The objective of this study is to identify the key technology with analysis of the cost boundary of future photovoltaics (PV) technologies using life-cycle costing. We estimate the amount cost of photovoltaic system in Japan. It considers material flows over the whole production process starting from silica extraction to the final panel assembling. The comparison of current scenario to the expected future PV technologies focusing on the equipments in each production processes results in factory scale boundaries. ©2010 IEEE.

Active learning during out-of-school time Energy Clubs, can positively affect students in grades 3-5 by improving their understanding of technology, what engineers do, the engineering design process, and how to improve a windmill. RAMP-UP assessed the impact through a pre- and posttest from the engineering is Elementary workbook, "Catching the Wind."[2] After completing one activity where the students built windmills out of milk cartons, there were positive improvements in their understanding of technology, what engineers do and the engineering design process ranging from 3% to 8%.

Neither traditional, agile or free/open software development models can be effective to all projects contexts. We claim that collaboration and discipline can be the driver to tailor software development processes to meet projects and organizations needs. This work proposes that process tailoring can be conducted through a context management approach.

The identification of nonlinear systems with artificial neural networks models has been successfully used in many applications. Most processes in industry are characterized by nonlinear and time-varying behavior. In this context, the identification of mathematical models for nonlinear systems is vital in many fields of engineering. The Radial Basis Function Neural Network (RBF-NN) is a powerful approach for nonlinear identification and can be improved using Particle Swarm Optimization (PSO) approaches. This paper presents a multivariable nonlinear system identification using RBF-NN combined with standard PSO and Constriction Factor PSO (CFPSO) approaches in order to determine the RBF-NN parameters. RBF-NN is considered to be a good choice for black-box modeling problems due to its rapid learning capacity and, therefore, has been applied successfully to nonlinear time series modeling and nonlinear identification. On the other hand, PSO was inspired by the choreography of bird flocks and fish schools and can be seen as a distributed behavior algorithm that performs multidimensional search. Furthermore, promising simulation results from performance analysis of the proposed RBF-NN with PSO training approaches are presented and discussed in this paper showing promising results.

In this paper, a novel microelectrical impedance spectroscopy (μEIS) with three-dimensional interdigitated electrodes (3D-IDE) is developed to differentiate normal and cancerous cells. The device utilizes a microfluidic tunnel structure, which forces cells to be squeezed. Thus, the enlarged contact area between cells and electrodes allows the device to measure the intrinsic electrical signal of the cells with a higher sensitivity than a noncontact case. The cell squeezing is realized by fabricating smaller microfluidic channel than cell size. The electrical impedances are measured through 3D-IDE. The device well distinguishes normal human breast cell (MCF-10A) and early-stage human breast cancer cell (MCF-7) with a phase difference of 1.42° at 500 kHz. The proposed device also features a high repeatability because the phase change is as small as 0.27° (which is sufficiently smaller than the phase difference between normal and cancer cell) before and after the each cell assay.

This paper presents a mechanical cell lysis microfluidic chip with an ultra-sharp nano-blade array fabricated by simple and cost effective crystalline wet etching of (110) silicon. The ultra-sharp nano-blade array is simply formed by the undercutting during the crystalline wet etching process. The sharpness of the silicon nano-blade is less than 10 nm after the undercutting. EL4 mouse T-lymphoma cells are used for the demonstration of the mechanical lysis chip, and the cells are easily disrupted by the silicon nano-blade array without helping of additional reagents or electrical sources. The time-resolved observation of the mechanical cell lysis shows that the developed silicon nano-blade array is enough to easily disrupt the cell membrane even at very low flow rate of 0.7 ¿¿/hr.

60 GHz band has advantages in terms of broadband, frequency reuse, dimension of circuit, size of layout, and power. A wide bandwidth available in 60 GHz band is ideal for the high data rate transmission. It is also advantage of 60 GHz band that the passive circuit can be made very small. Due to those advantages, this band now is applied to Millimeter-wave (MM-wave) video transmission, outdoor and indoor wireless system, wireless Gigabit Ethernet link, and 60 GHz wireless LAN application. A low temperature co-fired ceramic (LTCC) becomes a technology of choice when it comes to MM-wave band. However, LTCC shows several issues on integration of MM-wave circuits such as; attenuation, resonance and isolation of passive circuits. This paper described the design techniques for an efficient low loss LTCC passive transmission lines. LTCC passive transmission line was design in the 6-layers of LTCC dielectric substrate, using Advance system Design (ADS) and Computer Simulation technology (CST) for EM simulation. Analysis and measurement of transmission lines using different substrate height of 100 μm and 114 μm was also presented. The proposed structure is validated by full-wave simulation, and experimental measurements. The analyses of fabricated modules with 100 μm and 114 μm shows the passive transmission lines achieved the insertion loss less than -1dB and return loss less than -10dB.

This research presents a systemic method to the innovative design of M14 rifle trigger mechanism based on TRIZ. We used the system Functional Analysis to define the functions for the components of trigger mechanism, the Strategy Edition to evaluate the value of the components for selection and deletion of the lower value components to simplify the trigger mechanism. The technical parameters, the invention principle, and the contradictory matrix of TRIZ were applied to solve the contradictory problem generated during the innovative design process. Finally, we created the 3D modeling of parts and simulation of the new trigger mechanism to prove its feasibility. After we applied this systematic method to the M14 rifle trigger mechanism, not only fewer components has made, but the trigger mechanism newly designed can do all the functions of original design;it can be also replace the original trigger mechanism to install into M14 rifles.
