Stroke accounts for high rates of mortality and disability. It levies great economic burden on the affected subjects, their family and the society at large. Motor impairments after stroke mainly manifest themselves as hemiplegia or hemiparesis in the upper and lower limbs. Motor recovery is highly variable but can be enhanced through motor rehabilitation with sufficient movement repetition and intensity. Some previous studies regarding home-based rehabilitation process have shown improvement in promoting human movement recovery. However, the existing rehabilitation devices are expensive and need to be supervised by physical therapist, which are complicated to be use at home. Cost effective assistive devices that can augment therapy by increasing movement repetition both at home and in the clinic may facilitate recovery. This current work aims to develop a device that can enhance motor recovery by providing feedback to both the therapist and the patient on the number of hand movements (wrist and finger extensions) performed during therapy. Further work will reveal whether this feedback can enhance recovery of hand function in neurologically impaired patients. In conclusion, this project may pave a new way in the development of new arm rehabilitation monitoring devices which can benefit human lives.Â Â

Published: July 2024

Preparation of porous NiTi alloy by Metal Injection Moulding (MIM) requires several important steps, starting from mixing of elemental powders with polymeric binder until the final process of sintering. In this present work, some initial findings on the powder-binder mixture, so called feedstock were investigated.Â Theoretical density of Nickel, Titanium and NiTi powders which were determined using pycnometer are 8.97 g/cm3, 4.58 g/cm3 and 6.36 g/cm3 respectively. The composition for Nickel and Titanium powders mixture studied was 56wt% Ni - 44wt% Ti or nearly around 50.9at% Ni â€“ 49.1at% Ti and mixing torque analysis performed using a Brabender Mixer suggested two powder-binder volume fractions of 61%vol and 64%vol. The elemental powders of Nickel and Titanium with particle size of 20 Âµm and 22 Âµm were mixed along with water soluble binder system comprised of Polyethelene Glycol/Polymethyl-metacrylate/Stearic Acid (PEG/PMMA/SA) by a Dual-Asymmetric Centrifuge (DAC) speed mixer. The feedstock prepared was evaluated by flow analysis using Capillary Rheometer at four different temperatures; 120ÂºC, 130ÂºC, 140ÂºC and 150ÂºC and morphological analysis by scanning electron microscopy (SEM). Results showed that DAC technique used in the present work promoted significantly fast processing of MIM feedstock in comparison with conventional method. Besides, the feedstock prepared exhibited good flow behavior, particularly at the temperature of 140ÂºC, which is supported by SEM morphology that showed uniform powder-binder bonding.Â Â Â
Comparative study on viscosity and drag reducing performance between hydroxypropyl cellulose and hydroxypropyl cellulose-surfactant mixture
Authors: Moreton-Shabirin Ainoon , A Abdulbari Hayder 
Published: July 2024

Ammonium Chloride (BZK) was found to enhance the drag reduction performance of a semi-rigid polymer Hydroxypropyl cellulose (HPC) in turbulent pipe flow. Rheology test showed that HPCâ€™s viscosity was higher than that of HPC-BZK mixture, and this showed that the presence of BZK had weakened the intermolecular strength of HPC molecules. Pressure-drop measurements indicated that HPCâ€™s and HPC-BZK mixtureâ€™s drag reducing performance are (a) dependent on Reynolds number, and these mildly enhanced in the presence of BZK and (b) weakly dependent on additives concentration. Both HPC and HPC-BZK mixture showed a maximum drag reduction of 27% and 31%, respectively at Reynoldâ€™s no. 59448 and gradual degradation thereafter. Although the presence of BZK enhanced the drag reduction performance of HPC in the mixture form, the experimental data indicated that BZK did not extend HPCâ€™s drag reduction performance nor assist the HPC to re-assume itself following structural degradation.Â Â Â

Authors: K. El .Abbadi Nidhal , Saleem Eman 
Published: July 2024

Images colorization is the operation of append colors to the grayscale image by using a reference color image. The main problem ofÂ coloring a grayscale image involves constructing three dimensional image from one dimensional array. The current paper developed a fully automatic image colorization system based on the singular value decomposition (SVD) transformation. SVD used to measuring the best pixel in the reference image proper to colorize the gray image, depending on comparing the pixel value and their neighbor values of the gray image with pixel value and their neighbors in the reference image. Using the color space is more suitable to many digital image processing than the RGB, for that the author suggested to convert reference image to the CIELab color space in this proposal. GrayÂ Â image normalized according to the (L channel) of reference image. Ultimately, the intensity of the selected pixel in the gray imageÂ Â combine with (a, b channels) values of the best pixel from CIELab color space of reference image, which is finally converted to RGB color image. The suggested algorithm is the first algorithm utilized the SVD for image colorization which give good and promised results compared with other methods, and can be enhanced in the future.Â Â

Published: July 2024

Fixed spectrum allocation policy in the wireless networks leads to variations in the spectrum utilization of the allocated spectrum. This variation ranges from 15% to 85%, with high variance in time and geographical area in a random manner. However, the spectrum scarcity, the new technologies which provide high data rate but need more bandwidth, the new demand of lower cost per bit, and the in-efficiency in the spectrum bands all these problems can be addressed using the Cognitive Radio (CR) technology. In this paper, the CR aspects and functionalities are discussed, a brief discussion about the Medium Access Control (MAC) protocol design for a Cognitive Radio Network (CRN) is introduced, and the main critical CR issues as well (including heterogeneity induced problem, multichannel spectrum sensing, Common Control Channel (CCC) problem, spectrum mobility, and the self organization schemes in the CR functionalities).Â Â Â

Authors: Sankaran Sathya , Rajasekaran Rajkumar 
Published: July 2024

Personal Health Records may contain personal data along with medical data that is available in Electronic Health Records. This research proposes an encryption decryption method with encoder decoder for records in well established hospitals that store medical records in terms of terabytes. For encryption, the medical information including images is converted into binary. This is sent to an encoder and the information is stored in chunks to form a matrix. Then it undergoes matrix transformation and split into sub matrices. This is sent to the destination. The reverse is done in the decryption module. Cryptanalysis for the algorithm used and brute force attack is almost impossible or takes a number of years. A comparative study of the proposed algorithm is done with DES, AES, IDEA and BLOWFISH and it is realized the proposed algorithm is immune to cryptanalysis methods to which the compared algorithms are not. The personal health records are located in the cloud. The encryption decryption provides data security which is used to provide cloud security.Â Â
An investigation of application developerâ€™s awareness and attitude towards open government data in Malaysia
Authors: Wu Tong , Mohd Mahdzir Akbariah 
Published: July 2024

Governments across the globe are publishing official datasets and making it readily available online as open government data (OGD). Leaders of the OGD movement sought to engage developers to make information available not only for greater transparency and accountability but also incorporate it into applications, services and business developed to serve the public and foster social and economic growth. Given rising concerns over the OGD movement, Malaysia also navigates new frontiers of this digital revolution and embrace openness as part of the public effort across government sectors. However, much more efforts need to be done in order to help translate the data openness into practical results. In this regard, this paper briefly reviews the content of the Malaysia government data portal and conducted a preliminary survey gathered from various application developers aim to investigate the level of awareness and attitude based on their perceptions towards OGD in Malaysia. Presently, the results indicate that OGD in Malaysia is still scattered and the awareness among developers is still slim. Many developers are still reluctant and uncertain concerning the pursuit of OGD in their current projects. These findings argue that the potential of OGD is real, but it requires more positive promotion and improvement to enhance the level of awareness and civic consciousness so that successful application would take off in the future.Â Â

Comparison of semi- spherical solar collector with flat plate solar collector
Authors: Moravej Mojtaba , Namdarnia Fatemeh , Esmaili Leila 
Published: July 2024

The efficiency of each solar system depends on the amount of radiation that it receives. The evident characteristic of solar energy is its change throughout the day and during different seasons. Another feature of this energy is the change of position of the sun in the sky relative to Earth. The greatest amount of radiation from the sun comes when the sun's rays rise vertically to the desired level. For this reason, in solar collector systems, the collector must rotate to the sun, otherwise, the amount of accumulated energy falls. The purpose of this paper is to compare the performance of a solar semi- spherical collector with a flat plate collector. In this study, the semi- spherical solar collector does not need to be placed in a specific direction and also does not need the sunlight tracking mechanism to get the most amount of sunlight. Due to the semi- spherical shape of this collector, all geographic directions have the same effect. It also exhibits the highest resistance to wind blowing in terms of greater stability and lack of vibration and destruction. But the flat plate collector should be in the direction of radiation. In this research, experimental data from a flat plate collector in a closed cycle have been investigated with experimental data from a semi- spherical solar collector, simultaneously and it is shown that reducing the radiation or wind velocity will have the greatest impact on the flat plate collector and its outlet temperature. The experiments showed that the highest efficiency was in semi-spherical solar collector and it was about 67% and the highest outlet water temperature was in the flat collector and around 76Â°C.Â Â Â Â

Published: July 2024

The consumption pattern of Malaysian consumers has changed markedly since 2005 as shown by several indicators such as consumer price index, per capita income and inflation rate. Instability of economy, increased in food prices, political stability, employment, debt, work life balance, increased in utility bills and fuel prices, health and crimes become major concerns for Malaysian consumers especially in urban areas to be more cautious in their spending. This study attempts to examines the factors contributing to consumption model for Malaysian consumers in rural and urban areas. From the literature, eight antecedents of Malaysian consumption pattern were identified. Consumer lifestyle, consumer value, consumer motive, consumer preference, and marketing mix of price, product, place, and advertising were measured using 7-point Likert scales. From 1400 questionnaires distributed to households, 851 were returned representing 61 percent response rate. The findings indicate support for validity of measurement models of all variables utilized for both model rural and urban. Using Structural Equation Modeling (SEM) of SMARTPLS 2.0 technique, it was found that advertising is not a predictor for consumer motive for both model, rural and urban.Â Apart of that, the reason of price hikes has been discussed. On the other hand, rural model postulates better R2 than the other model. The finding implies that Malaysian government need to continuously campaign for consumers about the implementation of GST and its consequences for consumers. In addition, the instability of economic changed the consumption pattern throughout their lifestyle, value, motive and preferences.Â
Operation of Reheat Steam Temperature Control Concept in Sub Critical Boiler: Operational Review Practices and Methodology
Authors: S Samsudin. , Aziz Nuraini A. 
Published: July 2024

In subcritical boilers, spray water system and feed water flow are applied to control the superheated steam temperature. Meanwhile, for reheat steam temperature control, many methods are being adopted namely burner tilt, gas recirculation, and excess air and steam bypass as primary control and feed water is envisaged as an emergency control. In a large boiler operation, the boiler is operated in sliding pressure mode the cold reheat steam temperature is higher compared to constant pressure operation.Â To ensure the correct temperature control for reheat steam with high pressure, the right method and sufficient mechanism operating the boiler is required. In fact, spray is not used for reheat steam temperature control because the boilers are designed for constant pressure operation since the spray quantity required will be large for an impact on plant heat rate. The boilers used for this study were operated under sliding pressure mode; hence, reheat steam temperature control by spray is a common practice in subcritical boiler operations. This paper dealt with the advantages and disadvantages of using spray by looking at boiler performance for RH steam temperature control in lieu of other control mechanisms.
