21 Apr 2015TL;DR: A key pair validation method as mentioned in this paper allows a first party to generate a seed to define a private key, a public key, session key and validation field for the purpose of performing a cryptographic activity with a second party.
Abstract: A key pair validation method provides for a first party to generate a seed to define a private key, a public key, a session key and a validation field for the purpose of performing a cryptographic activity with a second party. The validation field is determined by encrypting the first party seed. The second party receives the first party public key and the validation field from the first party. The second party calculates a session key and utilizing the calculated session key, decrypts a cipher text to recover the first party's seed and the first party's private and public key. The recovered first party public key is compared to the received first party public key. If the received and recovered public keys match, the private-public key pair received from the first party is validated and the second party proceeds with the cryptographic task. If the received and recovered public keys do not match, the second party simply reports to the first party that the cryptographic task failed.

TL;DR: In this article, the first jet bundle of curves in Euclidean space is expressed as homogeneous spaces associated to a Galilean type group and certain Cartan connections on a manifold with values in the Lie algebra of the Galilean group are characterized as geometries associated to systems of second order ordinary differential equations.
Abstract: We express the first jet bundle of curves in Euclidean space as homogeneous spaces associated to a Galilean-type group. Certain Cartan connections on a manifold with values in the Lie algebra of the Galilean group are characterized as geometries associated to systems of second order ordinary differential equations. We show these Cartan connections admit a form of normal coordinates, and that in these normal coordinates the geodesic equations of the connection are second order ordinary differential equations. We then classify such connections by some of their torsions, extending a classical theorem of Chern involving the geometry associated to a system of second order differential equations.

TL;DR: In this paper, a matrix representing a graph and a first vector is received at the master controller, and a counter variable and an array to track dimensionality reduction for the matrix is initialized.
Abstract: A method includes receiving, at a master controller, a matrix representing a graph and a first vector, and initializing a counter variable and an array to track dimensionality reduction for the matrix. The method also includes multiplying a subset of the matrix based on the counter variable, by a subset of the first binary vector based on the counter variable. Multiplying includes providing, the vector and a matrix portion to a first processor, and the vector and another portion of the matrix to a second processor. The method also includes, at the processors, multiplying the vectors by the portions of the matrix and returning the results. The method also includes combining the results at the master controller. The method also includes incrementing the counter variable and updating the tracking array for larger dimensionality reduction of the matrix. The method also includes constructing the logical pathway based on the tracking array.

TL;DR: In this paper, the authors examined the reliability and validity of Varimax rotated principal component scores (VRPCS) in terms of orthogonality, reliability, and criterion-related validity.
Abstract: . Varimax rotated principal component scores (VRPCS) have previously been offered as a possible solution to the non-orthogonality of scores for the Big Five factors. However, few researchers have examined the reliability and validity of VRPCS. To address this gap, we use a lab study and a field study to investigate whether using VRPCS increase orthogonality, reliability, and criterion-related validity. Compared to the traditional unit-weighting scoring method, the use of VRPCS enhanced the reliability and discriminant validity of the Big Five factors, although there was little improvement in criterion-related validity. Results are discussed in terms of the benefit of using VRPCS instead of traditional unit-weighted sum scores.

14 Dec 2011TL;DR: In this article, the authors present a method for determining if a SIM card was removed and reinserted into a device by initially inserting the SIM card into the device, checking for the presence of the SIM device, if the device is present then returning to the second step, if not present then reporting that the device has been removed from the user-definable electronic device.
Abstract: A device for and method of determining if a SIM card was removed and reinserted into a device by initially inserting the SIM card into the device, checking for the presence of the SIM card, if the SIM card is present then returning to the second step, if the SIM card is not present then reporting that the SIM card has been removed from the user-definable electronic device, checking for the presence of the SIM card, if the SIM card is not present then returning to the fifth step, and if the SIM card is present then reporting that the SIM card has been reinserted into the device, and returning to the second step.
