Brain Signal Analysis of Meditation and its Impact on Concentration and Diluted Modes[ ]


Procrastination occurs when the brain switches from one mode to another to meet the situational requirements. Procrastination can lead to frustration if a subject lacks experience to commute between two modes of different thught. The primary cause stems from lack of assurance in one’s ability to perform a task. To alleviate this problem, researchers have found a way to “fool” the brain from negative to positive affirmation. In this paper, we show brain signal changes occurring during people’s interaction with non-familiar situations (diluted mode), and their performance during familiar activity (concentrated mode). We observe cerebral cortex signals from the participants using electroencephalography (EEG). Participants were induced to switch from a concentrated mode to a diluted mode by means of a narrow questionnaire. EEG signals revealed a shift from ± 200 µV (naturally occurring during concentrated mode) to twice the initial signal (indicating a shift to diluted mode). Investigators then supplied participants with techniques to overcome their shock upon questioning. Brain signals returned to normal levels.

Print Quality Control Management for Papers Containing Optical Brightening Agents[ ]


Optical brightening agents (OBAs) or fluorescent whitening agents (FWAs) are chemicals added to paper during the papermaking process to increase the brightness of paper (chemical additives that increase the reflection of blue light (caused by ultraviolet light with a wavelength below 400nm) for the correction of a natural yellow color of paper pulp). Papers with agents for optical brightening are often represented on the market. The aim of this paper is to show that colors reproduced on paper with (Iggesund Incada Silk, 220g/m2) and without (Iggesund Incada Silk T, 205g/m2) agents for optical brightening, are different during the same printing conditions. Standard ISO 13655 (Spectral Measurement and Colorimetric Computation for Graphic Arts Images) defines the “M” series of illumination, which provides color management in these conditions.

Separation Harmonics to Discern Broken Bar Fault from Load Torque Oscillation in Three Phase Induction Motor[ ]


This paper presents separation harmonics to discriminate rotor failure from low frequency load torque oscillations in three phase in-duction motors. The most common method for detecting broken rotor bar faults is to analyze the corresponding sidebands through motor current signature analysis (MCSA). If a motor is subjected to load fluctuation, then the oscillation related sidebands exhibit similar behaviors as well. Particularly, when the load fluctuation frequency is close or equal to that of broken bars, the stator current spectrum analysis can be misleading. In this study, torque and motor phase voltage waveforms are exhaustively analyzed to discriminate broken rotor bar fault from low frequency load torque oscillation in three phase induction motors. In order to extract and justify the separation patterns, 2-D Time Stepping Finite Element Method (TSFEM) is used. The simulation and experimental results show that the proposed approach can successfully be applied to fault separation process in star connected motors.

INVESTIGATING THE EFFECT OF USING RECYCLED MATERIALS IN HIGHWAY CONSTRUCTION[ ]


Recycled concrete and marble materials from construction and demolition operations are disposed in landfill sites. Concrete accounts for around 60% of waste in the U.S. in addition, landfill area and the guidelines govern their procedure becomes more serious. Environmental, it is important to recycle the landfill materials when it is possible as it sustain the natural resources to the coming generations. Moreover, the authorizing process for aggregate quarries has become a difficult task for contractors due to increased environmental regulations to sustain the natural resources. The aims of this paper are to evaluate the alternative usage of the recycled concrete and marble as well as marble dust for different road layers. The experimental program was carried out through different stages starting by evaluating the use of course aggregate in asphalt pavement mix (not in this research scope). The second stage was to develop different blends (S1 to S9) between dolomite stone, lime stone, recycled marble, and recycled concrete to be evaluated as a base and subbase layer. Finally marble dust was tried instead of lime dust in asphalt pavement mix. The outcomes of the second stage presented in this paper showed that all tried types of recycling material can be used as either a base course and or a subbase course. In addition it saves between 12.5 to 53.8% of the total cost. Furthermore, the marble dust enhanced the mix stability better than lime dust from 1680 lb to 1927 lb.

A Best Effort Heuristic Algorithm for Scheduling Timely Constrained Tasks in the Cloud[ ]


The size and complexity of Cloud systems are growing more rapidly, and hence, the management of these cloud systems and its resources is a major research area. Resource provision with respect to SLA (Service Level Agreement) is directly tied up with customer satisfaction like providing the service with less Cost with less finshing time, for that, cost effective scheduling with real time constraints are major challenges in adopting cloud computation. In this work we propose a two-stage scheduling technique for timely constrained cloud computing services. The first stage is in charge of producing a scheduling sequence, whereas the second stage aims to dispatch tasks to computing nodes of a cloud computing system. The two stages are independent of one another and; therefore, one can change a policy in one stage without configuring another one. The main goal of the proposed work is to improve user satisfaction, to balance the load efficiently and to bolster the resource utilization and provide the service with the competitive cost at the same time.

Study on the Hydrodynamics of Stirred Vessels[ ]


In this study, the mass transfer coefficient of oxygen in distilled water was studied with respect to various parameters such as impeller type and size, flow rate of air and agitation speed of the motor. When studying the effect of impeller size with three different sizes of sawtooth, the kLa value reached 0.0135 s-1 for the large size impeller with a diameter of 83.6 mm. On the other hand, the medium and small impellers reached kLa values of 0.0118 s-1 and 0.0069 s-1, respectively. Furthermore, experiments on effect of air flow showed that the value of kLa increased as the flow of air introduced to the system increases. A range of air flow rate from 0.16 to 0.52 m3/h was experimented for different types of impellers. It was noticed that the best result was recorded with Rushton turbine at a speed of 500 rpm and flow of 0.52 m3/h, where the value of kLa reached is 0.0262 s-1. While CD-6, paddle and sawtooth at the same mentioned speed and flow rate gave kLa values of 0.0232 s-1, 0.0217 s-1 and 0.0135 s-1, respectively but still CD-6 consumes less power than Rushton turbine as well established in literature. For the effect of various agitation speeds, it was found that as the speed increases the dispersion of gas bubbles enhanced in the vessel. A range of impeller speed from 300 to 700 rpm was experimented with different type of impellers. The best value of kLa of 0.0389 s-1 was obtained at a Rushton turbine unlike the kLa of CD-6 which was 0.4 s-1. Due to advantages of CD-6, the kLa value of Rushton turbine is smaller than the kLa of CD-6. Moreover, paddle and large sawtooth diameter impeller scored low values of kLa of about 0.0231 s-1 and 0.0281 s-1, respectively.
