This document provides an overview of ultrasonic motors. It discusses how ultrasonic motors work on the principle of inverse piezoelectric effect to directly convert electrical energy to mechanical energy. The motor consists of an actuator made of piezoelectric material, a stationary stator, a rotating rotor, and an outer casing. When voltage is applied to the actuator, it causes the stator to vibrate ultrasonically. Frictional contact between the vibrating stator and rotor causes the rotor to rotate, providing useful mechanical output. Ultrasonic motors offer advantages over traditional electromagnetic motors such as higher torque, smaller size, and greater potential for miniaturization.
Piezo valves offer several advantages over solenoid valves, including extremely low power consumption, proportional control, fast switching speeds, and long service life. They are well-suited for applications requiring precise flow or pressure control, such as in the semiconductor industry. Other promising applications of piezo valves include speed control of pneumatic cylinders and accurate metering for industrial adhesives. Overall, piezo valve technology is growing in importance due to its energy efficiency and suitability for proportional control systems.
Piezoelectricity is not a new concept but its application in recent instrumentation and daily life field is noticeable. i have prepared this report for enhancing and making the new technologies and applications about piezoelectronics known among readers. Don't forget to give feedback

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

DLAU und die Lizenzen nach dem CCB- und CCX-Modell sind für viele in der HCL-Community seit letztem Jahr ein heißes Thema. Als Notes- oder Domino-Kunde haben Sie vielleicht mit unerwartet hohen Benutzerzahlen und Lizenzgebühren zu kämpfen. Sie fragen sich vielleicht, wie diese neue Art der Lizenzierung funktioniert und welchen Nutzen sie Ihnen bringt. Vor allem wollen Sie sicherlich Ihr Budget einhalten und Kosten sparen, wo immer möglich. Das verstehen wir und wir möchten Ihnen dabei helfen!
Wir erklären Ihnen, wie Sie häufige Konfigurationsprobleme lösen können, die dazu führen können, dass mehr Benutzer gezählt werden als nötig, und wie Sie überflüssige oder ungenutzte Konten identifizieren und entfernen können, um Geld zu sparen. Es gibt auch einige Ansätze, die zu unnötigen Ausgaben führen können, z. B. wenn ein Personendokument anstelle eines Mail-Ins für geteilte Mailboxen verwendet wird. Wir zeigen Ihnen solche Fälle und deren Lösungen. Und natürlich erklären wir Ihnen das neue Lizenzmodell.
Nehmen Sie an diesem Webinar teil, bei dem HCL-Ambassador Marc Thomas und Gastredner Franz Walder Ihnen diese neue Welt näherbringen. Es vermittelt Ihnen die Tools und das Know-how, um den Überblick zu bewahren. Sie werden in der Lage sein, Ihre Kosten durch eine optimierte Domino-Konfiguration zu reduzieren und auch in Zukunft gering zu halten.
Diese Themen werden behandelt
- Reduzierung der Lizenzkosten durch Auffinden und Beheben von Fehlkonfigurationen und überflüssigen Konten
- Wie funktionieren CCB- und CCX-Lizenzen wirklich?
- Verstehen des DLAU-Tools und wie man es am besten nutzt
- Tipps für häufige Problembereiche, wie z. B. Team-Postfächer, Funktions-/Testbenutzer usw.
- Praxisbeispiele und Best Practices zum sofortigen Umsetzen

4. Electrical to mechanical energy conversion
Electromagnetic motor – traditional motors using magnetic field created
by electrical current flowing through the windings, exciting magnetic
field and producing mechanical force, converting into torque.
Piezomotor – other kind of motors using electrical field – voltage –
applied to the piezoactuators, converting mechanical vibration of the
actuator into force through the mechanical contact.

5. Principles of operation
Input power – AC voltage - is applied to the piezoceramic actuator of the
piezomotor at the resonant frequency thus exciting mechanical
vibrations of the actuator located mostly in the stator of motor.
Piezoelectric ultrasonic motors are driven by tangential stresses in the
interface between stator and rotor (direct contact) or pusher and rotor
(indirect contact).
These stresses are generated by elliptical motion of the material points
of the stator or rotor surfaces and depend on frictional processes in the
contact area.
The contact mechanics of the piezoelectric ultrasonic motors determines
the operational characteristics like rotational or linear speed and torque
or force or transmitted mechanical power and efficiency.
Lifetime and wear properties of piezoelectric motors are also determined
by contact mechanics and depend upon temperature

Application of the piezomotors are based on the following properties
1. simplicity;
2. small size and small step – widely used for cameras, optical systems scanning and
micromanipulators, minimal step may be in order of the fractions of angle second so
piezomotor is considered the ideal positioning device;
3. high torque – up to 50N*m (~35lb*ft) for currently produced motors – used for ball
valves for gas, oil and other liquids – currently produced in Ukraine, 500,000 cycles;
4. low rpm without the gearbox and wide speed range (from <1 to >5,000 rpm) make
possible direct drive;
5. nonmagnetic application – used for NMR systems in medical equipment;
6. low noise operation both mechanical and magnetic;
7. ability to work up to 250C and higher depending on the piezoceramic;
8. piezomotor combines motor and a break eliminating a need in separately controlled
breaks;
9. piezomotor output power does not depend upon the mass of the rotor thus providing
low delay time, which is important for close loop systems;
10. piezomotor is able to reconnect electrical circuitries in milliseconds making possible
to switch current while voltage is crossing zero;
12. reliability and lifetime depend upon a friction pair and currently is in the range of 500
to over 5,000 hours for room temperature, sample tested for 50h at 200C.
13. mechanical overload does not destroy piezomotor

Summary
1. Piezomotors may solve some problems with high current /
high voltage electromechanical switches operating downhole
especially in the strong magnetic fields – in NMR antennas.
2. Low rpm / high torque actuators may be used for calipers
3. Remote controlled ball valves operating without gearboxes
are tested, manufactured and used in Ukraine, they may
reliably regulate oil, gas, water or mud flows.
4. With over 40 years of experience with piezoceramic materials
Dr. Lavrinenko and his Laboratory of Piezoelectronics of
National Technical University “KPI” in Kiev, Ukraine may be
useful for energy service companies in wide range of
applications including piezomotors and other actuators and
piezotransformer based power supplies.
