Time domain analysis of electroencephalogram (EEG) signals for word level comprehension in deaf graduates with congenital and acquired hearing loss
Authors: Shirly G , Jerritta S 
Published: February 2021

Abstract
Deafness can be classified on the basis of onset as congenital and acquired hearing loss. The brain is a sensitive part of our body, electrical pulses from the neurons interact with each other, generating brain signals. EEG signals are extensively used for clinical diagnosis for any brain anomalies, language comprehension and performance measurement studies. This study mainly focuses on analysing the word level comprehension in deaf adults in the age group (21 -25 years) using EEG signals. The raw EEG signals were pre-processed and the relevant time domain linear and nonlinear features were extracted and classified using machine learning algorithms. The approximate entropy feature was found to be best suited for finding the comprehension of both congenital and acquired deaf adults. This feature of ISL was observed to be achieving better classification rate with a maximum average accuracy of 96% in both congenital and acquired deaf adults using SVM classifier.

Authors: Pannickottu Nivya Kuzhivila , Deepa K 
Published: February 2021

Abstract
The usage of Lithium ion (Li-ion) batteries has been increasing day by day due to environmental concerns. One of the major applications in which Li-ion batteries are used is electric vehicles (EVs). Li-ion batteries are highly sensitive to over-voltage, under-voltage and temperature conditions unlike other batteries. Li-ion batteries need real-time monitoring and a battery management system (BMS) is used for this purpose. This paper talks about active cell balancing schemes using transformer switching. Active cell balancing is done to balance the imbalances created in the battery pack to maintain a constant state of charge (SOC). A comparative study on pack-to- cell configurations of active cell balancing using switched transformer method is done to draw conclusions.
Harris hawks optimization algorithm based power loss minimization in micro grid incorporated with distributed generation
Authors: Kasi Santhosh , Neela R 
Published: February 2021

Abstract
In this paper, Harris hawks optimization algorithm is used to solve the distributed generation placement problem in the micro grid. Distributed generation will effectively mitigate the loss of a real power system and improve the voltage profile. Thus, reducing actual power loss is viewed as a fitness function to optimally locate and rate the distributed generation in the micro grid. The method presented is applied in the IEEE test systems, such as the 33-bus and 69-bus micro grids. Simulation analyses are performed in MATLAB simulation software and simulation results are compared with existing PSO and ES-PSO algorithms. The results show the superiority and consistency of the Harris hawks optimization algorithm in terms of power loss minimization, voltage profile, and execution time.

Authors: Lokanadham D , Venkata Subbaiah K 
Published: February 2021

Abstract
An attempt is made on tribological performance of aluminium composite (Al-Mg-Si) reinforced with Limestone slurry waste powder (LSP). Aluminium Metal matrix composite (AMC) is prepared using LSP by varying from 4% wt to 16% wt. LSP with 12 %wt. is shown better wear performance as compared to others. The experiments are designed based on the Taguchi approach (L25). In this study, sliding velocity (V), % of LSP (R), sliding distance (D) and load (L) as input parameters, whereas wear rate (WR- mm3/Nm) and coefficient of friction (CF) are responses. In addition, multi-variables are transformed to a single grey relation analysis (GRA) variable. The multivariable wear behaviour responses are transformed into one single variable with a grey relation grade. Analysis of variance (ANOVA) has been performed to determine the contribution of each parameter with interaction effects of design variables. The experimental results specify that the performance of wear behaviour characteristics in the tribological process has been improved by using grey-fuzzy reasoning grade (GFRG).

Abstract
Microforming is a method of manufacturing near-net shape micro parts by plastic deformation. This method has attracted much attention and is potentially adopted to manufacture various micro parts due to its distinct advantages, such as good strength of the deformed parts, high production rate, less scraps, and low cost. Among the materials studied in microforming research, copper is the most studied material, followed by aluminum and steel. Recently, magnesium has become an interesting research topic since the trend of magnesium application has emerged in electronics and medical fields. However, magnesium has low formability at room temperature that makes magnesium microforming a challenge. Hence, this paper discusses an overview about recent development in magnesium microforming and the challenges in controlling the size effect and formability of magnesium by elevated temperature and grain refinement.

Published: February 2021

Abstract
In recent years, vegetable oil based bio-lubricant has drawn attention due to its inherent eco-friendly characteristics such as non-toxicity and high biodegradability. Low thermal-oxidation stability and pour point temperatures limit large-scale industrial application of vegetable oil based lubricant. The present work studied improvement of pour point temperature and oxidation stability of Camellia sinensis assamica (tea) seed oil (CSO) with varying weight percentage of Camellia sinensis assamica deoiled cake derived bio-oil. Bio-oil was added with CSO at 5%, 10% and 15% concentration by weight. The results showed improvement of oxidation stability due to presence of alkylated phenols in bio-oil. The oxidation onset temperature was increased from 243.89°C to 274.55°C. The pour point of CSO also improved from initial temperature -4°C to -27°C.

Published: February 2021

Abstract
As a disaster-prone area, the city of Banda Aceh was one of the locations that experienced an earthquake and tsunami that destroyed parts of the city at the end of 2004. An earthquake with a magnitude of 9.3 SR accompanied by a tsunami resulted in almost half of the settlement area of Banda Aceh being severely damaged. After destroyed by the biggest earthquake in Indonesia in the past few decades, the city of Banda Aceh has now recovered and is preparing itself as a city that is alert to disasters. The city recovery process has proceeded relatively quickly, and this has influenced the enthusiasm of citizens to be involved in working with various domestic and foreign institutions that helped build Aceh post-disaster. One of the countries that have collaborated with the Banda Aceh city government in disaster preparedness is the Japanese government. The collaboration was manifested in the form of sharing experiences, training, and discussions on disaster mitigation in the construction of the city of Banda Aceh as a sustainable city that is disaster prepared. With the openness of the city government to accept input and support from outside, many disaster preparedness-based activities are carried out to educate the public to be alert for disasters. For this reason, the study seeks to evaluate the disaster preparedness of the city of Banda Aceh, especially the coastal settlements of the city of Banda Aceh that are prone to the tsunami disaster. This aspect of the review in disaster preparedness-based research includes post-disaster plans to develop coastal urban settlements and rescue routes. The study began with a discussion of the initial mitigation plan a year after the 2004 disaster, followed by the conformity of the implementation of mitigation plans for several earthquakes that occurred in Banda Aceh between 2005 and 2018. In comparison, disasters and mitigation plans in Japan were also discussed. The results of this study are expected to be a reference for a better urban disaster mitigation planning not only for Banda Aceh but also can be used in other cities in Indonesia.

Abstract
In this paper, an experimental study was carried out to evaluate the number of layer effect of abaca fiber composite as natural reinforced polymer (NFRP) material for shear-strengthened reinforced concrete (RC) beams. Two externally bonded shear-strengthened beams with a different number of NFRP layers and a sound beam as a control beam were prepared. The test was conducted by applying two axial loads on the beam. The results showed that the use of one-layer and two-layer of abaca fiber composite as NFRP material for the shear-strengthened beam increased 9.78% and 9.92% of maximum load compared to sound beam respectively. Abaca fiber composite NFRP material contributed 11% and 18.57% of the total maximum shear load for one-layer and two-layer laminates respectively. In addition, externally bonded shear-strengthened beams affected the crack pattern and deflection value. However, debonding failure of NFRP laminates occurred in two-layer of the NFRP shear strengthened beam. It caused the beam did not work optimally.

Abstract
Understanding the sun-path in designing an energy-saving building is essential. Saving energy is approached by daylight provision, which needs access for lighting the room during the day. In some latitudes, the building also needs the thermal mass to warm up the building during the cold time, requiring the sun’s heat radiation. The sun path on the regions creates various ways to design buildings. There is multiple architecture software embedding the sun-path feature. However, the software is not easily installed for free, and some other constraints become the challenges for students to learn it. Therefore, this article figures out the project-based learning in utilizing sun path in 3D models for architecture students. The methods comprise the small project designing sun path in 3D models in various latitudes supported by Andrew sun-path software. This study aims to understand the position of the sun throughout the year, which in building design is useful for saving energy in ventilation and lighting applies. The result is the students’ knowledge achievement for understanding the sun position and the site and building analysis toward the sun for obtaining the saving energy building design.
