Incentive education is a further requirement of our country's quality education concept for primary school Chinese education at the stage of compulsory education. Scientific incentive education can not only motivate students' learning enthusiasm, but also enable students to establish self-confidence and enhance willpower. This paper discusses the application of scientific incentive education in Chinese teaching in primary schools for reference.展开更多

The era of electricity also put his mark on the Romanian alveolus of civilization. The paper deals with an analysis of the scientific researches and applications which express the results of works of eminent scientists and engineers in electro-techniques and related domains, in Romania, in the first decade of interwar period 1919-1929. The scientific activities developed in many domains of Science are sustained by the significant technical progress in Romania, in this short but relevant period of Tempus in which, in Europe and in other parts of Civitas Terra, was peace.展开更多

Dataflow architecture has native advantage in achieving high power efficiency for scientific applications. However, the state-of-the-art dataflow architectures fail to exploit high parallelism for loop processing. To address this issue, we propose a pipelining loop optimization method （PLO）, which makes iterations in loops flow in the processing element （PE） array of dataflow accelerator. This method consists of two techniques, architecture-assisted hardware iteration and instruction-assisted software iteration. In hardware iteration execution model, an on-chip loop controller is designed to generate loop indexes, reducing the complexity of computing kernel and laying a good f（mndation for pipelining execution. In software iteration execution model, additional loop instructions are presented to solve the iteration dependency problem. Via these two techniques, the average number of instructions ready to execute per cycle is increased to keep floating-point unit busy. Simulation results show that our proposed method outperforms static and dynamic loop execution model in floating-point efficiency by 2.45x and 1.1x on average, respectively, while the hardware cost of these two techniques is acceptable.展开更多
