Modeling physical-layer impairments in multi-domain optical networks

The advantages of optical transparency are still confined to the boundaries of a domain, since the optical signals are subject to O/E/O conversions at the border nodes that separate two optical domains. The extension of transparent connections across domains requires advances both in the modeling of the impairments suffered by the optical signals as well as in devising strategies to exploit such models in practice. In this latter regard, one of the main challenges is to design information exchange models and protocols enabling optical bypass without disclosing detailed physical-layer information among domains. In this paper, we focus on the modeling and the exchange of impairment-related information between optical domains. We propose a model that conveniently captures the degradation experienced by an optical signal along a lightpath, and describe it use in the frontier between two neighbor domains. Our approach respects the privacy and administrative limits of carrier networks, while enabling the provision of transparent connections beyond domain boundaries. The model and strategies proposed in this paper generalize the contributions made by some of the most relevant works in the field, providing in this way a first attempt toward a unifying view and theory for quantifying the transmission impairments in DWDM optical networks.
A high-precision linear method for camera pose determination

This paper concerns a high-precision linear method for camera pose determination. The key idea is to replace the algebraic error in the classical linear method with the weighted algebraic error as an approximation of the geometric error. The proposed method provides a linear solution with accuracy closed to that of maximum likelihood (ML) estimation, but more efficient than ML estimation. Based on the EPnP algorithm [15], we obtain the weighted EPnP (WEPnP) algorithm by using the weighted linear technique. Experiments on simulative data and real images show that the WEPnP algorithm significantly outperforms the EPnP algorithm, what's more, it even outperforms the Lu's nonlinear algorithm [13] in the case of small depth ratio.
Challenges and implementation of ad-hoc water gauge system for the grasp of internal water damage

In recent years, and landslides caused by flooding of the river due to heavy rain, the number of such flooding of houses has increased. With regard to internal water damage, the structure and of the river, above sea level and, such as where a landfill, how completely prevent flood damage by internal water is difficult. At present, it is only possible addressing of Operating the drainage devices typified by car to pump submerged location. However, in order to quickly drained work as possible, it is necessary to understand the full flooding water by the water level data of the flooding point throughout. To that end we have done a prototype of a portable ad hoc simple water gauge for the purpose of installation in the field in collaboration with Nippon Koei Co., Ltd. In particular, in a portable of the wireless sensor networks, communication reliability is greatly influenced by the surrounding environmental factors by communication node movement. Therefore, differ from the fixed wireless sensor networks. It, the radio wave condition and buildings around which changes due to the movement, is the effect of such plants. Furthermore, features and issues required portable ad hoc simple water gauge system is operated in the actual disaster site, it is necessary to determine standing worker eyes for performing production. In this paper, it is possible to organize the task of ad hoc simple water gauge system that assumes the movement, was carried out implementation of portable wireless sensor networks.
The voluntary feed intake of pigs given feeds based on wheat bran, dried citrus pulp and grass meal, in relation to measurements of feed bulk

Two experiments were carried out to investigate the capacities of pigs for bulky feeds. In Expt 1 fifteen pigs were offered, from 12 to 25 kg live weight, ad lib. access to one of five feeds which were made by progressively diluting a high-quality feed with wheat bran. Intake initially increased, and then declined, as the proportion of wheat bran was increased. The pigs became better able to accommodate to the more bulky feeds over time. In Expt 2 thirty-six pigs, initially of 12 kg live weight, were used. The feeds were the same high-quality basal feed as in Expt 1 and three others made almost entirely of either wheat bran, dried grass or dried citrus pulp, respectively. The equal-parts mixtures of each of these three bulky feeds with the basal feed were also made to give three series of feeds each comprising the basal, the mixture and the bulky feed. The three feeds in each series were given ad lib. to twelve pigs in a design of two replicated Latin squares with three time-periods. Within each series, and across periods, the intakes of the feeds that were limiting intake were directly proportional to live weight and so a scaled intake, expressed as g/kg live weight per d, was calculated. Across the six limiting feeds, scaled intakes in the final 5 d of each period, when the pigs were in equilibrium with their feeds, were directly proportional to the reciprocal of the water-holding capacities (WHC) of the feeds, as measured by a centrifugation method. There were large effects of feed changes on intake, in the short term, with previous experience of a bulky feed leading to higher intakes of another bulky feed. The intake of the basal feed was not affected by the feed given previously. It was concluded that: (a) the time of adaptation to bulky feeds needs to be considered when attempting to measure, or predict, the rates of intake on different bulky feeds and, (b) the WHC of the feeds could be an appropriate measurement of‘bulk’responsible for limiting their intake, and could be used to predict the maximum feed intake capacity of pigs on different bulky feeds.
Bit-plane extension to a class of intensity-based corner detection algorithms

Corners are important image features whose detection is very important in many computer vision tasks. In this paper we have evaluated the performance of five intensity based corner detectors with the help of a dozen test images, artificial and real, based on six performance measures of which three are proposed by us. We then propose a new approach, using bitplane decomposition, in which a grayscale image is first divided into several bit-planes, and then the original corner detectors are applied on all the bit-planes simultaneously and finally using a threshold, all the higher bit-plane corners are recombined up to the thresholded bit-plane to obtain the final set of corners. Using this approach, we have seen that the performance of the algorithms has improved significantly with respect to both detection and time.
Learning about teacher leadership through the lived experiences of high school teacher leaders

As more researchers have studied the benefits of treating schools and learning as complex systems, educators have taken this to a more practical level by encouraging leadership capacity at the grassroots level. On the whole, teacher leadership is used as both a corrective strategy and an empowerment tool to improve our schools. In British Columbia, Canada, the concept of teacher leadership is gaining increased attention; however, its practical application is less well understood. While recent literature has pointed to the value of looking at the distributed and paradoxical frameworks of teacher leadership, very little research to date can provide empirical evidence on the impact that these ideas have on teachers. In particular, it is not clear how different facets of teacher leadership experiences influence teachers’ beliefs, understandings, and emotions, and how these shape emergent practices of leadership. In this study, eight teacher leaders in a large urban school district in British Columbia participated in one-on-one interviews in an effort to add to our understanding of teacher leadership based on these teachers’ lived experiences. The research data was presented as eight vignettes revealing i) what teachers derived from their lived experiences in shaping their role as leaders of teacher-led initiatives, and ii) how teachers’ lived experiences in school initiatives (re)defined their future role as leaders. The participants drew from the personal, professional, cultural, socio-political, and structural dimensions of the work environment and spoke about common themes in their leadership experiences. Furthermore, as a group, they demonstrated certain personal and professional attributes that defined their positions as teacher leaders. The understanding gained from this study enriches our existing views of teacher leadership. By examining this phenomenon through the lens of distributed and paradoxical frameworks, this study brings contribution to the reconceptualization and future development of teacher leadership practices.

Effect of number of faults on NoC power and performance

According to international technology roadmap for semiconductors (ITRS), before the end of this decade, we will be entering the era of a billion transistors on a single chip. The major threat toward the achievement of billion transistor on a chip is poor scalability of current interconnect infrastructure. With the advent of "network on chip (NoC)" various characters and methodologies of traditional networks were hardly considered on-chip. Failure, power and area are the major concepts that should be considered when migrating from traditional interconnection networks to NoCs. In this paper we study the effects of faulty links and nodes on power and performance of mesh based NoC, Also several routing algorithms have been implemented and simulated using a cycle accurate VHDL model of NoC.

The flexible-width TAM architecture is combined with HR algorithm to calculate the value of fitness function in HGA. This HGA based method was implemented in C and applied to ITC’02 SOC Test Benchmark. Experimental results show that lower testing time was obtained by this new method compared to other
European Conference on Information Systems ( ECIS ) 5-15-2012 RELATIVE EFFICIENCY OF IT OUTSOURCING GLOBAL DELIVERY MODELS : A RESOURCE-BASED PERSPECTIVE

In the face of rising customer sophistication, changing industry economics, and intensified competitive pressures, common IT service delivery strategies are outdated these days. IT providers increasingly shift from traditional point-to-point offshore outsourcing to sourcing from a range of global locations. Within just a few years, delivery centres have been built up in multiple geographically dispersed countries. This determines the development of a business strategy referred to as global delivery model (GDM). Despite the emergence of GDM to become a preferred strategy in IT outsourcing, little is known about the performance of these relatively novel network structures. Against this background, we aim to examine the relative efficiency of GDMs offered by IT providers. This paper presents the results of the first stage of a two-stage research project. Drawing upon the resource-based view of the firm, we developed a conceptual framework of how providers’ GDM-related resources impact market performance. Furthermore, we introduce data envelopment analysis (DEA) as a methodology to assess relative efficiency in global delivery. Finally, we conducted a preliminary study to test the appropriateness of DEA for our endeavour and to provide first insights into global delivery
Treatment of ocular hypertension and open angle glaucoma: meta-analysis of randomised controlled trials

Abstract Objective Open angle glaucoma is one of the most common causes of blindness in industrialised nations. Treatments to lower ocular pressure are widely used in glaucoma prevention and treatment, despite conflicting evidence. Design We performed meta-analyses to reassess the effectiveness of pressure lowering treatment to delay the development of glaucoma in ocular hypertension, as well as progression of manifest open angle glaucoma. Data sources Medline, Embase, and the Cochrane Library. Selection of studies Eligible studies were randomised controlled trials with a concurrent untreated control group and information on time to glaucomatous changes to visual field and optic disc. Trial reports were reviewed independently by two investigators in an unblinded standardised manner. Results Meta-analysis of trials in ocular hypertension showed a significant preventive effect of reducing intraocular pressure on progression to glaucoma (hazard ratio 0.56, 95% confidence interval 0.39 to 0.81, P = 0.01; number needed to treat 12). Pooled data of studies in manifest glaucoma showed a significant delay of visual field deterioration (0.65, 0.49 to 0.87, P = 0.003; NNT = 7), with subgroup analysis showing a larger effect in patients with raised pressure and a reduced effect in normal tension glaucoma (subgroup comparison: not significant). Conclusions Lowering intraocular pressure in patients with ocular hypertension or manifest glaucoma is beneficial in reducing the risk of visual field loss in the long term.
Hybrid Reduction of Non-Symmetric MIMO Systems

A model order reduction algorithm is derived, which is suitable for linear systems with a large number of inputs and outputs. The full system matrices may be non-symmetric, singular and do not require other properties like positive definiteness. Such systems typically arise from finite element discretization of partial differential equations describing coupled mechanical, electrical, acoustical, etc. problems.
A pathophysiological view of the long non-coding RNA world

Because cells are constantly exposed to micro-environmental changes, they require the ability to adapt to maintain a dynamic equilibrium. Proteins are considered critical for the regulation of gene expression, which is a fundamental process in determining the cellular responses to stimuli. Recently, revolutionary findings in RNA research and the advent of high-throughput genomic technologies have revealed a pervasive transcription of the human genome, which generates many long non-coding RNAs (lncRNAs) whose roles are largely undefined. However, there is evidence that lncRNAs are involved in several cellular physiological processes such as adaptation to stresses, cell differentiation, maintenance of pluripotency and apoptosis. The correct balance of lncRNA levels is crucial for the maintenance of cellular equilibrium, and the dysregulation of lncRNA expression is linked to many disorders; certain transcripts are useful prognostic markers for some of these pathologies. This review revisits the classic concept of cellular homeostasis from the perspective of lncRNAs specifically to understand how this novel class of molecules contributes to cellular balance and how its dysregulated expression can lead to the onset of pathologies such as cancer.
Application-Specific Music Transcription for Tutoring

Automatic music transcription (AMT) refers to the ability of computers to write note information, such as the pitch, onset time, duration, and source of each sound, after listening to the music. Our application scenario is computer-assisted, musical-instrument tutoring, where the user has to practice most of the time without human coaching. The target users of our initial system are beginning violin students and singing students who are comfortable with computers. After consulting with a professional violin teacher and collaborators from our University's Conservatory of Music, we tried the following three strategies to build a system that can be tested by users.

Therefore, it is important to provide users with a secure channel for communication. This survey paper will give a brief introduction to the various generations of cellular networks. For those not familiar with the cellular network architecture, a brief description of the new 3G cellular network architecture will be provided. Limitations of cellular networks, their security issues and the different types of attacks will be discussed. Then the steps taken in the new 3G networks to combat the different security threats will be provided. Also, the security features of the Wireless Application Protocol (WAP) used to access the Internet will be discussed. The paper will go over some new security mechanisms that have been proposed by researchers.
Pacemaker implantation in small hospitals: complication rates comparable to larger centres

Aims Some countries have a demography that makes it necessary to maintain relatively small pacemaker centres. We wanted to assess the quality of pacemaker surgery in two such hospitals. Methods and results Through patient records we gathered information on ∼535 consecutive primary pacemaker implantations in two small pacemaker centres with 30 and 80 annual operations, respectively. All patients were followed for 3 years. All complications documented in the patient records were registered. Furthermore, we performed a non-systematic literature search comparing our data with reports from major centres published over the last 10 years.We found 72 complications in 64 (12.0%) of the patients, the most common being bleeding, lead failure, and pneumothorax. If minor bleedings without any consequences for the patients are excluded, the number of complications was 46 in 40 patients (7.5%). We had to reoperate on 5.2% of the patients. There was no statistically significant difference in complication rates between the two hospitals. Education candidates generated statistically significant more complications than experienced doctors (13.7 vs. 7.1%, P < 0.05). Conclusion There are no generally accepted norms of complication rates in pacemaker surgery. However, we found no indications that our centres have a rate of complications that is unacceptably high.
Associated with Galectin-1-Like Protein Complement Receptor 3 of Macrophages Is

We have previously identiﬁed a 16-kDa protein with a pI of 5.1 (P16/5.1) that is associated with macrophage CR3. Microsequencing of P16/5.1 indicated exclusive homology to the b -galactoside-binding lectin, galectin-1. Abs speciﬁc to a galectin-1 unique peptide reacted with P16/5.1. The association of P16/5.1 with CR3 was speciﬁcally inhibited by lactose, which binds with high afﬁnity to galectin-1. These data together with similarities in molecular mass and pI suggest that P16/5.1 is galectin-1. Two-color immunoﬂuorescence staining revealed the expression of galectin-1 on the macrophage surface and its colocalization with CR3. However, a surplus of CR3 was free of galectin-1, and some galectin-1 molecules were associated with cell surface receptors other than CR3. Based on these results we propose two models depicting the functional signiﬁcance of CR3-galectin-1 association: 1) homodimeric galectin-1 possessing a divalent sugar binding site may act as an extracellular adapter molecule that cross-links CR3 with other receptors; and 2) association of galectin-1 with b -galactosides on the extracellular domain of CR3 may modify the binding afﬁnity of the receptor to its ligand. These possibilities are not mutually exclusive and can clarify the mode by which CR3 transmits signals in macrophages. The Journal of Immunology, 1998, 160: 6151–6158.
Control of Sediment Export From The Forest Road Prism

The effectiveness of four road turn–out ditch treatments (vegetation, rip–rap, sediment fences, and settling basins) in reducing sediment export to the forest floor was evaluated. These four runoff control methods are commonly prescribed to control forest road runoff and sediments. The study utilized runoff samplers, runoff diversion walls, sediment filter bags, and erosion stakes to evaluate runoff concentration reductions through the treatments and sediment export downslope of the treatments. Settling basin, sediment fence, and vegetation treatments had no significant differences in runoff concentration reductions, which averaged more than 40%. The rip–rap was significantly less effective at reducing runoff concentration than were either the vegetation or sediment fence. The sediment basins were very effective during smaller storm events, but not during the largest storms, when they overflowed. The sediment basin exported the least amount of smaller–sized sediment that is likely to be delivered to stream systems.
Dynamic spectrum access with goe-location database: A utility-based distributed learning approach

This article investigates the problem of efficient distributed dynamic spectrum access in self-organizing networks with goe-location database, using a game theoretic approach. In particular, we propose a novel utility function, which aims to complete the data transmission of users and improve the satisfactory level of network by considering the efficient use of TV White-space Spectrum (TVWS) resource. Moreover, we formulate the problem as a distributed TVWS access game model. Compared with the traditional utility functions, the proposed function indicates a higher network satisfactory level than some others. To ensure that the network operates in a steady state, a learning-automata based uncoupled algorithm is used. Simulation results validate that the proposed utility function improves the network satisfactory level greatly.
