A GIS-based gradient analysis is a useful tool for exploring spatiotemporal dynamics of urban land-use. Although some case studies have been conducted confirming the efficacy this approach, large-scale regional urbanization has still seldom documented, and satellite cities their interactions with central city in also poorly explored. In study, combination remotely sensed data, metrics GISbased buffer employed to analyze overall characteristics expansion Shanghai region, China, explore its...
Long-term tracking tests revealed that the adaptive spiral profiling automatic rubber cutter is prone to “knife off” and jumping” states during cutting process. These issues result in inconsistent skin thickness poor surface uniformity can even damage natural trees, leading reduced yield, disease, potentially death. This paper presents experimental research on parameters affecting performance of cutter. It explores impact key establishes a mathematical model relating these peel rates....
A new Gray map between codes over F2 + uF2 u2F2 and is defined. We prove that the image of a linear (1-u2)-cyclic code length n binary distance invariant quasi-cyclic code. also that, if odd, then every which cyclic equivalent to
The ring Fp + uFp+ ··· +uk - 1Fp may be of interest in coding theory, which have already been used the construction optimal frequency-hopping sequence. In this work, cyclic codes over is an open problem posed [1] are considered. Namely, structure code and that their duals derived.
Active rectifier with comparators (CMPs) is often used in wireless power transmission (WPT) systems. However, it suffers from low conversion efficiency (PCE) light load condition and multiple pulse problem (MPP) due to the CMPs delay compensation. In this paper, a novel active time controller proposed solve both issues. A current control line (CCDL) introduced adjust rising falling edges of gate voltages NMOS (Fgns), controlled by negative feedback loop consisting switched-capacitor (SC)...
Students’ academic performance in chemistry can be the result of a number cognitive and affective factors. This study explored influence discipline-specific factors knowledge structure, perspectives, patterns on grade 9 students' performance. One instrument measured based concept knowing, application problem solving. Six tasks with marking keys patterns. Different groups students participated pilot tests field tests. The quality six was inspected by both expert assessment raters...
Radula hainanensis L.N.Zhang & R.L.Zhu sp. nov. (Radulaceae), a new species from Hainan Island of China, is described and illustrated. This can be recognized by the presence gemmae at apical dorsal margins leaf-lobes on ascending to erect shoots, thin-walled leaf cells with triradiate trigones, occurrence two different types oil bodies within each leaf-lobe cell. It superficially similar constricta, common in East Asia, which differs having larger leaf-lobules 1/2–2/3 as long leaf-lobes,...
Motivated by the work of Dougherty, Ling and Betsumiya, we define Type II codes over R = F2+uF2+u2F2 as self-dual with Lee weights a multiple 4. A new Gray map between F2 is defined. The existence code examined. Properties which take to are studied.
Abstract Assessing students' scientific literacy is necessary for science education policy, accountability and curriculum design implementation, there a need valid, reliable easy to use measurement instrument by local authorities. Based on the definition assessment framework of PISA, junior high school senior students was developed. The Rasch model used establish evidence validity reliability measures instrument. results showed that met expectations. Student achievement levels were defined...
Abstract The primary objective of science postgraduate education is to foster students' capacity for creative thinking and problem‐solving, particularly in the context scientific research quality. In order achieve this goal, “7E” teaching mood has been implemented cell biology course students promote student‐centered active inquiry learning instead breaking away from traditional indoctrination‐based methods. This study demonstrates that implementation mode, through content programming,...
This study is about issues and challenges of secondary school leaders are facing in China. It seen as presenting the following features: lack efficient funds a education which has become sector rapid growth with decentralization Ministry Education administration; run-off high quality teachers competitive market economy; lower teaching learning between dilemmas traditional exam--oriented new quality-oriented that being implemented Programme on Quality New Century aims at developing education....
The research group investigates 2,231 primary and middle school students from 11 schools in minority areas Northern Guangdong through questionnaires with occupying 43%.According to investigation results, terms of satisfaction infrastructure, home learning environment resources, course learning, motivation ideal, academic attribution, acceptance others etc, have generally smaller ethnic difference than gender stage difference; more significant many aspects; between male female is basically...
The research group made a survey on 11 schools in minority areas of northern Guangdong.In the questionnaire survey, totally 2,231 students from primary and secondary school are involved.According to result, learning environment & resources family, educational background parents absence family members will have an effect students' growth learning.Family is first for child, teachers child.Family has direct growth.There many factors influencing efficiency education.Through comparative analysis...
Cloud service is a model based on the Internet.In cloud support environment, we need to build for services of University learning.The design and application higher education system very important technology in field future.Based basic environment characteristics services, this paper constructs collaborative learning platform computer professional courses, university designed, problems shortcomings are discussed, scheme improved by experimental study, development has certain reference value...
