The classical antenna synthesis problem is usually posed in one of two ways. The first addresses the problem of finding an aperture distribution which produces a far field that duplicates, or at least approximates, a prescribed pattern. The second involves determining the location and feed characteristics of a finite array of elementary sources which ...

Synthesis of Geometry Proof Problems
Proceedings of the AAAI Conference on Artificial Intelligence, 2014This paper presents a semi-automated methodology for generating geometric proof problems of the kind found in a high-school curriculum. We formalize the notion of a geometry proof problem and describe an algorithm for generating such problems over a user-provided figure.

On the complexity of the design synthesis problem
IEEE Transactions on Systems, Man, and Cybernetics - Part A: Systems and Humans, 1996Presents and analyzes a formal model of a design process, emphasizing the synthesis part. The design artifact description is identified as an algebraic structure. The desired function and constraints are mapped to the artifact description using an evolutionary process that can be visualized as a feedback loop of analysis, synthesis and evaluation.

Problems of Synthesis of Biotechnical Systems
Biomedical Engineering, 2013Contemporary biotechnical systems combining biological and technological elements with a given function are discussed. In addition to convenient control systems, such biotechnical systems provide studies of bioorganisms and biological materials of any origin, as well as their environment.

Interesting Problems in Physical Synthesis
Proceedings of the 2017 ACM on International Symposium on Physical Design, 2017It is a misperception that the Chinese have the same word for crisis as opportunity. Despite that, a technical crisis does present opportunities for researchers and practitioners to solve interesting problems. In this talk we point out two crises: interconnect and runtime, we enumerate interesting physical-synthesis problems arising from these crises ...

On the Synthesis Problem for Optimal Control Systems
SIAM Journal on Control and Optimization, 2000Summary: A new approach to the synthesis problem of optimal controls of feedback type is considered. Algorithms of operating optimal controllers which are able to calculate values of optimal feedbacks during each particular control process in real time are described. The algorithm of operating the controller of the first type (continuous controller) is

A system is often modeled by a description of its observable behavior, that is, global states and steps. However, to implement a system, it is often more practical to identify local state components and actions whose cause and effect are limited to a few state components. At first, we will discuss this problem using the example of the light/fan system,

The situations within which scientists and technologists act, above all those regarding the technology of naturoids, are surely complicated, permanently, by our incapacity to place ourselves simultaneously at more than one observation level. Though scientific methodology has developed several techniques for controlling more than one variable, de facto ...

Graph fragmentation problem: analysis and synthesis
International Transactions in Operational Research, 2018AbstractVulnerability metrics play a key role in the understanding of cascading failures and target/random attacks to a network. The graph fragmentation problem (GFP) is the result of a worstâcase analysis of a random attack. We can choose a fixed number of individuals for protection, and a nonprotected target node immediately destroys all reachable ...
