Semi-Automated Generation of Road Transition Lines Using Mobile Laser Scanning Data

This paper recognizes the research gaps and difficulties in generating transition lines (the paths that pass through a road intersection) in road intersections from mobile laser scanning (MLS) point clouds. The proposed method contains three modules: road surface detection, lane marking extraction, and transition line generation. First, the points covering the road surface are extracted using the voxel-based upward growing and the improved region growing. Then, lane markings are extracted and identified according to the multi-thresholding and the geometric filtering. Finally, transition lines are generated through a combination of the lane node structure generation algorithm and the cubic Catmull–Rom spline algorithm. The experimental results demonstrate that transition lines can be successfully generated for both T- and cross-intersections with promising accuracy. In the validation of lane marking extraction using the manually interpreted lane marking points, the method can achieve average precision, recall, and F1-score of 90.80%, 92.07%, and 91.43%, respectively. The success rate of transition line generation is 96.5%. Furthermore, the buffer-overlay-statistics (BOS) method validates that the proposed method can generate lane centerlines and transition lines within 20-cm-level localization accuracy from the MLS point clouds.
Experimental Investigations on Variable Compression Ratio Diesel Engine Fueled with Mahua Oil and Diesel Blends

India is taking a gander at renewable option fuel sources to decrease its reliance on imported products of oils. As India imports 70% of the oil, the nation has been hit hard by expanding expense and instability. As of late the biomass assets are being utilized as option powers and successful utilization of those energizes is picking up unmistakable quality as a substitute approach to tackle the issue of a dangerous atmospheric deviation and energy crisis. Among all the option powers existing mahua oil is additionally one. Mahua oil is extracted from mahua seed oil. The properties of these blends were observed to be practically identical to diesel and affirming to the American standards, experiments are conducted on variable compression ratio diesel engine, which is water cooled, rated at a speed of 1500 rpm. Unique mixes of transesterified mahua oil, diethyl ether with diesel were tested at different proportions and at different compression ratios like 14:1, 16:1, 18:1 and 20:1. From the experimental results we have identified that Slight increase in brake thermal efficiency and decrease in specific fuel consumption compared to that of diesel. The expense of transesterified mahua oil is low contrasted with the expense of diesel. Henceforth, mahua oil blends with diesel is more economical. However, this is a partial solution to the growing diesel scarcity in developing nations like our own.
Sustainable Design using Computational Fluid Dynamics in the Built Environment – A Case Study

In recent years, end users have become more concerned with the human experience and the personal comfort of the individual is becoming more important in the design of the built environment. Computational Fluid Dynamics (CFD) is a tool that permits assessment of personal comfort. CFD is a stream of fluid mechanics that utilises numerical methods to analyse and solve problems involving fluid flows. While research applications of CFD are developing, as is the use of CFD in the aerospace and Formula1 industries, the use of CFD in Civil Engineering applications is currently at the cutting edge. This paper will investigate the use of computational fluid dynamics as a complementary approach to wind tunnel testing for pedestrian comfort. The results showcased here were determined through a consultancy project by the team at Arup, Dublin. On determining potential wind problems, mitigation measures were proposed and tested in CFD to prove that the mitigation measures were effective. These proposed changes were incorporated into the final design and as a result planning permission was awarded for the development. This work is exemplar of how, from the very conception of the project design, new technological advances lead to a better built and sustainable environment for all.

medis berupa fasa ɣ -Co yang berstruktur FCC. seringkali fasa metastabil Co 7 Mo 6 muncul. Munculnya fasa Co 7 Mo 6 ini akan menurunkan komposisi dari fasa ɣ -Co. Studi ini bertujuan untuk mensintesis fasa ɣ -Co tanpa diikuti munculnya fasa Co 7 Mo 6 menggunakan kombinasi homogenisasi 1200 o C dan hot rolling yang dilanjutkan dengan pendinginan. Paduan yang digunakan adalah ingot Co 26 Cr 6 Mo 0.18 N. Pendinginan dilakukan dengan tiga variasi yaitu menggunakan air dingin, air dan udara. Transformasi ABSTRACT Co-Cr-Mo alloy is a material that widely used for bioimplant in the medical field due to its corrosion resistance and mechanical properties . Structurally, recommended Co-Cr-Mo alloys for medical applications are ɣ-Co phase which has an FCC structure . But, Co 7 Mo 6 metastable phase often occurs after its synthesis . The formation of Co 7 Mo 6 phase will decrease the composition of ɣ-Co phase . This study aimed to synthesize ɣ-Co phase without following the appearance of Co 7 Mo 6 phase using a combination of 1200 o C homogenization and hot rolling followed by cooling treatment . The alloy used was Co 26 Cr 6 Mo 0.18 N ingot . Cooling treatments were done using the variation of cold water, water and air . The transformation of the crystal structure from the primitive cubic to the FCC occurs during water and air cooling treatments which means that ɣ-Co phase is successfully formed by those cooling treatments . However, Co 7 Mo 6 phase is still formed on the water cooling treatment while none of Co 7 Mo 6 occurred on the air cooling treatment . Structurally, air cooling treatment produces most stable ɣ-Co phase than the others . However, brittle ɛ-Co phase as a partial dislocation is formed after air cooling treatment due to imperfection of hot rolling treatment.
E2-VOR: An End-to-End En/Decoder Architecture for Efficient Video Object Recognition

High-resolution video object recognition (VOR) evolves so fast but is very compute-intensive. This is because VOR leverages compute-intensive deep neural network (DNN) for better accuracy. Although many works have been proposed for speedup, they mostly focus on DNN algorithm and hardware acceleration on the edge side. We observe that most video streams need to be losslessly compressed before going online and an encoder should have all the video information. Moreover, as the cloud should have abundant computing power to handle sophisticated VOR algorithms, we propose to take a one-shot effort for a modified VOR algorithm at the encoding stage in cloud and integrate the full VOR regeneration into a slightly extended decoder on the device. The scheme can enable lightweight VOR with server-class accuracy by simply leveraging the classic and economic video decoder universal to any mobile device. Meanwhile, the scheme can save massive computing power for not repetitively processing the same video on different user devices that makes it extremely sustainable for green computing across the whole network. We propose E2-VOR, an end-to-end encoder and decoder architecture for efficient VOR. We carefully design the scheme to have minimum impact on the video bitstream transmitted. In the cloud, the VOR extended video encoder tracks on a macro-block basis and packs intelligent information into the video stream for increased VOR accuracy and fast regenerating process. On the edge device, we extend the traditional video decoder with a small piece of dedicated hardware to enable the efficient VOR regeneration. Our experiment shows that E2-VOR can achieve 5.0× performance improvement with less than 0.4% VOR accuracy loss compared to the state-of-the-art FAVOS scheme. On average, E2-VOR can run over 54 frames-per-second (FPS) for 480P videos on an edge device.

Open Research Online An abyssal carbonate compensation depth overshoot in the aftermath of the Palaeocene–Eocene Thermal Maximum

During the Paleocene-Eocene Thermal Maximum (PETM, ~56Ma), thousands of petagrams of carbon were released into the atmosphere and oceans in just a few thousand years (kyr), followed by gradual sequestration over ~200 kyr. Theory and carbon cycle models predict that if silicate weathering is one of the key negative feedbacks responsible for the removal of this carbon, a period of calcium carbonate oversaturation (relative to pre-event levels) should have occurred during the event’s recovery. This could be reflected in the marine geological record as an over-deepening of the calcite compensation depth (CCD). However, despite previous evidence for enhanced calcium carbonate accumulation at shallow depths following the PETM, no direct observations of this hypothesized CCD over-deepening have yet been made. Here we present evidence from two new North Atlantic sections that test this hypothesis. Consistent with existing records, we find higher calcite accumulation during the PETM recovery phase compared to pre-event accumulation at a mid-abyssal site (U1409), demonstrating intensified post-PETM over-deepening. and overshoot initial Our that PETM both positions the P-E nannofossil provided coarse-resolution records of wt% CaCO 3 The surface of core at 1-2 cm-resolution Oceanography using Avaatech X-ray fluorescence (XRF) core scanners. Estimates of the total abundance of calcium (Ca) and iron (Fe) were obtained by scanning cores at an energy level of 10kV, current of 500 uA, count time of 20 sec, and measurement area of 10 x 12 mm. Estimated wt% CaCO 3 records were generated by regressing shipboard wt% CaCO 3 measurements 30 against the natural logarithm of XRF-derived Ca/Fe ratios. For stable isotope analyses, samples were collected at ~5cm resolution from Site U1409 and 10cm resolution from Site U1403, freeze dried, homogenized with mortar and pestle, and analyzed for δ 13 C carb on a ThermoFisher MAT 253 stable isotope mass spectrometer coupled to a Kiel IV carbonate device using standard dual-inlet techniques. In addition, samples from Site U1409 were washed and sieved, and specimens of the benthic foraminifera Nuttalides truempyi were picked from the 150-200 and 212-300μm size fraction. Where possible, 3-8 of these specimens from each sample were run using the δ 13 C carb methods described above. For δ 13 C org analysis of Site U1403, homogenized sample powders were de-carbonated in 1M HCL and washed in de-ionized water. δ 13 C org was measured using a Thermo-Finnegan MAT 253 mass spectrometer coupled to a via a Conflo IV interface optimized for the measurement of samples with low organic carbon abundances.

Hypocomplementemia during tocilizumab treatment

Abstract Hypocomplementemia has been reported in patients with rheumatoid arthritis treated with tocilizumab (TCZ), but its long-term consequences are unknown. We assessed the long-term outcome of patients treated with TCZ who developed hypocomplementemia regarding serious bacterial infections or autoimmune diseases (AID). The charts of patients treated with TCZ at two rheumatology centers were reviewed retrospectively. Data regarding patients’ age, gender, disease duration, autoantibodies status, previous or concomitant treatments, blood counts, liver enzymes, C3 and C4 levels at baseline and during TCZ treatment, episodes of infections, allergic reactions, and AID were analyzed. Univariate analysis was used to compare patients with low C3, C4 levels versus patients with normal C3, C4 levels. Variables that were statistically significant associated or tended to be associated with low C3 or C4 were included in multiple variable logistic regression. Of 132 patients treated with TCZ, 108 had serial measurements of serum complement concentration. Thirty-three (30%) patients developed low C4 levels and 23 (21%) had also low C3. Mean TCZ treatment period was 4.9 years (range, 1–14 years). All patients had normal complement levels at baseline. Leukopenia occurred in 18 (16.7%) patients, 14 of whom (77%) had low complement. Persistent leukopenia was observed in 8% and 5.3% of patients with normal C3 and C4 levels, respectively, as opposed to 47% and 42% of patients with low C3 or low C4, respectively. Low C3, C4 levels correlated with prolonged TCZ treatment retention time and effectiveness. There were no serious bacterial infections or new onset AID. Hypocomplementemia during TCZ treatment was accompanied by leukopenia that correlated with treatment duration. Hypocomplementemia was not associated with serious bacterial infections or new onset AID. Decreased complement levels were associated with treatment longevity. The role of monitoring complement level in predicting treatment response or assessing disease activity deserves further investigation.
Clinical characteristics of 14 cases of severe Chlamydia psittaci pneumonia diagnosed by metagenomic next-generation sequencing

Abstract Introduction: The objective of this study was to explore the clinical, laboratory, and imaging features of severe Chlamydia psittaci pneumonia in order to improve early diagnosis and treatment success rates. Methods: We conducted a retrospective record review of 14 cases of severe Chlamydia psittaci pneumonia diagnosed by metagenomic next-generation sequencing technology in our hospital. We extracted and analyzed data on the clinical symptoms and signs, contact history, laboratory investigations, chest computed tomography, treatment, and clinical outcomes. Results: Of the 14 patients, 12 (86%) were male and two (14%) were female, with a mean age of 57 years (SD: 7 years). Eleven patients (79%) had a history of poultry contact. The main clinical manifestations were fever (n = 14, 100%), flu-like symptoms (n = 10, 71%), cough, sputum (n = 9, 64%), and dyspnea (n = 5, 36%). Blood tests revealed marked elevation of neutrophil percentage, C-reactive protein, procalcitonin, brain natriuretic peptide, and creatine kinase levels; slight elevation of aspartate aminotransferase, creatinine, urea, fibrinogen, and D-dimer levels; and decreased albumin, sodium, and calcium levels. Chest computed tomography showed bilateral lesions (n = 7, 50%), middle-lower lobe lesions (n = 10, 71%), lesions in multiple lobes (n = 9, 64%), consolidation shadows (n = 11, 79%), and pleural effusions (n = 11, 79%). The median time from disease onset to hospital admission was 4.5 days (interquartile range: 1–17 days); the mean length of hospital stay was 20.9 ± 8.5 days, and the mean time from admission to diagnosis was 5.1 ± 2.6 days. After diagnosis, patients were either treated with doxycycline alone or doxycycline combined with quinolones. All 14 patients developed respiratory failure and received invasive mechanical ventilation; two (14%) received veno-venous extracorporeal membrane oxygenation, four (29%) received continuous renal replacement therapy, and three (21%) died. Discussion and conclusion: A poultry contact history and typical flu-like symptoms are early indicators of Chlamydia psittaci pneumonia. Substantial elevations in procalcitonin, creatine kinase, and brain natriuretic peptide indicate severe disease. Metagenomic next-generation sequencing is useful for diagnosis. Early empirical antibiotic therapy with quinolones can reduce the mortality in critically ill patients.
Traditional Chinese medicine injections with activating blood circulation, equivalent effect of anticoagulation or antiplatelet, for acute myocardial infarction

Abstract Background In spite of a growing number in the use of percutaneous coronary intervention (PCI) in China, the mortality of acute myocardial infarction (AMI) has not decreased. Traditional Chinese medicine injections for Activating Blood Circulation (TCMi-ABC), equivalent effect of anticoagulation or antiplatelet, are widely used in China; however, the improvement of fatality towards AMI is unclear. Therefore, we intend to conduct a systematic review and meta-analysis to evaluate the efficacy and safety of TCMi-ABC in treatment with AMI. Methods Based on the “National Medical Products Administration of China,” TCMi-ABC with AMI treatment indication will be selected, including Danhong injection, Sodium Tanshinone IIA Sulfonate injection, Danshen Chuanxiongqin injection, and Puerarin injection. Randomized controlled studies will be searched from as follows: PubMed, Embase, the CENTRAL in Cochrane Library, Chinese Biomedical Literature Database (SinoMed), China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), and Wanfang Data Knowledge Service Platform. Two researchers will work independently on literature selection, data extraction, and quality assessment. The outcomes focus on the effects of TCMi-ABC on fatality of patients with AMI in hospitalization and in the long term, the incidence of malignant arrhythmia, left ventricular ejection fraction, and adverse events. RevMan 5.4. 1 software was used for mate analysis. Results This study will conduct a comprehensive literature search and provide a systematic synthesis of current published data to explore the efficacy and safety of TCMi-ABC for AMI. Conclusion This study will provide high-quality evidence for treatment of AMI with TCMi-ABC in terms of efficacy and safety, which may help clinicians make a better complementary treatment schedule of patients with AMI.
Towards the Development of a Typology of Big Data Analytics in Towards the Development of a Typology of Big Data Analytics in Innovation Ecosystems Innovation Ecosystems

The digital transformation of society and economy leads to fundamental changes in the planning and execution of innovation processes in organizations. Possibilities and application scenarios of digital, data-driven innovation are frequently discussed in academia and in industry, but a comprehensive and systematic examination of the various types and roles of big data analytics technologies in innovation ecosystems is currently missing. Organizations need support in identifying and implementing the new opportunities of big data analytics to generate value through innovation. Starting from the theoretical perspective of service-dominant logic, we present a three-dimensional conceptual framework with associated characteristics that can be used to derive different archetypes of big data analytics in innovation ecosystems. The findings will be further developed as part of a qualitative case study in the field of electromobility in Germany.
Workshop on human-centred learning analytics: A critical analysis based on the discussion of two case studies

There is a recently growing subcommunity of LA focusing on hu-man-centeredness that proposes a more user-centred approach to the learning analytics practice: Human-Centred Learning Analytics (HCLA). This approach focuses on three key elements that come into play and interact under the human activity umbrella: human factors, social factors and technology factors. Therefore, the main focus shifts from assuring that the artifact works as intended to enabling many individual or cultural conceptions to unfold into uninterrupted interfaces with technology. The workshop was organized by SNOLA (Spanish Network of Learning Analytics) and introduced two cases used to prompt the discussion of two LA tools designed following the HCLA approach. This paper presents the workshop and its results based on the discussion around the advantages and disadvantages of the two cases and their methodologies, objectives and findings according to participants’ insights and collaboration. The two main findings this paper contributes are focused on: 1. The HCLA approach, viewed and understood from the point of view of non-experts and experts of different levels of expertise and 2. The implications that HCLA has on the design process of the LA tools and artifacts. These two findings open more doors for research on the enhancement of the HCLA approach and effectiveness of the design process, therefore guiding the future directions of research on the same line of the presented findings
Phase Unwrapping with GAMMA ISP Technical Report, 13-May-2002

One of the most challenging aspects in the successful application of SAR interferometry (INSAR) is unwrapping the interferometric phase. The difficulties arise in attempting to find global optimization procedures with the best possible cost criteria for data that are both noisy and incomplete. Recent progress in this problem includes introduction of network flow optimization, and the use of triangular irregular networks for sparse data. Interferograms differ greatly in the difficulty to unwrap depending on the interferogram fringe complexity and correlation. We examine the characteristics of these types and present phase unwrapping strategies for each of these.
Spectral Analysis of Flow around Single and Two Crossing Circular Cylinders Arranged at 60 and 90 Degrees

Two modal decomposition techniques, including proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD), were used to identify the wake patterns past single and two crossing cylinders in 60° and 90° arrangements with gap ratio G = 4. The flow was simulated using direct numerical simulations (DNS) for Reynolds numbers Re = 100. From modal analysis, the flow’s spatial scale decreased with increasing modal frequency. Two main modes were identified in the wake of the cylinders, namely spatially antisymmetric and symmetric modes. Antisymmetric and symmetric modes were related to the cylinders’ vortex shedding and shedding vortices’ shift motion, respectively, whose frequencies were odd and even multiples of the cylinders’ lift force frequency. In addition, a low-frequency mode concerning the shadowing effect of the downstream cylinder (DC) in 90° arrangement was found in the wake of the DC centre.
