While extending network programmability to a larger degree, P4 also raises the risks of incurring runtime bugs after the deployment of P4 programs. These runtime bugs, if not handled promptly and properly, can ruin the functionality and performance of networks. Unfortunately, the absence of runtime debuggers makes troubleshooting of P4 program bugs challenging and intricate for operators. This paper...
HBT effect of thermal light between different modes based on multi-mode interference is directly observed in a modified Michelson interferometer with orthogonal polarizations by a two-photon absorption detector at ultrashort timescale, which serves as a new unique tool for ultrafast quantum bunching distribution.
Object detection aims at high speed and accuracy simultaneously. However, fast models are usually less accurate, while accurate models cannot satisfy our need for speed. A fast model can be 10 times faster but 50% less accurate than an accurate model. In this paper, we propose Adaptive Feeding (AF) to combine a fast (but less accurate) detector and an accurate (but slow) detector, by adaptively determining...
Edge and surface are two fundamental visual elements of an object. The majority of existing object proposal approaches utilize edge or edge-like cues to rank candidates, while we consider that the surface cue containing the 3D characteristic of objects should be captured effectively for proposals, which has been rarely discussed before. In this paper, an object-level proposal model is presented, which...
Recently developed press-pack IGBT (PPI) modules, which feature higher voltage rating, larger thermal capacity, faster switching speed and easy utilization in series, have become a serious competitor with solder plastic IGBT modules in the field of voltage-source-converter based high-voltage-direct-current (VSC-HVDC) transmission systems. To give a comprehensive investigation of press-pack IGBT modules,...
As the feature size of semiconductor technology continues to scale down, conventional synchronous circuit design methods encounter more and more design challenges, one of which is the routing of global clock trees meeting timing and power requirements. Asynchronous circuits, which do not rely on global synchronization, provide alternative opportunities to their synchronous counterparts. This paper...
This paper studies the challenging activity recognition task and a novel discriminative action pattern is proposed. We construct action cube pool and propose a novel scheme to represent action cubes as action patterns. Candidates of discriminative patterns are selected among action patterns according to motion energy of corresponding action cube. Spatial constraint clustering algorithm clusters these...
In this paper, a novel comprehensive design, including inverter and motor topology, and PWM scheme, is proposed to reduce iron losses for high speed induction motors. In the proposed method, two inverters are connected with a twin-coil motor. Two counteracting PWM schemes are applied in the two inverters, feeding the same fundamental currents into the twin coils, meanwhile switching in opposite phase...
Aiming at providing united control of multi-domain optical networks orchestration, we design the Federated Platform based on Open Network Operating System (ONOS). Our implementation includes adding and extending modules in ONOS to provide the global view of multi-domain networks and support cross-domain end-to-end services by communicating with the individual domain controllers through RESTCONF protocol...
P4 is a domain specific language designed to define the behavior of a programmable data plane. It facilitates offloading hardware-suitable Network Functions (NFs) to a data plane. Consequently, NFs can maximally benefit from high performance of hardware devices, meanwhile more CPU power can be reserved for user applications. However, since the programmable data plane provides an NF with an exclusive...
A novel communication scheme called touchable communication (TouchCom) in the nanoscale and molecular communication area has been recently proposed. It is focused on the controllable and trackable properties of message carriers. A potential therapeutic application of TouchCom is the targeted delivery of drugs which utilizes physically transient nanobots as vehicles to deliver drug particles. Meanwhile,...
Microsecond and nanosecond lasers have been studied in the past for laser cleaning applications, but femtosecond laser is rarely used for cleaning due to the greater possibility of ablation from the extremely high peak power (in gigawatt range) of ultrashort pulses. This paper reports the investigation into the feasibility of using femtosecond laser as a tool for surface cleaning of aerospace components...
With the popularization of human-carried devices, it is possible for Mobile Crowd Sensing (MCS) applications to perform large scale sensing with sensors embedded in these devices. Many incentive mechanisms for MCS applications have been proposed due to the importance of attracting more worker to participate. However, these mechanisms failed to consider situations where there are constraints on both...
Meta-search engine is a comprehensive search tool, which is build base on those member search engines. All result entities reported by member search engines are merged into one ranked list according to their quality. It is well knowing that the core problem in meta-search engine is how to merge the results and provide user with a more effective rank list. This paper dealt with a synthesized merging...
The post-matching (PM) topology is an effective approach to broaden the bandwidth of Doherty power amplifiers (DPA). However, its efficiency has been limited because previous works only considered the fundamental frequency termination, and not the harmonics. In this paper, a modified phase compensation network is used in the PM Doherty topology to realize a third harmonic open as viewed by both carrier...
Due to its high matching precision, DTW is an important similarity measure for time series. However, the high computational complexity restricts its application on mass data sets. To solve the problem, a combined filtering search is proposed, which combines lower-bounding technique and early-abandon strategy, to reduce the redundant computation. The experimental results indicate that the proposed...
This paper presents a low-cost reusable Atomizing Liquid Micro-thruster (ALM) that can produce intermittent streams of water sprays based on thermal bubble-jet effect using batch-fabricated PCB micro-heaters. The propulsion performance of the micro-thruster has been studied in two methods: (a) by measuring its average weight loss during each spray and the velocity profile of the ejected droplets;...
Recently, functional network connectivity (FNC) is widely applied to detect the functional organization of brain network in the field of psychiatric illnesses analysis. Conventional FNC analyses assume that temporal stationarity and ignore the topology information among multiple brain regions. By the graph encoding of static FNC and dynamic FNC, in this paper we performed a graph approach combining...
Aiming at the loss of angle information and detection accuracy of traditional radar system, the paper puts forward the Network Radar Countermeasure System active, passive and integrated anti-stealth detection model. The model, which is based on single-bistatic equivalent principle and simplification model of RCS, combines the advantages of bistatic radar, netted radar, MIMO radar, passive radar, etc...
Application Programming Interface (API) documents represent one of the most important references for API users. However, it is frequently reported that the documentation is inconsistent with the source code and deviates from the API itself. Such inconsistencies in the documents inevitably confuse the API users hampering considerably their API comprehension and the quality of software built from such...
