MIMO-OFDM technology is the key technology for the IEEE802.11ac broadband wireless LAN standards. The physical layer implementation schemes of the IEEE802.11ac uplink multi-user systems was investigated. The simulation results of the performance for uplink multi-user MIMO-OFDM systems are given.
A standing-wave optical trap integrated with confocal Raman spectroscopy enables stable trapping and characterization of individual single-walled carbon nanotubes, graphene flakes, biological particles, SERS-active metal nanoparticles and other nanoparticles based on their increased Raman fingerprints.
In order to improve the information elements in fashion design display ability, feature extraction and pattern information for modeling clothing texture, a clothing texture pattern texture segmentation method the dynamic characteristics and speed up robust feature matching based on sparse interference on clothing texture acquisition case scattered point segmentation and denoising, color the introduction...
Direct position determination (DPD) is a single-step method which directly localizes transmitters from sensor outputs without computing intermediate parameters. Compared with conventional two-step localization methods, DPD achieves higher accuracy especially under low signal to noise ratio (SNR) conditions. This paper proposes an improved subspace data fusion (SDF)-based DPD algorithm with a moving...
Anticipating human intention by observing one’s actions has many applications. For instance, picking up a cellphone, then a charger (actions) implies that one wants to charge the cellphone (intention) (Fig. 1). By anticipating the intention, an intelligent system can guide the user to the closest power outlet. We propose an on-wrist motion triggered sensing system for anticipating daily intentions,...
Compositional models represent visual patterns as hierarchies of meaningful and reusable parts. They are attractive to vision modeling due to their ability to decompose complex patterns into simpler ones and resolve the lowlevel ambiguities in high-level image interpretations. However, current compositional models separate structure and part discovery from parameter estimation, which generally leads...
Many existing person re-identification (PRID) methods typically attempt to train a faithful global metric offline to cover the enormous visual appearance variations, so as to directly use it online on various probes for identity match- ing. However, their need for a huge set of positive training pairs is very demanding in practice. In contrast to these methods, this paper advocates a different paradigm:...
Focused ultrasound with nanodroplets could facilitate localized drug delivery after vaporization with potentially improved in vivo stability, drug payload, and minimal interference outside of the focal zone compared with microbubbles. While the feasibility of blood-brain barrier (BBB) opening using nanodroplets has been previously reported, characterization of the associated delivery has not been...
Acoustically-activated nanodroplets facilitate localized drug delivery after vaporization with improved in vivo stability, drug payload, and minimal interference outside of the ultrasound focal zone compared with microbubbles. They are new acoustic mediators to induce blood-brain barrier (BBB) opening for drug delivery to the brain, with promising potential of extravasation to enhance targeted delivery...
People are increasingly dependent on intelligent electronic products. However, the vast majority of these intelligent electronic devices are highly dependent on external power supply. If there is no continuous power supply to the equipment for some unknown reasons, the equipment will not be able to work properly, or even will bring us some serious unpredictable consequences, which poses a new challenge...
Music emotions recognition (MER) is a challenging field of studies addressed in multiple disciplines such as musicology, cognitive science, physiology, psychology, arts and affective computing. In this paper, music emotions are classified into four types known as those of pleasing, angry, sad and relaxing. MER is formulated as a classification problem in cognitive computing where 548 dimensions of...
This electronic document is a "live" template and already defines the components of your paper [title, text, heads, etc.] in its style sheet. The Internet has revolutionized the way we communicate. In particular, Instant Messaging (IM) as a social media platform can meet the demands of omnipresent communication, and hence constantly using IM has become routine activities of most people....
Dempster-Shafer(D-S) method has been used widely in fault diagnosis system of civil aircraft electrical system, but it has difficulty in dealing with combining evidences with high degree of conflict. In order to solve the problem, a new method is proposed in this paper. The proposed method in this paper introduces the historical data, defines the concept of modifying factor, and considers the influence...
This paper proposes a vehicle blind spot detection (BSD) system to reduce the traffic accident when car was changing lanes on the road. The cameras are installed at the bottom of the left and right side view mirrors. The system reaches 99% vehicle detection rate and is applicable during daytime and nighttime without high-cost radar. Furthermore, the system integrates with functions of auto cycle video...
The introduction of verifiable computation came as a result of the increasingly common phenomenon of "outsourcing" computation to untrusted servers and also to the growing desire of weak clients to outsource computational tasks to more powerful computation services like in cloud computing. Verifiable computation enables a computer to offload the computation of some function, to other perhaps...
The world's first GeSn p-FinFETs formed on a novel GeSn-on-insulator (GeSnOI) substrate is reported, with channel lengths Lch down to 50 nm and fin width WFin down to 20 nm. In comparison with other reported GeSn p-FETs, record low S of 79 mV/decade, record high Gm, int, of 807 μS/um (VDs of −0.5 V), and the highest Gm, int/Ssat, were achieved. The highest high-field hole mobility of 208 cm2/Vs (at...
Record-low specific contact resistivity ρc down to 1.2×10−9 Ω-cm2 is achieved for Ti/p+-Ge0.95Sn0.05 contact by incorporating Sn into Ge and insitu Ga doping with active doping concentration of 1.6×1020 cm−3. As compared with Ni(GeSn)/p+-Ge0.95Sn0.05 contact, Ti/p+-Ge0.95Sn0.05 contact exhibits lower ρc and is more thermally stable. In addition, theoretical calculation shows that for a given doping...
In order to solve the problem of traffic accidents that caused by drivers and passengers open the door abruptly, this paper proposes a door open alarm (DOA) system that uses the camera as the sensor, and applies two analog cameras that set at the both side view mirrors to get the video information. This paper is based on image processing to develop the algorithm and has been implemented on Renesas...
Cybercrimes are emerging trends on the Internet. Free instant communications, like LINE or WhatsApp, bring close to our family and friends around the globe. People in Taiwan use LINE application more frequently than others. This study uses Wireshark to explore the cybercriminal behind the LINE voice calls. Some algorithms are identified to the criminal's IP address by way of LINE voice calls. It will...
Biosignals-based affective computing plays an important role in human-computing interaction. In recent years, a lot of works have been successfully implemented for emotion recognition with biological signals. However most of them are computationally expensive due to the complexity of models. In this paper, we present a multi-label learning (MLL) method to map biological signals to an affective model...
