Three-Dimensional Modelling of Non-Linear Wave-Induced Seabed Response around Offshore Open-Ended Pile

This paper analyses the fluid–seabed–structure interactions (FSSI) around the open-ended pile by applying the in-house solver established on the open-source Computational Fluid Dynamics (CFD) platform. The Reynolds-averaged Navier–Stokes (RANS) equations are solved to simulate the hydrodynamic interactions between waves and open-ended piles. Biot’s poro-elastic theory (quasi-static model) is used to reproduce the wave-induced seabed responses. The parameter analysis indicates that the wave period, degree of saturation of seabed and pile diameter have a great influence on the development of the transient seabed liquefaction depth around the pile. In addition, the distribution of the pore water pressure vs soil depth in the inner zone of the pile presents a “V” shape rotated 90 degrees counterclockwise.

Hybrid genetic algorithm for the economic lot-scheduling problem

The economic lot-scheduling problem (ELSP) is an important production scheduling problem that has been intensively studied over 40 years. Numerous heuristic algorithms have been developed since the problem is NP-hard. Dobson's heuristic has been regarded as the best in its performance. The present paper provides a hybrid genetic algorithm based on the time-varying lot sizes approach in the ELSP literature. Numerical experiments show that the hybrid genetic algorithm outperforms Dobson's heuristic.
Incidence and clinicopathological features of colorectal cancer among multi-ethnic patients in Kuala Lumpur, Malaysia: a hospital-based retrospective analysis over two decades

Background The incidence rate of colorectal cancer (CRC) in Asian countries is increasing. Furthermore, recent studies have shown a concerning rise in the incidence of CRC among younger patients aged less than 50 years. This study aimed to analyze the incidence trends and clinicopathological features in patients with early-onset CRC (EOCRC) and later-onset CRC (at age ≥ 50 years). Methods A retrospective analysis was performed on 946 patients with CRC diagnosed from 1997 to 2017 at Universiti Kebangsaan Malaysia Medical Centre. The time trend was assessed by dividing the two decades into four 5-year periods. The mean age-standardized and age-specific incidence rates were calculated by using the 5-year cumulative population of Kuala Lumpur and World Health Organization standard population. The mean incidence was expressed per 100,000 person-years. Results After a stable (all age groups) CRC incidence rate during the first decade (3.00 per 100,000 and 3.85 per 100,000), it sharply increased to 6.12 per 100,000 in the 2008–2012 period before decreasing to 4.54 per 100,000 in the 2013–2017 period. The CRC incidence trend in later-onset CRC showed a decrease in the 2013–2017 period. Contrariwise, for age groups of 40–44 and 45–49 years, the trends showed an increase in the latter 15 years of the study period (40–44 years: 1.44 to 1.92 to 2.3 per 100,000; 45–49 years: 2.87 to 2.94 to 4.01 per 100,000). Malays’ EOCRC incidence rate increased from 2008–2012 to 2013–2017 for both the age groups 40–44 years (1.46 to 2.89 per 100,000) and 45–49 years (2.73 to 6.51 per 100,000). Nearly one-fifth of EOCRC cases were diagnosed at an advanced stage (Dukes D: 19.9%), and the majority of them had rectal cancer (72.8%). Conclusion The incidence of EOCRC increased over the period 1997–2017; the patients were predominantly Malays, diagnosed at a later stage, and with cancer commonly localized in the rectal region. All the relevant stakeholders need to work on the management and prevention of CRC in Malaysia.
Measurements and prediction model optimisation for signal attenuation in vegetation media at centimetre wave frequencies

The effects of vegetation media on the planning and design of radio links at microwave and millimetre wave frequencies are considerable and must be accounted for by radio system operators and users. The paper presents propagation models for the excess attenuation of signals caused by such media whose mathematical descriptions have been optimised using measured data obtained at three sites. The paper shows that one of the models which expresses the attenuation as a function of frequency and depth of vegetation gives close predictions for the two broad generic cases of trees "in-leaf" and "out-of-leaf" and can be recommended for use in the range 10-40 GHz.
Braess' phenomenon in the management of networks and dissociation of equilibrium concepts

Braess' phenomenon, also known as Braess' paradox, is a phenomenon that has received considerable attention in transportation engineering and planning, as well as in other fields. It has an important implication in the area of investment in transportation networks, namely that adding a new link in a network may increase the cost to the users of that network. In this paper we show this phenomenon in a new environment. Unlike traditional examples, which involve the physical addition of a link to a network (a 0/1 integer decision variable), an example is presented where the decision variable is continuous in nature. Moreover, this example conveys two new messages. First, it is shown that some logical criterion of assigning common resources among users of a network proportional to the number of users competing for common resources may not serve the purpose of efficiency in the sense of minimizing total user travel cost (time). Second, it is demonstrated that the very interdependence of variables and decisions may lead to multi‐equilibrium solutions to the equilibrium flow problem, some of which may not satisfy the once taken for granted characteristic that if the flow pattern satisfies equilibrium conditions, then no user may be better off by unilaterally changing paths.
Detection of Cavitation with Accelerometers Mounted on Piping Outer Surfaces

Cavitation-induced vibration and erosion of pipes is a potentially damaging factor in piping systems. To prevent it, a detection method for cavitation phenomena should be developed. In power plants, especially, it is desirable to detect them from outside pipes during operation. Detection of cavitation phenomena was experimentally investigated in this paper using accelerometers mounted on the outer surface of a pipe upstream and downstream from an orifice. The following results were obtained. (1) With the progression of cavitation, output voltage of the accelerometer varied, and the amplitude and number of the pulse-shaped signals increased. However, it would likely be difficult to distinguish them from noises in an operating plant. (2) It was difficult to recognize the characteristic frequency of cavitation, because the power spectrum density was broad up to the accelerometer limit of 45 kHz. (3) The flow directional distribution of RMS (root mean square) values of accelerometer output voltage varied greatly with the progression of cavitation. Therefore, from comparison of RMS values obtained upstream and downstream from the orifice it seems possible to detect cavitation phenomena in the piping systems of operating plants.
Moving Past the One-Size-Fits-All Education-Training Model of Police Academies to the Self-Prescribed Individualized Exercise Prescription Model

Law enforcement agencies generally employ the “one-size-fits-all” education-training model. Its effectiveness compared to alternative training models has been under scrutiny. Physical fitness scores of Serbian male (n = 98) and female (n = 79) police cadets during their yearly evaluation were compared. Cadets trained for the first 3 years with the “one-size-fits-all” model. In the fourth year, they self-prescribed an individualized exercise program based on the obtained curriculum knowledge. A two-way MANOVA revealed a significant effect of academic years on combined variables (p < 0.001) and significant differences between academic years for deadlift, half squat, standing long jump, sit-ups and 12-min Cooper test time (p < 0.001). Sex also had a significant main effect on combined variables (p < 0.001) with males outscoring females on all of the fitness assessments. For pull-ups, there was a significant year * sex interaction (p = 0.01) with the third year to be pivotal for female and male performance, respectively. In conclusion, the use of a “one-size-fits-all” model, presented differences in physical fitness scores between the years one to three, pointing to its questionable effectiveness. On the contrary, the self-prescribed individualized exercise program of the fourth year elicited greater fitness scores, indicating the need to evaluate the applicability of such a training model more.
Prediction of Observed Response of Base-Isolated Structure

The recorded response of a base-isolated structure excited by the 1994 Northridge earthquake is utilized to validate existing computational methodologies. The isolated structure is located at 1955 1/2 Purdue Avenue in Los Angeles, Calif. , and is a three-story braced-steel-frame residential building supported on helical steel springs and viscoelastic-fluid dampers. The procedure developed during the construction of the building by one of the writers to model the isolation system using generalized-derivative constitutive models is utilized to predict the response of the structure. The predicted response is in good agreement with recorded data at the first and third floors of the base-isolated building. Subsequently, it is shown that the peak values of the response can be satisfactorily predicted using an approximate procedure based on modal analysis. The importance of the isolation system is discussed.

Small business learning through mentoring: evaluating a project

Purpose – The purpose of this paper is to evaluate a small business‐mentoring project, which was delivered in regional Australia. Design/methodology/approach – This paper contains a case study of the mentoring project and focuses on the process and the outcomes of that project from different perspectives. Data collected in semi structured telephone interviews with the Project Manager and the volunteer mentors and a mail and telephone survey of the small business owner/managers who participated in the project, is used to develop a narrative about how the project unfolded and what it achieved. The case study is then examined in light of the literature on small business mentoring. Findings – The case study highlights learning through mentoring can increase self‐confidence while objective outcomes such as increased sales and new jobs are less likely to be outcomes. Research limitations/implications – This paper focuses on one regional area and a single mentoring project while the research was conducted 18 months after the project finished. Evaluation is best conducted during or close to the completion of a project as the lapse in time can lead distort the participants' memory. Practical implications – The case study in this paper highlights some key features of small business mentoring programs: a structured process, mentor training, and the value of other opportunities for interaction between participants during the life of the project. These are all elements future small business mentoring programs can build upon. Originality/value – This paper will be of interest to practitioners involved in the delivery of small business training programs as well as policy makers as it provides an example of a program in operation and the outcomes of such a program.

The G-group heuristic for single machine lot scheduling

Abstract This paper develops a heuristic procedure for generating feasible solutions for the single-machine, multi-product, infinite-horizon, lot scheduling problem. This problem occurs in several practical situations, for example, in metal stamping factories, on appliance assembly lines, in the beverage blending and bottling industries, in paint production and on motor car assembly lines. The proposed heuristic divides the N products into G groups and the products belonging to the same group are produced in the same cyclical pattern. Thus the problem of scheduling N independent products is reduced to that of scheduling G groups of products. Since G is much less than N, the problem is made simpler. The proposed heuristics has two main advantages: implementation facility and effectiveness. Computer codes are available for several mini and micro computers. The effectiveness is demonstrated by two tests. First, we solved the six problems originally solved by Elmaghraby (1978 a). Obviously, the results based .
Income, ethnic diversity and family life in East London during the first wave of the pandemic: An assets approach

Objective: This paper reports first results from a survey of 992 parents and parents to be living in an ethnically diverse and socio-economically unequal borough of East London during the coronavirus pandemic that reduced mobility, closed services and threatened public health. Background: Little is known about the place based impacts of the pandemic on families with young children. We describe the living circumstances of families with children under five or expecting a baby living in Tower Hamlets during the Coronavirus pandemic in 2020, and then examine the relative importance of household characteristics such as ethnicity and household income for adverse impacts on survey respondents, as seen in mental health outcomes. Method: a community survey sample recruited with support from the local council comprised 75% mothers/pregnant women, 25% fathers/partners of pregnant women. Reflecting the borough population, 35 percent were White British or Irish and 36 percent were Bangladeshi, and the remainder were from a wide range of ethnic backgrounds. Adopting an assets based approach, we describe material, familial and community assets using three household income bands and seven ethnic groups. We then use regressions to identify which assets were most important in mitigating adversity. Results: We find that material assets (income, employment, food insecurity, housing quality) were often insecure and in decline but familial assets (home caring practices, couple relationships) were largely sustained. Community assets (informal support, service provision) were less available or means of access had changed. Our analyses find that while descriptively ethnicity structured adverse impacts of the pandemic related changes to family life, income and couple relationships were the most important assets for mitigating adversity as seen in mental health status. Conclusion: Supporting family assets will require close attention to generating local and decent work as well as enhancing access to community assets.
Nutrient Retention in Vegetated and Nonvegetated Bioretention Mesocosms

Thirty well-established 240L bioretention mesocosms were used to investigate retention of dissolved nutrients by bioretention systems. Ten mesocosms were comprised of 80 cm sandy loam, ten of 80 cm loamy sand, and ten of pea gravel with 20 cm of loamy sand. Half were vegetated with shrubs/grasses, while the other half had no vegetation (barren). In the first part of our study, the loam and sand mesocosms were dosed with synthetic storm water comprising 0.8 mg L−1 total phosphorus (TP) and 4.8 mg L−1 total nitrogen (TN). TP retention in the vegetated loam was 91% compared to 73% in the barren, and TN retention was 81% compared to 41% in the barren loam. TP retention was 86–88% in the sand treatments, while TN retention in the vegetated sand was 64%, compared to 30% in the barren. In the second part of our study, all 30 mesocosms were loaded weekly with 45 cm of tertiary effluent with high nutrient loads ( 22.3 m year−1 hydraulic load at a flow-weighted average of 4.5 mg L−1 TP and 4.8 mg L−1 TN, or 1,012 k.
The evaluation of heat stress through monitoring environmental factors and physiological responses in melting and casting industries workers

Aims: Evaluation of heat stress in workers exposed to hot/dry conditions of melting and casting industry is imperative for management of heat stress. This study aims to compare results of heat strain evaluation by monitoring environmental factors and physiological responses. Materials and Methods: This is a cross-sectional study that was conducted on 51 workers of a large melting and casting company in 2010. Wet Bulb Globe Temperature (WBGT) index, heart rate and ear canal temperature were measured by WBGT meter, heart rate monitor and personal heat stress monitor, respectively. Physical activity intensity was assessed based on the ratings of perceived exertion (RPE). Data were analyzed using descriptive statistics and Pearson correlation test. Results: WBGT index in 64.7% of workstations exceeded 30°C and in 41.2% was over 32°C. The value of WBGT index in 69% of work stations exceeded the threshold limit of the ACGIH standard. The physiological strain index (PSI) in 31% of worker was higher than 5, although its mean measured at 3.8 (1.8). Increase in the ear canal temperature in 64.7% of cases (33 persons) was over 1°C. Correlation between WBGT index with ear canal temperature and PSI index, adjusted body mass index and age, was 0.67 and 0.69 (P Conclusion: In hot/dry conditions of melting and casting processes, despite moderate correlation between WBGT index with ear canal temperature and PSI index, work-rest cycles of WBGT index is not applicable for many of the workstations. Therefore, heat stress evaluation based on physiological variables probably has higher validity and is more appropriate.
The Analysis of Fatigueness and Preference for Three Appearance Attributes of LED Light Color

Light emitting diode(LED) technology has been increasingly developed and larger color gamut by LED illuminations can be reproduced; therefore more efficient LED lighting design can be accomplished under a consideration of color emotion. Fifty-two LED colors which are uniformly distributed on the uniform chromaticity space are evaluated in terms of fatigueness and preference and their relation to three color-appearance attributes(lightness, chroma and hue) are investigated. As a result, 23 human observers likely to prefer and feel comfortable, when lightness of a given LED color stimulus increases as well as its chroma decreases. The highest fatigueness score is observed in red color series and the most preferred LED color is found in green color series. In addition, fatigueness and preference show a strong negative linear relation and their Pearson correlation is higher than -0.8.
Simulation of Temperature and Moisture Changes During Storage of Rough Rice in Cylindrical Bins Owing to Weather Variability

Temperature and moisture content are the two most crucial factors limiting the distribution and abundance of arthropods and fungi that contaminate stored grain. A two-dimensional mathematical model, based on the finite-difference method of calculating heat transfer, has been developed to simulate the temperatures in cylindrical storage bins containing rough rice with respect to ambient temperature fluctuations throughout a storage period. The model has been programmed in BASIC, compatible with microcomputers, thus requiring less time for computer simulation of temperatures. Simulated temperatures are incorporated with the equilibrium moisture content (EMC) models of Zuritz-Singh, Henderson, and Chung-Pfost, respectively, to simulate the moisture distribution at different locations of the storage bins. The simulated results have been compared with experimental results and good agreement has been observed both for temperature and moisture content of grain with the exception of the Chung-Pfost EMC model. In most of the cases, EMC predicted by the Chung-Pfost model was lower than the observed EMC values. The heat transfer and EMC models can be used to predict the distribution of temperature and moisture within the bin, for given ambient conditions as a function of time.
Deformation of bowed silicon chips due to adhesion and applied pressure

One potential method to accomplish high-rate nanomanufacturing is to develop processes which allow for rapid transfer of nano-scaled devices from a template to a device wafer. In order to accomplish this transfer, the device wafer must make intimate contact with the template. A similar situation exists in wafer bonding, except that in that case the two wafers remain in bonded contact due to the work of adhesion even after the applied pressure is removed. In high-rate nanomanufacturing intimate contact must be maintained during transfer, while allowing for easy separation afterwards. Wafers typically have waviness and bow which cause a deviation of many micrometers from flatness over the 15-mm length scale of a typical chip. This non-flatness can be a serious problem in the transfer of nanometer-scale elements. In this investigation, a model is developed to examine the effects of applied pressure, bow radius and the work of adhesion on the flattening of a spherically/cylindrically bowed chip. This model uses elastic plate theory and the work of adhesion. An operating window is found which provides intimate contact while allowing for separation once the pressure is removed. It is also shown that the effect of adhesion is to produce a discontinuity in the internal bending moment, at the separation boundary, which is proportional to the square-root of the product of the work of adhesion and the flexural rigidity. This "moment-discontinuity" method can be applied to other problems involving adhesion of elastic plates.
