The purpose of this study is to propose an efficient design-VE job plan and applicable methods in each phase of design process. This is for more effective and practical use of VE in design phase. This study focuses on differences of the VE target selection phase and function analysis phase in each phase of design process. In the phase of preliminary design, conceptual sketch, size, use, or major spaces of project are selected for VE target and function assessment step is skipped because present cost and function cost cannot be produced easily in early in early phase of design. At the end of preliminary design phase, function review phase is added which consists of function satisfactory indices review step and unsatisfactory function removal step.

In this paper we evaluate the performance of the cached RAID5 which uses the parity cache and the data cache to overcome the small write problem. From the result of the simulation study we show that the cached RAID5 provides performance improvement with reasonable cache size.

Some authors suggest that certain types of surfaces are the origin of such injuries. A few years after the first medical concerns about surfaces were voiced, publications of biomechanical measurements apperared, describing accleration, force, and impact measurement on different types of surfaces. In many sport activities, surfaces can be under very high dynamic load. This was the reason for the development of various methods for impact simulation, like the development of various methods for impact simulation, like the artificial athlete. Furthermore, it is important to collect information about the hardness of new and already existing surfaces in sport arenas. The idea on which this measuring system is based Is as follows: The stiffness of the material can be computed from the kinematics measurd at touch down of a rigid body onto a material sample. The results show the following The result for the artifical surfaces(Synpave ace) is surprising. It is known that these surfaces are much harder than synpave rebound classic, synpave spring. This finding suggests that it may be possible that the subjective impression is used as one criterion in the selection of landing(or style) strategies. The number of subjects in this experiment is too small to make statistically significant conclusions. It is shown analytically that when an object a deformable surface, the acceleration it experiences is inversely propotional to its mass. In future, it need to stress that the interaction between shoe and surface is important, and this aspect has now become well accepted. Considering biomechanical aspect in player's injury, it request Korean Standards for synthetic playing surfaces in sport like ASTM(America Society for Testing & Materials) standards of America, DIN 18035 standards of Germany, BSI standards of U.K.
Experimental study on kinetic energy conversion of horizontal axis tidal stream turbine

<P><B>Abstract</B></P> <P>The present study aims to understand the energy conversion mechanism of a 100 kW horizontal axis tidal stream turbine by analyzing thrust, torque, and wake flow measurements. The scale ratio of the turbine model was 1/20 and model tests for power and wake measurements were conducted in a towing tank facility. Wake fields were measured by a towed underwater stereoscopic particle image velocimetry (SPIV) system. The chord-length based Reynolds number at 40% of the radius of the turbine ranged from 53,000 to 63,000 in the test conditions. The turbine model showed the highest power coefficient at a tip speed ratio (TSR) of 3.5, and the magnitude of power coefficient was 0.278. Three TSR conditions were selected for SPIV measurement after power measurement tests, representing heavy loading, highest efficiency, and light loading, respectively. In the wake field measurement results, conversion of kinetic energy of the turbine wake was investigated, decomposing it into effectively extracted work, loss due to the drag on the turbine system, kinetic energy of the time-mean axial flow, local flow structures, turbulence, and secondary flow loss. In high TSR conditions with a small angle of attack onto the turbine blade, the secondary flow loss was minimized.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Wake and force measurements of a HATST model were conducted in the towing tank. </LI> <LI> The measurements were characterized by a small blockage ratio and high Reynolds number. </LI> <LI> Energy conversion mechanism of a HATST was analyzed with measured data. </LI> <LI> Turbulence generation consumes only a small portion of the inflow kinetic energy. </LI> </UL> </P>

<P>We prepared a water-soluble conjugated polymer composed of electron-donating units and electron-accepting groups in the backbone. The polymer exhibits a short wavelength (blue) emission in aqueous solution and long wavelength (red) emission in the solid state, because of intermolecular energy transfer. Considering this, we develop a new approach for the sensitive detection of trypsin, which is known to control pancreatic exocrine function, using an ensemble system composed of the anionically charged conjugated polymer and cationically charged polypeptides (such as polylysine and polyarginine). The blue-emitting, water-soluble conjugated polymer becomes aggregated upon exposure to the polypeptides, leading to a red-emitting assay ensemble. The red-emitting assay ensemble becomes dissociated in the conjugated polymer and polypeptide fragments by selective degradation of trypsin, which then exhibits recovery of blue emission. This emission-tuning assay ensemble allows for detection of trypsin at nanomolar concentrations, which enables naked-eye detection. Importantly, this strategy can be employed for label-free, continuous assay for trypsin.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/aamick/2014/aamick.2014.6.issue-2/am405120y/production/images/medium/am-2013-05120y_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/am405120y'>ACS Electronic Supporting Info</A></P>

<P>We report a series of π-conjugated phenyltriene analogous molecules and crystals having different thiolated building blocks, which significantly influence the molecular ordering in the crystalline state. Whereas a polyene crystal having the methylthiolated phenyl (SM) building block exhibits a zigzag molecular ordering based on head-to-tail hydrogen bonds, the crystals of other analogues having the biphenyl sulfane (SB) block exhibit isomorphic crystal structures with herringbone packing. In one of these isomorphic crystals having both SM and SB building blocks, the herringbone packing is accompanied with head-to-tail hydrogen bonds. As a result of such packing promoted by SM and SB building blocks, the rigid phenyltriene bridge shows an unusual twisting and bending conformation, which is accompanied with a significant change of physical properties, such as fluorescent, linear, and nonlinear optical properties in the solid state.</P><P>We report a series of π-conjugated phenyltriene analogous molecules and crystals having different thiolated building blocks.
