In this paper, we propose a less complex algorithm based on a mixture PLL-based loop for estimating and tracking parameters in non-linear model. The algorithm can work with both the physical channel model (assuming time delays information) and the equivalent discrete-time channel model. In the algorithm, we combine two techniques the PLL-based loop and the Sequential Monte Carlo Sampling in order to track the channel complex gains and unknown carrier frequency offset (CFO). Afterwards, the channel matrix can be simply constructed, and then the data symbol can be estimated with free intercarrier interference (ICI) by using MMSE equalizer. It is shown that our algorithm has a good performance in terms of MSE and BER and approaches the BER of the ideal case for which the channel response and CFO are known. Moreover, the proposed mixture has less complexity compared to the mixture with kalman filter.","PeriodicalId":421311,"journal":{"name":"The Third International Conference on e-Technologies and Networks for Development (ICeND2014)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121205784","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}

The data were gathered using a qualitative approach. This includes conducting interviews and discussion groups among 40 respondents who are mainly staff of the hospital (doctors, nurses, administrative, IT personnel). The study was conducted based on the outcome of an earlier study, which indicated that the adoption of ICT at Saudi Arabian hospitals was affected by many factors. Moreover, end users of ICT are believed to have encountered many challenges while using this technology. At the same time, there are many benefits which can be gained from the use of ICT, such as improvement in the quality of work, productivity, and educational tools for both users and patients. In addition, the use of ICT can lead to more accurate diagnoses, help solve health-related problems, and reduce medical errors, apart from helping ICT users to evaluate themselves. It also helps in decision making and improving patients' safety, particularly at KFMC.","PeriodicalId":421311,"journal":{"name":"The Third International Conference on e-Technologies and Networks for Development (ICeND2014)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126105402","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}

Mid-InfraRed (MIR) spectroscopy reflects fundamental molecular vibrations whereas Near-InfraRed (NIR) spectroscopy exhibits the overtones and combinations of fundamental vibrations and bonds. In most applications, the samples are mixed with potassium bromide (KBr) powder, or simply unmixed. Two technics are investigated: IR absorption on mixed samples and Diffuse Reflectance IR Fourier Transform (DRIFT) on unmixed samples. IR spectra are collected in either MIR or NIR regions. However, the preprocessing of IR spectra, the choice of the spectral band and the combination of MIR-NIR information are important factors that could substantially influence analyses. This study investigates these factors while attempting to retrieve three different genotypes of maize roots via a Fuzzy C-Mean (FCM) classification of IR spectra. A bootstrapping procedure is used as the number of samples is limited. Results show that KBr spectroscopy is better than DRIFT spectroscopy for MIR region; MIR provides equivalent information as NIR for DRIFT spectroscopy; combination of MIR-NIR information gives preprocessing independent results. Several distances are tested in FCM classification. The city bloc distance gives optimal results compared with Euclidean, Chebyshev, correlation and diagonal distance.","PeriodicalId":421311,"journal":{"name":"The Third International Conference on e-Technologies and Networks for Development (ICeND2014)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123715234","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}

DC motors are configured across a large range of powers and different levels of speed. The simple techniques for controlling them, such as pulse width modulation, and the high performance of the DC motors functioning will yield to an increasing growth of the applications number and their varieties in the future. On the other hand, wireless communication is widely adopted in communication and information interchange, particularly with the spread use of cell phones. This article presents a wireless DC motor speed-control system by using PIC 16F877A microcontroller. An electronic circuit is coupled to the motor to provide the control-speed signal serially from distant microcontroller. A control panel is designed as an interface for the user to select the appropriate speed. The used commands are sent wirelessly to the control circuit driver. The microcontroller of this circuit regulates the DC motor as required using the pulse width modulation technique. Our approach is achieved by implementing a hardware prototype system constituted of two DC motors of a toy car. Total control and performing regulation are observed.","PeriodicalId":421311,"journal":{"name":"The Third International Conference on e-Technologies and Networks for Development (ICeND2014)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128746618","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}

One of the most basic parameters for network structures is the degrees of nodes and their distribution. Depending on the type of degree distribution (Poisson, power-law, exponential, etc.), various types of network structures are formed with varying disease outbreaks. Behavior of two competing diseases on a contact network of individuals is most affected by this parameter of degree distribution. In this article, the spreading process of two competing diseases and their impact on each other is presented using numerical simulations and analytical results on various network structures by MATLAB software. For each disease to be transferred from a person to another, it needs to have transmissibility greater than a threshold, which is called the epidemic threshold. Obtained results and patterns from the analysis are helpful for the intermediation in the case of two competing diseases and can help eliminate their outbreaks.","PeriodicalId":421311,"journal":{"name":"The Third International Conference on e-Technologies and Networks for Development (ICeND2014)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122263121","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}
