Industry 4.0 describes the future production of workpiece in job shop as: the workpiece is a smart one; it knows the details of how to manufacture itself; and it can communicate with manufacturing environment to support its own machining processes. This means that the production of workpiece places more emphasis on the smart realization of the process level in Industry 4.0. However, how to implement the production scenario based on existing technologies has not yet been well studied. On account of this, this article aims to study how to use existing technologies in job shop such as digital twins, Internet of Things (IoT), Cyber-physical Production System (CPPS), etc., to realize the workpiece-driven process-level production. The process-level production of a workpiece is divided into three stages according to the different manufacturing resources involved. On this basis, the production of the workpiece in digital twin job shop is divided into process level, operation level, and IoT/sensor level. Firstly, the manufacturing requirements at process level are generated according to production planning and process sheet. And these requirements are written into RFID tag of the workpiece. The workpiece dynamically interacts with different workstations via RFID reader/antenna in order to complete the manufacturing requirements. Secondly, based on the tag data, the interaction model of operation level, and IoT/sensor level CPPSs is given. Thirdly, at IoT/sensor level, the RFID devices are treated as a CPPS to track the manufacturing resources. And different smart sensors are used as independent sensor CPPSs to monitor the running status of machine tool. The RFID and sensor CPPSs are triggered by operation level CPPSs. Finally, a digital twin job shop is taken as an example to illustrate the feasibility of the proposed models and methods.

The report offers an account of archaeological and conservation work carried out at the site. Excavations in the central part of the site (Sector F) were continued for the fourth season in a row. Exploration of remains of early Roman houses led to the discovery of a well preserved multicolored triclinium mosaic floor with a floral and geometric design. A large assemblage of fragments of polychrome marble floor tiles, recorded in the house collapse, showed the scale of importation of decorative stone material from various regions of the Mediterranean. Overlying the early Roman strata was direct evidence of intensive construction work carried out in the vicinity in the form of large-scale kilnworks, supplying lime most probably for the building of the late Roman bath and cistern. Included in the presentation is a brief review of the limited conservation work that was conducted in the complex of late antique auditoria.

Abstract Test engineers and failure analyst familiar with random access memory arrays have probably encountered the frustration of dealing with address descrambling. The resulting nonsequential internal bit cell counting scheme often means that the location of the failing cell under investigation is nowhere near where it is expected to be. A logical to physical algorithm for decoding the standard library block might have been provided with the design, but is it still correct now that the array has been halved and inverted to fit the available space in a new processor chip? Off-line labs have traditionally been tasked with array layout verification. In the past, hard and soft failures could be induced on the frontside of finished product, then bitmapped to see if the sites were in agreement. As density tightened, flip-chip FIB techniques to induce a pattern of hard fails on packaged devices came into practice. While the backside FIB edit method is effective, it is complex and expensive. The installation of an in-line Dual Beam FIB created new opportunities to move FA tasks out of the lab and into the FAB. Using a new edit procedure, selected wafers have an extensive pattern of defects 'written' directly into the memory array at an early process level. Bitmapping of the RAM blocks upon wafer completion is then used to verify correlation between the physical damaged cells and the logical sites called out in the test results. This early feedback in-line methodology has worked so well that it has almost entirely displaced the complex laboratory procedure of backside FIB memory array descramble verification.
