Optimal Planning and Operation of Electric Vehicles Battery Swapping Stations
No full textA Master of Science thesis in Electrical Engineering by Ahmed Ayman Ahmed Shalaby entitled, “Optimal Planning and Operation of Electric Vehicles Battery Swapping Stations”, submitted in May 2020. Thesis advisor is Dr. Mostafa Farouk Shaaban. Soft copy is available (Thesis, Completion Certificate, Approval Signatures, and AUS Archives Consent Form).Electric Vehicles (EVs) nowadays have become increasingly prevalent due to the advancements in EV technology and their impact on reducing greenhouse emissions. However, there are still some factors affecting the fast deployment of EVs such as the limited driving range and the charging time. Due to the limited driving range, EVs need to be charged frequently, but charging requires a long period at traditional EV charging stations, whereas fast-charging stations still have concerns regarding the wait and the charging time, which might cause traffic jams near the station. In this thesis, new dynamic optimal operation and planning approaches of EV battery-swapping stations (BSS) are introduced. In the operation phase, the goal is to maximize the daily profit using a rolling horizon optimization (RHO) mechanism and determining the optimal operating schedule for swapping and charging/discharging processes. The problem is formulated as mixed-integer linear programming (MILP) problem with nonlinear battery degradation characteristics included. Long-short-term memory (LSTM) recurrent neural network is used as a time series forecasting engine for predicting the EVs' arrivals. The proposed approach is tested and compared with the unscheduled operation and day-ahead scheduling. The results show that the dynamic operations scheduling using the proposed RHO mechanism results in a higher profit. In the second phase, an optimal planning approach for a photovoltaic-based BSS system is proposed considering the PV system and EV arrivals uncertainty. The main goal of the planning part is to determine the optimal size of the BSS assets and to optimally allocate the BSS in the distribution network. Markov Chain Monte Carlo Simulation is used to tackle the uncertainty associated with photovoltaic output and EV arrivals. Simulation results show the effectiveness of the proposed BSS system and an optimal solution is obtained which maximizes the annualized profit.College of EngineeringDepartment of Electrical EngineeringMaster of Science in Electrical Engineering (MSEE
Morphometric characteristics of the pelvic limb musculature of Labrador Retrievers with and without cranial cruciate ligament deficiency
No full textObjective: To identify morphometric characteristics of the pelvic limb musculature associated with the development of cranial cruciate ligament (CCL) deficiency in Labrador Retrievers.
Study Design: Cross-sectional clinical study.
Animals:
Pure-bred female (n=18) and male (n=12) Labrador Retrievers with (n=16) and without (n=14) CCL deficiency.
Methods: Muscle conformation of pelvic limbs was evaluated by physical examination, radiography (widths of quadriceps, hamstring, and gastrocnemius were expressed relative to tibial length and to each other), and dual-energy X-ray absorptiometry (DEXA, lean contents of quadriceps, hamstring, and gastrocnemius were expressed relative to tibial length and to each other). Pelvic limbs of dogs without CCL deficiency were classified as normal (n=28 limbs), whereas those with CCL deficiency were considered diseased (n=18 limbs) or sound contralateral to CCL deficiency (n=10 limbs). Variables were compared between groups using mixed models analysis of variance, with P<.05 considered significant.
Results: The ratios of quadriceps width to tibial length (P=.008), hamstring width (P=.013), and gastrocnemius width (P=.005) on lateral radiographs were lower in diseased limbs than controls. The mass of hamstring muscles in CCL deficient limbs was similar to that of normal limbs. The ratio of the lean content of gastrocnemius to hamstring muscles was greater in diseased (P=.007) and sound contralateral (P=.013) limbs than in normal limbs.
Conclusions: Atrophy associated with CCL deficiency may predominantly affect the quadriceps muscle. Dominance of the gastrocnemius muscle over active restraints to the cranial tibial thrust may be associated with predisposition to CCL deficiency in Labrador Retrievers.
Clinical Relevance: If confirmed, this dynamic imbalance between muscle groups of the rear limbs could serve as a basis for screening programs and preventive rehabilitation
Radiographic, computed tomographic, and arthroscopic diagnosis of radioulnar incongruence in dogs with medial coronoid disease
No full textObjective
To characterize radioulnar incongruence (RUI) in large dogs with medial coronoid disease (MCD) and determine the agreement between radiography, computed tomography (CT), and arthroscopy.
Study design
Prospective observational case series.
Animals
Twenty-four large-breed dogs under 3 years of age with confirmed MCD.
Methods
MCD and incongruence were evaluated by radiographs and CT. RUI was measured along the ulnar commissure, mid-body, and apex of the medial coronoid process (MCP) by CT and arthroscopy. Joints with RUI ≥ 2 mm were considered incongruent. Variables recorded during arthroscopic treatment included type of MCD, RUI, and modified Outerbridge score. Agreement between the 3 diagnostic imaging techniques was evaluated, and the association between RUI and cartilage damage was analyzed.
Results
Single fragmentation was the most common MCD according to CT and arthroscopy. RUI was associated with degenerative joint disease according to CT and with cartilage damage according to arthroscopy. RUI was diagnosed in 26% of elbows by radiography, in 35% of elbows by CT, in 78% of elbows according to CT measurements of RUI ≥ 2 mm, and in 57% of joints by arthroscopy. RUI was most commonly detected at the ulnar commissure with CT and at the apex of the MCP with arthroscopy. Imaging modalities were in poor to fair agreement with arthroscopy when evaluating RUI.
Conclusion
CT and arthroscopy provided similar detection of MCD and cartilage disease but disagreed in the assessment and localization of RUI.
Clinical significance
CT does not reliably predict arthroscopic assessment of RUI and associated treatment decisions for MCD
Multivariate analysis of morphometric characteristics to evaluate risk factors for cranial cruciate ligament deficiency in Labrador Retrievers
No full textObjectives: To determine the combination of conformation characteristics of the pelvic limbs of Labrador Retrievers that best discriminates between limb at risk to develop cranial cruciate ligament (CCL) disease and limbs at low risk using radiographs, computerized tomography (CT) images, and dual-energy X-ray absorptiometry (DEXA).
Study Design: Cross-sectional clinical study.
Animals: Twelve clinically normal and 9 unilaterally CCL-deficient Labrador Retrievers.
Methods: The pelvic limbs of normal dogs were considered as non-predisposed to CCL disease and the contralateral limbs of CCL-deficient dogs as predisposed. Conformation variables, obtained from femur and tibial radiographs, pelvic limb CT images and DEXA studies, of predisposed pelvic limbs were compared with the conformation variables from pelvic limbs of the low-risk group. An ROC curve analysis was used to assess the discriminating properties of conformation variables for several combinations.
Results: We determined that a combination of tibial plateau angle (TPA) and femoral anteversion angle (FAA) measured on radiographs was optimal for discriminating predisposed and non-predisposed limbs for CCL disease in Labrador Retrievers.
Conclusions: Assessing predisposition to CCL disease with a combination of conformational measurements is better than using univariate parameters. In the future, TPA and FAA may be used to screen dogs suspected of being susceptible to CCL disease
Radiographic evaluation of femoral torsion and correlation with computed tomographic techniques in Labrador Retrievers with and without cranial cruciate ligament disease
No full textObjectives
To (1) develop a technique to determine the anteversion angle (AA) of the femur on a single radiograph; (2) determine the correlation between this technique and other published radiographic and computed tomographic (CT) methods; and (3) compare the diagnostic outcome of these methods in determining the level at which femoral torsion occurred in Labrador Retrievers with cranial cruciate ligament (CCL) deficiency.
Study Design
Cross-sectional clinical study.
Animals
Mature pure-bred Labrador Retrievers (n = 30).
Methods
Pelvic limbs (n = 28) of 14 dogs without CCL deficiency were classified as control, whereas limbs of 16 dogs (18 limbs) with CCL deficiency were considered as diseased. Femoral torsion was evaluated using radiography and CT and variables were compared among limb groups by use of a mixed-model ANOVA, with P < .05 considered significant.
Results
There was a significant association between biplanar and lateral plane AAs but neither correlated with CT assessment of femoral torsion. On CT, a significant correlation was identified between overall AA and each of the distal, proximal, and femoral head trochanteric angles. Biplanar and lateral plane AAs did not differ between normal and CCL deficient limbs. On CT, overall and distal AAs were increased in CCL deficient limbs compared to control.
Conclusion
Biplanar determination of femoral torsion can be estimated based on a single lateral radiograph but the results will be inaccurate as only CT identified and localized the site of femoral torsion
