In this work an image processing system was developed to identify malaria parasites in thin blood smears and to classify them into one of the four different species of malaria. Many techniques were implemented in the preprocessing stage to enhance the images. In the first part of the system morphological processing is applied to extract the Red Blood Cells (RBC) from blood images. The developed algorithm picks the suspicious regions and detects the parasites in the images including the overlapped cells. Accordingly, the RBCs are classified into infected and non-infected cells and the number of RBCs in each image is calculated. The second part of the system uses the Normalized Cross-Correlation function to classify the parasite into one of the four species namely, Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale. Compared to manual results, the system achieved 95 % accuracy for detection and counting of RBCs and 100% for detection and classifying the parasite into one of its four types. © 2017 IEEE.

In this paper, DC motor speed is controlled using PID controller and fuzzy logic controller. PID controller requires a mathematical model of the system while fuzzy logic controller base on experience via rule-based knowledge. Design of fuzzy logic controller requires many design decisions, for example rule base and fuzzification. The FLC has two input, one of these inputs is the speed error and the second is the change in the speed error. There are 49 fuzzy rules which are designed for the fuzzy logic controller. The center of gravity method is used for the defuzzificztion. Fuzzy logic controller uses mamdani system which employs fuzzy sets in consequent part. PID controller chooses its parameters base on trial and error method. PID and FLC are investigated with the help of MATLAB/SIMULINK package program simulation. It is founded that FLC is more difficult in design comparing with PID controller, but it has an advance to be more suitable to satisfy non-linear characteristics of DC motor. The results shows that the fuzzy logic has minimum transient and steady state parameters, which shows that FLC is more efficiency and effectiveness than PID controller. © 2017 IEEE.

In brachytherapy treatment of cancer, multiple radioactive seeds are implanted inside the cancer tumor by a surgical needle, and the locations of the seeds are dependent on the accurate placement of the needle at desired position inside the patient body. Therefore, needle placement is very important for the effectiveness of brachytherapy treatment. In this work, we propose design of Fuzzy-PID control system for a 5-DOF surgical robot to make the needle follow the desired trajectory to the cancer tumor. Numerical simulation using MALAB is developed to show the effectiveness of the proposed control system. Comparative evaluation with respect to PID controller are presented to validate the controller design. The results presented emphasize that a satisfactory tracking precision could be achieved using the proposed control system. © 2017 IEEE.

Content-based image retrieval (CBIR) is a technique uses visual contents such as color, texture and shape to search images from large scale image databases according to users' interest. In a CBIR, visual image content is represented in form of image features, which are extracted automatically and there is no manual intervention, thus eliminating the dependency on humans in the feature extraction stage. Recent studies in CBIR get the similarity results and retrieve images based on one type of feature which are color, texture or shape. In this study authors proposed a fusion based retrieval model for merging results taken from color and texture image features based different fusion methods. After implementing our proposed retrieval model on Wang image dataset which widely used in CBIR, the results show that CombMEAN fusion approach has the best and high precision value and outperformed both individual color and texture retrieval model in both top10 and top20 retrieved images. © 2017 IEEE.

Background: It is known that any individual similarity measure will not always give the best recall of active molecule structure for all types of activity classes. Recently, the effectiveness of ligand-based virtual screening approaches can be enhanced by using data fusion. Data fusion can be implemented using two different approaches: group fusion and similarity fusion. Similarity fusion involves searching using multiple similarity measures. The similarity scores, or ranking, for each similarity measure are combined to obtain the final ranking of the compounds in the database. Results: The Condorcet fusion method was examined. This approach combines the outputs of similarity searches from eleven association and distance similarity coefficients, and then the winner measure for each class of molecules, based on Condorcet fusion, was chosen to be the best method of searching. The recall of retrieved active molecules at top 5% and significant test are used to evaluate our proposed method. The MDL drug data report (MDDR), maximum unbiased validation (MUV) and Directory of Useful Decoys (DUD) data sets were used for experiments and were represented by 2D fingerprints. Conclusions: Simulated virtual screening experiments with the standard two data sets show that the use of Condorcet fusion provides a very simple way of improving the ligand-based virtual screening, especially when the active molecules being sought have a lowest degree of structural heterogeneity. However, the effectiveness of the Condorcet fusion was increased slightly when structural sets of high diversity activities were being sought. © 2014 Ahmed et al.; licensee Chemistry Central Ltd.

Filtering of radar signals frequently takes place to realize a certain task, such as interference reduction or Doppler processing to remove clutter. However, in this paper a digital filter is proposed to be designed as a multifunction processor, achieving several sorts of signal processing within the same module. Processing is easily done in the baseband rather than in passband, for a moderately slow DSP processor. Hence, a lowpass filter will perform the task of rejection of the out-of-band interference. Higher SNR can be obtained to enhance the detection of targets inside noise if that filter is matched to the expected radar signal, even if it caused signal distortion. Doppler processing makes use of digital filters to cancel signals from fixed and slow targets. The proposed filter would be designed as an adaptive filter to follow interference and clutter changes, and eliminate blindness to some moving radar targets that arise in digital Doppler processing due to aliasing caused by targets of higher speeds. Matlab simulations are made to validate the idea and observe features and limitations of the proposed adaptive filter. Adaptive filter that is based on the least-mean-square algorithm is designed to achieve the best outcome. © 2013 IEEE.

Special technique is proposed for the design of soft modems that would be appropriate to transfer text messages at up to 300 bauds. Modulation scheme used is audio frequency shift keying, which is suitable for transport of text messages through the voice channel over HF and VHF radios. The soft modem is primarily designed to be implemented using low cost microcontrollers, and without the need of analog circuits such as active filters or a phase-locked loops. In addition to the physical layer, the proposed modem performs data link layer tasks such as framing and error detection and automatic request. Though synchronous transmission could be applied, asynchronous serial communication protocol is used to minimize design complexity, and be in essence to asynchronous FSK demodulation. The FSK modulation technique used is continuous phase FSK to eliminate phase jitters problem. Minimum shift keying can be applied, but with limitation for flexibility in changing baudrate and carriers frequencies. Proposed FSK demodulation is not a synchronous nor a PLL or a filter-based detector. Instead, a sort of frequency counter is proposed in this paper. Matlab simulations are made to validate the algorithm and observe features and limitations, such as the bit error rate and maximum bitrate. Later, the algorithm is examined by the aid of a code running on a virtual microcontroller, before being running on a real one. © 2013 IEEE.

During 4 months (November 2010-March 2011) of an outbreak of hepatitis E virus (HEV), 39 pregnant women presented at Port Sudan Hospital, Sudan, with various symptoms of viral hepatitis. The diagnosis of viral hepatitis was confirmed by serology using ELISA anti-HEV IgG and IgM. The mean (SD) maternal age and gestational age were 24·0 (4·2) years and 33·6 (3·7) weeks, respectively. Eight (20·5%) women were primigravidae. There were 11 (28·2%) maternal deaths, 14 (36·0%) intrauterine fetal deaths, and eight (20·5%) cases of postpartum haemorrhage. There were nine (23·0%) cases of preterm (<37 weeks of gestation) deliveries. Fulminant hepatitis with hepatic encephalopathy was the most common cause of death among these patients. Nine of these women died before delivery and the other two died immediately following the delivery due to severe haemorrhage. There were no significant differences in clinical and biochemical data between the women who died (11) and those who survived. © W. S. Maney & Son Ltd 2013.
