Most existing concepts for hardware implementation of reversible computing invoke an adiabatic computing paradigm, in which individual degrees of freedom (e.g., node voltages) are synchronously transformed under the influence of externally- supplied driving signals. But distributing these "power/clock" signals to all gates within a design while efficiently recovering their energy is difficult...
We define some of the programming and system-level challenges facing the application of quantum processing to high-performance computing. Alongside barriers to physical integration, prominent differences in the execution of quantum and conventional programs challenges the intersection of these computational models. Following a brief overview of the state of the art, we discuss recent advances in programming...
In the near future, one of the main processes is solving large combinatorial optimization problems. However, the performance growth of von Neumann architecture will slow due to the end of semiconductor scaling. To resolve this problem, we propose an Ising computer that maps the optimization problems to the ground state search of Ising models. We previously proposed a computer that finds the ground...
Computer Network has great effect on improving the efficiency of the communication system and application requirements in our life. In order to establish transmission path with movement characteristics and improve the efficiency of information transmission in Computer Network, the optimized clustering routing protocol based on node position using the minimum distance routing competition mechanism...
It is difficult for managers to do real-time traffic estimation under urban road network because of the incompletion of information collection and the complexity of road network. This paper will improve the precision of data expansion algorithm presented by Lederman R and Wynter L. (2011) using Kalman Filter during real-time estimation. Computation is composed of a heavyweight offline calibration...
Currently, literature points out the lack of studies about collaborative virtual environments with intelligent tools capable of providing automatic evaluation feedback of different collaborative procedures (e.g., surgical, military training). In addition, there is a lack of classifications and methodologies for the implementation of CVEs with simultaneous evaluation of multiple users, making it difficult...
We have witnessed the exponential growth of 3D GIS applications which vary from 3D urban management, a heritage city, archaeology, flood controlling, planning and designing, and government planning, to name a few. Thanks to the diversity of 3D models that are used to represent objects in reality and spatial database systems that are utilized to store spatial data, designers and developers can explore...
Hardware-in-the-Loop Simulation is being increasingly used in verification and validation of embedded computer systems; as well as for rapid prototyping and validation of models. The numerous benefits of this technique and the possibility of widespread use is hindered by the high cost of the necessary infrastructure. The proposed solution is based on a PC executing the plant simulation and connected,...
In this paper, we review the main middleware re-quirements applied to Internet of Things and High-Performance Computing combined, here called IoT/HPC. The goal was to describe a unique set of requirements that middleware systems should attempt to guarantee the development of integrated applications. Among many core complex services, the IoT/HPC challenges are related to the support of sensing, actuating,...
Model based tracking techniques allow computing the pose of 3d objects without needing to use markers. In order to perform a precise tracking, these techniques have been using RGB-D sensors together with particle filters for evaluating several pose hypotheses of the object in a given frame from features such as points 3D coordinates, color and normal vector. This work presents a proposal to use of...
Extending from limited domain to a new domain is crucial for Natural Language Generation in Dialogue, especially when there are sufficient annotated data in the source domain, but there is little labeled data in the target domain. This paper studies the performance and domain adaptation of two different Neural Network Language Generators in Spoken Dialogue Systems: a gating-based Recurrent Neural...
We present a model-based testing approach for reactive systems where both test inputs and expected results are generated from ‘restricted’ Event-B specifications. We show that it is possible to automatically build the restricted Event-B specifications from the original ones base on a knowledge base of the system under tests. The restricted models are to reduce the state space of the original Event-B...
Histogram of Oriented Gradient (HOG) is a popular feature description for the purpose of object detection. However, HOG algorithm requires a high performance system because of its complex operation set. In HOG algorithm, the cell histogram generation is one of the most complex part, it uses inverse tangent, square, square root, floating point multiplication. In this paper, we propose an accurate and...
Model-based software estimation uses algorithms and past project data to make predictions for new projects. This paper presents a comparative assessment of four modeling approaches, including the original COCOMO, COCOMO calibration, k-Nearest Neighbors, and a combination of COCOMO calibration and k-Nearest Neighbors. Our results indicate that using kNN to select the nearest projects and calibrating...
This work investigates the anonymous tag cardinality estimation problem in radio frequency identification systems with frame slotted aloha-based protocol. Each tag, instead of sending its identity upon receiving the reader's request, randomly responds by only one bit in one of the time slots of the frame due to privacy and security. As a result, each slot with no response is observed as in an empty...
Complex power equipment has the characteristics of complex structure, involving a wide range of knowledge, many disciplines, difficult in system simulation, many of the equipment is running in high temperature, high pressure, high voltage and other extreme and dangerous environment, the real experiment has high risk, high energy consumption, high cost and can not carry out, not all the related professional...

Based on massive amounts of data distribution, this model completed the data backup protocol based on master copy of distributed design and the Paxos distributed system protocol design on the basis of the...
This paper formulates and studies the problem of distributed filtering based on randomized gossip strategy in order to estimate the state of a dynamic system via all sensors in a network. First we introduce the randomized gossip algorithm by which the fastest averaging strategy can be obtained for a network with an arbitrary topology. Then we combine the randomized gossip algorithm with the information...
The IEEE Computer Society's Guide to the Software Engineering Body of Knowledge (SWEBoK) has been an authoritative basis for software engineering since 2004. It also has served as a foundation for other developments including curriculum development, training, software engineering competence definitions, and licensing and certification. SWEBoK is current being updated through the SWEBoK Evolution effort...
