With the application of the dynamic control system, Cellular Automata model has become a valued tool for the simulation of human behavior and traffic flow. As an integrated kind of railway signal-control pattern, the four-aspect color light automatic block signaling has accounted for 50% in the signal-control system in China. Thus, it is extremely important to calculate correctly its carrying capacity under the automatic block signaling. Based on this fact the paper proposes a new kind of "cellular automata model" for the four-aspect color light automatic block signaling under different speed states. It also presents rational rules for the express trains with higher speed overtaking trains with lower speed in a same or adjacent section and the departing rules in some intermediate stations. In it, the state of mixed-speed trains running in the section composed of many stations is simulated with CA model, and the train-running diagram is acquired accordingly. After analyzing the relevant simulation results, the needed data are achieved herewith for the variation of section carrying capacity, the average train delay, the train speed with the change of mixed proportion, as well as the distance between the adjacent stations.

The internet service is provided by a given number of servers located in the main node of internet service provider (ISP). In some cases; the overload problem was occurred because a demand on a given website goes to very high level. In this paper, a fuzzy logic control (FLC) has proposed to distribute the load into the internet servers by a smart and flexible manner. Three effected parameters are tacked into account as input for FLC: link capacity which has three linguistic variables with Gaussian membership function (MF): (small, medium and big), traffic density with linguistic variables (low, normal and high) and channel latency with linguistic variables (empty, half and full); with one output which is the share server status (single, simple and share). The proposed work has been simulated by using MATLAB 2016a, by building a structure in the Fuzzy toolbox. The results were fixed by two manners: the graphical curves and the numerical tables, the surface response was smoothly changed and translates the well-fixed control system. The numerical results of the control system satisfy the idea of the smart rout for the incoming traffics from the users to internet servers. So, the response of the proposed system for the share of server ratio is 0.122, when the input parameter in the smallest levels; and the ratio is 0.879 when the input parameters are in highest level. The smart work and flexible use for the FLC is the main success solution for most of today systems control.

Abstract The internet can be made as a way to transfer knowledge from lecturers to students, while Learning that utilizes the internet is one of the E-Learning Learning media. E-learning is distance learning that utilizes computer technology or computer networks or the Internet E-learning, so that it can enable the learning process through computers in their respective places without having to physically go to attend classes or lectures in class, Systems e-learning learning is a new way of teaching and learning. E-learning as a special learning media PAI courses provide a very important role and a large function in the course because so far there are many shortcomings and weaknesses such as the limitations of space and time in the teaching and learning process through E-learning which prioritizes the efficiency of learning so students get full teaching even though they do not have to be face to face, can also be accessed anywhere, anytime, according to the assignments given by the lecturer usually scheduled with a specified deadline. The development of education towards e-learning is a must so that the quality standards of education can be improved, E-learning is one of the uses of internet technology in the delivery of learning and its broad reach. E-learning can also be an answer to a health problem that is Pandemic Corona (Covid-19) which is very influential also in every aspect of life, especially in education.Keywords: Effectiveness, Utilization, Islamic Religious Education, E-Learning, Covid 19. Abstrak Internet dapat dijadikan cara untuk mentransfer ilmu pengetahuan dari Dosen kepada mahasiswa/mahasiswi. Adapun Pembelajaran yang memanfaatkan internet salah satunya adalah media pembelajaran E-Learning. E-learning adalah pembelajaran jarak jauh (distance learning) yang memanfaatkan  teknologi komputer atau jaringan komputer atau internet E-learning, sehingga dapat  memungkinkan proses pembelajaran melalui komputer di tempat mereka  masing– masing tanpa harus secara fisik  pergi  mengikuti pelajaran atau pun  perkuliahan di kelas,  Sistem pembelajaran e-learning adalah cara baru dalam proses belajar mengajar. E-learning  sebagai   media pembelajaran khususnya mata kuliah PAI memberikan  peran   sangat   penting  dan fungsi yang besar pada mata kuliah tersebut karena selama  ini terdapat banyak  kekurangan  dan kelemahan seperti keterbatasan ruang dan waktu dalam  proses belajar  mengajar melalui E-learning yang  mengedepankan keefisienan dalam belajar sehingga  mahasiswa mendapat pengajaran yang penuh meski tidak harus bertatap muka, juga bisa di akses di mana saja, kapan saja,  sesuai dengan tugas yang diberikan oleh dosen biasanya terjadwal dengan  batas  waktu  yang  di tentukan. Pengembangan  pendidikan menuju e-learning merupakan suatu keharusan agar standar mutu pendidikan dapat ditingkatkan,  E-learning merupakan salah satu penggunaan teknologi internet dalam penyampaian  pembelajaran  serta  jangkauannya yang luas. E-learning  juga dapat menjadi jawaban dari suatu permasalahan kesehatan yaitu Pandemi Corona (Covid-19) ini yang sangat berpengaruh juga pada setiap aspek kehidupan terutama bidang pendidikan.Kata kunci  :  Keefektifitas, Pemanfaatan, Pendidikan Agama Islam,  E-Learning, Covid 19.
