Nonunions of the subtrochanteric region of the femur after previous intramedullary nailing can be difficult to address. Implant failure and bone defects around the implant significantly complicate the therapy, and complex surgical procedures with implant removal, extensive debridement of the nonunion site, bone grafting and reosteosynthesis usually become necessary.

We report a case of hardware failure after distal femoral osteotomy (DFO) with a broken screw pulled out from the locking hole and positioned within the knee joint. Case presentation: A 57-year-old man presented to our orthopedic outpatient department with 3-months history of an unusual painful swelling at the operated area following DFO. The leakage of joint fluid from the penetrated suprapatellar pouch was assumed to be the reason for this complication.

Exception handling is the process of responding to the occurrence, during computation, of exceptions – anomalous or exceptional events requiring special processing – often changing the normal flow of program execution. It is provided by specialized programming language constructs or computer hardware mechanisms.

The emergence of electronic publishing was supposed to change all that. Yet a bloodbath of unusual proportions has taken place in the last few months. Time Warner's iPublish and MightyWords (partly owned by Barnes and Noble) were the last in a string of resounding failures which cast in doubt the business model underlying digital content. Everything seemed to have gone wrong: the dot.

The remainder of this paper is organized as follows. In Section 2 we describe the hardware used by each of the Gamma prototypes and our experiences with each. Section 3 discusses the organization of the Gamma software and describes how multioperator queries are controlled. The parallel algorithms employed by Gamma are described in Section 4 and the techniques we employ for transaction and failure management are contained in Section 5. Sec- tion 6 contains a performance study of the 32 processor Intel hypercube prototype.

Oracle provides for complete media recovery from all possible types of hardware failures, including disk failures. Options are provided so that a database can be completely recovered or partially recovered to a specific point in time. If some datafiles are damaged in a disk failure but most of the database is intact and operational, the database can remain open while the required tablespaces are individually recovered. Therefore, undamaged portions of a database are available for normal use while damaged portions are being recovered. ...

Our memory access mechanism provides hardware sup- port for unprivileged malicious software by allowing ac- cess to privileged memory regions. Malicious software triggers the attack by forcing a sequence of bytes on the data bus to enable the memory access circuits. This se- quence can be arbitrarily long to avoid false positives and the particular sequence must be agreed upon be- fore deployment.

There is no fundamental reason that a transaction must abort as aresultofanynondeterministicevent;whensystemsdochoose to abort transactions due to outside events, it is due to practical consideration. After all, forcing all other nodes in a system to wait for the node that experienced a nondeterministic event (such as a hardware failure) to recover could bring a system to a painfully long stand-still.

High-level synthesis – also called behavioral and architectural-level synthesis – is a key design technology to realize systems on chip/package of various kinds, whether single or multi-processors, homogeneous or heterogeneous, for the embedded systems market or not. Actually, as technology progresses and systems become increasingly complex, the use of high-level abstractions and synthesis methods becomes more and more a necessity. Indeed, the productivity of designers increases with the abstraction level, as demonstrated by practices in both the software and hardware domains.

Harmonic distortion problems include equipment overheating, motor failures, capacitor failure and inaccurate power metering. The topic of power system harmonics was covered for the first time 20 years ago and the first edition has become a standard reference work in this area. Unprecedented developments in power electronic devices and their integration at all levels in the power system require a new look at the causes and effects of these problems, and the state of hardware and software available for harmonic assessment.

CMOS interview questions. 1/ What is latch up? Latch-up pertains to a failure mechanism wherein a parasitic thyristor (such as a parasitic silicon controlled rectifier, or SCR) is inadvertently created within a circuit, causing a high amount of current to continuously flow through it once it is accidentally triggered or turned on. Depending on the circuits involved, the amount of current flow produced by this mechanism can be large enough to result in permanent destruction of the device due to electrical overstress (EOS)...
