    Scalability of Copper-Interconnects down to 3μm on Printed Boards by Laser-assisted-subtractive process2019In: Proceedings of: 2019 IMAPS Nordic Conference on Microelectronics Packaging (NordPac), IEEE, 2019, p. 206-209Conference paper (Refereed)
    Abstract [en]

    As per the latest roadmap of iNEMI, the global electronics market is emphasizing to identify disruptive technologies that can contribute towards denser, robust and tighter integration on the board level. Therefore, reduction in packaging factor of printed board can accommodate greater number of ICs to support miniaturization. This paper has shown an experimental method to pattern the metallic layer on a Printed circuit Board (PCB) to the smallest feature size. To investigate this, a commercially available FR-4 PCB with photosensitive material coat and a Copper (Cu) layer on it, is used. A reverse-mode Laser assisted writing is implemented to pattern the desired copper tracks. Soon after, a well-controlled development and chemical etching of the Laser-activated regions are done using Sodium Hydroxide solution followed by an aqueous solution of Sodium Persulfate. Current PCB interconnects used by the industries are of the order (~20 μm). Whereas the present work is a contribution towards achieving Copper interconnects with feature size 3.0μm. This miniaturization corresponds to 70% reduction in the feature size from 20 μm to 3μm. The natural adhesion of the Cu layer has remained intact even after the etching, shows the efficiency of the method adopted. Also, variation in the parameters such as etching time, etchant solution concentrations, temaperature, gain and exposure time of Laser beam and their corresponding effects are discussed. Other highlights of this subtractive method includes its cost-efficiency, lesser production time and repeatability.

    Estimating material properties of solid and hollow fibers in suspension using ultrasonic attenuation2013In: IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, ISSN 0885-3010, E-ISSN 1525-8955, Vol. 60, no 7, p. 1424-1434Article in journal (Refereed)
    Abstract [en]

    Estimates of the material properties of hollow fibers suspended in a fluid using ultrasound measurements and a simple, computationally efficient analytical model are made. The industrial application is to evaluate the properties of wood fibers in paper pulp. The necessity of using a layered cylindrical model (LCM) as opposed to a solid cylindrical model (SCM) for modeling ultrasound attenuation in a suspension of hollow fibers is evaluated. The two models are described and used to solve the inverse problem of estimating material properties from attenuation in suspensions of solid and hollow polyester fibers. The results show that the measured attenuation of hollow fibers differs from that of solid fibers. Elastic properties estimates using LCM with hollow-fiber suspension measurements are similar to those using SCM with solid-fiber suspension measurements and compare well to block polyester values for elastic moduli. However, using the SCM with the hollow-fiber suspension did not produce realistic estimations. In conclusion, the LCM gives reasonable estimations of hollow fiber properties and the SCM is not sufficiently complex to model hollow fibers. The results also indicate that the use of a distributed radius in the model is important in estimating material properties from fiber suspensions.

    Quality of Service on the Arrowhead Framework2017In: 2017 IEEE 13th International Workshop on Factory Communication Systems (WFCS), Piscataway, NJ: Institute of Electrical and Electronics Engineers (IEEE), 2017, article id 7991959Conference paper (Refereed)
    Abstract [en]

    Quality of Service (QoS) is an important enabler for communication in industrial environments. The Arrowhead Framework was created to support local cloud functionalities for automation applications by means of a Service Oriented Architecture. To this aim, the framework offers a number of services that ease application development, among them the QoSSetup and the Monitor services, the first used to verify and configure QoS in the local cloud, and the second for online monitoring of QoS. This paper describes how the QoSSetup and Monitor services are provided in a Arrowhead-compliant System of Systems, detailing both the principles and algorithms employed, and how the services are implemented. Experimental results are provided, from a demonstrator built over a real-time Ethernet network.

    Ultrasonic flow metering errors due to pulsating flow2004In: Flow Measurement and Instrumentation, ISSN 0955-5986, E-ISSN 1873-6998, Vol. 15, no 3, p. 179-185Article in journal (Refereed)
    Abstract [en]

    Transit-time ultrasonic flow meters present some advantages over other flow meters for district heating industries. They are both accurate and non-intrusive. It is well-known that ultrasonic flow meters are sensitive to installation effects. Installation effects could be static or dynamic. Among the possible dynamic installation effects is pulsating flow. The influence of pulsating flow on the prediction and the zero-crossing operations is investigated. Expressions are found for the prediction error and the zero-crossing error. The relative errors due to the prediction and the zero-crossing are plotted. The prediction error can reach dramatic values while the zero-crossing operation is hardly influenced by flow pulsations.

    Detection of pulsating flows in an ultrasonic flow meter2002In: Proceedings of the 8th International Symposium on District Heating and Cooling, 2002Conference paper (Refereed)
    Abstract [en]

    Transit-time ultrasonic flowmeters present advantages for district heating applications, since they are accurate, non-intrusive, and cheap. However, such flowmeters are sensitive to velocity profile variations since the flow rate is measured in the volume area between two ultrasonic transducers. Ultrasonic flowmeters are therefore sensitive to installation effects. Installation effects could be either static or dynamic. A pulsating flow is a dynamic installation effect. In the field, the diagnostic can only be performed with the measured flow rate. Flow measurements with and without pulsating flow have been recorded in a flow meter calibration facility. The detection of a pulsating flow can be made by using Hinich's harmogram. It is possible to detect harmonics that emerge from the noise by using the harmogram.

    Detection of the error generated by a single elbow on an ultrasonic flow meter2002In: ISA TECH/EXPO Technology Update Conference Proceedings: ETCON 2002, ISA - Instrumentation, Systems, and Automation Society , 2002, Vol. v 426 II, p. 1268-1279Conference paper (Refereed)
    Abstract [en]

    Ultrasonic flow meters are accurate and non-intrusive. However, one of their drawbacks is their sensitivity to installation effects especially when elbows or pulsating flows are found in front of the meter's inlet. Depending on the flow rate, such installations can create perturbations on the flow measurement. These perturbations cause an increase of the noise level as well as a possible error on the flow estimation. A technique using the noise level as a criterion for making a diagnostic of the error is presented. The perturbations are examined and compared to gaussian distributed signals. A basic method for detecting gaussian perturbations with equal means is described. The likelihood ratio is first computed in the general case. It is also computed making the assumption of uncorrelated signals. Receiver Operating Characteristics (R.O.C.) are plotted. The assumption of gaussian perturbations is then investigated. Optimal thresholds are proposed for both methods and for a large interval of flow rates (from 0.4 ml/s to 0,75 1/s). Probabilities of detection and of false alarm are evaluated for both methods. It is concluded that correct detection can be performed. The optimal threshold is to be chosen by the operator.

    Reducing the flow measurement error caused by pulsations in flows2004In: Flow Measurement and Instrumentation, ISSN 0955-5986, E-ISSN 1873-6998, no 5-6, p. 311-315Article in journal (Refereed)
    Abstract [en]

    Different types of errors are generated by pulsations in flows. Among these errors is the sampling error due to a unadapted time-averaging of the flow rate. An improved model for pulsations in flows including harmonics is derived. The localization of the harmonics is performed by a detector. The period of the pulsations is estimated. It is then possible to reduce the sampling error by performing a correct averaging. The reduction of the sampling error is confirmed by simulations.

    Interacting with the arrowhead local cloud: On-boarding procedure2018Conference paper (Refereed)
    Abstract [en]

    Industrial automation systems are advancing rapidly and a wide range of standards, communication protocols and platforms supporting the integration of devices are introduced. It is therefore necessary to design and build appropriate tools and frameworks that allow the integration of devices with multiple systems and services. In this work we present the Arrow-head Framework, used to enable collaborative IoT automation and introduce two support core systems, SystemRegistry and DeviceRegistry, which are needed to create a chain of trust from a hardware device to a software system and its associated services. Furthermore, we propose an on-boarding procedure of a new device interacting with the Arrowhead local cloud. This ensures that only valid and authorized devices can host software systems within an Arrowhead local cloud.

    Towards Trustworthy End-to-End Communication in Industry 4.02017In: Proceedings: 2017 IEEE 15th International Conference on Industrial Informatics, INDIN 2017, Piscataway, NJ: Institute of Electrical and Electronics Engineers (IEEE), 2017, p. 889-896, article id 8104889Conference paper (Refereed)
    Abstract [en]

    Industry 4.0 considers integration of IT and control systems with physical objects, software, sensors and connectivity in order to optimize manufacturing processes. It provides advanced functionalities in control and communication for an infrastructure that handles multiple tasks in various locations automatically. Automatic actions require information from trustworthy sources. Thus, this work is focused on how to ensure trustworthy communication from the edge devices to the backend infrastructure. We derive a meta-model based on RAMI 4.0, which is used to describe an end-to-end communication use case for an Industry 4.0 application scenario and to identify dependabilities in case of security challenges. Furthermore, we evaluate secure messaging protocols and the integration of Trusted Platform Module (TPM) as a root of trust for dataexchange. We define a set of representative measurable indicator points based on existing standards and use them for automated dependability detection within the whole system.

    Monitoring Industry 4.0 applications for security and safety standard compliance2018Conference paper (Refereed)
    Abstract [en]

    In Industry 4.0 independent entities shall inter-operate to allow flexible and customized production. To assure the parties that individual components are secured to inter-operate, we investigate automated standard compliance. The standard compliance is defined based on given sets of security and safety requirements from which are derived measurable indicator points. Those reflect configurations of systems recommended by security, safety or legally relevant standards and guidelines, which help to demonstrate the state of compliance. We propose in this paper an initial approach to automate such assessment when components are inter-operating with each other by using a monitoring and standard compliance verification framework. This will assure the parties that services or devices within their organizations operate in a secure and standard compliant way, without compromising the underlying infrastructure.

    Reciprocal operation of ultrasonic transducers: experimental results2006In: Proceedings: 2006 IEEE Ultrasonics Symposium : Vancouver, Canada, 3 - 6 October 2006, Piscataway, NJ: IEEE Communications Society, 2006, p. 1013-1016Conference paper (Refereed)
    Abstract [en]

    Ultrasonic transit-time flow-meters estimate fluid or gas flows from the difference in times of flight of upstream and downstream acoustic pulses. However, any delay differences arising from sources other than the flow to be measured will cause a troublesome "zero flow" offset error.In theory, the transducers used in the measurement system should not influence the zero flow error, as electroacoustic systems based on piezoelectric transducers have been shown to be reciprocal (when the media is stationary). However, care is required when designing the electrical interfaces for the piezoelectric transducers, if reciprocity in the system is to be utilized.This work presents technique and measurements that apply reciprocity to an ultrasonic transit-time flow-meter. Specialized electrical transducer interfaces with options to drive the transducers from either low or high impedance sources were used. Combined with a high-impedance receive mode these options made it possible to change the conditions for reciprocity in the system.We show reduced delay difference in 9 cases out of 10 when trying to utilize the reciprocal property compared to when we disregard it in favor for larger excitation energy. The delay improvements were accompanied by reduced differences between the center frequencies of the signals from the two paths.

    Installation effects on an ultrasonic flow meter with implications for self diagnostics2000In: Flow Measurement and Instrumentation, ISSN 0955-5986, E-ISSN 1873-6998, Vol. 11, no 2, p. 109-122Article in journal (Refereed)
    Abstract [en]

    A small ultrasonic flow meter for water was exposed to five different test configurations, a reference experiment, a single elbow, a double elbow out of plane, a reduction in pipe diameter and a pulsating flow experiment. All tests were performed in a flow calibration facility ranging over Reynolds number from 25 to 110 000. The experiments with the four installation effects were compared with a reference experiment. The error and the change in standard deviation compared to the reference experiment were calculated. The standard deviation serve as a measure of the noise level of the flow meter. The results show that all disturbances generated errors in the flow measurement. The maximum errors were mainly in the range of 2–4% of flow rate, but at very low flow rates the pulsating flow caused larger errors. In most of the flow range there were no or smaller errors. All installation effects also generated an increase in the noise level. The different pipe configurations increased the standard deviation up to more than 100%. The pulsating flow induced even higher enlargements in the noise level. The errors and the increase in the standard deviation are present in about the same flow ranges. The results demonstrate not only that the installation effects tested introduce errors in the flow measurements but also that these effects can be detected from the noise level in the data. The noise level was determined from the standard deviation. This could be interpreted as that the disturbances amplify the turbulence intensity. Thus the standard deviation can be used as a measure of the turbulence. The presence of a disturbance could be recognised by comparing the magnitude of the noise level in the present data with a reference level valid for the measured flow rate. A procedure like this could possibly be performed by the meter itself in operation.

    Temperature and installation effects on small commercial ultrasonic flow meters2000Conference paper (Refereed)
    Abstract [en]

    Experimental work has been performed on a selection of small ultrasonic flow meters for water. This work was accomplished in order to investigate the in fluence of temperature and flow profile disturbances on the performance of flow meters in district heating applications. The flow meters tested were all ultrasonic flow meters of sing-around type. The selection of flow meters contains in total seven meters of three different brands. All meters have a flow range from 0.015 m3/h to 1.5 m3/h. These meters are commonly used in heat meters in small district heating subscriber stations. The flow meters are presented without identification. All tests were performed in a flow meter calibration facility and in a flow range including the minimum and maximum flow of each flow meter. In the tests three different water tempera-tures and three different installations were investigated. Water temperatures of 20 °C, 50 °C and 70 °C were used. These temperatures are representative for district heating applications. The installations tested involved flow meters mounted with long straight pipes both up-and down-stream representing ideal conditions, a single elbow and a double elbow out of plane both generating disturbed flow profiles. All set-ups are in accordance with the flow meter specifications. The results demonstrate that both the change in temperature and the disturbed flow profiles introduce errors in the flow measurements. The change from 20 °C to 50 °C and 70 °C can cause a shift in meter performance larger than the specified maximum permissible error. Compared with the ideal installation the installations generating disturbed flow profiles cause errors up to more than 2 %. The errors due to temperature and installation effects have a bias to add when combined. This might lead to even larger errors.

    Migration of industrial process control systems to service-oriented architectures2018In: International journal of computer integrated manufacturing (Print), ISSN 0951-192X, E-ISSN 1362-3052, Vol. 31, no 2, p. 175-198Article in journal (Refereed)
    Abstract [en]

    The use of Service Oriented Architectures (SOAs) in industrial automation promises an improved cross-layer integration as well as a functionality decoupled from the technical implementation. Compared with the earlier investigated manufacturing industry, control systems in the process industry reveal additional challenges in terms of migration from a legacy control system to an SOA control system.

    The successful migration of a highly integrated process control system, without reducing reliability or availability and, at the same time, preserving functionality and productivity, requires a detailed plan and certain specialised technology.

    This paper presents the challenges in the migration of a process control system and proposes a structured method for migration. The migration procedure proposed comprises four steps: initiation, configuration, data processing, and control execution. A technology demonstration at a pelletizing plant illustrates how the first of these steps could be implemented.

    Tackling current challenges in production automation requiresthe involvement of new concepts like Internet of Things,System-of-Systems and local automation clouds.The objective of this paper is to address the actual process of defining a cloud based automation system. More specifically the design, engineering, operation and maintenance of an automation system must be captured and managed between all stakeholders involved. This is critical to create the expected benefits from the local automation cloud approach.This paper addresses the capability of capturing plant designs and coordinating information exchange based on the captured architecture.For this purpose an architectural component --~Plant Description~-- is proposed to be used in the Arrowhead Framework, based on already existing plant automation standards.An overview of methodologies on how it can interact with the Arrowhead Framework's Orchestration process describes the usefulness in managing large-scale automation systems.A qualitative evaluation for one of the proposed approaches is also described in a water control use case that can be found both in process and building automation.

    Configuration Service in Cloud based Automation Systems2016In: IECON Proceedings (Industrial Electronics Conference), Piscataway, NJ: IEEE Computer Society, 2016, p. 5238-5245, article id 7793489Conference paper (Refereed)
    Abstract [en]

    Current challenges in production automation requires the involvement of new technologies like Internet of Things (IoT), Systems of Systems and local automation clouds. The objective of this paper is to address one of the challenges involved in establishing and managing a cloud based automation system. Three key capabilities have been identified as required to create the expected benefits of local automation clouds; 1) capturing of plant design 2) capturing and distributing configuration and deployment information 3) coordinating information exchange.

    This paper addresses the capturing and distribution of configuration and deployment information. For this purpose a system service is proposed, the ConfigurationStore, following the principles of the Arrowhead Framework. The service is accompanied by a deployment methodology and a bootstrapping procedure. These are discussed for several types of automation technology, e.g. controllers, sensors, actuators. A qualitative evaluation of the proposed approach is made for four use cases; Building automation, Manufacturing automation, Process automation and IoT devices. Concluding the usability for large-scale deployment and configuration of Industrial Internet of Things.

    Plant descriptions for engineering tool interoperability2017In: IEEE International Conference on Industrial Informatics (INDIN), Piscataway, NJ: Institute of Electrical and Electronics Engineers (IEEE), 2017, p. 730-735, article id 7819255Conference paper (Refereed)
    Abstract [en]

    The emergence and deployment of connected devices in many domains of application (e.g. industrial production, buildings and facilities, urban environment, etc.) have resulted in the need to achieve integration of multiple and more complex systems. This new environment is stressing the intrinsic limits imposed by monolithic standards, data models and integration methods that focus on specific domains of application, types of systems, or specific aspects of a system. This paper describes the Plant Description Service developed as part of the Arrowhead Interoperability framework (EU ECSEL funded project). The manuscript contains a description of the abstract system descriptive model based on which the Plant Description service was implemented, and describes how the service can be used to achieve integration of several industry standards and data models. One use case and one case study is provided that illustrates how the service was practically implemented to support engineering scenarios in the domain of industrial production. The paper concludes with a critical review of the approach and suggestion for future work and developments.

    A Configurable Cloud-Based Testing Infrastructure for Interoperable Distributed Automation Systems2015In: IECON 2014: 40th Annual Conference of the IEEE Industrial Electronics Society, Dallas, TX, USA , Oct. 29 2014-Nov. 1 2014, Piscataway, NJ: IEEE Communications Society, 2015, p. 2492-2498Conference paper (Refereed)
    Abstract [en]

    The interoperability between various automation systems is considered as one of the major character of future automation systems. Service-oriented Architecture is a possible interoperability enabler between legacy and future automation systems. In order to prove the interoperability between those systems, a verification framework is essential. This paper proposes a configurable cloud-based validation environment for interoperability tests between various distributed automation systems. The testing framework is implemented in a multi-layer structure which provides automated closed-loop testing from the protocol level to the system level. The testing infrastructure is also capable for simulating automation systems as well as wireless sensor networks in the cloud. Test cases could be automatically generated and executed by the framework.

    A new velocity algorithm for sing-around-type flow meters1987In: IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, ISSN 0885-3010, E-ISSN 1525-8955, Vol. 34, no 4, p. 431-436Article in journal (Refereed)
    Abstract [en]

    In many flow metering applications the fluid temperature can change rapidly during the measurements. An example is flow metering in district heating systems. These temperature changes will cause fast, large changes of the speed of sound in the fluid. If not recognized, this phenomenon can introduce severe errors in sing-around-type flow meters. The sing-around flow meters used today handle this problem with varying success. Therefore, the algorithm used to calculate the flow velocity from the sing-around frequencies has be modified. This new algorithm compensates for fast changes of fluid temperature during the sing-around measurement cycle. A complete derivatin is given for both laminar and turbulent flow. Test measurements comparing the new algorithm and the conventional one showed a superior performance of the new algorithm, especially in the case of rapidly changing fluid temperature.

    Building Automation Systems from Internet of Things2015Conference paper (Other academic)
    Abstract [en]

    Nowadays products and services are produced and delivered by numerous stakeholders, all required to interact with suppliers and customers in an efficient and flexible way. Energy consumption and energy usage environmental impact have become of paramount concern in those activities. Automation technology offers solutions to deal with those challenges. Automation technology as we know it today, however, has got some limitations. The emerging era of the Internet of Things (IoT) with its ease to build complex system of systems (SoS) opens new perspectives in the automation area.In this context, the European project Arrowhead envisions “Collaborative automation by networked embedded devices”. This necessitates a wide interoperability of devices, as well as systems and platforms. The proposed framework provides such interoperability at the service level. The Arrowhead framework efficiently support the development, deployment and operation of interconnected, collaborative systems. Arrowhead cloud automation systems are based on automation devices such as sensors, actuators, controllers, and others transformed into IoT-type of devices and systems adopting the Service Oriented Architecture philosophy. The building elements of a cloud automation system are systems that provide and consume services, and cooperate as systems of systems from which automation services like monitoring, control, optmisation, analysitcs etc are created. The building of complete automation systems is supported by orchestration and authorisation services.The presentation is going to discuss the new automation challenges, and solutions the Arrowhead framework offers.

    Communicating sensors for better diagnosises2007In: Medicinteknikdagarna 2007, Svensk förening för medicinsk teknik , 2007, p. 62-Conference paper (Other academic)
    Abstract [en]

    Current health care have developed a large number of sensors and measurements methodologies. Each of them in most cases dedicated for a single measurement to be made by an medical doctor or a nurse. It seams apparent that more and preciser information can be obtained if these measurements can be made under normal living conditions i.e. not at the hospital. This puts a focus to questions like mobility, ease of application, calibration and data communication. Thus issues like sensor size, weight, means of communication, field calibration, power lifetime etc. becomes extremely important. There is a long development in mobile medical monitoring/aiding technology like pace makers. Here size and power life time is feasible for patients. Communication means to the pace makers is also improved but most often requires a visit to the hospital. For much medical monitoring like blood pressure, ECG, pulse, etc. it would be beneficial to enable continuous monitoring with local on board diagnosis. The current strong research in light weight sensor nodes and sensor networks will open new perspectives to this. As an example of this I will discuss an mobile ECG development made jointly by Fraunhofer institute in Erlangen and Luleå University of Technology, EISLAB. The total device weighs less than 50g including battery. It supports Internet communication using Bluetooth connecting to the Internet via a standard mobile phone as access point. The device has on-board limited computation memory resources enabling simple local data analysis. This will reduce communication needs to "awake" messages and "alarm" messages upon which continuous data can be transfered to a medical center. This local analysis strategy will enable power life times for a 50 g sensor of many months according to first evaluations.

    Abstract [en]

    Maintenance of industrial infrastructure, machinery and communication is becoming a more and more critical issue in our society. The technology development in sensors and sensor networks will enable the embedding of "intelligence" into infrastructure, machinery and communication. Here Internet will become the communication paradigm to build on and already available communication infrastructure like the mobile phone networks will become the access network infrastructure. I will discuss such technology development including its capability for autonomous integration into its environment and autonomous operation. Thus enabling device and system diagnosis made available.

    Device for temperature compensation in an acoustic flow meterPatent (Other (popular science, discussion, etc.))
    Abstract [en]

    A meter includes a casing (1) with a fluid passage (2), in which two transducer mountings (3, 4) arranged at a distance (Lb) from each other support two transducers (5, 6) which are acoustically opposed to each other. Between the transducers (5, 6) there is a distance (Lu) over which they transmit and receive sound pulses through a fluid which in a direction (a) flows through the fluid passage (2). On the basis of the transit times of the sound pulses over the distance (Lu) both countercurrently with and countercurrently to the direction of flow (a), e.g. the velocity of the flow of the fluid is then calculated. A compensating device (8, 9) is arranged between at least one of the transducers (5, 6) and one of the transducer mounts (3, 4). The compensating device (8, 9) is made of a material having a known function of thermal expansion and having such a length that a longitudinal change, caused by a change in temperature of the fluid, of the distance (Lb) between the transducer mounts (3, 4) and, thus, of the distance (Lu) between the transducers (5, 6) is essentially compensated for by an opposite longitudinal change of the compensating device (8, 9).
