 Abstract

Soil moisture information plays an important role in environmental monitoring, agricultural production and hydrological studies. Particularly, agricultural yield depends on several growing parameters like temperature, humidity, soil moisture and pH of the soil, etc. In this paper, we have designed and developed a system for measuring and monitoring soil moisture, humidity and temperature by interfacing low-cost soil moisture sensor FC-28, temperature and humidity sensor: DHT11, and using Internet of Things (IoT), Cloud computing and Mobile computing technologies. We have also implemented an online cloud computing system to keep check over soil parameters. Various methods, both laboratory and field including remote sensing are available to measure soil moisture content, but the quickest and better one is with the use of soil moisture sensor electronic devices. For successful irrigation, it is necessary to monitor soil moisture, its temperature and humidity content continuously in the irrigation fields. The soil moisture sensors are used intensively at present because it gives real time readings. Their usage helps growers with irrigation scheduling by providing information about when to water the crops. Efficient irrigation watering helps in saving water, getting better plant yields, reducing dependency on fertilizers and improving crop quality. This research has a real potential to deliver a more productive and sustainable form of agricultural production, based on a more precise and resource-efficient approach. It also promises to reduce the ecological footprint of farming, make farming profitable and boost customer acceptance.

 Abstract

We introduce an effective technique to enhance the images captured underwater and degraded due to the medium scattering and absorption. Our method is a single image approach that does not require specialized hardware or knowledge about the underwater conditions or scene structure. It builds on the blending of two images that are directly derived from a color-compensated and white balanced version of the original degraded image. The two images to fusion, as well as their associated weight maps, are defined to promote the transfer of edges and color contrast to the output image. To avoid that the sharp weight map transitions create artifacts in the low frequency components of the reconstructed image, we also adapt a multi scale fusion strategy. Our extensive qualitative and quantitative evaluation reveals that our enhanced images and videos are characterized by better exposedness of the dark regions, improved global contrast, and edges sharpness. Our validation also proves that our algorithm is reasonably independent of the camera settings, and improves the accuracy of several image processing applications, such as image segmentation and key-point matching.

 Abstract

Communicative Language Teaching (CLT) method offers English as Second Language (ESL) learner�s purposeful classroom activities to help them acquire communicative competence. In nutshell, communicative competence is knowing how to produce and understand different types of texts and also knowing how to maintain communication despite by having limitations in ones language knowledge. In a CLT classroom, the students as a community learn to communicate through collaboration and sharing. The role of the teacher is not only to create opportunities for language learning but also to train the students to reflect on their language use for effective learning. This paper discusses on how communicative language teaching (CLT) is adapted in present ESL classrooms through communicative activities like Role play, group discussions, just a minute (JAM) and Talk show interview to help ESL learners communicative.

 Abstract

The digital world we live in demands a high application of digital signal processing, neural networking, computer automation. Multiplier is one of the essential operators for these applications. The demand for power efficiency and higher speed introduces errors into these applications. These demands give birth to a new field known as Approximate computing. In the paper approximate multiplier is designed with a huge range of dynamic selection. One of the main advantages of the design is the error introduced during a computation, which cancels with previous computation instead of summing up. An approximate DRUM multiplier is designed using Verilog. Register Transfer Level (RTL) is retrieved. The computation of error metrics is done in MATLAB. This design is scalable and so it can be used according to the required application. The propagation delay of the multiplier is reduced in this design which makes it faster. Error analysis is done based on various parameters and it is observed the error introduced is least among all the approximate multipliers. Since multiplier consumes more power in the processor, this multiplier is designed with power efficiency as one of the major constrain. As designed the multiplier when used in a processor saves power to 58 %. The design outperforms various other approximate multipliers which was analyzed during the literature survey. After analyzing the DRUM multiplier a modification is done in the design to improve the accuracy. This optimized design is termed as Optimized DRUM multiplier and it is analyzed and the comparative study between both the multipliers is made in terms of accuracy.

 Abstract

Inability to speak is considered to be true disability. People with this disability use different modes to communicate with others, there are many number of methods available for their communication one such common method of communication is sign language. Sign language allows people to communicate with human body language, each word has a set of human actions representing a particular expression. The motive of the paper is to convert the human sign language to Voice with human gesture understanding. This is achieved with the help of Raspberry pi web camera and speaker. There are a few systems available for sign language to speech conversion but none of them provide portable user interface. For consideration if a person who has a disability to speak can stand and perform in front of the system and the system converts the human gestures as speech and plays it loud so that the person could actually communicate to a mass crowd gathering. Also the system helps visually and speech impaired people to communicate with each other.
