WLS design of variable frequency response FIR filters

Abstract: This paper extends the Weighted Least Squares method to designing FIR filters capable of changing, in the real-time, one of their frequency response characteristics (group delay, the width of the passband, resonance frequency or any other). The filter coefficients are polynomial functions of the parameter characterising the variable feature. The computations needed in such designs can be kept at low level if the weight function in the performance criterion is separable. The advantages of the proposed approach are illustrated by a design of a Fractional Sample Delay filter with variable delay. If this filter has to meet demanding specifications then the proposed approach provides a cheaper and more effective solution than traditional approaches based on Lagrange interpolation.

Modelling home care organisations from an operations management perspective

Abstract: Home Care (HC) service consists of providing care to patients in their homes. During the last decade, the HC service industry experienced significant growth in many European countries. This growth stems from several factors, such as governmental pressure to reduce healthcare costs, demographic changes related to population ageing, social changes, an increase in the number of patients that suffer from chronic illnesses, and the development of new home-based services and technologies. This study proposes a framework that will enable HC service providers to better understand HC operations and their management. The study identifies the main processes and decisions that relate to the field of HC operations management. Hence, an IDEF0 (Integrated Definition for Function Modelling) activity-based model describes the most relevant clinical, logistical and organisational processes associated with HC operations. A hierarchical framework for operations management decisions is also proposed. This analysis is derived from data that was collected by nine HC service providers, which are located in France and Italy, and focuses on the manner in which operations are run, as well as associated constraints, inputs and outputs. The most challenging research areas in the field of HC operations management are also discussed.

A comparison of FDI determinants in China and India

Abstract: This study explores foreign direct investment (FDI) determinants in China and India and fills the gap in the literature by providing a comprehensive empirical comparison analysis. Two panel data sets and two statistical models are employed to identify the determinants of FDI inflows from home countries worldwide to the two host countries by considering both home and host countries' characteristics. The empirical results show some interesting similarities and differences between the two countries. Market growth, imports, labor costs, and country political risk/policy liberalization are the determinants for both countries. However, exports, market size, and borrowing costs are important to China's FDI, while geographical and cultural distance factors are important to India's FDI.
