Full textAbstract:
The impact of animal disease on human societies has been highly publicised recently, both as a consequence of diseases that have spread amongst animal populations (e.g. foot and mouth), as well as those that have 'jumped' from animal to human populations (e.g. HIV, bird flu and BSE). Non-disease-related pathologies can also provide much information about human-animal interactions, such as the use of animals for traction or riding. While the human, social and economic effect of such conditions is profound, the study of their impact on past human populations has been widely neglected. This is partly due to the inconsistent manner in which incidences of animal disease (palaeopathology) have been collected, recorded and interpreted which, together with the typically low incidence of specimens per site, has precluded any detailed studies of regional or temporal trends. The aim of this project was to improve the study of animal palaeopathology in order to attain a better appreciation of the potential for such research to resolve archaeological questions. This was to be achieved by designing, developing and implementing a methodology to overcome these problems and enable the past impact of animal disease to be better understood.;The primary objectives were to: Design and develop a generic methodology to facilitate the consistent recognition, recording and description of animal palaeopathological data; implement the methodology within a database system; and apply and critically evaluate the methodology, using assemblages from the Roman legionary fort at Alchester and the Roman town of Colchester, and demonstrate the benefits of adopting a systematic approach to recording animal palaeopathology.

In addition, storage has limitation of capacity. So, we need to research about a data recording structure within a limited amount of memory. In this paper, we propose a new data recording structure through a condition necessary for efficient use of memory. The proposed structure has an equivalent function as other recording systems. But, it uses less memory than the other equivalent recording structures.

The high data rates typical in networked FTI systems put increased demands on the Network-Recorder to support ever faster read and write rates. However, thanks to the developments in CompactFlash and SATA technologies, such recording rates are achievable in the Network-Recorder. This paper discusses several ways in which the recorder can be optimized to improve the memory capacity usage, writing speed and relevance of the recorded data.

Full textAbstract:
Presented here are micromagnetic simulations to investigate alternative magnetic recording technologies including bit patterned media and domain wall storage. I have used a finite element/boundary element method to investigate the dynamics of the write process in magnetic recording systems; and a nudged elastic band method is used to calculate the thermal stability of written bits. Microwave assisted magnetization reversal of single phase media and exchange spring media is investigated. A reduction of the switching field by about a factor of two can be found in both single phase and exchange spring media when the microwave field reaches an amplitude that is 12 percent of the remanent coercivity without microwave assist. Furthermore, layer-selective writing of two-layer bitpatterned media is demonstrated by employing microwave assist technique. Selectivity is achieved by controlling the frequency of an oscillating magnetic field in the GHz range, applied in addition to the head field. Generation of the microwave field by means of a wire next to the tip of a single pole head is proposed. Optimization of writing heads is performed using micromagnetics and surrogate optimization. The shape of the pole tip is optimized for bit patterned, exchange spring recording media. I computed the write error rate and the adjacent track erasure for different maximum anisotropy in the multilayer, graded media. The results show a linear trade off between the error rate and the number of passes. Finally I have calculated magneto static fields from transverse and vortex magnetic domain walls in a planar Ni81Fe19 nanowire. These calculations indicate the required sensitivity of a nearby sensor for detecting either a domain wall of any type or being able to distinguish the domain wall character.

Full textAbstract:
This thesis studies the development of the British recording studio from the mid-1960s to the early-1990s. Although there are now a growing number of academic studies of popular music they have, so far, largely failed to study the evolving process by which artists were able to reproduce their music for mass distribution. Consequently, this dissertation investigates the image portrayed of the studio and its utilisation and representation by a combination of human, technological and locational factors. The first part of the thesis constructs an overview of the recording studio industry, as based on contemporary trade journals, in order to produce a traditional historical narrative, so far absent from music’s historiography, which provides the framework in which to place more detailed research. The prominence given by the industry to the ‘progress of technology’ is then compared to the public perception of the recording studio, as shown by the extent and content of its inclusion in the popular culture media of the period, both print and film based. How far the process of producing recorded music managed to permeate through the presentation of a music industry that was becoming increasingly reliant on the image and personality of the artists themselves is then analysed. The second part of the thesis is based on Latour’s concept of actor-networks and deconstructs the recording studio into three main components; technology, architecture and the human element within it. Using one particular studio (Strawberry Recording Studios in Stockport) as being representative of the increasing proportion of small independents in the industry, the further deconstruction of these three components into their constitutional networks, provides the key theme of the dissertation. Consequently, studio technology can be viewed not simply in terms of functional machinery in the studio setting (of Latourian ‘black boxes’) but more as a confusing and intrusive element that was developed, shaped and created by the requirements of those in the studio. And, whilst contemporary society has always elevated the status of the performer in the music industry, the human element in the studio can also be shown to comprise the industrial and social interaction between a wide range of support staff, whose roles and importance altered over time, and the artists themselves. Finally, studio buildings were not just backdrops to the work taking place in them but were seen to extend their boundaries and influence beyond their immediate location through their architecture, interior design and geography. In other words, the recording studio might be seen as the combination of a number of fluctuating networks rather than just as a passive element in the production of recorded music. As a result of the content of the subject being studied, this thesis utilises a number of sources that, in Samuel’s terminology, moves the study away from a ‘fetishization’ of the traditional historical archive towards those of ‘unofficial learning’. Given the immediacy of the period being studied, the personal accounts of those involved in the studio, mainly through the use of oral history, form a major part of the research material.

<p>In the first part of this work, the influence of hydrogen on the structural and magnetic properties of Fe/V(001) superlattices was studied. The local structure of the vanadium-hydride layers was determined by extended x-ray absorption fine structure (EXAFS) measurements. The magnetic ordering in a weakly coupled Fe/V(001) superlattice was investigated using the magneto-optical Kerr effect (MOKE). The interlayer exchange coupling is weakened upon alloying with hydrogen and a phase with short-range magnetic order was observed.</p><p>The second part is concerned with first-principles calculations of magnetic materials, with a focus on magnetic recording applications. The uniaxial magnetic anisotropy energy (MAE) of Fe, Co, and Ni was calculated for tetragonal and trigonal structures. Based on an analysis of the electronic states of tetragonal Fe and Co at the center of the Brillouin zone, tetragonal Fe-Co alloys were proposed as a material that combines a large uniaxial MAE with a large saturation magnetization. This was confirmed by experimental studies on (Fe,Co)/Pt superlattices. The large uniaxial MAE of L1<sub>0</sub> FePt is caused by the large spin-orbit interaction on the Pt sites in connection with a strong hybridization between Fe and Pt. Furthermore, it was shown that the uniaxial MAE can be increased by alloying the Fe sublattice with Mn. The combination of the high-moment rare-earth (RE) metals with the high-<i>T</i><sub>C</sub> 3<i>d</i> transition metals in RE/Cr/Fe multilayers (RE = Gd, Tb, Dy) gives rise to a strong ferromagnetic effective exchange interaction between the Fe layers and the RE layer. The MAE of hcp Gd was found to have two principal contributions, namely the dipole interaction of the large localized 4<i>f</i> spins and the band electron magnetic anisotropy due to the spin-orbit interaction. The peculiar temperature dependence of the easy axis of magnetization was reproduced on a qualitative level.</p>

Full textAbstract:
The Fourier method is used to provide new analytic solutions for idealized mathematical models of double-element shielded magnetoresistive (MR) recording heads. The general two-dimensional model allows analysis of various recording head configurations; a single pole head, a ring head, a dual stripe head and a differential head. The analysis accommodates both longitudinal recording (with no soft magnetic underlayer present) and perpendicular recording (in the presence of a soft underlayer). Typical field, spectral response function and output voltage pulse plots for double-element MR heads are given and compared to published, approximate solutions. The integrals arising in the determination of the Fourier series coefficients, magnetic potential and magnetic field components are expressed either as rapidly convergent infinite series or in terms of special functions to provide a more efficient means of evaluation than numerical integration. It is shown that, in many situations, it is only necessary to take the first Fourier coefficient in the calculation of output voltage pulse shapes in order to achieve sufficiently accurate results. Bi-variate regression techniques are used to provide a convenient method to approximate the first Fourier series coefficient for a broad range of typical head dimensions. The thesis goes on to examine high speed switching behaviour in two classes of recording media by considering two different particle orientation distributions; 2D random media - intended to simulate a modern thin film rigid disk, and 3D oriented media- simulating a single domain particulate tape media. The gyromagnetic switching constant of a medium is calculated directly from the Landau - Lifshitz - Gilbert (L-L-G) equation of motion, which is solved numerically. The switching constants produced are discussed and compared with published experimental values for different media.

ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California<br>Traditionally, acquired instrumentation data on a non-destructive test article is recorded to a nonvolatile memory recorder. The data acquisition system usually samples and formats its inputs before transmitting the data to the recorder (also known in this paper as a data sink) via a PCM serial data stream (i.e., clock and data). In a network-based data acquisition architecture, the inclusion of an IP-based recorder adds a new dimension to the data acquisition process. Any IP network inherently allows for the bi-directional exchange of data. In this environment, the IPbased recorder can be treated as both a data sink for parameter recording and a data source for parameter extraction, data rate statistics, and recorder status reporting. The network model recasts the data recorder’s function as a file server to which multiple clients could be simultaneously requesting services. Those clients that represent the data acquisition nodes are requesting storage of their acquired parameters. Clients, such as transmitters or test engineers, are requesting access to archived data or status information for further processing. This paper presents the advantages of using an IP-based recorder in a network-based data acquisition system. The availability of an IP interface along with the intelligence built into the recorder expands its capabilities beyond that of a conventional PCM recorder. These capabilities include real-time health monitoring, support for the Simple Network Management Protocol (SNMP), data mining, reporting of real-time performance and network statistics.

International Telemetering Conference Proceedings / October 28-31, 1985 / Riviera Hotel, Las Vegas, Nevada<br>A novel source of noise is identified and described in this study. If a continuous recording medium is less than perfectly uniform, a given quantity may be recorded differently at different locations in the medium. Inadvertent “encoding” occurs, embedding noise in the signal. Symmetrical sideband noise power results from amplitude and phase modulation of the signal stream by the nonuniform recording medium. “Write noise”, so-called because writing is required, is correlated in amplitude with signal amplitude, and its mean frequency is the signal frequency. It is the dominant noise source for the current generation of recorders and tapes; its power spectrum is almost the same as the power spectrum of the signal. The ratio of standard deviation to mean value of the signal envelope when recording cw signals is an absolute measure of tape quality independent of record level, tape speed, and track width, and establishes an available signal-to-noise ratio which cannot be exceeded. It is assumed that the recorder output has a normal amplitude distribution about its mean value. Theory is confirmed by experiment, within experimental error, for cw and digital recording.

This paper is about my investigation of early bluegrass recording techniques and the processes they used. After doing some extensive research, and compiling a database of black and white photographs from the time period, I felt I had enough information to assemble a team to try and produce the sounds, tonal qualities, and energy those recordings have. So John Kornhauser, Joshua Gooding, Hunter Berry, Sarah Griffin, along with myself, went to BigTone studios and tracked for two four hour sessions. BigTone studios has all of the vintage microphones, tape recorders, echo chambers, and out board equipment I need to replicate the same signal chain that was used on the early recordings. After the recording process, I mixed and mastered the songs to match the early recordings as closely as possible. We also recorded one song at ETSU’s studio that was all digital with new equipment to show the differences in the sound of analog versus digital recording. I have included both so that you can listen to each and determine for yourself if there is an audible difference, and if that difference is worth pursuing.

Full textAbstract:
Direct overwrite in magneto-optical recording is necessary to overcome the latency incurred by conventional erase before write recording on magneto-optical disks. In this work we theoretically analyze the thermomagnetic recording process on optical disks using a domain wall motion model. The wall motion model developed in this work can be used to examine overwrite schemes on both bilayer and single layer disks, that either rotate beneath an optical head or remain stationary. The model is directly compared with experiment for a GdTbFe direct overwrite sample, and is shown to produce results that are in agreement with experimental observations. We show that variations in the domain wall saturation velocity can mean the difference between writing or erasing a bit on the disk, and hence is a critical parameter in the recording process. We also show that direct overwrite by means of interior nucleation is highly unlikely. Rather, we show that the recording process involves a dynamic balance between those pressures which act to move the domain wall and those which act to freeze it into place. Finally we analyze the Nikon bilayer direct overwrite scheme, and then demonstrate an alternative bilayer overwrite scheme which avoids a major problem with the Nikon scheme.

Full textAbstract:
With highly demanding requirement in current emerging cloud storage and personal computers, hard disk drive recording with high stability and high volume has attached much attention in industry and academy. Recording media and recording head feasible for future high-density recording are both crucial to utilize magnetic recording with 1T bit/in2 recording density.
Recoding media with FePt for high density and high stability was investigated in this thesis using FePt polymers with imprinting methods and FePt thin films with ion-beam bombardment technologies. The FePt polymers can be patterned using imprint at micro-and nano-scales. The micro-and nano-patterns could be retained on substrates after sintering at high temperatures. The high magnetic coercivity was proved with line and dot patterns at different scales.
Recording heads with Al2O3based magnetic tunneling junction sensors were also studied in thesis. The magnetic tunneling junction sensors were proved to work stable at different temperatures varying from -30oC to 100oC. The long time running test up to 100 hours also proved the stability of the magnetic tunneling junction sensors working in extreme temperatures.
Withstate-of-art patterning and depositing technologies, new ideas about using FePt polymer to work as magnetic recording media and using ion beam bombardments to tune the FePt magnetic properties were verified.

Research methods combine creative practice with participant observation through a comparative set of music production projects that compare recordings done in large-format recording studios with those done in DIY contexts, and with a hybrid approach combining both. The findings indicate a new recording paradigm in which DIY spaces have become a domesticated form of a once industrialised production process.

<p>In this paper different approaches for digital video recording in vehicles are examined, with weight on video quality. Different video compression algorithms were gone through and the conclusion was that inter-frame compression, like MPEG video delivers better video quality than intra-frame algorithms, for example Wavelet. The main drawback is that it is difficult to extract single frames, which leads to difficulties when for example backwards-playability is needed. To demonstrate how digital video recording can be done a demonstrator was built. Therefore, when the decision to use MPEG compression was made, a market research was done and a video grabber expansion card for PCs was bought. The report describes the hardware and software developments that had to be made to run the video recorder.</p><p>The result of the thesis was this report and a functioning recorder. The delivered video quality was fair and it was also remote controlled.</p>

Full textAbstract:
The study of a magnetic recording media dispersion has been carried out using hindered settling analysis, the purpose of which was to probe the equilibrium state structure in zero applied magnetic field. The system chosen for the main study was based on a commercial formulation of a y-Fe 203 suspension of 0.3 j.tm length acicular particles, with aspect ratio 5: 1, that was used to manufacture a back-up/archive tape. From the sedimentation analysis, a large fraction of fluid (- 86 % by volume of the settling unit) was estimated to be trapped within the clusters of particles that make-up the overall dispersion structure. Confidence in the result was given by correction of the classical hindered settling models to account for the trapped fluid. In this manner, the range of Steinour and Kozeny-Carman parameters evaluated reduced near to, or agreed with, the fundamental values found by the original authors on simple model systems that contained little to no trapped fluid. Near- Newtonian fluid measurements resulted in an equivalent Stokes particle diameter of - 6.7 Jim. A computer simulation of hindered settling has been developed, based on a laminae concept and the Kozeny-Carman equation, in order to complement the experimental investigation. The concentration profiles over columii height compared well with those obtained using a scanning column magnetometer to give an enhanced description of the hindered settling phenomena. This showed that the descending 'plug' of constant solids concentration falls down into, and is continually subsumed by, the rising layers of the lower compression region. The plug effectively contracts about its mid-point and the initial constant rate of fall is only maintained up to the point where the plug is destroyed. It was also found that the model only gave a reasonable comparison with experiment when the effective ratio of trapped fluid was large; giving further confidence in the trapped fluid estimate. The theory of the scanning column magnetometer technique has been developed beyond that already known. This resulted in good agreement between theory and experiment in characterising the main detection coil response, or 'form factor' and means that future design work will be enhanced. The effects of magnetic interaction in the magnetic media dispersion have been investigated by varying the magnetic y-Fe 203 content by dilution with cz-Fe 203 (produced from the same particles) whilst holding the total particle concentration constant. The resultant increase in sedimentation with magnetic interactions has been interpreted in terms of hindered settling theory as being due to the formation of clusters by magnetostatic attraction. Extension of the experiment should give a strong indication of the extent that magnetic particles trap fluid in comparison to their non-magnetic depletion flocculated precursor. This could be significant in the context of the drying stage of the magnetic recording media production process.

The primary aim of this project is getting a complete understanding of photography’s development process and looking into future, user-centered innovations. Digital evolution changed the rules of product design. Products became a part of a complex system, consisting of a variety of different touch-points which also constantly extend. Photography and cameras are changing. Mobile phones, wireless connections and sharing platforms have a big impact on photography. Everything is getting connected to each other, both people and devices. How will digital photography adapt to this new world? How will people change their perception of images? Is it possible to design a camera considering all other systems around it? While designing a highly technological device, how can user-perspective be included in the design process?

For a year and a spring semester, I have been in the works of a school music project. I set out to make a record of ten self-penned songs. Along the length of the project, I would discover musicians and recording artists. I notated my songs on a staff and recorded demos to assist players of drums, electric bass, French horn, and violin. I play guitar, percussion, synthesized instruments, and do all of the singing on Brown Study, the record's title. The technology used to create the songs include a Tascam 2488 (home digital recording device), computers, printers, cell phones and i-phones, amplifiers, microphones and headphones, and a drum machine. This is my first attempt at collaborating with other musicians. At the defense I will be presenting 4 songs: "Runaway," "Lonely Heart," "Topsy Turvy," and "Friendliest Advice." Each song has a particular history and story to tell containing influences and aesthetic philosophies.

Cookson, Richard David. "Transverse susceptibility studies of recording media." Thesis, University of Central Lancashire, 2002. http://clok.uclan.ac.uk/7714/.
Full textAbstract:
A highly sensitive transverse susceptometer has been developed for the investigation of magnetic recording media. The susceptometer was based on the design of Pareti and Turilli[4] with modifications to the solenoid and sensing coils. The modifications have resulted in an improvement in the signal to baseline ratio of a factor of 525, and a reduction in random noise. The increase in the sensitivity of the susceptometer allowed the investigation of Advanced Metal Particle (AMP) tapes and the measurement of the imaginary component of the transverse susceptibility (TS) proposed by Papusoi[5]. Also, a modification was developed which allowed the investigation of the non-linear TS, proposed by Chantrell et al[7]. The work reported for the latter two techniques was the first experimental demonstration of these measurements on magnetic recording media. Samples of Co-y-Fe203, Cr02, mixed y-Fe203 / Cr02 and AMP tapes were investigated, as were y- Fe201, Cr0 2 and AMP powders. The investigations suggested that the incoherent reversal mode was dominant in the systems containing Cr02, with coherent reversal dominant in the remaining systems. The anisotropy peaks measured using the non-linear IS were found to be less dependent on sample texture than those of the traditional linear measurement. In particular the anisotropy peaks of the non-linear TS for incoherently reversing systems appeared to be independent of texture and it was proposed that these were a direct measure of the anisotropy field distribution, although independent verification was not performed. The determination of magnetic coating thickness after Sollis and Bissell[6] was extended to allow the measurement of AMP tapes. A computer model was developed to investigate the error in the technique due to the particulate nature of the coating. The results of the model indicated that the error increased as coating thickness and volume packing fraction decreased. Correction factors were determined for MP3 and MP4 particle based systems. The detection of the imaginary component of TS and its close agreement with the theoretical predictions of Papusoi suggested that the dassification of TS as a 'stiffness' method of anisotropy field determination might be in error.

Full textAbstract:
With the rise of peer-to-peer software like Napster, many predicted that the digitalisation, sharing and dematerialisation of music would bring a radical transformation within the recording industry. This opened up a period of controversy and uncertainty in which competing visions were articulated of technology-induced change, markedly polarised between utopian and dystopian accounts with no clear view of ways forwards. A series of moves followed as various players sought to valorise music on the digital music networks, culminating in an emergence of successful streaming services. This thesis examines why there was a mismatch between initial predictions and what has actually happened in the market. It offers a detailed examination of the innovation processes through which digital technology was implemented and domesticated in the recording industry. This reveals a complex, contradictory and constantly evolving landscape in which the development of digital music distribution was far removed from the smooth development trajectories envisaged by those who saw these developments as following a simple trajectory shaped by technical or economic determinants. The research is based upon qualitative data analysis of fifty five interviews with a wide range of entrepreneurs and innovators, focusing on two successful innovation cases with different points of insertion within the digital recording industry; (1) Spotify: currently the world’s most popular digital music streaming service; and (2) INgrooves: an independent digital music distribution service provider whose system is also used by Universal Music Group. The thesis applies perspectives from the Social Shaping of Technology (“SST”) and its extension into Social Learning in Technological Innovation. It explores the widely dispersed processes of innovation through which the complex set of interactions amongst heterogeneous players who have conflicting interests and differing commitments involved in the digital music networks guided diverging choices in relation to particular market conditions and user requirements. The thesis makes three major contributions to understanding digital disruption in the recording industry. (1) In contrast to prevailing approaches which take P2P distribution as the single point of focus, the study investigates the multiplicity of actors and sites of innovation in the digital recording industry. It demonstrates that the dematerialisation of music did not lead to a simple, e.g. technologically-driven transformation of the industry. Instead a diverse array of realignments had to take place across the music sector to develop digital music valorisation networks. (2) By examining the detailed processes involved in the evolution of digital music services, it highlights the ways in which business models are shaped through a learning process of matching and finding constantly changing digital music users’ needs. Based on the observation that business models must be discovered in the course of making technologies work in the market, a new framework of ‘social shaping of business models’ is proposed in order to conceptualise business models as an emergent process in which firms refine their strategies in the light of emerging circumstances. (3) Drawing upon the concepts of musical networks (Leyshon 2001) and mediation (Hennion 1989), the thesis investigates the interaction of the diverse actors across the circuit of the recording business – production, distribution, valorisation, and consumption. The comprehensive analysis of the intricate interplay between innovation actors and their interactions in the economic, cultural, legal and institutional context highlights the need to develop a more sophisticated and nuanced understanding of the recording industry.

Thesis: S.M., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2018.<br>This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.<br>Cataloged from student-submitted PDF version of thesis.<br>Includes bibliographical references (pages 73-75).<br>To facilitate the usage of neural prosthesis, a sustainable recording method of cleaner neural signals is desired. While invasive neural electrodes can record neural activities with less noise than non-invasive methods and provide the ideal spatial-temporal resolution of the recorded signal, one major challenge of this invasive method is the potential tissue responses. The scar tissue that forms around the penetrating tip of the electrode may significantly degrade the signal quality in time, which causes the reading to be unreliable in the long-term. Solving this problem is key to enabling chronic usage of neural prosthetic systems. To tackle this challenge, previously Aalap Dighe has designed a reconfigurable neural probe using flexible polyimide material. The design used a spring-like structure to allow the electrode probe tip to move further inside the brain weeks after the initial implantation surgery. The latest generation of the devices, Gen 3, was tested both in vitro and in vivo using rodent models. In this thesis, the author continued the characterization of Gen 3 devices based on problems and observations occurred during the in vivo tests by Dighe, and proposed and tested an improved version of the device design, Gen 4. In particular, this thesis focused on solving the mechanical failure of some devices post-implantation and on reducing the instability of electrical properties of the electrodes. An improved structural mechanics simulation model of the design was used to characterize the mechanical properties of the devices. The simulation results were partially validated using benchtop load force tests, and were used to revise device design parameters for Gen 4. Experiments with Gen 4 devices showed that the new design met the design target well. Long-term in vitro impedance analysis of the electrodes was also performed using Gen 3 devices, which confirmed the observation of decreasing impedance over time in the previous in vivo tests. The results suggested delamination occurring between the polyimide layers, and the fabrication process was modified based on this hypothesis. Benchtop impedance tests of the new generation of devices confirmed that the delamination issue has been significantly improved.<br>by Boying Meng.<br>S.M.

Conventional chronic recording microelectrodes are made from metal or silicon. However, the large stiffness mismatch between the electrodes and brain tissue causes shear-induced inflammation, limiting long-term recording stability. The flexibility of a polypyrrole microwire has the potential to improve the chronic recording stability by minimizing the stiffness mismatch. This thesis shows the fabrication of conducting polymer electrodes and the stability of their impedance in physiological saline. The initial impedance was as low as 70 k[omega], but the electrode impedance increased by a factor of 10 when immersed in saline over 370 hours. This conducting polymer microwire electrode was implanted in a rodent brain and successfully used to record neuronal action potentials.<br>by Woong Jin Bae.<br>S.M.

Full textAbstract:
Current and potential next-generation magnetic recording technologies are based on the writing and reading of bits on a magnetic thin film with a granular microstructure, with grains of the magnetic material surrounded by an amorphous segregant. In order to realize the highest achievable data storage capabilities, there is a need for better control of the magnetic media microstructure, particularly in terms of minimizing grain size and grain boundary thickness distributions. In this work, a guided magnetic media growth is attempted by creating a pre-fabricated template with a specific material and morphology. The template is designed in such a way that, when magnetic media consisting of the magnetic alloy and segregant are sputtered, the sites on the template result in a controlled two-phase growth of magnetic media. The template is fabricated using self-assembling block copolymers, which can be used to fabricate nanostructures with a regular hexagonal lattice of spheres of one block in the other’s matrix. These are then used as etch-masks to fabricate the template. In this thesis, we describe the approach used to fabricate these templates and demonstrate the two-phase growth of magnetic recording media. In such an approach, the magnetic grain size is defined by the uniform pitch of the block copolymer pattern, resulting in a uniform microstructure with much better grain size distribution than can be obtained with conventional un-templated media growth. The templated growth technique is also a suitable additive technique for the fabrication of Bit Patterned Media, another potential next-generation technology wherein the magnetic bits are isolated patterned islands. Combining nanoimprint lithography with templated growth, we can generate a long range spatially ordered array of magnetic islands with no etching of the magnetic material.

This dissertation discusses the optical, magnetic and transport properties of magneto-optical recording media. The various custom-made and off-the-shelf instrumentation used in this study include: a Vibrating Sample Magnetometer (VSM), a modified polarization microscope, a polar Kerr effect loop tracer, a variable angle of incidence ellipsometer, and magnetoresistance/Hall effect/resistivity probes. Most of the samples studied were analyzed for determination of their composition and thickness by Rutherford Back Scattering (RPS) and X-Ray Fluorescence (XRF). The samples investigated were manufactured in several industrial and academic laboratories under different deposition conditions. The optical properties measured include Kerr rotation angle and ellipticity, Fresnel reflectivity coefficients, and calculation of the dielectric tensor. The magnetic properties include measurements of saturation magnetization, coercivity, anisotropy field, calculations of exchange energy parameters, domain wall, and anisotropy energy densities from experimental observations. The transport properties include measurements of magnetoresistance and Hall effect with three different geometries and calculation of the resistivity tensor. The modeling work consisted of modeling the optical path for various instruments, the current distribution in magnetic films, and the calculation of the demagnetizing energy using the fast Fourier transform technique.

International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, Nevada<br>This paper presents a general overview concerning McDonnell Douglas Helicopter Company's experience with the recording of Mil-Std-1553A/B MUX Bus traffic. There are several interesting aspects to this general overview. Included in this paper is a historical development review, a chronological development outline, general methodology involved, past and present application details, and speculation about future application possibilities. The historical background of the Company's 1553 MUX Bus recording efforts are traced - from our earliest involvement up to our current status. Several significant developments have led up to, and contributed to, the present level of experience with 1553 MUX Bus recording technology. A chronological list of important related events is also presented to complement this historical review (See Appendix A). Examples of McDonnell Douglas' applications of 1553 MUX bus recording are highlighted. Several examples are discussed from different related projects. A general overview is presented with regard to methods used by the Company to record 1553 MUX bus traffic. Several projects undertaken have involved new hardware/software development as a result of 1553 MUX bus recording efforts. Mention is also made of the Programmable MUX Bus Monitor - one of the most recent applications of this technology by McDonnell Douglas Helicopter Company. Rounding out this paper is some speculation about the future use considerations for this technology. The Company's experience with 1553 MUX bus recording was initially developed as a result of association with the Higher Harmonic Control aircraft and the AH-64 Apache Helicopter programs. However, once some of the basic techniques were established, and the technology was refined and improved, expansion into other unrelated or indirectly related (to the Apache) project types occurred.
