The choice of pricing model for software products is a complex procedure due to the different characteristics compared to physical products. This thesis investigates and compares software pricing models in a B2B setting, and describes how KAM plays a role in executing a pricing model. The research has been conducted as an opportunist case study on Adebro, a technology company in the B2B sector. The thesis have come to the following conclusions, with data from interviews and literature: Perpetual license is, and will continue to be, an attractive pricing model for Adebro. However, a subscription-based usage independent pricing model is also attractive for the future. Implications of switching pricing model would be largest when changing between a perpetual and subscription model, where revenue will have the most visual impact. The most important task for KAM is to communicate the change to current and new customers. KAM and the pricing model must also be structured to support each other to be successful. The thesis contributes to science by providing research on pricing models for manufacturing related software. However, studies concerning the weighting of importance for different pricing parameters would be of interest for the future.

Thesis (PhD)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: Efficient process design commonly relies on equation-of-state (EOS) models to provide reliable estimates of thermodynamic properties. The accuracy of EOS models, in turn, depends on the extent to which they account for intermolecular forces. The aim of this project was to improve the simplified Perturbed Chain - Statistical Associating Fluid Theory (sPC-SAFT), enabling it to account more accurately for complex molecular interactions. The more simple SAFT-based Cubic-Plus-Association (CPA) model was evaluated along similar lines for comparative purposes. A literature review showed that both sPC-SAFT and CPA have been widely applied in phase equilibria problems, but not extensively for the prediction of other thermodynamic properties. Consequently, an initial evaluation was performed on the ability of sPC-SAFT and CPA to predict first- and second-order thermodynamic properties. The properties of non-polar, polar and hydrogen bonding fluids were considered, showing that: a) sPC-SAFT and CPA generally predict first-order properties with the same accuracy, but sPC-SAFT provides improved predictions of second-order properties. Significant errors are, however, still observed with sPC-SAFT. b) A parameter regression study with sPC-SAFT, using model parameters obtained by including second-order properties in the regression function, results in poor predictions of the saturated vapour pressure and liquid density. c) Treating strong polar and dispersive forces together as Van der Waals forces results in many properties being poorly predicted by both sPC-SAFT and CPA. d) The major limitation of the association term in both CPA and sPC-SAFT is its inability to account for the influence of bond co-operativity, especially in alcohol/water mixtures. Based on these findings, the following improvements could be made: a) The development of a new association scheme for 1-alcohols, denoted the 2C association scheme. b) The extension of sPC-SAFT with the polar theories of Jog & Chapman (JC) and Gross & Vrabec (GV) to obtain sPC-SAFT-JC and sPC-SAFT-GV. c) The extension of CPA with modified versions of the aforementioned polar theories to obtain CPA-JC and CPA-GV. d) The development of a new ‘universal’ cross-association approach. The new 2C association scheme consists of one bipolar association site and one negative electron donor site and is a combination of the 1A and 2B/3B association schemes. Modelling 1-alcohols with the 2C scheme in sPC-SAFT results in improved VLE predictions of alcohol/water and alcohol/alcohol mixtures, but alcohol/alkane VLE is predicted less accurately compared to the 2B and 3B association schemes. sPC-SAFT-JC and sPC-SAFT-GV provide improved VLE predictions of mixtures with non-associating polar components compared to sPC-SAFT. VLE of polar/alkane and polar/polar systems can be represented accurately with no or only very small binary interaction parameters (BIPs). CPA-JC and CPA-GV also enable improved VLE predictions of the polar/alkane and polar/polar mixtures compared to CPA. sPC-SAFT-GV and sPC-SAFT-JC were also applied to several mixtures of associating components including alcohol/alkane, alcohol/alcohol and alcohol/water systems. New alcohol model parameters for both sPC-SAFT-GV and sPC-SAFT-JC based on the 2C, 2B and 3B association schemes were determined. The predictions of both sPC-SAFT-GV and sPC-SAFT-JC, based on any of the three association schemes, provide similar alcohol/alkane and alcohol/alcohol VLE representations, but the best phase equilibria predictions of water/alcohol systems are obtained when alcohols are modelled with the newly proposed 2C association scheme. The usefulness of a new ‘universal’ cross-association approach was demonstrated with both sPC-SAFT-GV and sPC-SAFT-JC. The philosophy behind the new approach is to set the association volume value of the solvating component equal to the cross-associating volume value of the 1-alcohol of the same molecular size and to determine an association energy value from binary VLE data. This approach aims to characterize the solvating behaviour of the cross-associating component. Preliminary results are demonstrated with systems containing acetone, propyl formate and ethyl acetate. Other thermodynamic properties, such as excess enthalpy and excess volume can be described with the new polar sPC-SAFT and CPA models. In the majority of cases, improvements are observed compared to the normal sPC-SAFT and CPA models, but BIPs are still required to obtain accurate correlations. However, these BIPs cannot be used in phase equilibria calculations and are generally property-specific. To summarise: Through the development of the 2C scheme, and the incorporation of polar terms into the sPC-SAFT model structure, notable improvement in the VLE predictions of polar (nonhydrogen bonding)/alkane, alcohol/alkane, alcohol/water and polar/alcohol systems could be obtained if compared to the original sPC-SAFT EOS. As such, the research pesented in this thesis encapsulates some significant novel contributions, viz.: a) A systematic evaluation of sPC-SAFT and CPA, providing better insight into their ability to predict thermodynamic properties. b) The development of the new 2C association scheme for 1-alcohols, as published in Ind. Eng. Chem. Res. 2011, 50, 8711–8725. c) The extension of sPC-SAFT with the polar theories of JC and GV, with application to non-associating components, as published in Fluid Phase Equilib. 2011, 305, 174–184. d) The extension of CPA with the JC and GV polar theories, as published in Fluid Phase Equilib. 2011, 312, 66–78. e) The application of sPC-SAFT-GV and sPC-SAFT-JC to associating components, including results with the new 2C association scheme. f) The development of the new ‘universal’ cross-association approach. / AFRIKAANSE OPSOMMING: Doeltreffende prosesontwerp steun grotendeels op toestandvergelykings (EOS) om goeie skattings van vloeistofeienskappe te voorspel. Die akkuraatheid van hierdie modelle word bepaal deur hoe goed hulle die invloed van molekulêre kragte kan naboots. Die doel van hierdie projek was dus om die ‘simplified Perturbed Chain-Statistical Associating Fluid Theory’ (sPC-SAFT) te verbeter, sodat dit komplekse molekulêre kragte beter kan beskryf. Die meer vereenvoudigte SAFT-gebaseerde ‘Cubic-Plus-Association’ (CPA) model was ook geëvalueer vir vergelykende doeleindes. 'n Literatuurstudie het getoon dat beide sPC-SAFT en CPA reeds wyd toegepas is in fase ewewig probleme, maar nie vir ander termodinamiese eienskappe nie. Gevolglik, is 'n aanvanklike ondersoek uitgevoer waarin die vermoë van sPC-SAFT en CPA om eerste- en tweede-orde termodinamiese eienskappe te voorspel, geëvalueer is. Die eienskappe van nie-polêre, polêre en waterstof-bindinde komponente is oorweeg en die hoof bevindinge uit hierdie ondersoek is: a) sPC-SAFT en CPA voorspel oor die algemeen eerste-orde eienskappe met dieselfde akkuraatheid, maar sPC-SAFT bied verbeterde voorspellings van tweede-orde eienskappe. Beduidende foute is egter steeds teenwoordig in die voorspellings van sPC-SAFT. b) 'n Model parameter regressie studie met sPC-SAFT het getoon dat deur tweede-orde eienskappe ook in die regressie-funksie in te sluit, swak skattings van die eienskappe wat nodig is vir 'n goeie fase-ewewig voorspellings, verkry word. c) Die gesamentlike behandeling van sterk polêre en dispersie kragte as Van der Waals kragte, lei tot swak voorspellings van baie eienskappe deur sPC-SAFT en CPA. d) Die hoof beperking van die assosiasie term wat gebruik word deur beide CPA en sPC-SAFT, is die term se onbekwaamheid om die invloed van verbinding-samewerkings te beskryf, veral in mengsels van alkohole met water. Hierdie bevindings het as basis gedien om die volgende verbeterings aan te bring: a) Die ontwikkeling van 'n nuwe assosiasie skema vir 1-alkohole: die 2C-assosiasie skema. b) Die uitbreiding van sPC-SAFT met die polêre teorieë van Jog & Chapman (JC) en Gross & Vrabec (GV) om sPC-SAFT-JC en sPC-SAFT-GV onderskeidelik te kry. c) Die uitbreiding van CPA met gewysigde weergawes van die polêre teorieë om CPA-JC en CPA-GV te kry. d) Die ontwikkeling van ʼn nuwe ‘universele’ kruis-assosiasie benadering. Die nuut-voorgestelde 2C assosiasie skema bestaan uit een bipolêre assosiasie sone en een negatiewe elektron skenker sone en is ʼn kombinasie van die 1A en 2B/3B assosiasie skemas. Die modellering van 1-alkohole met die 2C skema in sPC-SAFT lei tot 'n verbetering in damp-vloeistof ewewig (VLE) voorspellings van alkohol/water en alkohol/alkohol sisteme, maar vir alkohol/alkaan sisteme is minder akkurate voorspellings verkry in vergelyking met die 2B en 3B assosiasie skemas. sPC-SAFT-JC en sPC-SAFT-GV lewer beter VLE voorspellings van mengsels met nie-assosiërende polêre komponente in vergelyking met sPC-SAFT. Die VLE van polêre/alkaan en polêre/polêre stelsels kan akkuraat beskryf word deur beide modelle wanneer geen of baie klein binêre interaksie parameters (BIPs) gebruik word. CPA-JC en CPA-GV lewer ook verbeterde VLE voorspellings van polêre/alkaan en polêre/polêre mengsels in vergelyking met CPA. sPC-SAFT-GV en sPC-SAFT-JC is ook toegepas op verskeie assosiërende mengsels, insluitend: alkohol/alkaan, alkohol/alkohol en alkohol/water stelsels. Nuwe alkohol parameters is vir beide sPC-SAFT-GV en sPC-SAFT-JC bepaal gebaseer op die 2C, 2B en 3B assosiasie skemas. Die voorspellings van sPCSAFT- GV en sPC-SAFT-JC, gebaseer op enigeen van die drie assosiasie skemas, lewer soortgelyke alkohol/alkaan en alkohol/alkohol VLE voorspellings, maar die beste fase-ewewig voorspellings vir water/alkohol sisteme is verkry wanneer alkohole gemodelleer word met die 2C assosiasie skema. Die nuwe ‘universele’ kruis-assosiasie benadering is gedemonstreer met beide sPC-SAFT-GV en sPC-SAFT-JC. Die filosofie agter die nuwe benadering is om die assosiasie volume waarde van die solverende komponent gelyk te stel aan die kruis-assosiasie volume waarde van die 1-alkohol met dieselfde molekulêre massa. Die assosiasie energie waarde word dan bepaal vanaf binêre VLE data. Hierdie benadering poog om die solverende gedrag van die kruis-assosiërende komponent meer akkuraat te karakteriseer. Voorlopige resultate met mengsels van asetoon, propiel formaat en etiel asetaat dui aan dat merkwaardige verbeterings in VLE voorspellings gekry word. Ander termodinamiese eienskappe, soos oortollige entalpie en oortollige volume, is ook ondersoek met die nuwe polêre sPC-SAFT en CPA-modelle. In meeste gevalle word verbeterde resultate gekry in vergelyking met die oorspronklike sPC-SAFT en CPA modelle, maar groot BIPs word steeds benodig om aanvaarbare korrelasies te kry. Hierdie BIPs kan egter nie gebruik word vir fase-ewewig voorspellings nie en is eienskap-spesifiek. Om op te som: deur die ontwikkeling van die 2C skema, en insluiting van die polêre terme in die sPC-SAFT model struktuur, is merkwaardige verbeterings in die VLE voorspellings van polêre/alkaan, alkohol/alkaan, alkohol/water en polêre/alkohol sisteme gekry in vergelyking met die oorspronklike sPC-SAFT EOS. Die navorsing voorgelê in hierdie tesis het dus gelei tot die volgende nuwe bydraes: a) Die sistematiese evaluering van die vermoë van sPC-SAFT en CPA om termodinamiese eienskappe te voorspel. b) Die ontwikkeling van die nuwe 2C assosiasie skema vir 1-alkohole soos gepubliseer in Ind. Eng. Chem. Res. 2011, 50, 8711–8725. c) Die uitbreiding van sPC-SAFT met die polêre teorieë van JC en GV soos gepubliseer in Fluid Phase Equilib. 2011, 305, 174–184. d) Die uitbreiding van CPA met die polêre teorieë van JC en GV soos gepubliseer in Fluid Phase Equilib. 2011, 312, 66–78. e) Die toepassing van hierdie nuwe modelle op assosiërende komponente, insluitend resultate met die nuwe 2C skema. f) Die ontwikkeling van ʼn nuwe kruis-assosiasie benadering.

Thesis (MScEng)-- Stellenbosch University, 2013. / ENGLISH ABSTRACT: The simplified Perturbed-Chain Statistical Associating Fluid Theory (sPC-SAFT) is characterised by the dual advantages of decreased computational intensity, while remaining accurate for a variety of systems. Vapour-liquid equilibrium data are used to generate equation of state parameters. However, incorporating monomer fraction data into the parameter regression has long been advocated as a good, or even preferred, practice. Therefore, the monomer fraction data of dilute alcohol-acetone systems were analysed in this study. A small stainless steel sample vessel was constructed with temperature control, manual pressure control and a mechanism for liquid phase analysis via infrared spectroscopy. The performance of the spectrometer was verified by comparison with the ethanol – n-hexane data of von Solms et al. (2007), after which new monomer fraction data were obtained for dilute solutions (between 0.01 and 1.5 mol%) of methanol, ethanol, 1-propanol and 2-propanol in acetone near 23 °C. For dilute alcohol-acetone systems it was found that the propanols had the highest monomer fractions, and methanol the lowest. With increasing alcohol concentration, the monomer fractions decreased exponentially to values of 0.4 and 0.1 for methanol and the other alcohols respectively. The excess availability of hydrogen bond acceptors in the mixtures explains the equivalency observed for ethanol, 1-propanol and 2-propanol. For dilute acetone-alcohol systems it was found that, especially for methanol and ethanol, there was a pronounced trend towards acetone monomer fractions of 1 at infinite dilution. For the acetone – 2-propanol system, a previously unrecorded monomer peak was observed and quantified. Acetone monomer fractions tended to decrease as alcohol chain-length increased, showing that acetone could more easily penetrate the hydrogen bond network of the solvent when the solvent-solvent bonds were weaker. Monomer fraction data were compared to predictions for the sPC-SAFT scheme and parameters combinations published in the literature. The experimental data were accurately modelled using modified association parameters such that the solute associates strongly (εAB≈103 κ≈1), while the solvent parameters were decreased (εAB≈102 κ≈10˗3) to give a weakened solvent association effect. The difficulty for the dilute solute in penetrating the solvent bonding network appeared to be similar to the hydrophobic effect. Two new association schemes were proposed for acetone, assigning a single (N) or two (2N) negative association sites to represent the oxygen valence electron pairs. These schemes showed relative success in modelling acetone as the solvent in the mixture, while not being able to predict acetone monomer fractions when acetone was the solute. For dilute acetone-alcohol systems, the data were best described using the 2B model for acetone, while the best choice of scheme for the alcohol varied from system to system. For dilute alcohol-acetone mixtures it was generally found that a 2B-N model (with modified association parameters) provided the best fit to those experimental data. Accurate modelling below 0.1 mol% was difficult to attain with average errors decreasing to the order of 10% when this area was excluded. In this highly dilute region, not one of the models could describe the rapid change in (monomer fraction) gradient sufficiently while simultaneously offering accurate predictions over the entire experimental range. / AFRIKAANSE OPSOMMING: Die sPC-SAFT of simplified Perturbed-Chain Statistical Associating Fluid Theory toestandsvergelykings word wyd gebruik as gevolg van sy goeie akkuraatheid vir ‘n wye reeks sisteme, ten spyte van verminderde berekeningsintensiteit. Die parameters vir dié toestandsvergelyk word afgelei van faseewewig data, maar monomeer fraksie data word voorgestel vir die verbetering van (veral) die assosiasie parameters. Ten opsigte hiervan, was alkohol-asetoon sisteme bestudeer en hul monomeer fraksies gemeet. ‘n Staal reaktor was ontwerp (met ‘n temperatuurbeheerstelsel sowel as drukbeheer) om vloeistof monsters voor te berei vir analise d.m.v. infrarooi-spektroskopie. Die akkuraatheid van die eksperimentele apparaat is bewys deur nabootsing van etanol – n-heksaan data van von Solms et al. (2007), waarna nuwe monomeer fraksie data gegenereer is vir verdunde mengsels (0.01 tot 1.5 mol%) van metanol, etanol, 1- en 2-propanol met asetoon by 23 °C. Metanol monomeer fraksies het eksponensieël afgeneem na 0.4, terwyl etanol en propanol fraksies afgeneem het na ‘n gemene waarde van ongeveer 0.1. Hierdie tendens word toegeskryf aan ‘n oormaat van toeganklike waterstofbindingontvangers in hierdie mengsels. Vir verdunde asetoon-alkohol sisteme is daar ‘n tendens, (veral vir verdunnings met metanol en etanol) vir die monomer fraksies om te neig na 1 by oneindige verdunning. ‘n Monomeer piek is ook waargeneem vir die asetoon – 2-propanol sisteem. Hierdie piek is nie voorheen gesien in ander studies nie en dit is ook die eerste keer wat sulke data gekwantifiseer is. Daar is bevind dat asetoon monomeer fraksies afneem soos alkohol kettinglengte toeneem. Die gegenereerde monomeer fraksie data word vergelyk met verskeie sPC-SAFT parameterstelle vanuit die literatuur. Oor die algemeen, is die beraamde fraksie veel hoër as die eksperimentele data wanneer die 2B/3B/2C skemas met ‘n nie-assosiërende asetoon molekuul gemodelleer word. Wanneer die 2B parameters van von Solms et al. (2004) gebruik word, toon die beraming ‘n drastiese onderskatting van die data. Om ‘n akkurate beraming van die monomeer fraksie data te kry, moet die assosiasie parameters van die opgeloste stof vermeerder word (met εAB≈103 κ≈1) terwyl die oplosmiddel s’n drasties verswak moet word (met εAB≈102 κ≈10-3). Hierdie patroon kan vergelyk word met die hidrofobiese effek waar die kragte binne die oplosmiddel ‘n netwerk vorm wat die opgeloste stof uitstoot. Twee nuwe assosiasie skemas word ook voorgestel vir asetoon waar onderskeidelik een (N) en twee (2N) negatiewe sones, wat die valenselektroonpare op die suurstofatoom voorstel, aan asetoon geheg word. Hierdie twee skemas het relatiewe sukses getoon in die modellering van verdunde alkohol-asetoon sisteme terwyl dit ‘n swak beskrywing van die verdunde asetoon-alkohol mengsels voorspel het. ‘n Gewysigde 2B asetoon skema gee ‘n goeie beskrywing van die eksperimentele data. In hierdie geval, is die keuse van alkohol skema minder belangrik, terwyl die waardes van die assosiasie parameters verminder moet word. Vir verdunde alkohol-asetoon mengels word daar bevind dat ‘n 2B-N model met nuwe assosiasie parameters die beste passing van die eksperimentele data gee. Daar was ook bevind dat die modelle se akkuraatheid drasties afneem (met fout vermeerdering in die orde van 10%) wanneer die konsentrasie van die opgeloste stof minder as 0.1 mol% is.

不動產證券化除了「小口化」不動產，讓投資人也能參與金額龐大的不動產投資外，其價格的穩定亦發揮保值效果。除了使一般社會大眾能穩定獲利，退休的老年人口的資金，亦有一較安全的出口。不動產證券化背後所隱藏的政策效果，則是避免財團壟斷不動產資源，所以政府在政策上應當鼓勵不動產證券化之發展。有鑑於此，有關不動產證券化，在政策上則應採開放的態度，立法上應較大幅度之鬆綁，審查流程更應採便民的措施，甚至准許國外的REITs在台發行。 然不動產投資畢竟金額龐大且專業，一般社會大眾無法解其堂奧，政府當然有責任在開放的同時，加諸安全與規避經營風險的立法與監督，俾能不動產證券化健全的進行。本研究即針對目前國內不動產證券化的立法上與審查程序上之開創性與不合理性，提出看法與建議。如REITs發行時，不動產估價之公平性、成立SPC 制、允許REITs的增資與合併、開放開發型的REITs等均論述其優、劣，並作成建議。而政府也應採開放的態度，既啟動不動產證券化的列車，即不應半途再加諸太多的限制，造成不動產證券化發展不順暢。以目前台灣已發行量觀之，投資人要發揮不動產證券化之避險與穩定獲利之功能，分散財團不動產持有比例、加速都市更新速度，實在是能量不足。 期盼主管官署，放眼未來，取國外證券化發展之長處，重新本著與國際接軌之精神，修訂不動產證券化法及其相關法令與新審查辦法。唯有法令鬆綁，不動產證券化良效始能反應在我國股市與不動產市場，讓社會大眾均能參與不動產投資與分享不動產開發之利益。新增加的金融商品才得以循序漸進，分散社會資金的投資風險。 / REITs enables individual investors to participate in the large real estate investment through securitization. There are some benefits of REITs investment such as the stability of its price, also highly probability of capital gain. REITs can not only generate stable income for the public but also provides a safer investment tool for pension fund. The government policy should encourage the securitization of real estate in order to avoid the financial group monopolizing the real estate resources. Therefore, government supervising bureau should be more open-minded for deregulation and even allows overseas REITs to emit in Taiwan. Nevertheless, due to its huge amount and specialization, real estate investment seems not tangible for the majority of social populace. The government certainly has the responsibility to provide a safer environment through regulation and supervision in order to enhance the integrity of securitization development. This research aims at the development of REITs in Taiwan, and proposes some views and suggestions. For example when REITs is being released, the fairness of its valuation、SPC system、increasing capital、 merging, and regulation innovation of development REITs. The government should be more open-minded to avert balk the development of REITs because of too much limitations. The volume of present REITs circulation in Taiwan is still not large enough to accelerate city renewal、diversify real estate holding by the tycoons, and stable the profit for the investors. Hoping the authorities can have great visions and absorb the knowledge of securitization from other countries to scheme more mature regulations, and take broader views. Only if the deregulation can not only enable everyone participate and benefit from real estate securitization but diversify investment risk.

Nouryon, formerly Akzo Nobel, is a world-leading manufacturer of particles. Already in the 70s, one part of Nouryon was founded in Stockvik where to this day still produce particles of the highest class. When the production of particles is classified under the chemical process industry, the manufacturing process consists of a number of raw materials mixed and reacting with each other in different vessels. Many of the chemicals used are harmful to human health and therefore Nouryon is constantly working to increase safety while at the same time a great focus is on streamlining the manufacturing process. The purpose of the work is to reduce the variation in the manufacturing process by analyzing a particular product family, working with tools based on statistics and historical data, and automatic inspection systems with the basis in camera technology. By reducing the variation, the proportion of First Time Right will increase, which in turn results in reduced costs that arise due to rework. It would also facilitate production planning, reduce downtime for subsequent processes and generally result in a generally more reliable process. By raising the root causes of the variation and addressing these with the help of tools that simplify the daily work, control of the process can be taken and the needs of the customers be ensured. To create an understanding of the chemical process, a current study of how different manufacturing steps were carried out. In addition to this, it was also investigated how the company is currently working on raising problems to the surface and in order to be able to determine how the work with the statistical tools and the inspection system could be fullfilled in the current conditions. The work resulted in a large amount of data that was the basis for a multivariate analysis, a number of proposals for future work and also two separate reports discusses with statistical process control and inspection systems with camera technology. Unfortunately, no quantitative results can be presented in the work because all results are based on actions taken in the longer term.

The objective of this study is to evaluate the quality of the process of the mechanized harvest of raw sugar cane by means of statistical process control, and also the capacity of the process to generate results within the specified limits through the analysis of capability, quantifying the losses and damages caused to the stalks (ratoon) by the mechanism of the cutting base. The experiment was conducted in an area of yellow clay soil located in the municipal of Arez, RN, Brazil, using two methods of managing the soil within the conventional system of preparation. The treatments were: (a) moldboard ploughs followed by average weight offset disc harrow and; (b) heavy offset disc harrow followed by average weight offset disc harrow, with the losses being determined through samples. The losses attributed to splinted stalks, pieces and stubble total differed statistically between the treatments studied, being that the highest values of quantified losses came from the treatment using moldboard ploughs followed by average weight offset disc harrow. The harvesting process proved unmanageable due to splinted stalks, whole cane, cane points, fixed pieces, loose pieces and splinters. The treatment using moldboard ploughs followed by average weight offset disc harrow presented the highest degree of damage to the stalks when compared to treatment (b). The treatment (a) presented the largest area of microrelief, differing statistically from the treatment using heavy offset disc harrow followed by average weight offset disc harrow.

After removing points affected by root causes, the process is still not in control. Further investigations are needed to get the process in control. Examples of where to go next is presented in the report. In the DOE part a four factor full factorial experiment was performed. The goal with the experiment was to find how different factors affects switch time and life length of an electrochromic display. The four factors investigated were: Electrolyte, Additive, Web speed and Encapsulation. All statistical analysis was performed using Minitab 14. The analysis of measurements from one day and seven days after printing showed that: - Changing Electrolyte from E230 to E235 has small effect on the switch time - Adding additives Add1 and Add2 decreases the switch time after 1 and 7 days - Increasing web speed decreases the switch time after 1 and 7 days - Encapsulation before UV-step decreases the switch time after 7 days

Statistical process control (SPC) is a toolbox to detect changes in the output of a process distribution. It can serve as a valuable resource to maintain high quality in a manufacturing process. This report is based on the work on evaluating and implementing methods for SPC in the process of chromatography instrument manufacturing at GE Healthcare, Umeå. To handle low volume and non-normally distributed process output data, non-parametric methods are considered. Eight control charts, three for for Phase I analysis, and five for Phase II analysis, are evaluated in this study. The usability of the charts are assessed based on ease of interpretation and the performance to detect distributional changes. The later is evaluated with simulations. The result of the project is the implementation of the RS/P-chart, suggested by Capizzi et al (2013), for Phase I analysis. Of the considered Phase I methods (and simulation scenarios), the RS/P-chart has the highest overall probability, of detecting a variety of distributional changes. Further, the RS/P-chart is easily interpreted, facilitating the analysis. For Phase II analysis, the use of two control charts, one based on the Mann-Whitney U statistic, suggested by Chakraborti et al (2008), and one on the Mood test statistic for dispersion, suggested by Ghute et al (2014), have been implemented. These are chosen mainly based on the ease of interpretation. To reduce the detection time for changes in the process distribution, the change-point chart based on the Cramer Von Mises statistic, suggested by Ross et al (2012), could be used instead. Using single observations, instead of larger samples, this chart is updated more frequently. However, this efficiently increases the false alarm rate and the chart is also considered much more difficult to interpret for the SPC practitioner. / Statistisk processkontroll (SPC) är en samling verktyg för att upptäcka förändringar, i fördelningen, hos utfallen i en process. Det kan fungera som en värdefull resurs för att upprätthålla en hög kvalitet i en tillverkningsprocess. Denna rapport är baserad på arbetet med att utvärdera och implementera metoder för SPC i en monteringsprocess av kromatografiinstrument på GE Healthcare, Umeå. Åtta styrdiagram, tre för för fas I analys, och fem för fas II analys, studeras i denna rapport. Användbarheten hos styrdiagrammen bedöms efter hur enkla de är att tolka och förmågan att upptäcka fördelningsförändringar. Den senare utvärderas med simuleringar. Resultatet av projektet är införandet av RS/P-metod, utvecklad av Capizzi et al (2013), för analysen i fas I. Av de utvärderade metoderna, (och simuleringsscenarier), har RS/P-diagrammet den högsta övergripande sannolikheten, för att upptäcka en mängd olika fördelningsförändringar. Vidare är metodens grafiska diagram lätt att tolka, vilket underlättar analysen. För fas II analys, har två styrdiagram, ett baserat på Mann-Whitney's U teststatistika, som föreslagits av Chakraborti et al (2008), och ett på Mood's teststatistika för spridning, som föreslagits av Ghute et al (2014), implementerats. Styrkan i dessa styrdiagram ligger främst i dess enkla tolkning. För snabbare identifiering av processförändringar kan styrdiagrammet baserat på Cramer von Mises teststatistika, som föreslagits av Ross et al (2012), användas. Baserat på enskilda observationer, istället för stickprov, har styrdiagrammet en högre uppdateringsfrekvens. Detta leder dock till ett ökat antal falska larm och styrdiagrammet anses dessutom vara avsevärt mycket svårare att tolka för SPC-utövaren.

SCPs have experienced growth of their importance and use in recent years being found in the structure of various types of business, particularly in real estate and investments. As one of the types of companies allowed by law, the SCPs have great plasticity in their use, adapting to the diverse needs of its members. Some specific features, however, must be observed by the parties, at the risk of their disconsideration of the legal entity. This is the case of the role of the silent partners, who cannot be involved in the execution of the SCP object, or contribute to the formation of its special equity with services that are directly related to its object. And the risks go beyond those provided for in the Civil Code, that indicate solidarity with the active partner of the silent partner before affected third parties. From a tax perspective, there may be a disconsideration of the legal entity of the SCP to consider the provision of services, where taxes are incurred on payments made to the silent partner as dividends. Other risks and consequences of adopted business models are explored and highlighted throughout the paper, in which SCPs are used to conceal a legal situation in order to exploit an advantage. This applies to the distribution of profits forecast SCP with assets or such and not with capital, could conceal a purchase agreement, and when such SCP is formed by a group of people, could conceal a consortium for delivery of assets, governed by Law 11.795/2008. Public disclosure of an SCP, in order to attract investors, could characterize the operation as a collective investment contract, regulated by Law 6.385/1976. At the end there are some precautions listed, as a suggestion, to be observed to avoid the risks indicated throughout this paper. / Este trabalho se dispõe a analisar as características das sociedades em conta de participação ou SCP’s, seus principais usos, os riscos de sua descaracterização e suas respectivas consequências. As SCP’s experimentaram crescimento de sua importância e uso nos últimos anos, sendo constatadas na estruturação de diversos tipos de negócios, com destaque na área imobiliária e na realização de investimentos. Como um dos tipos societários admitidos pela legislação, as SCP’s possuem grande plasticidade em sua utilização, adaptando-se às diversas necessidades de seus usuários. Algumas características específicas, no entanto, devem ser observadas pelas partes, sob risco de sua descaracterização. É o caso do papel dos sócios participantes, que não poderão se envolver na execução do objeto da SCP, nem contribuir para a formação do seu patrimônio especial com serviços que tenham relação direta com o seu objeto. E os riscos vão além daqueles previstos no Código Civil, que aponta a solidariedade, com o sócio ostensivo, do sócio participante perante terceiros afetados. Do ponto de vista fiscal, poderá haver a descaracterização da SCP para se considerar a prestação de serviços, quando ocorrerá a incidência de tributos sobre os pagamentos feitos ao sócio participante a título de dividendos. Outros riscos e consequências em modelos de negócio adotados foram explorados e apontados ao longo do trabalho, em que as SCP’s são utilizadas para dissimular uma situação jurídica, de modo a gozar de alguma vantagem. É o caso da previsão de distribuição de resultado em SCP com bens ou coisa certa e não com capital, poderia dissimular um contrato de compra e venda, e quando tal SCP for formada por um grupo de pessoas, poderia dissimular um consórcio para entrega de bens, regido pela Lei 11.795/2008. A divulgação pública de SCP, para captação de investidores, poderia caracterizar a operação como um contrato de investimento coletivo, regulado pela Lei 6.385/1976. Ao final foram listados, como sugestão, alguns cuidados a serem observados para se evitar os riscos apontados ao longo deste trabalho.
