The phrase "across different systems" is correct and can be used in written English.
You can use this phrase to describe when something, such as an action or process, is applicable to various types of systems. For example, "The new safety protocols must be implemented across different systems in the factory."
Here, a context of use as a whole refers to the simultaneous analysis of usability issues across different system within the same domain.
The results show that the proposed fuzzy approach remains robust across different system configurations and flexibility levels, and performs favourably compared to the other algorithms.
In other words, a comparison of single (or few) realizations across different system sizes is meaningless, as the response of single realizations may be dominated by microstructure fluctuations whereas systematic trends are borne out only upon ensemble averaging.
Multi-GNSS double difference combination strategies include loose combination (LC) in which each of the systems uses its own reference satellite and no double differences are formed across systems (Zhang et al. 2003), and tight combination (TC) in which two systems use the same reference satellite and permitting double differences across different systems (Julien et al. 2003).
This study adds to the existing literature by showing that the relationship between literacy and systolic blood pressure is complex and may differ significantly across different systems of healthcare delivery.
As Nate Silver did originally, you can average scores across different systems to get a good idea of where a candidate stands.
As well as a single-search function there are plans to make it easier to match biometric data, such as fingerprints, across different systems.
It allowed Adobe to produce a product that was superior in all respects: it looked good, was truly portable across different systems, and had a compact file size that made transferring files quick and easy.
Thirdly, we implemented an additional analysis program that presents the interactions of threads across different systems.
However, such personal identity attributes also vary in terms of availability and reliability across different systems.
These indices are often context specific and so is their performance across different systems.
