Learning based hashing has become increasingly popular because of its high efficiency in handling the large scale image retrieval. Preserving the pairwise similarities of data points in the Hamming space is critical in state-of-the-art hashing techniques. However, most previous methods ignore to capture the local geometric structure residing on original data, which is essential for similarity search...
The core of existing cross-modal retrieval approaches is to close the gap between different modalities either by finding a maximally correlated subspace or by jointly learning a set of dictionaries. However, the statistical characteristics of the transformed features were never considered. Inspired by recent advances in adversarial learning and domain adaptation, we propose a novel Unsupervised Cross-modal...
This paper proposes a novel soft robotic design that possesses variable stiffness and position feedback. A gripper adopting this design is presented. Each finger in the gripper is based on a 3D printed substrate (driven by an air actuated soft actuator) composed of two smart materials: shape memory polymer (SMP) and conductive thermoplastic polyurethane (TPU). SMP's dramatic change of elastic modulus...
A 320 GHz on-chip 2 × 2 antenna array employing a compact feeding network is presented in this paper. The feeding network is designed based on the conducted-back coplanar waveguide (CBCPW) transmission line with a compact size, which has the full shielding performance providing good isolation from circuits around or below the CBCPW transmission lines. The proposed on-chip feeding network and antenna...
In this paper, we consider the energy efficiency maximization problem in downlink multi-input multi-output (MIMO) multi-cell systems, where all users suffer from inter-cell interference. To solve this optimization problem with a nonconcave objective function and a complex-valued matrix variable, we extend the recently developed successive pseudo-convex approximation framework and propose a novel iterative...
In this paper, we present a novel class of wearable antennas that are flexible, electronically tunable, and robust. They consist of conductive fabric parts, used as the radiator, with polydimethylsiloxane (PDMS) polymer utilized to form the substrate as well as the full encapsulation of the radiator including its electronic tuning elements. To validate the concept, a prototype that provides frequency...
The wireless sensors deployed at the highway can ensure the safety of the traveling vehicles. However, the ribbon deployed wireless sensor network in the roadside infrastructure can easily to generate energy hole. Cooperative communication between sensors and vehicles is an effective way to improve this situation and reduce the energy consumption of the sensors. A cooperative relay selection algorithm...
Abstract-With the rapid development of streaming media, communications between Device-to-Device is becoming a magnetic solution to improve the performance of cellular network.Although numerous papers have been published in the past, most of them just focus on novel description but ignore the classical theory to be innovated. In this paper, inspired by BitTorrent protocol, we propose a dynamic d2d...
Capacity-coverage tradeoff balancing is a classical but critical problem for practical wireless multi- cell network optimization. Increasing the average capacity is often at the expense of decreasing the cell coverage and vice versa. It becomes more complex in massive multiple-input/multiple-output (MIMO) networks to balance the above two performance indicators since capacity is much highly improved...
Millimeter wave (mmWave) communication has been a key technology for the fifth generation (5G) wireless communications. There have been various mmWave channel measurements. However, many measurements in the literature are conducted with different configurations, which may have large impacts on the propagation channel characteristics, and make the comparison of propagation channel characteristics for...
Although high oil prices have attributed bad habits in a matter of “doing things right” rather than “doing the right things” in subsea productions, a continuous price drop renewed the need for cost cutting in recent years. This has been the case for subsea companies, where previous research found significant cost and schedule overruns due to late design changes. A large amount of these late design...
LITMUS is a real-time online and openly accessible service that collects high quality information on landslide events from social media. This service uses disaster related keywords, such as "landslide" and "mudslide", to analyze messages posted by English speaking users. However, comprehensive coverage of disasters must include multilingual support as there are events that are...
With the development of cloud storage, data owners no longer physically possess their data and thus how to ensure the integrity of their outsourced data becomes a challenging task. Several protocols have been proposed to audit cloud storage, all of which rely mainly on data block tags to check data integrity. However, their block tag constructions employ cryptographic operations, which makes them...
Investigating the individual biomechanical relationship between jaw movements and masticatory muscle activities is an important research problem in dental research. In this work, we propose an approach to estimate the masticatory muscle tensions by the quantified muscle 3D morphologic changes during the maximum jaw opening. One healthy adult subject underwent magnetic resonance (MR) scans of the head...
This paper reports a minimized bio-particles manipulation tool utilizing localized ultrahigh frequency acoustic resonators (UHF-AR). The resonator works at frequency of 1540 MHz, which is high enough to break through scale effect and trigger localized acoustofluidic streaming (in formation of 3-D vortices) within microfluidic systems. Especially, the vortices can be precisely tuned in principle, providing...
This study aims to determine the construct validity of the Multi-dimensional Transformational Training Programs Scale in private universities in the Jordanian capital, Amman. The study involves a quantitative investigative approach via a questionnaire-based survey of all employees in private Jordanian universities in Amman. A total of 212 valid questionnaire was finally obtained. Exploratory and confirmatory...
Anomalies of multitier services running in cloud platform can be caused by components of the same tenant or performance interference from other tenants. If the performance of a multitier service degrades, we need to find out the root causes precisely to recover the service as soon as possible. In this paper, we argue that cloud providers are in a better position than tenants to solve this problem,...
In this paper, we study the power allocation and power splitting problem for simultaneous wireless information and power transfer (SWIPT) in a multi-user MISO broadcast system, in which there are two types of single-antenna users: traditional users that only receive information and modern users that receive information and energy simultaneously from a multi-antenna base station via power splitting...
As more than 2.5 quintillion bytes of data are generated every day, the era of big data is undoubtedly upon us. Running analysis on extensive datasets is a challenge. Fortunately, a significant percentage of the data accrued can be omitted while maintaining a certain quality of statistical inference in many cases. Censoring provides us a natural option for data reduction. However, the data chosen...
Compared with the traditional power grid, Energy Internet is motivated by the concept of intelligent energy sharing and coordination, achieving higher penetration of renewable energy and economic saving. In this paper, we propose a new framework for the time-slotted Peer-to-Peer (P2P) energy sharing and coordination in Energy Internet, which aims to achieve flexible and efficient distributed energy...
