Statistical approximation properties of Stancu type -Baskakov-Kantorovich operators
In the present paper, we consider Stancu type generalization of
Baskakov-Kantorovich operators based on the q-integers and obtain statistical
and weighted statistical approximation properties of these operators. Rates of
statistical convergence by means of the modulus of continuity and the Lipschitz
type function are also established for said operators. Finally, we construct a
bivariate generalization of the operator and also obtain the statistical
approximation properties.Comment: 16. arXiv admin note: substantial text overlap with arXiv:1508.0586
Wishbone bus Architecture - A Survey and Comparison
The performance of an on-chip interconnection architecture used for
communication between IP cores depends on the efficiency of its bus
architecture. Any bus architecture having advantages of faster bus clock speed,
extra data transfer cycle, improved bus width and throughput is highly
desirable for a low cost, reduced time-to-market and efficient System-on-Chip
(SoC). This paper presents a survey of WISHBONE bus architecture and its
comparison with three other on-chip bus architectures viz. Advanced Micro
controller Bus Architecture (AMBA) by ARM, CoreConnect by IBM and Avalon by
Altera. The WISHBONE Bus Architecture by Silicore Corporation appears to be
gaining an upper edge over the other three bus architecture types because of
its special performance parameters like the use of flexible arbitration scheme
and additional data transfer cycle (Read-Modify-Write cycle). Moreover, its IP
Cores are available free for use requiring neither any registration nor any
agreement or license.Comment: 18 page
A Efficiency & Latency based Compression of Hierarchical Network and Flat Network
Wireless Sensor Network (WSN) compromised of maximum number sensor nodes which cooperatively send data to base station. These networks are worn in various applications outline such as habitat monitoring, environment, military, and security, etc. As the sensor nodes are broadly operated over battery driven, an efficient utilization of power is essential. Therefore, to increase the lifetime of a sensor network, power efficient methods has to be fitting to choose and aggregate data. It's essential because of the majority
PAPR Reduction Using Low Complexity PTS to Construct OFDM Signal
Orthogonal frequency division multiplexing has become evident due to its higher frequency multiplicity to achieve high data rate and greater immunity to multipath fading. The imperative drawback of OFDM is its high peak-to-average power ratio which results in power inefficiency. There are numerous techniques used to overcome problem of high PAPR in OFDM modulation system. Partial transmit sequence (PTS) is most prominent peak-to-average power ratio (PAPR) reduction techniques proposed for orthogonal frequency-division multiplexing (OFDM) systems. The main drawback of the conventional PTS (C-PTS) is its higher computational complexity and transmission of several side information bits. A new PTS with simple detector is recommended here to deal with these drawbacks of C-PTS. The candidates can be generated by cyclically shift of each sub block sequence in time domain and combining them in a recursive manner. At the receiver, by using the natural diversity of phase constellation for different candidates, the detector can successfully regain the original signal without side information. The probability of detecting failure of the side information found that detector can work without any side information with high reliability. The scheme in this paper achieves almost the same bit error rate (BER) performance as the C-PTS with perfect side information, under additive white Gaussian noise (AWGN) channel and Rayleigh fading channel
PERFORMANCE AND EMISSION ANALYSIS OF CONSTANT SPEED SI ENGINE OPERATED ON HYTHANE (HCNG)
Energy is the basic need of human to survive in this dynamic world. The whole world is toiling hard to meet its energy demands. Every country in this world has high energy demand owing to its increasing population which is posing a threat to energy sustainability. Generally, Energy is consumed in Agriculture, Residential and Transportation sector in which transportation sector has a high percentage of energy consumption. Conventional fuels which are used to power vehicles are having limited reserves. In the present scenario, Petroleum reserves are depleting at a faster rate and causing environmental pollution. It has inspired the researchers to develop new alternate fuels. Alternate fuels are having significant energy content and lower emissions as compared to conventional fuels. Alcohol, Biodiesel, Liquefied Petroleum Gas (LPG), Compressed Natural Gas (CNG) and Hydrogen are the alternate fuels which are being used today. CNG is being used extensively all over the world. CNG is having low laminar burning velocity which makes it more prone towards knocking. Hydrogen has high laminar burning velocity which makes it a better supplement to CNG. The blend thus obtained by mixing Hydrogen and CNG is known as Hythane or HCNG. Hythane has the advantages of both the parent fuels which make it a promising fuel for automotives. This paper includes the effect of Hydrogen addition to CNG which is tested on a single cylinder, four-stroke, water cooled SI engine. Determination of optimum percentage of Hydrogen in CNG and emissions analysis is also included in the paper
Selection of Combat Aircraft by Using Shannon Entropy and VIKOR Method
The selection of military defense equipment, especially fighter aircraft, has a bearing on the readiness ofthe Indian Air Force to defend the country’s independence. This study analyses a collection of alternative fighteraircraft that are linked to several choice factors using a multiple-criterion decision-making analysis technique. Tohandle such scenarios and make wise design judgements, a variety of criterion decision analysis techniques can beused. In this study, we assess fifth-generation fighter aircraft that incorporate significant 21st-century technologicaladvancements. These aircraft represent the state-of-the-art in fleet planning operations to 2022. These are generallyequipped with quick-moving airframes, highly integrated computer systems, superior avionics features, networkingwith other battlefield elements, situational awareness, command, control, and other communication capabilities.The study proposes a strategy for the selection of the fifth-generation combat aircraft for the National Air Force.Because of the problems, the Army needed an application that could assist with decision-making for combat selection systems. Solving the decision problem for evaluating fifteen military fighter alternatives in terms of nine decision criteria is the main objective of this work. We use the Shannon entropy and VIKOR model for the Air Force’s fleet program to evaluate military fighter aircraft suitability. The entropy technique is used to compute the weight of the criteria, and then the VIKOR technique has been used to rank the fighter aircraft

Antagonistic Effects of Plant Growth Promoting Bacteria Against Bacterial Diseases of Black Gram
Vigna mungo, the black gram, urad bean, mash kalai, uzhunnu parippu, ulundu paruppu, minapa pappu, Uddu (in Kannada) or black matpe is a bean grown in South Asia. Like its relative, the mung bean, it has been reclassified from the Phaseolus to the Vigna genus. The product sold as black lentil is usually the whole urad bean, whereas the split bean (the interior being white) is called white lentil. It should not be confused with the much smaller true black lentil (Lens culinaris).Black gram originated in South Asia, where it has been in cultivation from ancient times and is one of the most highly prized pulses of India. It is very widely used in Indian cuisine. In India the black gram is one of the important pulses grown in both Kharif and Rabi seasons. This crop is extensively grown in southern part of India, northern part of Bangladesh and Nepal. In Bangladesh and Nepal it is known as mash daal. It is a popular daal (legume) side dish in South Asia, that goes with curry and rice as a platter. Black gram has also been introduced to other tropical areas such as the Caribbean, Fiji, Mauritius, Myanmar and Africa. It is an erect, suberect or trailing, densely hairy, annual bush. The tap root produces a branched root system with smooth, rounded nodules. The pods are narrow, cylindrical and up to six cm long. The plant grows 30–100 cm with large hairy leaves and 4–6 cm seed pods. While the urad dal was, along with the mung bean, originally placed in Phaseolus, it has since been transferred to Vigna.present study is based on antagonistic effects of plant growth promoting bacteria against bacterial diseases of black gram
A comparative study of the anti-nociceptive potential of duloxetine and carbamazepine in an animal model of neuropathic pain
Background: Pain is one of the most common symptoms encountered in clinical practice. Of the various types of pain, neuropathic pain represents one of the most difficult pain states to treat, with treatments being far from satisfactory. The drugs used are not fully effective and a drug that shows good efficacy in one neuropathic pain state may be ineffective in another. This study was done to compare the antinociceptive potential of duloxetine and carbamazepine, two drugs with different mechanisms of action in an animal model of neuropathic pain.Methods: Antinociceptive effect of duloxetine (15 mg/kg intraperitoneally) and carbamazepine (20 mg/kg intraperitoneally) was evaluated in the sciatic chronic constriction injury (CCI) model of neuropathic pain in rats. Thermal hyperalgesia, evaluated by the hot plate method; and mechanical hyperalgesia, evaluated by the pinprick method were used as measures of neuropathic pain.Results: A significant degree of thermal and mechanical hyperalgesia (p ≤0.05) was produced in both the drug groups. Both drugs produced a significant decrease in thermal and mechanical hyperalgesia throughout the study period (p ≤0.01 for both drugs). In comparison to duloxetine, carbamazepine was less efficacious (p ≤0.05 at 30, 60 minutes; p ≤0.01 at 120 minutes) for thermal hyperalgesia as well as for mechanical hyperalgesia (p ≤0.05 at 30, 60 minutes; p≤0.01 at 120 minutes). Only duloxetine was able to almost completely reverse both thermal & mechanical hyperalgesia to near pre-neuropathy levels.Conclusions: Duloxetine showed better antinociceptive potential as compared to carbamazepine as reflected by a more complete reduction in thermal & mechanical hyperalgesia in the sciatic CCI model of neuropathic pain
