Svenska organisationers utnyttjande av ny teknik : En studie om svenska kommuners IT-avdelningars syn på ny teknik och deras faktiska handhavande

Rikardsson, Douglas, Källqvist, Erik January 2015 (has links)
Stora organisationer anses ofta vara trångsynta vad gäller sin syn på ny teknik och sitt nya sätt att arbeta. De måste ofta genomgå många processer innan beslut kan tas och förändringar kan ske. Om så skulle vara fallet uppstår ett problem i form av att organisationerna inte följer med utvecklingen och därigenom blir kontraproduktiva. Skulle dessa teorier stämma för exempelvis svenska kommuners IT-avdelningar upplyses ett problem som i längden kan drabba oss själva, det vill säga Sveriges medborgare. För att kunna belysa problemet har denna studie använt sig av Windowsverktyget PowerShell för att få ett mätverktyg som kan påvisa om IT-avdelningar är restriktiva mot förändringar inom tekniska områden. Med hjälp av en enkätundersökning kunde vi frambringa kvantitativ data som i sin tur kunde visa att det tidigare nämnda problemet påträffas. Slutsatsen är att kommunerna själva tycker att de har en positiv syn på ny teknik och nya arbetssätt men att deras handlingar bevisar annat.

Li, Jie, Lu, Yuting January 2010 (has links)
<p>Abstract:The kernel system of Windows is more thoroughly exposed to people. So, thekernel-level Rootkits techniques are now laid on greater emphasis. It is very importantto maintain the security of computers and to conduct an in-depth research on theoperational mechanism by using kernel-level Rootkits in hiding its traces. Since theinvolved core techniques are beginning to catch on nowadays, we should analyzesome new key techniques employed for application of Rootkits, discuss the specificmethods and propose a set of defense strategy for computer security.</p>

Modelling and Optimization of an Airflow Window with Between-the-Panes Shading Device

Hadlock, Chris January 2006 (has links)
Abstract <br /> This thesis deals with the numerical investigation of the upper section of a building-integrated photovoltaic/thermal double-fa??ade. The upper section consists of an airflow window with a between-the-panes roller blind. The purpose of this thesis is to develop and validate a numerical model in order to optimize the design of the system. The lower section, which consists of building-integrated photovoltaics, has already been modelled at Concordia University. The results from the lower section will be used as inputs to the upper section. <br /><br /> The validation of the model was carried out in three stages. In the first stage, the model was validated for forced convection between parallel plates using analytical data as benchmarks. In the second stage, a radiation analysis was performed for single, double and triple-glazed closed system with natural convection only. In the third and final validation stage, experimental data gathered from the Solar Lab at Concordia University was compared to the numerical model. The model included the effects of radiation for an open system with forced convection and a between-the-panes roller blind. For all three stages of validation, the results from the model were in excellent agreement with the benchmarking data. <br /><br /> Once the model was validated, a parametric analysis was used to determine the effects of varying key model parameters. The outlet temperature, the useful energy gain, and the net energy gain of the system were plotted as a function of inlet velocity. It was concluded that as the flow rate through the cavity was increased, the air temperature at the outlet approached that of the outdoor ambient air. By computing the heat generated from advection as well as the total losses from the system, including the heat lost from the indoor environment as well as the power consumed by the fan, the net useful heat gain of the system was calculated as a function of insolation level. Operating points (of the fan) for the upper section were therefore determined as functions of insolation level. A second order polynomial equation provided an excellent fit to the data and could therefore be used to determine the ideal operating point of the upper section for any insolation level.

Deposition and characterisation of nickel oxide based coatings for advanced glazing applications

McMeeking, Graham Donald January 1997 (has links)
This thesis is a comparative study of nickel oxide based thin films for use as a counter electrode in a variable transmittance electrochromic device. Coatings have been prepared using anodic electrodeposition, colloidal precipitation and radio frequency (r.f.) sputtering. Systematic studies of the effect of deposition process parameters on optical and electrochromic properties of such films have been undertaken. Optimum conditions for the deposition of coatings deposited by colloidal and anodic deposition have been determined. A novel process for the colloidal deposition of electrochromic a-Ni(OH)2 coatings using a simple one dip process is reported. Also the electrochromic properties of coatings anodically deposited from aqueous solutions containing NiS04 and NH40H were improved by the addition of the non-ionic surfactant polyoxyethylene sorbitan monolaurate. Spectroscopic and electrochemical analytical techniques were used to identify the chemical composition of the coloured and bleached states. It was found using Fourier transform infra-red spectrophotometry (FTIR) that coatings deposited by anodic and colloidal deposition contained f3-Ni(OH)2 and a-Ni(OH)2 respectively in the as-deposited and transparent states. For coatings deposited by both techniques 13 or y-NiOOH was detected in the coloured state using FTIR. Using Raman spectroscopy, y-NiOOH was detected in the coloured state for coatings deposited by anodic deposition from solutions containing the additive polyoxyethylene sorbitan monolaurate. I3-Ni(OH)2 was also detected in the transparent state of r.f. sputtered coatings that were electrochemically cycled in 1M KOH(aq). Using cyclic voltammetry the oxidation of nickel hydroxide to the oxyhydroxide was detected during colouration for coatings produced using anodic electrodeposition, colloidal precipitation and r.f. sputtering (after cycling sputtered films for 1 hour in 1M KOH(aq)). This information has been compared for films prepared using the different deposition techniques to enable the respective colouration mechanisms to be elucidated. Prototype electrochromic devices have been constructed and their performances assessed. It can be concluded that nickel oxide based coatings can be used as suitable counter electrodes for hydrated electrochromic devices.

Analysis of Windows 8 Registry Artifacts

Stormo, Jeremy M 20 December 2013 (has links)
Microsoft’s series of Windows operating systems represents some of the most commonly encountered technologies in the field of digital forensics. It is then fair to say that Microsoft’s design decisions greatly affect forensic efforts. Because of this, it is exceptionally important for the forensics community to keep abreast of new developments in the Windows product line. With each new release, the Windows operating system may present investigators with significant new artifacts to explore. Described by some as the heart of the Windows operating system, the Windows registry has been proven to contain many of these forensically interesting artifacts. Given the weight of Microsoft’s influence on digital forensics and the role of the registry within Windows operating systems, this thesis delves into the Windows 8 registry in the hopes of developing new Windows forensics utilities.

Urban Food Growth: Designing for Vertical Building Surfaces

Wilson, Allison, Wilson, Allison January 2012 (has links)
This thesis attempts to determine if food-producing plant growth can be incorporated within a building envelope to create an ideal plant growth environment while simultaneously enhancing the thermal properties of the building envelope. A window system was designed as a means of bringing food production into the built environment in an easily accessible fashion from the interior of a high-rise apartment complex. The Ya-Po-Ah Terrace in Eugene, Oregon, was chosen as a case study site for research on how a window could promote health, provide nutrition, and enhance the thermal comfort of the inhabitants. The design of the window unit is founded in precedent research on methods of plant growth in urban environments and systems for growing food in small and efficient ways. The design found that it is possible to create an ideal plant growth environment within a building assembly for use as a food production method for building inhabitants.
