Mobility Control for Machine-to-Machine LTE Systems

open access: yesCoRR, 2011
In this paper, we propose an efficient mobility control algorithm for the downlink multi-cell orthogonal frequency division multiplexing access (OFDMA) system for co-channel interference reduction. It divides each cell into several areas. The mobile nodes in each area find their own optimal position according to their present location.

Efficiency Improved Load Sensing System—Reduction of System Inherent Pressure Losses

open access: yesEnergies, 2017
Although more efficient than e.g., constant flow systems, hydraulic load sensing (LS) systems still have various losses, e.g., system inherent pressure losses (SIPL) due to throttling at pressure compensators.

Refining Mobile UML State Machines [PDF]

open access: yes, 2004
We study the semantics and refinement of mobile objects, considering an extension of core UML state machines by primitives that designate the location of objects and their moves within a network. Our contribution is twofold: first, we formalize the semantics of state machines in MTLA, an extension of Lamport's Temporal Logic of Actions with spatial ...

Retroviral integration into nucleosomes through DNA looping and sliding along the histone octamer

open access: yesNature Communications, 2019
Retroviral integrases catalyze the insertion of viral DNA into the host cell DNA and can use nucleosomes as substrates for integration. Here the authors present the 3.9 Å cryo-EM structure of prototype foamy virus integrase after strand transfer into ...

Field Setup and Assessment of a Cloud-Data Based Crane Scale (CCS) Considering Weight- and Local Green Wood Density-Related Volume References

open access: yesCroatian Journal of Forest Engineering, 2022
When investigating the forwarding process within the timber supply chain, insufficient data often inhibits long-term studies or make real-time optimisation of the logistics process difficult. Information sources to compensate for this lack of data either
