HNN- EXTENSIONS OF FINITE INVERSE SEMIGROUPS
(POLITECNICO DI M ILANO D EPARTMENT OF M ATHEMATICS, 2014)
The concept of HNN-extensions of groups was introduced by Higman, Neumann and Neumann in 1949. HNN-extensions and amalgamated free products have played a crucial role in combinatorial group theory, especially for algorithmic ...
The Gates of the City of Jerusalem in the Fatimid and Saljuq Periods (969-1099 AD)
(The University of Jordan, The Deanship of Academic Research and Quality Assurance, 2017-05-03)
This study discusses the gates of the city of Jerusalem during the Fāṭimid and Saljūq periods through the study of historical sources, contemporary research on this subject and the results of archaeological excavations ...
CONTEXT-FREENESS OF THE LANGUAGES OF SCH UTZENBERGER AUTOMATA OF HNN-EXTENSIONS OF FINITE INVERSE SEMIGROUPS
(PUBLICATIONS DE L'INSTITUT MATHEMATIQUE, 2016)
We prove that the Schutzenberger graph of any element of the HNN-extension of a fnite inverse semigroup S with respect to its standard presentation is a context-free graph, showing that the language L recognized by this ...
Undecidability of the word problem for Yamamura’s HNN-extension under nice conditions
(Semigroup Forum, 2016-04)
The solvability of the word problem for Yamamura’s HNN-extensions [S; A1, A2; ϕ] has been proved in some particular cases. However, we show that, contrary to the group case, the word problem for [S; A1A2; ϕ] is undecidable ...
Combining field performance with controlled environment plant imaging to identify the genetic control of growth and transpiration underlying yield response to water-deficit stress in wheat
Crop yield in low-rainfall environments is a complex trait under multigenic control that shows significant genotype×environment (G×E) interaction. One way to understand and track this trait is to link physiological studies ...
The Image of Palestine in the Narratives of Refugees: A Comparative Study of Two Refugee Camps - Qalandia in Palestine and Al Yarmouk in Syria
(Ibrahim Abu-Lughud Institute of International Studies, Birzeit University, 2011)
Optimal designs for dose-finding in contingent response models
(University of Missouri--Columbia, 2004-12)
We study D- and c-optimal designs for dose-finding with opposing failure functions. In particular, we study the contingent response models of Li, Durham and Flournoy (1995). In the contingent response model, there are two ...
Accounting for variation in designing greenhouse experiments with special reference to greenhouses containing plants on conveyor systems
(BioMed Central, 2013)
Background: There are a number of unresolved issues in the design of experiments in greenhouses. They include whether statistical designs should be used and, if so, which designs should be used. Also, are there thigmomorphogenic ...
Optimal designs for contingent response models with application to toxicity and efficacy
(Issac Newton Institute for Mathematical Sciences, 2011-12)
We generalize results in the literature to obtain a general family contingent response models. These models have ternary outcomes constructed from two Bernouli outcomes, where one outcome is only observed if the other ...
