Touches between the fingers of an unencumbered hand represent a ready-to-use, eyes-free and expressive input space suitable for interacting with wearable devices such as smart glasses or watches. While prior work has focused on touches to inner surface hand, nails, practical site mounting sensing hardware, have been comparatively overlooked. We extend implementations single touch nails full set five explore their potential input. present design ideas 144 (taps, flicks swipes) derived from...

Hybrid copper bonding (HCB) technology has been introduced and evaluated to overcome a fine pitch limit degradation in thermal properties 3D semiconductor package structure. In this study, we successfully demonstrated memory stacking by HCB which integrated Cu-Cu diffusion along with oxide simultaneously. process was developed die-to-wafer (D2W) multi-stack structure realized shows excellent electrical properties. The flatness of the surface controlled chemical mechanical polishing (CMP),...

Wi-Fi round-trip timing (RTT) was applied to indoor positioning systems based on distance estimation. RTT has a higher reception instability than the received signal strength indicator (RSSI)-based fingerprint in non-line-of-sight (NLOS) environments with many obstacles, resulting large errors due multipath fading. To solve these problems, this paper, we propose high-precision RTT-based system using an compensation network (RCDN) and region proposal (RPN). The proposed method consists of...

Swallowing impairment after stroke may be related to the state of corticobulbar tract (CBT), which is motor projection fiber responsible for deglutition, but evidence still lacking regarding parameter could relate poststroke swallowing recovery as measured by videofluroscope findings. This prospective study evaluated diffusion tensor imaging (DTI) parameters among dysphagic patients compared with those nondysphagia and age-matched healthy subjects followed in assessed Modified Barium Swallow...

In order to utilize network resources efficiently and reduce regional congestion, associating mobile stations (MSs) with proper base (BSs) is of crucial importance in wireless cellular networks. There have been several load-aware proposals literature, where most are classified into so-called closed-form approaches. such approaches, each MS independently deterministically selects the BS which expected provide highest throughput. The throughput estimated by a equation based on assumption...

Image captions aim to generate human-like sentences that describe the image's content. Recent developments in deep learning (DL) have made it possible caption images for accurate descriptions and detailed expressions. However, since DL learns relationship between captions, constructs based on commonly frequented words dataset. Although these generated are highly accurate, they low lexical diversity, unlike humans due limited vocabulary. Therefore, this paper, we propose a Part-Of-Speech...

We examined the surface segregation behavior of Si in amorphous AuSi alloys using ab initio molecular dynamics simulations within density functional theory. For a thin Au70Si30 film, our predict enrichment that leads to stoichiometry close Au60Si40 layer. The structure exhibits rather ordered Au3Si2 phase, which somewhat differs from bulk tendency random hard-sphere packing. also discuss origin based on analysis segregation-induced changes atomic and electronic alloy surface.

Based on mechanism previous model IV, we developed new by using differential driving mechanism, so that just simply controlling speed each units helps to travel effectively pipelines. Furthermore, uses clutches in transmitting power wheels. clutch enables select suitable method according shape pipeline. In this paper,...

Recently, the specifications for 5G system architecture and procedures including TS 23.501 23.502 are being developed by 3GPP. In specifications, one of key principles concept is to separate user plane (UP) functions from control (CP) functions, allowing independent scalability, evolution flexible deployments modularize design enable efficient network slicing. Therefore, a lot new (NFs) has been newly discussed specified, such as AMF, SMF, UPF, NRF, NEF, etc. this regard, it important see...

Growth of metallic nanorods by physical vapor deposition is a common practice, and the origin their dimensions characteristic length scale that depends on three-dimensional Ehrlich-Schwoebel (3D ES) barrier. For most metals, 3D ES barrier large so order 200 nm. Using density functional theory-based ab initio calculations, this paper reports Al small, making it infeasible to grow nanorods. By analyzing electron distributions, shows small result covalent bonding in Al. Beyond infeasibility...
