Vid Volvo construction equipment AB, Component division i Eskilstuna, har nedväxling i förpackningsstorlekar genomförts som en del i en omfattande omställning mot Volvo Production System och Lean. Genom att producera med mindre satsstorlekar och hemtagningskvantiteter, vill Component division sänka sin kapitalbindning och bli flexiblare mot variationer i produktionen. Dessvärre påverkar nedväxlingen förpackningskostnaden till följd av ytterligare hantering, transport och administration. För Component division är det viktigt att få en god uppfattning om hur alla förpackningskostnader utvecklas med tiden. De vill i framtiden följa ett lämpligt nyckeltal för att se hur effektiva de är inom förpackningslogistik samt hur beslut och förändringar påverkar kostnaden.

The aim of thesis was to, through a action research study and through individual interviews with five students, clarify their perspective on educational assistance in high school. The study shows that students prefer teaching in small groups outside of regular whole class because it gives the them access to the factors they consider crucial for a functioning support-time whit a skilled and dedicated teatcher, in a calm and safe environment. Moreover, the students claim the importance of technical equipment especially in the Swedish subject, but also in other subjects. Today the educational assistance varies from an outside-the-class teaching situation to a whole-class situation with teacher support as well as technicaal equipment. When the student were asked to describe the cinditions under which studies can be conducted with the whole class they tried to imitate the learning environment they have in a small group.

Energy efficiency is today more important than ever, mainly due to the high energy prices and the approaching climate changes. Heating of buildings is an essential area within energy efficiency. Many buildings are old and were built at a time when the energy prices were low and the term ?energy efficiency? was unheard of. By applying today?s broad range of energy saving actions on these old, and thereby often, heating ineffective buildings, this area has a large potential in reducing energy consumption and costs.Churches and chapels are generally old buildings with, in many cases, ineffective heating systems and therefore consume much more energy than needed.

Holmen Skog is currently using a GPS-program called TraktInfo, originally developed within the company. They are now planning to switch to a new GPSprogram or allowing the contractors to buy other programs available from the logging equipment manufacturers. To be able to offer this flexibility, Holmen Skog needs to obtain information about the features offered by the different manufacturers in their specific programs, and also when the manufacturers are planning to start selling programs adapted to the new standard called StanFord2010. According to the study, the manufacturers are hesitant to StanFord2010 and there has also been a lack of clear signals from the customers and clients about what kind of different new features to include in the programs. The feature most frequently used by forest machine operators today is the option to keep record of the harvester?s path by creating a ?log plot?. This feature was not used to its full potential however, since only one out of eight of the forwarders included in the study had computers that were compatible with the harvester?s computer.

In the spring of 2014 Sweco Systems AB were commissioned to design a ventilation system for a newly built preschool in Linköping. Terms from the client was that it cost efficiency would cope with the energy demands that are placed on the building. The unit chosen was a cross-flow heat exchanger, and this work is to compare it with two other heat exchangers to see if a more energy and cost efficient could have been chosen. The heat exchangers that was chosen for the comparison was a rotating- and a counterflow heat exchanger. Simulations have been made to the different heat exchangers by the manufacturers.

This thesis concerns to investigate renovations of existing buildings aiming at enabling energy efficiency, from a conservation and restoration perspective. This includes performing case studies of three projects in the Gothenburg area where renovations has been done and an analysis of directives raised by the EU and later implemented by the Swedish National Board of Housing, Building and Planning, Boverket. In addition to these, regulations enforced by the Swedish law, related to the topic, have been considered.The investigated projects in this case were the housing cooperative Välten in Brämaregården, the Solar Buildings in Järnbrott and Gårdsten as well as Katjas Gata 119 at Backa Röd. In order to measure and compare the results of these projects a comparison between the pre- and post-restoration energy consumption have been performed. To capture additional perspectives the grading system Operation Kungsörn has been applied.Regarding the comparison of energy consumption the renovation of Katjas Gata 119 was found preferable but showed in my view lacking attention to the cultural heritage of the area.

The aim of this thesis is to answer whether a group of databases dedicated to selling books or a group of databases dedicated to lending books is more efficient. The measurements used to determine the efficiency of the two kinds of databases are Cumulated Gain and precision in modified versions. The inquiry has been conducted thus that the same 18 queries have been put forth to six databases and these results have consequently been judged according to relevance on a 4-graded scale by five respondents. The rankinglevels have then been merged to one average value per respondent and ranking. These values have then been used to determine CG/iCG/nCG and P@n per query, rank 1-10, per database and per group (the groups being STORE (BUTIK) and LIBRARY (BIBLIOTEK).

To get the maximal output of your exercise in gym machines, there are different factorsto be considered. For example the strength of the muscle varies dependent on the positionof the muscles.

The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.

The business potential of software defined radio (SDR) technology is studied by evaluating whether or not its characteristics correspond to those particular to a disruptive technology. The maturity of the SDR technology concept is illuminated by analyzing the opinions and perspectives of a selection of representatives for different stakeholders in the wireless communications market. Characteristics as, for example, the degree of consensus about the utility of SDR technology and the awareness of features and limitations are studied by application of the theory of technological frames. This theory helps us understand how and when technology evolution takes place. Finally we describe the value network structures of some potentially viable application areas for SDR and suggest some possible business opportunities based on SDR technology.This thesis is carried out as a case study and the research data is obtained from secondary sources, such as literature and Internet publications as well as interviews with people well experienced in the field of wireless communications.

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

This thesis investigates the regulation of hybrid work environments by focusing on the implementation of rules by both management and employees. It examines the methods used to measure compliance and the consequences of non-compliance within organizations. The study also explores how flexibility in work arrangements and the balance between work and personal life affect employee well-being and productivity. Furthermore, it highlights the critical role of self-leadership in navigating the complexities of hybrid work, emphasizing how effective self-management can enhance organizational efficiency and employee satisfaction. We have adopted a qualitative research approach and interviewed employees, managers, and HR personnel with experience in hybrid work. The different perspectives are expected to provide insights into this area by including all levels within an organization It is evident that organizations that have clearly established rules and guidelines regarding hybrid work have achieved the best desired results.
