Tool Support of Developing Systems Simulation with Active Elements
Get PDFA new approach to the simulation of developing systems is proposed and discussed It is based on the idea on independent development of the so-called aspect models whose interconnection is provided by tool computational environment The main features of the approach are the abandonment of postulate of the deterministic behavior of systems if they are developed due to activity of elements and orientation parallel simulation event-driven elements behavior We discuss their initial requirements of the tool suppor
Multimodal Attention in Recurrent Neural Networks for Visual Question Answering
Get PDFVisual Question Answering (VQA) is a task for evaluating image scene understanding abilities and shortcomings and also measuring machine intelligence in the visual domain. Given an image and a natural question about the image, the system must ground the question into
Citrus Fruit Feature Extraction using Colpromatix Color Code Model
Get PDFClassification of citrus fruit more precisely and economically under natural illumination circumstances. The aim of this paper was to develop a robust and feature extraction techniques to discover citrus fruit features with different dimensions and under different illumination conditions. To identify object residing in image, the image has to be described or represented by certain features. In this paper, proposed a citrus fruit feature extraction process for deriving the classification. The proposed system present two tasks namely, 1) Image pre-processing: it is carried out using Hybrid Noise filter to remove the noise; ii) Citrus fruit features extraction: Feature extraction using new Colpromatix color space model, Size, Texture, Shape, and Coarseness. The Image Shape is an important visual feature of an image. Difference features representation and description techniques are discuss in this review paper. Feature extraction techniques play an important role in systems for object recognition, matching, extracting, and analysis. It also presents comparison between various techniques
MANET
Get PDFMANET is used to provide communication among the nodes. There is no central authority which control communication session between nodes i.e. there is no any defined infrastructure. Nodes moves frequently in the network which generate some issues like routing, coverage, congestion and security issues. Quality of service (QoS) in MANET is universally a growing area. Here, different mobile devices collaborate to form a communication network without any pre- existing infrastructure. Due to vast expansion of multimedia technology, mobile technology and real time applications has need to strictly support quality of service such as throughput, delay, energy consumption, jitter etc. This paper presents the description about the message sending in MANET and its QoS
Some NP-Hard Problems for the Simultaneous Coprimeness of Values of Linear Polynomials
Get PDFThe algorithmic-time complexity of some problems connected with linear polynomials and coprimeness relation on natural numbers is under consideration in the paper. We regard two easily stated problems. The first one is on the consistency in natural numbers from the interval of a linear coprimeness system. This problem is proved to be NP-complete. The second one is on the consistency in natural numbers of a linear coprimeness and discoprimeness system for polynomials with not greater than one non-zero coefficient. This problem is proved to be NP-hard. Then the complexity of some existential theories of natural numbers with coprimeness is considered. These theories are in some sense intermediate between the existential Presburger arithmetic and the existential Presburger arithmetic with divisibility. In a form of corollaries from the theorems of the second section we prove NP-hardness of the decision problem for the existential theories of natural numbers for coprimeness with addition and for coprimeness with successor function. In the conclusion section we give some remarks on the NP membership of the latter problem
Thai to Khmer Rule-Based Machine Translation Using Reordering Word to Phrase
Get PDFIn this paper an effective machine translation system from Thai to Khmer language on a website is proposed To create a web application for a high performance Thai- Khmer machine translation ThKh-MT the principles and methods of translation involve with lexical base Word reordering is applied by considering the previous word the next word and subject-verb agreement The word adjustment is also required to attain acceptable outputs Additional steps related to structure patterns are added in a combination with the classical methods to deal with translation issues PHP is implemented to build the application with MySQL as a tool to create lexical databases For testing 5 100 phrases and sentences are selected to evaluate the system The result shows 89 25 percent of accuracy and 0 84 for F-Measure which infers to a higher efficiency than that of Google and other system
Scheduling Techniques for Operating Systems for Medical and IoT Devices: A Review
Get PDFSoftware and Hardware synthesis are the major subtasks in the implementation of hardware/software systems. Increasing trend is to build SoCs/NoC/Embedded System for Implantable Medical Devices (IMD) and Internet of Things (IoT) devices, which includes multiple Microprocessors and Signal Processors, allowing designing complex hardware and software systems, yet flexible with respect to the delivered performance and executed application. An important technique, which affect the macroscopic system implementation characteristics is the scheduling of hardware operations, program instructions and software processes. This paper presents a survey of the various scheduling strategies in process scheduling. Process Scheduling has to take into account the real-time constraints. Processes are characterized by their timing constraints, periodicity, precedence and data dependency, pre-emptivity, priority etc. The affect of these characteristics on scheduling decisions has been described in this paper
The Components that can Build Flexible
Get PDFSDN (Software Defined Network) is a new networking approach towards current networking industry. S.D.N has attarcted the researchers attention, because there is wide scope of innovation and research. The main concept behind the SDN networks is the separation of controller from data plane. This natural feature makes SDN adaptive of being flexible and scalable. We are mentioning some of the important components those are needed to make current SDN networks even better and efficient that can be managed easily and updated whenever needed, without any interruption of services. Also we have discussed how we can manage the data plane, control plane and how we can identify where fault has occurred
Application and Performance Analysis of DSDV Routing Protocol in ad-hoc Wireless Sensor Network with Help of NS2 Knowledge
Get PDFWireless Sensor Networks (WSNs) are characterized by multi-hop wireless connectivity, frequently changing network topology and need for efficient routing protocols. The purpose of this paper is to evaluate performance of routing protocol DSDV in wireless sensor network (WSN) scales regarding the End-to-End delay and throughput PDR with mobility factor .Routing protocols are a critical aspect to performance in mobile wireless networks and play crucial role in determining network performance in terms of packet delivery fraction, end-to-end delay and packet loss. Destination-sequenced distance vector (DSDV) protocol is a proactive protocol depending on routing tables which are maintained at each node. The routing protocol should detect and maintain optimal route(s) between source and destination nodes. In this paper, we present application of DSDV in WSN as extend to our pervious study to the design and implementation the details of the DSDV routing protocol in MANET using the ns-2 network simulator. also, the performance of DSDV protocol in sensor network of randomly distributed mobile nodes with mobile source and sink nodes is investigated for MAC IEEE802.15.4 network by ns-2 simulator.
