Moon Jong Han, Dong Ki Yoon

Engineering 2021, Volume 7, Issue 5,   Pages 564-580 doi: 10.1016/j.eng.2021.02.010

Abstract:

In the current shift from conventional fossil-fuel-based materials to renewable energy, ecofriendly materials have attracted extensive research interest due to their sustainability and biodegradable properties. The integration of sustainable materials in electronics provides industrial benefits from wasted bio-origin resources and preserves the environment. This review covers the use of sustainable materials as components in organic electronics, such as substrates, insulators, semiconductors, and conductors. We hope this review will stimulate interest in the potential and practical applications of sustainable materials for green and sustainable industry.

Optimum design of a channel roughened by dimples to improve cooling performance

Abdus SAMAD, Ki-Don LEE, Kwang-Yong KIM, Jin-Hyuk KIM,

Frontiers in Energy 2010, Volume 4, Issue 2,   Pages 262-268 doi: 10.1007/s11708-010-0012-2

Abstract: Staggered arrays of dimples imprinted on opposite surfaces of an internal flow channel have been formulated numerically to enhance turbulent heat transfer compromising with pressure drop. The channel is simulated with the help of three-dimensional Reynolds-averaged Navier-Stokes (RANS) analysis. Three non-dimensional design variables based on dimple size and channel dimensions and two objectives related to heat transfer and pressure drag have been considered for shape optimization. A weighted-sum method for multi-objective optimization is applied to integrate multiple objectives into a single objective and polynomial response surface approximation (RSA) coupling with a gradient based search algorithm has been implemented as optimization technique. By the present effort, heat transfer rate is increased much higher than pressure drop and the thermal performance also has shown improvement for the optimum design as compared to the reference one. The optimum design produces lower channel height, wider dimple spacing, and deeper dimple as compared to the reference one.

A prediction formula of water temperature released from the multi-level stop-log gate intake of hydropower

Gao Xueping,Chen Hong,Song Huifang

Strategic Study of CAE 2011, Volume 13, Issue 12,   Pages 63-67

Abstract:

In thermally stratified reservoir, a multi-level intake structure is usually adopted in hydropower station to reduce the negative effect of releasing lower-temperature water to the environment in downstream reach. And a simple and practical formula of water temperature released is need. In this paper, based on Nuozhadu Hydropower Station, a model test is conducted to model the thermal stratification of this reservoir, and measure the temperature of water released from the intake structure. A prediction formula of water temperature released is put forward based on the experimental data. The formula is validated by the experimental results of water temperature released from the intakes of Jinping No.1 Hydropower Station.

Abstract:

Cleft lip and palate (CLP) is the most common craniofacial congenital deformity.Sixty patients with unilateral complete cleft lip and palate were operated with this technique.The lip height, lip length, and relative height of the christa philtri were measured for symmetry evaluationThe difference observed in the lip height and lip length immediately after surgery became statisticallyinsignificant after 10 months (P = 0.104 for lip height and 0.121 for lip length).

Performance analysis of the stop-and-wait automatic repeat request protocol under Markovian interruptions Regular Papers-Research Articles

Dashdondov KHONGORZUL, Yong-Ki KIM, Mi-Hye KIM

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 9,   Pages 1296-1306 doi: 10.1631/FITEE.1700185

Abstract: The performance of an integrated packet voice/data multiplexer using a stop-and-wait (SW) automatic repeat request (ARQ) protocol is discussed. We assume that the input for the data traffic is exponentially distributed in increments via the Poisson process, with each data packet transmitted within an individual slot time. Another assumption is that there is only a single voice signal, which has a higher priority over the data packet, and whose traffic is given via an on-off Markov process. Whenever the voice signal is active, the output link is used and will be blocked for the data packet. We introduce the concept of buffer occupancy to simplify the analysis, and discover that data multiplexers using the SW ARQ protocol exhibit a behavior of queueing delay and buffering when the interruption signal is given via a Markov process. Simulation results verify the validity of the analytical results.

Liver surgery and transplantation in China: Progress and Challenges

LAU W Y, LAI E C H

Frontiers of Medicine 2007, Volume 1, Issue 1,   Pages 1-5 doi: 10.1007/s11684-007-0001-y

Abstract: From the limited but available information, we traced the history of developments of liver surgery and transplantation in China. Liver surgery first started in the late 1950s in China, and it soon flourished mainly because of the great demand in liver surgery and the emergence of a number of giants in liver surgery. We recognized and honoured the important contributions of these Chinese pioneers in portal hypertension, recurrent pyogenic cholangitis, hepatocellular carcinoma and liver transplantation.

Ground movements due to deep excavations in Shanghai: Design charts

VARDANEGA,Charles W. W. NG,Xianfeng MA

Frontiers of Structural and Civil Engineering 2014, Volume 8, Issue 3,   Pages 201-236 doi: 10.1007/s11709-014-0253-y

Abstract: Recent research has clarified the sequence of ground deformation mechanisms that manifest themselves when excavations are made in soft ground. Furthermore, a new framework to describe the deformability of clays in the working stress range has been devised using a large database of previously published soil tests. This paper aims to capitalize on these advances, by analyzing an expanded database of ground movements associated with braced excavations in Shanghai. It is shown that conventional design charts fail to take account either of the characteristics of soil deformability or the relevant deformation mechanisms, and therefore introduce significant scatter. A new method of presentation is found which provides a set of design charts that clarify the influence of soil deformability, wall stiffness, and the geometry of the excavation in relation to the depth of soft ground.

Robotized machining of big work pieces: Localization of supporting heads

Wojciech SZYNKIEWICZ, Teresa ZIELIŃSKA, Włodzimierz KASPRZAK

Frontiers of Mechanical Engineering 2010, Volume 5, Issue 4,   Pages 357-369 doi: 10.1007/s11465-010-0103-0

Abstract: A planner for a self adaptable and reconfigurable fixture system is proposed. The system is composed of mobile support agents that support thin sheet metal parts to minimize part dimensional deformation during drilling and milling operations. Compliant sheet metal parts are widely used in various manufacturing processes including automotive and aerospace industries. The main role of the planner is to generate an admissible plan of relocation of the mobile agents. It has to find the admissible locations for the supporting heads that provide continuous support in close proximity to the tool and trajectories of the mobile bases characterized by very high speeds during the relocation phases.
