Drivenby the ever increasing demand in function integration, more and more next generation high value-added products, such as head-up displays, solar concentrators and intra-ocular-lens, etc., are designed to possess freeform (i.e., non-rotational symmetric) surfaces. The toolpath, composed of high density of short linear and circular segments, is generally used in computer numerical control (CNC) systems to machine those products. However, the discontinuity between toolpath segments leads to high-frequency fluctuation of feedrate and acceleration, which will decrease the machining efficiency and product surface finish. Driven by the ever-increasing need for high-speed high-precision machining of those products, many novel toolpath interpolation and smoothing approaches have been proposed in both academia and industry, aiming to alleviate the issues caused by the conventional toolpath representation and interpolation methods. This paper provides a comprehensive review of the state-of-the-art toolpath interpolation and smoothing approaches with systematic classifications. The advantages and disadvantages of these approaches are discussed. Possible future research directions are also offered.

The fundamentals of graphical communication in order to help students think and communicate visually in the context of engineering design. The course focuses on concepts such as isometric, multi-view sketches, section view, and auxiliary views, tolerancing and dimensioning, as well as fundamentals of schematics and printed circuit boards design. Various computer aided design software are used. Students with credit for SEE 100 may not take this course for further credit.

The course teaches the fundamentals of graphical communication in order to help students think and communicate visually in the context of engineering design. The course focuses on representing three-dimensional objects in two dimensional space using various views, such as isometric, multi-view sketches, and section view, and auxiliary views. Tolerancing and dimensioning, as well as notation for manufacturing will also be discussed. Through the use of computer aided design (CAD) tools, students will apply the theory to real-world problems where they will be required to dissect, graphically represent, and redesign Mechatronic products.

When you complete the course, you would enhance your knowledge base, develop and hone investigation and problem analysis skills, be introduced to design and hone constraint identification and design generation skills, gain advance knowledge in SolidWorks and technical drawing as well as be introduced to the role of engineer in society.

Each student is responsible for his or her conduct as it affects the university community. Academic dishonesty, in whatever form, is ultimately destructive of the values of the university. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the university. -01.html

Students with a faith background who may need accommodations during the semester are encouraged to assess their needs as soon as possible and review the Multifaith religious accommodations website. The page outlines ways they begin working toward an accommodation and ensure solutions can be reached in a timely fashion.

This research paper presents a scientific attempt of a comprehensive systematic review of three-dimensional printing in geopolymer construction technology. The concept of 3D printing is an automated manufacturing process, layer- by- layer command, with computer-aided design model to create physical objects, acquiring swift development for the last few decades. An expansion of novel Geopolymer technology has been adopted in the construction and infrastructure industries for decades. The critical challenges of construction and infrastructure industries, such as the need for architectural, holistic, and rational designs, can be dealt with 3D printing techniques. Plentiful advantages of this emerging novel technology include a reduced amount of cost, ease of construction, a lesser amount of time, freedom of design, less wastage, aptitude to create complex structures, decrease in labor requirements, etc. Accordingly, The paper discusses common 3D techniques, such as Fused Deposition Modelling, Selective Laser Sintering, Stereolithography, 3D plotting, Laminated Object Manufacturing technique, Direct Energy deposition technique or laser engineered net shaping, Powder Bed Fusion and Inject Head 3D printing and direct deposition method. Overall, this study provides an introduction of 3D printing automation and robotics processes in a geopolymer construction industry. Ultimately, the paper emphasizes to motivate researchers towards future studies about 3D printing.

Concrete is most commonly and extensively used, a noteworthy and versatile building material for construction and infrastructure industries. Traditionally, Ordinary Portland Cement (OPC) is used as a predominant raw material in the form of a binder in OPC concrete. Undesirably, the present production process of OPC is not merely high energy-intensive, but it also emits a higher amount of carbon dioxide into the atmosphere and creates a serious global warming dilemma [1-3]. In this regard, it is necessary to search out other sustainable alternative materials that are significantly less energy-intensive with a low carbon footprint.

In 1978, French scientist Devidovits [4] invented a geopolymer - an inorganic material having non-crystalline structure, formed by source materials with rich silica as well as alumina content and alkaline solution by the process of geopolymerization. It is a geo-synthesis process that chemically combines silicon and aluminum rich products in an alkaline medium at room temperature [5]. The chemistry and reaction mechanism, explained by Davidovits [4], have resulted from the hydroxylation and poly-condensation of thermally activated kaolin (metakaolin) in an alkaline solution [6]. Thus, Geopolymers are synthesized by the activation of an aluminosilicate source, such as metakaolin, fly ash, slag, etc. with alkaline activators - formed by long-range and covalently bonded atoms, mainly silicon, aluminum and oxygen [7]. User-friendly alkaline reagents, such as sodium or potassium silicates, are useful in Geopolymerization [8-13].
