Fog computing is a promising architectural pattern to reduce the amount of data that is transferred to the cloud for processing and analysis. In this paper, we study fog-assisted data streaming scenario in which fog nodes at the network edge share their spare resources to help pre-process raw data of applications hosted in the cloud. A distributed resource sharing scheme is presented where the software...
To increase the spectral efficiency of wireless networks without requiring full-duplex capability of user devices, a potential solution is the recently proposed three-node full-duplex mode. To realize this potential, networks employing three-node full-duplex transmissions must deal with self-interference and user-to-user interference, which can be managed by frequency channel and power allocation...
We consider the beamforming design to maximize the energy-efficiency (EE) of a K link multiple-input multiple-output (MIMO) interference channel, where each link consists of two full-duplex (FD) nodes. We first transform the original fractional form optimization problem into an equivalent subtractive-form optimization problem by exploiting the properties of fractional programming, and then perform...
In this paper, we exploit the intrinsic relation between different adjective labels and develop a novel multilabel dictionary learning and sparse coding method which is improved by introducing the structured output association information. Such a method makes use of the label correlation information and is more suitable for the multi-label tactile understanding task. In addition, we develop a globally-convergent...
The objective of this work is to investigate gate oxide degradation in Lateral Double Diffused metal-oxide semiconductor (LDMOS) devices associated with Polysilicon Buffered Locos (PBL) isolation. It was found that the defects in the silicon at the edge of Polysilicon Buffered Locos resulting in severe degradation of charge-to-breakdown (Qbd) occurring at the edge of the active area silicon have been...
The fabrication process-induced variation in the yield strength of metal films in microelectronic devices critically impacts the reliability of inter-layer dielectric (ILD) stacks. However, estimation of the yield strength of buried films in multilayer stacks remains a significant challenge. The indentation technique, whose advantage is that it does not require a freestanding film, has been widely...
Structure and nonlocal patch similarity have been used successfully to enhance the performance of image restoration. However, these techniques can often remove textures and edges, or introduce artifacts. In this paper, we propose a novel image completion method that leverages the redundancy of nonlocal image patches via the low-rank regularization of similar patch groups. The textures and edges in...
Solving combinatorial optimization problems by reducing them to MaxSAT has shown to be a competitive problem solving approach. Since a lot of optimization problems have many-valued variables, we propose to exploit the domain information of the many-valued variables to enhance MaxSAT-based problem solving: first, we define a new way of encoding weighted maximum constraint satisfaction problems to both...
In this work, we investigate the routing and channel assignment problem in Self-Interference Suppression (SIS)-enabled CRNs, where FD communication is possible. Specifically, we propose a novel metric called “Path Capacity” that reflects the number of links that can be simultaneously activated across a given path while using the minimum possible spectrum resources. Accordingly, we develop a novel...
As more photovoltaic systems (PVs) are allocated to both transmission and distribution systems, it has been required to consider constraints of both transmission and distribution systems, such as power shortages and surpluses in transmission systems and voltages and current in distribution systems. This research proposes the framework to consider these constraints, and formulates the optimal allocation...
We study a single location supply system for repairable spare parts. The system consists of a multi-server repairshop and inventory of ready-to-use spare parts. When a failed part is received, a new (or as-good-as-new) replacement (if on stock) is sent back, and the failed part is queued for repair. In the case of unavailability, the failure requests are fulfilled when a ready-for-use part is received...
This paper formulates a bi-criteria fuzzy blocking flow shop scheduling problem with fuzzy processing time and fuzzy due date. An improved multi-objective grey wolf optimization (MOGWO) algorithm is proposed to solve this combinational optimization problem. The proposed MOGWO utilizes the ranked-order-value (ROV) rule for solution representation, employs a dynamic maintenance strategy to maintain...
In many scenarios of interest, agents may only have access to partial information about an unknown model or target vector. Each agent may be sensing only a subset of the entries of a global target vector, and the number of these entries can be different across the agents. If each of the agents were to solve an inference task independently of the other agents, then they would not benefit from neighboring...
Tool-to-tool matching of optical proximity effect (OPE) properties is required and the procedure is called OPE matching. Nikon has developed a software called OPE Master for the purpose, which can decrease OPE errors with emphasis placed on critical dimension (CD) errors by optimizing exposure tool's parameters, such as lens numerical aperture (LNA), pupilgram intensity distribution, pupilgram distortion...
The pattern synthesis technique described here is unique in that it allows the power pattern to be optimized in a very useful sense over the desired operating band of the array. This is an improvement over previous techniques involving constraints on such artificial parameters as source norm and superdirectivity ratio which do not in fact ensure a useful pattern bandwidth. The procedure described...
Automatic Speaker Verification is the authentication of a claimed identity based on characteristics of voice. A speaker verification system compares a person's voice with a speaker model or stored voiceprint captured during enrollment as well as an imposter model of different voices, genders and phone types. The system then assigns a confidence score and then makes a decision whether to let the person...
We study a single location supply system for repairable spare parts. The system consists of a multi-server repair shop and inventory with ready-to-use spare parts. When a failed part is received, a new (or as-good-as-new) replacement part is sent back, and the failed part is forwarded to the repairshop. In the case of unavailability of spare parts, failed requests are backordered and fulfilled when...
System-level thermal management techniques normally map applications on non-adjacent cores to guarantee the safe temperature in many-core systems, while the communication efficiency will be oppositely affected by long-distance data transmission over conventional Network-on-Chips (NoC). SMART NoC has enabled single-cycle multi-hop bypass channels between distant cores, which can significantly reduce...
ARM's big. LITTLE architecture coupled with Heterogeneous Multi-Processing (HMP) has enabled energy-efficient solutions in the dark silicon era. System-level techniques activate nonadjacent cores to eliminate chip thermal hotspot. However, it unexpectedly increases communication delay due to longer distance in network architectures, and in turn degrades application performance and system energy efficiency...
Due to the non-linearity of current-voltage of solar cell model, the conventional methods are incapable to extract the parameters of solar cell with high accuracy. The implicit nonlinear equation describing the single and double diodes solar cell in five and seven parameters is rewritten as optimization problems with constraint functions and it is solved by using a firefly algorithm optimization....
