The phrase "an ad hoc implementation" is correct and usable in written English.
It can be used to describe a solution or method that is created for a specific purpose or situation, rather than being part of a general or standard approach.
Example: "The team developed an ad hoc implementation to address the unique challenges posed by the project."
Alternatives: "a temporary solution" or "a specific approach".
For instance, Kulkarni [16] has proposed a fine-grained access control model for key-value systems denoted K-VAC, which has been first designed to operate with Cassandra,11 and then extended for the integration into HBase.12 However, the proposed solution is an ad hoc implementation and cannot be easily ported or adapted to other systems.
To estimate divergence times, four methods were employed: PAML mcmctree [ 52], Multidivtime [ 53], R8S [ 54], and an ad hoc implementation of maximum parsimony [ 36].
The effects due to curved spacetime can therefore not be explained by a simple ad hoc implementation of proper time in a classical quantum mechanics scheme.
This resulted in a disjointed and ad hoc implementation processes and failure to complete the Plan-Do-Study-Act cycle, a finding documented in other action research [ 33].
In a report to the European Commission on foresight modelling, an expert group suggests addressing "the issues of cooperation and coordination across policy areas…as well as matters of institutionalization in contrast to the ad hoc implementation of foresight on a project-by-project basis" to create anticipatory governance and to unite foresight and decision-making practices [41].
An international proficiency study with 31 participants demonstrated that ad hoc implementation of molecular diagnostics was feasible and successful.
A lack of mechanistic understanding of these rules has so far necessitated their ad hoc implementation, likely contributing to the limited precision of present algorithms.
Credibility intervals for time estimates can easily be obtained when times are estimated for each sample drawn from the Markov chain, but not under this latter ad hoc implementation of integrated local clocks.
Systematism is needed both generally in the organization and specifically for individuals in the organization, in our case the doctors, to avoid ad hoc implementation of quality work, which is once again stressed in the National Board of Health and Welfare's newly compiled instructions on management systems for quality and patient security in health care [ 3].
Indeed, different from relational databases, views are not supported by all NoSQL datastores, and thus ad hoc implementations are required within several NoSQL datastores.
We are not aware of any off the self-software implementation but ad hoc implementations in Stata and R are described in additional file 1.
