EMF: the Great Temple of the ancient Roman town Colonia Dacica Sarmizegetusa.

Archaeoacoustics of Mexico City's cathedral

We consider the acoustics of the architectural design of Mexico City's Cathedral. Using measurements of the impulse response of the building and a virtual reconstruction of the architectural space, the reconstruction of the soundscape is developed with statistical and geometric methods and a standard computational platform (EASE). This reconstruction and contrast of experimental and simulated results allow to pose meaningful hypotheses related to the acoustical functionality of this temple, which played and continues to play a significant role in the religious and social activities of the country. We also present possible connections with other architectural, historical, and musicological aspects.

Abstract WP366: Quantitative Diffusion Tensor Tractography of the Corticospinal Tract as a Predictive Outcome Parameter in Patients With Intracerebral Hemorrhage

Introduction: Intracerebral hemorrhage (ICH) is a devastating disease with poor outcome. Established predictive markers include initial hematoma size, clinical status, intraventricular bleeding and age. However, prognostic assessment is often difficult which additionally burdens patients and caregivers and complicates rehabilitation. Functional outcome especially relies on motor function which is correlated with the integrity of the Corticospinal Tract (CST). Diffusion Tensor (DT) Tractography allows visualization of the CST. However, sufficient data about the prognostic impact of quantitative CST assessment is lacking. Methods: We prospectively enrolled patients with spontaneous supratentorial ICH admitted between 08/2012 und 08/2015. Informed consent and ethical approval was obtained. MRI scan was performed on day 5±1. DT data was normalized to MNI Space and Q-Space diffeomorphic reconstruction was performed using DSI-studio. CST was reconstructed based on quantitative anisotropy (QA) using the CST region (JHU white matter atlas) as seeding region and cerebral peduncle as region of interest (ROI). Fractional Anisotropy (FA) and QA were analyzed in the seeding and ROI region and in the posterior limb of the internal capsule (PLIC). Dichotomized modified Rankin Scale on day 90 (favorable outcome = mRS 0-2) was assessed as primary outcome variable. Results: 33 patients, mean age 70.7 y (standard deviation (SD) 12.9), 12 male, 21 with lobar hemorrhage, mean ICH volume on admission 16.5 (SD 11.3) cm 3 were included. 16 patients had a favorable outcome on day 90 (median mRS 3 (IQR 1-3.5). Mean number of reconstructed CST fiber pathways ipsilateral to ICH was higher in patients with favorable outcome (11343 (SD 8201)) than in patients with unfavorable outcome (4868 (SD 3221), p=0.008). Median QA and FA values in the PLIC ipsilateral to ICH were also higher in patients with favorable outcome (QA: 18.9 (IQR 16.2-23.3) vs. 14.6 (IQR 11.7 - 17.7), p=0.016, FA: 0.49 (IQR 0.45-0.53) vs. 0.41 (IQR 0.38-0.49), p=0.026). Conclusion: Higher FA- and QA-values in the PLIC and higher numbers of CST fiber pathways ipsilateral to ICH seem to be associated with a favorable outcome. DT Imaging may turn out as a useful quantitative predictive marker in the acute phase of ICH.

Three-dimensional panoramic sensor based on a variable-frequency fringe pattern.

This paper aims to develop a 3D panoramic sensor with a catadioptric imaging system. First, the fringe pattern is designed in a polar coordinate system to match the dimensions of a hyperbolic mirror. Second, a variable-frequency fringe pattern is proposed to obtain the constant-frequency reconstruction in real space. Experiments are conducted to verify system accuracy and feasibility, and the experimental results show the effectiveness of the proposed 3D panoramic sensor.

Compressive holographic video.

Compressed sensing has been discussed separately in spatial and temporal domains. Compressive holography has been introduced as a method that allows 3D tomographic reconstruction at different depths from a single 2D image. Coded exposure is a temporal compressed sensing method for high speed video acquisition. In this work, we combine compressive holography and coded exposure techniques and extend the discussion to 4D reconstruction in space and time from one coded captured image. In our prototype, digital in-line holography was used for imaging macroscopic, fast moving objects. The pixel-wise temporal modulation was implemented by a digital micromirror device. In this paper we demonstrate 10× temporal super resolution with multiple depths recovery from a single image. Two examples are presented for the purpose of recording subtle vibrations and tracking small particles within 5 ms.

Spatializing Politics: Essays on Power and Place ed. by Delia Duong Ba Wendel and Fallon Samuels Aidoo

Reviewed by: Spatializing Politics: Essays on Power and Place ed. by Delia Duong Ba Wendel and Fallon Samuels Aidoo Darren Purcell (bio) Spatializing Politics: Essays on Power and Place. Edited by Delia Duong Ba Wendel and Fallon Samuels Aidoo. Cambridge, MA: Harvard University Press, 2016. Pp. 432. $24.95. Writers embracing the spatial turn in several disciplines, including the humanities, often overlook a field engaged with the social processes behind spatial arrangements of power: geography. Fortunately, the editors avoid this myopia by bringing together authors engaged across disciplinary boundaries. Invoking geographical theorists such as Harvey, Massey, Mc-Cann, and Soja, the level of intellectual cross-pollination is refreshing. The editors invoke the term "spatial epistemology" to frame case studies focused on the spatially contingent nature of political power. The essays shed light on varying forms of state power and of resistance efforts in order to articulate dissent over the reconstruction of space that invariably benefits the entrenched interests driving the state. The first two sections cover the themes of contentious politics and the politics of consensus. Margo Shea's take on urban renewal and the spatial politics of governance in Northern Ireland highlights the spatial resistance after implementation of policies aimed at making a space of political resistance more governable. Kerry Chance's examination of South Africa's transit [End Page 1074] camps and the development of new slums as infrastructure highlights efforts to enhance the state's ability to govern an evicted populace. Anh-Thu Ngo provides a discussion of the reworking of Ho Chi Minh City and the contestation of those visions with art and creative energies. Fallon Aidoo's exploration of efforts to contest the reworking of spaces related to railroads that crossed class lines provides insight into how such coalitions can be forged. Biopolitics is the organizing theme for a three-essay section, including Joy Knoblauch's consideration of community mental health centers, their architectural design, and their role in communities. Melany Park looks at North Korea's penal colonies and their practices upon the body through a narrative utilizing texts from various interviews and the stage play Yoduk Story. Disabled bodies and how architecture is designed to accommodate the Americans with Disabilities Act is the focus of Wanda Liebermann's chapter, which highlights how disability was defined and then incorporated into the Architectural Graphic Standards so that only certain bodies' accommodations are addressed. The final section is the politics of expertise. Orly Linovski argues that there are clear issues with the development of a public space through the use of design consultants. Michael Mendez's narrative about Oakland's grassroots environmental efforts shows that they have been effective in articulating climate change issues in such a way as to transform them into tangible, knowable impacts that resonate with communities and drive actions at the city scale. Finally, H. Fernando Burga chronicles efforts to plan Miami-Dade County in the face of changing demographics, immigration trends, and refugee flows, allowing for a more nuanced understanding of the Cuban-American political dynamics at the local scale. Two of the essays stand out for their engagement of politics at multiple scales. First is Delia Duong Ba Wendel's work on the 2004 radio program Musekeweya. The program created a fictional version of the challenges facing Rwandan society after the deployment of differences in economic status between the Hutus and the Tutsi nations during the 1994 genocide. The series narrates a parallel history through the use of spatial metaphors and fosters a space of reconciliation and a new spatial conception of the future. The value of a discursive landscape is highlighted by Ryne Clos's essay on the dormant Tiscapa volcano in Managua, Nicaragua, the site of political symbolism on the landscape in two distinct eras, the Somoza and Sandinista regimes. Contrasting Rancièrian approaches to the state with Althusserian ones, Clos highlights Somoza's efforts to insure consensus in what the author terms "… 'his' Nicaragua …" versus the Sandinistas' respatialization through democratization of the Tiscapa. The book as a whole represents a consistent engagement with various forms of spatial politics across scales, but always reminds the reader of individual-scale processes. These chapters are well-theorized case studies, as...

Value orientation in higher education: Problems and prospects from sustainable development perspectives

Human beings adapt themselves according to the environment they live in and create their own space among others for better survival in society. The geographical and societal space they acquire gives them a sense of security and a sense of belongingness. If this space is taken away by dislocating them, it leads to mental and physical vacuum which is experienced across generations. A similar problem of space can be traced back in the history of India, when the partition of the country into India and Pakistan took place. People who were living in one town from many generations were dislocated on the basis of religion they belonged to. Feeling of security and belongingness they once enjoyed was snatched from them and they became an outsider in their own country. They were forced to migrate from one place to another and were left with only alternative, to readept themselves to create their new identity. Real accounts of such vacuums caused by partition can be seen in Bhisham Sahni’s novel Tamas . Hindu and Sikh families of Small-Town province were caught in the fury of political turmoil of Partition due to religious riots that broke out leading to massacre, suicide, abduction and rape. Peace loving people who enjoyed space in their homeland were dislocated in the name of religion. Hindus and Muslims of one town who were friends and neighbors all their life turned into enemies and fought with one another to destroy the space and identity of people on the basis of petty issues. In the proposed paper the researcher aims to analyse the effect of partition in deconstruction and reconstruction of space and the strategies adopted by characters to relocate themselves in alien environments and geographical space. Keywords: Place, Space, Partition, Migration, Dislocation, Belongingness.

Thermophysical aspects of reconstruction of cold roof spaces

The results of theoretical studies of thermal modernization of cold roof floor. The designs of overlap of long-life roofs of public buildings were considered. Overlap of these buildings are made by wooden or concrete beams and made of concrete slabs with upward edges. The problems of thermal modernization of these designs are consideration of the impact of heat-conducting inclusions on the resistance to heat. The heat-conducting inclusions of constructions are beams and vertical edges of the slabs. The results of calculations of the temperature fields were used for the analysis. The research was carried for the two temperature zones which Ukraine’s territory is divided into. The analysis of thermal protection level of structures overlap was made. The magnitude of the impact of heat-conducting inclusions on resistance to heat after thermal modernization of cold roof floor was observed. The analysis showed that the thermal protection properties of structures less than standard, therefore the insulation of areas with heat-conducting inclusions is required. The options of insulation of these areas were considered. The optimal insulation options with the least amount of additional insulation over the heat conductive areas were selected.
