Balancing Privacy-Utility of Differential Privacy Mechanism: A Collaborative Perspective

Differential privacy mechanism can maintain privacy-utility monotonicity. Thus, differential privacy mechanism does not obtain privacy-utility balance for numerical data. To this end, we provide privacy-utility balance of differential privacy mechanism with the collaborative perspective in this paper. First, we constructed the collaborative model achieving privacy-utility balance of differential privacy mechanism. Second, we presented the collaborative algorithm of differential privacy mechanism under our collaborative model. Third, our theoretical analysis showed that the collaborative algorithm of differential privacy mechanism could keep privacy-utility balance. Finally, our experimental results demonstrated that the collaborative differential privacy mechanism can maintain privacy-utility balance. Thus, we provide a new collaborative model to solve the privacy-utility balance problem of differential privacy mechanism. Our collaborative algorithm is easy to apply to query processing of numerical data.

Optimization of disassembly line balancing using an improved multi-objective Genetic Algorithm

Disassembly activities take place in various recovery operations including remanufacturing, recycling, and disposal. Product disassembly is an effective way to recycle waste products, and it is a necessary condition to make the product life cycle complete. According to the characteristics of the product disassembly line, based on minimizing the number of workstations and balancing the idle time in the station, the harmful index, the demand index, and the number of direction changes are proposed as new optimization objectives. So based on the analysis of the traditional genetic algorithm into the precocious phenomenon, this paper constructed the multi-objective relationship of the disassembly line balance problem. The disassembly line balance problem belongs to the NP-hard problem, and the intelligent optimization algorithm shows excellent performance in solving this problem. Considering the characteristics of the traditional method solving the multi-objective disassembly line balance problem that the solution result was single and could not meet many objectives of balance, a multi-objective improved genetic algorithm was proposed to solve the model. The algorithm speeds up the convergence speed of the algorithm. Based on the example of the basic disassembly task, by comparing with the existing single objective heuristic algorithm, the multi-objective improved genetic algorithm was verified to be effective and feasible, and it was applied to the actual disassembly example to obtain the balance optimization scheme. Two case studies are given: a disassembly process of the automobile engine and a disassembly of the computer components.

Acupuncture Application in Seconder amenorrhea Obese female Patient

Obesity is a disease caused by excessive fat storage in the body. It is an energy balance problem. Obesity can prepare the ground for many diseases. Secondary amenorrhea is the condition of not having menstruation for 6 months. In Traditional Chinese Medicine, it is thought to be caused by Qi and blood deficiency. The 43-year-old nurse applied due to obesity, inability to have menstruation, edema and nodules in goiter. TSH was 4.25, T3 2.87, T4 1.07mU/L. The 78.6 kg 150cm tall TA was 100/70 mmHg.Ten sessions of acupuncture were performed. Yin-tan, DU-20,21, LU-9, H-7, PC-6, SI-3, ST-24,25, REN-7,9, KID-3-6, SP -6.9 uterus, zero, jerome, shen-men hunger, kidney, points were pinned with disposable acupuncture needles. The patient, whose edema was resolved in the second session, started to have menstruation in the third session and lost 9kg in total. The patient had regular periods during the 1-year follow-up. TSH fell to 3.18mU/L.

Time efficiency in production is very supportive of fulfilling consumer demand. The track balance problem can be solved by taking measurements first. This measurement aims to determine the parameters that cause an imbalance in the production line. The first step that needs to be done is measuring the track balance before optimization. Rank Postional Weight is heuristic’s systematic approach method is used to measure the balance of the car CVT belt production line in a grinding machine. The measurement results show that it is not good with a smothness index of 130.48 minutes, the product produced is only 97.5% of the set target, the performance of the work station is 80.56%. Improvements in several work stations in order to improve the balance of the trajectory, namely in visual checks, smoothing surfaces and shapes, measuring products by rearranging the order.

MOTION PLANNING OF ASSISTIVE EXOSKELETON IN HUMAN’S LOCOMOTION REHABILITATION

Researches on rehabilitation exoskeleton system have bee n implementing in recent decades and have been achieving many advantages. However, most of reseaches have focused on more simplified systems such as rehabilitation exoskeleton for one or two joints or for one paralysed leg with the purpose of recovering human’s locomotion pattern. Researches on rehabilitation exoskeleton using for whole two paralysed legs are limited because of the complexity of balance issue for a combined human – exoskeleton system. Therefore, crutches are used to prevent the human from falling during human’s walking in recent researches. In order to abandon the crutches and help to recover human’s nomal walking pattern, the balance problem of combined human-exoskeleton system must be considered in control algorithm. In this paper, we build a motion path for a combined human-exoskeleton ensuring that the combined human-exoskeleton system can move in a balanced area. Our proposed paths are validated in the control algorithm for the HUALEX exoskeleton system in University of Electronic Science and Technology of China (UESTC).

KATHERINE SAXON (b. 1981)Sea Fever (2008)

This chapter discusses American composer Katherine Saxon’s Sea Fever (2008). In this piece, the musical style is straightforward, uncluttered, and accessible, with elements of neoclassicism, and the four songs are well contrasted. The second has space-time notation, but the others are written conventionally, with key and time signatures. The relationship between voice and piano is well gauged, but there may be a few balance problem for lighter voices, especially when lines are low-lying. Verbal clarity is a crucial requirement. Words and music teem with watery images, and the sonic palette of John Masefield’s resonant poetry, full of alliteration and onomatopoeia, is a gift for composers, to which Saxon responds with empathy and panache. Some very fast articulation is called for, especially in the last song. The composer’s succinct instructions for mood and character are always pertinent.
