The phrase "are defined where" is correct and usable in written English.
It can be used in contexts where you are specifying conditions or locations for definitions or parameters in a discussion, particularly in technical or academic writing.
Example: "The variables in this equation are defined where x is greater than zero."
Alternatives: "are specified when" or "are established in cases where".
Within a contingent valuation (CV) survey ordering effects are defined where responses to a given question vary in a theoretically unanticipated manner according to the positioning of that question relative to others in the survey instrument.
Second to arrive on my desk was a project for the Dutch Tax and Customs Administration (Belastingdienst), in which we were asked to develop a concept-extraction toolkit that would allow them to make explicit where concepts are defined, where they are reused, and how they relate to other concepts (e.g., from an external thesaurus).
Limited wavelength ranges are defined where the coated sphere model can be used to obtain the effective radius or the volume composition of the particle.
In 802.15.4 [1], two types of devices, reduced function device (RFD) and full function device (FFD), are defined, where only an FFD may be the coordinator of a personal area network (PAN) or cluster.
A set of priority classes are defined, where the higher priority class uses the window [ 0,2j+1−1] and the lower priority class uses the window [ 2j+1,2j+2−1], where j is the backoff stage.
Proof Since p, q ∈ Λ are hyperbolic periodic points, there are ϵ ( p ) > 0 and ϵ ( q ) > 0 such that W ϵ ( p ) σ ( p ) and W ϵ ( q ) σ ( q ) are defined, where σ = s, u.
An operating region can then be defined where there is high confidence that the method will operate reliably.
An evaluation framework is defined where transport efficiency is studied in a number of dimensions, including driving efficiency, delivery reliability, energy efficiency and service efficiency.
A region in the experimental space can be defined where the purification factor is always higher than 5.5 with yields exceeding 80%.
From the distortions an approach length can be defined where the upstream influence of the stagnation point at the tip of the plate is noticeable.
First, a directed D-HSP (G) is defined, where G is defined to be the UDG and it is connected.
