Crop pest is an organism that creates damage on to the agriculture by feeding crops. The research focuses on four major types of crop pest which occurs on teff, wheat, sorghum, barley and maize these are Black tef beetles, Ageda korkur, Degeza and Yesinde Kish Kish. The aim of this paper is identification of the four types of agricultural crop pest using a computer vision technique. The image of crop pest were taken from Amhara regions of Ethiopia i.e. Adiet, Dejen, Gonder, Debremarkos (places where images were taken).  In this paper, artificial neural network (ANN), a hybrid of self organizing map (SOM) with Radial basis function (RBF) and a hybrid of support vector machine (SVM) with Radial basis function (RBF) are used, and also we used Otsu and Kmeans segmentation techniques. Finally we selected Kmeans techniques for segmenting crop pest. In general, the overall result showed that using kmeans segmentation in RBF and SVM perform better than using otsu method in the other algorithm and the recognition performance of the combination of RBF (Radial basis function) and SVM (support vector machine) is 93.33%.

A Compressed Sensing Signal Processing Research

10.11591/ijeecs.v3.i1.pp119-125
Guojun Qin , Jingfang Wang
The classical Shannon/Nyquist sampling theorem tells us that in order to not lose information when uniformly sampling a signal we must sample at least two times faster than its bandwidth. Nowadays in many applications, because of the restriction of the Nyquist rate, we end up with too many samples and it becomes a great challenge for further transmission and storage. In recent years, an emerging theory of signal acquirement, compressed sensing(CS), is a ground-breaking idea compared with the conventional framework of Nyquist sampling theorem. It considers the sampling in an novel way, and open up a brand new field for signal sampling process. It also reveals a promising future of application. In this paper, we review the background of compressed sensing development. We introduce the framework of CS and the key technique and illustrate some naïve application on image process.

Pulsed electric fields (PEF) is a novel non-thermal food processing whose purpose is inactivating microbes while at the same time preserving food’s nutrition, color, and taste. This paper presents an analysis of step up transormer for PEF high voltage generator. To achieve the optimum PEF effects, the pulse shape should resemble a square, which is characterized by low voltage drop and fast rising time. Through simulations, it has been shown that higher transformer inductance results in lower voltage drop. However at some points, further increasing the inductance would only produces negligible improvements. Meanwhile fast rising time can be achieved by minimizing leakage inductance and parasitic capacitance. Moreover, maximum energy transfer to the load can be obtained by reducing winding resistances. Finally, a case of high voltage generator using ignition coil has been evaluated. Due to its high winding resistances, ignition coil seems to be not suitable for PEF applications.

Hardware Implementation of 3-level Inverter using Microcontroller for Single Phase Induction Motor

10.11591/ijres.v5.i2.pp96-102
Veena B.M. , Parimala S.K.
The conventional two level inverter has many limitations for high voltage & high power applications. The term multilevel began with the three-level inverter. Subsequently, several multilevel inverter topologies have been developed. However, the elementary concept of a multilevel inverter to achieve higher power is to use a series of power semiconductor switches with several lower voltage dc sources to perform the power conversion by synthesizing a staircase voltage waveform. Output voltage of 3 level inverter consists of 3 levels, which results smoother output. And hence the THD will be reduced. In this paper Simulink of 3 level inverter and the hardware implementation of micro controller based control of multilevel inverter for single phase Induction motor are presented.

Crosstalk is one of the problems that affect the performance operation of global system mobile (GSM) network. Among the effect of crosstalk are call mute, call drop, wire propagation delay, dynamic power dissipation etc. Crosstalk is an undesirable signal arising due to the coupling capacitances between adjacent interconnecting wires and measured in decibel. In this paper some literature were reviewed and different ways of measuring crosstalk such as Near end croosstalk (NEXT), far end crosstalk (FEXT), Power sum crosstalk (PSNEXT) and alien crosstalk (AXT) were analyzed.

The paper presents the computation and measurement of electric field, in both electrostatic as well as ionized case, for dual electrode system intended for electrostatic applications. The dual electrode system consists of an ionizing and non-ionizing electrode have the same voltage and facing a grounded collecting plate. The charge simulation method (CSM) coupled with genetic algorithms (GAs) and method of characteristic (MOC) is applied to compute the electrostatic field and the ionized field respectively. The influence of dual system parameters such as ionized wire diameter and inter electrode distances on the profile of the electrostatic field on the collecting plate and on the surface of the ionizing wire has been studied. The measurements of the ionized electric field, current-voltage characteristics and ion current density profiles are implemented using the technique of the linear biased probe. An experimental setup is constructed to model the present electrode arrangement. The measurements are carried out for ionized wire of diameter 0.25 and 0.5mm. The computed results are found to be in good agreement with experiments.

Warehouse is one of the most dangerous places to work because of many potential dangers. The accidents caused by heavy vehicles result in seriousinjuries and even death. This paper proposes a solution to this problem. When a worker happens to be in any of such hazardous situations inside or outside workplace, he will press the emergency button (or pull a magnetic cord) placed in the smart safety belt which will not only stop the vehicles within 15 meters circle but also inform the workers within 250 meters circle through an indicator. In this technical paper, the outcome of first design phase has been reported. In the first design phase, we have successfully implemented a reliable and accurate ranging mechanism with ±0.3m maximum error. This ranging mechanism is based on wellknown RF Time-of-Flight (TOF) method. The maximum achievable transmit range of this solution is 300m.

VLSI Design and Comparison of DA and LMS Based Reconfigurable FIR Filter

10.11591/ijres.v5.i2.pp121-126
P. Hemanthkumar , Y. Sai Kiran , V. Nava Teja
Here, we exhibit the design optimization of one- and two-dimensional fully-pipelined computing structures for area-delay-power-efficient implementation of finite impulse response (FIR) filter by systolic decomposition of distributed arithmetic (DA)-based inner-product computation. This plan is found to offer a flexible choice of the address length of the look-up-tables (LUT) for DA-based computation to determine suitable area-time trade-off. It is seen that by using smaller address-lengths for DA-based computing units, it is possible to decrease the memory-size but on the other side that leads to increase of adder complexity and the latency. For efficient DA-based realization of FIR filters of different orders, the flexible linear systolic design is implemented on a Xilinx Virtex-E XCV2000E FPGA using a hybrid combination of Handel-C and parameterizable VHDL cores. Various key performance metrics such as number of slices, maximum usable frequency, dynamic power consumption, energy density and energy throughput are estimated for different filter orders and address-lengths. Obtained results on analysis shows that performance metrics of the proposed implementation is broadly in line with theoretical expectations. We have seen that the choice of address-length M=4 gives the best of area-delay power-efficient realizations of the FIR filter for different filter orders. Moreover, the proposed FPGA implementation is found to involve significantly less area-delay complexity compared with the existing DA-based implementations of FIR filter.
