The LEP energy upgrade up to fi =189 GeV has allowed us to extend substantially the potential of searches for new physics. Results on searches for Higgs bosoms and supersymmetric particles obtained by the ALEPH, DELPHI, L3, and OPAL experiments are reported. No evidence of any signal is observed. Therefore, new limits on the Higgs boson masses as well as on the masses of the various supersymmet...

We would like to congratulate Fruchter et al 1 for their ingenious, effective, and minimally invasive way of treating the very challenging condition of bronchopleural fi stulas as reported in a recent issue of CHEST (March 2011). However, because we were cited in their work, we must make a correction. The misunderstanding is that our fi rst publication was a case report of our fi rst patient (5...

The velocity of global business change is challenging the management of enterprise resource planning (ERP) systems. The growing speed of business changes mandates that software be managed with flexibility and agility. At the same time, system implementation success depends on an effective project management (PM) process. Notable problems associated with the implementation of an enterprise syste...

A major advance in development of project selection tools came with the application of options reasoning to R&D. The options approach to project valuation seeks to correct the deficiencies of traditional methods of valuation through the recognition that managerial flexibility can bring significant value to a project. The main concern is how to deal with non-statistical imprecision we encounter ...

This paper proposes a risk-based process strategy decision-making approach. To improve the flexibility in applying the Value-Based Software Quality Achievement (VBSQA) process framework, we embed the risk-based process strategy decision-making approach into the VBSQA process framework. It facilitates project managers to tailor the VBSQA process framework to different project business cases (sch...

Forest plantations with Toona ciliata are presented as economically viable thanks to the suitability of their wood for high-quality niche products. However, this study verifies whether investment projects in T. incorporation managerial flexibility. We apply technical-economic coefficients from forest over a 15-year planning horizon, considering project an underlying asset and price only source ...

Introduction In examining wireless-internet technologies (Wi-Fi), several ethical issues are exposed. While the unauthorized use of Wi-Fi is illegal in a few select cases, what is considered permissible still varies from state to state. What does not vary, however, is the fact that individuals are going to great lengths to locate unsecured wireless access points whether it is for their own bene...

In this paper the problem of obtaining the degree of flexibility that maximizes the total profit in an existing process flowsheet is addressed. Assuming a linear model for the process and given probability distribution functions for the uncertain parameters, the curve relating the expected revenue to the flexibility index is generated. An efficient stochastic optimization method is developed fo...

1. Given topological spaces X and Fand two continuous mappings ƒ o and jfi from X to F (denoted by fo, fi : X—> F) we say that ƒ o is homotopic to jfi (denoted by fo—fi) if there exists a continuous family of continuous mappings ht: X—+Y for O^t^l such that ho=fo and h =/ i . Intuitively fo<^fi if the map ƒ o can be continuously deformed into the map jfi. I t is easily seen [4; 7] that the rela...
