        Quantile estimation using near optimal unbalanced ranked set sampling

        Nautiyal, Raman,Tiwari, Neeraj,Chandra, Girish The Korean Statistical Society 2021 Communications for statistical applications and me Vol.28 No.6

        Few studies are found in literature on estimation of population quantiles using the method of ranked set sampling (RSS). The optimal RSS strategy is to select observations with at most two fixed rank order statistics from different ranked sets. In this paper, a near optimal unbalanced RSS model for estimating p<sup>th</sup>(0 < p < 1) population quantile is proposed. Main advantage of this model is to use each rank order statistics and is distributionfree. The asymptotic relative efficiency (ARE) for balanced RSS, unbalanced optimal and proposed near-optimal methods are computed for different values of p. We also compared these AREs with respect to simple random sampling. The results show that proposed unbalanced RSS performs uniformly better than balanced RSS for all set sizes and is very close to the optimal RSS for large set sizes. For the practical utility, the near optimal unbalanced RSS is recommended for estimating the quantiles.

      • Evaluating and Certifying Component-Based Software Using Weighted Assignment Technique

        Lata Nautiyal,Preeti 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.1

        Certification refers to the verification of definite feature of an object, person, or an organization. This verification is often, but not always, provided by some form of external review, education, assessment, or audit. In general, the main certification idea is to bring quality process to a certain software product. One of the core goals to achieve quality in component based product is to acquire reliability, quality and compatibility with other components. We have proposed an evaluation process for certification of component-based software. Certification is performed at component as well as system level. The six factors given by ISO are used to certify the system or component. Some other factors are also taken into consideration for certification process. Unstructured weighting technique is used to assign weights to these seven factors.

      • Silane grafted chitosan for the efficient remediation of aquatic environment contaminated with arsenic(V)

        Lalhmunsiama,Lalchhingpuii,Nautiyal, B.P.,Tiwari, D.,Choi, S.I.,Kong, S.H.,Lee, S.M. Academic Press 2016 JOURNAL OF COLLOID AND INTERFACE SCIENCE - Vol.467 No.-

        Hypothesis: Chitosan, naturally abundant biomaterial showed an insignificant affinity toward arsenate. The incorporation of organosilane could improve the physical and chemical properties of chitosan for the efficient removal of arsenate from aquatic environment. Experiment: The hybrid materials were obtained by grafting the natural biopolymer chitosan with 3-mercaptopropyl trimethoxysilane (CHMS) and trimethoxy-octylsilane (CHTS). The hybrid materials along with bare chitosan were characterized with SEM-EDX, FT-IR and BET specific surface area analyses and the solid materials were further employed in the efficient remediation of aqueous solutions contaminated with As(V) under batch and column reactor operations. Findings: The hybrid materials showed an extremely high percentage of As(V) removal compared to bare chitosan within a wide range of pH. As(V) was aggregated rapidly onto the solid surfaces and relatively high percent removal of As(V) was achieved in a wide range of As(V) initial concentrations. Moreover, As(V) was bound with, relatively, weaker forces and forming an 'outer sphere complexes' at the surface of solids. The presence of co-existing ions could not significantly affect the removal of As(V) from aqueous solutions. Furthermore, breakthrough data confirmed that these two hybrid materials possessed significantly high loading capacity of As(V) even under dynamic conditions.

        Morphological and Molecular Characterization of Thamnocalamus falconeri Hook f. ex. Munro

        Tiwari, Chandrakant,Bakshi, Meena,Nautiyal, Subhash Institute of Forest Science 2015 Journal of Forest Science Vol.31 No.3

        The economy of India and so also of many Asian countries depends on bamboos and their uses are not only in domestic items but also in rural housing and raw materials to several industries and germplasm characterization is an important link between the conservation and utilization of plant genetic resources. Classical taxonomic studies of the bamboos are based on floral morphology and growth habit, which can cause problems in identification due to erratic flowering coupled with different biotic agencies and environmental factors. Identification and genetic relationships among accessions of Thamnocalamus falconeri were investigated using morphology and random amplified polymorphic DNAs (RAPD) technique. Analysis started by using 51 vegetative characters and forty two 10-mer primers that allowed us to distinguish different genotypes hailing from different eco- zones of Garhwal Himalayas (India). The selected primers (12) were used for identification and for establishing a profiling system to estimate genetic diversity. A total of 79.33% polymorphism was estimated by using 12 selected primers. The genetic similar analysis was conducted based on binary digits i.e. presence (1) or absence (0) of bands, which revealed a wide range of variability among the species whereas genetic relatedness was quite high based on vegetative characters. Cluster analysis clearly showed two major clusters for both of the markers viz. morphology and RAPD belonging to 10 accessions of T. falconeri. Two major clusters were further divided into minor clusters. Cluster based on RAPD marker showed grouping of accessions of closed locality whereas analogy was reported for vegetative traits. The RAPD technique has the potential for use in species identification and genetic relationships studies of bamboo for breeding program.

        Research Trend on Water Tank Automation

        Peng Cheng,Garima Nautiyal 사단법인 미래융합기술연구학회 2017 아시아태평양융합연구교류논문지 Vol.3 No.4

        his paper aims to present a new concept of automatic tank filling system. A typical household water tank uses a ball mechanism to control the filling of water in the tank. The process is not automatic as the motor used has to be operated manually. The automatic systems uses costly electronic sensors. The new concept which is being presented is without the use of any electronic component. The idea behind the water tank automation is that as soon the water level goes down at 10%, the motor automatically switches on and as soon the water level reaches to 90% of the total height, the motor automatically switches off. This process is controlled and automated using a programmable logic controller (PLC) through a ladder logic. Water tank automation will aid in an increased energy saving.

        Yield Gap Analysis of Mulberry Sericulture in Northwest India

        Bhatia, Narendra Kumar,Yousuf, Mohammad,Nautiyal, Raman Korean Society of Sericultural Science 2013 International Journal of Industrial Entomology Vol.27 No.1

        At the interface of reducing agricultural income and increasing unemployment in agrarian economy of rural India, this article summarizes and evaluates the state of mulberry sericulture in northwest India, which includes Himachal Pradesh, Punjab, Rajasthan, Uttarakhand, and Uttar Pradesh. In $11^{th}$ plan period (2007-2012), there was an addition of 6 196 ha (217.09 %) of mulberry acreage at annual linier growth rate of 33.44%. However, total silk production could increase only by 54.64 MT (78.57%) at annual linier growth rate of 15.59 %, due to 43.93% (10.82 kg/ha) reduction in silk productivity at negative growth rate of -13.46%, annually. And now, average raw silk productivity in north-western states of India remains at 13.81 kg/ha, which is lower by 452.93 % (76.36 kg) in comparison to the national average of 100.90 kg/ha. Paper summaries the reasons for increasing cocoon yield gap at farmer's level and discuss the ways and means to increase raw silk productivity to improve the livelihood delivery of mulberry sericulture in northwest India.
