Design of time-to-lane-crossing based haptic steering guidance

Current haptic control systems provide feedback torques based on a lateral deviation with respect to a reference trajectory (i.e., centre of the lane), which do not capture the satisficing behaviour human beings typically adopt during a lane keeping task. As such, a novel time-to-lane-crossing-based controller is proposed, which is expected to provide more human-like guidance. The aim of this study is to describe a novel time-to-lane-crossing-based controller and investigate its potential as an alternative to previous reference-trajectory-based guidance. In a simulator study twenty-four participants drove three trials through a single-lane, 10.8 km long road (width: 3 m), receiving three types of guidance, namely 1) none (manual), 2) reference based controller, 3) TLC-based controller. Results showed that both the reference-based, as well as the TLC-based guidance provided significant safety benefits, in terms of more centred and less varying lane position, and higher safety margins. Moreover, no significant differences were revealed between the two guidance approaches. In conclusion, the TLC-based guidance is a potential alternative to reference trajectory-based guidance. Nevertheless, a more detailed analysis is warranted to investigate the two approaches in different driving conditions, like road width, straights, and curves.
FAULT CURRENT LIMITING CIRCUIT BREAKER IN DISTRIBUTION SYSTEMS

The Powerful CB project is a collaboration between UK Power Networks (UKPN) and ABB to develop and demonstrate an 11 kV Fault Current Limiting Circuit Breaker, FLCB, in an existing UK Power Networks substation. The technology utilized in the FLCB is a combination of power semiconductors and mechanical switches, enabling fast limitation, low losses and compact installation. In operation it limits a prospective fault current of 25 kA rms to maximum 13 kA peak in less than 1 ms after the trip signal.
Poly (Methacrylic Acid)-Grafted-Okra Gum: Synthesis, Characterization and Evaluation as Mucoadhesive

Recently, worldwide extensive attention is being paid in exploration and exploitation of pharmaceutical excipients from natural resource. Various natural polysaccharides have been significantly reported as prospective drug delivery carriers. These natural gums are preferred over synthetic polymers because of their biocompatibility, low cost, free availability and biodegradability. But due to variable chemical composition, microbial load, microbial growth and hange in viscosity upon aging, acceptability is low compared to commercial synthetic products. Tailoring or modification may be an approach to make them smart as drug carriers specially in order to modulate the site of drug release and it’s kinetic. The chemical modification of okra gum (OG) was the main objective of the present study in order to make it potential mucoadhesive for the application in mucoadhesive drug delivery. In this study, methacrylic acid was grafted onto okra gum. At first, okra gum has been isolated from the fruits of Hibiscus esculentus. Poly (methacrylic acid)-grafted-okra gum (PMAc-g-OG) was synthesized employing a microwave- promoted and redox-initiated method. Potassium persulphate was used as free- radical-initiator. Methacrylic acid was mixed to 1% solution of OG and then 30 ml of potassium per sulphate aqueous solution was added to the previous mixture along with continuous stirring. The mixture was exposed to microwave in a domestic micro-oven. The mixture was kept overnight and the copolymer was collected and purified using acetone and aqueous methanol (30% v/v) subsequently. The copolymer was characterized by elemental analysis, FTIR, DSC-TGA, and 13C NMR study. Ex-vivo mucoadhesion test was performed using goat stomach. A highest % grafting of 448.32% was found in the synthetic procedure employed in the study. The characterization studies also substantiate the successful grafting. Ex-vivo mucoadhesion study also showed excellent mucoadhesive capacity over a period of 16 hours. The study exhibited that the method employed was very simple, less time consuming, one-pot and without N2 atmosphere. The copolymer also exhibited excellent mucoadhesivity which might be applied in different mucoadhesive drug delivery systems such as prolonged release gastroretentives, buccal gels, etc.
Immunocompromised Districts of Skin: A Case Series and a Literature Review

BACKGROUND: The concept of immunocompromised districts of skin has been developed by Ruocco and helps to explain certain aspects of the macromorphology of skin diseases. This concept unites the isomorphic response of Koebner and the isotopic response of Wolf. CASE REPORTS: We present different cutaneous conditions which can lead to immunocompromised districts of skin such as scars, radiodermatitis, lymphedema, disturbed innervation or mechanical friction etc. Typical and rarer skin disorders associated with them are discussed and illustrated by their observations. CONCLUSION: At this moment, we wish to inform dermatologists and non-dermatologists about Ruocco’s concept and its implications.
O C ] 1 7 O ct 2 01 9 Parameter Estimation of Nonlinearly Parameterized Regressions without Overparameterization nor Persistent Excitation : Application to System Identification and Adaptive Control

In this paper we propose a solution to the problem of parameter estimation of nonlinearly parameterized regressions—continuous or discrete time—and apply it for system identification and adaptive control. We restrict our attention to parameterizations that can be factorized as the product of two functions, a measurable one and a nonlinear function of the parameters to be estimated. Although in this case it is possible to define an extended vector of unknown parameters to get a linear regression, it is well-known that overparameterization suffers from some severe shortcomings. Another feature of the proposed estimator is that parameter convergence is ensured without a persistency of excitation assumption. It is assumed that, after a coordinate change, some of the elements of the transformed function satisfy a monotonicity condition. The proposed estimators are applied to design identifiers and adaptive controllers for nonlinearly parameterized systems. In continuous-time we consider a general class of nonlinear systems and those described by Euler-Lagrange models, while in discrete-time we apply the method to the challenging problems of direct and indirect adaptive pole-placement. The effectiveness of our approach is illustrated with several classical examples, which are traditionally tackled using overparameterization and assuming persistency of excitation.
LINKING SERVICE QUALITY , CLIENT SATISFACTION AND LOYALTY TOWARDS AUDIT FIRMS IN MALAYSIA

The aim of this paper to propose a conceptual model that illustrates how service quality leads to client satisfaction, which in turn leads to client loyalty. According to the service quality model, it is argued that the customer exists in two parts, namely as perceptions and expectations. The five dimensions of service quality, i.e. reliability, responsiveness, assurance, tangible and empathy were used to explain in theoretically between the roles of these variables in the relationship. Client satisfaction effects service quality and client loyalty relationship. The conceptual significant and how it touches the relationship are discussed. The limitation of the study is this paper only focused on the five dimensions of service quality while ignoring other aspects that also have a significant contribution to client loyalty. The proposed model can be used by audit firms or other managements to perform better about their service quality due to its ability to influence customer satisfaction that lead to customer loyalty.
Robust Synchronization for IM / DD OFDM Optical Communication Systems

Optical orthogonal frequency division multiplexing (OFDM) is at the forefront of next generation optical communication research in both fiber and optical wireless communication systems (OWC) [1]. A viable method to using the optical channel, especially for OWC, is through intensity modulation and direct detection (IM/DD) of optical sources, such as laser diodes and light-emitting-diodes (LEDs). In conjunction with OFDM, IM/DD systems can provide high spectral efficiency, adaptive modulation, and low-complexity equalization. In optical OFDM, there is no carrier frequency offset or phase data and the signal is real and unipolar. Nevertheless, a robust synchronization method is needed that maintains effectiveness under time/frequency offsets, noise and interference. There are typically two types of synchronization that uses a preamble: one that cross-correlates with a known local copy of the preamble and another that cross-correlates separate parts of the transmitted preamble, which structure is repetitive in nature. This paper focuses on using a known local copy based synchronization and optimizing it to provide the best accuracy and least latency. A recent state-of-art method that employs cross-correlation with known local copy is introduced in [2]. This method reconstructs an asymmetrically-clipped optical OFDM (ACO-OFDM) signal into an bipolar OFDM signal and cross-correlates with a known local copy of the bipolar OFDM signal. In this paper, we propose a linear frequency modulated (LFM) chirp preamble for synchronization and evaluate and compare its performance in simulation and experimentally with the ACO-OFDM based synchronization method. We evaluate both synchronization methods under a visible light communications (VLC) or LiFi environment where dimmable lighting is an important parameter to the practicality of the system [3]. Reverse polarity optical OFDM (RPO-OFDM) transforms a typical optical OFDM signal, in this case an ACO-OFDM signal, into a pulse-widthmodulation (PWM) shape that allows for dimming and data transmission [4]. Therefore, the synchronization preambles are evaluated attached to a RPO-OFDM modulation scheme.

Building Institutional Trust Through Service Experiences—Private Versus Public Provision Matter

Welfare service experiences are known to shape citizens' trust in public institutions and their support of the welfare state. But, there is poor understanding of how this relationship is shaped in systems of mixed provision, that is, welfare states that use public in-house as well as contracted private providers for publically funded services. Drawing on the notion of system trust this article provides a theoretical account of how mixed-provision welfare systems condition the relationship between service experience and trust, affecting the legitimacy of the state. Utilizing a randomized vignette experiment with participants in a general citizen survey in Sweden, we investigate whether it matters for the formation of institutional trust if the welfare service is provided by a public or third-party private provider. The main result show that the spillover of trust from positive service experiences with the provider to trust in public institutions is higher in cases of public service provision. Thus, the possibility of using welfare services to build trust in the welfare system seems to be greater when public provision is used.
A novel approach for approximation based spatial data classification

The Geospatial data analysis has been popular recent years due to its wide and vast applications. These applications focus on an efficient classifier towards accuracy. In general, the accuracy depends on the features that represent the objects. The conventional classifiers have an ability to construct the optimal features in objects, however fail to handle the large datasets. The recent research towards spatial data classification has been focusing on machine learning and deep learning approaches. The machine learning based methods are popular because of their robust performance in classifying the spatial data. In this paper, we investigate a novel approach to construct the optimal features and the significant accuracy of the classifier. At first, the rough set based approach is investigated and then the βapproximation based method is used to get the significant accuracy in classification. The cross validation and miss classification rate are used to assess the proposed model.
Monotone Comparative Statics under Monopolistic Competition ∗

We let heterogeneous firms face decisions on an arbitrary number of complementary activities in a monopolistically-competitive industry. One key insight is that firm-level complementarities may assert themselves much more clearly at the industry level than at the firm level of analysis. The response of an individual firm to exogenous changes in the parameters of its profit maximisation problem is ambiguous due to indirect effects through changes in industry competition. Only in special cases are firm-level comparative statics monotone. Turning to the industry level, we provide sufficient conditions for first-order stochastic dominance shifts in the equilibrium distributions of the activities regardless of the ambiguities prevailing at the firm level. As all these results apply to many recent and well-known models of international trade, they are more than just a theoretical curiosity.
Empirical Comparison of Anonymization Methods Regarding Their Risk-Utility Trade-Off

We present here a methodology to compare statistical disclosure control methods for microdata in terms of how they perform regarding the risk-utility trade-off. Previous comparative studies (e.g. [3]) usually start by selecting some parameter values for a set of SDC methods and evaluate the disclosure risk and the information loss yielded by the methods for those parameterizations. In contrast, here we start by setting a certain risk level (resp. utility preservation level) and then we find which parameter values are needed to attain that risk (resp. utility) under different SDC methods; finally, once we have achieved an equivalent risk (resp. utility) level across methods, we evaluate the utility (resp. the risk) provided by each method, in order to rank methods according to their utility preservation (resp. disclosure protection), given a certain level of risk (resp. utility) and a certain original data set. The novelty of this comparison is not limited to the above-described methodology: we also justify and use general utility and risk measures that differ from those used in previous comparisons. Furthermore, we present experimental results of our methodology when used to compare the utility preservation of several methods given an equivalent level of risk for all of
Impact of land use activities on Subin and Aboabo Rivers in Kumasi Metropolis

Water resources have come under a lot of threat in recent years from human activities especially in the urban environment as their protection seem to be neglected not only by the populace but also the responsible institutions as well. Within this context, study seeks to address the issues of compatibility of land uses with water bodies. Sample size of 90 activity units selected at 90% confidence level and a margin of error 0.1 was used for data collection. It was found that common threats emanate from land use activities carried out along the buffer zones of these vital resources. The study identifies the various factors such as land, land users and their desires that influence land use activities along water bodies and makes recommendations such as the adoption of buffer zone policy towards land use management along water bodies in an urban area in the case of Subin and Aboabo Rivers in the Kumasi Metropolitan Area. The study reveals that there has been a massive encroachment of the buffer zones of the Subin and the Aboabo Rivers leaving patches of vegetative cover thereby exposing the river bodies to direct sunshine. In addition, activities located along these rivers are as a result of proximity to market, cheaper lands, availability of water, and closer to work place. According to the 1963 Town Planning Scheme, all land close to the main streams should be green belt zone. These natural flood plains of streams, no buildings were supposed to be erected on them. With increase in population and urbanisation however, these green belts have been encroached upon. Therefore, creating community awareness of the need to protect water bodies, enforcement of water protection related laws and institutional strengthening are imperative. Key words: Rivers bodies, land use change, water resource management.
Assessment of Levels of Some Metals in Water and Fish from Jos, Plateau State, Nigeria

Aim: This study was designed to assess the levels of chromium (Cr), manganese (Mn), cobalt (Co) and nickel (Ni) in water and fish to monitor the toxicity risk of consuming these fish. Place and Duration of Studies: The water and fish samples were obtained from Farin gada river, Liberty Dam, Dahwol-Tohort and Diye-Tohort mining ponds, all within Jos Metropolis, Plateau State, Nigeria, between March and April, 2018. Methodology: Water and six fish species samples were collected from four different locations, digested and analysed using Buck Scientific Atomic Absorption Spectrophotometer, model 210VGP. Results: Farin gada river had all the four metals studied in varying concentrations in the following order Mn>Ni>Co>Cr with Mn having the highest mean concentration of 0.4133±0.0100 mg/L. The concentrations of the metals in the other three sources were in the order of Ni>Co>Cr with Mn not detected. Cr also was not detected in Lamingo Dam. The concentrations of Mn and Ni in all the water sources were higher than the World Health Organisation (WHO) maximum permissible limits of 0.05 mg/L and 0.06 mg/L respectively. Petrocephalus bovei recorded the highest mean concentrations of Mn and Ni, while Co was highest in Clarias gariepinus species. The concentrations of these metals in the head, body and gills of the fish species showed that the head of Petrocephalus bovei species had the highest concentrations of all the metals except chromium. Fish species from other water sources exhibited the same general pattern of Head˃gill˃body except Co which was found to accumulate more in the body than in other parts of the fish. Conclusion: The results showed that there was biomagnification of these metals from water to the fish as the concentration of the metals in the fish far exceeded those of the water sources from which they were obtained and Petrocephalus bovei species has the highest potential to biomagnified all the metals.
Effect of phosphorus content on the wettability of NiP coated surfaces by SAC 305 alloy

The aim of this study was to determine the effect of the chemical composition of Ni-P coating on the wettability kinetics of SAC305 liquid solder in contact with the Ni-P coating. The study was conducted in vacuum, at 230°C, for 5 minutes, using the sessile drop method in combination with a separate heating of the two test materials, allowing for experimental determination of the contact angle θ. The study used a SAC305 solder (Sn base, Ag 3 wt. %, Cu 0.5 wt. %) and a nickel substrate (Ni 99.8 wt. %) onto which Ni-xP coating of two different levels of phosphorous was applied (x = 4.3 wt. %, or 11.6 wt. %). After the tests of wettability were performed, structural analysis of the surface of the samples was performed by scanning electron microscopy, focusing on the observation of the border SAC305/substrate. In order to determine the effect of phosphorus in the Ni-P coating on the strength of the SAC305/Ni-xP/Ni joints formed, cross sections of samples were tested for shear strength using the improved method of the push-off shear test. It was found that, for the selected range of 4.3 ≤ P ≤ 11.6, increase in the phosphorus content in the coating improves the wettability of the liquid systems tested with the SAC305 solder, but it is an apparent effect resulting from the solder’s penetration of the structural discontinuities formed in the layer of Ni-11.6P, due to phase transitions. For the SAC305/ Ni-11.6P/Ni sample, value of the contact angle θ = 54° is
Genetic linkage mapping of Arabidopsis lipid related genes in Brassica napus

To unravel the genetic basis of seed oil content in B. napus, here, we present a high-density molecular linkage map based on Brassica EST and BACs derived markers, which were sequence homology to corresponding Arabidopsis genes, especially for those involved in plant lipid biosynthesis or recycling pathways. A total of 374 newly developed markers were integrated into the framework of previously published SG map and formed a new map version of 477 markers with a combined map length of 1956.7 cM. Most of the newly added markers (74.9%; 280/374) are functional markers, and approximately half of them (137) exhibited high homology to 112 acyl lipid metabolism related genes in Arabidopsis. Comparative genomic analysis between B. napus and A. thaliana revealed 32 large syntenic regions. In parallel, a detailed QTL analysis for seed oil content was performed using the new map version across 11 environments and identified nine significant QTL. Co-location analysis revealed that a total of 28 acyl lipid metabolism related candidate gene loci were linked to seven of the nine QTL, indicating their potential role in genetic variability control on seed oil content.
Prefetching Strategies to Improve Web Performance

Web prefetching is fetching web pages in advance by proxy server/client before a request is send by a client/proxy server. The major advantage of using web prefetching is reduced latency. When a client makes a request for web object, rather than sending request to the web server, it may be fetched from a pre-fetch area. The main factor for selecting a web prefetching algorithm is that its ability to predict the web object to be pre-fetched in order to reduce latency. Web prefetching exploits the spatial locality of web pages, i.e. pages that are linked with current page will be accessed with higher probability than other pages. Web prefetching can be applied in a web environment as between clients and web server, between proxy servers and web server and between clients and proxy server.
Cross-linguistic robustness of infant word segmentation algorithms : over-segmenting morphologically complex languages

Infant word segmentation algorithms are plausible only if they are cross-linguistically valid. They are conventionally evaluated on the word level, tending to yield lower segmentation scores for morphologically complex languages. However, they might segment morphologically complex languages in smaller chunks e.g. morphemes. Such errors could be useful for later linguistic analysis. In this work in progress, a set of algorithms segment corpora from nine typologically diverse languages and oversegmentation errors are counted. The results of this study could inform on the segmentability of morphologically complex languages and the generalizability of segmentation strategies.
