Title: MEASURING THE QUALITY OF ESERVICES AND ITS IMPACT ON STUDENTS

SATISFACTION AT JORDANIAN UNIVERSITIES

Author: HARETH ALSHAMAYLEH, RASHA ALJAAFREH, ALI ALJAAFREH, DARA ALBADAYNEH

Abstract: This research aims at measuring the quality of EServices and its impact on student satisfaction at Jordanian universities. Toward this aim, a research model was developed and tested within the context of Jordanian universities. A questionnaire consisting of 40 (Likert) type items were distributed to a convenience sample of 755 respondents. Primary data were collected from 703 students with a response rate of 90.7%. SPSS package was used to determine if the quality of Eservices dimensions (Website design, reliability, efficiency, responsiveness, ease of use, availability and privacy) has an impact on students� satisfaction. The results show that all of the Eservices dimensions have an impact on students satisfaction expect for the dimension of ease of use. In addition, the researchers present some recommendations for universities to apply eservices quality dimensions through websites, and some suggestions for future research.

Keywords: Students Satisfaction, Electronic Services Quality, Jordanian Universities.

Title: EFFICIENT TECHNIQUES FOR PREDICTING SUPPLIERS CHURN TENDENCY IN E

COMMERCE BASED ON WEBSITE ACCESS DATA

Author: VERONICA S. MOERTINI, NIKO IBRAHIM, LIONOV

Abstract: Electronic supplier relationship management (eSRM) is important in order to maintain strong, long lasting and beneficial relationship between ecommerce firms and their suppliers. One important function of eSRM is to predict suppliers who tend to churn such that early �treatment� can be given. In the ecommerce systems that involve suppliers as the websites users, predicting suppliers� churn tendency can be based on analyzing their frequencies in accessing the ecommerce websites.

Our proposed techniques include data warehouse design (supporting the data collection and preprocessing) and unsupervised algorithms that analyze the preprocessed bitmaps of time series data representing suppliers website access from time to time. Having bitmaps as inputs, our proposed algorithms are efficient (the time complexity is O(n)) as proven with our experiments. In experimenting with real world data of an ecommerce system selling hotel rooms, our techniques produce output of supplier segments where each segment has certain churn level tendency and need specific treatment.

Title: INTENSIVE FIXED CHUNKING (IFC) DEDUPLICATION FOR SPACE OPTIMIZATION IN

PRIVATE CLOUD STORAGE BACKUP

Author: M.SHYAMALA DEVI, V.VIMAL KHANNA, M.SHAHEEN SHAH

Abstract: Cloud Storage provides users with abundant storage space and make user friendly for immediate data access. But there is a lack of analysis on optimizing cloud storage for effective data access. With the development of storage and technology, digital data has occupied more and more space. According to statistics, 60% of digital data is redundant, and the data compression can only eliminate intrafile redundancy. In order to solve these problems, DeDuplication has been proposed. Many organizations have set up private cloud storage with their unused resources for resource utilization. Since private cloud storage has limited amount of hardware resources, they need to optimally utilize the space to hold maximum data. In this paper, we are going to discuss the flaws in the existing deduplication methods and introduce new methods for Data DeDuplication. Our proposed method namely Intensive Fixed Chunking (IFC) Deduplication which is the enhanced File level deduplication that provides dynamic space optimization in private cloud storage backup as well as increase the throughput and de duplication efficiency

Author: DEDY RAHMAN WIJAYA

Abstract: ASEAN Single Window (ASW) implementation ensures compatibility of Member States National Single Windows (NSWs) with international open communication standards while also ensuring that not managed properly. Port Company in Indonesia often ignore linkage analysis between IT investment, business objectives, and business impact. Therefore, the value of IT service not been well defined. This work has raised this issue and try to propose systematic approach for IT Financial Management process based on ITIL best practice standard. Research case study in one of the largest governmentowned port company in Indonesia that implements Port Integrated IT services. This work start with planning, analysis, and design to be produced proposed IT Financial Management process. Business case analysis perform in planning phase to make sure the IT investment related with business objectives and has measurable impact.

Further, minutiaebased matching has difficulty in quickly matching two fingerprint images containing different numbers of unregistered minutiae points. We introduced an enhancement algorithm using Gabor filter based matching to capture both local and global details in a fingerprint as a compact fixedlength Fingercode. The improved filtering used to feather extraction in our proposed algorithm with eight different directions. The last step of our proposed algorithm is fingerprint matching, which is based on

Title: IDFPTREE: AN EFFICIENT TREE FOR INTERACTIVE MINING OF FREQUENT SUBGRAPH

PATTERNS

Author: MOHAMMAD H. NADIMISHAHRAKI, MARYAM TAKI, MOHAMMAD NADERI

Abstract: Recently, knowledge extraction from transactional graph databases by mining frequent subgraph patterns has become an interesting research topic. One of the important challenges in this topic is the situation called interactive mining in which the minimum support threshold can be frequently changed to find proper frequent subgraph patterns. Obviously, running the mining method from scratch is very costly. Therefore, in this paper, an efficient tree called IDFPtree is proposed to develop our previous twolayer model for interactive mining of frequent subgraph patterns from transactional graph databases. The proposed tree constructs the mining model separated from the mining process. Thus, when the minimum support threshold is changed, there is no need to reconstruct the mining model, and only the mining process must be rerun. The experimental results show when the mining model is constructed by IDFPtree, it can be frequently used and the total runtime of interactive mining of frequent subgraph patterns can be reduced.

Abstract: High performance phase frequency detector (PFD) is one of the key modules in high speed delaylocked loop (DLL). The operation of DLL depends on the performance of its detector. The demand for the reduction of power dissipation in CMOS design is a challenge in order to optimize circuit power consumption. A low power dynamic pseudoPMOS PFD is proposed to make DLL system more reliable. In this work NOR gate of typical TSPC PFD is replaced with a low power dissipation pseudo PMOS AND gate built of 3 PMOS transistors. PseudoPMOS AND integrated into proposed TSPC PFD to run maximum frequency at 1G Hz with 1.8 V input power supply. This proposed PFD has been implemented in Mentor Graphics 0.18 μm CMOS process technology and consumed 163.36 �m2 active layout area with 206 nW total power dissipation will further trim down the total cost of the DLL.
