Millimeter wave imaging is finding rapid adoption in security applications such as the detection of objects concealed under clothing. A passive system can be realized a stand-off type sensor that operate open spaces, both indoors and outdoors. In this paper, we address real-time outdoor concealed-object segmentation with radiometric operating W-band. The equipped dielectric lens receiver array at around 94 GHz. Images are analyzed by multilevel to identify object. Each level comprises vector...

Fairness is becoming an increasingly crucial issue for computer vision, especially in the human-related decision systems. However, achieving algorithmic fairness, which makes a model produce indiscriminative outcomes against protected groups, still unresolved problem. In this paper, we devise systematic approach reduces biases via feature distillation visual recognition tasks, dubbed as MMD-based Fair Distillation (MFD). While technique has been widely used general to improve prediction...

Millimeter wave (MMW) imaging is finding rapid adoption in security applications such as concealed object detection under clothing. A passive MMW system can operate a stand-off type sensor that scans people both indoors and outdoors. However, the often suffers from diffraction limit low signal level. Therefore, suitable intelligent image processing algorithms would be required for automatic recognition of objects. This paper proposes real-time outdoor concealed-object with radiometric...

Complex relationships among entities can be modeled very effectively using hypergraphs. Hypergraphs model real-world data by allowing a hyperedge to include two or more entities. Clustering of hypergraphs enables us group the similar together. While most existing algorithms solely consider connection structure hypergraph solve clustering problem, we boost performance considering various features associated with as well auxiliary Also, further improve if some labels are known and incorporate...

Recently, fairness-aware learning have become increasingly crucial, but most of those methods operate by assuming the availability fully annotated demographic group labels. We emphasize that such assumption is unrealistic for real-world applications since label annotations are expensive and can conflict with privacy issues. In this paper, we consider a more practical scenario, dubbed as Algorithmic Group Fairness Partially labels (Fair-PG). observe existing to achieve fairness perform even...

This article reports experimental and modelling results obtained with a small-scale standing-wave thermoacoustic engine. Reticulated vitreous carbon is used as the stack material atmospheric air working fluid. The engine tested resonators of variable lengths in range 57–124 mm. starts generating sound at temperature differences 200–300 °C between hot cold parts system. acoustic pressure amplitudes up to 2 kPa are measured inside resonator excited regimes. A simplified energy-balance theory...

In this pictorial, we depict our design process on gaming wearables starting from participatory workshops to concept creation. Wearables possess strong qualities for such as performativity, sociality and interactivity. However, it is an emergent field there a dearth of knowledge especially when comes designing mainstream platforms game consoles. Our aim explore elaborately with research through approach also clearly exemplify how progressed different phases. results, apart helping designers...

The design and development of playful wearable devices is a challenging complicated problem. It entails not only multidisciplinary expertise but also comprehensive understanding player experience. There scarcity evidence-based studies in current state-of-art literature that investigate general practices provide pragmatic implications suggestions based on solid user-centered research. To bridge the gap, we developed five experience prototypes speculative concepts from previous studies, Wizard...

Virtual environments are emerging as a tool for providing psychede-lic experiences due to the increasing interest in altered states of consciousness (ASCs) and spread VR headsets. However, user experience commercial psychedelic applications has not yet been adequately explored HCI. To fill this gap, we conducted study Cosmic Flow, one available on Steam. In exploratory study, six participants experienced Flow got interviewed. Analysis interviews revealed three main themes that articulate...

Energy of high-amplitude sound that often appears in acoustic resonators with mean flow can be harnessed and converted into electricity for powering sensors other devices. In this study, tests were conducted a simple setup consisting pipe pair baffles piezoelement. Tonal sound, corresponding to the second mode resonator, was excited due vortex shedding/impinging on presence flow. Generated energy partially electrical by About 0.55 mW electric power produced resistive load at pressure...

There are numerous benefits from regularly walking in nature, and today's mobile technologies have the potential to encourage people do so. Past research has showed that gamified map-based apps location-based games (LBGs) capability incentivize go nature areas cities beyond. In this study, we explored LBGs' bring by conducting a field experiment with new mechanic called Routes popular LBG Pokémon GO. Prior Route feature's launch, created altogether 13 of various lengths both city landscapes....

In this paper, we developed and experimented of the W-band 1-D focal plane array (FPA) passive imaging radiometer which was called by Millimeter-wave Imaging Radiometer Equipment (MIRAE). This consists quasi-optics including a dielectric aspheric lens metal mirror as reflector, 30 channels FPA receiver based on direct conversion type, scanner, image processor displayer. To get 2-D with 1 Hz frame rate, radiometric is moved into one direction linear scanner. From experiment results, it...

Following identification of a target protein, hit identification, which finds small organic molecules that bind to the target, is an important first step structure-based drug design project.

Water pharmacophore models are used screen compounds favorable given in large compound database,...

Millimeter wave (MMW) readily penetrates fabrics, thus it can be used to detect objects concealed under clothing. A passive MMW imaging system operate as a stand-off type sensor that scans people both indoors and outdoors. However, because of the diffraction limit low signal level, often suffers from image quality. Therefore, suitable computational processing would required for automatic analysis images. The authors present statistical algorithms their implementations real-time object...
