Time series classification using MACD-histogram-based recurrence plot

Time series classification is one of the most active research topics in time series data mining, because it covers a broad range of applications in many different domains. Representation for time series is a technique that converts time series to feature vectors representing the characteristics of time series. The performance of classifying time series depends on this representation. Chaotic time series analyses have been well-studied. Moreover, recurrence plotting underlying chaos theory is one of the most robust representation for time series. In this study, we propose a new time series representation utilising the recurrence plot technique. Moving average convergence divergence (MACD) histogram is the acceleration of time that can represent local-variation in time series. Therefore, a recurrence plot that is made from MACD histogram, which is called a MACD-histogram-based recurrence plot (MHRP), can handle time series very well. Recurrence plots are referred to as grey-scale images and we utilise stacked auto-encoders as a classifier for MHRPs. To evaluate the performance of the proposed classifier, experiments using the UCR time series classification archive was conducted. The experimental results showed that the proposed classifier outperforms other methods.
Be a man or become a nurse: Comparing gender discrimination by employers across a wide variety of professions

We investigate gender discrimination and its variation between firms, occupations, and industries with a factorial survey design (vignette study) for a large sample of German firms. Short CVs of fictitious applicants are presented to human resource managers who indicate the likelihood of the applicants being invited to the next step of the hiring process. We observe that women are evaluated worse than men on average, controlling for all other attributes of the CV, i.e., school grades, age, information about activities since leaving school, parents' occupations etc. Discrimination against women varies across industries and occupations, and is strongest for occupations with lower educational requirements and of lower occupational status. Women receive worse evaluations when applying for male-dominated occupations. Overall, the share of women in an occupation explains more of the difference in evaluations than any other occupation- or firm-related variable.
Design of the Key Signal Processing Modules in a Linear CCD Camera

This paper presents an optimization solution on the analog signal generating, sampling and output modules in the signal processing unit of a linear CCD camera. An integrated driver chip is used to increase the drive current of the CCD sensor timing signal, which meets the driving requirements of the horizontal signal. A precise delay circuit is implemented which can adjust the Correlation Double Sampling (CDS) location dynamically and in real time, so that the analog image signal can be always sampled at the best location. To solve the three-color separation problem after sampling and to meet the requirement of the real-time image, the paper designs a resource optimal solution by using only one SDRAM and 25 percent of the FPGA resources to achieve spatial correction. The results show that driven by the timing signal, the output analog image of the CCD sensor is of high quality. The precision of the precise delay circuit is 0.13 ns and the delay is real-time adjustable. In the maximum line rate (9.2 KHz) mode, the output of the imaging system does not have three-color separation. This design is applicable to other imaging systems.

An Algorithm of 3D Mesh Reconstructing Based on the Rendering Pipeline

During the using of 3D mesh, the different LOD meshes are needed for a same model. This paper presents an algorithm of 3D mesh reconstructing based on the rendering pipeline. This algorithm bases the pipeline, performs the coordinate transform and records the original coordinates of the mesh during the vertex shader. It interpolates the vertex's 3D coordinates of every pixel in the rasterization. During the pixel shader, it extracts the visible pixels through the depth testing, and then outputs the corresponding 3D coordinates. According to the relative position between the pixels, it connects the 3D vertices together to make a triangle mesh for the current view. The result LOD mesh can be obtained by merging these triangle meshes for different views. The experiments show that the algorithm is effective, speedy and convenient for adjusting the LOD.
Council of Australian State Libraries (CASL) working group on stack management

Abstract Collection storage and access in libraries with large and complex collections require high level planning and support at the senior management level. A key issue is positioning the collection storage program appropriately within the scope of library wide management to ensure effective support and budgeting. A review of a library's current collection storage and access situation is a good starting point for the development of a long-term storage plan. The review should consider factors such as collection development policy; statutory responsibilities, for example, Legal Deposit; historical arrangements and cataloguing practices; access and preservation requirements of different categories of the collection; and especially, the range of formats to be stored.

Analysis of the Word-Initial Segment with Reference to Lemmatising Zulu Nasal Nouns

The process of lemmatising nasal nouns in the Zulu lexicon is problematic. The traditional method is to lemmatise a Zulu lexical noun by etymological noun-stem. This practice creates difficulties in harmonising lexical nouns with their syntactic application. Most authors and dictionary-makers are inconsistent in identifying the word-initial segment which determines the letter of the alphabet under which the lexical noun should be included. Consequently, dictionary users do not find Zulu dictionaries user-friendly. This article therefore proposes the principle of "a noun without initial vowel" as a method for lemmatising Zulu nasal nouns. It concludes that it is not necessary to delve into the derivational history of a lexical noun, but rather to focus on the product of the operation of morphophonological rules. The article also suggests the need to identify the distinctiveness of the segments of a syllable and to acknowledge that identical forms of a segment do occur at different segmental positions (initial, medial and final). Finally it is argued that the Zulu nasal noun class prefix is constructed according to an open syllable pattern defined by a general CV-formula based on a VCV noun prefix open syllable pattern.

Search over Encrypted Data in Cloud Computing

Cloud computing which provides computation and storage resources in a pay-per-usage manner has emerged as the most popular computation model nowadays. Under the new paradigm, users are able to request computation resources dynamically in real-time to accommodate their workload requirements. The exible resource allocation feature endows cloud computing services with the capability to o er a ordable and e cient computation services. However, moving data and applications into the cloud exposes a privacy leakage risk of the user data. As the growing awareness of data privacy, more and more users begin to choose proactive protection for their data in the cloud through data encryption. One major problem of data encryption is that it hinders many necessary data utilization functions since most of the functions cannot be directly applied to the encrypted data. The problem could potentially jeopardize the popularity of the cloud computing, therefore, achieving e cient data utilization over encrypted data while preserving user data privacy is an important research problem in cloud computing. The focus of this dissertation is to design secure and e cient schemes to address essential data utilization functions over encrypted data in cloud computing. To this end, we studied three problems in this research area. The rst problem that is studied in this dissertation is fuzzy multi-keyword search over encrypted data. As fuzzy search is one of the most useful and essential data utilization functions in our daily life, we propose a novel design that incorporates Bloom lter and locality-sensitive hashing to ful ll the security and function requirements of the problem. Secondly, we propose a secure index which is based on the most popular index structure, i.e., the inverted index. Our innovative design provides privacy protection over the secure index, the user query as well as the search pattern and the search result. Also, users can verify the correctness of the search results to ensure the proper computation is performed by the cloud. Finally, we investigate an important privacy-sensitive data application in cloud computing, i.e., genetic testings over DNA sequences. To provide secure and e cient genetic testings in the cloud, we utilize predicate encryption and design a bilinear pairing based secure sequence matching scheme to achieve strong privacy guarantee while ful lling the functionality requirement e ciently. In all of the three research thrusts, we present thorough theoretical security analysis and extensive simulation studies to evaluate the performance of the proposed schemes. The results demonstrate that the proposed schemes can e ectively and e ciently address the challenging problems in practice.

Deciphering Individuals' Preference for User Generated Content: An Empirical Test of the Impact of Personality on Users' Processing of Online Review Information Completed Research Paper

The explosive growth of user generated content presents a window of opportunity for online service providers (i.e., online review website) to utilize both forms of review information, namely numerical rating and opinionated review to facilitate trust building with users. Nevertheless, users’ trust in a website can be undermined by the irreconcilable dissonance between both forms of review information and their personality preferences. Consequently, it is important for websites to personalize the provision of numerical rating and opinionated review in order to convey trustworthiness to users through online consumer review. To empirically validate our research mode, we conducted a field study on a custom developed online review website with a sample of 170 college students. Results suggest that dissonance between numerical rating and opinionated review, as well as individuals’ preferences for self0 reference and content relevance when processing online review information moderate the positive relationship between online consumer review and trust.
American hegemony: intellectual property rights, dollar centrality, and infrastructural power

Abstract How does dollar centrality persist in the face of continuous US current account deficits and a steadily worsening net international investment position? Two mechanisms create a structural basis for dollar centrality, explaining how dollars enter global credit markets and why surplus countries continue to hold dollar-denominated assets. First, institutional structures deriving from late development suppress domestic demand in major current account surplus countries, making them reliant on external demand for growth. Local banks recycle those dollars into the global economy, creating huge dollar liabilities and assets on their balance sheets. This locks them into continued use of the dollar and reliance on the US Federal Reserve during crises. Second, US firms participating in the global unbundling of production have constructed commodity chains in which they capture disproportionate shares of global profits through their control over Intellectual property. These profits sustain valuations and thus the attractiveness of dollar-denominated assets. Routinization in use of the dollar and compliance with Trade-Related Aspects of Intellectual Property Rights (TRIPS) and US controlled commodity chains creates infrastructural power in Michael Mann’s sense. This routinization sustains US geo-economic power in the face of persistent current account deficits and growing net international debt relative to US gross domestic product.
Anthropometrics, Physical Characteristics, Physiological Attributes, and Sport-Specific Skills in Under-14 Athletes Involved in Early Phases of Talent Development- A Review

Anthropometrics, Physical Characteristics, Physiological Attributes, and Sport-Specific Skills in Under-14 Athletes Involved in Early Phases of Talent Development – A Review The main purpose of this article was to review a series of studies (n=30) on anthropometrics, physical characteristics, physiological attributes, and sport-specific skills in athletes under the age of 14 involved in early phases of talent development. Among the main findings of this review were that (a) young athletes have favorable anthropometric characteristics when compared to their peers who do not participate in organized sports, (b) comparing athletes of different skill levels leads to contradictory findings, and (c) the level of maturation is an important covariant in children under the age of 14. A number of practical implications were suggested for researchers and practitioners involved in early phases of talent development.
Automated Classification of Textual Documents Based on a Controlled Vocabulary in Engineering

Automated subject classification has been a challenging research issue for many years now, receiving particular attention in the past decade due to rapid increase of digital documents. The most frequent approach to automated classification is machine learning. It, however, requires training documents and performs well on new documents only if these are similar enough to the former. We explore a string-matching algorithm based on a controlled vocabulary, which does not require training documents--instead it reuses the intellectual work put into creating the controlled vocabulary. Terms from the Engineering Information thesaurus and classification scheme were matched against title and abstract of engineering papers from the Compendex database. Simple string-matching was enhanced by several methods such as term weighting schemes and cut-offs, exclusion of certain terms, and enrichment of the controlled vocabulary with automatically extracted terms. The best results are 76% recall when the controlled vocabulary is enriched with new terms, and 79% precision when certain terms are excluded. Precision of individual classes is up to 98%. These results are comparable to state-of-the-art machine-learning algorithms.
The Acquisition Of Lexical Knowledge From The Web For Aspects Of Semantic Interpretation

This work investigates the effective acquisition of lexical knowledge from the Web to perform semantic interpretation. The Web provides an unprecedented amount of natural language from which to gain knowledge useful for semantic interpretation. The knowledge acquired is described as common sense knowledge, information one uses in his or her daily life to understand language and perception. Novel approaches are presented for both the acquisition of this knowledge and use of the knowledge in semantic interpretation algorithms. The goal is to increase accuracy over other automatic semantic interpretation systems, and in turn enable stronger real world applications such as machine translation, advanced Web search, sentiment analysis, and question answering. The major contributions of this dissertation consist of two methods of acquiring lexical knowledge from the Web, namely a database of common sense knowledge and Web selectors. The first method is a framework for acquiring a database of concept relationships. To acquire this knowledge, relationships between nouns are found on the Web and analyzed over WordNet using information-theory, producing information about concepts rather than ambiguous words. For the second contribution, words called Web selectors are retrieved which take the place of an instance of a target word in its local context. The selectors serve for the system to learn the types of concepts that the sense of a target word should be similar. Web selectors are acquired dynamically as part of a semantic interpretation algorithm, while the relationships in the database are useful to

Plasma fibrinogen level is related to intimal pathology in coronary spastic angina

Fibrinogen promotes atherosclerosis and thrombosis. To evaluate the possibility that plasma fibrinogen levels represent a marker of atherosclerosis or are a predictor of cardiac events in coronary spastic angina, we studied the relation between plasma fibrinogen values and coronary angioscopic findings. We measured plasma fibrinogen in 20 patients with coronary spastic angina, 19 patients with chronic stable angina and 22 control subjects. Percutaneous angioscopic examination was performed in the patients with coronary spastic angina at the site of vasospasm induced by acetylcholine and in those with chronic stable angina at the site of organic coronary stenosis. Fibrinogen levels were significantly higher in those with coronary spastic angina (308.4±83.0 mg/dl) and chronic stable angina (289.4±69.3 mg/dl) than in the controls (239.5±49.9 mg/dl) (p<0.01, coronary spastic angina vs control;p<0.05 chronic stable angina vs control). Angioscopy showed intimal injuries (hemorrhage, flap, thrombus and/or ulcer) in 9 of the 20 (45%) coronary spastic angina patients, and flap or ulcer in 2 of the 19 (11%) chronic stable angina patients. Hemorrhage and/or thrombus were shown in 6 of the 20 coronary spastic angina patients. In the coronary spastic angina group fibrinogen levels were significantly higher (p<0.05) in those with than without hemorrhage and/or thrombus (365.3±97.4 mg/dl vs. 238.9±65.4 mg/dl). These results suggest that elevated fibrinogen levels in patients with coronary spastic angina are associated with atherosclerosis and thrombus formation.
Detection and suppression of impulsive noise in speech communication systems

In the paper a method is presented for the removal of impulsive disturbances from noisy speech and musical signals. The algorithm is based on a detection-interpolation scheme. The design of the impulsive noise detector subsystem is motivated by the observation that linear prediction systems are quite adequate for the modelling of speech signals whereas they can not model impulsive disturbances. It is shown that transforming the speech signal to the glottal excitation may result in significant reduction of the scale of the speech signal to almost that of the excitation signal whereas the scale of impulsive noise does not decrease. This can lead to a significant improvement in the detectability of the noise pulses. Further improvement may be obtained by the application of a matched filter to the noisy excitation signal. The signal samples that are obliterated by impulsive noise are discarded and interpolated. The interpolation method produces a least squared error estimate of the missing samples using speech samples in the vicinity of the missing block and an estimate of the LPC model of the signal. It is shown that the performance of the interpolation system improves significantly when the LPC model incorporates long term correlation structure in addition to the usual short term correlation parameters.
