In the field of machine translation ample amount of work has been done to improve the essence of translation systems. It all started in 1949 when Warren Weaver proposed the first idea of using computer for translation. Since then several approaches have been followed out to ameliorate the quality of translation. But even after continuing development in this field, we haven't reached the level where...
Recently, short message service (SMS) has become one of the most popular applications for mobile users. However, it provides convenience for worms to spread in mobile networks. Due to the differences between computers and smartphones, the current propagation models of computer worms cannot be employed in the mobile network directly, especially in the SMS scenario. In this paper, we propose a worm...
In this paper, we use the Kirchhoff equations to model of the dynamics of underwater rigid-bodies under some assumptions on the surrounding fluid. The Kirchhoff tensor, which totally characterizes the interaction of the rigid-body with the fluid is assumed to be unknown. We then propose a control law with an estimate of the Kirchhoff tensor and a corresponding update law for the estimate to track...
In this work, multiple time-scale estimates of auditory features have been introduced to capture the effect of short time-transients additive noise present over some specific active regions in a speech utterance and these multiple time-scale auditory features have been used for non-intrusive speech quality measurement. The use of single time-scale auditory features is not accurate in capturing the...
Lyon's auditory features and Multi-Resolution Auditory Model (MRAM) features for narrowband speech sampled at 8 kHz for different degradations are computed. The Gaussian Mixture Model (GMM) has been used to map these auditory features of narrowband speech into the objective mean opinion score (MOS) using Expectation Maximization (EM) algorithm. Non-intrusive speech quality assessment has been done...
Today, cloud computing serves as a request response model, where a client makes request for various available services on “pay as you go basis”. Cloud computing offers a dynamic flexible resource allocation phenomenon. For reliable and guaranteed services there must be a scheduling mechanism that all resources are efficiently allocated to satisfy the customer's request. Cloud services are based on...
In this paper we describe a method of morphologically segment highly agglutinating and inflectional languages from the Dravidian family. We use the nested Pitman-Yor process to segment long agglutinated words into their basic components, and use a corpus based morpheme induction algorithm to perform morpheme segmentation. We test our method on two languages, Malayalam and Kannada and compare the results...
A hospital in Singapore considers deploying radio-frequency identification (RFID) system and setting up a new discharge lounge to improve the patient discharge process. This study uses computer simulation in modeling and comparing the current process without the RFID system and the discharge lounge and the new process with the RFID system and the discharge lounge, and assesses the impact of the RFID...
The principle objective of this paper is to develop a cloud based model, which is highly distributed with the inherent features like ease of use, reliability, dynamic scalability and low cost. Since adoption of various IT technologies are their implementation for various sectors is exponentially growing, an attempt has been made to address power system problems in cloud environment. To validate, one...
Services Computing has turned into the mainstream programming paradigm for building enterprise systems that are distributed in nature. However, the programming power available to the developers of service oriented systems has been slow to catch up. The object abstraction continues to be the prevalent mechanism for implementing services based software systems and has several drawbacks. A key drawback...
Constraints, specifically Separation of Duty (SoD) constraints, constitute an essential component for specifying Role Based Access Control (RBAC) policies. While it has been shown earlier that SoD constraints can be effectively represented using a set of t - t Statically Mutually Exclusive Roles (SMER) constraints, this paper presents a method for finding minimum number of users under multiple SMER...
Performance estimation of an application on any processor is becoming a essential task, specially when the processor is used for high performance computing. Our work here presents a model to estimate performance of various applications on a modern GPU. Recently, GPUs are getting popular in the area of high performance computing along with original application domain of graphics. We have chosen FERMI...
In this paper, we propose a decentralized parallel computation model for global optimization using interval analysis. The model is adaptive to any number of processors and there is no need to design an initial decomposition scheme to feed each processor at the beginning. The work load is distributed evenly among all processors by alternative message passing. Numerical experiments indicate that the...
