Capabilities for the internet of things enabled product-service system business models

ABSTRACT The Internet of things (IoT) transforms how businesses operate, create, and deliver products and services. Despite increasing interest in IoT business models, knowledge of the capabilities needed to implement them remains vague. The objective of this paper is to investigate patterns found in 21 empirical tested cases covering several industries. This paper identifies the most common capabilities (connectivity, data management and storage, monitoring, data analytics, control, operations management, maintenance, communication, applications, and security) in an IoT-Product Service System (PSS). Industry practitioners can use this information to visualise linkages between their intended business model and capabilities when developing IoT-PSSs.

Experiments on low velocity cooling of high conductivity substrates

Experiments are reported on low velocity cooling of a heater-on-substrate geometry for high conductivity substrate materials. Four different substrate materials were studied: 1) aluminum 6061-T6; 2) aluminum nitride; 3) alumina; 4) FR-4. The effects of combined buoyancy and forced air flow, geometric orientation, substrate size, thermal conductivity, and emittance on heat transfer are evaluated. Results define the performance of the substrates and the limits of conjugate mixed convection for horizontal substrates, and of orientation effects for substrates tilted from buoyancy-opposing to buoyancy-assisting orientations. An analytical approximation is described that predicts the experimental data with good accuracy over broad parameter ranges.
Septicemia Due to Listeria monocytogenes Infection: A Systematic Review and Meta-Analysis.

Listeriosis is a rare bacterial infection associated with foodborne illness that can result in septicemia, a serious acute outcome. Sepsis is responsible for one in three deaths during hospitalization. The objective of this study was to conduct a systematic review and meta-analysis to estimate the proportion of Listeria monocytogenes infections resulting in septicemia. PubMed, Embase, Scopus, and Web of Science were searched from January 1, 2000, to April 1, 2018, for epidemiological studies that assessed studies focusing on L. monocytogenes infections with the outcome of septicemia. Articles in English, Spanish, and Portuguese using case-control, cohort, or outbreak studies reporting measures of association between L. monocytogenes and septicemia were included. Bias and heterogeneity were assessed using univariate meta-regression for region, sample size, study design, and report method. Nineteen articles were eligible for inclusion post-screening, the majority of which were conducted in Europe (n = 15); utilized a retrospective cohort design (n = 16); and collected data via routine or laboratory surveillance methods (n = 10). Prevalence of sepsis ranged from 4.2% to 100% among study populations of 6 to 1374 individuals. Overall, the proportion of listeriosis cases that developed sepsis was 46% (95% confidence interval [CI] 31.0-61.0%); for neonatal cases, 21.3% (95% CI 11.0-31.6%); and for maternal and neonatal cases, 18.8% (95% CI 10.7-26.8%). The heterogeneity was high for overall and group meta-analyses, but it could not be explained by the subanalyses for the overall proportion, whereas for neonatal, and neonatal and maternal cases combined, China had a significantly lower proportion than Europe and the United States. Septicemia following L. monocytogenes infection is a severe acute complication with 31-61% rate found overall; however, greater delineation of demographic data is needed to determine important risk factors. Future research should aim to address the gaps in knowledge in the long-term outcomes of sepsis from L. monocytogenes infection, and whether these outcomes differ from those due to other infections.
Spatially resolved measurements of ballistic and total transmission in microscale tissue samples from 450 nm to 1624 nm

: We built a simple and versatile setup to measure tissue ballistic and total transmission with customizable wavelength range, spatial resolution, and sample sizes. We performed ballistic transmission and total transmission measurements of overlying structures from biological samples ex vivo . We obtained spatially resolved transmission maps to reveal transmission heterogeneity from five microscale tissue samples: Danionella skin, mouse skull bone, mosquito cuticle, wasp cuticle, and rat dura over a wide spectral range from 450 nm to 1624 nm at a spatial resolution of ∼ 25 µ m for ballistic transmission measurements and ∼ 50 µ m for total transmission measurements. We expect our method can be straightforwardly applied to measuring the transmission of other samples. The measurement results will be valuable for multiphoton microscopy. The total transmission of a sample is important for the collection of multiphoton excited fluorescence and the assessment of laser-induced sample heating. The ballistic transmission determines the excitation power at the focus and hence the fluorescence signal generation. Therefore, knowledge of ballistic transmission, total transmission, and transmission heterogeneity of overlying structures of animals and organs are essential to determine the optimal excitation wavelength and fluorophores for non-invasive multiphoton microscopy. We further compare the ex-vivo measurements in this study to the in-vivo and ex-vivo measurements reported in a previous study in the case of mouse skull. In this study, the mean and standard deviation of the mouse skull effective attenuation length (EAL) at 1300 nm and 1624 of the optical transmission from the overlying structures of samples is an essential parameter when performing MPM. We built a versatile tissue spectrometer that can be straightforwardly applied to measure spatially resolved ballistic and total transmission of biological specimens in a customizable setup for different wavelengths, spatial resolutions, and sample sizes. We measured ballistic transmission and total transmission of overlying structures from biological samples in microscale ex-vivo . We reported the ballistic and total transmission map to reveal transmission heterogeneity from five tissue samples: Danionella skin, mouse skull bone, mosquito cuticle, wasp cuticle, and rat dura over a wide spectral range from 450 nm to 1624 nm at a spatial resolution of ∼ 25 µ m for ballistic transmission and ∼ 50 µ m for total transmission. These results will be valuable for MPM, where knowing the ballistic transmission, total transmission, and transmission heterogeneity of the sample are necessary to determine the optimal excitation wavelength and the fluorophores.
Towards a theory of submarine mast detection

Complex radar targets are often modelled as a number of individual scattering elements randomly distributed throughout the spatial region containing the targets. A common assumption in this case requires independent scatterers with a uniformly distributed phase. Asymptotically, this leads to a Gaussian distribution of the scattered signal or a Rayleigh distributed Radar Cross Section (RCS). However, a class of problems exists where the target must be modelled as a random scatterer and the number of scatterers is not large enough to safely apply the Large Numbers Theorem. One such problem is the detection of submarine masts in a clutter. Here we consider an alternative approach to describe the statistics of the RCS based on deterministic target response modelling and a statistical description of the target movement.
Effects on scan blindness of full and partial crosswalls between notch antenna array unit cells

Endfire slotline notch antennas are attractive candidates for use as printed antenna array elements due to their broad bandwidth capabilities. These elements can be difficult to array because scan blindnesses may occur unexpectedly. One class of these blindnesses, an E-plane scan blindness, was explored by Schaubert and Aas (see IEEE Antennas Propagat. Soc. Symp. Dig., p.1612-1615, 1993). The referenced article gives graphs for the predicted blindness angle. A trough is formed by the metallized dielectrics and the ground plane. One possible explanation of this phenomenon is that the interelement phasing required to steer the beam to the blind angle excites a surface wave, which propagates down the trough. All of the power, instead of radiating into space, is guided across the array face, causing the blindness. This paper presents simulated results of the effects of blockading the trough with an electrically conducting cross wall (a wall perpendicular to both the metallized dielectric and the array face, as shown) or using portions thereof. The full cross wall is shown to eliminate the blindness. Interesting results which arise when partial walls are placed between unit cells are also presented. One set of results suggests a new modification to the notch array one in which the active element pattern provides far out sidelobe suppression.
A gait recognition method using HMM

New biometrics identification methods, including person identification using a walk characteristic (gait recognition) is attracting attention. In this paper, an identification method on gait recognition is proposed. In the proposed method, outlines of person are represented by P-style Fourier descriptions, and these time-serial walking characteristics use HMM. It is shown that the proposed method brings the high rate of identification and is effective in indoor environment with simulation results.

Carbon Footprint Inventory, Estimation and Analysis System in a RC Building Materials

The construction industry is one part of economic development critical to a nation’s infrastructure. However, there is significant man-made “Greenhouse Gas (GHG)” generated during the construction industry’s any Life Cycle (LC). We tailor actions to suit local circumstance and made a systematically preliminary investigation of an inventory, estimation and analysis system currently available in estimation of carbon footprints of an ordinary RC building in Taiwan. There are about 60% of carbon footprints derived from production or usage of high carbon emission building material steel bars.
Antiviral Potential of Selected Medicinal Herbs and Their Isolated Natural Products

Viruses are responsible for a variety of human pathogenesis. Owing to the enhancement of the world population, global travel, and rapid urbanization, and infectious outbreaks, a critical threat has been generated to public health, as preventive vaccines and antiviral therapy are not available. Herbal medicines and refined natural products have resources for the development of novel antiviral drugs. These natural agents have shed light on preventive vaccine development and antiviral therapies. This review intends to discuss the antiviral activities of plant extracts and some isolated plant natural products based on mainly preclinical (in vitro and in vivo) studies. Twenty medicinal herbs were selected for the discussion, and those are commonly recognized antiviral medicinal plants in Ayurveda (Zingiber officinale, Caesalpinia bonducella, Allium sativum, Glycyrrhiza glabra, Ferula assafoetida, Gymnema sylvestre, Gossypium herbaceum, Phyllanthus niruri, Trachyspermum ammi, Withania somnifera, Andrographis paniculata, Centella asiatica, Curcuma longa, Woodfordia fruticose, Phyllanthus emblica, Terminalia chebula, Tamarindus indica, Terminalia arjuna, Azadirachta indica, and Ficus religiosa). However, many viruses remain without successful immunization and only a few antiviral drugs have been approved for clinical use. Hence, the development of novel antiviral drugs is much significant and natural products are excellent sources for such drug developments. In this review, we summarize the antiviral actions of selected plant extracts and some isolated natural products of the medicinal herbs.
Division-free duplex for wireless applications

Division-free duplex is proposed for future wireless systems, thus providing simultaneous duplex radio transmission on a division-free basis. The required duplex isolation can be achieved by electronic interference cancellation operating at both RF and baseband, with results from an experimental RF system yielding some 72 dB duplex isolation at 1.8 GHz for 200 kHz channelisation.

This cell operates in class AB, allowing an output current greater than the quiescent current. A configuration which allows for the nulling of the third order distortion is derived and the implications of third order nulling on third order intermodulation is explained. Measured results of this cell implemented in 0.4 /spl mu/m silicon-bipolar technology is presented.
Innovations from the Halcrow‐Cardiff University strategic collaboration

Purpose – Innovation process may be characterised by three separate actions: the creation of ideas; their development; and subsequent application for the benefit of industry and society. In water engineering consultancy, the processes that stimulate and manage innovation are not well established. Other organisations are capable of establishing dedicated product or commodity facilities, but the make‐up of the construction industry and its consultancy service organisations, requires a different approach. Conventional models tend to focus on product innovation in a manufacturing environment but it is also necessary to consider innovation from the perspective of the service industries. This paper aims to address this issue.Design/methodology/approach – This paper describes the case of Halcrow, an international civil and environmental engineering consultancy. In 2001, Halcrow Group Ltd and Cardiff University cooperated with each other to research and innovate via a strategic collaboration which involved the sp.
Intelligent control for high performance drives

A new generation of control based on intuition and judgments has emerged. Researchers have given a collective name for this type of control"intelligent control. " The main advantages of this control are its simplicity, adaptability and performance. Complex nonlinear mapping of system's dynamics through terminal characteristics can be obtained without the need for structured models. These controllers can implement design objectives that are difficult to express mathematically in linguistic or descriptive rules. The superior noise rejection capability and the tolerance to the system fluctuations are some of the key advantages over the classical control. They tend to be fast simple and straightforward designs. This paper summarizes two of the most common intelligent controls: fuzzy control and neural network control, with the emphasis on their application to high performance electric drives.
Multi-agent systems applications in manufacturing systems and supply chain management: a review paper

This paper offers a review of the development and use of multi-agent modelling techniques and simulations in the context of manufacturing systems and supply chain management (SCM). The objective of the paper is twofold. First, it presents a comprehensive literature review of current multi-agent systems (MAS) research applications in the field of manufacturing systems and SCM. Second, it aims to identify and evaluate some key issues involved in using MAS methods to model and simulate manufacturing systems. A variety of different MAS applications are reviewed in three different classified research areas: production design and development, production planning and control, and SCM. In presenting a detailed taxonomy of MAS applications, the paper describes MAS application domains from five different perspectives. The review suggests the MAS approach represents a feasible framework for designing and analysing real-time manufacturing operations, since the approach is capable of modelling different levels of agent behaviour and dynamical interactions. The paper also highlights a number of key issues which have to be taken into account in attempting to design MAS-based research paradigms for future applications in manufacturing systems.
Road Surface Identification Approach Based on Vehicle Dynamic Parameters

Road surface adhesion condition identification has major impact on playing the various active safety automotive electronic control devices’ performance as much as possible, the vehicle model with 7 degrees of freedom is established with the application of magic formula tire model and engine model in this paper. By comparing the real-time vehicle dynamic parameters with 6 kinds of typical road characteristics when a vehicle accelerates or brakes, the current road surface type is determined. A road surface identification simulation is carried out when an automobile accelerates on uniform road and brakes on split road by using MATLAB/Simulink software. Finally, a bench test is done to prove the validity of this approach. It is showed by the simulation results that the actual road surface type and the identified road surface type are in good agreement. It can be used for active safety automotive electronic control devices’ road surface identification.

Comparison of different polymeric multimode star couplers for backplane optical interconnect

Optical interconnect is very promising for signal transport in advanced digital systems with high data rates at the board and backplane level. In the ESPRIT-HOL-ICS project we aim at interconnecting a number of boards with an optical backplane, which requires a star coupler topology. Multimode polymeric waveguide boards offer an interesting solution for such interconnect problems because they allow for a more complex functionality than is possible with point to point links. Furthermore, multimode waveguides have the advantage of relaxed coupling conditions. However, the design of multimode waveguide elements (bends, junctions, etc.) is often more difficult than that of single mode structures, due to the uncertainty in modal content.
The Role of K and Ca Channels in Hydrogen Sulfide Induced Relaxation in Arteries Feeding Human Colorectal Cancer

This study was designed to find out the vasorelaxant effects of hydrogen sulfide (H 2 S) on arteries feeding human colon cancer. In addition, it also included the study of the possible roles of potassium (K + ) and calcium (Ca 2 + ) channel types in H 2 S-induced relaxation in the isolated arteries. Sodium sulfide (Na 2 S) showed a potent dose-dependent relaxant effect on Norepinephrine (1X10 - 5 M) precontracted arteries. The use of different specific K + channel blockers (BaCl 2 , 4-AP, GLIB, and TEA) individually indicated H 2 S-induced relaxation was affected by all K channel types participated to a various extent, except Kv channels. Both Kca 2+ and Kir channels played a major role in the induced relaxation, while K ATP played a minor and non-significant role. On the other hand, Kv channel played no direct role, and the induced response curve was very close to that of the control. Possible combinations of K channel blockers showed that some produced synergistic effect to different extent, whereas others produced mild and non-significant effect except at the highest doses used on dose-response curves. Thus, combinations of (GLIB+4-AP), (GLIB+BaCl 2 ) and (BaCl 2 +TEA) caused a highly significant blocking in the induced response curve, while (BaCl 2 +4-AP) and (TEA+4-AP) produced a mild inhibition except at the highest doses used in which the inhibition was significant.
Study of 1.2kV High-k SiC Power MOSFETS Under Harsh Repetitive Switching Conditions

SiC power electronics offers several advantages over Si-based technologies in terms of low-loss switching and power conversion efficiency. Especially 1.2kV SiC power MOSFETs are promising candidates to replace Si IGBTs in various applications. However, the SiC/dielectric interface exhibits peculiarities and challenges that prevent the exploitation of the full potential of these devices. This contribution is dedicated to the Time Dependent Dielectric Breakdown (TDDB) of high-k/SiC interfaces as well as to the threshold voltage (VTH) hysteresis effects under harsh repetitive switching conditions of 1.2kV high-k SiC power MOSFETs, particularly using large negative gate voltage never studied before.
