Auralization of electric vehicle's interior noise SEA simulation

Statistical Energy Analysis (SEA) has become an essential step to minimize the vehicle interior noise level. The outcome of SEA is typically 1/3 octave spectrum, and consequently it is difficult to understand the subjective effect of interior noise. This study investigated two approaches to achieve the binaural synthesis of SEA results. One is directly from the SEA 1/3 octave result and the measured coherence function. The other makes use of Source Path Contribution (SPC) to estimate the time signals on the exterior panels and subsequently applies the SEA results as a set of Finite Impulse Response (FIR) functions. Both approaches seem to result in realistic binaural signals as well as the correctly scaled sound pressure levels at the receivers. The one using SPC results can generate the input data for an NVH driving simulator by decomposing the harmonics and the masking noises. This means that the SEA result can be experienced by driving the simulated vehicle freely.

FEATURES OF RADIATION THERAPY IN PATIENTS WITH BRAIN METASTASES

Цель лечения метазтазов в головном мозге-предотвратить смерть пациента от внутричерепного прогрессирования заболевания, снизить неврологическую симптоматику или предотвратить ее возникновение, сохранив качество жизни пациента в максимально возможные сроки. Субъективный эффект после лучевой терапии оценивался у 20 пациентов в течение 30 дней после окончания лучевой терапии-уменьшение неврологической симптоматики, уменьшение головной боли. Родственники 2-х пациентов получили 50 баллов в дозе СОД-15гр по шкале Красновского, отказались от специального лечения и выписались из больницы. The aim of MM treatment is to prevent the death of the patient from the intracranial progression of the disease, reduce neurological symptoms or prevent its occurrence with the preservation of the quality of life of the patient as soon as possible. Subjective effect after radiation therapy 20 patients within 30 days after the end of radiation therapy - the reduction of neurological symptoms, reduction of headache were evaluated. Relatives of 2 patients were discharged from the hospital with the refusal of special treatment at a dose of SOD-15gr on the Krasnovsky scale.

Diagnostic Support System for the Detection of Attention Deficit Hyperactivity Disorder Using EOG Signals

Although Attention Deficit Hyperactivity Disorder (ADHD) is a common childhood disease, objective diagnostic methods are insufficient still. Current diagnostic methods include the subjective influence of the evaluator. In this context, in our study, we aimed to minimize the subjective effect of the evaluator with the objective diagnosis support system for ADHD.In our study, a visual stimulus follow-up test developed by us was applied to the patient with ADHD and healthy individuals, and electrooculogram (EOG) signals were recorded simultaneously. With the features extracted from EOG signals, Artificial Neural Networks (ANN) were used for the classification study of patients and healthy individuals, and it was determined that the classification of ADHD and healthy group could be distinguished by 81.76% performance. Thus, the outcomes that will contribute to the objective diagnosis of ADHD have been presented. The results are remarkable and important findings have been obtained that will contribute to the literature.

An Image Sharpness Enhancement Algorithm Based on Green Function

The traditional image sharpness enhancement algorithm faces several defects, namely, the lack of details, and the poor subjective effect. To solve these defects, this paper proposes an image sharpness enhancement algorithm based on the Green function. Specifically, the Retinex model was employed to ensure that the enhanced image has outstanding details, and the Poisson’s equation was solved to maintain the consistency between the enhanced image and the original image in the gradient domain. Then, adaptive brightness mapping was carried out to determine the boundary conditions suitable for display, and the boundary of the region was sampled to reduce the complexity of our algorithm. Experimental results show that our algorithm improved the contrast and sharpness of images from the levels of contrastive image enhancement algorithms.

Subjective Effects of Sound Absorption and Investigation of Reverberation Times in Modern Japanese Dwellings

This study aimed to reveal the influence of sound absorption in general dwellings on the subjective evaluation of acoustics. First, a subjective experiment was conducted using a full-scale room model. The results indicate that the feelings of silence and serenity can be experienced at absorption coefficients above 0.17, particularly above 0.25. Additionally, we used the recorded binaural sounds for a subjective test instead of using a full-scale room model. This trial showed that the reverberance, feeling of silence, and feeling of serenity can also be evaluated using a headphone listening test. We also measured the reverberation times and recorded the sound environments in three bedrooms, three living and dining (LD) rooms, and three child rooms in modern Japanese dwellings. The average absorption coefficients of the LD and child rooms were lower than 0.17, in the range of 500 Hz to 4 kHz. Therefore, we analyzed the subjective effect of absorption through a psychological test using binaural recorded sounds. The bedrooms with absorption coefficients of 0.18–0.23 were significantly less reverberant, quieter, and more serene than the other rooms.

Widersprüchliche Adoleszenz

Contradictions of Adolescence. Narcissism and Triangulation in Postfordism Based on the actuality of conservative values, aspirations for security and for adjustment and status maintenance among (post-)adolescents, the article examines possible reasons for the failure of educating for more democracy, social competences, and tolerance. It is the latent messages and general conditions of socialization in postfordism, that neutralize or even thwart the pedagogical efforts. To investigate the subjective effect of this hidden curriculum, we recommend making use of the quite unattended hermeneutic adolescence research. For that purpose, the concept of the moratorium is extended by its sociopsychological dimension. Narcissism and Triangulation as developmental psychological concepts proved particularly helpful in this case. Contradictory normative requirements in adolescence socialization attack the already labile narcissistic balance as well as the triangulation of youths.
