  • This paper presents an optimal operation control method for energy saving in the water reuse pumping system. A predictive horizon switching strategy is proposed to implement an optimal operation control and a linear programming (LP) algorithm is used to solve optimal problems in each time step. Energy costs are calculated for electricity on both TOU in the light, heavy, and maximum load time period and peak charges. The optimal operation in water reuse pumping systems is determined to reduce the TOU and peak costs. The simulation results show a power energy saving for water reuse pumping systems and power stability improvement.

  • In order to improve software development productivity and quality, reuse approaches and supporting library systems have been proposed. Library systems have applied various methods to classify, store, retrieve, and comprehend reusable components effectively. As the number of library systems grows, it is difficult to categorize, compare and analyze existing reuse libraries. In this paper, we present classification criteria for reuse library systems. A set of criteria is defined by integrating facet-based and attribute-based classification methods which encode the properties of a reusable component. In order to show the usefulness of the proposed classification criteria, representative library systems based on application domains, as well as component classification methods ore selected and reviewed. We then classify these library systems according to the proposed criteria.

  • In this paper, we present a reducing power consumption of a scheduling for reuse module selection under the time constraint. Traditional high-level synthesis do not allow reuse of complex, realistic datapath component during the task of scheduling. On the other hand, the proposed scheduling of reducing power consumption is able to approach a productivity of the design the low power to reuse which given a library of user-defined datapath component and to share of resource sharing on the switching activity in a shared resource. Also, we are obtainable the optimal the scheduling result in experimental results of our approach various HLS benchmark environment using chaining and multi-cycling in the scheduling techniques.

  • Reuse-partitioning is a simple technique that can be used to improve the capacity of a cellular system. In the previous researches, authors do not explain how a channel is selected and what happens when there is no channel available when a call arrives. Therefore, in this paper, we describe a simple channel selection procedure and analyze the performance of a system. The performance is presented in terms of the channel utilization and call blocking probability by varying offered load per cell. Our analytical results may be added in a realistic performance analysis of reuse-partitioning-based system.

  • This paper is an empirical study especially to understand recent Chinese internet banking users' behavior and intentions through the process quality, outcome quality, customer satisfaction, reuse and word of mouth on internet banking service. The results of this study are as follows. First, percieved process quality of internet banking service affects the outcome quality, and both quality have a direct relation to customer satisfaction. It is found that Chinese internet users perceive a difference between process quality and outcome quality of internet banking service. And the reuse of the internet banking is decided by customer satisfaction as well as the word of mouth of the internet banking. For successful internet banking business in China, internet marketers should recognize that the service quality consists of the process quality and the outcome quality, and they should organize a new campaign that takes this information into consideration. And considering the process quality effect, they should pay attention to service process as well as the direct merit of services.. And if an internet banking service properly meets customer demands, internet users would constantly use internet services and would share good experiences with their neighbors. Therefore the result of our study will be of working-level help for financial company in China.

  • Software architectures can be restructured by modification and replacement during design processes, and appropriate software architectures for developments can be more than one. Therefore, developers are required to specify efficiently the modification elements of architectures, and manage different versions of an architecture designed for various aspects. In this paper, we propose a mechanism that can restructure legacy architecture and a new software architecture designed with reuse of it in integrated form, and define the specification elements and structure of the proposed architecture restructuring specification. It provides the method that can reference and reuse architectures designed with various aspects of developers in architecture design processes.

  • Rhodococcus sp. strain p52, a previously isolated dibenzofuran degrader, could effectively inhibit the growth of cyanobacteria, including species of Microcystis, Anabaena, and Nodularia. When strain p52 was inoculated at the concentration of $7.7{\times}10^7$ CFU/ml, 93.5% of exponentially growing Microcystis aeruginosa ($7.3{\times}10^6$ cells/ml initially) was inhibited after 4 day. The threshold concentration for its algicidal activity against M. aeruginosa was $7.7{\times}10^6$ CFU/ml. Strain p52 exerted algicidal effect by synthesizing extracellular substances, which were identified as trans-3-indoleacrylic acid, DL-pipecolic acid, and L-pyroglutamic acid. The effective concentrations of trans-3-indoleacrylic acid and DL-pipecolic acid against M. aeruginosa were tested to be 0.5 mg/l and 5 mg/l, respectively.

  • For the reuse of the existing 3D block model of a ship, we analyze the hull modeling process using AVEVA Marine which is a representative CAD (Computer-Aided Design) system for the shipbuilding. In the AVEVA Marine environment where the design engineer makes 3D model on the 2D view that is so-called 2.5D, it cannot be possible to copy to reuse the block model just simply copying the 3D feature model itself like in the general mechanical CAD system or Smart Marine 3D which are on the basis of the 3D model representation. In this paper, we analyze the scheme file where the 3D model is defined in AVEVA Marine so that we develop the program for the block copy and the translation using this scheme file. It is significant that this program can be immediately available as a real-world application on the AVEVA Marine environment.

  • Formwork accounts for 10% of the total construction cost and 30~40% of the framework cost, which is a fairly large part. Various system forms were developed for improved economic feasibility and constructability of formwork and for reduced construction duration. In general, the price of system forms per unit area is higher than that of the conventional method, yet the total construction cost can be reduced through higher reusability and constructability. However, if the reusability of forms is excessively increased to cut down the material cost, it may increase the construction duration, which will result in cost increase. On the other hand, if the reusability is decreased for reduction of construction duration, it may lead to cost increase caused by excessive input of materials. To solve such a problem, an algorithm for simplified reuse planning that meets the requirements of construction duration, cost, quality and safety is required. In this regard, the study intends to perform a fundamental research for development of reuse planning automation algorithms on system forms that are used on girders and beams.

  • This paper proposes a 401MHz-406MHz low noise amplifier for MedRadio applications. The proposed low noise amplifier adopts a common gate amplifier topology using current reuse gm-boosting technique. The proposed low noise amplifier shows better performance of voltage gain and noise figure than the conventional gm-boosted common gate amplifier in the same power consumption. The proposed current-reuse gm-boosted low noise amplifier achieves a voltage gain of 22 dB, a noise figure of 2.95 dB, and IIP3 of -17 dBm while consuming $170{\mu}W$ from a 0.5 V supply voltage in $0.13{\mu}m$ CMOS process.
