In this paper, we propose an adaptive framework for the variable power of the fractional least mean square (FLMS) algorithm. The proposed algorithm named as robust variable power FLMS (RVP-FLMS) dynamically adapts the fractional power of the FLMS to achieve high convergence rate with low steady state error. For the evaluation purpose, the problems of system identification and channel equalization are considered. The experiments clearly show that the proposed approach achieves better convergence rate and lower steady-state error compared to the FLMS. The MATLAB code for the related simulation is available online at https://goo.gl/dGTGmP.

Electric motors with more than three phases have many advantages comparing to ordinary three-phase motor. For this reason it is natural to pay attention to them and to work on advanced control methods. Control algorithms development requires to operate with the model of motor. This paper presents the modeling concept of the nine-phase permanent magnet synchronous motor (PMSM) in three times three-phase arrangement fed by nine-phase voltage source inverter (VSI). Magnetic interaction between phases and phase groups had to be taken into account. The paper also provides relationship between model parameters and real motor ones, depending on the windings configuration. It shows the comparison between the simulation and experimental results with real motor. Used method of motor parameters measurement and the subsequent conversion of these parameters into d-q coordinates is clarified in this paper.

Personality is described as a fairly fixed feature of an individual which indicates individual's preferences. Personality has been shown to be relevant to many types of interactions such as in predicting movie preferences, social relationships, personality and music, and correlation between personality and job performance. Predicting personality from social media become the current trend as the information extracted can be utilized to improve the users' experiences with various computerized interfaces. Thus, many algorithms have been performed to predict personality from social media. In this paper, we compared the performance of several classifiers provided in WEKA namely Bayes, Functions, Rules, Trees, and Meta in predicting student's personality. Based on adopted framework, the profile data of undergraduate students were extracted from Twitter, analyzed, and then classified in the automatic personality prediction. Four features with significant correlation from the profile data have been selected to map into Big Five personality model. Only extraversion dimension of the Big Five was considered in this study. A 10-fold cross validation was used to evaluate the classifiers. Several parameters that were observed in the performance of the classifiers are classification accuracy, F-measure, time taken to build the model, Kappa statistic, and training errors. Experimental evaluation demonstrated that OneR algorithm is the best classifier in terms of the accuracy, F-measure, and Kappa statistic.

Hand paralysis is typical disabilities resulting from stroke. Rehabilitation assists stroke survivors to gaining back to their normal life and accomplishing the best level of independence. Repetitive practice is imperative to improve grasping strength and retrain the brain motor skills. Thus, this paper proposes an instrumented glove utilizing flex sensors and force resistive sensors for post-stroke hand rehabilitation system. The flex sensors are used to measure flexion/extension of each finger, while force sensitive resistor (FSR) sensors is attached on each finger tips to measure the forces applied at the fingertips when an object is grasped. Analogue signals from the sensors are conveyed to PIC16F877A microcontrollers for data processing then transferred to a personal computer for monitoring and analysis process. The results are then documented for the purpose of post-processing and progressive status tracking. Preliminary experimental results involving squeezing a rubber ball shows the usefulness of the developed glove by demonstrating the relation of fingers flexion/extension with forces applied on each fingertip.

Uranium is a naturally occurring radioactive and toxic element. An increased prevalence of birth defects was allegedly reported in Iraq in the post 1991 Gulf War period, which was largely attributed to exposure to depleted Uranium used in the war. This study is done to determine the concentrations of Uranium radioactivity in maternal blood and umbilical cord blood samples after delivery in hospitals in governorates of Baghdad, Dhi-Qar and Basrah in Iraq. A number of 100 pregnant women were involved; consist of 53 women delivered with normal and alive infants and another 47 women delivered with abnormal and dead deformed infants. The CR-39 detector is used to determine the Uranium concentrations found in the blood samples of maternal blood and umbilical cord blood. Results show that mean Uranium concentration for maternal and umbilical cord blood samples of deformed and dead infants is nearly double than the value of normal and alive infants. The older pregnant women were found to have greater Uranium concentration compared to younger pregnant women. Among the selected 3 governorates, pregnant women in Basrah shows the highest Uranium concentration on maternal and umbilical cord blood samples. High Uranium concentrations found in maternal and umbilical cord blood samples have caused the increased rate of mortality on infant and children in Iraq. Thus, precautions and awareness should be taken up seriously in order to improve the health condition and well being of the maternal and children, and thus for future generations in Iraq.

Garbage decomposition that produces methane could be very dangerous if not detected properly. This study used methane gas sensor (MQ-4) to detect the presence of methane from the decomposition of fish guts waste. This study also compared different adsorbents such as charcoal, Sodium Bicarbonate and its combinations, their ability to adsorb methane in a specially designed garbage bin. Results showed that after five days of monitoring, all the three tested adsorbents showed reduction in the concentration of methane. However, Sodium Bicarbonate gives the highest percent of reduction at 13.16 %. Charcoal showed 0.53% methane reduction and the combination of the two adsorbent showed 9.22% reduction of methane concentration. In addition, the amount of adsorbent was also considered. Doubling its amount also doubles the amount of methane reduced. We therefore conclude that Sodium Bicarbonate is a possible alternative to reduce methane.

Supply chain integration (SCI) which is a supply chain management (SCM) activity is progressively playing a critical capacity in the organization. An efficient supply chain is the key determinant factor for any process industry to stay competitive. The study suggests that organizations are opting for integrated supply chain system for seamless information flow among the stakeholders without analyzing the degree of integration beneficial for supply chain efficiency (SCE). Using data, primarily from a large oil & gas industry in Malaysia that has an integrated environment, this research studied how SCI and selective disintegration (DIS) affects supply chain efficiency (SCE) and organization performance (PER). In particular, this research has examined the benefits of disintegration of selective business processes from core supply chain system, which in-turn improves the efficiency of the chain. The study has incorporated multiple data collection and analysis techniques, combining qualitative and quantitative approaches and partial least square (PLS) structural equation modeling (SEM) has been employed to test the theoretical framework and hypotheses. The findings reveal that, almost 59% of PER and 76% SCE is improved as a result of the DIS. The main managerial lesson is that, in contrast to what has been written in many books and popular publications, efficient supply chain system is a cycle of integration and selective disintegration.

This paper presents a Linear Parameter Varying (LPV) approach to model and control two-mass systems with backlash. The maximum amplitude of the backlash angle is assumed to be unknown and variable having no knowledge about the upper and lower bounds of it. Proper affine state space model together with the admissible variations of the LPV parameters is designed in order to realize a viable convex polytope. Utilizing H∞ LPV lemmas and theories lead to a set of Linear Matrix Inequalities (LMIs). By solving these LMIs, appropriate scheduled state feedback gains are obtained. The designed robust control strategy can easily handle the variations of the backlash angle and load disturbance torque. A simulated two-mass backlash system verifies the efficiency of the designed control law.

Normally the cooling box used for the delivery of a frozen foods cannot preserved the food temperature for a long time and may cause the food quality deteriorated. This work focuses on the mechanism on how to preserve food and to investigate the current requirements to provide optimum thermoelectric cooler for temperature range between 5°C to 15°C. The design process focuses on designing a combination of heat sink and motor fan on a thermoelectric cooler. These two devices determined the changes in the temperature range inside the cooler box. This cooling system used Thermoelectric Module (TEM) as an actuator and also as the cooling element in the cooling system. Here, the foods are kept inside within the range of desired temperature setting. The temperature sensor measures the temperature and sends the data to the Arduino microcontroller. The Arduino gives the signal based on the set point and regulate the desired temperature inside the refrigeration system whereas the relay module was used as an ON-OFF controller to control the desired temperature setting. Preliminary result showed that thermoelectric cooler can produce the desired temperature range with the help of heat sink and DC fan as part of the cooling element in the system.
