How applications running on a many-core system are mapped to cores largely determines the interference between these applications in critical shared resources. This paper proposes application-to-core mapping policies to improve system performance by reducing inter-application interference in the on-chip network and memory controllers. The major new ideas of our policies are to: 1) map network-latency-sensitive...
Software testing is one of the most important and expensive (in term of time and cost) phase of software development life cycle. Over the past few decades a lot of research has been done on automatic software testing process but due to dynamic memory allocation, software is very much unpredictable in behavior. Different Meta heuristic algorithms are applied for improving the efficiency of software...
Advancement in energy technologies are much needed for social and economical enlargement of our society. The sustainable energy resources and development of efficient module is highly required in present power system. Existing power system is designed as a one way traffic system from source to utility. The objective of this paper is to study the evolution of smart grid to enhance the bidirectional...
Rectangular patch antenna with CPW feed for dual band operation is presented. Parametric analysis of the proposed antenna is performed using AWR Microwave Office software. Return loss measurement has been performed using vector network analyzer. The proposed antenna is suitable for WiMAX and WLAN applications.
This work analyses the hypernasal cleft palate speech for 4-point severity rating (0-normal, 1-mild, 2-moderate, 3-severe). Hypernasality results nasalization of vowels and some of voiced consonants. Addition of extra nasal peak in vicinity of first formant occurs due to nasalization. To resolve the closely spaced extra nasal peak and first formant, a high spectral resolution technique called zero...
With progress in the quantity of cloud users and the extent of thin-skinned data on cloud, fortification of cloud has become more essential. Hence, competent and effectual methodologies are desirable to pledge the data authentication and valuable load management of data. To prevail over these threats linked issues, new-fangled protocol design has been proposed. The pedestal of our design is the in...
In flat-tariff structures we are free to use all of our electronic devices at the same per unit price throughout the day. Due to which, we fail to get the true cost of electricity generation and distribution. Dynamic pricing is a solution to this problem, where a consumer is charged various prices depending upon the demand response curve. Recent researches and Implementation of dynamic pricing of...
Harmonic contamination is a serious problem in Low Tension power distribution systems employing several types of non-linear loads e.g. diode/thyristor rectifiers, cyclo-converters, IGBT/MOSFET based inverters, adjustable speed drives, Switched Mode Power Supply, etc. Each of these load, overheat the distribution transformers and hamper the power quality. Hence, it is necessary to limit the harmonics...
Now there is tremendous appeal of ensuring energy security by using the energy saving. The recent trend is using LED lightning. This paper is the performance analysis of LED and conventional florescent lamps of 22 street lightning load. From the results it can be concluded that LED have reduced power consumption about 40% less not only that capacitors used in LED drivers gives magnificently high power...
The planning of production and other operations in a firm is done based on demand forecasts. But production decisions get affected by actual realization of the demand. These decisions are taken keeping into consideration production capacities. Sometimes sudden and unforeseen demands from customers arise. This kind of situation generally arises when customers of a supplier firm get some new contracts...
Hypernasality is a condition where the speech is highly nasalized resulting in significant reduction of intelligibility. Hypernasality happens due to severe leakage of air through nasal cavity because of either cleft palate and / or incomplete closure of velum. Hypernasality can be visualized as a phenomenon of introducing a nasal formant in the vicinity of first formant. To distinguish the nasal...
This paper presents an efficient technique for harmonic compensation using Ant Colony Optimization (ACO) algorithm for power quality improvement under various loading conditions. ACO employs a set of ants which randomly select the components according to the previous pheromone level distribution. As the time will progress ant will converge to set of components thus completing the optimisation. The...
Even though India started commercial solar PV power plants, the efficiency of the PV system has not been raided. Many investigations have been made material design and characterization. But the major influencing parameters for the solar PV output is environmental parameters like dust, temperature, air velocity etc. In this project an attempt has been made to increase ambient humidity near the panel...
Software testing is a process for insuring the delivery of an error free software to customers. The success or failure of the software to achieve its desirability is depend on the software testing components. All the software industries spend a lot of their money and time for software testing process. Automatic testing is a key area where cost and time of software testing process has been considerably...
As per the finding of Agile development, Testing is recognized not to be a separate phase, but an integral part of Software Development with the Coding. “Whole-team” approach is being used by Agile team to “baking quality in” to the Software Product. Agile team containing the Testers, who lend their expertise in eliciting examples of desired behavior from customers. They collaborate with the development...
We report the effect of Ta underlayer on the structural and the magnetic properties of Permalloy (Ni81Fe19) thin films over a wide range of film thicknesses (tNi–Fe = 10–200 nm). For this purpose, Ta (5 nm)/Ni–Fe (tNi–Fe nm)/Ta (2 nm) films were grown on thermally oxidized Si substrates under the presence and the absence of biasing magnetic field (1000 Oe). The Ni–Fe films grown under the presence...
Photoplethysmography (PPG) and Phonocardiography (PCG) are two important non-invasive techniques for monitoring physiological parameters of cardiovascular diagnostics. The PCG signal discloses information about cardiac function through vibrations caused by the working heart. PPG measures relative blood volume changes in the blood vessels close to the skin. This paper emphasizes on simultaneous acquisition...
In this paper, an analysis of solar irradiation tracking is investigated with various types of hardware arrangement of solar photovoltaic (PV) system e.g. without reflector and with reflector (plane mirror, aluminium foil and plastic thin film etc.) for evaluation of solar energy potential. The study has been carried out for solar irradiation tracking with the various arrangements and the performance...
Now a day in the internet service reliable delivery of packet is main issue. MPLS is such technology that assures about reliable delivery of the Internet services and also provides high transmission speed and minimum delays. To provide reliable delivery of packets MPLS technology includes a mechanism in which switching of data packets can be done on the basis of labels rather than routed on the basis...
We present a numerically study of the transmission of 25Gb/s multimode optical signal comprising of 15 bit nonreturn-to-zero (NRZ) sequence over a length more than 50 meters in a graded index multi-mode (GI-MM) fiber with given specification at 850 nm of wavelength. Further, we study the wavelength dependence of relative delay (RD) and group velocity dispersion (GVD) parameters, and observe RD to...
