This paper presents an experimental investigation of the behavior of a biomass test material, wheat. Ground wheat grain is replicated as fine biomass base. The experiment is based on voltage application inside a capacitive sensor. This sensor allows the sensing of very small capacitive variation. The sensor is incorporated with an interface sensing circuit based on circular and semi-circular shaped electrode and modified capacitive bridge. Analysis of a particular material's flow sensing behavior has been carried out by evaluating the measurement data and assessing conformity between experimentally obtained and simulated data.

Technology trends in Malaysia are increasing as more and more users surf internet to search for information and to get connected with their friends and family members. Statistics show that the growth of internet usage among Malaysians has increased drastically during the last decade. This indicates people's acceptance towards technological developments and their interest towards spending more time online. One of the key sources of obtaining daily information is via newspapers. However, nowadays, publishing companies are facing a real challenge to generate revenues like past due to the availability of free online news. Strong competition in the market requires them to cut down operational costs, decrease price or even offer free newspapers for the readers and mainly rely on an advertisement for their income. In today's internet world, users' interest towards accessing the news around the world has changed to get instant updates rather than waiting for the printed edition to appear the next day. This has paved ways to the popularity of digital editions of newspapers. Usability is one of the key quality attributes that needs to be addressed and emphasized in these digital editions for a better user experience. For this research, five popular online news providers in Malaysia are considered and investigated, particularly for their weaknesses in usability. Based on the comparative study conducted, it was found that all of these digital news providers have deficits in accessibility, especially for disabled and elderly users. Negligible or very limited consideration for such an audience is taken into account in their design. This research aims to propose a modified system design for online newspapers in Malaysia satisfying international usability standards and aiming to provide more convenience for all groups of users while reading online.

Public services to citizen should be improved and developed to achieve better government and satisfying citizen as its main beneficiary. The quality of public services is mainly depended on government employee or civil servant as actor who is conducted all process of services and is supported by many factors. One of significant factors which influences to employee to give better public services is ensuring welfare of civil servant. To formulate policy or regulation to support welfare of civil servant, stakeholders needed the classification of welfare status of civil servant. This research attempted to define welfare criteria and classify civil servant data based on welfare measurement by utilizing Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and k-Nearest Neighbours algorithm (k-NN). This research used qualitative approach and quantitative approach in three governmental organizations, i.e. National Civil Service Agency (BKN; Badan Kepegawaian Negara), Ministry for Administrative and Bureaucracy Reform (KemenPAN&RB; Kementrian Pendayagunaan Aparatur Negara dan Reformasi Birokrasi) and National Institute for Administration (LAN; Lembaga Administrasi Negara). As the result, fifteen welfare criteria of civil servant is identified, i.e. current functional position, marital status, current structural position, health allowance, functional allowance, location of office, credit score, job performance, position allowance, appreciation, structural allowance, current age, number of children, year of work, and month of work. This is also successfully classified welfare status of civil servant by using k-NN with 80.87% accuracy prediction.
完善和发展对公民的公共服务，以实现更好的政府和满意的公民为主要受益者。公共服务的质量主要取决于政府雇员或公务员作为行为者，他们参与服务的所有过程，并受到许多因素的支持。公务员福利保障是影响公务员能否更好地提供公共服务的重要因素之一。为了制定支持公务员福利的政策或法规，利益相关者需要对公务员福利状况进行分类。本研究尝试利用TOPSIS (Order Preference Technique by Similarity to Ideal Solution)和k-Nearest neighbors (k-NN)算法来定义福利标准，并在福利度量的基础上对公务员数据进行分类。本研究以三个政府组织为研究对象，分别是:国家公务员局;行政和官僚主义改革部(KemenPAN&RB;Kementrian Pendayagunaan Aparatur Negara dan Reformasi Birokrasi)和国家行政研究所;国家行政管理局)。从而确定了公务员的15项福利标准，即现任职能职位、婚姻状况、现任结构性职位、健康津贴、职能津贴、办公地点、信用评分、工作业绩、职位津贴、增值、结构性津贴、现任年龄、子女人数、工作年限、工作月份。利用k-NN对公务员福利状态进行分类，预测准确率达到80.87%。

The smart home concept has constantly gained popularity over the past decades following the advent of technology. However, concerns on flexibility and infrastructure requirements discourage the widespread implementation of this concept. This project aims to improve the overall experience of a smart home by integrating the Wi-Fi IEEE 802.11 wireless communication standard into a standard smart home sensory network. The tasks of the project were centred on the development of a Wi-Fi integrated smart home system with a PIC® microcontroller and a Wi-Fi module as the core components. Additional components such as light-dependent resistor (LDR), temperature sensor, light-emitting diodes (LEDs) and DC motor were included to mimic a real life home environment. A custom designed Android graphical user interface (GUI) application was also developed to enable automated and manual control of the modelled smart home. The final smart home prototype presented the integration of Wi-Fi into a smart home network that grants users with greater flexibility while preserving the existing smart home experience.

the design of rectenna for wireless energy harvesting is presented in this paper. The rectenna design consists of a microstrip patch antenna and a rectifier circuit, in which both of them resonate at 2.45 GHz. CST software was used as the simulation tool of the proposed microstrip patch antenna. Then, the designed antenna was fabricated and assembled together, and tested using network Analyzer. The rectifier consists of two tapered microstrip lines, a Schottky diode, a λ/4 microstrip line, a matching microstrip line, and an output low pass filter. The circuit is printed on the substrate of FR4 (εr = 4.3 and h = 1.6 mm). The circuit was designed and optimized using Advance Design System (ADS), then fabricated using micro-strip lines with an FR4 substrate. According to the received wireless power, the values of output DC voltage and power have been measured and the best value of load resistance to harvest maximum output DC power has been selected through simulation.

The quality and reliability of electric power supply are the key indicators for the comfort of a society. Hence, to serve customers with high quality electricity, the Supervisory Control and Data Acquisition (SCADA) system is being used in the distribution system (DS) for power monitoring and control. The SCADA is feed with operation data like current and voltage via Feeder_Remote Terminal_Units (FRTUs). The FRTUs are capable of triggering actions to detach the portion of DS experiencing an unusual condition. Nevertheless, the existing grids do not operate at their optimal capacity due to the usage of one way data communication installations. Thus, to optimize the operation of the legacy power distribution grids, the innovation of the state-of-the-art communication techniques play a vital role-leading to the creation of smart grid Systems. This paper reviews the development of wireless communication technologies envisioned as full-duplex information exchange medium in the on-going development of Smart Grid Systems.

Various arithmetic circuits such as multipliers require full adder (FA) as the main block for the circuit to operate. Speed and energy consumption become very vital in design consideration for a low power adder. In this paper, a 4-bit FA using complementary metal oxide semiconductor (CMOS) technology had been designed successfully. A 1-bit hybrid FA (HFA) using 13 transistors (13T) with a new SUM circuit is the basis for the building block of the 4-bits FA. Four HFAs are cascaded together and each HFA is constructed from three modules. Exclusive-OR (XOR) gate of three transistors is the first module. The second one is the new SUM circuit designed using only four transistors to generate the HFA sum. The third module is a special carry circuit with input coming from the first module and several other inputs to generate the HFA carry output. The full adder design is simulated using Tanner EDA version 16 using General Process Design Kit (GPDK) of 250 nm CMOS technology. Performance parameters such as power consumption and delay were compared to some of the existing designs. With a 1.8V voltage supply, the average power consumption of the proposed HFA was found extremely very low which is 2.09 μW and a moderately low delay of 350 ps. As for the 4-bit FA, the average power consumption is 65.37 μW with a delay of 1300 ps.

A novel and facile method at lowest concentration of titanium (IV) butoxide with hydrochloric acid at 150 °C temperature for 3 hours was implemented for the growth of Titanium dioxide (TiO2) nanorod arrays (TNAs) on fluorine-doped tin oxide (FTO) glass substrate. The deposited TNAs were characterized by field-emission scanning electron microscopy (FESEM), and ultraviolet-visible (UV-Vis) spectrophotometer. Self-powered UV photosensor was designed based on photo-electrochemical cells (PEC) using the deposited TNAs as photo anodes. The performance of the fabricated UV photosensor was studied based on its photo-generated current and response under UV irradiation (365 nm). The fabricated UV photosensor displays fast response and recovery time under an ON/OFF state of UV irradiation with comparatively high sensitivity. The photosensor fabricated at the lowest 0.05 M of titanium (IV) butoxide with hydrochloric acid of TNAs exhibits photo-sensing property as photo-anodes, and can be implemented for the application of UV photosensor. Large surface area of TNAs leads to the high generation of photocurrent and shows increment in conductivity under UV irradiation.

Along with the development of globalization, there is a change of values and way of life in local communities. That change had an impact on the loss of potential resources of traditional knowledge. Because of the important of traditional knowledge, many people from government, non-profit organization (NGO) and others attempted to document it into digital form. However, that activity is not fully supported by communication and technology (ICT) infrastructures, e.g. mobile technology, so that process of documentation was not coordinated and integrated well. This research attempted to develop mobile application based on situation in documenting traditional knowledge in Indonesia. The mobile application development was used CommonKADS as methodology with some modifications. As the result, mobile application is successfully designed and represented into six component models, i.e. situation model, agent model, task model, knowledge model, communication model and design model. Then, all models are used as basic to deploy mobile application to meet user requirement and solve problem that has been identified and defined at beginning of research phases.
