This paper uses the concept of metasystem and system of system (SOS) to assist in the governance of several networked systems. The approach used here is to consider a metasystem as a controller that can enable and order a set of systems interfaces according to the expected behavior. We use Langefors theory and Finite State Processes to formalize a metasystem architecture and finally we show how the concept can be used for a specific case using an authentication and authorization protocol to manage dispersed systems.

The FM (Frame Manager) flight software module is responsible for maintaining the frame tree database containing coordinate transforms between frames. The frame tree is a proper tree structure of directed links, consisting of surface and rover subtrees. Actual frame transforms are updated by their owner. FM updates site and saved frames for the surface tree. As the rover drives to a new area, a new site frame with an incremented site index can be created. Several clients including ARM and RSM (Remote Sensing Mast) update their related rover frames that they own. Through the onboard centralized FM frame tree database, client modules can query transforms between any two frames. Important applications include target image pointing for RSM-mounted cameras and frame-referenced arm moves. The use of frame tree eliminates cumbersome, error-prone calculations of coordinate entries for commands and thus simplifies flight operations significantly.
FM (Frame Manager)飞行软件模块负责维护包含帧间坐标变换的帧树数据库。框架树是一种正确的有向链路树结构，由表面子树和漫游子树组成。实际的帧变换由其所有者更新。FM更新站点并为表面树保存帧。当漫游车行驶到一个新的区域时，可以创建一个具有增量站点索引的新站点框架。包括ARM和RSM(遥感桅杆)在内的一些客户更新他们拥有的相关漫游者框架。通过板载集中式FM帧树数据库，客户端模块可以查询任意两帧之间的转换。重要的应用包括rsm相机的目标图像指向和框架参考臂移动。框架树的使用消除了繁琐的、容易出错的指令坐标条目计算，从而大大简化了飞行操作。

A system of systems modeling approach can be used to plan and guide implementation of economic revitalization efforts. A key metric of success is the improved outcomes of individuals in terms of standard of living and subjective well-being. Initial results for a latent variable model based on national survey data show a moderate correlation between subjective well-being and objective measures of standard of living, and good fit for a three-factor model that relates economic, security, and social network variables to human capital. Human capital is a production system within the economy; it is equipped and maintained by the education and healthcare systems of the region. This perspective is useful in analyzing and evaluating the system of systems that comprise a regional economy.

This paper applies results from studies of the acquisition process and from algorithmic methods applicable to the mechanism design of agent-based auctions to modeling behaviors and effecting policy interventions that are intended to improve overall programmatic performance when acquiring independently managed systems of systems. Previous models and empirical studies provide an understanding of the behavioral aspects of the acquisition process and are supported by empirical data from surveys. A method inspired by mechanism design is proposed that incorporates the insights and data from these studies to formulate a probabilistic optimization framework for constructing interventions that enhance the probability of meeting cost and schedule goals when acquiring a system of systems.

System of systems (SoS) and System of Systems Engineering (SOSE) are made up of independent autonomous system. SoS has used a number of concepts from complexity theory, such as inclusion of autonomous and independent systems and emergence. However, there are a number of other concepts that have not been so readily used in SoSE which have been clearly enunciated in complex systems research papers. These include self organization, complexity leadership, stability levels and notions of being on the edge of chaos, phase history and initial conditions, co-evolution, hierarchy versus networked, and redundant resources. These concepts are examined and some implications for use in SoSE proposed. Although it is considered desirable to include these in SoSE architecture, it is concluded that SoSE architecture is not adequately developed so inclusion in processes to be used in SoSE architecture is the best approach.

One of the actual problems in product lifecycle management (PLM) is consideration of requirements from various systems. While a PLM system is focused on object interactions within a product, engineering for a product system requires interaction with other systems. This experience motivates research in integration of System of Systems (SoS) and PLM methodologies. In order to do the next step to include SoS specific features in the product model, this paper introduces a shift of PLM input interactions for product definition to the level of knowledge supported product functions. Application of the feature principle in product model construction helps the connection of systems.

The need for rapid development of tactical system of systems solutions for military applications requires the use of system modeling techniques and simulation and validation methods to be applied throughout the lifecycle of the system. This combined approach of development and verification is preferred to traditional approaches for risk mitigation and cost effectiveness. This paper examines the Integrated Blast Effects Sensor Suite developed at the Georgia Tech Research Institute and its architecture as a complex system of systems.

The design methodologies of using sequence diagrams, multi-process functional flow diagrams, and hierarchical state machines were successfully applied in designing three MSL (Mars Science Laboratory) flight software modules responsible for handling actuator motions of the CHIMRA (Collection and Handling for In situ Martian Rock Analysis), IC (Inlet Covers), and DRT (Dust Removal Tool) mechanisms. The methodologies were essential to specify complex interactions with other modules, support concurrent foreground and background motions, and handle various fault protections. Studying task scenarios with multi-process functional flow diagrams yielded great insight to overall design perspectives. Since the three modules require three different levels of background motion support, the methodologies presented in this paper provide an excellent comparison. All three modules are fully operational in flight.

Cloud computing is the current IT buzzword synonymous with outsourced data center management and agile solution architecture. It has the potential to improve scalability of large enterprise network delivery of services and the capability to revolutionize how data is delivered as a service. At its core, cloud computing is not a new technology but rather a new approach of distributed shared pooling of IT infrastructure linked together to offer centralized IT services on demand. The study results determined that management's perception of security, cost-effectiveness and IT compliance factors significantly influence their decisions to adopt cloud computing. The results of multiple linear regression analysis testing in this study showed that management's perception of cost-effectiveness is more significantly correlated to their decision to adopt cloud computing than security.

Random walk (RW) routing for Wireless Sensor Networks (WSNs) has been proven to balance energy consumption for the whole sensors. Since Compressive sensing (CS) provides a novel idea that can reconstruct all raw data based on a small number of measurements, the energy consumption for data gathering in WSNs is reduced significantly. The combination between RW routing and CS can help efficiently save energy and achieve longer network lifetime. In this paper, we continue to introduce RW as an effective routing method in WSNs utilizing CS. We formulate the mean value of the communication distance between sensors in a RW and the mean distance between RWs and the base station (BS) statistically. We finally build the total energy consumption and exploit the minimum energy consumption case for the network. Based on analyzing the sensor broadcasting radius, while the WSN is connected as an undirected graph G(V, E), we can suggest the optimal radius that leads the network consumes the least energy and even has load balancing.
