Abstract: An approach is provided for removing outliers from road lane marking data (e.g., using two-phase filtering). The approach involves processing spatial data points representing a road lane into clusters, and filtering cluster(s) away from a main cluster from the clusters to generate an initial filtered data point set. The approach also involves calculating a degree of relationship among the data points of the initial filtered set based on a distance metric to generate group node(s) of the initial filtered set. The approach further involves for each group node, determining a probability that a spatial data point belongs in said each group node by comparing the spatial data point to a center of said each group node, and filtering the spatial data point from said each group node based on determining that the probability is less than a threshold to generate a final filtered data point set.

Abstract: An adaptor is disclosed for connecting a rotating electrical machine 12 to a prime mover 10. The adaptor comprises at least one air outlet. The adaptor is arranged to provide an increase in a cross-sectional area of air flow towards the outlet. In this way part of the dynamic pressure can be converted into additional static pressure rise through steady expansion of the air flow cross-section. This in turn may help to improve the overall amount of cooling air passing through the machine for a given fan input power.

Abstract: An approach is provided for a homomorphic cryptosystem for use in resource-constrained environments (e.g., vehicle-based use cases) or when computer resources are to be conserved. The approach involves, for example, generating a nonce at a first device (e.g., vehicle engine control unit (ECU)). The approach also involves performing a homomorphic operation on the nonce and a ciphertext to generate a resulting cipher. The ciphertext is provided by a second device (e.g., a data server). The approach further involves attaching the resulting cipher to a request payload (e.g., to request secure data from the data server). The approach further involves transmitting the request payload including the nonce to the second device (e.g., the server).
