    Practical 3-D beam pattern based channel modeling for multi-polarized massive MIMO systems2018In: Sensors, ISSN 1424-8220, E-ISSN 1424-8220, Vol. 18, no 4, article id 1186Article in journal (Refereed)
    Abstract [en]

    In this paper, a practical non-stationary three-dimensional (3-D) channel models for massive multiple-input multiple-output (MIMO) systems, considering beam patterns for different antenna elements, is proposed. The beam patterns using dipole antenna elements with different phase excitation toward the different direction of travels (DoTs) contributes various correlation weights for rays related towards/from the cluster, thus providing different elevation angle of arrivals (EAoAs) and elevation angle of departures (EAoDs) for each antenna element. These include the movements of the user that makes our channel to be a non-stationary model of clusters at the receiver (RX) on both the time and array axes. In addition, their impacts on 3-D massive MIMO channels are investigated via statistical properties including received spatial correlation. Additionally, the impact of elevation/azimuth angles of arrival on received spatial correlation is discussed. Furthermore, experimental validation of the proposed 3-D channel models on azimuth and elevation angles of the polarized antenna are specifically evaluated and compared through simulations. The proposed 3-D generic models are verified using relevant measurement data.

    Sensory, Tribological, and Rheological Profiling of “Clean Label” Starch–Lipid Complexes as Fat Replacers2019In: Starke (Weinheim), ISSN 0038-9056, E-ISSN 1521-379X, article id 1800340Article in journal (Refereed)
    Abstract [en]

    Dietary fat is highlighted as one of the critical risk factors that contribute to a number of chronic diseases. In this study, the sensory profile, tribological, and rheological properties of starch–lipid complexes, as a potential fat replacer, is investigated. Starch–lipid complexes are formulated by incorporating food friendly chemicals (stearic acid and monoglyceride) into maize starch by wet-heat processing and compared with a commercial fat replacer. The starch–lipid complexes have good lubricating properties and are described by the panelists as being glossy, smooth, creamy, and easy-to-swallow. All the complexes exhibited a shear thinning behavior and had lower firmness, due to their non-gelling ability compared to the commercial fat replacer. The properties of starch–lipid complexes for non-gelling, good lubricating, smooth, and creamy can be related to the formation of amylose–lipid complexes and other properties. The complexes have the potential to produce non-gelling emulsions having a creamy and smooth texture with no adverse effect on the overall aroma and flavor.

    The EMRP project GraphOhm- Towards quantum resistance metrology based on graphene2014In: CPEM 2014, 2014, , p. 548 - 549p. 548-549Conference paper (Refereed)
    Abstract [en]

    A new joint research project (JRP) integrating metrology institutes and universities from nine countries is aimed at realization of a new generation of standards for quantum resistance metrology. The project exploits graphene's properties to simplify operation of standards without compromising the unprecedented precision delivered by semiconductor quantum Hall devices. Higher operating temperatures (above 4.2 K, and up to 8 K) and together with lower magnetic fields (below 5 T, and potentially down to 2 T) will lead to a significantly improved and cost-saving dissemination of intrinsically referenced resistance standards to all end-users relying on electrical measurements.

    A performance model for integrated layer processing1997Conference paper (Refereed)
    Abstract [en]

    Integrated Layer Processing is an implementation technique for data manipulation functions in communication protocols. The purpose of this technique is to increase communication performance. It reduces the number of memory accesses and thus relieves the memory bandwidth bottleneck. Integrated Layer Processing can however, in some situations, substantially increase the number of memory accesses, and therefore instead reduce performance. The main reason is contention for processor registers. We present a performance model that captures the memory behavior of data manipulation functions for both integrated and sequential implementations. By comparing the model to measurements of real and synthetic data manipulation functions, we show that the model accurately predicts the performance. The model can be used to assess whether an integrated implementation will perform better or worse than a sequential implementation. The situations where integration would reduce performance can then be avoided without spending a lot of effort on a more complex integrated implementation.

    NetInf Routing Using Hints2013Conference paper (Refereed)
    Abstract [en]

    We define a global routing mechanism for the NetInf protocol, part of the NetInf information-centric networking architecture. The mechanism makes use of two levels of aggregation in order to provide the scalability needed for a global network. An anticipated $10^{15}$ number of individual named data objects are aggregated to in the order of 500K routing hints which are very feasible to handle with existing routing technology. The hints are then used to forward requests for named data towards the publisher.

    Dimensioning links for IP telephony2001In: Proceedings of the 2nd IP-Telephony Workshop (IPtel 2001), 2-3 April 2001, New York City, New York, USA, 2001, 1Conference paper (Refereed)
    Abstract [en]

    Packet loss is an important parameter for dimensioning network links or traffic classes carrying IP telephony traffic. We present a model based on the Markov modulated Poisson process (MMPP) which calculates packet loss probabilities for a set of super positioned voice input sources and the specified link properties. We do not introduce another new model to the community, rather try and verify one of the existing models via extensive simulation and a real world implementation. A plethora of excellent research on queuing theory is still in the domain of ATM researchers and we attempt to highlight its validity to the IP Telephony community. Packet level simulations show very good correspondence with the predictions of the model. Our main contribution is the verification of the MMPP model with measurements in a laboratory environment. The loss rates predicted by the model are in general close to the measured loss rates and the loss rates obtained with simulation. The general conclusion is that the MMPP-based model is a tool well suited for dimensioning links carrying packetized voice in a system with limited buffer space.

    Dimensioning Links for IP Telephony2000Report (Other academic)
    Abstract [en]

    Transmitting telephone calls over the Internet causes problems not present in current telephone technology such as packet loss and delay due to queueing in routers. In this undergraduate thesis we study how a Markov modulated Poisson process is applied as an arrival process to a multiplexer and we study the performance in terms of loss probability. The input consists of the superposition of independent voice sources. The predictions of the model is compared with results obtained with simulations of the multiplexer made with a network simulator. The buffer occupancy distribution is also studied and we see how this distribution changes as the load increases.

    Content, Connectivity and Cloud: Ingredients for the Network of the Future2011In: IEEE Communications Magazine, ISSN 0163-6804, E-ISSN 1558-1896, Vol. 49, p. 62-70Article in journal (Refereed)
    Abstract [en]

    A new network architecture for the Internet needs ingredients from three approaches: information-centric networking, cloud computing integrated with networking, and open connectivity. Information-centric networking considers pieces of information as first-class entities of a networking architecture, rather than only indirectly identifying and manipulating them via a node hosting that information; this way, information becomes independent from the devices they are stored in, enabling efficient and application-independent information caching in the network. Cloud networking offers a combination and integration of cloud computing and virtual networking. It is a solution that distributes the benefits of cloud computing more deeply into the network, and provides a tighter integration of virtualisation features at computing and networking levels. To support these concepts, open connectivity services need to provide advanced transport and networking mechanisms, making use of network and path diversity (even leveraging direct optical paths) and encoding techniques, and dealing with ubiquitous mobility of user, content and information objects in a unified way.

    Integrated layer processing can be hazardous to your performance1997Conference paper (Refereed)
    Abstract [en]

    Integrated Layer Processing (ILP) has been presented as an implementation technique to improve communication protocol performance by reducing the number of memory references. Previous research has however not pointed out that in some circumstances ILP can significantly increase the number of memory references, resulting in lower communication throughput. We explore the performance effects of applying ILP to data manipulation functions with varying characteristics. The functions are generated from a set of parameters including input and output block size, state size and number of instructions. We present experimental data for varying function state sizes, number of integrated functions and instruction counts. The results clearly show that the aggregated state of the functions must fit in registers for ILP to be competitive.

    The applicability of integrated layer processing1998In: IEEE Journal on Selected Areas in Communications, Vol. 16, no 3, p. 317-331Article in journal (Refereed)
    Abstract [en]

    In this paper we review previous work on the applicability and performance of Integrated Layer Processing (ILP). ILP has been shown to clearly improve computer communication performance when integrating simple data manipulation functions, but the situation has been less clear for more complex functions and complete systems. We discuss complications when applying ILP to protocol stacks, the requirements of ILP on the communication subsystem, caching aspects, the importance of the processor registers, and a model for predicting the performance of data manipulation functions. We conclude that the main drawback of ILP is its limited aplicability to complex data manipulation functions. The performance to expect from an ILP implementation also depends heavily on the protocol architecture and the host system architecture.

    Towards predictable ILP performance-controlling communication buffer cache effects1996In: The Australian Computer Journal, Vol. 28, p. 66-71Article in journal (Refereed)
    Abstract [en]

    Cache memory behavior is becoming more and more important as the speed of CPUs is increasing faster than the speed of memories. The operation of caches are statistical which means that the system level performance becomes unpredictable. In this paper we investigate the worst case behavior of cache line conflicts in the context of communication protocols implemented using Integrated Layer Processing. The goal of our work is to control the cache by placing communication buffers and code in non-conflicting positions in the cache. The result would be higher and more predictable performance. Our first results indicate that the worst case behavior can be up to almost four times slower than the best case.

    The performance of a no-copy API for communication1995Conference paper (Refereed)
    Abstract [en]

    We present a so-called no-copy Application Programming Interface (API) for communication. The interface avoids copying when data is transferred between the application and operating system kernel address spaces. The API is an extension to the socket interface for SunOS, and has been implemented on Sun SPARCstations equipped with Fore Systems ATM adapters. Throughput for the no-copy API is 85 Mbit/s for 8K UDP messages, to be compared to 57 Mbit/s for the regular API on the SPARCstation 2. Processing times through the TCP and UDP stacks are reduced by up to 30% for the SPARCstation 2 and by more than 50% for the SPARCstation 10.

    Invariants: A New Design Methodology for Network Architectures2004Conference paper (Refereed)
    Abstract [en]

    The first age of Internet architectural thinking concentrated on defining the correct principles for designing a packet-switched network and its application protocol suites. Although these same principles remain valid today, they do not address the question of how to reason about the evolution of the Internet or its interworking with other networks of very different heritages. This paper proposes a complementary methodology, motivated by the view that evolution and interworking flexibility are determined not so much by the principles applied during initial design, but by the choice of fundamental components or "design invariants" in terms of which the design is expressed. The paper discusses the characteristics of such invariants, including examples from the Internet and other networks, and considers what attributes of invariants best support architectural flexibility.

    Design considerations for a network of information2008Conference paper (Refereed)
    Abstract [en]

    The existing Internet ecosystem is a result of decades of evolution. It has managed to scale well beyond the original aspirations. Evolution, though, highlighted a certain degree of inadequacies that is well documented. In this position paper we present the design considerations for a re-architected global networking architecture which delivers dissemination and non-dissemination objects only to consenting recipients, reducing unwanted traffic, linking information producers with consumers independently of the hosts involved, and connects the digital with the physical world. We consider issues ranging from the proposed object identifier/locator split to security and trust as we transition towards a Network of Information and relate our work with the emerging paradigm of publish/subscribe architectures. We introduce the fundamental components of a Network of Information, i.e., name resolution, routing, storage, and search, and close this paper with a discussion about future work.

    Abstract [en]

    The information-centric networking (ICN) concept is a significant common approach of several Future Internet research activities. The approach leverages in-network caching, multi-party communication through replication, and interaction models decoupling senders and receivers. The goal is to provide a network infrastructure service that is better suited to today's use, in particular content distribution and mobility, and that is more resilient to disruptions and failures. The ICN approach is being explored by a number of research projects. We compare and discuss design choices and features of proposed ICN architectures, focussing on the following main components: named data objects, naming and security, API, routing and transport, and caching. We also discuss the advantages of the ICN approach in general.

    Names, addresses and identities in ambient networks2005Conference paper (Refereed)
    Abstract [en]

    Ambient Networks interconnect independent realms that may use different local network technologies and may belong to different administrative or legal entities. At the core of these advanced internetworking concepts is a flexible naming architecture based on dynamic indirections between names, addresses and identities. This paper gives an overview of the connectivity abstractions of Ambient Networks and then describes its naming architecture in detail, comparing and contrasting them to other related next-generation network architectures.

    Ambient networks: Bridging heterogeneous network domains2005Conference paper (Refereed)
    Abstract [en]

    Providing end-to-end communication in heterogeneous internetworking environments is a challenge. Two fundamental problems are bridging between different internetworking technologies and hiding of network complexity and differences from both applications and application developers. This paper presents abstraction and naming mechanisms that address these challenges in the Ambient Networks project. Connectivity abstractions hide the differences of heterogeneous internetworking technologies and enable applications to operate across them. A common naming framework enables end-to-end communication across otherwise independent internetworks and supports advanced networking capabilities, such as indirection or delegation, through dynamic bindings between named entities.

    Increasing communication performance with a minimal-copy data path supporting ILP and ALF1996In: Journal of High Speed Networks, Vol. 5, no 2, p. 203-214Article in journal (Refereed)
    Abstract [en]

    Many current implementations of communication subsystems on workstation class computers transfer communication data to and from primary memory several times. This is due to software copying between user and operating system address spaces, presentation layer data conversion and other data manipulation functions. The consequence is that memory bandwidth is one of the major performance bottlenecks limiting high speed communication on these systems. We propose a communication subsystem architecture with a minimal-copy data path to widen this bottleneck. The architecture is tailored for protocol implementations using Integrated Layer Processing (ILP) and Application Layer Framing (ALF). We choose to implement these protocols in the address space of the application program. We present a new application program interface (API) between the protocols and the communication service in the operating system kernel. The API does not copy data, but instead passes pointers to page size data buffers. We analyze and discuss ILP loop and cache memory requirements on these buffers. Initial experiments show that the API can increase the communication performance with 50% compared to a standard BSD Unix socket interface.

    Are MIRCC and Rate-based Congestion Control in ICN READY for Variable Link Capacity?2017Conference paper (Refereed)
    Abstract [en]

    Information-centric networking~(ICN) has been introduced as a potential future networking architecture. ICN promises an architecture that makes information independent from location, application, storage, and transportation. Still, it is not without challenges. Notably, there are several outstanding issues regarding congestion control: Since ICN is more or less oblivious to the location of information, it opens up for a single application flow to have several sources, something which blurs the notion of transport flows, and makes it very difficult to employ traditional end-to-end congestion control schemes in these networks. Instead, ICN networks often make use of hop-by-hop congestion control schemes. However, these schemes are also tainted with problems, e.g., several of the proposed ICN congestion controls assume fixed link capacities that are known beforehand. Since this seldom is the case, this paper evaluates the consequences in terms of latency, throughput, and link usage, variable link capacities have on a hop-by-hop congestion control scheme, such as the one employed by the Multipath-aware ICN Rate-based Congestion Control~(MIRCC). The evaluation was carried out in the OMNeT++ simulator, and demonstrates how seemingly small variations in link capacity significantly deteriorate both latency and throughput, and often result in inefficient network link usage.

    ICN congestion control for wireless links2018Conference paper (Refereed)
    Abstract [en]

    Information-centric networking (ICN) with its design around named-based forwarding and in-network caching holds great promises to become a key architecture for the future Internet. Many proposed ICN hop-by-hop congestion control schemes assume a fixed and known link capacity, which rarely - if ever - holds true for wireless links. Firstly, we demonstrate that although these congestion control schemes are able to fairly well utilise the available wireless link capacity, they greatly fail to keep the delay low. In fact, they essentially offer the same delay as in the case with no hop-by-hop, only end-to-end, congestion control. Secondly, we show that by complementing these schemes with an easy-to-implement, packet-train capacity estimator, we reduce the delay to a level significantly lower than what is obtained with only end-to-end congestion control, while still being able to keep the link utilisation at a high level.

    Demo: Experimental Feasibility Study of CCN-lite on Contiki Motes for IoT Data Streams2016In: Proceedings of the 3rd ACM Conference on Information-Centric Networking, 2016, p. 221-222Conference paper (Refereed)
    Abstract [en]

    Many IoT applications are inherently information-centric, making it advantageous to use ICN transport. We demonstrate CCN-lite ported to run on Contiki sensor motes with limited processing and storage resources. We show a method for mapping streams of sensor data to a stream of immutable CCN named data objects, and an adaptive probing method to find the newest value. We also demonstrate interoperation between MQTT and CCN via a gateway. A higher level goal is to use ICN as an open interface for accessing IoT data.

    SPION: Secure Protocols in OSI Networks1989Report (Other academic)
    Abstract [en]

    SPION: Secure Protocols in OSI Networks This report describes how security services can be realized in a computer network using the protocols of the Open Systems Interconnection (OSI) reference model for communication. The report starts with defining security requirements for a "typical" local area network in a company, university or similar organization. It is assumed that the organization does not use the network for transfer of extremely sensitive information, such as military secrets. A set of security services, as specified in the OSI security architecture, are selected in order to satisfy the requirements. The selected services are then placed in suitable layers of the OSI model according to the criteria in the security architecture, and to the taste of the authors. The report concentrates on the transport layer. An extension of the OSI transport protocol, class 4, including security services is described in detail. The protocol is a fully compatible extension of the standard transport protocol. Key management is another topic which is included in the report. A key management system for handling public keys and digital signatures based on an article by Dorothy E. Denning is described. The system includes functions for distributing and validating public keys, and registering and later verifying digital signatures. A key management protocol supporting these functions is defined for communication between ordinary open systems and special key server systems.

    Experiments with Subversion Over OpenNetInf and CCNx2011Conference paper (Refereed)
    Abstract [en]

    We describe experiences and insights from adapting the Subversion version control system to use the network service of two information-centric networking (ICN) prototypes: OpenNetInf and CCNx. The evaluation is done using a local collaboration scenario, common in our own project work where a group of people meet and share documents through a Subversion repository. The measurements show a performance benefit already with two clients in some of the studied scenarios, despite being done on un-optimised research prototypes. The conclusion is that ICN clearly is beneficial also for non mass-distribution applications.

The conclusion is that ICN clearly is beneficial also for non mass-distribution applications. It was straightforward to adapt Subversion to fetch updated files from the repository using the ICN network service. The adaptation however neglected access control which will need a different approach in ICN than an authenticated SSL tunnel. Another insight from the experiments is that care needs to be taken when implementing the heavy ICN hash and signature calculations. In the prototypes, these are done serially, but we see an opportunity for parallelisation, making use of current multi-core processors.

    A Host Interface to the DTM Network1992Report (Other academic)
    Abstract [en]

    DTM, dynamic synchronous transfer mode, is a new time division multiplexing technique for fiber networks currently being developed and implemented at the Royal Institute of Technology in Stockholm, Sweden. This paper describes the hardware and software aspects of the design of an SBus host interface to the DTM network for a Sun SPARCstation. The interface is based on a dual port memory residing on the interface card and accesible over the SBus from the host CPU. The host operating system allocates message buffers directly in this memory. The interface has hardware support for segmenting and reassembling packets to and from the data units of the DTM. The software part of the interface manages the shared memory and the virtual circuits provided by the DTM network.

    Review of methodological choices in LCA of biorefinery systems - key issues and recommendations2015In: Biofuels, Bioproducts and Biorefining, ISSN 1932-104X, E-ISSN 1932-1031, Vol. 9, no 5, p. 606-619Article in journal (Refereed)
    Abstract [en]

    The current trend in biomass conversion technologies is toward more efficient utilization of biomass feedstock in multiproduct biorefineries. Many life-cycle assessment (LCA) studies of biorefinery systems have been performed but differ in how they use the LCA methodology. Based on a review of existing LCA standards and guidelines, this paper provides recommendations on how to handle key methodological issues when performing LCA studies of biorefinery systems. Six key issues were identified: (i) goal definition, (ii) functional unit, (iii) allocation of biorefinery outputs, (iv) allocation of biomass feedstock, (v) land use, and (vi) biogenic carbon and timing of emissions. Many of the standards and guidelines reviewed here provide only general methodological recommendations. Some make more specific methodological recommendations, but these often differ between standards. In this paper we present some clarifications (e.g. examples of research questions and suitable functional units) and methodological recommendations (e.g. on allocation).

    Återvinning av växtnäringsämnen ur avloppsvatten – hur gör vi hållbarhetsbedömningar på bästa sätt?2020Report (Other academic)
    Abstract [sv]

    För att kunna producera tillräckligt med mat på ett hållbart sätt behöver vi hushålla med växtnäring, och se till att den näring som redan finns i omlopp används på ett klokt sätt. Nya direktiv kring slamanvändning, krav på återförsel av växtnäring och hårdare utsläppskrav på reningsverk innebär att nya system och tekniker behöver utvecklas. Det kan dock vara svårt att veta vilket system eller vilken teknik som ger den största nyttan. Systemanalytiska metoder kan hjälpa till att tydliggöra dessa komplexa frågor.

    Målet med denna studie är att på ett övergripande sätt ge en insikt i hur arbetet kring hållbarhetsbedömningar kopplat till kommunal avloppsvattenrening och återföring av näringsämnen, med fokus på fosfor och kväve kan genomföras. Vidare har fokus legat på metodfrågor inom livscykelanalys (LCA), men en utblick kring andra hållbarhetsbedömningsmetoder ges även i en mindre omfattning. Mycket av det som behandlas inom LCA har dock bäring även för andra metoder för hållbarhetsbedömning.

    Idag finns det olika typer av standarder och riktlinjer för hur LCA-studier bör utföras, dock saknas det specifika riktlinjer för LCA-studier kopplade till näringsåtervinning ur avlopp. Det finns flera skäl till att LCA-metodfrågor kopplade till näringsåterföring behöver utredas; LCA är en metod som framförallt inriktar sig på att bedöma miljöpåverkan av en produkt, medan avloppsvattenrening ofta sker i kommunal regi och i nuläget är inriktat på att rena avloppsvatten och inte fokuserar på att producera produkter. Avloppssystem är ofta integrerade med både vattenförsörjning, energisystemet och jordbruket på ett intrikat sätt. Avlopp är också en sektor som har utsläpp både till luft och vatten, och metoder för att korrekt kunna bedöma dessa utsläpps påverkan på miljö är viktiga att utreda. Användningsområdet för LCA är väldigt brett. LCA kan dock inte svara på om det system som utvärderas är hållbart, bara om systemet har mer eller mindre påverkan än ett annat. LCA kan alltså inte svara på frågeställningar som: Vad är en hållbar återvinningsgrad för växtnäringsämnen?

    Arbetet har resulterat i en diskussion kring när LCA eller systemanalys lämpar sig och vad man bör tänka på när man genomför en LCA och vilka delar som bör ingå. Inom ramen för detta arbete anordnades även en workshop där berörda intressenter deltog från forskning, myndigheter och branschen. Syftet med workshopen var att få in synpunkter kring hur en systemanalys eller LCA bör läggas upp för att ge användbara resultat i beslutsfattande.

    I första hand vänder sig rapporten till dem som arbetar med kommunal avloppsvattenrening, teknikutveckling och myndigheter inom detta område, som har en grundförståelse för systemanalys och vill veta mer.

    Fosforprodukter av slam – energianvändning och klimatpåverkan2019Report (Other academic)
    Abstract [en]

    The purpose of this study was to compare the energy use and climate impact of extracting phosphorus (P) from sewage sludge, compared with mineral phosphorus from mining. The two processes that are studied are struvite precipitation and extraction of phosphorus from sludge ash (AshDec). We also looked at the potential recycling rate of plant nutrients in the different systems.

    In the study, we have calculated the environmental impact of introducing the processes for P-recovery, related to a conventional sewage treatment plant with chemical precipitation. It is therefore only the differences that arise in comparison with the reference plant that are included in the calculations. You can think like this: there is an existing sewage treatment plant, where you introduce P recycling. All changes in environmental impact that arise in connection with the investment in this new process are burdens the new P-product.

    The results show that the AshDec scenario has the best recovery rate of phosphorus and energy balance, while the struvite scenario shows the best return rate of nitrogen and the lowest climate impact. However, the sensitivity analyzes show that the results are strongly influenced by different assumptions. For the AshDec scenario, assumption about nitrous oxide emissions from incineration of sludge as well as the handling of energy surplus is crucial. For the struvite scenario, assumptions around the reconstruction of the sewage treatment plant to biological phosphor cleaning is of great significance, especially if the biogas production is affected.

    Value chains for integrated production of liquefied bio-SNG at sawmill sites – Techno-economic and carbon footprint evaluation2017In: Applied Energy, ISSN 0306-2619, E-ISSN 1872-9118, Vol. 206, p. 1590-1608Article in journal (Refereed)
    Abstract [en]

    Industry's increasing demand for liquefied natural gas could be met in the future by liquefied methane produced from biomass feedstock (LBG - liquefied biogas). This study presents results from an investigation of value chains for integrated production of LBG at a generic sawmill site, based on gasification of sawmill waste streams and forest residues. The objective was to investigate the cost for, as well as the carbon footprint reduction associated with, production and use of LBG as a fuel. Five different LBG plant sizes were investigated in combination with three different sawmill sizes. The resulting cases differ regarding biomass feedstock composition, biomass transportation distances, LBG plant sizes, how efficiently the excess heat from the LBG plant is used, and LBG distribution distances. Pinch technology was used to quantify the heat integration opportunities and to design the process steam network. The results show that efficient use of energy within the integrated process has the largest impact on the performance of the value chain in terms of carbon footprint. The fuel production cost are mainly determined by the investment cost of the plant, as well as feedstock transportation costs, which mainly affects larger plants. Production costs are shown to range from 68 to 156 EUR/MW hfuel and the carbon footprint ranges from 175 to 250 kg GHG-eq/MW hnet biomass assuming that the product is used to substitute fossil LNG fuel. The results indicate that process integration of an indirect biomass gasifier for LBG production is an effective way for a sawmill to utilize its by-products. Integration of this type of biorefinery can be done in such a way that the plant can still cover its heating needs whilst expanding its product portfolio in a competitive way, both from a carbon footprint and cost perspective. The results also indicate that the gains associated with efficient heat integration are important to achieve an efficient value chain.

    Influence of chloride and moisture content on steel rebar corrosion in concrete2016In: Materials and corrosion - Werkstoffe und Korrosion, ISSN 0947-5117, E-ISSN 1521-4176, Vol. 67, no 10, p. 1049-1058Article in journal (Refereed)
    Abstract [en]

    Reinforced mortar samples were exposed in humidity chambers with different relative humidity or exposed in cyclic moisture conditions. The rebars were in an “as received” condition meaning that the preexisting oxide scale were intact. The lowest chloride concentration that initiated corrosion was 1% Cl− by mass of cement, corrosion was then observed for samples exposed at 97% relative humidity. It is suggested that the corrosion rate decreases when samples are exposed to a relative humidity lower than 97%. The results indicate that threshold levels should be evaluated at rather humid conditions (97%) despite the fact that the maximum corrosion rate at higher chloride levels is observed in the interval 91–94%. For samples exposed to cyclic moisture conditions, a lower chloride concentration was needed to initiate corrosion compared to samples exposed in static moisture conditions.

    Electrochemical properties of oxide scale on steel exposed in saturated calcium hydroxide solutions with or without chlorides2018In: International Journal of Corrosion, ISSN 1687-9325, E-ISSN 1687-9333, Vol. 2018, article id 5623504Article in journal (Refereed)
    Abstract [en]

    The electrochemical properties of various iron oxide scales on steel exposed in saturated calcium hydroxide solutions were investigated. The iron oxide scales were manufactured by different heat treatments and grinding processes and characterized using X-ray diffraction and scanning electron microscope. The electrochemical properties of the scales were assessed by measuring the corrosion potential and using electrochemical impedance spectroscopy and potentiodynamic polarization curves. It was found that wustite and magnetite are less noble compared to hematite but are more effective as cathodic surfaces. The results show that the electrochemical properties of the mill scale can be an important contributing factor in the corrosion of steel in concrete.

    Economic potential for substitution of fossil fuels with liquefied biomethane in Swedish iron and steel industry – Synergy and competition with other sectors2020In: Energy Conversion and Management, ISSN 0196-8904, E-ISSN 1879-2227, Vol. 209, article id 112641Article in journal (Refereed)
    Abstract [en]

    In Sweden, the iron and steel industry (ISI) is a major source of greenhouse gas (GHG) emissions. Most of the emissions result from the use of fossil reducing agents. Nevertheless, the use of fossil fuels for other purposes must also be eliminated in order to reach the Swedish emissions reduction targets. In this study, we investigate the possibility to replace fossil gaseous and liquid fuels used for heating in the ISI, with liquefied biomethane (LBG) produced through gasification of forest residues. We hypothesize that such utilization of fuels in the Swedish ISI is insufficient to independently drive the development of large-scale LBG production, and that other sectors demanding LBG, e.g., for transportation, can be expected to influence the economic potential for the ISI to switch to LBG. The paper investigates how demand for LBG from other sectors can contribute to, or prevent, a phase-out of fossil fuels used for heating purposes in the ISI under different future energy market scenarios, with additional analysis of the impact of a CO2 emissions charge. A geographically explicit cost-minimizing biofuel production localization model is combined with heat integration and energy market scenario analysis. The results show that from a set of possible future energy market scenarios, none yielded more than a 9% replacement of fossil fuels used for heating purposes in the ISI, and only when there was also a demand for LBG from other sectors. The scenarios corresponding to a more ambitious GHG mitigation policy did not achieve higher adoption of LBG, due to corresponding higher biomass prices. A CO2 charge exceeding 200 EUR/tonCO2 would be required to achieve a full phase-out of fossil fuels used for heating purposes in the ISI. We conclude that with the current policy situation, substitution of fossil fuels by LBG will not be economically feasible for the Swedish ISI.
