Performance Analysis of a Godot Game-Agnostic Streaming Tool

Axelsson, Sam, Eriksson, Filip January 2023 (has links)
Background. Streaming games is traditionally done with video and audio both for watching on websites like Twitch and YouTube or playing via cloud gaming services. Streaming with video and audio requires good internet speeds to be of satisfactory quality therefore compression algorithms are used. Compression algorithms decrease bandwidth usage but it also lowers the quality of the stream. An alternative would be to stream game states and user inputs to recreate the game state for the viewer, this would lower the bandwidth usage while not compromising the quality. Objectives. This thesis aims to explore and compare a generalized streaming tool for the Godot engine. Where game states and user inputs are sent between two game instances to synchronize the host game with the client game. The tool will then be compared to a video and audio streaming setup in terms of image quality, bandwidth, and processing power. Methods. A combination of state replication and client simulation has been implemented for a streaming tool for games. Bandwidth, image quality, and processing power metrics are gathered for seven games for streaming with state replication and client simulation. The performance metrics have also been gathered when streaming video and audio data. To validate the streaming tool, the seven games were visually compared between images from the host and client of the streaming tool. Results. Compared to streaming video and audio data there was shown to be an overhead for streaming game states and user inputs. This overhead causes multiple games to have significant performance issues in terms of processing power for the CPU. In terms of image quality and bandwidth, the generalized streaming tool performed better.  Conclusions. The results showed that there is a possibility for a generalized streaming tool for the Godot engine to be successfully implemented. The implementation of the Godot streaming tool didn't work perfectly for each tested game, but most games use less bandwidth and there's no quality loss regarding the image quality. However, the streaming tool requires better hardware than traditional video and audio streaming. / Bakgrund. Att strema spel är oftast gjord med ljud och bild på webbsidor som Twitch eller Youtube, det används också i cloud gaming. Att skicka ljud och bild via nätet kräver bra bandbredd, även när man minskar bandbredden genom existerande komprimerings algoritmer som påverkar kvalitén. Genom att skicka knapp-tryckningar och lägen av spelet, så kan spelläget återskapas hos tittaren och där med minska användning av bandbredden och kvalitén skulle inte bli påverkad. Syfte. Det här examensarbetet utforskar ett spel-agnostiskt streaming verktyg för Godot. Verktyget fungerar genom att skicka knapptryckningar och speldata från en host till en klient för att synkronisera klientens spel till att matcha hostens spel. Sen kommer data från verktyget och traditionell streaming samlas in för att jämföra skillnaden i bildkvalitet, bandbredd, och processanvändning. Metod. Ett spel-agnostisk streaming verktyg blev implementerade för Godot, som använder sig av state replication och client simulation för att synkronisera spel. Sen samlades data in genom att testa sju spel gjorda med Godot, både för verktyget och traditionell video och ljud streaming. Datan som samlades in innehåll bandbredddata, process användning, och bilddata, datan jämfördes och blev analyserad. Resultat. Jämförd med traditionell streaming så använder den spel-agnostiska streaming verktyget betydligt mindre bandbredd och hade bättre bildkvalitet. Medantraditionell streaming använde mindre process användning och differensen mellanspelen var väldigt liten jämfört med streaming verktyget. Slutsatser. Resultatet visade att det finns en chans för spel streaming med knapp-tryckningar och spellägen att vara ett vettigt alternativ för traditionell streaming. Verktyget är inte helt spel-agnostisk för alla spel gjorda i Godot men det använder mindre bandbredd för de flesta spelen och bildkvaliteten är bättre. Men verktyget kräver bättre hårdvara än vanlig streaming med ljud och bild.

Managed Query Processing within the SAP HANA Database Platform

May, Norman, Böhm, Alexander, Block, Meinolf, Lehner, Wolfgang 03 February 2023 (has links)
The SAP HANA database extends the scope of traditional database engines as it supports data models beyond regular tables, e.g. text, graphs or hierarchies. Moreover, SAP HANA also provides developers with a more fine-grained control to define their database application logic, e.g. exposing specific operators which are difficult to express in SQL. Finally, the SAP HANA database implements efficient communication to dedicated client applications using more effective communication mechanisms than available with standard interfaces like JDBC or ODBC. These features of the HANA database are complemented by the extended scripting engine–an application server for server-side JavaScript applications–that is tightly integrated into the query processing and application lifecycle management. As a result, the HANA platform offers more concise models and code for working with the HANA platform and provides superior runtime performance. This paper describes how these specific capabilities of the HANA platform can be consumed and gives a holistic overview of the HANA platform starting from query modeling, to the deployment, and efficient execution. As a distinctive feature, the HANA platform integrates most steps of the application lifecycle, and thus makes sure that all relevant artifacts stay consistent whenever they are modified. The HANA platform also covers transport facilities to deploy and undeploy applications in a complex system landscape.

Client-server based statistical computing

Lehmann, Heiko 18 May 2004 (has links)
Viele statistische Problemstellungen erfordern in der heutigen Zeit den Einsatz von Computern. Der von uns in dieser Dissertation vorgestellte Ansatz kombiniert die Fähigkeiten der statistischen Softwareumgebung XploRe, mit den Vorteilen einer verteilten Client/Server Anwendung und den Möglichkeiten, die sich durch das Internet eröffnen. Um den Client einer großen Gruppe von Anwendern zugänglich zu machen, wurde Java zu seiner Realisierung verwendet. Das Ergebnis ist ein Statistikpaket, nutzbar via World Wide Web, das wie ein herkömmliches statistisches Softwarepaket verwendet werden kann, ohne die Notwendigkeit, das gesamte Softwarepaket zu installieren. Die vorliegende Arbeit gibt einen Überblick über die notwendige Softwareumgebung und erläutert die generelle Struktur der XploRe Quantlet Client/Server Architektur. Die Arbeit zeigt außerdem Anwendungen, in die diese Architektur bereits integriert wurde. / In today’s world, many statistical questions require the use of computational assistance. Our approach, presented in this thesis, combines the possibilities of a powerful statistical software environment, with the advantages of distributed client/server applications, and the opportunities offered by the Internet. In order to offer the client access to a large community, the Java language is used to implement the client’s functionalities. The result is a statistical package - usable via the World Wide Web - that can be used like a traditional statistical software package, but without the need for installing the entire software package on the user’s computer. This thesis provides an overview of the desired software environment, and illustrates the general structure with the implementation of the XploRe Quantlet Client/Server architecture. It also shows applications, in which this architecture has already been integrated.

You've got mail the study of the attorney-client privilege and the use of electronic mail

McConnell, Justin W. 01 May 2011 (has links)
The prolific use of the internet and electronic mail within the legal profession presents novel challenges to the application of the attorney-client privilege; especially, in regards to protecting intended confidential communications relayed through e-mail. This thesis addresses the question of whether an attorney in Florida, through electronic mail use, can waive his client's right to the protections of the attorney-client privilege. After a review of current case law, law review articles, statutes, and texts, this thesis concluded that an attorney's communication through e-mail warrants a reasonable expectation of privacy, permitting the attorney to speak in reasonable confidence to clients through the web. However, attorneys, ethically, should consider the strong repercussions for using such a potentially transparent medium for communication. By examining the relationship between current law, the application of the attorney-client privilege, and a reasonable expectation of privacy, this study provides a comprehensive analysis for attorneys concerned with electronic mail usage. Lastly, this thesis provides attorneys with best practices for their electronic mail communications.

Vilka företag anlitar en revisor med en disciplinär åtgärd? : En jämförelse mellan sanktionerade och icke-sanktionerade revisorer

Ellman, Ebba, Hansson, Sofia January 2024 (has links)
Revision är en systematisk process som innefattar en systematisk insamling av bevis för attslutligen lämna ett yttrande om ett klientföretags redovisning. Syftet med revision är attundersöka och utvärdera relevans och validitet i klientföretagets finansiella antaganden (Eilifsen et al, 2014, s. 12). Revision anses vara viktigt för klientföretaget och dess aktieägare,likaväl som för intressenter och andra utomstående parter (Eilifsen et al., 2014, s. 5). Revisorer och deras arbete är i sin helhet styrda av flertalet lagar och förordningar, där överträdelser eller åsidosatta skyldigheter kan leda till en sanktion. I denna studie har vi valt att fokusera på tillsynsärenden och revisorer som fått en sanktion utfärdad mot sig. I Sverige finns det en specifik myndighet som ansvarar för tillsynen av revisorer och som därmed även utreder disciplinära ärenden. Den myndigheten heter Revisorsinspektionen och ansvarar främst för tillsyn av revisorer och revisionsbolag men även för examination samt auktorisation av revisorer (Revisorsinspektionen, u.å. d). Revisorsinspektionens tillsynsmyndighet är myndighetens största verksamhetsområde. Förekommande ärendebeslut vid disciplinära ärenden hos Revisorsinspektionen är varning, erinran samt upphävande, vilka är de ärendebeslut som vi i denna studie benämner som sanktioner. Även ärendebeslut så som ingen åtgärd, avskrivning samt beslut i annat ärende är förekommande hos myndighetens tillsynsverksamhet men leder inte till någon sanktion.Denna studie syftar till att bidra med kunskap avseende disciplinära åtgärder mot revisorer med fokus på klientföretagen. Studien syftar även till att identifiera eventuella kännetecken hos de klientföretag som väljer att anlita en sanktionerad revisor och ifall dessa kännetecken skiljer sig från eventuella kännetecken hos företag som anlitar icke-sanktionerade revisorer. Studien bygger på studier av två olika tidsperioder som syftar till att kunna jämföra och dra slutsatser om dessa kännetecken förändras över tid. Denna studie har sin grund i tidigare forskning som utförts inom revision men även företagsekonomi. Denna studie har även ett tydligt fokus på valet av revisor där revisorn fått en disciplinär åtgärd – därmed sanktionerade revisorer ur ett klientföretagarperspektiv. Detta är något som differentierar denna studie från tidigare studier och därmed är ett givande teoretiskt bidrag. Den tidigare forskning som funnits i samband med litteratursökning, har ett större fokus på valet av revisor i form av auditor choice. Däremot återfinns inga tidigare studier med ett fokus på sanktionerade revisorer i relation till auditor choice. Vilket gör denna studie till den första studien som sammankopplar dessa områden i samma studie. Utifrån denna studie har vi kunnat dra slutsatsen att både kön på VD och styrelse har en inverkan på valet av sanktionerad revisor. En ytterligare slutsats som kunnat dras av denna studie är att tiden sedan utfärdad sanktion har en påverkan på de avgörande kännetecknen hos klientföretagen vid val av sanktionerad revisor.

Clavardage en contexte de service à la clientèle : des pratiques rédactionnelles en émergence?

Thiffault-Roux, Roxanne 06 November 2023 (has links)
Titre de l'écran-titre (visionné le 31 octobre 2023) / Nous observons depuis quelques années un changement important dans le choix du canal de communication de nombreux consommateurs : ils choisissent plus fréquemment d'utiliser le clavardage plutôt que la téléphonie pour contacter une organisation. Ce changement d'habitude demande aux organisations de s'adapter, car les clients ont des attentes élevées en termes de vitesse de réponse et de personnalisation des messages. Comment ont-elles organisé leurs structures internes? Ont-elles bonifié les équipes en place ou ont-elles mis sur pied des équipes dédiées à ce nouveau service? Qui composent ces équipes de travail? Pour répondre à ces questions, nous avons d'abord cherché connaître le profil les rédacteurs et à comprendre leur environnement de travail puis à dégager des pratiques professionnelles liées au clavardage. Ensuite, nous nous sommes penchée sur la chaîne éditoriale du clavardage et avons établi sa relation avec l'écosystème du service à la clientèle. La méthodologie utilisée est de nature qualitative, basée sur des entretiens avec 10 répondants. Elle a été effectuée en deux étapes. Dans la première, nous avons fait parvenir un questionnaire en ligne aux participants et, dans la seconde, nous avons réalisé une entrevue semi-dirigée d'environ 60 minutes. Le questionnaire avait pour but de collecter les données sociodémographiques des 10 répondants et de personnaliser les questions de l'entrevue semi-dirigée. Les données recueillies ont été compilées dans une grille d'analyse qui nous a permis de voir émerger certaines tendances. Les résultats de cette recherche montrent que le clavardage est généralement géré par les équipes du service à la clientèle, qui sont composées de clavardeurs aux profils variés en termes de diplôme et d'expérience de travail. Ceux employés dans de petites organisations (moins de 250 employés) doivent cependant être polyvalents et débrouillards, car ils sont responsables de nombreuses tâches (gestion de l'infolettre, rédaction de documents divers, édition de site web, etc.) et ils sont parfois seuls dans leur équipe. Cette recherche schématise les relations entre le client et les clavardeurs, ainsi que les processus internes des organisations nécessaires à la réussite de la tâche, soit celle de répondre aux requêtes des clients le plus rapidement possible. / Over the past few years, we have observed a significant change in the communication channel choice of many consumers : they rather use the chat than the phone to contact organizations. This change of habit requires organizations to adapt, as customers have high expectations in terms of response speed and personalization of messages. How did they organized their internal structures? Did they improved the teams in place, or did they set up teams dedicated to this new service? Who made up these work teams? To answer these questions, we first sought who the editors were and how their work environment was, to then identify professional practices related to chat. Next, we looked at their chat editorial chain and established its relationship to the customer service ecosystem. The methodology used here is qualitative as it is based on interviews with 10 respondents. It was carried out in two stages. In the first stage, we sent an online questionnaire to the participants and, in the second one, we conducted a semi-directed interview of about 60 minutes with them. The purpose of the questionnaire was to collect socio-demographic data from the 10 respondents and to personalize the questions of the semi-structured interview. The data collected was compiled into an analysis grid that allowed us to see some trends emerge. The results of this research show that chat is generally handled by customer service teams, which are made up of chat users with varying backgrounds in terms of education and work experience. Those employed in small organizations (fewer than 250 employees), however, must be versatile and resourceful, as they are responsible for many tasks (newsletter management, writing various documents, website editing, etc.) and they sometimes work alone. Altogether, this research schematizes the relationships between the customer and the chat users, as well as the internal processes of the organizations necessary for the success of the task, namely that of responding to customer requests as fast as possible.

Förtroende och makt i socialt arbete : En studie om socialsekreterares upplevelser / Trust and power in social work : A study on social workers experiences

Bengtsson, Ida, Niklasson, Therese January 2015 (has links)
The purpose of this study is to, from a perspective of power, understand and interpret Swedish social workers experiences and comprehension of their clients trust in them. The study is based on interviews with eight social workers from two municipalities in the south of Sweden. Five themes were identified that represents the five different forms of power which the social workers used on a daily basis. The themes were: normalization, demands and control, the social worker as an expert, the conflict between bio power and disciplinary power and the transparency of power. The analyzis of this study is based on the comprehension of hermeneutics as well as previous research on trust and power in client relationships. As a conclusion we found that whether the interviewees stated that their work was about the exercise of power or not, we could still identify that all of them used some form of power on a daily basis. We also saw that trust was not always the essential part of a working client relationship. Through this study, and by using the theory of power by Michel Foucault, we found that power therefore is something that exists in all relationships whether you believe you exercise it or not.

Portable TCP/IP server design

Jolliffe, Robert Mark 25 August 2009 (has links)
There are a number of known architectural patterns for TCP/IP server design. I present a survey of design choices based on some of the most common of these patterns. I have demonstrated, with working code samples, that most of these architectural patterns are readily portable between UNIX and Windows NT platforms without necessarily incurring significant performance penalties. / Computing / M.

RANGE SAFETY CASE STUDY: WESTERN RANGE CENTRALIZED TELEMETRY PROCESSING SYSTEM (WR CTPS), A LARGE DISTRIBUTED GROUND SYSTEM

Mather, Jonathan, Shaw, Nancy 10 1900 (has links)
ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / This paper presents a case study of the Western Range Centralized Telemetry Processing Subsystem (WR CTPS). This system was developed by Lockheed Martin Integrated Systems and Global Services and L-3 Communications Telemetry-West as part of the Range Standardization and Automation (RSA) IIA program. Requirements included real-time simultaneous acquisition of 16 PCM streams at rates of up to 30M bits per second; real-time processing; and data display on workstations connected over a gigabit Ethernet network. This system is designed for range safety and needs to be fault-tolerant while maintaining 100 percent data availability in the event of a single failure during an operation. The development of such a system demanded a rigorous Systems Engineering approach to ensure the successful upgrade and deployment onto the range infrastructure. This case study provides an overview of the system technical requirements and its architecture. The summary presents challenges encountered during the development and lessons learned while meeting them.
