CFD analysis of combustion chamber of SI engine during suction stroke
This work is suitable for the IC engine design and analysis industry in understanding the various performance characteristics of the flat and dome head piston. The design of the piston and chamber has a vital role in the optimized performance of an engine. There are lots of studies undergone about the new piston geometries and designs to achieve the optimized results. Studies about the piston and combustion process include both the structural and thermal analysis because both pressure and temperature are the two important properties which affect the performance of the piston and chamber. This work designs a new model of flat and dome piston for an assumed optimized output of the existing engine and chamber. This work will be helpful for the new inventions in engine development. In this work piston and chamber are modelled in CATIA v5 software and these models are imported into ANSYS software and analysis is employed. Structural and thermal analysis of the piston and air flow analysis of the chamber is employed for both flat and domed piston.

Synthesis of FeOOH by electrochemical deposition techniques
We are conducting FeOOH platelets were successfully synthesized on ITO substrate by an electrochemical deposition method also conducting a multi-disciplinary research work that involves the development of nanostructured thin films of semiconductors for different applications. Nanotechnology is widely considered to constitute the basis of the next technological revolution, following on from the first Industrial Revolution, which began around 1750 with the introduction of the steam engine and steelmaking. Nanotechnology is defined as the design, characterization, production, and application of materials, devices, and systems by controlling shape and size of the nanoscale. The nanoscale itself is at present considered to cover the range from 1 to 100 nm. All samples prepared in thin film forms and the characterization revealed their nanostructure. The major exploitation of thin films has been in microelectronics, there are numerous and growing applications in communications, optical electronics, coatings of all kinds, and in energy generation. A great many sophisticated analytical instruments and techniques, largely developed to characterize thin films, have already become indispensable in virtually every scientific endeavor irrespective of discipline. Among all these techniques, electrodeposition is the most suitable technique for nanostructured thin films from aqueous solution served as samples under investigation. The electrodeposition of metallic layers from aqueous solution is based on the discharge of metal ions present in the electrolyte at a cathodic surface (the substrate or component.) The metal ions accept an electron from the electrically conducting material at the solid- electrolyte interface and then deposit as metal atoms onto the surface. The electrons necessary for this to occur are either supplied from an externally applied potential source or are surrendered by a reducing agent present in solution (electroless reduction). The metal ions themselves derive either from metal salts added to the solution, or by the anodic dissolution of the so-called sacrificial anodes, made of the same metal that is to be deposited at the cathode.

A review on mouth dissolving tablets of Glimepiride
Oral route is considered as the most common and preferred technique for drug administration because it is considered as the easiest and simplest method. The route provides simplicity of drug administration in a handy way and individuals tend to be more knowledgeable about this particular route. The latest developments in Novel Drug Delivery System (NDDS) seeks for improving effectiveness and molecules security that were used previously by preparing a suitable dosage forms for administration. Now a days the problems such as dysphagia are faced by the conventional dosage forms like capsules and tablets, which results in ineffective therapy because of high incidence of non-compliance. Mouth dissolving tablets (MDTs) were developed to prevent above issues in conventional dosage forms. These MDTs have easy administration, dose uniformity, and good hardness as well as are the first preference for the travelling, geriatric, and pediatric patients. This paper provides a review for MDT because of its wide significance, as well as such drug delivery system may help for better compliance of patient along with ultimate clinical output.

Agricultural drone interaction tank interface
Application of crop protection materials is one of the crucial operations in agriculture to meet ever demanding food production. The drone mounted sprayer mainly consists of BLDC motors, LiPo (Lithium Polymer) batteries, pesticide tank, pump, and supporting frame. Six BLDC motors were mounted to the hexa-copter frame to lift of 1 kg payload capacity. One LiPo batteries of 3 cells -5200mAh were used to supply the necessary current required for the propulsion system. A 1-liter capacity conical-square shaped fluid tank was used to hold the pesticide solution.

Bidirectional Z-Source converter with hybrid system fed PMDC motor for electric vehicles
The bidirectional DC-DC converters have been widely used in micro-grids, renewable energy systems, electric vehicles and other applications to ensure the power flows from and to, or between various energy storage devices. Energy storage systems have been a major research area in which battery is one of the most widely used. A new battery ultra-capacitor hybrid energy storage system is proposed for electric vehicles. The main objectives of using ultra-capacitors alongside battery is to improve the performance, increase the system efficiency and extend the battery life. In many applications, conventional bidirectional converters are inadequate since the specified range of input voltages and the specified range of output voltages call for an extremely large range of conversion ratios. A new bidirectional z- source converter with high voltage gain in both step-down and step-up operation modes is used here. In this work, an Ultra Capacitor is integrated with the battery in an Electric Vehicle using the new bidirectional converter to improve the dynamic performance of the vehicle system and enhancing the battery life. The simulation work is carried out using MATLAB/SIMULINK R2015 software. Hardware is made and the control strategy is implemented using TMS320F28027.

Optimization of virtual machines in cloud environment
Emergence of cloud computing has facilitated the provisioning of computing resources in an on-demand basis that can be swiftly allocated, released and reallocated with minimum management effort and cost. One important element of cloud is the virtual machine which encapsulates business services and acts as a resource carrier. An important task of cloud computing is to find an optimal placement scheme that can map the virtual machines to physical machines. With the increasing prevalence of large scale cloud computing environments, how to efficiently place VMs into available computing servers has become an essential research problem. This research works presents a Virtual Machine Placement and Load Rebalancing Based on Multi-Dimensional Resource Characteristics in Cloud Computing Systems (VMP-LR) to improve the efficiency of VM placement
