In order to meet the demand of designing the waste gas efflux self-sucking device simply and practicably, based on the single-phase isentropic gas flow theory, a more effective theory analysis and design method was presented. The device’s main working parameters and characteristic indexes that had a signification effect in practice application were analyzed and given. And their calculating means were put forward. Some model was designed by this way and the parameters were analyzed by comparison with experiments. The result of the calculating case shows that the calculated data accord with the experimental data. And the method has good reliability with simpleness and practicality, which provides a good way of designing the self-sucking device.

Flow, the concept developed by Mihaly Csikszentmihalyi over the last forty years or so (see Csikszentmihalyi 1975) has been invoked quite often with respect to the way players engage with digital games (e.g. Baron 2012; Cowley et al. 2008; Sweetser and Wyeth 2005; Brathwaite & Schreiber, 2009; Fullerton, Swain, & Hoffman, 2008; Schell, 2008). However, Kubey & Csikszentmihalyi (2002) have argued that ‘video games’ are in fact likely to promote undesirable experiences of a kind Csikszentmihalyi refers to as ‘entropy’ or unstructured and unsatisfying life experiences. This paper explores Csikszentmihalyi’s greater thesis and examines how a broader reading of Flow theory can potentially help us understand Flow like engagements beyond the simple mechanistic view of challenge explicitly introduce personally expressed cultural values into the conditions of Flow. By doing so we can then provide a value centric analysis and design approach, similar to that of Cockton’s (2004; 2012) proposal, to include values in general software design. That is, the very nature of challenges and rewards needs to be considered in order to investigate how overcoming or receiving such challenges would be positively or negatively perceived by individuals, from particular cultures, holding particular values. Thus we hope that we have dealt with the apparent contradiction in using Csikszentmihalyi’s concept in the study of games despite his criticism of such a move, and have provided some indication of how we can deal with unspecified rewards and the differential perception and engagement with potentially equivalent challenges while still supporting the accepted thesis of Flow.

The problem in marketing department in this company do not have promotion media for offer the products to consumer, no online sell, and order only by phone. To solve the problem in marketing department is build up e-commerce system. E-commerce system use Unifed Modelling Languange (UML); Activity Diagram, Use Case Diagram, Sequence Diagram, and Class Diagram. User Centered Design (UCD) as design method. Program language for e-commerce system is PHP and MySQL for database. The result of research is a e-commerce system website base to help search information product, company could get report easier, consumer can do purchase by online everywhere and everytime.

The main problems of current system in agriculture ministry is sub-optimal information retrieval of realization and development of agriculture capital and production facilities subvention. Therefore, this research aims to analyze and design information system for monitoring and evaluation of subvention of agriculture capital and production facilities. This information system is developed based on internet technology to help the main team (agriculture minister and technical team of directorate agriculture department), coach team of provincial agriculture office, and technical team of district/city agriculture office to access the accurate information related realization and development of agriculture business any where and any time. It is designed with OOAD (object oriented analysis and design) method by using UML notation (use case diagram, class diagram, component architecture and user interface design). This research produces a design of information system for subvention monitoring and evaluation of agriculture capital and production facilities for the ministry of agriculture RI.

Rotatable Design

A central composite rotatable design (CCRD) methodology was used to analyze the effect of some operating variables on gas-liquid two phase mixing time in an agitated tank driven by dual 6-blade Rushton turbines. The variables chosen were the impellers rotational speed (x1), gas flow rate (x2), probe location (x3) and tracer injection point (x4). The mathematical relationship of mixing time on the four significant independent variables can be approximated by a nonlinear polynomial model. Predicted values were found to be in good agreement with the experimental values (R-sq of 95.9 percent and R-Sq (Adj) of 95.7 percent for response Y). This study has shown that central composite design could efficiently be applied for the modeling of mixing time, and it is an economical way of obtaining the maximum amount of information with the fewest number of experiments.

The influence of pressure on the gas/liquid interfacial area is investigated in the pressure range of 0.2–0.3 MPa by using a tray column test rig. A simulated waste gas, which consisted of 30% CO2 and 70% air, was used in this study. Distilled water was employed as an absorbent. The temperature of the inlet water was 19 °C. The inlet volumetric flow rate of water was 0.17 m3/h. Two series of experiments were performed; the first series was performed at inlet gas flow rate 15 Nm3/h, whereas the second series was at 20 Nm3/h of inlet gas flow rate. The results showed that the gas/liquid interfacial area decreases when the total pressure is increased. The effect of pressure on the gas/liquid interfacial area at high inlet volumetric gas flow rates is more significant than at low inlet volumetric gas flow rates. The authors studied the effect of decreasing the interfacial area on the performance of a tray column for CO2 capture.
