the phenomenological model of khossravi and connors (1992) has been adopted to calculate the electrophoretic mobility of drugs at different concentrations of solvents in a binary mixture. the accuracy and predictability of the model have been evaluated employing 14 experimental data sets by using average percentage mean deviation (apmd). the obtained apmd for correlative and predictive studies ...

To support roaming, access control, and different optimizations in the network architecture, a new distributed control and management framework, shown in Figure 1, is required. The basis of this framework is a unified signalling architecture that is capable of serving different entities, located either in the network or in the terminals controlled by different players (terminals by the user, ne...

Information from the sky is important for rescue activity in large-scale disaster or dangerous areas. Observation system using a balloon or an airplane has been studied as an information gathering system from the sky. A balloon observation system needs helium gas and relatively long time to be ready. An airplane observation system can be prepared in a short time and its mobility is good. Howeve...

-To increase mobility and stability under real conditions and achieve superior performance related to walking robots that can travel on land with a configuration as close to real situations as possible, this paper presents studies and research for the integration of additional functions for the compliant control of HFPC walking robots. Starting from the basic functions of the control system, hy...

Ad hoc On Demand distance Vector (AODV) routing protocol is one of the most prominent routing protocol used in Mobile Ad-hoc Networks (MANETs). Due to the mobility of nodes, there exists many revisions as scenarios leading to the loop formation were found. We demonstrate the loop freedom property violation of AODVv2-11, AODVv2-13, and AODVv2-16 through counterexamples. We present our proposed v...

The mobility management issue in IP access networks can be dealt with from various perspectives. A possible approach includes the use of the Session Initiation Protocol (SIP) and its associate entities for mobility signaling. Following this approach, existing SIP functionality in a network can be reused for mobility management purposes, providing efficient utilization of resources. In this pape...

The travel patterns of senior citizens in Seoul were analyzed using Automatic Fare Collection (AFC) data. The focus was specifically on mode choices and transfer patterns. The results showed that 99% of trips made by senior citizens (individuals over 65 years old), who were given free subway transit passes, consisted of single-mode trips. The average travel time was 31 minutes, and subway trave...

Young children with severe motor impairments face a higher risk of secondary impairments in the development of social, cognitive, and motor skills, owing to the lack of independent mobility. Although power wheelchairs are typical tools for providing independent mobility, the steep learning curve, safety concerns, and high cost may prevent children aged 2 to 5 years from using them. We have deve...

Wireless ATM is enjoying enormous research interest in the last few years, because of its ability to combine multimedia applications support, together with the freedom of mobility. One of the key design issues is the medium access control (MAC) protocol for the radio interface. This paper presents the traffic scheduling algorithm used in the MAC protocol of the Wireless ATM Network Demonstrator...

This paper described design and architecture of our own innovative work about the Mobility Management in Wireless Body Area Network for Patient Monitoring System. This system will have the capability to monitor physiological parameters from multiple patient bodies. The system uses the Licence free MICS band between the sensor nodes and a remote central control unit (CCU) that behaves as a base ...
