This paper presents a general-purpose software framework dedicated to the evolutionary transportation scheduling, which is one of the most challenging areas in transportation engineering. Against evolution, the most popular approach is manual process. Manual process in here is to describe the system business using the most appropriate modeling language(s) at the most appropriate level(s) of abstraction. To demonstrate the applicability of the framework, we report our experience in using the software to generate pavement maintenance report under manual business model.

In today's society, information security and hiding is a key mechanism to protecting one's identity. Image morphing can hide a secret image in a morphed image using a second, reference image. One of the primary methods to make the morphing based information hiding technology practically useful is interactive evolutionary algorithm (IEA). When using IEA, however, the user who is rating the images for their naturalness must rate a large amount of images. During this period of time, it is possible for the user to subconsciously shift the rating criteria, thus skewing the results of the algorithm. To help solve this problem, we propose a k-nearest neighbor (k-NN) reminder, which analyzes the user's previous inputs and creates an estimated fitness rating for images to aid the user in grounding his or her ratings. We ran experiments testing the differences in using the IEA with and without the k-NN reminder, looking to see what impact the algorithm had on the speed of the analysis and the ease of the user's rating ability. Results show that in many instances, the k-NN makes it easier for the user to maintain a standard criterion for the rating of images, with no noticeable impact on the speed of the process.

This paper uses a 2D systems setting, based on the control theory for repetitive processes, to design an iterative learning control law with particular emphasis on the commonly encountered problem of maintaining a specified rotational speed of shaft where disturbances introduce irregularities in the speed achieved. The two motors system is a model for this problem and is used as the basis for a simulation study of the performance of the final design.

We study the asymptotic networking-theoretic multicast capacity bounds for random extended networks (REN) under Gaussian channel model, in which all wireless nodes are individually power-constrained. During the transmission, the power decays along path with attenuation exponent α >; 2. In REN, n nodes are randomly distributed in the square region of side length √n. There are n s randomly and independently chosen multicast sessions. Each multicast session has n d + 1 randomly chosen terminals, including one source and n d destinations. By effectively combining two types of routing and scheduling strategies, we analyze the asymptotic achievable throughput for all n s = ω(1) and nd. As a special case of our results, we show that for n s = Θ(n), the per-session multicast capacity for REN is of order Θ(1/√n d n) when nd = O(n/(log n) a+1 ) and is of order Θ(1/n d · (log n) -n/2 ) when n d = Ω(n/log n).

In this work, we address the problem of finding experts using chains of social referrals and profile matching with only local information in online social networks. By assuming that users are selfish, rational, and have privately known cost of participating in the referrals, we design a novel truthful efficient mechanism in which an expert-finding query will be relayed by intermediate users. When receiving a referral request, a participant will locally choose among her neighbors some user to relay the request. In our mechanism, several closely coupled methods are carefully designed to improve the search performance, including, profile matching, social acquaintance prediction, score function for locally choosing relay neighbors, and budget estimation. We conduct extensive experiments on several datasets of online social networks. The extensive study of our mechanism shows that the success rate of our mechanism is about 90% in finding closely matched experts using only local search and limited budget, which significantly improves the previously best rate 20%. The overall cost of finding an expert by our truthful mechanism is about 20% of the untruthful method and only about 2% of the method that always selects high-degree neighbors. The median length of social referral chains is 6 using our localized search decision, which surprisingly matches the well-known small-world phenomenon of global social structures.

A large portion of energy-aware routing protocol for wireless sensor networks are cluster-based. In cluster based approaches, power of the cluster head (CH) nodes are drained more rapidly compared to other member nodes. Dynamic CH approach could partially alleviate this problem. But even with dynamic CH approach, energy is not uniformly dissipated among all nodes. In this paper, we propose a new energy-aware routing protocol where the communication protocol is such that, even when the clusters are fixed, power dissipation is same over all nodes (except CHs). Every node co-operates with each other to carry the payload to the CH so as the power dissipation is uniform. Therefore reconfiguration of cluster is not necessary, thereby saving a huge signalling cost and interruption in service. Simulation results show that the proposed protocol has longer node lifetime and better distribution of energy dissipation than the original LEACH protocol.

With detailed analysis of 3DS inner data structure, an effective parsing and accessing process is adopted to get necessary data set for 3D scenes reconstruction. Then this data set is stored in self-defined reasonable data structure with high-efficiency access. Based on data set and coordinate conversion of viewpoint from 2D to 3D, a feasible and effective 3D reconstruction process is put forward. Moreover, we used OpenGL's selection mechanism to realize interactive operations of 3D objects with mouse moving or keyboard pressing. Under framework of OpenGL and MFC, Dalian Nationalities University 3D walkthrough system is given as an example to validate effectiveness and efficiency of the proposed 3D scenes reconstruction method. This method not only utilizes quick modeling capability of 3D modeling software, but also makes full use of powerful human-computer interaction capability of OpenGL, and thus gets satisfactory performance of 3D scenes reconstruction. © 2012 ICIC International.

The advance of the Internet in the past decade has radically changed the way people communicate and collaborate with each other. Physical distance is no more a barrier in online social networks, but cultural differences (at the individual, community, as well as societal levels) still govern human-human interactions and must be considered and leveraged in the online world. The rapid deployment of high-speed Internet allows humans to interact using a rich set of multimedia data such as texts, pictures, and videos. This position paper proposes to define a new research area called ‘connected multimedia’, which is the study of a collection of research issues of the super-area social media that receive little attention in the literature. By connected multimedia, we mean the study of the social and technical interactions among users, multimedia data, and devices across cultures and explicitly exploiting the cultural differences. We justify why it is necessary to bring attention to this new research area and what benefits of this new research area may bring to the broader scientific research community and the humanity.

Fault detection on the software implementation of CLEFIA lightweight cipher

Journal of Networks 2012年第8期7卷 1288-1294页

作者： Li, Wei Gu, Dawu Xia, Xiaoling Liu, Ya Liu, Zhiqiang School of Computer Science and Technology Donghua University Shanghai China Shanghai Key Laboratory of Integrate Administration Technologies for Information Security Shanghai China State Key Laboratory of Information Security Institute of Software Chinese Academy of Sciences Beijing China Department of Computer Science and Engineering Shanghai Jiao Tong University Shanghai China

CLEFIA is an efficient lightweight cipher that delivers advanced copyright protection and authentication in computer networks. It is also applied in the secure protocol for transmission including SSL and TLS. Since it was proposed in 2007, some work about its security against differential fault analysis has been devoted to reducing the number of faults and to improving the time complexity of this attack. This attack is very efficient when a single fault is injected into the last several rounds of the CLEFIA, and it allows to recover the whole secret key. Thus, it is an open question whether detecting the faults injected into the CLEFIA with low overhead of space and time tolerance. In this paper, we present a fault detection of the CLEFIA block cipher in the single-byte fault model. Our result in this study could detect the faults with negligible cost when faults are even injected into the last four rounds. © 2012 ACADEMY PUBLISHER.
