Facing the challenges of programming courses teaching in university, this study constructs a precision teaching classroom for programming courses that integrates precision teaching theory. Firstly, ...this paper analyzes the realization conditions for precision teaching in programming courses, then designs the implementation process of precision teaching including three teaching phases and five teaching links, and finally carried out teaching practice in C Language Programming course. The practice results showed that in the precision programming teaching classroom, teacher-student interactions were more frequent and students had higher programming learning efficiency than in ordinary programming teaching classroom. Compared with the control class, students in the experimental class were more capable of grasping programming knowledge and had better programming problem-solving abilities, and most of them were highly satisfied with teaching design of precision teaching classroom for C Language Programming. Precision programming teaching classroom constructed by this research provides a more optimized and effective teaching method for university programming teaching. On the other hand, this study provides a practical case for the integration and application of precision teaching theory and university curriculum teaching.
The purpose of this book is to showcase a diverse set of directions in empirical research on mediated discourse, reflecting on the state-of-the-art and the increasing intersection between ...Corpus-based Interpreting Studies (CBIS) and Corpus-based Translation Studies (CBTS). Undeniably, data from the European Parliament (EP) offer a great opportunity for such research. Not only does the institution provide a sizeable sample of oral debates held at the EP together with their simultaneous interpretations into all languages of the European Union. It also makes available written verbatim reports of the original speeches, which used to be translated. From a methodological perspective, EP materials thus guarantee a great degree of homogeneity, which is particularly valuable in corpus studies, where data comparability is frequently a challenge. In this volume, progress is visible in both CBIS and CBTS. In interpreting, it manifests itself notably in the availability of comprehensive transcription, annotation and alignment systems. In translation, datasets are becoming substantially richer in metadata, which allow for increasingly refined multi-factorial analysis. At the crossroads between the two fields, intermodal investigations bring to the fore what these mediation modes have in common and how they differ. The volume is thus aimed in particular at Interpreting and Translation scholars looking for new descriptive insights and methodological approaches in the investigation of mediated discourse, but it may be also of interest for (corpus) linguists analysing parliamentary discourse in general.
C language is one of the most popular languages for software systems. In order to verify safety, reliability and security properties of such systems written in C, a tool UMC4M for runtime ...verification at code level based on Modeling, Simulation and Verification Language (MSVL) and its compiler MC is employed. To do so, a C program P has to be translated to an MSVL program M and the negation of a desired property Q is also translated to an MSVL program M', then “M and M'” is compiled and executed armed with MC. Whether P violates Q is checked by evaluating whether there exists an acceptable execution of new MSVL program “M and M'”. Therefore, how to translate a C program to an MSVL program is a critical issue. However, in general, C is of complicated structures with goto statement. In this paper, we confine the syntax of C in a suitable subset called Xd-C without loss of expressiveness. Further, we present a translation algorithm from an Xd-C program to an MSVL program based on translation algorithms for expressions and statements. Moreover, the equivalences between expressions and statements involved in Xd-C and MSVL programs are inductively proved. Subsequently, the equivalence between the original Xd-C program and the translated MSVL program is also proved. In addition, the proposed approach has been implemented by a tool called C2M. A benchmark of experiments including 13 real-world Xd-C programs is conducted. The results show that C2M works effectively.
One often wishes for the ability to formally analyze large-scale systems-typically, however, one can either formally analyze a rather small system or informally analyze a large-scale system. This ...paper tries to further close this performance gap for reachability analysis of linear systems. Reachability analysis can capture the whole set of possible solutions of a dynamic system and is thus used to prove that unsafe states are never reached; this requires full consideration of arbitrarily varying uncertain inputs, since sensor noise or disturbances usually do not follow any patterns. We use Krylov methods in this paper to compute reachable sets for large-scale linear systems. While Krylov methods have been used before in reachability analysis, we overcome the previous limitation that inputs must be (piecewise) constant. As a result, we can compute reachable sets of systems with several thousand state variables for bounded, but arbitrarily varying inputs.

In this note we classify the necessary and the sufficient conditions that an index of a superconformal theory in 3 ≤
d
≤ 6 must obey for the theory to have enhanced supersymmetry. We do ...that by noting that the index distinguishes a superconformal multiplet contribution to the index only up to a certain equivalence class it lies in. We classify the equivalence classes in
d
= 4 and build a correspondence between
N
=
1
and
N
>

equivalence classes. Using this correspondence, we find a set of necessary conditions and a sufficient condition on the
d

N

d

In analyzing various phenomena, actual numerical value acquired from measurement has to be utilized to obtain accurate analysis and judgment. However, while making measurements, it surely encounters ...error in measurement system, which will affect the accuracy of the results. In order to analyze more accurately, the error in measurement system must precede deeper detection. Nevertheless, in the past, error in measurement system detection mainly depends on manual way, and measurement data are substituted into the existed equation to get the results. Therefore, aimed at the system error, and reducing the complexity of error in measurement system detection and improving the analysis efficiency in our approach. And also based on C language GUI, to develop a computer toolbox with two significant kinds of evaluation criteria and utilize the actual case to verify the accuracy of the toolbox. It not only can quickly detect the errors in measurement system, but also can greatly decrease manual computation, which contrib
Digital information technology provides an innovative way for the obsolete and inefficient C language classroom. This paper applies computational thinking to the design of C language hybrid teaching ...and builds a task-driven model for teaching C language using a driven teaching approach. Digital information technology is applied to TDT teaching; test questions are dynamically extracted in the process of students’ tests, intelligently analyzed according to the student’s answers to the test questions, and a genetic algorithm is used to adjust the difficulty, differentiation and knowledge points of the group paper. Based on the hybrid similarity model, we optimize the mutation operation in the genetic algorithm and verify the effect of similarity calculation through the practice of grouping papers for C language teaching. Hybrid similarity yields weighted average similarity scores of test questions that are 0.14 and 0.16 higher than edit distance and cosine similarity, respectively. On the basis of similarity calculation, the time taken to improve the GA to generate the test paper is no more than 1 second, and the difficulty coefficient obtained does not differ from the expected coefficient by more than 0.05. The intelligent paper grouping method can maximize the coverage of the needs of more students and improve the investigation of C language teaching. The way of teaching C language.
The East Baltic languages are well known for their conservative phonology as compared to other Indo-European languages, which has led to a stereotype that the Balts developed in isolation without ...much contact with other speech communities. This book challenges that view, taking a deep dive into the East Baltic lexicon and peeling away the layers of prehistoric borrowings in the process. As well as significant contact events with known languages, the lexicon also reveals evidence of contact with unattested languages from which previous populations must have shifted.
