Exploiting Rigid Body Motion for SLAM in Dynamic Environments

The limitations of existing localisation and mapping algorithms in handling highly dynamic environments is a key roadblock in the deployment of autonomous mobile robotic systems in a range of important real world situations. In this paper we propose a technique to integrate the motion of dynamic objects into a Simultaneous Localisation and Mapping (SLAM) algorithm without the need to know a-priori or model the geometry of the object, or even to explicitly estimate the pose of the object. The benefit of this approach lies in a simplification of the underlying SLAM state and a resulting simplification of the non-linear least squares optimisation solution. We demonstrate the performance of the algorithm on two scenarios; SLAM in an urban traffic scenario, and extrinsic calibration of a multi RGBD camera system observing a moving object. Our experiments show consistent improvement in robot localisation and mapping accuracy and demonstrate potential of the proposed algorithm.
Blockchain ' s Relationship with Sovrin for Digital Self-Sovereign Identities

Sovrin is a blockchain technology for self-sovereign identities. This paper investigates what the blockchain technology accomplishes for the Sovrin network. Three cases are analysed to determine the differences between the physical, digital, and Sovrin domains. The Sovrin network is able to implement a system that is user-centric and follows the principles proposed by Sovrin’s self-sovereign identity model. Credentials on the Sovrin network allow users to identify themselves in a decentralised manner and privacy-preserving manner. Sovrin’s transaction flow of credentials incorporates many characteristics that are also present in the physical world. On top of that, Sovrin allows for better verification processes and real-time revocations compared to the physical world. We analyse the characteristics of the Web of Trust and compare it to the Sovrin network. Then, the main problems are identified that are solved by Sovrin. These problems are further analysed, and comparisons are made to the Sovrin implementation. We discuss if blockchain technology is a required part of the implementation of Sovrin to solve the identified problems. Finally, we conclude that blockchain technology is one of the possible solutions to the problems found.
Plan and Organize Acquire and Implement Deliver and Support Monitor and Evaluate Fig 2 : COBIT Process

By virtue of the multiplicity and diversity of laws regulating the field of information technology governance, those in charge of information systems in SMEs-SMIs are faced with a problematic of compliance obligation, especially that the laws are now of international and national order. This work is concerned with information systems security and the crucial role it plays to ensure an effective governance of information technology (IT). An essential component of internal control imposed by financial security laws as well as by major IT governance frameworks, the security of information systems is one main leverage for a policy of compliance and standardization. Indeed, compliance with laws and regulations with the aim of enhancing the transparency and credibility of the mechanisms of information production and operation needs the implementation of a set of procedures and controls that meet safety requirements in terms of availability, integrity and confidentiality. These procedures introduce major changes with regard, in particular, to information visibility within the business, organizational and management processes, and human resources management.
Stability Effect for Passive Dynamic Walker by Stance Leg Heel Angle Constraint Using Foot Shape

One of the methods known to stabilize a passive dynamic walk is to restrict a hip joint angle. The hip restriction method effects as resetting the walking dynamics every time at the beginning of the walk. A Constraining Foot Shape is known to give the same effect by a more compact configuration. However, it was not clear how much this dynamics resetting effect will be given for a specific design parameter such as a length of the foot. This paper shows a numerical approach for this. Firstly, we show a dynamics of walking by 2D stick model with foot length. This is realized by considering a support point exchange effect. Secondly, we show a simulation results by this model. From these, we show that a longer foot will give a more strong effect of resetting walking dynamics. Finally, we demonstrate the validity of the model by making an actual hardware of 2D stick model with foot length. In this model, a scuffing effect was avoided by using landing islands on a slope.
Drop Impact on a Solid Surface C

A drop hitting a solid surface, can deposit, bounce or splash. Splashing arises from the breakup of a fine liquid sheet which is ejected radially along the substrate. Bouncing and deposition depend crucially on the wetting properties of the substrate. In this review we focus on recent experimental and theoretical studies, which aim at unraveling the underlying physics, characterized by the delicate interplay of not only liquid inertia, viscosity and surface tension, but also the surrounding gas. The gas cushions the initial contact, it is entrapped into a central microbubble on the substrate and it promotes the so-called coronasplash, by lifting the lamella away from the solid. Particular attention is paid to the influence of surface roughness, natural or engineered to enhance repellency, relevant in many applications.
The effects of Chinese import penetration on firm innovation: Evidence from the Vietnamese manufacturing sector

This paper evaluates the impact of Chinese import penetration on the innovation of Vietnamese manufacturing firms from 2011 to 2015, exploiting variations in import exposure by industry specialization and instrumenting for Chinese import penetration using Chinese global exports. Contrary to the existing literature, the paper finds no systematic evidence that rising imports from China make domestic firms adopt new technologies or innovations in their products.
Low Power DSP-Based Transceivers for Data Center Optical Fiber Communications (Invited Tutorial)

In this tutorial, we discuss the evolution of the technology deployed for optical interconnects and the trade-offs in the design of low complexity, low power DSP and implementation for direct detect and coherent, pluggable optical modules for data center applications. The design trade-offs include the choice of modulation format, baud rate, optical link design, forward error correction, signal shaping and dispersion compensation.
A Multisite Preregistered Paradigmatic Test of the Ego-Depletion Effect

We conducted a preregistered multilaboratory project (k = 36; N = 3,531) to assess the size and robustness of ego-depletion effects using a novel replication method, termed the paradigmatic replication approach. Each laboratory implemented one of two procedures that was intended to manipulate self-control and tested performance on a subsequent measure of self-control. Confirmatory tests found a nonsignificant result (d = 0.06). Confirmatory Bayesian meta-analyses using an informed-prior hypothesis (δ = 0.30, SD = 0.15) found that the data were 4 times more likely under the null than the alternative hypothesis. Hence, preregistered analyses did not find evidence for a depletion effect. Exploratory analyses on the full sample (i.e., ignoring exclusion criteria) found a statistically significant effect (d = 0.08); Bayesian analyses showed that the data were about equally likely under the null and informed-prior hypotheses. Exploratory moderator tests suggested that the depletion effect was larger for participants who reported more fatigue but was not moderated by trait self-control, willpower beliefs, or action orientation.
Population responses to harvesting in fluctuating environments

: Achieving sustainable harvesting of natural populations depends on our ability to predict population responses to the combined effects of harvesting and environmental fluctuations while accounting for other internal and external factors that influence population dynamics in time and space. Here, we review recent research showing how spatial patterns and interspecific interactions can influence population responses to harvesting in fluctuating environments. We highlight several pathways through which harvesting can, often inadvertently, influence the dynamics and resilience to environmental fluctuations of both harvested and surrounding non-harvested populations and species. For instance, spatial models have shown that harvesting is expected to influence the spatial synchrony of population fluctuations, both of the harvested species and its competitors, predators and prey, with implications for population extinction risk. Dispersal and interspecific interactions can cause responses to harvesting in areas and species that are not themselves harvested. Harvesting that selectively targets certain groups of individuals, either intentionally or through for example spatially biased harvesting, can amplify environmentally induced population fluctuations by biasing the population structure towards individuals that are more sensitive to environmental variation. On the other hand, harvesting can in some cases buffer populations against the density-dependent effects of harsh climatic conditions, which are probably more common than previously acknowledged. Recent advances in modeling are providing new predictions that are highly re levant under global warming and now need to be tested empirically. We discuss how knowledge of these pathways can be used to increase the sustainability of harvesting.
Optimized control of multistate quantum systems by composite pulse sequences

We introduce a technique for derivation of high-fidelity composite pulse sequences for two types of multistate quantum systems: systems with the SU(2) and Morris-Shore dynamic symmetries. For the former type, we use the Majorana decomposition to reduce the dynamics to an effective two-state system, which allows us to find the propagator analytically and use the pool of available composite pulses for two-state systems. For the latter type of multistate systems, we use the Morris-Shore decomposition, which reduces the multistate dynamics to a set of two-state systems. We present examples which demonstrate that the multistate composite sequences open a variety of possibilities for coherent control of quantum systems with multiple states.
Value-added utilization of caustic soda lye from cold caustic extraction process in the pulp mill

Three approaches were examined for the reutilization of cold caustic extraction (CCE) lye. The term CCE lye refers here to the used NaOH solution with relatively high alkali content, which could be wasted if not reused properly. The results showed that CCE lye can be effectively applied in deinking, alkaline hydrogen peroxide bleaching, and oxygen delignification processes. The CCE lye improved the physical strength of the dried sheet of pulp, as the tensile index increased by 17.9% to 40.5%, the tear index increased by 2.9% to 22.2%, and the burst index increased by 10.5% to 41.0%. The results demonstrated the feasibility of integrating the CCE process of dissolving pulp production with regular pulping and bleaching processes.
A case history of shallow sloughing within cut slopes of an irrigation canal in salt-rich clayey colluvium

An investigation and remediation of instability along cut slopes of an irrigation canal in salt-rich clayey col - luvium in southern Alberta is described. Random sloughing of the canal side slopes began to occur 2 years after con- struction over a 7500 m length of canal and was nearly continuous over a 2500 m length 3 years later. The sloughs are shallow seated and most had the appearance of a "mud" flow. Soil salinity also developed along the canal slopes due to capillarity and evaporation. Failure of the clay slopes in the cut sections is attributed to swelling, dispersion, and softening of the subgrade due to exposure of the salt-laden clays to fresh water. In contrast, 600 m of salt-rich clayey colluvium compacted as a clay liner on the canal side slopes showed no evidence of sloughing and salt loading after 9 years of service. Good soil compaction inhibited softening and slope instability in these salt-rich soils. Results from de - tailed site investigations and observations, and the interplay of soil chemistry and geology, facilitated the selection of a satisfactory method of repair. Repairs consisted of reconstructing 2500 m of canal by overexcavating the canal subgrade and replacing those soils with compacted soil.
A Review on Pre-Collision Road Accident Detection

Road accident rates are very high these days, especially for two-wheelers. Prompt medical assistance can help save lives. This system is designed to alert the nearby medical center of the incident in order to provide immediate medical attention. The proposed framework automatically learns the representation of the characteristics from the space-time characteristics of the pixel intensity. We consider the vehicle accident an unusual accident. The possibility of an accident is determined using the artificial intelligence approach and alerted by preventive measures.
Effective suppression of fluorescence light in Raman measurements using ultrafast time gated charge coupled device camera

A high level of fluorescence background signal rejection was achieved for solid and powder samples by using a combination of simple low-resolution spectrograph and ultrafast gated charge coupled device (CCD) camera. The unique timing characteristics of the CCD camera match exceptionally well to characteristics of a Ti:sapphire oscillator allowing fast gated light detection at a repetition rate of up to 110 MHz, making this approach superior in terms of the duty cycle in comparison with other time-resolved Raman techniques. The achieved temporal resolution was about 150 ps under 785 nm Ti: sapphire laser excitation. At an average excitation power up to 300 mW there was no noticeable sample damage observed. Hence, the demonstrated approach extends the capabilities of Raman spectroscopy regarding the investigation of samples with a short fluorescence lifetime. The combination of a spectrometer and a gated CCD camera allows simultaneous study of spectral and temporal characteristics of emitted light. This cap.
TheComplexity of Reasoning with Concrete Domains (Revised Version)

Description logics are knowledge representation and reasoning formalisms which represent conceptual knowledge on an abstract logical level. Concrete domains are a theoretically well-founded approach to the integration of description logic reasoning with reasoning about concrete objects such as numbers, time intervals or spatial regions. In this paper, the complexity of combined reasoning with description logics and concrete domains is investigated. We extend ALC(D), which is the basic description logic for reasoning with concrete domains, by the operators "feature agreement" and "feature disagreement". For the extended logic, called ALCF(D), an algorithm for deciding the ABox consistency problem is devised. The strategy employed by this algorithm is vital for the efficient implementation of reasoners for description logics incorporating concrete domains. Based on the algorithm, it is proved that the standard reasoning problems for both logics ALC(D) and (D) are PSpace-complete - provided that the satisfiability test of the concrete domain used is in PSpace.
Measuring the Readiness of SMEs for Eco-Innovation and Industrial Symbiosis: Development of a Screening Tool

Despite the high business, innovation and sustainability potential linked with eco-innovation and industrial symbiosis, limited implementation can be observed in small and medium enterprises (SMEs). In order to enhance the implementation of these concepts in SMEs, the main goal of this paper is to propose a screening tool to identify and evaluate SMEs’ potential for eco-innovation, with a special focus on industrial symbiosis and green business models aspects. In order to accomplish this goal, an action research was developed in two cycles: (1) development and testing of the screening prototype; and (2) improvement and scale-up of the enhanced screening tool, in close collaboration with the research partners. In addition to enabling a better understanding about their own internal processes and activities, the evaluation of the potential of 108 SMEs for eco-innovation provided them with detailed insights about how to reach the potential benefits with industrial symbiosis and green business models. Differently from the identified existing tools, the screening tool proposed in this research aims at supporting companies to understand what their potential for eco-innovation is, combining wider eco-innovation and industrial symbiosis opportunities and green business models, supplemented with a readiness evaluation to explore the existing potential.
Global financial crisis effects on volatility spillover between Mainland China and Hong Kong stock markets

The authors explore the influence of the global financial crisis on the volatility spillover between the Mainland China and Hong Kong stock markets. The data collection period is from January 04, 2002 to December 31, 2013, broken into two sub-periods: pre-crisis (January 04, 2002 to June 30, 2007) and crisis (July 01, 2007 to December 31, 2013). The authors apply asymmetric BEKK-GARCH and adopt the VAR approach as a robustness test. The results indicate that while there is no volatility spillover in the pre-crisis period, strong bi-directional volatility spillover exists in the crisis period. Meanwhile, one month 1 minute high frequency data is applied to explore intraday volatility spillover. The researchers draw three interesting conclusions: The global financial crisis enhanced the economic linkage between the Mainland China and Hong Kong stock markets; and while it did not directly influence the Mainland China market, global financial risk flowed into this region through the Hong Kong market; there exists a bi-directional daily aggregated volatility spillover, but from a microscopic view, a random volatility spillover process is concluded.
IoT Cloud Service Device-type Identification Policy Database IoT deviceIoT deviceIoT deviceIoT device IoT device Device Fingerprinting Policy Application WiFi Ethernet IoT deviceIoT device IoT device Local SOHO network IoT Gateway Internet

IoT devices are being widely deployed. But the huge variance among them in the level of security and requirements for network resources makes it unfeasible to manage IoT networks using a common generic policy. One solution to this challenge is to define policies for classes of devices based on device type. In this paper, we present AUDI, a system for quickly and effectively identifying the type of a device in an IoT network by analyzing their network communications. AUDI models the periodic communication traffic of IoT devices using an unsupervised learning method to perform identification. In contrast to prior work, AUDI operates autonomously after initial setup, learning, without human intervention nor labeled data, to identify previously unseen device types. AUDI can identify the type of a device in any mode of operation or stage of lifecycle of the device. Via systematic experiments using 33 off-the-shelf IoT devices, we show that AUDI is effective (98.2% accuracy).
One-loop Dirac neutrino mass and mixed axion-WIMP dark matter

We consider the Peccei-Quinn (PQ) mechanism as the one behind the Dirac neutrino masses when these are generated through the $d=5$ effective operator $\overline{L}\stackrel{\texttildelow{}}{H}{N}_{R}\ensuremath{\phi}$ at one-loop level, with $\ensuremath{\phi}$ being a Standard Model singlet scalar. In this setup, the PQ symmetry guarantees that the one-loop realization of such an effective operator gives the leading contribution to the Dirac neutrino masses by forbidding the contributions arising from its tree-level realizations. All the mediators in the one-loop neutrino mass diagrams can be stabilized by a remnant ${Z}_{N}$ symmetry from the PQ symmetry breaking, thus forming a dark sector besides the axion sector and leading to mixed axion-WIMP dark matter scenarios.
The Coral-Rich Devonian Limestones of the English Riviera UNESCO Global Geopark

The coral-rich limestones of the English Riviera UNESCO Global Geopark were an important component of the original definition of the Devonian System, introduced by Sedgwick and Murchison in 1840. They are, therefore, both a local highlight of the geological succession but have an important position within the history of geology. Formed in the tropical seas of the Middle Devonian, 10°S of the Equator, they also demonstrate the history of Devon in terms of Continental Drift and Plate Tectonics. Caves in these limestones provide an important record of both marine and terrestrial Pleistocene history, including some important hominin remains.
AN AUTOMATIC MODEL-BASED APPROACH FORMEASURING THE ZONA PELLUCIDA THICKNESS IN DAY FIVE HUMAN BLASTOCYSTS

As technology for human In-Vitro Fertilization (IVF) advances, techniques in analyzing the quality and optimal time for embryo transfer are also growing in sophistication. This paper focuses on an automatic method for gauging the blastocyst development stage based on the measured thickness of the Zona Pellucida (ZP) in digital embryo images of Hoffman Modulation Contrast (HMC) microscopes. Ellipsoidal models are used to capture the ZP boundaries found via edge maps. Comparison of the acquired results with that of the state of the art indicates the efficiency and accuracy of the proposed method.
