Understanding usage and activity in cellular networks by investigating HTTP requests

The number of mobile devices is estimated to now exceed the world’s population, using more and more cloud services, and hence generating more and more traffic. Smartphones generate 95% of the total global handset traffic, and while approximately half of…

A New Frontier in Ultralow Power Wireless Links: Network-on-Chip and Chip-to-Chip Interconnects

This paper explores the general framework and prospects for on-chip and off-chip wireless interconnects implemented for high-performance computing (HPC) systems in the context of micro power wireless design. HPC interconnects demand very high (≥ 10 Gb/s) transmission rates using ultraefficient…

Algorithms and Applications for Community Detection in Weighted Networks

Community detection is an important issue due to its wide use in designing network protocols such as data forwarding in Delay Tolerant Networks (DTN) and worm containment in Online Social Networks(OSN). However, most of the existing community detection algorithms focus on binary networks. Since most networks are naturally…

VNCCrack: A Tool for Auditing Corporate Environments for the Presence of Insecure VNC Installs

VNC has long been used a means of providing remote connectivity between computer systems, but is all too often deployed in an insecure configuration. This paper describes an auditing tool that can be used to identify the presence of insecure UltraVNC installs…

Active learning for the prediction of prosodic phrase boundaries in Chinese speech synthesis systems using conditional random fields

Prosodic structure contributes to speech production and comprehension. One of the crucial problems in achieving natural-sounding synthesized speech is the prediction of appropriate phrase boundaries. Unfortunately, obtaining human annotations of prosodic phrases to train a supervised system can be laborious…

Dual Use of Power Lines for Design-for-Testability–A CMOS Receiver Design

As the circuit complexity increases, the number of internal nodes increases proportionally, and individual internal nodes are less accessible due to the limited number of available I/O pins. To address the problem, we proposed power line communications (PLCs) at the…

Experimental demonstration of Virtual Network Controller for abstraction and control of multi-tenant multi-technology transport networks

A network hypervisor is demonstrated. The Virtual Network Controller dynamically deploys multi-tenant virtual networks on top of multi-technology transport networks. It provides an abstract view of each virtual network and enables its control through an independent SDN controller.

Regularizing DNN acoustic models with Gaussian stochastic neurons

Dropout and DropConnect can be viewed as regularization methods for deep neural network (DNN) training. In DNN acoustic modeling, the huge number of speech samples makes it expensive to sample the neuron mask (Dropout) or the weight mask (DropConnect) repetitively from a…

Spectral and energy efficiency of ultra-dense networks under different deployment strategies

To tackle the 1000× mobile data challenge, the research towards the 5th generation of mobile cellularnetworks is currently ongoing. One clear enabler toward substantially improved network area capacities is the increasing level of network densification at different layers of the overall heterogeneous radio access system.…
