Device drivers on commodity operating systems execute with kernel privilege and have unfettered access to kernel data structures. Several recent attacks demonstrate that such poor isolation exposes kernel data to exploits against vulnerable device drivers, for example through buffer overruns in packet processing code. Prior architectures to isolate kernel data from driver code either sacrifice ...

Since China has been Iran's most important trading partner in recent years, the present study has attempted to investigate the effect of bilateral real exchange rate fluctuations on the trade relationship between Iran and China during the period 1992-2017. To investigate this relationship, the business data in the export and import sectors were divided into 15 major commodity segments, and the ...

Price transmission is a critically important issue that affects market enlargement and the unification of Canadian–U.S. agriculture. This study adopts alternative frameworks to examine the nature of cross-border integration in selected meat and livestock markets. The aim is to determine the extent to which selected meat and livestock markets transmit price signals across the international borde...

Two special and important network flow problems are the maximal flow problem and the shortest path problem. Both of these problems can be solved by either the network simplex method of Chapter 9 or the out-of-kilter algorithm of Chapter 11. However, their frequent occurrence in practice and the specialized, more efficient procedures that can be developed for handling these two problems provide ...

This demo shows an implementation of 3GPP LTE (Long Term Evolution) [2] Uplink, using Sora high performance software radio platform [5]. LTE is the state-of-the-art widearea wireless technology and employs many cutting-edge physical layer designs, including Turbo Coding, MIMO, SCFDMA and OFDMA [3, 4]. This demo shows a LTE Uplink implementation based on Release 8 3GPP 36 Series specifications i...

This research presents the Enhanced Commodity Forward Buy (ECFB) heuristic, a new method for commodity purchasing, which allows strategic forward buying of commodities for products that include commodity components or materials. The Enhanced Commodity Forward Buy addresses limitations of existing methods by considering stochastic demand and stochastic commodity prices for products that contain ...
