Authors: Engemise Samuel , Thompson Fiona , Davies William
Published: January 2014

Prolonged oligohydramnios following extreme preterm prelabour rupture of membranes (EPPROM) is traditionally associated with a high morbidity and mortality to both the mother and the baby. The clinical maternal evaluation and fetal ultrasound assessment may provide important prognostic information for the clinicians and should be taken into account when counselling the patients so as to provide them with enough information to make decision of continuing or interrupting the pregnancy. Current financial constraints on the National Healthcare Service (NHS) resources make it imperative for clinical decision-makers and budgetary planners to make the right decision of continuing or terminating a second trimester pre-viability amniorrhexis for desperate parents. To assess the economic consequences following EPPROM, the risk of infection to both baby and mother, psychological impact on the parents and associated complications and further disability after delivery on this fragile group of patients to the NHS resources. We review the clinical course, outcome, and the challenges to parents and health care professionals on three pregnancies complicated by EPPROM, occurring before 24 weeks’ gestation with a membrane rupture to delivery interval (latent period) of 14 days or more. The anticipated birth of an extremely premature infant poses many challenges for parents and health care professionals. As parents are faced with difficult decisions that can have a long-term impact on the infant, family and country’s resources, it is critical to provide the type of information and support that is needed by them. Taking all these into consideration with the period of ventilation and respiratory assistance in Neonatal Intensive Care Unit (NICU) is essential to provide maximum chances for survival, minimizing the risk for long term sequelae of the neonate and provides the parents enough time to decide on making the right decision with the associated guidance of the healthcare provider.

Authors: Lee Donggeon , Kim Dong-Chan , Kwon Daesung , Kim Howon
Published: January 2014

Recently, due to the advent of resource-constrained trends, such as smartphones and smart devices, the computing environment is changing. Because our daily life is deeply intertwined with ubiquitous networks, the importance of security is growing. A lightweight encryption algorithm is essential for secure communication between these kinds of resource-constrained devices, and many researchers have been investigating this field. Recently, a lightweight block cipher called LEA was proposed. LEA was originally targeted for efficient implementation on microprocessors, as it is fast when implemented in software and furthermore, it has a small memory footprint. To reflect on recent technology, all required calculations utilize 32-bit wide operations. In addition, the algorithm is comprised of not complex S-Box-like structures but simple Addition, Rotation, and XOR operations. To the best of our knowledge, this paper is the first report on a comprehensive hardware implementation of LEA. We present various hardware structures and their implementation results according to key sizes. Even though LEA was originally targeted at software efficiency, it also shows high efficiency when implemented as hardware.

Authors: Nejad Fereidoon Moghadas , Azarhoosh Ali Reza , Hamedi Gholam Hossein
Published: January 2014

Fatigue cracking is the main form of structural damage in flexible pavements. Under the action of repeated vehicular loading, deterioration of the asphalt concrete materials in pavements caused by the accumulation and growth of the micro and macro cracks gradually takes place. The results of a laboratory study evaluating the fatigue properties of hot-mix asphalt (HMA) mixtures using indirect tensile fatigue test (ITFT) were investigated in this paper. The HMA mixtures containing 0%, 35%, 70%, and 100% of recycling concrete aggregate (RCA) were plant prepared with one source of aggregate, limestone, and one type of binder, 60/70-penetration grade. In this paper, it is shown that the use of recycled concrete produced by crushing demolished concrete elements can increase the efficiency of asphalt mixes, reduce primary production costs and prevent much fullness of the recycled materials in the environment. It was found that replacing up to 100% of the virgin aggregate by RCA improved the fatigue properties of the asphalt mixtures.

Published: January 2014

Standing is one of the most preferred working postures in the manufacturing field as it provides a large degree of physical freedom and mobility to the human operators. In addition, the cognitive perceptions of the increase in work effectiveness and productivity rate among the human operators are the reasons this working posture is practiced. However, to stand erect for a long period of time or otherwise known as Prolonged Standing often leads to physiological discomfort, fatigue and even health issues such as Musculoskeletal Disorders (MSDs). The aim of this paper is to review on the effects resulting from Prolonged Standing and disseminates the information on the ergonomic interventions to relieve standing fatigue. Selected journals and research papers related to Prolonged Standing were reviewed and the findings showed that varying the floor conditions such as installing anti-fatigue mat and using shoes with soles would help in relieving discomfort associated with the cumulative effects of Prolonged Standing. Nevertheless, further research is needed to truly quantify the effectiveness of these suggested ergonomics interventions in real world implementations such as in the manufacturing industry.

Health problems such as musculoskeletal disorders and repetitive syndrome injuries are commonly reported by office workers worldwide. The aim of this study is to evaluate the level of awareness and understanding of ergonomics among a local institute of higher learning office workers who use computers every day in their work. Secondly is to identify suitable ergonomics intervention programs for the workers. Survey questionnaires were developed as online survey and the link was emailed to all staff. However, questionnaire in hardcopies were also prepared and manually distributed to all the different departments in UPNM such as the Registrar, Bursary, HEPA, Library, Publisher, as well as Centres and Faculties. The number respondents were 50 out of 120 staffs and 62% of the respondents were female. Questionnaires were divided into sections to get information on the demographic background, to evaluate the level of awareness regarding ergonomics, to determine ergonomics trainings or exposures experienced, to investigate any problems related to health problems or discomfort and workstations as well as physiological and psychological complaints. The hyphothesis that the Universitys workers have very little knowledge regarding office ergonomics and yet some of them have already experience work-related musculoskeletal disorders was found to be true. The result shows that the current level of ergonomics awareness in UPNM could be considered as at the beginner level. Fifty six presents of the respondents in the first instance relate ergonomics to health, back pain and work-related injuries separately. More than 50% reported moderate pain and soreness at various parts of their body. Therefore, the next step of ergonomics intervention that could be introduced is to educate them through educational tools and expert talks.

Published: January 2014

This paper presents a study in batik industry with the objective of determining any musculoskeletal disorders (MSDs) among canting batik workers in Kuala Terengganu. The MSDs symptoms were identified through questionnaires modified from a Standardized Nordic Questionnaire (SNQ) and from observational techniques by using a postural analysis tool, Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment (REBA). The results of questionnaires revealed that MSDs occurred at a high rate which the highest rates of MSDs prevalence were reported in shoulders (64.5%). By assessing postural using the REBA software, the score 4 placed it in medium risk level. However, there are other factors contribute to the existence of MSD such as prolong standing, repetitive movement and poor workstation design. These parameters are not taken into account in the RULA and REBA analysis. Thus, designing an ergonomic workstation may prevent awkward postures to provide a maximum comfort to the batik workers and consequently enhance the productivity.

Published: January 2014

The ability for motorcycle to be detected is an important aspect in preventing crash involving motorcycle which is the most dominant vehicle in emerging countries. Widely referred as conspicuity, the crash factor is appropriately addressed by the introduction of mandatory daytime running light (DRL) law and is usually a success story in many parts of the world. In 2011, there was a motion introduced in the 64thsession of the United Nations Working Party on Lighting and Light-Signalling (GRE) for amber position lamp (APL) to be made mandatory on motorcycle as additional measure to improve motorcycle conspicuity. An experiment was designed to evaluate conspicuity level of motorcycle headlamp and tail lamp equipped with APL over motorcycle with present DRL setting (baseline). 15 participants simultaneously rated both motorcycles which are placed in parallel, at different distances and times of day. Motorcycle with APL was noticeably better detected from rear than front at 50 meter and 100 meter distance, as well as during night time and twilight. Median conspicuity level between night time and daytime and between night time and twilight was also distinctly different for rear lamp. These findings suggest that APL introduction could enhance motorcycle conspicuity especially for rear lamp position.

Authors: Xia Kun , Li Jun Tao , Kise Hiroshi
Published: January 2014

Unidirectional circulation-type material handling system on a single loop with a shortcut is a typical and basic unit in a flexible manufacturing system (FMS). It is widely used in the FMSs. Superposition efficiency of the basic unit often determines the one of the whole system. In this system, a fleet of AGVs circulates along a loop with short-cut unidirectionally. After AGVs load jobs, jobs are sent to process at a processing station set along the path, and then unload at an unloading station. AGVs continue to circulate until all jobs are processed. The AGVs can't be overtaken except in the cross point. So it is difficult to avoid the interference between AGVs. Different scheduling rules have an important effect on the unidirectional circulation-type material handling system on a single loop with a shortcut. To decrease the interference and improve performance of the system, this paper makes a mathematical model of this system and put forward optimal scheduling rules. Experiment results show that the optimal rules can decrease the interference time and improve efficiency, so as to achieve the optimal performance.

Published: January 2014

The object of this study is to utilize FE-SPH method to simulate the dynamic behavior of bioprosthetic heart valve during systole. Two kind of bioprosthetic heart valve numerical models are designed based on membrane theory, and they are represented by FE mesh, the blood is modelled as SPH particles. The interaction between the blood and bioprosthetic heart valve is carried out with contact algorithms. Results show that: when the valve leaflets are opening, compared with that of spherical valve, the stress and strain states of cylindrical valve are unstable, and the peak Von Mises is also higher, which high peak stress and its instability may induce the fatigue of valve. The valve opening time of columnar valve leaflets is longer than that of spherical ones, which reduces the blood ejection time. Above results indicate that spherical valve is superior to cylindrical valve. The FE-SPH method is capable of simulating the fluid structure interaction between the bioprosthetic heart valve and blood during the systole.

Authors: Pi Da Wei , Dong Wei , Wang Xian Hui
Published: January 2014

In this paper, the problem of vehicle yaw control using differential braking is investigated. The proposed control structure employs the wheel slip controller to apply differential braking to generate the yaw moment calculated by the yaw controller. A fuzzy logic based target slip allocation method is also designed. Due to system uncertainties and wide range operation conditions, two different yaw controller which are based on sliding-mode control and PID control are designed, and their performances are compared by hardware in loop simulation. The obtained results show the effectiveness of the proposed control structure with both yaw controllers, but the sliding mode based yaw controller can be more robust.

Authors: Liang Wen Jiao , Li Jun Qiu
Published: January 2014

This paper describes a control strategy of drive modes switch for an independent eight in-wheel motor drive vehicle. There are three drive modes, and they are eight-wheel drive with ASR mode, eight-wheel drive mode and four-wheel drive mode. The control strategy is designed to improve the integrated performance of the vehicle, such as safety, dynamic performance and economic performance, but the previous research can only improve one of them. When the road adhesion coefficient is very small, the vehicle will drive in eight-wheel drive with ASR mode to ensure the vehicles safety, when the driver torque demand is very big, the vehicle will drive in eight-wheel mode to get better dynamic performance and when the driver torque demand is very small, the vehicle drive in four-wheel mode to get better economic performance. The vehicle switches among the three modes according to the driving condition. Simulations of the new control strategy were carried out on two different driving conditions. The results showed that an improvement in safety or economic performance was achieved with the control strategy.

Published: January 2014

A Switched Reluctance Motor and Generator (SRMG) has a simple double salient pole structure that uses reluctance torque and does not use a permanent magnet, making the unit price low. This kind of structure makes it mechanically tough, have outstanding output characteristics making it used as traction purpose. However the noise, vibration and torque ripple is bigger than other motors and because it does not have any magnetic flux in the rotor, it is not useful in regenerating.[[
In this paper, novel regenerating method with separate excitation driving technique is presented. It is different from the existing regenerating brake that uses the remnant flux on a separate excitation type by using a parallel switching base to redirect portion of the flux path to excitation and the rest to generation. The proposed method makes it able to use a larger portion in generating, there is no limitation in the excitation current in order to generate and the control of the output is simple. Because the proposed method is based on the parallel switching technique the number of switch per phase does increase.
However in motor mode the division of current goes down making it easier to go in generating mode. The proposed method is generated upper 50% regenerating power rate more than general method. In order to prove the possibility, a simulation of flux flow using FEM is applied. The proposed method is also verified by experiment result.
Driving Intention Based Optimal Shift Control for Automatic Transmission
Authors: Zhu Sheng , Hu Jun Hua
Published: January 2014

In general, discomfort and slipping loss cannot be avoided during gearshift due to discrete gear ratio. Therefore, improving shift quality has long been concerned in the developing process of automatic transmission. This paper presents the equivalent dynamic model of automatic transmission, based on which optimal theory is then applied to obtain ideal engaging/disengaging torque control. Driving intention is also taken into consideration in the optimal control by deciding the weighted values for slipping loss and jerk items in the target function with fuzzy logic method. The simulation results show a good reflection of driving intention and could be used to decide band/clutch apply pressure in the control unit developing process afterwards.

Published: January 2014

A micro-fluid turbine with mechanical energy storage system is designed and successfully tested in laboratory. As energy supplement for deep ocean installations, this patent design solved the problem of difficult generating electricity in ultra-low speed flow. The conventional marine current turbine can hardly get start in flows with velocity lower than 0.5m/s, whereas the marine current speed is seldom higher than one knot in deep sea. By adding a mechanical energy storage system, the rotor of the micro-fluid turbine first captures the fluid kinetic energy from the ultra-low speed flow, and then the energy transferred to the mechanical energy storage system, in which a plane scroll spring is used to store the limited energy and drive the generator automatically when it has enough potential energy. Simulation and laboratory test show that this method has potential for power generating in low density ocean current environment.

Published: January 2014

The growing demand for accurate performance simulations of high-power Li-ion traction batteries requires a fast and effective method. In this paper, an advanced estimation model is proposed to evaluate Li-ion traction battery performance in pure electric vehicle (PEV) applications. The estimation model, which combines road load simulation and lumped parameter analysis, can predict vehicle traction power requirements and entire battery performance parameters both for charge (regenerative braking or grid charging) and discharge (traction power) processes. The model is validated for a battery pack in a PEV operating over three representative driving cycles: (i) the new European driving cycle (NEDC), (ii) 60km/h constant speed driving cycle, and (iii) 30min maximum speed driving cycle. The results show that the combined performance model output corresponds well with measured data. Thus, this new proposed model can be used to validate battery pack performance during in-vehicle use with reasonable accuracy.

In this paper, a method is put forward to forecast the MOVs state based on the improve recursive neural network. The result indicates that recursive network is more adapted to the state forecast of MOV. Because the running state of MOV is closely related to the system voltage and the environment, the state forecast method affected by multi-factors should be further considered.
Seven Factors in Evaluating Recommender System
Authors: Kang Li Ting , Wang Yong
Published: January 2014

Recommender system (RS) has been evaluated in many but incomparable ways beyond accuracy and thus proposing an evaluation framework to synthesize the existing strategies seems a solution. However, few scholars did it so far. Through literature review, user interview and expert assessment, this study proposed a theoretical evaluation model of RS and then formed the assessment tool, RS Evaluation Questionnaire (RSE). The results showed that RSE was an effective tool to evaluate a recommender system, with its reliability (Cronbachs α=0.803) and validity meeting the requirements of psychometrics. Seven factors such as Perceived Quality and Perceived Ease of Use were generated by factor analysis, accounting for 63.126% of the variance. Furthermore, regression analysis indicated that different combinations of RSE factors could significantly predict User Satisfaction, Reuse Intention and positive Word-Of-Mouth (WOM) spreading willingness. Enlightenments for future research and practice were discussed as well in the end.
