Simulation approaches generally fall into two categories: discrete time or discrete event. For military modeling and simulation needs, the two approaches typically align with virtual simulation, which implies human interaction with the simulation program, and constructive simulation, which implies no human interaction. The Air Force Research Laboratory develops and distributes AFSIM (Advanced Framework for Simulation, Integration, and Modeling) to a user community that uses both virtual and constructive simulation. This paper documents the software design and primary algorithms that provide AFSIM’s support for both modes, which is termed a hybrid simulation.

Computational Prototyping Environment (CPE) is a web-based portal designed to simplify running Department of Defense (DoD) modeling and simulation tools on the DoD Supercomputing Resource Center’s (DSRC) High Performance Computing (HPC) systems. The first of these tools to be deployed in the CPE is an application (app) to conduct parametric studies and view results using the CREATE-AV Helios CFD software. Initial capability includes hover (collective sweep) and forward flight (speed sweep) performance calculations. The CPE Helios app allows for job submission to a DSRC’s HPC system and for the viewing of results created by Helios, i.e., time series and volumetric data. Example data input and results viewing are presented. Planned future functionality is also outlined.

After many years of research, it has been concluded that Antikythera mechanism is a more complicated device than initially was thought. Recently, the rapidly increasing development of 3D modeling and simulation software, resulted in attempts to recreate the mechanism's 3D construction. These 3D replicas are based on advanced knowledge, gathered by the study of the mechanism remnants or the deciphered inscription on its surfaces. The latest decrypted inscriptions on the back door of the mechanism refers to planetary motion, which might be illustrated by a planetarium formation, which is absent from the remains of Antikythera mechanism. The authors propose a 3D reconstruction of this alleged planetarium, as a possible sequence of the existed mechanism's remains, compatible with the surviving inscriptions. Specifically, the authors introduce a lot of constructional differentiations compared to the other suggested, focusing mainly on measurements accuracy which this planetary system could perform.

Architecture Framework

With the wide variety of information systems and applications for motor transport and transport logistics control we have today, one may think we are already living in the digital era of general welfare, and digital tools would easily ensure sustainable development and prosperity of businesses. However, the experience of deployment and introduction of such solutions shows that their value for transport business is significantly lower than expected. Moreover, in some projects, business performance of transport companies had no correlation with introduction of information systems. In the best-case scenario, they provided for a slight decrease in document flow transaction costs. The change of the strategic status of a company in the transportation service market is a fairly complicated task, which, as analysis of literary sources shows, is achievable for few enterprises, primarily small and medium-sized businesses. Such situations show that information solutions were introduced without analyzing or assessing the business models of certain companies which could be used a basis for digital landscape of business as a whole. In recent years, the basic concept of forming a single information space of an enterprise has been the enterprise architecture. It provided for coordination between all the business processes in order to achieve a company’s strategic goals. The fundamentals of the concept were developed by J. Zachman in his famous Zachman Framework, and it was later developed with numerous models of enterprise architecture (e.g., TOGAF (Department of Defense Architecture Framework), GERAM (Generalised Enterprise Reference Architecture and Methodology), DoDAF (Department of Defense Architecture Framework)). However, currently some researchers note that sustainable corporate development should stem not only from a “correct assembly” of all its business elements, which was the purpose of enterprise architecture, but also from the interaction of these elements when reaching the emergence effect. In this context, one should pay attention to comprehensive activity analysis of a transport and logistics business using ontological and architecture approaches.

This paper reports design, modeling and simulation of MEMS based sensor working in dynamic mode with fully differential piezoresistive sensing for monitoring the concentration of exhaled carbon dioxide (CO2) gas in human breath called capnometer. CO2 being a very important biomarker, it is desirable to extend the scope of its monitoring beyond clinical use to home and ambulatory services. Currently the scope of capnometers and its adaption is limited by high cost, large size and high power consumption of conventional capnometers . In recent years, MEMS based micro resonant sensors have received considerable attention due to their potential as a platform for the development of many novel physical, chemical, and biological sensors with small size, low cost and low power requirements. The sensor is designed using 0.35 micron CMOS technology. CoventorWare and MATLAB have been used as simulation software. According to the developed model and simulation results the resonator has resonant frequency 57393 Hz and mass sensitivity of 3.2 Hz/ng. The results show that the longitudinal relative change of resistance is 0.24%/µm while the transverse relative change of resistance is -0.03%/µm.

Hydraulic support tester is the key equipment to measure the safety performance and technical performance of the hydraulic support. As an integral part of hydraulic support tester, synchronized loading system bears much load and eccentric load, needs high synchronization precision, and exits mechanical-hydraulic coupling. For these characteristics, building a synchronous loading system platform model, carrying on force analysis of the platform, and then getting four-cylinder pressure at different heights of the loading course are necessary. This research constructs a synchronous control circuit for hydraulic loading system using multi-physic modeling and simulation software—AMESim; simulation is carried out to optimize parameters of PID controllers in order to reduce the four-cylinder position synchronization error. As a conclusion, simulation results validate that appropriate solutions improve the precision and also demonstrate that the designed control system is suit for the synchronization control of the four-cylinder.
