Enhanced Online Question Bank Management System For Efficient Of Exam Paper

Online exam question bank system bank will be used to facilitate the implementation and monitoring of development activities in polytechnics final exam item. Some activities and information systems are as follows, the formulation item final exam, review item final exam, fitting item final exam, purification item final examination, revision of the final draft (proof read) item final exam, usage data item final exam, information final examination items specification table (Feist). For developing and using online exam question bank system bank could facilitate the drafting process, facilitate the review process of the draft items and simplify the process of monitoring items for centralized final exams. In addition, operating costs, costing the drafting of the final exam questions can be reduced by almost RM1,000,000. Overall, the benefits are longer term projects, analysis of findings of data quality questions can be implemented, standardizing the format of the question paper and the front cover final exam questions, reduce work processes and document monitoring at the polytechnic. , Simplifies the process of analyzing the final examination questions by the Polytechnic Examinations Officer. As such a study should be conducted to identify methods of development, the parameters to be taken into account, consumption and use of appropriate technology in the construction of this system

Prostate cancer cell inhibition by ethanolic fraction of Ficus deltoidea var. kunstleri

Ficus deltoidea or also known as ‘Mas Cotek’ belongs to the Moraceae family. It is widely used by practitioners for post-natal treatment, anti-diabetes and anti-hypertension. Study has documented that they were at least 13 different varieties of F. deltoidea. However, the present study only accounted for three varieties of F. deltoidea for the evaluation of their antioxidant and anti-cancer effects against prostate cancer cell. The varieties include F. deltoidea var. angustifolia, F. deltoidea var. deltoidea and F. deltoidea var. kunstleri. The study was divided into two parts whereby the best variety and the potent fraction were determined. The aqueous extract of F. deltoidea var. kunstleri was selected for fractionation using solid phase extraction as it demonstrated the highest content of phenolic, flavonoid, vitexin as well as lowest concentration to inhibit radical scavenging activity, IC50 0.043 mg/mL. Moreover, cytotoxicity study through the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay also demonstrated that F. deltoidea var. kunstleri had the lowest IC50 of 93.11 ?g/mL. The fractionation was accomplished using mixture of different ratio of ethanol/water. Eluent 1 (EL 1) was fractionated using 20% of ethanol/water exhibited the highest polyphenol contents and the highest inhibition against prostate cancer at 100 ?g/mL (45.45%). The mechanism involved in the reduce cell viability exerted by F. deltoidea var. kunstleri and EL 1 was due to apoptosis and it was confirmed using flow cytometry. In the event of apoptosis, cells treated with F. deltoidea var. kunstleri and EL 1 undergoes morphological changes that comprised of cell condensation, fragmentation and necrosis. Moreover, the Fourier transform infrared spectroscopy - attenuated total reflectance analysis showed that EL 1 contained other chemical compounds that created a synergistic effect toward cells inhibition. Positive correlations were also established among antioxidant and anti-cancer activities of varieties and fractions. Therefore, these results suggested that antioxidant activity of F. deltoidea var. kunstleri and its fraction, EL 1 with the presence of polyphenols and vitexin can potentially be used as an anti-cancer agent especially for prostate cancer

Evaluating the Thermal Condition of Electrical Equipment via IRT Image Analysis

The integrity of electrical power equipment is of paramount importance when itsupplies electricity throughout a facility. However, the reliability of the equipments will degraded after sometime, and appropriate maintenance has to be taken accordingly to avoid future faults. Infrared thermography (IRT) image analysis is a commonly used technique for diagnosing the reliability of electrical equipments. Conventionally, the analysis of infrared image is done manually and takes very long time for further analysis. This paper proposes an automatic thermal fault detection and classification system for evaluating thecondition of electrical equipment by analyzing its infrared image. First, the image is segmented to find the target region of interest (ROI). The detected regions which have the same region properties are grouped together in order to remove the unwanted regions. Finally, statistical features from each detected region are extracted and classified using the support vector machine (SVM) algorithm. The thermal condition of electrical equipments is evaluated based on qualitative measurement technique. The experimental result shows that the proposed system can detect and classify the thermal condition of electrical equipments

Development of Smart System for Renewable Energy Hybrid Power System Base on SCADA

This paper presents the development of smart energy monitoring and control system for Renewable Energy Hybrid Power Generation System (REHPGS) using SCADA. REHPGS model consists of photovoltaic, wind and gen-set system. SCADA is used to monitor and control the operation of Hybrid Power System (HPS) in real time. This paper planned a concept of smart grid by VisconDua Remote Terminal Unit (RTU)-IO Module. The RTU is responsible to collect information from power HPS plant. SCADA Expert controller is introduced to automatically control renewable energy sources. The monitoring and control system of REHPGS operated in real time and can perform under various operating conditions. The HPS plant will be fully automated, which mean the power plant would rely on the SCADA system on all its operations. Results show that the proposed system has the capability to monitor and optimize the output power generation of REHPG

Thermal Imaging for Enhancing Inspection Reliability: Detection and Characterization

Reliable performance of an equipment or structure depends on pre-service quality and in- service degradation of the equipment or structure under operating conditions. The role of non-destructive testing (NDT) is to ensure integrity, and in turn, reliability of equipment or structure. Besides, NDT can also monitor in-service degradation and to avoid premature failure of the equipments/structures and prevent accidents as well as save human life. Up to now, NDT has been used in various fields of applications such as the inspection o

Development of improvement initiative selection framework for business excellence

Usually, the organization could define hundreds of action plan by implementing above improvement initiative. Challenge on the organization nowadays was limited capacity of time, resource and money in order to improve on current business. Thus, selection on the right continuous improvement and deployment the strategy will be important things to achieve organization objective. The objectives of the study were to propose selection continuous improvement initiative framework for organization guidance. Framework was propose based on extensive literature review, linear regression model was used to identify opportunity and Analytical Hierarchy Process (AHP) was used in order to prioritize the initiative. Outcomes of this study to comply with ISO 9001 2015 under Section 9.3 and Section 10.3 requirement. Case study on proposed framework had been perform in Flexible Pipe Manufacturing unit. Finally, the proposed framework was validated through structure survey and the result shows that proposed framework was significant to improve current key performance indicator and meet expectation of the organization
