The uniform boundedness with respect to part of the retarded functional differential system variables is studied. The obtained result in this work utilize Lyapunov functions to determine the uniform boundedness of solutions of the Nonlinear retarded system. The result for the partial boundedness develop some theorems on uniform boundedness of ordinary differential system. An example is presented which...
Regret is a negative social affect arising from upward counterfactual thinking for adverse outcomes. The neurophysiologic markers of identifying regret based on feature extraction from EEG signal has yet to be investigated. The EEG signals were recorded while 25 subjects performed a gambling task involving feedback for the subjects' chosen selection, the alternative selection, or for both. After the...
Group Purchase is discussed for a distribution channel including one manufacturer and three retailers. Retailers' optimal order quantities and optimal profits are analyzed under two kinds of strategies, namely the separate purchase and group purchase. Then the optimal ordering strategy is discussed for the single retailer under the various modes of cooperation. The results are shown that the dominant...
This paper presents an analytic model for double gate (DG) tunnel FETs with 3D density of states. By evaluating two WKB integrals for mixed electron and hole tunneling, continuous current-voltage characteristics are generated with a single integral over the carrier energy. The model covers both heterojunction and homojunction TFETs. The results have been verified by numerical simulations. An expression...
With characteristics analysis of the vibration signal from the diesel engine, a new method for identifying the characteristic frequency band is put forward by adopting its IMF component. The diesel engine vibration signals are disposed by using EMD method and the IMF components with respond to the main interference factors is eliminated. Then, the true vibration signal from diesel engine could be...
An operation in 1.8V supply voltage single-ended cascode low-noise amplifier (LNA) structure was launched. This designed circuit provided the lower noise figure and matched the suitable LC tank to enhance the central operating frequency as well as the excellent input and output impedance matching incorporated into this LNA circuit. In this simulation, the Agilent ADS (Advanced Design System) simulation...
Mismatched lattice constants between SiGe and silicon can cause the strain making the mobility improved. SiGe are grown underneath the channel apparently to form global strain over the whole devices, while Source/Drain refilled with SiGe would squeeze or pull up the devices uni-axially. The ID-VG characteristics curves and the maximum trans-conductance (gm) using strain engineering are observed to...
Strained Engineering including both global and local strains effectively enhances the mobility of carriers, in which global strains are generated by the mismatching of lattice constants at the junction of Si and Si0.775Ge0.225 and local strains are aroused by Source/Drain refilled with SiGe. In this paper, junction breakdown voltage, punch-through voltage, and the variation of threshold voltages are...
Based on the requirement of the transmission of real-time service in wireless sensor networks, the paper studies Weighted Fair Queuing (WFQ) algorithm profoundly. Having analyzed the reason why WFQ can't ensure the quality of real-time service, it proposes P-WFQ, which is a priority-based Weighted Fair Queuing (P-WFQ) algorithm. With sliding windows, P-WFQ combines WFQ and the priority-based mechanism...
For the solution of the problem that compaction of loose defects inside ingot is more difficult than forging cavitary defects together, in this paper, numerical simulation with DEFORM software is performed for the compaction process of loose defects inside forging of low-pressure rotor of 600MW steam turbine, the Simulation results are basically consistent with experimental results, it shows that...
Wireless sensor networks are formed by a great deal of sensor nodes, which are generally battery-powered and may not be recharged easily. Consequently, how to save energy is an important issue when designing protocol in wireless sensor network. However, lowering the energy consumption may result in higher latency. To address such a tradeoff, this paper proposes a MAC protocol supported dynamic contention...

Related performance, namely, signaling...
Aiming at the refinement of rotor center's orbit, a novel method was proposed based on the adaptive structure element for generalized morphological filtering (ASEGMF). At first, the sine structure element was selected, and the length scale and the height scale were defined according to the feature of vibration signal. Then, the peak interval and the peak height were defined by signal's local characteristic,...
Wireless sensor network is formed by a great deal of sensor nodes, which are generally battery-powered and may not recharge easily. Consequently, how to prolong the lifetime of the nodes is an important issue when designing protocol in wireless sensor network. However, lowering the energy consumption may result in higher latency. To address on such tradeoff, this paper proposes ADC-SMAC to improve...
Power System Stabilizer (PSS) is widely applied in power systems as an effective measure to damping the low frequency oscillations. The control effectiveness of PSS is fundamentally determined by appropriate parameters. The conventional method for setting the parameters of PSS only takes a single oscillation mode into account, which may have sub optimal damping performance in other modes. As a further...
Cloud services are charming for vehicular ad hoc network (VANET) users. Advances of wireless networks make access to the Internet from VANETs possible. However, the features of VANETs hinder the delivery of cloud services to VANETs. It is important to find proper Internet gateways to connect the VANET users to the cloud. A cloud-assisted gateway discovery scheme is proposed in this paper. The simulation...
The main objective of MAC protocol design is introduced, and the typical S-MAC protocol in wireless sensor networks is analyzed.
