Type-Safety
•Java does not have strongly typed base types
(like e.g. Ada or Smalltalk).
• This could change around Java 10 or 11
(based on Oracle Road Map and statements)
•For performance reasons most developer prefer
primitive types over objects in their interface.
•Primitive type arguments can more easily lead to
name clashes (methods with the same signature)
or other problems (“Auto-Boxing”,…)

What do these disasters have in common?
•Patriot Missile
The cause was an inaccurate calculation of the time since boot due to a
computer arithmetic error.
•Ariane 5 Explosion
Floating point number which a value was converted from had a value
greater than what would be represented by a 16 bit signed integer.
• Gimli Glider (near disaster)
Fuel loading was miscalculated through misunderstanding of the recently
adopted Metric System, replacing the Imperial System in Canada
11 © 2007-2012 Creative Arts & Technologies
• Mars Orbiter
Preliminary findings indicate that one team used US/English units
(e.g. inches, feet and pounds) while the other used metric units for
a key spacecraft operation.
• NASA lost a $125 million Mars orbiter because a Lockheed Martin engineering team
used English units of measurement while the agency's team used the more
conventional metric system for a key spacecraft operation
• A credible source disclosed, there was a manual step with an outsourced person to
convert these calculations between the different teams, and NASA budget cuts caused
them to fire him and have the wrong, unpatched data transmitted!!!
• This also underlines the added risk when 3rd party contractors are involved or projects
are developed Offshore

23rd March 1983. Ronald Reagan
announces SDI (or “Star Wars”): ground-
based and space-based systems to
protect the US from attack by strategic
nuclear ballistic missiles.

1985: Why it happened?
Unit Tests wouldn„t find these…
• All previous examples illustrate three categories of
errors difficult to find through Unit Testing:
• Interface Errors (e.g. millisecond/second, radian/degree, meters/feet).
• Arithmetic Errors (e.g. overflow).
• Conversion Errors.
Despite their name
17 © 2007-2012 Creative Arts & Technologies Images © Copyright, American Shakespeare Center
Causes of Conversion Errors
• Ambiguity on the unit
• Gallon Dry / Gallon Liquid - Gallon US / Gallon UK
• Day Sidereal / Day Calendar
• Foot in various regions, at least historically, see:
http://en.wikipedia.org/wiki/German_obsolete_units_of_measurement#Fu.C3.
9F_.28foot.29
• Degree Celsius / Degree Fahrenheit
• Did you know that Gabriel Fahrenheit was born in Gdansk (Danzig) in northern
Poland?
• ...
• Wrong conversion factors:
static final double PIXEL_TO_INCH = 1 / 72;
double pixels = inches * PIXEL_TO_INCH

Groups a state name, value and timestamp.
• Some usage, especially in Automotive
► no further development by OSGi
OSGi
20 © 2007-2012 Creative Arts & Technologies
• Namespace: javax.microediton.sensor*
• Focusing on Sensors, but it got a minimalistic Unit API “in
the closet”
• Unit
Essentially an SI singleton holding relevant unit constants, too.
JavaDoc: http://pandora.la/java/javadocs/sensor/javax/microedition/sensor/Unit.html
• ChannelInfo
Holding name, accuracy, data type,measurement ranges, scale and unit
• MeasurementRange
Range of possible values from minimum to maximum
► Dead Meat (few actual handsets and no vendors
except Nokia still use it, nor does Java ME Embedded)
JSR-256
21 © 2007-2013 Creative Arts & Technologies
Mobile Sensor API
• Namespace: javax.measure.*
• Only one interface and one abstract class
• public interface Measurable<Q extends Quantity>
• public abstract class Measure<V, Q extends Quantity>
• Three sub-packages
• quantity (holds dimensions mass, length)
• unit (holds the SI and NonSI units)
• converter (holds unit converters)
JSR-275
22 © 2007-2012 Creative Arts & Technologies
Units Specification
• Namespace: org.unitsofmeasurement.*
• Only interfaces (and exception classes)
• public interface Quantity<Q extends Quantity<Q>>
• public interface Unit<Q extends Quantity<Q>>
• Three sub-packages
• quantity (holds dimensions mass, length,...)
• unit (holds units)
• service (holds services)

Units of Measurement API
Eclipse UOMo
One Small Step…
One Unit Framework to Measure them All
• Namespace: org.eclipse.uomo.*
• Two main areas
• Static Type Safe Units of Measure Support
• Based on Units of Measurement API
• On top of ICU4J, the Globalization standard at Eclipse and
others (Android, GWT, Google Financial, etc.)
• Prime UCUM Implementation
• Successor to Eclipse OHF UCUM Bundle
Eclipse UOMo
25 © 2007-2012 Creative Arts & Technologies
Unified Code for Units of Measure
The Unified Code for Units of Measure is inspired by
and heavily based on
• ISO 2955-1983
• ANSI X3.50-1986
• HL7's extensions called ISO+
UOMo UCUM
26 © 2007-2012 Creative Arts & Technologies
JSR 354 Implementation
“Sisu” equivalent for 354 if you want
• ICU4J based implementation
of types like
• CurrencyUnit
• MonetaryAmount
• CurrencyConverter
• ExchangeRate
• …
• Bridge to Unit-API where possible for cross-quantity
arithmetic (e.g. “$ per gram CO² per mile”)

“A coordinated observation infrastructure composed of a distributed collection of
resources that can collectively behave as a single, autonomous, task-able,
dynamically adaptive and reconfigurable observing system that provides raw and
processed data, along with associated meta-data, via a set of standards-based
service-oriented interfaces.” (Glenn, 2007)

SensorML
• Sensor modeling language is the cornerstone of
all SW services
• It provides comprehensive description of sensor
parameters and capabilities
• It can be used for describing different kind of
sensors:
– Stationary or dynamic
– Remote or in-situ
– Physical measurements or simulations

A Publish Subscribe messaging protocol allowing a message to be published once and multiple consumers
(applications / devices) to receive the message providing decoupling between the producer and consumer(s)
A producer sends (publishes) a message (publication) on a topic (subject)
A consumer subscribes (makes a subscription) for messages on a topic (subject)
A message server / broker matches publications to subscriptions
• If no matches the message is discarded
• If one or more matches the message is delivered to each matching subscriber/consumer
MQTT - Publish Subscribe Messaging
44 © 2007-2013 Creative Arts & Technologies, Eclipse Foundation, Inc. Made available under the Eclipse Public License 1.0
■ Push delivery of messages / data / events
– MQTT – low latency push delivery of messages from client to server and server
to client
• Helps bring an event oriented architecture to the web
– HTTP – push from client to server but poll from server to client
• Efficient use of network
– For an M2M project the number of bytes with MQTT was 137130 bytes per device per
month with HTTP the number of bytes was 801000 bytes per device per month
• Reliable delivery over fragile network
– MQTT will deliver message to QOS even across connection breaks
• Decoupling and publish subscribe – one to many delivery

Open NFC interfaces can be classified at different levels, from very
high-level interfaces that greatly simplify the usual tasks of NFC
applications, to very low-level interfaces that allow fine tuning of NFC
hardware parameters for example.
High Level Interfaces:
• NDEF Messages
• Bluetooth and Wi-Fi pairing
• Read / Write to any tag
• P2P
• Virtual Tags

  • 10. Type-Safety •Java does not have strongly typed base types (like e.g. Ada or Smalltalk). • This could change around Java 10 or 11 (based on Oracle Road Map and statements) •For performance reasons most developer prefer primitive types over objects in their interface. •Primitive type arguments can more easily lead to name clashes (methods with the same signature) or other problems (“Auto-Boxing”,…) 10 © 2007-2013 Creative Arts & Technologies
  • 11. What do these disasters have in common? •Patriot Missile The cause was an inaccurate calculation of the time since boot due to a computer arithmetic error. •Ariane 5 Explosion Floating point number which a value was converted from had a value greater than what would be represented by a 16 bit signed integer. • Gimli Glider (near disaster) Fuel loading was miscalculated through misunderstanding of the recently adopted Metric System, replacing the Imperial System in Canada 11 © 2007-2012 Creative Arts & Technologies
  • 12. • Mars Orbiter Preliminary findings indicate that one team used US/English units (e.g. inches, feet and pounds) while the other used metric units for a key spacecraft operation. • NASA lost a $125 million Mars orbiter because a Lockheed Martin engineering team used English units of measurement while the agency's team used the more conventional metric system for a key spacecraft operation • A credible source disclosed, there was a manual step with an outsourced person to convert these calculations between the different teams, and NASA budget cuts caused them to fire him and have the wrong, unpatched data transmitted!!! • This also underlines the added risk when 3rd party contractors are involved or projects are developed Offshore What do these disasters have in common? 12 © 2007-2012 Creative Arts & Technologies

Unit Tests wouldn„t find these… • All previous examples illustrate three categories of errors difficult to find through Unit Testing: • Interface Errors (e.g. millisecond/second, radian/degree, meters/feet). • Arithmetic Errors (e.g. overflow). • Conversion Errors. Despite their name 17 © 2007-2012 Creative Arts & Technologies Images © Copyright, American Shakespeare Center
  • 18. Causes of Conversion Errors • Ambiguity on the unit • Gallon Dry / Gallon Liquid - Gallon US / Gallon UK • Day Sidereal / Day Calendar • Foot in various regions, at least historically, see: http://en.wikipedia.org/wiki/German_obsolete_units_of_measurement#Fu.C3. 9F_.28foot.29 • Degree Celsius / Degree Fahrenheit • Did you know that Gabriel Fahrenheit was born in Gdansk (Danzig) in northern Poland? • ... • Wrong conversion factors: static final double PIXEL_TO_INCH = 1 / 72; double pixels = inches * PIXEL_TO_INCH 18 © 2007-2013 Creative Arts & Technologies
