Iris pattern is a unique, stable and non-invasive biometric feature, suitable for individual recognition purposes. There are several and very diverse iris recognition algorithms, but in most cases, a collaborative environment and ideal conditions are required when capturing the system input image. To overcome these constraints and increase the number of domains in which iris recognition systems can be used, it is essential to develop robust algorithms that work in non-collaborative environments, but in order to do this in a correct way, it is important to previously analyse the different situations that can occur in such environments. In this context, different noisy and artificial iris images are analysed in this paper in order to determine its influence in iris recognition systems performance.

This paper presents a communications and software architecture in support of Prognosis and Health Monitoring (PHM) applications for renewable ocean-based power generation. The generator/turbine platform is instrumented with various sensors (e.g. vibration, temperature) that generate periodic measurements used to assess the current system health and to project its future performance. The power generator platform is anchored miles offshore and uses a pair of wireless data links for monitoring and control. Since the link is expected to be variable and unreliable, being subject to challenging environmental conditions, the main functions of the PHM system are performed on a computing system located on the surface platform. The PHM system architecture is implemented using web services technologies following MIMOSA OSA-CBM standards. To provide sufficient Quality of Service for mission-critical traffic, the communications system employs application-level queue management with semantic-based filtering for the XML PHM messages, combined with IP packet traffic control and link quality monitoring at the network layer.
本文提出了一种支持可再生海洋发电预测与健康监测(PHM)应用的通信和软件体系结构。发电机/涡轮机平台配备了各种传感器(例如振动、温度)，这些传感器产生周期性测量，用于评估当前系统的健康状况，并预测其未来的性能。发电机平台锚定在离岸数英里处，使用一对无线数据链进行监测和控制。由于连接可能是可变且不可靠的，并且会受到具有挑战性的环境条件的影响，因此PHM系统的主要功能在位于地面平台的计算系统上执行。PHM系统架构使用遵循MIMOSA sa - cbm标准的web服务技术实现。为了为关键任务流量提供足够的服务质量，通信系统采用应用程序级队列管理，对XML PHM消息进行基于语义的过滤，并结合IP数据包流量控制和网络层的链路质量监控。

This paper details a step toward introducing an electromechanical Functional Basis into the functional modeling stage of the systems engineering process. The Functional Basis proposed by Hirtz et al. gained visibility in the product design community, but it has had limited exposure in the systems engineering community. The purpose of this paper is to propose the addition of a functional modeling technique that uses this Functional Basis to the systems engineering process. The models proposed in this paper achieve a higher degree of detail earlier in the process than models created using classical system engineering methodologies, although those without prior exposure to this methodology found it difficult to use the functional model. The value of the proposed approach is demonstrated through an example case, verified based on stakeholder input through interviews.

This paper shows that the price of the kilo Watt hour can be used to level off daily peak demands of heat energy in district heating without compromising the end customer's comfort. A 5 days simulation of a building at an outdoor temperature of −15°C shows a 20% power consumption reduction causing only a 1°C variation of indoor temperature when the price is raised as a function of heat energy demand. This control scheme is made possible when using Internet communication between the heat supplier and the buildings' substation when the latter is equipped with a wireless sensor network to share internal information.

In widely distributed measurement systems, the first guess for the station measurement quality control is to compare the measurement to the neighbor stations. The basic degree of neighborness is often determined by the inverse distance of the measurement stations. However, this will not be descriptive in statistical sense if the system behind the observations is spatially complex or the sensors suffer from quality issues. This paper suggests a framework for measuring the statistical distance between stations within the system. The measures are developed with an assumption of large-scale observation systems, and therefore the computational and database access requirements are desired to keep as low as possible. The special emphasis of the numerical examples is on the meteorological measurements.

The increased popularity of the proactive security paradigm aggravated the need for pervasive surveillance systems. These systems are built using smart sensor networks which cover large areas of civilian concentration. Such networks need intelligent management systems to control the large number of sensor nodes and the large amount of data. Sensor Management Frameworks (SMF) aim to coordinate the sensor nodes in a manner that improves the process of system control and situation awareness. Large number of non-functional merits, i.e., autonomy, scalability, inter-operability, and others, can characterize SMFs. This paper proposes a taxonomy for these non-functional merits based on the design concepts. Furthermore, this paper discusses the important functional properties of such systems, and categorizes these functional properties according to their processing level. In addition, a scalable and adaptable control architecture that is applicable in a variety of sensor management applications with a focus on tactical surveillance is introduced. The proposed Holonic-Federated Sensor Management Framework (HF-SMF) mixes the advantages of the holonic and federated paradigms. Experimental results illustrate the performance of the proposed architecture and show that the proposed paradigm is highly scalable compared to the centralized one.

Renewable energy solutions are becoming increasingly popular. Photovoltaic (solar) systems are but one example. Maximizing power output from a solar system is desirable to increase efficiency. In order to maximize power output from solar panels, one needs to keep the panels aligned with the sun. As such, a means of tracking the sun is required. This is definitely a more cost effective solution than purchasing additional solar panels. It has been estimated that the yield from solar panels can be increased by 30 to 60 percent by utilizing a tracking system instead of a stationary array. In this paper, a prototype for a microcontroller-based multi-function solar tracking system is described, which will keep the solar panels aligned with the sun in order to maximize efficiency. The maximum power point tracking (MPPT) data can be transmitted in real time to other solar systems in need of this data.

Sensor data integration is crucial for the analysis and identification of environmental patterns. In this research project, publicly available datasets of environmental sensor data are integrated with Google Earth. Information on environmental patterns is identified, analyzed, and presented on the Web in response to user queries. This prototype demonstrates how sensor data can be integrated with Google Earth to enable the geographic and temporal context display of environmental data, with an interactive format, for users to analyze and identify environmental patterns in real-time.

Modern control methods are suitable for increasing production capabilities of industrial enterprises by employing information technologies, which are often used for modernization of industrial processes without the need of acquiring new equipment. Therefore, automation of the industrial lines is one of the most important directions of the technological progress, as it leads to improvement and modernization of industrial processes. The technological process of tellurium production includes a number of stages, which require automatic regulation of many parameters with a high degree of precision. In this work, we analyze and propose a unified concept of application of modern automation techniques that can be used to build a three-level hieratical control system intended for improving the quality of product.

This paper actualizes the concepts described in a companion paper subtitled “Essential Concepts.” Here the authors use those concepts in a methodology for investigating whether making purposeful changes in a postulated set of canonical forces will change the levels of both the Boardman-Sauser “differentiating characteristics” for systems of systems and, in turn, cooperation and operational performance in an operating human activity SoS—the U.S. Counterterrorism Enterprise. The methodology recreates a real-world case—the enterprise's response to the Christmas Day Bomber—in an agent-based, game theoretic model (n-player, iterated “Stag Hunt”).
