The shape and area of the crown of each tree are among the most influential parameters for identifying and controlling the processes of photosynthesis, respiration, transpiration and its management. In such a way that various physiographic functions, such as carbon dioxide absorption, light energy absorption, oxygen release and transpiration, which are vital for the growth and development of the tree, are done in the crown. In this research, the RGB image of the UAV with a spatial resolution of 2 cm was resampled to three pixel sizes of 10, 30 and 50 cm. Then, each image was classified separately by SVM, ANN and MLC algorithms, which are all part of Ensemble. In the next step, each of the obtained crowns was compared with the digitization of the same crown, and based on the area of the crown obtained from each classification and normalization method, the weight was obtained specifically for the same crown. Finally, by using the weighted majority voting method, classifications were fusioned at the decision level. The results showed that the ANN method gives better results in all pixel sizes compared to MLC and SVM. Also, the combination of different classification methods with the weighted majority voting method based on the weight assigned to the same crown based on each classification method has significantly increased the classification accuracy of the tree crown in all the sizes of the analyzed pixels. © Author(s) 2024.

Although Smart Grid (SG) transformation brings many advantages to electric utilities, the longstanding challenge for all them is to supply electricity at the lowest cost. In addition, currently, the electric utilities must comply with new expectations for their operations, and address new challenges such as energy efficiency regulations and guidelines, possibility of economic recessions, volatility of fuel prices, new user profiles and demands of regulators. In order to meet all these emerging economic and regulatory realities, the electric utilities operating SGs must be able to determine and meet load, implement new technologies that can effect energy sales and interact with their customers for their purchases of electricity. In this respect, load forecasting which has traditionally been done mostly at city or country level can address such issues vital to the electric utilities. In this paper, an artificial neural network based energy consumption forecasting system is proposed and the efficiency of the proposed system is shown with the results of a set of simulation studies. The proposed system can provide valuable inputs to smart grid applications.

Nowadays, many considerable efforts are focused on the development of efficient and effective systems that increase the productivity of vehicles by controlling and manipulating the extraordinary states, such as sliding and spinning, during the operational time. Those states play a central role in the performance of the vehicles described as an interaction among different mechanical parts regarding their life-time, their wear and tear, as well as the maintenance costs. In addition, these states ultimately affect the safety of target system and its environment. Therefore, the necessity of avoiding, controlling, or manipulating these states to lower their effects into a tolerable level has become the major driver for conducting the current research work. In this paper, a prototype for safety-related platform for detecting and controlling railway vehicles states by means of vibration capture is presented. Additionally, test procedures in order to collect the vibration data related to each state are presented; these tests were performed under the supervision of an industrial partner. Moreover, the recognized initial patterns of the vibration signals related to the studied states are also introduced.

In an interval graph G = (V,E) the distance between two vertices u, v is defined as the smallest number of edges in a path joining u and v. The eccentricity of a vertex v is the maximum among distances from all other vertices of V. The diameter (δ) and radius (ρ) of the graph G is respectively the maximum and minimum among all the eccentricities of G. The center of the graph G is the set C(G) of vertices with eccentricity ρ. In this context our aim is to establish the relation ρ = [δ/2] for an interval graph and to determine the center of it.

OMG's (Object Management Group) CORBA (Common Object Request Broker Architecture) is becoming a common platform for distributed computing environment. However, it is yet to address CSCW (computer Supported Collaborative Work) ftamework. This paper addresses the problem of building a framework for CSCW and proposes a new CSCW framework based on CORBA (CFC). CFC includes session, participant, mode, directory, stream, media and resource management. A desktop conference system and DSM-CC compliant video-on-demand system were built to demonstrate the usefulness of the framework. The performance of CORBA based CSCW applications is given. The strengths and weaknesses of using a CORBA framework are also discussed.

This paper presents linguistic primitives for publish/subscribe programming using events and objects. We integrate our primitives into a strongly typed object-oriented language through four mechnisms: (1) serialization, (2) multiple subtyping, (3)closures, and (4) deferred code evaluation. We illustrate our primitives through Java, showing how we have overcome its respective lacks. A precompiler transforms statements based on our publish/subscribe primitives into calls to specifically generated typed adapters, which resemble the typed stubs and skeletons by the rmic precompiler for remote method invocations in Java

The most critical task of a social network is to identify a central node. Numerous methods for determining centrality are documented in the literature. It contributes to online commerce by disseminating news, advertisements and other content via central nodes. Existing methods capture the node's direct reachability. This study introduces a novel method for quantifying centrality in a fuzzy environment. This measurement takes into account the reachability of nodes and their direct connections. Several critical properties have been demonstrated. A small Facebook network is used to illustrate the issue. Additionally, appropriate tables and graphs present a comparative study with existing methods for centrality measurement. © 2024-IOS Press. All rights reserved.

Lip reading is a technique that aims to understand spoken words by analyzing people's lip movements. Deep learning algorithms are used as a powerful tool for detecting and recognizing lip movements more accurately. In this study, we present a lip-reading architecture for the Turkish language. The architecture is trained to recognize Turkish words using 3DCNN (3D Convolutional Neural Network) architecture and two-stream deep learning methods. The model was trained on video data representing lip movements and learned to classify words accurately. The Turkish lip reading system has been trained and tested on a large Turkish lip reading dataset. In the experiments, an accuracy of 87.12% was achieved with the proposed model, indicating successful results in the Turkish language. The proposed model demonstrates high accuracy rates in recognizing Turkish words, showcasing its effectiveness. This paper introduces a novel architecture, a lip-reading system that employs deep learning techniques, providing a robust tool for successful Turkish lipreading applications. © 2023, The Authors.

Beyond Program Slicing 2005

作者： Kalleberg, Karl Trygve Hall, Tracy Ettinger, Ran Institutt for Informatikk Universitetet i Bergen PB 7800 NorwayN-5020 Norway Department of Computer Science Hertfordshire University HertfordshireAL10 9LB United Kingdom Programming Tools Group Computing Laboratory Oxford University OxfordOX1 3QD United Kingdom

By now, the concept of program slicing has been known in the research community for around 25 years. As a research topic, it has enjoyed a fair share of popularity, evidenced by the number of articles published on the topic following Mark Weiser’s seminal paper. However, outside research circles, program slicing appears to be virtually unknown. In this report, we take the premise that program slicing is both technically relevant, and has a sufficient theoretical foundation, to be applied in practice within the software industry. With this premise in mind, we ask ourselves, "what are the mechanisms by which we as a community could make program slicing mainstream"? © 2006 Dagstuhl Seminar Proceedings. All rights reserved.
