The use of microsatellites for remote sensing missions is becoming more attractive. The cost-reliability issue is still a constraint. In this work we present a methodology for the development of Fault Tolerant Space Systems (FTSS) focusing on the On Board Data Handling (OBDH) system for microsatellite's remote sensing payloads with COTS components. The methodology presented is based on Fault Tolerance Techniques applied to Field Programmable Gate Arrays. The proposed methodology ends with a guideline for simulating the system reliability, providing statistics to support decisions regarding the necessary techniques to be implemented.

Wireless sensor network technologies can be used for industrial embedded system design to save cabling cost and weight. However, their environment, architecture, and design issues are quite different from original sensor network applications. Simulation tools and system design environments have to be adapted to the special requirements, such as operational modes and phases which influence the system. This paper presents a more detailed wireless sensor network to check against the application requirements concerning QoS, reliability, and lifetime. An avionics application example is presented.

Soldiers know firsthand the criticality of having mission essential supplies and equipment arrive at the right place, at the right time. This is of particular importance when operating in remote locations around the world where hostilities are prevalent, terrain is restrictive and mission accomplishment has strategic implications. The Joint Precision Airdrop System (JPADS) is a guided logistical resupply platform that delivers supplies and equipment in a precise manner to Soldiers operating in restrictive or hostile terrain from a high altitude when conventional means of resupply are unavailable, unrealistic or ill-advised. Our current force structure requires a system that can operate in a dynamic and mercurial environment in order to rapidly adjust to changes on the ground. The research paper will explore the JPADS from a Systems Architecture perspective in order to decompose the system and provide critical system details, which will aid in the Design Structure Matrix (DSM) analysis that will follow. The outcome of this research is to not only provide recommendations to the project sponsors working on the JPADS, but to illustrate the value of using Systems Engineering methodologies and tools to analyze complex systems and challenges.

To become interaction-aware, an autonomic cyber-physical system needs to be aware of its physical environment and whereabouts and its current internal status. This ability is defined as artificial awareness and it helps intelligent software-intensive systems perceive changes, draw inferences for their own behavior and react. Originally, artificial awareness depends on the knowledge we transfer to a system and how we make the system use that knowledge, so it can exhibit intelligence. Artificial awareness requires a means of sensing changes, so the external and internal worlds can be perceived through their raw events and data. To build an efficient awareness mechanism, we need to provide a means of monitoring and knowledge representation along with a proper reasoner deriving awareness conclusions. In this paper, we present an approach to implementing artificial awareness with KnowLang, a special framework for knowledge representation and reasoning. KnowLang provides for a special knowledge context and a special reasoner operating in that context. The reasoner communicates with the host system via special ASK and TELL operators allowing for awareness conclusions and updates.

Current management of enterprises is fragmented and stovepiped, leading to misalignment of resources and less effective decision-making. From previous research and exploration of the work of A. Angyal, we identified 4 dimensions relevant to informing a coherent view of an enterprise. This paper presents a proposition that if managers consciously consider these 4 dimensions of the enterprise, they will develop a shared model rich enough to understand it so that they can regulate it appropriately, whilst at the same time enable it to react and adapt successfully in a challenging and changing environment. We also suggest these dimensions are useful guides to the selection of multiple systems methods to inform thinking appropriately.

Early system engineering is not focused on the natural triangle of relationships between architecture, alternatives and performance. As a result, early understanding of conceptual trade space is focused on a sequential and independent effort when developing the system concept. This method is rife with inefficiency, broad and incorrect assumptions of the preceding step, ultimately leading to large amounts of rework and a non-unifying effort throughout the project team. This paper provides a means to show through an illustrative example that these three elements are interconnected and building them simultaneously improves the efficiency of concept development. The results of the paper highlight the parallel relationships between the elements that are usually developed in a serial process. This method provides the means to continuously build related architecture, alternatives, and performance elements together.

We are developing a web based application for use by diabetes patients to manage their chronic condition. The application will allow patients to keep abreast of the latest developments as pertinent to their specific condition (type, risk factors, medication, history, preferences, etc.), interact with others in a community of users, and have more effective dialog with their health care providers. This paper will document our recent developmental efforts to incorporate semantic web concepts and health information technology infrastructure.

Modern software frameworks for Model-Based Systems Engineering (MBSE) methodologies are proprietary and commonly restricts to a poor choice of domain specific languages. Furthermore, the interoperablity and model interchange support between frameworks is a technically hard challenge. The industrial strength standard OMG MOF (Meta-Object Facility) is a solid approach for the definition of domain specific languages. Applying meta-modeling techniques to existing modeling and simulation frameworks reduces obscurity of proprietarity and implicitely language characteristics. On the other hand, standard compliance improves product openness/transparency, reliability and confidence as for primary modes of operation. This paper presents a methodology to incorporate methods of meta-modeling and standard compliant domain specific languages in an existing modeling and simulation framework. First results are emerged and exemplified for an effective modeling dialect called MML (MLDesigner Modeling Language). Future prospects reviews already accomplished goals in this project, address several alternatives and improvements and gives an overview of ongoing development.

This paper proposes an embedded system development process capable to deal with affectivity requirements. It is supported by W3C tools, such as EmotionML and SysML. These tools should be used to specify cognition and affectivity as system requirements. The proposed process is based on three different integration models: Sparx's [1], Wolf's System Development Process [4] and Russell's Intelligent Agent Specification [5]. In order to validate this proposal a pet robot case study has been built. This application can be useful in many non-critical domestic applications, such as assistive robots for capturing attention of autistic children and robot therapy for elders. Moreover, it represents a futuristic embedded system design space for applying affective computing.

The U.S. Defense acquisition system is notoriously resistant to fundamental reform and improvement. This case study examines the fundamental change in the technical architecture of the Navy's submarine sonar system and its acquisition enterprise. Many studies and recommendations for acquisition reform focus on process and incentive structures, few focus on architecture. Rather than focus on process, this case study focuses on the inter- and intra-organizational relationships, the larger scale social and bureaucratic dynamics and the technical architecture. We find that the technical architecture changed from tightly integrated hardware/software architecture to a layered architecture. Layering enabled a spiral development process able to match system upgrades to commercial technology rates of change. We also find a layered enterprise architecture, where different organizations were connected at different hierarchical levels. This enabled fleet operators to provide unfiltered feedback to development engineers, mid-level managers to coordinate priorities and key decisions and senior leadership to provide consistent strategic guidance to the system.
