Model for microwave absorption and heat transfer in a combination washer dryer

The work presented within this dissertation focusses on the development of a finite element method (FEM) model for the microwave absorption and heat transfer within a microwave combination washer dryer (MCWD). FEM will be used to aid in the implementation of more advanced fluid dynamics such as laminar or turbulent flow, that may be present within the system. The intended use of the model is to aid a South African based company in the development of a control system for the MCWD. The model development presented focusses on the washing cycle of the MCWD and will therefore not take into account the drying cycle of the system. The target of the microwave heating within the model will be distilled water as the dielectric constant of water is a know quantity. Various literature sources on microwave absorption and heat transfer models can be found, but none specific to the topic of the combination washer dryer. By reviewing literature from various sources, the finite element method was selected as the modelling technique and the COMSOL® software package was selected as the tool for developing the model. A model for the MCWD will be developed within the COMSOL® environment which in turn implements FEM as a technique to solve the model. The model development is broken into nine stages. Stage one start by modelling the heat transfer within the washing drum. Each consecutive stage expands the model by adding features or model domains. Model verification takes place in parallel to the development by verifying each stage before moving to the next stage. The stage eight and nine models, which represent a full three dimensional model of the system, are selected to be validated as the final models. Stage eight models the system without an enclosure and makes use of convective cooling boundary conditions on the boundary of the air enclosed within the system enclosure. Stage stage nine models the system with the aluminium enclosure of the system and also implements convective cooling boundary conditions on the outer boundary of the aluminium. The boundary between the enclosed air and aluminium enclosure is implemented as a normal convective heat transfer boundary between a gas and solid. Data capturing is done using the dSpace® platform. Sensors to log the microwave power and system temperature are selected and optimal placement of the sensors is evaluated. The
Human motor control through electrocorticographic brain machine interfaces

of Dissertation Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy HUMAN MOTOR CONTROL THROUGH ELECTROCORTICOGRAPHIC BRAIN MACHINE INTERFACES By Aysegul Gunduz August 2008 Chair: Jose C. Principe Major: Electrical and Computer Engineering Brain machine interfaces (BMIs) aim to provide new rehabilitation options and channels of interaction to patients who have lost their ability to move their limbs due to disease or injury to the central or peripheral nervous system. Brain activity produces a variety of electrical signals that can be measured through diverse recording technologies and are potential candidates for BMI inputs. Electrocorticogram recordings (ECoG) provide an intermediate level of abstraction between invasive microarray recordings that penetrate the tissue and noninvasive scalp recordings (EEG). In order to map ECoG activity to motor behavior, extraction of the appropriate spatiotemporal and spectral control features is critical. Though they provide higher amplitude, less noisy and broader band signals compared to EEG recordings, extraction of signatures of motor events in spontaneous ECoG activity still entails challenges and remains unexplored. Herein, clinical behavioral paradigms are developed to record and analyze very broadband ECoG from two epileptic patients participating in reaching, pointing and cursor tracking tasks. Although historically frequencies above the high gamma band have been discarded as background activity, we study all frequencies upto the Nyquist frequency (of 6.1kHz) by dividing the broadband into logarithmically equal bands, yielding passbands of equal center frequency to bandwidth ratio. The role of the spectral resolution, in which the broadband is partitioned, in the reconstruction of the patients’ hand trajectories is studied through crosscorrelations, event related synchronizations, directional tuning, and source separation
Manual of Standardization in the Romance Languages

: In linguistic pragmatics norms can be seen as traditions that guide verbal interaction. In order to pin down the notion of tradition, we use a model of linguistic pragmatics that goes back to Eugenio Coseriu’s system of linguistic competence and to the concept of tradition elaborated by Ramón Menéndez Pidal, thus bringing together linguistics and philology. The functioning of norms as traditions is illustrated with two examples: with a routine of verbal politeness and with a narration style that is based on the aspect system of Romance languages and functions as a cultural tradition.

Design and Development of Timmi - An Interferometric Radar

Interferometry has gained importance as a remote sensing te chnique to study topography, topographic change and volume and surface scattering p operties of various natural targets. Interferometric radars rely on the ability to accu rately measure amplitude and phase between signals received on two spatially separated a n nnas. The accuracy required for interferometric measurements place tight constraints o the performance of the radar hardware. This thesis details the development, constructi on and testing of a two-stage, two-channel Ku band downconverter ( also referred to as Dual Channel Downconverter or DDC)which forms the core of the interferometer to meet th requirements to make highly accurate interferometric measurements.
Genome-wide identification of expansin gene family reveals expansin genes are involved in fibre cells growth in cotton

Background : Expansins ( EXPs ), a group of proteins that loosen plant cell walls and cellulosic materials, are involved in regulating cell growth and diverse developmental processes in plants. However, the biological functions of this gene family are still unknown in cotton. Results: In this paper, we identified a total of 93 expansin genes in Gossypium hirsutum . These genes were classified into four subfamilies, including 67 GhEXPAs , 8 GhEXPBs , 6 GhEXLAs , and 12 GhEXLBs , and divided into 15 subgroups. All 93 expansin genes are distributed over 24 chromosomes excluding Ghir_A02 and Ghir_D06. All GhEXP genes contain multiple exons and each GhEXP protein has multiple conserved motifs. Transcript profiling and qPCR analysis revealed that the expansin genes have distinct expression patterns in different stages of cotton fibre development. Among them, 3 genes ( GhEXPA4o , GhEXPA1A , and GhEXPA8h ) were highly expressed in the initiation stage, 9 genes ( GhEXPA4a , GhEXPA13a , GhEXPA4f , GhEXPA4q , GhEXPA8f , GhEXPA2 , GhEXPA8g , GhEXPA8a , and GhEXPA4n ) had high expression during the fast elongation stage, while GhEXLA1c and GhEXLA1f were preferentially expressed in the transition stage of fibre development. Conclusions: Our results provide a solid basis for further elucidation of biological functions of expansin genes in cotton fibre development and valuable genetic resources used for crop improvement in the future.
Integrative Bioinformatics Analysis Identified Hub Genes in Association with Development of Lung Adenocarcinoma

Background: Cancer-related death is mainly caused by lung adenocarcinoma (LUAD), an aggressive malignant tumor. Therefore, the identification of important LUAD-related genes and the further analysis of its prognostic significance are critical for the survival of LUAD patients.Methods: Weighted Gene Co-expression Network Analysis (WGCNA) and differential gene expression analysis methods were adopted to screen out TCGA-LUAD database and the gene expression profiles of GSE32863 from GEO. Functional annotation analysis and protein-protein interaction (PPI) network were conducted on differential co-expression genes. Furthermore, survival analysis was carried out on twelve hub genes that were identified by applying the CytoHubba plugin of Cytoscape. Finally, we validated the protein level of survival-related gene in HPA database.Results: A total of 358 differential co-expression genes were extracted from the database of TCGA and GEO. These genes were mainly enriched in extracellular structure organization, cell−substrate adhesion and response to acid chemical (biological process), cell−cell junction and collagen−containing extracellular matrix (cellular component), DNA−binding transcription activator activity, glycosaminoglycan binding, and growth factor binding (molecular function). In the KEGG analysis, the main pathways were Drug metabolism−cytochrome P450. Moreover, in a PPI network, the 12 hub genes (GNG11, ADRB2, ADCY4, TGFBR2, IL6, GPC3, VIPR1, GRK5, CAV1, RAMP3, RAMP2, and CALCRL) were identified. The expression level of ADCY4, VIPR1, and TGFBR2 was corresponded with clinical stages and overall survival (OS) in LUAD patients. Finally, the protein level of ADCY4 and VIPR1 was down-regulated consistently with mRNA levels in LUAD samples.Conclusion: Perhaps, ADCY4, VIPR1 and TGFBR2 play important role in tumorigenesis, so they will serve as prognostic biomarkers and therapeutic targets of LUAD in the future.
Measuring of mechanical properties of human skeletal muscle related to muscular tone under in vivo compression

Subjective techniques are widely employed for measuring skeletal muscle tone while objective methods are scarcely used in clinical and research practice, because there is no precise description of this natural phenomenon in physical terms.The aim of the study is to determine indexes that are indicative of muscle tone, based on the pure physical internal properties of skeletal muscle in vivo. Muscle was tested and data analysed using the load deformation relationship applied to skeletal muscle. The first dorsal interosseous muscles on the both sides (trained and untrained) were subsequently automatically compressed and decompressed. The automatic equipment developed by the authors allows the objective and rapid measurement of multiple characteristics of muscle tone. Twenty strongly right-handed young males returned three data acquisition sequences from each hand. From the sequences the specific energy and power of compression and recoil along with muscular "set" was determined. Indexes that best reflect muscle tone are dissipating energy, power, and muscle "set".
Towards Postural Synergies for Caging Grasps

Postural synergies have in recent years been successfully used as a low-dimensional representation for the control of robotic hands and in particular for the synthesis of force-closed grasps. This work proposes to study caging grasps using synergies and reports on an initial analysis of postural synergies for such grasps. Caging grasps, which have originally only been analyzed for simple planar objects, have recently been shown to be useful for certain manipulation tasks and are now starting to be investigated also for complicated object geometries. In this workshop contribution, we investigate a synthetic data-set ofcaging grasps of four robotic hands on several every-day objects and report on an analysis of synergies for this data-set.
Toward a Global Cybersecurity Standard of Care? Exploring the Implications of the 2014 NIST Cybersecurity Framework on Shaping Reasonable National and International Cybersecurity Practices

Even though U.S. congressional and multilateral efforts aimed at enhancing cybersecurity have thus far largely failed in their aims, courts are using existing doctrines including negligence to hold companies accountable for cyber attacks. However, decisions have been largely haphazard due in part to confusion over what constitutes cybersecurity best practices. This Article analyzes the emerging cybersecurity duty of care, and examines the potential impact of the 2014 National Institute of Standards and Technology (NIST) cybersecurity framework on particularly on negligence law. Given that best practices are not yet well-defined in this space, the NIST framework has the potential to help define the standard for not only critical infrastructure firms, but the private sector writ large. There is some evidence this is already happening, such as in reference to an FCC/telecom release in November 2013: “The telecommunications industry and the Federal Communications Commission plan to use an emerging framework of cybersecurity standards to assess and prioritize best practices for the sector as it works to address evolving cyber threats. ” The NIST framework has the potential to shift the cybersecurity landscape not only in the United States, but also potentially in other jurisdictions favoring a largely voluntary approach to enhancing cybersecurity such as the United Kingdom, the European Union, and India. For businesses active across jurisdictions, and depending on the uptake of the NIST framework by stakeholders, a global duty of cybersecurity care could emerge that would promote consistency and contribute to cyber peace even absent regulatory action.
Landscape and evolution of cis- and trans-regulatory divergence in chicken genome between two contrasted breeds analyzed in three tissues at one day age

Background: Gene expression variation is an important mechanism underlying phenotypic variation, and can occur via cis- and trans-regulation. In order to understand the role of cis- and trans-regulatory variation on population divergence of chicken, we developed reciprocal crosses of two chicken breeds, White Leghorn and Cornish Game, with major differences in body size and reproductive traits, and used them to identify the degree of cis versus trans variation in brain, liver and muscle of both male and female samples at 1 day age. Results: We provided a landscape about how the transcriptomes are regulated in the hybrid progenies of two contrasted breeds by allele specific expression analysis. Our results showed that compared with the cis-regulatory divergence, trans-acted genes existed more extensively in the chicken genome. Furthermore, a widespread tendency of compensatory regulation exists in chicken genome. Most importantly, we found the evidence of stronger purifying selection on genes regulated by trans variations than the cis elements. Conclusions: We demonstrated a pipeline to explore the allele-specific expression in the hybrid progenies of inbred lines without specific reference genome. Our research performed the first study to describe the regulatory divergence between two contrasted breeds. The results suggested that artificial selection associated with domestication in chicken may have more often acted on trans-regulatory divergence than cis.

Optimum Receiver Design for MIMO Fading Channels

This thesis describes the analytical design and the performance analysis of optimum receivers for Multiple Input - Multiple Output (MIMO) fading channels. In particular, a novel Optimum Receiver for separately-correlated MIMO channels is proposed. This novel pilot-aided receiver is able to process jointly the pilot symbols, transmitted within each time frame as a preamble, and the information symbols and to decode the transmitted data in a single step, avoiding the explicit estimation of the channel matrix. The optimum receiver is designed for the following two scenarios, corresponding to different transmission schemes and channel models: 1) Narrowband Rician fading MIMO channel with spatial separate correlation; 2) MIMO-OFDM Rician fading channel with space and frequency separate correlation. For each system the performance of the optimum receiver is studied in detail under different channel conditions. The optimum receiver is compared with: - the ideal Genie Receiver, knowing perfectly the Channel State Information (CSI) at no cost; - the standard Mismatched Receiver, estimating the CSI in a first step, then using this imperfect estimate in the ideal channel metric. Since the optimum receiver requires the knowledge of the channel parameters for the decoding process, an estimation algorithm is proposed and tested. Moreover, a complexity analysis is carried out and methods for complexity reduction are proposed. Furthermore, the narrowband receiver is tested in realistic conditions using measured channel samples. Finally, a blind version of the receiver is proposed
Explosive Detection in Aviation Applications Using CT

CT scanners are deployed world-wide to detect explosives in checked and carry-on baggage. Though very similar to single- and dual-energy multi-slice CT scanners used today in medical imaging, some recently developed explosives detection scanners employ multiple sources and detector arrays to eliminate mechanical rotation of a gantry, photon counting detectors for spectral imaging, and limited number of views to reduce cost. For each bag scanned, the resulting reconstructed images are first processed by automated threat recognition algorithms to screen for explosives and other threats. Human operators review the images only when these automated algorithms report the presence of possible threats. The US Department of Homeland Security (DHS) has requirements for future scanners that include dealing with a larger number of threats, higher probability of detection, lower false alarm rates and lower operating costs. One tactic that DHS is pursuing to achieve these requirements is to augment the capabilities of the established security vendors with third-party algorithm developers. A third-party in this context refers to academics and companies other than the established vendors. DHS is particularly interested in exploring the model that has been used very successfully by the medical imaging industry, in which university researchers develop algorithms that are eventuallymore » deployed in commercial medical imaging equipment. The purpose of this paper is to discuss opportunities for third-parties to develop advanced reconstruction and threat detection algorithms. « less
Knowledge Management in Virtual Environments

1. Introduction Knowledge is power. It has become the product of the modern office and the information, the primary raw material. Knowledge flows among human and organisational knowledge processes and structures that are the key to organisational performance. Tacit knowledge, that exists either in the minds of the knowledge workers or in a meeting within an organisation, needs to become explicit and available for many people to use and apply. Knowledge management strategy can support this objective if its development has been based on the understanding of the organisation in which it is applied. This understanding includes the organisational culture, processes the infrastructure as well as the human communication. Knowledge management should be able to encourage the communication among the people within an organisation for the creation and sharing of knowledge, rather than being a collection of individual's knowledge, especially when the organisation is distributed. The aim of this research is a further study on how can technology help distributed organisations extract knowledge from human communication among mobile knowledge workers by establishing common understanding in physical and mediated spaces and what are the necessary metaphors in such an environment.
New results for differentially detected [pi]/4 DQPSK signal in a direct-conversion transceiver

approvedJohn T. Sto Sayfe Kiaei As the world of mobile communications has evolved from an analog to a digital technology, the design goals for new cellular phones have become low cost and small weight. In this thesis, we present new results related to the design of a direct-conversion transceiver for IS-54, which is the North-American TDMA standard for cellular telephony. The direct-conversion transceiver has desirable features: low complexity and low power consumption. However, this transceiver is sensitive to distortions such as gain and phase imbalances and DC offset. These imbalances are caused by imperfections of the employed analog devices and become larger at higher frequencies. At the transmitter, these distortions deteriorate the performance of the predistortion circuit necessary for the power amplifier linearization. In this thesis, we present several new results and ideas. First, a new theoretical expression for the Bit-Error Rate of a differentially detected 4 DQPSK system (IS-54) in presence of either gain or phase imbalance at the receiver is derived. This new derivation will be compared successfully with simulations of the same system. Second, a method for the estimation and the correction of the gain and the phase imbalances in a directconversion transmitter is presented. This approach will be shown to require little extra circuitry to theoretically work perfectly and to be limited by the resolution of the Analog to Digital Converter added at the transmitter.

On The Efficacy of Alternate Menu Configurations

approved: _________________________________________ Mike Bailey Extensive research has been conducted to improve the menus that allow navigation of digital world, most of it focused on the most common varieties of menu. Radial menus, a less common menu variety designed so that menu entries are aligned on a polar coordinate system, have largely been ignored. Early studies focused on radial menus predicted significant user experience benefits in certain applications, but the relative dearth of modern work has made it difficult to determine the optimal applications for radial menu interfaces. One specific area of study that has been neglected is the application of radial menus in an Internet setting. The goal of this research is to establish a baseline comparison between an extremely simplistic nested radial menu and a similar list menu, of the kind that can be found throughout the Internet. The test platform consists of a brief web navigation exercise. Participants will navigate through a web-page using either a radial menu or a list menu and the website will collect the completion times for the different menu types.
