A mechanical model of the half-sarcomere which includes the contribution of titin
Authors: Pertici  , Caremani M. , Reconditi M. 
Published: October 2018

ABSTRACTThe evidence, in both resting and active muscle, for the presence of an I-band spring element like titin that anchors the Z line to the end of the thick filament did not yet produce a proper theoretical treatment in a complete model of the half-sarcomere. The textbook model developed by A.F. Huxley and his collaborators in 1981, which provides that the half-sarcomere compliance is due to the contribution of the compliances of the thin and thick filaments and actin-attached myosin motors, predicts that at any sarcomere length the absence of attached motors results in an infinite half-sarcomere compliance, in contrast with the observations. Growing evidence for the presence of a titin-like I-band spring urges the 1981 model to be implemented to include the contribution of this element in the mechanical model of the half-sarcomere. The model described here represents a tool for the interpretation of measurements of half-sarcomere compliance at long sarcomere lengths and for investigations of the possible role of titin as the mechano-sensor in thick filament regulation.
The semio-logic of financial accounting
Authors: Hayoun Shaul 
Published: October 2018

Purpose
The purpose of this paper is to contribute to the discussion on the non-essence of accounting by focusing on financial accounting’s distinct technology: financial statements. Complementing the genealogical perspective on accounting’s changing socio-historical settings, it proposes a semiotic perspective on the accounting statement.

Design/methodology/approach
The paper takes an interdisciplinary approach in the theoretical framing of IFRS recognition and measurement principles that underlie the statement of financial position. It mobilises Saussure and Barthes’ sign theory – semiology, as it provides a meaningful delineation of financial accounting, bringing out its distinct numerical-linguistic knowledge-construction operation.

Findings
In addition to the justification of employing semiology as a parent discipline for accounting, it is shown how IASB’s recognition and measurement procedures manifest the interrelated non-essentialist semiological principles of reciprocal articulation and value constellation. Accounting entries (“expression”) are not representations of pre-existing economic resources (“content”), but rather both are mutually constituted by delimiting the resource/asset from its broader category. Such judgment-based articulation results with value constellations, where asset value is merely a relational product of other values.

Originality/value
To the long-established critique that accounting has no essence, the paper adds a formulation of a non-essentialist semiotic logic: the financial statement’s semio-logic. It further sheds light on the role of such logic as an epistemological presupposition to the accounting – society reciprocity, where accounting is a malleable product of, and is used to exert power over, its social surroundings.
A three-phase linear load flow solution based on loop-analysis theory for distribution system
Authors: Li Hong wei , Zhu Hairong , Pan Li 
Published: October 2018

Purpose
To realize the operation optimizing of today’s distribution power system (DPS), like economic dispatch, contingency analysis, and reliability and security assessment etc., it is beneficial and indispensable that a faster linear load flow method is adopted with a reasonable accuracy. Considering the high R/X branch ratios and unbalanced features of DPS, the purpose of this paper is to propose a faster and non-iterative linear load flow solution for DPS.

Design/methodology/approach
Based on complex function theory, the derivations of the injection current linear approximation have been proposed for the balanced and the single-, double- and three-phase unbalanced loads of DPS on complex plane. Then, a simple and direct linear load flow has been developed with loop-analysis theory and node-branch incidence matrix.

Findings
The methodology is appropriate for balanced and single-, double- and three-phase hybrid distribution system with different load models. It provides a fast and robust load flow method with a satisfactory accuracy to handle the problems of DPS whenever the load flow solutions are required.

Research limitations/implications
The distributed generators (DGs) with unity or fixed power factors can be easily included. But the power and voltage nodes cannot be dealt with directly and need to be further studied.

Originality/value
By combining the current linear approximation with the loop theory-based method, a new linear load flow method for DPS has been proposed. The method is valid and acute enough for balanced and unbalanced systems and has no convergent problems.
Dynamic sliding mode position control of induction motors based load torque compensation using adaptive state observer
Authors: Karami-Mollaee Ali , Tirandaz Hamed , Barambones Oscar 
Published: October 2018

Purpose
The purpose of this paper is position control scheme for a servo induction motor (SIM) with uncertainty has been designed using a new observer issue and a dynamic sliding mode control (DSMC).

Design/methodology/approach
In DSMC, the chattering is removed due to the integrator (or a low-pass filter) which is placed before the input control of the plant. However, in DSMC, the augmented system has one dimension bigger than the actual system (if integrator is used) and then, the plant model should be completely known. To solve this problem in SIM, the use of a new adaptive state observer (ASO) is proposed.

Findings
The advantage of the proposed approach is to maintain the system controlled under the external load torque variations. Then, the load variations do not affect the motor positioning. Moreover, it is demonstrated that the observer error converges to zero based on the Lyapunov stability theory.

Originality/value
The knowledge of the upper bound for the system uncertainty is not necessary in an adaptive state observer, which is important in practical implementation. Simulation results are presented to demonstrate the performance of the proposed approach.

Authors: Bao Bocheng , Luo Jiaoyan , Bao Han , Xu Quan , Hu Yihua , Chen Mo 
Published: October 2018

Purpose
The purpose of this paper is to construct a proportion-integral-type (PI-type) memristor, which is different from that of the previous memristor emulator, but the constructing memristive chaotic circuit possesses line equilibrium, leading to the emergence of the initial conditions-related dynamical behaviors.

Design/methodology/approach
This paper presents a PI-type memristor emulator-based canonical Chua’s chaotic circuit. With the established mathematical model, the stability region for the line equilibrium is derived, which mainly consists of stable and unstable regions, leading to the emergence of bi-stability because of the appearance of a memristor. Initial conditions-related dynamical behaviors are investigated by some numerically simulated methods, such as phase plane orbit, bifurcation diagram, Lyapunov exponent spectrum, basin of the attraction and 0-1 test. Additionally, PSIM circuit simulations are executed and the seized results validate complex dynamical behaviors in the proposed memristive circuit.

Findings
The system exhibits the bi-stability phenomenon and demonstrates complex initial conditions-related bifurcation behaviors with the variation of system parameters, which leads to the occurrence of the hyperchaos, chaos, quasi-periodic and period behaviors in the proposed circuit.

Originality/value
These memristor emulators are simple and easy to physically fabricate, which have been increasingly used for experimentally demonstrating some interesting and striking dynamical behaviors in the memristor-based circuits and systems.

Authors: Rahimi Alireza , Kasaeipoor Abbas , Hasani Malekshah Emad , Kolsi Lioua 
Published: October 2018

Purpose
This paper aims to perform the lattice Boltzmann simulation of natural convection heat transfer in cavities included with active hot and cold walls at the side walls and internal hot and cold obstacles.

Design/methodology/approach
The cavity is filled with double wall carbon nanotubes (DWCNTs)-water nanofluid. Different approaches such as local and total entropy generation, local and average Nusselt number and heatline visualization are used to analyze the natural convection heat transfer. The cavity is filled with DWCNTs-water nanofluid and the thermal conductivity and dynamic viscosity are measured experimentally at different solid volume fractions of 0.01 per cent, 0.02 per cent, 0.05 per cent, 0.1 per cent, 0.2 per cent and 0.5 per cent and at a temperature range of 300 to 340 (K).

Findings
Two sets of correlations for these parameters based on temperature and solid volume fraction are developed and used in the numerical simulations. The influences of different governing parameters such as Rayleigh number, solid volume fraction and different arrangements of active walls on the fluid flow, heat transfer and entropy generation are presented, comprehensively. It is found that the different arrangements of active walls have pronounced influence on the flow structure and heat transfer performance. Furthermore, the Nusselt number has direct relationship with Rayleigh number and solid volume fraction. On the other hand, the total entropy generation has direct and reverse relationship with Rayleigh number and solid volume fraction, respectively.

Originality/value
The originality of this work is to analyze the two-dimensional natural convection using lattice Boltzmann method and different approaches such as entropy generation and heatline visualization.

City of Kampung: risk and resilience in the urban communities of Surabaya, Indonesia
Authors: Shirleyana Shirleyana , Hawken Scott , Sunindijo Riza Yosia 
Published: October 2018

Purpose
The purpose of this paper is to bring a new perspective on the meaning of resilience in Indonesia’s main urban settlement type, known as kampung. The paper reviews kampung in major urban centres in Indonesia, but focuses on a case study of Surabaya, Indonesia’s second largest city. Despite effectively accommodating the majority of Surabaya’s population, kampung inhabitants are stigmatised and kampung are viewed as slum-like habitats. Such a pejorative view neglects to consider the importance of kampung and ignores their inherent and potential resilience. It is important to study both the risks and resilience of kampung so that they can be developed to address social, economic and environmental vulnerabilities in Southeast Asian cities.

Design/methodology/approach
A comprehensive literature review was conducted to identify the risks and resilience of kampung. Key themes were mapped from the literature and used to construct a framework for understanding and enhancing resilience within this distinctive vernacular settlement type. In addition, a place-based approach constructed from remote sensing and field studies provide a deeper understanding of the structure of this urban settlement type.

Findings
Kampung play an important role in housing the majority of Surabaya’s population and are an intrinsic part of the city’s urban structure. The characteristics and conditions of kampung vary throughout Indonesia. Surabaya has a variety of kampung types which demonstrates distinctive forms of both risk and resilience. This research finds that there are many positive dimensions of kampung and that this vital form of settlement is well suited to support the growth and sustainability of Southeast Asia’s emerging megacities.

Research limitations/implications
This paper evaluates the current state of knowledge on risk and resilience of kampung within Surabaya. To gain a clearer understanding of why kampung are resilient, long-term field work and deeper analysis of kampung, in particular the social and physical structures, are needed.

Practical implications
Planning for high-density urban development needs to integrate kampung as a part of existing and new urban settlements to accommodate diverse populations.

Originality/value
This paper demonstrates that knowledge on kampung resilience is relevant to the adaptation of existing urban settlements and the future development of new urban settlements. This paper contributes a clearer understanding of why kampung in Surabaya are not slums and establishes a framework that supports the development of kampung as a resilient and functional settlement type in current and future urban developments. Considering the large and rapidly growing populations who depend on kampung in the Southeast Asian region, this research is of considerable significance.
A new pose estimation method for non-cooperative spacecraft based on point cloud
Authors: Chen Zhiming , Li Lei , Wu Yunhua , Hua Bing , Niu Kang 
Published: October 2018

Purpose
On-orbit service technology is one of the key technologies of space manipulation activities such as spacecraft life extension, fault spacecraft capture, on-orbit debris removal and so on. It is known that the failure satellites, space debris and enemy spacecrafts in space are almost all non-cooperative targets. Relatively accurate pose estimation is critical to spatial operations, but also a recognized technical difficulty because of the undefined prior information of non-cooperative targets. With the rapid development of laser radar, the application of laser scanning equipment is increasing in the measurement of non-cooperative targets. It is necessary to research a new pose estimation method for non-cooperative targets based on 3D point cloud. The paper aims to discuss these issues.

Design/methodology/approach
In this paper, a method based on the inherent characteristics of a spacecraft is proposed for estimating the pose (position and attitude) of the spatial non-cooperative target. First, we need to preprocess the obtained point cloud to reduce noise and improve the quality of data. Second, according to the features of the satellite, a recognition system used for non-cooperative measurement is designed. The components which are common in the configuration of satellite are chosen as the recognized object. Finally, based on the identified object, the ICP algorithm is used to calculate the pose between two frames of point cloud in different times to finish pose estimation.

Findings
The new method enhances the matching speed and improves the accuracy of pose estimation compared with traditional methods by reducing the number of matching points. The recognition of components on non-cooperative spacecraft directly contributes to the space docking, on-orbit capture and relative navigation.

Research limitations/implications
Limited to the measurement distance of the laser radar, this paper considers the pose estimation for non-cooperative spacecraft in the close range.

Practical implications
The pose estimation method for non-cooperative spacecraft in this paper is mainly applied to close proximity space operations such as final rendezvous phase of spacecraft or ultra-close approaching phase of target capture. The system can recognize components needed to be capture and provide the relative pose of non-cooperative spacecraft. The method in this paper is more robust compared with the traditional single component recognition method and overall matching method when scanning of laser radar is not complete or the components are blocked.

Originality/value
This paper introduces a new pose estimation method for non-cooperative spacecraft based on point cloud. The experimental results show that the proposed method can effectively identify the features of non-cooperative targets and track their position and attitude. The method is robust to the noise and greatly improves the speed of pose estimation while guarantee the accuracy.

Authors: Sun Francis 
Published: October 2018

PurposeThis paper aims to take an economic transaction governance approach to explore the determinants for the effectiveness of the social practice of client entertainment in facilitating business relationships in China.Design/methodology/approachThe analysis is based on a broader theoretical framework which posits that exchange relationships are regulated through a combination of market, legal and social relational mechanisms and client entertainment plays a governance role by reinforcing social relational governance to regulate the behaviors of economic actors. Upon this framework, this study proposes that the social behavioral features of client entertainment affect the effectiveness of client entertainment in facilitating exchange relationships and that time moderates such effects. These hypotheses were tested on survey data collected from a sample of Chinese sales managers.FindingsEmpirical results indicate that the effectiveness of client entertainment in facilitating exchange relationships is associated with its social behavioral features that could reinforce social relational governance, including intensity (i.e. value and frequency) and format (i.e. intimacy and observability) of entertainment activities, and the time factor plays a moderating role.Practical implicationsThis study can potentially help policymakers to regulate client entertainment, and business practitioners to manage entertainment spending, more effectively and efficiently without causing legal and ethical problems.Originality/valueThis is the first study that takes an economic transaction governance perspective to directly explore how the social practice of client entertainment plays a constructive role in China’s economic life and what factors affect its effectiveness in playing such a role. It offers guidelines for policymakers, business managers and future research to manage and study this practice.
