Improvement of the fuel consumption and exhaust gases have been one of the important issues in automobile. Hybrid electric vehicles(HEVs) that have one internal combustion engine(ICE) and electric motors(EMs), can meet this requirement. To improve them simultaneously, a well-organized energy management system(EMS) should be developed. In this paper, a novel EMS considering torque control is developed, in which a function called the torque control function is introduced to control the driving mode, the target ICE torque, and the target EM torque. In addition, a sequential approximate optimization using a radial basis function network is adopted to determine the torque control function. co2 and NOxare so closely related the fuel consumption and the exhaust gases, and they are then simultaneously minimized. A multi-objective design optimization is the formulated, and the torque control function is determined with a small number of simulation runs. The worldwide harmonized light duty driving test cycle is used to examine the validity of the proposed EMS using the torque control function.

A novel amorphous silicon temporary bonding and corresponding laser assisted de-bonding technology are investigated for the improvement of 3d integration. Excellent bonding results with real device wafer with α-IGZO thin-film transistor are shown at the bonding temperature of 210℃, as well as outstanding performances for bonding strength, thermal stability, reliability and chemical resistance. Laser ablated amorphous silicon is proved stable and ultra-fast. Advantages of excellent bonding quality, lower cost and higher throughput demonstrate that this scheme can be a potential candidate in 3d integration platform.

An attractive nanoemulsion fluid system with a drop‐percolated network is depicted in the image, in which dipole–dipole interaction between phosphorylcholine groups of lecithin and methoxy end groups of poly(ethylene oxide)‐block‐poly(ϵ‐caprolactone) leads to a gel‐like rheological behavior. This intriguing emulsion system significantly enhances transdermal delivery efficiency due to its favorable attraction to the skin as well as high diffusivity of the nanoscale emulsion drops. More information can be found in the Full Paper by Y. Lee, A. Fernandez‐Nieves, J. W. Kim et al. on page 4292 ff.

Metal sheet with microhole group can be used as a sound absorption to meet the application of acoustic noise reduction. However, laser drilled thin aluminum sheet is easy to deform and to splash, as well as hole taper and consistency is difficult to be controlled. In the present work, 30 000 microholes with 100 μm diameter were fabricated on a 0.1 mm thick aluminum sheet using a 1 064 nm nanosecond laser drilling system. The effects of process parameters on the quality of drilled microholes were studied by means of microscope and surface profiler. The jump array processing method designed in this work effectively avoided the aluminum sheet deformation problem in dense microhole drilling. Furthermore, the microhole group is of good consistency, with the hole taper 0.07 and roundness error 0.05. The measured acoustical absorption coefficient of microhole group aluminum sheet is 0.79, which is effective for acoustic noise reduction. © 2016, Materials review Magazine. All right reserved.

It is commonly expected that network densification will play an important role in achieving the capacity demands of 5G communication networks. While densification is introduced to improve the spectral efficiency and area-capacity, it also results in an infrastructure that is perfectly suitable for user node (UN) positioning. However, so far this compelling opportunity has not been clearly recognized in the literature. In this paper, we therefore propose to make "always on" positioning an integral part of 5G networks such that highly accurate UN position estimates are available at any given moment but without draining the UN batteries. We furthermore propose an extended Kalman filter (EKF) that tracks the UN position based on the fusion of direction of arrival (doA) and time of arrival (ToA) estimates obtained at the access nodes (ANs) of the 5G network. Since ToA estimates are typically not useful for positioning unless the UN is synchronized with the network, we include a realistic clock model within the doA/ToA EKF. This addition makes it possible to estimate the offset of the imperfect UN clock, along with the UN position. In an extensive analysis that is based on specific 5G simulation models, we then quantify the enormous potential of high accuracy positioning in 5G networks, in general, and the proposed doA/ToA EKF, in particular. Moreover, we demonstrate that the proposed doA/ToA EKF substantially outperforms the classical doA-only EKF and is furthermore also able to handle practically extremely relevant situations where the doA-only EKF fails to position the UN.

The deployment of future 5G ultra-dense small cell networks provides unprecedented opportunities to create an advanced localization system that meets the demands of future location-based services and functionalities. In this paper, we present technical enablers for obtaining location information of user nodes (UNs) in a network-centric manner. More specifically, we focus on signal properties, access node (AN) hardware and AN deployments in the envisioned 5G systems. Moreover, we provide illustrative examples of the expected localization performance and indicate how to efficiently predict the UN location. Finally, we offer insights into the utilization of location-awareness and location prediction, and show that it provides substantial benefits compared to existing radio networks.

An ultra-fast temporary bonding and release process was investigated for the improvement of 3d integration. The bonding scheme composes of two different kinds of polymer for release layer and adhesive layer. The submicron release layer is a positive photoresist with the characteristic of high UV absorption induced into the de-bonding procedure within 20 s. In addition, the adhesive layer provides robust mechanical strength for the wafer thinning process. Based on results, this structure is a potential candidate for temporary bonding and de-bonding technique in 3d integration.

In the development of the inter-vehicle communication systems for the prevention of car crashes, it is important to know the radio propagation characteristics at blind intersections. In experiments and numerical simulations of the radio propagation, a half wavelength dipole antenna is assumed to be the wave source in many cases. However, the directivity of car antenna is changed by the effect of car body. Additionally, the directivity of car antenna is also changed by the effect of antenna position on car body. Therefore, it seems necessary to investigate radio propagation characteristics considering car antenna positions. In this paper, the effect of car antenna positions on propagation loss at different receiving height in a blind intersection for inter-vehicle communications is investigated. Here, the hybrid method using both the FdTd and ray-tracing methods is used for the radio propagation analysis.
