 Abstract

Potato has an important role in human food. It was the sixth alimentary product in the world after sugar cane, maze, rice, wheat and milk in 2011 year. Any attempt in the improvement of potato harvester will be valuable. In this study, a new semi-mounted one-row potato digger with rotary blade was designed. It can be connected to rotary potato graders. Transmission system was mechanical from tractor to blade by belt, pulley, gearbox, chain and sprocket. More than sixty percent of Indians is depended on agriculture and State Government for development of agricultural sector has accorded high priority to elevate and boost rural economy. Potato seed being vital input to agriculture, endless efforts are being made to assure availability of quality foods grains to farmers in order to sustain the agricultural development and best vegetables to consumer end. In the present situation, the demand of quality potatoes is very high and our proposed potato planting machine will be more helpful to this industry. In view of above, our work has been formulated with the objective to produce quality potato of paddy through scientific methods and adopting suitable processing methods through development of potato planting machine. The paper presents theoretical aspects regarding the kinematics and dynamics of the potato planting machine and features we have implemented all that is required to sowing and planting of potato seed, which includes tilling, planting, fertilizing and ditching of soil all process in a single operation. The outlook and prediction of high growth of crop of cultivators are very high because intensive soil cultivation requires consistency and reliability. In the meanwhile, cultivators are also expected to work smoothly and cultivate large areas. Our design competes with all these expectations to aid cultivators. They intensively tilt the soil while destroying annoying clods. The soil thus becomes loose and can be used for crease forming and create the basis for a harvest with a higher yield. Furthermore, our prototype model can be converted to full width cultivators with a few manual actions to planting. The machine which we have invented is working properly and the design and fabrication is matched the requirement. The future scope of this work; we have implemented all the process for single row. Whereas, our machine can only support for one single operation and this can be expanded by placing two different tillers, so that, we can sow the seeds in two rows and four rows at a time by increasing the tiller in the same machine. By using the springs it can make it as a flexible.

 Abstract

In a recent growing world, energy requisition is continuous increase at a same time one of challenging work is improve the efficiency of existing machine with available energy sources. Even development with new technology in internal combustion engine does not create much more effect with overall efficiency. Replacement of existing internal combustion engine is also not an effective way, as production of new engine or new machine directly or indirectly consume traditional energy source and, create environment issue. Natural air inspire engine has used atmospheric air which contain 78% nitrogen and 21% oxygen. For effective combustion more oxygen required which is limited with atmospheric air. This paper provides literature review on analysis of engine performance and emission parameter with excessive oxygen with different method to enrichment.

 Abstract

In this Theory, the equivalence between “Mass” and “One Dimensional Imaginary Straight Line” is proved by embedding Mass on Imaginary Line. Also, based upon current experimental data, empirical formula is derived which gives upper limit on energy scale up to TeV with minimum size equal to value of charge (Q). These both concepts with The Standard Model of Particle Physics are used to arrange particles (Fermions and Bosons) in 3 Folds way in 4 th Imaginary Space. Mass of Fermions, % Distribution of Matter, Relation between Inertial/Gravitational Mass with Gluon is shown by self explanatory figures. Nature of Dark Matter, Photons and Dark Energy is discussed, here. Finally, matter-Antimatter Asymmetry through 5 th Dimensional Rotation is proved.

 Abstract

This paper proposes a novel four-quadrant vector controlled induction motor (IM) adjustable speed drive (ASD) framework in light of an as of late proposed matrix converter topology called quasi-Z-source direct matrix converter (QZSDMC). The QZSDMC is shaped by falling the quasi-Z-source impedance arrange and the ordinary direct matrix converter (DMC). The QZSDMC can give buck-support operation voltage exchange proportion controlled by controlling the shoot-through obligation proportion and bidirectional operation capacity. The control system, which depends on the indirect field arranged control calculation, can control the motor speed from zero to the appraised an incentive under full load condition amid motoring and recovering operation modes. The proposed four-quadrant vector controlled IM-ASD framework in view of the QZSDMC topology defeats the voltage pick up restriction of the customary DMC and accomplishes buck and lift condition in four-quadrant modes with diminished number of switches, in this manner accomplishing minimal effort, high productivity, and unwavering quality, contrasted with back-with back converter.

 Abstract

The venture introduces a double voltage source inverter (DVSI) plan to improve the dependability and power nature of the smaller scale lattice framework. The proposed plan is incorporated two inverters, which enables the miniaturized scale matrix to trade control delivered by the appropriated vitality assets (DERs) moreover to reimburse the adjacent nonlinear and uneven load. The control calculations are made in light of immediate symmetrical part hypothesis (ISCT) to work DVSI in framework sharing and lattice implanting modes. The proposed scheme has extended immovable quality, cut down data transfer capacity essential of the essential inverter, cut down cost on account of diminishing in channel size, and better utilization of miniaturized scale lattice control while using reduced dc-interface voltage rating for the key inverter. These segments make the DVSI plot a promising option for miniaturized scale framework providing sensitive weights. The topology and control estimation are endorsed through expansive reenactment and test comes to fruition.

 Abstract

Wireless Sensor Networks (WSN) forms core network of the forthcoming era of IoT. These networks consists of wireless nodes deployed wirelessly with the intent of sensing some physical parameter and sending the measured values to some base station. The transmission is done with the assistance of other nodes in the network working as routers. A sensing node comprises of a microcontroller, a sensing device and radio for transmission. Such a network finds diversified deployment applications and thus presents challenges to the network designers. The most critical parameter to be optimized is the network lifetime and the latency. A most critical aspect for wireless nodes is that these are deployed in large numbers to hostile and harsh conditions and are prone to failures at many times. Also, the nodes are battery driven, executing on low rate and low power consumption (LR-WPAN) protocols designed in such a way that even single Lithium ion battery runs for about 6 months. It is because of these reasons that protocols must be designed carefully to enable evenly battery consumption in all nodes, so as to maximize network lifetime with minimal packet loss. A particular class of wireless sensor Networks is the Real Time WSN in which the time critical needs are to be managed. The contribution of this paper is twofold. It investigates the real time characteristics of the network at MAC Sublayer level in terms of a number of Guaranteed Time Slots (GTS) in the superframe structure. The optimal number of GTS in the superframe is to be chosen in such a way so as to ensure minimum latency and maximum network lifetime. Secondly, it presents a tradeoff of latency and data aggregation at the application layer and gives the relationship between the two in the context of network lifetime. MATLAB is used as a simulation tool and the analytical results presented are in agreement with the simulation model.

 Abstract

Wireless Sensor Networks (WSN) forms the backbone of the most of the applications that are a part of modern living. The applications of WSN ranges from fire alarms in modern buildings to blood-sugar level indicators in Intensive Care Units of Hospitals. These networks are formed using battery powered, portable tiny sensing nodes called motes comprising of a microcontroller, a sensing device and radio for transmission. The Physical and MAC layer protocols of WSN are specified in IEEE 802.15.4 specifications, which accounts for Low Rate Wireless Personal Area Networks (LR-WPAN). These are short range communication networks in unlicensed frequency bands in which a typical Li-ion battery is expected to work even for 1.5 years or more without replacement. Due to increasing complexity and diversified application, such networks presents challenges for the network designers to meet the requirements of the application. This paper presents an analysis of Clustering and Energy Consumption and provides an analytical model of network lifetime. The proposed model investigates energy overhead occurred in cluster setup time in the network using MAC layer beacon signaling. It also analyzes energy consumption in cluster in steady state on the basis of read operations per minute in TinyOS devices. It then gives relationship between the two based on cluster size and steady state duration so as to achieve and evenly consumption of battery power in all the nodes so as to achieve max network lifetime. As the applications of WSN are diversified, no single model is applicable for all deployments. In this analysis Zigbee Humidity sensors is considered as representative class of WSN and model equations are presented in its context. To the best of our knowledge, no energy consumption analysis has been made on the basis of MAC layer beacons for clustering setup-phase application layer data packets for steady state phase. First Order radio energy dissipation model is used and MATLAB is used as simulation tool.

 Abstract

With the Growth of Cashless Economy and Demonetization Mobile Transactions have seen an emerging trends.Mobile wallets gained popularity with emerging trends. However, Transaction through mobile wallets or payment applications is not secure due to breaching of sensitive information by the attacker. When confidential data is breached all the sensitive information is lost. Sometimes even the sender denies that message is not sent by him/her & the receiver denies that message is not received by him/her. Hence, it is required to secure transaction by encryption. This paper shows the comparision in time performance of payment application using two Cryptographic Processes to enhance Confidentiality, integrity, Authenticity & non-repudiation of private or confidential data. One Cryptographic Process includes combination of AES & 2 times ECC and Other Cryptographic process include RSA. In this paper, we have implemented by encrypting the data by AES & ECC and compared the results with RSA.
