    Skiftning av åkermark för ett effektivare jordbruk2019Report (Other academic)
    Abstract [en]

    The number of farms in Sweden is decreasing while the size is increasing as most farms grow bigger in areal in order to remain competitive on the market. However, this situation set pressure on farmers looking to expand. It is rare for farmers to find available land close to their farm and therefore start to cultivate land further away. The extra distance has a cost, both for the farmers’ profitability and for the environment. Previous study looked at four particular farms focusing on the cost related to the harvest (cereal or forage). By simulating an exchange of land to closer ones, the cost for transport of the harvest was at least halved in the four cases. The study looked mostly at the technical aspect and included only the four cases.

    Therefore, this project aims to have a broader perspective, both in term of geography and also by looking at the social factors related to land exchange. During the project, a tool has been developed to calculate on a national level the distance between each field and the farm cultivating it. The tool is also used to minimise the distance between field and farm by allowing fields to be exchanged between farmers. Moreover, the tool has been used to estimate the potential for diesel use and cost reduction related to land exchange. Using the tool as ground for discussion, semi-structured interviews have been performed with farmers to understand the hinders and driving forces for land exchange between each other. During these interviews, the potential for implementing the tool was also discussed.

    The theoretical potential if limiting the exchange of land only between two parties at a time would be 12.4 %. Moreover, this number would decrease when considering the practical and social barriers such as the soil characteristics, the different cultivation methods (organic/conventional, no-till) and trust between farmers.

    The development of an application for optimal land exchange will require not only a robust model for distance calculation and optimization of land exchange but also a well-developed and user-friendly interface. Depending on how the application will be used, by single farmers or by consultants and advisers, different versions of an application may be required.

    The tool developed during the project has been positively received both by farmers during the interviews and also by other stakeholders during the concluding seminar. It gives a solid basis and acts as decision support tool. More is needed to agree on the best way to implement it in Sweden, in particular looking at the ownership, business model, and the development of new functions.

    Planeringssystem för ett effektivare jordbruk2019Report (Other academic)
    Abstract [en]

    The work presented in this report is one of three different areas of improving the efficiency of agricultural logistics that have been investigated in the project ”Energieffektivisering av Jordbrukets logistik - fördjupning och utveckling”. The three areas are, 1) Shifting of arable land (2) Planning tool for simulating, planning and optimizing logistical work on the farm (3) KPIs for logistics work at farm level to spur efficiency. All three areas are considered important parts in the work of reducing energy consumption and climate impact from agricultural transports and in food production.

    More efficient agricultural logistics can be achieved through better planning and coordination of all activities throughout the production process. This improved planning then requires decision support to get a holistic grip on the interacting parts of the process. In this report, we have begun the work to investigate how farmers can make agriculture more efficient by having access to good and simple planning and simulation systems, thereby reducing energy consumption and costs at farm level.

    We have made a review of which systems (for plant cultivation) that are available on the market today (with focus on the Swedish market) and identified shortcomings, gaps and needs for continued development. We have also in a case study exemplified the decisions a farmer make, and which tools are used. In the longer term, the aim is to have tools for simulation, planning and optimization of logistics for agriculture.

    There are many applications for planning, control and monitoring of agriculture activities on the market, but no purely logistics planning tools. Many of the tools available on the market are de facto not decision support, but rather business support, where the user can fill in the business conditions and to some extent follow the development during the year. For the applications to provide real decision support, they need to be more intelligent by being able to analyze large amounts of data smarter, make simulations of different scenarios and make assessments on plans. Internationally, the range of programs, apps and other IT support for agriculture management is very large, but the gaps are mainly the same. However, it is not easy to apply an internationally developed tool to Swedish conditions and regulations.

    Maskinnyckeltal för ett effektivare jordbruk2019Report (Other academic)
    Abstract [en]

    The work presented in this report is one of three different areas of improving the efficiency of agricultural logistics that have been investigated in the project ”Energieffektivisering av Jordbrukets logistik - fördjupning och utveckling”. The three areas are, 1) Shifting of arable land (2) Planning tool for simulating, planning and optimizing logistical work on the farm (3) KPIs for logistics work at farm level to spur efficiency. All three areas are considered to be important parts in the work of reducing energy consumption and climate impact from agricultural transports and in food production.

    In this report KPIs has been investigated by logging of machine activities on three farms. These farms were medium-sized with different production. Logging of diesel consumption and time required was carried out for a total of nine tractors on three farms. The logging equipment was connected to the tractors' CAN bus and data was downloaded to Drivec's cloud service via mobile broadband. Logging was also done by GPS data where the tractors were at a certain point in time and these were referred to different fields, farm centre areas, transport routes and for example areas where entrepreneurial work such as snow removal is performed.

    From these data, KPIs were calculated manually for diesel consumption and time consumption per crop, field and activity. The KPIs corresponded to what the farmers wanted but in order to be useful, logging needs to be more reliable and include all machines and activities in the plant production. One conclusion was that in order to utilize KPIs as a driver for change, the logging and KPI calculations must be done automatically and in addition, the KPIs calculated needs to have metadata that describes, for example, how representative the KPI is.

    The project also investigated the possibilities for sending this information automatically from Drivec's system to LRF Konsult's Digital Bonde and to integrate it with economic data.

    Further research activities are needed in order to implement the results from this project. Targeted work is needed with both further development and dissemination to farmers.

    Characterization of carbon nanotube doped carbon fiber prepreg laminate2012Conference paper (Refereed)
    Abstract [en]

    The current paper reports results from a preliminary study on PREGCYL™ NC R2HM-01 which is a carbon nanotube doped prepreg produced by Nanocyl. The work consisted of sample manufacturing in autoclave, microcopy analysis with XHR-SEM and mechanical testing. The mechanical testing consisted of tensile tests of unidirectional (in longitudinal direction) and cross-ply laminates. Test of unidirectional laminates showed that stiffness of the PREGCYL material is slightly higher than that of MTM55 composites (111GPa vs 102GPa). The results from tests of cross-ply laminates indicated that damage (transverse cracks) initiation is delayed in PREGCYL composites compare to the MTM55 material. Damage accumulation also seems to be slower in nano-doped composites.

    Batteridriven autonom jordbruksmaskin: Simulering av maskinaktiviteter på en svensk gård2017Report (Other academic)
    Abstract [en]

    In the project "Concept study battery-powered autonomous agricultural machine", an electric autonomous agricultural machine has been compared with a conventional diesel tractor by simulating all machine activities in a field on an organic dairy farm of 200 hectares during one year. Combine Harvesting was not included. The results show that it is possible to replace a conventional tractor (160 kW) with two autonomous battery-powered machines (36 kW motor, 113 kWh battery) with 15% lower costs. Even better, energy consumption was reduced by 58% and greenhouse gas emissions by 92% compared to diesel when energy consumption and greenhouse gas emissions from battery manufacturing were included. Furthermore local emissions were avoided and the sound pollution greatly reduced.  The major efficiency increase can be explained by the higher efficiency of electric power drivelines, and that the Swedish and Nordic electricity mix has very low greenhouse gas emissions and environmental impact. We also see that the weight of the conventional diesel tractor is more than four times the weight of the autonomous battery-powered, and that's only the tractor without any implements or payload. In the sensitivity calculations, changes in the cost of implements or driver / operator costs have the greatest impact on the total price. It is also important not to have a charger with low power, while the battery price does not have such big impact on the total cost. Continued research is needed to verify the theoretical simulation by building a test platform where knowledge can be gathered about the problems and opportunities in practical work - both in the field of battery-electric operation and autonomous driving.

    Förarlösa virkestruckar – en förstudie2017Report (Other academic)
    Abstract [en]

    This pilot study was initiated by the sawmill industry and aims to investigate the

    possibility of introducing autonomous vehicles in the form of forklift trucks for

    handling of timber packages at sawmills.

    The report presents the various levels of definition of autonomous vehicles, and in

    which activities we now can find examples of vehicles with varying degrees of autonomy.

    Various technical solutions to enable navigation and security for autonomous

    vehicles are presented as well as the security requirements of autonomous vehicles in

    different situations.

    To exemplify today’s and tomorrow’s use of forklifts, a sawmill’s package management

    is described, and a scenario for autonomous trucks is presented. Under that scenario,

    today’s six trucks are replaced with three or four driverless trucks. A brief economic

    calculation is made, describing the economic potential of driverless trucks. It shows

    that autonomous forklifts may be permitted to cost significantly more than conventional

    forklifts after the external security systems are installed, and still be profitable.

    The reason is mainly the personnel costs associated with running conventional forklifts.

    In conclusion, autonomous vehicles can be realized in the relatively near future in

    many industries. The sawmill industry is also expected to take advantage of the ongoing

    research and development. It is not least the economic parameters that weigh heavily

    pro an introduction of autonomous forklift trucks, while safety precautions can be a

    challenge.

    An intermediate step towards fully driverless forklift trucks can be a semi-autonomous

    solution, where the driver / operator manage a plurality of trucks by telemetry with

    manual assistance only when

    Controlling the architecture of nanofiber-coated microfibers using electrospinning2010In: Journal of Applied Polymer Science, ISSN 0021-8995, E-ISSN 1097-4628, Vol. 118, no 1, p. 511-517Article in journal (Refereed)
    Abstract [en]

    This study shows that electrospinning nanofibers onto single microfibers allows for careful tailoring of material properties that may suit a wide variety of applications. The nanofiber-coated microfibers are created by electrospinning nanofibers alongside a microfiber toward a collector that rotates around the microfiber. This force the nanofibers to be collected around the microfiber, creating a hierarchical structure that can be modified at nano scale. In this study, control of nanofiber diameters, nanofiber alignment, and nanofiber loading was evaluated. It was seen that varying polymer concentration affected the nanofiber diameters, collecting the nanofiber-coated microfibers at different speeds changed the degree of alignment of the nanofibers and that changing the polymer feeding rate affected the loading density of the nanofibers collected. The carefully designed nanofiber-coated microfibers have great potential in creation of highly porous materials with tailored properties down to nano scale. © 2010 Wiley Periodicals, Inc.
