1A review:On path planning strategies for navigation of mobile robot显示文摘This paper presents the rigorous study of mobile robot navigation techniques used so far.The step by step investigations of classical and reactive approaches are made here to understand the development of path planning strategies in various environmental conditions and to identify research gap.The classical approaches such as cell decomposition(CD),roadmap approach(RA),artificial potential field(APF);reactive approaches such as genetic algorithm(GA),fuzzy logic(FL),neural network(NN),firefly algorithm(FA),particle swarm optimization(PSO),ant colony optimization(ACO),bacterial foraging optimization(BFO),artificial bee colony(ABC),cuckoo search(CS),shuffled frog leaping algorithm(SFLA)and other miscellaneous algorithms(OMA)are considered for study.The navigation over static and dynamic condition is analyzed(for single and multiple robot systems)and it has been observed that the reactive approaches are more robust and perform well in all terrain when compared to classical approaches.It is also observed that the reactive approaches are used to improve the performance of the classical approaches as a hybrid algorithm.Hence,reactive approaches are more popular and widely used for path planning of mobile robot.The paper concludes with tabular data and charts comparing the frequency of individual navigational strategies which can be used for specific application in robotics.B.K.

2Path planning in uncertain environment by using firefly algorithm显示文摘Autonomous mobile robot navigation is one of the most emerging areas of research by using swarm intelligence. Path planning and obstacle avoidance are most researched current topics like navigational challenges for mobile robot. The paper presents application and implementation of Firefly Algorithm(FA)for Mobile Robot Navigation(MRN) in uncertain environment. The uncertainty is defined over the changing environmental condition from static to dynamic. The attraction of one firefly towards the other firefly due to variation of their brightness is the key concept of the proposed study. The proposed controller efficiently explores the environment and improves the global search in less number of iterations and hence it can be easily implemented for real time obstacle avoidance especially for dynamic environment. It solves the challenges of navigation, minimizes the computational calculations, and avoids random moving of fireflies. The performance of proposed controller is better in terms of path optimality when compared to other intelligent navigational approaches.B.K.Patle Anish Pandey A.Jagadeesh D.R.Parhi 2018Defence Technology(防务技术)2018,14,6:14
3Optimum path planning of mobile robot in unknown static and dynamic environments using Fuzzy-Wind Driven Optimization algorithm显示文摘This article introduces a singleton type-1 fuzzy logic system(T1-SFLS) controller and Fuzzy-WDO hybrid for the autonomous mobile robot navigation and collision avoidance in an unknown static and dynamic environment. The WDO(Wind Driven Optimization) algorithm is used to optimize and tune the input/output membership function parameters of the fuzzy controller. The WDO algorithm is working based on the atmospheric motion of infinitesimal small air parcels navigates over an N-dimensional search domain. The performance of this proposed technique has compared through many computer simulations and real-time experiments by using Khepera-Ⅲ mobile robot. As compared to the T1-SFLS controller the Fuzzy-WDO algorithm is found good agreement for mobile robot navigation.Anish Pandey Dayal R.Parhi 2017Defence Technology(防务技术)2017,13,1:12
4董事激励与公司业绩——实验的证据显示文摘我们在实验框架下检验了董事会成员的激励对股东财富和CEO报酬的影响,以及该报酬与公司业绩之间的敏感度.文中提出了两种任命董事的方法,一种由CEO任命,另一种由最大的股东自动担任董事.由董事会决定CEO的报酬,而CEO负责企业的生产、投资和分红决策.投资者根据接收到的每个公司的分红、资本收益这些信息,通过买卖这些企业的股票来调整他们的资产组合. 我们发现,薪酬与业绩之间的敏感度随董事持股比例的增加而上升.此外,当大股东作为董事会成员时,经济体所产生的财富(股东财富是其中的一部分)更大;而当CEO选择董事时,结果是缺乏效率的.本文讨论了关于董事职能和相关代理成本这一研究结果,以及标准会计框架下,限制执行人员报酬和报表标准化要求.Anish Shah Shyam Sunder 2004南开管理评论2004,7,4:10
5In vivo antioxidant and hepatoprotective activity of methanolic extracts of Daucus carota seeds in experimental animals显示文摘Objective:To assess the In vivo anlioxid Fanl and hepaloproleclive activity of metlianolic exlracl of Daucus carota(D.carota) seeds in experimental animals.Methods:Methanolic extracts of D.carota seeds is used for hepatoproleclion assessment.Oxidative stress were induced in rats by thioacetamide 100 nig/kg s.c.in four groups of rats(two test,standard and toxic control). Two test groups received D.carota seeds extract[DCSE) at doses of 200 mg/kg and 400 mg/kg. Standard group received silymarin(25 mg/kg) and toxic control received only thioacetamide. Control group received only vehicle.On the 8th day animals were sacrificed and liver enzyme like serum glutamic pyruvic transaminase(SGPT),serum glutamic-oxaloacetic transaminase(SCOT) and alkaline phosphatase(ALP)were estimated in blood serum and antioxidant enzyme like superoxide disnuituse(SOD),cululase(CAT),glutathione reductase(CKD),glutathione peroxidase(GPX),glutalhione-S-transferase(GST)and lipid peroxidation(LPO)were estimated in liver homogcnatc.Results:A significant decrease in SGPT,SCOT and ALP levels was observed in all drug treated groups as compared to thioacetamide group(P<0.001) and in case of antioxidant enzyme a significant(P<0.001) increase in SOD.CAT,GRD,GPX and GST was observed in all dmg treated groups as compared with thioacetamide group.But in case of LPO a significant(P <0.001) reduction was observed as compared to toxic control group.Conclusions:DCSE has contributed lo the reduction of oxidative stress and the protection of liver in experimental rals.Kamlesh Singh Nisha Singh Anish Chandy Ashish Manigauha 2012Asian Pacific Journal of Tropical Biomedicine2012,2,5:6
6A new type of blockchain for secure message exchange in VANET显示文摘In the Vehicular Ad-hoc NETworks(VANET),the collection and dissemination of life-threatening traffic event information by vehicles are of utmost importance.However,traditional VANETs face several security issues.We propose a new type of blockchain to resolve critical message dissemination issues in the VANET.We create a local blockchain for real-world event message exchange among vehicles within the boundary of a country,which is a new type of blockchain suitable for the VANET.We present a public blockchain that stores the node trustworthiness and message trustworthiness in a distributed ledger that is appropriate for secure message dissemination.Rakesh Shrestha Rojeena Bajracharya Anish P.Shrestha Seung Yeob Nam 2020Digital Communications and Networks2020,6,2:6
7Climatic periodicities recorded in lake sediment magnetic susceptibility data:Further evidence for solar forcing on Indian summer monsoon显示文摘The Indian summer monsoon exhibits considerable spatio-temporal variability.It is therefore important to understand its dynamics and the inherent periodicities.In this study,we have performed spectral and wavelet analyses of magnetic susceptibility data for sediments from Thimmannanayakanakere(TK)-a small lake in southern India.The main objective of this investigation is to identify and explain the possible origin of the prominent periodicities present in the magnetic susceptibility data.Significant periodicities in the TK χ_(lf)data are centered at 906,232,147,128,96,61,54 and 44 years,which might have a solar origin.The wavelet power spectrum of the raw and detrended χ_(lf)data confirms the findings of spectral analysis and also provides temporal variations of the significant cyclicities during the past3700 cal.years B.P.Positive correlation is documented between sunspot activity and TK xif data;crossspectral analysis of the reconstructed sunspot data and TK xif data suggest that there is a strong coherence between the two datasets as significant periodicities are documented in both.There is a good match between the TK xif and the reconstructed total solar irradiance data for the past 1200 years.However,an out-of-phase relationship is documented at certain time-intervals,which may be attributed to uncertainties in the age-depth model.The results obtained from this study show that solar variations are the main controlling factor of the southwest monsoon and,like other archives from different regions in India,the TK lake sediments have also recorded these solar signatures.Anish Kumar Warrier Kizhur Sandeep Rajasekharaiah Shankar 2017Geoscience Frontiers2017,8,6:3
8Early debridement and delayed primary vascularized cover in forearm electrical burns: A prospective study显示文摘AIM To look into the management options of early debridement of the wound, followed by vascularized cover to bring in fresh blood supply to remaining tissue in electrical burns. METHODS A total of 16 consecutive patients sustaining full thickness forearm burns over a period of one year were included in the study group. Debridement was undertaken within 48 h in 13 patients. Three patients were taken for debridement after 48 h. Debridement was repeated within 2-4 d after daily wound assessment and need for further debridement. RESULTS On an average two debridements(range 1-4) was required in our patients for the wound to be ready for definitive cover. Interval between each debridement ranged from 2-18 d. Fourteen patients were provided vascularized cover after final debridement(6 free flaps, 8 pedicled flaps). Functional assessment of gross hand function done at 6 wk, 2 mo, 3 mo and 6 mo follow-up. CONCLUSION High-tension electrical burns lead to significant morbi-dity. These injuries are best managed by early decompression followed by multiple serial debridements. The ideal timing of free flap coverage needs further investigation.Aniruddh Mene Gautam Biswas Atul Parashar Anish Bhattacharya 2016World Journal of Critical Care Medicine2016,5,4:2

19Solving Markov Decision Processes with Downside Risk Adjustment显示文摘Markov decision processes(MDPs) and their variants are widely studied in the theory of controls for stochastic discreteevent systems driven by Markov chains.Much of the literature focusses on the risk-neutral criterion in which the expected rewards,either average or discounted,are maximized.There exists some literature on MDPs that takes risks into account.Much of this addresses the exponential utility(EU) function and mechanisms to penalize different forms of variance of the rewards.EU functions have some numerical deficiencies,while variance measures variability both above and below the mean rewards;the variability above mean rewards is usually beneficial and should not be penalized/avoided.As such,risk metrics that account for pre-specified targets(thresholds) for rewards have been considered in the literature,where the goal is to penalize the risks of revenues falling below those targets.Existing work on MDPs that takes targets into account seeks to minimize risks of this nature.Minimizing risks can lead to poor solutions where the risk is zero or near zero,but the average rewards are also rather low.In this paper,hence,we study a risk-averse criterion,in particular the so-called downside risk,which equals the probability of the revenues falling below a given target,where,in contrast to minimizing such risks,we only reduce this risk at the cost of slightly lowered average rewards.A solution where the risk is low and the average reward is quite high,although not at its maximum attainable value,is very attractive in practice.To be more specific,in our formulation,the objective function is the expected value of the rewards minus a scalar times the downside risk.In this setting,we analyze the infinite horizon MDP,the finite horizon MDP,and the infinite horizon semi-MDP(SMDP).We develop dynamic programming and reinforcement learning algorithms for the finite and infinite horizon.The algorithms are tested in numerical studies and show encouraging performance.Abhijit Gosavi Anish Parulekar 2016International Journal of Automation and computing2016,13,3:1
