BACKGROUND Multiple imputation is a commonly used method for handling incomplete covariates as it can provide valid inference when data are missing at random. This depends on being able to correctly specify the parametric model used to impute missing values, which may be difficult in many realistic settings. Imputation by predictive mean matching (PMM) borrows an observed value from a donor wit...

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...

The Pacific Meridional Mode (PMM) impacts tropical sea surface temperature variations, which in turn affect the PMM through excited atmospheric teleconnections. Previous studies linked this loop to Pacific-excited North Oscillation (NPO; second empirical mode of level pressure variability), while a recent study proposed linkage Aleutian low (AL) variability (the first mode). Unraveling their re...

This paper presents and studies the iteration-complexity of two new inexact variants of Rockafellar’s proximal method of multipliers (PMM) for solving convex programming (CP) problems with a finite number of functional inequality constraints. In contrast to the first variant which solves convex quadratic programming (QP) subproblems at every iteration, the second one solves convex constrained q...

Administration (EIA) provides analyses used to assess proposed energy and environmental policies and to make energy forecast for the Annual Energy Outlook (AEO). The tool used by EIA for these mid to long term forecasts is the National Energy Modeling System (NEMS), a large-scale model of energy supply, demand, prices, and technologies. One component of NEMS is the Petroleum Marketing Module (P...

Inter-frame structural motions are required to be small for classic Digital Image Correlation (DIC) algorithms, which severely limits the application of technique in large rotation cases. To solve problem, multiple methods obtain initial guesses deformation parameters have been introduced over recent years. However, success rate is still limited by angles and efficiency low due extra calculatio...

The development teams who are geographically spread, culturally mixed and mainly depend on information and communication technology (ICT) for communication is defined as a global virtual teams (GVTs). Despite the advancement of technologies, achieving the efficient performance of GVTs remains a challenge. The reviewed literature has highlighted the importance of training and development, organi...

Purpose This paper proposes an SME oriented Industry 4.0 maturity framework to explore the interplay between manufacturing processes, performance measurement system and management practices (PMM). Given that fourth industrial revolution, famously referred as 4.0, is a new paradigm for firms, it crucial know ‘as-is’ state or of SMEs' processes link with their PMM. Despite availability numerous m...
