This work proposes a framework to provide emergency navigation for people within flooding events. Real-time data from weather stations are downloaded for the flooding simulation in our framework. Sensors are disposed along the river, and the collected sensor data can be used to update our simulation results to provide more accurate estimation of flooding events. After flooding models are constructed, this work further includes and modifies the Dijkstra algorithm for the navigation. Our navigation algorithm dynamically considers the traveling speed of users, the real-time flooding data, and the estimation of flooding to provide the best route which is not only the shortest path to destinations but also relatively safe. In our prototype implementation, the map of Manado City is included in our experiments, and the traces of the real flooding data of Manado City are also included as the input of our experiments. The experimental results show that our framework can immediately provide alarm and navigation when a node in the map is prone to be flooded, and the provided routes can avoid flooding nodes in the map.

We propose a High-Definition Multimedia Interface (HDMI) video scaling system based on an all-programmable SoC, which can be used in any image processing system requiring a two-dimensional (2D) interpolation accelerator. This structure work on a platform-based SoC environment. By the AXI Video Direct Memory Access (AXI VDMA), video data are directly transferred between DDR3 memory and the built-in FPGA where the proposed buffering scheme and interpolation accelerator are implemented. We store video data in the DDR3 memory and the interpolation accelerator performs real-time video scaling. An experiment with HDMI video input from a Microsoft Windows PC and HDMI video output to another display proves the effectiveness of the real-time video scaling.

Location based service relies on precise outdoor and indoor positioning technologies. Intuitively, indoor positioning is more difficult than outdoor positioning because of complicated environment. Fingerprint is a technique proposed to sketch the characteristic of every indoor location by adopting time-consuming measurements in offline phase. To minimize overhead, virtual fingerprint construction scheme (VFCS) with smart antenna system (SAS) has been proposed to fast construct the database based on the log-distance path loss model and interpolation scheme. Our experiments reveal that the VFCS may perform worse when the measured received signal strength levels (RSSIs) are unstable. This paper proposes a simple zone-based algorithm for VFCS to first localize potential zone and then estimate the possible location. Experimental results show that the proposed zone-based algorithm for VFCS and SAS indeed promotes the accuracy of indoor location estimation even using extrapolation scheme.

Digital signal processors (DSP) with very-longinstruction-word (VLIW)processors have been widely used incommunication systems in recent years. It is obvious that parallelism requirement are different between applications, even within an application. As a result, the scheme, which is to partition the application into several regions and assign each region with adapted parallelism, has been proposed. In this paper, we enhance the parallelism assignment stage. The aim is to tune parallelism according to the deadline (the special execution time of users). The proposed algorithm could save more energy with meeting the requirement of users. The experimental results of evaluation with CoreMarkPro benchmark suits show the expected savings of leakage energy. Compared with maximum energy mode, the execution energy could be reduced more than 40% and the execution time just increase less than 10%.

A GGNMOS transistor is used to fine-tune of its curvature compensation in high temperature. The temperature coefficient (TC) is lower than 6ppm/0C in a temperature changed from -40°C to 125°C with different corners. The supply voltage ranges from 0.65V to 2.5V, and the power consumption is 100nW with 1V supply voltage. The power supply rejection ratio (PSRR) without any filter capacitor at 100Hz is lower than -46dB.

Recently, the rapid development and application of diversified embedded systems, such as cyber-physical systems (CPSes) and Internet-of-things (IoTs), is widely observed. Because embedded systems are often powered by batteries, the energy efficiency has become a key issue in system development. As a result, various energy-efficient nonvolatile memories, such as phase-change memory (PCM) or spin-torque-transfer random-access memory (STT-RAM), have become attractive choices for the storage of data and accompanying metadata (such as the index information of data) on embedded systems. However, a write operation takes much more (7X-10X) time and energy than a read operation does on many nonvolatile memories. This makes existing dictionary structures, e.g., the well-known red-black tree or B-tree, not preferred for metadata management nonvolatile memories. Although some efficient out-place update schemes such as partial Day-Stout-Warren (pDSW) algorithm have been proposed for tree rebalancing, they could result in serious fragmentation of space usage and garbage collection overheads. In this paper, we proposed a novel approach called Graft-based Algorithm for Tree Rebalancing (GART) to efficiently rebalance search trees with reduced garbage collection overheads. Just like the pDSW algorithm, although GART algorithm does not guarantee the worst-case height og the search tree, it provides an efficient means to ensure good memory access time on tree querying in most cases.

A millimeter wave monolithic microstrip antenna, formed on the surface of conical surface using the conformal FDTD algorithm, is introduced, which design of rectangular microstrip patch cell by using the conventional microstrip feed mode. The simulation results indicate that the antenna gain is 7dB and can use multiple slices form the conformal array antenna.
