It can be used when discussing a specific role or purpose that something serves within a larger context.
Example: "In this system, a single function of the software is to manage user data efficiently."
Alternatives: "one role of" or "a sole purpose of".
The traditional microencapsulated phase change materials (PCMs) only have a single function of thermal energy storage.
Nowadays, most research results on ecosystem services in Karst areas are limited to a single function of an ecosystem service.
It is shown that the ozone absorption is practically a single function of the gas/liquid ratio while the removal efficiency of the odorous material is a single function of the ozone dose for a specified U-tube configuration.
The statute at issue in Staples defined "a firearm" by its physical features such as the length of its barrel and its capacity to shoot more than one shot with a single function of the trigger.
In the case in which the material is a plane sheet, the rheological behaviour is described by a single function of the current angle between the fibre directions.
It is shown that by using the relative measure concept, a distribution function, the expectation operator, and all the familiar probabilistic parameters can be constructed starting from a single function of time.
This theorem can be viewed as a generalization of Banach's contraction mapping theorem, generalizing from the existence of an attractive fixed point of a single function to the existence of an attractor of a finite set of functions.
It is important to note that these simulations are typically computationally expensive, consuming several minutes for a single function evaluation of acceptable fidelity for a complex composite part.
Importantly, the OR system fulfills a single function, namely detection of an almost infinite number of odorant molecules.
InsertionMapper consists of four modules, each designed for a single function or a group of cohesive functions in the whole workflow.
Wavelets constitute a family of functions constructed from dilation and translation of a single function called the mother wavelet.
