Bangla Braille Information System: An Affordable System for the Sightless Population
Mohammad Abu Yousuf,S.M. Saif Shams
Asian Journal of Information Technology , 2012,
Abstract: All over the world, persons with visual handicaps have used Braille as the primary means to reading information. Also, the concept of Braille has been accepted as a universal approach that works across the boundaries of the world. Different countries of the world have adapted the system of Braille to suit their languages. This study presents modern bangle Braille system that can be used by blind people to read and write. A Braille code is a code similar to a code page, that maps the characters of a writing system to the 6, raised dots (or bits) of a Braille cell. This study illustrates the idea to translate the texts in Bangal to the corresponding Braille documents.
Concept of Mobility Based Video-Telephony in Mobile Ad Hoc Network (Manet)
Mohammad Abu Yousuf,Nurunnahar Begum,Badrunnesa Sultana,Nurul Amin
Asian Journal of Information Technology , 2012,
Abstract: A Mobile Ad Hoc Network (MANET) is a collection of wireless mobile computers forming a temporary network, without any fixed base station. The network nodes communicate with one another over scarce wireless channels in a multi-hop fashion. The Ad Hoc network is adaptable to the highly dynamic topology resulted from the mobility of network nodes and the changing propagation conditions. In various applications, where a fixed backbone is not available, a readily deployable wireless network is needed. Mobile Ad Hoc networks are also a good alternative in rural areas or third world countries where basic communication infrastructure is not well established. This study describes the idea of Ad Hoc networking and scenarios where this technology will make an impact. How the environment of an Ad Hoc network is very different from the wired environment, and the effect this has on the design and operation of routing protocols for mobility based Video-Telephony in Ad Hoc networks is widely explained in this study.
A New Encryption Method for Short Message Service (SMS)
Mohammad Abu Yousuf,Mustafa Hasan,S.M. Saif Shams
Asian Journal of Information Technology , 2012,
Abstract: This study shows an encryption method for Short Message Service (SMS) to reduce amount of required memory space of data for device or to increase the number of bytes to transmit. SMS is a very popular service. SMS are developing very rapidly throughout the world. As SMS is an offline message service it`s a huge pressure for server memory. In traditional SMS system it is possible to send maximum 160 characters and each character occupies one byte of memory space. In this study an encryption method is present by which each character occupies less than a byte and will save huge mobile set memory space and at the same time present encryption method will save server memory space.
Electrochemical Behavior of Malachite Green in Aqueous Solutions of Ionic Surfactants
Mohammad Mijanur Rahman,M. Yousuf A. Mollah,M. Muhibur Rahman,Md. Abu Bin Hasan Susan
ISRN Electrochemistry , 2013, DOI: 10.1155/2013/839498
Abstract: Electrochemical behavior of malachite green (MG) oxalate in aqueous solution was studied in the presence of a cationic surfactant, cetyltrimethylammonium bromide (CTAB), and an anionic surfactant, sodium dodecyl sulfate (SDS) at a glassy carbon electrode using cyclic voltammetry. The electrochemical oxidation of MG has been characterized as an electrochemically irreversible diffusion-controlled process. Oxidative peak current sharply decreased with increasing SDS concentration, while a slight increase with increasing [CTAB] was apparent. The apparent diffusion coefficient, the surface reaction rate constant, and the electron transfer coefficient of MG clearly show correlation of the electrochemical behavior with the dissolved states of the surfactants. Electrochemical observations together with spectrophotometric results at varying surfactant concentrations provide evidence of interaction of MG with the surfactants to varying extent depending on the type of the surfactant and the concentration. 1. Introduction Triphenylmethane (TPM) dyes, an important class of synthetic organic compounds, have been a promising material for diverse applications, which inter alia include the following: as fungicides in aquaculture, as parasiticides in pharmaceuticals, as dye materials in industry, and as redox mediators, bioprobes, and pH indicators in both fundamental and applied sciences [1–6]. A proper understanding and development of fundamental knowledge base of physicochemical properties of TPM dyes have therefore attracted significant attention. Techniques so far employed for this are polarography [7], conductometry [8, 9], potentiometry [10], spectrophotometry [11, 12], electrochemical methods [13], membrane selective electrode [14], and so on. Dyes of TPM backbones such as malachite green (MG), crystal violet [15], ethyl violet [16], and victoria blue B [17] are electrochemically active, and recent surge of interest has been the exploration of the redox behavior of such dyes. Among the TPM dyes the prospect of MG (chemical structure shown in Scheme 1) for versatile applications [1] prompted many researchers to study the electrochemical behavior of MG for development of electrochemically switchable devices. The electrochemical oxidation of MG occurs at -containing lone-pair electron, and the reduction process is due to reduction of oxidized tertiary amino group of MG [2, 10]. In acidic aqueous solutions, the anodic oxidation of MG leads to the formation of the oxidized form of -tetramethylbenzidine (TMB) ([ -biphenyl]- -diamine), that is, TMBOx whereas the
A Secure Image Steganography Using Advanced Encryption Standard and Discrete Cosine Transform  [PDF]
Ashraful Tauhid, Maisha Tasnim, Saima Arifin Noor, Nuruzzaman Faruqui, Mohammad Abu Yousuf
Journal of Information Security (JIS) , 2019, DOI: 10.4236/jis.2019.103007
Abstract: Cryptography and Steganography are two prominent techniques to obtain secure communication over the shared media like the Internet. Steganography is slightly ahead of cryptography because of its stealthy characteristics. In this paper, a new method has been proposed which combines cryptography and steganography to ensure even more secure communication. The Advanced Encryption Standard (AES) in spatial domain of the carrier/cover image and Least Significant Bit (LSB) replacement in the transformed domain of the same image has been used after performing a Discrete Cosine Transform (DCT) on the pixels. An additional layer of security has been introduced by applying XOR operation on the AES encrypted message with the pixel values of the carrier image. The Peak Signal to Noise Ratio (PSNR) of the proposed algorithm is better than most of the similar algorithms. With better PSNR, the proposed method depicts a three layer of security of the information and error free decryption.

Ghada Mohammad Abu Shosha
Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.54032
Abstract: Background: Breastfeeding is the desired nutritional method for infants. Some infants’ characteristics were found influential to mothers’ point of views toward breastfeeding. However, the relationship between infants’ characteristics and mothers’ attitudes toward breastfeeding is still uncertain. The aim of this study was to assess infants’ characteristics and their impact on Jordanian mothers’ attitudes toward breastfeeding. Methods: A descriptive cross-sectional design was used. A sample of 130 mothers was selected conveniently from mothers attending four major governmental maternal-child health centers at Zarqa city in Jordan. The Iowa Infant Feeding Attitude Scale along with infants’ characteristics data sheet were used for data collection. Results: A more positive attitude toward breastfeeding was manifest (mean 63.5, SD: 4.67). Positive attitudes toward breastfeeding were higher among women who delivered normally than women who delivered by cesarean section (p = 0.040). In addition, women who had healthy infants were more likely to have positive attitudes toward breastfeeding compared to women with ill infants (p = 0.021). However, women with preterm deliveries were less likely to have positive attitudes compared to women with full-term deliveries (p = 0.013). Likewise, women whose infants admitted to neonatal intensive care unit recorded less positive attitudes toward breastfeeding than women with healthy neonates (p = 0.043). Gestational age, admission to neonatal intensive care unit, infant’s health status, and type of delivery, were factors influencing mothers’ attitudes towards breastfeeding. Conclusions: Jordanian mothers have positive attitudes toward breastfeeding. However, positive attitudes are subject to different infants’ characteristics that should be considered while undertaking heath education programs for promoting breastfeeding. More focusing is recommended for women who delivered preterm infants, women who have ill infants, and women who delivered by cesarean section.

Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.614156
Abstract: This study aims to investigate the level of inclusion and balance of multiple intelligences in the Arabic Language textbooks in light of Gardner’s Theory using the analytical descriptive approach. Eight textbooks in grades (1 - 4) for the first and second semesters were taught in schools in the Jordanian educational system in 2013/2014. The selected textbooks were analyzed using Multiple Intelligences (MI) checklist devised by the researcher based on the framework of the Theory of Multiple Intelligences to examine them in relation to different intelligences as reflected through various activities, questions and tasks. The study sample consisted of all Arabic Language textbooks for the grades from 1 - 4. Results of the study showed that the verbal/linguistic intelligence in the textbooks in general scored the highest frequency amongst all types of intelligence; meanwhile the musical intelligence in the textbooks scored the lowest frequency among all types of intelligence. The study concluded with a recommendation to consider the necessity of employing all types of intelligence in designing Arabic language textbooks for young learners.
Keep on Striving: The Impact of Psychosocial Support on Jordanian Adolescents with Cancer  [PDF]
Ghada Mohammad Abu Shosha
Health (Health) , 2016, DOI: 10.4236/health.2016.810095
Abstract: Having cancer during adolescence stage causes stressors in patients’ lives. They are responsible for dealing with many new situations and stressors. Coping with such stressors can be influenced by psychosocial factors. This study aimed to explore the impact of psychosocial support on adolescents with cancer. A qualitative exploratory design was used to understand the experience of psychosocial support from the perspectives of the patients. Twenty adolescents with cancer were selected purposefully from two major cancer treatment centers in Jordan. Semi-structured face-to-face interviews were used to obtain the participants’ perspectives. Data were analyzed using thematic analysis approach. Findings revealed three major themes: “supportive structure”, “precious aspects of psychosocial support”, and “cancer could be defeated”. Participants expressed their satisfaction with the psychosocial support provided to them. However, they asked for further improvement in hospital facilities, playrooms and leisure activities. In conclusion, having a strong psychosocial support system will help adolescents to cope with cancer. Family, friends, and the surrounding environment are the key elements in installing hope and helping adolescents to go through cancer experience. Nurses are advised to adopt these psychosocial keys in order to create age-related activities that would improve the patients’ coping with cancer.

Open Journal of Blood Diseases (OJBD) , 2016, DOI: 10.4236/ojbd.2016.63005
Abstract: Adherence to thalassemia treatment including chelation drugs is influenced by numerous factors. This study aims to explore beliefs about iron chelation therapy and adherence to this medication in Jordanian children with thalassemia major. In this descriptive cross-sectional study, seventy three patients were selected conveniently to complete the study instruments. Participants reported high adherence to their chelation therapy (88.1%). The majority (87.6%) expressed necessity for chelation therapy. However, 42.18% of the participants expressed their concerns about the therapy in which 57.9% of them showed concerns about dependency on medicine and 46.4% of them revealed concerns about the long-term effect of medicine. Overall, about 12.9% of the participants recorded correct and complete answers about thalassemia and its treatment. Knowledge about thalassemia and concerns about chelation were not significantly associated with adherence to the chelation therapy (r = 0.32, p = 0.19; r = 0.29, p = 0.25, respectively). However, there was a significant positive relationship between beliefs about the necessity of the therapy and adherence to it (r = 0.38, p = 0.03). In conclusion, Jordanian children showed proper adherence to their chelation therapy. Health care professionals should discuss patients’ concerns about chelation therapy which might increase patients’ adherence to their therapy.
Solar Panels Cleaning Frequency for Maximum Financial Profit  [PDF]
Mohammad Abu-Naser
Open Journal of Energy Efficiency (OJEE) , 2017, DOI: 10.4236/ojee.2017.63006
Abstract: Allowing the dust to accumulate on solar panels without adequate cleaning leads to huge monetary losses. Proper judgment of when to call for washing of solar panels is a compromise between gross costs of cleaning the panels and how much reduction in efficiency of solar panels can be tolerated. In this paper, we derive a formula for the optimal number of days between cleaning cycles of a solar array by minimizing the cost of cleaning the array and the lost revenue from the unclean panels. The formula will aid in deciding cleaning periods based on the environment in which the solar panels are installed and cost incurred from undertaking the washing process.
