Due to nonlinearity and uncertainty of induction cooker system, it is difficult to establish an accurate mathematical model for control purpose. This paper proposes an appropriate fuzzy control strategy for controlling pan temperature of induction cooker system, without an accurate control model. In induction cooker system, the temperature feedback is from the glass countertop instead of the pan....
Digital impressions of teeth, obtained through intra-oral scanning, allow for more efficient and cost effective treatments of many dental indications. Current state-of-the-art intra-oral impression acquisition systems make use of a separate monitor to show the scanning progress, forcing the dentist to divert attention away from the scanner and the patient. In this paper, we present an augmented reality...
Computer science education is still limited for middle school and high school students, while programming becomes an important skill to know. Therefore, students often have to rely on novice programming environments such as Scratch [1] and Hour of Code [2] and learn coding independently.
This installment of Notes from the Community covers wearables, low-power sensors, hacking, detecting and generating speech, election machines, and bathing suits.
One area in which glasses-based augmented reality (AR) is successfully applied in industry is order picking in logistics (pick-byvision). Here, the almost hands-free operation and the direct integration into the digital workflow provided by augmented reality glasses are direct advantages. A common non-AR guidance technique for order picking is pick-by-light. This is an efficient approach for single...
Multi-channel imaging like RGB is common today, however, a custom configuration of other modalities, such as wavelengths or polarization, is expensive and often unavailable. We propose a novel configurable multi-modal imaging system that solves this problem by using off-the-shelf components and proper fusion algorithms. The paper shows the application of polarization imaging for machine vision inspection...
The concept of augmented reality, which we have often heard about in recent years, means to reflect on the real world the objects created in the virtual environment with the help of mobile devices, to create a sense of reality. The concept of augmented reality, which allows many technological developments, has started to be used in many fields of education industry and applications have been made...
In the decommissioning of the nuclear power plant, especially, for decontamination by radioactive substances caused by 2011 Fukushima nuclear power plant accident has affected the reconstruction after the earthquake, the dose evaluation and validation of the decontamination effect is very important. In order to prepare a novel passive-type dosimeter system which can applied to radiation dose monitoring...
This paper reports on the design and experimental characterization of a higher-order wine glass (third order: WG3) mode MEMS square plate resonator to reduce the effect of fluidic damping and thereby enhancing the quality (Q) factor in water for biosensing applications. We show that the lateral strain profile of the WG3 mode is well suited for fully-differential piezoelectric transduction (which helps...
We report fabrication of grating with 7μm grating period inside the quartz g lass u sing femtosecond laser based micromachining system. Higher order grating with significant diffraction efficiency up to the 10th order has been achieved successfully.
We propose an extremely large mode-area compact hybrid multi-trench fiber with ∼40μm core at 1064nm. High-index arc in trench helps to achieve modearea of 1300μm2 at a practical bending radius of 7.5cm. Resonant rings and trench gaps maintain effectively single-mode operation and bending loss constraints.
This paper presents an experimental investigation of ultra-wideband (UWB) radio propagation through glass in the (3–8 GHz) frequency range using compact and cost-effective planar microstrip antennas. Channel parameters such as path loss magnitude, rms delay spread, received signal amplitude and multipath have been analyzed from the measured data. Results and analyses highlight the variation of the...
Paper provides an overview of passive thermographic analysis of photovoltaic panels. Operation state of real photovoltaic system, power plant ETFOS 1, is described through detailed thermographic documentation. The importance of education needed for correct measurement and interpretation of thermodynamic state of photovoltaic (PV) modules has been emphasized. Influences that can change apparent temperature...
Radiation cooling causes a non-uniform temperature field in the glass sample. In this case, heat flow arises in the sample and generates mechanical stresses and, as a consequence, optical anisotropy and birefringence. Modulation polarimetry technique for birefringence measuring was used. Phase differences between orthogonal components of linearly polarized light are linearly dependent on a stress...
On the benefit of the deeply development of MEMS and inertial instrument technology, the novel micro technology for positioning, navigation and timing (μΡΝΤ) becomes the substitution of GPS technology, and is the one of the most popular research area. The μ PNT unit volume can be pressed obviously by employing 3D stack technology after MEMS components are finished, and through silicon vias (TSV) technology...
A novel vibrating ring gyroscope is proposed in this paper, and the structure employs axisymmetric ring resonator and capacitance transducers. Motion characteristics of the ring resonator and the setting of the capacitance electrodes are discussed in detail. The simulation results demonstrate that the natural resonant frequency of the operating mode of the gyroscope is 8.805 kHz and 8.807 kHz, and...
This device includes a pair of glasses and an obstacle detection module fitted in it in the center, a processing unit, an output device i.e. a beeping component, and a power supply. The Obstacle detection module and the output device is connected to the processing unit. The power supply is used to supply power to the central processing unit. The obstacle detection module basically consists of a ultrasonic...
The Leopold and Rudolf Blaschka replicas of ma- rine invertebrates are among the more famous objects produced in the XIXth century for pedagogical purposes. Their high level of detail, still unknown manufacturing technique and their con- ceived artistic beauty, make these glass replicas precious museum exhibits currently. The fragility of these items produced by the Blaschka family (father and son)...
A single cycle laser pulse is generated using a two stage compressor consisting of a hollow core fiber and multiple fused silica plates. The single cycle laser pulse is sampled using the sub-cycle tunneling ionization in a gaseous medium or air.
There are a variety of learning resources with the potential to support children in learning programming independently. While many of them have been evaluated in laboratory settings, we know little about how children choose to use these resources on their own. We conducted a study organized around a film festival to explore children's open-ended use of four different learning supports: tutorials,...
