MALAYSIAN M-GOVERNMENT PORTAL FOCUSING ON TRANSACTIONAL-BASED SERVICES
This report explores the prospect of mobile government (m-government), an extension of
the growing movement toward electronic government (e-government). This project will
be mainly focus on introducing and developing a new wireless application for a
government agency. Currently the available m-government application is based on the
SMS technology. The services provided are mainly just to check basic individual
information such as check status of voting or the traffic summon. The objective of this
project is to provide a single point of contact for governmental related services and
community-based information which can be access by local citizen through mobile
phone. In the first part of the project, a survey has been conducted to gather the
requirements of the project and in the same time to analyze the level of understanding
and awareness about m-government services among local citizens. At the end of this
project, all the functions of the system should be completed and a user-friendly site can
be access through GPRS. As the conclusion, m-government is reflected in the changing
pattern of public interaction with government, where increasing amounts of interactions
will be through portable ICTs. It can help make public information and government
services available "anytime, anywhere"
Challenges of Multi-Factor Authentication for Securing Advanced IoT (A-IoT) Applications
The unprecedented proliferation of smart devices together with novel
communication, computing, and control technologies have paved the way for the
Advanced Internet of Things~(A-IoT). This development involves new categories
of capable devices, such as high-end wearables, smart vehicles, and consumer
drones aiming to enable efficient and collaborative utilization within the
Smart City paradigm. While massive deployments of these objects may enrich
people's lives, unauthorized access to the said equipment is potentially
dangerous. Hence, highly-secure human authentication mechanisms have to be
designed. At the same time, human beings desire comfortable interaction with
their owned devices on a daily basis, thus demanding the authentication
procedures to be seamless and user-friendly, mindful of the contemporary urban
dynamics. In response to these unique challenges, this work advocates for the
adoption of multi-factor authentication for A-IoT, such that multiple
heterogeneous methods - both well-established and emerging - are combined
intelligently to grant or deny access reliably. We thus discuss the pros and
cons of various solutions as well as introduce tools to combine the
authentication factors, with an emphasis on challenging Smart City
environments. We finally outline the open questions to shape future research
efforts in this emerging field.Comment: 7 pages, 4 figures, 2 tables. The work has been accepted for

Recording of time-varying back-pain data: A wireless solution
Chronic back pain is a debilitating experience for a considerable proportion of the adult population, with a significant impact on countries’ economies and health systems. While there has been increasing anecdotal evidence to support the fact that for certain categories of patients (such as wheelchair users), the back
pain experienced is dynamically varying with time, there is a relative scarcity of data to support and document this observation, with consequential impact upon such patients’ treatment and care. Part of the reason behind this state of affairs is the relative difficulty in gathering pain measurements at precisely defined moments in time. In this paper,we describe a wireless-enabled solution that collects both questionnaire and diagrammatic, visual-based data, via a pain drawing, which overcomes such limitations, enabling seamless data collection and its upload to a hospital server using existing wireless fidelity technology. Results show that it is generally perceived to be an easy-to-use and convenient solution to the challenges of anywhere/anytime data collection
A study on stryhcnos potatorum and pisum sativum as natural coagulants for meat food processing wastewater
Wastewater generated from meat food processing industry has significant effects on the environment. Many methods have been reported for removing turbidity, total suspended solids (TSS), chemical oxygen demand (COD), oil and grease (O&G) and colour from meat food processing wastewater (MFPW). The most common method among them is flocculation-coagulation process which is widely used. Although inorganic coagulants are prominent in wastewater treatments, its application may cause toxic residual. In this study, the attempt has been made to study the performance of S. Potatorum (nirmali) and P. Sativum (pea) seed as natural coagulants in the flocculation process. A further aim is to determine the optimum conditions for the treatment of MFPW effluents such as coagulant dosage, mixing rate and pH. An adsorption study was also carried out to study the adsorption potential of these coagulants to treat MFPW. A lab-scale treatment tank was developed to evaluate the effectiveness in MFPW treatment. Jar test results showed that optimum dosage, pH and mixing rate for S. Potatorum were pH 8 with dosage of 150 mg/L and 150 rpm mixing rate with the removal of turbidity, TSS, COD, O&G and colour are 91%, 97.6%, 58.4%, 79.9% and 84.3% respectively. Meanwhile, for P. Sativum, the optimum condition were observed at pH 8 with dosage of 150 mg/L and 150 rpm mixing rate with the removal of turbidity, TSS, COD, O&G and colour 87.8%, 97.3%, 65.5%, 77.9% and 76.5% respectively. The adsorption study was found that the analysis fitted well to the Langmuir isotherm for both natural coagulants. Results show that the percentage of turbidity, TSS, COD, O&G removal by chemical coagulants are quite similar than natural coagulants when lab-scale treatment tank was used to treat the MFPW. This indicated that these natural coagulants have a potential to use as alternative in wastewater treatment
