A self-aligned vertical comb-drive actuator on an SOI wafer for a 2D scanning micromirror

A self-aligned vertical comb-drive actuator for a two-axis tilt scanning micromirror is presented. Self-alignment between moving and fixed fingers is essential in order to avoid lateral instability leading to an in-plane rotational pull-in during an actuation. Multilayered masking films have been utilized to fabricate the self-aligned comb fingers. To generate high electrostatic torque, high-aspect ratio comb-drive actuators with 40 µm thick fingers have been realized on a silicon-on-insulator (SOI) wafer utilizing deep reactive ion etching (DRIE) technology. A delay-mask process (DMP) was employed in an etching step of a silicon device layer to assist etching of a buried oxide (BOX) layer at the bottom of narrow (5 µm) and deep (40 µm) silicon trenches. The DC mechanical scan angles of the actuators employed in the two-axis tilt, gimbal-configured micromirror were measured as ±2.1° at 48 V around an inner axis and ±1.8° at 44 V around an outer axis, respectively. The fabricated micromirror with a mirror area of 1 mm × 1 mm has mechanical resonant frequencies of 1.2 kHz around the inner axis (a mirror only) and 0.9 kHz around the outer axis (a frame and the mirror), respectively.
Experimental Investigation of the Aerodynamic Performance of a Linear Axial Compressor Cascade With Water Droplet Loading

Wet compression operation is a commercially attractive way to increase power output and efficiency of a gas turbine cycle. In recent literature the impact of water loading on the aerodynamic performance of the blading has not been entirely clarified yet. The most significant issues of aerodynamics in wet compression are stage rematching and stability. Therefore, these subjects are investigated in a linear compressor rotor cascade. This setup allows an estimation of the aerodynamic performance of the blading from two-dimensional test data at various operating conditions. Moreover, the impact of droplet flow on the two-dimensional flow field of the blade passage is measured in detail in order to understand the deviation of performance parameters. The results indicate that the effect of water injection on compressor aerodynamics is strongly related to the operating condition. It appears that droplet loading has a beneficial effect on the flow at high blade loading.Copyright © 2010 by ASME
Cross-Modality Domain Adaptation for Medical Image Segmentation

Domain Adaptation (DA) has recently raised strong interests in the medical imaging community. By encouraging algorithms to be robust to unseen situations or different input data domains, Domain Adaptation improves the applicability of machine learning approaches to various clinical settings. While a large variety of DA techniques has been proposed for image segmentation, most of these techniques have been validated either on private datasets [4,5] or on small publicly available datasets [6,7,8,9]. Moreover, these datasets mostly address single-class problems.
Aeroacoustic Characterization of T-Junctions Based on Large Eddy Simulation and System Identification

The aeroacoustic behavior of T-junctions in pipe networks is investigated. The configuration consists of a main pipe with mean flow and a side branch without mean flow. The coefficients of transmission and reflection of plane acoustic waves for the junction are determined numerically by means of a combination of large eddy simulation and system identification. In addition, the production and absorption of acoustic energy due to an interaction of the unstable shear layer with the impinging acoustic waves is studied utilizing the scattering coefficients. The comparison of the numerical results with available experimental data demonstrates excellent agreement. The results obtained can be applied to assess the aeroacoustic stability of pipe systems which include T-junctions.
PROCEEDINGS of the HUMAN FACTORS SOCIETY-27th ANNUAL MEE7lNG--1983 KEYBOARD DESIGN: AN INVESTIGATION OF USER PREFERENCE AND PERFORMANCE

This study investigated the effects of several alphanumeric keyboard characteristics including: audible feedback; location, size, and shape of the carriage return key; and the shape and style of keycaps. Four of the six keyboards were experimental prototypes, while the remaining two were production models. Eighteen subjects were used in a mixed factorial design. Subjects performed a text entry task during which they were not allowed to correct any errors. Four types of data were collected: 1) total errors per trial, 2) total time for text entry, 3) indivkdual preference questionnaire data for each keyboard, and 4) comparative questionnaire data across keyboards. Results indicate that time on task was not significantly different among keyboards; however, with audible feedback, a marginally significant result was found. Highly trained typists committed significantly more errors than did the other two less experienced groups. Subjects indicated that the location, size, and shape of the return key were important factors for keyboard design. Across groups, subjects preferred the capability for audible feedback.

Style previewing in 3D using name‐based sewing rules

Purpose – The purpose of this paper is to combine patterns from different garment sets and preview garment styles in 3D apparel design by giving sewing names to patterns and sewing edges.Design/methodology/approach – A new rule for 3D garment sewing is made. Unlike conventional vertex number‐based method, patterns and their edges are given specific names. If two edges have a same edge name, they make a sewing line. Thus, patterns from different garments can be combined and draped with this method. Numbers of boundary mesh nodes were controlled using B‐Spline to combine sewing edges of different lengths.Findings – It is found that by only assigning names to patterns and sewing edges, garment style can be previewed by substituting patterns.Originality/value – Styles and details of garments can be previewed in 3D by mixing patterns of different garment sets like in 2D technical flat sketching. Even patterns with different edge lengths can be combined by controlling the pattern meshes using B‐Spline.
A novel double-circuit-rotor balanced induction motor for improved slip-energy recovery drive performance. II. Experimental verification and harmonic analysis

The merits of the new slip-energy recovery drive system that has been proposed in Part I of this paper (see ibid., vol.11, no.3, p.556-62, 1996) is demonstrated here. Experimental work is carried out to verify the simulated, models of the proposed and conventional systems. Furthermore, harmonic analysis of both systems is conducted analytically and confirmed numerically using the FFT. The main feature of the new proposed system is the significant reduction in the harmonics of the rotor flux linkage. This leads to substantial reductions in the stator current harmonics. Moreover, the pulsating components in the developed electromagnetic torque are also reduced significantly in the new proposed system.
Application of acoustic emission for monitoring shear behavior of bonded concrete–rock joints under direct shear test

Studying shear behavior and failure mechanism of concrete–rock interfaces between concrete structures and rock mass is highly important. To this end, laboratory direct shear tests were conducted on several bonded interfaces. The effect of normal stress, displacement rate, and bonding percentage on shear behavior of bonded joints were also evaluated. The results showed that the adhesive bond between concrete and rock has the most important effect on shear mechanism of concrete–rock interfaces. When the normal load is low, the asperities do not contribute in shear process, so the shear strength of the joints is governed by adhesive bond. The only contribution of the asperities is that they show a small peak after bond breaking peak. When the normal load is high, the asperities break simultaneously with adhesive bond and they show their contribution in the whole shear process. In a constant normal load, by decreasing bonding percentage, the brittle failure of the bonded joints is changed into softening failu.
Directional Force Sensation by Asymmetric Oscillation From a Double-Layer Slider-Crank Mechanism

By subjecting a small object in a handheld device to periodic translational motion with asymmetric acceleration (accelerated more rapidly in one direction than in the other), the holder typically experiences the kinesthetic illusion of being pushed or pulled continuously by the held device. We have been investigating the effect because of its potential application to a handheld, nongrounded, haptic device that can convey a sense of a continuous translational force in one direction. A one-degree-of-freedom haptic device based on a double-layer slider-crank mechanism was constructed based on the results of our previous research. Our results with the new haptic device show that (i) humans perceive directed force sensation by asymmetric oscillation, (ii) 5 counts/s is the best frequency to generate the force sensation, (iii) the ratio of the gross weight of the device and the weight of the reciprocating mass should be at least 16% for effective force perception, and (iv) the force perception is the same with the device held in either hand.
A review paper on memory fault models and test algorithms

Testing embedded memories in a chip can be very challenging due to their high-density nature and manufactured using very deep submicron (VDSM) technologies. In this review paper, functional fault models which may exist in the memory are described, in terms of their definition and detection requirement. Several memory testing algorithms that are used in memory built-in self-test (BIST) are discussed, in terms of test operation sequences, fault detection ability, and also test complexity. From the studies, it shows that tests with 22 N of complexity such as March SS and March AB are needed to detect all static unlinked or simple faults within the memory cells. The N in the algorithm complexity refers to Nx*Ny*Nz whereby Nx represents the number of rows, Ny represents the number of columns and Nz represents the number of banks. This paper also looks into optimization and further improvement that can be achieved on existing March test algorithms to increase the fault coverage or to reduce the test complexity.

Specifically, this paper describes the design, development, and validation process we followed to create a competency model that defines the levels of performance and behaviors required to develop expertise in each of the taxons delineated in the Perceptual Training and Skills Taxonomy. The paper begins with a description of how the model fits into the overall project and then provides a rationale for the model based on existing research. Following initial development, focus groups were used to validate the Competency Model of Perceptual-Cognitive Skills with experienced military personnel and ensure that it not only reflects current literature but also accurately depicts real-world situations.
RF MEMS membrane switches on GaAs substrates for X-band applications

Micromechanical switches have demonstrated great potential at microwave frequencies. For low-loss applications at microwave frequencies, it is important to use high-resistivity substrates. This paper presents the design and fabrication of the shunt-capacitive MEMS switch on GaAs substrates. Analytical mechanical and impedance models of the membrane switch are given, and the results are confirmed by using the ANSYS and HFSS software, respectively. A surface micromachining process, which is compatible with the conventional millimeter-wave integrated circuits (MMICs) fabrication technology, was adopted to fabricate the RF switch on GaAs substrates. Its S-parameter was taken using a HP8510C vector network analyzer and a Cascade Probe station. The measured insertion loss of the switch and its associated transmission line is less than 0.25 dB from 1 to 25.6 GHz, and the isolation may reach -42 dB at its self-resonate frequency of 24.5 GHz. The actuation voltage is about 17 V. The switch has demonstrated lifetimes as long as 5/spl times/10/sup 6/ cycles. The wideband high performance in isolation and insertion loss offers the monolithic integration capability with GaAs MMICs.
A National Model for Strategic Planning of Infrastructure Systems

Governments worldwide are paying increasing attention to the role of infrastructure systems in promoting economic growth and environmental sustainability. However, infrastructure planning and provision tend to be addressed in sector-specific silos which overlook the interdependencies between sectors and focuses upon the provision of projects rather than the performance of systems. In this paper, the authors report on the development of the National Infrastructure System Model (NISMOD) family of models and, in particular, the NISMOD-LP model, which is a national model of the long-term performance of infrastructure systems. NISMOD-LP is driven by high-resolution demographic projects and regional multi-sectoral economic scenarios. These provide the basis for scenarios of future demand for infrastructure services. Separate modules simulate the future capacity and performance of energy, transport, water, waste water and solid waste sectors. These different perspectives are integrated through a common architecture for sampling uncertainties, construction of cross-sectoral policy responses and visualisation of future infrastructure performance.
Embedded computer design choices and solutions

Military avionics designers and policy makers are focusing on commercial hardware and software components as an opportunity to save development costs. However, such components are often designed without embedded computing applications in mind. Therefore, it can be problematical to evaluate commercial vendor performance gains in comparison to embedded computer system requirements. This paper ties together performance modeling methodologies for both computer types as a first step in answering such systems engineering questions. <<ETX>>
Modeling and analysis: power injection model approach for high performance of electrical distribution networks

The generation of electrical energy varies depending on the needs of the user, initial requirements, capacity, intended use, waste generation, and economic efficiency. In order to meet the challenges of the proposed overvoltage of the presented system, it is possible to use the solar collectors and profit from them economically through smart grid smart control systems. The mathematical model with four main parts was created: simulation, correlation, and evaluation according to the solar program set of photovoltaic solar modules, maximum power point tracking (MPPT), an adaptive neuro-fuzzy inference system (ANFIS) controller, and 600-volt electric network. Then in this phase, the investigation of the effects on the network on the basis of the output power with the coincidence of radiation and the effect of temperature in the network is carried out. An analysis was carried out to evaluate the impact of these fundamental limitations in practical application. In this section, the simulation of the proposed system is discussed. The block diagram of the developed system is presented in the last part. The proposed system was assessed from the Matlab simulation tapes and graphs for each part of the system, and the results of the overall system simulation were taken into account.

Crisis Management, Policy Reform, and Institutions: The Social Policy Response to COVID-19 in Australia

Social policy represents a critical dimension of the governmental response to COVID-19. This article analyses the Australian response, which was radical in that it signalled an unprecedented policy turnaround towards welfare generosity and the almost total relaxation of conditionality. It was also surprising because it was introduced by a conservative, anti-welfarist government. The principal argument is that, though the generosity was temporary, it should be understood simultaneously by reference to institutional change and institutional tradition. The ‘change’ element was shaped by the urgency and scale of the crisis, which indicated an institutional ‘critical juncture’. This provided a ‘window of opportunity’ for reform, which would otherwise be closed. ‘Tradition’ was reflected in the nation’s federalist conventions, which partially steered the response. The central implication for other countries is that, amid the uncertainty of a crisis, governments need to consider change within the bounds of their traditional institutions when introducing welfare reform.
Effects of replacement different levels and sources of methionine with betaine on jejunal morphology, duodenal mitochondrial respiration, and lipid peroxidation in heat-stressed broiler chickens

Abstract This study aimed to investigate the effects of replacement different levels and sources of methionine (Met) with betaine on jejunal morphology, duodenal mitochondrial respiration, and lipid peroxidation in heat-stressed broiler chickens. A total of 1,200 one-day-old Ross 308 broilers were randomly assigned to two similar poultry houses. The experiment was designed as a 2 (ambient temperatures) × 2 (Met sources) × 3 (Met levels) × 2 (betaine amounts) split-plot factorial arrangement. Basal diets (Low-Met) were formulated with DL-or L-Met to meet Ross 308 nutrient recommendations except for Met which was 30% lower than the recommendation. Met level in basal diets was increased to the recommendation and/or 30% more than recommendation (High-Met) by supplemental DL-or L-Met. Betaine was or was not partially substituted at a 30% equivalent level of supplemental DL- or L-Met. HS was induced by increasing ambient temperature to 32 °C for 6 h daily in one house from 10 to 42 d. The highest feed conversion ratio (FCR) was observed in Low-Met diets. Low-L-Met diets showed greatest FCR than Low-DL-Met diets groups. Breast muscle malondialdehyde (MDA) concentration was decreased by increasing dietary Met level under HS. Duodenal MDA concentration and complex (Cox) III activity was lower and higher in L-Met diets than DL-Met diets, respectively. Cox II activity was increased in High-Met diets, and also was improved by betaine replacement. Villus height (VH) and Villus surface (VS) was increased in L-Met diets compared to DL-Met diets. Generally, L-Met was more effective than DL-Met in jejunal morphology, reducing duodenal MDA, and increasing Cox III activity. Betaine had the potential to be a partial replacement for Met. HIGHLIGHTS L-Met was more efficient than DL-Met in duodenal malondialdehyde concentration and complex III activity. Heat stress reduced the growth performance of broilers through its negative effects on intestinal development and duodenal activity of respiratory chain complexes. Betaine could have a protective effect on mitochondrial function in the tissues of broiler chickens.
The spherical interpolation method of source localization

A closed-form least squares approximate maximum likelihood method for localization of broad-band emitters from time-difference-of-arrival (TDOA) measurements, called the spherical interpolation (SI) method, is presented. The localization formula is derived from least squares "equation-error" minimization. Computer simulation results show that the SI method has variance approaching the Cramer-Rap lower bound.

Design and Implement of Multi-Antennas for High Data Rate Communication

In this paper, it tries from experimental measurements to derive the required minimum antenna isolation and from using this minimum antenna isolation to have the MIMO to execute at its utmost efficiency. The issue of the minimum antenna isolation is actually the problem of pursuing the possible antenna module area of a multi-antenna system. As smaller size communication system is explored in real life the request of small size communication system has been discussed and many systems have been developed. To verify the feasibility of designing a multi-antenna and high throughput system is through the adopt of many MIMO technique implemented IEEE 802.11n 2x2 products to verify whether its throughput can be doubled. In this paper we integrate 4 2x2 AP antenna sets and under the operation of 8 antennas to attain the 1200 Mbps PHY rate through proper selection and design of available antennas, for 1200 Mbps PHY rate it is equivalently to have more then 600 Mbps throughput and with this implementation it is enable to prove the feasibility of the designed system.
Residual Force Method for damage identification in a laminated composite plate with different boundary conditions

The strongest point about damage identification based on the dynamic measurements, is the ability perform structural health evaluation globally. Researchers in the last few years payed more attention to damage indicators based on modal analysis using either frequencies, mode shapes, or Frequency Response Functions (FRFs). This paper presents a new application of damage identification in a cross-ply (0°/90°/0°) laminated composite plate based on Force Residual Method (FRM) damage indicator. Considering single and multiple damages with different damage levels. As well as investigating the SSSS and CCCC boundary conditions effect on the estimation accuracy. Moreover, a white Gaussian noise is introduced to test the challenge the technique. The results show that the suggested FRM indicator provides accurate results under different boundary conditions. Favouring the SSSS boundary condition than the CCCC for 3% noise.
