Published: February 2019

I congratulate the Journal of Robotics and Mechatronics (JRM) on the publication of its 30th anniversary issue. As one of JRM’s past Editors-in- Chief, I am extremely pleased and proud of this great achievement. JRM was the first journal dealing with robotics and mechatronics in the world when it was launched thirty years ago. Since then, the journal has made a strong impact on the robotics and mechatronics field. It has been hard for the journal to provide high quality issues for so many years. I would like to sincerely express my great respect to Mr. Hayashi, founder and former president of Fuji Technology Press Ltd.; former Editors-in-Chief Prof. Yamafuji, Prof. Fukuda, and Prof. Kaneko; the current Editor-in-Chief, Prof. Takita; and our colleagues, including the editorial board and editorial staff, for their hard work. I would also like to express my great appreciation to all the authors, reviewers, and readers for their superb contributions. This grand thirty-year achievement could not have been attained without all their contributions.
I was Editor-in-Chief for seven years ‒ volumes 19 through 25 ‒ beginning in January 2007. I enjoyed my role as Editor-in-Chief, since many young, talented researchers and engineers took part in the editorial process, and I could discuss with them how we would achieve a high-quality journal. I remember clearly how hard they worked to edit superlative volumes by proposing and organizing special issues with up-to-date topics. During that period, we had the good fortune of collaborating with the Japan Society of Mechanical Engineers (JSME). They supported us in providing committee members for our editorial board, and in collecting and reviewing the many excellent papers. I would also express my thanks to JSME for their abundant and generous support. Because of it, JRM achieved a high reputation and contributed to both academia and industry.
Today there are many relevant journals in the world. Competing with them and producing an even higher quality journal than ever before are the most critical issues in the next step of JRM’s advancement. I applaud the current editorial board members and staff and expect JRM to become the very top journal in the field. In conclusion, I hope I can celebrate with you ten and twenty years from now, again and again! Tatsuo Arai

Congratulations to the Journal of Robotics and Mechatronics (JRM) on its 30th anniversary. I would like to thank all authors and readers who have contributed to the JRM through 30 years.
The JRM started as an English-language journal published to provide articles on robot technologies to the world from Japan. It has been jointly edited by the Robotics and Mechatronics Division (RMD) of the Japan Society of Mechanical Engineers (JSME) and Fuji Technology Press Ltd. Five years ago, when the English-language journal of the JSME was reorganized, the JRM also underwent some changes, and it has since been issued under the editorial direction of Fuji Technology Press Ltd. Immediately after the reorganization, beginning with Vol.26, I was appointed Editor-in-Chief. Now, as five years have passed, the next Editor-in-Chief will take over from Vol.31. Over these five years, the number of submissions and their quality have been our major concern, as we have been seeking to register the JRM with the Science Citation Index (SCI). To achieve this goal, we have published special issues on the robot technologies required as the field has progressed as well as on the mechatronics technologies that underlie them.
The JRM plans to continue providing the world with information on robot technologies, so please keep reading it and submitting your articles to it on a regular basis.

LHC searches motivated by recent $B$-anomalies
Authors: Faroughy Darius A. 
Published: February 2019

We discuss the physics case for the LHC motivated by the
BB-physics
anomalies. After correlating semi-tauonic BB
decays to di-tau production at the LHC, and discussing the possible
models solving the BB-anomalies,
we show how existing LHC data in \tau\bar\tauττ‾
tails exclude most beyond the SM scenarios except for a handful of
leptoquark (LQ) models. We analyze the impact of LHC searches for some
of these LQ solutions using current data. In particular, we focus on the
well known U_1U1
vector LQ as well as the GUT-inspired scalar LQs,
R_2R2
and S_3S3.
By exploiting the complementarity between di-tau searches and the lepton
flavor violating decays B\to K\mu\tauB→Kμτ
and \tau\to\mu\phiτ→μϕ
we argue that these model can be cornered by the LHC, Belle II and LHCb
in the near future.

Hydraulic scale modelling of the rating curve for a gauging station with challenging geometry
Authors: Pedersen Øyvind , Aberle Jochen , Rüther Nils 
Published: February 2019

Abstract
Direct discharge measurements during flood events can be challenging from a technical as well as from a safety point of view. Therefore, flood discharges are often estimated by extrapolating a rating curve. Extrapolations far outside the range of the directly measured discharges are common, although the associated errors can be large. In this article, a novel method to determine suitable stage measurement locations and derive rating curves using a hydraulic scale model is presented. A hydraulic scale model for a natural gauging station site is produced with a computer numerical control technique, making a detailed representation of the prototype topography and bathymetry. The site is characterized by a complex geometry, and the results of the scale model study reveal that the current location of stage measurement is not suitable for determining the rating curve for high flows. The scale model is used to identify potential locations for future stage measurements, and a flood rating curve is constructed based on field measurements for low flows and scale model data for high flows. The study shows how hydraulic scale modelling can be used to provide more reliable rating curves for large discharges and evaluate new or existing gauging stations located at sites with challenging measurement conditions.
Nanofibers for textile waste water management
Authors: Paneysar Joginder singh , Sawant Snehal , Ip Meng Hei , Bhullar Sukhwinder kaur , Barton Stephen , Ambre Premlata , Coutinho Evans 
Published: February 2019

Abstract
Currently, textile wastewater management focuses on dye removal efficiency and operating costs. Dual responsive polymers are choice materials because they can extract diverse organic compounds from water at their phase transition point. They are copolymers of the acrylamide class, and have been fully characterized by FT-IR, 1H-NMR, DSC, GPC and surface area analysis. Of the five dual responsive polymers, the copolymer of NIPAAM and DMAEMA (CoP-1) offers the best extraction of acidic and basic dyes from wastewater. All copolymers investigated can achieve better than 90% dye removal when used at 4 mg/ml concentration. This dye-scavenging efficiency increases to almost 99% at 3 mg/ml, on conversion of the copolymers to nanofibers in 300 to 500 nm size. Langmuir and Freundlich isotherms were constructed to study the mechanism of dye adsorption. The nanofibers have been shown to be reusable for removal of dyes from water, suggesting that such systems may add benefit to current dye removal methods from textile industry wastewater.
Development of statistical predictive models for estimating the methane yield of Italian municipal sludges from chemical composition: a preliminary study
Authors: Catenacci A. , Azzellino A. , Malpei F. 
Published: February 2019

Abstract
The biochemical methane potential (BMP) of primary and biological sludge varies in a wide range, mostly depending on location, sewer characteristics, wastewater treatment plant design and operating conditions. BMP tests are useful to verify the performance of a full scale digester, but they are not yet a common procedure in the operation of most Italian facilities because of cost and test duration. Changes in the composition of sewage sludge can lead to a high variation of biogas production. Aimed at developing BMP predictive models based on low cost and fast analyses, this study investigated the chemical composition of 20 sludge samples by means of principal component and multiple linear regression analyses. Three preliminary predictive models were developed based on soluble organic nitrogen, volatile solids, carbohydrates, proteins, lipids and an operational parameter, the sludge retention time: the explained variance and the standard errors of prediction of BMP are in the range 77–81% and 21–34 NmLCH4·gVS−1, respectively. Models were evaluated on five additional samples: errors ranged 2–15% for four samples and about 54% for one sample, collected from a peculiar facility. Further data and variables describing the operation mode of the waterline would certainly improve the reliability and robustness of the models.

Published: February 2019

Abstract
Results of an extended survey on the production and quality of sewage sludge produced in Italy are herewith reported and discussed. Data are relevant to 2015. They were provided by 84 Italian water utilities responsible for municipal wastewater treatment serving approximately 35 million persons. Total production was estimated at about 395,000 t dry solids/year, of which 9.9% is used in agriculture without further treatments, 26.4% is sent to external plants for compost production, 5.6% is sent to external plant for production of a soil conditioner called ‘chalk of defecation’, 17.2% is disposed to landfill, and 5.9% is sent to incineration or co-incineration plants. The rest (35%) is sent to external sludge centres for further treatments (manly chemical and physical processes) before recovery/disposal. Regarding chemical characterization the following parameters were investigated: TOC, total nitrogen, total phosphorus, potassium, arsenic, cadmium, copper, nickel, lead, zinc, mercury, total chromium, chromium VI, selenium, hydrocarbons C10–C40, sum of polycyclic aromatic hydrocarbons, sum of polychlorinated biphenyls, sum of polychlorinated dibenzo-p-dioxins/dibenzo-p-furanes (toxic equivalent) salmonella, faecal coliforms, sulphur, sum of absorbable halogenated organic compounds, nonylphenol and nonylphenolethoxylates with one or two ethoxy groups, and di(2-ethylhexyl)phthalate. All the parameters showed that the quality of Italian sewage sludge is consistent with a typical sludge in Europe, Asia and America and the maximum concentrations of pollutants are well below the fixed standards of the European Directive 86/278 and the third draft of the European Commission's Working Document on Sludge.
Electrochemical degradation of naproxen from water by anodic oxidation with multiwall carbon nanotubes glassy carbon electrode
Authors: Díaz Eva , Stożek Sonia , Patiño Yolanda , Ordóñez Salvador 
Published: February 2019

AbstractNaproxen (NPX) degradation was investigated by anodic oxidation both at constant potential and by cyclic voltammetry, using this last technique for optimizing reaction conditions and catalyst properties. Three multiwall carbon nanotubes (MWCNTs)-promoted electrodes were used (MWCNT, MWCNT-COOH and MWCNT-NH2) and a two steps oxidation process was observed in all the cases. At the optimized conditions (volume of MWCNT = 15 μL), the influence of the scan rate indicates the diffusion–adsorption control of the process. Likewise, the kinetic study of NPX degradation at fix potential, considering two different stirring speeds (250 and 500 rpm), indicates that degradation rate increases with the stirring speed. After 20 h, NPX is degraded even an 82.5%, whereas the mineralization reaches almost 70%, as it was obtained from total organic carbon analysis. The pH effect was also analysed, in the range 5–11, observing a positive effect at low pH. Concerning the surface chemistry of the electrode, MWCNT-NH2, with the highest isoelectric point (4.70), is the most promising material due to the improved interactions with the reactant. From these observations, a pathway is proposed, which includes two steps of electrochemical oxidation followed by subsequent oxidation steps, until mineralization of the NPX, attributed mainly to active chlorine species and ·OH.
Synthesis and evaluation of activated carbon/nanoclay/ thiolated graphene oxide nanocomposite for lead(II) removal from aqueous solution
Authors: Mojoudi Fatemeh , Hamidian Amir Hossein , Zhang Yu , Yang Min 
Published: February 2019

Abstract
Novel porous nanocomposite (AC/NC/TGO) was successfully synthesized through the composition of activated carbon, nanoclay and graphene oxide as a Pb(II) adsorbent for the treatment of contaminated aqueous environment. The physicochemical properties and morphology of AC/NC/TGO were examined by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy and nitrogen adsorption-desorption techniques. Results showed Pb(II) adsorption on the AC/NC/TGO was rapid in the first 20 min and reached equilibrium in 40 min. Kinetic studies showed significant fit to the pseudo second order kinetic model (R2 ≥ 0.9965) giving an equilibrium rate constant (K2) of 0.0017 g mg−1 min−1 for Pb(II) loaded. The experimental adsorption data were better fitted with the Langmuir isotherm model than with the Freundlich isotherm model. Prepared nanocomposite exhibited high values of Brunauer–Emmett–Teller (BET) surface area of 1,296 m2 g−1 and total pore volume of 1.01 cm3 g−1. Maximum adsorption capacity (Qmax = 208 mg g−1) and a relatively high adsorption rate was achieved at pH 5.0 using an adsorbent dose of 0.5 g L−1 and an initial lead concentration of 50 mg L−1. High adsorption capacity, reusability, fast kinetics and simple synthesis method indicate that prepared nanocomposite can be suggested as a high-performance adsorbent for Pb(II) removal from polluted water.
Preparation and Improved Capacitive Behavior of NiO/TiO2 Nanocomposites as Electrode Material for Supercapacitor
Authors: Anandhi Palani , Kumar Veerabadran Jawahar Senthil , Harikrishnan Santhanam 
Published: February 2019

Background:
Of late, supercapacitors have been drawing great attention over other rechargeable
energy storage devices. More efforts are made on the electrode materials of the supercapacitors,
in order to improve the specific capacitance and energy density. Based on the past literature,
it was stated that pure TiO2 (as electrode material) could promote faradaic reaction to a limited extent
due to its low electronic conductivity. Further, this low conductivity could hinder the ion transfer
process between electrolyte and electrode during intercalation and de-intercalation, resulting in poor
energy density. Hence, it is essential to incorporate high electronic conductivity material into TiO2,
for improving the electrochemical performance.

Objective:
In the present study, the preparation and electrochemical performance of NiO/TiO2 nanocomposites
as an electrode material for supercapacitor were extensively studied.

Methods:
NiO/TiO2 nanocomposites were synthesized by sol-gel method. The as-prepared nanocomposites
were characterized by high-resolution TEM, field emission SEM and XRD. The electrochemical
behaviors of the electrode using nanocomposites were assessed by means of cyclic voltammetry (CV)
and galvanostatic charge-discharge tests.

Results:
The maximum specific capacitance of the nanocomposites based electrode witnessed through
CV test was 405 F g-1 at the scan rate of 5 mV s-1 in 1M Na2SO4 electrolyte. The capacitance retention
after 5000 charge-discharge cycles was estimated as 92.32%. The energy and power densities at current
density of 1 A g-1 were found to be 5.67 Wh kg-1 and 210.52 W kg-1, respectively.

Conclusion:
NiO/TiO2 nanocomposites synthesized via sol-gel technique appeared to be flake-like
structure. NiO incorporated into TiO2 increased higher electronic conductivity while comparing to
pure TiO2. Also, an introduction of NiO into TiO2 improved the specific capacitance, power density,
energy density and cycle stability. Due to these facts, combining NiO with TiO2 could be considered
to be an efficient way of enhancing the electrochemical performance of electrodes of the supercapacitor.
Delay Aware and Lifetime Enhanced Sectoring (DALES) Routing Protocol for Heterogeneous Wireless Sensor Network
Authors: Dutt Suniti , Shandil Nikita , Agrawal Sunil , Vig Renu 
Published: February 2019

Background & Objective:
Wireless communication technologies are continually growing
in diverse areas, which are providing unexampled research opportunities in the areas of networking.
One such speedily developing orbit is Wireless Sensor Networks. The ability of these networks to
operate in human-inaccessible terrains and hazardous locations have attracted a lot of research for
addressing various difficulties presented by these networks at different layers. Routing is a challenge
due to the unpredictable topology of WSNs. Further, there exists a wide range of applications employing
WSNs which operate in a hostile environment. The presence of a hostile environment literally
means that the operating devices fail quite frequently and it is practically infeasible to repair them
and replenish their energy resources. Further, many real-time applications of WSN do not tolerate
any latency in the network. In general, designing an energy-efficient routing scheme that can tradeoff
between different design metrics, like delay, is a crucial issue in WSNs. Due to a great deal of
speculations and future prognoses regarding the Internet of Things, WSN design faces various design
goals that often conflict with each other, such as short delay, high throughput, minimal energy consumption,
and low cost. Network design for futuristic applications must consider many factors for
achieving trade-offs among multiple objectives to achieve optimal performance for network.

Methods:
This paper proposes a routing protocol named Delay Aware and Lifetime Enhanced Sectoring
(DALES) for joint optimization of lifetime and delay in a heterogeneous WSN. It alters the
CH selection process by sectoring the WSN field, barring certain nodes from participating in clustering
and selecting an optimal number of CHs by use of modified probability equations.

Conclusion:
Simulation results establish that proposed solution ameliorates in terms of network lifetime
and delay as compared to other routing protocols.
Sum-Rate Optimization Constrained by Consumed Power for Multi- Antenna Non-Regenerative Relay Network
Authors: Alibeigi Maryam , Moghaddam Shahriar S. 
Published: February 2019

Background & Objective:
This paper considers a multi-pair wireless network, which communicates
peer-to-peer using some multi-antenna amplify-and-forward relays. Maximizing the throughput
supposing that the total relay nodes’ power consumption is constrained, is the main objective of this
investigation. We prove that finding the beamforming matrix is not a convex problem.

Methods:
Therefore, by using a semidefinite relaxation technique we find a semidefinite programming
problem. Moreover, we propose a novel algorithm for maximizing the total signal to the total
leakage ratio. Numerical analyses show the effectiveness of the proposed algorithm which offers
higher throughput compared to the existing total leakage minimization algorithm, with much less
complexity.

Results and Conclusion:
Furthermore, the effect of different parameters such as, the number of relays,
the number of antennas in each relay, the number of transmitter/receiver pairs and uplink and
downlink channel gains are investigated.
One Pot Synthesis of Biscoumarins and Pyranocoumarins by Coconut Juice as a Natural Catalyst
Authors: Halder Bipasa , Maity Himadri S. , Nag Ahindra 
Published: February 2019

Background:
The conception of ‘Green chemistry’ is the much inventive chemistry which
is potent and more environmentally benign. It is notable that many organic reactions take place in
conventional organic solvents, known as volatile organic compounds. Being concerned about the environmental
impact, we report a promoting medium, coconut juice (ACC) for one-pot synthesis of
biscoumarins and pyranocoumarins which is safe, harmless, green and environmentally benign.

Methods and Results:
Substituted biscoumarins have been achieved by the reaction of biscoumarin
and substituted aromatic aldehydes in presence of ACC which acts as a green catalyst cum solvent.
Each reaction showed good to excellent yield in presence of both electron donating as well as electron
withdrawing group on aromatic aldehyde without formation of any by-products. Similarly, pyranocoumarins
have been achieved by the reaction of biscoumarin, substituted aromatic aldehydes, active
methylene nitrile in presence of ACC. All the reactions proceed smoothly and gave higher yields
in case of malononitrile in comparison of ethyl-2-cyanoacetate.

Conclusion:
A simple, eco-friendly and novel procedure was demonstrated for the synthesis of biscoumarins
and pyranocoumarins using natural feedstock coconut juice. The major importance of using
ACC juice is higher yields, no work-up and no column chromatography.
