The notion of a Private Information Retrieval (PIR) code was recently introduced by Fazeli, Vardy and Yaakobi [1] who showed that this class of codes permit PIR at reduced levels of storage overhead in comparison with rephcated-server PIR. In the present paper, the construction of an (n, k) τ-server binary linear PIR code having parameters n = ℓΣi=0(mi), k = (mi) and τ = 2ℓ for any integer m ≥ ℓ ≥...
In this paper, a novel resolution enhancement approach based on Quaternion wavelet transform (QWT) with singular value decomposition (SVD) is proposed. The technique decomposes the input image into sixteen frequency sub bands by using QWT. The singular values of the low-low sub band image are estimated and the high frequency sub bands are interpolated using Lanczos interpolation. Finally, a contrast...
In this paper, the algorithm of I-PD controller is implemented on a microcontroller (Arduino / freeeduino (ATmega 328)) to control the temperature and pressure of a system, since temperature pressure and volume are the three important parameters of any system, by controlling any two of this parameters the third parameter will be automatically controlled, because these three parameters are interdependent...
In recent days, camera manufacturers continue to pack increasing numbers of pixels per unit area, an increase in noise sensitivity manifests itself in the form of noisier image. Camera manufacturers, therefore, depend on image denoising algorithms to reduce the effects of such noise artifacts in the resultant image. The most common type of noise is impulse noise, in which the affected pixels are replaced...
Identification of root causes of a performance problem is very difficult in case of large scale IT environment. A model which is scalable and reasonably accurate is required for such complex scenarios. This paper proposes a hybrid model using random forest and statistical change point detection, for root cause localization. Based on impurity measure and change in error rates, random forest identifies...
We describe our work on pronominal resolution in Tamil using Tree CRFs. Pronominal resolution is the task of identifying the referent of a pronominal. In this work we have studied third person pronouns in Tamil such as 'avan', 'aval', 'athu', 'avar', he, she, it and they respectively. Tamil is a Dravidian language and it is morphologically rich and highly agglutinative language. Tree CRFs is a machine...
Low power testing in VLSI has emerged as a standard idea in today's electronics industry. The need for low power is root for a major pattern shift where power consumption has become a significant concern while comparing with performance and area. This work explores XOR network with Linear Feedback Shift Register (LFSR), which is having different tap connection. The proposed work is associated with...
The design for low power has become one of the greatest challenges in high-performance very large scale integration (VLSI) design. It has been found that the power consumed during test mode operation is often much higher than during normal mode operation. This is because most of the consumed power results from the switching activity in the nodes of the circuit under test (CUT), BIST technique uses...
Over the past decade, quantum coherent behavior has been observed in electrical circuits engineered to have discrete, individually addressable energy levels. These devices operate at cryogenic temperatures and microwave frequencies—conditions which permit the utilization of superconducting passive and active resonant circuits for measurement. The basic architecture of a quantum dispersive measurement...
Transfer Grammar is an integral component of a Rule based Machine Translation system. In this paper, we describe a subset of the transfer grammar developed for Tamil to Hindi Machine Translation system, i.e., the transfer of nominal constructions from Tamil to Hindi. Nominal constructions in Tamil, which is an agglutinative language, take multiple suffixes which may be case markers or other suffixes...
The paper deals with the transfer of finite verb structure from Tamil to Hindi using a rule-based approach in a machine translation system. This task is challenging as it involves the transfer of more grammatical information apart from lexical transfer and also because of the highly inflectional nature of finite verb morphology in Tamil compared to Hindi.
A software defined radio (SDR) is a device in which the functionality can be altered with the help of software. Hence defining the difference in behavior for various technologies in software, removes the need for hardware alterations during a technology upgrade. The role of modulation techniques in an SDR is very crucial since modulation techniques define the core part for any wireless technology...
This paper presents a preemption control based bandwidth preserving server approach to improve the quality of service in terms of better responsiveness to the aperiodic task and reduce their rejection ratio while ensuring the feasibility of periodic task at the same time. Feasibility analysis is done at offline by assigning the priority of periodic tasks as well as server to service the aperiodic...
End-to-end latency of messages is an important design parameter that needs to be within specified bounds for the correct functioning of distributed real-time control systems. In this paper we give a formal definition of end-to-end latency, and use this as the basis for checking whether a stipulated deadline is violated within a bounded time. For unbounded verification, we model the system as a set...
