Two types of coupled neural networks with reaction-diffusion terms are considered in this paper. In the first one, the nodes are coupled through their states. In the second one, the nodes are coupled through the spatial diffusion terms. For the former, utilizing Lyapunov functional method and pinning control technique, we obtain some sufficient conditions to guarantee that network can…

Panel discussions computing technology for autonomous driving
Autonomous driving is becoming more and more multidisciplinary. Not only vehicular technologies but also computing, networking, and data management technologies are involved in autonomous driving. Of particular interest includes the trade-off between in-vehicle computing and cloud computing to support artificial intelligence of autonomous driving. Perception and planning of autonomy requires high-performance computing while battery-driven vehicles must…
Range Enhanced Packet Classification Design on FPGA
The future of fast Internet needs powerful routers to support abundant network functionalities, such as firewall, QoS, and virtual private networks by classifying the packets into different categories based on a set of predefined rules, so-called multi-field packet classification. Traditional packet classification that considers only 5 tuple fields is not sufficient for today’s complicated network requirements. OpenFlow switch was born to…
Flowshadow: a fast path for uninterrupted packet processing in SDN switches
Updating rules in the flow tables of SDN switches are complex and time-consuming. Therefore, we propose a cache-based scheme (named FlowShadow) to improve the packet processing performance and keep continuous operating while updating rules in the flow tables. FlowShadow caches the microflows in the hash table to build a fast path for packet processing. By…
Orthogonal stacked composite M-sequence labels for quick packet routing over optical MPLS network
In this paper, we construct a composite label sets for optical multi-protocol label switching (MPLS)network. Relatively prime lengths maximal-length (M-sequence) codes are taken to compose into spectral-amplitude coding (SAC) labels. These composite M-labels possess good orthogonality and are compatible with packet labels stacking. With correlation subtraction scheme in packet routing node, local node label can…
Gain enhancement of butler matrix fed antenna array system by using planar circular EBG units
In this paper planar circular Electromagnetic Band Gap (EBG) structures have been implemented in the Butler matrix fed antenna array system to improve the radiation performance of the system. Initially a conventional 4×4 Butler matrix fed antenna array system has been designed at 14.5 GHz. Asymmetricity in the gain values of major beams of the…
CogCell: cognitive interplay between 60 GHz picocells and 2.4/5 GHz hotspots in the 5G era
The rapid proliferation of wireless communication devices and the emergence of a variety of new applications have triggered investigations into next-generation mobile broadband systems, i.e. 5G. Legacy 2G-4G systems covering large areas were envisioned to serve both indoor and outdoor environments. However, in the 5G era, 80 percent of all traffic is expected to be…
100 GHz reflectometer for sensitivity analysis of MEMS sensors comprising an intermediate frequency Six-port receiver
Due to the growing market for Micro Electro Mechanical Systems (MEMS), especially for the application in mobile electronic devices like cameras, phones or tablet computers, cost and time efficient test and evaluation systems are required for the production process. This work presents a novel measurement setup for MEMS microphones, that allows an inline, contactless evaluation of…
Inductive coupling effects in large TSV arrays
The effects of inductive coupling among TSVs within large TSV arrays are investigated in this paper. A comparison of the equivalent inductance of a paired TSV model and arrayed TSV macromodel is presented for three TSV distribution topologies, grouped, lined, and uniform, within the power network. Modified closed-form expressions are proposed to determine the equivalent inductance…
A Location-wise Predetermined Deployment for Optimizing Lifetime in Visual Sensor Networks
Visual sensor networks are receiving significant attention due to their potential applications ranging from surveillance to tracking domains. Nevertheless, due to the funneling effect, the unbalanced energy usage among visual sensor nodes (SNs) increases and leads to premature decrease in networklifetime. Firstly, considering Rayleigh fading channel and routing models, we analyze the optimization ofnetwork lifetime…
