3. STABLE CLUSTER MAINTENANCE SCHEME FOR BEE-ADHOC- C: AN ENERGY-EFFICIENT AND SCALABLE MULTIPATH ROUTING PROTOCOL FOR MANET

Authors: M.SIDDAPPA , SASMITA MOHAPATRA

Abstract: Mobile ad hoc network (MANET) is one of the most important and unique network in wireless network which has brought maximum mobility and scalability. High efficient routing is an important issue in the design of limited energy resource MANETs. Many research work have been conducted by the researchers in the field of routing protocols for MANETs for making it energy efficient as the nodes are with limited resources in terms of battery supplied energy, storage and processing capability. In this paper we have proposed a new technique of routing protocol which utilizes the concept of swarm intelligence in which bee inspired routing is chosen as the ultimate routing protocol for energy efficient MANETs. To make the system more energy efficient we have chosen the clustered based approach as Bee-AdHoc-C. Bee-AdHoc-C is an evolution from Bee-AdHoc which is a bee inspired routing protocol for MANETs. This method provides parallel routing by which it reduces the overhead and improves the scalabi

Authors: ABOUL ELLA HASSANIEN , ESSAM SHAABAN

Abstract: Churn prediction is considered a big issue in the Telecom market because customer acquisition costs five to eight times than retaining an existing one. Customer retention is the action that a service provider undertakes in order to reduce customer dissatisfaction and decrease the probability of leaving a service provider. This paper proposes a churn prediction retention framework based on data mining techniques. Deploying the proposed framework into a business intelligence system can help in enhancing the efficiency of customer relationship management. Moreover it can help customer churn management department to easily predict and retain the expected future churners in many business areas. The proposed framework mainly composed of seven phases and sub-phases. A case study is demonstrated to evaluate the framework throughout 5000 customers’ records in an anonymous telecom company.

7. POTENTIAL GAME FRAMEWORK FOR INTERFERENCE AVOIDANCE IN CRAHNS USING WAVEFORM ADAPTATION AND SUB- CARRIER ALLOCATION

Authors: HASAN MAHMOOD , QURRATULAIN MINHAS , SUNDUS NASEER

Abstract: The simultaneous transmissions of multiple users on a channel interfere with each other and it becomes pivotal to devise a mechanism to obtain some form of separation. In a cognitive radio ad hoc network (CRAHN), the users compete to acquire best suitable bandwidth from already scarce spectrum, resulting in a fierce competition. The nodes may not observe desirable etiquettes in selecting channels and waveforms that result in chaos, which degrades the Quality of Service for the entire network. In order to inhibit the nodes while maintaining their autonomous behavior, there is a need of intelligent mechanism to inculcate the nodes in the network. A game theoretic framework is proposed to achieve convergence in selecting sub-channels and waveforms for transmissions. The proposed model is an eigen-iterative framework, in which signature sequences and sub-channels keep on updating after every cycle. Eigenvectors corresponding to the minimum eigenvalue of correlation matrix is used to maximi

9. NUMERICAL INVESTIGATION OF PACKED-BED THERMAL ENERGY STORAGE SYSTEMS WITH PREDICTION-BASED ADJUSTMENT OF THE HEAT TRANSFER FLUID FLO

Authors: ALESSANDRO PISANO , ANTONELLO BACCOLI , DANIELA DEJACO , ELIO USAI , FABIO SERRA , GIORGIO CAU , MARTIN HORN , PIERPAOLO PUDDU\

Abstract: This paper numerically investigates ad-hoc charging strategies for a Packed Bed Thermal Energy Storage System. We derive a mathematical model of the system, whose reliability is assessed through comparison with experimental measurements taken on a laboratory-scale prototype with the packed bed made of alumina particles and air being used as the heat transfer media. Then we show by numerical investigations that certain non-constant flow profiles, which are determined on the basis of a predictive mechanism, yield a more effective use of the considered sensible heat storage apparatus in comparison to the commonly adopted constant-flow charging/discharging process.

10. REGION OF INTEREST VIDEO CODING FOR ULTRASOUND IMAGERY

Authors: BRIAN C.S. LOH , PATRICK H.H. THEN

Abstract: Echocardiograms are the result of utilizing ultrasound devices to capture cardiac structures and dynamics. The results of these scans, which are depicted as video or images, are assessed by physicians to determine heart conditions. Although ultrasound devices are making way into diverse medical scenarios, their utility has been hampered by the need for extensive operator training to perform examinations, and medical experience required for analysing imagery. Telesonography or tele-ultrasound, allows for the guidance and interpretation of ultrasound acquisitions by distant medical experts. Since video content sharing necessitates large amounts of bandwidth, encoding techniques can be applied beforehand to reduce the size of exchanged data. This paper introduces a healthcare solution that aims to support the encoding and compression of medical imagery. The proposed application combines several image processing techniques with ROI video coding algorithms to achieve optimal size and qualit

12. A MAC PERFORMANCE OF MOBILE AD-HOC 802.11AC LAN OVER CORRELATED FADING CHANNEL

Authors: HA CHEOL LEE

Abstract: FER (Frame Error Rate) and MAC (Medium Access Control) throughput are derived over error-prone channel in the IEEE 802.11ac mobile ad-hoc LAN. In this paper, DCF (Distributed Coordination Function) protocol and A-MPDU (MAC Protocol Data Unit Aggregation) scheme are used to evaluate the MAC throughput. Using theoretical analysis method, A MAC saturation throughput is evaluated according to the mobile speed and the number of frames in each A-MPDU on the condition that the number of station, frame payload size, transmission probability, the number of parallel beams and fading margin are variables. When the mobile speed is typically 1 m/sec and the number of aggregated MPDUs in each A-MPDU is 100, it is identified that the MAC layer throughput of IEEE 802.11ac can be maximally attained up to a 97.2% of physical transmission rate in this evaluation.

13. A WEB-BASED DECISION SUPPORT SYSTEM FOR USED-CAR PRICING

Authors: AYHAN DEMIRIZ

Abstract: Used-car trade has a significant portion in overall automobile market and determining the values of the cars is an important problem. This study proposes a new methodology for determining the market value of the used-cars by observing the classifieds in an e-commerce site. This type of data acquisition plays an important role to build pricing models and to conduct further analysis in our approach. In data acquisition stage, a set of new listings are chosen randomly each day from an ecommerce site (a web site like Craigslist), then these listings are observed until a pre-determined period (e.g. thirty days) or delisting time, whichever comes first. The crucial part of our approach is the assumption of a sale event when the listing is no longer available i.e. delisted from the e-commerce site. The proposed methodology may potentially be used for pricing any used item based on the web listings. A web site was developed to help clients/users for determining the market values of their cars

Authors: M. S. H. CHOWDHURY , MD. ALAL HOSEN , S. M. A. MOTAKABBER

Abstract: The aim of this paper is to use high-order harmonic balance method (HBM) as a novel solution procedure for investigation of the Duffing-relativistic oscillation. Usually, a set of complex nonlinear algebraic equations is appeared when HBM is applied. Investigating analytically for such kind of complex nonlinear algebraic equations is tremendously difficult and cumbersome. In the present study, a small parameter is found, for which the power series solutions produces desired results. The obtained results are evaluated by comparing with the exact solutions computed numerically. The effect of initial conditions in the nonlinear natural frequencies is carried out and it is proved the proposed method is not only simple, but also more reliable for analysis for the Duffingrelativistic oscillator. The method is mainly illustrated in strongly nonlinear Duffing-relativistic oscillator, but it can be widely applicable in other problems arising nonlinear sciences and engineering.

Abstract: Digital image watermarking is a branch of information hiding in which the ownership information will be hidden in the cover image. Performing digital image watermarking, some important issues such as imperceptibility, robustness, capacity and security should be considered. The strength and weakness of each of these issues depends on the watermark algorithm and also the domain in which the watermark has been hidden.

Abstract: PID controllers have been successfully used in versatile applications, especially with the aid of available mature tuning methods such as the Ziegler-Nichols method. Recently, fractional order PID controllers were proposed after a series of researches on fractional calculus. It is intriguing for the flexibility of the adoption of fractional order which is free from the limit of integer order. This paper studied the fractional order PID controller of different fraction order applied in a DC motor system. The simulation results show that the fractional order PID controllers are promising compared to the integer PID controllers.
