Improving Swelling and Strength Behavior of Black Cotton Soil Using Lime and Quarry Dust

Abstract: Black cotton soil, classified as highly expansive soil, is found in arid and semi-arid parts of the world where the damp condition arises, causing immense soil swelling, followed by a prolonged period of drought, wherein wide-deep cracks within the soil mass get developed that possesses a threat to engineering structures built on it. This paper is an attempt to improve the swell-shrink behavior and strength characteristics of black cotton soil by using a common stabilizer lime along with quarry dust in varying percentages. The results of the study revealed that differential free swell, liquid limit reduced and unconfined compressive strength increased on adding optimum lime content to black cotton soil. Further, on adding quarry dust alone and in combination with lime, differential free swell and liquid limit reduced, whereas unconfined compressive strength increased.

An Optimal Tree-Based Routing Protocol Using Particle Swarm Optimization

Abstract: Wireless sensor networks (WSNs) contain many sensor nodes which are deployed in the various geographical areas to perform various tasks like monitoring, data aggregation and data processing. For performing all these operations, energy is highly consumed, thus sensor nodes begin to die soon and also creates energy holes in some of the geographical locations. All the sensor nodes are powered by battery, and it is quite difficult to replace the battery, and so energy consumption is prime objective to increase the network lifetime. Clustering and tree-based routing like LEACH, PEDAP, TBC and TREEPSI solves most of the energy consumption problem as it saves energy during a lot of operations in WSNs. In this paper, we propose an optimal tree-based routing protocol (OTBRP) that is efficient in terms of stability period (time period before first node dead) and therefore offers good network lifetime. The parameters like first node dead, half node dead and last node dead are considered for the measurement of network lifetime. In order to evaluate the performance of OTBRP, the comparison is made with the GSTEB and PEGASIS. Simulation results show that there is a gain of approx. 200 and 150% in stability period in comparison with PEGASIS and GSTEB, respectively.

A Survey on Internet of Things (IoT): Layer-Specific, Domain-Specific and Industry-Defined Architectures

Abstract: Labelled as “The next Industrial Revolution”, Internet of Things (IoT) is the technology giant which is rapidly gaining ground in the scenario of modern wireless sensor networks (WSNs) where physical objects (or “things”) are connected through the common platform, ie Internet The Internet of Things paradigm is paving the way towards success, providing services in different domains Single architecture is not enough to provide essential services in all domains The reference model can be made to provide a starting point for developers looking further for developing strong IoT solutions In order to facilitate future research and to help the product builder to choose from the different architectures, this paper does an analysis of layer-specific, domain-specific and industry-defined IoT architectures Intel, IBM and CISCO have also made a push towards developing new models that aims to standardize the complex and fragmented IoT industry by releasing IoT platform reference architectures This paper contributes the IoT, basic elements of IoT, systematic classification of different IoT architectures and comparison of industry-defined architectures

The Jugaad Technology (Indigenous Innovations) (A Case Study of Indian Origin)

Abstract: "The jugaad mindset is crucial. It's not just jargon." says Ananth Krishnan, chief technology officer of Tata Consultancy Services. Jugaad or Indigenous innovation is the tool not a jargon it is the basically a mindset of the innovator. In which he used his/her skills and traits to make things in productive way. Jugaad is the most economical way to do task or a particular work. In India there is huge problem of employment in rural as well in urban areas jugaad is the new opportunity to those youth who has some new ideas and they are willing to do the work this provide self employment to the youth in their own areas or regions it also helps in inclusive growth of the India. This study will find the scope of the indigenous innovations (Jugaad’s) and work towards the patent of the technology so that everyone can use these as per in Indian rural areas the scarcity is more for employment as well as for resources. We used the case study method for the evaluation. The cases are taken from different parts of rural India.
