Non-convex Economic Load Dispatch using Cuckoo Search Algorithm

10.11591/ijeecs.v5.i1.pp48-57
N. Karthik , A.K. Parvathy , R. Arul
This paper presents cuckoo search algorithm (CSA) for solving non-convex economic load dispatch (ELD) problems of fossil fuel fired generators considering transmission losses and valve point loading effect. CSA is a new meta-heuristic optimisation technique inspired from the obligate brood parasitism of some cuckoo species by laying their eggs in the nests of other host birds of other species. The strength of the proposed meta-heuristic optimization technique CSA has been tested and validated on the standard IEEE 14-bus, 26-bus and 30-bus system with several heuristic load patterns. The results have indicated that the proposed approach is able to obtain significant economic load dispatch solutions than those of Firefly Algorithm (FFA) and other soft computing techniques reported in the literature.

Packet Delay Distribution Model for Investigating Delay of Network Speech Recognition

10.11591/ijeecs.v5.i1.pp11-18
Asril Jarin , Suryadi Suryadi , Kalamullah Ramli
Unlike multimedia streaming applications that require a smooth playback at the client, application of network speech recognition (NSR) that recognizes speech signal in a sentence-by-sentence manner might tolerate an acceptable delay. The acceptable delay is a user-defined time in which the entire sentence data should be received by the server. We proposed a calculation method to investigate the acceptable delay of network speech recognition that employs a speech segmenter to send speech signal sentence-by-sentence over TCP channel to the server. The calculation multiplies the mean packet delay of TCP flow at steady-state with the number of created packets. For validation we implemented a MATLAB program and solved it using 2500 Indonesian speech sentences. The results were then compared with the results of our previous model that used a transient analysis method. It was found that this calculation method is not appropriate due to the transient behavior of the streaming sentences.

10.11591/ijeecs.v5.i1.pp81-84
Hadaate Ullah , Ridoanur Rahaman , Shahin Mahmud
Cadmium (Cd) is a soft, silver-white or blue lustrous metal typically found in mineral deposits with lead, zinc and copper. Cadmium Oxide thin films have been prepared on a glass substrate at 3500C temperature by implementing the Spray Pyrolysis method. The direct and indirect band gap energies are determined using spectral data. The direct and indirect band gap energies decrease with the increasing film thickness. It is noted that for the same film thickness the direct band gap energy is greater than indirect band gap energy. The transmittance increases with the increasing wavelength for annealed and deposited films. It is also noted that for the same wavelength the transmittance for deposited films is greater than the transmittance for annealed films.

Ontology Matching using BabelNet Dictionary and Word Sense Disambiguation Algorithms

10.11591/ijeecs.v5.i1.pp196-205
Mohamed Biniz , Rachid el Ayachi , Mohamed Fakir
Ontology matching is a discipline that means two things: first, the process of discovering correspondences between two different ontologies, and second is the result of this process, that is to say the expression of correspondences. This discipline is a crucial task to solve problems merging and evolving of heterogeneous ontologies in applications of the Semantic Web. This domain imposes several challenges, among them, the selection of appropriate similarity measures to discover the correspondences. In this article, we are interested to study algorithms that calculate the semantic similarity by using Adapted Lesk algorithm, Wu & Palmer Algorithm, Resnik Algorithm, Leacock and Chodorow Algorithm, and similarity flooding between two ontologies and BabelNet as reference ontology, we implement them, and compared experimentally. Overall, the most effective methods are Wu & Palmer and Adapted Lesk, which is widely used for Word Sense Disambiguation (WSD) in the field of Automatic Natural Language Processing (NLP).

Efficient Phase Recovery System

10.11591/ijeecs.v5.i1.pp123-129
Mohamed Saber
An efficient, stable and reliable system to detect the unknown phase of the input sinusoidal signal is presented. The proposed design is a feedback loop consists of subtractor, peak detector and direct digital synthesizer (DDS). DDS generates a sinusoidal signal with the same frequency of input signal and with initial zero phase. An error signal is the output of subtracor after subtracting DDS signal from input signal. The peak of amplitude of error signal has a mathematical relation to the phase difference between the two input signals. Peak detector is used to extract the phase difference from error signal and passes the result to DDS to control the generated phase. The loop continues until the generated phase of DDS is the same as the input unknown phase. The proposed phase estimator has been implemented using a field programmable gate array (FPGA), consumed less power about 330 mW, and worked at 200 MHz clock.

Electrical Conductivity of Polyaniline Fiber Synthesized by Interfacial Polymerization and Electrospinning

10.11591/ijeecs.v5.i1.pp85-89
Ngurah Ayu Ketut Umiati , Kamsul Abraha , Kuwat Triyana
Polyaniline fiber is a promising biosensor material due to the capability of this material as an effective mediator for electron transfer. The polyaniline in fibre has wider surface to increase the electron transfer. In this work, polyaniline structure synthesized by interfacial polymerization was compared to polyaniline structure obtained from electrospinning to get a better fibre structure. Interfacial polymerization was carried out to form a polymerization between the water phase and the organic phase. The water phase was prepared from dopants, initiator and aquadestilata and the organic phase was was made from toluene as an organic solvent and aniline monomer. Electrospinning was conducted by using a dc high voltage 15 kV and 0.5 mm syringe needle to produce fibers from a melt polymer solution taken from interfacial polymerization. The scanning electro microscope results confimed the formation of polyaniline in structure of fiber. Resistance measurement by using LCR meter showed that polyaniline fiber resulted from electrospinning is more conductive than polyaniline fiber formed by interfacial polymerization method.

10.11591/ijeecs.v5.i1.pp115-122
Abrham Debasu Mengistu , Dagnachew Melesew Alemayehu
Dialect is a difference of verbal communication spoken by people from a particular society or geographic area so the paper focuses on Amharic language dialect recognition. In this paper,  the authors have used backpropagation artificial neural network, VQ(vector quantization), (Gaussian Mixture Models) and a combination of GMM and backpropagation artificial neural network for classifying dialects of Amharic language speakers. In this research, a total of 100 speakers for each group of dialects are considered each having about 10 seconds duration is collected. The feature vectors of Mel frequency cepstral coefficients (MFCC) had been used to recognize the dialects of speakers. In this research paper the recognition model that uses a tanh activation function have a better result instead of using the Logistic Sigmoid activation function in backpropagation artificial neural network. After conducting the above experiments 95.7% accuracy achieved when GMM and backpropagation artificial neural network with tanh activation function are combined.

Power distribution networks are considered the main link between power industry and consumers and they are exposed to public judgment and evaluation more than any other section. Thus, it is essential to study power quality in distribution section. On the other hand, power distribution networks have always been exposed to traditional factors such as  voltage sag, voltage swell, harmonics and capacitor switching which destruct sinusoidal waveforms and decrease power quality as well as network reliability. One of the methods by which power quality problems might be addressed is to apply power electronic devices in the form of custom power devices. One of such devices is Dynamic Voltage Restorer (DVR) which is connected in series to distribution networks. At the same time, through injection of voltage to the network it is able to control voltage amplitude and phase. It is  adopted lend to compensate for voltage sags through injecting series and synchronous three phase voltage. This paper reviews on the application of DVR for Voltage Compensation in recent years and gives sets of information for each control of the DVR in distribution networks.

Data Integrity and Security [DIS] Based Protocol for Cognitive Radio Ad Hoc Networks

10.11591/ijeecs.v5.i1.pp187-195
Azeem Mohammed Abdul , Syed Umar
In the CRN (cognitive Radio Networks) the main issues to be addressed are spectrum scarcity and inadequate usage of spectrum. The CRN can analyse the unused spectrum, so that CRN users can easily occupy the unused spectrum without blocking the existing Primary Users. In a CRN, routing is a complex issue because of channel diversity. The existing system mainly focuses on the performance analysis of Ad hoc On-Demand Distance Vector (AODV) and the Weight Cumulative Expected transmission time (WCETT). The performance of these protocols are measured and compared in various ways such as the throughput of single radio station multi-channels, equal number of radio stations and channels, multi-radio stations multi-channels. The limitation with these protocols is, whenever a route fails, there is issue to get connected with the other nodes, the other being data integrity, which maintains the no loss of data [LOD]. In our proposed DIS – CRAHN system we overcome these limitations by adding data security and integrity. Security is provided using the RSA algorithm while Integrity is ensured using the SHA algorithm. With the data security we can maintain the shortest path from source to destination and if any route failure occurs then immediate route establishment can be done and data encryption and decryption also be implemented using the random key generation. Results show an improved performance in delay with reasonable throughput, making the protocol an ideal choice for CRNs.
