ENERGY EFFICIENT DESIGN IN COGNITIVE RADIO NETWORKS WITH DELAY BOUNDS

Energy Efficiency is one of the crucial parameters in the design of modern wireless and other futuristic communication systems. Cognitive Radio is a highly evolving physical layer technology which is known for its environment-aware operations, self-configurability and learning. Energy Efficient design is inevitably a matter of addressing various trade-offs. In this paper, we formulate an optimization frame work for maximizing the energy efficiency by jointly optimizing the sensing duration and transmission duration. Also, the delay bounds are carefully designed in such a way that they are not beyond the desired values. Numerical and simulation results indicate that the proposed methodology resulted in higher energy efficiency compared to many existing methods. Apart from boosting up the achievable energy efficiency, this work was successful in bringing the delay bounds with in the desired range
Energy Balance in AC Is-landed Micro-grid by Frequency Bus Signaling Method

To keep the frequency stable and maintain overall stability of the AC Is-landed micro-grid, power exchange among DGs, ESS, and loads should be balanced. Many innovative control techniques have been proposed and used for enhancing the stability of micro-grid for proper energy balance. In this work, a self-Governing autonomous power control strategy based on Frequency Bus signaling is proposed in order to achieve power management. The main objective of this proposed strategy is to control the state of charge of Battery reservoir limiting the voltage on its terminals by controlling the power generated by the Renewable energy sources. The electrical frequency of the micro-grid is used to inform the power sources and their respective converters the amount of power they need to generate in order to maintain the ESS state of charge below or equal its maximum allowable limit. This method uses only local measurements for power distribution. Main power management function is implemented locally in primary level, while bounded frequency control can be achieved by using additional controller system.
Hammouda IM, Beyari MM (2015) Light Emitting Diode in Comparison to Halogen Curing Technology: Microshear Bond Strength of Dental Composite Resin Re- storative

In the last few years, curing light technology has advanced with the introductions of high intensity halogen lights, light emitting diode lights(LED) and plasma arc lights for resin composite polymerization [1-3]. Despite their popularity, halogen technology light curing units (LCUs) have several drawbacks. For example, halogen bulbs have a limited effective lifetime of approximately 40–100 h [4,5]. In addition, the halogen LCU’s bulb, reflector and filter degrade over time due to the high operating temperatures and the large quantity of heat which is produced during the duty cycles. This result in a reduction of the halogen LCU’s curing effectiveness over time [4].

Search Engine For Ebook Portal

: The purpose of this paper is to establish the textual analytics involved in developing a search engine for an ebook portal. We have extracted our dataset from Project Gutenberg using a robot harvester. Textual Analytics is used for efficient search retrieval. The entire dataset is represented using Vector Space Model, where each document is a vector in the vector space. Further, for computational purposes we represent our dataset in the form of a Term Frequency-Inverse Document Frequency (tf-idf) matrix. The first step involves obtaining the most coherent sequence of words of the search query entered. The entered query is processed using Front End algorithms this includes-Spell Checker, Text Segmentation and Language Modeling. Back End processing includes Similarity Modeling, Clustering, Indexing and Retrieval. The relationship between documents and words is established using cosine similarity measured between the documents and words in Vector Space. Clustering performed is used to suggest books that are similar to the search query entered by the user. Lastly, the Lucene Based Elasticsearch engine is used for indexing on the documents. This allows faster retrieval of data. Elasticsearch returns a dictionary and creates a tf-idf matrix. The processed query is compared with the dictionary obtained and tf-idf matrix is used to calculate the score for each match to give most relevant result.
Energy Efficient Wireless Sensors in One Dimensional Networks

Wireless Sensor Networks offers a wide range of applications in areas such as traffic monitoring, medical care, inhospitable terrain, robotic exploration and agriculture surveillance. In wsn, thousands of physically embedded sensor nodes are distributed in possibly harsh terrain and in most applications, it is impossible to replenish energy via replacing batteries. In order to cooperatively monitor physical or environmental conditions. The main task of sensor nodes is to collect and transmit data. It is well known that transmitting data consumes much more energy than collecting data. The advent of efficient wireless communications and advancement in electronics has enabled the development of low-power, low-cost and multifunctional wireless sensor nodes that are characterized by miniaturization and integration. The main aim of this project is to effectively send the data (value added and original) using opportunistic routing algorithm and to improve energy efficiency in one dimensional network. Here we send the data to sink using one dimensional networks, so it cannot divert to other nodes. It will go directly to sink. Another process of route finding depends on its coverage. In this process effectively transfer the emergency data to the sink.
Performance analysis of MIMO-OFDM formultiple antennas

Multiple Input Multiple Output (MIMO) uses multiple antennas at both the transmitter and receiver side. In recent times the demand for the use of MIMO systems has increased due to its capability of robustness against Multipath fading and increase in the Spatial Multiplexing Gain and Spatial Diversity Gain. Orthogonal Frequency Division Multiplexing (OFDM) is one of the best digital modulation schemes, where signal is divided into number of narrow band channels to obtain spectral efficiency and minimizing the Inter Symbol Interference (ISI). For broadband communications, OFDM turns a frequency selective channel into a set of parallel flat channels, which significantly reduces the receiver complexity. In this paper, MIMO-OFDM techniques are used to increase the performance efficiency by having multiple transmit and receive antenna for the Rayleigh channel. The reference model SISO, MISO, MIMO(2X2) are designed and simulated in MATLAB. The evaluation of Bit Error Rate (BER) and Signal to Noise Ratio (SNR) performance of the MIMO-OFDM technique combined with Alamouti Space Time Block Codes (STBC) based on 16 QAM over Rayleigh Channels are carried out.

The auxins viz.2,4-D, NAA alone or in combination to BAP (1.0mgl−1) did not induce good quality callus. More than 1ppm IBA formed less and quite compact callus at cut ends with rooting only after two weeks. IBA (0.5-2.0 mgl−1) + 1.0 mg/l BAP increased the mass of pale white, compact, nodular callus with embryogenesis in ten days that differentiated on the callusing media. With IBA and BAP, hypocotyl induced 100.00% callus on all the MS media combinations (1.5mgl−1 IBA + 1.0mgl−1 BAP, 1.0mgl−1IBA +1.0 mgl−1BAP and 0.5mgl−1IBA + 1.0mgl−1BAP), while cotyledons produced maximum callus on MS with 1.5mgl−1IBA + 1.0mgl−1BAP (97.03%). However, cotyledon induced 95.64% somatic embryogenesis on MS +1.5mgl−1 IBA + 1.0mgl−1 BAP followed by leaf (94.10%). Hypocotyl had no somatic embryogenesis on MS media fortified with conc. of 1.5 mgl−1IBA + 1.0mgl−1BAP, which could be increased with further decrease in IBA levels. Callus induced by NAA, 2,4-D and IBA auxins suppressed shoot bud initiation, while IBA +BAP induced callus diverted towards differentiation into shoots on higher levels of BAP+ kin. Furthermore, organogenesis was not observed in the callus induced from the hypocotyl, whereas it was maximum in cotyledon (55.02%) followed by leaf (44.57%) on MS medium supplemented with 2.5mgl−1BAP + 1.0mgl−1kin + 0.2% activated charcoal.

A Proficient Apprehension-Based Mining Replica For Ornamental Text Clustering

— Most of the frequent techniques in text mining are based on the arithmetic scrutiny of a idiom, either word or slogan. Arithmetical scrutiny of a term incidence captures the consequence of the term within a manuscript only. However, two provisos can have the similar regularity in their documents, but one term contributes more to the connotation of its sentences than the further term. Thus, the essential text mining mold should designate terms that incarcerate the semantics of text. In this case, the mining replica can incarcerate terms that current the concepts of the condemnation, which leads to innovation of the topic of the document. A novel concept-based mining replica that analyzes terms on the condemnation, document, and corpus levels is introduced. The concept-based mining replica can efficiently distinguish between non imperative terms with esteem to sentence semantics and terms which hold the concepts that symbolize the sentence connotation. The proposed mining replica consists of sentence-based impression scrutiny, document-based perception analysis, corpus-based concept-analysis, and concept-based resemblance determine. The term which contributes to the condemnation semantics is analyzed on the condemnation, document, and quantity levels relatively than the conventional investigation of the manuscript only. The projected replica can proficiently find considerable toning concepts between documents, according to the semantics of their sentences. The comparison between documents is premeditated based on a new concept-based comparison assess. The proposed correspondence compute takes full improvement of using the perception investigation procedures on the judgment, document, and quantity levels in manipulative the comparison between documents. Large sets of experiments using the projected concept-based mining replica on unusual data sets in text clustering are conducted. The experiments express general contrast between the concept-based investigation and the habitual analysis. Tentative consequences reveal the considerable enrichment of the clustering superiority using the sentence-based, document-based, corpus-based, and united loom concept analysis
