Title: Machine-implementable method and system for encoding/decoding variables in engineering problems

Description:
FIELD OF THE INVENTION 
     The present invention relates to the selection of variables in engineering problems. More in particular, the present invention relates to a machine-implementable method and system for the selection of dependent and independent variables to form dimensionless quantity equations. 
     BACKGROUND OF THE INVENTION 
     Some engineering problems have unknown sets of partial differential equations, and in those problems, one relies on the Buckingham theorem where dimensionless products of quantities are formed from the set of variables that the engineer has identified. Application of the theorem results in a reduction of the number k of dimensional variables in n dimensional units to a set of (k-r) dimensionless products where r is the rank of the n×k dimensional matrix. So, the engineer starts with a formal description of the problem f(x 1 , . . . x k )=0, obtains a formal description of lower complexity, and thus reduces the computational load, through the equation F(Π 1 , . . . Π (k-r) )=0 that can further be reduced to Π 1 =g(Π 2 ,Π 3 , . . . Π (k-r) ). The problem is to make a good choice between the dependent and independent variables and subsequently their associated dimensionless products. Engineers for real world problems make use of the International System of Units (Système International d&#39;Unités, SI) where the number of units is given by n=7. Most theoretical physicists use a length, mass, and time unit system where n=3. 
     Other sciences use different unit systems. In all problem descriptions, the scientists start with a finite set of base quantities. Those scientists agree by convention to associate to each base quantity a base unit. The convention of the International System of Units recommends scientists and engineers to use seven base quantities: length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity. These quantities make up the International System of Quantities (ISQ). 
     The term dimension of a physical quantity refers to the expression of the dependence on the base quantities of a system of quantities as a product of powers of factors corresponding to the base quantities, omitting any numerical factor. The factors in the dimension are the symbols of the base quantities of the chosen system of quantities. 
     The symbols representing the dimensions of the base quantities in the ISQ are found in Table I.

     In the ISQ, we denote the dimension of a quantity Q by the equation: 
         dim Q=L   α   M   β   T   γ   I   δ Θ ε   N   ζ   Jη 
 
     The dimensional exponents of the known SI quantities take values in the following sets of integers: 
     α takes values from {−3, −2, −1, 0, 1, 2, 3, 4}; 
     β takes values from {−3, −2, −1, 0, 1}; 
     γ takes values from {−4, −3, −2, −1, 0, 1, 2, 3, 4, 6, 7, 10}; 
     δ takes values from {−2, −1, 0, 1, 2, 3, 4}; 
     ε takes values from {−4, −1, 0, 1}; 
     ζ takes values from {−1, 0, 1}. 
     η takes values from {0, 1}. 
     For example, the dimension of the kind of quantity ‘energy’ E is denoted by: 
         dim E=L   2   M   1   T   −2   I   0 Θ 0   N   0   J   0 .
 
     The kind of quantity ‘energy’ is an element of the set of kinds of quantities to which different labels can be assigned: potential energy, electric energy, kinetic energy, thermal energy, . . . . 
     The formal mathematical framework for manipulating quantity equations is quantity calculus. 
     The simplest non-trivial quantity equation with lowest complexity has the form Z=f(Π)XY where X, Y, Z are kinds of physical quantities and f(H) is a function of a dimensionless quantity H. For example, Newton&#39;s law as a quantity equation is given by the equation: force=mass×acceleration.

     In some preferred embodiments, step b) comprises the steps of:
         calculating for each of the w integer lattice points their respective w orbit representative orb(x i ), by taking the absolute value of the coordinates of the integer lattice point x i =(x 0   i |x 1   i , . . . ,x n   i ), sorting them in decreasing order and renaming the coordinates such that orb(x i )=(z 0   i |z 1   i , . . . ,zη i ) where z 1   i ≥z 2   i ≥ . . . ≥z n   i  and where i∈{1, . . . , w};   calculating for the w orbit representatives their respective degree d i , where i∈{1, . . . , w};   identifying the orbit representative with the largest degree, denoting it y, and recalling its associated integer lattice point denoted as x s , such that y=orb(x s );   encoding each orbit representative orb(x i ) using the prescription:

     The number of distinct cardinalities for card({orb(x)}) that can occur in an integer lattice of dimension n is finite. These results are published in the OEIS A270950 with sequence: a(n)=1,1,2,5,9,12,20,29,40,53,76,99,132,172,216,270,341,750 . . . . 
     The largest known published value a(17)=750 occurs for an integer lattice with dimension n=17. The trivial cardinality for the origin being 1 is not counted in A270950. For engineering purposes, the dimensions vary from 
     n=2 to n=7. 
     The cardinalities of the orbits of Aut(   2 ) are 1, 4, 8. 
     The cardinalities of the orbits of Aut(   3 ) are 1, 6, 8, 12, 24, 48. 
     The cardinalities of the orbits of Aut(   4 ) are 1, 8, 16, 24, 32, 48, 64, 96, 192, 384. 
     The cardinalities of the orbits of Aut(   5 ) are 1, 10, 32, 40, 80, 160, 240, 320, 480, 640, 960, 1920, 3840.

     In a first aspect, the invention relates to a machine-implementable method, preferably a computer-implemented method, for forming quantity equations from a selection of sets of dependent and independent variables, comprising the steps of:
         a) defining an input from a selection of a set or sets of dependent and independent variables, the input comprising a list of quantities, for example physical quantities;   b) processing said input, comprising the steps of encoding and decoding of dimensionless groups in an integer lattice, preferably using integer factorization techniques, thereby obtaining a system of quantity equations, the quantity equations comprising the quantities; and,   c) presenting the system of quantity equations as output.       

     The disclosed method is significantly more advantageous in computing efficiency and efficacy as visualized by its output in  FIG.  2   . By way of comparison, a‘brute-force’ calculation based on walks in the integer lattice    2 ×   n  to explore relations between integer lattice points using statistical techniques results in a histogram given in  FIG.  1   . Moreover, the disclosed method contains an automatic selection of the independent variables, unlike the Buckingham theorem where the user must select the independent variables based on his experience or skill. This could lead to a false modelling of the engineering problem, requiring the re-iteration of all the calculations resulting in a waste of time and computing resources. 
     The disclosed method is computing efficient as it is based on low complexity, high performing, and well-established computer algorithms of number theoretic functions. The computer efficacy of the disclosed method is very high as it maps, based on the similitude principle, for example 1680 engineering problems to 1 canonical problem as given in a particular embodiment of the first order partial derivative of the power density with respect to time. The computer efficacy depends on the choice of the quantity and the number of base quantities. The computer efficacy ratios for quantities expressed in SI units are the finite set {28, 168, 256, 336, 560, 896, 1120, 1344, 1680, 1792, 3360, 4480, 5376, 6720, 8960,10752,13440,17920,26880,35840,40320,53760,80640, 107520, 161280, 215040, 322560, 645120, 1290240}. 
     In some embodiments, the method comprises the step of choosing a list of quantities by selecting and ordering n base quantities. 
     The base quantities may be chosen freely, but are preferably selected from the 7 base SI quantities. The present method allows for other choices to be made, resulting in a different meaning of the quantity equations. The present method mainly relates to the syntax of the quantity equations, while the semantics will depend on the chosen base quantities and the order chosen. 
     The semantics depend on the theory upon which the present method is applied. 
     In particular, the step of choosing a list of quantities and ordering n base quantities may be performed according to: time, length, electric current, mass, thermodynamic temperature, amount of substance, luminous intensity; based on the cardinality of the sets of values of each base quantity. More specifically, the set (or sets) of values with the largest cardinality are preferably first in the order as the largest cardinality becomes the exponent of the smallest prime number in the representation. The outlined strategy for ordering the n base quantities leads to higher efficiency as the numbers generated by the coding become smaller. 
     In some embodiments, the method comprises the step of selecting w quantities to be analyzed where w is a natural number. 
     In some embodiments, the method comprises the step of comparing the w quantities to a ‘kind of quantity’ database to determine the corresponding integer lattice point of    2 ×   n . As used herein, the term ‘kind of quantity’ database refers to records containing many relevant fields to the ‘kind of quantity’, such as the cardinality of the orbit representative, the infinity norm, the 1-norm, the orthant in the lattice name of the kind of quantity, an identifier within the orbit, the Conway identifier of the orbit, the lattice vertex coordinate, the sum of coordinates, etc. 
     In some preferred embodiments, quantity is selected that maps to the orbit representative with integer lattice point x=(0|n, n−1, . . . ,1) of    2 ×   n  of largest cardinality equal to the order 2(2 n n!) of the integer lattice    2 ×   n . By selecting this specific integer lattice point, the smallest lattice can be created, on which all the symmetries of the lattice can act. The number of symmetries 2(2 n n!) corresponds to the number of signed permutation matrices that can act on the lattice points. 
     In some embodiments, the method comprises the step of calculating for each of the w integer lattice points their respective orbit representative orb(x i ), by taking the absolute value of the coordinates of the integer lattice point x i =(x 0   i |x 1   i , . . . , x n   i ), sorting them in decreasing order, and renaming the coordinates such that orb(x i )=(z 0   i |z 1   i , . . . ,z n   i ) where z 1   i ≥z 2   i ≥ . . . ≥z n   i  and where i∈{1, . . . , w}. The latter allows for classification of the kind of quantity in equivalence classes, which are represented by orbit representatives, and as such this classification contributes to reduce the number of cases to be studied. 
     In some embodiments, the method comprises the step of calculating for the w orbit representatives their respective degree d i  where i∈{1, . . . , w}. 
     In some embodiments, the method comprises the step of identifying the orbit representative with the largest degree, denoting it y, and recalling its associated integer lattice point denoted as x, such that y=orb(x s ). The latter enables to identify the top of the lattice, which by definition belongs to the set of dependent variables. 
     In some embodiments, the method comprises the step of encoding each orbit representative orb(x i ) using the prescription:

This encoding avoids the creation of ambiguity problems as a consequence of the factorization not being unique. A representative example of the ambiguity in the factorization of prime numbers in a Gaussian lattice is given by prime number 5=(1+2i)(1−2i).

     to obtain an additive partitioning using the respective prime factorizations of each distinct factor F j  and replacing the multiplication operator ‘ x’ by the addition operator ‘+’ obtaining (m+1)-ary vector equations in the integer lattice    2 ×   n . 
     The selected decoding is advantageous because it is based on a fundamental theorem of number theory: the unique prime factorization of a natural number. 
     In some embodiments, the method comprises the step of calculating the (n+1)×(n+1) signed permutation matrix P that maps the orbit representative y to the integer lattice point x s  of    2 ×   n such that y=P where  is the transposed vector of the integer lattice point x s . 
     The step of calculating the (n+1)×(n+1) signed permutation matrix P mapping the orbit y to the integer lattice point x s  of    2 ×   n  such that y=P  needs to be executed only once for all the vector equations of the engineering problem. 
     In some embodiments, the method comprises the step of multiplying each (m+1)-ary vector equations with the (n+1)×(n+1) signed permutation matrix P to obtain the final system of vector equations in the integer lattice    2 ×   n . 
     In some preferred embodiments, the method comprises the steps of:
         selecting the w integers G(orb(x i ));   ordering the divisors sets of the integers G(orb(x i )) in their subsets of equal degree;   building a division lattice for each of the integers G(orb(x i )) by stacking the subsets from low to high degree; and,   taking the union of the w division lattices.       

     The steps outlined above are functional to construct a Hasse diagram. 
     In some preferred embodiments, the method comprises the steps of:
         selecting the p-norm;   calculating the p-norm between all the lattice points generated by the union of the division lattices; and,   visualizing the Euclidean graph for said p-norm of all the lattice points generated by said union of the division lattices.       

     In some preferred embodiments, the method comprises the steps of:
         selecting the 2-norm;   calculating the 2-norm between all the lattice points generated by the union of the division lattices; and,   visualizing the Euclidean graph for said 2-norm of all the lattice points generated by said union of the division lattices.       

     The 2-norm operator is employed as distance metric corresponding to the definition of the Euclidean distance as it defines the distance between two points in a Euclidean n-dimensional space. 
     In some preferred embodiments, the method comprises the steps of:
         selecting the square of the 2-norm;   calculating the square of the 2-norm between all the lattice points generated by the union of the division lattices; and,   visualizing the Euclidean graph for said square of the 2-norm of all the lattice points generated by said union of the division lattices.       

     The square of the 2-norm is preferably employed as only integers are used instead of real numbers, which in turn translates in lower computation demand due to significant less memory usage. 
     In some preferred embodiments, the method comprises the step of:
         creating a system of equations from the vector equations of the integer lattice    2 ×   n , preferably wherein the system of equations comprises algebraic equations, and/or ordinary differential equations, and/or partial differential equations, and/or integro-differential equations.       

     In some preferred embodiments, the method comprises the step of:
         labelling the variables using a lexicon, preferably a lexicon of the SI database, for example the lexicon as provided in Tables III to XVIII.       

     The usage of the lexicon as provided in Tables III to XVIII referring to the present status of all published SI physical quantities supports the user to provide (semantic) meaning to the equations generated by the computer. 
     In some preferred embodiments, the lexicon is based on another system of units than the SI database. 
     Another system of units is the MKSA system where only 4 base quantities are used for the description of engineering problems. NIST proposed a 7 base quantity system using: frequency, velocity, action, electric charge, heat capacity, amount of substance and luminous intensity. In the NIST system the kind of quantity energy has the coordinate (0|1,0,1,0,0,0,0) with code=6 instead of the SI coordinate (0|2,1,−2,0,0,0,0) with code=180. It is particularly advantageous to perform the choice of NIST versus the SI system, as its code results in a smaller number, which in turns allows for the energy to become an independent variable in many engineering problems. 
     In some preferred embodiments, step c) comprises one or more of the steps of:
         updating a global lexicon or dictionary with the output of the method as described herein, or embodiments thereof;   analyzing the results through viewing information, visualizations, graphs, tables, and the like; and,   optionally, providing extra information if the quantity equations are known.       

     The visualization step provides the user with a pictorial approach to the diagrams instead of the algebra. This visualization allows a holistic approach to the engineering problem. After the results have been obtained, they can be added to the global lexicon or dictionary. The end-user can view information, visualizations, graphs, tables, etc. related to the quantity equation. If the quantity equation is known, extra information can be provided.

     EXAMPLES 
     Example 1 
     In the present example, the disclosed method is applied, for the sake of simplicity, to a formula with w=1 where this quantity Q represents the first order partial derivative of the power density with respect to time, and where we postulate the quantity equation f(Q)=0. This case is a technical problem where the set of partial differential equations is unknown. It is technically relevant as this problem governs the future of power grids where wind turbine power and photovoltaic power is connected to the classical power grid where the power comes from a steam plant, a gas turbine, or a nuclear power plant. Those power conversions are dynamical variables that are distributed in space, and thus best described by the first order partial derivative of the power density with respect to time. 
     The disclosed method will search for the dependent and independent variables that are connected to the first order partial derivative of the power density with respect to time. 
     The dimension of the kind of quantity ‘time derivative of the power density’ is denoted by: 
         dim Q=L   −1   M   1   T   −4   I   0 Θ 0   N   0   J   0 .
 
     To make a difference between physical quantities that transform like tens or pseudo-tensors, we consider the cartesian product    2 ×   7 , where    2 =( /2 ) is the set {0,1}, and represent the kind of quantity ‘time derivative of the power density’ as the integer lattice point x=(0|−1,1,−4,0,0,0,0) and abbreviate it using the Conway notation to x=(0|−1,1, −4, 0 4 ) when needed. 
     We encode the ‘time derivative of the power density’ by determining the orbit representative orb(x)=(0|4,1,1,0,0,0,0) that is an integer lattice point of the positive orthant of    2 ×   7 . 
     We map the integer lattice point of    2 ×   7  to the integer G(orb(z)) of 7 according to the following encoding prescription: 
         G (orb( z ):=(−1) z     0     p   1   z     1      . . . p   7   z     7    
 
     of the orbit representative orb(z) in the lattice    2 ×   7  where p i   z     i    is the z i -th power of the i-th prime number, such that G((0|4,1,1,0,0,0,0))=(−1) 0 2 4 3 1 5 1 7 0 11 0 13 0 17 0 =240. 
     This number is known as a highly composite number. Its primorial factorization is 240=2 3 ×30. The degree of the orbit representative orb(z) is calculated through the formula deg(orb(z))=z 1 +z 2 + . . . +z 7  and thus deg(orb(x))=6. 
     The number of divisors of  240  is T(240)=20. The set of these divisors is 10 {1,2,3,4,5,6,8,10,12,15,16,20,24,30,40,48,60,80,120,240}. 
     We perform the factorization of the number 240 in m distinct factors and obtain the following: 9 factorizations in 2 distinct factors, 12 factorizations in 3 distinct factors, and 3 factorizations in 4 distinct factors. Factorizations of natural numbers from 1 to 10000 in m distinct factors is tabulated in the On-Line Encyclopaedia of Integer Sequences (OEIS) with identifier A045778. 
     We apply a decoding prescription that maps each divisor of G(orb(x)) being an element of Z to the positive orthant of the integer lattice    2 ×   7 : 
         G ( orb ( z )):=(−1) z     0     p   1   z     1     . . . p   7   z     7   →( z   0   ,z   1   . . . ,z   7 )
 
     This decoding creates a cluster of 20 integer lattice points in    2 ×   7 . The lattice points can be grouped in deg(orb(x))+1 distinct sets. These 7 sets ordered in increasing degree are: 
     S 0 ={(0|0,0,0,0,0,0,0)}, 
     S 1 ={(0|1,0,0,0,0,0,0), (0|0,1,0,0,0,0,0), (0|0,0,1,0,0,0,0)}, 
     S 2 ={(0|2,0,0,0,0,0,0), (0|1,1,0,0,0,0,0), (0|1,0,1,0,0,0,0), (0|0,1,1,0,0,0,0)}, 
     S 3 ={(0|3,0,0,0,0,0,0), (0|2,1,0,0,0,0,0), (0|2,0,1,0,0,0,0), (0|1,1,1,0,0,0,0)}, 
     S 4 ={(0|4,0,0,0,0,0,0), (0|3,1,0,0,0,0,0), (0|3,0,1,0,0,0,0), (0|2,1,1,0,0,0,0)}, 
     S 5 ={(0|4,1,0,0,0,0,0), (0|4,0,1,0,0,0,0), (0|3,1,1,0,0,0,0)}, 
     S 6 ={(0|4,1,1,0,0,0,0)}. 
     The visualization of the Hasse lattice containing the 7 sets is given in  FIG.  2   . 
     Each m-factoring yields an additive partitioning of the orbit representative orb(x) that is equivalent to a multiplicative (m+1)-ary equation. 
     The 4-factoring results in 3 quinary equations. The factorizations are: 
       240=2×3×4×10=2×3×5×8=2×4×5×6

     that represents the number of distinct elements in the set {orb(x)}. 
     The disclosed method achieves the modelling of 1680 different engineering problems to be expressed in 1 structure containing 24 canonical vector equations based on their geometrical similitude. So, instead of solving 1680×24=40320 vector equations in the computer, we reduce the problem to solving only 24 vector equations. This has a significant impact on computing time and power usage. 
     To each of the 1680 vectors y, representing the individual engineering problems, exists a unique signed permutation matrix P that maps the lattice point x=(0|4,1,1,0,0,0,0) to the lattice point y. 
     For the case of the time-derivative of the power density we find the 8×8 signed permutation matrix P:

     Applying the matrix P to each of the 24 vector equations, yields a new set of 24 vector equations that provides the structure searched for by the engineer/scientist. The semantic interpretation of the vector equations relies on the experience of the engineer/scientist. The engineer/scientist has the possibility to connect to a database containing a lexicon/dictionary of known quantities with their associated lattice point cluster. 
     In the present example, we list searched equations for the case of the first order partial derivative of the power density with respect to time, that is equivalent to the second order derivative of the energy density W with respect to time and its associated dimensional equation, where the symbols are taking from the dictionary or lexicon (Table III to Table XVII) of the SI database and have the following interpretation: W the energy density,

     Example 2 
     Another embodiment of the present invention is the application of the disclosed method to the kind of quantity energy E. The kind of quantity energy has the coordinates E=(0|2,1, −2,0,0,0,0) expressed using the 7 SI base units as m 2 ·kg 1 ·s −2 ·A 0 ·K 0 ·mol 0 ·cd 0 . Its orbit representative has the coordinate (0|2,2,1,0,0,0,0) in    2 ×   7 . The encoding of the orbit representative yields G((0|2,2,1,0,0,0,0))=(−1) 0 2 2 3 2 5 1 7 0 11 0 13 0 17 0 =180. 
     This number is known as a highly composite number. Its primorial factorization is 180=6×30. 
     The number of divisors of 180 is τ(180)=18. The set of the divisors of 180 is {1,2,3,4,5,6,9,10,12,15,18,20,30,36,45,60,90,180}. 
     The decoding creates a cluster of 18 integer lattice points in    2 ×   7 . 
     The degree of the orbit representative is deg(orb(E))=5 resulting in 6 subsets of the divisors set of 180. 
     These 6 sets ordered in increasing degree are: 
     S 0 ={(0|0,0,0,0,0,0,0)}, 
     S 1 ={(0|1,0,0,0,0,0,0), (0|0,1,0,0,0,0,0), (0|0,0,1,0,0,0,0)}, 
     S 2 ={(0|2,0,0,0,0,0,0), (0|1,1,0,0,0,0,0), (0|0,2,0,0,0,0,0), (0|1,0,1,0,0,0,0), (0|0,1,1,0,0,0,0)} 
     S 3 ={(0|2,1,0,0,0,0,0), (0|1,2,0,0,0,0,0), (0|2,0,1,0,0,0,0), (0|1,1,1,0,0,0,0), (0|0,2,1,0,0,0,0)} 
     S 4 ={(0|2,2,0,0,0,0,0), (0|2,1,1,0,0,0,0), (0|1,2,1,0,0,0,0)}, 
     S 5 ={(0|2,2,1,0,0,0,0)}. 
     The visualization of the Hasse lattice containing the 6 sets is given in  FIG.  4   . 
     The 4-factoring results in 1 quinary equation. The equation is 
       180=2×3×5×6
 
     The 3-factoring results in 8 quaternary equations. The equations are

     The symbols used in the column quantity equation are taken from the dictionary or lexicon (Table III to Table XVIII) of the SI database and have the following interpretation: E i  energy, s displacement, t time, ω angular frequency, m mass, A area, v speed, F force, L total angular momentum, p linear momentum, a acceleration and f i (Π i ) function of dimensionless variable. 
     For the case of the kind of quantity energy we find the 8×8 signed permutation matrix P:

     Example 3 
     Another embodiment of the disclosed method applied to the field of electromagnetism is the encoding of the vector potential {right arrow over (A)} with number G(orb(A))=(−1) 0 2 3 3 2 5 1 7 1 11 0 13 0 17 0 =2520. 
     This number is known as a highly composite number. Its primordial factorization is 2520=2×6×210. 
     The decoding of the vector potential {right arrow over (A)} is summarized through the Hasse diagram given in  FIG.  5   .
