Efficient Vision Data Processing on a Mobile Device for Indoor Localization

The paper presents an approach to indoor personal localization using a sequence of captured images. The solution is tailored specifically for processing vision data on mobile devices with limited computing power. The presented FastABLE system is based on the ABLE-M place recognition algorithm, but introduces major modifications to the concept of image matching, in order to radically cut down the processing time, and to improve scalability. FastABLE is compared against the original OpenABLE and the popular OpenFABMAP place recognition systems.
Development of a novel voice verification system using wavelets

This paper presents a novel voice verification system using wavelet transforms. The conventional signal processing techniques assume the signal to be stationary and are ineffective in recognizing non stationary signals such as the voice signals. Voice signals which are more dynamic could be analyzed with far better accuracy using wavelet transform. The developed voice recognition system is word dependant voice verification system combining the RASTA and LPC. The voice signal is filtered using the special purpose voice signal filter using the relative spectral algorithm (RASTA). The signals are de-noised and decomposed to derive the wavelet coefficients and thereby a statistical computation is carried out. Further the formant or the resonance of the voices signal is detected using the linear predictive coding (LPC). With the statistical computation on the coefficients alone, the accuracy of the verifying sample individual voice to his own voice is quite high (around 75% to 80%). The reliability of the signal verification is strengthened by combining entailments from these two completely different aspects of the individual voice. For voice comparison purposes four out five individuals are verified and the results show higher percentage of accuracy. The accuracy of the system can be improved by incorporating advanced pattern recognition techniques such as hidden Markov model (HMM).
Mobile Internet Router for Multihop Ad hoc Networks

Future wireless ad hoc networks will use mobile routers to provide Internet connectivity to mobile ad hoc users. A mobile router also allows mobility of an entire ad hoc network, e.g. in plains, trains, cars, and other vehicles, where mobile users may use an Internet access within an ad hoc network domain. Mobile Internet access is also required for various mobile networks such as Personal Area Networks (PAN) and Body Area Networks (BAN). This paper describes the realization of a Mobile Internet Router and experimentally demonstrate the mobility of an entire multihop ad hoc network. The Mobile Internet Router must support so-called vertical handoffs for seamless mobility of an entire ad hoc network which roams between different access technologies. In this study, the concept design of a Mobile Internet Router is presented that uses Mobile IP for mobility support and connects a multihop ad hoc network (AODV) with wireless LAN (IEEE 802.11b) and a cellular system (GPRS). This paper examines the design of the proposed Mobile Internet Router and how it improves the routing performance of mobile ad hoc networking.
Low-cost gaze pointing and EMG clicking

Some severely disabled people are excluded from using gaze interaction because gaze trackers are usually expensive (above $10.000). In this paper we present a low-cost gaze pointer, which we have tested in combination with a desktop monitor and a wearable display. It is not as accurate as commercial gaze trackers, and walking while pointing with gaze on a wearable display turned out to be particularly difficult. However, in front of a desktop monitor it is precise enough to support communication. Supplemented with a commercial EMG switch it offers a complete hands-free, gaze-and-click control for less than $200.
Multiobjective optimization of echo state networks for multiple motor pattern learning

Echo State Networks are a special class of recurrent neural networks, that are well-suited for attractorbased learning of motor patterns. Using structural multiobjective optimization, the trade-off between network size and accuracy can be identified. This allows to choose a feasible model capacity for a follow-up full-weight optimization. It is shown to produce small and efficient networks, that are capable of storing multiple motor patterns in a single net. Especially the smaller networks can interpolate between learned patterns using bifurcation inputs.
Features, objects, action: The cognitive neuropsychology of visual object processing, 1984–2004

We review evidence on the cognitive neuropsychology of visual object processing, from 1984–2004, dividing the work according to whether it deals with the analysis of visual features, objects, or the relations between object processing and action. Research across this period has led to (1) a more detailed analysis of disorders of feature processing and feature binding, (2) a finer-grained understanding of disorders of object recognition, how these disorders can change over time, and their relations to visual imagery, and (3) new accounts of the relations between vision and action. Cognitive neuropsychological studies have played a key part in furthering our understanding of the functional nature of object processing in the brain.
The SPA2 gene of Saccharomyces cerevisiae is important for pheromone- induced morphogenesis and efficient mating

Upon exposure to mating pheromone, Saccharomyces cerevisiae undergoes cellular differentiation to form a morphologically distinct cell called a "shmoo". Double staining experiments revealed that both the SPA2 protein and actin localize to the shmoo tip which is the site of polarized cell growth. Actin concentrates as spots throughout the shmoo projection, while SPA2 localizes as a sharp patch at the shmoo tip. DNA sequence analysis of the SPA2 gene revealed an open reading frame 1,466 codons in length; the predicted protein sequence contains many internal repeats including a nine amino acid sequence that is imperfectly repeated 25 times. Portions of the SPA2 sequence exhibit a low-level similarity to proteins containing coiled-coil structures. Yeast cells containing a large deletion of the SPA2 gene are similar in growth rate to wild-type cells. However, spa2 mutant cells are impaired in their ability to form shmoos upon exposure to mating pheromone, and they do not mate efficiently with other spa2 mutant cells. Thus, we suggest that the SPA2 protein plays a critical role in cellular morphogenesis during mating, perhaps as a cytoskeletal protein.
A random coding theorem for "modulo-two adder" source network

This paper has been withdrawn by the author, due a crucial error in the proof of the main Theorem (Sec. 3). In particular, in deriving the bound on the probability of error (Eq. 10) the contribution of those pairs (x', y') that are not equal to (x, y) has not been considered. By adding the contribution of these pairs, one can verify that a region of rates similar to the Slepian-Wolf region will emerge. The author would like to acknowledge a critical review of the paper by Mr. Paul Cuff of Stanford University who first pointed out the error.
The Long-Period Method and Marx ’ s Theory of Value

This paper reconstructs Marx’s theory of value in the context of the long-period method of the classical political economists centered on the distinction between market prices and natural prices around which they gravitate. The theory of value stems from considering the abstract problem of the self-organization of a division of labor through the exchange of products as commodities. The commodity law of exchange, in which natural prices are proportional to social labor time necessary to produce commodities follows from assuming free mobility of labor. The capitalist law of exchange, in which natural prices equalize profit rates in different sectors arises from the assumption of free mobility of labor and capital. The classical political economists and Marx viewed labor at a level of abstraction where it is fungible between employments and skills. The theory of value is the full account of the allocation of universal labor and the emergence of natural prices in these abstract systems. Confusions in interpretation of the the theory of value are traced to inconsistent terminology and Marx’s polemical stance as a socialist revolutionary. ∗Please do not quote this draft, which is subject to revision, without permission.
Early warning model research of state-owned enterprises' human capital risks based on improved neural network

With the global economic integration and development of market economy, as well as relevant national regulations and policies to support independent innovation of enterprises, human capital has become the focus of enterprises, while in recent years state-owned enterprises' flow of human capital is frequent, especially in the northeast old industrial bases, the state-owned enterprises' flow of human capital is very serious. Therefore, it is necessary to adopt BP neural network algorithm to establish a three-layer BP neural network model to evaluate the stability of human capital in state-owned enterprises, which includes 31 nodes in input layer, 22 nodes in hidden layer, and 5 nodes in output layer. When we know the stability of human capital, we can take effective measures to ensure the healthy and sustained development of state-owned enterprises.
Investigation of I.C. samples using X-ray computer tomography

Structure complexity combined with high integration level in microelectronic industry is making the analysis more and more difficult. Non Destructive Analysis of either new semiconductor generation (e.g BGA, Flipchip) or double-sided printed circuit boards, is becoming very difficult as most of the critical structure features are hidden. Although 2D-X-rays inspection is still the most popular non- destructive inspection technique (with acoustic tomograp hy), we need advance inspection tools to improve our analysis capability. Micro 3-D tomography system, combining high-resolution microfocus X-rays technology with state of the art computer aided 3D -reconstruction possibilities provides an answer to technicians. After few minutes' data acquisition, the systems enables you to access to structure details, by using fast specimen non destructive slicing (layers analysis), and tomosynthesis 3D-reconstruction images. Test object can be visualized under arbitrary angles. As defect detectability is close to 20 microns with 3D mode, most of the critical features are detectable, without modifying specimen integrity. Several examples extracted from BGA, Flipchip, and PCB analysis show the advantage offered by this new tomography technique to microelectronic community.
Comprehensive Evaluation of High-Resolution Satellite-Based Precipitation Products over China

Characterizing the errors in satellite-based precipitation estimation products is crucial for understanding their effects in hydrological applications. Six precipitation products derived from three algorithms are comprehensively evaluated against gauge data over mainland China from December 2006 to November 2010. These products include three satellite-only estimates: the Global Satellite Mapping of Precipitation Microwave-IR Combined Product (GSMaP_MVK), the Climate Prediction Center (CPC) MORPHing (CMORPH), and Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN), as well as their gauge-corrected counterparts: the GSMaP Gauge-calibrated Product (GSMaP_Gauge), bias-corrected CMORPH (CMORPH_CRT), and PERSIANN Climate Data Record (PERSIANN-CDR). Overall, the bias-correction procedures largely reduce various errors for the three groups of satellite-based precipitation products. GSMaP_Gauge produces better fractional coverage with the highest correlation (0.95) and the lowest RMSE (0.53 mm/day) but also high RB (15.77%). In general, CMORPH_CRT amounts are closer to the gauge reference. CMORPH shows better performance than GSMaP_MVK and PERSIANN with the highest CC (0.82) and the lowest RMSE (0.93 mm/day), but also presents a relatively high RB (−19.60%). In winter, all six satellite precipitation estimates have comparatively poor capability, with the IR-based PERSIANN_CDR exhibiting the closest performance to the gauge reference. Both satellite-only and gauge-corrected satellite products show poor capability in detecting occurrence of precipitation with a low POD ( 40%).
Guideline-defined asthma control: a challenge for primary care

Primary care health professionals are faced with many challenges, not least of which are related to the complexities involved in diagnosing, investigating and managing asthma patients. This is further complicated by the fact that general practitioners (GPs), in their daily routine, are faced with patients presenting with hundreds of different types of medical, social and general problems, as opposed to specialist colleagues who deal with a relatively limited number of medical conditions. A typical consultation in general practice involves identifying the patient’s presenting problem, hypothesising possible aetiologies, examination, performing and arranging investigations, decisions on further management, addressing preventative medical issues (such as immunisations, cervical cytology and advice on lifestyle) and sometimes referral for specialist advice or care, all within time slots of 6–12 mins. It is therefore not surprising, though still shocking, that asthma diagnosis, reduction of symptoms through treatment and management of severely ill patients, who subsequently die from asthma 1, have been and continue to be major challenges for those working in primary care. Given the varying circumstances and working conditions experienced by GPs, application, implementation and adherence to guidelines in practice, during the consultation, provide further challenges. This subject has been researched and discussed extensively in the last two decades. Neville et al. 2 and later Pinnock et al. 3 demonstrated a clear lack of adherence in the 1990s to the British Guidelines for asthma care 4, 5, both by primary and secondary care colleagues. More recently, in 2005–2006, 15 Scottish general practices participated in an evaluation study 6 implementing three recommendations of the recent British Guidelines on the Management of Asthma 7. While the GPs’ awareness of the recommendations was fairly good, their implementation of one of these in particular was disappointing: only 58 (23%) out of 254 …
Mere projects or rebirth of a profession? An analysis of power and power structures in civic journalism

This paper seeks to analyse the achievements of civic journalism in the light of a possible application within Australasia. Once the foremost guardians of the ‘fourth estate’, journalists struggle. Newspapers have suffered from a significant loss in circulation and decreased public trust. Crossmedia ownership, and horizontal and vertical integration are increasing dangers for the effectiveness of media; especially the print branch. In the United States this shift in power has led to the civic journalism movement. At its core is the attempt to relocate journalism to its very roots. It calls for more orientation towards the public, seeing it as an active participator, source and audience for news stories. Stronger ties between journalists and the communities they work in are encouraged to regain accessibility for the reader and cover relevant issues in a meaningful way. Several civic journalism projects have been conducted and the movement has gained significant momentum within the last few years. It has also attracted a huge amount of criticism, though. Nonetheless it seems to be a promising tool to reinvigorate journalism. This holds especially true for countries like Australia or New Zealand, where the print media are predominantly owned by huge conglomerates (News Corp, Fairfax Group). However appealing civic journalism might seem; a closer analysis is necessary. The paper aims at accomplishing that by conducting a careful case study. It applies recent, mostly theoretical, criticism towards the featured high profile project to extract the movement’s merits and mistakes. By combining the comprehensive literature and projecting it on a best practice example it provides a new, holistic perspective on the shortcomings of civic journalism. The paper concludes by providing a perspective for practitioners and scholars alike, including a recommendation for the possibility and sensibility of further civic journalism projects in Australia and New Zealand.
Beyond Living and Dying: Applying a Flow Theory Perspective on Illegal Transborder Mon Labours in Thailand

Flow is an effective mental state in which an individual is so involved in an activity that time or space seem not to matter. This article investigates the “flow state” of illegal transborder Mon labours (ITMLs) from their home town in Mon State, Myanmar to Thailand during 2015-2017. The author employed qualitative research including interview in-depth and observations with thirty ITMLs. Then, the Boredom Proneness Checklist (BPC) were adopted to describe a negative experience of ITMLs. The flow state of optimal experience during their illegal transportations on AH1, Thailand revealed four motivational drivers of ITMLs. These were 1) cultural diffusion of passive, acceptance and boredom about their origin; 2) depression and inability to control their lives based on their own individual effort and creativity; 3) their personal skills of coverture equal required challenges; and 4) the holistic and joyful experience with total involvement during their journeys. For the ITMLs, the time of transportation was a motivating experience, especially for achieving their goal. The “flow” during transportation not only created self-satisfaction but also increased ability to 1) confront more challenging tasks; 2) learn to set clearer and higher goals for quality living; 3) control over individual actions; 4) forget about difficulties in time and space; and 5) establish a stronger sense of self-reliance. Keywords: Flow Theory, ITMLs
Improving fingerprint alteration detection

Fingerprint alteration is a type of presentation attack in which the attacker strives to avoid identification, e.g. at border control or in forensic investigations. As a countermeasure, fingerprint alteration detection aims to automatically discover the occurrence of such attacks by classifying fingerprint images as `normal' or `altered'. In this paper, we propose four new features for improving the performance of fingerprint alteration detection modules. We evaluate the usefulness of these features on a benchmark and compare them to four existing features from the literature.
Characterization and Computation of a "Good Control"

Models for physical systems often take the form of implicit or behavioral models. One important problem is the identification of which combinations of variables are good candidtates for control variables. This paper first provides one solution to this problem for linear time varying systems. The solution is shown to be related to a general optimization problem. It is then shown how these same algorithms can be extended to a large and important class of nonlinear systems.
Fabrication of Functional Metallic Nanowires Using Electrodeposition Technique

The array of numerous metallic nanowires with straight shape has much attention due to their shape anisotropy and extremely large surface area. This unique structure can be applied to develop the novel functional nano-materials such as electronic, magnetic and optical nano-scale devices. Metallic nanowires can be fabricated by manipulating metallic atoms one by one using a scanning tunneling microscope (STM) probe, while they can be also prepared by electrochemically depositing metallic atoms into a nanoporous template with numerous cylindrical nanopores. In a fabrication technique using electrodeposition of nanowires, nanoporous templates such as anodized aluminum oxide films with high density of nanopores (about 108~1010 pores•cm–2) have been used so far. In 1975, using an anodic oxide coating film on aluminum, magnetic properties of electrodeposited Co nanowires and Co-Ni alloy nanowires were investigated (Kawai & Ueda, 1975). In 1986, as an application to perpendicular magnetic recording medium, alumite films containing Fe nanowires were fabricated (Tsuya et al., 1986). In 1988, magnetization curling process in perpendicular direction was studied using Fe nanowire arrays in alumite media (Huysmans et al., 1988). In 1990, influence of the packing density on the magnetic behaviour was investigated using alumite media containg magnetic nanowires (Zhang et al., 1990). On the other hand, in 1991, using the polymer membrane template with numerous nanopores, polymeric and metal microtubules were synthesized (Martin, 1991). In 1993, arrays of Ni and Co nanowires were electrodeposited in polymer templates with the nanometer-sized pores prepared by nuclear track etching technique (Whitney et al., 1993). They found that the preferred magnetization direction is perpendicular to the film plane and enhanced coercivities as high as 680 Oe. Remnant magnetization of the nanowires up to 90% had been reported. In 1994, a membrane-based synthetic approach to obtain nanomaterials was introduced to materials science field (Martin, 1994). He suggested that the template synthesis method is useful to prepare polymers, metals, semiconductors, and other materials on a nano-scopic scale. In 1994, giant magnetoresistance (GMR) properties were found in Co/ Cu multilayered nanowires electrodeposited in nanoporous polymer template (Piraux et al., 1994). In the report, magnetoresistance measurements with the current perpendicular to the layers were performed on the array of parallel nanowires. They observed that the 15% of GMR at room temperature on Co/ Cu multilayered nanowires. In the almost same time, GMR of
PrePack: Predictive Packetizing Scheme for Reducing Channel Traffic in Transaction-Level Hardware/Software Co-Emulation

This paper presents a scheme called PrePack for suppressing the channel traffic between simulator and accelerator in the accelerator-based hardware/software co-emulation where the accelerator models some register transfer level (RTL) subblocks while the simulator runs transaction-level modeling (TLM) of the remaining part of the design under verification (DUV). With the conventional simulation accelerator, a cycle consisting of a pair of evaluations of simulator and accelerator occurs at every valid simulation time, which results in poor simulation performance due to the overhead of simulator-accelerator channel access, often accounting for more than 99% of total channel traffic time (total channel traffic time consists of channel-access time for arbitration/protocol exchange and pure data/signal transmission time). The overhead due to channel access can be reduced by merging as many channel transactions on the channel as possible into a single burst traffic, which is achieved in this paper by "prediction and rollback. " In the proposed "prediction and rollback" scheme, one of the two verification domains, i.e., software simulation and hardware acceleration, leads the other, while the leading domain predicts the states of the lagging domain. Therefore, the evaluation of simulator and accelerator no longer need to alternate at every simulation cycle. Under an ideal condition with 100% prediction accuracy, PrePack has shown a 15times speedup compared to the conventional scheme. When applied to advanced encryption standard (AES) and joint photographic experts group (JPEG) example systems, PrePack showed performance gains of 8.7 and 2.9, respectively
