AbstractA new interpulse frequency diverse technique is introduced for weather radar second-trip suppression and retrieval. Interpulse coding is widely used for second-trip suppression or cross-polarization isolation. Here, a new interpulse scheme is discussed, taking advantage of frequency diverse waveforms. The simulations and performance tests are evaluated, keeping in mind NASA dual-frequency, dual-polarization, Doppler radar (D3R). A new method is discussed to recover velocity and spectral width despite the incoherence in samples due to the change of frequency from pulse to pulse. This technique can recover the weather radar moments over a much higher dynamic range of the second-trip contamination than the popular interpulse phase codes, for second-trip suppression and retrieval under specific phase noise conditions. And it has a bigger recovery region of second-trip velocity if the region is drawn with increasing spectral width (compared to other interpulse codes).

Study aims to determine the results of learning to make paes proportionally through direct learningmodel approach. The study used a one shots case study design study. The subjects of the study werestudents of Adi Buana University class of 2016, amounting to 25 people. Methods of data collectionusing written tests make design and performance tests make paes on the model. The bride Yogja Putriis one of the bridal makeup styles of court the Yogjakarta. Characteristic of the bride Java princess isa form of paes on the forehead that only uses a shoot, without using prada. Making bridal paes bothsolo and Yogja, Originally using traditional methods, but as the development of science then themethod proportional to alternative making paes. Paes is a black or green forehead makeup. Paes onthe bride Yogja consists of 4 parts, namely penunggul, penyep, penitis and godeg. The purpose of thisstudy is to know the learning outcomes of making Yogja princess paes with direct learning modelproportionally, Proportional Technique is Technique of making paes which base on visualization ofbridal face that is peak of nose and corner of eye of outside. These benchmarks are used to makepenunggul, penitis, pengapit and godeg. The purpose of making paes proportionally is to ease inmaking paes for beginners, especially students. Learning outcomes make paes proportionally easierby using visualization of the bridal face as a benchmark. This is evidenced by the increase of learningoutcomes from making the design to the actual model of the cycle I average obtained by 83.3%, thesecond cycle of 89.7%, and the average III cycle obtained 95.5%.

Abstract. This project compared the relative performance of professional dancers and nondancers on the Music Apperception Test (MAT; van den Daele, 2014 ), then compared dancers’ performance on the MAT with that on the Thematic Apperception Test (TAT; Murray, 1943 ). The MAT asks respondents to “tell a story to the music” in compositions written to represent basic emotions. Dancers had significantly shorter response latency and were more fluent in storytelling than a comparison group matched for gender and age. Criterion-based evaluation of dancers’ narratives found narrative emotion consistent with music written to portray the emotion, with the majority integrating movement, sensation, and imagery. Approximately half the dancers were significantly more fluent on the MAT than the TAT, while the other half were significantly more fluent on the TAT than the MAT. Dancers who were more fluent on the MAT had a higher proportion of narratives that integrated movement and imagery compared with those more fluent on the TAT. The results were interpreted as consistent with differences observed in neurological studies of auditory and visual processing, educational studies of modality preference, and the cognitive style literature. The MAT provides an assessment tool to complement visually based performance tests in personality appraisal.
