Decision Support and Statistical Quality Control

Examines some principles of the design and implementation of decision support systems in the context of statistical quality control. These principles are a function both of the level within the organization at which the decision is made and of the type of decision that is made. The principles are well known in the field of decision support systems and have proved effective. Argues that these principles are of great value to researchers, managers and quality specialists in the field of statistical quality control as well. The argument is supported by a number of actual examples in the application of statistical quality control where knowledge of the principles proved of value in improving quality.
Exploring the industrial placement experience for mechanical engineering undergraduates

Abstract This paper explores the attitudes of undergraduate engineers towards work placements in industry. This research also assesses the placement experience in terms of student learning outcomes and future employment aspirations. Quantitative and qualitative data were collected from three groups: (i) those recently returning from a placement; (ii) those yet to go on placement and (iii) those who elected not to go on placement. Semi-structured interviews gathered experiences and perceptions from all three groups and formed the basis of attitude questionnaires distributed to 276 undergraduates at the University of Bath. Students were asked what value they attached to a year in industry, what improvement in personal transferable skills (such as team-working, time-management, communication and learning) they felt was gained and their perception of the placement experience in terms of aspirations of future employment. Factors influencing the decision of whether or not to undertake a placement were explored. The marks of the students in each of the three populations were scrutinised in order to determine any academic differences between the groups and to assess any value added by a placement in terms of improved performance on returning to university. Finally, this paper identifies reasons why undergraduates do not elect to undertake placements, asking if these important decisions are well-informed or otherwise.
Green building design in Egypt from cost and energy perspectives

Sustainable concepts in building designs have potential to enhance building performance and to reduce operating cost. With investors in developing economies overlooking all considerations except profit, this paper aims at promoting green construction in Egypt by presenting possible savings that investors could earn. The paper introduces an integrated framework to allow building design stemming from basic sustainable approaches. The framework can function as an optimization/simulation platform to automatically improve building designs. Following the framework principles, a model was developed that functions through four modules: a System Builder to create various envelope systems alternatives; a Building Integrator to form a complete design; a Design Evaluator to assess costs and energy; and Design Adaptation that allows optimization and simulation. The model represents a comprehensive yet easy application tool for cost and energy trade-off analyses that suits early design stage. A comparative analysis showed that green designs exhibited lifecycle and annual energy savings reaching 16.3% and 50%, respectively. A sensitivity analysis was performed to show the relationship between changes in electricity prices and percentage saving in lifecycle cost, optimum design and payback period. Furthermore, simulation of possible building designs is conducted to offer trade-off comparison between initial and energy costs of different designs.
"Molecular Docking Study of Chlamydia Trachomatis Using Salicylidene Acylhydrazides as Inhibitors"

The main task in current drug discovery has been the design and growth of new antibacterial drugs with better efficacy and no side effects. We conducted docking simulation to salicylidene acylhydrazides derivatives as ligands into the crystal structure of IncA as the receptor. The 3D crystal structure of IncA as the receptor was downloaded from PDB (Code ID: 6e7e). The structure of ligands and protein were prepared using Spartan and Discovery studio, respectively. The docking process, the interaction, and binding of ligands – protein was done and visualized using iGemdock software and Discovery studio visualizer. The results showed Van der Waals, Pi-donor hydrogen bond, Pi-pi stacked, and amide-pi stacked interaction between compound 44 (N’-[(Z)-(2-hydroxy-3,5-dinitrophenyl)methylidene]-2-[(3R,5S,7s)-adamantan-1-yl]acetohydrazid) with Plk1, but this compound have more Van der Waals interaction with His253, His250, Lys246, Arg245, Thr238 and Ser154 of the crystal structure of IncA as the receptor. iGemdock (drug screening) scores of compounds 44, is -87.3827 kcal/mol. It is predicted that compound 44 has potency as a lead compound to find a new anti-Chlamydia trachomatis candidate for possible therapeutic agents. Biomed
Achieving the Recommended Levels of Physical Activity and Sleep among American Adolescent Athletes.

Background. Few adolescents are getting sufficient levels of physical activity and sleep despite the well understood health benefits of achieving sufficient levels of both, concurrently. This may be related to the limited understanding on the utility of programs to concurrently improve physical activity and sleep in adolescent populations. This study aimed to determine whether sports participation was associated with achieving the recommended levels of sleep and physical activity among a representative sample of American adolescents.Methods. Participants included a representative sample (n=58,008) of American adolescents who self-reported sport-participation (0, 1, 2, 3 or more teams yearly), and recommended levels of physical activity (at least 60-minutes per day of moderate or vigorous intensity physical activity [MVPA], and at least 3-days per week of muscle-strengthening activities [MSA]) and sleep (≤12-13 years: 9 to 10+ hours; 14-17 years: 8-10+ hours; ≥18 years: 7-9 hours). Multivariable logistic regressions were used to estimate the relative odds of meeting the physical activity (MVPA and MSA) and sleep recommendations (independently and in combinations) in sex stratum among those participating in sports versus non-participation.Results. Overall, 49.2% (95%CI: 47.1%-51.4%) of males and 38.6% (95%CI: 37.3%-40.0%) of females report not participating in any sport. Sport-participation differed by sex, age, ethnicity (Hispanic), and weight status. Those who play 1-sport team had higher odds (females: OR=1.95 [95% CI=1.59-2.40]; males: OR=2.20 [1.91-2.52] of concurrently achieving recommendations for sleep and physical activity (MVPA and MSA) compared to those playing no sports teams, after adjustment. Measures of effect were larger for more sports teams played, indicating a possible dose-response relation.Conclusions. Among this representative sample of American adolescents, sports participation was consistently associated with a healthier physical activity and sleep profile. Practitioners should consider encouraging sports participation to adolescents when possible, particularly among females, racial/ethnic minorities, and those with concerns about getting adequate sleep and/or physical activity.
Mechanical Harvest of Broilers

ABSTRACT TEST results from the use of a specially designed long tined scoop mounted on a BobcatrM front-end loader for removal of broilers from a growout facility are reported. An overall reduction in wing and breast bruising was found relative to hand catching. However, some problems were noticed: difficulties in equipment maneuverability, driving over birds in darkness, scoop prongs digging into the litter, and traction difficulties in wet litter. An in-house conveyor system was evaluated. As an alternative to the Bobcat system, various inducements such as a herding device (Jeanie-Walker™) were tried with limited success for moving broilers onto a belt conveyor. Data indicated that this system reduced bruising when compared to hand catching.
Community Ergonomics: Past Approaches and Future Prospects towards America's Urban Crisis

The purpose of this paper is to examine past and current urban programs and to propose a new human engineering approach to solve entrenched problems. The application of a systematic engineering philosophy is central to a process that is focused around the concepts of work. As such, a new application of industrial engineering and human factors is proposed. The creation of stable, worthwhile jobs is crucial, but only in relation to an entire system which includes (among many others) existing governmental programs, educational systems, law enforcement, financial institutions, and especially, people's desires and needs towards bettering their lives. This approach is neither entirely governmental nor privatized. Private industry will be created and encouraged to utilize a non-traditional workforce. Benefits from governmental programs will be utilized to promote an entrepreneurial spirit that can succeed outside of the “underground economy”. In addition, efforts will be coordinated to help people become increasingly independent from hand-outs. The ultimate goal of community ergonomics is to reinvent the “fit” between people, their cities, and society. The development of people and jobs together is vital to this effort. In order for this approach to succeed, programs must propose both empirical research and practical applications.
A study on effects of conducting particles in SF/sub 6/ gas and test methods for GIS

The effects of conducting particles in gas-insulated switchgear (GIS) on insulation performance were investigated. The objective was to recognise the relationship between the length of conducting particles and AC impulse flashover voltages. The data showed that the minimum harmful length of conducting particles at various voltages applied to GIS in service is governed by lightning surge amplitude corresponding to the basic impulse insulation level (BIL). The size of minimum harmful conducting particles was also estimated for various GIS ratings. To further improve the reliability of GIS, factory and on-site test methods are suggested for preventing insulation failures caused by conducting particles. >
Variational Method for the Analysis of Microstrip Lines

This paper reports a method for computing the line capacitance of a microstrip line based on the application of Fourier transform and variational techniques. The characteristic impedance, guide wavelength, and the surface potential distribution in the microstrip line are obtained for a range of structure parameters and the dielectric constant. The results calculated from the expressions developed in the paper are compared with the theoretical results presently available in the literature and good agreement is found. Comparison with available experimental results is also made where feasible. Possible applications and limitations of the method are discussed.

FPGA implementation of multiplierless M-QAM modulator

Adaptive multilevel QAM (M-QAM) modulation can increase throughput in a wireless packet data network. A technique is discussed for efficiently realising M-QAM modulators on field programmable gate arrays (FPGAs) using 'multiplierless' finite impulse response (FIR) filters with carry-save addition and canonic signed-digit coefficients. An adaptive M-QAM modulator supporting 4, 16, 64 and 256-QAM is presented.
SWINE MANURE STORAGE COVERS FOR ODOR CONTROL

Twenty-one, 750-L (200 gal) polyethylene tanks were filled with swine manure. Air samples were collected 24 and 48 h after each manure addition. The samples were tested for odor strength using a dynamic olfactometer and for hydrogen sulfide concentration using a Jerome® meter. The experimental design consisted of a randomized block design containing three blocks (replications) of seven treatments. The seven treatments included no cover (control), straw mat, vegetable oil mat, straw/oil mat, clay ball mat, PVC/rubber membrane, and geotextile membrane. Statistical analysis indicated that all three main effects—cover treatment, collection period, and time after manure addition—significantly (5% level) affected odor units and hydrogen sulfide concentration. Considering all air collections, the six covers reduced odor units and hydrogen sulfide concentration at various points in the study, but not in a consistent manner. The straw mat and PVC/rubber membrane significantly reduced both odors units and hydrogen sulfide concentration consistently 24 h after manure addition during the first three collection periods. Mixing vegetable oil with straw appears to increase longevity of the cover as compared to straw only. The vegetable oil layer, when mixed with the manure, produced a distinctively offensive non-swine odor. The clay ball mat reduced emissions, although not as well as other covers. A geotextile membrane may be a possible cover choice, since the fabric is self-floating and the biofilm that grew on the mat could self-seal the cover. A straw mat (possibly including vegetable oil) and PVC/rubber membrane appear to be the most effective covers in reducing both odors and hydrogen sulfide. Oil alone should not be used as a cover.
MICRO AND SMALL BUSINESS DEVELOPMENT THROUGH INNOVATION AND BUSINESS RISK ADJUSTMENT TOWARD DIGITAL BUSINESS WITH ICT ADOPTION

Technology ICT is highly developed and affect all levels of the business, including micro and small businesses. However, the digital divide problem is still a significant concern among the ASEAN countries. Small mediun enterprises was represent the majority of the business in ASEAN countries that only few of them intensively using ICT as the backbone of their business. The government realized that the benefits of internet technology could not reach the whole people, including the micro and small business. This research wants to evaluate the Micro And Small Business Development through Innovation And Business Risk Adjustment Toward Digital Business with ICT Adoption. The internet access, the speed of acceptance, technology adoption, business exploration, individual motivation, and attitude toward the risk or benefit, is among the variable. This research evaluates those factors, using micro and small enterprises as the research object, and looking at the effect of attitude toward business risk to usage behavior, the impact on the perceived of use and perceived usefulness to their innovation capacity. This paper also showed a new perspective on the technology acceptance model. Based on this paper result, the attitude in taking risks to use technology in developing a business is having a significant influence on small businesses. Culture and the family also influence the owner in making his or her risky decision. This research used quantitative analysis with the TAM model and interviewed 104 traditional small-scale business owners who have limited capital, with low income and run the business on their own. Giving sufficient knowledge to Micro And Small Businesses on the use of ICT will motivate and overcome in making a risky decision and offer an alternative solution to develop their business and reduce the gap of digital divide among business players in ASEAN countries.
Bias in Amplitude Estimation of a Sine Signal with Known Frequency due to the Rounding Quantization Noise

Based on properties of quantization, a method is proposed to derive the bias in amplitude estimation of a sine signal with known frequency due to quantization noise by the rounding quantizer. For a selected quantization unit, the bias oscillates and decays with the signal amplitude, and the period of oscillation is just the quantization unit. Different quantizers may contribute to different biases. A comparison with the bias due to the rounding-down quantizer shows that the difference between them depends on the signal amplitude, and it tends to be small as the signal amplitude increases, not monotonically. Therefore, by choosing appropriate quantizer and quantization unit, the bias in estimated amplitude due to quantization noise will be decreased.
Integration of Building and HVAC Simulation by Elementary Models

Computer simulation is widely used as an analytical tool to evaluate thermal and economical performance of buildings andto improve HVAC control strategies. Many simulation software in use to-day, however, possess internal structures and modelling approaches which restrict their future extension to meet the diversifying needs of the users. To prepare these software for the next generation, much research efforts have been spending on making them fully building and plant integrated, with detailed mathematical representation, and highly flexible in application. A common goal is to achieve an approach to component modelling which offers program inter-operability and helps to converge the disparate theories. A generalised and hierarchical modelling approach using primitive parts (PPs) is one possible solution for this goal. This paper discusses the common features in advanced building thermal simulation software. The PP approach is then introduced as applying to building and plant simulation at various levels.
Analysis of L‐strip proximity fed rectangular microstrip antenna for mobile base station

A wide‐band L‐strip proximity fed rectangular microstrip antenna is proposed and investigated both theoretically and experimentally. The radiating patch is located about 0. 1λ0 (16.5 mm) above the ground plane. The broadband characteristic of antenna is achieved by employing a thick substrate (0.1λ0). Numerical results for the input impedance, VSWR, and co‐ and cross‐polar radiation pattern are presented and compared with the measured results. Good agreement is obtained between computed and measured results. The effects of the geometric parameters of the L‐strip like length of the vertical and horizontal portion of the strip are investigated. It is found that the antenna attains 48.36% impedance bandwidth (SWR ≤ 2) (theoretically) and 56.67% (experimentally) for optimized antenna design. The H‐plane cross‐polarization level is quite high (−16 dB) especially at (computed θ ≈ 60°, and measured θ ≈ 40°) whereas the E‐plane cross‐polarization level is very low. © 2007 Wiley Periodicals, Inc.

Impact of Airport Noise on Property Values

The impact of airport noise on home prices has received much attention in North America, where many hedonic price studies have been performed to examine the issue. In developing countries, however, extremely limited academic work on this topic has been conducted. The recent opening of Suvarnabhumi Airport in Bangkok, Thailand, presented a unique opportunity to address this research gap. In this paper, sales data of new homes near the airport that were sold between 2002 and 2008 are used to examine both the anticipatory effect and actual effects of airport noise on home prices. On the basis of this data set, hedonic price models are estimated and subjected to various diagnostic tests, including those for heteroscedasticity and spatial autocorrelation. The results show no anticipatory effects of airport noise on prices before the beginning of airport operations in 2006. More important, prices of new properties sold after 2006 are 19.15% lower in the most severely affected area and 8.55% lower in moderately affected areas. These estimates imply a noise depreciation index of 2.12% per decibel, which is in the high range of values found in the literature and implies that the potential benefits of a noise reduction program at Suvarnabhumi Airport might be substantial.
Design of SmartGate Technologies for Enhanced Material Handling

The use of information technologies in logistic processes leads to higher automation and efficiency. Nevertheless, information of cargo is often incomplete or incorrect. This affects the material handling processes in planning as well as in operation. This paper presents a SmartGate approach, which contains multiple technologies for identification and exploration of goods for enhanced material handling. This includes identification as well as optic and haptic exploration technologies. The idea is to have a system, which gathers all available information of a good by use of non-destructive testing methods. Besides the optic and haptic exploration technologies, a feasible material handling system and the utilization of the gained information for load planning is shown.
Fabrication and modelling of injection moulded all-polymer capillary microvalves for passive microfluidic control

Rapid prototyping is desirable when developing products. One example of such a product is all-polymer, passive flow controlled lab-on-a-chip systems that are preferential when developing low-cost disposable chips for point-of-care use. In this paper we investigate the following aspects of going from rapid prototyping to pilot (mass) production. (1) Fabrication of an all-polymer microfluidic system using a rapid prototyped master insert for injection moulding and ultrasonic welding, including a systematic experimental characterisation of chip featured geometric capillary microvalve test structures. (2) Numerical modelling of the microvalve burst pressures. Numerical modelling of burst pressures is challenging due to its non-equilibrium nature. We have implemented and tested the level-set method modified with a damped driving term and show that the introduction of the damping term leads to numerically robust results with limited computational demands and a low number of iterations. Numerical and simplified analytical results are validated against the experimental results. We find that injection moulding and ultrasonic welding are effective for chip production and that the experimental burst pressures could be estimated with an average accuracy of 5% using the presented numerical model.
