Abstract—This paper analyzes the 20 percent Sn4+-doped titania films who were prepared on the quartz glass humidity sensor by complex impedance analysis, improves the equivalent circuit model whose circuit description code is R(C(R(RC))). This equivalent circuit uses the constant phase angle element Q instead of the capacitance C in the second resistance-capacitance parallel entries, and its circuit description code is R(C(R (RQ))). The results show that the model is more reasonable, because the error is smaller when it is used to fit the impedance spectra of the sensor. The equivalent circuit is convenient for analyzing the diffusion information of the thin films because of the changes of the value of n.

Abstract - Weighted criteria is one of the important precedures in decision making. Each of the criteria has their own weights in predetermine the selection. It is normal practice in decision making to weight the criteria based solely on positive evaluation to represent degree of importance. However weights of criteria is possible to determine by considering two-sides evaluation. This paper proposes a method to estimate criteria weights under conflicting bifuzzy preference relations. The new preference offers an oppurtunity for decision maker to give judgment for both positive and negative evaluations simultaneously. The preference relations matrix is solved using the conflicting bifuzzy arithmetic averaging operator and score function. The aggregation is utilized by normalization prior weights determination. A numerical example is given to illustrate the proposed method. The ranking of the criteria is represented by the weights. It seems that an application of a score function in conflicting preference is a feasible tool in weights determination.

Abstract—In this paper, we propose a linear consensus protocol for networked multiagents. Different from the other protocols proposed before, it uses a state space form which can take the dynamics of the agents into account in a natural way. To deal with switching communication topology, the whole group dynamics is regarded as a time-varying system. Directed networks and undirected networks are both covered by this protocol with only a mild requirement that the whole multiagents group is connectivity. For the convenient we give out a general design routine of the decentralized controller of each vehicle to achieve the consensus. Simulations are carried out at the end to demonstrate the effectiveness of this protocol.

Abstract—This paper investigates the coordination of a decentralized supply chain in which a single manufacturer is selling a perishable product to a single retailer facing uncertain demand affected by her adverting expenditure and having shortage penalty. When the retailer behaving as a newsvendor faces stochastic advertisement-sensitive demands, she has to make the advertising and inventory decisions before the demand is realized. First, we establish that the supply chain can not be coordinated with the buy back, revenue sharing, and target rebate and quantity flexibility contract. Next, we show quantity discount contract can coordinate the supply chain and give a special quantity discount contract. Finally, we present a contract called revenue and loss sharing contract which mitigates the effect of shortage penalty loss and coordinates the decentralized supply chain.

Abstract—In this paper we present DSMAC-an energy efficient medium access control (MAC) protocol in wireless sensor networks which are widely used for long-time monitoring. Our protocol is designed for event-driven and ultra-low power sensor networks. Using dynamic sleep scheme to save energy is one of the key problems in this kind of system. The basic idea is that, when an event is apperceived by sensors, all nodes in the network use a value of grads to earmark the location of an event, which is used for data searching expediently, and all nodes adjust their sleep periods dynamically due to their grads. Simulations show that, our MAC protocol for event-driven wireless sensor networks shows higher efficiency than exists approaches and is more suitable for long-time monitoring.

The system can select appropriate phase sets for all modulated subcarriers for each PC code for different design requirements such as peak-to-average power ratio (PAPR) reduction or BER performance improvement. The proposed system will achieve better PAPR characteristics and promising BER performance. In addition, due to the flexible OFDM structure, the proposed PC-OFDM system will also have properties of high adaptability and compatibility.

Abstract— This paper proposes a new operation method for portable devices and controllers using fingertip pressure. The proposed system provides multivalued, biaxial outputs according to the fingertip pressure from two directions. Strain sensors are used to detect microscopic strains caused by the fingertip pressure on the body of the portable device. For verification experiments, a prototype consisting of a detection circuit with two strain gauges and a 32 bit MPU with an aluminum body was manufactured, and various applications were implemented. The experimental results indicate that the prototype system can output accurate linear data proportional to fingertip pressure from two directions. With the proposed interface, the portable devices do not require a specific area, thickness, or position for input buttons on their bodies.
Keywords- Fingertip pressure, strain gauges, biaxial input and output.

Abstract—This paper presents a design of residue amplification circuit (MDAC) used in the first 1.5-bit pipeline stage of an ADC, and the MDAC should meet requirements of a 100MS/s 14-bit pipeline ADC with 1.8V supply voltage. In order to obtain the corresponding performance, the circuits such as operational amplifier and bootstrap circuit are designed which could realize the objective of high-speed and high-resolution. The gain-boost structure is used in the amplifier to obtain the specified resolution, and an optimization between speed and power dissipation should be carefully conducted as a high speed requires a large slew rate or trans-conductance which is proportional to power dissipation. The design is implemented in the 0.18µm CMOS process with 9.6mW power consumption and the simulation results in Spectre illustrate that, the designed operational amplifier could reach the fixed objective and the residue signal of MDAC could set up completely in the specified time 3ns.
