Abstract
The Physical Protection System (PPS) plays an important role to ensuring the security of each nuclear facility from theft, sabotage and other illegal actions. Evaluation of the effectiveness of the PPS must be performed periodically to ensure that the PPS objective requirements are met and we can obtain the reliable PPS. The objective of this study is to evaluate the physical protection system performance using adversary-path analysis for hypothetical nuclear reactor facility in anticipating attacks with the highest consequences. We perform the calculation of several adversary-path based on sabotage scenario using a computer model. The calculation results provide feedback for the PPS designer whether to accept the current design or will strengthen it to obtain the reliable PPS.

Abstract
Two floating spheres are attracted to each other, if the initial separation distance is less than several times of diameter. This is also affected by portion of immersed volume of the sphere. The interaction between the two spheres is produced by unbalanced surface tension of each ball with the surrounding fluid. Position of each ball is observed using video camera and then the information is extracted using a in-house software based on OpenCV library. Due to difficulty of maintaining reproducible initial conditions, one the spheres sometimes moves to approach to the second, and not both move to aproach each other. In all these cases spheres position is transformed to center of mass position so that all position data as function of time will show a symmetry with center of mass position. Taking differential with respect to time two times, acceleration of each sphere will be obtained. The this information form of interaction can be deducted. A simulation using molecular dynamics method and theoretical approach will show the relation between form of interaction and the related acceleration function of time.

Abstract
Abstract. Road and modelled in grids (G) and vehicles (cars) modelled in particles as agents (A) in this analytical model. Agents given two types of different traffic engineering flows, One-Way (F1) and Multi-Way (F2). F2 is old model replaced by F1 due to creating dense traffic. F1 model is a new model applied by Department of Transportation to avoid vehicle conjunction in Sukajadi rd. Using Agent-Based Model approach to model and simulate two type of conditions and produce analytical result to determine the best traffic engineering flow (F). Agents divided at three types: obedient (A1), ordinary (A2), and disobedient (A3). Main concern of this study is cumulation or congestion on each connected road. Directions (D) layered as matrices. Speed is considered the same on all agents due to complexity of this study.

Abstract
Brazil nut effect is a phenomenon in which large-size particle lift up when vibrated vertically on granular system. This phenomenon has been studied both through experiments and computational simulations. One parameter that can be extracted from this phenomenon is the final height of the large-size particle. However, due to the large number of input parameters that affect the final results, the way to predict is still the subject of study. In this study, we used artificial neural network (ANN) as a method to predict the final results of experiments through molecular dynamic simulations with different input parameters. The different input parameters were created by generating random numbers of the appropriate range. After the simulation was carried out and the final result was obtained, the input and final parameter data were used as a database for training ANN. To get optimal results, a comparison is made of various ANN model architectures.
