Mathematical Relationships

According to the indicator diagram of damper, the indicator diagram plumpness was proposed as a quantitative index, and its mathematical relationships with the sprung mass acceleration, suspension dynamic travel and tire dynamic load were built. Moreover, the influence of the total area on suspension characteristics was analyzed in time domain and frequency domain. The results show that, the increase of the indicator diagram plumpness can effectively restrain the variation of suspension dynamic travel and tire dynamic load, meanwhile, the body acceleration will be enlarged. Excessive indicator diagram plumpness also affects the dynamic tire load distribution in frequency domain, and it will decrease the driving security. Therefore, it should be reasonably selected from the performance indicators, which is based on the requirement of vehicle demand in the design process.

Purpose The purpose of this paper is to propose an integrated performance measurement framework to measure the effect of lean implementation throughout all functions of an organization. Design/methodology/approach The paper identifies the seven categories representing all organizational functions. These categories have been divided into 26 performance dimensions and key performance indicators (KPIs) for each performance dimension have been identified to measure lean performance. The interrelationship of each category with lean principles and/or lean wastes has been identified. KPIs are developed on the basis of identified criteria, frequency analysis of existing literature, and discussion with industry professionals. Finally, an integrated performance measurement framework is proposed. Findings The proposed framework evaluates the organization under seven categories – manufacturing process, new product development (NPD), human resource management, finance, administration, customer management, and supplier management. In total, 26 dimensions and 119 key performance indicators have been identified under the seven categories. Research limitations/implications The proposed framework is a conceptual framework and it is to be tested by empirical and cross-sectional studies. Originality/value The main novelty of the research is that the leanness of the organization has been measured throughout the supply chain of the organization in an integrated way. The various areas of measurement are manufacturing process, NPD, finance, administration, customer management, and supplier management. Further, the proposed KPIs are also categorized as qualitative or quantitative, strategic or operational, social or technical, financial or non-financial, leading or lagging, static or dynamic. This paper contributes to the body of knowledge in performance measurement.

Comparative evaluations of design-build (DB), to design-bid-build (DBB), aredocumented in literature. However, a recent study suggests that even though several studies have been completed to compare DB and DBB, there are few statistically significant comparative results. Comparative analyses of highway projects of the same scope, size, and type could provide the basis to make the argument for the use of either DB or DBB on highway projects. The objective of this research is to compare DB to DBB on highway projects. The basis of comparison includes project cost, contract duration, number and type of contract change orders. Projects used for this research were obtained from the Washington State Department of Transportation (WSDOT). The projects were subsequently selected based on project scope,size, and type, and then analysed using quantitative methods. The research found that there is enough evidence to support the use of DB over DBB on highway projects. The findings of this study have significant implications for practitioners and policymakers on highway projects and should inform decisions on the choice of project delivery method. The main limitation of the research is that the study used only 14 projects due to the difficulty of finding matching projects,and as such the results could not be generalized. However, the findings add to the body of research on criteria for comparing DB to DBB. To enhance understanding of how project scope, size, and type might affect or be affected by project delivery methods,the research recommends the standardization of project types classification for highway projects

Global warming has become a problem of world wide, because it endangers living things. The consequences of global warming include the increase of the earth temperature and climate change. The increase of temperature (heating) in a city which is referred to urban heat island (UHI) is also the same problem in architecture. This research aimed to analyze the ambienttemperature of the UHI due to the motor vehicleactivities. Samples were taken from several locations: (1) Bahu Mall Parking area; (2) Manado Town Square 2 parking area; (3) along the Wolter Monginsidi street in front of Bahu Mall and (4) along the Piere Tendean street in front of Manado Town Square. This research used a quantitative method with a field survey. This research found that the ambient temperature increased when motor vehicles were stationary with engine on or moved. The temperature increased due to the heat from the engine and the reflection of the sun’s heat from the body of the vehicles. The heat level obtained from the survey was 34,8 0C to 39,4 0C. For this reason, a specific material for vehicle’s body is needed to prevent the increase of ambient temperature.

This study aimed to provide a description of the continuous recording of the true load regime experienced during daily living by the abutment of a trans-femoral amputee fitted with an osseointegrated fixation. The specific objectives: (i) To present an apparatus and a procedure allowing recording of the load regime, and (ii) an example of the raw data and six performance indicators of the usage of the prosthesis obtained with this method. A subject was monitored for a period of 5 hours as he went about his daily activities. The load regime was directly measured and recorded using a commercial transducer and data logger. The overall load profile presented alternative periods of variable length of inactivity (64%) and activity (36%), respectively. The maximum load applied on the mediolateral, anteroposterior and the long axes represented 21%, 21% and 120% of the body weight, respectively. The anteroposterior, mediolateral and long components of the impulse were 395 kN.s, 359 kN.s and 2,323 kN.s, respectively. The amputee generated a total of 2312 gait cycles of the prosthetic leg, giving an approximate overall cadence of 8 stride/min. Preliminary outcomes indicated that the proposed method was an improvement on the current techniques as it provided the true loading and actual usage of the prosthesis during daily living. This study is a stepping stone in the development of future affordable, on-board and user-friendly load recording systems that can be used in evidence-based practice.

Daily Gain

In dairy cattle breeding, selection and breeding work is widely used in order to transfer the pedigree qualities of parents to the offspring and obtain highly productive young animals. In this regard, in the conditions of «Enbek» LLP in the Akmola region, the growth and development of young Simmental breed depending on the origin was studied. Live weight of Litera line young animals at birth was 33.4 kg, at the age of 6 months-174.9, 12 months-251.8, 18 months-387.1 kg, respectively, Wildfang bull 32.0 kg, 165.5 kg, 251.3 kg, 378.6 kg. The average daily gain between the ages of birth and 6 months was increased. With age, the body parameters, height at the withers, increased from 104.3 cm and 103.5 cm to 125.4 cm and 123.9 cm, respectively, from 6 months to 18 months of young animals. According to the physique indices, we can say that the young Simmental breed is balanced. Only some deviations of the leggy index are observed from the optimal indicators. The index of legginess decreases with age by 7.7%, with indicators of 6 months – by 57%, at the age of 18 months-by 49.3%. The extension index for the period from 6 to 18 months increased by 10.5%, respectively, for 6 months-by 103.3%, for 18 months-by 113.8%. With age and an increase in live weight, the body of young animals lengthens, its width increases, the animal becomes deeper and relatively long-legged. Depending on the origin, we suggest using the Litera bull line, taking into account the growth and development of young animals, and the productivity indicators of bulls.

Adult milkfish (Chanos chanos) swam in a water-tunnel flume over a wide range of speeds. Fish were instrumented with sonomicrometers to measure shortening of red and white myotomal muscle. Muscle strain was also calculated from simultaneous overhead views of the swimming fish. This allowed us to test the hypothesis that the muscle shortens in phase with local body bending. The fish swam at slow speeds [U<2.6 fork lengths s-1 (=FL s-1)] where only peripheral red muscle was powering body movements, and also at higher speeds (2. 6>U>4.6 FL s-1) where they adopted a sprinting gait in which the white muscle is believed to power the body movements. For all combinations of speeds and body locations where we had simultaneous measurements of muscle strain and body bending (0.5 and 0.7FL), both techniques were equivalent predictors of muscle strain histories. Cross-correlation coefficients for comparisons between these techniques exceeded 0.95 in all cases and had temporal separations of less than 7 ms on average. Muscle strain measured using sonomicrometry within the speed range 0.9-2.6 FL s-1 showed that muscle strain did not increase substantially over that speed range, while tail-beat frequency increased by 140 %. While using a sprinting gait, muscle strains became bimodal, with strains within bursts being approximately double those between bursts. Muscle strain calculated from local body bending for a range of locations on the body indicated that muscle strain increases rostrally to caudally, but only by less than 4 %. These results suggest that swimming muscle, which forms a large fraction of the body volume in a fish, undergoes a history of strain that is similar to that expected for a homogeneous, continuous beam. This has been an implicit assumption for many studies of muscle function in many fish, but has not been tested explicitly until now. This result is achieved in spite of the presence of complex and inhomogeneous geometry in the folding of myotomes, collagenous myosepta and tendon, and the anatomical distinction between red and white muscle fibers.

Background:Three-dimensional photonic scanning (3DPS) was recently developed to measuredimensions of a human body surface. Objective:The purpose of this study was to explore the validity of bodyvolume measured by 3DPS for estimating the percent body fat (%fat). Design, setting, participants, andmeasurement:The body volumes were determined by 3DPS in 52 women. The body volume was corrected forresidual lung volume. The %fat was estimated from body density and compared with the corresponding referencevalue determined by the dual-energy x-ray absorptiometry (DXA). Results:No significant difference was foundfor the mean values of %fat obtained by 3DPS (22.2 ± 7.6%) and DXA (23.5 ± 4.9%). The root mean squareerror of %fat between 3DPS and reference technique was 6.0%. For each body segment, there was a significantpositive correlation between 3DPS- and DXA-values, although the corresponding value for the head was slightlylarger in 3DPS than in DXA. Residual lung volume was negatively correlated with the estimated error in %fat.Conclusions:The body volume determined with 3DPS is potentially useful for estimating %fat. A possiblestrategy for enhancing the measurement accuracy of %fat might be to refine the protocol for preparing thesubject’s hair prior to scanning and to improve the accuracy in the measurement of residual lung volume.
