Authors: Wu Heng , Li Yu Yu , Ma Ke Di
Published: October 2015

Under the assumption that product family manufacturer adopts assemble-to-order (ATO) to assemble common component and specific components into two kinds of product belonging to a same product family and being substitutive for each other, a product marketing and components replenishment model is developed. The optimal marketing and replenishment policy for product family ATO manufacturer is obtained. And an algorithm for the optimal policy is proposed. It is shown through theoretical, numerical and empirical analysis that product family ATO producer should make the prices of products no larger than their intrinsic value, and the difference between prices not too big or too small; with the rise of product intrinsic value, producer should raise the prices of whole product family, increase the time with components in stock and shorten the cycle of replenishment.

Authors: Ding Na
Published: October 2015

In the era of rapid growth and high competition, a company must possess an information/knowledge advantage in order to hold the upper hand in the industry. Therefore, the company has to continuously monitor its competitors in order to get enough information and convert the information into competitive knowledge. Although information technology has been used in many areas and has many successful examples, it is rarely the case that information technology was used for the task of competitor intelligence. Accordingly, this study describes the Enterprise Competitive Intelligence System. Competitive Intelligence (CI) is one of the key factors for enterprise risk management and decision support. However, the functions of Competitive Intelligence are often greatly restricted by the lack of sufficient information sources about the competitors. Competitive Intelligenceaims to monitor a firms external environment for information relevant to its decision-making process. The article describes the concept and the functions of the Enterprise Competitive Intelligence System, discusses the principle of its construction, and also discusses the construction process and the awareness of CI.

Authors: Yang Mei , Kang Jian
Published: October 2015

In order to maintain high network QoS (quality of service) against new high-distributed low-rate QoS violation, this paper proposes a novel recognition scheme with the consideration of multiple network features in both macro and micro side. This scheme uses Multi-stream Fused Hidden Markov Model (MF-HMM) in automatic low-rate QoS violation recognition for integrating multi-features simultaneously. The multi-features include the I-I-P triple and TCP header control Flag in a data packet at a micro level, and R feature in network flow at a macro level. In addition, based on the successful experience of Load-Shedding, Kaufman algorithm is used to adjust and upgrade threshold value dynamically. Our experiments show that our approach effectively reduces false-positive rate and false-negative rate. Moreover, it has a high recognition rate specifically for new QoS violation by High-Distributed Low-rate Denial of Service attacks.

Published: October 2015

Age classification based on facial images is attracting wide attention with its broad application to human-computer interaction (HCI). Since human senescence is a tremendously complex process, age classification is still a highly challenging issue. In our study, Local Directional Pattern (LDP) and Gabor wavelet transform were used to extract global and local facial features, respectively, that were fused based on information fusion theory. The Principal Component Analysis (PCA) method was used for dimensionality reduction of the fused features, to obtain a lower-dimensional age characteristic vector. A Support Vector Machine (SVM) multi-class classifier with Error Correcting Output Codes (ECOC) was proposed in the paper. This was aimed at multi-class classification problems, such as age classification. Experiments on a public FG-NET age database proved the efficiency of our method.

Abstract. This paper proposes an incomplete GEI gait recognition method based on Random Forests. There are numerous methods exist for git recognition,but they all lead to high dimensional feature spaces. To address the problem of high dimensional feature space, we propose the use of the Random Forest algorithm to rank features' importance . In order to efficiently search throughout subspaces, we apply a backward feature elimination search strategy.This demonstrate static areas of a GEI also contain useful information.Then, we project the selected feature to a low-dimensional feature subspace via the newly proposed two-dimensional locality preserving projections (2DLPP) method.Asa sequence,we further improve the discriminative power of the extracted features. Experimental results on the CASIA gait database demonstrate the effectiveness of the proposed method.

Published: October 2015

Color space conversion (CSC) is an important kernel in the area of image and video processing applications including video compression. As a matrix math, this operation consumes up to 40% of processing time of a highly optimized decoder. Therefore, techniques which efficiently implement this conversion are desired. Multicore processors provide an opportunity to increase the performance of CSC by exploiting data parallelism. In this paper, we present three novel approaches for efficient implementation of color space conversion suitable for homogeneous and heterogeneous multicore. We compare the performance of color space conversion on a variety of platforms including OpenMP running on homogeneous multicore CPUs, CUDA with NVIDIA GPUs and OpenCL running on both NVIDIA and ATI GPUs.

A Novel Distributed Jointly Sparse Optimization Algorithm
Authors: Wu Di , Jiang Tian Li , Ge Lin Dong , Peng Hua
Published: October 2015

This paper develops a novel distributed jointly sparse optimization algorithm to recover the sparse signal, in which the joint sparse structure is used to improve the quality of recovery. In distributed networked multi-agent system, each agent collects measurement vectors and aims to recover its own sparse signal collaboratively in a distributed manner. We propose to use the factored gradient approach to calculate the solution iteratively, and introduce a energy vector of the current estimates as the consensus constrain which is updated by inexact consensus optimization for its distributed implementation. This algorithm does not require excessive data transmissions from distributed agents to fusion center, which reduces communication overhead and the computational complexity of the agents. Simulation results demonstrate that the proposed distributed algorithm has strong recovery performance and can reach global convergence as well as fast convergence rate.

Authors: Bykov A. , Shardakov I. , Shestakov A.
Published: October 2015

This paper presents the results of experimental and theoretical studies justifying the possibility of using infrared (IR) thermography for detection of deformation debonding of composite material from a reinforced concrete structure that occurs under operating conditions and develops according to the cohesion scenario. The analysis of the results allowed us to determine the optimal inspection parameters of IR thermography to assure best registration of the presence of fiber composite material debonding from the surface of a concrete structure. It has been found that the most accurate and timely information about debonding in a carbon fiber sheet/epoxy/concrete/delamination/concrete system can be obtained during the cooling stage after pulse heating of the structure surface, since at this stage the magnitude of thermal response to debonding reaches its maximum.

Rezultati nakazujejo na pomanjkljivosti na področju statističnih podatkov, kot problem se kaže obravnava dijakov migrantskega ozadja kot dijakov s posebnimi potrebami, spodbudne pa so ugotovitve o dokajšnji senzibilnosti učiteljev in njihovi veliki iznajdljivosti pri iskanju načinov vključevanja dijakov v pouk. Zdi se, da se učitelji in šole trudijo pomagati dijakom po svojih najboljših močeh, pri čemer številne možnosti udejanjanja načela interkulturnosti še zdaleč niso izčrpane. članek se končuje z razčlenjenimi predpostavkami za nadaljnje raziskovanje.

Representative Bureaucracy and Youth Violence in Juvenile Detention Facilities
Authors: Silvera Ginger
Published: October 2015

This exploratory study uses the representative bureaucracy theory to consider the racial representative role, which suggests that administrators who are minorities are more inclined to represent minority interests. This research examined if racial identity and gender was related to detention officers’ perceptions of themselves as advocates for same race and same gender to incarcerated youth and to understand what they perceive are the causes for youth violence. A qualitative study was done on individuals who worked with inmates at the Los Angeles County juvenile detention facilities. The grounded theory approach was used for data analysis by observing common responses among participants. The results of this analysis indicate that detention officers are more likely to pursue the advocate role, especially when officers share the same race and gender to minors.
Characterization of Silane Modified Polyvinyl Acetate Water Based Dispersion Film
Authors: Dubininkas Mindaugas , Buika Gintaras
Published: October 2015

Major advantage of silane-modified systems is possibility to cross link reactive silanol groups and fortify polymer mechanical and chemical properties. However, application of modern analysis techniques and further characterization of macromolecular structure produced is complicated due to a poor solubility of silane modified polymer in various solvents. Silane modified polyvinyl acetate (PVAc) dispersions were produced by classic radical and RAFT polymerization using silane co-monomers and dispersion system stabilizer - silane modified industrial grade polyvinyl alcohol. The present paper deals with confirmation of silanol, siloxane bonds, silicon content and distribution, as well film surface morphology of silane modified PVAc dispersions films.
Mapping the Fit Between Research and Multimedia: A podcast exploration of the place of multimedia within / as scholarship
Authors: Riecken Ted
Published: October 2015

Using the medium of the podcast this piece highlights key factors that may have an impact on how multimedia is used by educational researchers. The author examines the degree of congruence between the prevailing norms of representation in educational research and the norms and processes of multimedia as a way of presenting knowledge and information. The podcast also explores the extent to which multimedia is a usable resource in schools, and whether the skill sets and inquiry processes of educational researchers are compatible with the rip / burn / remix manifestos of multimedia and maker cultures. The author / podcaster concludes that changes in the adoption and use of multimedia within / as scholarship will evolve over time as more and more individuals learn how to produce multimedia content, while at the same time, consumers of educational research are becoming acclimatized to increased diversity in forms of knowledge representation.
Mobile(izing) Educational Research: Historical literacy, m-learning, and technopolitics
Authors: Smith Bryan , Ng-A-Fook Nicholas , Corrigan Julie
Published: October 2015

This research project explored the nexus between historical literacies, digital literacy and m-learning as a praxis of mobilizing technopolitics. To do this, we developed a mobile application for teacher candidates to study the absence of the Indian Residential School system as a complement to history textbooks and other curricular materials. Building on the findings of our SSHRC-funded digital history research project, we sought to engender a “technopolitics” as a form of critical historical literacy. Out of this work, we sought to understand how digital technologies contributed to recent calls to mobilize educational research and more specifically, while working to decolonize existing narratives of Canadian history beyond traditional modes of dissemination.
Peer-Reviewer Round Table Response to Ted Riecken’s Scholarly Podcast, “Mapping the Fit Between Research and Multimedia: A podcast exploration of the place of multimedia within / as scholarship”
Authors: Leggo Carl , Paré Anthony , Riecken Ted
Published: October 2015

Beginning with the question of blind peer review in the shifting landscape of multimedia publishing, and concluding with reflections on knowledge-creation in today’s academic culture, Riecken, Leggo, and Paré respond to Riecken’s podcast-article and reflect on the challenges of multimedia and other non-traditional forms of scholarship for the academy and for scholarly communication. Leggo and Paré were the peer reviewers for Riecken’s article, which is part of this same issue and can be listened to here: http://mje.mcgill.ca/article/view/9061. Since they hail from the same vicinity, they convened an author-peer reviewer round-table discussion on the issues raised in writing and reviewing a multimedia article. We are pleased to share their conversation.
À travers le pare-brise : la création des territoires touristiques au Québec et en Ontario (1920-1945)1
Authors: Lambert Maude-Emmanuelle
Published: October 2015

Cet article lève le voile sur les différentes manières dont, historiquement, le territoire a été perçu, conçu et vécu à travers l’expérience et l’essor de la mobilité. À partir des années 1920, l’automobilité a occupé un rôle central dans la réflexion des acteurs du tourisme et dans la création des territoires touristiques. En comparant l’expérience de deux provinces, le Québec et l’Ontario, par le biais d’une analyse iconographique et discursive des guides touristiques et des récits de voyage, ce texte montre en quoi deux territoires, ayant des caractéristiques biogéophysiques semblables, développent des représentations touristiques différentes en fonction de facteurs culturels.
Reading and Theorizing James Baldwin: A Bibliographic Essay
Authors: Francis Conseula
Published: October 2015

Readers and critics alike, for the past sixty years, generally agree that Baldwin is a
major African-American writer. What they do not agree on is why. Because of his artistic
and intellectual complexity, Baldwin’s work resists easy categorization and Baldwin
scholarship, consequently, spans the critical horizon. This essay provides an overview of
the three major periods of Baldwin scholarship. 1963–73 is a period that begins with the
publication of The Fire Next Time and sees Baldwin grace the cover of Time magazine. This
period ends with Time declaring Baldwin too passé to publish an interview with him and
with critics questioning his relevance. The second period, 1974–87, finds critics
attempting to rehabilitate Baldwin’s reputation and work, especially as scholars begin to
codify the African-American literary canon in anthologies and American universities.
Finally, scholarship in the period after Baldwin’s death takes the opportunity to
challenge common assumptions and silences surrounding Baldwin’s work. Armed with the
methodologies of cultural studies and the critical insights of queer theory, critics set
the stage for the current Baldwin renaissance.
Going to Meet James Baldwin in Provence
Authors: Miller D. Quentin
Published: October 2015

The author travels to St.-Paul-de-Vence, the site of Baldwin’s final decades, with the
intention of understanding expatriation and/or exile more deeply. The intention of this
visit is to fill in some of the gaps in Baldwin’s official biographies, which do not tend
to dwell on his time spent in Provence as much as his time in Paris, Turkey, New York, and
elsewhere. By interviewing a woman who knew Baldwin well during those years, the author
manages to add new layers to his understanding of Baldwin’s late years, but finally
arrives at the understanding that writing (rather than analyzing) is the main goal of the
expatriate writer. Inspired by Baldwin’s muse, he stops contemplating his subject and gets
to work, finally connecting the act of writing to expatriation by doing it.
