In this paper, a Double Negative (DNG) metamaterial is presented to enhance the performance of Microstrip Patch Antenna (MPA). The scattering parameters are used to design and validate the DNG structure. The proposed DNG is then used as a superstrate of MPA. To compare the performance a conventional MPA without DNG is also simulated. The results show that MPA with DNG has improved performance in terms of directivity, gain and efficiency. The gain is increased by 1.53dB. The efficiency is increased from 62% to 84% approximately. The proposed DNG based MPA can be a good candidate for use in advanced wireless communication systems.

To bridge the semantic gap between different offered ontologies, Ontology Engineers have proposed and implemented various matching techniques during the last decade. Still, these techniques require more efforts and investigations to achieve better precision and recall for the set of alignments. The ontology alignment process consists of mainly three different stages; namely, String based, Linguistic based and Structure based. This paper presents the evaluation and analysis of various linguistic based ontology alignment techniques and their performance during the overall alignment process. For this purpose, we have included those linguistic matching tools which are widely used in the alignment systems whose performance is relatively better in terms of precision and recall during the tests conducted for Ontology Alignment Evaluation Initiative (OAEI). The results presented in this paper were obtained using benchmark ontologies used in OAEI conference. The results and analysis shows the significance of linguistic tools in the overall alignment process. The analysis presented in this paper can also be used as future guidelines for the research community who utilizes the linguistic matchers for finding the semantically equal entities from different ontologies.

In this paper, the design, simulation and optimization study of a rectangular microstrip patch antenna (MPA) for ultra wideband (UWB) wireless body area network is presented. The UWB technology provides wideband wireless communication using very narrow pulses and at very low spectral densities. The Federal Commission of Communication allocates the bandwidth of ultra wideband from 3.1GHz to 10.6GHz for the unlicensed radio applications. The proposed antenna is designed and simulated in Agilent advance design system - momentum, an electromagnetic simulator that works on method of moment technique. The antenna is designed using RT/duroid 5880 (εr = 2.2 and h = 0.381mm), a thin and flexible substrate suitable for wearable antennas in body area networks and FR4 substrate (εr = 4.6 and h = 1.6mm). The dimensions of the proposed design for both the substrates is calculated using the well known transmission-line model. An offset feeding technique is used to feed the antenna. The maximum achieved antenna gain and bandwidth using RT/duroid 5880 substrate is 2.96dBi and 8.3GHz, whereas using FR4 substrate is 2.52dBi and 7.7GHz, respectively. The proposed design uses a reduced ground plane technique to achieve the wide bandwidth characteristic.

Effort estimation is a key component of planning a software development project. In the past, there has been a lot of research on estimation methods for traditional applications but, unfortunately, these methods do not apply to Extract Transform Load (ETL) projects. Coming up with a systematic effort estimate for ETL projects is a challenging task since ETL development does not follow the traditional Software Development Life Cycle (SDLC). Traditional application development is requirements-driven whereas ETL application development is data-driven. This research paper describes the development of an effort estimation model for ETL projects and compares this model with the most widely used algorithmic effort estimation model i.e. COCOMO II. A dataset comprising 220 industrial projects from five different software houses is used to build this effort estimation model using Forward Stepwise Regression. After eliminating 20 outliers from this dataset, the adjusted R2 (i.e. goodness of fit) of our model is 0.87. The prediction and training accuracy of this model is measured using the de-facto standard accuracy measures such as MMRE and PRED(25). On a training dataset of 200 projects, the training accuracy value of PRED(25) is 81.16% and MMRE is 0.16. Results show that our proposed estimation model provides considerably better estimation accuracy as compared to COCOMO II. On a validation dataset of 58 projects, the value of PRED(25) was 49% for our model as compared to 21% for COCOMO II. Furthermore, the MMRE of our model is 0.31 as compared to 0.99 for COCOMO II.

The paper describes the optimization of a discrete-time controller designed on the basis of discrete root locus for the boost converter operating at 1000 kHz. The optimization is accomplished through a nonlinear least squares method. The digital control theory is not as rich as the analog control theory. Locating poles and zeros directly in the z-plane by a designer to render the required performance is a difficult task to accomplish. Direct placement of poles and zeros may also introduce distortion as well. Consequently, direct digital design approach based digital controller may not offer satisfactory performance. The poles and zeros are disturbed around their nominal positions through the optimization technique to snub the atrocities introduced by the unwanted digital phenomena. Effect of nonlinearities in the form of ADC/DAC quantization error, delay, etc. on performance is also accentuated. The effectiveness of the application of the optimization technique to the buck converter is investigated using the MATLAB/Simulink environment.

The intent of 4G technology is to converge high speed data application requirements and compete with other technologies. Different techniques i.e relaying, carrier aggregation, multiple input multiple output, and heterogeneous networks provide higher throughputs, low latency and enable LTE to become a Standard for Wireless broadband. Due to almost exponential increase in demand for high data rates it is expected that network will be occupied by more resource demanding applications. Therefore efficient scheduling of radio resources is required for better performance of LTE system. Proportional Fair scheduler is adopted to LTE system to achieve Orthogonal Frequency Division Multiple Access (OFDMA) potentiality in Time Domain systems (TDS) and Frequency Domain scheduling systems (FDS). This paper aims at enhancing the functionality of Proportional Fair algorithm by making future estimation of the channel quality index (CQI) to offer higher data rate among all users according to their running applications, at high mobility. Performance of proposed algorithm on the downlink is measured in terms of throughput and block error rate using a MATLAB-based system level simulator.

The paper presents the estimation of an unknown non-linear system in ARX form. The estimated model is used in Adaptive self-tuning regulator to regulate the output of plant at desired reference input using Minimum Degree Pole Placement Controller (MDPP). Most of the literature includes the conventional RLS algorithm to estimate the system parameters. The estimation technique addressed here is Fuzzy Logic Identifier (FLI). The proposed estimator approximates the system using a linear model at each operating point. The linear identification of model necessitates the use of linear control strategy. Therefore, the design of MDPP controller based on linear identified system is also presented. The consequents of FLI are updated using Levenberg-Marqardt (LM) algorithm. MATLAB/Simulink is used for the implementation of proposed estimation techniques. The effectiveness of the proposed estimators and control strategy is tested on a non-linear plant. The results are presented and debated together with a comparative analysis of RLS and FLI. Superiority in performance is found for FLI in estimating and controlling the non-linear using MDPP. The performance indices Mean Square Error (MSE), Mean Absolute Error (MAE) and Mean Time-Weighted Error validate the effectiveness of proposed FLI.

Therefore, the design of MDPP controller based on linear identified system is also presented. The consequents of FLI are updated using Levenberg-Marqardt (LM) algorithm. MATLAB/Simulink is used for the implementation of proposed estimation techniques. The effectiveness of the proposed estimators and control strategy is tested on a non-linear plant. The results are presented and debated together with a comparative analysis of RLS and FLI. Superiority in performance is found for FLI in estimating and controlling the non-linear using MDPP. The performance indices Mean Square Error (MSE), Mean Absolute Error (MAE) and Mean Time-Weighted Error validate the effectiveness of proposed FLI.","PeriodicalId":166507,"journal":{"name":"2015 International Conference on Emerging Technologies (ICET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131344760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
