International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The older F16 jet fighters are currently being flight tested to evaluate the upgraded electronics for aircraft avionics, flight control and weapons systems. An instrumentation system capable of recording three different video signals, recording four Military- Standard-1553B (Mil-Std-1553B) data streams, recording one PCM stream, transmitting the PCM stream, and transmitting two video signals was needed. Using off the shelf equipment, the F16 instrumentation system was design to meet the electronic specifications, limited available space of a small jet fighter, and limited space in the SBand frequency range.

International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / This paper describes the design and characteristics of a digital voice encoding circuit that uses the continuously variable slope delta (CVSD) modulation/demodulation method. With digital voice encoding, the audio signal can be placed into the pulse code modulation (PCM) data stream. Some methods of digitizing voice can require a large amount of bandwidth. Using the CVSD method, an acceptable quality of audio signal is obtained with a minimum of bandwidth. Presently, there is a CVSD microchip commercially available; however, this paper will describe the design of a circuit based on individual components that apply the CVSD method. With the advances in data acquisition technology, increased bit rates, and introduction of a corresponding MIL-STD, CVSD modulated voice will become more utilized in the flight test programs and a good knowledge of CVSD will become increasingly important. This paper will present CVSD theory, supported by graphical investigations of a working circuit under different conditions. Finally, several subjects for further study into CVSD will be addressed.

För ett framgångsrikt varumärke är det viktigt att konsumenterna ser på företaget på samma sätt som företaget ser på sig själv. Det vill säga att ett företags identitet stämmer överens med företagets image. Om identitet och image faller långt ifrån varandra kan problem uppstå för företaget och det blir svårare att reparera sin image (Kapferer, 2005). När en ny juicebar intog den svenska marknaden med ett annorlunda koncept som alkoholfri cocktailbar ställdes identitet och image mot varandra. Med hjälp av Stuart Halls teori om encoding/decoding, Kapferers Brand Identity Prism och associationsteorier undersöktes Juiceverkets image och identitet. Det visade sig att det existerar ett gap mellan dem. Vissa delar av identiteten stämde överens med mottagarnas image av företaget, medan andra delar inte gjorde det. Ett gap existerar mellan mottagarnas image av företaget som fokus på hälsa, medan företaget menar att de inte är ett hälsoföretag. Mottagarna tolkar också företaget som trendigt och modernt medan Juiceverket menar att de undviker att följa trender. Kanske den största skillnaden i gapet mellan Juiceverkets identitet och image står i företagets identifiering av sig själva som en alkoholfri cocktailbar, medan mottagarna beskriver företaget som en trendig juicebar med hälsofokus.

Social media play a significant role in people’s daily communication and life. Even companies use them to reach a broader audience. This study aims to explore if Snapchat can be a useful platform for companies in their strategic communication, especially regarding corporate branding. Snapchat is the fastest growing social media today and they use content in a completely different way than other major social medias. This paper will show how Arla Sweden is using Snapchat to communicate with a specific target group, create engagement and strengthen brand identity. The study focuses on how users understand Arla´s content and is divided into two parts, where two qualitative methods are used. The first part focuses on Arla´s use of Snapchat and is conducted by an interview with an expert from Arla´s social media department. The second one aims to understand the user experience and is collected through four focus group interviews. The study is based on theories about corporate branding and Stuart Hall´s theory of encoding/decoding. The result shows that the users are critical to companies using Snapchat. The users view Snapchat as a private medium for friends and are negative to companies using it as a marketing tool. However, the study shows a positive result regarding users’ first experience with Arla´s content. The conclusion is that Snapchat can be used for corporate branding as long as companies make sure that the content is interesting enough for the target group.

This essay is about the hate Ghostbusters (2016) has received. To find out why the film is hated, a reception study has been done. YouTube and IMDb are the two websites used in this study to collect the hate-comments and reviews. Ghostbusters (2016) is a remake of the original film with the same name from 1984, the original solely has men in the main roles. A big difference between the two films is that the remake contains women instead of men in the main roles. The trailer of Ghostbusters (2016) got many “downvotes” on YouTube and there after the hatred streamed in. Why is the film hated?The theories used in this study contains subjects of representation, attraction and fat studies. As a method Stuart Hall’s Encoding/decoding was used to analyze the reception of the film. This essay contains content which can be connected to cultural studies and feminism.

A paired-associate list of three-word stimuli and one-word responses comprised the first list of an A-B, A-Br paradigm. Each of the three words from the first-list three-word stimuli was singly re-paired with first-list responses to make up three of the second-list conditions. The fourth second-list condition used the first-list stimuli plus re-paired first-list responses. Results obtained were that: (a) nine of the sixteen subjects spontaneously shifted encoding cues from first to second lists, (b) evidence of significantly greater negative transfer occurred only in the A-B, A1 2 3-Br condition, and (c) although not attaining significance level, across all A -Br conditions there were more errors on second-list learning for those not shifting encoding cues from first to second list. For those who did shift, performance was only slightly lower than the A-B, C-B control condition. Neither the encoding variability nor the associative variability theory was entirely supported. A gestalt interpretation was suggested.

The coding and transmission of the massive datasets captured by Earth Observation (EO) satellites is a critical issue in current missions. The conventional approach is to use compression on board the satellite to reduce the size of the captured images. This strategy exploits spatial and/or spectral redundancy to achieve compression. Another type of redundancy found in such data is the temporal redundancy between images of the same area that are captured at different instants of time. This type of redundancy is commonly not exploited because the required data and computing power are not available on board the satellite. This paper introduces a coding scheme for EO satellites able to exploit this redundancy. Contrary to traditional approaches, the proposed scheme employs both the downlink and the uplink of the satellite. Its main insight is to compute and code the temporal redundancy on the ground and transmit it to the satellite via the uplink. The satellite then uses this information to compress more efficiently the captured image. Experimental results for Landsat 8 images indicate that the proposed dual link image coding scheme can achieve higher coding performance than traditional systems for both lossless and lossy regimes.

Para cada pixel e suas coordenadas, esse valor único é armazenado em um vetor que é usado na reconstrução da imagem sem que sua qualidade seja comprometida. O método proposto apresenta melhorias em relação a dois outros algoritmos propostos anteriormente, sendo que um deles já é uma melhoria do primeiro. O algoritmo apresentado neste trabalho difere dos outros dois algoritmos estudados na diminuição significativa do espaço necessário para armazenamento das imagens, na determinação de uma taxa de compressão exata e na redução do tempo de processamento de decodificação. Um outro avanço apresentado foi a compressão de imagens coloridas utilizando a ferramenta wavemenu em conjunto com o algoritmo que determina a taxa de compressão. / This work presents an encoding algorithm for compressed images that represents each pixel of an image and its coordinates by a single value. For each pixel and its coordinates, this unique value is stored in a vector that is used in the reconstruction of the image without its quality being compromised. The proposed method presents improvements in relation to two other algorithms previously proposed, one of which is already an improvement for the first one. The algorithm presented in this work differs from the other ones in the foollowing characteristcs: by the significant reduction of the space required for image storage, the determination of an exact compression rate and the reduction of the decoding processing time. Another advancement was the compression of colored images using the tool wavemenu in improvement with the algorithm that determines the compression ratio.

As consumer demand for higher quality video at lower bit-rate increases, so does the need for more sophisticated methods of compressing videos into manageable file sizes. This research attempts to address these concerns while still maintaining reasonable encoding times. Modern segmentation and grouping analysis are used with code vectorization techniques and other optimization paradigms to improve quality and performance within the next generation coding standard, High Efficiency Video Coding. This research saw on average a 50% decrease in run-time by the encoder with marginal decreases in perceived quality.

<p>I den här uppsatsen har vi studerat hur en film aktiverar människors sociala och kulturella positioner. Vi visade filmen <em>Crash </em>för åtta komvuxelever, vilket följdes av en kvalitativ intervju med dem. Eleverna fick svara på frågor om sin egen bakgrund, filmens budskap och rollfigurer, hur de uppfattade filmen och den föreslagna verkligheten i filmen, samt frågor kring sin egen framtid. Informanternas svar har hjälpt oss att synliggöra hur det görs över- och underordningar i filmen. Med hjälp av vår bakgrund och analytiska verktyg har vi interagerat med våra informanter och de har bidragit med perspektiv som vi aldrig hade kunnat se med tillämpning av enbart teorier. Något som blev framträdande var att de applicerade problematiken som den amerikansktillverkade filmen tar upp, på ett svenskt samhälle. Vi kom fram till att filmen som populärkulturellt medel hjälper till att reproducera gamla maktordningar och fördomar. Trots att detta inte var filmskaparens intention, blir det här till fördomar och stereotypa föreställningar om att det finns rasskillnader. Med den här studien har vi synliggjort att filmen medverkar till att reproducera maktordningar. Film och dess folkliga inflytande, skulle kunna bli ett redskap för nytänkande runt klass, kön och etnicitet med mera.</p>
