The cloud manufacturing yields insights of manufacturing services over cyber space based on integration of advanced manufacturing with cloud computing. However, the different communication standards between the different system levels are main challenges for the integration of them without a conflicting communication. Ethernet appears as the best solution to support all levels for industrial manufacturing...
Welcome to the 35th edition of the International Conference on Computer-Aided Design! For the second year in a row, ICCAD is held in Austin, Texas. Jointly sponsored by IEEE and ACM, ICCAD is the premier forum to explore emerging technology challenges, present cutting-edge R&D solutions, record theoretical and empirical advances, and identify future roadmaps for design automation and other system-on-chip...
A vacuum deposition process is developed to fabricate high efficiency perovskite solar cells with high stability using alternating layer-by-layer vacuum deposition. The power conversion efficiencies for the planer device is as high as 19.4% on rigid glass substrate and 15.1% using flexible polymeric substrate, both are the highest reported to date for their respective categories. Meanwhile, the devices...
By performing spatially resolved Raman and photoluminescence spectroscopy with different illumination conditions, we have achieved a unified understanding towards the spectroscopy signatures of the organic-inorganic hybrid perovskite, transforming from the pristine state (CH3NH3PbI3 or MAPbI3) to fully degraded state (i.e., PbI2), for samples with varying crystalline domain size from mesoscopic scale...
The energy band diagram of the HIT solar cell obtained using AFORS-HET simulations reveals that a p-type inversion layer is induced in the n-type c-Si near the front hetero-interface. The HIT solar cell actually behaves like a "pseudo" p-n homojunction solar cell, in which the p-type inversion layer acts as the cell emitter and controls the performance of the solar cell. The formation of...
A recently developed approach to precision medicine is the use of Markov Decision Processes (MDPs) on Gene Regulatory Networks (GRNs). Due to very limited information on the system dynamics of GRNs, the MDP must repeatedly conduct exhaustive search for a non-stationary policy, and thus entails exponential computational complexity. This has hindered its practical applications to date. With the goal...
A set of principle design decisions drives architects to design software architecture for a system satisfying requirements. The design decision making process involves a group of stakeholders exchanging their viewpoints to address various concerns and reach a consensus. Often the architecture rationale behind various design decisions is not fully captured and hence affects the maintainability of software...
The growing number of Additive Manufacturing Web (AMW) services, offered by different providers over the Internet, makes it challenging for consumers to compare these AMW services to select a service of their choice. In addition, it is even more challenging for consumers to compare these AMW services against their personal preferences. This is because, consumers personal preferences on multiple non-functional...
Existing service recommendation methods, that employ memory-based collaborative filtering (CF) techniques, compute the similarity between users or items using nonfunctional attribute values obtained at service invocation. However, using these nonfunctional attribute values from invoked services alone in similarity computation for personalized service recommendation is not sufficient. This is because...
In this paper, we describe an efficient method for creating mosaics from collections of videos. Our method is based on a utility maximization formulation which we optimize greedily. We employ a function for quickly estimating mosaics without computing image features that allows us to efficiently take greedy steps while still achieving user definable goals for mosaic quality. Indeed, we demonstrate...
In this paper, we describe the design of a 3 Giga-samples per second real-time multi-channel data-acquisition unit. We first introduce the technical challenges including synchronization, data transmission and printed circuit board design. Then we analyze the cause of issues in multi-channel synchronization, and develop a novel method to synchronize the channels and correctly save the data into RAM...
Sensitivities of the dynamic system responses with respect to the system parameters are highly valuable, with broad applications such as system tuning and uncertainty quantification. Compared to the direct methods, adjoint methods are much more efficient when the number of parameters is large. In this paper, we present a time-unrolling method to compute adjoint sensitivities. Instead of explicitly...
Intelligent argumentation system facilitates stakeholders to exchange dialogue over issues and provides decision support by capturing rationale of the stakeholders through arguments. In argumentation process, stakeholders tend to polarize on their opinions and form polarization groups. A method [1] was developed earlier to identify polarization groups, however, polarization groups tend to overlap...
This paper presents the first computer aided software analysis tool based on HOOMT (High Order Object-oriented Modeling Technique), which provides facilities for structured object-oriented analysis by integrating structured analysis and object-oriented analysis. It contains a graphical user interface for HOOMT-based modeling, supports modeling information management, and provides functionalities for...
With the rapid growth in the number of available services, recommending suitable services to users becomes increasingly important. A number of collaborative service recommendation methods based on user experiences have been proposed for this purpose. Most of them adopt the similarity-based Collaborative Filtering (CF) technique, which tends to identify similar users for a target user and recommends...
Perception of trustworthiness of service providers is a fundamental need in service selection. Trust propagation has been used to predict trustworthiness of service providers in service-oriented social networks. However, existing trust propagation methods may suffer from a scalability problem, i.e., their computation time is likely too high to be acceptable in practice, especially when they are applied...
Recent innovations in semiconductor processes have accelerated the transition from analog circuits to their digital counterparts, with digital PLLs (DPLLs) being an example of this trend [1]. All-digital or fully synthesizable approaches, which exploit the merits of advanced processes, suffer from poor noise performance and high power consumption [2]. On the other hand, hybrid approaches, which employ...
With the number of services with similar functionalities rising, service users place more emphasis on non-functional attributes of services such as quality of service (QoS) and price during service selection. However, previous QoS-driven service selection methods seldom consider relationships among non-functional requirements and do not allow explicit specification of personalized preferences and...
Collaborative filtering is one of widely used Web service recommendation techniques. In QoS-based Web service recommendation, predicting missing QoS values of services is often required. There have been several methods of Web service recommendation based on collaborative filtering, but seldom have they considered locations of both users and services in predicting QoS values of Web services. Actually,...
Web services are very prevalent nowadays. Recommending Web services that users are interested in becomes an interesting and challenging research problem. In this paper, we present AWSR (Active Web Service Recommendation), an effective Web service recommendation system based on users' usage history to actively recommend Web services to users. AWSR extracts user's functional interests and QoS preferences...
