Media Rate Control For Large Scale Immersive Communications, Mohammed Raad, Raad Raad, Farzad Safaei
Dr Raad Raad
A video rate control mechanism based on a modified LMS algorithm is presented. The control mechanism is used within a real-time IP multicast based system. Simulation results show that such a control mechanism allows the system to adapt to the varying network conditions of receiving clients.
Vulnerability Control Of Large Scale Interconnected Power System Using Neuro-Fuzzy Load Shedding Approach, Ahmed Haidar, Azah Mohamed, Aini Hussain
Vulnerability Control Of Large Scale Interconnected Power System Using Neuro-Fuzzy Load Shedding Approach, Ahmed Haidar, Azah Mohamed, Aini Hussain
Dr Ahmed Mohamed Ahmed Haidar
Vulnerability control is becoming an essential requirement for security of power systems in the new utility environment. It is a difficult task for system operator who under economic pressure may be reluctant to take preventive action against harmful contingencies in order to guarantee providing continued service. For power systems which are operated closer to their stability limits, it is desirable to use load shedding as a form of vulnerability control strategy. This paper presents a neuro-fuzzy approach for determining the amount of load to be shed in order to avoid a cascading outage. The objective is to develop fast and …

Smart Control Of Upcq Within Microgrid Energy System, C Benachaiba, Ahmed Haidar, O Habab, O Abdelkhalek
Dr Ahmed Mohamed Ahmed Haidar
One of the most popular issues in the future power distribution is the quality improvement of microgrid and the development of smart grid (SG). Many applications operating at the microgrid level can be considered as smart grid functions. This paper proposes the application of Fuzzy Logic (FL) technique within microgrid energy system based on the most modern power conditioning equipment devices such as Unified Power Quality Conditioner (UPQC). This technique is working together with the microgrid to track the disturbance of the smart grid and improve the quality of the system with a high flexibility. Furthermore, a control methodology developed …

Privacy-Preserved Access Control For Cloud Computing, Miao Zhou, Yi Mu, Willy Susilo, Man Ho Allen Au, Jun Yan
Privacy-Preserved Access Control For Cloud Computing, Miao Zhou, Yi Mu, Willy Susilo, Man Ho Allen Au, Jun Yan
Dr Jun Yan
The problem of access control on outsourced data to "honest but curious" cloud servers has received considerable attention, especially in scenarios involving potentially huge sets of data files, where re-encryption and re-transmission by the data owner may not be acceptable. Considering the user privacy and data security in cloud environment, in this paper, we propose a solution to achieve flexible and fine-grained access control on outsourced data files. In particular, we look at the problem of defining and assigning keys to users based on different attribute sets, and hiding access policies as well as users information to the third-party cloud …
A Novel Control Strategy For Stand-Alone Operation Of A Wind Dominated Raps System, Sarath Perera, Kashem Muttaqi, Nishad Mendis, M.N Uddin,
A Novel Control Strategy For Stand-Alone Operation Of A Wind Dominated Raps System, Sarath Perera, Kashem Muttaqi, Nishad Mendis, M.N Uddin,
Associate Professor Kashem Muttaqi
This paper presents a novel control strategy for a high penetrated wind based hybrid Remote Area Power Supply (RAPS) system. The proposed RAPS system consists of a Permanent Magnet Synchronous Generator (PMSG) based variable speed wind turbine and a battery energy storage system with a dump load for DC bus voltage control and a diesel generator as a back-up supply. An integrated control approach based on active and reactive power balance of the proposed RAPS system has been proposed and developed with a view to regulate the voltage and frequency within an acceptable bandwidth. The proposed integrated control algorithm is …

Vibration Control Of Seat Considering Vehicle Suspension And Human-Body Models, Haiping Du, Weihua Li, Nong Zhang
Vibration Control Of Seat Considering Vehicle Suspension And Human-Body Models, Haiping Du, Weihua Li, Nong Zhang
Dr Haiping Du
Vehicle seat suspension is one of very important components to provide ride comfort, in particular, commercial vehicles, to reduce driver fatigue due to long hours driving. This paper presents a study on active control of seat suspension to reduce vertical vibration transmitted from uneven road profile to driver body. The control problem will be firstly studied by proposing an integrated seat suspension model which includes vehicle chassis suspension, seat suspension, and driver body model. This is a new concept in the field of study because most of the current active and semi-active seat suspension studies only consider seat suspension or …
Novel Association Control Strategies For Multicasting In Relay-Enabled Wlans, Kwan-Wu Chin, Shinan Li
Novel Association Control Strategies For Multicasting In Relay-Enabled Wlans, Kwan-Wu Chin, Shinan Li
Associate Professor Kwan-Wu Chin
Multicast is a fundamental communication service in Wireless Local Area Networks (WLANs). Unfortunately, multicast packets are transmitted at the base rate needlessly, which prevents rich multimedia contents from being delivered to users. To this end, a number of prior studies have proposed to increase multicast capacity whereby an Access Point (AP) transmits at the highest data rate that can be decoded by all subscribers. Another approach is by controlling subscriber-AP associations such that a given objective, e.g., AP load, is met. Moreover, they have also proposed using relays to help boost stations with weak channel condition. In this paper, we …

The Privacy-Value-Control Harmonization For Rfid Adoption In Retail, Ben D. Renegar, K. Michael
The Privacy-Value-Control Harmonization For Rfid Adoption In Retail, Ben D. Renegar, K. Michael
Professor Katina Michael
Privacy concerns have, at least in part, impeded the adoption of radio frequency identification (RFID) in retail. The adoption of other automatic identification (auto-ID) applications shows that consumers often are willing to trade their privacy or their control of personal information against some value afforded by the application. In this paper, the interplay between privacy, value, and control is examined through a literature survey of four auto-ID applications: mobile phone, electronic toll collection, e-passports, and loyalty programs. The consumer value proposition for the use of RFID in retail is investigated through an online survey exploring end-user perceptions. The results of …
