Using FPGA Design and HIL Algorithm Simulation to Control Visual Servoing

10.11591/ijres.v6.i2.pp111-119
Lway Faisal Abdulrazak , Zaid A. Aljawary
This is a novel research paper provides an optimal solution for object tracking using visual servoing control system with programmable gate array technology to realize the visual controller. The controller takes in account the robot dynamics to generate the joint torques directly for performing the tasks related to object tracking using visual servoing. Also, the notion of dynamic perceptibility provides the capability of the designed system to track desired objects employing direct visual servoing technique. This idea is assimilated in the suggested controller and realized in the programmable gate array. Additionally, this paper grants an ideal control framework for direct visual servoing robots that incorporates dynamic perceptibility features. With the aim of evaluating the proposed FPGA based architecture, the control algorithm is applied to Hardware-in-the-loop simulation (HIL) set up of three degrees of freedom rigid robotic manipulator with three links. Furthermore, different investigations are performed to demonstrate the behavior of the proposed system when a trajectory adjacent to a singularity is attained.

Across all the regions in the Philippines, the National Capital Region (NCR) got the highest percentage (37%) for HIV newly diagnosed cases based from  the July-August 2017 HIV/AIDS and ART Registry of the Philippines’ report. The National HIV, AIDS, and STI Prevention and Control Program (NASPCP) of the Department of Health (DOH) lead the different health services in the prevention of HIV transmission. Anchored with the NASPCP, different HIV programs of DOH’s selected partner institutions and organizations within NCR continuously exist. However, due to the increase on the number of newly diagnosed HIV cases in the country, ensuring its sustainability through assessing the different domains of their program was in need to be studied. This article was based from an undergraduate thesis study which aimed to assess the sustainability capacity of HIV programs among DOH’s selected partner institutions and organizations within NCR, Philippines, scoping the eight domains specifically the environmental support, funding stability, partnerships, organizational capacity, program evaluation, program adaptation, communications, and strategic planning. The study used a quantitative approach; 17 government institutions specifically city health offices and 13 non-government HIV-related organizations for a total of 30 respondents. Survey method was utilized using the standardized Program Sustainability Assessment Tool adapted from the Washington University in St. Louis. Based from the results and findings of the study, generally, all the domains were leaning either in great and greater extent as verbally interpreted. From the conclusion, all the domains of the HIV programs of the respondents were sustainable. However, the study recommended to the DOH and all the HIV program implementers the developed and proposed narrative-type action plan. By that means, future researchers can assess again and see if the NCR achieved the vision of the Health Sector Plan for HIV and STI for the year 2015-2020 to have zero new infections, zero discrimination, and zero AIDS-related deaths.

Infancy is a golden and critical period in the cycle of life. In this period, an infant that is not provided with exclusive breastfeeding has 14 times higher risk to death compared with an infant that is provided with exclusive breastfeeding. Malnutrition in the first year causes reduced brain cells up to 15-20% which leads to impaired growth and development of infant. Exclusive breastfeeding can fulfill the need for nutrients within the first 6 months of life. The objective of this study was to analyze the difference in growth and development of infants at the age of 6-12 months based on breastfeeding in the working area of Puskesmas Perawatan Ngkeran, Aceh Tenggara Regency. This is used comparative analytical resaerch with cross sectional design. The sample was 124 infants consisting of 62 infants with exclusive breastfeeding and 62 non exclusive breastfeeding, taken by purposive sampling. The data were collected by using questionnaires through interviews, measurement and observation. They were analyzed using chi square and logistic regression testing for confounding check. The results showed that there was a significant difference in growth and development of infants based on breastfeeding (p value=0.000) with prevalence ratio (PR)=4.167 (95%CI: 1.867-9.301), which indicated that the infant who did not get exclusive breastfeeding had 4.167 times higher risk to experience bad growth and development. Based on the examination of confounding variable found that food supplementation was the variable with the risk that influences infant’s growth and development. Mothers are expected to practice exclusive breastfeeding, health practitioners are suggested to conduct more counseling of exclusive breastfeeding for pregnant mothers, to have early breastfeeding initiation, to create supporting groups of exclusive breastfeeding and to issue health policy of exclusive breastfeeding.

The prevalence of obesity among adolescent minority populations has been long recognized, but little research has been done on Native Americans adolescents. Using anthropometric measurements and dietary assessments, the findings within each study have shown to obtain baseline measures to determine the prevalence of obesity within the Sherman Indian High School’s Native American adolescent population. Data of each assessment appear to be of use for predicting obesity and creating effective future interventions. Compiling data using the Harvard School of Public Health Youth/Adolescent Questionnaire (HSPH YAQ), a semi-quantitative food frequency questionnaire allowed significant data to be found between normal and obese weight students. Utilizing each finding allows more effective ways of targeting and reversing the inclining rate of obesity among Native American adolescents. Results show that antioxidants being examined on such as vitamin E and lycopene are beneficial in lowering the obesity rate among Native American adolescents. Levels of fiber, thiamin and folate consumption was significantly lower among the obese population in Sherman Indian High School’s Native American adolescents. Moreover, dietary mineral intake was shown to be lower among obese Native American adolescents comparing with the normal weight group. The results suggested that dietary consumption of these nutrients might correlate and predict obesity and lead to the development of effective interventions for Native Americans. This study also found the effects of total fiber and vitamin B in diets with lifestyle intervention in prediabetic adults, showing that total fiber intake among the normal weight students is significantly higher than obese students, indicating that fiber and vitamin profile could be important determinants of the effect of dietary intervention.

Paraquat is the herbicide widely used at palm oil plantations, although usage it in some countries has been banned and restricted. Paraquat spraying was not appropriate procedure could be polluted the environment and lead to health disorders workers. Paraquat could enter the body through inhalation, dermal and ingestion, one of frequent routes through inhalation during spraying weeds in plantation areas. This study aimed was to analyze potential inhalation dose and Risk Quotient to workers at palm oil plantation. This research was a descriptive study with cross sectional design and analysis of environmental health risk methods. Airborne Paraquat residue was collected from 8 workers with occupational activity as a supervisor and sprayer. Airborne Paraquat residue was measured for 25 minutes during spraying by using personal air sampler at worker’s breathing zone. Airborne Paraquat residue was detected by High Performance Liquid Chromatography (HPLC) with NIOSH 5003 methods. The average of airborne Paraquat residue was 0.0125 mg/m3, it values was less than the Threshold Limit Value (0.05 mg/m3) of American Conference of Government Industrial Hygienists, but the average of potential inhalation dose was 0.001 mg/kg/day for worker’s weight 55 kg, it was value higher than Acceptable Operator Exposure Limit (0.0005 mg/kg/day) and the calculation of Risk Quotient (RQ) was more than 1, it conditions was unacceptable for workers. Although, airborne Paraquat residue were safe, but potential inhalation dose and Risk Quotient (RQ) were unsafe for workers, cause it can be lead to lung function disorders. Therefore, for further studies it was necessary to assess the lung function of workers and the use of personal protective equipment must be completely and standard.

Nowadays, in most of the modern database applications, lots of critical queries and tasks cannot be completely addressed by machine. Crowd-sourcing database has become a new paradigm for harness human cognitive abilities to process these computer hard tasks. In particular, those problems  that are difficult for machines but easier for humans can be solved better than ever, such as entity resolution, fuzzy matching for predicates and joins, and image recognition. Additionally, crowd-sourcing database allows performing database operators on incomplete data as human workers can be involved to provide estimated values during run-time. Skyline queries which received formidable attention by database community in the last decade, and exploited in a variety of applications such as multi-criteria decision making and decision support systems. Various works have been accomplished address the issues of skyline query in crowd-sourcing database. This includes a database with full and partial complete data. However, we argue that processing skyline queries with partial incomplete data in crowd-sourcing database has not received an appropriate attention. Therefore, an efficient approach processing skyline queries with partial incomplete data in crowd-sourcing database is needed. This paper attempts to present an efficient model tackling the issue of processing skyline queries in incomplete crowd-sourcing database. The main idea of the proposed model is exploiting the available data in the database to estimate the missing values. Besides, the model tries to explore the crowd-sourced database in order to provide more accurate results, when local database failed to provide precise values. In order to ensure high quality result could be obtained, certain factors should be considered for worker selection to carry out the task such as workers quality and the monetary cost. Other critical factors should be considered such as time latency to generate the results.

Signal Strength based Self Reconfiguration to Ensure Reliability in Wireless Sensor Networks

10.11591/ijeecs.v10.i2.pp725-732
M.A. Manivasagam , T.V Ananthan
Providing reliability in Wireless sensor networks is considered to be a challenging task, due to the limited capabilities in terms of energy, power and memory. The applications of these systems run in sensors with low level programming abstractions, limited capabilities and routing protocols. In this paper, we propose a strategy to adjust radios in the sensor network depending on the signal strength of the neighboring nodes to ensure reliability using self reconfiguration (S2R2). Redundancy-based reliability is achieved by performing encoding/decoding either at the source and the destination node or each pair of communicating sensor nodes from the source to the destination. Along with the reliability, the link and the stability of the link are checked. The stability of the route makes the route a valid one to send data. Simulation analysis shows that the proposed mechanism performs better in terms of stability and reliability compared to the existing mechanism

10.11591/ijeecs.v10.i2.pp426-435
Sharin Ab Ghani , Zulkarnain Ahmad Noorden , Nor Asiah Muhamad , Hidayat Zainuddin , Mohd Aizam Talib
Power transformers are the backbone of electricity transmission and distribution systems throughout the world. The price of power transformers is exorbitant (costing millions of dollars per unit) and therefore, frequent maintenance is necessary to ensure that these systems are highly reliable during their operation. The service life of mineral insulating oils is typically 30 to 40 years for power transformer applications. However, all insulating oils (regardless of their type) are subjected to thermal, electrical and chemical degradation, which will deteriorate the oil-paper insulating system and consequently reduce the capability of the oil as an electrical insulator. For these reasons, service-aged insulating oils are treated by two types of processes (i.e. reclamation and reconditioning) in order to prolong the service life of these oils. Reclamation (regeneration) is used to treat insulating oils with high levels of acidity and sludge. In this paper, a brief review on the reclamation technologies used to treat service-aged insulating oils is presented, covering various aspects such as the standard test methods that need to be complied with, the types of adsorbents used to reduce acidity and sludge of the used insulating oils, as well as the findings of several key studies related to the evaluation of the effectiveness of the reclamation process. This review will indeed benefit researchers and practitioners in this field since it provides an overall picture of the recent progress in reclamation technologies for service-aged transformer insulating oils
