A combination method is presented to estimate the unknown pseudo-noise (PN) spreading sequence for direct sequence spreading spectrum (DS-SS) signals in frequency selective fading channel. Performance of traditional blind estimator based on eigenanalysis techniques shows significant performance degradation when directly employed in multipath fading environment. Borrowing blind channel estimation and equalization ideas, we provide two methods to mitigate the effect of channel-induced distortion. Eigenanalysis method is then exploited to estimate the PN code. Some illustrative simulations are presented for the combined method and the experimental results are analyzed. © 2008 IEEE.

Automatic language identification (LID) is a topic of great significance in areas of intelligent and security, where the language identities of any related materials need to be identified before any information can be processed. When the recognition elements of any content is dynamic and obtained directly from written text, the language associated with each grammar item has to be identified using that text. Many methods have been proposed in the literature are focusing on Roman and Asian languages. This paper describes text-based language identification approaches on Arabic script. Two different approaches have been compared. The decision trees method commonly used in many application domain is firstly reviewed. We also applied a simple method for language identification that is based on Adaptive Resonance Learning (ART) neural network. The experimented result shows that the decision tree model achieved highest accuracy than ARTMAP model. However, decision tree model may not reliable if the language used extends to others Arabic script compared to ARTMAP model. It is assumed that hybrid of both models will perform better and merit for further development. © 2007 IEEE.

The traffic data is increasing day by day. Data produced by traffic sensors, GPS equipped vehicles;loop detectors are used in intelligent transport systems. These data may include traffic volume, speed, density, local events, geospatial data, accident information and weather data. The collected data can be used in predicting the traffic flow, speed, congestion prediction. The more accurate prediction of congestion can increase the capacity of the road. In this paper, a review about congestion prediction is done with deep learning algorithms, metrics for classification and congestion. © Grenze Scientific Society, 2022.

Manufacturing of 3D stacked IC chips has became feasible recently. But testing of these 3D ICs is becoming important in the semiconductor industry. Now a days also embedded core based 3D ICs are equally popular. Hence the increased complexity in the chips becomes a constraint for the test engineers. This paper addresses a 1500-style wrapper optimization in 3D ICs based on Through Silicon Vias (TSVs) for vertical interconnects. This work minimizes scan test time with the optimum number of TSVs available for testing. The results are presented based on the ITC'02 SOC test benchmarks. The simulation results show that small number of TSVs are sufficient to test the embedded cores in the SOC. © 2010 IEEE.

Classification models can be learned from complicated multivariate temporal data and this is a topic we investigate in electronic health record systems. The difficulty is to come up with a collection of attributes that accurately reflect the data's temporal nature. Using temporal abstractions and pattern mining, we extract the classification features from the data. There are frequently a lot of temporal patterns that aren't related to the classification job that are returned by temporal pattern mining. © 2023 IEEE.

In metal cutting operations, tool wear could result in higher energy utilization, excessive tool vibration, and deteriorated surface finish quality. Therefore, tool wear monitoring is critical to enhance manufacturing productivity and quality. This study proposes a new approach for monitoring and classification of tool wear with 192 data sets of turning experimental tests at different cooling approaches. The Daubechies wavelet transform is used to state the level of flank wear at different cooling approaches. The acquired vibration signals were processed in both the time and frequency domain with various features extracted. An artificial neural network (ANN) model was applied to detect the flank wear at dry, flood, and minimum quantity lubrication(MQL) cooling states. The results confirmed the ability of the monitoring system to detect the flank wear of the cutting insert by utilizing the tool vibration signals. © 2024 IEEE.

This paper proposes a novel channel estimation method for TD-HSPA system in rapidly time-varying environments. We use a linear prediction model to depict the channel impulse response within a timeslot, then a least square (LS) and a minimum mean-square error (MMSE) estimator are deduced respectively based on some statistical characteristics of the channel. We further provide an approach to employ the proposed LS/MMSE method in downlink. As is proved by the simulations, the new estimation method outperforms other existing algorithms a lot. It's also important to point out that the proposed method is both robust and computationally efficient. © 2011 IEEE.

This paper discusses the application and the effect of the electric surge protection device (SPD) in the power line communication channel. The comparative analysis of the effect is carried out based on the performance of the power line communication (PLC) system. The SPDs used for the laboratory experiment are categorized into different types of classes depending on the surge protection level. Various combinations of the SPD with different classes are tested to accommodate the real field environment. The transmission line length is also considered as a test parameter. The OFDM based data transmission system is assumed for the data throughput performance test for given channel conditions. Experiment results show that the effects on the PLC network vary depending on classes and locations of the installed SPDs as well as the channel length between the transmitter and the receiver end. The result confirms that systematic SPD installation requirements should be set up to maintain the stable performance of the data transmission system and the SPDs which coexist in the same power transmission lines.

Metamaterial absorbers are an advancement in material science as they provide more advantages in comparison to conventional materials. Achieving miniaturization with a multilayered structure is the primary challenge here. In this study, a novel metamaterial absorber design is proposed for microwave application. The proposed design is shaped as a squad of four segments where each segment contains an octagonal split ring and a central ring. The multi-layered design of the absorber helps to secure a high absorption rate. An extensive range of research is done to determine particular measurement units, and geometric shapes with the help of CST Studio Suit 2019. Here both ground and patch are designed using copper and the separator is designed with Roger. Moreover, the thickness of the absorber is only 3.4 mm which ensures its ultra-thin and lightweight nature. With an elaborated numerical analysis, it has been shown that the proposed absorber provides 90% to 99% absorption at the C, X, and K bands. Moreover, a concise computational analysis is accomplished with FR4 lossy, Rogers RT6010LM lossy, and Rogers RT5870LM lossy as dielectric constant. The key contribution of this research is the high absorption rate, coupled with minimal thickness and simple structure. © 2024 IEEE.
