A Single Stage Virtual Synchronous Machine
2019 IEEE International Conference on Industrial Technology (ICIT), 2019Virtual Synchronous Machines (VSM) are proposed to support a power grid with high penetration of inverter-based distribution generation (DG) units. When the number of inverters connected to a grid increases, grid lacks the inertia that conventionally is introduced by the synchronous machine (SM). Therefore, VSMs are proposed to virtually introduce such

In this chapter, the test problem is introduced for the case of a standard single-stage design, meaning that no interim analysis is performed. The underlying parameters and distributional assumptions, the test problems, and the test statistics will be separately formulated for (composite) binary endpoints and for (composite) time-to-(first-)event ...

Aircraft Engineering and Aerospace Technology, 1940
IN many types of engine the supercharger is built on to the accessory‐drive end, that is the rear of the engine, so that the supercharger shaft lies co‐axially or parallel with the crankshaft. This has the great advantage of permitting the use of simple spur gearing, but suffers from the disadvantage that in passing through both intake and delivery ...

Analysis of Concepts for Single Stage to Orbit
Journal of Spacecraft and Rockets, 1996Introduction T HE Space Shuttle was designed in the 1970s and is still the most efficient manned Earth-to-orbit vehicle available. However, operation of the Space Shuttle costs much more than planned. For future space missions, a new transportation system is desired to improve the operability and costs. The primary purpose of this study was to consider

SINGLE STAGE EXCISION OF PREAURICULAR SINUS
Australian and New Zealand Journal of Surgery, 1995A total of 44 patients with preauricular sinus underwent one‐stage surgical treatment. There were 32 unilateral and 12 bilateral cases giving a total of 56 sinuses. Of these 16 were infected at the time of presentation. Based on the observation that preauricular sinus represents the duct of a preauricular gland which is closely adherent to the ...

The Single Stages of Reconstruction
1991Relations within the man—environment—system change with time after a disaster. Hazard research proposes that this time can be divided into four typical stages. Our research aimed to test this theory.

The Nasolabial Flap as a Single-Stage Procedure
Archives of Dermatology, 1990The nasolabial flap is a useful reconstructive technique for the repair of defects on the nose. An improved technique used in 32 patients is presented, which allows use of this procedure as a single-stage rather than the more commonly seen two-stage procedure.
