Abstract In this paper we generalize the Interior Point-Proximal Method of Multipliers (IP-PMM) presented in Pougkakiotis and Gondzio (Comput Optim Appl 78:307–351, 2021. 10.1007/s10589-020-00240-9 ) for solution linear positive Semi-Definite Programming (SDP) problems, allowing inexactness associated Newton systems. particular, combine an infeasible Point (IPM) with Proximal (PMM) interpret al...

Organizations are constantly seeking performance improvement through new technology, processes, and instruments. One instrument that received considerable attention during the last years is called Performance Measurement System (PMS). A PMS tracks actual performance of an organization, helps identifying weaknesses, and supports communication and decision-making processes. The aim of this paper ...

The segmentation and detection of various types of nodules in a Computer-aided detection (CAD) system present various challenges, especially when (1) the nodule is connected to a vessel and they have very similar intensities; (2) the nodule with ground-glass opacity (GGO) characteristic possesses typical weak edges and intensity inhomogeneity, and hence it is difficult to define the boundaries....

Seeking to contribute with the management of water resources in Itaipu Binacional reservoir region, this research aimed characterize dynamics evapotranspiration and evaluate performance different mathematical methods, which determine reference (ETo) from air temperature values. Fifteen municipalities were analyzed. After obtaining data series, ETo was estimated using six methods: Camargo (C), H...

In this paper, the performance of a Ring Laser Gyro based inertial navigation is investigated. Dynamic and stochastic modeling are applied to gyro simulation and performance evaluation. In the dynamic model, some parameters such as scale factor and environmental sensitivity have been determined, whereas in the stochastic model, the other parameters such as random drift and measurement noise...

data envelopment analysis (dea) is a technique used to compare efficiency in various sectors such as hospitals, chain stores, and dealerships. it represents a set of linear programming techniques and uses deter-ministic data (inputs and outputs), in stable conditions. the dea technique cannot be used when there is data with indeterministic nature, or when there is an environment with dynamic co...
