The operation principles of nanoscale devices are based upon both electronic and mechanical properties
of materials. Because these properties can be coupled, they need to be investigated simultaneously. At this
moment, however, the electronic structure calculations with custom-made long-range mechanical distortions are impossible, or expensive at best. Here we present a unified formalism to solve exactly the
electronic structures of nanomaterials with versatile distortions. We illustrate the formalism by investigating twisted armchair graphene nanoribbons with the least possible number of atoms. Apart from
enabling versatile material distortions, the formalism is capable of reducing computational costs orders of
magnitude in various areas of science and engineering.

Improving the material efficiency of furnishes in papermaking by stratification and chemical modifications
Oksanen, Antti (2012)In this thesis the surface chemistry of fibres and z-directional paper structure were modified in order to improve the material efficiency of the fibres in the papermaking process. Material efficiency was estimated by ... -
This is just the beginning : an interview study about Finnish food sector's material efficiency commitment
Tanskanen, Essi (2020)Globaali ilmastonmuutos ja sidosryhmäpaineet saavat yritykset etsimään parempia tapoja toimia ja käyttää materiaaleja. Green dealit ja muut vapaaehtoiset ympäristösopimukset ovat yksi tapa sopia yhdessä asioista, asettaa ... -
A Comparison of Methodological Approaches to Measuring Cycling Mechanical Efficiency
Matomäki, Pekka; Linnamo, Vesa; Kyröläinen, Heikki (Springer, 2019)Background: Much is known about theoretical bases of different mechanical efficiency indices and effects of physiological and biomechanical factors to them. However, there are only a few studies available about practical bases ... -
Energy-Efficient Edge Computing Service Provisioning for Vehicular Networks : A Consensus ADMM Approach
Zhou, Zhenyu; Feng, Junhao; Chang, Zheng; Shen, Xuemin Sherman (Institute of Electrical and Electronics Engineers, 2019)In vehicular networks, in-vehicle user equipment (UE) with limited battery capacity can achieve opportunistic energy saving by offloading energy-hungry workloads to vehicular edge computing nodes via vehicle-to-infrastructure ... -
Energy Efficient Resource Allocation in Heterogenous Software Defined Network : A Reverse Combinatorial Auction Approach
Zhang, Di; Chang, Zheng; Zolotukhin, Mikhail; Hämäläinen, Timo (IEEE, 2015)In this paper, resource allocation for energy effi- ciency in heterogeneous Software Defined Network (SDN) with multiple network service providers (NSPs) is studied. The considered problem is modeled as a reverse ...
