Background: Optimization of reinforced concrete foundation is a challenging problem due to the interaction between the design variables and design constraints. Classical design methods may overestimate the size of the foundation, thus leading to excessive cost. By using current advances in computer technologies and numerical optimization procedures, it is possible to find the optimum combinations of foundatio Read More

Background: Capacitive Micromachined Ultrasonic Transducer (CMUT) is a new type of ultrasound transducer that has gained much research interest in ultrasound imaging because of its wider bandwidth, higher receiving sensitivity, and is more likely to be integrated with an integrated circuit (IC). The analytical solution is intuitive, fast, and convergent among simulation methods. The membrane deflection is important t Read More

Contour crafting application has been widely used in different industrial, pharmaceutical, medical, and aviation applications for more than three decades. Recently, mega-sized 3-D printers were developed, with sufficient capability to print full-scale construction projects, including walls, homes, bridges, and multi-story buildings. Successful 3-D printing of projects is accomplished by the Additive Manufacturing (AM) proces Read More

Background: Rolling mill vibration has become one of the most widespread and unsolved problems in the rolling industry, which is called "Ghost" vibration. The research on the starting mechanism, vibration characteristics and vibration suppression measures of high-speed tandem rolling mill has always been a hotspot and difficult point in the field of rolling at home and abroad. However, up to now, the research on rolling mill Read More

With the progression of technology, models of linear multistate consecutively-connected systems (LMCCSs) have been applied more widely, such as in telecommunication systems and the Internet of Things, among other applications. LMCCSs contain a series of linearly arranged nodes, and any disconnection between nodes will lead to the failure of the entire system. Thus, the reliability of a linear multistate system is affected by Read More

Background: Nitrosamine is a chemical, commonly used as a preservative in red meat whose intake can cause serious carcinogenic effects on human health. The identification of such malignant chemicals in foodstuffs is an ordeal. Objective: The objective of the proposed research work presents a meta-heuristic approach for nitrosamine detection in red meat using a computer vision-based non-destructive method. Meth Read More

Background: Greenhouse cooling is very essential during warm conditions to extend the cropping season and offer year-round production. Although fan-pad systems are widely utilized for greenhouse cooling in arid climates, they have many drawbacks mentioned by researchers. Thus, finding the best cooling system had attracted the attention of many researchers and inventors in such climates. Objective: This paper aims to r Read More

Embedded multi-core systems often show special limitations in sharing resources and storage capacity, which will lead to the reduction of parallel efficiency due to bandwidth, data competition and other factors. In this paper, a run-time optimization framework is proposed to dynamically and adaptively adjust parallel strategies according to the structure of different parallel programs. On the one hand, the performance analysi Read More

Background: At present, there are a few research studies on the stability of the supporting structure of bored piles with steel supports for deep foundation pits, and it is even less common to use this support method for deep foundation pits in sandy pebble stratum. This paper studied the stability of the deep foundation pit support of the Southwest Jiaotong University Station in Chengdu, China, using the stability analysis the Read More

Aims and Objectives: Mobile Ad hoc Networks (MANET) hold a set of numerous mobile computing devices useful for communication with one another with no centralized control. Due to the inherent features of MANET such as dynamic topology, constrained on bandwidth, energy and computing resources, there is a need to design the routing protocols efficiently. Flooding is a directive for managing traffic since it make Read More

Background: Most non-developing and under developing countries strive hard to tackle the situation of power crisis and to combat the imbalance between the power generation and load demand, especially in the case of increasing of the population. In this situation, the load shedding scheme has been extremely implemented as a fast solution for unbalance conditions. Thus, load shedding is crucial to investigate supply-deman Read More

Background: The perineum area that interacts with the saddle is vulnerable; compressing neurovascular tissues has been asserted as the link to pathologies. Existing saddle designs are mainly based on the hole blocks, which are composed of two materials. These composite combined structures increase manufacturing difficulty. Objective: The injection molding technology is suitable for mass production. We proposed a Read More
