Design Of Sksp-R Plan For Popular Statistical Distributions, Jaffer Hussain, S. Balamurali, Muhammad Aslam
Design Of Sksp-R Plan For Popular Statistical Distributions, Jaffer Hussain, S. Balamurali, Muhammad Aslam
Journal of Modern Applied Statistical Methods
The design of a Skip-lot sampling plan of type SkSP-R is presented for time truncated life test for the Weibull, Exponentiated Weibull, and Birnbaum-Saunders lifetime distributions. The plan parameters of the SkSP-R plan under these three distributions are determined through a nonlinear optimization problem. Tables are also constructed for each distribution. The advantages of the proposed plan over the existing sampling schemes are discussed. Application of the proposed plan is explained with the help of an example. The Birnbaum-Saunders distribution is economically superior to other two distributions in terms of minimum average sample number.

Grassland Landscape Design: Working With Land-Managers, C. J. Pearson, R. K. Mann, I. G. Mann
Grassland Landscape Design: Working With Land-Managers, C. J. Pearson, R. K. Mann, I. G. Mann
IGC Proceedings (1993-2023)
We are entering an era of landscape design in order to simultaneously tackle largescale issues such as salinity and rising water tables, whole-farm profitability and the maintenance or enhancement of rural communities. In Australia, an important element of landscape design will be the reintroduction or broadening of the base of perennial grasses within farm systems. The goal of this project was to accelerate awareness and adoption of perennial grasses in a large but ecologically-specific area, namely the already-cleared steep uplands in the high rainfall recharge areas of the Murray-Darling Basin. We used a participatory model, in which land-managers made monthly …
Results With Methods For Measuring Herbage Mass In Situ, G. Nagy, I. Vinczeffy, K. Petõ
Results With Methods For Measuring Herbage Mass In Situ, G. Nagy, I. Vinczeffy, K. Petõ
IGC Proceedings (1993-2023)
Two indirect methods for estimating herbage mass in situ were investigated in a research programme. Electric capacitance and spectral reflectance measurements were made and estimated values were compared with cut herbage mass results. Vegetation indexes (VI) measured by spectroradiometer showed a high correlation with fresh herbage mass, but there was no correlation observed between VI and dry matter results. Equations installed in electric capacitance meter were not feasible for Hungarian conditions. The change of electric capacitance in the sward (CMR) gave no correlation with cut DM yields. The investigated indirect methods are not suitable for research or production use yet.
Application Of Municipal Biosolids To Bahiagrass Pasture: Trace Metals In Harvested Forage, R. M. Muchovej, J. E. Rechcigl
Application Of Municipal Biosolids To Bahiagrass Pasture: Trace Metals In Harvested Forage, R. M. Muchovej, J. E. Rechcigl
IGC Proceedings (1993-2023)
Municipal biosolids (sewage sludge) are the by-products of wastewater treatment plants and their production, worldwide, has steadily increased over the past years. Florida is one of the fastest growing states in the USA. Biosolids are readily and increasingly available throughout the state. Pasture fertilization has been shown to increase biomass and quality of bahiagrass (Paspalum notatum Flugge) dramatically in Florida sandy soils. Nevertheless, with low cattle prices, ranchers are forced to reduce fertilizers inputs. Biosolids contain considerable amounts of nutrients, especially nitrogen (N), phosphorus (P), sulphur (S), calcium (Ca), and micronutrients, and are inexpensive when compared with commercial fertilizers. …
Rangelands Vegetation Mapping At Species Composition Level Using The Spicla Method: SDm Based PiXel ClaSsification And Fuzzy Accuracy. A New Approach Of Map Making, A. G. Toxopeus, C. A. J. M. De Bie, E. H. Kloosterman, J. K. Mbaluka, P. K. Mwangi, L. G. J. Boerboom
Rangelands Vegetation Mapping At Species Composition Level Using The Spicla Method: SDm Based PiXel ClaSsification And Fuzzy Accuracy. A New Approach Of Map Making, A. G. Toxopeus, C. A. J. M. De Bie, E. H. Kloosterman, J. K. Mbaluka, P. K. Mwangi, L. G. J. Boerboom
IGC Proceedings (1993-2023)
Vegetation maps have been made since centuries. The vegetation cover was represented as homogeneous mapping units (polygons), representing different vegetation types, where each type consists a combination of different plant species (floristic composition). More recent, with the use of satellite imagery, the polygons have been replaced by pixels with similar content as the polygon maps. In both approaches, field-observations were linked to the mapping units (polygons or pixels) often resulting in a complex of different vegetation types per mapping unit. In our new approach field data (sample points) on presence and abundance of individual grass species are spatially extrapolated based …
Forensic Discoverability Of Ios Vault Applications, Alissa Gilbert, Kathryn C. Seigfried-Spellar
Forensic Discoverability Of Ios Vault Applications, Alissa Gilbert, Kathryn C. Seigfried-Spellar
Journal of Digital Forensics, Security and Law
Vault Applications are used to store potentially sensitive information on a smartphone; and are available on Android and iOS. The purpose of using these applications could be used to hide potential evidence or illicit photos. After comparing five different iOS photo vaults, each vault left evidence and photos behind. However, of the three forensic toolkits used, each produced different results in their scans of the phone. The media left behind was due to the photo vaults not protecting their information as claimed, and using basic obfuscation techniques in place of security controls. Future research will look at how newer security …
Mathematically Modeling Prey-Catching Behavior Of The Tomato Frog, Conrad Tyler, Sarah Marzen, Jenna Monroy
Mathematically Modeling Prey-Catching Behavior Of The Tomato Frog, Conrad Tyler, Sarah Marzen, Jenna Monroy
Spora: A Journal of Biomathematics
Many microhylid frog species, such as the tomato frog, Dyscophus sp., have demonstrated the ability to aim their tongues independently of head and jaw movements. However, a trade-off between tongue-aiming and head-only aiming exists in which the former allows for crypsis but lacks speed whereas the latter is faster but less accurate and more noticeable to prey. For frogs that can move their tongues independently of their heads, under what circumstances will they utilize each strategy, and why? We derive a model, dependent on factors relevant for prey-catching, for the probability the frog will turn its head (and not …
Adoption And Influence: Industry Evaluation Of The GrassgroTm Decision Support Tool, E. M. Salmon, A. D. Moore
Adoption And Influence: Industry Evaluation Of The GrassgroTm Decision Support Tool, E. M. Salmon, A. D. Moore
IGC Proceedings (1993-2023)
The GrassGro Decision Support tool (DS tool) (Donnelly and Moore, 1999) was released for commercial use in Australia with a training package in late 1997. An assessment of its adoption was made by a survey of 53 registered users in March 1999. An evaluation of the software and training package was made at training workshops by 92 users between 1997 and December 1999. The response rates to the survey and the evaluation were 62% and 82% respectively. Seventy six percent of survey respondents had analysed at least one problem with GrassGro and 27% had applied GrassGro to five or more …
