Focused ultrasound with nanodroplets could facilitate localized drug delivery after vaporization with potentially improved in vivo stability, drug payload, and minimal interference outside of the focal zone compared with microbubbles. While the feasibility of blood-brain barrier (BBB) opening using nanodroplets has been previously reported, characterization of the associated delivery has not been...
On the aged society coming soon, many studies have explored homecare technologies. In this work, the activities at home are captured by a panoramic camera located at the center of a living room, and then analyzed and classified into standing, walking, sitting, falling, and watching television. First, the background subtraction scheme accompanied with shadow removal, and morphological operators of...
Attention plays a critical role in effective learning. By means of attention assessment, it helps learners improve and review their learning processes, and even discover Attention Deficit Hyperactivity Disorder (ADHD). Hence, this work employs modified smart glasses which have an inward facing camera for eye tracking, and an inertial measurement unit for head pose estimation. The proposed attention...
We report a frequency-domain method based on transmission line theory that we name ATLOG — Analytic Transmission Line Over Ground — to model finite or infinite wires interacting with a conducting ground excited by an electromagnetic pulse. This method allows for the treatment of finite or infinite lossy, coated wires above a lossy ground, as well as resting on or buried beneath the ground. Comparisons...
International Business Machines (IBM) points out that academics and industries pay a higher attention on "Service Science" since 1985. With the rotation of the wheel of a service era, many companies has driven from production to service-orientation, and focus on manufacturing services field. In the past, high-tech companies with leading technologies and unique products were ahead of other...
Clinical data shows that many oral cancers, car accidents and major accidental injuries cause to remove organs and limbs partially or completely due to incomplete physical appearance surgery. This is not only cause inconvenience to life, but also directly affects to patients' psychology and influences their job opportunities in the community. In the past, patients have been treated through Medical...
With the increasing complexity of electromagnetic environment and increasing intensity of military confrontation, the potential security exposure in the application of satellite navigation has become one real threat to face. This paper has an analysis on GNSS repeater spoofing technique, for fake Position, fake Time and fake Velocity in theory. The analysis results of this paper will provide beneficial...
This dissertation proposes an improved artificial bee colony (lABC) algorithm for designing a compensatory fuzzy logic controller (CLFC) in order to achieve an actual mobile robot wall-following task. During the wall-following task, the CFLC inputs measure the distance between the ultrasonic sensors and the wall, and the outputs of the CFLC are the robot's left-wheel and right-wheel speeds. A cost...
Resolving and identifying the structure and composition of atoms in a solid material at atomic resolution has been a long-standing goal of analytical microscopy. Controlling crystalline interfaces at the atomic scale is now actively being research in the broader range of materials science and device engineering fields. However, the atomic resolution of electron optics instrument was limited by the...
Ge n- and p-FinFETs with different interfacial layer ferroelectric HfZrOx (IL-FE-HZO) gate stacks have been demonstrated systematically by various annealing conditions for the first time. Microwave annealing (MWA) not only shows enhanced FE characteristics but also suppresses the gate leakage and Ge interdiffusion compared with conventional rapid thermal annealing (RTA). While HZO on Al2O3 IL results...
A tunable surface plasmon resonance (SPR) structure driven by microelectromechanical system (MEMS) is proposed and analyzed in this work. The MEMS isotropically expands the suspended SPR structures of nanometer metal disks scattered on a polydimethylsiloxane (PDMS) diaphragm, to different extents on the xy-plane; filtering the incident white light into various colors under control of applied voltage...
To date, dynamic vehicle routing problem (DVRP) has attracted great research attentions due to its wide range of real world applications. In contrast to traditional static vehicle routing problem, the whole routing information in DVRP is usually unknown and obtained dynamically during the routing execution process. To solve DVRP, many heuristic and metaheuristic methods have been proposed in the literature...
We investigate a novel Ti Chemical Vapor Deposition (CVD Ti) technique for source/drain and trench contact silicidation. This work is a first demonstration of a highly selective, superconformal Ti process that exhibits a low p-type CVD Ti/SiGe:B contact resistivity (pc) down to 2.1×10−9 Ω.cm2 (a 40% reduction vs. PVD Ti), matching the lowest published values [1-5]. A competitive n-type CVD Ti/Si:P...
Implementation of thick Cu inductor in IC chips has been a highly challenging task for Far-backend packaging industry. One of the major concerns is that the thicker Cu trace wrapped by re-passivation polymer layers (Polymer-1 & Polymer-2) is often accompanied by remarkable internal stress in the overall package, which is plagued with the risk of layer-to-layer delamination and/or interface micro-cracks...
Electromigration and resistivity of Cu, Co and Ru on-chip interconnection have been investigated. A similar resistivity size effect increase was observed in Cu, Co, and Ru. The effect of liners and cap, e.g. Ta, Co, Ru and SiCxNyHz, on Cu/interface resistivity was not found to be significant. Multilevel Cu, Co or Ru back-end-of-line interconnects were fabricated using 10 nm node technology wafer processing...
Consumption of ultrapure water (UPW) during semiconductor manufacturing processes is an important topic. A new design of water-dispensing arm employs a small volume of UPW to remove slurry residues inside pad grooves. This innovative water conditioning arm, in contrast to the conventional atomizer and diamond disc, not only reduces UPW consumption by 87% but also reduces scratch defects. The small...
The first dual-mode measurements of the time-varying radial and angular velocity signatures of a UAV quadcopter are presented. Measured with a compact 24 GHz interferometric radar, the signatures are measured at various observation angles relative to the UAV. It is shown that the signatures from the UAV at high grazing angles, when the radial velocity of the rotor blades relative to the radar is low,...
In the paper, radar micro-Doppler signatures of rotating rotors are investigated for detection and identification of small UAVs. A 24 GHz dual-receiving channel interferometric radar is used to capture useful features of rotating rotors. Interferometric radar with two receiving channels can measure both radial velocity and angular velocity induced micro-Doppler modulations. The study found the angular...
