A Novel approach for Retrieval of Historical Monuments Images using Visual Contents and Unsupervised Machine Learning

In Recent Era monuments image identification and retrieval task is too complex than other dataset images due to its distinct features variation and complex architecture. Structure orientation also plays a vital role for identification and recognition of monuments images. Using content based image retrieval our proposed approach provides a solution of this problem. The aim of proposed work is to make an efficient model to retrieve correct monuments images using machine learning algorithm. Proposed approach extract the handcrafted features by using the RGB Histogram (fast) color features and Histogram of Oriented Gradient texture feature. To make a perfect cluster with minimum outliers of images we used unsupervised machine learning i.e. k-means clustering. This algorithm has been made the retrieval process fast by avoid the whole search for matching similarity in the complete dataset. The experiments show the performance of proposed approach which gives 97% accuracy for retrieval of monument images.
Evaluation of Operability for a Competition Wheelchair Using Manipulability

The objective of this study was to evaluate the operability for a competition wheelchair by estimating biomechanical parameters during the forward linear operation of a wheelchair using an inverse dynamics analysis. During operation of the wheelchair, the vector of ideal hand force in the posture of the arm was calculated using the reaction force between the hand and the wheel. Hand manipulability was defined as the angles between its vector and the vector of hand force estimated from the simulation. The effects of the design parameters for the wheelchair on manipulability were investigated by conducting simulations with changes in axle positions. As a result, it may be effective to set the axle to higher positions to increase the energy efficiency of the upper limbs during operation of the wheelchair. This indicates that adjustment of the axle position leads to improvement of operability of the wheelchair.
Comparative Studies On The Phytochemical Screening And In Vitro Antioxidant Activities Of Aqueous Extracts Of Garcinia Kola Stem And Root Barks

Phytochemicals are natural chemicals of plant origin that have implicated in anti-disease mechanism. Antioxidant are insulator of the process of the oxidation even at relatively small concentration and this have diverse physiological role in the body. They are naturally occurring in the medicinal plants, vegetables, leaves and roots that have defense mechanism and protect from various diseases as well inhibit, or delay the oxidation of other molecules by inhibiting the initiation or propagation of oxidizing chain reaction. Garcinia kola is a tropical flowering plant grown mainly in West and Central Africa. Garcinia kola is known for its anti-inflammatory and antioxidant properties. Therefore, comparative studies on the phytochemical screening and in vitro antioxidant activity on aqueous extracts of stem and root of Garcinia kola were investigated to assess their antioxidant properties in different antioxidant property determination assays. Aqueous extracts of Garcinia kola stem and root bark revealed the presence of tannins, resin, saponins, flavonoids, phenols, carbohydrates and alkaloids. In addition, the aqueous root bark extract of the plant contained phlobatanins and sterols while its stem bark aqueous extract contained terpenoids. The IC50 (μg/ml) values of the stem bark extract were 108.35 ± 7.70, 122.81 ± 3.98, 0.20 ± 0.01, 0.16 ± 0.01 and 0.43 ±0.01 for total antioxidant capacity (AAE), ferric reducing antioxidant activity (AAE), diphenyl picryl hydrazyl (DPPH) assay, nitric oxide (NO) scavenging activity and metal chelating activity respectively. On the other hand, the IC50 (μg/ml) values of the root bark extract were 31.54 ± 2.72, 30.50 ± 0.96, 2.26 ± 0.13, 4.36 ± 0.52 and 0.75 ± 0.04 for total antioxidant capacity (AAE), ferric reducing antioxidant activity (AAE), diphenyl picryl hydrazyl (DPPH) assay, nitric oxide (NO) scavenging activity and metal chelating activity respectively. Consequently, both the stem bark and root bark extracts generally exhibited remarkable in vitro antioxidant properties with respect to the parameters investigated.
PERFORMANCE OF A BIOTRICKLING FILTER EMPLOYING THIOBACILLUS THIOPARUS IMMOBILIZED ON POLYURETHANE FOAM FOR HYDROGEN SULFIDE REMOVAL

The removal of hydrogen sulfide (H2S) from contaminated airstream was studied in a biotrickling filter (BTF) packed with open-pore polyurethane foam as a carrier of Thiobacillus thioparus (DSMZ5368) with counter current gas/liquid flows. The effect of operating parameters on BTF performance was studied. Experiments were performed at different Empty Bed Residence Times (EBRT) from 9 to 45 seconds, and different initial H2S concentration from 25 to 85 ppm. The results showed reasonable performance of the BTF, in H2S removal from the synthetic gas stream. However, the performance was somewhat lower than other studies in BTF in which either Thiobacillus thioparus with other packings or polyurethane foam with other microbial cultures were used. The effect of liquid recirculation rate (LRR) in the range of 175-525 ml/min (0.46-1.34 m/h) on BTF performance was also studied. Results showed that increasing LRR from 175 to 350 mL/min resulted in significant enhancement of H2S removal efficiency, but further increase in LRR up to 525 mL/min had an insignificant effect. H2S elimination at different heights of the bed was studied and it was found that decrease in EBRT results in more homogeneous removal of the pollutant in BTF. Determination of microbial species in the BTF after 100 days performance showed that during BTF operation the only H2S degrading specie was Thiobacillus thioparus.

Ayrıca bağımsız değişken ile bağımlı değişken arasındaki doğrudan ilişkinin anlamlı olmamasına karşın bu ilişkide sosyal medya kullanım amaçları değişkeninin tam aracılık etkisi tespit edilmiştir.
Rational-Designed Hybrid Aerogels for Ultra-Flyweight Electrochemical Energy Storage

Hybridising 2D materials into 3D aerogels have attracted considerable interest in ultralight electrochemical energy storage devices. However, to optimise the device structure for more efficient charge storage and transport, a better understanding of the ratio-dependent hybridisation process and interface charge transfer mechanisms are highly required. Here, we perform a comprehensive study to elucidate the fundamental process during the reduced graphene oxide (rGO) and carbon nanotube (CNT) hybridisation, which enabled the fabrication of a rational-designed rGO/CNT hybrid aerogel (GCA) with a record energy storage performance beyond previously reported works. Based on spectroscopy and microscopy analysis, we found the hydrophilic and hydrophobic transition of GO which eliminates the surface-functionalised oxygen-containing moieties, is the origin of the π-π stacking hybridisation between rGO and CNTs. Moreover, we found the different amount of CNTs ‘solder’ in-between rGO sheets can offer GCA distinct mechanical elasticity, ion diffusion resistance and specific capacitance. As illustrated in the electrochemical impedance spectroscopy (EIS) and charge/discharge analysis, we found GCA 2-2 (rGO:CNT=2:2) display the best gravimetric capacitance of 117 F∙g-1 at a discharge current density of 1 A∙g-1, which help us to fabricate an ultra-flyweight supercapacitor with a large energy density of 3.53 Wh∙kg-1 at a power density of 283.4 W∙kg-1.

A WebGIS Solution for Estimation Landuse Affected by Salinity Intrusion: Case Study in Ben Tre Province, Vietnam

Ben Tre, located in the Mekong Delta, is one of the most places affected by climate change, especially in sea level rise and salinity intrusion. For the seven provinces bordering the East Sea, the need for monitoring water resources is critical. This paper represents an approach to build a web-based GIS to store, manage, analyze and visualize the data of saline intrusion phenomenon. The novelty focuses on automating the workflow for the generation and publication of time series saline intrusion maps on server side. The analysis results are provided on the web browser interface. This helps users access valuable information without having to install professional GIS software. Spatial distribution of saline intrusion and statistical results support government agencies in planning and decision making. This work is funded by Ben Tre Provincial People's Committee and Vietnam Academy of Science and Technology (VAST).
Vanishing Cantilever Calibration Error with Magic Ratio Atomic Force Microscopy

An analysis is presented of the error propagation through a simplified contact model for atomic force microscopy (AFM) static force spectroscopy, one that is meant to be intuitive and pedagogically informative rather than maximally realistic. It is shown that an important dimensionless ratio appears in several critical locations in the closed form error equation, and that under common calibration methods there exists a ``magic'' ratio where an important class of systematic calibration errors cancel out completely. This argument is extended to more complex contact models and the presence of a magic ratio is demonstrated using real data. A method is shown to identify and operate at optimal conditions in commercial AFMs. Targeting this magic ratio provides a simple, comprehensive guideline for cantilever selection, system calibration, and imaging parameter selection.
Comparative urbanization of birds in China and Europe based on birds associated with trees

Abstract Urbanization effects on living organisms are spatially heterogeneous. Here we quantified the abundance of birds per tree in forested urban and rural habitats for 85,829 trees mainly in China and Europe. A population model was based on the assumption that: 1) birds have a normally distributed habitat preference; 2) an increase in population size linked to the habitat preference; 3) a population size dependent on the habitat preference; and 4) the removal of a certain fraction of individuals giving rise to extinction. We tested for large-scale differences in the impact of urbanization on the frequency distribution of the difference in abundance between urban and rural habitats in China and parts of Europe. The difference in the frequency distribution of urban population density of birds in trees minus rural population density of birds in trees in China and Europe was statistically significant, suggesting that the abundance of birds differed between trees in urban and rural habitats, but more so in China than in Europe. We hypothesize that more pronounced differences in China than in Europe may have arisen due to the Four Pests Campaign in 1958–1962 that resulted in death of hundreds of millions of birds (mainly tree sparrows Passer montanus, but also numerous other less common species that were starting to become urbanized around 1960). Species that were less common in 1960 could not sustain reductions in population size in urban areas and hence these species are still rare or absent in urban areas today 60 years later.
‘Entering the world of academia is like starting a new life’: a trio of reflections from Health Professionals joining academia as second career academics

ABSTRACT This research explored the experiences of three health professionals transitioning into academia as second-career academics (SCAs), with the aim of gaining insight into potential enablements and constraints for such career changers. The process of redefining identity from expert health professional to novice academic could occur through a three-stage process of transitioning. However, if SCAs experience an unsupportive or ‘care-less’ environment, such redefining may not occur. The paper attempts to illuminate the crucial role of educational developers in understanding and supporting SCAs when they ‘start a new life’ in academia.
Parasites, Paleoclimate, and the Peopling of the Americas

Paleoparasitological findings and paleoclimate modelling simulations indicate that early peoples migrating via the Clovis first route across Beringia into North America could not have traversed the required distance in time to provide a reasonable explanation for the presence of the hookworm in the preColumbian Americas. The introduction of the hookworm into the Americas by a land migration at around 13,000 years BP could have happened only under extraordinary circumstances and even then would have required displacement rates that appear to have no parallel in the archaeology of the continent. This implies that while the Clovis people may have been the first migrants to the Americas, they were almost certainly not the only such migrants.

Objectives: To determine normative vestibular-ocular-reflex (VOR) gain values for the vertical semicircular canals (SCCs) within a Danish cohort of healthy adults. Normative data regarding the vertical SCCs are sparse. Assessing the function of all 6 SCCs is important, as some vestibular diseases may selectively affect specific SCCs. Methods: A prospective cross-sectional study of 60 subjects aged 18–65 years with no previous vestibular disorders. All subjects underwent complete examination of all 6 SCCs with EyeSeeCam video head impulse test (vHIT) system. Results: Mean VOR gain values of the right anterior and left posterior canal were 1.46 and 1.43 respectively. For the left anterior and right posterior canals, mean VOR gain values were 0.96 and 0.97 respectively. Conclusions: Our results suggest that mean VOR gain is close to 1.4 in the right anterior and left posterior plane and close to one for the left anterior and right posterior plane when testing the vertical SCCs in healthy adults with the EyeSeeCam vHIT system.

Bayesian analysis of the Box-Cox transformation model based on left-truncated and right-censored data

In this paper, we discuss the inference problem about the Box-Cox transformation model when one faces left-truncated and right-censored data, which often occur in studies, for example, involving the cross-sectional sampling scheme. It is well-known that the Box-Cox transformation model includes many commonly used models as special cases such as the proportional hazards model and the additive hazards model. For inference, a Bayesian estimation approach is proposed and in the method, the piecewise function is used to approximate the baseline hazards function. Also the conditional marginal prior, whose marginal part is free of any constraints, is employed to deal with many computational challenges caused by the constraints on the parameters, and a MCMC sampling procedure is developed. A simulation study is conducted to assess the finite sample performance of the proposed method and indicates that it works well for practical situations. We apply the approach to a set of data arising from a retirement center.
An Asymmetric Effect of Economic Growth, Foreign Direct Investment and Financial Development on the Quality of Environment in Nigeria

Environmental degradation is anticipated to cause a loss of 6 percent to 30 percent of GDP in Nigeria by the year 2050, converting to US$ 100 billion to US$ 460 billion also Nigeria may face the risk of temperature increase between 2.5°c and 4.5°c by the year 2100 in the absence of mitigation action. As such the study aims at investigating the asymmetric impact of macroeconomic variables on quality of environment in Nigeria. The analysis incorporates data from the annual time series covering the 1970-2018 periods and applies the non-linear ARDL method for the empirical analysis. The findings show that negative and positive GDP escalates the quantity of carbon emissions, thereby worsening environmental sustainability. Through positive as well as negative shocks, FD leads to carbon emissions and FDI increases carbon emissions through positive shocks and decreases them by negative shocks. The positive shock from the FDI increases the CO2 emissions in Nigeria, resulting in environmental degradation. The research suggests implementing technology to promote the productive use of resources that would help boost environmental efficiency, increase long-run productivity and save energy. The lenders will ease financing for the energy sector and devote financial resources to ecologically friendly companies, rather than investing them in financing customers. FDI inflows should be tracked to curb CO2 emissions.
