The usage of social theories in the human-built environment caused to enhance life quality. It may consist of human needs in residential areas. Sometimes, building codes can help to exist accepted life space, but the building codes do not have basic theory such as actual open space in residential plots. The study was an attempt to represent a new approach in urban land subdivision and the relat...

I NTROD UCTlO N lnteroperability of space data systems is of great concern to Space Agencies because sharing or reusing interoperable resources among multiple projects and multiple Agencies can reduce the cost of developing and operating space data systems. However, an on-going problem is that each space data system often has a different architecture and therefore the elements of one system can...

Practically, some intermediary realizations are used in order to simulate, numerically, dynamic systems. One of the most popular is the state-space realization. It reveals to be very useful to study the impact of Finite Word Length implementation, especially in the case of embedded controller. Numerous works concerned the design of the ”best” realization concerning parameterisation, numerical n...

A solution is presented for the problem of realizing a minimal state-space model of an LTI discrete-time system from a partial expansion in terms of generalized orthonormal basis functions, also known as Hambo basis functions. For the solution of the minimal partial realization problem fruitful use is made of the Hambo operator transform theory that underlies the basis function expansion. The r...

In this paper, we study the Chebyshev property of the 3-dimentional vector space $E =langle I_0, I_1, I_2rangle$, where $I_k(h)=int_{H=h}x^ky,dx$ and $H(x,y)=frac{1}{2}y^2+frac{1}{2}(e^{-2x}+1)-e^{-x}$ is a non-algebraic Hamiltonian function. Our main result asserts that $E$ is an extended complete Chebyshev space for $hin(0,frac{1}{2})$. To this end, we use the criterion and tools developed by...

This paper presents a technique to identify an affine parameter-dependent model based on a set of LTI models that are identified in local operating points of the varying system. The systems under investigation are mechatronic systems in which the dynamic behaviour is depending on a single varying parameter. By fitting specific pole and zero loci on the poles and zeros of the local LTI models, a...

The authors present a variation of the constraint orthogonalization method proposed by Kim and Vanderploeg [1] for constrained multibody systems. Firstly the theoretical bases of the QTZ decomposition are presented, then it is reported how to apply this methodology to reduce the constraints number and define the independent velocities. A section is dedicated to three different solution methods ...

This report presents a design space mapping of common arithmetic units with a 0.13 μm CMOS process technology. A behavioural vs. structural (gate-level logic) code comparison is made on key arithmetic functions, binary modulo arithmetic is studied and a brief complexity evaluation is made.

This paper summarizes the results of a benchmarking exercise conducted as part of the NASA supported Advanced Satellite Aviation-Weather Products (ASAP) Program. The goal of ASAP is to increase and optimize the use of satellite data sets within the existing FAA Aviation Weather Research Program (AWRP) Product Development Team (PDT) structure and to transfer advanced satellite expertise to the P...

The question how the classical definition of the Smith zeros of an LTI continuous-time singular control system S(E, A, B, C, D) can be generalized and related to state-space methods is discussed. The zeros are defined as those complex numbers for which there exists a zero direction with a nonzero state-zero direction. Such a definition allows an infinite number of zeros (then the system is call...
