Heavy metals existing in the surface of sediments of the tidal river could be transferred into the surrounding natural and artificial biofilms, through physical, chemical, biological or their combination processes. This paper studied on the adsorption and transfer regulation of heavy metals in biofilms grown on river rocks and inert carriers in tidal rivers. The natural and artificial biofilms, and the surrounding sediments nearby were taken, among of which the heavy metals (Mn, Zn, Cu, Pb, Ni and Cd) contents were measured using ICP-AES method. The absorption of heavy metals in the biofilms and the migration characteristics of heavy metals into the biofilms were measured and analyzed. Our results showed that the contents of heavy metal in the biofilms were similar to those in the surrounding surface sediments nearby in the tidal rivers, which was probably attributed to the dynamic equilibrium between the biofilms and its surrounding surface sediment and water. The migration of heavy metals between biofilms and surface sediment through water movement in tidal river showed certain limitations for biofilms adsorption to remove heavy metals. The contents of heavy metals in biofilms were impacted by many factors, such as the biofilms characteristics, the types and forms of existing heavy metals, the contents of heavy metals in the adjacent surface sediment, the hydrological conditions, and the formation time of biofilms. This study can provide important references for the remediation of the polluted tidal rivers by using biofilms method.

Industrial designers and engineering designers: Can't we all just get along? Unfortunately, when push comes to shove, it's engineering that tends to win. How can schools better prepare industrial designers for the work force? engineering designers and industrial designers would get along much better if they shared common knowledge and common goals—long before they reached the workplace.

Previous studies have reported that postural coordination patterns change as a function of translation frequency. However, the effect of inclined support surface on postural strategy was not clear. Therefore, the purpose of this study is to investigate the influence of inclined support surface on postural strategy during platform translations. Eight healthy adults maintained their balance in stance during support surface translations in the anterior-posterior direction at two different frequencies (0.2 and 0.8[Hz]) and at three different base of support condition (LV: Level, Td: Toe down, TU: Toe Up). For the kinematic data at slow frequency, subjects rode the platform depending on the movement of platform itself, while at fast frequency subjects fixed their head and center of mass (COM) in space. For the kinetic data at slow frequency, the ankle moment amplitude is similar among all support surface conditions, while at fast frequency the ankle moment amplitude for TU is significantly larger than LV. Result shown that the effect of inclined surface on postural strategy changed according to frequency of support surface translations.

This research applied both the traditional and the fuzzy control methods for mobile satellite antenna tracking system design. Firstly, the antenna tracking and the stabilization loops were designed according to the traditional bandwidth and phase margin requirements. However, the performances would be degraded if the tacking loop gain is reduced due to parameter variations. On the other hand a Pd-type fuzzy controller was also applied for tracking loop design. It can be seen that the system performances obtained by the fuzzy controller were better for both low and high antenna tracking loop gains, and the tracking loop gain parameter variations effect can be reduced. © 2011 IEEE.

Micro Aerial Vehicles (MAVs) have gained a significant amount of research lately, with a number of universities and industry sponsors paving the way with micro flying robots to perform Intelligence, Surveillance and Reconnaissance (ISR) Missions. However, much of the work done in VTOL/Hover-Capable MAVs till date has not shown performance improvement in flight endurance and payload capacities. In this paper we introduce and detail the Energy dynamics of a novel Quad-Wing MAV (QV) design and illustrate the improvement in-flight energy consumption, directed towards higher payload capacities and longer flight times. Additionally we show that independent wing control of the QV generates all 6 degrees of Freedom (doF) flight maneuvers. By the use of passive elastic elements, we can produce resonant flapping, generating lift and further improvements in energy savings. © 2011 IEEE.

This study demonstrated a newly type technology of a wafer level packaging method for light emitting diode (LEd) with aspheric lens and microlens array using microelectromechanical systems (MEMS) technology and transfer molding process. The novel packaging structure includes two components: the silicon-based packaging substrate which is formed with arrayed reflector depression and through-hole interconnects by bulk micromachining and the optical encapsulation with lens configuration that formed by transfer molding in wafer level. By this pattern transfer process, the precise alignment between lens configuration and the reflector of silicon substrate can be achieved and batch process can be realized to reduce the costs. Beside, the packaging element can be used more applications. In the study, the pattern transfer of various lens profiles was also accomplished successfully by using silicone gel as lens mold. The brightness of the packaging elements with single aspheric lens profile and high fill factor microlens array can be increased by 26% and 16%, respectively, in comparison to the case of optical encapsulation with smooth curved surface. Furthermore, the light radiation uniformity was improved effectively through 100% fill factor microlens array. Therefore, the structure can satisfy the requirements of wafer level LEd packaging and improve the heat dissipation and light extraction efficiency. © 2011 IEEE.

This paper mainly outlines the model of the invented spherical robot using Omni wheels to drive a spherical wheel. The dynamical model is derived based on Euler Lagrange approach. Therefore, based on the derived model, the variable structure control (VSC) is presented in which the sliding mode control (SMC) is adopted to achieve a constant speed at a vertical balance altitude. Simulations of the proposed control algorithm have been conducted based on two pre-determined sliding surfaces with adjustable parameters to discuss the effective time to enter the sliding surface and the convergence.

Biological Inspiration for the design of flapping wing vehicles has been the source of numerous design efforts in the field of Micro Aerial Vehicle (MAV) development. For flapping flight in small birds and insects, high lift generation is typically a result of unsteady fluid flow phenomena. Our previous studies have conceptualized and demonstrated how a dragonfly inspired Quad-Winged Vehicle (QV) can produce higher energy efficiency and increase payload capacity on-board an MAV. The objective of this paper is to further improve on the in-flight aerodynamic efficiency of MAVs and propose improved flapping configuration and kinematics of a light weight wing to enhance lift and aerodynamic efficiency during hovering flight. This paper presents a series of experimental and computational results in the form of performance plots comparing the effects of wing orientation, flapping kinematics: frequency / amplitude and wing feathering, all of which influence the lift and drag generated by the MAV. © 2011 IEEE.
