J/mol
The joule per mole (symbol: J· mol⁻¹) is an SI derived unit of energy per amount of material. Energy is measured in joules, and the amount of material is measured in moles. Physical quantities measured in J· mol⁻¹) usually describe quantities of energy transferred during phase transformations or chemical reactions. Division by the number of moles facilitates comparison between processes involving different quantities of material and between similar processes involving different types of materials. The meaning of such a quantity is always context-dependent and, particularly for chemical reactions, is dependent on the (possibly arbitrary) definition of a 'mole' for a particular process.

An electron volt (eV) is the energy that an electron gains when it travels through a potential of one volt. You can imagine that the electron starts at the negative plate of a parallel plate capacitor and accelerates to the positive plate, which is at one volt higher potential. Numerically 1 eV approximates 1.6x10⁻¹⁹ joules, where 1 joule is 6.2x10¹⁸ eV. For example, it would take 6.2x10²⁰ eV/sec to light a 100 watt light bulb.

A matter object throughout which all physical properties of a material are essentially uniform.
In the physical sciences, a phase is a region of space (a thermodynamic system), throughout which all physical properties of a material are essentially uniform. Examples of physical properties include density, index of refraction, magnetization and chemical composition. A simple description is that a phase is a region of material that is chemically uniform, physically distinct, and (often) mechanically separable. In a system consisting of ice and water in a glass jar, the ice cubes are one phase, the water is a second phase, and the humid air is a third phase over the ice and water. The glass of the jar is another separate phase.
The term phase is sometimes used as a synonym for state of matter, but there can be several immiscible phases of the same state of matter. Also, the term phase is sometimes used to refer to a set of equilibrium states demarcated in terms of state variables such as pressure and temperature by a phase boundary on a phase diagram. Because phase boundaries relate to changes in the organization of matter, such as a change from liquid to solid or a more subtle change from one crystal structure to another, this latter usage is similar to the use of "phase" as a synonym for state of matter. However, the state of matter and phase diagram usages are not commensurate with the formal definition given above and the intended meaning must be determined in part from the context in which the term is used.

A quantity value is not necessarily a property, since it is possible to write "10 kg", without assigning this quantity to a specific object.
Following the International Vocabulary of Metrology (VIM), EMMO distinguishes between a quantity (a property) and the quantity value (a numerical and a reference).
So, for the EMMO the symbol "kg" is not a physical quantity but simply a 'Symbolic' object categorized as a 'MeasurementUnit'.
While the string "1 kg" is a 'QuantityValue'.

Direct parthood is the non transitive version of parthood enabling the establishment of hierarchy of granularities, starting with an entity and providing several tesselation levels according to specific criteria.
The criteria are implemented in specialised versions of the direct parthood relation (e.g., metrological direct part, XML format direct part).
The direct parts (tiles) and the tessellated entity (tessellation) are causally self connected (i.e., items), coherently with the concept behind the definition of the reductionistic perspective.
The relation grouping all direct parthood relations used in the reductionistic perspective.
This relation is not antitransitive, to enable partitioning of a causal structure with more than one tiling scheme (e.g. time and space partitioning).
This relation is a simple collector of all relations inverse functional direct parthoods that can be defined in specialised theories using reductionism.

The interpretation of the term "matter" is not univocal. Several concepts are labelled with this term, depending on the field of science. The concept mass is sometimes related to the term "matter", even if the former refers to a physical quantity (precisely defined by modern physics) while the latter is a type that qualifies a physical entity.
It is possible to identify more than one concept that can be reasonably labelled with the term "matter". For example, it is possible to label as matter only the entities that are made up of atoms. Or more generally, we can be more fine-grained and call "matter" the entities that are made up of protons, neutrons or electrons, so that we can call matter also a neutron radiation or a cathode ray.
A more fundamental approach, that we embrace for the EMMO, considers matter as entities that are made of fermions (i.e. quarks and leptons). This would exclude particles like the W and Z bosons that possess some mass, but are not fermions.
Antimatter is a subclass of matter.
A physical object made of fermionic quantum parts.
A matter entity exclude the presence of (real) fundamental bosons parts. However, it implies the presence of virtual bosons that are responsible of the interactions between the (real) fundamental fermions.
Matter includes ordinary- and anti-matter. It is possible to have entities that are made of particle and anti-particles (e.g. mesons made of a quark and an anti-quark pair) so that it is possible to have entities that are somewhat heterogeneous with regards to this distinction.

A 'Sign' can have temporal-direct-parts which are 'Sign' themselves.
A 'Sign' usually havs 'sign' spatial direct parts only up to a certain elementary semiotic level, in which the part is only a 'Physical' and no more a 'Sign' (i.e. it stands for nothing). This elementary semiotic level is peculiar to each particular system of signs (e.g. text, painting).
Just like an 'Elementary' in the 'Physical' branch, each 'Sign' branch should have an a-tomistic mereological part.
According to Peirce, 'Sign' includes three subcategories:
- symbols: that stand for an object through convention
- indeces: that stand for an object due to causal continguity
- icons: that stand for an object due to similitudes e.g. in shape or composition
Sign
An 'Physical' that is used as sign ("semeion" in greek) that stands for another 'Physical' through an semiotic process.
A novel is made of chapters, paragraphs, sentences, words and characters (in a direct parthood mereological hierarchy).
Each of them are 'sign'-s.
A character can be the a-tomistic 'sign' for the class of texts.
The horizontal segment in the character "A" is direct part of "A" but it is not a 'sign' itself.
For plain text we can propose the ASCII symbols, for math the fundamental math symbols.

It is natural to define entities made or more than one smaller parts according to some unity criteria. One of the most general one applicable to causal systems is to ask that all the quantum parts of the system are bonded to the rest.
In other words, causal convexity excludes all quantums that leave the system (no more interacting), or that are not yet part of it (not yet interacting).
So, a photon leaving a body is not part of the body as convex system, while a photon the is carrier of electromagnetic interaction between two molecular parts of the body, is part of the convex body.

This relation identifies parts of a 4D object that do not fully cover the lifetime extent of the whole (spatial) nor the full spatial extent (temporal).
This relation is a filler, to categorise the parts of an entity that are not covered by the other parthood relations.
A proper part is then the disjoint union of: spatial part, temporal part and spatio temporal part relations.

Radioactive decays per second.
SI unit for radioactive activity.
The SI derived unit of activity, usually meaning radioactivity. "Radioactivity" is caused when atoms disintegrate, ejecting energetic particles. One becquerel is the radiation caused by one disintegration per second; this is equivalent to about 27.0270 picocuries (pCi). The unit is named for a French physicist, Antoine-Henri Becquerel (1852-1908), the discoverer of radioactivity. Note: both the becquerel and the hertz are basically defined as one event per second, yet they measure different things. The hertz is used to measure the rates of events that happen periodically in a fixed and definite cycle. The becquerel is used to measure the rates of events that happen sporadically and unpredictably, not in a definite cycle.

Relates a quantity to its metrological reference through a semiotic process.
In EMMO version 1.0.0-beta7, physical quantities used the hasMetrologicalReference object property to relate them to their units via physical dimensionality. This was simplified in 1.0.0-alpha3 in order to make reasoning faster.
The restriction (e.g. for the physical quantity Length)
Length hasMetrologicalReference only (hasPhysicsDimension only LengthDimension)
was in 1.0.0-alpha3 changed to
Length hasPhysicsDimension some LengthDimension
Likewise were the universal restrictions on the corresponding unit changed to excistential. E.g.
Metre hasPhysicsDimension only LengthDimension
was changed to
Metre hasPhysicsDimension some LengthDimension
The label of this class was also changed from PhysicsDimension to PhysicalDimension.
hasMetrologicalReference
We say that an entity causes another if there is a quantum part of the first that is in causal relation with a quantum parts of the second.
An entity cannot cause itself (causal loops are forbidden) or a part of itself. For this reasons causality between entities excludes reflexivity and prevents them to overlap.
The relation between an individuals x and y, that holds if and only if:
a) y having a part that is causing an effect on a part of x
b) y and x non-overlapping
:isCauseOf owl:propertyDisjointWith :overlaps
Each pair of causally connected entities is either in isDirectCauseOf or isIndirectCauseOf relation. The two are mutually exclusive.
It applies to both quantums and macro-entities (entities made of more than one quantum). It is admissible for two entities to be one the cause of the other, excepts when they are both quantums.
The OWL 2 DL version of the EMMO introduces this object property as primitive causal relation. It refers to the macro causality relation mC(x,y), defined in the EMMO FOL version.
While the EMMO FOL introduces the quantum causality relation C(x,y) as primitive, the OWL 2 DL version substantially simplifies the theory, neglecting these lower level relations that are well above DL expressivity.

A collection is the concept that complements the item concept, being an entity that possesses at least one part non directly causally connected with the rest.
A collection can be partitioned in maximally connected items called members. The members are self-connected entities and there is no direct causality relation between them.
The combination of collection and item concepts is the EMMO mereocausality alternative to set theory. However, two items can be members only if they are non direct causally connected, giving some constraints to a collection definition. For example, two entities which are directly connected cannot be two distinct members, while their interiors (i.e. the entities obtained by removing the layer of parts that provides the causal contact between them) can be.

A class devoted to categorize causal objects by specifying their granularity levels.
A granularity level is specified by a tiling decomposition of the whole y. A tiling is identified as a set of items {x1, x2, ... xn} called tiles that:
- are proper parts of y
- covers the entire whole (y = x1 +x2 + ... + xn)
- do not overlap
- are part of one, and one only, whole (inverse functional)
Direct parthood is the antitransitive parthood relation used to build the class hierarchy (and the granularity hierarchy) for this perspective.

Here is assumed that the concept of 'object' is always relative to a 'semiotic' process. An 'object' does not exists per se, but it's always part of an interpretation.
The EMMO relies on strong reductionism, i.e. everything real is a formless collection of elementary particles: we give a meaning to real world entities only by giving them boundaries and defining them using 'sign'-s.
In this way the 'sign'-ed entity becomes an 'object', and the 'object' is the basic entity needed in order to apply a logical formalism to the real world entities (i.e. we can speak of it through its sign, and use logics on it through its sign).
Object
SemioticObject
The object, in Peirce semiotics, as participant to a semiotic process.
1e-24
An entity that is categorized according to its relation with a whole through a parthood relation and that contributes to it according to an holistic criterion, where the type of the whole is not the type of the part.
In this class the concept of role and part are superimposed (the term part is also used to define the role played by an actor).
Here entities are categorized according to their relation with the whole, i.e. how they contribute to make a specific whole, and not what they are as separate entities.
This class is expected to host the definition of world objects as they appear in its relation with the surrounding whole (being a part implies being surrounded by something bigger to which it contributes).

A reference can be a measurement unit, a measurement procedure, a reference material, or a combination of such (VIM3 1.1 NOTE 2).
A symbolic is recognized as reference unit also if it is not part of a quantity (e.g. as in the sentence "the Bq is the reference unit of Becquerel").
For this reason we can't declare the axiom:
MetrologicalReference SubClassOf: inverse(hasMetrologicalReference) some Quantity
because there exist reference units without being part of a quantity.
This is peculiar to EMMO, where quantities as syntatic entities (explicit quantities) are distinct with quantities as semantic entities (properties).

Measured or simulated 'physical propertiy'-s are always defined by a physical law, connected to a physical entity through a model perspective and measurement is done according to the same model.
Systems of units suggests that this is the correct approach, since except for the fundamental units (length, time, charge) every other unit is derived by mathematical relations between these fundamental units, implying a physical laws or definitions.
Measurement units of quantities of the same quantity dimension may be designated by the same name and symbol even when the quantities are not of the same kind.
For example, joule per kelvin and J/K are respectively the name and symbol of both a measurement unit of heat capacity and a measurement unit of entropy, which are generally not considered to be quantities of the same kind.
However, in some cases special measurement unit names are restricted to be used with quantities of specific kind only.
For example, the measurement unit ‘second to the power minus one’ (1/s) is called hertz (Hz) when used for frequencies and becquerel (Bq) when used for activities of radionuclides.
As another example, the joule (J) is used as a unit of energy, but never as a unit of moment of force, i.e. the newton metre (N · m).
— quantities of the same kind have the same quantity dimension,
— quantities of different quantity dimensions are always of different kinds, and
— quantities having the same quantity dimension are not necessarily of the same kind.

A spatial contact between two entities occurs when the two entities are in an interaction relation whose causal structure is a representation of the fundamental interactions between elementary particles (Feynman diagrams).
It means that if two entities are in contact, then there is at least a couple of elementary particles, one part of the first and one part of the second, interacting according to one of the fundamental interactions through virtual particles. This kind of connection is space-like (i.e. interconnecting force carrier particle is offshelf).
Contacts between two entities exclude the possibility of other causal relations that are not included in a fundamental space-like interaction.
An interaction that is the sum of direct causality relations between two entities that are interpretable as fundamental physical interactions.
Spatial contact is symmetric and irreflexive.

The EMMO conceptualises the world using the primitive concepts of causality and parthood. Parthood is about the composition of world entities starting from other more fundamental entities. Causality is about the interactions between world entities.
The quantum is the smallest indivisible part of any world entity. Quantum individuals are the fundamental causal constituents of the universe, since it is implied that causality originates from quantum-to-quantum interactions. Quantums are no-dimensional, and their aggregation makes spacetime emerge from their causal structure. Causality between macro entities (i.e. entities made of more than one quantum) is explained as the sum of the causality relations between their quantum constituents.
The fundamental distinction between world entities is direct causality self-connectedness: a world entity can be self-connected xor not self-connected depending on the causality network of its fundamental components.
Void regions do not exist in the EMMO, or in other words there is no spacetime without entities, since space and time are measured quantities following a causality relation between entities (spacetime emerges as relational property not as a self-standing entity).
Entities are not placed in space or time: space and time are always relative between entities and are measured. In other words, space and time relations originates from causality interactions.
The disjoint union of the Item and Collection classes.
The class of all the OWL individuals declared by EMMO as standing for world entities.
EMMO entities dimensionality is related to their mereocausal structures. From the no-dimensional quantum entity, we introduce time dimension with the elementary concept, and the spacetime with the causal system concept.
The EMMO conceptualisation does not allow the existence of space without a temporal dimension, the latter coming from a causal relation between entities.
For this reason, the EMMO entities that are not quantum or elementaries, may be considered to be always spatiotemporal. The EMMO poses no constraints to the number of spatial dimensions for a causal system (except being higher than one).

au
An astronomical unit (abbreviated as AU, au, a.u., or ua) is a unit of length equal to 149,597,870,700 metres (92,955,807.273 mi) or approximately the mean Earth Sun distance. The symbol ua is recommended by the International Bureau of Weights and Measures, and the international standard ISO 80000, while au is recommended by the International Astronomical Union, and is more common in Anglosphere countries. In general, the International System of Units only uses capital letters for the symbols of units which are named after individual scientists, while au or a.u. can also mean atomic unit or even arbitrary unit. However, the use of AU to refer to the astronomical unit is widespread. The astronomical constant whose value is one astronomical unit is referred to as unit distance and is given the symbol A.

SI unit for magnetic flux.
The SI unit of magnetic flux. "Flux" is the rate (per unit of time) at which something crosses a surface perpendicular to the flow. The weber is a large unit, equal to 10⁸ maxwells, and practical fluxes are usually fractions of one weber. The weber is the magnetic flux which, linking a circuit of one turn, would produce in it an electromotive force of 1 volt if it were reduced to zero at a uniform rate in 1 second. In SI base units, the dimensions of the weber are (kg·m²)/(s²·A). The weber is commonly expressed in terms of other derived units as the Tesla-square meter (T·m²), volt-seconds (V·s), or joules per ampere (J/A).

SI unit for equivalent doseof ionizing radiation. Sievert is derived from absorbed dose, but takes into account the biological effectiveness of the radiation, which is dependent on the radiation type and energy.
Although the sievert has the same dimensions as the gray (i.e. joules per kilogram), it measures a different quantity. To avoid any risk of confusion between the absorbed dose and the equivalent dose, the corresponding special units, namely the gray instead of the joule per kilogram for absorbed dose and the sievert instead of the joule per kilogram for the dose equivalent, should be used.

http://dbpedia.org/resource/Farad
The SI unit of electric capacitance. Very early in the study of electricity scientists discovered that a pair of conductors separated by an insulator can store a much larger charge than an isolated conductor can store. The better the insulator, the larger the charge that the conductors can hold. This property of a circuit is called capacitance, and it is measured in farads. One farad is defined as the ability to store one coulomb of charge per volt of potential difference between the two conductors. This is a natural definition, but the unit it defines is very large. In practical circuits, capacitance is often measured in microfarads, nanofarads, or sometimes even in picofarads (10⁻¹² farad, or trillionths of a farad). The unit is named for the British physicist Michael Faraday (1791-1867), who was known for his work in electricity and electrochemistry.

SI unit for electric charge.
The SI unit of electric charge. One coulomb is the amount of charge accumulated in one second by a current of one ampere. Electricity is actually a flow of charged particles, such as electrons, protons, or ions. The charge on one of these particles is a whole-number multiple of the charge e on a single electron, and one coulomb represents a charge of approximately 6.241 506 x 1018 e. The coulomb is named for a French physicist, Charles-Augustin de Coulomb (1736-1806), who was the first to measure accurately the forces exerted between electric charges.

Computation
From Latin con- + putō (“I reckon”).
A conventional referring to an object according to a specific code that reflects the results of a specific interaction mechanism and is shared between other interpreters.
A coded is always a partial representation of an object since it reflects the object capability to be part of a specific determination.
A coded is a sort of name or label that we put upon objects that interact with an determiner in the same specific way.
For example, "hot" objects are objects that interact with an observer through a perception mechanism aimed to perceive an heat source. The code is made of terms such as "hot", "warm", "cold", that commonly refer to the perception of heat.
Let's define the class Colour as the subclass of the coded signs that involve photon emission and electromagnetic radiation sensible observers.
An individual C of this class Colour can be defined be declaring the process individual (e.g. daylight illumination) and the observer (e.g. my eyes)
Stating that an entity E hasCoded C, we mean that it can be observed by such setup of process + observer (i.e. observed by my eyes under daylight).
This definition can be specialised for human eye perception, so that the observer can be a generic human, or to camera perception so that the observer can be a device.
This can be used in material characterization, to define exactly the type of measurement done, including the instrument type.
Coded
A conventional that stands for an object according to a code of interpretation to which the interpreter refers.

Cel
http://dbpedia.org/resource/Celsius
Measurement unit for Celsius temperature. This unit can only be used for expressing temperature differences.
Celsius, also known as centigrade, is a scale and unit of measurement for temperature. It can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval, a difference between two temperatures or an uncertainty. This definition fixes the magnitude of both the degree Celsius and the kelvin as precisely 1 part in 273.16 (approximately 0.00366) of the difference between absolute zero and the triple point of water. Thus, it sets the magnitude of one degree Celsius and that of one kelvin as exactly the same. Additionally, it establishes the difference between the two scales' null points as being precisely 273.15 °C.

In the Hertz per Volt standard the frequency of the note is directly related to the voltage. A pitch of a note goes up one octave when its frequency doubles, meaning that the voltage will have to double for every octave rise. Depending on the footage (octave) selected, nominally one volt gives 1000Hz, two volts 2000Hz and so on. In terms of notes, bottom C would be 0.25 volts, the next C up would be 0.5 volts, then 1V, 2V, 4V, 8V for the following octaves. This system was used mainly by Yamaha and Korg.

SIE
http://qudt.org/vocab/unit/S
S
SI unit for electrical conductance.
Siemens is the SI unit of electric conductance, susceptance, and admittance. The most important property of a conductor is the amount of current it will carry when a voltage is applied. Current flow is opposed by resistance in all circuits, and by also by reactance and impedance in alternating current circuits. Conductance, susceptance, and admittance are the inverses of resistance, reactance, and impedance, respectively. To measure these properties, the siemens is the reciprocal of the ohm. In other words, the conductance, susceptance, or admittance, in siemens, is simply 1 divided by the resistance, reactance or impedance, respectively, in ohms. The unit is named for the German electrical engineer Werner von Siemens (1816-1892).

The SI unit for measuring the flux of light being produced by a light source or received by a surface. The intensity of a light source is measured in candelas. One lumen represents the total flux of light emitted, equal to the intensity in candelas multiplied by the solid angle in steradians into which the light is emitted. A full sphere has a solid angle of 4·π steradians. A light source that uniformly radiates one candela in all directions has a total luminous flux of 1 cd·4π sr = 4π cd·sr ≈ 12.57 lumens. "Lumen" is a Latin word for light.

A WorkPiece is physical artifact, that has a proper shape and occupyes a proper volume intended for subsequent transformation. It is a condensed state, so it is a compact body that is processed or has to be processed.
A solid is defined as a portion of matter that is in a condensed state characterised by resistance to deformation and volume changes.
In manufacturing, a workpiece is a single, delimited part of largely solid material that is processed in some form (e.g. stone ).
In physics, a rigid body (also known as a rigid object[2]) is a solid body in which deformation is zero or so small it can be neglected. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it. A rigid body is usually considered as a continuous distribution of mass.
It has a shape, so we conclude that it is solid

The mole, symbol mol, is the SI unit of amount of substance. One mole contains exactly 6.022 140 76 × 1023 elementary entities. This number is the fixed numerical value of the Avogadro constant, NA, when expressed in the unit mol−1 and is called the Avogadro number. The amount of substance, symbol n, of a system is a measure of the number of specified elementary entities. An elementary entity may be an atom, a molecule, an ion, an electron, any other particle or specified group of particles.

`Ampere hour` is a practical unit of electric charge equal to the charge flowing in one hour through a conductor passing one ampere. An ampere-hour or amp-hour (symbol Ah, AHr, A · h, A h) is a unit of electric charge, with sub-units milliampere-hour (mAh) and milliampere second (mAs). One ampere-hour is equal to 3600 coulombs (ampere-seconds), the electric charge transferred by a steady current of one ampere for one hour. The ampere-hour is frequently used in measurements of electrochemical systems such as electroplating and electrical batteries. The commonly seen milliampere-hour (mAh or mA · h) is one-thousandth of an ampere-hour (3.6 coulombs).

The union of all classes categorising elementary particles according to the Standard Model.
Disjointness comes from the fact that standard model elementary particles are entities that possess objectively distinct and singular characters.
Graviton is included, even if it is an hypothetical particle, to enable causality for gravitational interactions.
This class represents only real particles that are the input and output of a Feynman diagram, and hence respect the E²-p²c²=m²c⁴ energy-momentum equality (on the mass shell).
In the EMMO the virtual particles (off the mass shell), the internal propagators of the interaction within a Feynman diagram, are not represented as mereological entities but as object relations (binary predicates).

SI unit for magnetic flux density or induction.
The SI unit of flux density (or field intensity) for magnetic fields (also called the magnetic induction). The intensity of a magnetic field can be measured by placing a current-carrying conductor in the field. The magnetic field exerts a force on the conductor, a force which depends on the amount of the current and on the length of the conductor. One tesla is defined as the field intensity generating one newton of force per ampere of current per meter of conductor. Equivalently, one tesla represents a magnetic flux density of one weber per square meter of area. A field of one tesla is quite strong: the strongest fields available in laboratories are about 20 teslas, and the Earth's magnetic flux density, at its surface, is about 50 microteslas. The tesla, defined in 1958, honors the Serbian-American electrical engineer Nikola Tesla (1856-1943), whose work in electromagnetic induction led to the first practical generators and motors using alternating current.

The word subjective applies to property intrisically subjective or non-well defined. In general, when an black-box-like procedure is used for the definition of the property.
This happens due to e.g. the complexity of the object, the lack of a underlying model for the representation of the object, the non-well specified meaning of the property symbols.
A 'SubjectiveProperty' cannot be used to univocally compare 'Object'-s.
e.g. you cannot evaluate the beauty of a person on objective basis.
Subjective
A coded conventional that cannot be univocally determined and depends on an agent (e.g. a human individual, a community) acting as black-box.

However, in its broadest sense it can refer to all information (i.e., both programs and data) in electronic form and can provide a distinction from hardware, which refers to computers or other electronic systems on which software can exist and be use.
Here we explicitly include in the definition also all the data (e.g. source code, script files) that takes part to the building of the executable, are necessary to the execution of a program or that document it for the users.

The set of established forms or methods of an organized body for accomplishing a certain task or tasks (Wiktionary).
The process in which an agent works with some entities according to some existing formalised operative rules.
The process in which a control unit of a CPU (the agent) orchestrates some cached binary data according to a list of instructions (e.g. a program).
The process in which a librarian order books alphabetically on a shelf.
The execution of an algorithm.
A procedure can be considered as an intentional process with a plan.

A causal object whose properties variation are encoded by an agent and that can be decoded by another agent according to a specific rule.
A Radio Morse Code transmission can be addressed by combination of perspectives.
Physicalistic: the electromagnetic pulses can be defined as individual A (of type Field) and the strip of paper coming out a printer receiver can be defined as individual B (of type Matter).
Data: both A and B are also DiscreteData class individuals. In particular they may belong to a MorseData class, subclass of DiscreteData.
Perceptual: B is an individual belonging to the graphical entities expressing symbols. In particular is a formula under the MorseLanguage class, made of a combination of . and - symbols.
Semiotics: A and B can be signs if they refers to something else (e.g. a report about a fact, names).
A signal through a cable. A sound wave. Words on a page. The pattern of excited states within a computer RAM.
We call "decoding" the act of recognise the variation according to a particular rule and generate another equivalent schema (e.g. in the agent's cognitive apparatus, as another form of data).
We call "interpreting" the act of providing semantic meaning to data, which is covered by the semiotic perspective.
https://no.wikipedia.org/wiki/Data
Variations in data are generated by an agent (not necessarily human) and are intended to be decoded by the same or another agent using the same encoding rules.
Data are always generated by an agent but not necessarily possess a semantic meaninig, either because it's lost or unknown or because simply they possess none (e.g. a random generation of symbols).
A data object may be used as the physical basis for a sign, under Semiotics perspective.

Np
http://dbpedia.org/page/Neper
Unit of measurement for quantities of type level or level difference, which are defined as the natural logarithm of the ratio of power- or field-type quantities.
The value of a ratio in nepers is given by `ln(x1/x2)` where `x1` and `x2` are the values of interest (amplitudes), and ln is the natural logarithm. When the values are quadratic in the amplitude (e.g. power), they are first linearised by taking the square root before the logarithm is taken, or equivalently the result is halved.
Wikipedia
The neper is a logarithmic unit for ratios of measurements of physical field and power quantities, such as gain and loss of electronic signals. It has the unit symbol Np. The unit's name is derived from the name of John Napier, the inventor of logarithms. As is the case for the decibel and bel, the neper is not a unit in the International System of Units (SI), but it is accepted for use alongside the SI. Like the decibel, the neper is a unit in a logarithmic scale. While the bel uses the decadic (base-10) logarithm to compute ratios, the neper uses the natural logarithm, based on Euler's number
