This paper presents the design, fabrication and measurement of a novel low-profile reconfigurable absorber based on split ring resonator (SRR). The unit cell of the absorber consists of a SRR loaded with resistors and PIN diodes, and two rings as bias circuit. The simulation and measurement results show that by forwardly or reversely biasing the diodes so as to change the resonate modes, the absorber can be dynamically switched to operate in two adjacent frequency bands. A reconfigurable frequency ratio (fHcenter / fLcenter) of over 1.7 can be achieved with the total thickness less than 1/4 wavelength (0.096-0.217 λ).

A wideband 2-3 GHz three-stage low noise amplifier (LNA) featuring current reuse, cascaded L-match input network, and multiple gated transistors method (MGTR) is designed in 0.18-μm CMOS technology. The current-reused topology is adopted to fulfill low power consumption, meanwhile, high gain and low noise are obtained. The cascaded L-match input network is used to enhance the input matching bandwidth. The MGTR is utilized to improve the linearity performance. Post-layout simulated results present a maximum power gain of 28.7 dB, a good input matching across 1.8-6.5 GHz and a high third-order input intercept point (IIP3) of-10.4 dBm. A noise figure (NF) of 3.1-3.3 dB is achieved within 2-3 GHz with a power dissipation of 6.2 mA from a 3 V power supply.

A new approach for designing a parallel coupled-line coupler with controllable bandwidth is presented. The proposed circuit consists of one coupled-line section and four open- or short-circuited stubs tapped at the ends of coupled lines. The adjustable range of fractional bandwidth is from 7% to 45% controlled by adjusting the impedance of stubs. An experiment coupler operating at 2.5 GHz was fabricated for demonstration with a bandwidth of 17.6%.

This paper presents a wide bandwidth power divider using Stepped-Impedance Resonator (SIR) impedance matching structure. The SIR structure with a short-end stub is proposed to obtain matching to separated modes thus wide bandwidth response is achieved. There are two resistor and a capacitor in series instead of single resistor added between two output ports to improve the isolation. An experimental wide band power divider is implemented which achieve the bandwidth of 103% range from 0.98 GHz to 3.55 GHz with 10 dB return loss, the magnitude and phase differences of this power divider are 0.4dB and 2±1° near the center frequency, respectively.

Recent studies show that the wireless technology could resolve the oversubscription issue in wireless data center networks (WDCNs). However, these works only focus on transmitting traffic flows at the top-of-rack (ToR) switch. In this paper, we propose a deadline-aware rate control scheme (DRCS) that detects the network congestion situation by considering the flow size, deadline, and the number of hops of the flows on each transmission path in WDCNs. The DRCS use the wireless link to distributes traffic among a pair of ToR switches (ToRs) to eliminate oversubscription of different layers in WDCNs. The performance of analytical and simulation results show that DRCS improves bandwidth utilization to reduce the oversubscription problem.

There are large amounts of interference happening to GEO satellites which cause great harm to the communication systems. GEO-location becomes a very important means to eliminate the interference in satellite monitoring work. But the uncertainty makes the suspicious area quiet large and the target hard to be found. We purposed an image recognition algorithm applied in satellite interference transmitter location. According to the simulation results, the method can reduce the search scope effectively and be very helpful for radio manage department.

This paper aims to evaluate the data storage performance with hybrid storage. In large scale smart-living applications, data require a smart and efficient manner to store daily living information. Object-based storage is a storage architecture that manages data as objects, as opposed to other storage architectures like file systems which manage data as a file hierarchy and block storage which manages data as blocks within sectors and tracks. In general, each object typically includes the data itself, a variable amount of metadata, and a globally unique identifier. Object storage seeks to enable capabilities not addressed by other storage architectures such as data replication and data distribution at object-level granularity. A distributed data store is a computer network where information is stored on more than one node, often in a replicated fashion. It is usually specifically used to refer to either a distributed database where users store information on a number of nodes, or a computer network in which users store information on a number of peer network nodes. In this paper, we focus on the performance evaluation of object data store behaviors on different types of storage. The evaluated result can provide good guideline for design of distributed object storage systems.

National Chiao Tung University is executing a large smart campus project sponsored by Ministry of Science and Technology. One of the goals is to utilize Internet of Things (IoT) technology to control electronic appliance and education devices. This talk describes a platform called IoTtalk for IOT device interaction. IoTtalk allows connection and meaningful interaction between physical IoT devices (such as a fan in a smart house). Moreover, the IoTtalk can easily accommodate cyber IoT devices such as a ball motion in animation. We show cyber and physical integration can be achieved through IoTtalk to implement Smart Campus. Specially, we show how one can use a mobile phone (physical device) to control a flower growing in animation (cyber debice) and a physical pendulum guide the swing of a cyber pendulum. Finally we show the deployment of smart electronic appliance system for a new dorm in NCTU.
