Artemis was one of the most widely venerated of the Ancient Greek deities. Her Roman equivalent is Diana. Some scholars believe that the name, and indeed the goddess herself, was originally pre-Greek. Homer refers to her as Artemis Agrotera, Potnia Theron: "Artemis of the wildland, Mistress of Animals". The Arcadians believed she was the daughter of Demeter.In the classical period of Greek mythology, Artemis was often described as the daughter of Zeus and Leto, and the twin sister of Apollo. She was the Hellenic goddess of the hunt, wild animals, wilderness, childbirth, virginity and protector of young girls, bringing and relieving disease in women; she often was depicted as a huntress carrying a bow and arrows. The deer and the cypress were sacred to her. In later Hellenistic times, she even assumed the ancient role of Eileithyia in aiding childbirth. Wikipedia.

A fluid working machine of the type comprising working chambers of cyclically varying volume and low and high pressure valves to regulate the flow of working fluid into and out of the working chamber, from low and high pressure manifolds, in which the valves are electronically controlled on each cycle of working chamber volume, by way of valve actuation signals, to determine the net displacement of working chambers. Additional valve actuator signals are generated in response to determination that a valve or working chamber has been inactive to adapt the valve to operate more reliably when subsequently actuated, but without significantly altering the net displacement of working chambers.


A hydraulic machine includes a rotation shaft (22), a plurality of pistons (26) configured to reciprocate in a period corresponding to a single rotation of the rotation shaft (22), a plurality of cylinders (24) forming a plurality of working chambers (25) with the plurality of pistons (26), a state-switch unit for switching a state of each working chamber (25) between an active state in which energy is converted between rotation energy of the rotation shaft (22) and pressure energy in the working chamber (25) and a non-active state in which the energy is not converted, and a controller (50) for controlling the state-switch unit. The controller (50) is configured to fix a state of at least one of the working chambers (25) to the non-active state, the at least one working chamber corresponding to a time phase different from the time phase of reciprocation of the piston of an abnormal working chamber with a malfunction, or to reduce a frequency of switching the state of the at least one working chamber to the active state. The corresponding method of operating a hydraulic machine is also disclosed.


Industrial system with synthetically commutated variable displacement fluid working machine An injection moulding system, water jet cutting machine or other industrial system has a synthetically controlled variable displacement fluid working machine which outputs hydraulic fluid to one or more fluid consumers, such as rams or hydraulic motors, through hydraulically stiff fluid retaining volumes and receives hydraulic fluid back from one or more fluid consumers (111, 112) through the same or other said hydraulically stiff fluid retaining volumes (101, 102). Individual piston cylinder assemblies can be allocated to different outputs. There may be no valve between the machine and the consumers. A working chamber of the machine can be caused to undergo a motoring cycle to enable the machine to output more power than is received from a motor driving the machine. An accumulator can be used to provide a source of hydraulic compliance. The machine can be controlled using pressure control, flow control, feed forward control or variable power/variable power limit control.

COMPARE aims to harness the rapid advances in molecular technology to improve identification and mitigation of emerging infectious diseases and foodborne outbreaks. To this purpose COMPARE will establish a One serves all analytical framework and data exchange platform that will allow real time analysis and interpretation of sequence-based pathogen data in combination with associated data (e.g. clinical, epidemiological data) in an integrated inter-sectorial, interdisciplinary, international, one health approach. The framework will link research, clinical and public health organisations active in human health, animal health, and food safety in Europe and beyond, to develop (i) integrated risk assessment and risk based collection of samples and data, (ii) harmonised workflows for generating comparable sequence and associated data, (iii) state-of-the-art analytical workflows and tools for generating actionable information for support of patient diagnosis, treatment, outbreak detection and -investigation and (iv) risk communication tools. The analytical workflows will be linked to a flexible, scalable and open-source data- and information platform supporting rapid sharing, interrogation and analysis of sequence-based pathogen data in combination with other associated data. The system will be linked to existing and future complementary systems, networks and databases such as those used by ECDC, NCBI and EFSA. The functionalities of the system will be tested and fine tuned through underpinning research studies on priority pathogens covering healthcare-associated infections, food-borne disease, and (zoonotic) (re-) emerging diseases with epidemic or pandemic potential. Throughout the project, extensive consultations with future users, studies into the barriers to open data sharing, dissemination and training activities and studies on the cost-effectiveness of the system will support future sustainable user uptake.


A poppet valve (50) includes: a valve seat (71); a poppet (60) disposed so as to face the valve seat (71); an actuator (55) for driving the poppet (60); and a first valve casing (51) in which the actuator (55) is accommodated. The first valve casing (51) or a plate member (80) interposed between the poppet (60) and the first valve casing (51) includes a contact surface capable of partially contacting an end surface of the poppet opposite to the valve seat (71). At least one of the contact surface or the end surface of the poppet has an uneven section which forms a space between the end surface of the poppet and the plate member or the first valve casing while the end surface of the poppet is in partial contact with the contact surface. A total angular range, in the circumferential direction of the poppet, in which the space intersects with a line parallel to a radial direction and passing through a center axis of the poppet, is not less than 180 angular degrees.

This SBIR consists of the development of a dual-frequency-band imaging radar operating at Ka-band and L-band with ground moving target indicator (GMTI) and Video-SAR capabilities for use on small manned and unmanned aircraft. Intelligence, Surveillance, and Reconnaissance (ISR) missions will benefit from the flexible multi-band SAR that will handle several missions with significantly reduced size, weight, and power (SWaP). In Phase II a prototype radar will be built and tested which meets the performance specifications and the limited SWaP profile. At ARTEMIS we will make use of our decades of experience in radar design and manufacture in building a rugged, pod-mount radar system which can be used on the Shadow 200 and similar aircraft. At Ka-band, the radar will have four channels and make use of space-time adaptive processing (STAP) for GMTI detection of moving targets, particularly dismounts. Also, very high resolution Ka-band SAR imagery will be available for target detection and identification, as well as coherent change detection. At L-band, a very different view of the world is provided with the advantages of a long-wavelength sensor with a wide swath and fully polarimetric capabilities. This combination of features presents a significant leap in radar technology for small aircraft.

A belt as an endless traction device for conveyor belts of agricultural machines, the belt being made of a polymer that is reinforced by fabric plies. Endless belt provides a conveyor belt of this type which has high static and dynamic strength at the connecting point, combined with great bending flexibility. This is achieved in that at least one fabric ply of each belt end, folded back on itself, wraps around a thickened area and extends between the thickened area and a stop, which forms an abutment with respect to the thickened area, in such a way that the fabric ply is jammed between the thickened area and the stop when tension acts on the belt in the reverse direction.
