TL;DR: In this paper, an exponential approximation method is used for the analysis of the radial spectra of an anomaly and its first order moments for obtaining accurate estimates of the depths to the top and bottom of the body.
Abstract: The spectra of gravity and magnetic anomalies due to a prismatic body can be expressed as sums of exponentials. The complex exponents of these exponentials are functions of frequency and locations of the corners of the body. An exponential approximation method is used for the analysis of the radial spectra of an anomaly and its first order moments for obtaining accurate estimates of the depths to the top and bottom of the body. A method has also been developed for determining approximately the location of the centroid of the body. When the location of the centroid and the depths to the top and bottom are known for the causative body, it is possible to calculate the horizontal dimensions with the help of the spectrum of the anomaly.

TL;DR: The straight line method as discussed by the authors is an algebraic arrangement of the equation of a straight line with a variable group and is used by reservoir engineers to measure the success of a successful operation.
Abstract: The material baknce equation &red by reservoir engineers is irrrrsrged algebrar”caliy, resuhittg in an equation of a straight line, The straight line method of ana[ysis imposes an adfit[mwl necessary condition that a successful suhttion of theimateria{ bafance equation should meet In addition, this algebraic arrangement attaches a dynamic meaning to the otherwise skrtic mata%l balance equation The straight line method requires the plotting of one ~ varkzble group vs ‘anokr variable group The sequence of the plotted po[nts as well as the general shape oj the resuititw plot is of utmost importance Therefore, one cantwt progum me metnoa ennrwy On a digital computer as is usually done in tize routine sohition of the material instance eqtiauon II mm memos M applied, then plotting and analysis are essential Only the appropriate equations and the method of analysis and interpretation with comments and discussion are presented in thiv paper Illustrative field examples for the various co= treated are deferred to a subsequent writing

TL;DR: This study demonstrates the performance analysis of such a biometric trait, i.e., the interpulse intervals of heartbeats that were calculated from electrocardiogram and photoplethysmogram of 99 subjects and suggests that the readily available IPI information can be a good source for generating EIs among BSN nodes.
Abstract: Security of the emerging body sensor network (BSN) in telemedicine applications is a crucial problem because personal medical information must be protected against flaws and misdeeds. The solution is, however, nontrivial because lightweight mechanisms have to be deployed to meet the stringent resource constraints of these networks. It has been suggested that the inherent ability of human body to transfer information is a unique and resource-saving method to secure wireless communications within a BSN. For example, physiological characteristics can be captured by individual sensors of a BSN to generate entity identifiers (EIs) for identifying nodes and even securing keying materials, i.e., by a biometric approach. This study demonstrates the performance analysis of such a biometric trait, i.e., the interpulse intervals (IPIs) of heartbeats that were calculated from electrocardiogram and photoplethysmogram of 99 subjects. Based on the characteristics of IPIs, a lightweight generation scheme of EIs is proposed. Individual randomness and group similarity of the generated EIs are then evaluated. False acceptance rate and false rejection rate are also calculated to measure the effectiveness of the proposed identification system. The results suggest that the readily available IPI information can be a good source for generating EIs among BSN nodes.
