Abstract:
Basic services for power business were provided by the power multimodel network providers. However, because the power multimodal network is usually complex and changeable, the service of power business is often unstable. This problem can be solved by a suitable network resource optimization method. Therefore, how to design a network resource optimization method that seeks a compromise between multiple performance indicators that achieve the normal operation of power multimode networks is still extremely challenging. An optimal allocation method of power multimodal network resources based on NSGA-II was proposed by this paper. Firstly, the power multimodal network-resource model is established, and the problems existing in the resource optimization process are analyzed. Secondly, preprocessing technology and indirect coding technology are applied to NSGA-II, which solves the coding problem and convergence problem of the application of genetic algorithm to the optimization of network resource allocation. Finally, the simulation results show that, compared with the control algorithm, this method has further optimized the various indicators of the resource allocation of the power multimodal network, and the performance has been improved by more than 6%.

Abstract:
L’objectif général de ce projet de thèse est le développement industriel de source lasers accordables de haute cohérence à base de technologies III-V dans les gammes spectrales 0.95-1.1µm, et 2-2.5µm. Ce travail est le fruit d'un partenariat entre les laboratoires IES et C2N, avec la société INNOPTICS spécialisée dans l'intégration de composant opto-électronique.Il s'agit ici de tirer profit des nombreux avantages des composants VeCSELs (Vertical external Cavity Surface Emitting Laser) pour atteindre une combinaison des performances cohérence - puissance - accordabilité - compacité, inaccessible avec les technologies laser commerciales d'aujourd'hui. Pour atteindre cet objectif le travail est scindé en deux grandes parties :- L'étude physique de la dynamique non linéaire d'un laser VECSEL en régime continu et en présence de dispersion de phase. Nous montrons l'existence d'une dynamique déterministe du champ laser qui donne naissance à un régime multimode longitudinal non stationnaire régulier ou à un régime mono-fréquence stable. Ce résultat permet alors la conception de source de haute cohérence à forte puissance sans élément intracavité sélectif en longueur d'ondes.- Le développement de nouvelles sources monofréquences compact largement accordables bas bruit avec une largeur de raie étroite. Cette partie comporte l’étude physique des composants, depuis l’optimisation du milieu à gain jusqu'à l'émission laser en terme de cohérence spatiale et temporelle, ainsi qu'un travail sur l'environnement du laser (mécanique et thermique optimisée pour la stabilité de la fréquence laser)<br>The main goal of this thesis is the industrial development of highly coherent tunable laser sources based on III-V technologies in the 0.95-1.1μm and 2-2.5μm spectral ranges.This work is the result of a partnership between the IES and C2N laboratory together with the company INNOPTICS, specialized in the packaging of optoelectronics devices.We take advantage of the Vertical External Cavity Surface Emitting Laser (VECSEL) technology to achieve a combination of coherence - power -tunability -compactness, overcoming the performances of today's commercial laser technologies. To achieve this goal the work is divided into two main parts:- The physical study of the non-linear dynamics of a VECSEL laser in continuous wave operation and in the presence of cavity phase dispersion. We show the existence of a deterministic dynamics of the laser field that gives rise to a regular non-stationary longitudinal multimode regime or a stable single-frequency regime. This result then makes it possible to design a source of high coherence with high power without any intracavity wavelength selective element.- The development of new low noise compact single frequency sources with a narrow linewidth. This part involves the physical study of the components, from optimization of the gain medium to the laser emission in terms of spatial and temporal coherence, as well as a work on the environment of the laser (optimization of the thermal mechanical properties of the packaging for the stability of the laser frequency)

DeckAssistant has a large digital tabletop display that shows the status of the deck and has an understanding of certain deck actions for scenario planning. To preserve the conventional way of interacting with the old-school Ouija board where deck handlers move aircraft by hand, the system takes advantage of multiple modes of interaction. Deck handlers plan strategies by pointing at aircraft, gesturing and talking to the system. The system responds with its own speech and gestures, and it updates the display to show the consequences of the actions taken by the handlers. The system can also be used to simulate certain scenarios during the planning process. The multimodal interaction described here creates a communication of sorts between deck handlers and the system. Our contributions include improvements in hand-tracking, speech synthesis and speech recognition.<br>by Birkan Uzun.<br>M. Eng.

Abstract:
Cette thèse est une contribution aux travaux de recherche sur l’optimisation des problèmes du transport multimodal. Les principaux concepts clé de la multimodalité dans les réseaux du transport intermodal et l’état de l’art des travaux scientifique du domaine y sont présentés. Le problème de la localisation des terminaux du transport combiné est ensuite étudié. Nous proposons un algorithme génétique à codage mixte pour la résolution de ce problème et nous comparons nos résultats avec ceux de la littérature. Un ensemble de problèmes posés dans le cadre de notre travail sur le projet DCAS (Direct Cargo Axe Seine), porté par le Grand Port Maritime du Havre, y est décrit et modélisé par des outils de programmation mathématique. Ainsi, nous avons étudié le problème du transfert de navettes ferroviaires qui consiste à optimiser le transfert d’un ensemble de conteneurs entre des terminaux maritimes et un terminal multimodal. Ensuite, nous avons modélisé le problème d’ordonnancement des trains de grandes de lignes pour le placement sur les voies de la cour ferroviaire du terminal multimodal du Havre. Ces problèmes sont résolus en utilisant une approche combinée optimisation-simulation. Une première application est basée sur un algorithme génétique couplé avec la simulation multi agents pour l’affectation des voies aux trains. Une deuxième, consiste à optimiser la manutention des conteneurs lors d’un transbordement rail-rail en utilisant un algorithme de colonie de fourmis intégré dans le modèle de simulation et une stratégie de collaboration agents pour minimiser les temps d’attente des portiques et ainsi augmenter leurs productivités<br>This thesis is a contribution to research on the optimization of multimodal transport problems. The main key concepts of multimodality in the intermodal transportation networks and the state of the art of scientific works in the field are presented. The intermodal terminal location problem is then studied. We propose a genetic algorithm with mixed encoding for solving this problem and we compare our results with those of literature. A set of problems in the framework of our work on the project DCAS (Direct Cargo Axe Seine), carried by the Grand Port Maritime du Havre, are described and modeled by mathematical programming tools. Thus, we studied the problem of the transfer of rail shuttles which is to optimize the transfer of a set of containers between maritime terminals and a multimodal terminal. We then modeled the scheduling problem of freight trains for placement on rail tracks. These problems are solved by using combined optimization simulation approaches. A first application is based on a genetic algorithm coupled with the multi agent’s simulation. A second is to optimize a rail-rail transshipment of containers using an ant colony algorithm embedded in the simulation model and an agent’s collaboration strategy to minimize waiting times and increase cranes productivity.541 ##‎$a@Optimization of multimodal transportation problems

Abstract:
Gateways in emerging megaregions have the available transport infrastructure that could support modal shift and sustainable development and more could be made of them. A gateway is not a defined administration area but rather a functional economic area. Typically it has some port, airport, rail hub and logistics clusters and is key to the regional economy. Existing policies try to achieve an optimisation of the performance of multimodal logistic chains and transport infrastructure, including making greater use of inherently more resource efficient modes, where other technological innovations may be insufficient (e.g. long-distance freight). Emerging megaregions rely heavily on global logistics operations to supply their population, the majority of which is living in metropolitan areas with a higher concentration of greenhouse gases and a heavy concentration of multiple-layer logistics and transport operations, and other urban functions. To address these issues, there is a need for more efficient traffic management solutions, a stronger shift away from road transportation towards more environmentally friendly modes both for freight and for passengers but most importantly the adoption of an integrated methodological approach when assessing existing and planned transport infrastructure by the decision makers with respect to sustainable development. This research provides a novel approach to the literature of performance evaluation of modal shift and transport infrastructure service quality by capturing the involved stakeholders' perceptions and expectations. The application and combination of the importanceperformance analysis (IPA) and analytical hierarchical process (AHP) model in an intermodal transport infrastructure regional case study provides a straightforward methodology for the assessment of sustainable development as a result of an industrial survey. In addition added value is provided to the literature for long term scenarios' planning for sustainable transport infrastructure.

Abstract:
Abstract Purpose: is to identify the challenges of multimodal transport service of ESLSE in the Europe trade routes operation from origin up to destination and to analyze the contribution of network partners to ESLSE solving these challenges.   Design\Data collection\Approach: This thesis relied on qualitative research design in order to identify the key challenges of multimodal transport services and to show how the network partners contribute to solving these challenges. Moreover, to achieve the objective of the study, semi structure interviews were used, and the responses from 14 experts were analyzed.   Theoretical framework: The theoretical base and concepts are used to determine the theoretical boundaries of the research. It provides an overview of the literature that exists in the challenges of multimodal transport services. The theoretical framework firstly encompassed the logistics performance and personnel, followed by the description of multimodal transport services, customs facilitation, ICT, infrastructure, network partner integration and port administration. Lastly, theoretical synthesis is developed that are identified from the theory to demonstrate the interrelationship between individual concepts.   Findings: The findings of this study revealed that multimodal transport service was impacted by a number of challenges even if the network partners contributed some solutions. The results of the study showed that the lack of skilled logistics personnel; poor ICT system; lack of integration between network partners; lack of effective infrastructure; inadequate and ineffective capacity of trucks; material theft; corruption; security risk; lack of prompt response in the operation between network partners; monopoly of the operation by ESLSE; and lack of quality of transported cargo are the main challenges for multimodal transport services. Managerial implication: For managers of network partners, it is recommended that they should be aware that the challenge of multimodal transport service is the result of poor ICT systems; lack of integration between network partners; lack of effective infrastructure; lack of skilled logistic personnel; inadequate and ineffective capacity of trucks; material theft; corruption; security risk; lack of quality of transported cargo; and lack of prompt response in the operation between the network partners Hence, they should take action to solve the problems by integrating with shipping agents and steering committees such as customers office, transport minister, and maritime authority. Moreover, the shipping agents managers can use the results of the study to enhance their contribution in order to solve the challenges of multimodal transport services by communicating with the ESLSE.   Limitations: The small sample size without adequately diverse geographical spread and sample of shipping agents and dry ports since the study is only limited to Europe trade routes and it did not take in to consideration other continents like Africa and Asia which could have given additional information on the topic. The sample of shipping agent and dry ports was limited with 3 out of 11 and 3 out of 7 respectively.   Originality\Value: This thesis is one of the first to analyze the challenges of multimodal transport in the case of Ethiopia to Europe trade operation by interviewing both the ESLSE and shipping agents.

Abstract:
Bus systems have a large passenger capacity when compared to personal vehicles and thus have the potential to improve urban mobility. However, buses that operate in mixed vehicle traffic can undermine the effectiveness of the road system as they travel at lower speeds, take longer to accelerate and stop frequently to board and alight passengers. In traffic flow theory, buses are known as slow-moving bottlenecks that have the potential to create queue-spillbacks and thus increase the probability of gridlock. Currently, traditional metropolitan transportation planning models do not account for these negative effects on roadway capacity. Also, research methods that study multimodal operations are often simulated or algorithmic which can only provide specific results for defined inputs. The objective of this research is to model and understand the effects of bus operations (e.g., headway, number of stops, number of routes) on system performance (e.g. urban corridor and network vehicular capacity) using a parsimonious analytical approach with a few parameters.The models are built using the Macroscopic Fundamental Diagram (MFD) of traffic which provides aggregate measures of vehicle density and flow. Existing MFD theory, which accounts for corridors with only one vehicle class are extended to include network roadway systems and bus operations. The results indicate that buses have two major effects on corridors: the moving bottleneck and the bus short-block effect. Also, these corridor effects are expanded to urban networks through a vehicle density-weighted average. The models have the potential to transform urban multimodal operations and management as they provide a simple tool to capture aggregate performance of transportation systems.

Abstract:
This chapter provides a preliminary account of different figurative operations in twelve examples of program classical and contemporary music involving music and text. The main goals are to explore the directionality and scope of the mappings between language and music and to investigate the communicative effects of each operation in a musical work. Metonymy, metaphor, hyperbole, paradox, and irony are compared and contrasted to highlight the dynamism and flexibility of conceptual mechanisms to account for meaning construction in multimodal contexts. Although all these conceptual tools consist of putting in correspondence two entities, there are differences that allow us to draw boundaries among them. The main advantage of adopting a view based on figurative operations is that they overcome the two-domain layout of metaphors while counting on a limited inferential capacity that allows the prediction of possible communicative effects.

Evaluation of Left Shoulder as Part-Time Travel Lane Design Alternatives and Transportation Management Center Staff Training Module Development.

Abstract:
Permanent capacity expansion, such as adding new lanes, is no longer a viable strategy to address traffic congestion in California; hence, ITS (Intelligent Transportation System) strategies, such as part-time use of the shoulder as a travel lane, need to be explored. The use of the shoulder as a travel lane during peak traffic hours has limited applications in the US, and most use the right shoulder as a part-time travel lane even though either the right or left shoulder (but not both) may be used. Caltrans District 5 is exploring the use of Left Shoulder as a Part-time Travel Lane (LSPTTL) as a piece of the larger project, titled Five Cities Multimodal Transportation Network Enhancement Project (FCMTNEP), aimed at congestion relief near Pismo Beach, CA. Construction is expected to begin in Winter 2025 with a Winter 2027 completion date. Given that this would be the first instance of LSPTTL in California, it is a Project of Division Interest (PoDI) for the California division of Federal Highway Administration (FHWA), and the District 5 experience may guide similar future installations of the shoulder as travel lane projects in the state. This research uses a microsimulation-based approach to evaluate design alternatives being explored by Caltrans District 5. This approach allows for evaluating the operational and safety effects of each of the alternatives. Furthermore, a Transportation Management Center (TMC) operator training framework has also been developed to ensure that the local TMC personnel can effectively deploy the LSPTTL during routine operations and emergencies. Based on the operational evaluation, the study found no significant difference in travel times associated with the three design alternatives. Alternative 2, which involves the longest segment with LSPTTL among the alternatives, was found to be the safest based on a surrogate safety measure-based evaluation. This framework for evaluating design alternatives for operations and safety effectiveness may be used for future projects that involve the use of the shoulder as a travel lane. For TMC operator training, this report documents key learning objectives. A hands-on training program that involves operators executing the opening and closing of the shoulder for routine and emergency conditions was developed. As the project nears implementation, there is some scope for improvement in the training modules through replication of the exact features of the LSPTTL design and introducing more realism in the TMC simulator training exercises.

Full text
Abstract:
The rapid growth in population and related demand for travel during the past few decades has had a catalytic effect on traffic congestion, air quality, and safety in many urban areas. Transportation managers and planners have planned for new facilities to cater to the needs of users of alternative modes of transportation (e.g., public transportation, walking, and bicycling) over the next decade. However, there are no widely accepted methods, nor there is enough evidence to justify whether such plans are instrumental in improving mobility of the transportation system. Therefore, this project researches the operational performance of urban roads with heterogeneous traffic conditions to improve the mobility and reliability of people and goods. A 4-mile stretch of the Blue Line light rail transit (LRT) extension, which connects Old Concord Rd and the University of North Carolina at Charlotte’s main campus on N Tryon St in Charlotte, North Carolina, was considered for travel time reliability analysis. The influence of crosswalks, sidewalks, trails, greenways, on-street bicycle lanes, bus/LRT routes and stops/stations, and street network characteristics on travel time reliability were comprehensively considered from a multimodal perspective. Likewise, a 2.5-mile-long section of the Blue Line LRT extension, which connects University City Blvd and Mallard Creek Church Rd on N Tryon St in Charlotte, North Carolina, was considered for simulation-based operational analysis. Vissim traffic simulation software was used to compute and compare delay, queue length, and maximum queue length at nine intersections to evaluate the influence of vehicles, LRT, pedestrians, and bicyclists, individually and/or combined. The statistical significance of variations in travel time reliability were particularly less in the case of links on N Tryon St with the Blue Line LRT extension. However, a decrease in travel time reliability on some links was observed on the parallel route (I-85) and cross-streets. While a decrease in vehicle delay on northbound and southbound approaches of N Tryon St was observed in most cases after the LRT is in operation, the cross-streets of N Tryon St incurred a relatively higher increase in delay after the LRT is in operation. The current pedestrian and bicycling activity levels seemed insignificant to have an influence on vehicle delay at intersections. The methodological approaches from this research can be used to assess the performance of a transportation facility and identify remedial solutions from a multimodal perspective.

Abstract:
Recent developments in transformative technologies hold the promise to provide holistic solutions for affordable transportation services to rural areas and thus greatly alleviate existing social inequality through efficient planning and management of complex transportation systems and systemwide interactions among multiple modes. To realize the promise, many challenging research questions need to be addressed, which often leads to computationally intractable, large-scale, dynamic/stochastic, discrete optimization models. This project proposes to address some of the challenges by building a series of holistic and tractable models on the design of mobility services, capacity planning, dynamic matching, and routing, as well as pricing. The proposed project is expected to create a new series of planning and management models that can support strategical and operational decisions for large-scale autonomous and shared mobility systems in rural areas. The planned case study and simulation for the Village of Rantoul, Illinois, will lay the foundation for future field implementation.

Full text
Abstract:
This paper investigates the feasibility of using non-cerebral, time-series data to detect epileptic seizures. Data were recorded from fifteen patients (7 male, 5 female, 3 not noted, mean age 36.17 yrs), five of whom had a total of seven seizures. Patients were monitored in an inpatient setting using standard video electroencephalography (vEEG), while also wearing sensors monitoring electrocardiography, electrodermal activity, electromyography, accelerometry, and audio signals (vocalizations). A systematic and detailed study was conducted to identify the sensors and the features derived from the non-cerebral sensors that contribute most significantly to separability of data acquired during seizures from non-seizure data. Post-processing of the data using linear discriminant analysis (LDA) shows that seizure data are strongly separable from non-seizure data based on features derived from the signals recorded. The mean area under the receiver operator characteristic (ROC) curve for each individual patient that experienced a seizure during data collection, calculated using LDA, was 0.9682. The features that contribute most significantly to seizure detection differ for each patient. The results show that a multimodal approach to seizure detection using the specified sensor suite is promising in detecting seizures with both sensitivity and specificity. Moreover, the study provides a means to quantify the contribution of each sensor and feature to separability. Development of a non-electroencephalography (EEG) based seizure detection device would give doctors a more accurate seizure count outside of the clinical setting, improving treatment and the quality of life of epilepsy patients.

Full text
Abstract:
The expansion of metropolitan areas in California has further prompted the need to improve transportation options for all, more effectively linking origins and destinations through key enhancements to the existing network of transit services. This study provides planners and policymakers examples of effective regional transit coordination agencies. To improve multimodal connections and enhance transit services at the local and regional levels, this study explores regional coordination, focusing on entities charged with coordinating multiple transit agencies in a single metropolitan area. The study identified 16 regional transit coordinators (RTCs), identifying the structure, scope, and management of each. The results revealed that there are many factors involved in creating an organization with the authority to coordinate regional transit, including how the organization was established and elements related to the formation of an RTC (e.g., regional dynamics and board composition). It is also important to study the powers vested in different types of boards and members, as well as the executive director. There is a wide range of state legislation for the legal establishment of RTCs. Voluntary transit federations, another option, fall into two categories: loose federations, based on consensus and strong federations, based on binding arrangements to coordinate fares, services, and information. The authors offer options for establishing an RTC in California, including a multi-county owned corporation with an ex officio board; an agency of the state or regional government; and a special district with an ex officio board representing counties, cities, planning staff, operator staff, and state transport agencies. Finally, suggestions for creating the board are provided along with a recommendation that the state develop a legislative framework to establish RTCs in its metropolitan areas.

Full text
Abstract:
Original objectives and revisions – The original overall objective was to develop, test and validate a prototype yield mapping system for unit area to increase yield and profit for tree crops. Specific objectives were: (1) to develop a yield mapping system for a static situation, using hyperspectral and thermal imaging independently, (2) to integrate hyperspectral and thermal imaging for improved yield estimation by combining thermal images with hyperspectral images to improve fruit detection, and (3) to expand the system to a mobile platform for a stop-measure- and-go situation. There were no major revisions in the overall objective, however, several revisions were made on the specific objectives. The revised specific objectives were: (1) to develop a yield mapping system for a static situation, using color and thermal imaging independently, (2) to integrate color and thermal imaging for improved yield estimation by combining thermal images with color images to improve fruit detection, and (3) to expand the system to an autonomous mobile platform for a continuous-measure situation. Background, major conclusions, solutions and achievements -- Yield mapping is considered as an initial step for applying precision agriculture technologies. Although many yield mapping systems have been developed for agronomic crops, it remains a difficult task for mapping yield of tree crops. In this project, an autonomous immature fruit yield mapping system was developed. The system could detect and count the number of fruit at early growth stages of citrus fruit so that farmers could apply site-specific management based on the maps. There were two sub-systems, a navigation system and an imaging system. Robot Operating System (ROS) was the backbone for developing the navigation system using an unmanned ground vehicle (UGV). An inertial measurement unit (IMU), wheel encoders and a GPS were integrated using an extended Kalman filter to provide reliable and accurate localization information. A LiDAR was added to support simultaneous localization and mapping (SLAM) algorithms. The color camera on a Microsoft Kinect was used to detect citrus trees and a new machine vision algorithm was developed to enable autonomous navigations in the citrus grove. A multimodal imaging system, which consisted of two color cameras and a thermal camera, was carried by the vehicle for video acquisitions. A novel image registration method was developed for combining color and thermal images and matching fruit in both images which achieved pixel-level accuracy. A new Color- Thermal Combined Probability (CTCP) algorithm was created to effectively fuse information from the color and thermal images to classify potential image regions into fruit and non-fruit classes. Algorithms were also developed to integrate image registration, information fusion and fruit classification and detection into a single step for real-time processing. The imaging system achieved a precision rate of 95.5% and a recall rate of 90.4% on immature green citrus fruit detection which was a great improvement compared to previous studies. Implications – The development of the immature green fruit yield mapping system will help farmers make early decisions for planning operations and marketing so high yield and profit can be achieved.

Abstract:
The Illinois Marine Transportation System (IMTS) is a key component of the nation’s inland waterway system. IMTS is comprised of 27 locks and dams, 19 port districts, more than 350 active terminals, and 1,118 miles of navigable inland waterways traversing along the borderline or within the state of Illinois. However, the infrastructure of IMTS is aging and its conditions are deteriorating. To monitor the performance of IMTS and guide infrastructure investment to enhance safety, efficiency, and reliability of the system, a comprehensive performance measurement program is needed. To this end, the objective of this project is to create an integrated, comprehensive, and maintainable database that facilitates performance measurement of maritime freight to, from, and through Illinois. To achieve this objective, a review of the literature on maritime freight transportation both in the United States and abroad was performed. To gauge practitioners’ points of view, a series of phone interviews and online surveys of Illinois’ neighboring state DOT officials, officials from the US Army Corps of Engineers, Illinois port district authorities, and carriers operating in Illinois was also conducted. With the findings from the literature review and an understanding of state DOT practices, the needed and available data sources for a maritime freight performance measurement program were identified. Building on all the above efforts, a first-of-its-kind PM database for IMTS was designed and developed, along with a detailed user manual, ready for IDOT’s immediate use and future updates. In addition, opportunities for IDOT to use the database to conduct analysis are discussed. Key programmatic recommendations that outline the role of IDOT as a champion and as a facilitator are further included. The outcome of this project will help IDOT gain much-needed knowledge of and develop programs to improve IMTS performance, increase multimodal transportation network capacity, and expand the transportation and logistics sector of the state, which ultimately benefit the people and economy of Illinois.

Abstract:
Background Opioid analgesia has become the mainstay for acute pain management in the postoperative setting. However, the use of opioid medications comes with significant risks and side effects. Due to increasing numbers of prescriptions to those with chronic pain, opioid medications have become more expensive while becoming less effective due to the buildup of patient tolerance. The idea of opioid-free analgesic techniques has rarely been breached in many hospitals. Emerging research has shown that opioid-sparing approaches have resulted in lower reported pain scores across the board, as well as significant cost reductions to hospitals and insurance agencies. In addition to providing adequate pain relief, the predicted cost burden of an opioid-free or opioid-sparing approach is significantly less than traditional methods. Methods The following groups were considered in our inclusion criteria: those who speak the English language, all races and ethnicities, male or female, home medications, those who are at least 18 years of age and able to provide written informed consent, those undergoing inpatient or same-day surgical procedures. In addition, our scoping review includes the following exclusion criteria: those who are non-English speaking, those who are less than 18 years of age, those who are not undergoing surgical procedures while admitted, those who are unable to provide numeric pain score due to clinical status, those who are unable to provide written informed consent, and those who decline participation in the study. Data was extracted by one reviewer and verified by the remaining two group members. Extraction was divided as equally as possible among the 11 listed references. Discrepancies in data extraction were discussed between the article reviewer, project editor, and group leader. Results We identified nine primary sources addressing the use of ketamine as an alternative to opioid analgesia and post-operative pain control. Our findings indicate a positive correlation between perioperative ketamine administration and postoperative pain control. While this information provides insight on opioid-free analgesia, it also revealed the limited amount of research conducted in this area of practice. The strategies for several of the clinical trials limited ketamine administration to a small niche of patients. The included studies provided evidence for lower pain scores, reductions in opioid consumption, and better patient outcomes. Implications for Nursing Practice Based on the results of the studies’ randomized controlled trials and meta-analyses, the effects of ketamine are shown as an adequate analgesic alternative to opioids postoperatively. The cited resources showed that ketamine can be used as a sole agent, or combined effectively with reduced doses of opioids for multimodal therapy. There were noted limitations in some of the research articles. Not all of the cited studies were able to include definitive evidence of proper blinding techniques or randomization methods. Small sample sizes and the inclusion of specific patient populations identified within several of the studies can skew data in one direction or another; therefore, significant clinical results cannot be generalized to patient populations across the board.
