Abstract The purpose of this thesis is to examine the electrical properties of pacemaker leads by measurements and theoretical analysis. If time allows, recommendations on how to construct a simple circuit model to explain the phenomenon will be given based on the electrical properties obtained from measurements performed during the work of this thesis. Additional information on pacemaker lead heating during impact of magnet in X-ray (MRI) will be presented if time allows. Significant electrical properties of pacemaker leads are compiled in this thesis.   ANALYSIS OF CIRCUIT MODEL The purpose of this model is to create an equivalent electronic circuit model that describes a pacemaker lead electrical property. The model is divided into three different sections: proximal part, the homogeneous coil part and the distal end.  The model will include series inductance, parallel capacitance, series resistance, lossless admittance and winding capacitance between each loop for the homogeneous coil part, additionally the impedance of the proximal and distal part will be included.

Hollywood: The Sequel provides an historical account of film sequelization and its importance to the domestic entertainment industry from a marketing standpoint. Based on an extensive literature revenue, it was conjectured that the ratio of domestic sequel‐generated revenue to overall domestic revenue from the 1950s‐2000s would follow a classic diffusion pattern. Utilizing historical trade data from Variety magazine, Excel and SPSS databases were developed to determine the percentage of sequel‐generated domestic box office revenue from 1954‐2006, relative to overall revenue. The formal hypothesis was that from the 1950s‐2000s the adoption of sequels in the 70‐highest‐performing films follows a diffusion s‐curve. The goodness‐of‐fit of the historical dataset (N=3,710) with the s‐curve estimation‐algorithm was measured against the goodness‐of‐fit of other widely utilized curve estimation‐algorithms and the linear‐regression model— the curve estimation algorithms utilized included logarithmic, inverse, quadratic, cubic, compound, power, growth, exponential, and logistic. Several content‐analysis intensive research questions were asked and explored in the dissertation including the following: Do Epstein‐scores for sequels in the 70‐highest‐performing titles per year increase from the 1950s‐2000s? In the event Epstein‐scores for sequels in the 70‐highestperforming titles per year increase from the 1950s‐2000s, what growth model provides the best fit with the historical data? What is the growth rate associated with minority representation in lead roles in sequels from the 1950s‐2000s? How have sequels with minority leads fared in terms of box office performance, versus sequels overall from the 1950s‐2000s? What is the growth rate associated with female representation in lead roles in sequels from the 1950s‐2000s? And, finally, how have sequels with female leads fared in terms of box office performance, versus sequels overall from the 1950s‐2000s? / text

This thesis aims to determine whether RF pulsed exposures from mobile phones can influence nervous function within the human brain and heart. In order to address this objective, a robust double-blind study to investigate mobile phone exposures on nervous response has been undertaken by means of analysis of electrophysiological test measures of brain wave activity and heart responses. Generally, test measurements of the electroencephalogram (EEG), the electrocardiogram (ECG), and the pulse plethysmogram (PPG) (for indications of blood pressure response) have been undertaken whilst participants are exposed and sham exposed to various GSM mobile phone radiofrequency and low-frequency protocols. In initial work, both standby and full-power mode GSM exposures have been investigated (Chapter 3 - EEG investigated only), while pulsed 900 MHz and 1800 MHz continuous wave exposures have been investigated in the final experimental work involving 100 test participants (Ch apter 8 - EEG, ECG, and PPG measures are investigated). Four predominant outcomes are determined from the final experimental work conducted. These main outcomes specifically include: 1. A new 'characteristic' finding in the EEG alpha band (8-13 Hz) as due to 900 MHz exposures is observed from almost all recording sites, over both brain hemispheres. Notably, this response only appears at 900 MHz, though is not observable for the 1800 MHz exposure; 2. An EEG effect due to both pulsed 900 MHz and 1800 MHz exposures notably appearing at 16 Hz is a new critical finding and is observed across both hemispheres. Most importantly, at this beta rhythm only a decreasing tendency in EEG power can be noted for the 900 MHz exposure tested but only an increasing tendency in EEG power may be noted at 1800 MHz, suggesting that the direction of the effect in EEG power may be dependent on the RF component; 3. Effects at 900 MHz on the contralateral side to exposure at central, temporal, and parietal sites appear to indicate a common median difference response between sham and exposure EEG spectral power density, which does not appear on the ipsilateral side to exposure; 4. As consistent with most previously published research, 900 MHz or 1800 MHz exposures pulsed at 217 Hz do not appear to alter heart rate, heart rate variability (HRV), or blood pressure variability (BPV). To reduce confounding factors and errors in experimental results, several novel approaches were developed as described (Chapters 4 - 8). These approaches include the development and testing of an experimental handset to support multiple mobile phone signals, a comparative analysis of 900 MHz and 1800 MHz exposures (near the health protection limits) on the same group of participants in simultaneous experiments, development of a statistical analysis approach to EEG that addresses both type 1 and type 11 errors at high resolution, and quantification of potential effects of EEG recording leads on SAR and electric field distribution (at both 900 MHz and 1800 MHz) inside a SAM phantom and realistic computational head model. Outcomes of this research address forefront international health concerns regarding almost 2-billion mobile phone users worldwide.

A method was proposed for the fabrication of air-gaps embedded in dielectric layers using thermally decomposable sacrificial polymers. The research had two main objectives: (1) the development and characterization of air-gap fabrication for use in a wide spectrum of applications; and (2) the integration of air-gaps into a specific application: air-gaps in an integrated circuit compliant wafer level packaging technology, Sea of Leads. Polynorbornene and polycarbonate sacrificial materials were used to form air-gaps at temperatures of 200, 300, and 400oC. Fabrication results of air-gaps encapsulated by both inorganic and organic dielectric materials indicated that the thermal and mechanical properties of the dielectric materials at the decomposition temperature of the sacrificial material resulted in success or failure of the process. Multi-layered encapsulating materials enabled the use of a dielectric material which does not successfully form air-gaps on its own. Thermal decomposition of the sacrificial materials with alteration in the polymer chemistry was studied. Polynorbornene containing 90 mol% butyl and 10 mol% triethoxysilyl side groups was selected as an optimum 400oC decomposition temperature material. The decomposition of this polynobornene composition in an open nitrogen atmosphere was contrasted to decomposition of the polynorbornene while completely encapsulated in a dielectric material. Thermogravimetric analysis and examination of residual surfaces following the decomposition, combined with comparison of the overall kinetic parameters of the decomposition reaction, indicated differences in the two overall processes. The design concept of Sea of Leads three-dimensionally compliant packaging technology with embedded air-gaps is presented. The critical issues resulting from the addition of air-gaps into the process are the compatibility of materials, lithography on topographical features, and yield and uniformity. Factors influencing the z-axis mechanical performance of the air-gap were determined to be the air-gap shape and size, the encapsulating material dielectric properties and thickness, and the decomposition conditions. Model calculations combined with the known limitations of fabrication provided a design space for maximum out-of-plane mechanical movement and compliance of the air-gaps. The results demonstrated that the incorporation of an embedded air-gap in Sea of Leads technology can achieve the necessary z-axis compliance goals for future applications.

Precise specification of the architecture and design of software is a good practice. Such specifications contain a lot of information about the software that can potentially be exploited by tools, to reduce redundancy in software writing by automating routine tasks, as well as giving valuable feedback on the software. We first broadly classify such tools based on their application, and look at some of the issues involved in writing them. Most of these tools are built using conventional programming languages that do not provide primitives that are routinely required by such tools. We identify some patterns that are seen while writing such tools and abstract them out into a language specially designed for the purpose. Our effort is a language called LEADS, where we attempt to make writing such tools a lot easier, modular, organized and portable. LEADS is based on the Pattern-Action approach, where one specifies the pattern of information of interest and the actions to be taken when it is found. The patterns are specified using a custom declarative language that is enriched with special primitives for routinely occurring constructs. LEADS also decouples itself from the specification environments and formats thereby ensuring wide applicability. This enables LEADS scripts to be ported across design environments with minimal effort.
