The precise indoor tracking system using Xbee signal strength protocol has become a potential research to the WSN applications. The main aspects for the success tracking system is accuracy performance based on location estimation. The improvement of location estimation is complicated issue, especially using RSSI with low accuracy due to the signal attenuation from multipath effect at indoor propagation. Hence, many existing research typically focused on specific methods for providing improvement schemes at tracking system area. Then, we propose hybrid filter schemes, including extended gradient filter (EGF) for filtering noise signal based distance modification, and modified extended Kalman filter (MIEKF) will be combined with trilateration for filtering the error position estimation. Using mobile cooperative tracking scenario refers to our previous work, the proposed hybrid filter scheme which is called modified iterated extended gradient Kalman filter (MIEGKF) can optimize the error estimation around 41.28% reduction with 0.63 meters MSE (mean square error) value.

D C Vinutha , G.T Raju
MapReduce is the preferred computing framework used in large data analysis and processing applications. Hadoop is a widely used MapReduce framework across different community due to its open source nature. Cloud service provider such as Microsoft azure HDInsight offers resources to its customer and only pays for their use. However, the critical challenges of cloud service provider is to meet user task Service level agreement (SLA) requirement (task deadline). Currently, the onus is on client to compute the amount of resource required to run a job on cloud. This work present a novel makespan model for Hadoop MapReduce framework namely OHMR (Optimized Hadoop MapReduce) to process data in real-time and utilize system resource efficiently. The OHMR present accurate model to compute job makespan time and also present a model to provision the amount of cloud resource required to meet task deadline. The OHMR first build a profile for each job and computes makespan time of job using greedy approach. Furthermore, to provision amount of resource required to meet task deadline Lagrange Multipliers technique is applied. Experiment are conducted on Microsoft Azure HDInsight cloud platform considering different application such as text computing and bioinformatics application to evaluate performance of OHMR of over existing model shows significant performance improvement in terms of computation time. Experiment are conducted on Microsoft Azure HDInsight cloud. Overall good correlation is reported between practical makespan values and theoretical makespan values.

Optimization Based Liver Contour Extraction of Abdominal CT Images

10.11591/ijece.v8i6.pp5061-5070
Jayanthi Muthuswamy , B Kanmani
This paper introduces computer aided analysis system for diagnosis of liver abnormality in abdominal CT images. Segmenting the liver and visualizing the region of interest is a most challenging task in the field of cancer imaging, due to small observable changes between healthy and unhealthy liver. In this paper, hybrid approach for automatic extraction of liver contour is proposed. To obtain optimal threshold, the proposed work integrates segmentation method with optimization technique in order to provide better accuracy. This method uses bilateral filter for preprocessing and Fuzzy C means clustering (FCM) for segmentation. Mean Grey Wolf Optimization technique (mGWO) has been used to get the optimal threshold. This threshold is used for segmenting the region of interest. From the segmented output, largest connected region are identified using Label Connected Component (LCC) algorithm. The effectiveness of proposed method is quantitatively evaluated by comparing with ground truth obtained from radiologists. The performance criteria like dice coefficient, true positive error and misclassification rate are taken for evaluation.

Nurul Rezki Anisa , Kadek Ayu Erika , Rini Rachmawaty
Cancer has many side effects on patient’s physic and mostly on mental which may affect on their quality of life. Physically most patients feel fatigue, insomnia, anorexia, nausea, and vomit while mentally they feel emotional disturbances such as anxiety, stress, or depression. One of the methods to that appropriate to overcome both of the conditions is spiritual care. Many research found that because spiritual care associated with better wellbeing, less emotional disturbance, less substance abuse, greater social support, better health behaviours, so it has impact to longer survival periods. This research aimed to investigate nurse’s spiritual care competencies to patients with end stage cancer. This was descriptive study design employed Spiritual Care Competencies Scale (SCCS) instrument. A total sampling of 24 nurses working in Oncology department in Dr. Wahidin Sudirohusodo Hospital were recruited. This research found that there are 12 nurses (50 %) that work in oncology department have low competencies of spiritual care. Involving spiritual care is associated with better wellbeing and longer survival periods. Therefore, it is necessary to increase the competence of nurses on spiritual care in meeting the spiritual needs of patients with end stage breast cancer. A training of spiritual care can be an alternative for nurses to improve spiritual care in hospitals.

A Novel Multipath Routing Ring Protocol Adapted for WMSN

10.11591/ijeecs.v12.i3.pp1045-1053
Bennani Mohamed Taj , Mhamed M. Ait Kbir
In this paper an enhanced protocol of multipath routing ring that is suitable for transferring images by making many upgrades. First, instead of using propagation between the layers, we use certain parameters such distance and delay to pick the next node of the lower layer. Then, we used an heterogeneous network, including sensors (capture and send images) and connectors (serve as a bridge to the sink). Finally, we used  the pyramid decomposition technique. To avoid congestion, we adjust  the number of levels based on the state of the network. To verify our protocol, we used Castalia simulator to simulate the real transmission conditions. Then, we compared it with GPSR protocol and the original Multipath routing ring protocol. Our proposed protocol proves its efficiency by transferring more images with better quality (PSNR) and consuming less energy compared to other protocols.

Wavelet transform (WT) has recently drawn the attention of the researchers due to its potential in electromyography (EMG) recognition system. However, the optimal mother wavelet selection remains a challenge to the application of WT in EMG signal processing. This paper presents a detail study for different mother wavelet function in discrete wavelet transform (DWT) and continuous wavelet transform (CWT). Additionally, the performance of different mother wavelet in DWT and CWT at different decomposition level and scale are also investigated. The mean absolute value (MAV) and wavelength (WL) features are extracted from each CWT and reconstructed DWT wavelet coefficient. A popular machine learning method, support vector machine (SVM) is employed to classify the different types of hand movements. The results showed that the most suitable mother wavelet in CWT are Mexican hat and Symlet 6 at scale 16 and 32, respectively. On the other hand, Symlet 4 and Daubechies 4 at the second decomposition level are found to be the optimal wavelet in DWT. From the analysis, we deduced that Symlet 4 at the second decomposition level in DWT is the most suitable mother wavelet for accurate classification of EMG signals of different hand movements.

Gichogo Agnes Wangeci , David Macharia
Globally, cervical cancer continues to be a major cause of mortality and morbidity among women with developing countries accounting for more than 86% of the deaths from the disease. In Kenya, cervical cancer ranks as the second most frequent cancer among women: regrettably, with 80% of the cases presented during the late stages of the disease when the scope of successful treatment is limited. An opportunity to prevent occurrence of cervical cancer exists through cervical cancer screening for early detection and treatment of precancerous lesions before these develop to cancer. However, only a negligible proportion of women benefit from cervical cancer screening services in developing countries, including Kenya. The purpose of this descriptive survey study was to determine the factors influencing utilization of cervical cancer screening services; and focused on the women seeking maternal and family planning services at Central Provincial General Hospital, Kenya. The study established that, as in most developing countries, utilization of cervical cancer screening services was low, regardless of the women’s education level, autonomy in decision making and even good family support. The low level of awareness on the need for screening services and the long waiting time at the clinic for those seeking the services were identified as the two key issues that negatively influenced the utilization of the screening services, It is therefore recommended that the Ministry of Health and other agencies, including individuals of good will, collaborate in designing and implementing awareness campaigns through the media and other appropriate avenues, including one-to-one encounters, targeting both men and women in the communities. It is also recommended that the male partners support their women in accessing this vital life-saving service.

A ventilation system comprising a ventilator or fan to inhale fresh air from environment surrounding enters the cabin of a car where at the same time exhale the hot air to the outside. This invention system is using solar power integrate with the ventilation system in order to stabilize the thermal condition inside the car during sunny day. The solar power is chosen as it is reasonable due to its limitless and environmental friendly source just like mentioned in the previous objective of the project. In addition, a rechargeable battery is used to power the ventilator in the absence of the alternative energy during cloudy day or has obstacle like being shaded by buildings, trees and others. It is just like an extra supply during emergency case. This may prevent the lack of power energy supply for the system. A heat sensor is used as to detect targeted (high temperature) and desired temperature (drop temperature) inside the car. It is operatively connected to a logic circuit to measure environmental factor, wherein the controller (PIC Microcontroller) utilizes the measured environmental condition to allow the power supply to activate or deactivate the ventilator.

School youth in many African countries face a range of non-infectious health risks, in addition to the infectious disease burden typical in resource-limited settings. We examined self-reported health behaviors associated with suicide ideation, school absenteeism and physical violence among secondary school students in Kampala, Uganda. We conducted a cross-sectional three-stage cluster-based survey among students aged >=15 years, and/or enrolled in forms 3–6 (grades 9-12) in 54 secondary schools in Kampala. Interview data were collected with a standardised electronic questionnaire through computer-assisted self-interviewing and results were weighted for sample design and non-response. Pearson’s chi-square and logistic regression methods were used for bivariate and multivariate analysis respectively. Bullying among female respondents was positively associated with suicide ideation (aOR=1.73). In multivariate analysis, suicidal ideation was positively associated with a lifetime exposure to illicit drug use (aOR=1.76), serious injury (aOR=1.67) or school absenteeism (aOR=1.46). School absenteeism was positively associated with serious injury (aOR=1.59), history of alcohol consumption (aOR=1.55), bullying (aOR=1.52) and suicide ideation (aOR=1.45). Serious injury (aOR=2.89), a life-time history of illicit drug use (aOR=2.65), recent history of having been bullied (aOR=2.38), physical activity (aOR=2.12), suicide ideation (aOR=1.58), school absenteeism (aOR=1.57) were associated with having been engaged in physical violence. Bullying, serious injury and illicit drug use were associated with suicidal ideation, school absenteeism and physical violence. Concerted efforts should be considered by education authorities, parents and the community to tackle these risky behaviors.

PAPR Reduction at Large Multi-User-MIMO-OFDM using Adaptive Data Detection Algorithm

10.11591/ijeecs.v12.i3.pp1071-1080
N Praba , K. M. Ravikumar
Wireless communication in present era contains large-scale MIMO network architecture that need to deliver an optimize-QoS to multi-user (MU). The optimize data rate transmission in massive MU-MIMO wireless systems is one of the most difficult task due to the extremely high implementation complexity. The practical wireless system channels generally exhibits the PAPR and frequency selective fading, it is also necessary to have a precoding solution in PAPR for the selected desirable channels. A solution for the designed problem of a noble error-correcting code for OFDM process with a low PAPR, in the case of impulse noise should be considered. In this paper, Adaptive-Data-detection (ADD) algorithm is proposed to obtain lower-complexity data-detection that corresponds to high throughput design and impulse noise removal for large MUI-MIMO wireless systems by the OFDM modulation technique. That contains some steps such as; initialization, pre-processing and equalization steps in order to get no performance loss and to minimalize the recurrent amount at each iterations during operation. In order to use simplify model, here we assume suitably perfect synchronization, large cyclic prefix and perfect-CSI (channel-state-information) which has been developed through the pilot depended training. Simulation results analysis show the proposed method substantial improvement over the existing algorithm in terms of both ‘Error-rate’ minimization and PAPR reduction.

In this paper, a novel microwave sensor with high Q-factor for oil sensing is analyzed and investigated. The new design is based on a gap waveguide cavity resonator (GWCR). To characterize and evaluate the sample, the oil under tested (OUT) is injected into a Teflon tube, which is passing through the microfluidic channel that is located in the middle of the cavity where the electric field concentrates. The results show that the proposed sensor has a high Q-factor of 4832. Moreover, the proposed design has the ability to sense and detect different types of oils with a small variation of permittivities such as Fish oil, Coconut oil, Olive oil, Linseed oil and Castor oil. The permittivity equation is extracted using the polynomial fitting method to define unknown dielectric properties of the OUT. The results show that the evaluated permittivity using the proposed sensor has a good agreement with the ideal permittivity. Therefore, the proposed sensor is a good candidate for oil processing in food industries.
