Abstract

Nowadays medical imaging systems tend to have the greatest impact on disease identification, diagnosis, and surgical preparation. At the same time, compression of image avoids data redundancy, reduces bandwidth, etc. This makes the system more peculiar in this field. Three main steps are being used in the proposed paradigm: (a) segmentation, (b) image compression, and (c) image decompression. Image segmentation is the first step, which is attained by the Optimized Active Contour Model (OACM). Using a new Modified marriage in honey bees optimization model (MMBO), the weighting factor and maximum iteration of ACM are fine-tuned. Thereby, the collected input image is differentiated or segmented into two: N-ROI and ROI, respectively. The ROI marked field will indeed be encoded using ISPIHT based lossy compression model, whereas the non-ROI area is encoded using DCT based lossy compression model. In terms of BSC, the outcomes from both the ISPIHT algorithm and the DCT model are merged and the compressed image is its output. Following that, the compressed image will then be subjected to image decompression. This will include bit-stream segregation, which will be processed separately for the ROI and non-ROI regions using both ISPIHT decoder and DCT based decomposition. This process results in the original image. Finally, a comparative evaluation is undergone between the proposed and the existing techniques in terms of PSNR, SSIM, and CR as well.

Abstract

The Anthropological Theory of Didactics has been applied to the field of didactics of mathematics with remarkable success. Fluid Mechanics is a discipline with a strong mathematical background, where mathematics is used for modeling the continuous environment. In addition, the Fluid Mechanics concepts are essential for the future engineer or scientist. For this reason, it is worth thinking whether the content that developed in engineering schools or science faculties are those demanded by the future professionals. The objective of this article is to know the institutional distance between the University and society as a demander of technologies based on Fluid Mechanics. To this end, the methodology based on the issuance of a questionnaire to experts focused on aspects such as present and emerging content associated with the Fluid Mechanics of an engineering degree is used. The results highlight the existence of an institutional distance between the University and the Enterprise (as a technology executor) in the conception of contents, thus establishing an area of potential improvement within the noosphere associated with fluid mechanics.

Abstract

The objective of this paper presents the numerical demonstration of the pneumatic valve unit with the Model reference versatile regulator in drink fabricating organizations for the container washing process. Earlier to utilizing the holders after it is gotten back from the clients' side, it ought to be cleaned within the container washer sometime recently they can be reused. The release of clean jugs constrained by the pneumatic valve of the container clothes washer once in a while sticks or bombs which brings about huge loss of creation in the plant, since the wide range of various cycles which follow rely upon the jug clothes washer. The primary target of this examination is to decide the fundamental driver of the staying and coming up short of the pneumatic valve clothes washer and to give reasonable versatile control arrangements that abatement smashing circuits. Feathery Rationale Controller has way better clamor expulsion and is heartier to the changing plant boundaries when differentiated with PID controllers and no complex numerical show is required for the system controller setup differentiated with the standard control procedure. Nonetheless, the Fuzzy Logic Controller can't adjust to the changing nature and working conditions, so it is important to utilize some type of transformation to accomplish the ideal prerequisites of the framework to changing ecological and working conditions. In this review, MRAC will be adjusted to give the transformation needed to accomplish the wanted framework execution. Thus, this paper will introduce a relative investigation of MRAFC and F-PID regulator setup for the pneumatic valve of jug washers in the Beverage Company. At last, the created framework will be tried for a long time runs utilizing MATLAB/Simulink tool compartment and the viability and legitimacy of the proposed control approach will be checked by reenactment results dependent on different control framework boundaries, for example, rise time, settling time, and pinnacle overshoot.

Abstract

In the wireless channel environment, the data transmission faces many safety problems and power transmission loss. This results with the negative impacts while precise channel estimation. Furthermore, the existing channel estimation (CE) model directly estimates the channel matrix; still, the accuracy and the high complexity may cause path loss. Alternate to the direct estimation in the channel matrix, the parameter estimation model is used to solve the above issues. Moreover, the training based CE including Linear Minimum Mean Square Error (LMMSE) and Least Square Error (LSE) are ubiquitous in certain wireless standards to reduce the Mean Square Error (MSE) among the estimated and original channel. Certain intelligent optimized techniques are introduced to optimize the channel. This paper intends to introduce a Trellis Coded Modulation (TCM) with hybrid optimization in LMMSE for the Optimal CE. Moth amalgamated Elephant Herding Optimization (MAEHO) algorithm is the proposed hybrid optimization. At last, the performance of the adopted model is computed over other existing schemes in terms of various measures.

Abstract

Affective states in learning have gained immense attention in education. The precise affective states prediction can increase the learning gain by adapting targeted interventions which are able to adjust the changes in individual affective states of students. Several techniques are devised for predicting the affective states considering audio, video and bio sensors, but the system that relied on analyzing audio, video cannot certify anonymity and are subjected to privacy problems. This paper devises a novel strategy, namely Rider Squirrel Search Algorithm-based Deep Long Short Term Memory (RiderSSA-based Deep LSTM) for affective state prediction. The training of Deep LSTM is done using proposed RiderSSA. Here, the RiderSSA-based Deep LSTM effectively predicts the affective states like confusion, engagement, frustration, Anger, Happiness, disgust, boredom, surprise, and so on. In addition, the learning styles are predicted based on the extracted features using Rider Neural Network (RideNN) by which the Felder Silverman Learning Style Model (FSLSM) is considered. Here, the RideNN classifies the learners. Finally, the course ID, student ID, affective state, learning style, and the exam score are taken as output data to determine the correlative study. The proposed RiderSSA-based Deep LSTM provided superior performance in contrast to other techniques with highest accuracy of 0.962 and highest correlation of 0.406 respectively.

Abstract

In this paper, an observer based robust state feedback control strategy is proposed for a car suspension system with nonlinear actuator in order to moderate vertical motion of the body. At first, an adaptive inverse control is developed to overcome the nonlinearity of the actuator. Secondly, to cope with unavailability of some states of the system, a velocity observer is employed. Afterward, an observer based robust state feedback control is suggested for the system and robust stability of the overall control system is proved by Lyapunov theory. Efficiency and robustness of the proposed method is shown by comparing simulation results for the active and passive suspension system in the same road conditions.

Abstract

Cleaner production is an environmental management effort through preventive strategies to prevent pollution and waste of materials before the pollution occurs which is carried out in a sustainable manner in the hope of reducing the negative impact of the activities carried out. The view in cleaner production itself will provide a different perspective to achieve and sustainable consumption with the value of the resources that have been used. However, so far the batik production process is still considered inefficient and environmentally friendly. Thus, this study aims to determine the process of making batik and the behavior of efficiency in the batik production process in Afina Batik’s MSME. This research was conducted by observation and interviews. Interviews were conducted using purposive sampling method. Then, given solutions related to the management of Afina Batik to go to cleaner production. The interviewees included the flow of the batik production process, the raw materials used, the use of energy in batik production, both water and electricity, the use of chemicals, the type of waste generated and the amount, and the waste treatment process. The results obtained are various wastes from the dyeing process to washing. In addition, several factors were found that hinder Afina Batik from moving towards a cleaner production process, such as the use of synthetic dyes, still using cordwood, and still wasteful use of air. There are several methods that can be used to implement cleaner production at Afina Batik’ MSME, namely by maximizing the use of candles to efficient use of energy, air, and raw materials.

Abstract

Given the popularity gained by ICT in universal education in the past two decades, as new capabilities for technology integration emerged, its use in educational contexts has steadily increased. The use of technology for a broad range of teaching and learning purposes is now established at many universities. Studies were conducted about technology use attitude in education, but the majority has concentrated on how to replace traditional with blended methods of instructions. This study examines Science Technology Engineering and Mathematics (STEM) teachers’ attitude towards technology use in teaching in Bangladesh. A descriptive research design was used.  Research instrument employed was questionnaire which was administered on 120 STEM teachers from three sampled universities of Bangladesh. It was found that the respondents’ affective, perceived usefulness, behavioural intentions, and overall attitude towards technology use were significant, though challenges that include domain (affective, cognitive, perceived control), conceptualization of technology use attitude, teacher-training, objectives and contents were obtained. In essence, the study findings revealed a positive attitude of the STEM teachers towards technology use in teaching in Bangladesh universities and challenges needed to be overcome for better teacher delivery. A technology acceptance model formulated by Venkatesh and others (UTAUT) which hypothesized on user acceptance of technology towards a unified view was used in this study. The theory wants to explain user intentions to use technology following behavioral intensions. The constructs of UTAUT (performance expectancy PE, effort expectancy EE, social influence SI and the facilitating condition FC) are found to have positive effect on behavoiural intension and the attitude of technology use in teaching as well. Attitude is the most important detector of behavioural intension towards the use of technology by STEM teachers (Troy et. al 2013).
