Abstract:

Nowadays,cloud computing services have been an embracing computing technology by some organisations, academia and entrepreneurs.Cloud Service Providers (CSP) are constrained to specific resources, missing some of the resources their clients need;this triggers the need for many and specific interconnections of homogeneous or heterogeneous computing clouds by their protocols and architectures to interoperate and share available resources among them. Clouds interconnection can be with various functions and schemes. In this study, we deployed exploratory and Design Science research approaches and Cloud-Analyst to simulate interconnections and interoperability within heterogeneous cloud service providers. The study cannot be conducted with real cloud computing environments due to the high cost that may incur and authorizations from CSPs that may not be secured. In this paper, we built a system and algorithm that can handle the variability and complexities of the different clouds during the management of inter-cloud resources. The experiment result shows that the USER-BASE (UB1) can subscribe to Data Center1(DC1) through Data Center 3 (DC3) that it initially subscribed with average time 301.05 with insignificant differences when utilizing resources from Data Center 3 (DC3).

Abstract:

Adders are the fundamental building blocks for any digital processors in VLSI design. Thepropagation delay should be low for high level applications and thus the speed is depends on the propagation delay of the full adders.Hence, the efficientdesign of the full adder is one of the major concerns in fulfilling the requirements of latest applications. As there is lot of research is carrying on full adder designs, still there is a scope of improvement. This paper aimed at design of high performance Carry Save Adder (CSA) using a modified 1-bit full adder. Initially, the basic building blocki.e., a full adder is discussed using existing and proposed Modified Gate Diffusion Input (Modified GDI) techniques. Later, by using this proposed adder the CSA have been designed and compared its performance with respect to speed, Power dissipation and area. All the proposed designs are designed in mentor graphics tools at 90nm technology.

Abstract:

Laser drilling is one of the earliest applications of lasers in materials processing. Less than 0.25mm in diameter is difficult to drill mechanically. Laser drilling offers good choices for small hole drilling, especially for hard and brittle materials, such as ceramics, but cracks appearance is one of the most difficulties that appears in this drilling. Therefore, this paper aims to study the effect of exposure time on the drilling of soda lime glass (SLG) using under water laser drilling technique. A 1.15 mm thickness SLG sheets were immersed 1mm below the water surface, then irradiated with CW CO₂ laser. The laser parameters used were (24, 25 and 26) W power, (5, 7.5 and 10) sec exposure time and (1, 2and 3) pulses. The drilled points were investigated under optical transmission microscope. Then the upper diameter, lower diameter, crack length and taper angle for these drilled holes were measured by analyzing the OM images using ImageJ software. Clearly appeared that hole diameter and the crack lengths could be controlled by the laser power and exposure time. When power or time were increased, the hole diameter increased. While the length of cracks is increased with increasing time and power. The good results found at laser power 24 W, five sec. and one pulse for hole diameter, while the minimum crack length was found at three pulses, five sec. and 24 W power.

Abstract:

Since the problem of global warming and heat waves are the burning issues and became challenge for scientists in this era. Current analysis is also an attempt to solve this problem in Karachi Pakistan. This effort is to analyze frequency distribution by using daily maximum temperature data and then to find the best fitted probabilistic model for yearly maximum temperature series to see the possible return levels of maximum temperature in Karachi.After passing through a number of goodness of fit tests the Log-Logistic [3P] distribution is found to be the best fitted model to calculate return levels. Analysis also indicates that there is a chance of getting 44.3  temperature return level in the next coming 5 years, 45.8  in coming 20 yearsand 46.5  return levels in coming 50 years return period. These return levels propose that the Government officials and planners to take notice on plantation, water supply system, to facilitate better public transport to reduce the number of vehicles, to update health system, to increase electricity production etc.The results of this analysis are also useful to agricultural and environmental research.

Abstract:

In this paper the transversal vibrations of axially moving string under structural damping are studied. The focus on the possibility of truncation method has been discussed. Governing equations of motion is modeled as second order linear homogeneous partial differential equation with constant coefficients.  The string is taken to be fixed at both ends. To construct the asymptotic approximations, the Fourier expansion method in conjunction with the two timescales perturbation method is employed. Amplitude-response of individual mode is computed under the effect of various structural damping parameter values. It is obtained that the response of individual-mode decays as the time increases. Furthermore, to investigate the applicability of truncation method, the method of characteristic coordinates and two timescales perturbation method are used in conjunction with each other. The amplitude-response subject to the specific initial conditions under the effect of various structural damping parameter values is computed. It turned out that amplitude-response decay as the time increases. Energy of the system is also computed and found to be decaying as the time progresses. From the amplitude-response of the system and individual mode amplitude-response, it is found out that the mode-truncation is allowed in the structural damping case.

Abstract:

According to the organizations like NCRB-social government and the reports of WHO, 35% women are subjected to physical harassment, abuse and violence that occur even in public places such as cabs, hospitals, public transport, public parks, in and around schools, railway-bus stands, foot paths, and worse in the very own neighbors. Changing dynamics of working environment also forces many to work in night shifts which make them to move out in vulnerable timings. In India, according to amendment to the Factories Act 1948, it was allowed under the law for women to work night shifts which enabled many women to work through shifts but also put them in risk. Most of the women are working in nightshiftsimply there is an increase in their productivity, quality and international competitiveness because of which many women tend to work nowadays and support their families. Companies always provide necessary security measures in place to ensure women safety, yet in several situations incidents happened to prove the vulnerability of them due to several attributes. Research works were being undertaken to device strategies, protocols, policies to protect women workforce from being vulnerable.   In this paper an attempt is made to make a device for the women security where the device provides the safety measure in public places, public transports such as cabs, schools, buses and company vehicle etc. We propose an advanced model, which aims to provide a safe environment for women in the society through live video streaming by embedding sensors with a processor chip. The core of the entire system is raspberry pi, Pi Camera which is used for video data which will be collected by the embedded system and sent to the cloud by wireless network. Through this device a live video camera is implemented in the device which feds the live video through a GPS module that can be used to trace the whereabouts and the issues a woman may face which can be used to rescue under distress situation.

Abstract:

Analysis of single machine infinite bus system is made by considering single Kaplan turbine-generator with exciter and governor for the small-signal stability. In this research paper a scientific approach was adopted to minimize the settling time along with the stability of the given power system. Kaplan turbine generators were predominantly implemented in hydroelectric power plants with lower heads. However, dual regulation of such turbines in the plants are renowned in the current research trends. The dual regulation of hydro-turbine is incorporated through the operation of both wicket gate and runner blade position. In a worldwide scenario Kaplan turbine-generators play a vital role in power and energy generation. Whereas the life of these generator gates or runner blades depends on speed deviations. In this context, a PID controller has been designed for the extended single machine infinite bus system to improve the speed deviation. The results of the extended single machine infinite bus system are compared with and without PID controller for the enhancement of speed deviation.

Abstract:

This paper exploring the stability to be achieved in the stochastic processes and operations which are called the autoregressive moving average and symbolized by ARMA Model(the roots of the equation should be out of this model circle.  Although these models are not stable and become stable after so many conversions and differences. These new models called the autoregressive methods for integrated moving average which is symbolized ARFIMA (p, d, q) and these differences would be integers or fractional numbers. It is worth to be mentioned that the time series which depending on the long term (long memory) so this stability achieved by snapping the fractional differences which are located within the enclosed period (-0.5, 0.5) and are referred shortly ((ARFIMA (p,d,q))). Models which are located within the enclosed period (-0.5, 0.5). This search aims to estimate the parameter of fractional differences (d), three ways by using real data from the Ministry of Environment that include the rates of air pollution in Baghdad City with Nitrogen oxides(NO²), Ozone(Oᶟ) materials…these ways are: firstly, the way logarithm periodogram chart regression method which is called (Geweke and Porter- Hudak), symbolized (GPH) Secondly, smoothed periodogram regression. Thirdly, the way that called (KASHYAP AND EOM) and it has been used the standard error squares and standard error (SD) as two scale standards among these three ways to estimate the parameter. Akaike standard has been used for choosing the best model of linear models assumed.In this study, we will be dealt with the fractional differences
