Computer basic teaching is an essential basic learning content in higher education teaching. In order to encourage students and enable them to practice and improve their programming ability, the online judge system has been introduced into the programming course for compiling, executing and evaluating the algorithm source code submitted by students. The asymmetry of students’ programming level is an important issue when teachers guide the programming of online judge system. We used the exploratory factor analysis method to identify the potential variable structure from the log data submitted by the students of the online judge system, and evaluate the programming level of the students to predict the “at risk” learners. We proposed a student participation model, SCFH, based on this variable structure. Using the log data of the students in the C language course and their final exam results, we trained a deep neural network based on SCFH to divide the students into three different grades, namely “risky”, “intermediate” and “advanced”. To verify the validity of the model, we used the prediction model to classify students in another C++ language programming course. The results show that the submission log data model SCFH can be used to predict the programming ability of students, and the validity of these results can be tested by examination results.

Islamic Jurisprudence

Islamic jurisprudence is a dynamic system. It is facilitated by some flexible methodologies. Nowadays, there are varieties of issues in Muslims’ societies that are results or implications of developments in science and technology, and also results of changes that happen in the structures of the societies. In order to face these realities, a contemporary integrative approach has to be applied in Islamic Law's research process. In accordance to this, this paper will elaborate the integrative approaches that try to unify and integrate theories in Islamic jurisprudence with social research methods. Basically, there are models that have been introduced by several Islamic thinkers that related to this integrative approach. For example the Islamization of sociology based on maslahah model, the Islamic Jurisprudence sociology model, the unified approach to textual and contextual analysis model. All of these models contain their own strength and weakness in their integrative approaches. This paper is trying to introduce an approach that integrates Islamic jurisprudence theories with the gender analysis method that is among social critics methods. This introduced method is to be used to analyze an issue in fiqh pertaining to polygamy that is always been debated nowadays and also to analyze the applicability of the practice in the social and contemporary conditions of our country. According to this research, social research methods are able to support Islamic jurisprudence in order to improve its research process and its results. Keywords: integrative approach, Islamic jurisprudence, social science, gender analysis, polygamy   Hukum Islam merupakan satu sistem dinamik yang dibangunkan berasaskan metodologi yang bersifat anjal. Pada hari ini, wujudnya pelbagai isu yang melanda masyarakat umat Islam kesan daripada perkembangan sains dan teknologi serta perubahan sosial yang berlaku dalam struktur masyarakat.

This paper proposes an exergoeconomic analysis method that considers environmental costs to make up for the lack of description of environmental costs in the traditional matrix model exergoeconomic analysis method. This method tracks the formation process of the product cost through life cycle and makes a useful exploration for revealing the true cost of the system product. According to actual needs, the principles for the construction of environmental emissions of products are proposed, and a detailed exergoeconomic analysis model is established by taking the iron smelting system as an example. Through calculation and analysis, the formation process and change rule of unit exergoeconomic cost of products in the system are revealed. Especially, considering the exergoeconomic cost of carbon emissions, the results show that the three most influential substances are sinter, coke, and pellets. When carbon dioxide emissions are considered, the total cost will increase by 165.3 CNY/t iron, and unit exergoeconomic cost gradually increases with the progress of the production process.

The HEP community is preparing for the LHC’s Run 3 and 4. One of the big challenges for physics analysis will be developing tools to efficiently express an analysis and able to efficiently process the x10 more data expected. Recently, interest has focused on declarative analysis languages: a way of specifying a physicists’ intent and leaving everything else to the underlying system. The underlying system takes care of finding the data - powering the event processing loop – and even exactly how to most efficiently apply a desired jet selection. If this works, this would allow an analyser to test their algorithm on a small amount of data on their GPU-less laptop and then run it on a large amount of data on a server with multiple large GPU’s without having to alter their code. The LINQToROOT project, started almost seven years ago, fits this model. It has been used and tested in three ATLAS published analyses. LINQToROOT is based on the Language Integrated Query system built into the cross-platform C# language. It enables writing strongly-typed queries on a ROOT’s TTree’s data and transcribes the data to a C++ algorithm that can run in ROOT. Recent work on this system has had two goals: improving analysis efficiency and better understanding the requirements of a declarative analysis language. For example, a good analysis language should be able to abstract away the backend – recent work has increased the possible back ends from formerly the single Windows ROOT backend to one that runs on Linux, the Windows Linux-subsystem, and an experimental one that allows for PROOF like parallel processing – all done with almost no change to the analysis code itself. Any analysis language must also be rich enough to support an experiment’s data model. To test this, some experiments with the full ATLAS xAOD data model have been performed. All of this has been done while attempting to keep the project close to its original goals: quick turnaround for real ATLAS physics analysis. This work will be discussed in some detail along with thoughts and lessons that have helped shape our thinking about an Analysis Language and perhaps our approach to future physics analysis employing declarative analysis.
