A summary of the class's objectives, content, system of systems-based projects and use in assessment are presented for the past three years. The course has evolved from that reported previously where it was centered on mobile robots, sensing and coordinated behavior to its current incarnation that focuses on the design of beacon-finding mobile robots. Beacon-finding robots are the result of the evolution of the course and desire to have students address projects with design and integration of multiple, independent systems. Students are tasked to build an autonomous mobile robot that can detect a Radio Frequency (RF) beacon, and ultimately use the robot's location and measurements from the beacon to determine the beacon's location without necessarily driving to it. The project blends several technical areas of electrical electrical engineering that include electromagnetics, RF, control theory, analog and digital electronics, signal processing, programming, and microcontrollers along with broader skills related to communication and design.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117286077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Focus is then turned to the spectrum of challenges faced for deployment of CSG. Finally, a path forward to addressing these challenges is explored. The paper concludes with several contributions that CSG can offer to SoSE in the struggle to deal with increasingly complex systems and their associated problems.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124472952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sheer number of decision variables that need to be considered in SoS development prompts the need for effective analytical support frameworks. Current frameworks and guidelines in addressing SoS challenges lack analytical means of objective SoS level decision-making. Research in this paper adopts computational decision methods rooted in financial risk management that allow SoS practitioners the means to identify optimal `portfolios' of systems based on dimensions of capability, cost and operational risk. Many risk management processes are in place for individual systems, but these tools and techniques are not always compatible for SoS. Our research leverages a Conditional Value-at-Risk (CVaR) perspective to managing risks that can incorporate simulation/observed data in the decision-making process. We demonstrate the method using a simple SoSE problem.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124743779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study of Human Factors is a broad domain with equally varying applications. Quantification thereof, with a Human Reliability Analysis (HRA) poses considerable challenges and advantages. In increasingly complex modern systems where large resources are allocated towards ensuring system's operational safety, it becomes necessary to analyze the actions of human operator who directly or indirectly influences system reliability. This paper envisages establishing a base towards a HRA model, to address existing issues. Railway systems and Advanced Driver Assistance Systems for automobiles are our application domains; we aim to identify the need of and usability in both. Human considered as a component of the System of Systems for risk assessment allows us to study its impact on system reliability and give feedback to improve system safety.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128744378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to protect these interests, governments require capabilities that provide situational awareness of the maritime domain. In [11] a spatiotemporal analysis approach is proposed that autonomously analyzes and classifies ship movement and possible intent at sea. The analysis focuses on detection of vessels of interest that exhibit one behavior, paralleling or following behavior. In this paper, we extend this approach by proposing a generalized semantic method that enables consideration of other behaviors of interest. Additionally we conduct a series of simulations using simulated and real AIS data to assess the performance of the algorithm to variation in behavior thresholds.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"295 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128635164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such a polymorph approach to system architectures requires novel specification techniques. A system-of-systems conceptualization enables addressing emergent behavior, while letting the involved components and systems operate independently of each other. This property requires system interoperability and can be achieved by bigraph-based modeling. A flexible abstraction mechanism as well as a strong typing of system interaction enable system interoperability in evolutionary environments. Consequently, the composition and decomposition of bigraph-based models support the emergence of novel behavior. We evaluate the potential of this approach based on its capability to represent system-of-systems according to the distinguishing characteristics proposed by Boardman and Sauser as well as by orchestrating two independent systems.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114152015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For applications wherein GNSS-only navigation may prove challenging the inclusion of an INS offers reliable position, velocity, and attitude (PVA) determination. Unfortunately, all INS suffer from drift due to inherent sensor errors. Consequently, aiding sensors must be employed to bound this drift. In this paper we present a proof-of-concept of leveraging a collection of communication systems to provide an INS aiding source. In particular, orthogonal frequency division multiplexing (OFDM) signals will be explored as they are a ubiquitous communication standard. Specifically, the paper investigates the use of Doppler shift measurements via software defined radios followed by a simulation, in order to examine the efficacy of the proposed system.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121806676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, no single group has solved the problem of making robots that will perform a set of tasks sufficient enough to warrant the cost to the end consumer. Numerous advances and improvements in computing, communication and related robotic technologies have been paving the way towards cheaper, more capable robots. We propose a home robot system consisting of a set of heterogeneous robots with different task spaces, cloud computing to enhance the abilities of the system, integration with existing home infrastructure, and compatibility with mobile technology. A high level of integration with the open source software of the Robot Operating System (ROS) is proposed to accelerate the design process. For the exact types of robots, we propose to use an enhanced floor cleaning robot and a mobility and vision assistance robot in the form of an improved rollator walker.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134094655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
