Balancing Mixed-Model Assembly Line To Reduce Work Overload In A Multi-Level Production System, Pravin Y. Tambe
Balancing Mixed-Model Assembly Line To Reduce Work Overload In A Multi-Level Production System, Pravin Y. Tambe
LSU Master's Theses
Generating the optimal production schedule for an assembly line, which will balance the workload at all the production stages, is a difficult task considering a variety of practical constraints. Varying customer demand is an important factor to be considered when designing an assembly line. In order to respond to varying customer demand, many companies are attempting to make their production system more flexible/agile or adaptable to change. Due to the volatile nature of market, companies cannot afford to manufacture same type of product for long period of time and neither can maintain high inventory level; to tackle this problem we …
Effect Of Overhead Drilling Support On Muscular Activity Of Shoulder, Bharat Kumar Bhogaraju Bhallam Venkata
Effect Of Overhead Drilling Support On Muscular Activity Of Shoulder, Bharat Kumar Bhogaraju Bhallam Venkata
LSU Master's Theses
This study examines the effect of an overhead drilling support and position of the arm on muscular activity of the shoulder. Five male participants simulated an overhead drilling task by using a drill in near, middle and far reach positions. Electromyographic measurements were taken from the dominant side anterior deltoid, bicep and trapezius muscles. Root mean square amplitude (RMS) of the EMG activity from these muscles was used to determine the load on the muscular system. The participants used a subjective rating scale to evaluate the overhead support stand and holding position. The results demonstrate that the overhead support stand …
Influence Of Circadian Rhythm On The Physical And Mental Performance, Maryam Muhammed Amin
Influence Of Circadian Rhythm On The Physical And Mental Performance, Maryam Muhammed Amin
LSU Master's Theses
This thesis studied the temperature circadian rhythm and its relationship with the physical and mental performance of the individuals. The objectives of this study were to determine (1) the effect of temperature circadian rhythm on the mental and physical performance, (2) whether a common oral temperature circadian rhythm pattern exists for all the participants, (3) the times of the day when the participants perform their best and worst in comparison to their highest and lowest temperatures respectively, (4) find out whether the effect of the oral temperature circadian rhythm on the physical and mental performance is different in males and …
Grinding Wheel Condition Monitoring With Boosted Classifiers, Fengming Tang
Grinding Wheel Condition Monitoring With Boosted Classifiers, Fengming Tang
LSU Master's Theses
In this thesis, two data sets collected in grinding process under different cutting and wheel conditions were studied. One is the cutting forces in three directions, i.e. X, Y and Z, collected under two different cutting conditions. The other one is the acoustic emission (AE) signals collected under different wheel conditions(sharp and dull). For the goal of grinding wheel condition monitoring, the regression model with autocorrelated errors was proved to be effective and was used to extract features from signals in this study. The coefficients of the models served as the features used in the classification step that employed boosting …
Effect Of Repetitions On Static And Dynamic Strength, Sai Chaitanya Reddy Bogolu
Effect Of Repetitions On Static And Dynamic Strength, Sai Chaitanya Reddy Bogolu
LSU Master's Theses
The objective of this study was to investigate the effect of repetitions on static and dynamic strength. The study is divided into two parts, the first part investigated static and dynamic strength during one, three and six repetitions per minute, and the second part of the study analyzed dynamic strength data collected using the Multiaxial Multipurpose Isokinetic Dynamometer. The study comprised of dynamic strength test data at three speeds of one, five and ten inch per second. Five male subjects participated in the first part of the study, and the results were analyzed by plotting a time series to observe …
