Nonparametric Lag Selection for Additive Models based on the Smooth Backfitting Estimator  [PDF]
Zheng-Feng Guo, Lingyan Cao, Ying He
Theoretical Economics Letters (TEL) , 2011, DOI: 10.4236/tel.2011.12004
Abstract: This paper proposes a nonparametric FPE-like procedure based on the smooth backfitting estimator when the additive structure is a priori known. This procedure can be expected to perform well because of its well-known finite sample performance of the smooth backfitting estimator. Consistency of our procedure is established under very general conditions, including heteroskedasticity.
Predictability of the Consistency of Porridges Using Mixtures of Different Flours  [PDF]
Irene S. T. de Carvalho, Yvonne Granfeldt, Ann-Charlotte Eliasson, Petr Dejmek
Food and Nutrition Sciences (FNS) , 2013, DOI: 10.4236/fns.2013.49121

The purpose of this study was to investigate the predictability of the consistency of blended porridges based on the volume fractions of separate porridges made from orange-fleshed sweet potato, cowpea, dehulled soybean, dehulled sorghum and maize flour (dehulled, commercial and germinated). Accurate predictions could be made for 13 of the 21 blends investigated. The consistency of porridge consisting of mixtures of cowpea with orange-fleshed sweet potato, and cowpea with dehulled soybean was lower than expected, and was attributed to the different size distributions of the swollen flour particles. Blends containing germinated maize showed significantly lower consistency than expected in both porridges with starchy continuous phase and porridges with proteinaceous continuous phase. It was thus concluded that both amylolytic and proteolytic activity are of importance in the ameliorating effects of germinated maize.

Strong Consistency of Kernel Regression Estimate  [PDF]
Wenquan Cui, Meng Wei
Open Journal of Statistics (OJS) , 2013, DOI: 10.4236/ojs.2013.33020

In this paper, regression function estimation from independent and identically distributed data is considered. We establish strong pointwise consistency of the famous Nadaraya-Watson estimator under weaker conditions which permit to apply kernels with unbounded support and even not integrable ones and provide a general approach for constructing strongly consistent kernel estimates of regression functions.

Can Really Regularized Amplitudes Be Obtained as Consistent with Their Expected Symmetry Properties?  [PDF]
OrimarOrimar Ant?nio Battistel, Gilson Dallabona, Marcus Vinicios Fonseca, Luciana Ebani
Journal of Modern Physics (JMP) , 2018, DOI: 10.4236/jmp.2018.96070
Abstract: Through a very detailed investigation involving a set of simple perturbative amplitudes we show that the answer for the question put in the title of the present work is: undoubtedly NO! We are not restricting the sentence to the amplitudes which are considered as anomalous. The referred investigation is performed by using a procedure alternative to the traditional regularization methods. In the context of such a strategy the amplitudes are not modified in intermediary steps of the calculation, like traditional regularization procedures do, and only the validity of the linearity in the integration operation is assumed in the operations made in Feynman integrals typical of the perturbative calculations. The central point of the investigation is the question related to the consistent interpretation of the amplitudes. For these purposes, in all amplitudes having power counting indicating the possibility of divergences, the relations among Green functions, Ward identities and low energy limits are analyzed, in a model having different species of massive 1/2 spin fermions coupled to spin 0 and 1 (even and odd parity) boson fields, formulated in a space-time dimension D=1+1. We show that the maintenance of the linearity in operations involving Feynman integrals excludes the possibility of an anomalous term in the Ward identity relating the axial-vector and the pseudo-scalar-vector two point functions amplitudes. In addition, we show that it is not possible the maintenance of Ward identities and low energy limits in a consistent way if the amplitudes of the perturbative calculations are quantities to be regularized, just because there is no regularization method which is capable to give acceptable results for the divergent objects present in the calculations. This conclusion includes the Dimensional Regularization method which cannot give unique results if the linearity and the symmetric integration are simultaneously required in Feynman integrals. The qualitative conclusions apply in an equally-way in other space-time dimensions having, therefore, implications in many phenomenological consequences of quantum field theories stated through perturbative solutions.

Apply AHP for Resource Allocation Problem in Cloud  [PDF]
Avtar Singh, Kamlesh Dutta
Journal of Computer and Communications (JCC) , 2015, DOI: 10.4236/jcc.2015.310002
Abstract: Cloud computing is an emerging paradigm with many applications that are integrated with IT organization having the freedom to migrate services between different physical servers. Analytic Hierarchy Process (AHP) with a pairwise comparison matrix technique for applications has been used for serving resources. AHP is a mathematical technique for multi-criteria decision-making used in cloud computing. The growth in cloud computing for resource allocation is sudden and raises complex issues with quality of services for selecting applications. Finally, based on the selected criteria, applications are ranked using the pairwise comparison matrix of AHP to determine the most effective scheme. The presented AHP technique represents a well-balanced multi criteria priorities synthesis of various applications effect factors that must be taken into consideration when making complex decisions of this nature. Keeping in view wide range of applications of cloud computing an attempt has been made to develop multiple criteria decision making model.

Abstract: metacase tools offer a similar functionality than conventional case tools for arbitrary graphical notations, once these notations had been suitably specified. the main obstacle affronted when using these tools, is the specification of the consistency rules that must be taken into account when using the graphical notation. in this paper, we present the specifications of two consistency rules of the uml class diagram on the metacase tool dome, encoded on the programming language alter. in addition, we analyze not only the specification of the structural features, but also the specification of the consistency rules of the uml class diagram in dome, comparing with the uml specification provided by omg.

Logical and historical determination of the Arrow and Sen impossibility theorems

Economic Annals , 2007, DOI: 10.2298/eka0772007b
Abstract: General classification of mathematical statements divides them into universal, those of the form xA , and existential ЭxA ones. Common formulations of impossibility theorems of K. J. Arrow and A. K. Sen are represented by the statements of the form "there is no x such that A". Bearing in mind logical equivalence of formulae ЭxA and x A, we come to the conclusion that the corpus of impossibility theorems, which appears in the theory of social choice, could make a specific and recognizable subclass of universal statements. In this paper, on the basis of the established logical and methodological criteria, we point to a sequence of extremely significant "impossibility theorems", reaching throughout the history of mathematics to the present days and the famous results of Arrow and Sen in field of mathematical economics. We close with specifying the context which makes it possible to formulate the results of Arrow and Sen accurately, presenting a new direct proof of Sen’s result, with no reliance on the notion of minimal liberalism. .
