Deadlock problems in flexible manufacturing systems (FMS) have received more and more attention in the last two decades. Petri nets are one of the more promising mathematical tools for tackling deadlocks in various resource allocation systems. In a system modeled with Petri nets, siphons are tied to the occurrence of deadlock states as a structural object. The book systematically introduces the novel theory of siphons, traps, and elementary siphons of Petri nets as well as the deadlock control strategies for FMS developed from it. Deadlock prevention methods are examined comparatively. The many FMS examples presented to demonstrate the concepts and results of this book range from the simple to the complex. Importantly, to inspire and motive the reader’s interest in further research, a number of interesting and open problems in this area are proposed at the end of each chapter.

A deadlock occurs when there is a cyclic dependency between two or more threads, or processes, for some set of resources within operating system environment. A set of processes is deadlocked if each process is waiting for an event that only another process in the set can cause. My thesis aims at creating a tool, which can be used by an application developer for detecting the occurrence of a deadlock. It also helps the developer in analyzing the cause of deadlock, since the project provides him with information, such as the deadlocked processes and the resources causing it. The developer can also view the log file, which is generated by this tool to study the sequence of events, such as locking or unlocking of the resources. The outline of the project is as follows: A wrapper function dd_semop has been developed around the system call semop. An application program has to include a header file "libdeadlock.h" in order to use this wrapper functionality. A daemon process has also been developed dl_mgmt, which carries out the major functionality for deadlock detection and recovery. The wrapper function communicates with the daemon process, which runs in the background and actually verifies whether a lock can be granted or not and communicates back the possibility of a deadlock. Once the tool provides the output and depending on the users feedback to it, the tool provides a mechanism to continue execution without deadlock. Thus, this research project provides a comprehensible tool to study and manage deadlocks in a Linux flavor known as Fedora. Deadlock is thus a potential problem. Timely detection of deadlock and its cause are essential for resolving the error and maintaining forward progress.

Deadlock is a novel about the impact of the Supreme Court today . . . and about imminent, real-life choices that will shape both its future and that of our nation.She is a Supreme Court Justice. She is an atheist.And she is about to encounter the God of the truth and justice she has sworn to uphold.For years, Millicent Hollander has been the consistent swing vote on abortion and other hot-button issues. Now she’s poised to make history as the first female Chief Justice of the United States Supreme Court. But something is about to happen that no one has counted on, least of all Hollander: a near-death experience that will thrust her on a journey toward God.Skeptically, fighting every inch of the way, Hollander finds herself dragged toward belief in something she has never believed in—while others in Washington are watching her every step. Too much is at stake to let a Christian occupy the country’s highest judicial office. Even as Hollander grapples with the interplay between faith and the demands of her position, and as she finds answers through her growing friendship with Pastor Jack Holden, a hidden web of lies, manipulation, and underworld connections is being woven around her. It could control her. It could destroy her reputation. Unless God intervenes, it could take her out of the picture permanently.

Hutch is a newspaper columnist, single dad . . . and last defense against a lunatic's high-tech killing machine. Special Forces veteran-turned-billionaire Brendan Page has some dirty not-so-little secrets. He's built an empire on supplying futuristic weapons and highly trained soldiers to the world's most powerful armies. But he's saved his most destructive weapons for himself. John Hutchinson, a Denver newspaper columnist and avid bow-hunter, has figured out the truth about Brendan Page and is determined to bring him down. But he's up against a warmonger linked to assasinations, kidnappings, and terrorist activities. Hutch quickly uncovers a plan that seems unfathomable in its recklessness and loss of life. Yet he's just one man up against impossible odds--with no Plan B. Thankfully, it's just the kind of environment Hutch thrives best in . . . if he can survive the next three days. Deadlock will grab you from the riveting first page to its white-knuckle climax. "With a blistering pace and irresistable characters, Deadlock is the best of high-octane suspense." - Gayle Lynds, New York Times best-selling author of The Last Spymaster

High-octane adventures continue in the eighth book of the H.I.V.E. series, and the team of supremely talented criminals is forced to question everything they know about life as villains. Otto and Raven are desperate to rescue their friends from the clutches of Anastasia Furan, head of the evil Disciples organization. First they must track down the location of the Glasshouse, the prison where Furan trains children to become ruthless assassins. But Otto is also being hunted. In the three months since his “expulsion” from H.I.V.E., The Artemis Section—an elite intelligence division that goes after the toughest targets and reports only to the US president—has had an opportunity to locate him. Set against the backdrop of a daring high-tech prison break, nothing is quite as it seems in Deadlock.

In Iris Johansen's Deadlock, Emily Hudson is a renowned archaeologist who travels the world to save priceless artifacts from theft or destruction. Her best friend and partner, Joel Levy, is always at her side—until one day, when her entire crew comes under attack. Joel and Emily are held hostage by a sadistic captor who is determined to find the missing link to a legendary treasure. For weeks they struggle to survive against terrifying odds, pushed to their limits—and beyond... John Garrett has worked for the CIA, British intelligence, and whoever else was willing to pay for his services. This time, a Washington operative hands him what at first appears to be just another assignment: to track down, and save, Emily and Joel. But it quickly becomes much more, especially when Garrett finds himself drawn to someone as dauntless and bent on revenge as Emily. Soon, they're catapulted into an astonishing adventure in which nothing—and no one—is what it seems. And lives hang in the balance as one man and one woman unravel the explosive truth behind a conspiracy hidden for generations.

Complex computer-integrated systems offer enormous benefits across a wide array of applications, including automated production, transportation, concurrent software, and computer operating systems, computer networks, distributed database systems, and many other automated systems. Yet, as these systems become more complex, automated, distributed, and computing-intensive, the opportunity for deadlock issues rises exponentially. Deadlock modeling, detection, avoidance, and recovery are critical to improving system performance. Deadlock Resolution in Computer-Integrated Systems is the first text to summarize and comprehensively treat this issue in a systematic manner. Consisting of contributions from prominent researchers in the field, this book addresses deadlock-free models and scheduling, detection and recovery methods, the formulation of dynamic control policies, and comparison and industrial benchmark studies that evaluate various approaches. The editors lay the foundation for exploring deadlock issues with a typical example of an automated manufacturing process, illustrating three primary modeling methods (digraphs, Petri nets, and automata) and comparing their respective advantages and disadvantages. Providing all of the important models and resolution approaches, this book is the complete guide for electrical and control engineers and manufacturing, intelligent, and network systems designers to prevent and manage deadlock issues in their systems.
