Maximum Exposure

Abstract. The Sympson-Hetter (1985) method provides a means of controlling maximum exposure rate of items in Computerized Adaptive Testing. Through a series of simulations, control parameters are set that mark the probability of administration of an item on being selected. This method presents two main problems: it requires a long computation time for calculating the parameters and the maximum exposure rate is slightly above the fixed limit. Van der Linden (2003) presented two alternatives which appear to solve both of the problems. The impact of these methods in the measurement accuracy has not been tested yet. We show how these methods over-restrict the exposure of some highly discriminating items and, thus, the accuracy is decreased. It also shown that, when the desired maximum exposure rate is near the minimum possible value, these methods offer an empirical maximum exposure rate clearly above the goal. A new method, based on the initial estimation of the probability of administration and the probability of selection of the items with the restricted method ( Revuelta & Ponsoda, 1998 ), is presented in this paper. It can be used with the Sympson-Hetter method and with the two van der Linden's methods. This option, when used with Sympson-Hetter, speeds the convergence of the control parameters without decreasing the accuracy.

Abstract:The monitoring and treatment of patients in a care unit is a complex task in which even the most experienced clinicians can make errors. A hemato-oncology department in which patients undergo chemotherapy asked for a computerized system able to provide intelligent and continuous support in this task. One issue in building such a system is the definition of a control architecture able to manage, in real time, a treatment plan containing prescriptions and protocols in which temporal constraints are expressed in various ways, that is, which supervises the treatment, including controlling the timely execution of prescriptions and suggesting modifications to the plan according to the patient’s evolving condition. The system to solve these issues, called SEPIA, has to manage the dynamic, processes involved in patient care. Its role is to generate, in real time, commands for the patient’s care (execution of tests, administration of drugs) from a plan, and to monitor the patient’s state so that it may propose actions updating the plan. The necessity of an explicit time representation is shown. We propose using a linear time structure towards the past, with precise and absolute dates, open towards the future, and with imprecise and relative dates. Temporal relative scales are introduced to facilitate knowledge representation and access.

Computerized System

A system was built up around a minicomputer to process in real time pressure and flow signals collected during the course of three ventilatory mechanics tests: the calculation of the lung volume, the evaluation of the static lung compliance, the analysis of the forced expiratory performance. The subject is seated in an open body Plethysmograph, which allows for the instantaneous calculation of changes in the volume of his thorax and abdomen. The system is controlled through a graphics console which displays the sampled curves and the results of data processing. In addition, the signals can be stored on demand onto a magnetic tape so that the method can be tested and improved off line. The results obtained in healthy volunteers are highly reproducible. A close correspondence is found both in patients and volunteers between computer-derived and hand-calculated results. The computerized system has become a standard equipment of our Lung Function Department, where it allows for a rapid quantitative analysis of lung volumes, lung elasticity and bronchial airflow.

Abstract: The rapid development of the number of islamic banks should be balanced with the availability of infrastructure to carry out daily operational practices. The operational tools include hardware as like as representative office, computerized system, reliable human resources and software as like as method, culture and financial and islamic banking knowledge. In terms of development of Islamic finance is the paper "Alternative Calculation of Return Shahibul Mal on Mudharabah Scheme on Bank Syariah" was written. During this calculation of return shahibul mal has not been standardized in a formula, thus causing two serious effects. First, in the theoretical level, the formula has not yet created a difficulty. Secondly, in practical level, the formula is not impressive enough to recalculate the complexity of return calculations obtained by shahibul mall, causing laziness of the community using the services of islamic bank. This paper using mathematical and arithmetic equations with the help of modeling made by the author to refine and improve the method of calculation that has been available. The purpose of this paper is to create a standard formula that facilitates the calculation of return earned by a shahibul mal in a mudaraba scheme in a islamic bank.

This study aims to explore the financial management practices ofsmall-and-medium-enterprises (SMEs) in the Greater Jakarta (Jabodetabek). We investigate into 3 SME cases by conducting the semi-structured interviews with the owner-managers and using direct observations to know the practices of financial management of SMEs. Through the research, we have found six propositions related to the practice of short-term financial management. They apply bootstraps to ensure availability of working capital. They set aside cash reserves from retained earnings and minimize loans from financial institutions. They have the computerized system to track receivables facilitating working capital needs. They keep theirinventory control efficient to manage working capital. They screen customers using transactional records and reputations to minimize the risk of bad debts.
