Purpose: The purpose of  this thesis is to see if the 100 largest Swedish companies are present on  Facebook, and if they are, how they use their business pages. Further the  customers’ perception of companies’ use of Facebook will be included. To  investigate this, three research questions were created. Background: As Web 2.0 and  its application has changed, the use of Internet, both for companies and  customers, there has been change in how information is delivered and how  people take in information. One application of Web 2.0 is Facebook, and in  this investigation the authors will look at the use of the application in  companies marketing strategy.  Many researchers  and marketers (Constantinides & Fountain, 2008; Carlsson, 2009; Yang et  al., 2009) recognizes the importance for companies to take advantage of this  new media and sees a value generating process for both company and customer,  but how this value generates profits is harder to identify. Further the  market and possibility to reach customers is every day increasing as Facebook  has gone from 100 million in 2008 to approximately 600 million members in 2011. Today in  Sweden, over four million people have a Facebook account.  Method: To gather empirical data the use of a coding sheet  has been developed through content analysis when investigating the selected  companies’ business pages. The companies were found from a list over the 100  largest Swedish companies ranked after turnover. Further to collect the customers’  perception of companies on Facebook a focus group were conducted. In the  focus group a semi-structured interview approach was chosen to create an open  discussion within the group but still maintaining on the subject in hand. To  analyze the empirical findings theories about social media, customer loyalty  and communication were used.  Conclusion: The authors of this thesis have determined three  different appearance areas by companies on Facebook; support forum,  advertising channel and just exist on the social media. Two main ways for  companies to use Facebook is as a customer support page or as an advertising/promotion/publicity  channel. In customers support pages the communication between the company and  customer is more substantial and different types of communication are to be  found such as B2C, C2B and C2C. By using  Facebook as advertising /promotion /publicity page the companies communicate  more through pictures and videos that is pushed out  by the company. The customers interact through viewing and commenting the  uploaded material. The result from the focus group  showed that the customer appreciated the advertising/promotion/publicity page  as this corresponds with their perception of companies on Facebook. The  participant saw the customer support page on Facebook as unserious and not a  suitable way of communicating with a company.

Uppgiften som detta examensarbete går ut på är att utveckla en ny steghållare som ska ingå i Thules produktserie Professional. Det är önskvärt att kunna lasta stegen bakifrån och möjliggöra lastning från marken även på högre skåpbilar. Steghållaren ska framförallt vara anpassad till yrkesmän, såsom hantverkare, målare, etc. Därför söker Thule en robust, säker och lättmanövrerad steghållare med attraktivt utseende. Steghållaren ska minska den tid det tar att lasta på och av stegen. Produkten måste även klara miljökraven samt korrosion då den kommer att användas största delen utomhus. Steghållaren ska passa både till Thules Professional bar och Thules fyrkantsrör. / The task given by Thule has the purpose of develop a new ladder holder for the product line Professional. Thule is obtaining a robust, safe, and easy to handle ladder holder with an attractive look. It is desirable to be able to load the ladder from behind and make loading standing on the ground possible even on top of higher vans. The ladder holder is supposed to be suited for professionals such as craftsmen and painters. This product is designed to reduce time waste and heavy lifts. It is also desirable to withstand corrosion and meet the environmental requirements.

This study describes the design and fabrication of dual-mode film bulk acoustic resonator (TFBAR) devices to construct wafer level T-ladder type filters. Reactive radio-frequency (RF) magnetron sputtering method was used to deposit c-axis- tilted ZnO piezoelectric thin films. The piezoelectric ZnO thin films were deposited by a two-step method at room temperature with off-axis. In this investigation, off-axis distance was varied to determine the optimal growth parameters of the tilted piezoelectric thin film. The SEM and XRD analysis reveal that ZnO thin films deposited at off-axis distances of 35 mm yielded a highly textured and sufficiently-tilted ZnO piezoelectric layer for dual-mode TFBAR. Additionally, the ZnO piezoelectric layer with off-axis distances of 35 mm exhibited enhanced competitive growth, and had a c-axis-tilted angle of 5¢X. To explore the relationship between the c-axis-tilted angle and the dual-mode resonance frequency responses (fL and fS) of TFBAR, two TFBAR devices were fabricated with ZnO c-axis tilted at 4.4¢X and 5¢X, respectively. The TFBAR device with 5¢X-tilted ZnO layer exists shear and longitudinal resonant modes. The center-frequency of longitudinal resonant mode is 2.2 times that of the shear resonant mode. The longitudinal mode is suitable for designing as a communication receiver (Rx) device at WCDMA band. On the other hand, the shear mode of TFBAR is suitable for EGSM-900 band. To optimize the characteristics, the filter was annealed by CTA treatment in 400 ¢J. For the frequency responses of the longitudinal wave, the insertion loss was upgraded from -5.77 dB without annealing to -4.85 dB as annealed, the band rejection was reduced from 13.57 dB to 12.65 dB, the bandwidth was broaden from 69.69 MHz to 73.12 MHz. On the other hand, for the frequency responses of the shear wave, the insertion loss was upgraded from -9.94 dB to -8.21 dB, the band rejection was reduced from 13.74 dB to 13 dB, the bandwidth was decreased from 28.13 MHz to 28.12 MHz.

Laser-atom interactions create atomic coherence and large nonlinear atomic polarization. We investigate resonant laser-atom interactions to generate large nonlinearities and control them using magneto-optical fields. Coherent control of high-order susceptibilities and magneto-optical rotation are demonstrated. Experiments are supported by theoretical studies that effectively describe the observed phenomena. It is shown that a new coherent field, with polarization orthogonal to a weak signal field, can be parametrically generated via an all-resonant four-wave-mixing process. This is demonstrated in a double-ladder system having two intermediate states between a ground and an excited state. It is shown that the parametricgeneration process can be coherently controlled by coupling lasers and magnetic fields. It is theoretically established that the underlying physics is a resonant three-photon process with a wide domain of control parameters. Electromagnetically induced transparency (EIT), where absorption of a weak probe is suppressed via quantum interference, is demonstrated in a usual three-level ladder system. It is observed that in contrast with EIT in a usual ladder system, addition of a second channel helps to suppress the absorption of two weak probe fields in the double-ladder system. The resulting enhancement of transmission in two different channels is due to gain caused by three-photon processes. Coherent control is strongly limited by coherence lifetime, which is the inverse of the dephasing rate. A lambda-system, having two ground states coupled to a common excited state by lasers, can generate a new eigen (dark)-state that is transparent to incoming fields and hence suppresses fluorescence. However, ground-state dephasing perturbs the dark state. A new method for measuring the ground-state dephasing rate from fluorescence signals is proposed and a proof-of-principle experiment demonstrated. While two laser fields in a lambda-system are resonant with their respective transitions, the atomic polarizations are very sensitive to an applied magnetic field. This effect can be used for optical magnetometry. The degree of sensitivity of the magnetometer is determined by two competing parameters–atomic density and laser intensity. It is shown experimentally that the optimal sensitivity reaches saturation, which is contrary to the idea that sensitivity increases indefinitely with an increase in the above parameters.

Parametric equations are used to represent the pathway of an object in terms of time or another changing variable. This allows, for example, for equations that are written using two variables to be examined in terms of the passage of time. In this paper the author examines two traditional application problems whose solutions can be enriched through the use of parametric equations. In the first, the falling ladder problem, a ladder is leaned against a wall then pulled away with a constant velocity. Deriving parametric equations for this scenario permits the pathway of the ladder to be plotted. Parametric equations also make it possible for the horizontal and vertical velocities of the ladder to be examined separately. The second problem is that of maximizing the length of a ladder that can fit around a hallway corner. In this problem an envelope algorithm is first developed, then parametrized to further investigate this scenario. Using these two situations, this report ultimately shows how parametric equations can be used to give a more thorough approach to some of today’s most classic calculus problems. / text

In practice there is a long tradition of actuaries calculating reserve estimates according to deterministic methods without explicit reference to a stochastic model. For instance, the chain-ladder was originally a deterministic reserving method. Moreover, the actuaries often make ad hoc adjustments of the methods, for example, smoothing of the chain-ladder development factors, in order to fit the data set under analysis. However, stochastic models are needed in order to assess the variability of the claims reserve. The standard statistical approach would be to first specify a model, then find an estimate of the outstanding claims under that model, typically by maximum likelihood, and finally the model could be used to find the precision of the estimate. As a compromise between this approach and the actuary's way of working without reference to a model the object of the research area has often been to first construct a model and a method that produces the actuary's estimate and then use this model in order to assess the uncertainty of the estimate. A drawback of this approach is that the suggested models have been constructed to give a measure of the precision of the reserve estimate without the possibility of changing the estimate itself. The starting point of this thesis is the inconsistency between the deterministic approaches used in practice and the stochastic ones suggested in the literature. On one hand, the purpose of Paper I is to develop a bootstrap technique which easily enables the actuary to use other development factor methods than the pure chain-ladder relying on as few model assumptions as possible. This bootstrap technique is then extended and applied to the separation method in Paper II. On the other hand, the purpose of Paper III is to create a stochastic framework which imitates the ad hoc deterministic smoothing of chain-ladder development factors which is frequently used in practice.
