Study on the long-distance target apperception techniques for underwater vehicles

The limited physical size for autonomous underwater vehicles （AUV） or unmanned underwater vehicles （UUV） makes it difficult to acquire enough space gain for localizing long-distance targets. A new technique about long-distance target apperception with passive synthetic aperture array for underwater vehicles is presented. First, a synthetic aperture-processing algorithm based on the FFT transform in the beam space （BSSAP） is introduced. Then, the study on the flank array passive long-distance apperception techniques in the frequency scope of 11-18 kHz is implemented from the view of improving array gains, detection probability and augmenting detected range under a certain sea environment. The results show that the BSSAP algorithm can extend the aperture effectively and improve detection probability. Because of the augment of the transmission loss, the detected range has the trend of decline with the increase of frequency under the same target source level. The synthesized array could improve the space gain by nearly 7 dB and SNR is increased by about 5 dB. The detected range is enhanced to nearly 2 km under the condition of 108-118 dB of the target source level for AUV system in measurement interval of nearly 1 s.

The Role of Teachers’Apperception in Herbart’s Theory for Chinese Teaching in Shenzhen Primary Schools of China

This paper deeply analyzes the practical application of Herbart’s educational concept in contemporary education and teaching,especially its guiding significance to the primary school Chinese classroom in Shenzhen area.Herbart proposed that teachers should play a key role in students’cognitive process,that is,help students better understand and master new knowledge by combining it with existing knowledge.The survey results show that although teachers have some understanding of Herbart’s educational philosophy,it is not widely used in the concrete teaching process.However,the study also shows that there is a positive relationship between Herbart’s theory and students’academic performance,indicating that it plays an important role in improving students’interest and engagement in learning.The research also reveals the differences between educational concepts and practices,as well as the uneven distribution of educational resources,and puts forward measures to alleviate these contradictions,such as strengthening teacher training,improving teaching methods,and emphasizing moral education.At the same time,the study also highlights the critical role of teachers in promoting knowledge integration,arousing learning enthusiasm,shaping students’moral character,and promoting personal and professional growth.

On Architectural Photography

Definition of architectural photography and features of the discipline in the new era were introduced. It was proposed that consummate photography and photographic equipment were prerequisites of architectural photography, and architectural photographers had to learn architectural cultures and also intentions of architects. In addition, the ways of shooting should be determined by uses of the photos, and rich photographic languages applied to appreciate the buildings.

The Dark Reflection of Sadism within the Brilliance of the Narcissistic Persona

This double blind randomized clinical trial with 84 participants, revealed that mental patients diagnosed with narcissism, and narcissistic celebrities mirror each other’s paranoid, obsessive and histrionic symptomatology, grandiosity, manipulative charm, and inner emptiness. Elite narcissists manifested insidious sadism in the absence of depressive affect, while the narcissistic patients were differentiated by their depressive and masochistic symptomatology. Elite narcissists demonstrated advanced empathic skills, contradicting past literature. However, their empathic advantage appeared void of compassion, merely employed as a self-serving tactic to exploit, intimidate and subordinate. Both experimental narcissistic groups evidenced more prevalent psychopathology, yet, higher achievement, efficacy and ambition than their reciprocal control groups, confirming the narcissists’ finesse in concealing psychopathology under the brilliance of their pseudosuperiority. The main danger is the affinity between masochism and sadism, bonding low and high functioning narcissistic counterparts to endlessly feed from each-others’ pathology, forming dysfunctional interpersonal relationships, cults or disintegrating societies. This sadomasochistic dependency also reflects several countries’ authoritarian trends, where narcissistic constituents’ unyielding loyalty elevates idolized leaders to power, preluding the establishment of toxic tyrannical governments.

Differences between young architects'and non-architects'aesthetic evaluation of buildings

Previous studies showed significant differences between expert architects and laypeople in aesthetic evaluations of buildings.However,studies exploring the aesthetic preferences of architecture students are lacking.The present study focused on a population of students and young architects to explore the aesthetic opinion shift within architectural careers.This study was intended to be a conceptual replication of the study of Brown and Gifford(2001)in a Central European context.A total of 109 participants(21-28 years old)evaluated 40 randomized pictures of houses to detect whether non-architecture undergraduates and fresh graduates of architecture would express different aesthetic preferences compared with their peers from the general population.The study also examined whether laypersons can predict the preferences of architects,and vice versa.Results show a trend that is contrary to the original research,that is,young architects and laypeople did not significantly differ in their aesthetic evaluations of the given stimuli.Analyses revealed high prediction ability in young architects and their non-architect peers.Moreover,the existing professional experience of young architects had no influence on the accuracy of their estimations.Findings suggest that the professional shift in architects'expertise is obscured at an early career stage,as revealed in their aesthetic preferences.
