Full textAbstract:
Temperature distribution is an important process parameter of steel plates during electromagnetic induction heating treatment. This study uses the digital image correlation method to develop an effective non-contact temperature measurement that allows obtaining valuable information about the temperature value of a high temperature steel plate specimen and analyzing its temperature distribution. A principle of thermal radiation temperature measurement based on the color chagre couled device (CCD) technology was introduced. The image processing system encapsulates the image update module, form mode module, image event module and temperature analysis module. The error analysis and temperature calibration were carried out to make sure the error deviation of the measurement system was within a small range. The temperature distribution of B1500HS at high temperature was analyzed by the designed measurement system which was in good agreement with the result from Raynger 3i Plus temperature gun, indicating that the measurement system based on image processing basically meets the requirements of temperature distribution measurement of a high temperature steel plate, and provides an important reference for a high temperature steel plate in non-contact temperature distribution measurement.

Full textAbstract:
Understanding the root system architecture of plants as they develop is critical for increasing crop yields through plant phenotyping, and ultra-wideband imaging systems have shown potential as a portable, low-cost solution to non-destructive imaging root system architectures. This paper presents the design, implementation, and analysis of an ultra-wideband imaging system for use in imaging potted plant root system architectures. The proposed system is separated into three main subsystems: a Data Acquisition module, a Data Processing module, and an Image Processing and Analysis module. The Data Acquisition module consists of simulated and experimental implementations of a non-contact synthetic aperture radar system to measure ultra-wideband signal reflections from concealed scattering objects in a pot containing soil. The Data Processing module is responsible for interpreting the measured ultra-wideband signals and producing an image using a delay-and-sum beamforming algorithm. The Image Processing and Analysis module is responsible for improving image quality and measuring root depth and average root diameter in an unsupervised manner. The Image Processing and Analysis module uses a modified top-hat transformation alongside quantization methods based on energy distributions in the image to isolate the surface of the imaged root. Altogether, the proposed subsystems are capable of imaging and measuring concealed taproot system architectures with controlled soil conditions; however, the performance of the system is highly dependent on knowledge of the soil conditions. Smaller roots in difficult imaging conditions require future work into understanding and compensating for unwanted noise. Ultimately, this paper sought to provide insight into improving imaging quality of ultra-wideband (UWB) imaging systems for plant root imaging for other works to be followed.

Full textAbstract:
The article discusses a mathematical model of a hybrid system that combines photovoltaic and thermoelectric methods for converting concentrated solar energy into electrical energy. The specified mathematical model makes it possible to determine the temperatures of the photovoltaic module, as well as the temperature of the electrodes of the thermoelectric generator module. Optimal operating conditions have been determined for the hybrid system, taking into account the thermal contact resistance at the hot and cold sides of the thermoelectric generator. The simulation proceeded from the fact that only part of the absorbed solar radiation is converted into electricity due to the photoelectric effect, some part is lost due to radiation and convection from the upper surface of the photovoltaic module into the environment, and the rest is transferred to a thermoelectric generator connected to the lower part. photovoltaic module. A thermoelectric generator converts some of the thermal energy it receives from the photovoltaic module into electricity through the Seebeck effect, but most of it goes to the cooling system. The conversion of heat into electrical energy was based on the well-known Seebeck and Peltier effects. Along with these effects, such effects were taken into account as the formation of Joule heat due to the presence of electric current in the thermoelectric generator, Fourier thermal conductivity, as a consequence of the appearance of a temperature gradient in the transitions of a thermoelectric generator and Thomson heat, which arises both due to the presence of a temperature gradient, and electric current. The resulting model of the hybrid system makes it possible to study the effect of changing the temperature difference between the hot and cold electrodes of the thermoelectric generator and the resistance of the external circuit on the performance of the hybrid system. The model also allows the determination of the optimal operating conditions for the hybrid system, taking into account the thermal contact resistance on the hot and cold sides of the thermoelectric generator.

In this thesis, we use a cylinder lens to compress the laser beam into one-dimensional laser beam of line-light type, and by using a linear CCD to construct an optical type of simple object diameter measurement system. We use statistics and digital image processing to design the algorithm and software to precisely measure the object diameter. According to digital image processing, we have developed an edge detection algorithm to define the edge of object diameter and have used a standard of National Measurement Laboratory R.O.C (NML) to calibrate our algorithm and correct the systematic error. We estimated the correction factor, and used the method of statistics to add a algorithm to reduce the random error. Finally we calculated the total uncertainty for the measurement results. Experiments indicates that the optimal parameters of the measurement system are: (1) sampling time: 38 ms; (2) numbers of sampling : 81 times; (3) the input voltage of laser-beam module: 2.000 V. Experimental results show that the system uncertainty of the measurement system is 7 μm, which is small than one pixel size of the CCD. Using the correction factor to measure the diameters of 10 mm and 13 mm pin gauges, the uncertainties are 81 μm and 26 μm, respectively. According to the measurement results, we compared them with that of NML. The percentage errors are 0.82% and 0.25%, respectively. Experimental results also show that the simple-object diameter measurement system has the features of non-contact measurement, fast measurement ability and measurement with high accuracy. It is suitable to be applied to the production line to perform the automatic measurement of the size of objects diameter.

Find full textAbstract:
The manufacturing cost of solar cells along with their efficiency and reliability define the levelized cost of electricity (LCOE). One needs to reduce LCOE to make solar cells cost competitive compared to other sources of electricity. After a sustained decrease since 2001 the manufacturing cost of the dominant photovoltaic technology based on c-Si solar cells has recently reached a plateau. Further reduction in LCOE is only possible by increasing the efficiency and/or reliability of c-Si cells. Among alternate technologies, organic photovoltaics (OPV) has reduced manufacturing cost, but they do not offer any LCOE gain because their lifetime and efficiency are significantly lower than c-Si. Recently, perovskite solar cells have showed promising results in terms of both cost and efficiency, but their reliability/stability is still a concern and the physical origin of the efficiency gain is not fully understood.

MSOrgm raises its branches when it senses someone who is looking at it. MSOrgm was developed as a robot plant to interact with the viewer in a soothing way; it uses transformable module to build interconnected fabric and produce unexpected behavior. SSOrgan provides a novel tangible interaction, which generates color in response to touch. SSOrgan is an artificial skin system composed by dense individual sensing module; it creates the responsive behavior executed by its external contact and its internal computing mechanism. LBSkeleton explores a mutual interaction that happens between “the piper and the snake” ? through the change of the sound performance that should triggered by body movement reflectivity. LBSkeleton shows a kinetic structural system, which is engaged with the sensor networked framework and the origami tessellation module to perform a kind of growling behavior with sound. These works bring the specific type of modeling, controlling, and interacting on the designing of the kinetic creatures. The artworks are bringing novel user experiences with the biomimetic mechanism in a space.

Membrane distillation (MD) is a separation process used for water desalination, which operates at low pressures and feeds temperatures. Air gap membrane distillation (AGMD) is the new MD configuration for desalination where both the hot feed side and the cold permeate side are in indirect contact with the two membrane surfaces. The chapter presents a new approach for the numerical study to investigate various solar thermal systems of the MD process. The various MD solar systems are studied numerically using and including both flat plate collectors (the useful thermal energy reaches 3750 kJ/hr with a total area of 4 m2) and photovoltaic panels, each one has an area of 1.6 m2 by using an energy storage battery (12 V, 200 Ah). Therefore, the power load of solar AGMD systems is calculated and compared for the production of 100 L/day of distillate water. It was found that the developed system consumes less energy (1.2 kW) than other systems by percentage reaches 52.64% and with an average distillate water flow reaches 10 kg/h at the feed inlet temperature of AGMD module 52°C. Then, the developed system has been studied using TRNSYS and PVGIS programs on different days during the year in Ain Temouchent weather, Algeria.

This paper provides an evaluation of the effectiveness of a year-one module delivered by a combination of traditional and online teaching methods to leisure and tourism undergraduates. The research further considers the value of the extemporized implementation of computer-mediated instructional settings that do not consider or refer to existing evaluative frameworks, in view of the fact that initiatives often are driven more by pragmatism and policy than pedagogy and theory. The findings show that there are negative and positive attributes to both methods of instruction, but overall, traditional methods are seen as preferable to new online developments. The reasons for this preference are explored and include communication interaction and contact with a tutor. The main positive attributes of the online system are flexibility and accessibility. The issue of appropriateness of online instruction at differing higher educational levels is also considered.

Abstract Computational fluid dynamics (CFD) simulations were carried out to study the performance of a single hollow fiber in a direct contact membrane distillation (HF-DCMD) module for a desalination process. The feed solution is seawater with a salt (NaCl) concentration of 35 g/L. The Navier-Stokes, mass and energy transport equations are considered, with a coupled boundary condition imposed by the membrane. The system is investigated to examine sensitivity toward the membrane thickness, pore size, and inner hollow fiber diameter based on existing commercial fibers. Two membrane thicknesses (300 μm, 500 μm), two membrane pores sizes (0.2 μm, 0.45 μm), and two inner diameters (1.2 mm, 1.8 mm) are studied in the laminar regime at fixed operating conditions. The presence of temperature polarization causes a significant drop in the water permeation in the DCMD system due to reduced driving force across the membrane. The characterization of polarization inside the hollow fiber will be the focus of this work. It was found that the vapor flux was most sensitive to the membrane thickness (a 30% flux increase) versus the inner diameter (2% flux increase). The pore size is also a very influential parameter (20% flux increase), moving from optimal to less-optimal properties.

For applications such as cooling of electronic devices, it is a common practice to sandwich the thermoelectric module between an integrated chip and a heat exchanger, with the cold side of the module attached to the chip. This configuration results thermal contact resistances in series between the chip, module, and heat exchanger. In this paper, an appraisal of thermal augmentation of thermoelectric module using nanofluid-based heat exchanger is presented. The system under consideration uses commercially available thermoelectric module, 27nm Al2O3 - H2O nanofluid, and a heat source to replicate the chip. The volume fraction of nanofluid is varied between 0 to 2%. At optimum input current conditions, experimental simulations were performed to measure the transient and steady-state thermal response of the module to imposed isoflux conditions. Data collected from the nanofluid-based exchanger is compared with that of deionized water. Results show that there exist a lag-time in thermal response between the module and the heat exchanger. This is attributed to thermal contact resistance between the two components. A comparison of nanofluid and deionized water data reveals that the temperature difference between the hot- and cold-side, ΔT = Th − Tc ≈ 0, is almost zero for nanofluid whereas ΔT > 0 for water. When ΔT ≈ 0, the contribution of Fourier effect to the overall heating is approximately zero hence enhancing the module cooling capacity. Experimental evidence further shows that temperature gradient across the thermal paste that bonds the chip and heat exchanger is much lower for the nanofluid than for deionized water. Low temperature gradient results in low resistance to the flow of heat across the thermal paste. The average thermal contact resistance, R = ΔT/Q, is 0.18 and 0.12 °C/W, respectively for the deionized-water and nanofluid. For the range of optimum current, 1.2 ≤ current ≤ 4.1Amp, considered in this study, the COP ranges between 1.96 and 0.68.

Full textAbstract:
Many traditional macro scale finite element models of thermal contact systems have incorporated the effect of micro scale surface topography by applying a constant value of thermal contact conductance (TCC) per unit area to the regions in contact. However, it has been very difficult to determine an appropriate TCC value for a given system and analysts typically had to rely on experimental data or values from the literature. This work presents a method for predicting micro scale TCC per unit area by incorporating micro scale surface roughness in a multi-scale iterative thermal/structural finite element contact model. The resulting TCC value is then used in a macro scale thermal/structural contact model with apparent surface form to predict the thermal contact resistance and overall thermal resistance for a commercial power electronics module.

Full textAbstract:
In this paper, we present the development of a tire deformation sensing system that can provide the critical information for estimation of tire/road interaction for mobile robots and vehicles. Polyvinylidene fluoride (PVDF)-based sensor is designed and fabricated to embed on the inner tread surface to measure the rubber tread deformation. Analytical models of the PVDF-based sensing system are presented to capture the tire/road contact information and friction characteristics. The sensed deformation measurements are integrated with the on-board control system through a wireless data transmission module. Experimental results on a skid-steered mobile robot are presented to show the feasibility of the developed sensing system.

Full textAbstract:
Surface failure in the form of pitting wear is encountered in cam-roller systems. The failure appears to be initiated at micron-scale subsurface region. High stress is a result of the macro-scale requirement on the cam-roller motion event that produces high contact loads due to inertia of the roller and its follower link. Sliding of the roller and its impact onto the cam surface further compounds the detrimental effect of contact load. While conventionally a Hertz contact stress analysis can be used in ascertaining contact stress and maximum subsurface von Mises stress, it generally underestimates the stress when compared to the micron-scale subsurface stresses due to the presence of surface roughness. Contact analyses of cam and roller with rough surfaces are performed to examine the effects of two surface treatments. These involve surface finishing process in which a surface is rendered smooth, and the addition of a coating to the roller surface. Measurements of such cam and roller surfaces are used in micro-contact analysis module of Surface Distress Analytical Toolkit (SDAT) to examine the effect of surface finish and coating on maximum subsurface stress. It is found that smooth surface provides a 53% reduction in maximum subsurface stress. The analysis also shows that the addition of coating reduces subsurface stress nearly 7%. The impact of the combined treatment of the surface is an increase in fatigue life of the cam-roller system by nearly two orders of magnitude. The above findings are based on laboratory tests using six rollers without and with various degrees of finishing processes, and with and without addition of coating to the surfaces. Examination of the rollers indicates a general improvement in roller performance due to addition of coating. Most notably, the combination of finishing process and coating was found to provide the best fatigue life since the corresponding rollers showed no observable wear even after testing for 2161 hours, or the same number of cycles accumulated over about 500,000 truck miles.

Abstract Dimensional metrology is an integral part of quality control in manufacturing systems. Most existing manufacturing systems utilize contact-based metrology, which is time consuming and not flexible to design changes. There have been recent applications of computer vision for performing dimensional metrology in manufacturing systems. Existing computer vision metrology techniques need repeated calibration of the system and are not utilized with data analysis methods to improve decision making. In this work, we propose a robust non-contact computer vision metrology pipeline integrated with Computer Aided Design (CAD) that has the capacity to enable control of smart manufacturing systems. The pipeline uses CAD data to extract nominal dimensions and tolerances. The dimensions are compared to the measured ones, computed using camera images and computer vision algorithms. A quality check module evaluates if the measurements are within admissible bounds and informs a central controller. If a part does not meet a tolerance, the central controller changes a program running on a specific machine to ensure that parts meet the necessary specifications. Results from an implementation of the proposed pipeline on a manufacturing research testbed are given at the end.

Abstract Polishing is an important process performed in the finishing and repair processes of mechanical parts and is still a manual work of skilled workers. However, in addition to the time and cost required for manual polishing, there are also problems such as a decrease in the number of workers and health hazards due to dust generated during polishing. From these problems, the demand for automatic polishing is increasing at manufacturing sites. To automate polishing process, a macro-micro system based polishing robot which consists of a functional end-effector and industrial robot has been proposed. Regarding end effectors, mechanical design aiming for high rigidity and motion control methods for keeping the contact force constant is being researched. Meanwhile, the tool rotation speed of the spindle is independently controlled typically. Therefore, in this research, a functional polishing module capable of polishing force control and tool rotation control according to the tool feed rate is developed as the end effector. For the polishing automation, the macro-micro system based polishing robot is constructed attaching the polishing module to the industrial robot. From the viewpoint of Preston’s law, the effectiveness of the robot polishing is investigated through polishing experiments and measuring the shape of the polished surface.
