M. Tech. Electronic Engineering. / Monitoring manufacturing plants, military surveillance or enhancing audio signals in a noisy environment are few of the many applications that can benefit from acoustic signal localization. The objective of the project is to design a system that is able to locate an acoustic source using a linear array of omni-directional microphones. The signal outputs of the array are fed into a PC, which processes the data, using a MATLAB-based program. The acoustic source is considered to be unique and stationery. The location of the source will be done by determining the Direction of Arrival (DOA) of the audio signal. This research does not tackle the issue of determining the distance between the source and the array of microphones. "Beamforming" methods are implemented to determine the DOA. The conventional "beamforming" method was compared with higher resolution techniques such as adaptive filtering. Computer simulations of the algorithms were performed, followed by practical experiments. A Field Programmable Gate Array (FPGA) was used to enable a real time acquisition of signals from an array of microphones and the communication interface to the PC was accomplished via the USB interface. The results show that the system can detect the direction of arrival properly and provide the user with lower signal to noise ratio (SNR) reconstructed signals.

Since internet was born digitalization has flourished and led to technological innovations that opened up new opportunities on the market. In the retail sector, the digitalization and development of mobile devices, tablets and social media have changed the traditional trade both online and in physical stores. In order to cope with the challenge of digitalization and to meet consumers' new expectations, more companies have begun offering customers a seamless customer experience between physical and digital stores, called omnichannel. Omnichannel represents a very favorable opportunity for companies to exploit synergies between channels to synchronize interactions with consumers across multiple channels. The purpose of this paper is to investigate perceptions of the link between omnichannel strategy and consumers trust. Since the purpose of the study is to increase understanding of perceptions about the connection between omnichannel strategy and consumer trust, we have chosen a qualitative research method. Our empirical evidence was collected through six interviews with experts in the field of omnichannel and people that have experience of omnichannel as a strategy. The result shows that respondents perceive that companies can use different channels to create trust, but different channels have different conditions. For example, it is harder to build trust through digital channels if they are not linked to a physical store. Omnichannel can therefore create synergies in which the company can benefit from each channel's trust-making features. However, respondents perceive that omnichannel is very difficult to organize and can create major problems for companies unable to handle this integration of the channels.

This study examined the signaling strength, or marketing power, of the most common qualifications of entry-level biomedical equipment technicians (BMETs) in Texas, based on stated hiring preferences of BMET managers, using order ranking of fictitious resumes. This study also sought to determine whether certification status, education background, military training background as a BMET, or type of employer [hospital or ISO] of the hiring manager had an effect on hiring preference for applicant qualifications of associate degree, military training as a BMET, or certified biomedical equipment technician (CBET) certification candidacy. Participants were asked to rank 16 fictitious resumes representing the most common qualifications of entry-level BMETs and to fill out a background questionnaire regarding their education, military, certification, and employer. The number of times each resume ranked in first place was tabulated and inter-rater reliability was calculated. Resumes with qualifications of associate degree versus military training as a BMET were compared at three levels of work experience. A chi-square test for independence was conducted for the comparisons to determine whether work experience influenced preference. Chi-square tests were also conducted for comparisons of associate degree with candidacy for CBET certification versus associate degree and military training with CBET candidacy versus military training. No statistically significant results were found for the chi-square tests, indicating that work experience did not significantly influence participant preferences for the compared qualifications. BMET hiring managers indicated a preference for combinations of qualifications rather than any single qualification. Correlations in hiring managers' educational background, certification status, military training as a BMET, type of employer, and preference for applicant qualifications were examined. Statistically significant correlations were found between participants' preference for associate degree or military training and level of education, military training background, and type of employer. Statistically significant correlations were also found between participants' preference of military training with CBET candidacy over military training alone and military training as a BMET background as well as certification background.

Studien besvarar vilka typer av kommunikationsstrategier som är mest relevanta för att företag ska kunna påverka och förmedla kunskap om hållbar konsumtion. Studien utgår från signalteori och informationsasymmetri för att tydligt visa vilka strategier som är bäst för företag att använda sig av för att kommunicera externt. De strategier som studien tar upp är certifieringar, standarder & miljörevision, hållbarhetsredovisning & GRI, samarbete & FN:s globala hållbarhetsmål och slutligen miljömärkningar. Studien visar att samtliga strategier är en förutsättning för att företag ska kunna påverka och kommunicera ut kunskap om hållbar konsumtion samt att framhålla ett mer trovärdigt hållbarhetsarbete. Det framkom att de fyra undersökta företagen använde sig mer eller mindre av samtliga strategier men att inget av företagen använde sig av extern revision vilket skulle kunna hjälpa dem att öka trovärdigheten i sin kommunikation. / The study investigates which kind of communication strategies companies use to affect and to convey knowledge about a sustainable consumption. The study is based on signal theory and information asymmetry to clearly show which strategies are best for companies to use to communicate externally. The strategies included in the study are certifications, standards & environmental audit, sustainability report & GRI, cooperation & UN sustainable development goals and finally ecolabelling. The study shows that all strategies are a prerequisite for companies to influence and communicate knowledge about sustainable consumption; Furthermore, give more credible sustainability work. It turned out all four companies used more or less of all strategies, but none of the companies used external auditing, which could help them achieve more trustworthy communication.

Syftet med denna uppsats är att med hjälp av lämpliga teorier och intervjuer med företag erbjuda en förståelse kring hur företag använder Corporate Social Responsibility i deras rekryteringsprocess samt hur innehållet används för att påverka företagets image som arbetsgivare
