Information on urban vegetation and land use is critical for sustainable environmental management in cities. In general, urban vegetation is important for urban planning because it helps to maintain a balance between the natural environment and the built-up region. The assessment of the composition and configuration of the vegetation is important to highlight the urban ecosystem. Thus, obtaining information about urban vegetation is critical for developing a sustainable urban development strategy. Remote sensing is increasingly being used to generate such data for mapping and monitoring changes in urban vegetation. The aim of this study is to identify and classify vegetation using the high-resolution Pleiades satellite image in urban park areas using pixel-based image analysis. Pixel based method was applied and support vector machine algorithm was used for classification of urban vegetation. Comparison of accuracy was made from the error matrices, overall accuracy and kappa coefficient for vegetation and non-vegetation classes. The overall accuracy for the classification approach was 98.98% and a kappa value of 0.97. The result demonstrates the ability of high-resolution imagery to accurately extract urban vegetation despite the complex surface of the urban area. The findings can be used to support other research and applications related to urban green space monitoring, conservation, and future urban vegetation planning.

An autonomous robot, also known as simply an autorobot or autobot, is a robot that performs behaviors or tasks with a high degree of autonomy. Autonomous robotics is usually considered to be a subfield of artificial intelligence, robotics, and information engineering. Specifically, “autonomous robots can help: Increase efficiency and productivity. Reduce error, re-work, and risk rates. Improve safety for employees in high-risk work”environments. In this COVID era every 4 out of the 5 Fortune 500 e-commerce companies and especially the e-commerce giants like Walmart , Amazon and Flipkart are focusing even more on contact less delivery. Delivery using automated bots is a concept that can be used even after the Covid situation gets over. The popularity of e-commerce buying is exploding, and the phenomenon has huge implications for shippers and distributors. To paraphrase Charles Darwin, “those companies best prepared to adapt to this new reality are the ones that will flourish while laggards will be left in the dust”. “Logistics is all about movement from one place to another. This movement happens across facilities and within facilities. While AGVs (AUTOMATED GUIDED VEHICLES) have found their way into applications of material movement inside a warehouse, they are designed to move across flat surfaces with minor undulations (in some cases requiring specialised mezzanine surfaces). This paper comes up with conceptual building and designing an autonomous robot which can work on flat surfaces and even climb up and down standard stairs with a payload of 3-5kg. This paper further will inform you about the conceptual building of an autonomous stair climbing robot involving all the steps like sensor fusion , navigation , tracking , mapping and path planning.

In the developing countries accident is the major cause of death. “Speed Kills”, but still people don’t care enough to act safe while driving on road. Road traffic accidents and deaths caused by them are most critical issues now days. It is also impacting the country’s economy. According to Million Death Study (MDS) about 2.3 million people die in India per year. In that 137 thousand is because of road accidents. That is about 377 people per day. In that 3.7% because of failed to look the road. We can see that many of them are curve roads. In the mountain roads there will be tight curves and the roads will be narrow. In these kinds of situations the driver of a vehicle cannot see vehicles coming from opposite side on the roads. Thousands of people lose their lives each year because of this problem. Since we are talking about mountain roads here other side might lead to a cliff and heavy bends. The solution for this problem is alerting the driver about the vehicles coming from opposite side in Ghats sections. This is done by keeping an ULTRASONIC SENSOR on one side of the road before the curve and keeping a LED light after the curve, so that if a vehicle comes from one end of the curve, sensor senses and LED light glows at the opposite side. By looking at the LED light on/off criteria driver can be alert and can slow down the speed of the vehicle.

Murga y minstrel a inicios del siglo XX en Valparaíso y otros puertos poscoloniales: estereotipos de negritud en agrupaciones cómicas y carnavalescas
Authors: Gana Núñez Alejandro
Published: July 2021

Intentando comprender la presencia de una compañía de músicos blancos representando negros en Viña del Mar en 1911, este artículo aborda el uso genérico de la palabra murga, para una agrupación que presenta elementos estéticos y escénicos propios del minstrel americano. Este vínculo nos permite reflexionar sobre cómo la comicidad en el carnaval, en el teatro y en los medios de comunicación, utilizó significados sobre la propia identidad blanca frente a un otro negro o mestizo, risible o ridículo. El contrapunto con expresiones musicales y escénicas en puertos como Ciudad del Cabo y Buenos Aires, nos permite también contrastar la influencia del blackface en otros territorios, y en cómo esas sociedades enfrentaron las desigualdades raciales mediante la comicidad y lo festivo.

Fighting Covid-19 Pandemic: Analysis of the Swedish Model vs. Lockdown Model
Authors: Fatema Turkistani  , Aseel Bin Sawad
Published: July 2021

Many countries resorted to the lockdown model that includes shutting down all non-essential activities to avoid the spread of COVID-19. Comparatively, Sweden applied the herd immunity model. The aim of this study is to analyze the Swedish model compared to the lockdown model based in other countries to understand the impact of these models on public health, health economics and overall economy of the respective countries. Based on the findings, the paper aims to shed light on which model proves to be more effective to cope with the pandemic and provide recommendations for other countries to follow accordingly. Our methodology was a narrative review that synthesizes current literature obtained from searches on various databases, authoritative texts, and hand searches. While it is too early to determine the long term effects of both models, it seems  that  Sweden’s  herd  immunity  model  is more  effective  considering  aspects  of  overall  public  health,  health  economic factors, and the overall economy. The major cons of the Swedish model was a failure in controlling infection spread in elderly nursing homes, as half the death toll comprises individuals belonging to this community. While Sweden was able to soften the effect of COVID-19  impact  on  its economy  without  a lockdown,  the manufacturing  industry  was impacted  due  to lack of availability of required parts to be supplied by other countries. Thus from our review , we found that Herd-immunity model is more effective, but it depends on other factors of the country such as population density, as it is not plausible for countries such as Spain, the US or Germany, which need to expose high numbers of people to COVID-19 to attain herd immunity.

The six institutions in this linkage position, must be coordinated through effective management, because in addition to affecting the success of the program, feedback can also hinder the development of cocoa production. One of the institutions in the linkage position, namely private companies occupies a key priority position in the development of cocoa production.
The effects of corporate venture capital on value creation and innovation of European public owned firms
Authors: Bider Giacomo , Gigante Gimede
Published: July 2021

The practice of corporate venture capital (CVC) has been widely adopted by corporations that invest in highly disruptive start-ups with the aim of fueling innovation and gain strategic advantages. Even if a wide consensus exists on the strategic benefits and performance of CVC investors in the North American venture capital industry, scarce information is available on the European CVC ecosystem. Therefore, the scope of this research is to investigate whether CVC activity, measured as the number of investments, deal size, and the number of realized exits is beneficial for value creation and innovation for European listed companies. Using a panel of CVC investors linked to European listed firms, it is found evidence that CVC activity creates firm value in the period under consideration (2008–2019), confirming North American’s past evidence. Surprisingly, exits convey a negative effect on firm value, suggesting that CVC performance may not be satisfactory enough. Moreover, when considering innovation, evidence is presented that investing in rounds with a higher deal size positively affects investor’s patenting levels, indicating that the later the start-up’s stage in its life cycle, the higher the possibility for the CVC investor to effectively absorb its technology. The relationship is true also for lagged CVC activity, confirming deferred effects on innovation demonstrated on US companies. The findings shed light on the European CVC ecosystem and give room for additional research on CVC investors’ exit performance and co-investors’ benefits on patenting levels

Appendix adenocarcinoma associated with ulcerative colitis (UC) is
extremely rare. Pathological examination of a man with 6-year history of
UC revealed a primary appendix adenocarcinoma mixed with adenoma
component. Dysplasia was not identified. The adenoma-carcinoma sequence,
but not the dysplasia-carcinoma sequence, might be involved in this
UC-associated appendix adenocarcinoma.
Evaluation of the Impacts of Climate Change on Runoff in Dadu River Basin Based on CORDEX Regional Climate Model

Published: July 2021

Owing to the rich water resources, the Dadu River basin is an important
hydroelectric resources development area in Sichuan Province over China.
The climate change will have a great impact on the runoff change in the
Dadu River Basin. The prediction of the future runoff in the Dadu River
Basin can effectively improve the utilization rate of water resources,
and provide a reference for hydropower dispatching. At first, to reduce
the uncertainties from climate model, this paper used Stepwise
Clustering Analysis to calibrate and validate the CORDEX regional
climate model ensemble data from 1970 to 2005 and projected the climate
change trend of Dadu River basin from 2035 to 2065. Then the Dadu River
watershed scales of SWAT model was established, using the SWAT-CUP for
calibration and verification. Finally, the corrected future climate data
are used to drive the SWAT model to realize the future runoff forecast
in the Dadu River Basin. The results show that under the scenario of
RCP4.5 and RCP8.5, the variation range of rainfall is small, and the
maximum and minimum temperatures show an overall increasing trend. The
maximum (minimum) temperature will increase about 0.6℃ (1.0℃) under the
scenarios of RCP4.5 and 0.9℃ (1.4℃) under the scenario of RCP8.5.
Compared with the baseline period, the future (2035-2065) annual runoff
under RCP4.5 and RCP8.5 scenarios will increase by about 8.6% and
8.2%, respectively. Under the future climate change, the inter-annual
runoff in the Dadu River Basin will change greatly, and the trend of
runoff fluctuation is not consistent before and after 2050. Before 2050,
runoff changes are small, however, after 2050, runoff changes under the
two scenarios will increase by about 12%. On the one hand, this trend
may be due to the impact of iceberg melting on runoff caused by
temperature changes around 2050, on the other hand, it may be due to the
combined effect of local plant evapotranspiration and ecological
regulation.

Published: July 2021

The primary approach to realizing long-term runoff prediction involves
combining a hydrological model with general circulation model. Previous
studies on the Source area of the Yellow River were all based on the
Coupled Model Intercomparison Project Phase 5 (CMIP5) data sets with
defects in physical mechanisms. In this paper, the Beijing Climate
Center Climate System Model (BCC-CSM2-MR) of CMIP6, which proved to
perform well in arid and semi-arid regions, will be used to drive the
Soil & Water Assessment Tool (SWAT) model and evaluate its
applicability in runoff simulation at Tang Nahai Hydrological Station
from 2011 to 2019. The occurrence of the extreme value of runoff, its
change trend, and the year of abrupt change of runoff in the four Shared
Socio-economic Pathway (SSP) scenarios (SSP1-2.6, 2-4.5, 3-7.0, and
5-8.5) during 2021-2100 were analyzed. The results show that: (1) the
runoff simulation evaluation index of SWAT driven by BCC-CSM2-MR in the
research area from 2011 to 2019 is excellent, and the runoff simulation
in the future is reliable and effective. (2) only the average annual
runoff in scenario 5-8.5 (708.5m /s) from 2021 to 2100 was significantly
higher than that in 2011-2019. Other scenarios are close to or less than
the annual runoff observed. Most importantly, the maximum and minimum
annual runoff values under the four scenarios all occurred during
2060-2080, so the attribution analysis of runoff extremum during
2060-2080 is worth further study. (3) it is necessary to evaluate
whether the existing reservoirs and hydropower stations in the Yellow
River basin can reasonably regulate and utilize the annual runoff under
scenario 5-8.5.
Design of Detection-Jamming Shared Waveform Based on Virtual Force Field Algorithm
Authors: Xiong GuoMiao , Li Yunpeng , Chen Chao
Published: July 2021

Due to the technical barriers between radars and jammers and the poor
performance of the traditional detection-jamming shared signal in
integrated radar-electronic warfare systems, a new detection-jamming
shared signal waveform based on the virtual force field algorithm (VFFA)
is proposed in this paper. First, a multi-objective and
multi-dimensional characteristic parameter optimization model, based on
a virtual force field, is established, and then the design principle of
the shared signal is presented in detail. The simulation results show
that the detection-jamming shared signal based on the VFFA presents the
deceptive jamming of multiple false targets in non-collaborative radar.
Further, there is better detection performance with the advantages of
multiple pulse repetition frequency (PRF) and pulse accumulation number,
which are highly sensitive to the multi-jagged PRF signals emitted by
the non-collaborative radar. According to the VFFA described in this
paper, the optimum detection-jamming shared signal waveform can be
output in real time for specific free space targets, to improve the
efficiency of integrated radar and electronic warfare systems.

Authors: Chang Huan-huan , An Lu , Dang Panhong , Luo Juan , Wang Jie
Published: July 2021

Objective: To investigate the appropriate drug therapy based on a novel
classification system for adenoids based on their appearance. Methods:
We used fiberoptic nasal endoscopy to determine the degree and
appearance of adenoid hypertrophy (AH). The adenoids were divided into
three types: edematous type, common type, and fibrous type. In adenoid
tissues, the eosinophils were counted. Immunohistochemistry and western
blot were done to determine the expression of CysLTR1, CysLTR2, CGR-α,
and CGR-β in different types of adenoids. Results: 70.67% (106/150) AH
patients with AR, and of them 68% (72/106) of adenoids were the
edematous type. The expression of CGR-α and CGR-β and eosinophil count
were higher in the edematous type but not in common and fibrous types.
The expression of the leukotriene receptor was stable in all types.
There was a positive correlation between eosinophil count in the blood
and in the adenoid tissue. Conclusion: AR was the risk factor for the
development of AH. Leukotriene receptor antagonist was an important drug
for the treatment of AH. The glucocorticoid was only useful in the
edematous type. Therefore, for AH patients with AR, patients with
edematous type adenoids and/or patients with increased eosinophils in
blood routine choose nasal glucocorticoid combined with leukotriene
receptor antagonist is appropriate. On the contrary, leukotriene
receptor antagonists alone can be selected to treat AH.
