This paper proposes a contactless charging platform with reconfigurable coils which compose a hexagonal coil array complied with wireless power consortium A3 standard. The function of contactless charging platform (CCP) that switches one of them to excite is to avoid the current cancellation phenomenon and to prevent the magnetic field attenuation. The CCP transmits wireless power to the secondary...
Crosstalk noise is a potential issue for optical router used by optical network-on-chip (ONoC). The huge crosstalk directly degrades the performance in optical signal-to-noise ratio (OSNR) at optical router level, and greatly limits the scalability at ONoC level. This paper proposes ILCOR, a low-crosstalk optical router using multi-layer coupled MR. The use of multi-layer coupled MR enables less waveguide...
with the extending of the storage space capacity of semiconductor device, more and more important data in the business have been accumulated in the device. Thus, the security enhancement becomes the crucial thing must be solved. Fingerprint, due to its properties of “unique by individual” and “unchangeable through life” as well as free from entering password turns into the first choice of personal...
Nowadays, users are relying on mobile service ecosystem for their daily life, while there is a lack of support for users to efficiently migrate their tasks across different terminals. Furthermore, the same application running on different terminals may even have different layouts to guarantee the user experience, which makes the migration more difficult. To facilitate the switching among multiple...
Churn prediction is very important to the insurance industry. Therefore, there is a big value to investigate how to improve its performance. More importantly, a good model can be used by a common service provider and benefit many companies. State-of-the-art methods either use 1) shallow models such as logistic regression, with sophisticated feature engineering, or 2) deep models that learn features...
Wireless sensor network (WSN) plays an important role in monitoring applications in many areas. This paper presents a WSN called EN-Nets which is based on a newly designed small-size and low-power sensor node (EN-Node) for monitoring real-time environmental conditions. Detailed design and implementation of the sensor node for sensing and communicating environmental parameters are described. A power...
Nowadays many companies and organizations choose to deploy their applications in data centers to leverage resource sharing. The increase in tasks of multiple applications, however, makes it challenging for a data center provider to maximize its revenue by intelligently scheduling tasks in software-defined networking (SDN)-enabled data centers. Existing SDN controllers only reduce network latency while...
As the quantity of Web services grow continuously, it becomes more challenging for developers to navigate through and make use of them. Thus, a knowledge map consisting of a summary of individual services and their relations has become increasingly useful. There are two challenges in building such a knowledge graph for Web service ecosystems. First, services keep evolving in terms of function and...
With the rapidly increasing number of services, there is an urgent demand for service recommendation algorithms that help to automatically create mashups. However, most traditional recommendation algorithms rely on the original service descriptions given by service providers. It is detrimental to the recommendation performance because original service descriptions often lack comprehensiveness and...
Whether superposition (source separation) Is optimal for the asymmetric multilevel diversity coding systems (AMDCS) with perfect secrecy is answered in this paper by studying a non-trivial example. Threshold perfect secrecy is added to the AMDCS model. The eavesdropper may have access to any one but not more than one subset of the channels but can get nothing about the sources, as long as the size...
A service ecosystem, consisting of various kinds of services and mashups, evolves over time. Existing works on the evolution of service systems focus on either evaluating the impacts of services' changes on the usage of services and the stability of the whole ecosystem, or discovering co-occurrences between services, but fail to disclose any knowledge about the evolution of service composition patterns...
Service recommendation plays a critical role in fostering the growth of service ecosystems. However, existing methods are mainly in favor of a small number of popular services while newly emerged ones (i.e., newborn services) are largely ignored, which hurts the systems in two aspects. First, the potential of many services, especially the newborn ones, is wasted. Second, service ecosystems highly...
This paper aims to evaluate Tenax TA in the form of thin films as an adsorbent material as an alternative to its solid form counterpart (granular form) for micro-preconcentrators. The micro preconcentrator (μPC) consists of embedded high-aspect-ratio three-dimensional micro-pillars coated with Tenax adsorbent. This μPC has inner dimensions of 5 mm × 5 mm with a total inner volume of ∼6.5 μL. This...
Growing mobile data usage has led to end users paying substantial data costs, while Internet service providers (ISPs) struggle to upgrade their networks to keep up with demand and maintain high quality-of-service (QoS). This problem is particularly severe for smaller ISPs with less capital. Instead of simply upgrading their network infrastructure, ISPs can pool their networks to provide a good QoS...
Provides an abstract for each of the keynote presentations and a brief professional biography of each presenter. The complete presentations were not made available for publication as part of the conference proceedings.
Internet service providers (ISPs) struggle to invest in upgrading their networks to catch up with growing mobile data demand, while users have to face significant data overage fees. Pooling ISPs' network infrastructures can potentially enable better user experience and lower prices. For example, Google recently launched a cross-carrier MVNO (mobile virtual network operator) data plan called Project...
In this paper, different type of wax, wax content and hot hardness at 175°C on the release force and adhesion of molding compound were studied, The studies reveal that the hot hardness is playing a very important role to balance the conflict of reliability and moldability. With higher hot hardness of epoxy molding compound, the release force can be kept at same level with less wax content which can...
Epoxy molding compound for LED bracket, with the merits of good resistance to heat and light damage as well as good reliability and warpage compared to traditional thermoplastic reflecting materials for LED bracket, such as Polyphthalamide (PPA) and Poly1,4-cyclohexylene dimethylene terephthalate (PCT), has becoming the focus of researchers. Here we studied the reflectance of the white epoxy molding...
In the photovoltaic (PV) emulator application, an accurate PV mathematical model is needed to ensure the emulator can produce the same current-voltage (I-V) characteristic of a PV panel. The PV circuit model is able to simulate the PV panel accurately. However, this model requires the numerical method to solve the implicit equation of the model and the complex parameter extraction can burden the PV...
Alternative energy systems (AES) are becoming popular for small scale power generation. Designing the converters which transform the DC power into AC is the main development area of AES. Conventional single-phase voltage source inverter (VSI) uses buck topology which gives lower average output voltage than the input DC voltage. However, where the output voltage requirement is larger than the input...
