Full textEDI står för elektroniskt utbyte av data från dator till dator och sker mellan kända affärspartners. När EDI införs i en relation mellan två organisationer anses relationen bli mer komplex än tidigare. Syftet med detta arbete är därför att undersöka hur EDI påverkar interorganisatoriska relationer.
Undersökningen utförs genom att studera affärsrelationerna mellan en offentlig förvaltning och tre av dess leverantörer. I dessa relationer studeras speciellt hur förhandlingsstyrkan, flexibiliteten och tillförlitligheten har påverkats av att EDI har börjat användas för den offentliga förvaltningens inköpsprocess.
De slutsatser som dras är att de undersökta faktorerna förändras i takt med att EDI blir alltmer integrerat i affärsrelationerna. Initialt byggs vissa omställningskostnader upp, som ökar leverantörernas förhandlingsstyrka. När EDI-kommunikationen fungerar kan kunden komma att öka sin förhandlingsstyrka på grund av bättre informationsdelning och något större inköpsvolymer hos leverantören. Flexibiliteten har ännu inte förändrats nämnvärt, medan tillförlitligheten i leveranserna har ökat till följd av EDI.

Full textThis thesis investigates ion energy distributions (IEDs) during plasma immersion ion implantation (PIII). PIII is a surface modification technique where an object is placed in a plasma and pulse biased with large negative voltages. The energy distribution of implanted ions is important in determining the extent of surface modifications. IED measurements were made during PIII using a pulse biased retarding field energy analyser (RFEA) in a capacitive RF plasma. Experimental results were compared with those obtained from a two dimensional numerical simulation to help explain the origins of features in the IEDs. Time resolved IED measurements were made during PIII of metal and insulator materials and investigated the effects of the use of a metal mesh over the surface and the effects of insulator surface charging. When the pulse was applied to the RFEA, the ion flux rapidly increased above the pulse-off value and then slowly decreased during the pulse. The ion density during the pulse decreased below values measured when no pulse was applied to the RFEA. This indicates that the depletion of ions by the pulsed RFEA is greater than the generation of ions in the plasma. IEDs measured during pulse biasing showed a peak close to the maximum sheath potential energy and a spread of ions with energies between zero and the maximum ion energy. Simulations showed that the peak is produced by ions from the sheath edge directly above the RFEA inlet and that the spread of ions is produced by ions which collide in the sheath and/or arrive at the RFEA with trajectories not perpendicular to the RFEA front surface. The RFEA discriminates ions based only on the component of their velocity perpendicular to the RFEA front surface. To minimise the effects of surface charging during PIII of an insulator, a metal mesh can be placed over the insulator and pulse biased together with the object. Measurements were made with metal mesh cylinders fixed to the metal RFEA front surface. The use of a mesh gave a larger ion flux compared to the use of no mesh. The larger ion flux is attributed to the larger plasma-sheath surface area around the mesh. The measured IEDs showed a low, medium and high energy peak. Simulation results show that the high energy peak is produced by ions from the sheath above the mesh top. The low energy peak is produced by ions trapped by the space charge potential hump which forms inside the mesh. The medium energy peak is produced by ions from the sheath above the mesh corners. Simulations showed that the IED is dependent on measurement position under the mesh. To investigate the effects of insulator surface charging during PIII, IED measurements were made through an orifice cut into a Mylar insulator on the RFEA front surface. With no mesh, during the pulse, an increasing number of lower energy ions were measured. Simulation results show that this is due to the increase in the curvature of the sheath over the orifice region as the insulator potential increases due to surface charging. The surface charging observed at the insulator would reduce the average energy of ions implanted into the insulator during the pulse. Compared to the case with no mesh, the use of a mesh increases the total ion flux and the ion flux during the early stages of the pulse but does not eliminate surface charging. During the pulse, compared to the no mesh case, a larger number of lower energy ions are measured. Simulation results show that this is caused by the potential in the mesh region which affects the trajectories of ions from the sheaths above the mesh top and corners and results in more ions being measured with trajectories less than ninety degrees to the RFEA front surface.

Full textDen fenomenala tillväxten av IoT och populariteten hos mobilstationerna har snabbt ökat efterfrågan på WLAN-nätverk (känd som IEEE 802.11 och WiFi). WLAN är ett billigt alternativ för mobilnätet och är ett olicensierat spektrum för att bygga huvudplanen för att bädda in Internet i allt-och-var som helst. Samtidigt är det inte trivialt att övervaka antalet IoT och WiFi-aktiverade enheter över bostäder och företag. Därför kräver framtida WiFi nätverksarkitektur ett smidigt hantering paradigm för att tillhandahålla internt stöd och säkerhet för WiFi-nätverk.Användningen av IoT och mobilanvändningsapplikationer är beroende av skalbarhet och högpresterande beräkningar av moln. Cloud computing har helt centraliserat den nuvarande datacenters nätverksarkitektur och det ger beräkningsintensiva, höghastighetsnätverk och realtidssvar påbegäran från IoT. IoT-till-moln kommunikationen är kärnan i nätverkssäkerhetshänsyn och de har ett allvarligt behov av ständig förbättring och säkerhetshärdning inom deras internätverk. Baserat på antalet undersökningar och analyser av genererad trafik av IoT har det observerats. Det finns det betydande antalet massiva spoofing-orienterade attacker som riktar sig mot molntjänster, lanseras från komprometterad IoT.På grundval av att granska tidigare undersökningar om IoTs mest genomförda nätverksattacker finns det en utmanande och gemensam egenskap som ofta utnyttjats i de många massiva internetattackerna. Detta arbete kommer att undersöka de befintliga lösningarna som har implementerats för att skydda både traditionella och mjukvariga nätverksparadigmer. Därefter föreslår det tillvägagångssättet för detta arbete som möjliggör IoT-värdnät skyddade genom att använda SDWN inom den föreslagna modellen för att mildra poofing-orienterade nätverksattacker. Dessutom erbjuder den föreslagna lösningen miljöhållbarhet genom att spara strömförbrukning i nätverksenheter under nätverksdrift. Den praktiska förbättringen av den föreslagna modellen mäts och utvärderas inom den omgivande miljön av Mininet-WiFi.

Rural Indian farmers lack an available, affordable, usable, and actionable means to diagnose soil health, which is a prerequisite for judicious application of fertilizer. Although government labs and mobile kits are available, these fail to meet the aforementioned qualities; as a result fewer than 5% of rural Indian farmers have ever performed a soil test. This thesis details the design and characterization of a point-of- use soil testing device, comprising a set of disposable ion-selective electrode (ISE) strips and a handheld electrochemical reader, which together transduce soil analyte concentrations into a numeric input for a mobile-phone based fertilizer recommendation engine. As a proof-of-concept, potassium (K+) selective electrodes are studied, because K+ is essential to plant growth and reproduction. The strips employ a simple two electrode system, wherein carbon nanotube and silver chloride inks are the electrode contacts, plasticizer-free butyl acrylate ion selective membranes are located on the working electrodes, and sodium-chloride doped polyvinyl butyral membranes provide stable reference potentials. The electrodes were fabricated by a combined screen printing and drop casting process, and the protocol, extraction solution, and reference potential stability were tuned to maximize ISE performance and repeatability. Using a mathematical model and supporting experiments, we verified that hydrogen selectivity determines the detection limit, and furthermore, that scientists can tune the ionophore-ionic site ratio to minimize this effect. Using the final electrode fabrication process, a set of 20 full ISE devices in the presence of 0.02M SrCl2 extraction solution were shown to have sub-uM detection limits and near-Nernstian average sensitivity (61 mV/decade). When compared to ICP data for a set of 30 soil samples using the final reader, the sensors demonstrated a 0.898 correlation factor. Workshops in India were conducted to determine user needs and corresponding product attributes, as well as a "usability index" for the system assessed across farmer demographics. The favorable system performance proves that solid-state ISEs are a promising technology for soil diagnostics in resource-constrained environments.

Ionic liquid ion sources (ILIS) are devices capable of producing positive and negative molecular ion beams through field evaporation from room-temperature molten salts. If sufficiently high hydraulic impedance from the liquid-supporting emitter is provided such that the ratio of flow rate Q to liquid's electrical conductivity K is sufficiently small, a pure ionic regime (PIR) can be achieved, in contrast with traditional electrosprays that produce charged droplets, or mixtures of droplets and ions. The PIR provides high current density from a point source, making ionic liquid ion beams suitable for use in focused ion beam (FIB) applications. The use of ionic liquids in focused ion beams could allow the production of sub-100 nm beams of up to kiloDalton organic ions as well as reactive species, with the possibility of engineering ionic liquid properties for a specific application. In addition, using micro-fabricated and nano-structured emitter arrays operating in the PIR can give access to efficient and compact positive or negative ion sources, for applications from spacecraft thrusters to deep reactive ion etchers (DRIE). There is a need for novel tip geometries and materials that favor the stable formation of a single emission site on the liquid supporting structure, while providing a continuous liquid supply compatible with the PIR. In this thesis, porous carbon based on resorcinol-formaldehyde xerogels is introduced as an emitter substrate. The target pore sizes and emitter geometries to attain the PIR are obtained through analytical estimates. The carbon xerogel can be shaped to the required micron-sized geometry through mechanical polishing. Time-of-flight mass (TOF) spectrometry is used to verify that charged particle beams produced from the mechanically polished carbon xerogel source, infused with the ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate (EMI-BF₄), contain solvated ions exclusively. In the case of the liquid 1-ethyl-3-methylimidazolium bis(trifluorometrylsulfonyl)imide (EMI-Im), mixed ion-drop operation is obtained. Laser micro-machining has been validated as a manufacturing technique to shape carbon xerogel into emitters. This technique should allow the production of emitter arrays for DRIE or propulsion applications, and allow the reproducible fabrication of emitters for FIB. Stable emission has been obtained from a laser micromachined tip infused with the ionic liquid EMI-BF₄ . The results of TOF and retarding potential analysis (RPA) experiments indicate that the emission consists mostly of monomers and dimers, and that a small fraction (< 5%) of the beam might be composed of cluster ions with greater degrees of solvation. To conclude, the thesis reports on the etching properties of the beams obtained from ILIS, both in the case of traditional externally wetted tungsten sources and with the novel carbon xerogel emitter technology. The W ILIS etches silicon with sputtering rates between 6 and 35 atoms of silicon removed per incident ion at 15 keV irradiation energies, whereas the carbon xerogel ILIS has been used to etch gold, silicon and gallium nitride with sputtering rates in the order of 10 for irradiation energies between 2 and 7 keV.
