Scannable Millimeter Wave Arrays. Volume 2

Abstract : The complexity usually associated with scanning arrays at millimeter wavelengths produces fabrication difficulties, so that alternative methods are needed that employ simpler structures. This Final Report describes such an alternative scanning approach, and presents a group of new and simpler radiating structures suitable for millimeter-wave applications. The new class of scanning arrays described her achieves scanning in two dimensions by creating a one dimensional array of leaky-wave line-source antennas. The individual line sources are fed from one end and are scanned in elevation by electronic means or by varying the frequency. Scanning in the cross plane, and therefore in azimuth, is produced by phase shifters arranged in the feed structure of the one- dimensional array of line sources. Within the sector of space over which the arrays can be scanned, the radiation has negligible cross polarization, no blind spots and no grating lobes.
An analysis of dry county status and drinking and driving in Texas

Abstract The goal of this study was to explore county prohibitions of alcohol sales, mainly dry county (counties that have opted not to sell alcohol) versus wet county (counties that sell alcohol), and to examine its impact on drinking and driving in Texas. Data about automotive fatal crashes in the State of Texas between 2001 and 2005 were retrieved from the Fatality Analysis Reporting System (FARS). Logistic regression analyses were performed to determine the relationship between drinking and driving, county of residence and dry status, along with other factors. Findings from this analysis indicate that individuals who lived in wet counties were more likely to drink and drive and cause accidents in wet counties. Results from several of the models indicated that people who were from dry counties were less likely to be drunk and be involved in a fatal car accident.
Phylogenetic characterization and evolution of the VP4 gene of P[9] rotaviruses

Objectives: Rotavirus is one of the major causes of gastroenteritis in children under 5 years of age and is responsible for over 200,000 deaths annually. Rotavirus can evolve by reassortment, in which gene segments are exchanged between strains of different origins. Rotavirus strains with the P[9] genotype is an example of reassortment, in which the P[9] genotype is from feline species. A number of outbreaks by P[9] strains have been documented in several countries. However, details regarding the epidemiological relationships between the strains remains largly unknown. Therefore, in the present study, genetic characterization and evolutionary analyses were perforemd to gain insight into P[9] strains circulating in different parts of the world. Results: The P[9] strains could be divided into five lineages, and that the common ancestor of currently circulating P[9] strains is around 168 years old. In each lineage, the strains were not only from different countries, but also from different continents. These findings suggest that none of the lineages has a specific region of distribution, and although humans have had interactions with cats for thousands of years, the ancestor of the current P[9] strain is relatively recent.

Road condition estimation for traction control in electric vehicle

The target of our project is to realise a novel traction control system for an electric vehicle with four independently controlled in-wheel-motors. In each in-wheel-motor, the optimal slip ratio control is implemented beforehand to prevent wheel slip for vehicle stability control. The optimal slip ratio control is achieved by maintaining the slip ratio to the value to give the maximum road friction. This means that the driving force of the vehicle is fixed at its maximum level. As the driving force is affected by highly nonlinear adhesion characteristics between tire and road surface, real-time generation of the optimal slip ratio is necessary while the vehicle is moving. To estimate the adhesion characteristics, only the estimation of the slope of road friction curve is enough. To this aim, in this paper, the driving-force observer is newly designed to detect the road friction coefficient and the fixed-trace algorithm is applied to the slope estimation. The effectiveness of the proposed method is confirmed by simulation and experimental data obtained by laboratory-made electric vehicle "UOT Electric March".
Engineers’ Innovative Work Behavior: A Research with the Public Worker

The only way for the organization, to become more innovative is to capitalize on their employees’ ability to create and to innovate. The purpose of this study is to understand the impact of demographic factors on innovative work behavior of engineers, working for 5 th Highway Directorate in Turkey. The seven-item scale was used to assess employee innovative behaviors at the workplace. As a result most rated item by engineers, “I try to follow new techniques related to my job” is found. Furthermore, it is tested whether there are differences in the level of innovative work behaviors that can be attributed to demographic characteristics such as age, gender, experience, foreign language skills and found no significant differences according to demographic variables. The only significant difference has been found between positions of engineers and innovative work behavior.
Improving Prediction of Stock Market Indices by Analyzing the Psychological States of Twitter Users

In our paper, we analyze the possibility of improving the prediction of stock market indicators by conducting a sentiment analysis of Twitter posts. We use a dictionary-based approach for sentiment analysis, which allows us to distinguish eight basic emotions in the tweets of users. We compare the results of applying the Support Vector Machine algorithm trained on three sets of data: historical data, historical and “Worry”, “Fear”, “Hope” words count data, historical data and data on the present eight categories of emotions. Our results suggest that the Twitter sentiment analysis data provides additional information and improves prediction as compared to a model based solely on information on previous shifts in stock indicators.
Analysis of flash plate dipole EMP sensor using finite difference time domain method

A direct three dimensional finite difference time domain (FDTD) method is applied to the analysis of a flash plate dipole (FTD) sensor used for transient field measurements. The sensor response to a double exponential transient wave and a Gaussian pulse are obtained and analysed. The capacitance and the equivalent area of the sensor are obtained and their variations with the structural dimension of the sensor are determined and compared with that obtained by the conventional method.
A 140 - 170 GHz Low-Noise Uniplanar Subharmonic Schottky-Receiver

A 150-GHz Schottky diode subharmonic receiver based on a coplanar-waveguide-fed double-folded-slot (DFS) antenna is presented in this paper. The DFS antenna is placed on an extended hemispherical high-resistivity silicon substrate lens to achieve a high directivity and a high coupling to a Gaussian beam efficiency. The uniplanar receiver results in a 12±0.5-dB measured double-sideband conversion loss at 144-152 GHz for a 8-10 mW local-oscillator power at 77 GHz, and has a wide-hand l13-dB conversion loss over 30 GHz of bandwidth (140-170 GHz). The measured conversion loss includes silicon lens absorption and reflection losses, as well as IF mismatch losses. The applications are in new small aperture (7.5-cm lenses) collision-avoidance radars at 150 GHz.
Gochlear implants from model to patients

Cochlear implants (CI) are by now an accepted form of rehabilitation for profoundly deaf patients. CI users regain part of their hearing by direct electrical stimulation of the auditory nerve. With modern cochlear implants most users are able to achieve open-set speech understanding and are able to use the telephone. There are, however, still a lot of unanswered questions regarding the optimal design, stimulation paradigms, fitting methods and objective measurements. With the development of a realistic computer model of the implanted cochlea, as described in this thesis, these questions are analyzed from a fundamental perspective. This realistic model enables the analysis of clinical devices and gives insight in discrepancies between human and animal results. Insights gained from the model are used to improve clinical practice. Based on the model outcomes presented the characteristics of an improved electrode design were defined, and finally tested in a temporal bone study.
Redesigning Of Building Envelope: Tree Bark As A Biomimicry Concept

For years, nature has provided an abundance of blessings for mankind. Besides its obvious and direct role, the task that has been most evident is its ability of adaptation. Biomimicry has provided an inspirational foundation for many innovations. In this paper, tree bark has been chosen as the main focus of observation in order to scrutinize and analyse complex structures that contribute to the tree envelope’s efficiency. Many concepts have been extracted based on its anatomy and modifications. They have then been applied to a residential villa located in Dubai, United Arab Emirates (UAE) in order to create a low energy consumption building. The aim of this paper is to evaluate the extracted techniques thoroughly and discover the function and mechanisms of its parts. New strategies will be developed to apply to the selected case study. Shading, thermal insulation and cavity walls were among the used techniques. Eventually, the building’s performance with the new strategies will be evaluated using computer simulation software and compared to the original case. The paper revealed very promising results for enhancing the building envelope’s performance with the possibility of energy consumption reduction reaching around 34%.

Use of wavelet analysis techniques with surface EMG and MMG to characterise motor unit recruitment patterns of shouldermuscles during wheelchair propulsion and voluntary contraction tasks

The high demand on the upper extremity during manual wheelchair use contributes to a high prevalence of shoulder pathology in people with spinal cord injury. The overall purpose of this thesis was to investigate shoulder muscle recruitment patterns and wheelchair kinetics in able-bodied participants over a range of daily activities and mobility tasks requiring manual wheelchair propulsion. With a complete understanding of the muscle recruitment patterns, physiotherapists and wheelchair users can improve rehabilitation protocols and wheelchair propulsion performance to prevent shoulder pathology and maintain comfort during locomotion. Motor unit recruitment patterns were examined first during isometric and isotonic contractions to determine if spectral properties from EMG and MMG could be related to the different motor units in biceps brachii by using wavelet techniques coupled with principle component analysis. The results indicated that motor unit recruitment patterns can be indicated by the spectral properties of the EMG and MMG signals. EMG activity of 7 shoulder muscles was recorded with surface electrodes on 15 able-bodied participants over a range of manual wheelchair propulsion activities. Wavelet and principle component analysis was used to simultaneously decompose the signals into time and frequency domain. There are three main conclusions that can be drawn: 1) Uphill and faster speed (1.6m/s) propulsion required higher activity levels in the shoulder muscles and greater resultant joint force than did slow speed propulsion on the ergometer (0.9m/s), thus potentially resulting in shoulder pathology. 2) Prolonged wheelchair propulsion and greater muscle activity may result in fatigue and play a factor in the development of shoulder pain and pathology over time. 3) The instructed semicircular pattern has a positive effect on shoulder muscle recruitment patterns. Further investigations need to focus on a systematic integrated data collection and analysis of kinematic, kinetic, and electromyography (EMG) data from people with spinal cord injuries.
Um modelo integrado de simulação-otimização para a avaliação de um novo negócio de aeronaves de propriedade compartilhada

In this paper we describe a simulation-optimization model to help evaluate the feasibility of a new fractional ownership jets operation. This problem arises in the planning phase a new business to be launched, when it is necessary to evaluate alternative base location for the jets (how many and where) as well as to estimate the minimum required fleet size and the amount of deadhead (i.e. empty) trips that do not generate revenue. The problem of determining the fleet requirements, as well as allocation of jets to minimize the empty flights are modeled as a space-time minimum cost network flow model legs based on daily flight demands generated by Monte Carlo simulation. Our model was implemented in Excel spreadsheet with automation of all procedures related to the simulation and to building and solving the optimization model, in such a way that data can be easily inputted, updated and modified, and the models run in an easy and straightforward way by anyone with no required skills in operations research
Elucidation of the Molecular Consequences of Two Unique p6Gag Mutations Derived from HIV-1 CRF07_BC-infected Patients

Background We previously observed that individuals infected with HIV-1 CRF07_BC showed slower disease progression than those infected with HIV-1 subtype B or CRF01_AE. CRF07_BC viruses carry two unique mutations in the p6 Gag protein: insertion of PTAPPE sequences downstream of the original Tsg101 binding domain, and deletion of a seven-amino-acid sequence ( 30 PIDKELY 36 ) that partially overlaps with the Alix binding domain. To further define the role of these mutations in virus release and replication, we introduced them into the HIV-1 proviral clone pNL4-3 for functional characterization. Results We found that the seven-amino-acid deletion, but not the PTAPPE insertion, significantly decreased virus release, Gag processing, and virus infectivity. The seven-amino-acid deletion also resulted in a virus replication defect in both T-cell lines and peripheral blood mononuclear cells. We found that these defects were caused by the seven-amino-acid deletion in p6 Gag , especially deletion of Tyr-36 of p6 Gag , not the deletion of the overlapping p6* sequence in the HIV-1 GagPol protein. The p6 Gag deletion mutant was resistant to a dominant-negative Alix fragment, suggesting a loss of binding between p6 Gag and Alix. Conclusions Our results indicate that the patient-derived seven-amino-acid deletion in p6 Gag of HIV-1 CRF07_BC virus affects virus release, infectivity and replication capacity by disrupting the interaction between HIV-1 p6 Gag and host protein Alix. These results may explain the slower disease progression observed in the subjects infected with HIV-1 CRF07_BC bearing this unique mutation.
A New Fashion: Dressing Up the Cities

Abstract The aim of this article is to explore the urban knitting movement, a worldwide phenomenon that tries to combine a domestic activity, street or folk art, the reshaping of do-it-yourself culture, and peaceful forms of urban guerrilla protest. The activists employ colorful displays of knitted or crocheted cloth to enhance, beautify, personalize, and gentrify abandoned public places. Furthermore, they use the Internet to share knowledge on techniques and experiences, to organize collective actions, and to record and document their artistic installations. This article is focused on an urban knitting project realized in L'Aquila (Italy) three years after the 2009 earthquake. It was called “Mettiamoci una pezza” (“Let's Patch It”). The main aim of this project was to “dress up” the main square of the city, covering the gray metal barricades that still block off citizens from some areas of downtown and adding a sprinkle of color and warmth to the devastated city. We studied this movement in an ethnographic way, by applying a qualitative content analysis of the online materials and nonparticipatory observation of this event in L'Aquila in order to investigate what the collective action did both practically and symbolically. Our research shows how the movement was able to promote a very complex and meaningful political initiative.
“Dark Knowledge”

This paper is about the dark realm of knowledge that is nuclear science. I discuss the uses and abuses of this knowledge over the last century, and an installation project I developed that seeks to manifest such dark knowledge, titled Demon Core (2019). To enframe this discussion, I shall start with some quotes from a somewhat dark materialist philosopher Martin Heidegger and his key text, The Question Concerning Technology (1977). Heidegger says that technology is no mere means. It's a way of “ revealing ” , which is a sort of knowing in the wider material sense - through our interactions with matter, working with matter, making matter do things, one gains material knowledge. Technology, the tools and techniques we use to work with matter, is a mode of “ revealing ” aspects or attributes of nature. Heidegger asks ‘ What is modern technology? It too is a revealing. …And yet … The revealing that rules in modern technology is a challenging’ . [1] Con-temporary technology is different to traditional technologies, as it's based on modern science and engineering. Technology challenges nature and drives it to do certain things, such as taking the energy that naturally exists within a river and using it through the technology of a dam. Technology based upon modern physics takes this to a much more fundamental level: ‘ The Earth is now set upon to yield uranium. Uranium is set upon to yield Atomic Energy, which can be released either for destruction or for peaceful use … . This setting upon that challenges for the energies of nature is an expediting in two ways. It unlocks and exposes … That challenging happens in that the energy concealed in nature is unlocked, what is unlocked is trans-formed…’ . [2] Through such challenging and transforming of materials and energies, technology enframes nature, challenges it, summoning it forth and forcing it to work for us, in ways against its innate tendencies . A darkly archetypal example of this is the atom bomb. The 20th and
Flexural Vibration of Symmetrical Multi-Layer Beams with Viscoelastic Damping:

The flexural vibrations of beams can be reduced by introducing sandwiched layers of energy-dissipating materials. The equations of motion are derived for flexural vibrations of symmetrical, multi-layer sandwich beams. Two types of beams are considered, depending on whether the central layer is energy dissipating when the number of layers will be n = 4i − 1, where i = 1, 2,…, or whether the material of the central layer is perfectly elastic when n = 4i + 1. The total number of equations of motion will be i + 1 for each type. These equations will be non-linear when the properties of the energy-dissipating materials are strain dependent. A numerical method of solution has been introduced by transforming the equations of motion into sets of non-dimensional simultaneous equations and using finite difference methods. The simplest type of beam has three layers but even this leads to a set of four simultaneous equations of the twelfth order.It is shown as an example that the strain dependence of a typical viscoel.
Study on Impedance Calculation of Viscoelastic Material in Acoustic Tube

The validated finite element method (FEM) was applied to the calculation of local impedance of viscoelastic sample in the acoustic tube. The acoustic impedance of viscoelastic material was calculated by three methods on the basis of numerical acoustic field computed by fluid-structure coupling method and the structure itself. The comparisons of calculation results illustrate that acoustic impedance is the inherent attribute of material.
Surface-micromachined 1MHz oscillator with low-noise Pierce configuration

A prototype high frequency tuning fork oscillator has been fabricated and tested in an integrated surface micromachining technology. The amplifier circuitry uses a capacitive current detection method, which offers superior noise performance over previous resistive methods. The prototype device has an output frequency of 1.022 MHz and exhibits a noise floor of {minus}88 dBc/Hz at a distance of 500 Hz from the carrier. The dominant source of frequency instability is the nonlinearity introduced by the use of parallel plate actuation.
