Efficient Data Transfer Over Wireless Networks

In the present day, efficiency in the field of communication is of utmost importance. In this study, data is transmitted over a wireless network supported by helical antennas. The efficiency is obtained by encoding the data by the Reed Solomon (RS) encoding scheme. The added advantage of this encoding scheme is its error detection and correction scheme in addition to the productive bandwidth usage. The data is encoded from the source and will be modulated using Quadrature Amplitude Modulation (QAM) scheme. The modulated data is then transmitted over a wireless network supported by the helical antenna. In the receiving end, the received signal is demodulated and then decoded. In this study, errors are introduced by the user to demonstrate the error detecting and correcting capabilities. The entire set up is simulated on the MATLAB version 9.5b 2018 software

Standardisation of soil volume wetting for drip irrigation in mango (Mangifera indica L.,)

Field experiments were conducted in mango for four years during 2017-2020 at ICAR-Indian Institute of Horticultural Research to standardise optimum soil volume wetting for drip irrigation. Wetting soil volume upto 70% recorded higher mean fruit yield of 34.8 kg/plant (9.68 t/ha)and with further increase in the level of soil volume wetting irrigation (upto 80%), there was a decline in the mango yield (7.40 t/ha). Similarly, significantly increased response was observed in fruit weight upto 70% soil volume irrigation (226 g) although there were no significant differences in the TSS of the fruit. Significantly higher water use efficiency was observed for 30% soil volume wetting irrigation (274.1 kg/m3) and further no significant differences were observed in water use efficiency between 50% and 70% soil volume wetting irrigations indicating that in areas of water scarcity, it is enough to scheduling the irrigation only upto 50% soil volume wetting in mango for economising the water (232.1 kg/m3)

Comparison of clinical profile of urban vs. rural Indian youth with premature coronary artery disease (PCAD): a sub-study of the PCAD registry

Background: We aimed to compare clinical profile of premature coronary artery disease (PCAD) in urban vs. rural Indian populations.Methods: This was a prospective cross-sectional observational multi-centre study. This study is a sub-study of the ongoing PCAD registry. Between the period April 2017 and April 2018, a total of 1061 patients <40 years with PCAD were studied. Urban (n=583) and rural (n=478) populations were statistically compared.Results: Mean age of the urban and rural populations were 34.50±4.15 years and 33.99±4.46 years, respectively. All cardiovascular risk factors (smoking, diabetes, hypertension, dyslipidemia, obesity, diet and family history), except for alcoholism were more prevalent in urban subjects compared to rural subjects. However, higher prevalence of only hypertension (p=0.05) was statistically significant. Religion was significant between the two populations (p<0.001). Window period was also significant between the two populations (p<0.001). Very low density lipoprotein cholesterol (VLDL) (p=0.037) was significantly different between both populations.Conclusions: All conventional risk factors were more prevalent among urban populations than rural populations, however none of these differences except for hypertension was statistically significant

MOBILE INTEGRATED SMART IRRIGATION SYSTEM USING IoT

Today’s world, the scarcity and usage of water is increasing day by day, it is very much important to conserve water for the future generation. The water requirement is very much needful for irrigation system and at a same time, proper management of water is also very much important with the available sources. Therefore a smart system is essential to manage the same. These papers present a smart system developed for irrigation system using IoT (internet of things). The main purpose of this system is to periodically monitor the soil’s moisture, humidity and temperature levels which are very much required for the crops, based on requirements, the water supply is pumped to the field and at the same time the farmer will receive the real time information to farmer's smart phone

SHARE AND USE

Android is one of the most user friendly mobile platforms that have grasped the attention of smart phone users around the globe. According to stats available there are 1.4 billion people who have used Android mobile platform. And this has led to the development of android application exponentially; there are around 2.8 million android applications available in play store. Many of the available application do not fit into low specification smart phones due to some reasons. Share and Use is an android application that lets you use another smart phones application by your phone without actually installing it on your phone. Share and Use lets user to use application installed on other phones and access applications on their smart phones. Share and Use helps phones with lower specification android phones to use applications that are not be able to install in them

Multi-resolution texture classification based on local image orientation

The aim of this paper is to evaluate quantitatively the discriminative power of the image orientation in the texture classification process. In this regard, we have evaluated the performance of two texture classification schemes where the image orientation is extracted using the partial derivatives of the Gaussian function. Since the texture descriptors are dependent on the observation scale, in this study the main emphasis is placed on the implementation of multi-resolution texture analysis schemes. The experimental results were obtained when the analysed texture descriptors were applied to standard texture databases

Variations in the esterase activity during the germination period of Jatropha curcas seeds

Germination brings out the synthesis or activation of enzymes responsible for the degradation of seeds reserves. Among these enzymes, esterases are involved in the metabolic processes of germination and maturation of plants. They are constitutively expressed in seeds during germination to release the reserve materials for the growing embryo. In the present study, total protein content and esterase activity was monitored in germinating Jatropha curcas seeds. The esterase activity and specific activity observed were 9.07 µmoles/min/gm and 0.09258 IU/mg, respectively. Electophoretic analysis for esterase activity showed thirteen bands of esterases, among these 8 esterolytic bands were major and remaining were minor bands. The protein content and esterase activity decreased on 2nd, 4th, 5th and 8th day of seed germination and activity increased on 3rd, 6th, 7th day of germination. Similarly esterase activity increased on 7th day and decreased on 8, 9 and 10th day in the shoot tissue. ÂÂ
