MEMS based 6 degrees-of-freedom parallel kinematic precision micro manipulator

A design is presented for a 6 Degree-of-freedom parallel kinematic precision micro manipulator comprising 3 translations of 20 μm stroke, and three small correction rotation strokes of 5°. The elastic deformations of the manipulator have been optimized for minimal elastic energy storage at a large guiding stiffness. The parallel kinematics facilitates 6 electrostatic lateral comb-drive actuators to be made in-plane of the wafer, using a mechanism to direct the motion to out-of-plane to obtain 6 DOF. One single technology can be used to manufacture the actuators and mechanisms. The fabrication involves deep reactive ion etching with a back-etch release process, offering great design freedom, resulting in a compact design.
Continuous Flow vs. Static Chamber μPCR Devices on Flexible Polymeric Substrates

Two types of μPCR devices, a continuous flow and a static chamber device, fabricated on flexible polymeric substrates are compared in the current computational study. Laminar flow, heat transfer in both solid and fluid, mass conservation of species, and reaction kinetics of PCR are coupled using COMSOL. The comparison is performed under same conditions; same material stack (based on flexible polymeric films with integrated microheaters), same species initial concentrations, amplification of the same volume of fluid sample, and implementation of the same PCR protocol. Performance is quantified in terms of DNA amplification, energy consumption, and total operating time. The calculations show that the efficiency of DNA amplification is higher in the continuous flow device. However, the continuous flow device requires (~6 times) greater energy consumption which is justified by the smaller thermal mass of the static chamber device. As regards the speed, the total time required for the static chamber μPCR is comparable to the time for the continuous flow μPCR.

Analytical investigation of turbines with adjustable stator blades and effect of these turbines on jet-engine performance

Adjustable-stator turbines are applied to turbojet engines and probable performance is compared with conventional engines with and without variable-area exhaust nozzles. Variation in stator-exit angle and exhaust area was not excessive for wide ranges of engine output. Variation in turbine efficiency for contemporary turbines equipped with adjustable stators was small. Improvements from 4.5 to 17 percent in over-all engine specific fuel consumption over conventional engines and from 2 to 8.5 percent over engines equipped with only adjustable-area exhaust nozzles were obtained at 60-percent rated power with adjustable-stator turbines and variable-area exhaust nozzles. The improvements depend on design parameters.
Knowledge, Attitude and Associated Factors towards Safe Abortion among Private College Female Students of Gondar town, northwest Ethiopia: A cross sectional study

Background: Unwanted pregnancies in youths and complications of induced abortions are an important health problem. Inadequate knowledge, unfavorable attitude towards safe abortion results in unsafe abortion. Most women die because of complications arising from unsafe abortion in developing countries are likely to have had little knowledge. Studies on knowledge, attitude and associated factors towards safe abortion among private college students are limited. Therefore, the aim of this study was to assess knowledge, attitude and associated factors towards safe abortion among private college female students in Gondar town, northwest EthiopiaMethods: An institution based cross-sectional study was conducted from April 30, 2019 to May 30, 2019 among private college students in Gondar town. Data were collected from 633female students using self-administered questionnaires by simple random sampling technique. Bivariable and multivariable logistic regression analysis was performed to identify association of dependent and independent variables using SPSS version 20.Result: A total of 633 respondents participated in this study with the response rate of 97.7%. Regarding the overall knowledge, 433(68.4%) of students had good knowledge towards safe abortion. Age (AOR= 2.81, 95% CI: 1.13, 7.47), residence (AOR=2.33, 95% CI: 1.22, 4.46), family education (AOR=3.29, 95% CI: 1.22, 6.46) and ever heard about safe abortion, (AOR=4.31, 95% CI: 1.79, 10.33) were factors associated with knowledge of students on safe abortion. Regarding attitude, 361 (57%) of students had favorable attitude towards safe abortion. Age (AOR=2.62, 95% CI: 1.70, 4.04) and residents (AOR=1.50, 95% CI: 1.04, 2.17) were factors significantly associated with attitude towards safe abortion.Conclusion: More than half of the participants have good knowledge and attitude towards safe abortion but still significant proportion of students have poor knowledge and unfavorable attitude. Information, Education and Communications programs on youth reproductive health should be provided to address topics on safe abortion for students. Forums and panel discussions on safe abortion need to be undertaken especially, among youths and students who came from rural area.
Effect of uncontrolled type-2 diabetes mellitus on the periodontal status of Saudi Arabian adults: A case-control study

Background The relationship between uncontrolled type-2 diabetes mellitus (T2DM) and periodontitis have been investigated among people from different nations. But, the current report is first from Saudi Arabia that utilized the gold standard measures to study the effect of uncontrolled T2DM on the periodontal status of ethnically similar Arab adults. Methods A case-control study was conducted, wherein cases were adults with clinically diagnosed periodontitis (clinical-attachment-loss ≥ 1 mm). Concurrent controls were recruited from the same dental facility; matched with age, sex, and location. Uncontrolled T2DM was recorded using HbA1c readings; and other health conditions including hypertension, epilepsy, bronchitis, thyroid disorders, and arthritis were retrieved from the participant’s medical records. Data on tobacco consumption and related products (smoking, khat/qat, sheesha, shammah) was gathered using a self-perceived questionnaire. Frequencies, percentages, p-values, crude and adjusted odds ratios (OR) with 95% confidence intervals were computed. Results Overall sample comprised of 166 cases and 332 controls with a mean age of 37.5 years. Multivariate analysis indicated uncontrolled T2DM as an important predictor for periodontitis among Saudi Arabian adults, and they had nearly three times greater odds (OR: 2.779; 95% CI: 1.425–5.419; p = 0.003) of being diagnosed with periodontitis in contrast to non-diabetics. Secondary findings revealed that cigarette ever-users were 2 times more likely to be suffering from periodontitis than never-users, and those brushing once per day or less had 5 times greater odds of developing periodontitis as compared to those brushing twice daily. Conclusion To conclude, the current case-control study is the first from Saudi Arabia to indicate that increased HbA1c level significantly effects periodontal status of Arab adults. An awareness of this association among health care providers and patients will contribute towards prevention of periodontitis in Saudi Arabia.

Angular Deviation and Its Effect on Hud-Equipped Aircraft Weapons Sighting Accuracy.

Abstract : At present, all forward windscreens (or canopies) installed on Hud-equipped aircraft are measured to determine their angular deviation, or induced aiming error. Standards have been set to accept only those transparencies which cause little aiming error, and at least one aircraft HUD fire control computer is provided with a means to compensate for the remaining error. This report is a summary of several of the multitudinous methods used to measure angular deviation for most HUD-equipped aircraft, with an explanation of the comparative accuracy of each method when applied to weapons aiming at operational sighting ranges. The advantages and disadvantages of each quality control system are discussed, and an attempt is made to reconcile the values of each system for sighting accuracy comparisons. A recommendation is made for a standardized method of measurement which is relatively error free, and best relates to operational use of the aircraft. (Author)

A feasibility study of broadband low–noise amplifiers with multiple amplification paths for radio astronomy

Multipath ampli er theory In this thesis it is proven that the theoretical minimum noise measure of a multipath ampli er (an ampli er which has multiple parallel ampli ers) is achieved by using the optimum source impedance for the ampli er and the optimum gain for each ampli cation path. This optimum source impedance and gain can be calculated by using the optimum-loaded input network, i.e. by replacing each ampli er with its optimum source impedance. The resulting noise measure is the same as the minimum noise measure of the ampli ers used in the ampli cation paths. Whereas single-path ampli ers can achieve this minimum noise measure over narrow bandwidths, multipath ampli ers are theoretically able to achieve the minimum noise measure over very broad bandwidths. The theory is demonstrated by applying it to distributed ampli ers. In an ideal distributed ampli er, the magnitude of the optimum gain of the ampli cation paths decreases and the phase delay increases the farther the stage is from the input, with the decrease in gain being faster for higher frequencies. The challenge in designing broadband, low-noise, distributed ampli ers is to achieve optimum gain matching over broad bandwidths. Multipath ampli er design procedure Based on the theory, a three step design and optimisation procedure is introduced. Firstly, unconditionally stable ampli cation paths are designed to have small minimum noise measures, then an input network is designed for optimum source impedance matching and lastly an output network is designed for gain matching. Multipath ampli er prototype The theory and design procedure is demonstrated by optimising a 0.5-2 GHz distributed ampli er. An average noise measure of 0.3 dB is achieved, which is only 0.1 dB higher than the minimum noise measure of the ampli cation stages used. This increase is mainly due to transmission line loss and gain mismatch. Radio telescope feasibility Multipath ampli ers break the trade-o between noise temperature, bandwidth and source termination that a single-path ampli er has, because they have much more design freedom when designing the input network. In general, the more paths, the larger the low-noise bandwidth, but the larger and more complex the ampli er. Roughly two to three ampli cation paths are required per octave of bandwidth for LNAs around 1 GHz. When the bandwidth is very narrow, a single path is su cient. Multipath ampli ers have similar trade-o s between linearity and power consumption, between noise temperature and noise resistance, and between noise temperature and size to a single-path ampli er. Multipath ampli ers are therefore a feasible alternative for use in radio telescopes. Key terms: Multipath, low-noise, broadband, distributed ampli er, minimum noise measure, radio telescope receiver.

Finite Element Analysis of a Highly Flexible Flapping Wing

Abstract : Small unmanned aerial systems are being designed to emulate the flapping kinematics of insects and birds which show superior control in slow speed regimes compared to fixed wing or rotorcraft aircraft. The flight of flapping wing vehicles is characterized by aeroelastic effects. Most research has been dedicated towards understanding the aerodynamic side of the aeroelastic response with minimal effort spent towards validating the structural response. A finite element model of a wing from a commercial flapping wing vehicle was created to validate the structural response. Vacuum testing allowed the isolation of the inertial response for a direct comparison to the finite element model. Wing tip displacement amplitude was matched to within 8%. The membrane kinematics of the finite element model were similar to the vacuum test article but overall membrane deflections predicted by the finite element solver were less than observed deflections seen in the vacuum. This research shows that significant focus must be placed on validating the structural side of a flexible structure in order to correctly model the complete aeroelastic response.
Single frame infrared small target detection based on local gradient and directional curvature

Infrared (IR) small target detection in a single frame is a challenging task due to the lack of texture and color information and the interference of background clutters. In light of the two-dimensional Gaussian-like shape of IR small target, two properties from the perspective of local gradient and directional curvature (LGDC) are characterized. Specifically speaking, the local gradients in four quadrants as well as the curvatures from four directions should distribute in a regular way in the target region. Therefore, an LGDC map is computed from the input IR image so that the contrast between target and background can be greatly improved. By this means, we are able to extract the IR small target by a simple threshold related to the mean and standard deviation values of the LGDC map. Experiments implemented on real IR images verify that the proposed method can achieve satisfactory performance in terms of local contrast enhancement and background clutter suppression.
