This approach is expected to foster the students' design skills in design studios. The approach is an educational tool for tutors that could guide the students and increase their creativity in their design. It considers the concepts and the practice of digital architectural design that influence architectural education. The approach is a catalyst for creativity, experimentation, critical thinking and the sustained growth of creative communities. The core of design studio is the notions, methods and skills of digital architectural design. The instruments used for this research was an investigation that made for the work of the fourth year students designs at the architectural department at University of Jordan, by testing design process and product of students' work: first using manual skills, and then using computer-aided programs. The results revealed that the computer-based design approach was able to foster students' design skills as well as to develop their creativity in design. Ninety-one percent of 44 students were found improved in design process using computer-based approach that depends on computer programs. This was done in design studio by improving students' way of thinking, developing their abilities to direct their own learning and pushing them for new definitions in developing their future work. 展开更多

The workload of the 3D magnetotelluric forward modeling algorithm is so large that the traditional serial algorithm costs an extremely large compute time. However, the 3D forward modeling algorithm can process the data in the frequency domain, which is very suitable for parallel computation. With the advantage of MPI and based on an analysis of the flow of the 3D magnetotelluric serial forward algorithm, we suggest the idea of parallel computation and apply it. Three theoretical models are tested and the execution efficiency is compared in different situations. The results indicate that the parallel 3D forward modeling computation is correct and the efficiency is greatly improved. This method is suitable for large size geophysical computations. 展开更多

Because of good quality of compressive resistance, the hyperbolic arch dam is being increasingly applied to engineering projects. In order to satisfy the needs of compressive resistance under the conditions of high water pressure, a stress analysis is required for the dam. During the stress analysis process however, due to the complexity of the three-dimensional modeling, it is very hard to form a model. Therefore, the stress analysis process is a barrier for the arch dam. In this article, based on the research of the new line-type arch dam, a mathematical model in different degree of convexity conditions of the dam is established; using the C + + language program, a computer three-dimensional model simulation is realized on AutoCAD. The accurate three-dimensional model is providing a finite element optimization design of the involute hyperbolic arch dam for the next step. 展开更多

The emissions trading scheme(ETS)is considered an effective policy tool for achieving emission reductions.At present,China's ETS pilots have completed several compliance periods and provided rich experience for a national ETS.Taking advantage of the variations in the regional ETS pilots across regions and sectors and over time,this study used a difference-in-difference-in-differences(DDD)model to examine the effects of ETS pilots and differential program design on industry risk and the impacts of risk on future investment horizon.First,we found that the ETS pilots significa ntly increase profit variability(total risk)in China's industry;that is,ETS in duces greater uncertainty in the covered sectors.In terms of industry heterogeneity,non-eleclricily sectors(specifically ferrous metal)engage in higher levels of risk taking.Second,the influence of such program features as the allowance allocation(total amounts and approaches),China Certification Emission Reduction(CCER)trading volumes,and penalties are heterogeneous.Finally,during the period around the treatment,industry risk can significantly encourage longer rather than shorter investment.In particular,the punishment mechanism and benchmarking allocation play a positive role in regulating the risk-investment relationship. 展开更多

Based on the improved particle swarm optimization(PSO) algorithm,an optimization approach for the cargo oil tank design(COTD) is presented in this paper.The purpose is to design an optimal overall dimension of the cargo oil tank(COT) under various kinds of constraints in the preliminary design stage.A non-linear programming model is built to simulate the optimization design,in which the requirements and rules for COTD are used as the constraints.Considering the distance between the inner shell and hull,a fuzzy constraint is used to express the feasibility degree of the double-hull configuration.In terms of the characteristic of COTD,the PSO algorithm is improved to solve this problem.A bivariate extremum strategy is presented to deal with the fuzzy constraint,by which the maximum and minimum cargo capacities are obtained simultaneously.Finally,the simulation demonstrates the feasibility and effectiveness of the proposed approach. 展开更多

Over the past two decades,China has introduced significant changes to drug regulations through regulatory innovations to accelerate drug review and approvals,keeping in line with the rapidly growing scientific innovation in drug research and development(R&D).In this study,we outlined the revolution of drug regulation in China since the establishment of the State Drug Administration in 1998.More particularly,we performed a comprehensive analysis of newly approved anticancer drugs in China from the year 2005 to May 2021,as a powerful illustration of how the revolution has changed the drug R&D landscape.Innovative drug development in China has boomed,benefiting in particular from pro-innovation policies as well as expedited program designations by the authority.We found a significant increase in the number of both imported and domestic new anticancer drugs from 2005 to 2021,with the emergence of drugs with novel mechanisms of action,including immune checkpoint inhibitors and cell therapy products.Drug lag has also been dramatically shortened by more than 70%for imported drugs in years 2016-2020 compared to years 2006-2010.Furthermore,we provide an insight into the potential approaches to further optimize the science-based and clinical value-based regulatory and R&D drug ecosystem in China.This review provides evidence of significant impacts of regulations and policies on drug R&D and suggests that the constantly adapting regulatory ecosystem will speed up drug development in China and worldwide. 展开更多

The GAMMA paradigm is recently proposed by Banatre and M6tayer to describe the systematic construction of parallel programs without introducing artificial sequentiality. This paper presents two synchronous execution models for GAMMA and discusses how to implement them on MasPar MP-1, a massively data parallel computer. The results show that GAMMA paradigm can be implemented very naturally on data parallel machines, and very high level language, such as GAMMA in which parallelism is left implicit, is suitable for specifying massively parallel applications. 展开更多

Software defect prevention is an important way to reduce the defect introduction rate.As the primary cause of software defects,human error can be the key to understanding and preventing software defects.This paper proposes a defect prevention approach based on human error mechanisms:DPe HE.The approach includes both knowledge and regulation training in human error prevention.Knowledge training provides programmers with explicit knowledge on why programmers commit errors,what kinds of errors tend to be committed under different circumstances,and how these errors can be prevented.Regulation training further helps programmers to promote the awareness and ability to prevent human errors through practice.The practice is facilitated by a problem solving checklist and a root cause identification checklist.This paper provides a systematic framework that integrates knowledge across disciplines,e.g.,cognitive science,software psychology and software engineering to defend against human errors in software development.Furthermore,we applied this approach in an international company at CMM Level 5 and a software development institution at CMM Level 1 in the Chinese Aviation Industry.The application cases show that the approach is feasible and effective in promoting developers' ability to prevent software defects,independent of process maturity levels. 展开更多
