Abstract  Background: E-commerce and omni-channel retailing strategies have emerged with digitalization. Digital channels have affected many parts of the daily life for consumers and as a result the consumer’s decision-making processes have become more complex. Born natives are a generation of consumers that have grown up having access to digital technology and their behaviors form a unique phenomenon as consumers within the omni-channel environment. At the same time, continuous growth in the Swedish furniture industry has allowed for new retailing strategies to emerge. The sample of born natives born during the 1990’s provides a unique insight in how these consumers behave and interact in the Swedish omni-channel furniture retailing environment.  Research question: How does the omni-channel retailing environment affect decision-making Purpose: The purpose of this study is to explore how digital native consumers who now comprise a larger consumer segment on the furniture market perceive the omni-channel environment in addition to how the digital omni-channel environment affects their decision- making process when it comes to furniture purchases in terms of perceived risks, purposes, and consumer benefits.  Methodology: This study is of qualitative nature which approaches the research problem and purpose with a relativistic philosophical stance. Semi-structured interviews were conducted to provide relevant data by individual consumers, and which have been analyzed with a hermeneutical approach. An inductive approach was adopted to explore the phenomenon.  Conclusion: Consumers perform multiple different actions and adopt different behaviors when operating in the furniture omni-channel retailing environment. Risk aversion, identity building, entertainment and channel selection are all aspects of furniture shopping that are impacted by digital natives operating in the omni-channel retailing environment.

Customers uses both offline and online channels before the final purchase, retailers that are operating and selling their products both online and offline can benefit from aligning the experiences on their channels by using an omni-channel strategy. The smartphone is becoming a natural part of our day-to-day life and keeping us connected, also when visiting abrick and mortar retailers. Mobile technology therefore possesses the opportunity to integrate in-store experience with the online world for creating value for customers. But many retailers are struggling in their integration efforts towards an omni-channel strategy due toall the possible technologies to invest. Therefore, the purpose of this thesis was to investigate the acceptance of mobile technologies in a brick and mortar retail setting, the chosen technologies are beacons and augmented reality.This research investigated the mediating effect of the four technology readiness dimensions:optimism, innovativeness, discomfort and insecurity, on the constructs of the technology acceptance model: perceived usefulness and perceived ease of use. The research was carried out with a positivist research philosophy, inductive approach and lastly with an explanatory research design including a quantitative method. The data was collected through a survey, which got answered by 224 participants. The data was further statistically analyzed. The result showed that several of the dimensions of technology readiness had a significant effect on the constructs of technology acceptance model, especially the dimension: optimism. Thus, retailers that wants to introduce mobile technology into their stores should put emphasis on customizing their offerings towards the customers’ different level of technology readiness, especially optimism.

The development of digital solutions has changed the way consumers complete purchases today. New distribution channels through internet and mobile applications have come to challenge the business of traditional retailers. Thus, retailers must find new ways of keeping customers loyal to the store. One way of retaining customers is to provide a more prominent customer experience. This study focuses on technological solutions for the food retail industry that enables the creation of this experience, more specifically self-scanning applications provided by the Swedish company Datema.The Swedish market, in which Datema acts, is among the most technologically advanced in the world regarding self-scanning solutions and has begun to reach a maturity phase. This, along with desires to expand the marketplace, has created an attraction to larger foreign markets such as North America. Similarities in business culture and a strong buying power have led to a certain interest in the Northeastern part of America. Thus, the purpose of this thesis is to investigate the need for self-scanning solutions in this specific area and to provide recommendations for how the market could be targeted.To create an overview of the market structure the consumer market has been studied through an in-depth literature review of the latest market investigations. Furthermore, the technological level of Northeastern supermarket chains was investigated through market observations and interviews with store managers in Boston, Massachusetts. To create the holistic view of the market, interviews with experts in the US retail market and with US IT-vendors were conducted. Additionally, interviews with management consultants and experts in market entries have contributed to answering the question of how the market should be entered. Finally, in order to provide conclusions and recommendations, the results have been analyzed with relevant literature and theories within marketing, change management and entry mode management.The findings in this master thesis indicates that there is a need for technological solutions that enhance the customer experience in the Northeastern American food retail market. Furthermore, the technological level of the existing supermarket chains in Boston is considered low and that the level and acceptance varies with the store concept. The previous resistance towards implementation of new technological solutions in the stores was found to mainly depend on a low knowledge, low trust in the consumers and fear of losing customer interaction.Datema is recommended to address the middle and high-end supermarket chains with a follower approach. Further recommendations include that the market should be entered through a joint venture with a local partner.

Arabic text recognition was not researched as thoroughly as other natural languages. The need for automatic Arabic text recognition is clear. In addition to the traditional applications like postal address reading, check verification in banks, and office automation, there is a large interest in searching scanned documents that are available on the internet and for searching handwritten manuscripts. Other possible applications are building digital libraries, recognizing text on digitized maps, recognizing vehicle license plates, using it as first phase in text readers for visually impaired people and understanding filled forms. This research work aims to contribute to the current research in the field of optical character recognition (OCR) of printed Arabic text by developing novel techniques and schemes to advance the performance of the state of the art Arabic OCR systems. Statistical and analytical analysis for Arabic Text was carried out to estimate the probabilities of occurrences of Arabic character for use with Hidden Markov models (HMM) and other techniques. Since there is no publicly available dataset for printed Arabic text for recognition purposes it was decided to create one. In addition, a minimal Arabic script is proposed. The proposed script contains all basic shapes of Arabic letters. The script provides efficient representation for Arabic text in terms of effort and time. Based on the success of using HMM for speech and text recognition, the use of HMM for the automatic recognition of Arabic text was investigated. The HMM technique adapts to noise and font variations and does not require word or character segmentation of Arabic line images. In the feature extraction phase, experiments were conducted with a number of different features to investigate their suitability for HMM. Finally, a novel set of features, which resulted in high recognition rates for different fonts, was selected. The developed techniques do not need word or character segmentation before the classification phase as segmentation is a byproduct of recognition. This seems to be the most advantageous feature of using HMM for Arabic text as segmentation tends to produce errors which are usually propagated to the classification phase. Eight different Arabic fonts were used in the classification phase. The recognition rates were in the range from 98% to 99.9% depending on the used fonts. As far as we know, these are new results in their context. Moreover, the proposed technique could be used for other languages. A proof-of-concept experiment was conducted on English characters with a recognition rate of 98.9% using the same HMM setup. The same techniques where conducted on Bangla characters with a recognition rate above 95%. Moreover, the recognition of printed Arabic text with multi-fonts was also conducted using the same technique. Fonts were categorized into different groups. New high recognition results were achieved. To enhance the recognition rate further, a post-processing module was developed to correct the OCR output through character level post-processing and word level post-processing. The use of this module increased the accuracy of the recognition rate by more than 1%. / King Fahd University of Petroleum and Minerals (KFUPM)

I vårt allt mer digitaliserade samhälle har internet fått en central roll, och har förändrat många aspekter i vårt vardagsliv. Ett av de områden som påverkats starkt av denna utveckling, är den svenska detaljhandelns e-handelsmarknad. De senaste 10 åren har dess omsättning sexdubblats, och prognoser tyder på att denna expansiva trend kommer att hålla i sig. Detta innebär helt nya förutsättningar för de svenska detaljhandelsföretag som tidigare bara bedrivit försäljning i fysiska butiker, eller bedrivit e-handelsverksamhet i liten skala. Ämnet för denna studie föreslogs av den svenska detaljhandelskedjan Företag X[1], som har beslutat att lansera en e-handel i början av år 2016. Företag X föreslog att författaren skulle kartlägga vad som krävs för att gå från en liten nyetablerad e-handel, till en stor och framgångsrik e-handel som bidrar till företagets lönsamhet och fortsatta välmående. Studiens syfte är således att kartlägga praxis och metoder som möjliggör framgångsrik expansion av e-handeln för medelstora, svenska detaljhandelsföretag. För att uppnå syftet valdes en kvalitativ multifallstudie-design. Information till den teoretiska referensramen samlades in från vetenskapliga artiklar och böcker, och kompletterades med sekundärempiri i form av rapporter från företag. Kvalitativ primärdata samlades sedan in från intervjuer med tre fallföretag, som hittades genom en mindre tvärsnittsstudie av 20 konkurrenter till Företag X där företagens EBITDA-marginal de senaste fem åren studerades.   Studiens resultat visade att den svenska detaljhandelns e-handelsmarknad har sett en mycket expansiv trend de senaste åren, och att denna ser ut att hålla i sig under det kommande decenniet. Detta innebär att marknadsklimatet håller på att förändras och går mot att bli allt mer digitalt, vilket kräver att företagen ser över sina försäljningsorganisationer. Den största trenden på marknaden kallas ”omnikanalhandel”, och innebär i korthet att företaget integrerar sin butiks- och e-handelsförsäljning för att möjliggöra en sömlös köpupplevelse för kunden. Denna trend har framträtt som ett svar på ett nytt köpmönster som noterats bland kunderna, där dessa rör sig mellan företagens digitala och fysiska försäljningskanaler under köpresan. Studien pekar på att de e-handelsrelaterade frågor som är viktigast att adressera och arbeta med finns inom följande områden: KundfokusIT Kundrelationer Lyhördhet mot kund KostnadseffektivitetSupply chain och logistik Strategi och styrning MotståndshanteringUtbildning Samspel med butiker Studien utgör författarens examensarbete i utbildningen Industriell Ekonomi vid Linköpings Tekniska Högskola.   [1] Företag X heter egentligen något annat, men har bett att få vara anonyma i denna studie. / The Internet has become a central part of the modern society and has change our everyday life in many ways. An area that’s been strongly affected by this development is the Swedish retail e-commerce market. E-commerce sales have increased six-fold over the course of the past decade and forecasts indicate that this expansive trend will continue. This trend places significant challenges on Swedish retail companies who have a legacy of exclusively carrying out their sales in the traditional brick and mortar format. The subject of this study was originally proposed by the Swedish retail company Företag X[1], who have decided to embark on their e-commerce initiative in early 2016. Företag X asked the author of this report to help with finding out what it takes to develop a small e-commerce store, in such a way that it becomes a successful part of the company, contributing to the company’s overall profitability. The purpose of this study is therefore to identify practices and methods that enable successful expansion of e-commerce for medium-sized, Swedish retail companies. In order to achieve the purpose, a qualitative multi-case study design was chosen for the study. Information for the theoretical framework was collected from articles in scientific journals and books, and supplemented with secondary empirical data in the form of reports from companies. Qualitative primary data were then collected from interviews with three chosen companies, which were found with through a small cross-sectional study of 20 competitors to Företag X where their EBITDA margins over the past five years were studied. The study results showed an expansive trend on the Swedish retail e-commerce market, and it seems that this trend is set to continue over the next decade. As a consequence, market climate is changing and shifting towards becoming more digitalized, which requires companies to review their sales organizations. The main trend in the market is called “omni-channel retailing" and means that a company is integrating its brick and mortar and e-commerce sales to enable a seamless shopping experience for the customer. This trend has emerged as a response to a new buying patterns observed among customers, who move between their digital and physical sales channels during the purchase. The study indicates that the e-commerce-related issues that are most important to address and work with are in the following areas: Customer FocusIT Customer relations Responsiveness to customers Cost effectiveness Supply chain and logistics Strategy and governance Resistance ManagementEducation Synchronization between brick and mortar stores and e-commerce store This study represents the author’s master’s thesis in the Industrial Engineering and Management program at Linköping University, Sweden.

Long-term omni-directional ambient noise was collected at several sites in the Gulf of Mexico during 2004 and 2005. The Naval Oceanographic Office deployed bottom moored Environmental Acoustic Recording System (EARS) buoys approximately 159 nautical miles south of Panama City, Florida, in water depths of 3200 meters. The hydrophone of each buoy was 265 meters above the bottom. The data duration ranged from 10-14 months. The buoys were located near a major shipping lane, with an estimated 1.5 to 4.5 ships per day passing nearby. The data were sampled at 2500 Hz and have a bandwidth of 10-1000 Hz. Data are processed in eight 1/3-octave frequency bands, centered from 25 to 950 Hz, and monthly values of the following statistical quantities are computed from the resulting eight time series of noise spectral level: mean, median, standard deviation, skewness, kurtosis and coherence time. Four hurricanes were recorded during the summer of 2004 and they have a major impact on all of the noise statistics. Noise levels at higher frequencies (400-950 Hz) peak during extremely windy months (summer hurricanes and winter storms). Standard deviation is least in the region 100-200 Hz but increases at higher frequencies, especially during periods of high wind variability (summer hurricanes). Skewness is positive from 25-400 Hz and negative from 630-950 Hz. Skewness and kurtosis are greatest near 100 Hz. Coherence time is low in shipping bands and high in weather bands, and it peaks during hurricanes. The noise coherence is also analyzed. The 14-month time series in each 1/3- octave band is highly correlated with other 1/3-octave band time series ranging from 2 octaves below to 2 octaves above the band's center frequency. Spatial coherence between hydrophones is also analyzed for hydrophone separations of 2.29, 2.56 and 4.84 km over a 10-month period. The noise field is highly coherent out to the maximum distance studied, 4.84 km. Additionally, fluctuations of each time series are analyzed to determine time scales of greatest variability. The 14-month data show clearly that variability occurs primarily over three time scales: 7-22 hours (shipping-related), 56-282 hours (2-12 days, weather-related) and over an 8-12 month period.

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.
