Kerentanan yang Dapat Terjadi di Jaringan Komputer pada Umumnya

The rapid development of computer technology allows ease of access, yet lurking threats. Security in computer networks are categorized into two, namely the physical and non physical security. Physical security is a security that is more likely to focus to all things physical. This type of security can be avoided by more careful guarding of the thieves’ threats by putting in locked places and so on. As with the non-physical security, the more important issue involved is such as data security where its physical value may be less important. Therefore, this article discussed the safety factor especially on a computer network, vulnerable points on the computer network, techniques often used on attacks and some things you can do to ward off them.
Exploration Through Visual Art: Ego-Identity Development Among Hispanic American Adolescents

Dr. Hyeyong Bang, Advisor Community-based art practices connect the artist with the community, promoting an awakened society of people, capable of creating aesthetically pleasing artwork as well as positive social change (Congdon, 2004). The purpose of this case study was to explore how the environment and identity-themed visual art projects influence the ego-identity development of Hispanic American adolescents. Nine adolescents (between 12-14 years old) who were enrolled in a community-based art program participated in this study. The findings of this study indicates that this community-based art program and identity-themed projects provided the Hispanic American youth in this study with artistic competencies, which lead to the ability to express their uniqueness and to develop coping mechanisms through art. Along with this, the Hispanic American youth in this study articulated an increase in self-esteem, due in large part to the afforded recognition felt within the community. In addition, a sense of affiliation and support, coming mostly from their peers and the staff and volunteers at the program, enriched the creative growth and provided the necessary encouragement for positive youth development.
Introducing OAWAL: Crowdsourcing best practices for open access workflows in academic libraries

At is point, the team has developed significant areas of focus for workflow management and will be building upon the current structure as informed through in-person and online crowdsourcing. The current sections to be developed are: advocacy, Creative Commons, the Library as Publisher, standards, workflows, and discoverability. each section will be rolled out to social media via tumblr, twitter, & Facebook seeking feedback and in addition, we'd like to obtain feedback from in-person sessions at conferences such as this one.
Feature weighting approaches in sentiment analysis of short text

In this thesis, we propose a supervised classi cation scheme based on computation of the statistical scores for the textual features. More speci cally, we consider binary classi cation (opinionated or factual, positive or negative) of the short text in the domains of movie reviews and newspaper articles. We analyze the performance of the proposed models on the corpora with the unequal sizes of the training categories. Based on our participation in di erent evaluation campaigns, we analyze advantages and disadvantages of the classi cation schemes that use Z scores for the purpose of classifying a sentence into more than two categories, e.g. positive, negative, neutral and factual. As a new feature weighting measure, we give an adaptation of the calculation of the Kullback-Leibler divergence score, called KL score. Considering the performance of di erent weighting measures on training corpora with unequal sizes, we chose two best performing scores, Z score and KL score. Thus, we propose a new classi cation model based on the calculation of normalized Z score and KL score for the features per each classi cation category. One of the advantages of this model is its exibility to incorporate external scores, for example, from sentiment dictionaries. The experiments on datasets in Chinese and Japanese show a comparable level of performance of the proposed scheme with the results obtained on the English datasets without any use of natural language speci c techniques. The advantage of the approaches analyzed in this thesis is that they can work as quick and easily interpretable baselines for short text classi cation.

Simulation Performance of Multiple-Input Multiple-Output Systems Employing Single-Carrier Modulation and Orthogonal Frequency Division Multiplexing

Abstract : This thesis investigates the simulation performance of multiple-input multiple-output (MIMO) systems utilizing Alamouti-based space-time block coding (STBC) technique. The MIMO communication systems using STBC technique employing both single-carrier modulation and orthogonal frequency division multiplexing (OFDM) are simulated in Matlab. The physical layer part of the IEEE 802.16a standard is used in constructing the simulated OFDM schemes. Stanford University Interim (SUI) channel models are selected for the wireless channel in the simulation process. The performance results of the simulated MIMO systems are compared to those of conventional single antenna systems.
Extending the Wizard of Oz Methodologie for Multimodal Language-enabled Systems

In this paper we present a proposal for extending the standard Wizard of Oz experimental methodology to language-enabled multimodal systems. We first discuss how Wizard of Oz experiments involving multimodal systems differ from those involving voice-only systems. We then go on to discuss the Extended Wizard of Oz methodology and the Wizard of Oz testing environment and protocol that we have developed. We then describe an example of applying this methodology to Archivus, a multimodal system for multimedia meeting retrieval and browsing. We focus in particular on the tools that the wizards would need to successfully and efficiently perform their tasks in a multimodal context. We conclude with some general comments about which questions need to be addressed when developing and using the Wizard of Oz methodology for testing multimodal systems.
Quality Evaluations and algorithmic Improvement of the next Generation Video Coding - HEVC

The increased processing power and screen sizes of mobile devices has made it desirable to watch multimedia presentations on the go. On such devices the data network bandwidth is usually the limiting factor, which imposes a tradeoff between quality and resolution on the presented content. A new video compression system called High Efficiency Video Coding (HEVC) is currently under development. The vision of HEVC is to create a compression system that achieves the same quality at half the bit rate compared to the existing H.264/AVC standard [2]. The goal of this thesis is to investigate how HEVC performs compared to H.264/AVC using mobile platforms and sport content as the scenario. The subjective test was conducted on an Apple iPad. It indicated that HEVC has a clear gain in compression compared to H.264/AVC. On average at a resolution of 640x368, HEVC achieved a good quality rating at approximately 550 kilobit per second while H.264/AVC did almost reach this quality at 1000 kilobit per second. However, it was shown that subjective quality gain varied over content. The objective measurements showed an overall reduction in bit rate of 32% for the luma component. However, the reduction of bit rate was highly variable over content and resolution. A high correlation between the subjective and objective measurements was found, which indicates that it was almost a linear relationship between the reported subjective and objective results. In addition, a proposed deblocking filter was implemented. The filter applies a new filter function of the luma samples and performs line based filtering decision. On average the reduction in bit rate was reported to be 0.4%, with a maximum reduction of 0.8% for the luma component. The decoding time relative to the second version of the HEVC test model was reported to be 1.5% higher. This is most likely due to the line based filtering decision. The general impression of HEVC is that it has the ability to reach the stated vision, and perhaps even surpass, when finalized.
CastGate: An auto-tunneling architecture for IP Multicast

CastGate: an auto-tunneling architecture for IP Multicast <draft-liefooghe-castgate-01.txt> Status of this Memo This document is an Internet-Draft and is in full conformance with all provisions of Section 10 of RFC 2026 [1]. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress. " The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [2]. Abstract The architecture described in this document aims at giving as many unicast-only end-users access to IP multicast content, this without the need for their ISPs to upgrade their network infrastructure to IP multicast. It further does not require any change to the unicast only infrastructure nor to the end-user operating systems. The access that is provided, is from a user's perspective as good as a real IP multicast connection. It can be used to send and receive ASM as well as SSM content. It further allows applying Authentication, Authorization and Accounting (AAA) to IP Multicast. 1 Introduction The deployment of IP multicast is not going as fast as the multicast community would want. The major reason for this is that we are in some sort of twofold deadlock situation with problems situated at three parties: The first party involved is the ISPs. As described by Diot C. et al. [3], ISPs are reluctant to deploy IP multicast because it relies on a protocol architecture that requires more setup and administration than the unicast architecture. This makes that in order for a multicast solution to be cost efficient one will need potentially a large number of multicast capable customers.

Knowledge Construction in Concept Design: Case Studies

This paper proposes a framework to understand the influence of design methods on creativity. Our proposal is based on a cognitive theory of design as a knowledge generation process. We track the construction of knowledge trough research, decision making, and construction activities in the development of new concepts. We present two case studies involving different techniques to exemplify this approach. We believe knowledge construction can lead us a cognitive theory of creativity in design useful for assessing practices as well.
3 - Segmentation d'images couleur par coalescence non supervisée d'histogrammes 2D et fusion de régions selon la théorie de Dempster-Shafer

Dans cet article nous proposons une methode de segmentation d'images couleur selon une nouvelle approche que nous appelons bi-marginale. Afin de pallier les defauts des approches marginales classiques, nous considerons les composantes couleur deux a deux afin d'avoir une vue partielle de leur correlation. Travaillant selon cette vision bi-composante, nous considerons les trois combinaisons possible comme trois sources d'informations independantes. Chaque information bi-composante est tout d'abord analysee selon un schema de coalescence morphologique non supervise qui recherche les couleurs dominantes d'un histogramme bidimensionnel. Cela permet de construire trois cartes de segmentation distinctes qui sont combinees par intersection apres avoir ete simplifiees. L'intersection produisant une sur-segmentation, une fusion des regions deux a deux est operee selon un critere de similarite et selon la combinaison de Dempster-Shafer jusqu'a un critere de terminaison. Afin d'automatiser la methode de segmentation, une mesure d'energie est proposee afin de quantifier la qualite d'une segmentation, celle-ci sert tout au long de la methode proposee comme indicateur de performance de la segmentation afin d'en regler les differents parametres.
David Bowie's Influence on JoJo's Bizarre Adventure

This article analyses the influence of David Bowie’s work in JoJo’s Bizarre Adventure, a manga known for its wealth of references to western popular culture. It is argued that David Bowie’s cultural reception can be attested via the presence of three narrative themes featuring in this manga series. The first theme is the exploration of diverse genres and an innovative, genre-defying attitude. The second theme is the use of avant-garde, flamboyant and gender-ambiguous aesthetics for its fictional characters. The third theme is a self-reflexive approach to the creation of fictional characters, intended as an awareness of the temporary, transient nature of their role as reluctant heroes in their own stories.
Adaptive Embedded Systems

Modern embedded systems are evolving in the direction of increased adaptivity and complexity. It is extremely important for a system with limited resource to be adaptive in order to maximize its efficiency of resource usage while guaranteeing a high level of fault tolerance and QoS. This report aims at exploring such a kind of system, i.e. Adaptive Embedded System (AES), which is featured by dynamic reconfiguration at runtime. Based on the investigation and analysis of a variety of case studies related with AES, we proposed the conceptual view and overall architecture of an AES by highlighting its predominant characteristics. We also made an incomplete but detailed summary of the most popular techniques that can be used to realize adaptivity. Those techniques are categorized into dynamic CPU/network resource re-allocation and adaptive fault tolerance. A majority of adaptive applications resort to one or more of those techniques. Besides, there is a separate discussion on dynamic reconfiguration and mode switch for AES. Finally, we classify adaptivity into different modeling problems at a higher abstraction level and build UPPAAL models for two different AESs, a smart phone and an object-tracking robot. Our UPPAAL models provide clear demonstration on how a typical AES works.
Multi-Hop Cellular Radio Network Integrating Frequency and Time Duplexing

The system concept developed by the Wireless World Initiative New Radio (WINNER) project, as part of the Information Society Technologies (IST) Sixth Framework Programme (FP6) of the European Union, as well as other future Orthogonal Frequency Division Multiple Access (OFDMA) based cellular mobile radio networks of the International Mobile Telecommunications (IMT)-Advanced system family, are planned with both Time Division Duplex (TDD) and Frequency Division Duplex (FDD), both as full-duplex and half-duplex transmission in mind. In general both schemes have their benefits and drawbacks. However, both schemes are more or less appropriate under consideration of the communication environment. In metropolitan area scenarios with relatively small radio cells TDD is appropriate. For wide area cells FDD is preferred in general. In future, data services will require ubiquitous mobile radio systems and demand support of an agreed Quality of Service (QoS) in terms of high data rate and low delay. A promising concept for future mobile radio communication systems is the ability to adapt to various deployment strategies by using different radio access technologies, so-called modes. The concept of modes provides customised solutions for specific environments and thus allows the adaptation to various scenarios by selecting the most adequate one. Fixed decode-andforward layer-2 relays are integral part of WINNER and will also be integral part of the next generation of mobile radio networks, namely IMT-Advanced systems. The application of layer-2 relays serves to optimise the cell capacity in a given area, cover otherwise shadowed areas and reduce the network deployment cost, substantially. This thesis introduces a concept for a layer-2 protocol supporting the integration of the two duplex schemes TDD and FDD, operating both full-duplex (fdx) and half-duplex (hdx) links, integrated as modes into one single Data Link Layer (DLL) protocol. Necessary functions for the realisation of coexistence and cooperation of modes are described in detail. The introduced concept furthermore supports the integration of decode-and-forward layer-2 relays including a detailed description of handover signalling in Relay-Enhanced Cells (RECs). By means of stochastic event-driven simulation of mode-handover in RECs, a proof-of-concept for the relay capable multi-mode DLL pro-
Research on vocabulary sizes and codebook universality

Codebook is an effective image representation method. By clustering in local image descriptors, a codebook is shown to be a distinctive image feature and widely applied in object classification. In almost all existing works on codebooks, the building of the visual vocabulary follows a basic routine, that is, extracting local image descriptors and clustering with a user-designated number of clusters. The problem with this routine lies in that building a codebook for each single dataset is not efficient. In order to deal with this problem, we investigate the influence of vocabulary sizes on classification performance and vocabulary universality with the kNN classifier. Experimental results indicate that, under the condition that the vocabulary size is large enough, the vocabularies built from different datasets are exchangeable and universal.
Proximity displays for access control

Managing access to shared digital information, such as photographs and documents. is difficult for end users who are accumulating an increasingly large and diverse collection of data that they want to share with others. Current policy-management solutions require a user to proactively seek out and open a separate policy-management interface when she wants to review or change her access-control policy. However, end users treat access control as a secondary task, and rarely visit a website for the primary task of managing security. Historically, security administrators and auditors were available to check for access-control issues on behalf of users, but in the age of Facebook and Flickr people are responsible for their own content. Users need a way to review their access-control policies that fits into their normal workflows. This thesis proposes the use of proximity information displays — small interface components spatially located near the data elements (or near a representation of data, e.g., file name in a file manager or thumbnail photo in a photo album) that contain information about who currently has access or who could access the data. These displays are intended to help users become more aware of how their data has been used in the past and how the data could be used in the future. We present empirical studies that test the hypothesis: Users of a system that includes proximity information displays of access control-information will implement policies that result in grant/deny actions that better match their preferences than will users of a system where access-control information is available only on a secondary interface. The focus of this thesis is understanding the impact of proximity displays on people's permission-modification behavior. The displays were conceptualized based on interviews with end users and security administrators, which highlighted the need for increased end-user awareness of their policies. Focus groups showed that people liked the idea of showing permission information in proximity to data. Finally, several evaluation studies were conducted in the lab and online using a photo-sharing website. Participants who saw proximity displays that were more comprehensive and could be glanced at easily were better able to identify access-control policy errors. Participants who saw displays that were overly coarse-grained, on the sidebar, or showed information about who had previously viewed the photos, showed no improvement over those who saw permission settings only on a secondary interface. Our studies suggest that proximity displays for access control can help significantly the majority of users who do not normally check their access-control policies.
