The novel coronavirus disease 2019 (COVID-19) has spread globally and the meteorological factors vary greatly across world. Understanding effect of control strategies on COVID-19 transmission is critical to contain epidemic. Using individual-level data in mainland China, Hong Kong, Singapore, number confirmed cases other regions, we explore temperature, relative humidity, measures COVID-19. We find that high temperature mitigates disease. High humidity promotes when low, but tends reduce...
Purpose This study aims to clarify the effect of team effort allocation between knowledge exploration and exploitation on generation extremely good or poor innovations. The influence previous collaborative experience among members is also investigated understand relationship members’ collaboration networks learning. Design/methodology/approach uses data all patents granted by US Patent Trademark Office 1984 2010. inventors involved in a patent are regarded as focal team. Logistic regression...
Parallel machine scheduling problems are commonly encountered in a wide variety of manufacturing environments and have been extensively studied. This paper addresses makespan minimisation problem on identical parallel machines, which the specific processing time each job is uncertain, its probability distribution unknown because limited information. In this case, deterministic or stochastic model may be unsuitable. We propose robust (min–max regret) for identifying schedule with minimal...
Recently, there has been a growing interest in applying the design structure matrix (DSM) for planning projects that consist of many interrelated activities. One important objective is to find an activity sequence so as minimize sum superdiagonal numbers DSM. It known problem NP-complete and difficult solve. In this study, we prove several structural properties problem, propose heuristic obtaining good feasible solutions. We based on fold operation, block activities can be treated single...
Production and manufacturing systems often involve a myriad of interrelated activities. How these activities are organised scheduled has significant effect on the success system. Recently, Design Structure Matrix (DSM) been regarded as an effective tool for modelling scheduling Based fuzzy set theory, this study explicitly addresses uncertain activity dependencies in our formulation develops mathematical model sequencing DSM. Because complexity model, new approach, which embeds exact...
An important decision problem faced by design managers is identifying an appropriate sequence of many interrelated activities. This study presents effective tool for determining the activity with minimum total feedback length in a structure matrix. can be modeled as linear ordering quadratic objective function and extremely difficult to solve even small instances. We first transform this into two equivalent integer programming problems, which solved exactly when number activities not large....
In recent years, information and communication technologies (ICTs) have significantly affected the outcomes of large-scale collective actions. addition, there is a well-known theoretical proposition that ICTs can fuel action by increasing individuals’ social connectivity closely related to recruitment capacity. This study aims test this examining two moderating factors: cultural context (i.e., online patterns) political distribution preferences). By utilizing agent-based modeling, we find...
With the increasing demand for transmission capacity on optical fiber trunk lines, ultra-long 40Gb/s per-channel all systems are now becoming very attractive [1-3], as they offer high signal spectral efficiency and large with a smaller number of channels, at potentially lower cost.
3.08 Tbit/s (77 × 42.7 Gbit/s) WDM transmission over 1200 km fibre with 100 amplifier spacing and GHz channel is demonstrated. Error-free of all 77 channels achieved by employing dual C- L-band hybrid Raman/erbium-doped inline amplifiers, experimental low dispersion slope TrueWave® fibre, forward error correction.
We present S-band Raman amplifiers that compensate both dispersion and span loss using distributed discrete amplification over 1488ñ 1518 nm. transmitted 40 × 10 Gb/s 6 100 km of a prototype True WaveÆ fiber.
The issue of scheduling interrelated activities is important and particular concern to design managers. One tool that helps us solve this the structure matrix (DSM) which can explicitly represent information dependencies among activities. Based on DSM method, study presents effective approaches for sequencing with goal minimizing total feedback length, a good approximation reducing project completion time. First, we prove two new properties problem, develop an insertion-based heuristic....
We have for the first time to our knowledge demonstrated a single mode dispersion compensating fiber with low PMD, loss and high Raman gain. The can compensate as well slope of NZDF RDS 0.018 nm/sup -1/. importance matching not only but also curvature has been new residual is measured /spl plusmn/0.02 ps/(nm km) in wide band from 1520 1580 nm facilitating 40 Gbit/s transmission more than 3000 km no individual channel correction.
Concurrent product development, the practice of executing dependent development stages simultaneously, has become common mode new because increasing importance time-to-market. However, such simultaneous execution may substantially increase total amount rework. This research addresses trade-offs involved in concurrent process, presents analytical models to determine optimal priority ordering initial and rework, overlapping duration. We first show that is prior rework when learning effect...
Error-free transmission of eighty 40-Gb/s, 100-GHz spaced channels over 2000 km TrueWave/spl reg/ REACH fiber is achieved. We employ 100-km all-Raman-amplified spans, dispersion-slope-matched dispersion compensating modules covering a 75-nm band, carrier-suppressed return-to-zero modulation format, and forward error correction.
