TCP/IP Based Intelligent Load Management System in Micro-Grids Network Using MATLAB/Simulink  [PDF]
Muhammad Ali, Muhammad Zakariya, Muhammad Asif, Amjad Ullah
Energy and Power Engineering (EPE) , 2012, DOI: 10.4236/epe.2012.44038
Abstract: Computerized power management system with fast and optimal communication network overcomes all major dicrepencies of undue or inadequate load relief that were present in old conventional systems. This paper presents the basic perception and methodology of modern and true intelligent load management scheme in micro grids topology by employing TCP/IP protocol for fast and intelligent switching. The network understudy performs load management and power distribution intelligently in a unified network. Generated power is efficiently distributed among local loads through fast communication system of server in the form of source and clients in the form of loads through TCP/IP. The efficient use of information between server and clients enables to astutely control the load management in a power system of micro grids system. The processing time of above stated system comes out to be 10ms faster than others which ensure very less delay as compared to conventional methods. The Micro Grids system operating through TCP/IP control has been implemented in MATLAB/Simulink and results have been verified.
Construction of a Test Room for Evaluating Thermal Performance of Building Wall Systems under Real Conditions
International Journal of Innovative Research in Science, Engineering and Technology , 2013,
Abstract: Heat transfer across building wall systems (BWS) is now a globally important research topic that bears wide consequences on energy consumption as well as conservation in buildings. The numerous analytical and numerical works carried out in this area, especially in the GCC countries, requires actual experimental results in order to validate these studies. This paper is a description of the planning and implementation process used to construct one such experimental set up with high relevance to the present day scenario. All the types of wall systems used for residential and commercial buildings of recent origin are included and described. The methods adopted to maintain identical conditions are also detailed in this paper. Data regarding the thermal performance of the different wall systems under dynamic conditions for different climates will help to confirm the theoretical studies as well as to overcome the limitations of measuring instruments used.
Securing E-mail Communication Using Hybrid Cryptosystem on Android-based Mobile Devices
Teddy Mantoro,Andri Zakariya
TELKOMNIKA : Indonesian Journal of Electrical Engineering , 2012, DOI: 10.11591/telkomnika.v10i4.874
Abstract: One of the most popular internet services is electronic mail (e-mail). By using mobile devices with internet connection, e-mail can be widely used by anyone to exchange information anywhere and anytime whether public or confidential. Unfortunately, there are some security issues with email communication; e-mail is sent in over open networks and e-mail is stored on potentially insecure mail servers. Moreover, e-mail has no integrity protection so the body can be undectected altered in transit or on the e-mail server. E-mail also has no data origin authentication, so people cannot be sure that the emails they receive are from the e-mail address owner. In order to solve this problem, this study proposes a secure method of e-mail communication on Android-based mobile devices using a hybrid cryptosystem which combines symmetric encryption, asymmetric encryption and hash function. The experimental results show that the proposed method succeeded in meeting those aspects of information security including confidentiality, data integrity, authentication, and non-repudiation.
Iatrogenic insertion of impression mould into middle ear and mastoid and its retrieval after 9 years: a case report
Mohammad Awan, Moghira Iqbal, Zakariya Sardar
Journal of Medical Case Reports , 2007, DOI: 10.1186/1752-1947-1-3
Abstract: We report the case of a child, where the process of making the mould for a hearing aid led to the perforation of the tympanic membrane and pouring of mould material into the middle ear, necessitating surgical intervention. During initial surgery it was thought that all mould had been removed from the middle ear but 9 years later this child underwent cochlear implantation at the same center and remaining part of ear mould was discovered from mastoid cavity.The magnitude of hearing loss in Pakistan is enormous. One in twelve children of Pakistan suffers from some form of hearing impairment [1]. Many of them are unable to afford surgical procedures and resort to the use of cheap hearing aids fitted by untrained individuals or people lacking the required expertise. This predisposes the patients to significant complications during a process that is otherwise considered safe.We report the case of a child, where the process of making the mould for a hearing aid led to the perforation of the tympanic membrane and pouring of mould material into the middle ear, necessitating surgical intervention. During initial surgery it was thought that all mould had been removed from the middle ear but 9 years later this child underwent cochlear implantation at the same center and remaining part of ear mould was discovered from mastoid cavity.A 2 year old boy was brought to us by his parents for delayed speech development. There was no history of consanguineous marriage of parents. Pregnancy as described by mother was uneventful and there were no complications during delivery of this child. The birth weight of child was normal and there was no history of early infections like measles or meningitis. Clinical examination revealed intact tympanic membranes on both sides. Brainstem evoked response audiometry (BERA) showed bilateral severe peripheral hearing loss. As facilities of behavioral audiometery were not available at that time in our center and BERA was only done at two specific freque
The Physical Properties of N. lappaceum Seed as a Function of Moisture Content
Nor Syafarah Zakariya,Tajul A. Yang
Advance Journal of Food Science and Technology , 2012,
Abstract: This study studies the effect of 4 level of moisture content; 12.2333, 11.7133, 10.8167 and 10.3133% on physical properties (geometrical, gravimetrical and frictional properties). The results show that width, height and length were in negative linear relationship with moisture content as shown by the regression equation. Whereas sphericity, true density and static coefficient for all surfaces investigated exhibited negative quadratic model relationship, except for sphericity which positively correlate with moisture content. Cubic relationship were signified by arithmetic mean diameter, geometric mean diameter, surface area, mass, bulk density, porosity, filling and emptying angle of repose. Thus, by investigating the effect of moisture content on these physical properties, one can determine the most suitable condition for processing, transporting and storing of N. lappaceum seed.

Ebtissam M. Al-Madi, Manar AlJamie, Shaikha Al-Dukhail, Zakariya Mohammed, Neamat Hassan Abubakr
Open Journal of Stomatology (OJST) , 2016, DOI: 10.4236/ojst.2016.61004
Abstract: The aim of the present study was to assess the dietary habits and oral hygiene practice of dental students in a new dental school. A self-administered structured closed-ended questionnaire on demographic characteristics, medical history, oral hygiene and dietary habits was distributed to dental students. Results showed that One third of students indicated that they don’t consume low pH beverages (soft drinks) at all, while 48.9% drink a soft drink or two a day. Students took varying amount of time to consume their drinks. The majority of participants consumed citric juices, fruits and/or pickles at least once a day. 91.3% of students use either soft (41.8%) or medium (49.5%) toothbrush. Only a fifth (16.9%) of the students brush their teeth after drinking soft drinks and 58.2% brush their teeth after vomiting. In conclusion, young adults need to be aware about their dietary habits & oral hygiene, and also a proper dental health program needs to be applied.
Improved the Prediction of Multiple Linear Regression Model Performance Using the Hybrid Approach: A Case Study of Chlorophyll-a at the Offshore Kuala Terengganu, Terengganu  [PDF]
Muhamad Safiih Lola, Mohd Noor Afiq Ramlee, G. Sugan Gunalan, Nurul Hila Zainuddin, Razak Zakariya, MdSuffian Idris, Idham Khalil
Open Journal of Statistics (OJS) , 2016, DOI: 10.4236/ojs.2016.65065
Abstract: Efficiency and precision in prediction of Chlorophyll-a using this model is still a pandemic among researchers, due to the natural conditions in ocean water systems itself, which involved chemical, biological and physical processes and interaction among them may affect the model performance drastically. Thus, to overcome this problem as well as to improve the strength of MLR, we proposed a hybrid approach, i.e., an Artificial Neural Network to the MLR coins as Artificial Neural Network-Multiple Linear Regression (ANN-MLR). To investigate the performance of the proposed model, we compared Multiple Linear Regression (MLR), Artificial Neural Network (ANN) and proposed hybrid Artificial Neural Network and Multiple Linear Regression (ANN-MLR) in the prediction of chlorophyll-a (chl-a) concentration by statistical measurement which are MSE and MAE. Achieving our objectives of study, we used 4 parameters, i.e. temperature (°C), pH, salinity (ppt), DO (ppm) at the Offshore Kuala Terengganu, Terengganu, Malaysia. The results showed that our proposed model can improve the performance of the model as compared to ANN and MLR due to small errors generated, error reduced, and increased the correlation coefficient for all parameters in both MSE and MAE, respectively. Thus, this result indicated that our proposed model is efficient, precise and almost perfect correlation as compared to ANN and MLR.

A.A. Mohammed,A.S. Zakariya`u
Research Journal of Animal Sciences , 2012, DOI: 10.3923/rjnasci.2012.38.41
Abstract: The research was carried out to determine the growth performance of 84 day old Hubbard broiler chicks on various levels of supplemental Vernonia Amygdalina (VA). Four treatments were used including the control which had 0 g VA, treatments two, three and four had 300, 600 and 900 g VA, respectively as an additive in both the starter and finisher diets. The results of the growth performance showed that there were no differences (p>0.05) among all the growth performance parameters analyzed. Broilers on V300 and V900 showed increased feed intake and feed conversion ratio, respectively. There was decreased mortality in broilers fed V600 diet.
Plasma Internal Energy for Toroidal Elliptic Plasmas with Triangularity  [PDF]
Muhammad Asif
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.21002
Abstract: The Plasma internal energy is not conserved on a magnetic surface if nonlinear flows are considered. The analysis here presented leads to a complicated equation for the plasma internal energy considering nonlinear flows in the collisional regime, including viscosity and in the low-vorticity approximation. Tokamak equilibrium has been analyzed with the magnetohydrodynamics nonlinear momentum equation in the low vorticity case. A generalized Grad–Shafranov-type equation has been also derived for this case.
Dressing after Dressing: Sadra’s Interpretation of Change  [PDF]
Muhammad Kamal
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.31009

This paper deals with the doctrine of transubstantial change advocated by Mulla Sadra in which substances as well as accidents are thought to be in constant and gradual change. Against Aristotle’s doctrine of accidental change, Mulla Sadra argues that no stable ground can bring about change and since substance is renewable it cannot carry identity of a changing existent. Here we investigate whether identity is possible or not. If it is possible then what becomes a ground for establishing identity of changing substances.
