Moving the dialysis treatment from the nephrology clinic to the patient's point of need, instead of moving patients to the nephrology clinic, is a great challenge today. The main objective of work presented in this the paper is the development of a universal system, suitable for European environment, for the management, control and monitoring of wearable and portable dialysis devices. The paper discusses its design and presents briefly the main components of the experimental Personal Health System, emphasizing also the main advantages of using such approach. The results of implementing a dialysis device simulator based on standard IEEE specification are also discussed. The system proposal is created based on collaboration among the University of Applied Sciences Munich, Germany, the University of Padova, Italy, and the University of Groningen, the Netherlands with participation of partner universities, hospitals and companies from Germany, Italy, and Romania.

In this work, a novel framework for optimal cooperative supervisory estimation of multi-agent linear time-invariant (LTI) systems is proposed which is applicable to a large class of multi-agent systems. This framework was recently developed by the authors based on the notion of sub-observers and a discrete-event system (DES) supervisory control. Each sub-observer estimates certain states that are conditioned on given inputs, outputs, and states information. Moreover, the cooperation among the sub-observers is managed by a DES supervisor. In this work, our proposed supervisory estimation framework is extended to the combinatorial optimization domain. When certain anomalies (faults) are present in the system, or the sensors and sub-observers become unreliable, the proposed optimal DES supervisor makes decisions regarding the selection and reconfiguration of sets of sub-observers to estimate all the system states, while simultaneously a performance index that incorporates the communication cost, computation cost, and reconfiguration cost, and the number of invalid state estimates is minimized. The application of our proposed methodology in a practical industrial process is demonstrated through numerical simulations.

In this paper, an approach to solve a flow assignment problem is proposed assuming known the whole trip planning of the fleets. The objective is to minimize both the risk of the network associated to the DG transport flow and the variance of the assigned delivery planning in respect to the expected one. Different simulation tests have been performed to evaluate the goodness of the proposed model, planning one or two deliveries from different OD pairs, varying risk values on the links of the network during the time horizon. The results demonstrates that model application guarantees a decrease of risk costs splitting flows on multiple paths avoiding to transit on links characterized by an high risk at a certain time, as well as the respect of expecting flow over each link.

This paper studies the current state of architecting practices in three different industrial segments which are characterized by being software-intensive. The context of the six different companies as well as the architecting practices are compared and analyzed. The methods used to solve the tasks within the architecting process are mapped to the context where it has been used in industry. An analysis of the case study indicates how different methods are more suitable in different environments. Many of the successful practices found in the study can be explained by external factors related to the context of the different companies. Others relate to the internal structure of the organization, including its maturity which is measured by assessment through an adaption of the Capability Maturity Model Integration (CMMI).

This paper presents a new approach to Model-Based Systems Engineering (MBSE) called “Attribute-Oriented Modeling.” This approach is used with a modeling language such as UML. The central concept of this approach is that model elements used in models of systems in a particular domain should be defined with a set of attributes that the system components to be modeled possess. The model of a system is created by specifying, for each component in the system, the values of the attributes that the model element that represents the component has.

Several agile methods were proposed that should provide more agility for Systems Engineering. But there was little discussion about the right context for Agile Systems Engineering. This paper shows under which conditions the main principle of agile development can be applied successfully. Therefore prior research about context of agile software development is reviewed. Additionally 20 system developing companies are being interviewed. A classification scheme that divides the context into feasibility and demand for agility is presented. Also contextual factors are listed to classify companies or projects within this scheme. Real company examples are demonstrated for the different situations in this scheme. And recommendations concerning agility are given.

In this paper, we describe the results of applying predictive software-dependent system engineering practices using the SAE International Architectural Analysis and Design Language (AADL) in the modeling and analysis of an unmanned aerial system (UAS), part of a search and rescue (SAR) system. The SAR system embodies many of the challenges associated with engineering complex software-dependent systems, such as achieving stringent performance requirements and ensuring effective resource utilization. The results of this work demonstrated that model-based software system engineering practices employing the AADL can be used to analyze important system aspects early in architectural development, and can be an integral element in making informed decisions throughout an engineering effort.

In order to meet the mission needs of today and keep up with the pace of technological advances, adapting the Enterprise Systems Engineering (ESE) process in a time constrained mission-centric environment is critical to leverage the efficient delivery of new capabilities in a Net Centric environment. Agility (contemporary) versus rigidity (traditional) are approaches that have their trade-offs but to meet the demands and needs of our war-fighters, we must have an ESE process that allows us to deliver quality capabilities to the tactical edge. Governance plays a significant role and testing services needs to be addressed different from the traditional T&E of stovepiped systems. The traditional approach of building systems to deliver a specific function is being changed to an approach of architecting services. ESE utilizes defined processes that use managerial and technical tools to analyze problems and provide structure to the overall process of planning, procuring, designing, implementing and testing an enterprise system. Adding agility and assurance to the traditional and ESE is the process by which we build quality into complex systems while delivering functionality and security of contents in a manageable timeframe and stay flexible to meet emerging requirements. This study is based on architecting the GIG which is the ultimate complex system. Utilizing the DoD's framework to facilitate information sharing; which starts with data discovery and access, we analyzed several concepts to achieve agility and higher level of security in Information Sharing Systems. The concept of the GIG also ensures that systems are not only robust but also incorporate the flexibility needed to satisfy needs that evolve during the system's life.

The main goal of Human Computer Interface (HCI) is to improve the interactions between users and computers by making computers more usable and receptive to the user's needs. Accordingly, surveillance is one of the major areas where human computer interface is critical. Surveillance cameras are usually controlled with joysticks. For this reason, it is almost impossible to be controlled by an amputee with no finger functionality. In this paper, the Fast Fourier Transform (FFT) analysis was applied to raw EMG data and then features are extracted with Principal Component Analysis (PCA) and Simple Principal Component Analysis (SPCA). In the proposed system, in order to make a decision whether the wrist is moving right, left, up, down or neutral, multi-class Support Vector Machine is employed. Additionally to Electromyography (EMG) signals, standard datasets that involves Electroencephalography (EEG) signals is also tested with multi-class SVM to verify the system robustness. Finally, classified EMG decisions are received by the camera as movement comments. Successful operation of camera employing EMG signals has been accomplished with 81% accuracy with SPCA.
