Education is a guaranteed and innovative vehicle to a high standard of living, an avenue for intellectual interactions, social networking vehicle amongst current academic professionals, college and university graduates, the political, local, state, and community. The primary purpose of a life-long education is to promote personal and professional development and the advancement of national and world economy. History supports the premise that after continued self-regulating attempts, time has come for current and future graduates, professionals, and the entire education community to focus on the primacy of computer information technology. Esin (2013) in his studies on global education reform posited that computer information technology has widened human access to vital data, video and information transmission and communication. The evolution of computer information technology has created an irreversible phenomenon in instruction and learning endeavors, and continues to serve as the best medium for multiple sources of information and communication. Emergence of computer information technology has equally created a wide-range of opportunities for greater production; eradicate the lingering global language barriers, and creating a working podium in the academic and political world. It is a proven tenet that the continued use of computer information technology and associated devices such as the Internet, mobile telephones, and electronic mail for data, video, information transmission and communication has improved the standard of living and enhanced the exchange of ideas, effective method of instruction, a decrease in alarming attrition rate of students dropping out of the degree programs and improvement in academic performance.

The objective of this research was to reduce the rate of bending defects in hard disk drive suspensions by applying the Six Sigma method. The study first defines the problem, gives the project objective and scope. Then, the Attribute Agreement Analysis was performed to ensure the reliability of the inspection results. Process Mapping then lists the Process Input Variables that lead to bending defects. Then, the effects of various variables on bending defects were analyzed using the Cause and Effect Matrix. The criteria of the Failure Mode and Effects Analysis technique were then used to reduce the number of variables and prioritize the Key Process Input Variable (KPIV) for further analysis. Following this, process factors were improved by changing tray design in Laser Welding, Cutting, Forming, Final Trim, Damper Attachment and Backend processes. The tooling die was modified in the forming process. The handling tool was modified in the Final trim and Damper Attachment processes. Finally, the creation or revision of standard work instructions (Do/ Don't) were done and the operators were trained. After that, a control plan was set up to control production processes. The results show that the bend defect rate decreased from 15649 PPM to 9263 PPM.

In this study, ultrasonic treatment of apple mash was used for improvement in antioxidant content in the fruit juice. Firstly, the effects of ultrasonic power and time on the ascorbic acid and phenolic content as well as the antioxidant activity of the apple juice were investigated. Response surface methodology was then applied to optimization of sonication conditions for maximizing the antioxidant activity of the juice. The optimal ultrasonic power and time were 20 W/g and 7.3 min, respectively under which the antioxidant activity of the apple juice achieved maximum of 13.18μmol Trolox equivalent antioxidant capacity per g dry weight (TEAC/g DW) using 2,2'-azinobis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) essay. This value was 67.5% higher than that in the control sample without ultrasonic treatment.

Cloud Computing is a vast infrastructural and rising pool which provides huge storage of data in one sphere. Organizations nowadays are in the marathon of equipping the whole system in a cloud form. In this paper we are concern for providing a greater security to the cloud data from data mining attacks. Time complexity and security issue is taken into consideration. Data security and privacy protection issues are associated with cloud computing have been enhanced and modernised in this paper. We have proposed an architecture comprising of various components and network designs which provides a high level of security to the data. The rate of growth of cloud computing is so fast that it has already put its head in the mortar and is spread as the most durable untiring technology now. As cloud computing is a store house of data which might get affected by data mining attacks so we have launched this architecture.
Irrigation is the process of artificially supplying water to land where crops are cultivated. Considering the characteristic and methods of irrigation in Sudan, this paper brings forward new programmable device for remote control and monitoring of irrigation system. Three levels are included in the system: the microcontroller for information processing using atmega32 with a control program for real time measurement and control , GSM unit to provide wireless communication via cell phones for monitoring of field parameters and control requirement, with the aid of sensors (temperature, moisture and humidity sensors). RF transmitter is used to collect and transmit data from field to the controller which includes RF receiver. The System operates in three modes: the first one is for closed field (green houses) where the weather parameters must be set according to the plant requirement via system keypad for automatic control of irrigation process. The second mode is used in case of regular irrigation where the plant is to be irrigated in regular intervals ,while the third mode is for the case where the plant is to be irrigated in irregular intervals. The system has also the ability to operate as a weather station through the explanation mode provided with the system. In this mode the user can feed the system with the weather parameters(temperature ,humidity, dew point and rainfall) ,then the user will receive a real time feedback SMS explaining the condition.

The correlation of dry density and porosity of some rocks from the Karoo Supergroup in the Eastern Cape Province of South Africa was carried out in order to establish a relationship between the two parameters that will possibly serve as a guide on the engineering design, especially on the type of casing materials to be used when considering fracturing of the Karoo for shale gas. The densities of rock samples were determined using the buoyancy determined volume. The correlation was determined by plotting a chart of particle density against the porosity and fitting a least squares line through the data. The average densityvaluesrange from 2.5258 - 2.7723cm-3.The average porosity values range from 0.4931–3.3095 %.The correlation coefficient values R range from 0.9491 - 0.9982.The meanof the porosity values obtained from the model and those determined in the laboratory are 1.7459 and 1.7476 respectively. The variance and standard deviation are 6.29× 10−6and 2.51× 10−3 respectively. It was deduced that the variables are closely correlated, thus should be considered during engineering design.

The security of monitor indoor air quality using sensors is not yet widespread. However, it is an efficient way to control the toxic gazes coming from large industrial facilities when traditional instrument are not usable especially in low concentration. This paper presents the power prediction of toxic gases using neural networks MLP off-line type. Back propagation algorithm was used to train a multi-layer feed-forward network (descent gradient algorithm).The data used in this work are stemming from a system of intelligent multi-sensors analysis and signal processing in order to detect hydrogen sulfide(H2S), NO2 (nitrogen dioxide) and their mixture (H2S-NO2) in low concentration (one ppm).The successful results based on different accuracy in terms of statistical criteria, which approve the robustness of our developed model that gives a certain power prediction of electronic nose.

The most specific diagnostic test for heart diseases is the Electrocardiaogram(ECG). ECG is a graphical representation of the electrical activity of the heart. Analysis of a ECG signal starts with the detection of QRS complex. Detection of QRS complex is a difficult task as the ECG signal is frequently corrupted by powerline interference, baseline drift, motion artifact and electromyographic interference. Therefore, reliable and accurate detection of QRS complex is gaining momentum nowadays. A novel QRS detection algorithm based on Mathematical Morphology(MM) filtering and Daubechies wavelet transform has been developed in this work. MM uses its hybrid opening-closing operations for impulsive noise suppression and baseline wander removal. Daubechies3 WT is used for signal analysis since it has a shape similar to the ECG signal. R peak is extracted as a first in the feature extraction since it is having highest amplitude, followed by Q peak and S peak extraction. Heart beat rate was calculated from the R-R peak interval. From the heart rate and R-R peak interval the diagnosis of the cardiac ailments is done.
Keywords: Baseline wander, Daubechies wavelet transform, ECG, Mathematical Morphology, QRS complex.
