A configurable printing bed for a 3D printer includes a bed surface and linear actuators. The bed surface includes bed surface portions. Each of the bed surface portions is supported for independent movement. At least one of the bed surface portions includes a head that is twistable. When each of the bed surface portions is positioned at a reference level, the bed surface portions form different parts of a common plane. Each of the linear actuators is connected to at least one of the bed surface portions, respectively. The linear actuators are configured to generate the independent movement of the bed surface portions and to effect positioning of the bed surface portions. The linear actuators are configured to lower the bed surface portions in a staggered manner so that a release wave is generated and used to remove a 3D printed object from the printing bed.

In an approach for determining the date of planting of a crop growing in an agricultural field, a processor receives an aerial image of one or more agricultural fields in a pre-determined geographical region. A processor selects a plurality of points from the aerial image. A processor calculates a Vegetation Index of one or more crops growing at the plurality of points selected. A processor compares the Vegetation Index calculated for the one or more crops growing at the plurality of points selected to the Vegetation Index known for a plurality of historical reference signatures. A processor generates an actual signature. A processor cross-correlates the actual signature against the plurality of historical reference signatures to measure a degree of similarity. A processor identifies the one or more crops growing in the one or more agricultural fields in the pre-determined geographical region from the cross-correlation.

In a fully homomorphic encryption scheme, a method is provided for performing a homomorphic operation on a data set by applying an encrypted operand supplied as a ciphertext. A data set containing 'i' library vectors, each with 'j' coefficients is subjected to a pivot operation such that each set of common &#x2018;j&#x2019; coefficients is stored in respective library ciphertexts. A query ciphertext containing a query vector is then subjected to a homomorphic pivot operation to separate out its &#x2018;j&#x2019; coefficients into respective pivoted query ciphertexts. A more efficient homomorphic computation can then be carried out between the ciphertexts of the pivoted forms of the query and library vectors so as to compute an encrypted set of vector differences between the query vector and each of the library vectors.
