Abstract: According to the U.S. National Highway Traffic Safety Administration, single vehicle road departures result in many serious accidents each year. An intelligent lane markers recognition and localization system can assist vehicles stay in proper location of a lane that will reduce possibility of car accidents correspondingly. A great deal of lane recognition algorithms have been developed over the past several decades. However, reliable detection is still an issue because of variable road face conditions. An optimum algorithm, Probabilistic Hough Transform (PHT) is presented in this paper for intelligent Lane markers recognition which use a fixed camera installed on the vehicle to transmit video information. The result of experiment proved that under inconsistent illumination and a diversity of road conditions, the accuracy and efficiency of developed system have been improved greatly.
Abstract: In computer science, the dining philosopher’s problem is an illustrative example of a common computing problem in concurrency. It is a classic multi-process synchronization problem. In this paper, we proposed a mathematical model which it expresses an adjacency matrix to show the deadlock occurs, and how resolve it.
Abstract: Product design is a complicated thinking activity of creation of human. Based on analyzing product design and its process, using a theory and method of aggregating and mapping, models of product design, process of product design, process of conceptual design of product were constructed, a frame of network arithmetic of a process of conceptual design of product was presented, its flow of decomposition and integration was particularly defined, a good base for modeling and ruling of process of product design was founded. At the same time, a useful exploration of development of a computer support implement for process of product design at all life cycle was made.
Abstract: In low-end equipment developing it is often have the requirement of use low-cost pressure sensors, but the maketing pressure sensors’s price is very higher than the SCM. For decrease the price of the equipment to suit the market we explored a low-cost pressure sensor disgn. It is based on the bourden tube pressure gauge, SCM control system, Gray code disc and photoelectronic reading technology. The design can suit the certain low-cost equipment.
Abstract: This article, on the basis of the magnetically levitated pumps developed by Ibaraki University, talks about fluid dynamic analysis of pump and optimization of parameters of the impellers. The pump uses blood as medium, with a flow rate Q of 5L/min, a pressure head H of 100mmHg. By using software of ANSYS CFX, the article analyzes the effect of shape, angle, height, length and thickness of the impeller on performance chart and fluid field distribution inside the pump. To fulfill the human requirements in blood pump, an optimization analysis is conducted to improve the uniformity of fluid field, reduce power and efficiency of the pump. As result, meeting the flow and pressure head condition, single curvature impeller is found to have lower speed, better efficiency and more uniform flow field, this helps to prevent the generation of thrombus and hemolytic.
Abstract: The production rate and pellicle thickness of bacterial cellulose (BC) from Gluconacetobacter xylinus ATCC 23768 could be improved by Taguchi method. The initial pH is the important factor of medium to affect the BC production. After the confirmed experiment, the optimum modified YPD medium is: initial pH=4.5, glucose concentration = 2% (w/v), acetic acid concentration= 1.5% (v/v), medium volume = 430 mL and vessel basal area = 246 cm2. By the modified factors and levels, the maximum wet BC production rate and wet film thickness could be increased 53.1% to 111.90 g-BC/L and 43.3% to 4.43 mm, respectively. Higher basal area could get higher pellicle production rate.
Abstract: Orthodontic is one of the treatments in dentistry field which concerned on malocclusion treatments such as improper bites, tooth irregularity and disproportionate jaw relationships. The mini-implant (OMI) is one of the components used in the orthodontic treatment, besides braces and spring. The application of OMI has been well accepted in orthodontic treatment. However, one of the main factors of OMI failures is the implant insertion procedure in which the clinician find it difficult to obtain the best angle to insert the OMI. Therefore, this study aims to evaluate stress in an OMI and bones using the finite element analysis (FEA) with variations of insertion angles and to identify their optimal angle for the implant placement. The three dimensional (3D) model of a left maxillary posterior bone section was constructed based on CT image dataset. That 3D model consists of cortical bone, cancellous bone, second premolar, first molar and second molar teeth. The 3D model of OMI was placed between root of second premolar and first molar teeth. The OMI was simulated with seven different angles of insertions: 30˚, 40˚, 50˚, 60˚, 70˚, 80˚ and 90˚. Within the seven different insertion angles, the results showed that the increase of insertion angle reduced the maximum equivalent von Mises stress in cortical bone, cancellous bone and OMI. Based on this FEA study, the optimal angle placement of OMI is when the implant positioned at vertical angle (90˚) to the bone surface.
Abstract: China currently is undergoing an unprecedented urbanization process which is accompanied by a severe damage to the environment. Cradle to Cradle Design approach has been gaining increasing interest among industries, authorities and consumers over these years. Its compelling design principles make people believe that adopting it in village planning or city planning is a very promising solution to China’s urbanization. This paper not only illustrates the features of ecovilllage and the design principles of Cradle to Cradle Design but also investigate the situation of first high-profile Cradle to Cradle planning project in China.
Abstract: Expert system using fault tree with a combination of mixed diagnostic method designed coin cell production line fault diagnosis system. It will describe the analysis of faults structure in the system. According to the hierarchical model of fault structure, it is divided into fault tree diagnosis section and expert system diagnostics section. And it will analyze the two diagnostic methods of reasoning mechanisms.
