Crankshaft plays a vital role to transform reciprocating motion into rotary motion. The design and analysis of the crankshaft is very important to improve the performance of I.C. Engine. In general the crankshaft is subjected to different pressure loads with respect to crank angle, therefore design and analysis of the crankshaft is important to increase the life of the four stroke engine. The main objective of this paper is to increase the life of the crankshaft of four stroke diesel engine by changing the main bearing diameter and crank web height in the existing design. The design was done by using CATIA software and analysis was done by using ANSYS. Two types of analysis, i.e. modal analysis and fatigue analysis have been carried out.

The use of composite adsorbent with nano particle additives having high surface area can lead to enhanced heat transfer, higher adsorption capacity and faster rate leading to better adsorber performance. The objectives of the present study were to investigate the effectiveness of nanofluid as a cooling fluid of a composite adsorber by carrying out nanofluid characterization and to investigate adsorption-desorption characteristics of a composite adsorbent for ammonia as an adsorbate.An experimental set up with tube-in-tube type configuration was constructed to monitor the thermal characteristics (heat transfer from and to the adsorber) and ammonia adsorption/desorption rates. The composite of calcium chloride with activated carbon and expanded graphite nanoparticles was made having different concentrations of CaCl2 ranging from 40 % to 80 % in the composite and expanded natural graphite (ENG) content ranging from 0-3 % by weight. The desorption characteristics were studied at different temperatures from 70° C to 110° C. The cooling fluid with and without graphite nanofibers (GNF) was circulated in the inner tube at different flow rates from 5 LPH to 25 LPH.From the experimentation on adsorption-desorption characteristics, it was found that the total amount of ammonia adsorbed increased from 133 g for 50:50 composition of CaCl2:AC to 156 g for CaCl2:AC composition of 50:50 with the addition of 3 % ENG nanoparticles. Also the adsorption process time reduced from 22 minutes to 18 minutes. For 50 % CaCl2 in the composite the temperature at which the maximum desorption occurred was 70°C.So, desorption could occur at lower temperature, which is advantageous as it increases the number of options for heat sources to be used. When nanofluid was used as a cooling fluid of the composite adsorber, the total amount of ammonia adsorbed increased from 79.411 g for basefluid to 90.206 g for 0.4 % graphite nanofiber nanofluid for flow rate of 25 LPH. With the use of composite adsorbent of CaCl2:AC of 50:50 composition and addition of expanded natural graphite (ENG) by 3% and when 0.4 % graphite nanofiber nanofluid was used as a cooling fluid, the maximum ammonia was adsorbed up to the bed length of 600 mm only out of the total bed length of 1 m indicating the possibility of reduction in the size of an adsorber.

Design of Head Expander (HE) for environmental vibration testing components with a required test frequency range has become very important, because it is an interface between electrodynamics vibration shaker and test specimen. The HE subjected to resonant and anti-resonant frequencies due to limitations of mass/stiffness properties. The random vibration and harmonic analysis of existing Head Expander was carried out and validated with tested results in the present work. The proposed new features Head Expander is designed by introducing three different hole-patterns which accommodates the different configurations of work pieces for vibration testing. Modal analysis, random vibration and harmonic analysis were carried out using generalized finite element software, ANSYS. The GRMS values of proposed HE design are compared with GRMS values of NAVMAT P-9492 work and found satisfactory.

The cloud is the web-based computer which allows services to be exchanged. It enables users to use the application on any device with internet or intranet access without having an application installed and allows users to access their personal files and applications. Many people have recently used databases to store their data in the cloud. This is useful because it helps users to save data and allows users to access it anywhere and anywhere. The cloud has changed the way applications and databases are saved. Nowadays, running computing servers are stored in cloud computing. The main consideration of cloud information storage is the protection of cloud-specified information. The modern phenomenon used to store and handle data without investments in resources created many security problems that do not seem fully understood. This article focuses on cloud server information security and integrity. A third-party investigator is completed with the verification of data integrity who can sporadically check data integrity on behalf of his consumers.

In Finite Element analysis the size of mesh plays a critical role. It is closely said that accuracy and number of mesh required for the meshing of the element. This paper presents the effect of the von misses and various constraints on the accuracy of the result. On the basis of the papers referred and guidelines obtained for choosing the appropriate mesh size in finite element analysis has been provided and explained about the von misses stress occurred in the model. The web reinforcement should be strengthened enough to carry tension forces as well as compression forces so that the compression wrinkling is avoided. Von mises proves to be the perfect safe value for the designing of composite structures which involves various stress theories and failure criteria.

A compact ECR ion source was used to investigate the effect that the shape of the plasma electrode (PE) has on the surface production of negative hydrogen (H−) ions. A C12A7 electride PE produced ten times more H-ion current compared with a molybdenum (Mo) PE of the identical design. Four times more H- ion current was obtained when the ion source plasma faces the 45-degree tapered hole opened on the surface of the electride PE as compared to the current obtained from a plasma facing the flat side of the PE. This enhancement in H- ion current may indicate larger surface production of H− ions by the enlarged surface area. A Mo PE also showed a similar effect but with less pronounced H- ion current enhancement. A beam trajectory study showed that the beam divergence was larger when the source plasma faced against the tapered side of the PE.

The source for epithermal neutron production, based on vacuum insulated tandem accelerator (VITA) is under operation at the Budker Institute of Nuclear Physics since 2006. The accelerator provides a high current DС proton beam with energy up to 2 MeV. Numerous improvements to achieve stable tandem work and increase the accelerated proton current were made in more than a decade of experimental operation. These improvements include reduction of the accelerator dark current, modifications for the secondary particles suppression in the tandem gaps, vacuum improvement, upgrades of negative ion source, introduction of additional diagnostics to control and adjust the beam injection and transport. These measures provide the upgraded tandem operation with the accelerated proton current of up 9 mA. Two new schemes of negative ion injection into the tandem were designed and tested. New schemes use the upgraded version of a Penning surface-plasma negative ion source with DС H− beam current of up 15 mA and beam pre-acceleration before injection to tandem. The recent experimental results and its comparison with numerical modelling are presented and discussed.

A negative ion source, which utilizes a conversion of primary high current proton beam into negative ions in a gas target via charge-exchange collisions, is under development in Budker Institute, Novosibirsk. The proposed beam will be used for injection into a tandem accelerator, which is a part of the neutron source dedicated for boron-neutron capture therapy (BNCT). The ion source is designed to produce a beam that contains ≥50% of molecular ions. The initial ion beam current is about 1 A at 30 keV energy. After molecular ion dissociation in a gas target, which produces protons with an energy of 15 keV, and further charge-exchange collisions, the beam after the target will contain about 2% of negative ion species with a current in excess of 10 mA. The negative ion beam is then separated by the magnetic field, accelerated up to an energy of 105 keV and enters the tandem accelerator. This paper presents the results of simulations of the beam formation, acceleration and transport. The arrangement of the ion source and corresponding high voltage power supply are also discussed.
