Title: Online Advertising and its Security and Privacy Concerns
Authors: Angelia, Davar Pishva
Abstract: Commercial advertising has greatly benefitted from Internet services and online advertising can even be considered as the foundation of web economy. However, despite the availability of many books on how to create, use and make profit from online advertisement; there is little in-depth study on its true nature, security and privacy concerns. Through this research, the authors were able to establish an in-depth understanding of online advertising by collecting and analyzing numerous data on online advertising, with the hope that it could serve as a basis for further study on the field. The authors have also examined the security and privacy concerns of online advertising and the various gimmicks used to victimize innocent people. On the positive side, the paper explains the attractiveness of free online advertising services and the mechanism though which website owners profit from hosting online advertisements despite the fact that neither advertisers nor users pay for the services. On the negative side, the paper shows how online advertising hosts could be victimized by some shroud users for their money making purposes by continuous clicking of online advertisements without any intention of purchase. It also cites cases in which some website owners have marketed users_ private information behind the scene. The paper concludes by highlighting pros and cons of online advertising, Le., despite its numerous advantages, such as efficiency and range, it presents many dangers to advertisers, providers, website owners, and users.

Title: Accelerating E-Commerce Sites in the Cloud
Authors: Wei Hao, James Walden, Chris Trenkamp
Abstract: E-commerce web sites typically have large fluctuations in their IT resource usage, while rapid elasticity is an essential characteristic of cloud computing. These characteristics make the cloud a good fit for hosting e-commerce web sites. Cloud providers deploy their cloud in their data centers. However, cloud providers usually have a limited number of data center locations around the world. Thus, e-commerce web sites in the cloud may be far away from their customers. Long client-perceived response latency may cause e-commerce web sites to lose business. To solve this problem, we propose a virtual proxy solution to reduce the response latency of the e-commerce site in the cloud. In our approach, a virtual proxy platform is designed to cache applications and data of e-commerce sites. A k-means based table partitioning algorithm is designed to select frequently used data from the database in the cloud. We have used an industrial e-commerce benchmark TPC-W to evaluate the performance of our approach. The experimental results show that our approach can significantly reduce the client-perceived response time.

Title: Internet Science: a Manifesto
Author: Kave Salamatian
Abstract: The purpose of this paper is to describe a new emerging science: Internet science. This paper argues that cur-rent Internet is a direct by-product of Shannon’s Information theory and its master thesis. After that I attempt a general and generic definition of a network and discuss the different alternatives. This discussion results in defining a network as asset of distributed actors cooperating for exchanging information. Based on this definition, I describe how cooperation in networks happens at two conceptual levels: on the structure and the growth of the network and on the information exchange (or forwarding). After describing a potential approach to understand the growth of a network as resulting from an iterative prisoner’s dilemma game, I explained how forwarding cooperation can be divided into three classes: full cooperation, selfishness and non-rational cases. This discussion opens a discussion on the need to develop a new economical theory for understanding networks and information exchange.

Title: A Neuromorphic VLSI Grid Cell System
Authors: Tarek M Massoud , Timothy K Horiuchi
Abstract: Neurons in the medial entorhinal cortex of rats have been found to respond in a two-dimensional hexagonal grid pattern anchored to the environment. Grid cells with different spatial frequencies are thought to contribute to the creation of unimodal place cell responses useful for spatial navigation. In this paper we present results from an analog VLSI circuit that generates a hexagonal grid of activity using continuous attractor dynamics and transmits this pattern via neuron-like spikes. This circuit is a component of a larger system for modeling the neural circuits underlying mammalian spatial navigation.

Title: Clinical Information Systems in Private Hospitals
Author: Aini Aman
Abstract: With the tremendous developments in Information Technology (IT), many organizations in private sectors use IT to transform their services and operation. Like any other sectors, the health sector has been benefited from the adoption of IT in transforming their services for society well-being. The applications of IT have greatly improved accessibility, quality and cost-effectiveness of health care. Clinical Information Systems (CIS) are one of the examples of the applications of IT in healthcare. CIS are computer applications that support the operations of clinicians engaged in providing care to patients. However, CIS does not always improve the outcomes and performance of the health professionals, but might bring about negative impacts on their performance and practices. Studies on medical errors have shown that errors in healthcare and medicine are not rare and may bring about severe harm to patients. This paper aims to understand the use of CIS in hospitals and their impact on patient safety. Using interviews with medical practitioners in private hospitals in Malaysia, the findings provide insights for system developers and hospital managers on the usability of CIS to ensure the delivery of better patient care since error reduction is one of the dimensions of health service quality.
