A method for creating web programs and corresponding table interfaces according to column comments is revealed. The method features on that codes predefined are stored in the comment of each column in a table respectively and each code corresponds to a function. Then attribute data and the code of each column are obtained by metadata of a relational database. A program required for retrieving and storing data in the relational database is produced according to the attribute data and to the code. Thus a corresponding web code file is created. Finally, a table interface and a program for processing web pages of each column corresponding to the function are created by a web editing system according to the web code file. Thereby web application development is dramatically accelerated.

Due to the deregulation of power industry, the transmission expansion plan is different from the process done by the integrated monopolies. In a monopoly electric market, the transmission expansion plan is carried out by the vertically integrated utility. The power company integrates its generations' exploiting plans and its transmission expansion plans to maintain the system reliability. While in a deregulated power industry, generation, transmission, and distribution companies belong to different owners. The problem becomes more difficult. Generators experiencing transmission constraints can be expected to lobby for new transmission facilities that might relieve their constraints, while generators closer the load centers will likely toward not to build any new transmission facilities that would increase their competition. In order to provide a fair environment for all market participants, this paper proposed a reasonable expansion plan taking the operation cost, load curtailment cost, and investment cost into account. Due to the complexity of this model, the algorithm that combines the genetic algorithm with the linear programming method (GA-LP) is used to solve this problem. The 6-bus system and 24-bus IEEE reliability test system are used to verify the proposed model, and comparisons of test results between the proposed model and the traditional model are also demonstrated in this paper. © 2010 Elsevier Ltd.

Owing to the continuously increased electricity demands and power transactions, power systems are becoming more vulnerable to insecurity, generally incurred by overutilised transmission facilities or any contingency. In order for existing transmission networks to accommodate more power transfers with less network expansion cost, proper installation of thyristor controlled series compensator (TCSC) is validated to be one of the most 'promising options'. The multi-objective optimal TCSC installation strategy proposed in the study first applies the performance index sensitivity factor technique to investigate which lines are most necessary for TCSC installation and with the lines specified for TCSC installation and the multiobjective function consisting of maximum system loadability and minimum TCSC installation cost, the problem to determine the capacity for each TCSC installation is then formulated as a multi-objective optimisation problem and solved by using the fitness sharing multi-objective particle swarm optimisation method. Finally, in the Pareto front set obtained, the solution with the TCSC installations that can make the power system provide the required loadability with biggest utilisation index value is recommended. The modified IEEE-14 buses, IEEE-118 buses systems and a practical power system are used to validate the performance of the proposed method. © The Institution of Engineering and Technology 2014.

Owing to the constantly increased electricity demands and transactions, power systems are becoming more vulnerable to voltage instability generally incurred by over-utilized transmission facilities or any contingency. In order for transmission networks to accommodate more power transfers with less expansion cost, proper installation of Flexible AC Transaction Systems (FACTS) is a promising way. The power system loading margin enhancement problem to determine an optimal Static Synchronous Compensator (STATCOM) installation scheme can be formulated as a mixed discrete-continuous nonlinear optimization problem (MDCP). In the paper, to improve the efficiency of solving the MDCP, an ordinal optimization (OO) STATCOM installation strategy is proposed to seek a good enough solution rather than the optimal solution. In the strategy, under each N - 1 contingency with bigger risk index (RI) value, first the crude model of the MDCP is used to estimate the rough solution of each candidate in the representative set, and then the exact method is applied to a smaller set selected from the candidates with better rough solutions to determine the good enough solutions. Finally, obtained from the union of the respective good enough solutions for all considered contingencies, the scheme with the smallest number of STATCOM units or least capacity for installation enabling the network to provide required LM is recommended. The efficiency of the proposed method is confirmed with the results studied on IEEE-24 bus reliability test system. © 2013 Elsevier Ltd. All rights reserved.

Experimental evidence for the giant piezoresistance (PZR) effect in n-type silicon nanowires (SiNWs) on silicon-on-insulator wafers, also called SiNW field-effect transistors (SiNWFETs), is demonstrated. While an external mechanical strain is applied to SiNWFETs depleted by a back-gate bias, a marked increase in the subthreshold drain current is found, thus supporting the widely reported giant piezoresistance effect. This increase can be attributed to the change in Si/SiO 2 interface states, further suggesting interface trap-induced giant piezoresistance. Furthermore, through repeated cycles of tensile and released strain, the electromechanical response of the subthreshold drain current with time offers a potential for creating strain-gated SiNWFETs. © 2012 American Institute of Physics.

Experimental evidence is presented for silicon bandgap narrowing in uniaxially strained MOSFETs subjected to both tensile and compressive stress. For both n-channel MOSFETs with n + polysilicon gate and p-channel MOSFETs with p + polysilicon gate, the strain-induced threshold voltage shift (ΔV th) can be explicitly approximated from the changes in silicon bandgap (Δ E g) and carrier mobility (Δμ). From the measurements of both Δ V th and Δmu; associated with the strain a simple Δ E g model at low strain is found to exactly match a tight-binding band structure calculation, clearly indicating the presence of uniaxial strain-induced silicon bandgap narrowing, regardless of strain or carrier type. © 2012 IEEE.

Recent developments and advances in energy storage technologies are making the application of energy storage technologies a viable solution to power applications. The energy storage system can store energy previously, and then release it in the proper time. Due to their flexibility, it is suitable to apply this technology to deregulated power markets. Therefore, this paper will build the economic analysis model for the energy storage system to apply to a distribution substation in a deregulated power market. The costs including installing energy storage system and operation and maintenance expense, and the revenues containing energy price arbitrage, reducing transmission access cost, and deferring facility investment are considered in this model. All these factors are evaluated by present worth value. Due to complexity of this problem, this paper proposes a method combining the genetic algorithm with linear program (GALP) to determine the optimal capacity and operations of the energy storage system. © 2011 Elsevier Ltd.

Proper installation of flexible ac transmission systems (FACTS) in existing transmission networks can improve transmission system loading margin (LM) to a certain degree and reduce network expansion cost. In the paper, under each contingency with high risk index (RI) value, the modal analysis (MA) technique is used to determine which buses need static var compensator (SVC) installation, and with maximum LM and minimum SVC installation cost composed into the multi-objective function the optimal LM enhancement problem is formulated as a multi-objective optimization problem (MOP) and solved by using the fitness sharing multi-objective particle swarm optimization (MOPSO) algorithm for a Pareto front set. In the Pareto front set for each considered contingency, the solution with the biggest performance index value is determined for SVC installation. Finally, an SVC installation scheme derived from the union of the SVC installations for all considered contingencies is recommended for LM enhancement. The proposed method is validated on the IEEE 24-bus reliability test system (RTS) and a practical power system. © 2012 IEEE.

Tunable piezoresistive sensors based on a drawing on paper with different grades of pencils are proposed. While an external mechanical strain is applied to U-shape resistors prepared by pencil drawings on paper, an increase in the gauge factor with an increase in the graphite resistance is found. The result is attributed to the tunneling effect between neighboring graphite during the drawing process, further suggesting that different-grade pencil drawings can tune the piezoresistive properties. Through many cycles of repeatedly applied and released force, the output voltage for an HB pencil was found to be more sensitive than that for a 9B pencil. © 2014 AIP Publishing LLC.
