A Proposal to Adjust the Time-Keeping Systems for Savings in Cycling Operation and Carbon Emission

Abstract: With the spread of the power transmission networks to thousands of kilometres, the integrated power grid in many countries cover multiple hours in terms of solar position. We present a general mathematical model with multiple time-keeping systems for flattening the electrical load curve in a territory having integrated power grid operations. The multiple time-keeping system areas are set up as a function of both electrical power demand and mean geographical position in longitude. Fluctuation in load results in cycling operation of coal/gas power plants and enhanced carbon emission. In this paper, an attempt is made to quantify the savings in cycling of electrical power plant operation and the associated carbon emission with adjustment of time-keeping systems. For the territory of India, the reduction in cycling operation of power plants by 9% of peak demand is demonstrated.

Word Estimation in Continuous Colloquial Bengali Speech

Abstract: Word segmentation is a crucial part in any speech to text conversion. Many works have been done on popular languages, especially on English, but a very few work has been carried out on Bengali language, especially on colloquial speech. In our work, we present a simple pitch profile-based technique to find the words in a Bengali speech. We extract the feature of the existence of words based on the pitch profile of a speech. To find the pitch profile, we have used the state phase technique. A simple deviation of a 20 ms window is studied to find the pitch. In order to reshape the pitch, power profile of the speech is used. Then apply morphology to make the profile more robust. Finally, we cluster the data and use silhouette index to select the number clusters present in the data which in turn estimate the word boundaries. The algorithm is tested over continuous colloquial Bengali speech.

Borromean states of exotic systems under screened coulomb interactions

Abstract: Benchmark calculations on the Borromean window have been done for a number of thee-body exotic muonic, pionic and Kaonic systems under screened Coulomb interactions.

Detection of Black Hole Attack in Delay-Tolerant Network

Abstract: In spite of modernization of humanity, in emergency situations like after any natural calamity our infrastructure-based network backbone gets affected first. Disaster relief volunteers face the immense pain to set up a communication system, due to the failure of telecommunication infrastructure and long-standing power. Smartphones are the most preferable devices, operating and acting in delay-tolerant mode through Bluetooth/Wi-Fi, for setting up a peer-to-peer network enabling communication in post-disaster network. It is now popularly known as delay-/disruption-tolerant network (DTN). In this network, a node can misbehave and fail to establish a route or direct the data to neighbor node due to its malicious activity to decrease the performance of overall network. If a node suddenly drops messages after receiving, then it is known as black hole node. Black hole nodes do not forward any messages and can also destroy the message forever. A node may also act as a partially black hole node with the character of selective dropping. However, black hole nodes can hamper the overall performance of the network. In this paper, we have proposed a method to detect and avoid the malicious nodes forming black hole attack in DTN. We also evaluate the scheme using ONE simulator.

Enhanced FSR Asymmetrical Triple Optical Ring Resonator

Abstract: The paper proposes an Asymmetrical Triple Optical Ring Resonator (ATORR) and investigates its performances. Delay line signal processing scheme along with Mason’s Gain Formula is implemented to develop the transfer function of this configuration. Two different materials are used for this model, i.e., SOI (2.0167) and SIN (2.811), and their frequency responses are analyzed and compared to obtain different Free Spectral Range (FSR) outputs on MATLAB. Along with widening of FSR, crosstalks and resonance loss are also reduced. The extended FSR output is in THz range that has wide application in the field of photonics.
