METHODOLOGY FOR DEVELOPING A HIGH-SPEED COMPILER BASED ON THE MODIFIED LOOP FUSION OPTIMIZATION METHOD: MODELS AND TOOLS FOR ITS IMPLEMENTATION

In connection with the development of information technologies, the complexity of programming languages and, accordingly, applications developed using them, program optimization is of particular importance. In the process of optimization, the program is improved by reducing the code size, complexity, using less memory and provides a reduction in execution time without changing the internal function. In practice, optimization is implemented using compilers and their functions. Taking into account the above, the aim of the article was to develop a methodology for studying various aspects of building a high-speed compiler with a modified loop fusion optimization method, as well as models and tools for its implementation. In the course of the research, the features of its design using the modified loop fusion optimization method are outlined, descriptions of the flowchart of the modified loop fusion algorithm and the logical flowchart of the compiler development stages are given. As a result of the work, a compiler based on the modified loop fusion optimization method is proposed, using loop reversal to ensure their “legitimate” and profitable merging, which reduces the execution time of the program while maintaining its correctness. The efficiency of the proposed compiler is shown by comparing the compilation times of the test program obtained using it and using the well-known compiler x86-64 gcc 4.7.1.

Context-sensitive parsing for programming languages

Parsing programming languages using context-sensitive rather than context-free grammars is being considered here because a stronger formalism might be beneficial for dealing with increasingly complex programming languages and their syntax, or is more appropriate in some applications. A new deterministic non-backtracking algorithm for parsing deterministic context-sensitive languages is described. It is a significant improvement of the algorithm built into WEAVE and CWEAVE tools for literate programming and requires that the language is described by a context-sensitive reduction system, namely a deterministic formalism similar to a context-sensitive grammar but with strict rules about how reductions are to be applied. The new algorithm uses a reduction automaton for finding the position of the next reduction at each step during parsing rather than a hardcoded trie that is build into the original algorithm of WEAVE and CWEAVE. The new algorithm performs at least twice as few operations per input symbol as the original one. Furthermore, it is shown that parsing a language described by a context-sensitive reduction system need not be limited to typesetting purposes as in literate programming but can be used as a general parsing approach.

CMS Wordpress Based Academic Information System Design at SMPN 17 Marusu

School is one of the formal education facilities that must be able to provide the best services or facilities for students and also for parents. One of the right ways is to use information technology, namely accessing academic values through websites. The specific objective of this research is to produce an academic information system based on Wordpress Content Management System (CMS) that can be used by SMPN 17 Marusu in Maros Regency. The current website-based academic information system is made using a complex programming language and requires special skills to create the website. Wordpress is a platform for creating websites instantly. In this study, the information system was built using the prototype method so that it can be adapted to user needs. The resulting software is presented to the user, starting from the requirements analysis, design to implementation stage, and users are given the opportunity to provide input so that the resulting software really fits the user's needs. The prototype method consists of several stages, namely, requirements analysis, system analysis, system design, system testing, and system implementation. The design stage includes interface design, front end and back end using WordPress CMS. With this school website, it is hoped that it can help government programs in improving school performance and productivity.

A Study of Teaching Problem Solving and Programming to Children by Introducing a New Programming Language

Technology has been growing rapidly, and this fact that computers, gadgets and electronic devices have become part of our life is deniable. Computer skills and programming languages have become as important as other essential subjects in schools. Researchers have done some researches in the area of teaching programming and problem solving to novices, this study aims to study whether it is necessary to teach problem solving and programming in early ages. This study also aims to review previous studies in this area. We attempt to introduce a new programming language which has been developed to simplify the method of learning and coding for novices and young learners. We have been developing a new programming language which the children and young learners considered to be the learners of this language; however professional programmers would be able to code with this language as well. There are many popular and powerful languages, Python for instance is easy to understand and code with, however it is still complex and difficult to learn for children, and on the other hands programming languages like Java and C++ have their complexity. The target users are children who have no knowledge about programming. Beside some inappropriate teaching methods and resources, the complexity of programming languages and lack of knowledge about problem solving, young learners find programming terrifying. Having a programming language with a simple syntax and methods will encourage students and failure ratio will be decreased. Children will have a chance to learn how to code and solve a problem by using and interacting with an easy programming language. By doing this research and using valuable resources, we would expect to have positive and effective changes in science and programming in near future, as the today’s children are the future of our society.

OOPNET: An object-oriented EPANET in Python

Several attempts of the past aimed to convert EPANET into a bigger open-source project by rewriting EPANET in an object-oriented way. We introduce a Python based object-oriented EPANET (OOPNET) with the purpose to address water engineers that might be not so familiar with complex programming languages like C++ or Java. EPANET input files are translated into the object oriented structure of OOPNET and manipulated and simulated with EPANET's command-line interface through Python. The replacement of EPANET by a hydraulic solver in Python is still ongoing and has the purpose to provide a solution completely written in one programing language.

Computer-assisted analysis of intrapartum cardiotocodynagraphs

To develop a numerical index by quantifying characteristic cardiotocography parameters in order to determine the intrauterine state of the fetus sub partu with sufficient accuracy to improve the diagnostic potential of cardiotocography. This score is then computerized for offline and online analysis. The last 120 minutes of 406 directly recorded intrapartal cardiotocograms (CTG) were evaluated with a magnifying glass on the basis of conventional criteria. The mean basal frequency, the amplitude and the oscillation frequency of each individual baseline minute, the decelerations with depth, duration and type classification as well as the accelerations were determined. The Apgar score and the measurements of blood gases in the umbilical arterial and venous blood served as outcome parameters. The actual pH in the umbilical artery (UA) was the key variable. The newly developed CTG score was converted into a complex programming language after meticulous statistical testing and prepared for offline and online use. A score which is based on the CTG characteristics basal frequency level, baseline fluctuation and total decelerations area was developed on the basis of about 40 000 baseline minutes and more than 8 000 analysed decelerations from 406 fetuses which were all vaginal deliveries with a rate of acidosis (pH,UA < 7.100) of 9.8 % (deliberate selection). This score correlates highly significantly (r = -0.5752) with the actual umbilical arterial pH (p < 0.001). The correlation with the Apgar score (1 min) is r = -0.398, p < 0.001. The positive likelihood ratio (score 9) is 11.0 (95 % confidence interval 7.4-16.5) indicating that the test is very reliable. The score could be prepared for offline analysis of electronically registered CTGs with the assistance of a mathematician, so that the obstetrician's "eye work" can be dispensed with entirely. This program written in "C" also enables online evaluation of fetal heart rate patterns over time and a representation of the output parameters with acoustic and optical warning display options appropriate for the delivery room. Quantitative registration of fetal heart rate phenomena during delivery can be accomplished successfully by means of a score. The score correlates highly significantly with the actual pH value (UA) and the Apgar score (1 min). It is suitable both for offline and online analysis of intrapartal CTGs, and offers the prospect of quantitative fetal online monitoring.

A general robot control system for automatic chemical analysis

Advances in instrumentation have led to increasing interest in automatic chemical analyses. Unfortunately, the potential flexibility of robot systems can often not be exploited because of complex programming languages and poor user-interface. These factors generally limit the use of laboratory robots to a few repetitive tasks. This paper describes the development of a general robot control system for automatic chemical analysis. The program is written in Turbo Pascal and Visual Basic and runs in the Microsoft Windows environment. The analytical workspace is designed by selection of an object's icon followed by its desired orientation. Positioning of this object is then performed using a ‘drag and drop’ procedure. The robotic procedure is set-up by selection of items of apparatus and their associated actions. The performance of the system is demonstrated by the determination for caffeine in tablet formulations using a continuous dilution and calibration scheme.
