MF-CFI: A fused evaluation index for camouflage patterns based on human visual perception

The evaluation index of camouflage patterns is important in the field of military application. It is the goal that researchers have always pursued to make the computable evaluation indicators more in line with the human visual mechanism. In order to make the evaluation method more computationally intelligent, a Multi-Feature Camouflage Fused Index (MF-CFI) is proposed based on the comparison of grayscale, color and texture features between the target and the background. In order to verify the effectiveness of the proposed index, eye movement experiments are conducted to compare the proposed index with existing indexes including Universal Image Quality Index (UIQI), Camouflage Similarity Index (CSI) and Structural Similarity (SSIM). Twenty-four different simulated targets are designed in a grassland background, 28 observers participate in the experiment and record the eye movement data during the observation process. The results show that the highest Pearson correlation coefficient is observed between MF-CFI and the eye movement data, both in the designed digital camouflage patterns and large-spot camouflage patterns. Since MF-CFI is more in line with the detection law of camouflage targets in human visual perception, the proposed index can be used for the comparison and parameter optimization of camouflage design algorithms.

Real-time prediction of projectile penetration to laminates by training machine learning models withfinite element solver as the trainer

Studies on ballistic penetration to laminates is complicated, but important for design effective protection of structures. Experimental means of study is expensive and can often be dangerous. Numerical simu-lation has been an excellent supplement, but the computation is time-consuming. Main aim of this thesis was to develop and test an effective tool for real-time prediction of projectile penetrations to laminates by training a neural network and a decision tree regression model. A large number of finite element models were developed;the residual velocities of projectiles fromfinite element simulations were used as the target data and processed to produce sufficient number of training samples. Study focused on steel 4340tpolyurea laminates with various configurations. Four different 3D shapes of the projectiles were modeled and used in the training. The trained neural network and decision tree model was tested using independently generated test samples using finite element models. The predicted projectile velocity values using the trained machine learning models are then compared with thefinite element simulation to verify the effectiveness of the models. Additionally, both models were trained using a published experimental data of projectile impacts to predict residual velocity of projectiles for the unseen samples. Performance of both the models was evaluated and compared. Models trained with Finite element simulation data samples were found capable to give more accurate predication, compared to the models trained with experimental data, becausefinite element modeling can generate much larger training set, and thus finite element solvers can serve as an excellent teacher. This study also showed that neural network model performs better with small experimental dataset compared to decision tree regression model.

Better is the Neighbor?

Abstract

This study applies the Sequential Panel Selection Method (SPSM), to investigate the convergence properties of the military expenditure of the North Atlantic Treaty Organization (NATO) during the period of 1990–2015. Compared to the traditional methods, SPSM considers fundamentally general spatial homogeneous and heterogeneous relationships with countries and examines the evolution of military expenditure. We find that four-fifths of NATO member countries have been convergent with the UK, but no country’s military expenditure is convergent with the US. This means that there is no significant linkage effect in the US for NATO military expenditure. While they are allies of the US, the majority of NATO member countries’ military expenditures are consistent with UK military expenditure. The main reasons are due to the geographical space layout and the international relationship convergence. The results indicate that more than four-fifths of NATO member countries have been coordinated with convergence theory and spillover effect.     

Do Military Expenditures Crowd-out Health Expenditures? Evidence from around the World, 2000–2013

Abstract

The paper examines the relationship between health and military expenditures using pooled cross-sectional (197 countries) and time series (2000–2013) data. Simultaneous equation models were employed to estimate the relationship between an array of public sector expenditures in order to address potential endogeneity. Our empirical findings strongly support the crowding-out hypothesis whereby increased military expenditures reduce the capacity of government to direct expenditures to health expenditures. These findings were robust to alternative specifications explored in the sensitivity analyses. Compared with upper-middle-income countries, the crowding-out effect became more pronounced among lower-middle-income countries. Consequently, this study shows that increased military expenditures negatively impacts health expenditures, and therefore poses as an important risk factor for population health and individual well-being. Moreover, it is the poorest of nations that are most sensitive to the negative effects of increased military expenditures.
