While not explicitly intended for feature transformation, some methods for switching circuit design implicitly deal with this problem. Given a tabulated Boolean function, these methods construct a circuit that implements that function. In 1950s and 1960s, Ashenhurst [1] and Curtis [2] proposed a function decomposition method that develops a switching circuit by constructing a nested hierarchy o...

Function discovery is the problem of nding a symbolic formula for a function f : D1!D2 from a set of examples f(x; y) j y = f(x)g D1 D2. Acceptable solutions are restricted to formulas expressible in some given description language L. In most previous discovery systems|for example, Bacon [4], Abacus [1], Coper [2], Fahrenheit [3] and IDS [5]|the description language is restricted to contain onl...

in protein biochemistry, biochemists specially study proteins as complex polymers. protein biochemistry is the study of the chemical structure of proteins, including individual amino acids, their linkage as well as physical structure of proteins. proteins, especially globular proteins, are three dimensional in nature. proper function of globular proteins is tightly related to their three-dimens...

in this paper energy bands and berry curvature of graphene was studied. desired hamiltonian regarding the next-nearest neighbors obtained by tight binding model. by using the second quantization approach, the transformation matrix is calculated and the hamiltonian of system is diagonalized. with this hamiltonian, the band structure and wave function can be calculated. by using calculated wave f...

we consider the space of weakly almost periodic functions on a transformation semigroup (s, x , ?) and show that if x is a locally compact noncompact uniform space, and ? is a separately continuous, separately proper, and equicontinuous action of s on x, then every continuous function on x, vanishing at infinity is weakly almost periodic. we also use a number of diverse examples to show that th...

One of the important functions of every Semiotic system is its local function. In a discourse, places have various roles such as objective, acting, being, abstract, narrative and mythical. In addition they have referential, narrative, tensional, metaphorical and transcendental functions and they play a role in creation of meaning. By strengthening objective and physical aspects of place, its co...
