Artificial Intelligence (AI) is one such field; its applications are very extensive and interdisciplinary. The graduate students should especially be encouraged to learn various applications of contemporary computing techniques including artificial neural network (ANN), genetic algorithm (GA), etc. Civil/construction/ architectural Engineering has exercised a rapidly growing interest in the application of neurally inspired computing techniques. The motive for this interest was the promises of certain information processing characteristics similar to those of the human brain. Soft computing (SC) is an emerging approach to computing, which parallels to remarkable ability of the human mind to reason and learn in an environment of certainty and precision. This paper highlights various applications of AI in civil/construction/architectural engineering especially in SC areas. As an example of a graduate project, this paper demonstrated an ANN and GA based knowledge model where the customer’s preferences regarding comfort and safety issues in a large residential multistory flat housing scheme was studied. Architecture/engineering is an applied science where many lessons can be learned from existing structures, their successes and failures, and incorporating them to find out new techniques for a better structure. This implies that the designer should be able to derive from each previous design some qualitative values, especially on user’s approval regarding building’s safety and comfort quality as to assure a successful design. Architects/design engineers are quite often challenged with soft data, which are linguistic qualitative in nature, and needed to interpret and integrate into their design decision making processes. They should know much about their customer’s desires and requirements, and especially customer’s preferences when it comes to specific design issues. Hence, post-Proceedings This paper highlights various applications of AI through an example and referring other research papers. As an example of a graduate project, this paper demonstrated an ANN and GA based knowledge model regarding comfort and safety issues in a large residential multistory flat housing complex. Through post occupancy of building evaluation, the builders/designers able to assess what elements exceed customers’ expectations and are important in repeating in future projects, as well as the elements that fall short of expectations and may require modification for the next projects. During this process, designers are challenged with soft data, which are linguistic qualitative in nature, and needed to interpret and integrate into their design decision making processes.

Usually driving and learning through lectures and reading are passive or low stimulation activities. Therefore, they are highly sensitive to the accumulation of sleep debt. In November 2002 on Channel 11 News in Lubbock, Texas, it was reported that driving with 18 hours of sleep debt was equal to driving with 0.05 percent blood alcohol. The authors of this paper have developed a web-based interactive human performance sleep simulation model that considers inputs of sleep, alcohol, and caffeine to predict both active and passive performance efficiencies. A direct application can be made to predict active and passive learning. This simulation tool predicted a drop of about 55 percent in passive performance efficiency for both 0.05 percent blood alcohol and 18 hours of sleep debt. The simulation gives an 80 percent drop in efficiency for the combination of 0.05 percent blood alcohol and 18 hours of sleep debt. This paper will include information about the development and use of this model to improve student academic performance.","PeriodicalId":355306,"journal":{"name":"2003 GSW Proceedings","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130652476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Characterization of Symmetrical and Asymmetrical Polysilicon Surface Micromachined Electrothermal Actuators","authors":"W. Odom, E. Kolesar","doi":"10.18260/1-2-620-38506","DOIUrl":"https://doi.org/10.18260/1-2-620-38506","url":null,"abstract":"Several electrically-driven microactuators have been investigated for positioning individual elements in microelectromechanical systems (MEMS). The most common modes of actuation are electrostatic, magnetostatic, piezoelectric and thermal expansion. Unfortunately, the forces produced by electrostatic and magnetostatic actuators tend to be small, and to achieve large displacements, it is necessary to either apply a large voltage or operate the devices in a resonant mode. On the other hand, piezoelectric and thermal expansion actuators can be configured to produce large forces and large displacements. However, piezoelectric materials are not routinely supported in the fabrication processes offered by commercial MEMS foundries. These limitations have focused attention on thermally-actuated devices for generating the large forces and displacements frequently required to position and assemble complex MEMS. This investigation reports a new polysilicon electrothermal actuator design. In the traditional electrothermal actuator design, the single-hot arm is narrower than the cold arm, and thus, the electrical resistance of the hot arm is greater. When electrical current passes through the device (both the hot and cold arms), the hot arm is heated to a higher temperature than the cold arm. This temperature differential causes the hot arm to expand along its length, thus forcing the tip of the device to rotate about the flexure. The new double-hot arm thermal actuator design eliminates the parasitic electrical resistance of the cold arm by incorporating an additional hot arm. The second hot arm results in an improvement in electromechanical efficiency by providing a return current conductor that is also mechanically-active. Furthermore, in the new electrothermal actuator design, the rotating cold arm can have a narrower flexure compared to the flexure in the traditional device because it no longer needs to conduct an electrical current. The thinner flexure results in an improvement in mechanical efficiency. This research compares the performance of the single- and double-hot arm electrothermal actuator designs. Force and deflection measurements of both actuator designs as a function of arm length and applied electrical power are presented. The electrothermal actuator designs were accomplished with the MEMSPro ® software program, and they were fabricated using the MEMSCAP Integrated Microsystems Multi-User Microelectromechanical Systems (MEMS) Process ® (MUMPs) foundry at the Microelectronics Center of North Carolina (MCNC). development of integrated circuit microsensors, micromachining techniques applied to laser absorbers, advanced multi-chip module packaging technologies, solid-state gas chromatography systems, microelectromechanical systems","PeriodicalId":355306,"journal":{"name":"2003 GSW Proceedings","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123793658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Khraishi","doi":"10.18260/1-2-620-38499","DOIUrl":"https://doi.org/10.18260/1-2-620-38499","url":null,"abstract":"The engineering education literature, and other literature, is rich with references to the importance of Problem-Based Learning (PBL) in enhancing the educational experience of undergraduate students. In particular, PBL is supposed to strengthen concept learning in students. Such belief motivated the author to experiment with PBL in a required Dynamics class in the mechanical engineering (ME) department at the University of New Mexico (UNM). Due to the overall size of UNM and its mission, such a class typically involves a relatively large number of students (more than 40 typically). Such an enrollment figure encouraged the PBL experiment further since more interaction among students, or student groups, is probable and at least possible. The author found out that the most difficult part in the PBL experiment was picking one. The other thing found was that an extensive amount of effort went into making the experiment a successful one. The PBL experiment consisted of asking student groups to design an apparatus of some sort that is capable of shooting a golf ball in the air such that it lands in the middle of a sand-filled box at least one meter away. It was vital for the students to build their designs based on concepts learned in their Dynamics class and to explain, by equations, how their design works. The problem statement, as can be inferred, was open-ended and generated a spectrum of response from the students, i.e. different designs of the apparatus. A demonstration of all designs was held at the end of the semester. Although the students’ learning, at least some of them, was enhanced by this experiment, the results did not prove to be as optimistic as initially hoped. Many students made major assumptions, namely neglecting friction in the workenergy equation, without verifying that such an assumption was a good or bad one. Indeed, this assumption turned out to be a bad one for some of the designs. Other problems arose when some groups tried to use a spring mechanism to initiate ball flight. This and other issues like what lessons were learned from this experiment are discussed in the paper.","PeriodicalId":355306,"journal":{"name":"2003 GSW Proceedings","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116452060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the first few years, on the introduction of a new technology, it costs more than usual till when it gets into a manufacturing phase, and after that again cost goes up due to its obsolescence, whence further miniaturization has to set in. Financing is very different in the field of nano-engineering and difficult for an entrepreneur, as the financier or the funding agency wants to see what is the end product, after seeing what is going on. The lack of nano-engineering education-so called design fundamentals; knowledge of design tools and manufacturing processes is one of the major drawbacks. To add to it there is a lack of depository knowledge and infrastructure for selection of microfabrication processes and assembly. These deficiencies can be met, if during graduation from an undergraduate or a masters program, a broad based knowledge of nano-electronic fabrication technique is provided. This paper sets the limits and gives an overview of such a laboratory for a nano-technology research and infrastructure. This education can develop a technician-training program and ultimately leads to the capabilities of building proto-type pilot projects. Since upcoming initiatives are so demanding, newer systems prevent professors to form a company or participate with new entrepreneurs. One of the greatest examples is the long-standing demand of interconnections to nano-electronic components. Giving the right training and objectivity, a new generation of entrepreneurs can be enthused amongst our students. This would help our State develop fundamental research in nano-technology. Our effort of building a nano-engineering laboratory is to develop novel integrated Complementary Metal Oxide Semiconductor-CMOS gas sensors, SOI inertial sensors and piezoelectric tactile sensors based on piezo-resonance.
