Region of interest extraction for biometric cryptosystem

Biometric technology is becoming more and more significant these days. Most of the application in store today are using biometric as a means of person authentication as it offer a convenient and easy way of authentication. Palm vein biometry is mostly used in many authentication system as it offer better security as veins are located on the subcutaneous layer of the skin and is impossible to be forged. However, there are still some issues in order to obtain high accuracy in palm vein authentication system such as some feature are not correctly extracted because of poor preprocessing process. Poor preprocessing process will produce weak keys for authentication purpose. Therefore, this paper proposed a hybrid of Gabor filter and maximum inscribe circle to obtain better region of interest for feature extraction as well as improving the accuracy of the authentication system

Processing of Watermelon Rind Dehydrated Candy

Watermelon rind (Citrullus lanatus) dehydrated candy was prepared by using osmotic dehydration process that involves slow impregnation of syrup before drying at 50°C for 8, 14 and 20 hours. From the study, it can be seen that drying time significantly affected the moisture content of the watermelon rind dehydrated candy. The moisture content was significantly decreased with drying time. For colour evaluation, the L* value of watermelon rind dehydrated candy was slightly decreased with drying time while the a* value was slightly increased. Watermelon rind dehydrated candy that dried for 14 hours was the most preferred sample by the panelists as it received the highest score for texture, taste and overall acceptability attributes. So, it can be concluded that 14 hours of drying time is the most appropriate time to dry the candied watermelon rind

MARS spectral molecular imaging of lamb tissue: data collection and image analysis

Spectral molecular imaging is a new imaging technique able to discriminate and quantify different components of tissue simultaneously at high spatial and high energy resolution. Our MARS scanner is an x-ray based small animal CT system designed to be used in the diagnostic energy range (20 to 140 keV). In this paper, we demonstrate the use of the MARS scanner, equipped with the Medipix3RX spectroscopic photon-processing detector, to discriminate fat, calcium, and water in tissue. We present data collected from a sample of lamb meat including bone as an illustrative example of human tissue imaging. The data is analyzed using our 3D Algebraic Reconstruction Algorithm (MARS-ART) and by material decomposition based on a constrained linear least squares algorithm. The results presented here clearly show the quantification of lipid-like, water-like and bone-like components of tissue. However, it is also clear to us that better algorithms could extract more information of clinical interest from our data. Because we are one of the first to present data from multi-energy photon-processing small animal CT systems, we make the raw, partial and fully processed data available with the intention that others can analyze it using their familiar routines. The raw, partially processed and fully processed data of lamb tissue along with the phantom calibration data can be found at [http://hdl.handle.net/10092/8531].Comment: 11 pages, 6 fig

Energy production from natural gas: evaluation of potential environmental impacts using life cycle assessment approach

Nowadays, sustainability is one of the main driving forces for worldwide economic growth especially in energy production. Conbustion of fuel such as natural gas for energy production not only produce electricity but also impacts to environment. In order to assess the environmental impacts of the natural gas power plant, study of life cycle assessment (LCA) has been carried out based on the data obtained from natural gas (NG) power plant in Johor, Malaysia. Data validation has been done by comparing the result with other assessment using the data available in the database. This paper presents the results of the LCA. From this study, it was found that there are insignificant differences in terms of the potential environmental impacts between the LCA study conducted using the data from the NG power with the assessment conducted using data from the database

Journal of Building Performance SUSTAINABLE CONSTRUCTION THROUGH LIFE CYCLE COSTING

Abstract Sustainable construction refers to the integration of environmental, social and economic considerations into construction business strategies and practices. It is the application of the principles of sustainable development to the comprehensive construction cycle from the extraction of raw materials, through the planning, design and construction of buildings and infrastructure, until their final demolition and management of the resultant waste. The implementation of Life Cycle Costing (LCC) in the sustainable construction industry is significantly important to construct the structures and infrastructure projects that will meet all the principles of sustainability. During the process of developing a project, LCC principles and techniques aim to provide best value from a whole life perspective. This paper, in reviewing the application of life cycle costing and sustainable construction, explores the correlation between these two elements and assesses how these can be used to achieve sustainability over the whole life of building projects

Sustainability of Ijtihad and Fatwa to Respond the Issue of Indirect Contributions in Matrimonial Property Claim: A Critical Assessment Fiqh of Property

The issue of sustainability of ijtihad and fatwas to elaborate on polemics of indirect contributions in matrimonial property claims has become an important issue today. The selection of the right ijtihad and fatwa will ensure that critical discussions in this matter can be photographed to a knowledgeable society. Many findings of jurisprudence writing stated the main methods in ijtihad and fatwas used by fuqahak of the past and contemporary to draw interesting discussions on this issue, but in the context of indirect contributions in matrimonial property claims, there is still much to be clarified. The main objective of this study is to find out the method of ijtihad and fatwa in the book of fiqh applied by the jurists in this issue. This study is qualitative in which a total of 20 books of turath have been researched and understood descriptively. The main collection methods used were in-depth reading and analysis and narrative evaluation was used to analyze the findings obtained. The results of the analysis prove that the indirect contribution related to housework and outdoor work, can be done Akad al-Ijarah for the wife is eligible to take a certain wage according to the jumhur view

Carbon footprint assessment at rest and service area of Malaysia highway

Malaysia has committed to reduce its greenhouse gas (GHG) emissions by up to 45 % by the 2030. With increasing urbanisation and living standards of people in Malaysia, there is certainty that there will be a substantial increase in human activities hence mobility via networks of the highway. Rest and Service Area (RSA) is one important facility of the highway network that operates 24 hours and utilises significant amount of energy for its lighting, cooling, and the restaurants activities. A substantial amount of carbon is emitted from the RSA due to electricity usage, water consumption, solid waste and wastewater, as well as fuel consumption from staff commuting and transportation of goods. The objective of this study is to identify the sources and estimate the operational carbon footprint at RSA Highway Malaysia. The collected data questionnaire was analysed using Microsoft Excel. As expected, the amount of CO2 emissions from electric consumption for each selected RSA about 90 to 94 % of carbon release compare to other sources. As a conclusion, the investments including a more efficient HVAC system and more efficient lighting, could make the building more energy efficient and may induce greater use
