Jakarta Web Services Metadata. Jakarta Web Services Metadata (JWS; formerly Web Services Metadata for Java platform and Java Web Services), as a part of Jakarta XML Web Services (JAX-WS), is a Java programming language specification (JSR-181) primarily used to standardize the development of web service interfaces for the Jakarta EE platform.

Using annotations from the JSR 181, you can annotate a Web service implementation class or a Web service interface. It enables developers to create portable Java Web Services from a simple plain old Java object (POJO) class by adding annotations, and also helps in generating a Web service with a wizard or by publishing the service on to a server.

Some of the annotations specified by this JSR are:
 @WebService
 @WebMethod
 @Oneway
 @WebParam
 @WebResult
 @HandlerChain
 @SOAPBinding

Put simply, JSR 181 is a specification to define standard and portable web services. It offers the following benefits:
 Provide a simplified model for developing web services
 Abstract the implementation details
 Achieve robustness, easy maintenance, and high interoperability

Version is 2.1 was released on December 15, 2009.

Jakarta Management. Jakarta Management (formerly J2EE Management) is a Java specification request (JSR-77) for standardization of Jakarta EE server management. Jakarta Management abstracts the manageable parts of the Jakarta EE architecture and defines an interface for accessing management information. This helps system administrators integrate Jakarta  EE servers into a system management environment and also helps application developers create their own management tools from scratch.

The goal of JSR 77 is to abstract the fundamental manageable aspects of the Jakarta EE architecture to provide a well defined model for implementing instrumentation and information access. In addition, this specification defines a standardized API for inter-operating with Jakarta EE components that participate in the monitoring and control of the platform’s resources.

The implementation of the JSR-77 for enterprise applications is done by the application server and for  it is done by the web container.

Jakarta Management was removed from Jakarta EE 9.

Overview
The Jakarta Management model is a specification of the attributes, operations and architecture of the managed objects required by compliant Jakarta EE platform implementations. The model is designed to be interoperable with a variety of industry standard management systems and protocols.

The Management EJB (MEJB) component provides interoperable remote access of the model to Jakarta EE application components. All compliant implementations must support the MEJB component. This specification also provides standard mappings of the model to the CIM/WBEM Common Information Model (CIM) and the SNMP Management Information Base (MIB). Further, implementation support for SNMP and CIM/WBEM is optional.

Latest version of this JSR is 1.1 released on 8 May 2006.

IPhone accessories. The iPhone has a wide variety of accessories made by Apple available for it.

EarPods

Apple EarPods (introduced on September 12, 2012) first shipped with the iPhone 5 and feature a remote control and microphone. They also ship with the fifth-generation iPod touch (without mic) and the seventh-generation iPod nano (without mic). They're also sold independently. The Apple EarPods are assembled in Vietnam.

All but the basic earbuds have control capsules allowing users to adjust volume and control music and video playback, located on the cable of the right earpiece; those "with Remote and Mic" also include a microphone for phone calls and voice control of certain devices. Users can adjust volume, control music and video playback (play/pause and next/previous,) and record voice memos on supported iPod and iPhone models and Mac computers. There have been many reports of moisture problems with the remote/mic earbuds. The original iPhone and iPhone 3G came with the iPhone Stereo Headset, a push-button and microphone on the right side of the headphones (there is no volume control, and only limited control of calls).

Dock
A series of docks released for the iPhone 5, 5s, and 5c, were announced and released on September 10, 2013. The docks have an identical design, with an audio-out and Lightning-in port on the back, and a Lightning connector on the top. One dock was released solely for the iPhone 5 and 5s, with another dock optimized for the iPhone 5c. The dock is not compatible with iPhones in their cases.

Case
For the physical care of the cell phone it is advisable to use cases that cover the entire back of the cell phone. Currently there are many distributors that offer different alternatives in models, materials, colors and custom designs.

Zeppelin-Lindau D.I. The Zeppelin D.I, or Zeppelin-Lindau D.I or Zeppelin D.I (Do), as named in German documents, also sometimes referred to postwar as the Dornier D.I or Dornier-Zeppelin D.I, for the designer, was a single-seat all-metal stressed skin monocoque cantilever-wing biplane fighter, developed by Claude Dornier while working for Luftschiffbau Zeppelin at their Lindau facility. It was too late to see operational service with the German Air Force (Luftstreitkräfte) during World War I.

Development and design

The Dornier D.I was one of several designs by Claude Dornier to have an all-metal stressed skin monocoque structure, and it was the first fighter to feature such construction and although production was halted prior to the completion of any production versions, it was also the first aircraft with these features to go into production. To reduce the hazards of inflight fires it also had an external fuel tank which may have been jettisonable, according to some sources and thick-section cantilever wings for improved aerodynamics. The Dornier Do H Falke monoplane was developed from it with an enlarged upper wing compensating for the removal of the lower wing.

Operational history
Seven prototypes were built but this design was never used operationally in World War I. Luftstreitkräfte (German Air Force) pilots evaluated the type in May and June 1918 and again in October. German ace Wilhelm Reinhard was killed on 3 July 1918 after a structural failure when it was supposed to have been grounded for structural improvements. There were reports of heavy aileron controls and poor climb rates at altitude. After being fitted with a more powerful BMW IIIa inline-six liquid-cooled engine that reduced the time needed to rate to reach  from 25 minutes to 13 minutes, an order was placed for 50 aircraft either in October or November. These were roughly 50 percent complete when production was halted following the armistice in early 1919. One example went to the US Navy and another to the US Army Air Service, both purchased in 1921 and delivered in 1922, for evaluation of the novel construction methods used.

Tube-based nanostructure. Tube-based nanostructures are nanolattices made of connected tubes and exhibit nanoscale organization above the molecular level.

Lattices
Lattices are structures formed of arrays of uniformly sized cells. Ceramic lattice nanostructures have been formed using hollow tubes of titanium nitride (TiN). Using vertex-connected, tessellated octahedra with 7-nm hollow struts with elliptical cross-sections and wall thickness of 75-nm produced approximately cubic cells 100-nm on a side at a scale of up to 1 cubic millimeter. The material's relative density was of the order of 0.013 (similar to aerogels).

Compression experiments with multiple deformation cycles revealed tensile strengths of 1.75 GPa without failure.

The material was constructed from a digital design with direct laser writing onto a photopolymer using 2-photon lithography followed by conformal deposition of TiN using atomic layer deposition and a final etching to remove the polymer.

An earlier metallic tube lattice produced hollow tube nickel microlattices with a density of .9 milligram per cubic centimeter and complete recovery after compression exceeding 50% strain with energy absorption similar to elastomers. Young's modulus E scales with density as E ~ ρ2, in contrast to the E ~ ρ3 scaling observed for ultralight aerogels and carbon nanotube nanofoams with stochastic architecture. Hardness of 6 GPa and a modulus of 210 GPa were measured by nanoindentation and hollow tube compression experiments, respectively. These materials are fabricated by starting with a template formed by self-propagating photopolymer waveguide prototyping, coating the template by electroless nickel plating, and subsequently etching away the template.

Organic nanostructures

Nanostructured hollow multilayered tubes can be created by combining layer-by-layer (LbL) and template leaching.
Such materials are of particular interest for tissue engineering since they allow the precise control of physical and biochemical cues of implantable devices. The tubes are based on polyelectrolyte multilayer films. The final tubular structures can be characterized by differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), microscopy, swelling and mechanical tests, including dynamic mechanical analysis (DMA) in physiological simulated conditions. More robust films could be produced via chemical cross-linking with genipin. Water uptake decreases from about 390% to 110% after cross-linking. The cross-linked tubes are more suitable structures for cell adhesion and spreading. Potential applications include tissue engineering.

Specific mechanical energy. Specific mechanical energy is the mechanical energy of an object per unit of mass. Similar to mechanical energy, the specific mechanical energy of an object in an isolated system subject only to conservative forces will remain constant.

It is defined as:

= k+p

where

 k is the specific kinetic energy
 p it the specific potential energy

Astrodynamics 
In the gravitational two-body problem, the specific mechanical energy of one body  is given as:

where

  is the orbital speed of the body; relative to center of mass.
  is the orbital distance between the body and center of mass;
  is the standard gravitational parameter of the bodies;
  is the specific relative angular momentum of the same body referenced to the center of mass. In other context h is used in the sense of a total for two bodies expressed as relative angular momentum of the system divided by the reduced mass, giving the same result for a central force problem;
  is the orbital eccentricity;
  is the semi-major axis of the body orbit.

The relations are used.

 ) 

where

  is the conic section semi-latus rectum.
  is distance at periastron of the body from the center of mass.

where
 is the standard gravitational parameter, G(m1+m2), often expressed as GM when one body is much larger than the other.
 is the distance between the orbiting body and center of mass.
 is the length of the semi-major axis.

Orbital Mechanics 
When calculating the specific mechanical energy of a satellite in orbit around a celestial body, the mass of the satellite is assumed to be negligible:

where  is the mass of the celestial body. When GM is used the center of mass is at the center of M.
When bodies cannot accurately be described as point masses in the equations, other math is required and a difference may be required between center of mass and center of gravity.
In star systems of more than one planet, a planet orbit differs slightly from ideal with corrections applied for the other planets.
