Prediction of land market value based on the real estate market in USA
(Wichita State University, 20170428)The Land Market Value, defined as the total value of land and quantity data are derived from data on housing values, is an important factor in the estimation of structure costs using price indexes for housing and construction ... 
Unexpected radial limit
(Wichita State University, 20170428)Consider a bounded solution f of the prescribed mean curvature equation over a bounded domain ? ? R^2 which has a corner at which has a corner at (0, 0) of size 2? and assume the mean curvature of the graph of f is ... 
Measurement of the neutrino mixing angle theta(23) in NOvA
(American Physical Society, 20170410)This Letter reports new results on muon neutrino disappearance from NOvA, using a 14 kton detector equivalent exposure of 6.05 x 10(20) protons on target from the NuMI beam at the Fermi National Accelerator Laboratory. The ... 
Radial limits of capillary surfaces at corners
(Pacific Journal of Mathematics, 201705)Consider a solution f is an element of C2(Omega) of a prescribed mean curvature equation div del f/root 1+vertical bar del f vertical bar(2) = 2H (x, f) in Omega subset of R2, where Omega is a domain whose boundary ... 
On cusp solutions to a prescribed mean curvature equation
(Pacific Journal of Mathematics, 201705)The nonexistence of "cusp solutions" of prescribed mean curvature boundary value problems in Omega x R when Omega is a domain in R2 is proven in certain cases and an application to radial limits at a corner is mentioned. 
Hydrogenation of carbon dioxide over KPromoted FeCo bimetallic catalysts prepared from mixed metal oxalates
(John Wiley & Sons, Inc., 20170407)The hydrogenation of carbon dioxide over Kpromoted FeCo bimetallic catalysts prepared by sequential oxalate decomposition and carburization of FeCo with CO was studied in a fixedbed reactor at 240 degrees C and 1.2MPa. ... 
Estimation of a starshaped distribution function
(Taylor & Francis LTD, 2017)A life distribution function (DF) F is said to be starshaped if F(x)/x is nondecreasing on its support. This generalises the model of a convex DF, even allowing for jumps. The nonparametric maximum likelihood estimation ... 
A comparison of some numerical conformal mapping methods for simply and multiply connected domains
(Wichita State University, 201605)This dissertation compares several methods for computing conformal maps from simply and multiply connected domains bounded by circles to target domains bounded by smooth curves and curves with corners. We discuss the use ... 
Ages of 70 dwarfs of three populations in the solar neighborhood: considering O and C abundances in stellar models
(IOP Publishing Ltd, 20161215)Oxygen and carbon are important elements in stellar populations. Their behavior refers to the formation history of the stellar populations. C and O abundances would also obviously influence stellar opacities and the overall ... 
Recovery of timedependent volatility in option pricing model
(IOP Publishing Ltd, 20160929)In this paper we investigate an inverse problem of determining the timedependent volatility from observed market prices of options with different strikes. Due to the non linearity and sparsity of observations, an analytical ... 
Isotonic regression through the Merge and Chop Algorithm for application in statistical inference
(Wichita State University, 201605)In this paper, the theory for the application of the Merge and Chop Algorithm are defined and proven. The algorithm is used to find isotonic regressions in more situations than comparable methods. A program is included ... 
Computation of Stokes waves using conformal mapping
(Wichita State University, 201605)In this paper we study the time dependent water wave problem for Stokes waves on water of infinite and finite depth using numerical conformal mapping techniques. We begin by briefly reviewing Fornberg's numerical conformal ... 
The effects of individual metal contents on isochrones for C, N, O, Na, Mg, Al, Si, and Fe
(IOP Publishing, 20160728)The individual characteristics of C, N, O, Na, Mg, Al, Si, and Fe on isochrones have been investigated in this study. Stellar models have been constructed for various mixtures in which the content of each element is changed ... 
FischerTropsch synthesis: effect of Cu, Mn and Zn addition on activity and product selectivity of cobalt ferrite
(Royal Society of Chemistry, 2016)The effect of Cu, Mn and Zn addition on cobalt ferrite was investigated for FischerTropsch synthesis (FTS). Oxalate coprecipitation followed by decomposition under inert conditions was used to obtain various metal ...
