The Mazdaspeed 3 car is a Fuel Efficient Compact Car as it provides better acceleration and smooth delivery of power without compromising on fuel economy. With less fuel consumption, the car has six-speed manual and six-speed automatic transmission.
High frequency variable oscillator is central to the construction of high speed clock for data communication. A very wide variable frequency oscillation is designed that could be used in data communication for reliable and fast data transmission. A voltage controlled oscillator in Colpitt configuration is used in the design. The design is found to be capable of producing frequencies from 800MHz to 1.5GHz for a reverse biased voltage (VR) of 0 to 25V while maintaining a good tuning flatness throughout the range. The design is found to be free from noise and frequency variations over the tuning range.

In Communication system, the system capacity and performance are adversely affected and degraded by interference. Hence, power control plays a prominent role in an interference-limited system, which increases the efficiency by mitigating the adjacent and co-Channel interference in the system. In this paper, primarily power control is said to be used in maintaining the acceptable Carrier to Interference Ratio (CIR) by meeting some Quality of service (QoS) requirements Objective function that is defined as maximum channel capacity in a power constraint scenario. The signals in a radio channel undergo different propagation effects like reflection, refraction, scattering and shadowing. Hence, the distribution of users across subcarrier groups as well as their transmission powers within a given cell has a significant effect on how users and power are accordingly distributed elsewhere in the network to maximize the capacity of the system thereby enhancing its performance
Tukra is one of the major problem in mulberry growing areas and it is caused by pink mealy bug Maconellicoccus hirsutus which affect both the quality and yield of mulberry leaf. In general the tukra- diseased leaves showed high moisture content compared to normal healthy leaves. A preliminary attempt has been made to know the effect of plant extracts of natural pesticide origin on moisture content, loss and retention capacity of tukra affected mulberry leaves. The seed kernel and leaf extracts of Azadirachta indica, Pongamia pinnata, Madhuca longifolia and only leaf extracts of Lantana camara, Adathoda vasica were directly used as a foliar spray on M-5 mulberry variety under field conditions. The results revealed that the tukra affected leaves showed high moisture content (75.92%) compared to normal healthy leaves (71.32%). The moisture content was more in NSKE @ 4% (73.83%) PSKE @ 4% (73.80%), MSKE @ 4% (73.30%), and lowest was recorded from MSKE @ 2% (71.76%)
Cloud computing is the apt technology for the decade. It allows user to store large amount of data in cloud storage and use as and when required, from any part of the world, via any terminal equipment. While Cloud services offer flexibility, scalability and economies of scale, there have been commensurate concerns about security. On the similar terms, we have chosen to make use of a combination of authentication technique and key exchange algorithm blended with an encryption algorithm. In this project, we have proposed to make use of 3DES algorithm which is a well-known symmetric cryptosystem and is widely used for secure data transmission, along with that we will blend it with Random Key Generator and Graphical Password to add an extra security measure. This proposed architecture of three way mechanism and the use of symmetric method of encryption make it tough for hackers to crack the security system, thereby protecting data stored in cloud.
Development is explain not as an empirical term (Reese and Overton1970) and on occasion as through it is (Kaplan 1983) . Many times as what ever happens across the life span is what constitutes development. The concept of development centers on value based notion of improvement. In life span perspective the development is life long, interactive, multidimensional, culturally historically embedded process, shows plasticity, involves both gain and losses and has multidisciplinary field of study. (Sugarman 2001) The quality of life is interpreted differently as satisfaction (Summers 1976), happiness( Esterling 1978),psychological wellbeing( Andrews and Withey 1978) and degree of fulfillment of individuals important goals(Frish 1089) .In Positive Psychology the scientifically unwieldy notion of happiness is broken down several more quantifiable aspect: positive emotion (the pleasant life) engagement (engaged life) and purpose(meaningful life). (Seligman 2008)
Clustering technique is the basic technique used in the wireless sensor network to enhance the lifetime of a sensor network by mitigating energy consumption and provide efficiency, scalability, and security. Formerly sensor nodes are considered to be homogeneous in which each node has the same processing capacity, energy and functionality, but to prolong network lifetime researches has been evolved to infuse heterogeneity in wireless sensor network such as to provide different energy level to some nodes. In this paper, we present a survey on basic clustering techniques for Heterogeneous wireless sensor networks.
This paper presents Computational Fluid Dynamics (CFD) analysis of Pelton turbine of Khimti Hydropower in Nepal. The purpose of CFD analysis is to determine torque generated by the turbine and pressure distributions in bucket for further work on fatigue analysis. The CFD analysis is carried out on model size Pelton runner reduced at 1:3.5 scale to minimize computational cost and time. The operating conditions for model size runner is selected in accordance with IEC 60193 and IEC 1116. The paper describes the methods used for CFD analysis using ANSYS CFX software. 3 buckets are used to predict the flow behavior of complete Pelton turbine. k-ε and SST turbulence model with interphase transfer method as free surface and mixture model is compared in the paper. The pressure distribution is found maximum at bucket tip and runner Pitch Circle Diameter (PCD). The torque generated by the middle bucket is replicated over time to determine total torque generated by Pelton turbine.
Gray level Slicing is to highlight a specific range of gray values. Power Adaptation methods are presented for gray level slicing approaches. Power Adaptation methods aims in optimization of the resulting bit error rate by gray level slicing without preserving background and gray level slicing with background. This paper gives us an achievable increase in the proposed method rather than the conventional method with a better quality and the bit error rate is also optimized in proposed method rather than the former method with acceptable quality.
