Cleanbox - Flashbaserad Produktpresentation
Cleanboxen som den kallas är en flashbaserad2 produktpresentation.
Simply Quality är ett företag som gör analyser och mäter renhet hos olika
föremål på partikelnivå.
Ett exempel på detta kan vara att ett företag som tillverkar bildelar skickar
en del efter produktion för att få en analys på hur mycket partiklar/smuts som
sitter kvar efter tillverkning.
Vårt arbete var att ta fram en produktpresentation för deras mobila labb som
säljs till företag som vill kunna göra sina analyser på plats. Behovet var att
på något sätt kunna presentera Cleanboxen visuellt för sina kunder..
Peer-to-peer som företagslösning
Problemområde:
Idag är användandet av peer-to-peer (P2P) - applikationer såsom KaZaa, ICQ och
Seti@home utbrett bland privatpersoner. Användningen inom företag är dock ännu
i sin linda.
Vi kommer därför i den här uppsatsen utreda om ett eventuellt införande av P2P-
teknik i ett företagsnätverk ger några fördelar jämfört med en klassisk
Client/Server-lösning.
Hypotes:
Arbetet bygger på hypotesen: ?En P2P-lösning ger fördelar för företaget
jämfört med en Client/Server-lösning?
Genomförande:
För jämförelsen mellan P2P och Client/Server definierades och jämfördes fem
områden: Säkerhet, Användbarhet, Tillgänglighet, Bandbredd samt
Utrustningskrav.
Slutsats:
Inom områdena Användbarhet och Tillgänglighet ger en P2P-lösning klara
fördelar, däremot inom områdena Säkerhet och Bandbredd visar Client/Server-
lösningen istället klara fördelar. Området Utrustningskrav är oavgjort då det
inte
finns någon märkbar skillnad på lösningarna.
Säkerhetsproblemen är P2P-teknologins akilleshäl och det problem som är mest
troligt att stoppa stora investeringar i framtiden om det inte löses.
Slutsatsen av vår jämförelse blir sålunda:
För ett företag som redan har ett existerande Client/Server-nätverk är det inte
någon idé att helt byta system, däremot kan det vara av intresse att
introducera en applikation som möjliggör skapandet av så kallade Virtuella
Nätverk.
För ett helt nytt företag kan skapandet av ett P2P-nätverk vara ett väl så
intressant alternativ till Client/Server.
XML som informationsbärare för EDI
Information handling has been a key issue for different companies for a long
time. Electronic Data Interchange (EDI) is used to transfer different business
documents from one company to another. This is done in such way that the
information itself is separated from how this information is stored and handled
in the companies internal systems. As different companies have different
systems there is a need for a standardised format for this exchange.
There is a big difference between EDI-systems based on what kind of
EDI-standard is used. The most common standard in Europe is EDIFACT, but with
increased interest of using the Internet for business communication there is a
need for a standard that is adjusted for use over the Internet.
Chinese Remainder Theorem
Chinese Remainder Theorem is used to solving problems in computing, coding and cryptography. In computing we can compute with shorter numbers instead of large numbers and this will make the computing-process faster and easier. In coding it can be used for error-searching and error-regulating.Cryptography means that we can send a coded message and that no one will be able to read it without the decode-key which is based on prim-numbers. I am writing about the history of mathematics and how the number- and decimal number-system is used in Babylon, Egypt, Greece and in China. Abacus was a very important aid to calculate advanced mathematical problems.
Analytisk mekanik med datoralgebra
In this project we have used the theory of analytical mechanics to derive equations of motion for complex mechanical systems in order to study their behaviour over time. Even if the theory provides powerful tools to tackle tough problems which would be very hard to solve by methods of Newtonian mechanics, you are still relatively limited without running any computer simulations. One realises that in a faster rate it will be an incredibly difficult task to find an analytical solution when the degrees of freedom increases. Even if one would succeed to derive the equations, one still has to solve them to get the information of the systems behavior. Of experience one knows that the equations in general are nonlinear and hence must be integrated numericaly.
Revisionsplikten : Förändringen av revisorernas yrkesutövning sedan revisionsplikten avskaffades
The thesis is based on a case study of a Swedish discussion forum where survivalism and prepping is the main focus. The awareness of an abrupt and immanent breakdown together with a full and thorough preparation for any conceivable threat posed by that breakdown is what legitimizes survivalism and prepping. This preparation, or risk-proofing is 1) grounded in an isolation of the body and its predispositions from perceived risks, and 2) actualized through artefacts, theoretical and practical knowledge and awareness. Stories of the embodied survivalist are also stories of masculine and heterosexual subjects and ?the others?.
Mellan medborgare och myndigheter. Arbetsförmedlarens roll i kontexten av jobbgarantin för ungdomar.
Current technology offers many possibilities for remotecommunication. Nevertheless, people with cognitive and communicativedisabilities have limited access to common communication technology like textmessaging via a mobile phone. This study is part of the project Text messagingwith picture symbols - a possibility for AAC users and people with cognitiveimpairments. Semi structured interviews were used to investigate three menand four women?s experiences of using Windows mobiles with adaptedfunctions for text messaging.
Private Equity-bolags styrning av portföljbolag; En fallstudie av värderingsmodellens översättning till olika organisationsnivåer.
The aim of this thesis is to investigate how a valuation model of a Private Equity firm is interpreted into a management control system within the company's different organizational levels. A case study was developed based on the infra-net company Eltel. The management control systems developed by Malmi and Brown (2008)(1) was used to characterize the control systems at each organizational level. The building blocks of this system are planning, cybernetic, reward/compensation, administrative and culture. Miller and O'Learys (2007)(2) theory of mediating instruments and technology roadmaps was applied to analyze the mediating process of the valuation model.
Studenters mobilanvändning under föreläsningar : En studie om hur studenters koncentrationsförmåga påverkas av mobilanvändning under föreläsningar
In Sweden there is a long ongoing discussion about computer and cellphone usage during lectures in school. The discussion has mainly covered elementary school up to college students, but this topic is at least as relevant for university students. Today cellphones are so advanced; you can do everything with one that you previously only could do with a computer, the difference is that everyone is carrying one with them all the time. This study shows how concentration during lectures is affected by the cellphone accessibility and usage. With this study we want to find out how university students perceive cellphone usage affects their own concentration during lectures.

Cyborglandskap : landskapet, människan och teknologin
By using the cyborg as a structural tool to analyze certain aspects of human interaction with what can be perceived as landscape or landscape architectural elements, this thesis seeks to explore the concept of the cyborg landscape in order to place human practice in the context of postmodern ideas of the end of true nature. Ever since human kind has externalized evo-lution by using tools and extending the body with technological inventions, we have also taken our surroundings out of their natural trajectory. Everything we do that is conditioned by the use of technology is altering that which we perceive as nature and natural. Since we have been doing this for millennia we have of course also altered our surroundings by the influence of technology.This thesis uses three examples of landscape or landscape architectural elements that are conditioned by the integration of technology to explore this practice through a postmodern model of analysis based on the concept and basic premises of the cyborg, or the cybernetic organism. A cybernetic organism is in short an organism that has functioning technological parts integrated into its system.
Den Moderna Webben: Kan HTML5 konkurrera med traditionell programvara?
Vi ser en förändring i hur vi använder applikationer. Från att tidigare varit
associerat till en dator och begränsat till ett par operativsystem finns de
numera överallt. Fler plattformar innebär att man måste utveckla en applikation
till var och en av dessa. Detta gör att utvecklingstiden och kostnaderna ökar
och efterfrågan av crossplattformlösningar i form av webbapplikationer har
därför ökat.
Vi tittar närmare på hur det går att använda sig av HTML5, och övriga tekniker
som en modern webbläsare har integrerat stöd för, för att utveckla webbaserade
applikationer. Vi tar reda på om det finns några hinder eller begränsningar i
detta och om det finns några fördelar i att använda webben som plattform.
Resultatet indikerar att med de nya tekniker som är på ingång kan man utveckla
webbbaserade applikationer med prestanda motsvarande Java eller C#.
Att designa användargränssnitt för äldre människor med afasi
Our aim in this work has been to redesign ModernFamilies and make a user-friendly interface for people with aphasia. The focus has been to identify general issues they might face while using different technology and applications, in order to find better alternative design for ModernFamilies, with a focus on usability. To approach this issue, we used a qualitative method. Our study includes several interviews and observations preformed in conjunction with the AGNES project (AGeing in a NEtworked Society) and speech therapists. Aphasia requires simple design that in the same time gives them support to understand and use technology and different applications.
Analys av off-design prestanda för ett absorptionskylsystem
This master thesis project at KTH is performed in the Mechanical and Aerospace Engineeringdepartment at University of Florida (UF). The thesis is a small part of a gas turbine researchproject where a vapour absorption refrigeration system (VARS) and a high pressure regenerativeturbine engine (HPRTE) are integrated together. The main objective is to build a computermodel of the VARS. The computer model is supposed to be used to analyse the off-designperformance of the VARS and should also be easy to integrate as a subroutine in a more complexsystem model. To model the VARS some knowledge of the absorbent/refrigerant mixture had tobe well known, in this case a mixture of ammonia and water.
ZigBee-teknikens möjligheter att trådlöst överföra EKG-signaler
In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power.
