Robust Smart Grid Monitoring Network Based on Direct Sequence Spread Spectrum Intelligence

Abstract: The ascendance of the smart grid concept has provided high hopes of developing an intelligent network that is capable of being a self-healing grid and ability to overcome the interruption problems. We developed a MATLAB-based system to examine the effect of jamming for smart grid applications in improving the reliability of the smart grids via MCS approach to model physical CTSF 34- node. The objective is to measure jamming effects on the dependability indices, BER through direct spread spectrum. This paper also analyses the effects of varying the jammer bandwidth for the CTSF node smart feeder (mode 1) and its Markov model (mode 2) with DSSS simulated BER results in less than 0.5 approximately and robust for random variation in jamming signal.

Enabling Collaborative Technologies for Effective E‐Learning within and Outside Class Rooms

Abstract: We emphasize on the various state of the art tools and leveraging technologies on‐line and offline the conventional e‐classrooms. In this paper, various ways within which latest technologies can be utilized for collaborative learning, content development, creation of knowledge resource contents, structuring of syllabi for universities, learning beyond the class room, introducing innovative methodologies in teaching are discussed.Providing proper connect routes for evaluation processes is equally important for proper effective student assessment. One should ensure that during collaborative learning there exist a proper mobile connectivity in the e‐classrooms having physical presence of learners and should be structured and oriented specifically in a secured mode of the teacher/presenter. During off‐line and on‐line evaluation interactions, proper LAN and mobile connectivity is to be ensured and necessary protocols have to be set. E‐discipline is highly critical from the point view of generation of total non‐ interference ambience (or negligibly low noise level) in the online class room. E‐instruction collaborative classrooms are ideal for effective self assessments and collaborative content generation options for launching interactive lessons anywhere in the classrooms can be thought about. The instant feedback to the teacher on content up‐gradation is to be accommodated in view of development of healthy e‐contents. This facilitates on‐line updation /adjusting instructions instantly. Closed loop communicative teaching can go with a matured e‐instruction content development provided a set of teacher facilitator team out of the learners is rightly chosen. In this paper some of the concepts relevant to the underlying principles of collaborative teaching on‐line and off‐line have been highlighted. A few case studies for faster, effective, interactive, enabling and leveraging technology is also presented in this work.

32-bit Signed and Unsigned Advanced Modified Booth Multiplication using Radix-4 Encoding Algorithm

Abstract: This paper presents the design and implementation of Modified Booth encoding multiplier for both signed and unsigned 32 bit numbers multiplication. The already existed Modified Booth Encoding multiplier and the BaughWooley multiplier perform multiplication operation on signed numbers only. Whereas the array multiplier and Braun array multipliers perform multiplication operation on unsigned numbers only. Thus, the requirement of the modern computer system is a dedicated and very high speed unique multiplier unit for signed and unsigned numbers. Therefore, this paper presents the design and implementation of Booth multiplier. The modified Booth Encoder circuit generates half the partial products in parallel. By extending sign bit of the operands and generating an additional partial product the SUMBE multiplier is obtained. The Carry Save Adder (CSA) tree and the final Carry Look ahead (CLA) adder used to speed up the multiplier operation. Since signed and unsigned multiplication operation is performed by the same multiplier unit the required hardware and the chip area reduces and this in turn reduces power dissipation and cost of a system.

A Comparative Analysis of Circular and Hexagonal Split Ring Resonator for Reduction of Mutual Coupling Effect

Abstract: A comparative analysis of circular shaped split ring resonators (CSRR), hexagonal shaped split ring resonators (HSRR) and their incorporation with 1x2 microstrip patch antenna array to suppress the effect of mutual coupling is proposed in this paper. By incorporating CSRR and HSRR metamaterial structure near the right side of the conventional radiating patch antenna array with resonating frequency of 2.4 GHz, the isolation of 12.17 dB and 13.88 dB is achieved respectively without altering the resonating frequency and radiation characteristics. The performance of the suggested antenna array with CSRR and HSRR has been assessed using HFSS simulator and may be used for ISM band application.
