This paper proposes a three-dimensional mathematical model of the biomechanical interactions between backpack and bearer during load carriage. The model considers both the coupled pack motions, which follow the torso, and also the longitudinal compliance and damping in the backpack suspension. The pack interaction forces and moments, acting on the bearer, are determined from kinematic relations...

In this study, a three dimensional (3D) modeling has been built for a lithium ion battery pack using the field synergy principle to obtain a better thermal distribution. In the model, the thermal behavior of the battery pack was studied by reducing the maximum temperature, improving the temperature uniformity and considering the difference between the maximum and maximum temperature of the batt...

BACKGROUND Little is known about the association between cigarette smoking and asthma severity. We assessed smoking as a determinant of disease severity and control in a cohort of clinic-referred allergic subjects who developed new onset asthma. METHODS Allergic rhinitis subjects with no asthma (n = 371) were followed-up for 10 years and routinely examined for asthma diagnosis. In those who d...

Background: Tobacco packaging is an important form of promotion. Standardizing cigarette packages (‘plain’ packaging) represents a novel tobacco control policy. This study examined perceptions of branded and standardized cigarette packages among British youth. Methods: Seven hundred twelve youth aged 11–17 completed an online survey. Participants viewed pairs of packages altered using a 3 2 fac...

Based on a low cost multi-switched inductor balancing circuit (MSIBC), a fuzzy logic (FL) controller is proposed to improve the balancing performances of lithium-ion battery packs instead of an existing proportional-integral (PI) controller. In the proposed FL controller, a cell’s open circuit voltages (OCVs) and their differences in the pack are used as the inputs, and the output of the FL con...

The Chinese-English bilingual teaching in the circuit course is an important approach to foster innovational talents for the electronic industry in the new century. In this article, we analyze the background, applicability and feasibility of bilingual teaching in the course of circuit and the difficulties facing in the process of implementation. We explore various approaches and methods to over...

SIMD instructions are often implemented in modern multimedia oriented processors. Although SIMD instructions are useful for many digital signal processing applications, most compilers do not exploit SIMD instructions. The difficulty in the utilization of SIMD instructions stems from data parallelism in registers. In assembly code generation, the positions of data in registers must be noted. A t...
