Emotion recognition behavior and performance may vary between people with major
neurodevelopmental disorders such as Autism Spectrum Disorder (ASD), Attention Deficit
Hyperactivity Disorder (ADHD) and control groups. It is crucial to identify these differences
for early diagnosis and individual treatment purposes. This study represents a
methodology by using statistical data analysis and machine learning to provide help to
psychiatrists and therapists on the diagnosis and individualized treatment of participants
with ASD and ADHD. In this paper we propose an emotion recognition experiment
environment and collect eye tracker fixation data together with the application log data
(APL). In order to detect the diagnosis of the participant we used classification algorithms
with the Tomek links noise removing method. The highest classification accuracy results
were reported as 86.36% for ASD vs. Control, 81.82% for ADHD vs. Control and 70.83%
for ASD vs. ADHD. This study provides evidence that fixation and APL data have
distinguishing features for the diagnosis of ASD and ADHD. 相似文献

The quality and biochemical properties of honey are affected by heating or during storage period. The most important biochemical reaction that occurs in this process is the Maillard reaction. HMF (5-hydroxymethylfurfural) is one of the major intermediate products in the Maillard reaction that can lead to quality reduction in heated honey. In this study, the effect of heating on the antioxidant activity, and colour values as Maillard reaction indicators of three different botanical honeys were investigated; the HMF formation was also determined. Temperatures of 50, 70 and 80 °C were applied on the honeys between 0 and 48 h. Total phenolic content, ferric reducing/antioxidant power and scavenging of 2,2-diphenyl-1-picrylhydrazyl free radical assays are used to determine the antioxidant capacity. Results showed that the formation of HMF and the antioxidant properties of honeys were significantly increased during the heating process. Pure HMF compound also showed lower antioxidant activity. The formation of HMF has higher degree of linearity in the fit of the zero order reaction and also it was the highest in the chestnut honey. Furthermore, it was found that as the biochemical value of the honeys increased, the HMF formation decelerated. 相似文献

Diffusion of indium in In/nCdS/glass and In/nCdS/pSi structures at 350–550 °C in vacuum 1.33 × 10−1 Pa and its effect on structural, electrical, optical and photovoltaic characteristics of nCdS films, fabricated by spray pyrolysis technique and nCdS/pSi heterojunctions have been investigated. The indium-doped and undoped CdS films were characterized by X-ray diffraction (XRD), electrical and optical measurements. The concentration profiles of indium and the components of CdS films (Cd and S) in In/nCdS/pSi structures were studied using the energy dispersive X-ray fluorescence (EDXRF) analysis. The thermal annealing of In/nCdS/pSi structures is accompanied by the diffusion penetration of In through CdS film into Si substrate. At the same time, the Cd and S atoms from CdS film diffuse into Si substrate. The diffusion doping of CdS film by indium did not change the polycrystalline hexagonal structure and the energy band gap of CdS films and increased the electron concentration from 1.4 × 1013 to 1.3 × 1016 cm−3. The photovoltaic parameters and spectral responsivity of In-doped nCdS(In)/pSi(In) cells were higher than those for nCdS/pSi cells and reached the maximum values after the thermal annealing at 450 °C. The improvement of the photovoltaic parameters of nCdS(In)/pSi(In) photocells was discussed on the base of the changes introduced in the energy band diagram of nCdS/pSi heterojunction due to the indium diffusion. 相似文献

A series of five experiments provide evidence against a strategy disruption explanation (e.g., Basden, Basden, & Galloway, 1977) of the part-set cuing effect. Word-fragment cuing tests were used to gauge memory performance; subjects tried to discover each word with the help of the given letters. With the words thus probed for recall individually and in an experimenter-imposed order, the strategies in the cue and control conditions were kept constant. Yet performance was impaired when the critical fragments were preceded by relevant cues, for both studied and nonstudied words and in the case of studied words, with both intralist and extralist cues. In addition, Experiment 6 provides evidence against the increased-list-length explanation (Watkins, 1975). Presenting cues in the beginning of the test list impaired recall performance, whereas presenting the same cues in the same way at the end of the study list did not.

This paper presents two tuning algorithms for fractional-order internal model control (IMC) controllers for time delay processes. The two tuning algorithms are based on two specific closed-loop control configurations: the IMC control structure and the Smith predictor structure. In the latter, the equivalency between IMC and Smith predictor control structures is used to tune a fractional-order IMC controller as the primary controller of the Smith predictor structure. Fractional-order IMC controllers are designed in both cases in order to enhance the closed-loop performance and robustness of classical integer order IMC controllers. The tuning procedures are exemplified for both single-input-single-output as well as multivariable processes, described by first-order and second-order transfer functions with time delays. Different numerical examples are provided, including a general multivariable time delay process. Integer order IMC controllers are designed in each case, as well as fractional-order IMC controllers. The simulation results show that the proposed fractional-order IMC controller ensures an increased robustness to modelling uncertainties. Experimental results are also provided, for the design of a multivariable fractional-order IMC controller in a Smith predictor structure for a quadruple-tank system. 相似文献

Preparation and characterization of aluminum pillared K10 and KSF for adsorption of trimethoprim 总被引:1,自引:0,他引:1
Montmorillonite KSF and K10 were used as precursor materials for synthesis of aluminum pillared K10 and KSF (Al-K10 and Al-KSF) which characterized by TGA, XRD, SEM and FT-IR spectroscopic analysis. The sorption of trimethoprim (TMP) which is commonly employed as an antibiotic onto Al-K10 and Al-KSF was also investigated as a function of adsorbent dosage, solution pH, contact time and temperature. The adsorption kinetics was interpreted using pseudo-first-order, pseudo-second-order kinetic models and intraparticle diffusion model. The pseudo-second-order model provided the best correlation. Adsorption isotherm parameters were obtained from Freundlich, Langmuir and Dubinin–Radushkevich (DR) isotherm models. Adsorption of TMP onto Al-K10 and Al-KSF was physical in nature and ion-exchange mechanism for DR equation, respectively. Al-K10 exhibits higher removal capacity at lower adsorbent dosages in comparison with Al-KSF. The removal capacity was increased by increasing pH. ΔH0, ΔS0 and ΔG0 showed that adsorption of trimethoprim was endothermic, increasing randomness and not spontaneous in nature. 相似文献
