Suspension is one of the important components of automobile products, and the smooth operation of the automobiles is closely related to the structure of the suspension. This paper studies the semi-active suspension control and its performance test by firstly introducing the suspension, then analyzing the neural network control basis and designing the single-chip control system, and finally formulating the performance evaluation criteria of suspension to evaluate its function. The performance of the semi-active suspension built on the basis of neural network control theory is better than that of the passive suspension and active suspension, so it can be promoted in the future application.

Underactuated overhead cranes play an important role in engineering and construction, which also make nonlinear control strategies and planning on this basis become the current focus of academic research. Based on scholarly research findings, this paper carries out a theoretical study on nonlinear control strategies and planning for underactuated overhead cranes. To begin with, the underactuated system, underactuated overhead cranes and its nonlinear control are elucidated. Afterwards, the stabilization methods for front actuators are analyzed, and finally two nonlinear control methods are explored in the hope of providing some references for research in related fields.

Sustainability Education (SE), Education for Sustainable Development (ESD) and Education for Sustainability (ES) are the terms commonly used to describe the practice of teaching for sustainability. SE requires participatory teaching and learning methods that motivate and empower students to change their behaviour and play role in embracing concept of sustainable development. SE promotes competencies like critical thinking, imagining future scenarios and making decisions in a collaborative way. These competencies can also be applied for sustainable research since education and research are interrelated. To develop SE, it may be relevant to address the sustainable development in the curriculum or syllabus. The three pillars of sustainable development; environmental, economic and social might be used and adapted in academic and research disciplines. There is no specific pedagogy for SE, but there are several elements that can be adapted in the teaching environment such as critical reflection, systemic thinking and analysis, participatory learning, thinking creatively for future scenarios and collaborative learning. For instance, transdisciplinary research in assessing environmental performance of pollutants can be practised by extending the research including the impact pathway of the pollutants on economic growth, society well-being (human health) and awareness level of community. Transdisciplinary research not only look at one specific discipline, rather than look at the issue from a holistic perspective by establishing the linkage between environmental aspect with social and economic aspects. Transdisciplinary research also requires triple helix effort by strengthening government-academia-community relationship. This will help to inculcate different stakeholders with a sense of duty towards safeguarding human health and environmental stewardship. Thus, the SE can be established through transdisciplinary research which integrate and move beyond discipline-specific approaches to address a common problem.

Ficus (Moraceae) is a tree or shrub natively originated from East Asia countries such as Middle East and Turkey. However, determination of the most suitable cultivation method in Malaysia has becoming one of the major concerns in figs industry. This is because figs can be easily found in cold and temperate regions compared to the equator regions. Therefore, this paper will discuss on the method of figs cultivation and its production based on the market demands in Malaysia. Simple propagation methods such as cutting, and layering are the most recommended method used for cultivating the fig trees. As for the production, figs are mainly processed as food such as jam, tea, dipping sauce, spaghetti sauce and dried processed food or available fresh. It is also used in traditional medicine as it is claimed to be good remedies in treating severe health problem such reducing blood sugar level and gastrointestinal problem.

This paper presents experiments and computer simulation for the erosion and deposition processes along a 180° open canal bend. The computer simulation is conducted by Nays2DH model in iRIC software. The models are conducted with the curvature’s radius ratio (Ø/L) varies within 3.0 to 8.5. Experiments produced that the erosion and deposition actions decrease as Ø/L increases. The minimal erosion and deposition are detected at (Ø/L =8.5). The optimum place of a bridge circular support along the bend is defined. The results of Nays2DH Model are compared with tests. RSQ for the modelled statuses is 88.329% and the correlation factor between simulations and the gauged depths is 93.98%. 20

Food delivery system is very popular nowadays. This system is very useful specifically for women that go through their confinement alone. Food for women in confinement is very important to their health. Not only for the women, but also for their babies. Women could choose the package they like thus reducing the hassle to prepare the confinement menu. In this paper, we present the information technology in health especially in confinement. With this system, the woman could focus on her baby and health without the stress to prepare food.

As a widely applied method in many fields, parametric design is now finally exerting influences on architectural industry with the rapid development of Internet technology. For this reason, parametric architectural design is studied in this research based on optimization method. First, parametric design and optimization algorithm are introduced; then, the process of modeling and optimization procedures is discussed; at last, the parametric optimization design is applied to solve the complex architectural design problems. Parametric method will thoroughly affect architectural industry. Therefore, architectural designs should be based on optimization algorithm using parametric design to improve the progress and quality of architectural design.

A solution for reducing the amount of generated electronic waste in India has become one of a major issue. Globally this problem has taken major part of total solid waste amount. Rectifying this waste is still questionable because we cannot burn it easily, landfill is also harmful for this waste and dumping into sea with affect aquatic life. So it is a matter of finding a best solution for it so that we can use this waste in different work. This research is about reducing the generated E-waste from environment by adding it into M25 Concrete and hence testing for workability and compressive strength. This study helps in optimizing the generated amount of E-waste and its scope in construction industry. This experimental research adds 0, 4, 8, 12, 16, and 20 % of E-waste by weight in M25 concrete and hence tests it for workability and compressive strength.

The rice husk is an agricultural waste which is obtained from milling process of paddy and approximately 22% of the weight of paddy is rice husk. The waste is used as fuel in producing stream in parboiling process. The 25 % the weight of husk is converted into ash which is known as rice husk ash (RHA) and is again a waste which is disposed. This ash consists of amorphous silica which can be used as pozzolana in making concrete and cement instead of disposing it without compromising on the properties of cement or concrete if replaced in specific proportion with other constituents of cement or concrete. In this study the ordinary Portland cement is replaced in different proportion with RHA to obtain concrete with comparable and satisfactory strength and properties to that of normal concrete. The proportions of replacement chosen are at 2.5% interval starting from 5 % to 15 % and the casted concrete were tested under compression at different ages and results obtained are compared with normal concrete of same grade and it is co ncluded that the results are comparable.
