Reconstructing Missing Hourly Real-Time Precipitation Data Using a Novel Intermittent Sliding Window Period Technique for Automatic Weather Station Data

引用

Journal of Meteorological Research 2017年第4期31卷 774-790页

作者： Nagaraja HEMA krishna KANT Department of Computer Science and Engineering/Information Technology Jaypee Institute of Information Technology Noida 201307 India

Precipitation is the most discontinuous atmospheric parameter because of its temporal and spatial variability. Precipitation observations at automatic weather stations（AWSs） show different patterns over different time periods. This paper aims to reconstruct missing data by finding the time periods when precipitation patterns are similar, with a method called the intermittent sliding window period（ISWP） technique—a novel approach to reconstructing the majority of non-continuous missing real-time precipitation data. The ISWP technique is applied to a 1-yr precipitation dataset（January 2015 to January 2016）, with a temporal resolution of 1 h, collected at 11 AWSs run by the Indian Meteorological Department in the capital region of Delhi. The acquired dataset has missing precipitation data amounting to 13.66%, of which 90.6% are reconstructed successfully. Furthermore, some traditional estimation algorithms are applied to the reconstructed dataset to estimate the remaining missing values on an hourly basis. The results show that the interpolation of the reconstructed dataset using the ISWP technique exhibits high quality compared with interpolation of the raw dataset. By adopting the ISWP technique, the root-mean-square errors（RMSEs）in the estimation of missing rainfall data—based on the arithmetic mean, multiple linear regression, linear regression,and moving average methods—are reduced by 4.2%, 55.47%, 19.44%, and 9.64%, respectively. However, adopting the ISWP technique with the inverse distance weighted method increases the RMSE by 0.07%, due to the fact that the reconstructed data add a more diverse relation to its neighboring AWSs.

Fabrication and Characterisation of Rutile-TiO_2 Coatings on Metallic Alloy Substrates

引用

材料热处理学报 2004年第5B期25卷 862-865页

作者： D. Siva Rama krishna School of Materials Engineering Nanyang Technological University Singapore 639798

In the present work, attempts have been made to extend the use of the tribological and chemical properties of rutile-TiO2 to metallic alloy systems, by forming a rutile coating on the metallic substrates. Two metallic alloys were selected in this study, including AISI316L austenitic stainless steel and aluminium alloy. The rutile-based coatings were fabricated by magnetron sputter deposition of a pure titanium coating first, and then thermal oxidation of the coated specimens to partially convert the titanium coating to rutile oxide and to promote interfacial reactions which can significantly enhance the coating-substrate adhesion strength. The structures and properties of the coating-substrate systems were characterized by a variety of analytical and experimental techniques, including X-ray diffraction, glow discharge spectrometry, high resolution SEM, nanoindentation, microscratch, friction and wear testing, as well as electrochemical testing. The results show that the friction and wear properties, as well as the corrosion resistance of the metallic alloys can be significant enhanced by surface engineering with rutile-TiO2.

ROLE OF HARVESTING IN CONTROLLING CHAOTIC DYNAMICS IN THE PREDATOR-PREY MODEL WITH DISEASE IN THE PREDATOR

引用

International Journal of Biomathematics 2013年第2期6卷 105-129页

作者： krishna PADA DAS Department of Mathematics Mahadevananda Mahavidyalaya Monirampore P. O. Barraekpore Kolkata 700120 India

Predator prey model with harvesting is well studied. The role of disease in such system has a great importance and cannot be ignored. In this study we have considered a predator prey model with disease circulating in the predator population only and we have also considered harvesting in the prey and in the susceptible predator. We have studied the local stability, Hopf bifurcation of the model system around the equilibria. We have derived the ecological and the disease basic reproduction numbers and we have observed its importance in the community structure of the model system and in controlling disease propagation in the predator population. We have paid attention to chaotic dynamics for increasing the force of infection in the predator. Chaotic population dynamics can exhibit irregular fluctuations and violent oscillations with extremely small or large population abundances. In this study main objective is to show the role of harvesting in controlling chaotic dynamics. It is observed that reasonable harvesting on the prey and the susceptible predator prevents chaotic dynamics.

Alternative food and external source of infection stabilize predator-prey oscillations -- A conclusion drawn from an eco-epidemiological model

引用

International Journal of Biomathematics 2015年第3期8卷 83-107页

作者： krishna Pada Das Department of MathematicsMahadevananda Mahavidyalaya Barrackpore Kol- 120 India

Das et al. [Effect of disease-selective predation on prey infected by contact and external sources, Biosystems 95（3）（2009） 188-199] proposed an eco-epidemiological model where the prey species is infected through the external source of infection and contact of the species. In this present study we have modified their model by assuming that the predator consumes both the susceptible as well as the infected prey following the modified Holling type-Ⅱ functional response. Our main focusing points of this study are the role of infection rate （both internal and external）, alternative food, and half-saturation constant in the predator prey dynamics with disease in the prey population. We have shown the local stability of the boundary as well as the interior equilibrium point under certain conditions. We have Mso worked out the permanence of the system. Our simulation results show that the system enters into limit cycle oscillations from stable position for higher values of the contact rate. But it is also shown that the external infection rate, enrichment of the alternative food of the predator population and the half-saturation constant can prevent limit cycle oscillations and stabilize the system. Thus external dis- ease propagation, enrichment of the alternative food resource, and the half-saturation constant are the key factors for preventing the oscillatory behavior of the species.

Upwelling favourable winds along the Indian coasts were studied using a highresolution(9 km grid)atmospheric mesoscale model(MM5)reanalysis from 1 to 5 June 2006,off the west coast of India and from 5 to 10 December 2005,off the east coast of *** winds are verified with satellite winds at two *** wind hind-casts from the above periods reveal narrow bands(about 10×50 km)of strong winds to the coast and adjacent to the major coastal *** bands,which are sub-grid scale in operational models,were capable of generating local upwelling greater than 10 m/*** the mean and spatial components of the model alongshore wind increase by a factor of 3 to 4 from the south to the north along the west coast,and by a factor of 2 to 3 from the north to the south along the east coast of *** field increases will drive enhanced ocean upwelling along the west coast of India,and the new hypothesis suggests that the variations in local wind may contribute to the coastal upwelling in this region.
