Performance of Shuffled Frog-Leaping Algorithm in Finance-Based Scheduling

AbstractCurrently, meta-heuristics including the genetic algorithms (GA) and simulated annealing (SA) have been used extensively to solve non-deterministic polynomial-time hard (NP-hard) problems. Continued efforts of researchers to upgrade the performance of the meta-heuristics in use resulted in the evolution of new ones. Shuffled frog-leaping algorithm (SFLA) is one of the recently introduced heuristics. The few applications of the SFLA in the literature in different areas demonstrated the capacity of the SFLA to provide high-quality solutions. The main objective of this paper is to further bring the SFLA to the attention of researchers as a potential technique to solve the NP-hard combinatorial problem of finance-based scheduling. The performance of the SFLA is evaluated through benchmarking its results against those of the GA and SA. The traditional problem of generating infeasible solutions in scheduling problems is adequately tackled in the implementations of the GA, SA, and SFLA. Fairly large proj.
Applying mathematical software documentation: an experience report

Those who do not use "formal methods" for developing software (and they remain the overwhelming majority of software developers) often claim that mathematical software development can only be used by highly educated people, and on especially well-written programs. We counter this claim by reporting on some recent experience. An undergraduate engineering student who had no previous exposure to mathematical software documentation techniques was asked to use a new method to document a program that had been written for photonics and microwave development, but did not always work as required; the author had departed and the program's owners were not able to find the problem. The student was not asked to change the program, just to provide precise documentation. However, the process of documentation revealed several errors and, after they were corrected, the program was left in working, and maintainable condition. Our experience supports the position of those who believe that mathematical methods can be used by typical engineers with immediate benefits.
Survey of Modern Image Segmentation Algorithms on CT Scans of Hydrocephalic Brains

Abstract Paper presents the concept of applying image segmentation algorithms for precise extraction of cerebrospinal fluid (CSF) from CT brain scans. Accurate segmentation of the CSF from the intracranial brain area is crucial for further reliable analysis and quantitative assessment of hydrocephalus. Presented research was aimed at the comparison of effectiveness of three modern segmentation approaches used for this purpose. Specifically, random walk, level set and min-cut/max-flow algorithms were considered. The visual and numerical comparison of the segmentation results leads to conclusion that the most effective algorithm for the considered problem is level set, although the positive medical verification of the results revealed that either of considered algorithms can be successfully applied in the diagnostic applications.

Checkpoint inhibitors in Hodgkin's lymphoma

Hodgkin's lymphoma is unusual among cancers in that it consists of a small number of malignant Hodgkin/Reed–Sternberg cells in a sea of immune system cells, including T cells. Most of these T cells are reversibly inactivated in different ways and their reactivation may induce a very strong immune response to cancer cells. One way of reactivation of T cells is with antibodies blocking the CTLA‐4 and especially with antibodies directed against PD‐1 or the PD‐L1 ligand thereby reversing the tumor‐induced downregulation of T‐cell function and augmenting antitumor immune activity at the priming (CTLA‐4) or tissue effector (PD‐1) phase. Immune checkpoint inhibitors have been evidenced as an additional treatment option with substantial effectiveness and acceptable toxicity in heavily pretreated patients with Hodgkin's lymphoma. Particularly, PD‐1 blockade with nivolumab and pembrolizumab has demonstrated significant single‐agent activity in this select population.
A multivariate analysis of the Old English ACC+DAT double object alternation

In Old English, the ditransitive construction with an accusative (direct) object and a dative (indirect) object occurred with two alternating object orders: ACC-DAT vs. DAT-ACC. This study examines the motivations behind the OE speakers' choice for one of both orders. The effect of 16 factors was evaluated based on a corpus sample of N = 2409 sentences drawn from the York-Toronto-Helsinki Parsed Corpus of Old English Prose (Taylor et al. 2003). The data was analysed by means of a mixed-effects logistic regression analysis. The results indicate that the ACC+DAT alternation was largely driven by the same factors that motivate the dative alternation in later stages of British English. However, no evidence was found for specific verb preferences in Old English, which suggests that the OE object alternation was less driven by semantics than the dative alternation in PDE. It is argued that the results further substantiate Wolk et al.'s (2012) claim that the cognitive mechanisms underlying present-day probabilistic patterns also underlie past variation.
Study on an Adaptive Distributed Linear Dispersion Code

An adaptive distributed linear dispersion code is proposed in this article. In the first place, each relay code selects modulation type adaptively according to channel capacity. Then the candidate dispersion matrixes are selected based on the channel state weight. Finally the best transmission scheme is selected according to the system information rate and reliability. Simulation results show that the proposed adaptive coding scheme gives a more good performance.
Adefovir Dipivoxil, Tenofovir Disoproxil Fumarate or Lamivudine; Which is Suitable Monotherapy Medication in the Patients with Chronic Hepatitis B Virus Infection? One Year Experience

Introduction: The hepatitis B virus infection is responsible for more than one million deaths all over the world. This study design is to compare the efficacy of Lamivudine (LAM), Adefovir Dipivoxil (ADV) or Tenofovir Disoproxil Fumarate (TDF) monotherapy in chronically infected hepatitis B patients. Methods: We design a prospective cohort study and select patients who were under treatment with TDF (300mg/day), ADV (10mg/day) and LAM (100mg/day). After matching patient's primary data and on base of our inclusion and exclusion criteria; 19, 20 and 19 patients were enrolled in TDF, LAM and ADV groups, respectively. Then, we evaluated patients at 6 and 12 month after treatment. Results: Patents primary data was closely matched. After 6 month medication, ALT level in 7 patients (36.8%), 12 patients (60%) and 6 patients (31.6%) of TDF, LAM and ADV groups were back to normal range, respectively (P>0.05). All drugs significantly decrease ALT level after 6 month therapy (P 0.05). Finally, response to treatment was observed in 5 patients (45.5%), 7 patients (35%) and 2 patients (10.5%) of TDF, LAM and ADV group, respectively (P>0.05).
Looking beyond personal pronouns and beyond English: Typological and computational complexity in reference resolution

In their paper, Kehler and Rohde aim to reconcile two divergent approaches to pronoun interpretation, what they refer to as ‘coherence-driven’ and ‘Centeringdriven’, by means of a probabilistic Bayesian approach that incorporates insights from both traditions. On the one hand, according to coherence-based approaches based on Hobbs (1979, 1990), pronoun interpretation is a side-effect that falls out from general discourse-level processing: Comprehenders draw inferences about the coherence relations between sentences and interpret pronouns accordingly. On the other hand, instantiations of Centering Theory (e.g., Grosz, Joshi & Weinstein, 1995) tend to focus not on the semantic relations between sentences but rather operate on a ranked set of ‘centers’ (entities mentioned in the discourse) and use information-structural factors – in particular notions linked to topicality – to guide pronoun interpretation. Centering Theory allows for the centers to be ranked in different ways (to capture cross-linguistic variation), though researchers have often assumed that the ranking depends on grammatical role, such that subjects are ranked above direct objects, which are ranked above obliques, and so on. As Kehler and Rohde note, under coherencebased approaches to pronoun interpretation, semantics, world knowledge and inferences are crucial, but under Centering-based approaches, informationstructural notions such as topicality (related to grammatical roles) are of central concern. In the present paper, Kehler and Rohde present data from a series of experiments, showing that neither coherence-driven nor Centering-driven approaches alone are able to fully capture the data. Instead, they build on ideas introduced in Kehler 2002 and Kehler et al. (2008) and argue for a Bayesian approach in which
A Strategy of Constructing Heterogeneous Cost-Sensitive Decision Tree

Usually, the algorithm of constructing cost-sensitive decision tree assume that all types of cost can be converted into a unified units of the same price, apparently how to construct an cost conversion function is an challenge. In this paper, a strategy of constructing heterogeneous cost-sensitive decision tree is designed and the different cost are take into account together in split attribute selection. Whats more, an attribute selection model based on heterogeneous cost-sensitive is constructed and the pruning strategy based on cost-sencitive is designed. The experimental results show that the proposed method is correct and more efficient than the present other methods
Multimedia teleconferencing over international packet switched networks

A description is presented of the current configuration and projected future work on the world's first multimedia teleconferencing system. The communications architecture (by which the authors refer to the protocols and supporting network management system) is based around the DARPA Internet Protocol suite, but with certain enhancements to support real time traffic. The CODEC runs a standard bitstream encoding of video, and this is packetized by the PC. However, this is not sufficiently flexible a protocol to traverse the Internet. The stream protocol (ST) gateway then runs two further protocols to carry the video and voice: (1) packet video protocol (PVP) and (2) voice traffic protocol (VT). Each of these is tuned to the special requirements of video and voice. To carry these in a reasonably consistent fashion, the gateways then run the ST. The performance of the system is limited mainly by the bandwidth of the first few hops of the path. <<ETX>>

A mobile-assisted synchronously collaborative translation–annotation system for English as a foreign language (EFL) reading comprehension

This research introduced mobile devices into an intensive reading course and allowed functions that are usually found only in the language laboratory to be easily and flexibly utilized in the general classroom. To enhance and improve the reading comprehension of English as a foreign language (EFL) readers, a computer-assisted-language-learning (CALL) system for use on PDAs, integrating an instant translation mode, an instant translation annotation mode, and an instant multi-users shared translation annotation function was developed to support a synchronously intensive reading course in the normal classroom. Experiments were conducted to analyze the usage of the system, including the attitude and satisfaction of users. Moreover, the study determined the optimum number of users in each group for the system to work most efficiently, and for students to improve their reading comprehension. Experimental results indicated that those students who were grouped into twos, threes, and fours had significantly higher levels of comprehension than individual students, but those grouped into fives did not. Overall, on average around 70% of the students agreed that the system was useful, 75% of the students agreed that the system was easy to use, and 66% of the students perceived satisfaction with the system. The user intentions were also further analyzed in light of a path analysis method.
Combining Burst Detection for Hot Topic Extraction

As traditional text representations are not suitable for online dynamic streams, this paper presents a hot topic extraction technique that can be used for tracking news topics over time. The model combines individual word burst into the document-word vector representation, which can emphasize the temporally features of text streams. An energy ratio threshold based burst detection approach is proposed and TF-PDF is then combined to weigh the terms. Experiment results demonstrate that this model is effective in topic extraction for news stream and it can better improve the clustering performance.
Apical seal comparison of low-temperature thermoplasticized gutta-percha technique and lateral condensation with two different master cones.

Aim: To compare the apical sealing in mesio-buccal canals of extracted molars obturated with low-temperature ther- moplasticized gutta-percha or cold lateral condensation techniques using a . 06 or a . 02 mm/mm tapered gutta-percha master cone. The secondary aim was to evaluate the depth of spreader penetration in root canals using a . 06 or a . 02 mm/mm tapered gutta-percha master cone. Methodology: Forty-four mesio-buccal curved canals (25-40o) were instrumented with . 06 nickel-titanium rotary ins- truments and randomly distributed into two control groups (n=4) and three experimental groups (n=12) for obturation by the Ultrafil® 3D system or by cold lateral condensation with . 06 or . 02 tapered master cone. Canal sealer AH-Plus® was used. The depth of spreader penetration was recorded in millimetres. Roots were covered with two layers of nail polish, immersed in India ink for 7 days, transversally sectioned and examined with a stereomicroscope. Student's t test was used to determine whether there was a difference in spreader penetration between groups. Kruskal-Wallis test was used to determine whether there was a difference in leakage. Results: There were no differences among the three groups (p=0.396), which showed a very similar mean microleakage (0.42, 0.75 and 0.42). The difference in spreader penetration between the groups filled by cold lateral condensation was significant (p=0.001) Conclusion: The Ultrafil® 3D system and cold lateral condensation techniques with . 06 or . 02 tapered master cones were equally effective in the apical sealing of curved canals. The spreader penetrated deeper using a . 02 mm/mm tapered gutta-percha master cone.
Hop distances in homogeneous ad hoc networks

Given is the network-level view of a wireless multi-hop network with n uniformly distributed nodes, each of them with radio transmission range r/sub 0/, on a rectangular area. This paper investigates the discrete probability distribution of the minimum number of wireless hops H between a random source and destination node. This topology attribute has significant impact on the network performance, e.g., on route discovery delay and message delivery. We derive closed form expressions for the probability that two nodes can communicate within H = 1 hop (i.e., via a direct link) or H = 2 hops (i.e., over one relay node). Connection paths with H > 2 hops and the expected hop distance E{H} are studied by analytical bounds and extensive simulations.
Comparative analysis of conventional and multiuser detectors in multisensor receivers

Multiuser detection has been proposed to improve the performance of direct-sequence spread-spectrum code-division multiple-access (DS-CDMA) systems. Use of multiple sensors (antenna elements or base stations) can be used to improve the signal-to-noise ratio and counter the effects of fading in any communication system. In this paper, multisensor multiuser detection is analyzed. It is shown by analysis and numerical examples that the use of multiple sensors averages the multiple-access interference (MAI) out towards zero even without multiuser detection. The performance of linear multisensor receivers with and without multiuser detection is analyzed and compared. The examples show that relatively good performance can be obtained without multiuser detection with moderate number of users and under a reasonable near-far problem.
Bipolar micropower circuits for crystal-controlled timepieces

An electronic system for quartz crystal-controlled timepieces is described. Special attention is paid to the frequency divider, which is the heart of the whole system. A novel binary cell, which uses conventional bipolar technology, leads to low power consumption and small cell size in the frequency divider. The whole system is implemented in bipolar technology, thus enhancing reliability and simplifying processing.
Information and Social System Interaction

Ever increasing participation has made the interaction between information and social systems not only interesting to observe but essential to quantify and analyze. This dissertation presents methods for understanding such interaction through combined analysis of metadata, networks, text and log data. ArXiv, an open and highly influential scholarly communication system, served as the testbed for these methods. In the first part of this dissertation we examine in depth interesting phenomena such as self-promotion, procrastination, visibility and geographic differences. We have confirmed the predictive power of early readership through regression and discussed undesirable effects of recommendation and possibilities of new impact metrics. In the second part we demonstrate extraction of subtopical concepts, characterized by phrases, through a statistical method for vocabulary selection and a network based ranking. Validation via search query and click logs is advocated as relevant and scalable. A clustering scheme to summarize temporal patterns of topic clicks is also presented. In the last part of this dissertation we present a name disambiguation algorithm and a novel evaluation method using node role based sampling in the context of network analysis. Finally we provide guidelines on performing large scale graph computation using the Map-Reduce framework.
Adaptive extremum seeking control design

The paper focuses on an adaptive output-tracking problem using on-line extremum seeking command generation. Two interconnected dynamic uncertain subsystems are considered. Using direct adaptive neural network based control, both subsystems are forced to follow their corresponding trajectories. While the command for the first subsystem is predetermined, the command for the second subsystem is computed on-line such that the influence of the second subsystem on the first one is minimized. The problem is motivated by the need to design an autopilot for autonomous formation flight. The autopilot must perform in an aerodynamically uncertain environment. The control problem reflects two aircraft flying in a closed-coupled formation wherein the trailing aircraft must constantly seek an optimal relative position that minimizes the aerodynamic drag force induced by the wing vortices of the lead aircraft. Using feedforward neural networks and on-line extremum seeking command generation, the proposed control scheme provides bounded output tracking and minimizes the effect of uncertainty on the first subsystem's dynamics. Closed-loop system stability is shown using Lyapunov's direct method.
Experience as Meaning: Creating, Communicating and Maintaining in Real-Spaces

Designers of interactive systems have two main goals to attain. The first is to design a system with “appropriate” representations, interactions and functions. And the second is to see how the users use the designed system and what their experiences are. The first is the primary goal but depends heavily on the second. In this paper we focus on the second goal. The proliferation of novel computing technologies into our day-to-day social lives has imposed development of new perspectives to analyze different human activities and their attitude towards the technology. These technologies play a diversity of roles – widely beyond the traditional computing device, placing the non-technical product qualities such as pleasure, fun, trust, etc. amongst the set of main goals of system design. This new era of user-experience has challenged designers to understand human experiences and apply them into the design process. Experience is a subjective and holistic phenomenon [11] where users construct the eventual experience within the settings afforded by the environment. Clearly, the context where this interaction takes place plays an important role in defining the experience. Context has been interchangeably used to address spaces and places. However, Harrison & Dourish [7] argue that spaces are three-dimensional physical representation of context where the human activities are possible. Whereas places are referred to as the lived realities where the actual experience comes about. To them, “Space is the opportunity and place is the understood reality”. In this position paper, however, we focus on conceptualizing user-experience and see how context plays its part in it. We conceptualize experience as ‘meaning’ that is created, communicated and maintained by users during their interaction with the system.
