In order to detect and isolate orbiting satellite actuator faults, a decoupling parity space method was extended. The decoupling parity vector was obtained using this method by singular value decomposition. Sometimes this vector may not exist, then by singular value substitution or generalized Eigen value method was used for solving the optimal approximation. The vector can easily make satellite actuator fault detected and isolated. The simulation results showed the effectiveness of the proposed algorithm.

Retail Banking (BPR) in Jetis Ponorogo has interest in its business survival partly because of the high loyalty of its customers. Therefore, it is essential to know what factors influence the customer’s loyalty. The appropriate method for addressing the above-mentioned problem is factor analysis. Data collected from a sample of 155 respondents and there are 12 variables used in this study. The results are from 12 variables, all of them are usable and grouped into five new factor based on eigen value more than 1 (> = 1). The five factors are: Humane Products Factor has eigen value of 2,597 with variant percentage of 21,643%; Trust Factor has eigen value of 2,096 with variant percentage of 17,463%; Sincerity Factor has eigen value of 1,536 with variant percentage of 12,797%; Hospitality Factor has eigen value of 1,261 with variant percentage of 10,506%; Professionalism Factor has eigen value of 1,067 with variant percentage of 8,888%. From correlation matrix, we get value from Bartlett’s Test of Sphericity (BTS) of 433,290, which suggest that on correlation matrix there are correlation between factors supported by Kaiser-Meyer-Olkin (KMO) value of 0,606 and variant cumulative value of 71,298%.Based on the results, it is suggested that it would be better for the company to develop some humane product factor analyzed in this study because it is the predominant factor in affecting the customers’ loyalty. The customers’ loyalty is an important factor in guarantee the survival of Retail Banking (BPR) in Jetis Ponorogo.

An enhanced two-dimensional direction of arrival (2D-DOA) estimation algorithm for large spacing three-parallel uniform linear arrays (ULAs) is proposed in this paper. Firstly, we use the propagator method (PM) to get the highly accurate but ambiguous estimation of directional cosine. Then, we use the relationship between the directional cosine to eliminate the ambiguity. This algorithm not only can make use of the elements of the three-parallel ULAs but also can utilize the connection between directional cosine to improve the estimation accuracy. Besides, it has satisfied estimation performance when the elevation angle is between 70° and 90° and it can automatically pair the estimated azimuth and elevation angles. Furthermore, it has low complexity without using any eigen value decomposition (EVD) or singular value decompostion (SVD) to the covariance matrix. Simulation results demonstrate the effectiveness of our proposed algorithm.
