BACKGROUND Since tumors located in thorax region of body mainly move due to respiration, in the modern radiotherapy, there have been many attempts such as; external markers, strain gage and spirometer represent for monitoring patients' breathing signal. With the advent of fluoroscopy technique, indirect methods were proposed as an alternative approach to extract patients' breathing signals. M...

In 1955, the first nuclear medicine division was established in Thailand by Professor Romsai Suwannik in the Department of Radiology, Siriraj Hospil, Mahidol University in Bangkok. In 1959 four years later, the second nuclear medicine division was established in the Department of Radiology, Chulalongkorn Hospital in Bangkok. The third nuclear medicine division was started in Rajvithi Hospital i...

we give a new proof of the well known wedderburn's little theorem (1905) that a finite‎ ‎division ring is commutative‎. ‎we apply the concept of frobenius kernel in frobenius representation theorem in finite group‎ ‎theory to build a proof‎.

in this paper we study triangularization of collections of matrices whose entries come from a finite-dimensional division ring. first, we give a generalization of guralnick's theorem to the case of finite-dimensional division rings and then we show that in this case the reduced trace function is a suitable alternative for trace function by presenting two triangularization results. the firs...

This paper presents an original solution for flexible hand-written text division into rows. Unlike the standard procedure, the proposed method avoids the isolated characters extensions amputation and reduces the recognition error rate in the final stage.

Standard mathematics involves such notions as infinitely small/large, continuity and standard division. This mathematics is usually treated as fundamental while finite mathematics is treated as inferior. Standard mathematics has foundational problems (as follows, for example, from Gödel’s incompleteness theorems) but it is usually believed that this is less important than the fact that it descr...

Abstract A flexible full-color micro-LED display with high mechanical robustness was fabricated by printing quantum dots (QDs) on a blue array using standard photolithography. The red and green colors yielded from QDs exhibit better color gamut than conventional filters. light conversion efficiency enhanced adding TiO 2 nanoparticles to the QD-photoresist composite. This successfully mounted va...

Suppose that F is a non-Archimedean local field of characteristic not 2 and D central division algebra over F. Let n be positive integer. We show classification modulo essentially square-integrable representations standard modules GLn(D) which have non-zero linear periods. By this classification, the conjecture Prasad Takloo-Bighash reduced to case representations.

Pressure vessel is a container used to store fluids under pressure and temperature. The fluids can be air, water, chemicals, fuel, gases etc. are most commonly used in food and chemical industries, oil refineries and so on. Pressure vessel is subjected to thermal and structural loads for power plant applications. Since the pressure vessel are subjected to both structural and thermal loads stres...
