Efficient charged particle tracking and high momentum resolution are central performance requirements of the CBM Silicon Tracking System (STS). The aim of the ongoing layout studies is to design a highly granular and lowmass detector system which can track up to 1000 charged particles that are typically generated in one central Au+Au collision at 25 GeV/u projectile energy. A low-mass detector ...

This paper proposes a new feature point detector which uses a wedge model to characterize corners by their orientation and angular width. This detector is compared to two popular feature point detectors: the Harris and SUSAN detectors, on the basis of some defined quality attributes. It is also shown how feature points between widely separated views can be matched by using the information provi...

A 2D photon-counting X-ray detector system with 1.4 kHz frame rate and 55 μm spatial resolution has been developed and commissionned on ESRF beamlines. The system called MAXIPIX (Multichip Area X-ray detector based on a photon-counting PIXel array) consists of a detector module implementing up to five MEDIPIX-2 or TIMEPIX photon-counting readout chips, a custom readout interface board and a Lin...

This paper develops a reduced complexity quasi-1D detector for optical storage devices and digital communication system. Superior performance of the proposed detector is evidenced by simulation results.

This paper defines the fault-tolerant mutual exclusion problem in a message-passing asynchronous system and determines the weakest failure detector to solve the problem. This failure detector, which we call the trusting failure detector, and which we denote by T , is strictly weaker than the perfect failure detector P but strictly stronger than the eventually perfect failure detector P . The pa...

During the year of 2007, the Large Hadron Collider (LHC) and its four main detectors will begin operation with a view to answering the most pressing questions in particle physics. However before one can analyse the data produced to find the rare phenomena being looked for, both the detector and readout electronics must be thoroughly tested to ensure that the system will operate in a consistent ...

This paper investigates the amount of information about failures needed to solve the predicate detection problem in asynchronous systems with crash failures. In particular, we show that predicate detection cannot be solved with traditional failure detectors, which are only functions of failures. In analogy to the definition of failure detectors, we define a failure detection sequencer, which ca...

Uniform Reliable Broadcast (URB) is a communication primitive that requires that if a process delivers a message, then all correct processes also deliver this message. A recent paper [HR99] uses Knowledge Theory to determine what failure detectors are necessary to implement this primitive in asynchronous systems with process crashes and lossy links that are fair. In this paper, we revisit this ...
