Variograms and regression methods of their creation

The role of interpolation methods in creation of the Digital elevation models (DEM) is an actual problem from theoretical and application aspect. Geo-statistical interpolation methods respect autocorrelation of input data, which is expressed by variogram function. The aim of this paper is to describe creation of variogram model functions and estimation of their parameters and also implementation of variogram to software...

Association and inter-relationship among yield and yield contributing characters and screening against Cercospora leaf spot in mung bean (Vigna radiata L.)

Thirty-five genotypes of Mung bean (Vigna radiata L.) along with check Shalimar Mungbean-1 were evaluated to elicit information on association and interrelationship for yield and its component traits. Seed yield plant-1 showed positive significant association with number of clusters plant-1, number of primary branches plant-1, number of pods plant-1, number of seeds pod-1, pod length, and 100-Seed weight ,and ...

Slope of siltation of Dam No.7 in the Vidovačka Reka

Slope of siltation is the slope of the upper surface of the deposited material, which can be considered as the equilibrium bed slope in the specific conditions of the torrent channels with the constructed dams. The formation of siltation is a complex process which is influenced by many factors, most significant being: natural bed slope, competent velocity, depth of flow, density of torrential water and sediment...

High quality model for compression of medical images in telemedicine

Generally lossless compression should be used for ROI (Region of Interest) and lossy compression should be used for ROB (Region of Background) with a lower quality. In existing system, Region of Interest (ROI) is selected manually, but ROI is selected automatically in the proposed method, pre-processing is done to improve the visual quality of the image. Segmentation is carried out accurately and efficiently using...

Efficacy of Panchagavya on seed invigoration of biofuel crops

Studies on organic seed fortification with Jatropha curcas and Pongamia pinnata using ‘Panchagavya ’at one, two, three, four and five per cent concentrations with the three different soaking durations revealed that Panchagavya at 2 and 5% with the soaking duration of 16 and 8 h were superior than the control and other concentrations in terms of germination and seedling vigour for Jatropha curcas and Pongamia...

Active islanding detection technique using rate of change of negative sequence of voltage injection

Recently, the penetration of Distributed Generation (DG) at medium and low voltages in utility networks is increasing in developed countries and takes special place for them worldwide. Due to the DGs advantages, including use of Renewable Energy which do not pollute environment and has endless nature, the application of DGs can potentially reduce the need for traditional system expansion, controlling a potentially huge...

Analyzing the woodturning process using Taguchi methodology for dynamic systems

This paper presents a study of the woodturning performance and efficiency using the Taguchi methodology for dynamic systems. According to this methodology, the woodturning process was characterized by two generic functions: for the first one, the specific cutting energy is related linearly to the cutting power, in the second with the amount of cut. These parameters were measured depending on two control factors namely...

Integrated nutrient management and LCC based nitrogen management on soil fertility and yield of rice (Oryza Sativa L.)

The experiment was conducted at lowland series of wet lands, International Rice Research Institute (IRRI) Farm, Los Banos, Laguna, Philippines. The rice variety PSBRc 82 was raised during wet season (June – October), and the experiment was laid out in randomized block design with four replications. There were eleven treatments viz., control, recommended NPK fertilizer, -N, -P, -K, LCC 3, LCC 4, LCC 5, 100% N as...
