Report from the field: results from an agricultural wireless sensor network

This paper reports the results of a 6-month deployment of a 65-node multi-hop network in a vineyard setting. This deployment specifically looked to discover ways in which a farm setting could find a return on investment for deploying such a network. Our ongoing collaborations of over two years ultimately have included everyone from the vineyard owners to the technology developers. We have been able to find several areas where wireless sensor networks deliver valuable information and provide a return on investment.
Effective Planning Skills and Other Dimensions of Classroom Management

Research and every teacher’s experience have proven that classroom management begins long before the students come into the classroom. Effective teachers plan their classroom management before the school year begins, and know what tasks they will need to undertake at the beginning and throughout the year. In general, classrooms with more structure have been shown to promote more appropriate academic and social behaviors. Effective planning skills do not only play an important role in the general teaching and learning process, but they also affect other dimensions of classroom management. In the study undertaken by the researcher, classroom management is presented in twelve dimensions which have been further presented in three domains. The main aim of this paper is to show the relationship of effective planning skills with other dimensions of classroom management. For the analysis of the data of this quantitative study, the SPSS (version 21) program was used. The participants of the study are 1020 students of secondary schools in three cities of Albania, Tirana, Elbasan and Durres. This paper will show how according to students’ perceptions, effective planning skills correlate with other dimensions of classroom management. From the statistical analysis of the data it was found that effective planning skills has a strong positive correlation with other dimensions of classroom management, like, effective implementation of lesson plans (rs = .796, n = 921, p < .005), assessment and feedback (rs = .708, n = 918, p < .005), knowledge of the subject matter (rs = .794, n = 964, p < 005), and teacher’s skills as motivator (rs = .730, n = 911, p < .005). Keywords: classroom management, effective planning skills.
A Channel Assignment Scheme for Location Service in Multi-Channel Mobile Ad Hoc Networks

In mobile ad hoc networks, multi-channel communication, compared to single-channel communication, can significantly improve the throughput of the networks. Channel assignment and routing are two basic issues in multi-channel networks. In this paper, we firstly present a channel assignment scheme for location service in multi-channel mobile ad hoc networks. The proposed channel assignment algorithm combines channel assignment and routing in grid level in order to reduce the complexity of channel assignment. The channel assignment in grid level will mitigate collisions and interference. Our channel ssignment algorithm only use one hop channel information for channel assignment. The performance of the proposed algorithms are evaluated by means of simulation. The simulation result shows that the proposed algorithms can effectively increase throughput and reduce delay, as compared to single-channel schemes.
Biological smart sensing strategies in weakly electric fish

Biological sensory systems continuously monitor and analyze changes in real-world environments that are relevant to an animal`s specific behavioral needs and goals. Understanding the sensory mechanisms and information processing principles that biological systems utilize for efficient sensory data acquisition may provide useful guidance for the design of smart-sensing systems in engineering applications. Weakly electric fish, which use self-generated electrical energy to actively sense their environment, provide an excellent model system for studying biological principles of sensory data acquisition. The electrosensory system enables these fish to hunt and navigate at night without the use of visual cues. To achieve reliable, real-time task performance, the electrosensory system implements a number of smart sensing strategies, including efficient stimulus encoding, multi-scale virtual sensor arrays, task-dependent filtering and online subtraction of sensory expectation.
Statistics for near independence in multivariate extreme values

We propose a multivariate extreme value threshold model for joint tail estimation which overcomes the problems encountered with existing techniques when the variables are near independence. We examine inference under the model and develop tests for independence of extremes of the marginal variables, both when the thresholds are fixed, and when they increase with the sample size. Motivated by results obtained from this model, we give a new and widely applicable characterisation of dependence in the joint tail which includes existing models as special cases. A new parameter which governs the form of dependence is of fundamental importance to this characterisation. By estimating this parameter, we develop a diagnostic test which assesses the applicability of bivariate extreme value joint tail models. The methods are demonstrated through simulation and by analysing two previously published data sets.
User innovation , design space , and everyday practices : Rodeo Kayaking case revisited

User innovation school by Eric von Hippel and his numerous co investigators has done ground braking work in exploring how and why users innovate, in identifying lead-users and contributions from user innovation communities. The present paper focuses on four understudied issues in this framework that come visible when one re-examines the analysis of rodeo-kayaking by Baldwin, Hienerth and von Hippel (2006) and Hienert (2006) originally geared towards exploring the role of user-innovators in industry development also after the earliest stages. These themes are 1) the scope of user innovation; 2) the evolution of design space for a user practice; 3) the range of ways users are involved in innovation; and 4) the range of users that are innovative in design relevant ways. The findings related to these issues add some qualifiers and suggest re-phrasings to some of the questions user-innovation school asks about user-innovation and industry development.
Update in asthma 2006.

Asthma-related investigations reported in 2006 ranged from the characterization of clinical asthma and airway obstruction (1–4), to human biologic studies (5, 6) and the use of animal models to better understand pathobiologic mechanisms at a cellular and molecular level (7–19). The concept of “risk” has been featured prominently, with articles identifying factors that increase the risk of developing asthma (20–24) as well as those aimed at identifying risk factors for asthma exacerbations and adverse outcomes (25–29). Studies have continued to explore the utility of noninvasive biomarkers (exhaled nitric oxide, exhaled breath condensate) to identify (30, 31), modify (32), and treat disease while increasing understanding of pathophysiologic mechanisms in asthma (33, 34). Clinical trials have sought to optimize treatment with established asthma drugs (35–37) and to evaluate novel modalities to fill voids in our current armory of asthma medications (38–40). Overall, this year has been an interesting journey, particularly in clinical asthma research, challenging accepted concepts in asthma therapy, and urging clinicians to expand their assessment of patients to identify and modify patient risk in addition to traditional measures of asthma control (41).
GALBF: Geodesic-Aided LBF method

In this paper, we propose a new active contour model that can be used to segment images with intensity inhomogeneities. The proposed method integrates geodesic curves with LBF method. We refer to this as the Geodesic-Aided LBF method. Moreover, a novel method based on local information for variational level set is added to the level set regularization term in the energy functional. It can not only ensure accurate computation, but also avoid expensive re-initialization of the level set function. Experiments on synthetic and real images demonstrate the advantages of the proposed model over the C-V model and the LBF model in terms of efficiency.
Role of non-coding RNA transcription around gene regulatory elements in transcription factor recruitment

ABSTRACT Eukaryotic cells produce a variety of non-coding RNAs (ncRNAs), many of which have been shown to play pivotal roles in biological processes such as differentiation, maintenance of pluripotency of stem cells, and cellular response to various stresses. Genome-wide analyses have revealed that many ncRNAs are transcribed around regulatory DNA elements located proximal or distal to gene promoters, but their biological functions are largely unknown. Recently, it has been demonstrated in yeast and mouse that ncRNA transcription around gene promoters and enhancers facilitates DNA binding of transcription factors to their target sites. These results suggest universal roles of promoter/enhancer-associated ncRNAs in the recruitment of transcription factors to their binding sites.
On the Complexity of Testing Implications of Functional and Join Dependencies

It iS shown that testing whether a dependency o is unpiled by a set ~ of functional and join dependencies is NP-hard if o is a join dependency, but it reqmres only O(l u Ill ~ II) time ff o Is either a funcuonal or a multivalued dependency ( j U [ is the number of elements in the set of all the attributes U, and II ~ II as the space required to write down ~). The fact that inferring join dependencies is NP-hard follows from the followmg stronger result. It is proved that if ~ is a set of one jom dependency and several funcuonal dependencies, then testing whether Z implies a join dependency o is NP-complete By combming this result with a recent result of Beeri and Var& ~t can be proved that if 2 is a set of one join dependency and several multivalued dependencies, then testing whether ~ unphes a join dependency o Is NP-hard It is also shown that the problem of deciding whether a JD-rule can be applied to a tableau T and the problem of testing whether a relation r does not obey a join dependency are NP-complete. The first problem is NP-complete even if T can be obtamed from a tableau corresponding to a join dependency by applying some FD-rules. As a result, It follows that deciding whether the join of several relations obtained by projecUon from a umversal instance is not equal to the universal instance is NP-complete. Finally, it is proved that there is no umversal constant n such that for every set of multlvalued dependencies ~ and a join dependency o that is not unpiled by ~, there is a relation with no more than n tuples in which holds but o fails.
Regimes of justification: competing arguments and the construction of legitimacy in Dutch nature conservation practices

Legitimacy of environmental management and policies is an important topic in environmental research. Based on the notion of ‘regimes of justification’, we aim to analyse the dynamics in argumentations used to legitimize and de-legitimize Dutch nature conservation practices. Contrary to prior studies, we demonstrate how actors in two locations where environmental disputes arose showed little willingness to switch between arguments in order to reach a compromise. Instead, some actors constructed incompatibilities between arguments in order to delegitimize competing actors. Especially in the visioning phase, institutional actors emphasized technical efficiency, planning and global environmentalism, and arguments related to emotional accounts, inspiration and locality were de-legitimized. In the discussion, we argue that it is not the formal or informal inclusion of the actors in the process, but the construction of the legitimacy of their arguments that determines the inclusiveness and outcome of the process.
Post-Quantum Secure Hybrid Signcryption from Lattice Assumption

Motivated by the demand to have secure signcryption scheme, even in quantum era, the concept of signcryption tag-KEM (key encapsulation machine) is extended to lattice cryptography in this paper. A lattice-based hybrid signcryption scheme is proposed by building a lattice-based signcryption tag-KEM. Based on the hardness of the learning with errors problem and the short integer solution problem, the proposed hybrid signcryption is provable secure in the random oracle model. Furthermore, according to the quantum intractability assumption about lattice problem, the proposed hybrid signcryption scheme is secure even on quantum computers.
Influence of link sensing mechanism of IMEP on the performance of TORA under different mobility models

The performance evaluation of Mobile Ad Hoc Network (MANET) routing protocols is an important as well as open area of research worldwide. Temporally Ordered Routing Algorithm (TORA) is an adaptable and distributed MANET routing protocol which is dependent on the services of Internet MANET Encapsulation Protocol (IMEP) for its various necessary functions like link status detection. The incorrect link failure detection by IMEP leads to creation of congested network and initiation of avoidable route maintenance in TORA. Thus changes need to be introduced in the link sensing mechanism provided by IMEP to improve the detection of links in TORA. According to previously available research, if the maximum number of OBM retransmissions is increased, significant improvement in the performance of TORA is noticed. This modification has been implemented in this paper and performance of Enhanced TORA is evaluated under Random-Waypoint model, Manhattan-Grid mobility model and Random-Direction model using FTP traffic with 10 connections. The results are then compared with those of original TORA using various performance metrics like Packet Delivery Ratio, Average End to End Delay and Routing Overhead.
Environmental Recognition Using RAM-Network Based Type-2 Fuzzy Neural for Navigation of Mobile Robot

Reactive autonomous mobile robot navigating in real time environment is one of the most important requirements. Most of the systems have some common drawbacks such as, large computation, expensive equipment, hard implementation, and the complexity of the system. The work presented in this paper deals with a type-2 fuzzy-neural controller using RAM-based network to make navigation decisions. The proposed architecture can be implemented easily with low cost range sensor and low cost microprocessor. To minimize the execution time, we used a look-up table and that output stored into the robot RAM memory and becomes the current controller that drives the robot. This functionality is demonstrated on a mobile robot using a simple, 8 bit microcontroller with 512 bytes of RAM. The experiment results show that source code is efficient, works well, and the robot was able to successfully avoid obstacle in real time
Offensive or defensive? – Application of DEA bootstrapping methodology on Chinese Professional Baseball League

Offensive or defensive? Which approach has the greater impact on winning professional baseball league games? Because the Chinese Professional Baseball League (CPBL) has only four teams, it offered a limited sample size for relevant studies. In this study, a window analysis was coupled with the sports team performance management model of the network data envelopment analysis (DEA) method to solve the problems of offense efficiency, defense efficiency and integrated efficiency of each of the CPBL teams from 2007 to 2014. Truncated regression was coupled with a bootstrapping method to perform a 2000 times repeated sampling, reduce the sampling error and determine the effect of environmental variables on the value of the efficiencies of the CPBL teams. The results show that the Lamigo Monkeys led in both offense performance and defense performance, whereas the United 7-ELEVEn led in integrated performance. The “total number of players” had a significantly positive impact on the efficiency of the teams. The 7-ELEVEn Lions and the Lamigo Monkeys showed superior performance with regard to the investment in the players and the long-term management of the depth of bench players, which verifies the importance of the depth of bench players in the CPBL. The “total bases gained” also had a significantly positive impact on the efficiency of the teams, which indicates the importance of the offensive capability for winning in the CPBL.
Multi-instanton calculus and equivariant cohomology

We present a systematic derivation of multi-instanton amplitudes in terms of ADHM equivariant cohomology. The results rely on a supersymmetric formulation of the localization formula for equivariant forms. We examine the cases of N = 4 and N = 2 gauge theories with adjoint and fundamental matter.
EGNOS test bed ionospheric corrections under the October and November 2003 storms

Two severe geomagnetic storms were experienced on October 29-31 and November 20, 2003, degrading significantly the European Geostationary Navigation Overlay Service (EGNOS) Test Bed (ESTB) performance in Europe. Such storms reached extreme values of Kp=9 during the most severe periods. The analysis of the ESTB ionospheric corrections and their effect on the ESTB integrity and accuracy is presented in this work. The ESTB performance during those storms was monitored from a network of global positioning system (GPS) receivers widely distributed over Europe, including the ESTB reference stations, and the geographical degradation of the accuracy is analyzed in this paper. The correlation between the Kp index and the misleading information (MI) events is also shown. During the most severe stormy periods, the errors in the ESTB ionospheric corrections and its integrity bounds are analyzed to explain the peaks in the navigation system error, which produces MIs. This analysis has been carried out by comparing with direct dual-frequency GPS measurements and global ionospheric maps.
Nutrition and Pregnancy after Bariatric Surgery

Obesity is an escalating problem in all age groups and it is observed to be more common in females than males. About 25% of women meet the criteria of obesity and one-third of them are in the reproductive age. Because morbid obesity requiring surgical treatment is observed with increasing frequency, surgeons and gynecologists are undergoing new challenges. It is not only a matter of women's health and their quality of life but also proper development of the fetus, which should be a concern during bariatric treatment. Therefore complex perinatal care has to be provided for morbid obesity patients. The paper reviews pregnancy and fertility issues in bariatric surgery patients.

Why TESLA Works : Innovative Agent-based Application Leveraging Schedule Flexibility for Conserving Energy

This paper presents TESLA, an agent-based application for optimizing the energy use in commercial buildings. TESLA’s key insight is that adding flexibility to event/meeting schedules can lead to significant energy savings. TESLA provides two key contributions: (i) three online scheduling algorithms that consider flexibility of people’s preferences for energy-efficient scheduling of incrementally/dynamically arriving meetings and events; and (ii) an algorithm to effectively identify key meetings that lead to significant energy savings by adjusting their flexibility. TESLA was evaluated on data of over 110,000 meetings held at nine campus buildings during eight months in 2011–2012 at the University of Southern California (USC) and the Singapore Management University (SMU), and it indicated that TESLA’s assumptions exist in practice. This paper also provides an extensive analysis on energy savings achieved by TESLA. These results and analysis show that, compared to the current systems, TESLA can substantially reduce overall energy consumption.
A modified architecture for high-density MRAM

This paper modifies the magnetic RAM (MRAM) architecture by removing a current rectifier per cell without sacrificing performance. A read operation of stored data is maintained by introducing a simple concept of"virtual ground" of operational amplifier. The modified MRAM design offers a reduced element area and therefore achieves an over tenfold improvement in storage density. The proposed architecture has been proven operable by an engineering experiment
Security protocol for controller area network using ECANDC compression algorithm

Controller area network (CAN) is the most extensively used embedded network protocol in vehicles. However, CAN is vulnerable to malicious security attacks as it enables unauthorized access in a relatively straightforward manner. In the last ten years, security attacks in vehicles have been increasing and reported in several documents. In this paper, we propose a security protocol for CAN system based on AES-128 encryption and HMAC function. In addition, by combining with CAN data compression algorithm, it is shown that the efficiency of the proposed algorithm can be significantly increased. We simulate the proposed security protocol using the CANoe software. The CAN bus load is measured using CANcaseXL device. Experimental results show that the average message delay with 20 ECUs is within 0.13ms and the bus load can be reduced by 18.41% using the proposed security protocol compared with the uncompressed message. Our results indicate that the proposed security protocol is suitable for use in real-time in-vehicle system.
SPATIAL-FREQUENCY DISCR~~INAT~QN OF DRIFTING GRATINGS

Spatial-frequency discrimination thresholds were measured for briefly (300 msec) presented sinewave gratings having a contrast one logarithmic unit above detection threshold. The gratings were drifted at rates varying from I. 1 to 40 Hz. In a two-interval forced-choice paradigm thresholds were determined for vertically and obliquely oriented gratings. Three reference spatial frequencies (I, 4, 12 c/deg) were tested. For the I c/deg reference spatial frequency, spatial-frequency di~~mination thresholds were constant over the wide range of drift rates used. For 4 and 12 c/deg reference gratings, discrimination thresholds were constant for drift frequencies up to 14 Hz. For drift frequencies beyond 14 Hz, spatial-frequency discrimination thresholds increased abruptly, rising from approx. 6% at 14 Hz to 25% at 40 Hz drift rate. Measurements with obIiquely oriented gratings yielded comparable results. The increase in the spatial-frequency discrimination threshold for medium-high spatial frequencies and high temporal frequencies might reflect an increase in the spatial frequency bandwidth of the mechanisms sensitive to these stimulus frequencies.
