Ferdous, Arundhoti. "Comparative Analysis of Tag Estimation Algorithms on RFID EPC Gen-2 Performance." Scholar Commons, 2017. http://scholarcommons.usf.edu/etd/6837.
Full textAbstract:
In a passive radio-frequency identification (RFID) system the reader communicates with the tags using the EPC Global UHF Class 1 Generation 2 (EPC Gen-2) protocol with dynamic framed slotted ALOHA. Due to the unique challenges presented by a low-power, random link, the channel efficiency of even the most modern passive RFID system is less than 40%. Hence, a variety of methods have been proposed to estimate the number of tags in the environment and set the optimal frame size. Some of the algorithms in the literature even claim system efficiency beyond 90%. However, these algorithms require fundamental changes to the underlying protocol framework which makes them ineligible to be used with the current hardware running on the EPC Gen-2 platform and this infrastructure change of the existing industry will cost billions of dollars. Though numerous types of tag estimation algorithms have been proposed in the literature, none had their performance analyzed thoroughly when incorporated with the industry standard EPC Gen-2. In this study, we focus on some of the algorithms which can be utilized on today’s current hardware with minimal modifications. EPC Gen-2 already provides a dynamic platform in adjusting frame sizes based on subsequent knowledge of collision slots in a given frame. We choose some of the popular probabilistic tag estimation algorithms in the literature such as Dynamic Frame Slotted ALOHA (DFSA) – I, and DFSA – II, and rule based algorithms such as two conditional tag estimation (2CTE) method and incorporate them with EPC Gen-2 using different strategies to see if they can significantly improve channel efficiency and dynamicity. The results from each algorithm are also evaluated and compared with the performance of pure EPC Gen-2. It is important to note that while integrating these algorithms with EPC Gen-2 to modify the frame size, the protocol is not altered in any substantial way. We also kept the maximum system efficiency for any MAC layer protocol using DFSA as the upper bound to have an impartial comparison between the algorithms. Finally, we present a novel and comprehensive analysis of the probabilistic tag estimation algorithms (DFSA-I & DFSA-II) in terms of their statistically significant correlations between channel efficiency, algorithm estimation accuracy and algorithm utilization rate as the existing literature only look at channel efficiency with no auxiliary analysis. In this study, we use a scalable and flexible simulation framework and created a light-weight, verifiable Gen-2 simulation tool to measure these performance parameters as it is very difficult, if not impossible, to calculate system performance analytically. This framework can easily be used to test and compare more algorithms in the literature with Gen-2 and other DFSA based approaches.

Full textAbstract:
While government contracting out its work continues to proliferate and studies about this phenomenon have increased during the past two decades, still little is known about how effective government sponsored networks are at managing broad and complex networks of primarily non-governmental entities.
This dissertation reports the results of one such investigation, which examined a U.S. federal agency's contracting experiences in evidence-based health care. The Agency for Healthcare Research and Quality (AHRQ) is a unit of the U.S. Department of Health and Human Services (HHS). Among other tasks, AHRQ supports the development and dissemination of evidence about current best practices in health services delivery through its Evidence-based Practice Center (EPC) programs that contract out its work and operate in broad and complex network.
The purpose of this study was to examine the extent to which AHRQ's EPC Program I was effective in supporting the translation of evidence reports and disseminating the products to the public by contracting with public and non-profit entities to do the work. This dissertation also sought to examine the extent to which the evidence reports and derivative products were publicly accessible by operationalizing the objectives articulated in AHRQ's authorizing legislation in a manner consistent with theories of representative democracy and exploring Program I's effectiveness using William T. Gormley's ideas (1989; Gormley & Balla 2003) of bureaucratic control.
The results from this dissertation suggest that a decentralized network was related to overall higher translation and dissemination network effectiveness. Specifically, the findings from this study suggest that a decentralized network was related to overall higher translation and dissemination network effectiveness. Also, weak ties among the network actors when transferring complex knowledge was associated with higher translation and dissemination network effectiveness on the whole.
The findings from this dissertation also contribute to network theory by extending Gormley's bureaucratic control typology (1989; Gormley & Balla 2003) to the network level, and also to the type of control that was available to the Agency over the network. Finally, the results contribute to better understanding of the dynamics that can be associated with the effectiveness of similar programs.<br>Ph. D.

Frota, de Albuquerque Landi Fabiana. "Energy Performance Contracting in Swedish scenario: a case study with Morastrand AB." Thesis, Högskolan Dalarna, Energiteknik, 2018. http://urn.kb.se/resolve?urn=urn:nbn:se:du-28667.
Full textAbstract:
Renovation of the existing buildings in Sweden represents a great potential to achieve the energy efficiency and carbon emission targets set by the European Union and the Swedish government. The Energy Performance Contracting (EPC) is regarded as an efficient way to manage and to outsource the risks of energy efficiency (EE) measures. The thesis aims to identify the theoretical framework of EPC in the Swedish scenario and, through a real case, develop a model that relates EE measures and its results considering the capital investment versus running costs of renovation projects. The work is based on the incorporation with the Morastrand AB. The research expects to assess EPC processes and measures as in Energy Service Companies (ESCO) and consequently help in the decision making and the management of the projects. The thesis is composed of two parts. The first part identifies the theoretical framework of energy contract models focusing on the EPC, while a case study with Morastrand AB is subsequently presented. It is suggested one approach for the preliminary comparison of different renovation measures in EE projects, corresponding to the first step of the planning phase of an EPC. General recommendations and sensitive factors were identified and can assist Morastrand AB to effectively implement EE projects in the future. For orienting investments, the Lifecycle Cost Analysis (LCCA) is a method to study solutions under economic aspects and further it can be extended to the complete Lifecycle Assessment of the upcoming projects. The theoretical framework of the EPC is composed by identifying the projects, performing the technical analysis, determinizing the potential in energy savings, deepening the analysis with auditions, tendering the project, designing and executing the project, commissioning, operating and supporting the systems with constant monitoring and maintenance. The biggest challenge for the EPC in Sweden is the relation between the ESCOs and their clients. The figure of the facilitator could improve the results and balance the knowledge gap between the parts. The actors of these projects are the ESCO, the client, the facilitator and the financing part. In Sweden, very frequently the client finances the operation. There are a few models of contracting, and the most popular are guaranteed savings and shared savings. The thesis performed the LCCA of three options for window replacement in a building at the end of its lifespan. The results show that the trends in prices and interest rates are sensitive factors. In this case, the projects with higher initial investments were more profitable. Those solutions can shield the company against energy prices escalates and contribute to the green policies.

Full textAbstract:
The UK’s housing stock is among the oldest and least efficient in Europe. 85% of the UK’s existing homes will still be standing and in use in 2050. Improving the energy efficiency of UK housing stock is an essential requirement in order for the UK to meet its 2008 Climate Change Act obligations. Energy efficiency in buildings is the focus of European (EU) policies with the intention of creating a low-carbon economy by 2020. Reducing energy consumption in existing buildings is essential to achieving this. Government policies are the primary mechanism for lowering energy consumption through changing consumer behaviour, promoting low carbon technology and energy efficient renovations of old building stock.The objective of this thesis is to investigate the effectiveness of UK policies at addressing factors affecting consumer decisions to carry out energy efficient renovations. This is with the intention of determining if UK policies are effectively contributing to the government’s long term climate change commitments.Using a theory developed by Parker (2000) as a conceptual framing of policy compliance, this study conducts interviews with consumers in order to analyse their awareness, understanding and perception of UK energy efficiency policies. Therefore, it can be determined how effective policies are at affecting consumer decisions to carry out energy efficient renovations.The thesis informs that consumers are motivated and willing to comply with policies but there are several key barriers preventing them from complying with these policies and therefore adopting energy efficient renovations. Policies are deemed to be somewhat ineffective at affecting consumer decisions to carry out energy efficient renovations.

Full textAbstract:
Business process modeling plays an important role for the documentation and analysis of organizational processes and for the specification of requirements for information systems. Currently, there are many standards for process modeling, and each represents a different approach to modeling and provides different opportunities for creating models. Thus, same models created in different modeling languages differ in terms of their expressiveness, according to each standard. The goal of this thesis is to evaluate the effectiveness of selected business process modeling standards. The effectiveness of standards will be evaluated on two levels. First, in terms of their semantics and second, in terms of their syntax. Evaluation of standards in terms of their semantics will be based on the comparison of standards with a business process metamodel created within the project Opensoul. This model defines a set of basic elements and their associations at a basic level of process modeling. Evaluation of standards in terms of their syntax will be based on the comparison of standards with a framework proposed by Moody and Hillegersberg. The results of this comparison should show which standard best supports defined criteria. The evaluation framework will be applied on the following process modeling standards: BPMN, EPC and IDEF3. Based on the results obtained their strength and weaknesses will be discussed. The main contribution of this thesis can be seen both in the analysis of the element set of selected process modeling standards and further in the comparison of standards according to the evaluation framework.

Full textAbstract:
Elliptic curve cryptography (ECC) is extensively used in various multifactor authentication protocols. In this work, various recent ECC based authentication and key exchange protocols are subjected to threat modeling and static analysis to detect vulnerabilities, and to enhance them to be more secure against threats. This work demonstrates how currently used ECC based protocols are vulnerable to attacks. If protocols are vulnerable, damages could include critical data loss and elevated privacy concerns. The protocols considered in thiswork differ in their usage of security factors (e.g. passwords, pins, and biometrics), encryption and timestamps. The threatmodel considers various kinds of attacks including denial of service, man in the middle, weak authentication and SQL injection. Countermeasures to reduce or prevent such attacks are suggested. Beyond cryptanalysis of current schemes and proposal of new schemes, the proposed adversary model and criteria set forth provide a benchmark for the systematic evaluation of future two-factor authentication proposals.

Full textAbstract:
The scope of this thesis is the field of business process modeling and additionally the usability of business process models in areas like conceptual analysis of IS/ICT, business process reengineering and business process management. For the purpose of evaluation of the usability of current standards for business process modeling, an framework for comparison of various characteristics of these standards is proposed. This thesis has two aims. Primarily, to develop an approach for evaluation of business process modeling standards, and as a secondary aim, to apply this evaluation model onto a set of selected standards for business process modeling and thus perform a comparison of these standards. The evaluation model has two main components. The first part is to create a set of characteristics which represent two existing points of view onto the exploitability business process modeling (e.g. during the development of IS/ICT and during BPR/BPM1). During the identification of particular characteristics, a research into the related literature and other sources has been performed to provide a sufficient basis for this activity. The second part of the developed approach is to the application of PEMM (Process & Enterprise Maturity Model), which was developed by Dr. M. Hammer for the purpose os auditing the maturity of business processes. Both of these parts are then put together into one evaluation framework. Based on information gathered from the respective specifications of particular standards, related literature and articles, we've performed an application of this evaluation framework on three standards for business process modeling: EPC, BPMN and IDEF3. The benefits of this thesis could be seen as a creation of a very own approach for evaluation of business process modeling standards. Additionally by performing the comparison of these three standards for business process modeling we've created a guideline which could be there fore applied by the potential reader during the decision making of what standard to use for business process modeling (in the context of expected purpose of this modeling).

Full textAbstract:
Bombardier Transportation in Västerås is developing traction system for trains. These systems must comply with Electromagnetic Compatibility (EMC) standards. Harmonics generated by the traction system is an EMC concern. Better models of the components enables more efficient and accurate prediction of harmonics generated in the traction system. The aim of the thesis has been to improve the existing model of the traction system, with focus on the Line Converter Module (LCM). The LCM is one of the sources of harmonics in the system. The existing model does not have a line converter controller implemented. Therefore, the main part of the thesis work has been to integrate a controller into the model. The controller has been implemented in the program Simulink, while the rest of the traction system is developed in the Simulink Toolbox Piecewise Linear Electrical Circuit Simulation (PLECS). The focus of the work has been to study how the controller affects the harmonics in the system. In the thesis work harmonics up to 1000 Hz have been analysed. The results from the simulations show that the controller introduces harmonics into the system, in particular the third order harmonic prevails. In order to verify and validate the performance of the developed model, the simulation results have been compared with measurements from a Real-Time Simulation environment (RTS). The RTS utilizes the hardware of the control systems but simulates the rest of the traction system. The simulation results from the developed model show quite good agreement with the RTS measurements. However, it is important to later verify the model with real measurements from a vehicle, when such measurements become available. A main conclusion of the work is that the controller affects harmonics under 1000 Hz in the system and should be included in the model of the traction system in order to accurately predict the EMC disturbances.

Full textAbstract:
Pat Tillman—an Arizona Cardinals player who sacrificed everything to serve his country but died in Afghanistan—was initially touted as a true American hero who was killed by enemy fire. In reality, however, the Tillman narrative was based on nothing but military propaganda. This research focused on how mainstream U.S. newspapers used news frames, overall story tone, and news sources before and after the official acknowledgement of the true cause of Tillman's death as fratricide. As hypothesized from C. Wright Mills' "lesser institutions," Antonio Gramsci's hegemony, and Edward S. Herman and Noam Chomsky's propaganda model, the newspapers generally decreased both direct and indirect references to news frames involving "lesser institutions" (e.g., NFL, Arizona State University) and ideological values (e.g., heroism, patriotism) after the revelation, but they were not critical of the Iraq/Afghanistan wars or the Bush administration at all. In addition, they increased their dependence on official sources and decreased family and friend sources after his cause of death was changed. The results as a whole indicate that in the Tillman saga, the revelation of his true cause of death introduced a significant disruption to the propaganda information system, causing news frames to decrease, but the third filter of the propaganda model—reliance on official sources—was strong enough to overcome that disruptive event and continue to protect the power elite.

Full textAbstract:
Osteoporotic fractures are a major and increasing clinical and public health concern internationally. Identification of individuals at high risk for fragility fractures may enable us to target preventive interventions more effectively. In this thesis, I aimed to evaluate novel risk factors for osteoporosis and develop a fracture risk assessment model among the middle-aged and older people. I used data from the European Prospective Investigation into Cancer (EPIC)-Norfolk study, which is a large population-based prospective study started in 1993. About 25,000 men and women were assessed at baseline and about 15,000 of them returned for a second examination 4 years later. All participants are followed up to the present for clinical events including fractures. My work is in two parts. For the first part, I examined the risk of fracture associated with some novel or less well studied risk factors. These risk factors included change in height over time, respiratory function, physical activity and body fat mass. We found that men and women with annual height loss >0.5 cm are at increased risk of hip and any fracture (relative risk=1.9 (95% CI 1.3-2.7) per cm/year height loss). One litre lower forced expiratory volume in 1 second (FEV1) was associated with a 2-fold risk of hip fracture in men and women. We also observed a non-linear association, independent of body mass index, between increasing body fat mass and lower fracture risk in women but not in men. I performed a systematic review and meta-analysis of studies evaluating the association between physical activity and hip fractures. Using a new validated questionnaire in EPIC-Norfolk, we observed varying relationships between physical activity in different domains of life and fracture risk in men and women. For the second part of the thesis, I developed a biostatistical model to calculate 10-year risk of developing a fracture among EPIC-Norfolk study participants. This model incorporates clinical and radiological assessments known to be associated with fractures and can be extended to other risk factors assessed in other prospective cohorts. This helps clinicians to achieve a better estimate of the prospective risk of fracture in their patients. I applied this model to compare the predictive value of two different clinical assessment methods for osteoporosis, namely dual-energy X-ray absorptiometry (DXA) and quantitative ultrasound (QUS). We found that that the predictive power of QUS is comparable to, and independent of, predictive power of DXA. In summary, my studies have added to our knowledge about some novel and easy-to-use risk factors of osteoporosis and proposed a practical method to merge and utilise data from different risk factors for estimation of fracture risk in individuals.

Full textAbstract:
We obtained four pointings of over 100 ks each of the well-studied Wolf-Rayet star WR 6 with the XMM-Newton satellite. With a first paper emphasizing the results of spectral analysis, this follow-up highlights the X-ray variability clearly detected in all four pointings. However, phased light curves fail to confirm obvious cyclic behavior on the well-established 3.766 d period widely found at longer wavelengths. The data are of such quality that we were able to conduct a search for "event clustering" in the arrival times of X-ray photons. However, we fail to detect any such clustering. One possibility is that X-rays are generated in a stationary shock structure. In this context we favor a co-rotating interaction region (CIR) and present a phenomenological model for X-rays from a CIR structure. We show that a CIR has the potential to account simultaneously for the X-ray variability and constraints provided by the spectral analysis. Ultimately, the viability of the CIR model will require both intermittent long-term X-ray monitoring of WR 6 and better physical models of CIR X-ray production at large radii in stellar winds.

Full textAbstract:
The multi-branch diversity combining technique has been widely used in wireless communications systems to overcome the adverse effect of multipath fading. The three most popular diversity combining schemes are selection combining (SC), equal gain combining (EGC), and maximal ratio combining (MRC). In the performance analysis of multi-branch diversity combining, the asymptotic technique is an attractive approach to obtain compact and accurate error rate and outage probability in large signal-to-noise ratio (SNR) regions. Asymptotic performance can be obtained either in the time domain by finding the probability density function (PDF) of the instantaneous output SNR, or in the frequency domain by finding the moment generating function (MGF) of the square root of the instantaneous output SNR. In this thesis, the PDF of the instantaneous SNR at the output of selection combiner and the MGF of the square root of the instantaneous SNR at the output of equal gain combiner over arbitrarily correlated Nakagami-m fading channels are derived and used to obtain asymptotic error rate and outage probability expressions of SC and EGC, respectively. These expressions provide accurate and rapid estimation of error rates and outage probabilities. The accuracy of our analytical results is verified by computer simulation. More importantly, our analytical results provide physical insights into the transmission behavior of EGC and SC over arbitrarily correlated Nakagami-m fading channels. For instance, it is shown that the asymptotic error rates over correlated branches can be obtained by scaling the asymptotic error rates over independent branches with the factor which is the determinant of matrix M to the power m, where the elements of M are the square root of corresponding elements in the branch power covariance correlation matrix R. A similar relationship can also be found for the outage probabilities.

Tesis para optar al grado de Doctor en Ciencias de la Ingeniería, Mención Modelación Matemática<br>La investigación de esta tesis es presentada en seis capítulos, desde el Capítulo 2 al Capítulo 7.
El capítulo 2 proporciona una demostración directa de una caracterización reciente
de convexidad dada en el marco de los espacios de Banach en [J. Saint Raymond, J. Convexo no lineal
Anal., 14 (2013), pp. 253-262]. Estos resultados también extienden esta caracterización a espacios localmente convexos
bajo condiciones más débiles y se basa en la definición de una función epi-puntada.
El Capítulo 3 proporciona una extensión del Teorema Br{\o}ndsted-Rockafellar, y algunas de sus importantes consecuencias, a las funciones convexas semicontinuas inferiores definidas en espacios localmente convexos. Este resulado es demostrado usando un nuevo enfoque basado en un principio variacional simple, que también permite recuperar los resultados clásicos de una manera natural.
El Capítulo 4 continúa el estudio de la epi-puntadas no convexas, bajo una definición general de subdiferencial. Este trabajo proporciona una generalización del teorema del valor medio de Zagrodny. Posteriormente este resultado es aplicado a los problemas relacionados con la integración de subdiferenciales y caracterización de la convexidad en términos de la monotonicidad del subdiferencial.
El Capítulo 5 proporciona una fórmula general para $\epsilon$-subdiferencial de una función integral convexa en términos de $\epsilon$-subdiferenciales de la funcion integrante. Bajo condiciones de calificación, esta fórmula recupera los resultados clásicos en la literatura. Además, este trabajo investiga caracterizaciones del subdiferencial en términos de selecciones medibles que convergen al punto de interés.
El Capítulo 6 proporciona fórmulas secuenciales para subdiferenciales bornológicos de un funcional integral no convexo. También son presentadas fórmulas exactas para el subiferencial Limiting/Mordukhovich, el subdiferencial Geometrico de Ioffe y el subdiferencial de Clarke-Rockafellar.
El Capítulo 7 proporciona fórmulas para el subdiferencial de funciones de probabilidad bajo distribuciones Gaussianas. En este trabajo la variables de decisión esta tomada en un espacio infinito dimensional. Estas fórmulas se basan en la descomposición esférico-radial de vectores aleatorios Gaussianos.<br>CONICYT-PCHA/doctorado Nacional / 2014-21140621 y CMM - Conicyt PIA AFB170001

The theses compares analytical methods according to current norms used in the Czech Republic to the methods based on the principle according to US EPA. A new device the automatic photometer Aquakem 250 makes use of the US EPA methods. Prior to its laboratory use in the Institute of Public Health in the town of Ostrava the photometer had to be validated. For the comparsion of the analytical methods ion chromatographic, isotachophoresis, spectrophotometric,titrimetric methods were used. The validation process, which was documented (in validation protocols), was time consuming and technically challenging. It was confirmed that the new Aquakem 250 analyzer provides result that are verified by methods which are in accordance with norms applicable in the Czech Republic. After a successful completion of validation and obtained accreditation the new automatic analyzer was put into regular operation in the chemically laboratory.

Full textAbstract:
<p> Paul Tillich’s analysis of Genesis 2 and 3 in his Systematic Theology Volume 2 arguably amounts to a theory of evil A puzzling aspect of his conceptual framework, however, is that Adam and Eve do not exemplify his explanation of evil so much as imply it. Although Adam and Eve may indulge in a taste of unbelief, hubris, and concupiscence, the Genesis text offers no evidence that this taste transforms them into the compulsively exploitative, egocentric tyrants that Tillich describes. However, Tillich’s analysis works exceptionally well when applied to the older Gilgamesh narrative. Applying the Tillichian dynamics of hubris and concupiscence helps to make sense of Gilgamesh’s destructive appetites for power and fame. It also sheds light on the significance of the numerous parallels between the two stories. When we read Gilgamesh through this Tillichian lens, and then read Genesis 2 and 3 with Gilgamesh in mind, new interpretive possibilities emerge from the stories’ parallels elements. The character Gilgamesh’s original sin is hubris as Tillich defines it: denial of finitude. Existentialist depth psychologist Ernest Becker agrees with Tillich’s observation that finitude is man’s core fear, and as such is the catalyst of man’s most rapacious predation upon his fellow humans. Becker compliments and extends Tillich’s framework; and reading Gilgamesh with Tillich’s conceptual framework clarifies both the Gilgamesh epic and the Tillichian framework itself. Moreover, if we then re-read the Eden myth with Gilgamesh in mind as the exemplar of that framework, both clarity and new interpretive possibilities for understanding the Eden myth also emerge. In the following, we will consider the concepts which constitute Tillich’s interpretive framework, as well what Ernest Becker might add to it. Then we will apply these to the Gilgamesh. Finally, we will return to Genesis 2 and 3 with this Tillichian reading of Gilgamesh in mind.</p>

Full textAbstract:
The purpose of this study is to observe childrens adaptation to an electropalatographic (EPG) sensor. Sound recordings of six children between the ages of 7;0 and 9;11 sampled at 30-minute intervals over a two-hour period of wearing an EPG sensor were perceptually evaluated to quantify the children's adaptation over time. Twenty native speakers of American English evaluated the pronunciation of a series of words with embedded stops and fricatives produced with and without an EPG sensor in place. When collapsed over speaker and stimulus type, listener ratings decreased significantly after inserting the EPG sensor. Ratings then increased significantly after the sensor was in place for 30 minutes, and again after 60 minutes. No significant improvement in pronunciation was noted between the 60- and 120-minute test intervals, and adaptation did not reach preplacement levels until the sensor was removed. Mixed results were found in how speakers adapted across the different stimulus types. Adaptation was most consistent across speakers for the conversation conditions, but occurred most rapidly for /s/ and /k/. Speakers showed the best overall adaptation for the phoneme /t/ by the end of testing. These results are similar to several adaptation studies with adults, and the two studies with children. Results from this study will help speech pathologists effectively use EPG technology to help children accurately pronounce speech sounds, and to generalize these pronunciations to their normal speech.

Full textAbstract:
A study to optimise an IgG based immunosensor is presented, that has been carried out by absorbing monolayers to a gold transducer surface at varying immersion times and temperatures. The theory and kinetics of monolayer adsorption are analysed and discussed. Existing mathematical models are reviewed and experimentally researched, to highlight gaps in knowledge that would facilitate high quality, cost effective immunosensor production. The creation of two mathematical models to predict monolayer adsorption kinetics and optimal immersion times are discussed. Details are provided of how the new mathematical models may be advanced, and how the production of immunosensors may be further improved. The first novel mathematical model (PTCS) has been created to model the presence of two sequentially forming structures on the surface of a substrate. It gives an insight into the percentages of each structure on the surface, along with the actual adsorption process. This model provides a good fit to all applicable experimental data and has allowed the deduction of optimum immersion times. The second novel model (PIF) provides a greater insight than existing models into the individual contributions to surface coverage by both random and island growth. This allows an insight into how the monolayer surface is covered, which is critical to determine the optimum conditions for adsorption. This model also provides a good fit to the isotherm data it has been applied to. To provide a thorough understanding of the bulk properties of monolayer formation over the gold transducer, and how these properties vary with immersion time and temperature, various measurement techniques have been employed. Electrochemical Impedance Spectroscopy (EIS) has been the principle measurement technique used to measure the bulk properties, but confirmation studies have also been carried out including, Contact angle measurements, FTIR microscopy with BSA molecular labels, Fluorescence microscopy for small adsorbed molecules and AFM for layers assembled from macromolecules. The data generated from the different techniques show consistency with the arguments discussed in each instance. Two different IgG adsorption processes have been compared. These include direct IgG addition and a multilayered streptavidin-based process. The results indicate that IgG molecules adsorbed via the streptavidin based multilayer process are more vertically orientated and have a higher packing density of IgG molecules. Keywords: Self Assembled Monolayer, impedance-based immunoassay, Streptavidin, biotinylated IgG, mathematical adsorption modelling.

Full textAbstract:
For the last ten years, DVD-R media have played an important role in the storage of large amounts of digital data throughout the world. During this time it was assumed that the DVD-R was as long-lasting and stable as its predecessor, the CD-R. Several reports have surfaced over the last few years questioning the DVD-R's ability to maintain many of its claims regarding archival quality life spans. These reports have shown a wide range of longevity between the different brands. While some DVD-Rs may last a while, others may result in an early and unexpected failure. Compounding this problem is the lack of information available for consumers to know the quality of the media they own. While the industry works on devising a standard for labeling the quality of future media, it is currently up to the consumer to pay close attention to their own DVD-R archives and work diligently to prevent data loss. This research shows that through accelerated aging and the use of logistic regression analysis on data collected through periodic monitoring of disc read-back errors it is possible to accurately predict unrecoverable failures in the test discs. This study analyzed various measurements of PIE errors, PIE8 Sum errors, POF errors and jitter data from three areas of the disc: the whole disc, the region of the disc where it first failed as well as the last half of the disc. From this data five unique predictive equations were produced, each with the ability to predict disc failure. In conclusion, the relative value of these equations for end-of-life predictions is discussed.
