An investigation has been carried out on the control of a micro-droplet in electrostatic inkjet phenomena, because the electrostatic inkjet has a merit that the formation and locus of the droplet can be controlled by the application of the electric field and it is possible to treat highly viscous liquid. It was observed that a Taylor cone of the paste was formed at an end of a tube and the tip of the cone was broken to form a very small droplet at the beginning of the corona discharge. droplets of paste that contains Ag nanoparticles are injected on a glass substrate to form electrode patterns. The formation of the droplet is controlled by the application of pulse voltage between the plate electrode and the fine tube that is filled with Ag paste. A multi-layered printing was realized by over-coating insulative glass paste on line electrodes. A direct 3d printing was also developed by taking advantage that highly viscous liquid can be ejected by the electrostatic inkjet system.

Cross domain communication has been a long-discussed subject in the field of web-based application, especially for any sort of mashups where a single web app combines resources from different locations. This issue becomes more important in the web of Things context, where every physical resources are exposed to the web and mashed up by other web applications. In this paper we demonstrate a use case in which cross domain communication is applied in the web of Things using the HTML5 Cross document Messaging API (HTML5CdM). In addition, we contribute an advanced implementation of HTML5CdM that brings RESTful communication model to HTML5CdM and supports better concurrent message exchange, which we believe will be of much benefit to web developers. In addition, a time/space evaluation that measures CPU and Memory usage for the developed HTML5CdM library is carried out and the results has proved our implementation's practicability.

3d grey image segmentation has become a promising approach to facilitate practical applications with the help of advanced deep learning models. Although a number of previous works have investigated the vulnerability of deep learning models to backdoor attack, there is no work to study the severe risk of backdoor attack on 3d grey image segmentation. To this end, we propose two backdoor attack methods on 3d grey image segmentation, including Full-control Backdoor Attack (FCBA) and Partial-control Backdoor Attack (PCBA), on 3d grey image segmentation by leveraging a frequency trigger injection function and a rotation-based label corruption function. Our proposed trigger injection function is applied to insert a 3d trigger pattern into the benign 31) grey images in the frequency domain while ensuring the invisibility of the trigger pattern. And the proposed rotation-based label corruption function is employed to yield the crafted labels with the aim of decreasing the performance of segmentation. Finally, through comprehensive experiments on a real-world dataset, we demonstrate the effectiveness of our proposed backdoor models, the frequency trigger injection function, and the rotation -based label corruption function.

This paper presents a novel application of MEMS technology to the miniaturization of air-flow type fiber-generation technology. In Murata vortex spinning (MVS) machine, a nozzle for continuous air-jet blowing, which is the key component in producing fibers with distinctive nature, is equipped in the spinning chamber. With the intention of extending the MVS principle to smaller-scale fiber generation, we propose MEMS-based nozzles having 3d profile, transformed from conventional oblique jet holes with straight cylindrical shape. We design the nozzle geometry using computational fluid dynamics (CFd) simulations, and examine the applicability of presently fabricated nozzles to fiber generation through simplified experiments.

design of Test Structures for the Characterization of Thermal-Mechanical Stress in 3d-Stacked IC

IEEE TRANSACTIONS ON SEMICONdUCTOR MANUFACTURING 2012年第3期25卷 365-371页

In this paper, we present test structures and measurement techniques that enable the extraction of the significance of the thermal-mechanical stress in 3d-stacked integrated circuit technology. Heaters and integrated diodes have been used to determine the impact of hotspots in 3-d systems. The results obtained showed that in 3-d case, the peak temperature of a hotspot is three times higher compared to a traditional 2-d system. For the characterization of through silicon vias (TSVs)-induced stress and its impact on analog metal-oxide semiconductor (MOS) devices, a 10-bit current steering digital-to-analog converter (dAC) test structure is utilized. The dAC has been optimized to detect ion changes down to 0.5% due to TSV proximity, TSV orientation, thermal hotspots, and wafer thinning or stacking process. The results obtained from stand-alone short-channel MOS devices and the dAC structure clearly indicate the impact of TSV proximity and TSV orientation on the carrier mobility of nearby transistors.

Many family carers are single parents over the age of 60. despite poor health, the majority continue to care for a son/daughter with complex needs, such as intellectual disability, autism and cognitive deficits (hereafter referred to as Id). It is estimated that only 21% of these ageing carers have made adequate plans for the future care of their son or daughter. One significant barrier to future planning is a parent's fear that they will not be able to make regular visits to their loved one if he or she leaves the family home. People with complex needs are often placed in new residences that prove difficult or impossible for parents/guardians to access. This fear of separation can prevent carers from engaging in future planning. A review of modern communication technologies, for maintaining a distant caring/family relationship, reveals that 2d synchronous video based communication tools such as Skype and FaceTime do not represent a satisfying alternative to personal visits. It will be argued that 3d communication tools can form the basis for more fulfilling interactions. Three key differences have been identified between 2d and 3d communications that are relevant to maintaining family relationships: eye contact, touch, and the feeling of presence (sharing the same space). Addressing these differences, this paper offers an insight into advancing of 3d technologies for real time 3d scanning with real-time virtual, augmented, and mixed reality systems technologies, such as Microsoft's Holoportation. In addition, the haptic feedback options that are currently available for use with 3d systems and solutions are reviewed. The majority of haptic feedback devices have been developed for gaming application. However, typically, these products are not suitable for people with complex needs. A current technology review will be presented as a comparative analysis. A new communication system prototype designed specifically for people with complex needs, called embraceId, will be

A new concept for fiber-optical 3d shape sensing applying femtosecond laser technology for high-precision direct writing of Bragg gratings within the core and the cladding of single core standard telecom fibers is presented. This new technology enables a cost-efficient and real-time 3d shape sensing and navigation of medical catheters or endoscopes only by means of passive optical sensor elements. First prototypes showed the possibility to achieve absolute navigation accuracy of four mm per meter and have successfully been tested in clinical environment.

In the past, various studies have been proposed to acquire the capacity to perceive and comprehend language in articles or human communications. Recently, researchers focus on higher semantic levels to what human would need to understand the contents of articles. While human can smoothly interpret documents when they have knowledge of the context of documents, they have difficulty with those as their context is lost or changes. In this Phd proposal, we address three novel research questions: detecting uninter-pretable pieces in documents, retrieving contextual information and constructing compact context for the documents, then propose approaches to these tasks, and discuss related issues.

As the web evolves in an integrated and interlinked knowledge space thanks to the growing amount of published Linked Open data, the need to find solutions that enable the scholars to discover, explore and analyse the underlying research data emerges. Scholars, typically non-expert technology users, lack of in-depth understanding of the underlying semantic technology which limits their ability to interpret and query the data. We present a visual workflow to connect scholars and scientific resources on the web of data. We allow scholars to move from exploratory analysis in academic social networks to exposing relations between these resources. We allow them to reveal experts in a particular field and discover relations in and beyond their research communities. This paper aims to evaluate the potential of such a visual workflow to be used by non-expert users to interact with the semantically enriched data and familiarize with the underlying datas.

In microfluidic system, liquid handling is important to developing high-throughput drug screening, or constructing 3d cell culture platform. However, it was hard to expand this liquid patterning method to 3d system with conventional fabrication technology. Therefore, we suggest a novel concept for 3d patterning of liquid and hydrogel with adapting 3d printed micromesh structure and applied for complex microfluidic channel and 3d co-culture platform of multiple cell types. In addition, we proposed a method of forming a 3d blood vessel network by patterning hydrogel and endothelial cell inside a micromesh, showing the possibility of applying it to tissue engineering application. © 2019 CBMS-0001.
