  • Mobile network operators will meet many challenges in the coming years. It is expected that the number of people connected, wireline and wireless, will reach five billion by 2015. At the same time, people use more wireless services and they expect similar user experience to what they can now get from fixed networks. Because of that we will see a hundred-fold increase in network traffic in the near future. At the same time markets are saturating and the revenue per bit is dropping.

  • We present in this article, as a part of aspectual operation system, a generation system of iterative expressions using a set of operators called iterative operators. In order to execute the iterative operations efficiently, we have classified previously propositions denoting a single occurrence of a single event into three groupes. The definition of a single event is given recursively.

  • What can’t be measured can’t be improved. Even though Supply Chain Management is the most talked about topic today, currently no tool is available to measure any manufacturing organizations’ supply chain efficiency. Unlike productivity and or quality measurement, where the parameter can be measured objectively and expressed in unit or ratio, supply chain measurement is currently more of a qualitative statement.

  • One of the keys to using the logframe successfully is understanding what the definitions mean in operational terms, and in particular the relationship between Results and Project Purpose. Although managers are accountable for delivering the Results, they cannot control the behaviour of the target group. Achievement of the Project Purpose requires a ‘beneficiary response’ whereby the target group uses project services and in doing so derives a benefit for themselves. However, this does not mean that project managers are not responsible for achieving the Project Purpose.

  • This paper proposes a new approach for ranking efficiency units in data envelopment analysis as a modification of the super-efficiency models developed by Tone. The new approach based on slacks-based measure of efficiency (SBM) for dealing with objective function used to classify all of the decision-making units allows the ranking of all inefficient DMUs and overcomes the disadvantages of infeasibility.

  • The goal of interactive machine translation is to improve the productivity of human translators. An interactive machine translation system operates as follows: the automatic system proposes a translation. Now, the human user has two options: to accept the suggestion or to correct it. During the post-editing process, the human user is assisted by the interactive system in the following way: the system suggests an extension of the current translation prefix. Then, the user either accepts this extension (completely or partially) or ignores it. ...

  • An operations manager uses job design techniques to structure work to meet the physical and behavioral needs of the employee. Work measurement methods are used to determine the most efficient means of performing a given task, as well as to set reasonable standards for performing it. Work performance standards are important to the workplace so accomplished can be measured and evaluated. Standards permit better planning and costing and provide a basis for compensating the work force and even providing incentives.

  • From a processing point of view, however, flexible categorial systems are problematic, since they introduce spurious ambiguity. In this paper, we present a flexible categorial grammar which makes extensive use of the product-operator, first introduced by Lambek (1958). The grammar has the property that for every reading of a sentence, a strictly left-branching derivation can be given. This leads to the definition of a subset of the grammar, for which the spurious ambiguity problem does not arise and efficient processing is possible. ...

  • In this paper, we present two vector-level software algorithms which essentially eliminate such bit-wise operations for Gaussian normal bases. Our analysis and timing results show that the software implementation of the proposed algorithm is faster than previously reported normal basis multiplication algorithms.

  • This chapter discusses how users perceive user convenience, how an operating system achieves efficient use of resources, and how it ensures security and protection. It introduces the notion of effective utilization of a computer system as the combination of user convenience and efficient use that best suits a specific computing environment. It also describes the fundamental tasks involved in management of programs and resources, and in implementing security and protection.

  • This chapter is devoted to the fundamentals of memory management. It begins by discussing how memory protection is implemented in the hardware by using special registers in the CPU. It then discusses how efficient use of memory is achieved by reusing memory released by a process while handling subsequent memory requests, and how techniques for fast memory allocation and deallocation may cause memory fragmentation.
