Carbon dioxide emissions embodied in international trade in Central Europe between 1995 and 2008

open access: yesMoravian Geographical Reports, 2015
Climate change and environmental policies are widely discussed, but much less is known about emissions embodied in goods traded internationally, and the distinction between emission producers and consumers.

Tightness in Product Spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1986
A product ∏ X i \prod {X_i} of topological spaces X i , i ∈ I {X_i},i \in I will be said to preserve tightness if \[ ∂ ( ∏

Dendrogram-directed design space exploration for DSM-based product modularization

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2022
Product modularization is an architecture design scheme for a product to manage its complexity as a system. The design methods for modularization often employ mathematical operations to achieve better modularization.

Fractional Vector Cross Product in Euclidean 3-Space

open access: yesInternational Journal of Analysis and Applications, 2023
In this research a new definition of fractional vector cross product of two vectors in Euclidean 3-space is presented. Using this new definition the formulae for Euclidean norm, fractional triple vector cross product, curl and divergence of fractional ...

High quality genomic resources for stored product insects: Presentation [PDF]

open access: yes, 2018
The expansion of genomic resources for stored product insects has largely been hampered by cost, time required for inbreeding, and technical issues that can arise during genome assembly from pooling multiple individuals together for DNA isolation and ...

Product of Two Fuzzy Normed Spaces and its Completion [PDF]

open access: yesEngineering and Technology Journal, 2012
The aim of this paper is to prove that the Cartesian product of two complete fuzzy normed space is again a complete fuzzy normed space. Also to prove that the Cartesian product of two complete fuzzy inner product spaces is a complete fuzzy inner product ...

Inequalities That Imply the Norm of a Linear Space Is Induced by an Inner Product

open access: yesMathematics, 2023
The aim of this paper is to investigate when a linear normed space is an inner product space. Several conditions in a linear normed space are formulated with the help of inequalities. Some of them are from the literature and others are new. We prove that
