This report is about film making, wich parts that are included in film making and things that is good to think of when doing film for the first time. A short movie has been created and from this, this study has been done to figure out if the theory is like the reality. Also the report is based om the book ”How to get started in film making” by Tom Holden and interviews with people working with film.

Laparoscopic liver surgery is mainly preferred over the traditional open liver surgery due to its unquestionable benefits. This type of surgery is executed by inserting an endoscope camera and the surgical tools inside the patient’s body through small incisions. The surgeons perform the operation by watching the video transmitted from the endoscope camera to high-resolution monitors. The location of the tumors and cysts is examined before and during the operation by the surgeons from the pre-operative CT scans displayed on a different monitor or on printed copies making the operation more difficult to perform. In order to make it easier for the surgeons to locate the tumors and cysts and have an insight for the rest of the inner structures of the liver, the 3D models of the liver’s inner structures are extracted from the preoperative CT scans and are overlaid on to the live video stream transmitted from the endoscope camera during the operation, a technique known as virtual X-ray. In that way the surgeons can virtually look into the liver and locate the tumors and cysts (focus objects) and also have a basic understanding of their spatial relation with other critical structures. The current master thesis focuses on enhancing the depth and spatial perception between the focus objects and their surrounding areas when they are overlaid on to the live endoscope video stream. That is achieved by placing a cone on the position of each focus object facing the camera. The cone creates an intersection surface (cut volume) that cuts the structures that lay in it, visualizing the depth of the cut and the spatial relation between the focus object and the intersected structures. The positioning of the cones is calculated automatically according to the center points of the focus objects but the sizes of the cones are user defined with bigger sizes revealing more of the surrounding area. The rest of the structures that are not part of any cut volume are not discarded but handled in such way that still depict their spatial relation with the rest of the structures. Different rendering results are presented for a laparoscopic liver test surgery in which a plastic liver model was used. The results include different presets of the cut volumes’ characteristics. Additionally, the same technique can be applied on the 3D liver’s surface instead of the live endoscope image and provide depth and spatial information. Results from that case are also presented.

For better understanding of how users interact with the video on demand service Netflix a study was conducted in 10 Swedish households. This study is based on the well-established heuristic evaluation method of Jacob Nielsen, which we modified slightly by letting the users to act as “evaluation experts” and informing them about the heuristic rules of thumb during the evaluation process. The purpose of this study was to identify usability problems when people interact with Netflix’ interface. We found that the users identified usability problems efficiently and that the information they delivered might be useful for further development of Netflix and other video on demand services. The modified application of Nielsen’s rules of thumb seems to have worked satisfactorily.

When I worked with the daily communication with the lottery’s customers on social media the Communications Department at Nova Media Swedish Postcode Lottery contacted me to write a document, plan and present an advertising campaign in their social media channels to Christmas 2014. The company had ideas on a campaign that they wanted develop where my job was to develop and present a plan for how to implement the campaign. The purpose is to explain what PostkodTomten is and to highlight its commercial advantages for marketing purposes. To have succeeded with this work, I needed a clear methodology and plan. I deepened my knowledge in marketing with a clear focus on social media, literary studies has been key and theoretical studies have been a good basis to implement my work practically. The conclusion I take with me in the future, the importance of how to dispose of your work, meetings booked weekly and milestones were set up giving the project good order and structure. This report will first and foremost focus and process these documents but also contains a theoretical part of marketing and communications in social media in general. The document and the report were presented to the company as an appendix. The theoretical parts of the report focuses on the marketing and communications in social media, how it is going to and how to do it appropriately. It is also up to what a company can do to strategically "stick out" and promote themselves on social media and its various channels. The terms "Buzz marketing" and "viral marketing" will also be explained.

This study aims to examine two user groups experience and usage of the mobile job advertising service Uptrail. The two groups that are the focus of this work are the companies that use the service for job recruitment and job-seekers that have applied for work through Uptrail. In which context job-seekers apply for work through the service and why is also examined in this study. This is to give an understanding of how the mobile interface might influence users behaviour during the job recruitment process. The study is based on a qualitative research method where individual in-depth interviews with representatives from the different groups are used for gathering data. Also a shorter observation has been applied during the interviews with the job seekers. Collected data were then analyzed through an inductive interpretation method and combined with previous research and theories regarding mobile usage, context, digital recruitment (e-recruitment) and user experience (UX). The result of the study implies that Uptrail has impacted the motives behind job advertising by affecting the user experience of the recruitment process. Job applicants experienced that the mobile format and the process of the service changed their habits on applying for work through digital application. In line with previous research results from this study also suggest that the usage of mobile services largely takes place in “home like” environments. This is explained as a consequence of existing attitudes and thoughts regarding the job search process.

In 2017 social media network Facebook launched a new mission that aim to bring people and the world closer together via Facebook groups. In contrast to this mission, recent years of research indicate that social media as Facebook increases social divisions. This paper investigate how successfully Facebook groups with the official purpose to bring people together and build friendships works. The study was conducted through a survey posted in five Facebook groups with this specific aim. The result show that people are far more willing to request new friendships than reply other members requests of new friendships. Ever thought the large majority said they wore member of the group to find new friends, the majority also responded they had not found new friends via the group. The result is analyzed and discussed based on theories of homogeneity, social identity theory, self representation and previous kindred research of this paper.

This thesis addresses the question of how a scalable, distributed teamwork environment should be designed and realized. Central design criteria includes that the system should be scalable and robust, allow for easy access and be symmetric. The system should allow for project team members to collaborate even though they are not located at the same physical location. The resulting system presented in this thesis, called the mStar environment have been created to address exactly these questions. mStar is scalable and robust through the usage of standard networks and IP-multicast, it allows for easy access as it is desktop based and finally it is symmetric allowing for easy peer-communication. mStar includes support for desktop conferencing, including mAudio for audio, reuse of the MBone Vic tool for video, mWB for whiteboard, mChat for text based chat and mVote for voting. It also supports distributed synchronized presentations using the WWW and the mWeb application. As all traffic is network and IP-multicast based it allows for easy recording and playback of teamwork sessions using the mMOD application. To allow for easy access to users behind non-multicast capable network segments (primarily modem and ISDN), mTunnel was created. It allows for tunneling and transformation of the traffic. Another member of the mStar environment is Director for remote control of video equipment. mStar also includes support for easy creation of new teamwork tools and applications using the Tunable Multicast Platform - /TMP and the Generic Agent Architecture. The mStar environment can be used and is being used on a daily basis for electronic meetings, distance education and lectures, and daily teamwork. The usage mStar creates group awareness between project members and helps users from not becoming isolated from their department and project team. mStar allows for usage 24 hours a day and have resulted in, among other things, a new usage patterns, which resembles electronic corridors more than specific meetings, where users can and do meet spontaneously to talk about anything they want, but also overhear other interesting and important conversations just as in a physical office corridor. / Godkänd; 1997; 20061004 (ysko)

Public use of the Internet increases as wideband connections become pervasive and applications suitable for media distribution grow popular. Group collaboration applications have attracted interest during recent years. Wireless connectivity and business applications also furthers a need for reliable communication protocols. Multicast is a driving force for new applications involving one-to-many as well as many-to-many user scenarios like lecturing, discussions, and collaborative work. In some applications guaranteed delivery of every packet is not crucial, while in other this is a requirement. Error handling in reliable protocols can present a substantial challenge already in a homogeneous environment. Including a plethora of end-user terminal types with widely varying resources it becomes even more challenging. Protocols and applications must therefore be able to handle receiver and network link heterogeneity. The thesis addresses some of the challenges facing the applications in this field, related to multicast and unicast alike. Although the obstacles each of them must overcome may differ, there are similarities with regards to possible solutions with respect to error handling or resource allocation. Error handling protocols are proactive or reactive. Proactive protocols transmit redundant information along with the original information, enabling the receivers to repair lost packets without feedback to the sender. Reactive protocols rely either on positive or negative feedback from the receivers in order to establish reliability. According to a definition of semantic reliability the reliability concept can be interpreted in terms of application semantics. It is proposed to view reliable multicast as a special case of semantically reliable multicast and to implement a dynamically configurable transport layer with an error-handling rule set that can be configured from the application or even from the sender in- session. It is also proposed to make use of the application's knowledge of specific semantics to improve on the recovery of lost packets, congestion handling, or resource allocation. The thesis also presents a bandwidth-sharing scheme for video in group collaboration using application semantics in the form of user hints. The presence of such events is made available to all senders via message passing between session members. As information relating to a user's interest in another user is conveyed, the sender may increase its use of resources on the expense of other senders. A scheme is proposed and a prototype implementation and experimental results are presented. / <p>Godkänd; 2003; 20060918 (ysko)</p>

This thesis presents a system for real-time large scale distributed music distribution, such as radio on the Internet. The existing technologies do not enable the full potential that broadcast media on the Internet can give, such as a very large number of interactive receivers. A technology that can help achieve potential is IP-multicast, which enables broadcast applications to scale to millions of receivers. However, IP-multicast creates new problems that have to be solved for it to be used on the Internet; some of these problems are addressed in this thesis. The system presented in this thesis, mIR - multicast Interactive Radio, has been used as a prototype to implement and examine different solutions to some of the issues of IP-multicast and real time music distribution. These are problems such as heterogeneity, reliability and security. Heterogeneity and reliability are different aspects of the same problem: that IP-multicast is an unreliable Internet transport mechanism. In this thesis different methods for avoiding these problems are described and evaluated. Security in the context of IP-multicast has many aspects. While the problems of confidentiality and authentication have been extensively examined, there are still a few unresolved problems. One of these problems is traitor tracing: how to know the origin of illegal copies of a media object such as a radio transmission. An application of digital watermarking, fingerprinting, can be used to distinguish between different copies of the same media object, but requires that each copy is individually marked. This contradicts the basic property of multicast that ensures its scalability: that everyone receives exactly the same data. We show how we can combine the different goals of fingerprinting and IP-multicast while still maintaining the scalability features of multicast. / <p>Godkänd; 2001; 20070313 (ysko)</p>
