The gadget’s software applications nowadays appear to be highly popular and its use has been elevating among gadget users. This kind of technological advance also touched the Qur’anic learning process in Indonesia. On the one hand, not only does the emergence of Qur’anic learning software stimulate children’s interest, but it also provides a lot of features that will make children quickly understand and practice the Qur’anic reciting. On the other hand, this kind of learning method can threat the value of Qur’anic orthodoxy which had been applied among traditional Muslim societies since the emergence of Islam in Indonesia. Some resources have noted that there were some sacred values and courtesies perpetuated by traditional Muslims while teaching Qur’anic reciting. This article will track the historical journey of Qur’anic learnings in Indonesia and discuss how the emergence of Qur’anic Learning software (as the logical consequence of technological improvement) can threat the existence of some ancient orthodoxies toward the Qur’an.

Technological improvement is the most important cause of long-term economic growth. In standard growth models, technology is treated in the aggregate, but an economy can also be viewed as a network in which producers buy goods, convert them to new goods, and sell the production to households or other producers. We develop predictions for how this network amplifies the effects of technological improvements as they propagate along chains of production, showing that longer production chains for an industry bias it toward faster price reduction and that longer production chains for a country bias it toward faster growth. These predictions are in good agreement with data from the World Input Output Database and improve with the passage of time. The results show that production chains play a major role in shaping the long-term evolution of prices, output growth, and structural change.

Humanity is using mineral resources at an unprecedented level and demand will continue to grow over the next few decades before stabilizing by the end of the century, due to the economic development of populated countries and the energy and digital transitions. The demand for raw materials must be estimated with a bottom-up and regionalised approach and the supply capacity with approaches coupling long-term prices with energy and production costs controlled by the quality of the resource and the rate of technological improvement that depends on thermodynamic limits. Such modelling provides arguments in favour of two classically opposed visions of the future of mineral resources: an unaffordable increase in costs and prices following the depletion of high quality deposits or, on the contrary, a favourable compensation by technological improvements. Both views are true, but not at the same time. After a period of energy and production cost gains, we now appear to be entering a pivotal period of long-term production cost increases as we approach the minimum practical energy and thermodynamic limits for many metals.

Abstract Reclamation complexes, the key element of which are bypass canals, are actively used for effective agricultural work. For the development of reclamation canals. as a rule, excavator equipment is used, which subsequently ensures their effective functioning. The analysis of the impact of the efficiency of the functioning of amelioration systems on the agro-industrial complex (AIC) sectors revealed a significant dependence on obtaining high-quality crops or pastures. Factors were identified that reduce the quality of reclamation work. Among them, the indicator of positioning accuracy of the profile of the soil during clearing or arrangement of channels is highlighted as the main one. It was proved that the installation of automated leveling systems will provide technological improvement to the excavator. Modernization of excavators by introducing automatic leveling systems (ALS), allows you to increase the speed and accuracy of work, and therefore productivity. There are three main ALS solutions for excavator operation: ALS 2 D control system; ALS satellite monitoring system; ALS AUTO satellite leveling system. It was determined that for using ALS AUTO, the quality of the work performed does not depend on the human factor. Field tests were carried out at the test site with quality control of the construction embankments with JCB JS 205 excavator modernized with ALS. The data obtained were compared with the results of grading with a JCB JS 205 excavator without ALS. Based on the results of the data analysis, it was found that with the introduction of automatic leveling systems, the productivity of the equipment increases by 200%, and the accuracy of the work performed has increased 2 times.

Abstract: Electric Vehicle is widely used with its technological improvement. It is superior to internal combustion engines in efficiency and simplicity. Energy Storage System (ESS) is a heart of electric vehicle though it faces challenges in storage capability. This paper is about the evaluation of different energy storage options for electric vehicle including the batteries, super-capacitors, and flywheel. This paper conveys a review of the energy storage systems with challenges, opportunities and future guidelines of EVs with energy storage. Suggest some of the options under study to increase storage capacity. The comparison of energy storage system carried out with the help of its parameters such as energy density, specific energy, lifecycle, efficiency. Index terms- Energy Storage System, batteries, supercapacitors, Electric Vehicle, flywheel

The methods and some ways of technological improvement of the durability of internal screw surfaces are given. To increase the durability, finishing and strengthening machining with surface plastic deformation and threading with a cutter of a variable average diameter are proposed. The dependences for the specification of machining modes and the results of experimental studies of the screw surface quality parameters and wear resistance of running nuts are given.

This study intends to sort out what will be the normal choices of the customary financial frameworks and how the world economy will draw in and manage those normal other options. Since technological improvement is profoundly quick and momentous, it is imperative to comprehend the discernments, practices, correspondence, and the possibility of selection of those other options. Advanced monetary standards and cryptographic forms of money are non-customary financial monetary forms that depend on something referred to as blockchain innovation. There is an excessive number of advanced digital forms of money these days, all of them having their own attributes and specificities. A portion of those advanced digital currencies will be studied in this research. It is imperative to mention here that only one out of every odd nation acknowledges the progress in this area, and  such nations arrangement are often influenced by their World Bank rank — low, lower-middle, upper-middle, and high-income countries. More, this research looks at the social side of bitcoin and blockchain development in these nations. Bitcoin is tremendously influencing the economy overall. That’s why it quickly became of interest for many financially trained professionals and academicians. Unfortunately, this type of money has been increasingly used for criminal activities too. This research discusses all these sides as well as the important impacts bitcoin has on the population.

This paper examines the field of energy-based medical therapies based on the analysis of patents. We define the field as the use of external stimuli to achieve biomedical modifications to treat disease and to increase health. Based upon distinct sets of patents, the field is subdivided into sub-domains for each energy category used to achieve the stimulation: electrical, magnetic, microwave, ultrasound, and optical. Previously developed techniques are used to retrieve the relevant patents for each of the stimulation modes and to determine main paths along the trajectory followed by each sub-domain. The patent sets are analyzed to determine key assignees, number of patents, and dates of emergence of the sub-domains. The sub-domains are found to be largely independent as to patent assignees. Electrical and magnetic stimulation patents emerged earliest in the 1970s and microwave most recently around 1990. The annual rate of improvement of all sub-domains (12–85%) is found to be significantly higher than one we find for an aggregate pharmaceutical domain (5%). Overall, the results suggest an increasingly important role for energy-based therapies in the future of medicine.
