Item A Visual Management System for Universities - A CASE STUDY OF THE UNIVERSITY OF KELANIYA, SRI LANKA(University of Kelaniya, 2006) Sirisena, H.; Hewawitanagamage, U.R.; Munasinghe, J.; Sakalasooriya, N.; Kalansooriya, J.Expansion of the boundaries of human knowledge is the key to enhance the quality of civilizations. Knowledge results in systems. Systems, in turn, make better environments where human beings could maintain high standards of life. We all are aware of the famous saying of Munidasa Kumarathunga, the renowned Grammarian of Sinhala language and patriotic, which states that "A nation cannot achieve success unless new discoveries are made." (alut alut de notanana jaatiya lova nonagi). When we were students we had to face lots of difficulties within the university premises, due to lack of a proper system of visual management. When we became members of the staff as academics and administrative officers we faced more difficulties in regard to above mentioned matter. We experienced this problem specially, when a new batch of students enters the university. Also, in the recent past various fee levying Postgraduate and Diploma courses have been introduced by our faculties and thousands of external students have been registered for undergraduate degrees at CODL. As such, we are in need of a systematic way to handle this mass who interacts with our various academic and administrative departments/branches in the University. When we undertook our Postgraduate Degrees in various foreign countries such as India, Russia, Germany and United Kingdom etc., we have been inspired by the visual management systems displayed by their universities. Certainly they are applying their knowledge to the betterment of their own society. These thoughts inspired us and as a result we have made an attempt to introduce a visual management system for our university. We hope that this kind of visual management system can be applied to any university.Item Anomalous Absorption of Deuteron Partial Waves by Nuclear Optical Potential(University of Kelaniya, 2006) Piyadasa, R.A.D.; Kawai, M.; Munasinghe, J.M.Kawai and Y. Iseri (2), (3) found an interesting phenomenon in nuclear physics, motivated by the work of (1), in case of nucleon-nucleus elastic scattering. In the following this phenomenon is discussed in case of neutron (n)-nucleus (A) elastic scattering. In elastic scattering of neutron on (A), the elastic S – matrix element for a particular combination of j l E A cm , , , becomes very small (almost zero), and they called this phenomenon anomalous absorption of neutron partial waves by nuclear optical potential, where j is the total angular momentum, l is the angular momentum, cm E the centre of mass energy and A the mass of the nucleus. The striking feature of this phenomenon is systematic in various parameter ( f ,l, E , A) cm planes. Among them, systematic in ⎟⎠ ⎞ ⎜⎝ ⎛ 3 1 , A k l plane is actually remarkable, which consists of straight lines. All straight lines correspond to a definite node of wave functions associated with A k E l j cm , , , . It is quite interesting to examine whether this phenomenon occurs in case of composite projectiles such as d , He , etc. Now, it has been shown (4) that this phenomenon is universal. The main purpose of this paper is to report results of the case d − A after being rescrutinized by us. It is striking that the systematic in ⎟ ⎟ ⎠ ⎞ ⎜ ⎜ ⎝ ⎛ + + + 3 1 2 , ( 1) A k η η l l plane is remarkably clearer than the case of neutron. Here, k η + η 2 + l (l +1) , the closest approach is physically meaningful in case of the presence of the Coulomb potential.
