The problems of depletion of fossil fuel resources due to large scale production of chemicals and biofuels in future are expected to be solved by lignocellulosic biorefinery approach. Systems are being developed for the production of value-added chemicals including biofuels from lignocellulosic waste materials with improved ecological footprints. The large-scale operation of these systems would be resulting in the huge consumption of fresh water (1.9 – 5.9 m3 water per m3 of biofuel). Fresh w...

Till now the CORDIC algorithm is primarily used to calculate only trigonometric operations. In the proposed work, we extend the Radix-4 CORDIC algorithm to the hyperbolic vectoring mode to implement fast computation of Square-Root. This paper illustrates the implementation of a regular VLSI architecture for Radix-4 hyperbolic vectoring CORDIC on FPGA platform. The speed can further be increased with higher version of FPGA devices. A comparison between Radix-2 and Radix-4 CORDIC algorithm base...

Internet of Things (IoT) cloud networks is itself a pervasive idea where all the physical objects are connected over the internet and are allocated with special self-identifying ability to discover other potential objects to transmit data over the internet. The most important shortcoming of IoT cloud networks which needs immediate addressing is the issue of IoT nodes when used within a virtual network of a cloud system. The IoT nodes often communicate over a virtual network and this communica...

Virtual machine (VM) placement in cloud data centers is a challenging task. With the increasing popularity of cloud computing across the globe, a large number of VMs are to be consolidated on a minimum number of data centers (DCs) to optimize the energy consumption and data center utilization. In this paper, we propose a resource aware approach based on a metaheuristic crow search algorithm (CSA) to consolidate a large number of VMs on minimal DCs to meet the Service level agreement (SLA) and...

Nowadays the need to build an affordable and effective intrusion detection system is a necessity with the events of intrusion or burglary on the rise and as we are approaching towards making our house a smart house in this digital era. The demand for such system is going to increase rapidly if it comes with a feasible price to every household. In most of the prevailing intrusion detection systems, motion sensors are used to detect the presence of an intruder. In this paper, the passive infrar...

A simple frequency reconfigurable microstrip patch antenna (MPA) having three PIN diode switches is proposed in this paper. The switches are essential for producing three reconfigurable frequency states and are placed below the patch in slot area. The simulation results show that the proposed antenna exhibits directional radiation patterns at all frequencies. The performance of the antenna is represented by the help of simulated reflection coefficient along with the radiation patterns. The pr...

Underwater image registration is widely needed for various applications these days. Research has been carried out widely in the area of image registration. Underwater images are degraded due to various factors. For the feature detection and matching, Scale Invariant Feature Transform (SIFT) is the technique used most of the times. This paper proposes improvements in SIFT in order to achieve better registration of underwater images. Gabor filter is used as prefilter and Hausdorff distance is u...

Getting quick response in mobile cloud computing is a newly developing area for research. Delay increases when the user requests (tasks) execute in the cloud environment instead of the mobile device, and it affects the quality of service also. So, cloudlet was introduced to execute the maximum number of tasks that provides the same infrastructure like cloud computing system. We have proposed an algorithm in this paper to optimize the execution delay of mobile applications. To get revolved fro...

Cloud computing is an evolution of Distributed system that has been adopted by worldwide scientifically and commercially. For optimal use of cloud’s potential power, effective and efficient algorithm are required, which will select best resources from available cloud resources for different applications. This allocation of user requests to the cloud resource can optimize various parameters like energy consumption, makespan, throughput, etc. This task allocation or mapping problem is a well-kn...

A highly efficient methodology for generation of nitrogen containing Quarternary Carbon centres via aminative and azidative oxidative dearomatization of phenols has been explored. The same protocol has also been succesfully employed to achieve oxidative peroxidation of Phenols. The simplest metal free reaction conditions delineates an easy break through to the “Trio”- of oxidative amination, azidation and peroxidation. An array of diverse polyfunctionalised heterocycles has been synthesized i...

The development of automatic applications, smart devices, ...

Mining is an essential activity required to be carried out for obtaining the raw materials for infrastructures, goods, carriers and energy. However extreme exploitation of mineral resources leave a negative impact on the environment affect air, water and soil leading to the destruction of ecosystem. Large quantities of waste are generated in the process of mining comprising of solid, liquid and gaseous substances. The solid waste generated due to mining activities are significant because of t...

Air quality is a dynamic and complex environmental phenomenon exhibiting large temporal and spatial variations. Acute air pollution is being faced in urban agglomeration due to rapid economic expansion, increase in population, increased industrial activities and exponential growth in automobiles. Air pollution can threaten the health of human beings, trees, lakes, crops and animals, as well as damage the ozone layer, ecology and property. In an attempt to manage urban air resources, it is nec...

Mouth is the first part of digestive system through which food gets introduced to the digestive tract. An infected oral cavity may result a substandard digestive system and an unhealthy animal. The current study focuses on the effect of 2 mouth bacteria involved in teeth blackening on the growth and development of Drosophila. Various labs are using Drosophila as a model organism to study host-microbes interaction. Once the microbes entered into the gut it secretes various neurosecretory produ...

In recent times, sentiment analysis in low resourced languages and regional languages has become emerging areas in natural language processing. Researchers have shown greater interest towards analyzing sentiment in Indian languages such as Hindi, Telugu, Tamil, Bengali, Malayalam, etc. In best of our knowledge, microscopic work has been reported till date towards Indian languages due to lack of annotated data set. In this paper, we proposed a two-phase sentiment analysis for Telugu news sent...

The advances in GPS enabled mobile devices has led people to share their real-time experiences ubiquitously through various online platforms. Users’ experiences on various services (products), interesting places (famously known as point of interests (POI)), events, movies, etc. are being widely collected these days by various enterprise houses. It helps the community to browse through these online contents before selecting a product or a POI. Recommender system is proven to be a successful to...

Successful academic involvement requires regulation of emotion to extract the maximum benefit from the teaching‐learning process. Emotions facilitate and control much of our cognitive processes, classroom motivation and social interaction. The school curriculum being overtly cognitively loaded undermines the importance of emotion in the classroom. Two prerequisites to motivate children in the classroom are to develop an interest and inquisitiveness among them. However, the monotony of the...
