We envisioned the two stages as two stations in a hospital that a patient passes through before completing service. In the first station there are two servers (i.e., nurses) which attend to the patient. When a patient arrives to the first station he/she is served by one of the two servers, the server serves the patient and stays with the customer until the service in the second station of the model is completed. In the second station, another server (i.e., doctor) attends to the customer with the cooperation of first station server. The service rates of the servers and arrival rates of the patients follow exponential distribution. The mathematical model is also used to determine the conditions that allow the patients in system to be served effectively. To estimate the conditions of stability, the steady state probabilities have been calculated and stability behavior has been given for special cases.</p>2013-11-30T00:00:00-06:00http://www.cscanada.net/index.php/sms/article/view/j.sms.1923845220130702.2469Path-Independence of Work Done Theorem Is Invalid in Center-Bound Force Fields2013-12-09T21:16:01-06:00Jakub Czajkosms@cscanada.org<p>Abstract: The notion of work done, and the corresponding to it concept of potential energy, was incompletely defined making the path independence theorem of work done by center-bound force fields invalid for other than radial/conservative forces. Hence nonradial effects along equipotential surfaces, whose presence was suggested by experiments, can exist. New, mathematically complete representation of work done by center-bound force fields (generated by a single source) is offered.</p>2013-11-30T00:00:00-06:00http://www.cscanada.net/index.php/sms/article/view/j.sms.1923845220130702.2752Equipotential Energy Exchange Depends on Density of Matter2013-12-09T21:16:01-06:00Jakub Czajkosms@cscanada.org<p>Abstract: Potential energy exchanged for work done by radial/center-bound gravitational force field along equipotential surfaces (where the radial potential remains unchanged by definition), depends also on density of matter of the source mass that is responsible for generating the locally dominant field. To the extent that equipotential hence nonradial parts of trajectory paths (of the objects that move within the field) are exposed to the (nonrotating) field’s influence, the moving objects’ energy is lost (regardless of direction of the nonradial part of their motion) and transferred to the field. Mathematically derived, with the use of (new) synthetic mathematics, a new law governing nonradial exchange of potential energy generalizes the previous law that has been derived from physical considerations and had already been confirmed by several experiments and observations.</p>2013-11-30T00:00:00-06:00http://www.cscanada.net/index.php/sms/article/view/j.sms.1923845220130702.1760Countably Semiadditive Functionals and the Hardy–Littlewood Maximal Operator2013-12-09T21:25:52-06:00E.

Using these indexes and their ranks, it is shown that the enunciated mandatory upper age limit of 20 years is approximately the mean age of the commercial planes in the country estimated to be 20.7 years, but higher than the median age of the planes found to be 19.4years. Thus if median age of 19.4 or about 19 years rather than 20 years is to be set as the required upper age limit, then only about 33 or 34 rather than 37 commercial planes would be properly eligible to fly Nigeria’s airspace. Statistically significant differences in age are found to exist between commercial planes that may importantly affect their operation. Relative “plane age” indexes that are positive with a value of 17 or larger so that the corresponding planes are younger than at least 42 and older than at most 25 other planes and aged at most 15.3 years are statistically significant; while those relative “plane age” indexes that are negative with a value of at most 20 so that the corresponding planes are younger than at most 23 and older than at least 43 other planes and aged at least 21.2 years are statistically significant. Hence if age is to be considered as a statistical factor affecting air-worthiness of commercial planes, then the upper age limit of 15.3 or 15 years should be preferred and used as a selection eligibility criterion for commercial planes in Nigeria. This will in effect imply that no plane aged above 15.3 years may be allowed to fly resulting in only about 26 commercial planes rather than 37 as is the case under the current dispensation being able to properly and normally use Nigeria’s airspace.</p>2013-11-30T00:00:00-06:00http://www.cscanada.net/index.php/sms/article/view/j.sms.1923845220130702.2483The Dual Space χ2 of Double Sequences2013-12-09T22:00:07-06:00N.
