Authors: S Salim S , Jainuddin  , Darmawan F A 
Published: May 2021

Abstract
Students working on a word problem sometimes missed the answer for some reasons. The most common reason is that the students misinterpreted the question. Word problems sometimes mention a vocabulary that is somewhat difficult to define by the students. Besides, word problems, especially algebra word problems, are not easy to be visualised because the comparative vocabularies used are confusing for some students. As a result, they end up with incorrect conclusions instead. As such, this study aims to create augmented reality-based student’s worksheets to assist the students to visualise algebra word problems using animations. This is a design and development study, which consists five stages. The first stage is investigating students’ needs (amid covid-19 pandemic in particular). After that, the augmented reality-based student’s worksheets are designed by considering the investigating result. Next, the worksheets are constructed before being tested and evaluated. Based on the evaluation, the worksheets are revised then finally it is ready to be implemented. The recent progress of the research is that the augmented reality-based student’s worksheets has been revised and ready to be implemented. The worksheets allow students to study from home by scanning codes using their devices (android smartphones are advised) then video animations will appear and explain the algebra word problems they are working on.

Published: May 2021

Abstract
String matching algorithms are critical for web usage devices which screen the packets and moves on the basis of load. Intrusion detection or prevention systems, web cleansing, anti-virus and junk preventive systems all have a necessity for effective algorithms when managing string matching scenarios. Some of the algorithms viz. Aho-Corasick, WuManber, Rabin-Karp, Commentz-Walter, Bit parallel etc. entails lot of space and time. AhoCorasick algorithm is built on the basis of finite state machines. On the shadow of KnuttMorris-Pratt, Commentz Walter developed an algorithm which in turn uses finite state machines. Bit parallel algorithms like shift-or takes the help of varied computer words ie. the registers in CPU, to compare the efforts. Rabin Karp implements hashing for discovering matching pattern strings in a given text. Wu-Manber looks text in chunks than of every character coalescing the work of Aho-Corasick and Boyer-Moore. Our algorithm reduces character comparisons and consumption of memory on the basis of graph evolution structure and search procedure by means of dynamic linked list. Theoretic study and trial results demonstrates that the projected work is much enhanced in terms of space and time consumption, when compared with previously known pattern-matching algorithms.

Fog Computing-based Internet of Things and its Applications in Healthcare
Authors: Bansal Malti , Sirpal Varun 
Published: May 2021

Abstract
Internet of Things is the most revolutionary and attractive technology of today, which employs a combination of sensors, embedded systems, software and artificial intelligence. These devices are usually coupled with the cloud to produce significant insights. However, the cloud comes with its own issues such as network latency and jitter, which makes it inappropriate for delay-sensitive applications such as healthcare. Hence, a novel paradigm came about known as fog computing, in which computation is carried out at a data collection edge/source. In this paper, we have studied fog computing in a bottom-up fashion, starting from its key features, merits, and then an architecture to show that its integration into a traditional cloud-based IoT system makes it suitable for latency-sensitive applications. We have further made a deep dive into how fog-based IoT systems can be utilized in the field of healthcare, studying the architectures for context-sensitive and at-home healthcare monitoring.
