/in /by

Digit Recognition in real time through hand gestures has achieved great attention in machine learning and computer vision applications. This article focuses on identifying Bangla numerals in the air using hand motions. This research leads to the stairwell, allowing for more investigation in the same subject for various Bangla characters and even phrases. The major issue, however, is coping with the wide range of handwriting styles employed by various users. Many studies have been done on the identification of Bangla handwritten digits, but none has proven successful at recognizing Bangla digits in real time using hand gestures in the air. As a result, this article describes the creation of a Bangla digit recognition model that employs a Convolution Neural Network (CNN) to predict Bangla digits by observing hand movements in the air space.  After a thorough examination, the suggested system attained a 98.37% accuracy on the BanglaLekha-Isolated dataset.

Indonesia is one of the countries that focuses on infrastructure development to support the areas of connectivity and accelerate economic growth while maintaining the global commitment to GHG emission reduction. In order to support the above objectives, competitive bitumen prices with less GHG emissions are foreseen for the infrastructure’s development. Polymer Modified Bitumen (PMB) is one of the materials that is used for the pavement application that could provide 16.99% less GHG emissions compared to the unmodified bitumen due to their capability to provide similar performance with the thinner pavement layer requirement. There are 3 common PMB production processes recognized in the industry, such as Low Shear Mill Technology, High Shear Mill Technology, and Mobile PMB Plant. The Capital Budgeting technique (NPV, IRR, Profitability Index, Payback Period), internal and external analysis such as PESTEL and Porter’s five forces analysis are used to support the decision making for the right technology selection for the PMB processing plant in order to stay competitive in the Bitumen market. The economic analysis has shown that the low shear technology generates an NPV of IDR 186.573.816.286 with an IRR of 75,90%, the high shear technology generates an NPV of IDR 179.179.736.676 with an IRR of 62,39% and the mobile PMB plant generates an NPV of IDR 243.276.282.784, with an IRR of 68,37%. In addition to the highest NPV, the mobile PMB plant has the full flexibility to be mobilized to any project location, especially in remote areas where other production technologies are not available. Based on the above analysis, the mobile PMB plant is the right technology to be selected for the PMB provision to support the infrastructure development in Indonesia.

Premium on a Budget: Second-hand iPhones in Indonesia

/in /by

Apple, as one of the major players in the global smartphone market, does not have a strong position in the market but there are unique patterns found in the iPhone market in Indonesia as the second-hand market is thriving, although the newer iPhones keep releasing annually. This research is trying to explore the uniqueness of the Indonesia market through several interviews conducted and observation. Through analysing the company’s internal capabilities and market conditions in Indonesia, it is found that despite the annual changes, Apple has preserved the older iPhone due to longer life cycle support by the company, releasing the older iPhones as ‘cheaper versions’ at discounted prices as the part of strategy to maintain the premium images of iPhones. This strategy not only meant to increase the sales of iPhones, but also to increase the consumer base of the iOS product as the iPhone was considered a gateway of the Apple software and product ecosystem. The buyer desired to have the iOS experience on a budget. However, most second-hand iPhones in Indonesia were not registered under Indonesian authorities which could potentially be blocked by the Indonesian government and buyers’ concern about the used quality product. Solutions proposed for the Indonesian market meant selling the certified refurbished iPhone that officially shipped to Indonesia as the budget iPhone options with better quality control to ensure the consumer’s peace of mind.

Written and Spoken Language in Igbo Cultural Milieu: A Philosophical Approach

/in /by

Aristotle in his De Interpretatione sketches how words are related to things through the mind. It is the spoken word that brings to light the secret intentions of the human heart. Hence the Igbo people usually say that the spoken word is the human mind made visible.  In our contemporary society, the effects of many related spoken word problems are often misconstrued as either attacks from the malevolent spirits or as the machinations of the evil people. The spoken words can create as well as destroy. There is, therefore, a serious need to create the awareness and enlightenment in this regard to the grassroots. This work will, therefore, attempts to bring out the concept of the spoken language in Igbo cultural milieu, as a phenomenon to a philosophical scrutiny and, hence to provide the much needed literature in the field. Hence, the work intends to bring some enlightenment concerning the Igbo concept of the spoken words. This enlightenment will as well create awareness on the effectiveness and efficaciousness of the spoken words both in the positive and the negative dimensions, as well as the reason Igbo-African prefer spoken words to the written words. The researcher primarily uses philosophic techniques as a method to achieve the purpose of the study.
