    Abstract To provide education and particularly providing practical educational experiences to the students in the field of computing and information technology related courses including practical experience in the field of Networking, System Administration, and Operating Systems needs a lot of resources for the institution. Because this level of technical education can’t be provided only theoretically, students also need hands-on practical experience, and providing practical experience faces a lot of problems such as lack of funding and physical space, risks and threats to the network environment when we attempt to provide real, physical laboratory for experiments. This problem can be solved by developing a virtual environment for delivering students practical education. In this report we will look into different technologies used for virtualization today and do a comparative study. We will also explore some of the institutions, which are using virtual machines based environment to provide students practical experience in the field of computing and information Technology. And see how peoples are getting benefits from using virtual machines. We present how networks of virtual machines can be beneficiary for computing and information technology student and institutions by providing necessary environment in virtual network

    With the rapid expansion in the use of internet services such as web browsing, mails, audio and video files downloading, servers' needs to manage with greater strain resources and actions. Demand for total number of clients supported by the servers has increased significantly. With a continues increase in total number of users and as a result escalating work load makes businesses uncertain about their actions with the passage of time. In addition rapid response and 24 hours availability becoming mandatory necessities for many big critical businesses applications as a result, the necessity of providing support for extremely expandable, sustainable and available services is becoming crucial. Linux Virtual Server is the best solution for providing businesses such critical services. Linux Virtual Server is an open source tool, used to establish expandable, sustainable and highly available server using a number of real servers and a front end Director. Linux Virtual Server has the ability to balance Load of a number of network services amongst several real servers using different scheduling algorithms and packet forwarding methods which suits bests for services and hardware limitations. In this project a web services Linux Virtual Server will be established using NAT (Network Address Translation) packet forwarding method and using three different scheduling algorithms, Round Robin, Weighted Round Robin and least Connection. With each scheduling algorithm number of test setup will be conducted by varying number of real servers used in the Linux Virtual Server Cluster, varying HTTP traffic through using different size of data files downloaded from the real servers and also varying number of request send per second

    The objective of this study is to examine the impact of Management by Objectives (MBO) on employee’s performance, encouragement and motivation, self-confidence and contentment in public sector organizations, when they introduced MBO approach within an organization. We achieved our objective after review numerous and extensive literature and found that MBO improved the performance, efficiency, effectiveness and employees’ confidence in the public sector organizations. The employees who participate in management by objectives program (MBO) know what exactly management is expecting from them. They better know about the organizational goals, their morale, performance, and job satisfaction are high. They are also more confident than those employees who don’t participate in MBO program. Management by Objectives was recommended as a method to enhance administration efficiency for over sixty- years. Drucker (1954) was first introduced this term to setting organizational objective with the systematic way that would support to boost the organization satisfaction and employee’s performance within the organization. The quantitative study is not possible because of limited time. A large number of private sector organizations have already introduced MBO to improve the management and employee’s performance. This study gives support to introduce MBO in the public sector agencies. In summary, the impact of MBO system depends strongly on the design and implementation of its features. If it based on the standard, good practice and principle, then MBO can increase the performance effectively and efficiently in public sector firms.

    The main objective of this paper is to highlight the importance of the financial stability of the global fi nancial system particularly after the recent global financial crisis of 2008-09. The major causes of different financial crises possess the same pattern of greed among investors, inefficiency of government regulators, central banks and other stakeholders. They have miserably failed to fix the structural problems such as control of excessive debt lending, enforcement of eff ective regulations, prohibition of speculative business activities and unethical business practices in the global financial system. Islamic financial system, whose size of global assets crossed the mark of US$ 2.1 trillion by the end of 2015, which is relatively very small as compared to the conventional financial system, is rapidly growing as an alternative system. It prohibits unethical economic activities such as speculative derivative trading, uncontrolled excessive debt lending and promotes an interest-free financial system based on profit, loss and risk sharing principles. This paper concludes that global financial stability could only be achieved if proper corrective actions were taken. It also shows that the Islamic financial system was less affected by the recent global financial crisis compared to the conventional financial system because it imposes strict rules and prohibits investments in toxic assets.Glavni cilj ovog rada je naglasiti važnost financijske stabilnosti svjetskog financijskog sustava, naročito nakon nedavne svjetske financijske krize 2008.-2009. Glavni razlozi raznih financijskih kriza uvijek su imali iste značajke pohlepe investitora, neučinkovitosti propisa, središnjih banaka i ostalih dionika. Potpuno je neuspješno bilo rješavanje strukturnih problema, poput kontrole prevelikog zaduživanja, provedbe učinkovitih propisa, zabrane spekulativnih poslovnih aktivnosti i neetičkih poslovnih praksi u svjetskom financijskom sustavu. Islamski financijski sustav čija je svjetska imovina prešla brojku od 2.1 bilijuna američkih dolara krajem 2015. godine, što je relativno malo u usporedbi s konvencionalnim financijskim sustavom, ubrzano raste kao alternativni sustav. On zabranjuje neetične gospodarske aktivnosti poput spekulativnog trgovanja izvedenicama, nekontrolirano prekomjerno zaduživanje te promiče beskamatni financijski sustav koji se temelji na načelima profita, gubitka i podijeljenog rizika. U radu se zaključuje da se svjetska financijska stabilnost može postići samo ako se poduzmu prave korektivne aktivnosti. U radu se pokazuje kako je islamski financijski sustav manje pogođen nedavnom svjetskom financijskom krizom od konvencionalnog financijskog sustava, jer nameće stroga pravila i zabranjuje ulaganje u toksičnu imovinu

    The paper describes a study of canal and supplemental ground water used by 544 farmers for wheat crop in the Rechna Doab catchment of Pakistan. The main objective was to assess the on-farm financial gains through conjunctive water use. For econometric analysis, a linear relationship between the wheat production and different determinant variables was assumed. The results highlighted the problem of increased use of tubewells water in the saline zones that had resulted in the deterioration of the groundwater quality and led to the problem of permanent upconing of saline groundwater. Conjunctive water management increased the farm income by about Rs. 1000 and 5000 per hectare compared to only using the canal and tubewell water, respectively The results of financial analysis show that the net-gains were 30 percent higher on the farms using conjunctive water management as compared to the farms using only tubewell irrigation.Environmental Economics and Policy, Resource /Energy Economics and Policy,

    Pakistan: State Autonomy, Extraction, and Elite Capture—A Theoretical Configuration

    ―When groups are adequately stated, everything is stated!‖1 Management of actions and interest groups has historically been sovereign‘s existentialist imperative. The paper revitalizes philosophical state autonomy debate and then narrows down its focus to capture extractive antics of as erratic a state as Pakistan. A typology of factions – captioned as Elites – operative in extractive realm of Pakistan is developed to round them in theory, identify their properties, and lay bare mechanics of intra-elite and elite-non-elite transactions. The paper seminally develops the rational actor dilemma confronting Pakistani elites and identifies the modes through which the dilemma plausibly resolves itself. The transactional engagement between Pakistan‘s internal and external rational actors is dissected to theorize that Pakistan essentially is an equilibrium consensus subsistence state thereby opening up vast vistas for future research. The paper concludes with the glum finding that Pakistan in its current essence and manifestation is fundamentally a captive state – beholden to elites of Pakistan.
