• Two contributions to order restricted inferences 

  Echart, Alexandra K. (Wichita State University, 2018-12)

  We are proposing two separate problems from order restricted inferences. The rst is a one-sided test for stochastic ordering of two distribution functions that protects against false positive conclusions because of model ...

• The effect of small time delays on large-scale systems 

  Almutairi, Shahah (Wichita State University, 2018-12)

  In this research, model reduction techniques are used to design optimal control strategies with low sensitivity in order to model uncertainty. The source of uncertainty encountered is the time delay, and the reduced-order ...

  Alsultan, Rehab; Ma, Chunsheng (SIAM Publ., 2019)

  A thin-tailed vector random field, referred to as a K-differenced vector random field, is introduced. Its finite-dimensional densities are the differences of two Besse! functions of second order, whenever they exist, and ...

• Inverse problem for one-dimensional wave equation with matrix potential 

  Khanfer, Ammar; Bukhgeim, Alexander L. (De Gruyter, 2019-01-20)

  We prove a global uniqueness theorem of reconstruction of a matrix-potential a (x, t) {a(x,t)} of one-dimensional wave equation □ u + a u = 0 {\square u+au=0}, x > 0, t > 0 {x>0,t>0}, □ = t 2 - x 2 {\square=\partial-{t}^ ...

• Unbiasedness of LRT on the homogeneity of means in MANOVA under general order restrictions 

  Hamdan, Mustafa; Hu, Xiaomi (Elsevier, 2019-05)

  In this paper a likelihood ratio test is developed through matrix projections for the hypothesis on the homogeneity of mean vectors in MANOVA. It is assumed that the mean vectors are under a general multivariate order ...

• Non-negatively curved 6-manifolds with almost maximal symmetry rank 

  Escher, Christine; Searle, Catherine (Springer Nature, 2019-01)

  We classify closed, simply connected, non-negatively curved 6-manifolds of almost maximal symmetry rank up to equivariant diffeomorphism.

• Time-varying isotropic vector random fields on compact two-point homogeneous spaces 

  Ma, Chunsheng; Malyarenko, Anatoliy A. (Springer, 2018)

  A general form of the covariance matrix function is derived in this paper for a vector random field that is isotropic and mean square continuous on a compact connected two-point homogeneous space and stationary on a temporal ...

• A pseudo restricted MLE under multivariate order restrictions and its algorithm 

  Hu, Xiaomi (Taylor & Francis, 2018-12-21)

  It is shown in this paper that a quasi order for the vectors in Rp is a cone induced if and only if the order is preservable under limits and under linear combinations with non-negative coefficients. For the mean vectors ...

• Increased CO2 hydrogenation to liquid products using promoted iron catalysts 

  Shafer, Wilson D.; Jacobs, Gary; Graham, Uschi M.; Hamdeh, Hussein H.; Davis, Burtron H. (Elsevier, 2019-01)

  The effect of alkali promoter (K, Rb and Cs) on the performance of precipitated iron-based catalysts was investigated for carbon dioxide (CO2) hydrogenation. Characterization by temperature-programmed reduction with CO, ...

• A forward branching phase space generator for hadron colliders 

  Figy, Terrance M.; Giele, Walter T. (Springer Berlin Heidelberg, 2018-10)

  In this paper we develop a projective phase space generator appropriate for hadron collider geometry. The generator integrates over bremsstrahlung events which project back to a single, fixed Born event. The projection is ...

• Chapter 1 - Quantum neural computation of entanglement is robust to noise and decoherence 

  Behrman, Elizabeth C.; Nguyen, Nam H.; Steck, James E.; McCann, M. (Elsevier, 2017)

  Measurement and witnesses of entanglement remain an important issue in quantum computing. Most witnesses will work for only a very restricted class of states, while measurements commonly require lengthy procedures. Quantum ...

• A comparison of some numerical conformal mapping methods for simply and multiply connected domains 

  Badreddine, Mohamed; DeLillo, Thomas K.; Sahraei, Saman (American Institute of Mathematical Sciences, 2019-01)

  This paper compares some 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 of explicit ...

• Inverse source problems without (pseudo) convexity assumptions 

  Isakov, Victor, 1947-; Lu, Shuai (American Institute of Mathematical Sciences, 2018-08)

  We study the inverse source problem for the Helmholtz equation from boundary Cauchy data with multiple wave numbers. The main goal of this paper is to study the uniqueness and increasing stability when the (pseudo)convexity ...

  Gnanamani, Muthu Kumaran; Hamdeh, Hussein H.; Shafer, Wilson D.; Hopps, Shelley D.; Davis, Burtron H. (Elsevier, 2018-08-25)

  Iron carbide was prepared by the carburization of iron oxalate doped with various alkali metals in flowing CO at 400 degrees C. The addition of alkali metal (Li, Na, K, Rb or Cs) to iron oxalate was found to decrease the ...
