We first introduce the notation of intuitionistic random normed spaces. Then, by virtue of this notation, we study the stability of a cubic functional equation in the setting of these spaces under arbitrary triangle norms. Furthermore, we present the interdisciplinary relation among the theory of random spaces, the theory of intuitionistic spaces, and the theory of functional equations. 展开更多

Objective: We introduce Utena’s Brief Objective Measures of 4 Axes for Psychic Function and Energy (UBOM-4), a new brief test battery for evaluating psychic function concerning intellect, emotion, volition, and imagination. To date, insufficient general population data on the UBOM have been collected. This study aimed to establish the normative values for the general population in UBOM-4 and examine the effects of age, sex, and mental health status on the values. Methods: The General Health Questionnaire, 12-item version (GHQ-12) and UBOM-4 were administered to 149 individuals working in or attending professional schools or universities (73 males, 76 females;age: 19 - 65 years). Participants were classified as healthy based on their GHQ-12 responses and psychiatrist interviews. Results: UBOM-4 measures (mean ± SD) were: pulse rate difference (PRD or UBOM-pulse), &minus;0.72 ± 4.31 beats/min;ruler catching time (RCT or UBOM-ruler), 18.42 ± 3.73 cm;degree of randomness (DOR or UBOM-random), 0.94 ± 0.18;mean randomizing time (MRT or UBOM-time), 0.60 ± 0.31 sec. The Baum Test drawings were classified as usual (86%) and unusual patterns (14%). Sex effects were observed for RCT (UBOM-ruler) and DOR (UBOM-random), but not for PRD (UBOM-pulse) and MRT (UBOM-time). Therefore, the normative values for RCT (UBOM-ruler) (males: 17.37 ± 3.25 cm;females: 19.42 ± 3.90 cm) and DOR (UBOM-random) (males: 0.92 ± 0.18;females: 0.95 ± 0.18) should be differentiated by sex. The patterns of the Baum Test drawings were affected by age, with individuals over 51 years showing the unusual pattern more frequently (42%). Discussion: Compared to previous results for healthy individuals, the present results were similar for RCT (UBOM-ruler), DOR (UBOM-random), MRT (UBOM-time), and the drawing pattern, but different for PRD (UBOM-pulse). This difference is probably because PRD is sensitive to test situation habituation, sex of examiner, order of subtests, etc. Thus, PRD (UBOM-pulse) should be measured after the subject-examiner relationship stabilizes. Conclusion: Our results suggest that UBOM-4 can be widely used in clinical settings, utilizing the present results as a reference. 展开更多

It follows from the analysis of artillery fire errors that approximately two-thirds of the inaccuracy of indirect artillery fire is caused by inaccuracies in the determination of the meteo parameters included in fire error budget model.Trajectories calculated under non-standard conditions are considered to be perturbed.The tools utilized for the analysis of perturbed trajectories are weighting factor functions(WFFs)which are a special kind of sensitivity functions.WFFs are used for calculation of meteo ballistic elements B(ballistic wind w B,densityρB,virtual temperatureτB,pressure p B)as well.We have found that the existing theory of WFF calculation has several significant shortcomings.The aim of the article is to present a new,improved theory of generalized WFFs that eliminates the deficiencies found.Using this theory will improve methods for designing firing tables,fire control systems algorithms,and meteo message generation algorithms. 展开更多

This research proposes a novel three-dimensional gravity inversion based on sparse recovery in compress sensing. Zero norm is selected as the objective function, which is then iteratively solved by the approximate zero norm solution. The inversion approach mainly employs forward modeling; a depth weight function is introduced into the objective function of the zero norms. Sparse inversion results are obtained by the corresponding optimal mathematical method. To achieve the practical geophysical and geological significance of the results, penalty function is applied to constrain the density values. Results obtained by proposed provide clear boundary depth and density contrast distribution information. The method's accuracy, validity, and reliability are verified by comparing its results with those of synthetic models. To further explain its reliability, a practical gravity data is obtained for a region in Texas, USA is applied. Inversion results for this region are compared with those of previous studies, including a research of logging data in the same area. The depth of salt dome obtained by the inversion method is 4.2 km, which is in good agreement with the 4.4 km value from the logging data. From this, the practicality of the inversion method is also validated. 展开更多

For 0 p, q ≤ ∞ and a normal weight φ, the mixed norm space Hp,q, φ(B) consists of all functions f in H(B) for which the mixed norm p,q, φ ∞. In this article, we obtain some characterizations in terms of radial, tangential, and partial derivative norms in Hp,q, φ(B). The parallel results for the Bloch-type space are also obtained. As an application, the analogous problems for polyharmonic functions are discussed. 展开更多
