The objectives of the research were to know the teaching and learning speaking through Fishbowl Technique, to know the teacher's problem in teaching speaking through Fishbowl Technique, and to know the students' problem in learning speaking through Fishbowl Technique. This research was qualitative research. The researcher selected the people or participants who know the phenomenon of the problem. The researcher chose the English teacher and the students of the tenth grade of SMAN 3 Bandar Lampung as the participant of this research. There are two classes which consist of 67 students. The researcher used purposive sampling technique to determine the sample. The researcher chose class X IPA 1 as the sample because class X IPA 1 had the lowest score. The data were gained by doing observation, interviewing the teacher, and giving questionnaire to the students. The researcher used three major phases of the data analysis, they were: data condensation, data display and conclusion drawing verification. After analyzing the data, there were three points of the result. The first, there were some points in teaching speaking through Fishbowl Technique that were skipped by the teacher. It could be seen from process in pre and whilst speaking activity that the teacher did not ask the students' thought and took notes on their activity about their opinion related to the topic, the teacher did not give the students questions for discussion or ask the students to have responses and the teacher did not allow the students to switch their position. The second, the problems faced by the teacher were the teacher had difficulty with the students who did not talk, had difficulty with the students who used their mother tongue, had difficulty with large class size, had difficulty with the material which did not fulfill the students' need, and had difficulty in managing the time. Third, the problems by the students were students were lack in grammar, vocabulary and fluency, had problem to talk or even did not say anything, had problem by using their mother tongue, had problem in confident and pronounced the words, and had problem to follow teacher's direction.

The SEIS will fill up with the temperature and humidity sensor that can measure the condition of the incubator and automatically change to the suitable condition for the egg. The health of egg is very important for the development of embryo within the egg. Improper control means that the temperature or humidity is too high or too low. In this project, the light heater is use to give the suitable temperature to the egg. By using the water and controlling fan, it is can make sure the humidity and ventilation in good condition. The status condition in the SIES will appear on the LCD screen display. To make sure all part of egg was heated by lamp, DC motor is very useful to rotate iron rode at the bottom side and automatically change the position of egg. The entire element will be controlled using programmable integrated circuit (PIC). The PIC is a type of microcontroller that can process a data from sensor and will execute the control element to change the condition of SEIS. This project will be a user friendly product since the SEIS can move to other place. It will secure by user must enter the password before activate the system. vii

Given an image of a crowded environment, the objective is to evaluate the density of the crowd, by counting the quantity of individuals that it contains. There are some approaches to solve crowd reckoning problem. They intend to reckon crowd for a medium sized place. But crowd detection at Hajj Pilgrimage site has never been tried before as far we have studied. Hajj Pilgrimage sites are different than most of the places. The aim of this work is to prevent any future stampede at Hajj Pilgrimage sites. This paper proposes a method where head detection technique is used for the crowd reckoning. It uses the segmentation of head regions from still images. The crowd reckoning will determine the possibility of a stampede and can alarm the people to take necessary steps. Assessment of the proposed model demonstrates worthy performance in realistic operating conditions.

Consequently, employing alloys in the design of wheels results in higher fuel efficiency and lower carbon dioxide emissions. Weight reduction of vehicles also leads to better acceleration. Lightweight automotive design has been increasingly popular in recent years as a means of conserving energy and protecting the environment. The rim is an essential feature of the vehicle since it bears a substantial portion of its overall weight. A vehicle’s weight can be greatly reduced by using a lightweight rim. However, the impact of a lightweight rim on improved fuel economy and reduced carbon dioxide emissions has not been widely explored. In this study, a wheel rim has been designed, and a finite element model has been developed considering radial load, where tire pressure has also been considered. A practical experiment with identical parameters had also been carried out. The values of equivalent stress, strai...

This paper examines the language of trauma studies in two textbooks authored by a prominent trauma analysis expert who has been in the field for more than 20 years. This paper posits that the study or content analysis of trauma narratives discourse textbooks could contribute to self-efficacy beliefs especially in communication management. Using the corpus-based approach, essential keywords, and a word list of the essential language of trauma headwords are identified. Thus, with the 209 identified headwords, the development of the new word list specifically to trauma narratives discourse has been facilitated. The production of the word list of the language of trauma is aimed to assist disaster risk management researchers and authorities in identifying the ‘sensitive’ traumatic keywords to be or not to be narrated to the affected people in community-based studies. Thus, this study entails insightful concepts to the creation of a trauma narrative essential word because of its meaningful application. In conclusion, the article presents the keywords found to be associated closely with trauma narrative textbooks insights and proposes a coping alternative to the community or academia from a linguistics and communication management point of view.

It denotes to the worker's perception of their workplace settings, relationships amid fellows, salary as well as endorsement opportunities. The objective of the study was to determine job satisfaction among physiotherapy professionals working in the private sector. Methodology: A cross-sectional study was conducted in Dhaka, Bangladesh. A total of 103 graduate and postgraduate completed physiotherapy professionals working in the private sectors included in this study. The investigators used a structured questionnaire to collect the data from June to November 2018. Satisfaction level was evaluated by 4-point Likert scale grading and ranging from 1= Strongly dissatisfaction, 2=Dissatisfaction, 3=Satisfaction, and 4=Strongly satisfaction. Results: Results indicated that more than half of the participants were satisfied with their job. Without a salary structure and promotion system, most of the participant's consent on satisfaction about the working environment, leave policy, the security of job place, comfortable with senior, colleague behavior, and cooperation of colleagues. In addition, females were more satisfied than male and young professionals were more satisfied than the senior. However, there was a highly significant relationship found between salary and job satisfaction (p value 0.001). Conclusion: It is concluded from the study that a moderate number of participants in the private sector expressed their job satisfaction. Job satisfaction was influenced by some factors. It is noted that attention on salary structure and review of job might help to increase the level of satisfaction.

Training of network and developing artificial neural network (ANN) models are essential in fault detection in critically large systems. This research focusses on the ANN modelling through training and validation of real data acquired from a sub-critical boiler unit. The artificial neural network (ANN) was used to develop a compatible model and to evaluate the working properties and behaviour of boiler. The training and validation of real data has been applied using the feed-forward with back-propagation (BP). The right combination of number of neurons, number of hidden layers, training algorithms and training functions was run to achieve the best ANN model with lowest error. The ANN was trained and validated using real site data acquired from a coal fired power plant in Malaysia. The results showed that the Neural Network (NN) with one hidden layers performed better than two hidden layer using feed-forward back-propagation network. The outcome from this study give us the best ANN model which eventually allows for early detection of boiler tube leakages, and forecast of a trip before the real shutdown. This will eventually reduce shutdowns in power plants.

The viscoelastic material are modelled as standard linear solids which involve three material parameters. and the motion is treated as one-dimensional. In this study, a viscoelastic slug is placed between two semi-infinite elastic rods and a wave initiated in the first rod is transmitted through the slug into the second rod. The objective is to relate the transmitted signal to the material parameters of the slug. We solve the governing system of partial differential equations using Laplace transform. We invert the Laplace transformed solution numerically to obtain the transmitted signal for several viscosity time constants and ratios of acoustic impedances. In inverting the Laplace transformed equations, we used the complex inversion formula because there is a branch cut and infinitely many poles within the Bromwich contour. Finally, we discuss the relationship between the viscosity time constants, ratios of acoustic impedances and the results of the interface velocity discontinuities.

The viscoelastic materials are modeled as standard linear solid which involve three material parameters and the motion is treated as one-dimensional. We first establish the governing equations pertaining to the impact of viscoelastic materials subject to certain boundary conditions for the case when an elastic slug moving at a speed V impacts a semi-infinite stationary viscoelastic rod. The objective is to predict stresses and velocities at the interface following wave transmissions and reflections in the slug after the impact using viscoelastic discontinuity. If the stress at the interface becomes tensile and the velocity changes its sign, then the slug and the rod part company. If the stress at the interface is compressive after the impact, the slug and the rod remain in contact. In the process of predicting the stress and velocity of wave propagation using viscoelastic discontinuity, the Z-effective which is the effective ratio of acoustic impedance plays important role. It can be shown that effective ratio of acoustic impedance can help us to determine whether the slug and the rod move together or part company after the impact. After modeling the impact and solve the governing system of partial differential equations in the Laplace transform domain. We invert the Laplace transformed solution numerically to obtain the stresses and velocities at the interface for several viscosity time constants and ratios of acoustic impedances. In inverting the Laplace transformed equations, we used the complex inversion formula because there is a branch cut and infinitely many poles within the Bromwich contour. In the discontinuity analysis, we look at the moving discontinuities in stress and velocity using the impulse-momentum relation and kinematical condition of compatibility. Finally, we discussed the relationship of the stresses and velocities using numeric and the predictable stresses and velocities using viscoelastic discontinuity analysis.
