Perception of multimodal objects in NLP through computer vision
Get PDFThis project is based on voice interaction and object detecting properties. It will allow the users to do voice interaction with the artificial intelligence and it will reply with the system voice. That is how users will use their voice to command as a trigger to find out the category of any object by showing it using the camera module. At first, the user will show an object with the help of a camera and ask for identifying it in the system. The object detection system then captures a frame from the camera and predicts through the structure to identify which class the object belongs to by extracting the feature from there. The process of this application is to search the database to match the structural data to find out the exact category of the object. When this system approximately matches with the information of a category then the application will suggest the category for the object by mentioning the category name through voice. This application can also give some basic information by asking for it. Our general-purpose approach can be effective in interpreting the structure and properties of objects in different networks through natural language processing
Static and dynamic wireless charging system for electric vehicle
Get PDFElectrified transportation will help to reduce greenhouse gas emissions and petrol prices. Electrified transportation demands that a wide variety of charging networks be set up, in a user-friendly environment, to encourage adoption. Wireless electric vehicle charging systems (WEVCS) can be a potential alternative technology to charge electric vehicles (EVs) without any plug-in problems. This paper outlines the currently available wireless power transfer technology for EVs. In addition, it also includes wireless transformer structures with a variety of ferrite shapes, which have been researched. WEVCS are associated with health and safety issues, which have been discussed with the current development in international standards. Two major applications, static and dynamic WEVCS, are explained, and up-to-date progress with features from research laboratories, universities, and industries is recorded. Moreover, future upcoming concepts-based WEVCS, such as ‘‘vehicle-to-grid (V2G)” and ‘‘in-wheel” wireless charging systems (WCS) are reviewed and examined, with qualitative comparisons with other existing technology
Selaginella likabalika Aran & Roy sp. nov: a new species from Arunachal Pradesh, India
Get PDFA new species of Selaginella i.e., Selaginella likabalika is described in the present study. The species was collected from Likabali, under the Lower Siang district and Karsingsa, under the Papumpare district of Arunachal Pradesh. The new species can be easily confused to be mosses due to their similar appearance and habitat resemblance. The species is minute, prostrate and generally covers the ground like a carpet. The morphology of the new species is close to Selaginella armata, S. apoda, S. confusa and S. flacca but can be differentiated by leaf features
Factors influencing consumers’ attitude towards online shopping in Rangpur City
Get PDFNowadays Bangladesh is called a “DIGITAL BANGLADESH”. The propensity of online shopping and businesses is increasing these days. The digital environment spreads out not only in the country but also in Rangpur City. Over the last few years, online shopping has improved and the number of people who have access to the web has increased. A positive attitude towards online shopping and selling is being observed in Bangladesh. The young generation is much more involved in space marketing or shopping than in a place. The main aim of this research is to investigate the consumers’ attitudes toward online shopping and the factors influencing consumers towards online shopping. To meet the study objectives a quantitative survey method was employed. Researchers select 150 respondents by the technique of non-probability convenience sampling. The questionnaire of the study was developed from the previous literature. The research result shows that 60% of the respondents are male, and the rest are female between the 16-59 age groups, with a Secondary school certificate to postgraduate educational level. Most of them spend 2-4 hours on the Internet daily. The result also revealed that convenience, time-saving, website design, perceived enjoyment, and people engagement and their review rating have a significant positive relationship with consumer attitudes toward online shopping
Bioherbicidal potential of Rumex crispus infected with Didymella rumicicola
Get PDFA new foliar disease was observed on a perennial weed Rumex crispus which grows extensively in orchards, pastures, hay crops, lawns and home gardens in Kashmir valley. Repeated Isolation of the pathogen from the infected leaves of Rumex crispus yielded the fungus which on the basis of Cultural and morphological characteristics showed a resemblance to Didymella sp. Pathogenicity was confirmed by the detached leaf technique as well as inoculating whole plants in pots. Precise confirmation of the identity of the pathogen was done by sequencing the reference genes using ITS1 and ITS4 markers and sequenced data was subjected to BLAST which showed 99.80 per cent similarity with Didymella rumicicola which was previously only reported in New Zealand on Rumex obtusifolius prior to this study. Host range, as well as bioherbicidal potential of this pathogen on hosts of five different families of cultivated crops along with Rumex plants, revealed that no disease incidence was found on host plant species of other families of cultivated crops, whereas,100% disease incidence and 80% severity were observed on Rumex crispus at 15 and 25 days after inoculation respectively. Physiological studies showed the newly isolated pathogen Didymella rumicicola showed the best radial growth on Potato dextrose agar at pH 6.5 and at a temperature of 25oC
Inselbergs: potential conservation areas for plant diversity in the face of anthropization
Get PDFFaced with the loss of biodiversity, particularly plant diversity, due to anthropogenic pressure, particular ecosystems such as inselbergs can constitute refuge areas. The objective of this study is to determine the conservation potential of plant biodiversity on inselbergs in Burkina Faso. A comparative study was carried out between inselberg’s vegetation and the surrounding plains vegetation. In each of these vegetation types, stratified and random sampling was adopted and data were collected in plots of 900 m² for the woody stratum and 100 m² for the herbaceous stratum. The specific diversity was evaluated through the effective numbers of Hill of order Q = 0; 1; 2. The Hill index does not vary between inselbergs and plains and thus reflects a strong similarity in floristic diversity between the two ecosystems. Sorensen’s similarity coefficient also shows a similarity in terms of floristic composition between inselbergs and surrounding plains. In inselbergs, relict species that have disappeared from the surrounding plains of some phytogeographic sectors occur. The flora of inselbergs is also characterised by indicative species of anthropized ecosystem absence. However, these species are present on the surrounding plains. Indeed, the flora of inselbergs is characterised by 11 endemic species. Inselberg’s vegetation is characterised by unique plant communities such as rock pools and Afrotrilepis pilosa mats. The exploitation and mortality rates of woody plants are significantly higher on the surrounding plains than on the inselbergs. The flora and vegetation of inselbergs show the absence of indicator species of disturbed ecosystems. They present endemic and relict species and stable woody stands. Due to the steep slope, lack of suitable soil for agriculture and sacred status of someones, the inselbergs constitute a refuge for plant species and thus contribute to the conservation of biodiversity like the protected areas
Organic management of tuberous intercrops for resilience, higher yield and profit from coconut plantations: Insights from validation experiments in Kerala, India
Get PDFFifteen on-farm experiments were conducted in tropical tuber crops intercropped in coconut gardens in Thiruvananthapuram, Kollam and Pathanamthitta districts, Kerala, during 2018-2021 for validation of organic production technologies. The validation experiments were performed under the aegis of the ICAR-Central Tuber Crops Research Institute, Thiruvananthapuram, in a project funded by the Coconut Development Board, Kochi, Kerala. Three treatments viz., T1: organic farming technology (OF), T2: POP recommendation (POP) and T3: farmer's practice (FP) were evaluated in cassava, elephant foot yam and greater yam intercropped with coconut. System productivity and profitability were worked out for the different treatments based on yield and income from coconut and tuber crops in the respective treatments. Pooled analysis indicated that the coconut yield under intercropping with tuber crops in organic mode was high by 7-13% in comparison to monocrop of coconut maintained by the farmers. Tuber yield under organic management was superior over POP by 14% and FP by 27%. On an average, the net income from coconut-tuber crop intercropping system under organic management was ₹ 2,36,133 ha-1, whereas it was ₹ 1,56,904 ha-1 in POP and ₹ 1,32,706 ha-1 in FP and significantly outperformed sole coconut (₹ 7,764 ha-1). Thus, the results indicated that organic management of coconut-tuber crop system offered resilience with higher system productivity and profitability
Prospects of coconut cultivation in Tamil Nadu – A SWOT Analysis
Get PDFCoconut is an important horticultural crop of the state of Tamil Nadu spreading across an area of 4.44 lakh hectares. Coconut is a victim of the catastrophes of climate change events like high temperature, excessive or deficit rainfall and increased atmospheric CO2 concentration. Coconut plantations in the state are hit by several pests and diseases, some of which are lethal, fatal and are debilitating in nature. An analysis of Strength, Weakness, Opportunities and Threats (SWOT) for the prospects of coconut cultivation in the state revealed that edaphic and climatic factors, less labour requirement compared to other field crops of the state and access to technologies remain the great strength, while tropical cyclones hitting coastal districts of the state, failure of monsoon, wide fluctuations in copra price, lack of producer-centric market intelligence are the striking weakness for coconut cultivation. Improved varieties and hybrids with desired traits, establishment of processing industries, international cargo terminals to tap export market and crop insurance scheme in the event of climatic aberrations, remain the major opportunities while declining soil fertility, debilitating pests and dreadful diseases and poor scientific management owing to the fragmented land holdings are the major threats of coconut cultivation in the state of Tamil Nadu
Community farm school approach for coconut seedlings/juveniles through collaborative social actions
Get PDFThree Grama Panchayats in Kerala's Alappuzha district undertook community-level participatory action research in 2019–2021. A total of 90 coconut farmers participated in the adoption of ICAR-CPCRI technology to produce West Coast Tall (WCT) coconut seedlings that are resistant/tolerant to the root (wilt) disease at the community level. Partners included extension agents, coconut producers' societies (CPS) and clusters, women self-help groups (WSHGs), and agricultural labor organizations. The characteristics of technologies that are suggested for adoption in root (wilt) disease-affected tracts, such as the scientific management of young coconut trees and the production of high-quality seedlings through community nurseries, challenge the idea of adoption. There are a lot of variances in the homestead gardens' marginal holdings, including expertise, the use of technology, and access to advisory services. Government agencies provided the majority of the seedlings and extension advisory services, emphasizing the necessity for FPO-based or private extension in the coconut growing industry. The coconut farmers' understanding has significantly improved as a result of the participatory interventions for managing seedlings. The participatory demonstration and community farm school (CFS) strategy is discussed in the paper as a way for homesteads to manage juvenile coconuts while integrating new ideas and fostering cross and reciprocal learning. Refining the current extension approach requires integrating new knowledge about the characteristics of seedling growth, future economic performance, and social evaluation of choices of technological, individual, and skill-oriented interventions in risk-prone areas with debilitating root (wilt) disease
Understanding the dynamics of phosphorus sorption in acidic soil amended with cocoa pod husk biochar
Get PDFCocoa pod husks (CPH) generated from cocoa gardens, after separation of beans from cocoa pods, were converted to biochar through pyrolysis. Though biochar itself is a source of many vital nutrients, it has got high capacity for nutrient sorption, much more than natural organic matter, by some estimates even 10 to 100 times. In soils, phosphorus exists mostly in organic and inorganic forms and many times become a limiting nutrient in acidic and alkaline soils because of adsorption, precipitation and complexation. Hence, better understanding of phosphorus sorption dynamics in soil is a key to know the bioavailability of P in a soil. In this study, an attempt was made to examine the P sorption vis-à-vis desorption properties when cocoa pod husk biochar is applied in an acidic soil with three different levels of phosphorus availability. The biochar was applied @ 0, 5, 10, 20 and 40 g kg--1 to the acidic field soils which received inorganic fertilizer with and without organics and also unfertilized soils. Phosphorus retention and release was studied by fitting the equilibrium solution and sorbed concentrations of P by adsorption isotherms. The results showed that in all the soil biochar incubation treatments, increased biochar addition led to an increase in the soil available P and the P activation coefficient. In the sorption-desorption study, it was found that phosphorus sorption increased with increasing rates of biochar application. The addition of biochar at 20 g kg-1 and 40 g kg-1 increased the equilibrium solution P concentration and increased available P as compared to lower doses of biochar. Also, fertilized soils sorbed more phosphorus (323.25 – 995.27 mg kg-1) than un-fertilized soils (347.25 - 805.47 mg kg-1) @ 0–40 g kg-1 biochar. All the treatments fitted satisfactorily with Langmuir equation (r2 = 0.96–0.99, P = 0.01) and Freundlich equation (r2 = 0.87–0.99, P = 0.01). In this paper, we explain the phosphorus adsorption features using Langmuir equation as the main isotherm. The conclusion drawn from this study was that the addition of CPH biochar could alter the P availability, which is directly related to the phosphorus sorption dynamics of the soil
