Background and Objectives: Public-Private Partnership (PPP) is a well-established model to alleviate the risk of investment in health domain. While the model is widely applied in the developed countries, the adoption of the model in many developing countries is hampered partly by the lack of knowledge on dimensions and requirements of its local implementation. The present study...

Absorption spectra and fluorescence properties o f 2,3-dihydro-4( 1 H)-quinolinone deriva­ tives were studied at room temperature in different solvents. It has been found that the fluo­ rescence quantum yields and fluorescence decay times strongly depend on the molecular struc­ ture and solvent polarity. The character and the energy o f excited states were determined by PPP and CNDO /S quantum-...

We study nonlinear control systems in the plane, affine with respect to control. We introduce two sets of feedback equivariants forming a phase portrait PP and a parameterized phase portrait PPP of the system. The phase portrait PP consists of an equilibrium set E, a critical set C (parameterized, for PPP), an optimality index, a canonical foliation and a drift direction. We show that under wea...

the study is focused on the public-private partnership in health sector in sri lanka. as a developing country, sri lanka faces a challenging task in order to improve the infrastructure facilities of the country after ending the thirty years of war. there is a requirement to develop the country as a whole along with all the industries such as education, health, transport, agriculture, etc. to me...

Abstract This paper analyzes candidate schemes for PPP/PPP-RTK (precise point positioning/real-time kinematic) data authentication. Asymmetric are proposed based on existing standards and compatible with GNSS messages. Post-quantum cryptographic signatures also reviewed discussed. Two selected analysis: digital signature (DS) ECDSA, delayed disclosure (DD) a hybrid scheme using the TES...

It is found for the last two decades that there has been a rapid rise of PPPs across the world. A government in developing countries like India is using PPP arrangements for improved delivery of infrastructure services and social services. Public Private Partnerships which are an integral part of the new paradigm of good governance policy is the most recent addition in the world of society and ...

PPP-RTK is integer ambiguity resolutionenabled precise point positioning. In this contribution, we present the principles of PPP-RTK, together with a review of different mechanizations that have been proposed in the literature. By application of S-system theory, the estimable parameters of the different methods are identified and compared. Their interpretation is essential for gaining a proper ...

Multi-constellation global navigation satellite systems (GNSSs) are expected to enhance the capability of precise point positioning (PPP) by improving the positioning accuracy and reducing the convergence time because more satellites will be available. This paper discusses the performance of multi-constellation kinematic PPP based on a multi-constellation kinematic PPP model, Kalman filter and ...

The Point-to-Point Protocol (PPP) over Asynchronous Transfer Mode (ATM) Adaptation Layer 2 defines the encapsulation that allows a PPP session to be transported over an ATM virtual circuit using the ATM Adaptation Layer 2 (AAL2) adaptation layer. This document defines a set of class extensions to PPP over AAL2 that implement equivalent functionality to Multi Class Multi Link PPP over a single A...
