Abstract:

The advancement and frequent usage of smartphones have penetrated everyday life to a point that mobile apps become one of the essential tools of conduct. Even now, the application of mobile app has shown its significance in the mHealth fields to help overcome many health-related problems. Hitherto, one of the global health issues that are terrorizing the public health is the emergence of antibiotic resistance. Yet, the public awareness on this matter is significantly low, suggesting that the awareness programs were slow to show their effectiveness. Thus, this study highlighted the need to develop an awareness mobile app, known as SEDAR, which is short for ‘Stop and End the Drastic Antibiotic Resistance’. In addition, the aim of this paper is to convey and describe the development of the SEDAR awareness app and convey the results of the preliminary testing of the app. SEDAR app was developed on the Android platform and consisted of two parts; the quest and the feedback. The quest evaluated the users’ responses on antibiotic-based situations and portrayed the feedback in the form of scores. Based on the preliminary testing of the SEDAR app, more than 60% of participants showed likeability to repeat the quest and 90% out of the participants who repeated the quest improved their scores. This inevitably demonstrated that the SEDAR app showed potential in encouraging the public to learn and understand more about antibiotic resistance issues, to which the conventional awareness programs had limitations.

Abstract:

This paper examines the recovery of carbon fibers (CF) from a polymeric composite waste of high end application industry. Thermolysis technique and gasification in nitrogen coupled with oxygen atmosphere is applied by particularly studied the influence of different process parameters (final heating temperature, atmosphere and heating rate). Thermal decomposition analysis of the high end application CFRP waste cured carbon fibre was studied by thermogravimetric analysis (TGA). The samples were heated in dual environment of nitrogen (420⁰C) and oxygen (540⁰C) at different heating rate (5 and 10⁰C/min). Visual inspection was performed with SEM and FT-IR, respectively to assess the morphological properties and chemical composition of the recovered CF. Molecules of epoxy resin components were found to decompose in nitrogen atmosphere followed by complete matrix decomposition in oxygen atmosphere. Lower heating rate at 5⁰C/min efficiently separate the left reclaimed carbon fibre from their matrix. The different system of CFRP from industrial waste required different recovering methods of CF

https://doi.org/10.26782/jmcms.spl.9/2020.05.00003

Abstract:

In the available microprocessors and microcontrollers, the multi-bit operations are implemented with very less efficiency. Generally, these complex bit operations are emulated using programming logic. These bit manipulation operations are frequently required in the applications that are becoming very important. In this paper, we propose two new techniques which can directly support these bit operations in the form of shifter unit that can implement standard shifter operations in microprocessors and controllers. The design of the proposed shifter unit is based on the inverse butterfly circuit.[X] In this paper, we propose two techniques that have shift/rotate and mask circuits which enable the same circuit to perform all types of the standard shift and rotate operations found in some processors. The first technique is using Data reversal method and second using Two’s complement method. The design of Shifter-Permute functional unit is the important and critical task towars optimizing parameters such as speed, area and power consumption. Here we have implemented an 8-bit Shift-rotate functional unit for bit manipulation in the form of two approaches and have analyzed the circuits in terms of speed, area, and power consumption. Here the circuits are implemented and analyzed by using the most popular semi-custom design tool Vivado ISE 2015 and is synthesized by using Artix-7 FPGA and the same is reflected in the mathematical model purposed for each circuit.

Abstract:

The contribution made by authors in the research work carried out on square operation is bought forward operated on a four and eight-bit number using duplex property of number based on Vedic mathematics. The conventional method of computing square of a number follows the polynomial multiplication of the same number to find the square. The said method requires the area and power consumption is not sufficiently optimized considering today’s low power application needs. The proposed method of computing the square of a number presented here is based on the Dwandva yog of Vedic mathematics which also called as duplex property of a number. The duplex method of calculating the square of number gives the online solution which can be easily calculated mentally and the efforts were to prove the same with the electronic circuit. The implementation of the square algorithm using polynomial multiplication and Vedic mathematics based duplex property for square operation is carried out with VHDL coding on the Xilinx Vivado 2015 ISE tool and the FPGA used is Artix7 device: 7a35tcpg236-1. The results were compared with 4-bit as well as 8-bit operation using both algorithms for a square operation are it is observed that the speed of operation is improved by 20 % whereas the hardware resources utilized were reduced by 66 %.

EFFECT OF CU ON THERMOELECTRIC PROPERTIES AND ELECTRONIC BAND STRUCTURE OF INKJET PRINTED ZNXFE2O4 THIN FILMS

Authors:

Lim Joon Hoong,

DOI:

https://doi.org/10.26782/jmcms.spl.9/2020.05.00005

Abstract:

In this paper, Zn_xCu_(1-x)Fe₂O₄thin films were deposited by using inkjet printing and Zn_xCu_(1-x)Fe₂O₄bulk pellets were synthesized through solid state method. Multiple print cycles were required to deposit homogeneous Zn_xCu_(1-x)Fe₂O₄ thin films. The obtained samples were characterized by X-ray diffraction (XRD), electrical conductivity, Seebeck coefficient and thermal conductivity. The XRD results confirmed the formation of cubic spinel structure of Zn_xCu_(1-x)Fe₂O₄thin films and pellets. The electrical conductivity of Zn_xCu_(1-x)Fe₂O₄ (x=0.0) thin films sintered at 400 ºC (1.185x10^-3 S/cm) had the higher values. The electrical conductivity of Zn_xCu_(1-x)Fe₂O₄ thin films was about 11% higher compared to Zn_xCu_(1-x)Fe₂O₄ pellets. The electronic band structure shows Zn_xCu_1-xFe₂O₄ is an indirect band gap material. The Fermi level of Zn_xCu_1-xFe₂O₄ was shift downward to the valence conduction band. It indicated Zn_xCu_1-xFe₂O₄ is a p-type semiconductor. Seebeck coefficient of Zn_xCu_(1-x)Fe₂O₄ thin films and pellets remained positive, confirming charge transport by hole carries. The presence of Zn served to decrease thermal conductivity of Zn_xCu_(1-x)Fe₂O₄ by 8 W/mK as Zn content increased from 0 to 1. The similarity observed in the change of properties might indicate that similar mechanisms are dominant in both the Zn_xCu_(1-x)Fe₂O₄ bulk pellets and the thin films.

Abstract:

The tourist information recommendation system is useful for both tourist’s them-selves and tourist operators. This recommendation system can support tourists to spend less time searching for tourist attraction information and also be a channel for public relation to create incentives for tourists to use the services. User profiles is an important part of recommendation system that is responsible for finding the users’ interest and is a good representative for each tourist. However, creating a user profile to suitable each user in the tourist information recommendation system is still considered as challenging due to insufficient data collection. In addition, the use of social networks at present is becoming increasingly popular and is a source of information that has many users which can be extracted to represent the interests of each user. Therefore, this research has studied the recommendations for creating a user profile for the tourism information recommendation system in Thailand by using ATRU model to create User Profiling.

Abstract:

This study is devoted to one of the most common types of wooden structural elements joints - nailed connections. The article presents the results of experimental studies of two types nailed connections on metal plates: traditional connections without bushings and connections, reinforced (modified) with pressed-in fiberglass bushings. The methods of mathematical planning of the experiment were used during the test. That allowed to significantly reduce the number of tested samples of connections and to obtain mathematical dependences in the form of response functions for such characteristics as breaking load N_t and load N_I-II, corresponding to the upper boundary of the elastic behavior area of the compound from three factors: the angle between the direction of the acting force and the direction of the wood fibers, the dowel diameter and the wall thickness of the fiberglass bushing. The obtained dependences allow us to evaluate the values of the loads N_t and N_I-II for the nailed connections with bushings without testing.According to the experiment planning matrix, 15 types (series) of connections with pressed-in fiberglass bushings and 9 types (series) of traditional nailed connections without bushings were tested.According to the test results, the authors made a comparison of the load bearing capacity and deformability of two types of nailed connections, with bushings and without bushings; the nature of the damage has been established; the analysis of stress-strain state of the middle wooden element in the area of mortise strengthened with pressed-in fiberglass bushing is performed; the conclusion about prospects of application of a pressed-in fiberglass bushings to enhance mortises of new structures and when reconstructing wooden structures in operation.
