National agricultural extension and advisory systems have undergone major changes during the past two decades. These changes have been attributed to the success of the Green Revolution, commercialisation of agriculture and trade liberalization. In addition, transnational corporations develop a wide range of new technologies, which directly impact on agricultural production in developed and deve...

This memo presents a set of extensions for supporting generic policy based admission control in RSVP. It should be perceived as an extension to the RSVP functional specifications [RSVP] These extensions include the standard format of POLICY_DATA objects, and a description of RSVP’s handling of policy events. This document does not advocate particular policy control mechanisms; however, a Router...

as an assessment method of the water resources, water poverty index (wpi) has become an available tool in water resources management. in particular, agricultural water poverty index (awpi) is an assessment tool for agricultural water in rural areas. during the past decades, mahidasht basin in kermanshah province has been declared by water policy makers as “forbidden” basin in terms of water exp...

This paper presents a PCIM-based framework for storing and enforcing RBAC (Role Based Access Control) policies in distributed heterogeneous systems. PCIM (Policy Core Information Model) is an information model proposed by IETF. PCIM permits to represent network policies in a standard form, allowing software from different vendors to read the same set of policy rules. This paper describes a PCIM...

Developing access control extensions for operating systems is an expensive and time-consuming task. Mechanisms available for access control extension lag behind industry standard extension solutions for file systems, process schedulers, and device drivers, and suffer from a number of serious flaws in modern multi-processor, multi-threaded kernels. In this paper, we explore the limitations of cu...

This paper addresses the modelling and evaluation of cell scheduling policies in ATM multiplexers using stochastic Petri nets. In particular, we compare four cell scheduling policies: a FIFO policy with and without non-preemptive priorities, a threshold priority policy as recently proposed by Lee and Sengupta, and an extension thereof. The aim of this paper is twofold. First, we want to stress ...

The growth cycle and labour contract length This paper extends the growth cycle model à la Goodwin (1967) by introducing the risk-averse behaviour of the agents and a consequent positive correlation between wages and profitability. This extension is motivated by the impressive evidence on the joint role played by aggregate unemployment and lagged profitability in explaining wage determination. ...

As an extension to Gou et al.(2007)[7], this paper introduces a modified inventory policy for an open-loop reverse supply chain. The major issue is to determine the economical parameters to minimize the system wide cost. To find the optimal parameters, simulations are utilized. Comparison with the previous policy is also presented.
