Different from the traditional subtractive manufacturing, additive manufacturing - a more flexible and material saving manufacturing technology has been developed in these recent years. This paper presents a simulation and optimization framework for Additive Manufacturing (AM) processes in practical industry. Starting from multi-level part design, to process optimization and planning, from energy and material consumption to the Key Performance Indicator (KPI) evaluation, the paper presents a complete practical working flow of AM technologies. Four models are developed within the framework: the design model, the process optimization and planning model, the energy and material consumption model and the production model. All the four models connect subsequently one another. Their concepts and corresponding methods will be presented in order in each chapter of the paper. A close optimization loop can be formed by these models. The feedbacks of each model will be used to optimize the design as well as the process planning. Preliminary experiments data are generalized and analysed by each model.

This paper presents a selective authentication watermarking algorithm for 2D CAD engineering drawings based on entity localization. Firstly, get the vertexes of each entity and map them to log-polar coordinates, the sum of amplitude before accuracy and handle of previous entity is used to generate a watermark. Then use the improved difference expansion (IDE) algorithm to embed the watermark into corresponding amplitude. Theoretical analysis and experimental results show that the proposed algorithm is not only robust against global geometric operations such as translation, rotation and scaling, but extremely sensitive to malicious attacks which affect the normal use of drawings, meanwhile it can also locate tampering to a specific entity. It provides an effective method for integrity authentication of engineering drawings.

Structural steel transport is an important aspect of the construction and steel industries. It is surprising to find that structural steel packing is still done empirically by experienced workers. Therefore, this paper explores how this problem is currently dealt with in steel plants to document the loaders' reasoning, since no literature on the subject has been found. Such documentation could later help the development of an algorithm capable of planning these packings. Expert loaders' reasoning was captured through an experiment exploiting a set of miniature members representing structural steel members. Miniature members were created using additive manufacturing. This miniature set was then used to interview steel loaders and document their vocabulary, process, rules and reasoning.

Near-infrared spectroscopy(NIRS) technique uses specific wavelengths of light to make a continuous and noninvasive brain monitoring possible. It has great prospects in biomedical monitoring. We have designed and implemented a NIRS prototype system, with which we recorded the concentration changes of oxyhemoglobin(O2Hb) and deoxyhemoglobin(CO2Hb) during in-vivo experiments. The results showed that this prototype based on NIRS technique has a good performance on detecting biomedical signals about hemodynamic changes in brain.

A regular four-axis computer numerical control (CNC) machine is always used to produce blades by spiral machining method in many medium-sized and small industries. Generally, the four-axis CNC machine has the characteristic of low precision, which often leads to some obvious tiny tool marks like overcut on the blade surface. To overcome this problem, a tool orientation smoothing method is developed and implemented. Key issues are focused on tool orientation smoothing in four-axis spiral machining of blades, and concrete contributions are twofold. First, according to the primary curvature radii and parameter characteristics, the parameter range of blade surface is subdivided into four subregions. Second, tool orientation smoothing method for four subregions of blade surface is addressed in detail based on the step length of cutter contact (CC) points in four-axis spiral machining. A test shows that tool marks that easily occur in four-axis machining can be effectively reduced by using the proposed method.

This paper is a preliminary study on improving the efficiency of recruiting in a staffing agency. Statistics show that the revenue of Canadian recruitment industry has increased sustainably in recent years and the contribution of temporary staffing services have reached approximately two-thirds of the whole recruitment industry sales. However, in the information explosion ages, how to improve the efficiency of recruiting is a critical challenge facing the staffing agencies. Traditional recruitment process is neither effective nor efficient in matching the large pool of candidates. Internet-based recruitment solutions can be very efficient in dealing with large-scale datasets but still have some problems. In order to know better about the design prolem and to gather more requirements, the authors introduce an emerging and promising Environment-Based Design methodology to conduct the environment analysis activities so as to find out the key environment components for the design problem and the relationships between the environment components.

The purpose of this paper is to provide a systematic algorithm to identify conflicts implied in a product-environment system (PES). A PES is generated from environment analysis, the first activity of EBD methodology. Conflict identification is the second activity in EBD methodology. A detailed systematic approach to identify conflict is missing in this activity; therefore, the proposed algorithm is intended to close this gap. The algorithm includes the following tasks: 1) construct a performance network, 2) identify active and reactive conflicts, and 3) identify critical conflicts. A case study in collaboration with Area Development Planning (a subsection of the City of Edmonton) is also presented in this paper. The case study is to demonstrate the use of the proposed algorithm to develop a total quality management system. The algorithm lays the foundation for solution generation, which is the third activity in EBD methodology.

This article have presented a non-contact vibration sensor based on FBG sensor, and used it to monitor the vibration of rotating shaft. In this article, we described the principle of the sensor and made an experimental analysis. The analysis results showed that the sensitivity and linearity of the sensor were -1.5pm/um and 4.11% respectively within a measuring range of 2-2.6mm. When the sensor was used to monitor the vibration of the rotating shaft, the vibration signals and the critical speed measured were the same as that obtained from the eddy current sensors. This indicated that the sensor could be effectively used for non-contact measurement of vibration of rotating shaft, and fault monitoring and diagnosis of rotating machinery.

We intend to develop a computer-aided design (CAD) system that takes design problem definitions as input and presents a set of geometries that solves the problem. For such system, we perceive using a controlled natural language (CNL) as one method within a multimodal interface to capture some of the required input. To evaluate the feasibility of using a CNL for problem definitions, we conducted a user study with 18 participants. We found that using a CNL increases the quality of problem definition statements for functional requirements compared to statements written in natural language. While a CNL limits the breadth of problem definitions, it can achieve a balance between natural expression and formal specification of problem definitions.
