Digital LCR meter using arduino

Abstract: Measurement of electrical parameters such as Inductance (L), Capacitance (C) and Resistance (R)plays an integral role in the real world implementation of the circuits. This paper is focused on design and development of a LCR meter using simple techniques that leads a low cost device at the beginner level. The techniques are implemented on TINA software along with the hardware implementations using Arduino UNO. Results obtained from developed device are confirmed with commercial LCR meter.

Agent-Based Adaptive Bandwidth Allocation in Wireless Networks

Abstract: Services provided over wireless networks are growing at a rapid pace with the increasing number of users and their demands. Some of the services demand real-time multimedia communication and stringent bandwidth requirements owing to their varied service characteristics. Thus, there is a requirement for developing efficient bandwidth allocation schemes to achieve acceptable Quality of Service (QoS) and meet these challenges. Bandwidth is the most critical resource in wireless networks, which should be managed efficiently. This paper proposes an agent based adaptive bandwidth allocation scheme that allocates the bandwidth by using an interference bandwidth allocation algorithm in cellular system. Proposed scheme claims an agent based bandwidth allocation delay of 24.5 microseconds as opposed to 78 microseconds with non-agent based approach.

Synthesis and biological evaluation of 3-[p-(heterocyclocarbonyl)]phenylsydnones from the versatile precursor, 3-[p-(hydrazinocarbonyl)]phenylsydnone

Abstract: The synthetic versatility of 3-[p-(hydrazinocarbonyl)]phenylsydnone is demonstrated in the syntheses of various heterocyclic compounds. For example, pyrazoles, fused pyranopyrazoles, 1,3,4-thiadiazoles, 1,3,4-oxadiazoles and 1,2,4-triazoles can be built on the phenyl ring of this 3-phenyl sydnone. The phenylsydnones prepared herein were characterized spectroscopically and subjected to antibacterial and antifungal screening. The compounds demonstrated high fungicidal activities. 3-[p-(hydrazinocarbonyl)]phenylsydnone has proven to be a versatile precursor for the synthesis of various related derivatives and may be used further in preparing various pharmaceutical and agricultural compounds.

Kannada Speech Recognition Using Decision Tree Based Clustering

Abstract: This paper presents the recognition of Kannada language by employing decision tree based clustering to build context dependent triphone HMMs. Language-specific knowledge is required to generate phonetic questions required for clustering triphones. The success of clustering depends mainly on correctly identifying the parameters that are correlated and are grouped. By using phonetic table of the target language and universal list of articulatory questions, language specific articulatory question list is created which can then be used to cluster triphones. This method of triphone clustering requires least human intervention. Perplexity is also measured for the database of Kannada language and the database having lower perplexity is used for testing performance of the generated triphones. It is observed that, triphones which are clustered using universal list of articulatory questions performs well compared with manually created phonetic question list.
