Generalized Power Pompeiu Type Inequalities for Local Fractional Integrals with Applications to Ostrowski's Inequality
WOS: 000473350600021We establish some generalizations of power Pompeiu's inequality for local fractional integral. Afterwards, these results gave some new generalized Ostrowski type inequalities. Finally, some applications of these inequalities for generalized special means are obtained
Economic growth, trade and environmental quality in a two-region world economy
Cataloged from PDF version of article.This paper examines the linkages between international trade, environmental
degradation, and economic growth, in a dynamic North-South trade game. The
North produces manufactured goods by employing capital, labor, and a natural
resource that it imports from the South, using a neoclassical production function
subject to an endogenously improving technology. The South extracts the resource
using raw labor, in the process generating local pollution. Genetic algorithms (GA)
are used to search for optimal policies in the presence of local pollution and technology
spillovers from North to South. In the GA search for optimal regional policies,
both noncooperative and cooperative modes of trade are considered. Noncooperative
trade results in inefficiencies stemming from externalities. Though cooperative
trade policies are efficient, they lack credibility. A joint maximization of the global
welfare shows that transfer of technology is a viable route to improve world welfare
Fractional Ostrowski type inequalities for functions of bounded variaton with two variables
We first establish some fractional equalities for functions of bounded variation with two variables. Then we derive some fractional Ostrowski and Trapezoid type inequalities for functions of bounded variation with two variables. In addition, we give some Midpoint inequalities as special cases of our main results.WOS:0005415092000122-s2.0-8508947064
Conformance relations for distributed testing based on CSP
Copyright @ 2011 Springer Berlin HeidelbergCSP is a well established process algebra that provides comprehensive theoretical and practical support for refinement-based design and verification of systems. Recently, a testing theory for CSP has also been presented. In this paper, we explore the problem of testing from a CSP specification when observations are made by a set of distributed testers. We build on previous work on input-output transition systems, but the use of CSP leads to significant differences, since some of its conformance (refinement) relations consider failures as well as traces. In addition, we allow events to be observed by more than one tester. We show how the CSP notions of refinement can be adapted to distributed testing. We consider two contexts: when the testers are entirely independent and when they can cooperate. Finally, we give some preliminary results on test-case generation and the use of coordination messages. © 2011 IFIP International Federation for Information Processing
Estelle-based test generation tool
A test design tool for functional analysis and test derivation of protocols formally specified using an extended finitestate machine model is presented. The formal description language supported is Estelle. The tool's main components include a compiler, a normalizer, a multiple module transition tour generator and several interactive programs. The tool is based on a static analysis of Estelle called normalization, which is explained in detail with various examples. The normalized specification facilitates graphical displays of the control and data flow in the specification by the interactive tools. Next discussed is test generation, which is based on verifying the control and data flow. First the data flow graph must be decomposed into blocks where each block represents the data flow in a protocol function. From the control graph the tool generates transition tours, and then test sequences are derived from the transition tour to test each function. The performance of the tool on various applications is also included. © 1991
Spatially Selective Assembly of Quantum Dot Light Emitters in an LED Using Engineered Peptides
Cataloged from PDF version of article.Semiconductor nanocrystal quantum dots are utilized in numerous applications in nano- and biotechnology. In device applications, where several different material components are involved, quantum dots typically need to be assembled at explicit locations for enhanced functionality. Conventional approaches cannot meet these requirements where assembly of nanocrystals is usually material-nonspecific, thereby limiting the control of their spatial distribution. Here we demonstrate directed self-assembly of quantum dot emitters at material-specific locations in a color-conversion LED containing several material components including a metal, a dielectric, and a semiconductor. We achieve a spatially selective immobilization of quantum dot emitters by using the unique material selectivity characteristics provided by the engineered solid-binding peptides as smart linkers. Peptide-decorated quantum dots exhibited several orders of magnitude higher photoluminescence compared to the control groups, thus, potentially opening up novel ways to advance these photonic platforms in applications ranging from chemical to biodetection. © 2011 American Chemical Society
Thermal Degradation of Adsorbed Bottle-Brush Macromolecules: Molecular Dynamics Simulation
The scission kinetics of bottle-brush molecules in solution and on an
adhesive substrate is modeled by means of Molecular Dynamics simulation with
Langevin thermostat. Our macromolecules comprise a long flexible polymer
backbone with segments, consisting of breakable bonds, along with two side
chains of length , tethered to each segment of the backbone. In agreement
with recent experiments and theoretical predictions, we find that bond cleavage
is significantly enhanced on a strongly attractive substrate even though the
chemical nature of the bonds remains thereby unchanged.
We find that the mean bond life time decreases upon adsorption by
more than an order of magnitude even for brush molecules with comparatively
short side chains $N=1 \div 4$. The distribution of scission probability along
the bonds of the backbone is found to be rather sensitive regarding the
interplay between length and grafting density of side chains. The life time
declines with growing contour length as ,
and with side chain length as . The probability
distribution of fragment lengths at different times agrees well with
experimental observations. The variation of the mean length of the
fragments with elapsed time confirms the notion of the thermal degradation
process as a first order reaction.Comment: 15 pages, 7 figure
Novel results on Hermite-Hadamard kind inequalities for -convex functions by means of -fractional integral operators
We establish new integral inequalities of Hermite-Hadamard type for the
recent class of -convex functions. This is done via generalized
-Riemann-Liouville fractional integral operators. Our results generalize
some known theorems in the literature. By choosing different values for the
parameters and , one obtains interesting new results.Comment: This is a preprint of a paper whose final and definite form is a
