Detaljhandeln har förändrats i och med digitaliseringens framfart. Teknikens utveckling tillsammans med en större andel uppkopplade konsumenter innebär nya försäljnings- och marknadsföringskanaler för detaljhandlare. Detta har medfört att detaljhandelsföretag ställs inför krav av att integrera de olika kanalerna med varandra vilket inom forskningen benämns som en omnikanalstrategi. Syftet med studien har varit att, ur ett företagsperspektiv, undersöka hur svenska detaljhandelskedjor arbetar med att integrera digitala och fysiska försäljnings- och marknadsföringskanaler. Detta för att erhålla en bättre förståelse för fenomenet omnikanal och hur företag går tillväga för att integrera kanalerna med varandra. Studien ämnar bidra med kunskap kring hur företag kan skapa en enhetlig upplevelse mellan sina olika kanaler. I studien har en kvalitativ forskningsmetod tillämpats där semistrukturerade intervjuer genomfördes med detaljhandelsföretag som arbetar med omnikanaler. De företag som medverkade i studien var Cervera, Elgiganten, Gina Tricot, Kappahl, Kicks, Lyko, Netonnet och Royal Design. Resultatet av studien påvisar flera aspekter gällande hur detaljhandelsföretag kan integrera de digitala och fysiska försäljnings- och marknadsföringskanaler med varandra samt dess utmaningar och möjligheter. En modell har även tagits fram, vilken består av fyra gemensamma grundläggande steg gällande att skapa en enhetlig upplevelse mellan kanalerna. De fyra stegen som identifierats är: nulägesanalys, identifiering av kundresan, skapa konsensus samt integrera system. / The retail industry has changed with the advance of the digitalization. The development of new technology and consumers who are continuously connected online implicate new sales and marketing channels for retailers. This imply that retail companies face the requirement of integrating the different channels with each other, which in research is called an omni-channel strategy. The purpose of the study has been, from a management perspective, to investigate how Swedish retail chains work to integrate both digital and physical sales and marketing channels. This to obtain a better understanding of the phenomenon omni-channel and how companies integrate the channels. The study aims to provide knowledge for how companies can create a unitary experience between their different channels. The study applied a qualitative research method in which semi-structured interviews were conducted with Swedish retail chain companies that has an omni channel strategy. The companies that participated in the study were: Cervera, Elgiganten, Gina Tricot, Kappahl, Kicks, Lyko, Netonnet and Royal Design. The results of the study show several aspects regarding how retail companies can connect their digital and physical sales and marketing channels with each other but also which challenges and opportunities there is. A model has been developed showing four common basic steps to create a unitary experience between the channels. The four steps are: status rapport, customer journey identification, creating consensus and integrating systems.

Omni-directional (O-D) infrared (IR) vision is an effective capability for mobile systems in robotics, due to its advantages: illumination invariance, wide field-of-view, ease of identifying heat-emitting objects, and long term tracking without interruption. Unfortunately, O-D IR sensors have low resolution, low frame rates, high cost, sensor noise, and an increase in tracking time. In order to overcome these disadvantages, we propose an autonomous system application in indoor scenarios including 1) Dynamic 3D Reconstruction (D3DR) of the target view in real time images, 2) Human Behavior-based Target Tracking from O-D thermal images, 3) Thermal Multisensor Fusion (TMF), and 4) Visual Perception for Social Cognition from the motion behavior of the human target.

This thesis deals with the design of a three-wheeled omni-directional robot control. The model of control is designed for robot´s omni-directional platform driven by maxon motor with the intelligent positioning controller EPOS. The design of control contains: - installation of the coordinated systems and transformation from one of them into another - design of system´s kinematical model - creation of classes for control and communication with EPOS - creation of the simulative program - planning of the mobile robot´s path - verification that the system is working The solution was based on continuous accelerated motion and the maximal acceleration of wheels was concerned, so that the slip would be suppressed. The function of the model was partly verified.

This cumulative dissertation consists of four papers that investigate retailer switching and identify potential and threat of cross-channel retail services (CCRS) for retail businesses. The first, conceptual paper compares different theories and models of retail quality. It derives the concept of retailer aspects as a framework to measure retailer quality and further discusses how CCRS can serve as a tool to enhance those retailer aspects. The second paper discusses results from a consumer panel survey and quantifies the influence of satisfaction with retailer aspects on retailer switching during webrooming behavior. The findings of this second paper present the two retailer aspects assurance of delivery and competitive product pricing as key determinants for retailer switching. The third paper defines CCRS and outlines a conceptual classification scheme for CCRS assessments – the CCRS Pentagon. The fourth paper quantifies the impact of CCRS adoption and retailer aspect preferences on CCRS-induced retailer switching based on a second consumer panel survey. Results from this second study affirm the existence of CCRS-induced retailer switching. The paper concludes that CCRS can serve as a retailer’s lock-in mechanism, but that the availability of CCRS in retail environments also threatens retail businesses. In sum, the dissertation provides academic contributions and suggestions for further academic research as well as practical implications and management tools for application in retail businesses.:I.

Background: E-commerce for groceries is growing and growing in Sweden and pure ecommerce companies are constantly entering the market. This study is based on Ica, which for a long time has been successful in the physical market through decentralization and the Ica-idea with individual retailers incollaboration and physical stores. To meet the new type of consumer behavior and competition Ica has developed a number of e-commerce solutions. Including the phenomenon of dark stores that indicates a new type of centralization within the group. Purpose: The purpose of this study is to analyze the experienced opportunities and limitations of a retailer-owned franchise organization in the Swedish grocery trade in its development work of e-commerce. A further purpose is to shed light on the interviewees reasoning about whether dark stores are a sustainable solution from a competitive and relational perspective. Method: In this study, a qualitative research strategy is applied in a case study design. The empirical data is generated through semi-structured interviews with managers and retailers from Ica stores in the Stockholm region and the ecommerce manager for Ica Sweden. The empirical data has then been codedand divided into four themes with associated subcategories. Literaturestudy: For the essay a literature study presenting theories and previous research on centralization and decentralization, vertical and horizontal integration, click-and-mortar, omni channels and competition was made. Afterwards it´s used as a basis for the theoretical comparison in the analysis part. Conclusion: Due to the ownership structure, the case organization is facing some unique conditions. Example, the decentralized power promotes quickness and opportunities for local adaptations, but also that a pure e-commerce modelwould be problematic. One solution the head office has developed is a dark stores service that the stores can use, which gives them access to a larger geographic market and leads to higher internal competition between thestores.

Namely, mapping the sphere to a plane introduces stretching of the spherical image content, and requires at least one seam in the image to be able to unwrap the sphere. Generative neural networks have shown impressive ability to synthesize images, but generating spherical images is still challenging. Without specific handling of the spherical topology, the generated images often exhibit distorted contents and discontinuities across the seams. We describe strategies for mitigating such distortions during image generation, as well as ensuring the image remains continuous across all boundaries. Our solutions can be applied to a variety of spherical image representations, including cube-maps and equirectangular projections.</p><p dir="ltr">A closely related problem in generative networks is 3D-aware scene generation, wherein the task involves the creation of an environment in which the viewpoint can be directly controlled. Many NeRF-based solutions have been proposed, but they generally focus on generation of single objects or faces. Full 3D environments are more difficult to synthesize and are less studied. We approach this problem by leveraging omnidirectional image synthesis, using the initial features of the network as a transformable foundation upon which to build the scene. By translating within the initial feature space, we correspondingly translate in the output omnidirectional image, preserving the scene characteristics. We additionally develop a regularizing loss based on epipolar geometry to encourage geometric consistency between viewpoints. We demonstrate the effectiveness of our method with a structure-from-motion-based reconstruction metric, along with comparisons to related works.</p>

Planar antennas are used in several technical applications. The family of planar antennas contains microstrip antennas, which are very popular due to the low weight, low profile, simple manufacturing and easy mass production. Lower gain and excitation of surface waves are disadvantages of microstrip antennas. The propagation of surface waves can be efficiently suppressed if the conventional substrate is replaced by an electromagnetic bandgap (EBG) substrate. Microstrip antennas on EBG substrates have been presented in an open literature for several years. Nevertheless, no published work is devoted to the design of EBG substrates, which can suppress surface waves at several frequencies those cannot be covered by a single bandgap. In order to reach optimum parameters of designed antennas, selected global optimization methods are applied (genetic algorithms, particle swarm optimization, ant colony optimization).
