Herein we report the fabrication of an advanced sensor for the detection of hydrogen sulfide (H 2 S) at room temperature, using thin films of rare‐earth metal (RE)‐based metal–organic framework (MOF) with underlying fcu topology. This unique MOF‐based sensor is made via the in situ growth of fumarate‐based fcu ‐MOF (fum‐ fcu ‐MOF) thin film on a capacitive interdigitated electrode. The sensor showed a remarkable detection sensitivity for H 2 S at concentrations down to 100 ppb, with the lower detection limit around 5 ppb. The fum‐ fcu ‐MOF sensor exhibits a highly desirable detection selectivity towards H 2 S vs. CH 4 , NO 2 , H 2 , and C 7 H 8 as well as an outstanding H 2 S sensing stability as compared to other reported MOFs.

This paper introduces an attitude control technique for a quadrotor aircraft. Considering that the non-linear characteristics of the aircraft makes it difficult to stabilize, a quadrotor controlled with an adaptive algorithm. Accordingly, we proposed a quadrotor application with backstepping based on the Lyapunov function. Furthermore, we designed a separate actuator control to be mounted on the aircraft for the control of the quadrotor. This approach is often used in industrial equipments. In particular, the limited pole placement (LPP) method is applied to design the controller considering the characteristics of the actuator. The representative simulation results are presented and discussed. © 2015 The Institute of Electrical Engineers of Japan.

Today's embedded systems often do not operate individually anymore. Instead, they form so called cyber-physical systems, where the overall functionality is provided by the collaboration of systems. Consequently, the design of this collaboration is an important activity during development and strongly affects system quality. In previous work, we presented a catalog of reusable messagebased real-time coordination patterns to avoid manual creation of new and, thus, error-prone designs. In this paper, we present an implementation of this catalog by a library in the Modelica language and an appropriate development process. The library stores ready to reuse solutions for common coordination activities and, thus, increases efficiency and effectiveness for use. Furthermore, the use of Modelica enables early holistic simulation of cyber-physical systems including feedback controllers and message-based coordination. We illustrate the library with examples from an autonomous railway vehicle and present an early evaluation. Copyright © 2014 ICST.

Lab-on-CMOS chips (LOCMOS) are sophisticated miniaturized analysis tools based on integrated circuit (IC) microchips performing various laboratory functions. We have developed a low temperature co-fired ceramic (LTCC) package for a LOCMOS application regarding cytotoxicity assessment of nanomaterials. The LTCC packaged capacitance sensor chip is designed for long-term cell viability monitoring during nanoparticle exposure. The introduced LTCC package utilizes the flip chip bonding technique, and it is biocompatible as well as able to withstand the environmental conditions required to maintain mammalian cell culture directly on the surface of a complementary metal oxide semiconductor (CMOS) integrated circuit.

IEEE International Conference on Robotics and Automation (ICRA)

作者： Jin Han Lee Sehyung Lee Guoxuan Zhang Jongwoo Lim Wan Kyun Chung Il Hong Suh Department of Electronics and Computer Engineering Hanyang University Seoul Korea Princeton University New Jersey United States Information Systems Technology and Design Pillar Singapore University of Technology and Design Singapore Division of Computer Science and Engineering Hanyang University Seoul Korea Department of Mechanical Engineering Pohang University of Science and Technology (POSTECH) Pohang Korea

In this paper, we propose a visual place recognition algorithm which uses only straight line features in challenging outdoor environments. Compared to point features used in most existing place recognition methods, line features are easily found in man-made environments and more robust to environmental changes such as illumination, viewing direction, or occlusion because they are more likely to be extracted from structures. Candidate matches are found using a vocabulary tree and their geometric consistency is verified by a motion estimation algorithm using line segments. The proposed algorithm operates in real-time, and it is tested with a challenging real-world dataset with more than 10,000 database images acquired in urban driving scenarios.

Using 28nm test chips, we derive signatures for early-life failures (ELF) in both high-K/metal-gate transistors and ultra low-K inter-metal dielectrics. We also demonstrate that the derived ELF signatures can be successfully detected using a clock control technique. Our results can be utilized to overcome scaled-CMOS reliability challenges in several ways: 1. Low-cost ELF detection during on-line operation of robust systems without requiring expensive redundancy-based error detection techniques;2. Effective ELF screening during production test while reducing stress time and/or stress levels associated with stress tests such as burn-in.

Differential Power Analysis (DPA) attack for smart card,ASIC or micro controller based on crypto-systems havebeen demonstrated by several authors. Masking is avery well known approach as a DPA *** to cascading architecture of masked multiplier,the existing masking schemes increase timing and areacomplexity. Balanced masked architecture brings poorsecurity guaranty. In this paper, we propose a maskedmultiplier which reduces path delay as compared to theexisting ones in the literature. The proposed maskedS-box has two level of area optimization. One is avoidingtransformation cost and other is using masked bits insharing mode. We explore security issues in the contextof first-order and second-order DPA attacks. We havedemonstrated that our approach indeed prevents the firstorder DPA attack of the Rijndael circuit implementedon FPGA. The proposed masked AES S-box is the mostcompact one (in terms of area and path delay) as well assecure in the context of first order DPA attack.
